6 * Version 3.3.27 (released 2017-03-06)
8 ** libgnutls: read the pin-value attribute if the p11-kit version allows it.
10 ** libgnutls: Addressed integer overflow resulting to invalid memory write
11 in OpenPGP certificate parsing. Issue found using oss-fuzz project:
12 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=420 [GNUTLS-SA-2017-3A]
14 ** libgnutls: Addressed crashes in OpenPGP certificate parsing, related
15 to private key parser. No longer allow OpenPGP certificates (public keys)
16 to contain private key sub-packets. Issue found using oss-fuzz project:
17 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=354
18 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=360 [GNUTLS-SA-2017-3B]
20 ** libgnutls: Addressed large allocation in OpenPGP certificate parsing, that
21 could lead in out-of-memory condition. Issue found using oss-fuzz project,
22 and was fixed by Alex Gaynor:
23 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=392 [GNUTLS-SA-2017-3C]
25 ** API and ABI modifications:
26 No changes since last version.
29 * Version 3.3.26 (released 2016-01-09)
31 ** libgnutls: Handle status request responses as optional (following
32 RFC6066). This improves compatibility with implementations not sending
33 these messages (including specific versions on the GnuTLS 3.5.x branch).
35 ** libgnutls: Set limits on the maximum number of alerts handled. That is,
36 applications using gnutls could be tricked into an busy loop if the
37 peer sends continuously alert messages. Applications which set a maximum
38 handshake time (via gnutls_handshake_set_timeout) will eventually recover
39 but others may remain in a busy loops indefinitely. This is related but
40 not identical to CVE-2016-8610, due to the difference in alert handling
41 of the libraries (gnutls delegates that handling to applications).
43 ** libgnutls: Fixed issue in PKCS#12 password encoding, which truncated
44 passwords over 32-characters. Reported by Mario Klebsch.
46 ** libgnutls: Backported functionality allowing to manipulate the IDs
49 ** libgnutls: Link to trousers (TPM library) dynamically. Backported TPM
50 key handling improvements from master branch.
52 ** libgnutls: Backported several fixes in PKCS#8 decryption (related to
55 ** libgnutls: Fix double free in certificate information printing. If the PKIX
56 extension proxy was set with a policy language set but no policy specified,
57 that could lead to a double free. [GNUTLS-SA-2017-1]
59 ** libgnutls: Addressed memory leak in server side error path
60 (issue found using oss-fuzz project)
62 ** libgnutls: Addressed memory leaks and an infinite loop in OpenPGP certificate
63 parsing. Fixes by Alex Gaynor. (issues found using oss-fuzz project)
65 ** libgnutls: Addressed invalid memory accesses in OpenPGP certificate parsing.
66 (issues found using oss-fuzz project) [GNUTLS-SA-2017-2]
68 ** tpmtool: backported the --test-sign option.
70 ** API and ABI modifications:
71 gnutls_pkcs11_obj_set_info: Added
72 gnutls_pkcs11_privkey_generate3: Added
73 gnutls_pkcs11_copy_x509_privkey2: Added
74 gnutls_pkcs11_copy_x509_crt2: Added
77 * Version 3.3.25 (released 2016-10-9)
79 ** libgnutls: Ensure proper cleanups on gnutls_certificate_set_*key()
80 failures due to key mismatch. This prevents leaks or double freeing
83 ** libgnutls: Corrected the comparison of the serial size in OCSP response.
84 Previously the OCSP certificate check wouldn't verify the serial length
85 and could succeed in cases it shouldn't (GNUTLS-SA-2016-3).
86 Reported by Stefan Buehler.
88 ** libgnutls: Fixes in gnutls_x509_crt_list_import2, which was
89 ignoring flags if all certificates in the list fit within the
90 initially allocated memory.
92 ** libgnutls: Fix gnutls_pkcs12_simple_parse to always extract the complete chain,
93 even when the extra_certs was non-null. Report and fix by Stefan Sørensen.
95 ** libgnutls: Added support for decrypting PKCS#8 files which use the HMAC-SHA256
98 ** libgnutls: Addressed issue with PKCS#11 signature generation on ECDSA
99 keys. The signature is now written as unsigned integers into the DSASignatureValue
100 structure. Previously signed integers could be written depending on what
101 the underlying module would produce. Addresses #122.
103 ** libgnutls: backported X.509 unique ID functionality from later versions.
105 ** libgnutls: Increased the maximum size of the handshake message hash.
106 This will allow the library to cope better with larger packets, as
107 the ones offered by current TLS 1.3 drafts.
109 ** API and ABI modifications:
110 gnutls_x509_crt_set_issuer_unique_id: Added
111 gnutls_x509_crt_set_subject_unique_id: Added
114 * Version 3.3.24 (released 2016-07-06)
116 ** libgnutls: Address issue when utilizing the p11-kit trust store
117 for certificate verification (GNUTLS-SA-2016-2).
119 ** libgnutls: when generating private keys mark the public key as not
122 ** libgnutls: use secure_getenv() where available to obtain environment
125 ** libgnutls: Fixed DTLS handshake packet reconstruction. Reported by
128 ** libgnutls: Fixed issues with PKCS#11 reading of sensitive objects
129 from SafeNet Network HSM. Reported by Anthony Alba.
131 ** libgnutls: Corrected reading and writing of PKCS#11 CKA_SERIAL_NUMBER. Report
132 and fix by Stanislav Židek.
134 ** libgnutls: Enhanced the priority functions to understand -VERS-ALL keyword
135 to allow compatibility of priority strings between 3.4.x and 3.3.x.
137 ** API and ABI modifications:
138 No changes since last version.
141 * Version 3.3.23 (released 2016-05-20)
143 ** libgnutls: Corrected behavior of ALPN extension parsing during session
144 resumption. Report and patches by Yuriy M. Kaminskiy.
146 ** libgnutls: Properly print the IP Adress name constraints.
148 ** libgnutls: Fixes in gnutls_privkey_import_ecc_raw().
150 ** libgnutls: Fixed gnutls_pkcs11_get_raw_issuer() usage with the
151 GNUTLS_PKCS11_OBJ_FLAG_OVERWRITE_TRUSTMOD_EXT flag. Previously that
152 operation could fail on certain PKCS#11 modules.
154 ** libgnutls: gnutls_pkcs11_obj_import_url() and gnutls_x509_crt_import_pkcs11_url()
155 can accept the GNUTLS_PKCS11_OBJ_FLAG_OVERWRITE_TRUSTMOD_EXT flag.
157 ** libgnutls: gnutls_certificate_set_key() was enhanced to import the DNS
158 name of the certificates if the provided names are NULL.
160 ** libgnutls: when receiving SNI names, only save and expose to application
161 the supported DNS names.
163 ** libgnutls: when importing the certificate names at the
164 gnutls_certificate_set* functions, only consider the CN as a fallback
165 if DNS names are provided via the alternative name extension.
167 ** ocsptool: use HTTP/1.0 for requests. This avoids issue with servers
168 serving chunk encoding which ocsptool doesn't support. Reported by Thomas
171 ** certtool: do not require a CA for OCSP signing tag. This follows the
172 recommendations in RFC6960 in 4.2.2.2 which allow a CA to delegate OCSP
173 signing to another certificate without requiring it to be a CA. Reported
176 ** gnutls-cli: on OCSP verification do not fail if we have a single valid
177 reply. Report and reproducer by Thomas Klute.
179 ** API and ABI modifications:
180 No changes since last version.
183 * Version 3.3.22 (released 2016-03-10)
185 ** libgnutls: Eliminated issues preventing buffers more than 2^32 bytes
186 to be used with hashing functions.
188 ** libgnutls: Follow closely RFC5280 recommendations and use UTCTime for
189 dates prior to 2050. Backported from 3.4.x branch.
191 ** libgnutls: Several fixes to prevent relying on undefined behavior of C
192 (found with libubsan).
194 ** libgnutls: SSL 3.0 is no longer included in the default priorities
195 list. It has to be explicitly enabled, e.g., with a string like
196 "NORMAL:+VERS-SSL3.0". The previous behavior can be restored using
197 the flag --with-ssl3 to configure.
199 ** API and ABI modifications:
200 No changes since last version.
203 * Version 3.3.21 (released 2016-02-03)
205 ** libgnutls: Corrected ALPN protocol negotiation. Before GnuTLS would negotiate
206 the last commonly supported protocol, rather than the first. Reported by
207 Remi Denis-Courmont (#63).
209 ** libgnutls: ARCFOUR (RC4) is no longer included in the default priorities
210 list. It has to be explicitly enabled, e.g., with a string like
211 "NORMAL:+ARCFOUR-128". The previous behavior can be restored using
212 the flag --with-arcfour128 to configure.
214 ** libgnutls: Corrected regression caused by incorrect fix in
215 gnutls_x509_ext_export_key_usage() at 3.3.20 release.
217 ** API and ABI modifications:
218 No changes since last version.
221 * Version 3.3.20 (released 2016-01-08)
223 ** libgnutls: Corrected memory leak in gnutls_pubkey_import_privkey() when
224 used with PKCS #11 keys.
226 ** libgnutls: For DSA and ECDSA keys in PKCS #11 objects, import
227 their public keys from either a public key object or a certificate.
228 That is, because private keys do not contain all the required
229 parameters for a direct import. Reported by Jan Vcelak.
231 ** libgnutls: Fixed issue when writing ECDSA private keys in PKCS #11
234 ** libgnutls: Fixed out-of-bounds read in gnutls_x509_ext_export_key_usage(),
235 report and patch by Tim Kosse.
237 ** libgnutls: Handle DNS name constraints with a leading dot. Backported
240 ** libgnutls: The max-record extension is no longer negotiated on DTLS. This resolves
241 issue with the max-record being negotiated but ignored.
243 ** API and ABI modifications:
244 No changes since last version.
247 * Version 3.3.19 (released 2015-11-22)
249 ** libgnutls: Properly require TLS 1.2 to all the CBC-SHA256 and CBC-SHA384
250 ciphersuites. This solves an interoperability issue with openssl.
251 Reported by Viktor Dukhovni.
253 ** libgnutls: Fixed memory leak in gnutls_pubkey_get_preferred_hash_algorithm(),
254 patch by Lennert Buytenhek.
256 ** libgnutls: When writing a certificate into a PKCS #11 token, ensure
257 that CKA_SERIAL_NUMBER and CKA_ISSUER are written.
259 ** libgnutls: Allow the presence of legacy ciphers and key exchanges in
260 priority strings and consider them a no-op.
262 ** libgnutls: On a rehandshake allow switching from anonymous to ECDHE and
265 ** libgnutls: Added GNUTLS_SKIP_GLOBAL_INIT macro to allow programs skipping
266 the implicit global initialization.
268 ** gnutls.pc: Don't include libtool specific options to link flags.
269 Reported by Dan Kegel.
271 ** API and ABI modifications:
272 GNUTLS_SKIP_GLOBAL_INIT: Added
275 * Version 3.3.18 (released 2015-09-12)
277 ** libgnutls: When re-importing CRLs to a trust list ensure that there
278 are no duplicate entries.
280 ** certtool: Removed any arbitrary limits imposed on input file sizes
281 and maximum number of certificates imported.
283 ** API and ABI modifications:
284 No changes since last version.
287 * Version 3.3.17 (released 2015-08-10)
289 ** libgnutls: Fix issue with server side sending the status request
290 extension even when not requested. Reported by Jeremy Harris.
292 ** libgnutls: gnutls_pkcs11_privkey_generate2() will store the generated
293 public key, unless the GNUTLS_PKCS11_OBJ_FLAG_NO_STORE_PUBKEY flag is
296 ** libgnutls: fixed double free in DN decoding [GNUTLS-SA-2015-3].
298 ** API and ABI modifications:
299 No changes since last version.
302 * Version 3.3.16 (released 2015-07-12)
304 ** libgnutls: Allow compilation with nettle 3.0 or later
306 ** libgnutls: corrected failure when importing plain files
307 with gnutls_x509_privkey_import2(), and a password was provided.
309 ** libgnutls: Don't reject certificates if a CA has the URI or IP address
310 name constraints, and the end certificate doesn't have an IP address
313 ** libgnutls: set and read the hint in DHE-PSK and ECDHE-PSK ciphersuites.
315 ** API and ABI modifications:
316 No changes since last version.
319 * Version 3.3.15 (released 2015-05-03)
321 ** libgnutls: gnutls_certificate_get_ours: will return the certificate even
322 if a callback was used to send it.
324 ** libgnutls: Fix for MD5 downgrade in TLS 1.2 signatures. Reported by
325 Karthikeyan Bhargavan [GNUTLS-SA-2015-2].
327 ** libgnutls: Check for invalid length in the X.509 version field. Without the check
328 certificates with invalid length would be detected as having an arbitrary
329 version. Reported by Hanno Böck.
331 ** API and ABI modifications:
332 No changes since last version.
335 * Version 3.3.14 (released 2015-03-30)
337 ** libgnutls: When retrieving OCTET STRINGS from PKCS #12 ContentInfo
338 structures use BER to decode them (requires libtasn1 4.3). That allows
339 to decode some more complex structures.
341 ** libgnutls: When an end-certificate with no name is present and there
342 are CA name constraints, don't reject the certificate. This follows RFC5280
343 advice closely. Reported by Fotis Loukos.
345 ** libgnutls: Fixed handling of supplemental data with types > 255.
346 Patch by Thierry Quemerais.
348 ** libgnutls: Fixed double free in the parsing of CRL distribution points certificate
349 extension. Reported by Robert Święcki.
351 ** libgnutls: Fixed a two-byte stack overflow in DTLS 0.9 protocol. That
352 protocol is not enabled by default (used by openconnect VPN).
354 ** libgnutls: The maximum user data send size is set to be the same for
355 block and non-block ciphersuites. This addresses a regression with wine:
356 https://bugs.winehq.org/show_bug.cgi?id=37500
358 ** libgnutls: When generating PKCS #11 keys, set CKA_ID, CKA_SIGN,
359 and CKA_DECRYPT when needed.
361 ** libgnutls: Allow names with zero size to be set using
362 gnutls_server_name_set(). That will disable the Server Name Indication.
363 Resolves issue with wine: https://gitlab.com/gnutls/gnutls/issues/2
365 ** API and ABI modifications:
366 No changes since last version.
369 * Version 3.3.13 (released 2015-02-25)
371 ** libgnutls: Enable AESNI in GCM on x86
373 ** libgnutls: Fixes in DTLS message handling
375 ** libgnutls: Check certificate algorithm consistency, i.e.,
376 check whether the signatureAlgorithm field matches the signature
377 field inside TBSCertificate.
379 ** gnutls-cli: Fixes in OCSP verification.
381 ** API and ABI modifications:
382 No changes since last version.
385 * Version 3.3.12 (released 2015-01-17)
387 ** libgnutls: When negotiating TLS use the lowest enabled version in
388 the client hello, rather than the lowest supported. In addition, do
389 not use SSL 3.0 as a version in the TLS record layer, unless SSL 3.0
390 is the only protocol supported. That addresses issues with servers that
391 immediately drop the connection when the encounter SSL 3.0 as the record
393 http://lists.gnutls.org/pipermail/gnutls-help/2014-November/003673.html
395 ** libgnutls: Corrected encoding and decoding of ANSI X9.62 parameters.
397 ** libgnutls: Handle zero length plaintext for VIA PadLock functions.
398 This solves a potential crash on AES encryption for small size plaintext.
399 Patch by Matthias-Christian Ott.
401 ** libgnutls: In DTLS don't combine multiple packets which exceed MTU.
402 Reported by Andreas Schultz. https://savannah.gnu.org/support/?108715
404 ** libgnutls: In DTLS decode all handshake packets present in a record
405 packet, in a single pass. Reported by Andreas Schultz.
406 https://savannah.gnu.org/support/?108712
408 ** libgnutls: When importing a CA file with a PKCS #11 URL, simply
409 import the certificates, if the URL specifies objects, rather than
410 treating it as trust module.
412 ** libgnutls: When importing a PKCS #11 URL and we know the type of
413 object we are importing, don't require the object type in the URL.
415 ** libgnutls: fixed openpgp authentication when gnutls_certificate_set_retrieve_function2
416 was used by the server.
418 ** guile: Fix compilation on MinGW. Previously only the static version of the
419 'guile-gnutls-v-2' library would be built, preventing dynamic loading from Guile.
421 ** guile: Fix harmless warning during compilation of gnutls.scm
422 Initially reported at <https://bugzilla.redhat.com/show_bug.cgi?id=1177847>.
424 ** certtool: --pubkey-info will also attempt to load a public key
427 ** gnutls-cli: Added --starttls-proto option. That allows to specify a
428 protocol for starttls negotiation.
430 ** API and ABI modifications:
431 No changes since last version.
434 * Version 3.3.11 (released 2014-12-11)
436 ** libgnutls: Corrected regression introduced in 3.3.9 related to
437 session renegotiation. Reported by Dan Winship.
439 ** libgnutls: Corrected parsing issue with OCSP responses.
441 ** API and ABI modifications:
442 No changes since last version.
445 * Version 3.3.10 (released 2014-11-10)
447 ** libgnutls: Refuse to import v1 or v2 certificates that contain
450 ** libgnutls: Fixes in usage of PKCS #11 token callback
452 ** libgnutls: Fixed bug in gnutls_x509_trust_list_get_issuer() when used
453 with a PKCS #11 trust module and without the GNUTLS_TL_GET_COPY flag.
454 Reported by David Woodhouse.
456 ** libgnutls: Removed superfluous random generator refresh on every call
457 of gnutls_deinit(). That reduces load and usage of /dev/urandom.
459 ** libgnutls: Corrected issue in export of ECC parameters to X9.63 format.
460 Reported by Sean Burford [GNUTLS-SA-2014-5].
462 ** libgnutls: When gnutls_global_init() is called for a second time, it
463 will check whether the /dev/urandom fd kept is still open and matches
464 the original one. That behavior works around issues with servers that
465 close all file descriptors.
467 ** libgnutls: Corrected behavior with PKCS #11 objects that are marked
468 as CKA_ALWAYS_AUTHENTICATE.
470 ** certtool: The default cipher for PKCS #12 structures is 3des-pkcs12.
471 That option is more compatible than AES or RC4.
473 ** API and ABI modifications:
474 No changes since last version.
477 * Version 3.3.9 (released 2014-10-13)
479 ** libgnutls: Fixes in the transparent import of PKCS #11 certificates.
480 Reported by Joseph Peruski.
482 ** libgnutls: Fixed issue with unexpected non-fatal errors resetting the
483 handshake's hash buffer, in applications using the heartbeat extension
484 or DTLS. Reported by Joeri de Ruiter.
486 ** libgnutls: When both a trust module and additional CAs are present
487 account the latter as well; reported by David Woodhouse.
489 ** libgnutls: added GNUTLS_TL_GET_COPY flag for
490 gnutls_x509_trust_list_get_issuer(). That allows the function to be used
491 in a thread safe way when PKCS #11 trust modules are in use.
493 ** libgnutls: fix issue in DTLS retransmission when session tickets
494 were in use; reported by Manuel Pégourié-Gonnard.
496 ** libgnutls-dane: Do not require the CA on a ca match to be direct CA.
498 ** libgnutls: Prevent abort() in library if getrusage() fails. Try to
499 detect instead which of RUSAGE_THREAD and RUSAGE_SELF would work.
501 ** guile: new 'set-session-server-name!' procedure; see the manual for
504 ** certtool: The authority key identifier will be set in a certificate only
505 if the CA's subject key identifier is set.
507 ** API and ABI modifications:
508 No changes since last version.
511 * Version 3.3.8 (released 2014-09-18)
513 ** libgnutls: Updates in the name constraints checks. No name constraints
514 will be checked for intermediate certificates. As our support for name
515 constraints is limited to e-mail addresses in DNS names, it is pointless
516 to check them on intermediate certificates.
518 ** libgnutls: Fixed issues in PKCS #11 object listing. Previously multiple
519 object listing would fail completely if a single object could not be exported.
521 ** libgnutls: Improved the performance of PKCS #11 object listing/retrieving,
522 by retrieving them in large batches. Report and suggestion by David
525 ** libgnutls: Fixed issue with certificates being sanitized by gnutls prior
526 to signature verification. That resulted to certain non-DER compliant modifications
527 of valid certificates, being corrected by libtasn1's parser and restructured as
528 the original. Issue found and reported by Antti Karjalainen and Matti Kamunen from
531 ** libgnutls: Fixes in gnutls_x509_crt_set_dn() and friends to properly handle
532 strings with embedded spaces and escaped commas.
534 ** libgnutls: when comparing a CA certificate with the trusted list compare
535 the name and key only instead of the whole certificate. That is to handle
536 cases where a CA certificate was superceded by a different one with the same
537 name and the same key.
539 ** libgnutls: when verifying a certificate against a p11-kit trusted
540 module, use the attached extensions in the module to override the CA's
541 extensions (that requires p11-kit 0.20.7).
543 ** libgnutls: In DTLS prevent sending zero-size fragments in certain cases
544 of MTU split. Reported by Manuel Pégourié-Gonnard.
546 ** libgnutls: Added gnutls_x509_trust_list_verify_crt2() which allows
547 verifying using a hostname and a purpose (extended key usage). That
548 enhances PKCS #11 trust module verification, as it can now check the purpose
549 when this function is used.
551 ** libgnutls: Corrected gnutls_x509_crl_verify() which would always report
552 a CRL signature as invalid. Reported by Armin Burgmeier.
554 ** libgnutls: added option --disable-padlock to allow disabling the padlock
557 ** p11tool: when listing tokens, list their type as well.
559 ** p11tool: when listing objects from a trust module print any attached
560 extensions on certificates.
562 ** API and ABI modifications:
563 gnutls_x509_crq_get_extension_by_oid2: Added
564 gnutls_x509_crt_get_extension_by_oid2: Added
565 gnutls_x509_trust_list_verify_crt2: Added
566 gnutls_x509_ext_print: Added
567 gnutls_x509_ext_deinit: Added
568 gnutls_x509_othername_to_virtual: Added
569 gnutls_pkcs11_obj_get_exts: Added
572 * Version 3.3.7 (released 2014-08-24)
574 ** libgnutls: Added function to export the public key of a PKCS #11
575 private key. Contributed by Wolfgang Meyer zu Bergsten.
577 ** libgnutls: Explicitly set the exponent in PKCS #11 key generation.
578 That improves compatibility with certain PKCS #11 modules. Contributed by
579 Wolfgang Meyer zu Bergsten.
581 ** libgnutls: When generating a PKCS #11 private key allow setting
582 the WRAP/UNWRAP flags. Contributed by Wolfgang Meyer zu Bergsten.
584 ** libgnutls: gnutls_pkcs11_privkey_t will always hold an open session
587 ** libgnutls: bundle replacements of inet_pton and inet_aton if not
590 ** libgnutls: initialize parameters variable on PKCS #8 decryption.
592 ** libgnutls: gnutls_pkcs12_verify_mac() will not fail in other than SHA1
595 ** libgnutls: gnutls_x509_crt_check_hostname() will follow the RFC6125
596 requirement of checking the Common Name (CN) part of DN only if there is
597 a single CN present in the certificate.
599 ** libgnutls: The environment variable GNUTLS_FORCE_FIPS_MODE can be used
600 to force the FIPS mode, when set to 1.
602 ** libgnutls: In DTLS ignore only errors that relate to unexpected packets
603 and decryption failures.
605 ** p11tool: Added --info parameter.
607 ** certtool: Added --mark-wrap parameter.
609 ** danetool: --check will attempt to retrieve the server's certificate
610 chain and verify against it.
612 ** danetool/gnutls-cli-debug: Added --app-proto parameters which can
613 be used to enforce starttls (currently only SMTP and IMAP) on the connection.
615 ** danetool: Added openssl linking exception, to allow linking
618 ** API and ABI modifications:
619 GNUTLS_PKCS11_OBJ_ATTR_MATCH: Added
620 gnutls_pkcs11_privkey_export_pubkey: Added
621 gnutls_pkcs11_obj_flags_get_str: Added
622 gnutls_pkcs11_obj_get_flags: Added
625 * Version 3.3.6 (released 2014-07-23)
627 ** libgnutls: Use inet_ntop to print IP addresses when available
629 ** libgnutls: gnutls_x509_crt_check_hostname and friends will also check
630 IP addresses, and match documented behavior. Reported by David Woodhouse.
632 ** libgnutls: DSA key generation in FIPS140-2 mode doesn't allow 1024
635 ** libgnutls: fixed issue in gnutls_pkcs11_reinit() which prevented tokens
636 being usable after a reinitialization.
638 ** libgnutls: fixed PKCS #11 private key operations after a fork.
640 ** libgnutls: fixed PKCS #11 ECDSA key generation.
642 ** libgnutls: The GNUTLS_CPUID_OVERRIDE environment variable can be used to
643 explicitly enable/disable the use of certain CPU capabilities. Note that CPU
644 detection cannot be overriden, i.e., VIA options cannot be enabled on an Intel
645 CPU. The currently available options are:
646 0x1: Disable all run-time detected optimizations
650 0x100000: Enable VIA padlock
651 0x200000: Enable VIA PHE
652 0x400000: Enable VIA PHE SHA512
654 ** libdane: added dane_query_to_raw_tlsa(); patch by Simon Arlott.
656 ** p11tool: use GNUTLS_SO_PIN to read the security officer's PIN if set.
658 ** p11tool: ask for label when one isn't provided.
660 ** p11tool: added --batch parameter to disable any interactivity.
662 ** p11tool: will not implicitly enable so-login for certain types of
663 objects. That avoids issues with tokens that require different login
666 ** certtool/p11tool: Added the --curve parameter which allows to explicitly
667 specify the curve to use.
669 ** API and ABI modifications:
670 gnutls_certificate_set_x509_trust_dir: Added
671 gnutls_x509_trust_list_add_trust_dir: Added
674 * Version 3.3.5 (released 2014-06-26)
676 ** libgnutls: Added gnutls_record_recv_packet() and gnutls_packet_deinit().
677 These functions provide a variant of gnutls_record_recv() that avoids
678 the final memcpy of data.
680 ** libgnutls: gnutls_x509_crl_iter_crt_serial() was added as a
681 faster variant of gnutls_x509_crl_get_crt_serial() when coping with
682 very large structures.
684 ** libgnutls: When the decoding of a printable DN element fails, then treat
685 it as unknown and print its hex value rather than failing. That works around
686 an issue in a TURKTRST root certificate which improperly encodes the
687 X520countryName element.
689 ** libgnutls: gnutls_x509_trust_list_add_trust_file() will return the number
690 of certificates present in a PKCS #11 token when loading it.
692 ** libgnutls: Allow the post client hello callback to put the handshake on
693 hold, by returning GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED.
695 ** certtool: option --to-p12 will now consider --load-ca-certificate
697 ** certtol: Added option to specify the PKCS #12 friendly name on command
700 ** p11tool: Allow marking a certificate copied to a token as a CA.
702 ** API and ABI modifications:
703 GNUTLS_PKCS11_OBJ_FLAG_MARK_CA: Added
704 gnutls_x509_crl_iter_deinit: Added
705 gnutls_x509_crl_iter_crt_serial: Added
706 gnutls_record_recv_packet: Added
707 gnutls_packet_deinit: Added
708 gnutls_packet_get: Added
711 * Version 3.3.4 (released 2014-05-31)
713 ** libgnutls: Updated Andy Polyakov's assembly code. That prevents a
714 crash on certain CPUs.
716 ** API and ABI modifications:
717 No changes since last version.
720 * Version 3.3.3 (released 2014-05-30)
722 ** libgnutls: Eliminated memory corruption issue in Server Hello parsing.
723 Issue reported by Joonas Kuorilehto of Codenomicon.
725 ** libgnutls: gnutls_global_set_mutex() was modified to operate with the
726 new initialization process.
728 ** libgnutls: Increased the maximum certificate size buffer
729 in the PKCS #11 subsystem.
731 ** libgnutls: Check the return code of getpwuid_r() instead of relying
732 on the result value. That avoids issue in certain systems, when using
733 tofu authentication and the home path cannot be determined. Issue reported
736 ** libgnutls-dane: Improved dane_verify_session_crt(), which now attempts to
737 create a full chain. This addresses points from https://savannah.gnu.org/support/index.php?108552
739 ** gnutls-cli: --dane will only check the end certificate if PKIX validation
742 ** gnutls-cli: --benchmark-soft-ciphers has been removed. That option cannot
743 be emulated with the implicit initialization of gnutls.
745 ** certtool: Allow multiple organizations and organizational unit names to
746 be specified in a template.
748 ** certtool: Warn when invalid configuration options are set to a template.
750 ** ocsptool: Include path in ocsp request. This resolves #108582
751 (https://savannah.gnu.org/support/?108582), reported by Matt McCutchen.
753 ** API and ABI modifications:
754 gnutls_credentials_get: Added
757 * Version 3.3.2 (released 2014-05-06)
759 ** libgnutls: Added the 'very weak' certificate verification profile
760 that corresponds to 64-bit security level.
762 ** libgnutls: Corrected file descriptor leak on random generator
765 ** libgnutls: Corrected file descriptor leak on PSK password file
766 reading. Issue identified using the Codenomicon TLS test suite.
768 ** libgnutls: Avoid deinitialization if initialization has failed.
770 ** libgnutls: null-terminate othername alternative names.
772 ** libgnutls: gnutls_x509_trust_list_get_issuer() will operate correctly
773 on a PKCS #11 trust list.
775 ** libgnutls: Several small bug fixes identified using valgrind and
776 the Codenomicon TLS test suite.
778 ** libgnutls-dane: Accept a certificate using DANE if there is at least one
779 entry that matches the certificate. Patch by simon [at] arlott.org.
781 ** libgnutls-guile: Fixed compilation issue.
783 ** certtool: Allow exporting a CRL on DER format.
785 ** certtool: The ECDSA keys generated by default use the SECP256R1 curve
786 which is supported more widely than the previously used SECP224R1.
788 ** API and ABI modifications:
789 GNUTLS_PROFILE_VERY_WEAK: Added
792 * Version 3.3.1 (released 2014-04-19)
794 ** libgnutls: Enforce more strict checks to heartbeat messages
795 concerning padding and payload. Suggested by Peter Dettman.
797 ** libgnutls: Allow decoding PKCS #8 files with ECC parameters
800 ** libgnutls: Several small bug fixes found by coverity.
802 ** libgnutls: The conditionally available self-test functions
803 were moved to self-test.h.
805 ** libgnutls: Fixed issue with the check of incoming data when two
806 different recv and send pointers have been specified. Reported and
807 investigated by JMRecio.
809 ** libgnutls: Fixed issue in the RSA-PSK key exchange, which would
810 result to illegal memory access if a server hint was provided. Reported
813 ** libgnutls: Fixed client memory leak in the PSK key exchange, if a
814 server hint was provided.
816 ** libgnutls: Corrected the *get_*_othername_oid() functions.
818 ** API and ABI modifications:
819 No changes since last version.
822 * Version 3.3.0 (released 2014-04-10)
824 ** libgnutls: The initialization of the library was moved to a
825 constructor. That is, gnutls_global_init() is no longer required
826 unless linking with a static library or a system that does not
827 support library constructors.
829 ** libgnutls: static libraries are not built by default.
831 ** libgnutls: PKCS #11 initialization is delayed to first usage.
832 That avoids long delays in gnutls initialization due to broken PKCS #11
835 ** libgnutls: The PKCS #11 subsystem is re-initialized "automatically"
836 on the first PKCS #11 API call after a fork.
838 ** libgnutls: certificate verification profiles were introduced
839 that can be specified as flags to verification functions. They
840 are enumerations in gnutls_certificate_verification_profiles_t
841 and can be converted to flags for use in a verification function
842 using GNUTLS_PROFILE_TO_VFLAGS().
844 ** libgnutls: Added the ability to read system-specific initial
845 keywords, if they are prefixed with '@'. That allows a compile-time
846 specified configuration file to be used to read pre-configured priority
847 strings from. That can be used to impose system specific policies.
849 ** libgnutls: Increased the default security level of priority
850 strings (NORMAL and PFS strings require at minimum a 1008 DH prime),
851 and set a verification profile by default. The LEGACY keyword is
852 introduced to set the old defaults.
854 ** libgnutls: Added support for the name constraints PKIX extension.
855 Currently only DNS names and e-mails are supported (no URIs, IPs
858 ** libgnutls: Security parameter SEC_PARAM_NORMAL was renamed to
859 SEC_PARAM_MEDIUM to avoid confusion with the priority string NORMAL.
861 ** libgnutls: Added new API in x509-ext.h to handle X.509 extensions.
862 This API handles the X.509 extensions in isolation, allowing to parse
863 similarly formatted extensions stored in other structures.
865 ** libgnutls: When generating DSA keys the macro GNUTLS_SUBGROUP_TO_BITS
866 can be used to specify a particular subgroup as the number of bits in
867 gnutls_privkey_generate; e.g., GNUTLS_SUBGROUP_TO_BITS(2048, 256).
869 ** libgnutls: DH parameter generation is now delegated to nettle.
870 That unfortunately has the side-effect that DH parameters longer than
871 3072 bits, cannot be generated (not without a nettle update).
873 ** libgnutls: Separated nonce RNG from the main RNG. The nonce
874 random number generator is based on salsa20/12.
876 ** libgnutls: The buffer alignment provided to crypto backend is
877 enforced to be 16-byte aligned, when compiled with cryptodev
878 support. That allows certain cryptodev drivers to operate more
881 ** libgnutls: Return error when a public/private key pair that doesn't
882 match is set into a credentials structure.
884 ** libgnutls: Depend on p11-kit 0.20.0 or later.
886 ** libgnutls: The new padding (%NEW_PADDING) experimental TLS extension has
887 been removed. It was not approved by IETF.
889 ** libgnutls: The experimental xssl library is removed from the gnutls
892 ** libgnutls: Reduced the number of gnulib modules used in the main library.
894 ** libgnutls: Added priority string %DISABLE_WILDCARDS.
896 ** libgnutls: Added the more extensible verification function
897 gnutls_certificate_verify_peers(), that allows checking, in addition
898 to a peer's DNS hostname, for the key purpose of the end certificate
899 (via PKIX extended key usage).
901 ** certtool: Timestamps for serial numbers were increased to 8 bytes,
902 and in batch mode to 12 (appended with 4 random bytes).
904 ** certtool: When no CRL number is provided (or value set to -1), then
905 a time-based number will be used, similarly to the serial generation
906 number in certificates.
908 ** certtool: Print the SHA256 fingerprint of a certificate in addition
911 ** libgnutls: Added --enable-fips140-mode configuration option (unsupported).
912 That option enables (when running on FIPS140-enabled system):
913 o RSA, DSA and DH key generation as in FIPS-186-4 (using provable primes)
914 o The DRBG-CTR-AES256 deterministic random generator from SP800-90A.
915 o Self-tests on initialization on ciphers/MACs, public key algorithms
916 and the random generator.
917 o HMAC-SHA256 verification of the library on load.
918 o MD5 is included for TLS purposes but cannot be used by the high level
920 o All ciphers except AES are disabled.
921 o All MACs and hashes except GCM and SHA are disabled (e.g., HMAC-MD5).
922 o All keys (temporal and long term) are zeroized after use.
923 o Security levels are adjusted to the FIPS140-2 recommendations (rather

1180 ** libgnutls: Added support for DTLS 1.2.
1182 ** libgnutls: Added support for the Application Layer Protocol Negotiation
1185 ** libgnutls: Removed support for the RSA-EXPORT ciphersuites.

1198 ** certtool: When generating PKCS #12 files use by default the
1199 ARCFOUR (RC4) cipher to be compatible with devices that don't
1200 support AES with PKCS #12.
1202 ** libgnutls: Load CA certificates in android 4.x systems.
1204 ** libgnutls: Optimized CA certificate loading.
1206 ** libgnutls: Private keys are overwritten on deinitialization.

1250 still available (inserted).
1252 ** libgnutls: Try to detect fork even during nonce generation.
1254 ** API and ABI modifications:
1255 gnutls_handshake_set_random: Added
1256 gnutls_transport_set_int2: Added
1257 gnutls_transport_get_int2: Added
1258 gnutls_transport_get_int: Added
1259 gnutls_record_cork: Exported
1260 gnutls_record_uncork: Exported
1261 gnutls_pkcs11_privkey_status: Added
1264 * Version 3.1.8 (released 2013-02-10)
1266 ** libgnutls: Fixed issue in gnutls_x509_privkey_import2() which didn't return
1267 GNUTLS_E_DECRYPTION_FAILED in all cases, and affect certtool operation
1268 with encrypted keys. Reported by Yan Fiz.
1270 ** libgnutls: The minimum DH bits accepted by priorities NORMAL and
1271 PERFORMANCE was set to previous defaults 727 bits. Reported by Diego
1274 ** libgnutls: Corrected issue which prevented gnutls_pubkey_verify_hash()
1275 to operate with long keys. Reported by Erik A Jensen.
1277 ** API and ABI modifications:
1278 No changes since last version.
1281 * Version 3.1.7 (released 2013-02-04)
1283 ** certtool: Added option "dn" which allows to directly set the DN
1284 in a template from an RFC4514 string.
1286 ** danetool: Added options: --dlv and --insecure. Suggested by Paul Wouters.
1288 ** libgnutls-xssl: Added a new library to simplify GnuTLS usage.
1290 ** libgnutls-dane: Added function to specify a DLV file.
1292 ** libgnutls: Heartbeat code was made optional.
1294 ** libgnutls: Fixes in server side of DTLS-0.9.
1296 ** libgnutls: DN variable 'T' was expanded to 'title'.
1298 ** libgnutls: Fixes in record padding parsing to prevent a timing attack.
1299 Issue reported by Kenny Paterson and Nadhem Alfardan.
1301 ** libgnutls: Added functions to directly set the DN in a certificate
1302 or request from an RFC4514 string.
1304 ** libgnutls: Optimizations in the random generator. The re-seeding of
1305 it is now explicitly done on every session deinit.
1307 ** libgnutls: Simplified the DTLS sliding window implementation.
1309 ** libgnutls: The minimum DH bits accepted by a client are now set
1310 by the specified priority string. The current values correspond to the
1311 previous defaults (727 bits), except for the SECURE128 and SECURE192
1312 strings which increase the minimum to 1248 and 1776 respectively.
1314 ** libgnutls: Added the gnutls_record_cork() and uncork API to enable
1315 buffering in sending application data.
1317 ** libgnutls: Removed default random padding, and added a length-hiding interface
1318 instead. Both the server and the client must support this extension. Whether
1319 length-hiding can be used on a given session can be checked using
1320 gnutls_record_can_use_length_hiding(). Contributed by Alfredo Pironti.
1322 ** libgnutls: Added the experimental %NEW_PADDING priority string. It enables
1323 a new padding mechanism in TLS allowing arbitrary padding in TLS records
1324 in all ciphersuites, which makes length-hiding more efficient and solves
1325 the issues with timing attacks on CBC ciphersuites.
1327 ** libgnutls: Corrected gnutls_cipher_decrypt2() when used with AEAD
1328 ciphers (i.e., AES-GCM). Reported by William McGovern.

1370 ** libgnutls: Ignore heartbeat messages when received out-of-order,
1371 instead of issuing an error.
1373 ** libgnutls: Stricter RSA PKCS #1 1.5 encoding and decoding. Reported
1376 ** libgnutls: TPM support is disabled by default because GPL programs
1377 cannot link with it. Use --with-tpm to enable it.
1379 ** libgnutls-guile: Fixed parallel compilation issue.
1381 ** gnutls-cli: It will try to connect to all possible returned addresses
1384 ** API and ABI modifications:
1385 No changes since last version.

1390 ** libgnutls: Added functions to parse the certificates policies
1393 ** libgnutls: Handle BMPString (UCS-2) encoding in the Distinguished
1394 Name by translating it to UTF-8 (works on windows or systems with iconv).
1396 ** libgnutls: Added PKCS #11 key generation function that returns the
1397 public key on generation.
1399 ** libgnutls: Corrected bug in priority string parsing, that mostly
1400 affected combined levels. Patch by Tim Kosse.
1402 ** certtool: The --pubkey-info option can be combined with the
1403 --load-privkey or --load-request to print the corresponding public keys.
1405 ** certtool: It is able to set certificate policies via a template.
1407 ** certtool: Added --hex-numbers option which prints big numbers in
1408 an easier to parse format.
1410 ** p11tool: After key generation, outputs the public key (useful in
1411 tokens that do not store the public key).
1413 ** danetool: It is being built even without libgnutls-dane (the
1414 --check functionality is disabled though).
1416 ** API and ABI modifications:
1417 gnutls_pkcs11_privkey_generate2: Added

1448 ** libgnutls: Added verification flag GNUTLS_VERIFY_DO_NOT_ALLOW_UNSORTED_CHAIN
1449 and made GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN the default.
1451 ** libgnutls: Always tolerate key usage violation errors from the side
1452 of the peer, but also notify via an audit message.
1454 ** gnutls-cli: Added --local-dns option.
1456 ** danetool: Corrected bug that prevented loading PEM files.
1458 ** danetool: Added --check option to allow querying and verifying

1505 ** libgnutls: Added functions to export structures in an allocated buffer.
1507 ** libgnutls: Added gnutls_ocsp_resp_check_crt() to check whether the OCSP
1508 response corresponds to the given certificate.
1510 ** libgnutls: In client side gnutls_init() enables the session ticket and
1511 OCSP certificate status request extensions by default. The flag
1512 GNUTLS_NO_EXTENSIONS can be used to prevent that.
1514 ** libgnutls: Several updates in the OpenPGP code. The generating code
1515 is fully RFC6091 compliant and RFC5081 support is only supported in client
1518 ** libgnutls-dane: Added. It is a library to provide DANE with DNSSEC
1519 certificate verification.
1521 ** gnutls-cli: Added --dane option to enable DANE certificate verification.
1523 ** danetool: Added tool to generate DANE TLSA Resource Records (RR).

1561 ** libgnutls: Fixed bug in gnutls_x509_trust_list_add_system_trust()
1562 and gnutls_x509_trust_list_add_trust_mem() that prevented the loading
1563 of certificates in the windows platform.
1565 ** libgnutls: Corrected bug in OpenPGP subpacket encoding.
1567 ** libgnutls: Added support for DTLS/TLS heartbeats by Olga Smolenchuk.
1568 (the work was done during Google Summer of Code).
1570 ** libgnutls: Added X.509 certificate verification flag
1571 GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN. This flag allows the verification
1572 of unsorted certificate chains and is enabled by default for
1573 TLS certificate verification (if gnutls_certificate_set_verify_flags()
1574 does not override it).
1576 ** libgnutls: Prints warning on certificates that contain keys of
1577 an insecure level. If the %COMPAT priority flag is not specified
1578 the TLS connection fails.
1580 ** libgnutls: Correctly restore gnutls_record_recv() in DTLS mode
1581 if interrupted during the retrasmition of handshake data.
1583 ** libgnutls: Better mingw32 support (patch by LRN).

1586 key usage violation errors (they are far too common to ignore).
1588 ** libgnutls: Added GNUTLS_STATELESS_COMPRESSION flag to gnutls_init(),
1589 which provides a tool to counter compression-related attacks where
1590 parts of the data are controlled by the attacker _and_ are placed in
1591 separate records (use with care - do not use compression if not sure).
1593 ** libgnutls: Depends on libtasn1 2.14 or later.
1595 ** certtool: Prints the number of bits of the public key algorithm
1596 parameter in a private key.
1598 ** API and ABI modifications:
1599 gnutls_x509_privkey_get_pk_algorithm2: Added
1600 gnutls_heartbeat_ping: Added
1601 gnutls_heartbeat_pong: Added

1605 gnutls_heartbeat_get_timeout: Added
1606 GNUTLS_SEC_PARAM_WEAK: Added
1607 GNUTLS_SEC_PARAM_INSECURE: Added
1609 * Version 3.1.1 (released 2012-09-02)
1611 ** gnutls-serv: Listens on IPv6. Patch by Bernhard R. Link.
1613 ** certtool: Changes in password handling of certtool.
1614 Ask password when required and only if the '--password' option is not
1615 given. If the '--password' option is given during key generation then
1616 assume the PKCS #8 file format, instead of ignoring the password.
1618 ** tpmtool: No longer asks for key password in registered keys.
1620 ** libgnutls: Elliptic curve code was optimized by Ilya Tumaykin.
1621 wmNAF is now used for point multiplication and other optimizations.
1622 (the major part of the work was done during Google Summer of Code).
1624 ** libgnutls: The default pull_timeout_function only uses select
1625 instead of a combination of select() and recv() to prevent issues
1626 when used in stream sockets in some systems.
1628 ** libgnutls: Be tolerant in ECDSA signature violations (e.g. using
1629 SHA256 with a SECP384 curve instead of SHA-384), to interoperate with
1632 ** libgnutls: Fixed DSA and ECDSA signature generation in smart
1633 cards. Thanks to Andreas Schwier from cardcontact.de for providing
1634 me with ECDSA capable smart cards.
1636 ** API and ABI modifications:
1637 gnutls_sign_algorithm_get: Added
1638 gnutls_sign_get_hash_algorithm: Added
1639 gnutls_sign_get_pk_algorithm: Added
1642 * Version 3.1.0 (released 2012-08-15)
1644 ** libgnutls: Added direct support for TPM as a cryptographic module
1645 in gnutls/tpm.h. TPM keys can be used in functions accepting files
1646 using URLs of the following types:
1647 tpmkey:file=/path/to/file
1648 tpmkey:uuid=7f468c16-cb7f-11e1-824d-b3a4f4b20343;storage=user
1650 ** libgnutls: Priority string level keywords can be combined.
1651 For example the string "SECURE256:+SUITEB128" is now allowed.
1653 ** libgnutls: requires libnettle 2.5.
1655 ** libgnutls: Use the PKCS #1 1.5 encoding provided by nettle (2.5)
1656 for encryption and signatures.
1658 ** libgnutls: Added GNUTLS_CERT_SIGNATURE_FAILURE to differentiate between
1659 generic errors and signature verification errors in the verification
1662 ** libgnutls: Added gnutls_pkcs12_simple_parse() as a helper function
1663 to simplify parsing in most PKCS #12 use cases.
1665 ** libgnutls: gnutls_certificate_set_x509_simple_pkcs12_file() adds
1666 the whole certificate chain (if any) to the credentials structure, instead
1667 of only the end-user certificate.
1669 ** libgnutls: Key import functions such as gnutls_pkcs12_simple_parse()
1670 and gnutls_x509_privkey_import_pkcs8(), return consistently
1671 GNUTLS_E_DECRYPTION_FAILED if the input structure is encrypted but no
1672 password was provided.
1674 ** libgnutls: Added gnutls_handshake_set_timeout() a function that
1675 allows to set the maximum time spent in a handshake.
1677 ** libgnutlsxx: Added session::set_transport_vec_push_function. Patch
1680 ** tpmtool: Added. It is a tool to generate private keys in the
1683 ** gnutls-cli: --benchmark-tls was split to --benchmark-tls-kx
1684 and --benchmark-tls-ciphers
1686 ** certtool: generated PKCS #12 structures may hold more than one
1687 private key. Patch by Lucas Fisher.
1689 ** certtool: Added option --null-password to generate/decrypt keys
1690 that use a NULL password (in schemas that distinguish between NULL
1691 an empty passwords).
1693 ** minitasn1: Upgraded to libtasn1 version 2.13.

2132 ** libgnutls: Added new priority string %SERVER_PRECEDENCE, which
2133 changes the ciphersuite selection procedure. If specified the server
2134 priorities will be used for selection instead of the client's.
2136 ** libgnutls: Optimizations in Diffie-Hellman parameters generation
2139 ** libgnutls: When session tickets are negotiated and used in a

2144 ** libgnutls: Added gnutls_priority_get_cipher_suite_index() to
2145 allow listing the ciphersuites enabled in a priority structure.
2146 It outputs an index to be used in gnutls_get_cipher_suite_info().
2148 ** libgnutls: Optimizations in the elliptic curve code --timing
2149 attacks resistant code is only used in ECDSA private key operations.

2172 The reason was that the code that auto-generated the man pages missed
2173 many APIs and we couldn't fix it (volunteers welcome). See the info
2174 manual or the GTK-DOC manual instead.
2176 ** API and ABI modifications:

2811 ** libgnutls: Record version of Client Hellos is now set by default to
2812 SSL 3.0. To restore the previous default behavior use %LATEST_RECORD_VERSION
2815 ** libgnutls: Use ASN1_NULL when writing parameters for RSA signatures.
2816 This makes us comply with RFC3279. Reported by Michael Rommel.
2818 ** gnutls-serv: Corrected a buffer overflow. Reported and patch by Tomas Mraz.
2820 ** API and ABI modifications:
2821 No changes since last version.
2823 * Version 2.11.5 (released 2010-12-01)
2825 ** libgnutls: Reverted default behavior for verification and
2826 introduced GNUTLS_VERIFY_DO_NOT_ALLOW_X509_V1_CA_CRT. Thus by default
2827 V1 trusted CAs are allowed, unless the new flag is specified.
2829 ** libgnutls: Correctly add leading zero to PKCS #8 encoded DSA key.
2830 Reported by Jeffrey Walton.
2832 ** libgnutls: Added SIGN-ALL, CTYPE-ALL, COMP-ALL, and VERS-TLS-ALL
2833 as priority strings. Those allow to set all the supported algorithms
2836 ** p11tool: Introduced. It allows manipulating pkcs 11 tokens.
2838 ** gnutls-cli: Print channel binding only in verbose mode.
2839 Before it printed it after the 'Compression:' output, thus breaking
2840 Emacs starttls.el string searches.
2842 ** API and ABI modifications:
2843 gnutls_pkcs11_token_init: New function
2844 gnutls_pkcs11_token_set_pin: New function
2846 * Version 2.11.4 (released 2010-10-15)
2848 ** libgnutls: Add new API gnutls_session_channel_binding.
2849 The function is used to get the channel binding data. Currently only
2850 the "tls-unique" (RFC 5929) channel binding type is supported, through
2851 the GNUTLS_CB_TLS_UNIQUE type. See new section "Channel Bindings" in
2854 ** gnutls-cli, gnutls-serv: Print 'tls-unique' Channel Bindings.
2856 ** doc: Added pkcs11.h header file to GTK-DOC manual.
2858 ** build: Update gnulib files.
2860 ** i18n: Update translations.
2862 ** tests: Add self tests gendh.c. Speed up Guile self checks.
2864 ** API and ABI modifications:
2865 gnutls_session_channel_binding: New function.
2866 gnutls_channel_binding_t: New enumeration.
2867 GNUTLS_CB_TLS_UNIQUE: New gnutls_channel_binding_t enum member.
2868 GNUTLS_E_CHANNEL_BINDING_NOT_AVAILABLE: New error code.
2870 * Version 2.11.3 (released 2010-10-14)
2872 ** Indent code to follow the GNU Coding Standard.
2873 You should be able to unpack the 2.11.2 release and run 'make indent'
2874 twice to get exactly the same content as 2.11.3 except for generated
2875 files. Using GNU Indent 2.2.11.
2877 ** API and ABI modifications:
2878 No changes since last version.
2880 * Version 2.11.2 (released 2010-10-08)
2882 ** libgnutls: Several bug fixes on session resumption
2883 and session tickets support.
2885 ** libgnutls: Add new extended key usage ipsecIKE.
2887 ** certtool: Renamed PKCS #11 options to: --p11-provider,
2888 --p11-export-url, --p11-list-certs, --p11-list-certs,
2889 --p11-list-privkeys, --p11-list-trusted, --p11-list-all-certs,
2890 --p11-list-all, --p11-list-tokens, --p11-login, --p11-write,
2891 --p11-write-label, --p11-write-trusted, --p11-detailed-url,
2894 ** libgnutls: Corrected bug that caused importing DSA keys as RSA,
2895 introduced with the new nettle code.
2897 ** libgnutls: Corrected advertizing issue for session tickets.
2899 ** API and ABI modifications:
2900 gnutls_x509_crt_get_subject_unique_id: ADDED.
2901 gnutls_x509_crt_get_issuer_unique_id: ADDED.
2903 * Version 2.11.1 (released 2010-09-14)
2905 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
2906 to use the libgcrypt back end.
2908 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
2909 backend crypto library.
2911 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
2913 ** libgnutls: Several updates in the buffering internal interface.
2915 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
2916 tabs are being skipped.
2918 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
2920 ** libgnutls: The %COMPAT flag now allows larger records that violate the
2923 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
2924 system calls. Applications that depended on it being 1 should explicitly call
2925 gnutls_transport_set_lowat().
2927 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
2928 to ECRYPT II recommendations. Mappings were moved to a single location
2929 and DSA keys are handled differently (since DSA2 allows for 1024,2048
2930 and 3072 keys only).
2932 ** libgnutls: gnutls_x509_privkey_import() will fallback to
2933 gnutls_x509_privkey_import_pkcs8() without a password, if it
2934 is unable to decode the key.
2936 ** libgnutls: HMAC-MD5 no longer used by default.
2938 ** API and ABI modifications:
2939 gnutls_openpgp_privkey_sec_param: ADDED
2940 gnutls_x509_privkey_sec_param: ADDED
2942 * Version 2.11.0 (released 2010-07-22)
2944 ** libgnutls: support scattered write using writev(). This takes
2945 advantage of the new buffering layer and allows queuing of packets
2946 and flushing them. This is currently used for handshake messages
2949 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
2950 alternative locking procedures. By default the system available
2951 locking is used. In *NIX pthreads are used and in windows the
2952 critical section API. This follows a different approach than the
2953 previous versions that depended on libgcrypt initialization. The
2954 locks are now set by default in systems that support it. Programs
2955 that used gcry_control() to set thread locks should insert it into
2957 #if GNUTLS_VERSION_NUMBER <= 0x020b00
2961 ** libgnutls: Added support for reading DN from EV-certificates.
2963 jurisdictionOfIncorporationLocalityName,
2964 jurisdictionOfIncorporationStateOrProvinceName,
2965 jurisdictionOfIncorporationCountryName
2967 ** libgnutls: Added support for DSA signing/verifying with bit
2970 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
2971 has to be called to register any required md5 handlers.
2973 ** libgnutls: Internal buffering code was replaced by simpler
2974 code contributed by Jonathan Bastien-Filiatrault.
2976 ** libgnutls: Internal API for extensions augmented to allow
2977 safe storing and loading of data on resumption. This allows writing
2978 self-contained extensions (when possible). As a side effect
2979 the OPRFI extension was removed.
2981 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
2983 ** libgnutls: Added PKCS #11 support and an API to access objects in
2984 gnutls/pkcs11.h. Currently certificates and public keys can be
2985 imported from tokens, and operations can be performed on private keys.
2987 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
2989 ** libgnutls: Added initial support for the nettle library. It uses
2990 the system's random generator for seeding. That is /dev/urandom in Linux,
2991 system calls in Win32 and EGD on other systems.
2993 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
2994 works even when resuming a session.
2996 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
2997 similar gnutls_certificate_set_server_retrieve_function() and
2998 gnutls_certificate_set_client_retrieve_function(). In addition it support
2999 PKCS #11 private keys.
3001 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
3002 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
3004 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
3005 sizes for private keys using a human understandable scale.
3007 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
3008 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
3009 --pkcs11-delete-url, --pkcs11-write
3011 certtool: The --pkcs-cipher is taken into account when generating a
3012 private key. The default cipher used now is aes-128. The old behavior can
3013 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
3015 certtool: Added --certificate-pubkey to print the public key of the
3018 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
3019 can now accept a PKCS #11 URL in addition to a file. This will allow for
3020 example to use the Gnome-keyring trusted certificate list to verify
3021 connections using a url such as:
3022 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

3103 * Version 2.10.1 (released 2010-07-25)
3105 ** libgnutls: Added support for broken certificates that indicate RSA
3108 ** gnutls-cli: Allow verification using V1 CAs.
3110 ** libgnutls: gnutls_x509_privkey_import() will fallback to
3111 gnutls_x509_privkey_import_pkcs8() without a password, if it
3112 is unable to decode the key.
3114 ** libgnutls: Correctly deinitialize crypto API functions to prevent
3115 a memory leak. Reported by Mads Kiilerich.
3117 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
3118 issue a warning, that the output key might not be working everywhere.
3120 ** certtool: The --pkcs-cipher is taken into account when generating a
3121 private key. The default cipher used now is aes-128. The old behavior
3122 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
3124 ** API and ABI modifications:
3125 No changes since last version.
3127 * Version 2.10.0 (released 2010-06-25)
3129 ** API and ABI modifications:
3130 No changes since last version.
3132 * Version 2.9.12 (released 2010-06-17)
3134 ** gnutls-cli: Make --starttls work again.
3135 Problem introduced in patch to use read() instead of fgets() committed
3138 ** API and ABI modifications:
3139 No changes since last version.
3141 * Version 2.9.11 (released 2010-06-07)
3143 ** libgnutls: Removed two APIs related to safe renegotiation.
3144 Use priority strings instead. The APIs were
3145 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
3146 (Remember that we don't promise ABI stability during development
3147 series, so this doesn't cause an shared library ABI increment.)
3149 ** tests: More self testing of safe renegotiation extension.
3150 See tests/safe-renegotiation/README for more information.
3152 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
3154 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
3156 ** API and ABI modifications:
3157 gnutls_safe_negotiation_set_initial: REMOVED.
3158 gnutls_safe_renegotiation_set: REMOVED.
3160 * Version 2.9.10 (released 2010-04-22)
3162 ** libgnutls: Time verification extended to trusted certificate list.
3163 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
3166 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
3167 Based on patch by Pavan Konjarla. Adds new constant
3168 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
3170 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
3171 Solves the issue discussed in:
3172 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
3173 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
3174 Note that to allow connecting to unpatched servers the full protection
3175 is only enabled if the priority string %SAFE_RENEGOTIATION is
3176 specified. You can check whether protection is in place by querying
3177 gnutls_safe_renegotiation_status(). New error codes
3178 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
3179 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
3181 ** libgnutls: When checking openpgp self signature also check the signatures
3183 Ilari Liusvaara noticed and reported the issue and provided test
3186 ** libgnutls: Added cryptodev support (/dev/crypto).
3187 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
3188 benchmark utility for AES. Adds new error codes
3189 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
3191 ** libgnutls: Exported API to access encryption and hash algorithms.
3192 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
3193 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
3194 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
3195 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
3196 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
3197 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
3198 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
3200 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
3201 verification of certificate upon receipt rather than waiting until the
3202 end of the handshake.
3204 ** libgnutls: Don't send alerts during handshake.
3205 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
3207 ** certtool: Corrected two issues that affected certificate request generation.
3208 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
3209 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
3210 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
3211 those parameters there since other implementations don't do either and having
3212 them does not seem to offer anything (anyway you need the signer's certificate
3213 to verify thus public key will be available). Found thanks to Boyan Kasarov.
3214 This however has the side-effect that public key IDs shown by certtool are
3215 now different than previous gnutls releases.
3216 (3) the option --pgp-certificate-info will verify self signatures
3218 ** certtool: Allow exporting of Certificate requests on DER format.
3220 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
3222 ** gnutls-cli: Handle reading binary data from server.
3223 Reported by and tiny patch from Vitaly Mayatskikh
3224 <v.mayatskih@gmail.com> in
3225 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/4096>.
3227 ** minitasn1: Upgraded to libtasn1 version 2.6.
3229 ** i18n: Updated Czech, Dutch, French, Polish, Swedish translation.
3230 ** Added Italian and Simplified Chinese translation.
3231 Thanks to Petr Pisar, Erwin Poeze, Nicolas Provost, Jakub Bogusz,
3232 Daniel Nylander, Sergio Zanchetta, Tao Wei, and Aron Xu.
3234 ** doc: The GTK-DOC manual is significantly improved.

3275 ** libgnutls: Cleanups and several bug fixes.
3276 Found by Steve Grubb and Tomas Mraz.
3278 ** Link libgcrypt explicitly to certtool, gnutls-cli, gnutls-serv.
3280 ** Fix --disable-valgrind-tests.
3281 Reported by Ingmar Vanhassel in
3282 <https://savannah.gnu.org/support/?107029>.
3284 ** API and ABI modifications:
3285 No changes since last version.
3287 * Version 2.9.8 (released 2009-11-05)
3289 ** libgnutls: Fix for memory leaks on interrupted handshake.
3290 Reported by Tang Tong.
3292 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
3293 ** extension and certificate verify field.

3382 ** libgnutls: When printing X.509 certificates, handle XMPP SANs better.
3383 Reported by Howard Chu <hyc@symas.com> in
3384 <https://savannah.gnu.org/support/?106975>.
3386 ** Fix use of deprecated types internally.
3387 Use of deprecated types in GnuTLS from now on will lead to a compile
3388 error, to prevent this from happening again.
3390 ** API and ABI modifications:
3391 No changes since last version.
3393 * Version 2.9.3 (released 2009-08-19)
3395 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
3396 The new APIs are gnutls_session_ticket_enable_client,
3397 gnutls_session_ticket_enable_server, and
3398 gnutls_session_ticket_key_generate.

3407 * Version 2.9.2 (released 2009-08-14)
3409 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
3410 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
3411 into 1) not printing the entire CN/SAN field value when printing a
3412 certificate and 2) cause incorrect positive matches when matching a
3413 hostname against a certificate. Some CAs apparently have poor
3414 checking of CN/SAN values and issue these (arguable invalid)
3415 certificates. Combined, this can be used by attackers to become a
3416 MITM on server-authenticated TLS sessions. The problem is mitigated
3417 since attackers needs to get one certificate per site they want to
3418 attack, and the attacker reveals his tracks by applying for a
3419 certificate at the CA. It does not apply to client authenticated TLS
3420 sessions. Research presented independently by Dan Kaminsky and Moxie
3421 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
3422 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
3424 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
3425 The function may fail incorrectly when an earlier certificate was
3426 imported to the same gnutls_x509_crt_t structure.
3428 ** minitasn1: Internal copy updated to libtasn1 v2.3.
3430 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
3431 Before it always returned false. Reported by Peter Hendrickson

3435 ** libgnutls: Fix off-by-one size computation error in unknown DN printing.
3436 The error resulted in truncated strings when printing unknown OIDs in
3437 X.509 certificate DNs. Reported by Tim Kosse

3441 ** libgnutls: Fix PKCS#12 decryption from password.
3442 The encryption key derived from the password was incorrect for (on
3443 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
3444 Tomas" <tomas.kukosa@siemens-enterprise.com> in

3448 gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
3449 gnutls_dh_get_peers_public_bits. Before the reported value was

3451 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3607>.

3459 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
3460 Before we required that the runtime library used the same (or more
3461 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
3462 that the runtime usage is above the minimum required. Reported by
3463 Marco d'Itri <md@linux.it> via Andreas Metzler
3464 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.

3502 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
3503 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
3505 Note: As a side effect of this change, the "public key identifier"
3506 value computed for a certificate using this version of GnuTLS will be
3507 different from values computed using earlier versions of GnuTLS.
3509 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
3510 ** optional SignatureAlgorithm parameter field.
3511 VeriSign rejected these CSRs. They are stricly speaking not needed
3512 since you need the signer's certificate to verify the certificate
3513 signature anyway. Reported by Wilankar Trupti

3773 No offically supported interfaces have been modified or removed. The
3774 library should be completely backwards compatible on both the source
3777 The shared library no longer exports some symbols that have never been
3778 officially supported, i.e., not mentioned in any of the header files.
3784 Normally when symbols are removed, the shared library version has to
3785 be incremented. This leads to a significant cost for everyone using
3786 the library. Because none of the above symbols have ever been
3787 intended for use by well-behaved applications, we decided that the it
3788 would be better for those applications to pay the price rather than
3789 incurring problems on the majority of applications.

3792 interfaces, we will need to release a follow-on release on the v2.8
3793 branch to exports additional interfaces. However, initial testing
3794 suggests that few if any applications have been using any of the
3797 Although not a new change compared to 2.6.x, we'd like to remind you
3798 interfaces have been modified so that X.509 chain verification now

3970 ** libgnutls: Fix DSA key generation.
3971 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
3973 ** libgnutls: Check expiration/activation time on untrusted certificates.
3974 Merged from stable branch. Reported by Romain Francoise
3975 <romain@orebokech.com>. This changes the semantics of
3976 gnutls_x509_crt_list_verify, which in turn is used by
3977 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
3978 We add two new gnutls_certificate_status_t codes for reporting the new
3979 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
3980 We also add a new gnutls_certificate_verify_flags flag,
3981 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
3982 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
3984 ** lib: Linker version scripts reduces number of exported symbols.
3985 The linker version script now lists all exported ABIs explicitly, to
3986 avoid accidentally exporting unintended functions. Compared to
3987 before, most symbols beginning with _gnutls* are no longer exported.
3988 These functions have never been intended for use by applications, and
3989 there were no prototypes for these function in the public header
3990 files. Thus we believe it is possible to do this without incrementing
3991 the library ABI version which normally has to be done when removing an
3994 ** lib: Limit exported symbols on systems without LD linker scripts.
3995 Before all symbols were exported. Now we limit the exported symbols
3996 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
3997 _gnutls*. This is a superset of the actual supported ABI, but still
3998 an improvement compared to before. This is implemented using Libtool
3999 -export-symbols-regex. It is more portable than linker version
4002 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
4003 This should have been done in the last release.
4005 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
4006 Reported by Peter Hendrickson <pdh@wiredyne.com> in
4007 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
4009 ** doc: Improved sections for the info manual.
4010 We now follow the advice given by the texinfo manual on which
4011 directory categories to use. In particular, libgnutls moved from the
4012 'GNU Libraries' section to the 'Software libraries' and the command
4013 line tools moved from 'Network Applications' to 'System

4026 ** libgnutls: Applied patch by Cedric Bail to add functions
4027 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().

4040 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
4041 It is currently only used by the core library. This will enable a new
4042 domain 'gnutls' for translations of the command line tools.
4044 ** Corrected possible memory corruption on signature verification failure.
4045 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
4047 ** API and ABI modifications:
4048 gnutls_x509_crt_verify_hash: ADDED
4049 gnutls_x509_crt_get_verify_algorithm: ADDED
4051 * Version 2.7.6 (released 2009-02-27)
4053 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
4054 This applies both to generating certificates and certificate requests.
4056 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
4058 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
4059 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
4060 be used for chain verification.
4062 ** gnutls-serv: No longer disable MAC padding by default.
4063 Use --priority NORMAL:%COMPAT to disable MAC padding again.
4065 ** gnutls-cli: Certificate information output format changed.
4066 The tool now uses libgnutls' functions to print certificate
4067 information. This avoids code duplication.
4069 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
4070 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
4071 They can be used to override the default certificate chain validation
4074 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
4075 specify the client hello message record version. Used to overcome buggy
4076 TLS servers. Report by Martin von Gagern.
4078 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
4080 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
4082 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
4084 ** API and ABI modifications:
4085 No changes since last version.
4087 * Version 2.7.5 (released 2009-02-06)
4089 ** libgnutls: Accept chains where intermediary certs are trusted.
4090 Before GnuTLS needed to validate the entire chain back to a
4091 self-signed certificate. GnuTLS will now stop looking when it has
4092 found an intermediary trusted certificate. The new behaviour is
4093 useful when chains, for example, contains a top-level CA, an
4094 intermediary CA signed using RSA-MD5, and an end-entity certificate.
4095 To avoid chain validation errors due to the RSA-MD5 cert, you can
4096 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
4097 The signature on trusted certificates are not checked, so the chain
4098 has a chance to validate correctly. Reported by "Douglas E. Engert"
4099 <deengert@anl.gov> in
4100 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
4102 ** libgnutls: result_size in gnutls_hex_encode now holds
4103 the size of the result. Report by John Brooks <special@dereferenced.net>.
4105 ** libgnutls: gnutls_handshake when sending client hello during a
4106 rehandshake, will not offer a version number larger than the current.
4107 Reported by Tristan Hill <stan@saticed.me.uk>.
4109 ** libgnutls: Permit V1 Certificate Authorities properly.
4110 Before they were mistakenly rejected even though
4111 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
4112 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
4113 "Douglas E. Engert" <deengert@anl.gov> in
4114 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
4116 ** API and ABI modifications:
4117 No changes since last version.
4119 * Version 2.7.4 (released 2009-01-07)
4121 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
4122 This is a bugfix -- the previous attempt to do this from internal x509
4123 certificate verification procedures did not return the correct value
4124 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
4125 <dkg@fifthhorseman.net> in
4126 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
4127 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
4128 Gillmor <dkg@fifthhorseman.net>.
4130 ** libgnutls: New interface to get key id for certificate requests.
4131 Patch from David Marín Carreño <davefx@gmail.com> in
4132 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
4134 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
4136 ** certtool: --verify-chain now prints results of using library verification.
4137 Earlier, certtool --verify-chain used its own validation algorithm
4138 which wasn't guaranteed to give the same result as the libgnutls
4139 internal validation algorithm. Now this command print a new final
4140 line with header 'Chain verification output:' that contains the result
4141 from using the internal verification algorithm on the same chain.
4143 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
4145 ** API and ABI modifications:
4146 gnutls_x509_crq_get_key_id: ADDED.
4148 * Version 2.7.3 (released 2008-12-10)
4150 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
4151 Reported by Michael Kiefer <Michael-Kiefer@web.de> in
4152 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507633> forwarded by
4153 Andreas Metzler <ametzler@downhill.at.eu.org> in
4154 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
4156 ** libgnutls: Libgcrypt initialization changed.
4157 If libgcrypt has not already been initialized, GnuTLS will now
4158 initialize libgcrypt with disabled secure memory. Initialize
4159 libgcrypt explicitly in your application if you want to enable secure
4160 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
4161 allocation functions, which doesn't use secure memory, so there is no
4162 real change in behaviour.
4164 ** libgnutls: Fix memory leak in PSK authentication.
4165 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
4166 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
4168 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
4170 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
4171 It needs to be invoked before libgcrypt is initialized.
4173 ** gnutls-cli: Return non-zero exit code on error conditions.
4175 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
4177 ** tests: Added chainverify self-test that tests X.509 chain verifications.
4179 ** API and ABI modifications:
4180 No changes since last version.
4182 * Version 2.7.2 (released 2008-11-18)
4184 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
4185 The flaw makes it possible for man in the middle attackers (i.e.,
4186 active attackers) to assume any name and trick GnuTLS clients into
4187 trusting that name. Thanks for report and analysis from Martin von
4188 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
4190 Any updates with more details about this vulnerability will be added
4191 to <http://www.gnu.org/software/gnutls/security.html>
4193 ** libgnutls: Fix namespace issue with version symbols.
4194 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
4195 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
4196 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
4197 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
4198 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
4199 work but are deprecated.
4201 ** certtool: allow setting arbitrary key purpose object identifiers.
4203 ** libgnutls: Fix detection of C99 macros, to make debug logging work again.
4205 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
4206 Reported by Kevin Quick <quick@sparq.org> in

4214 ** libgnutls: Change detection of when to use a linker version script.
4215 Use --enable-ld-version-script or --disable-ld-version-script to
4216 override auto-detection logic.
4218 ** doc: Change license on the manual to GFDLv1.3+.

4282 ** libgnutlsxx: Define server_session::get_srp_username even if no SRP.
4284 ** tests: Make tests compile when using internal libtasn1.
4285 Patch by ludo@gnu.org (Ludovic Courtès).
4287 ** Changed detection of libtasn1 and libgcrypt to avoid depending on *-config.
4288 We now require a libgcrypt that has Camellia constants declared in
4289 gcrypt.h, which means v1.3.0 or later.

4317 * Version 2.6.6 (released 2009-04-30)
4319 ** libgnutls: Corrected double free on signature verification failure.
4320 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
4321 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
4323 ** libgnutls: Fix DSA key generation.
4324 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
4325 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
4326 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
4328 ** libgnutls: Check expiration/activation time on untrusted certificates.
4329 Reported by Romain Francoise <romain@orebokech.com>. Before the
4330 library did not check activation/expiration times on certificates, and
4331 was documented as not doing so. We have realized that many
4332 applications that use libgnutls, including gnutls-cli, fail to perform
4333 proper checks. Implementing similar logic in all applications leads
4334 to code duplication. Hence, we decided to check whether the current
4335 time (as reported by the time function) is within the
4336 activation/expiration period of certificates when verifying untrusted
4339 This changes the semantics of gnutls_x509_crt_list_verify, which in
4340 turn is used by gnutls_certificate_verify_peers and
4341 gnutls_certificate_verify_peers2. We add two new
4342 gnutls_certificate_status_t codes for reporting the new error
4343 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
4344 add a new gnutls_certificate_verify_flags flag,
4345 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
4348 More details about the vulnerabilities will be posted at
4349 <http://www.gnu.org/software/gnutls/security.html>.
4351 ** gnutls-cli, gnutls-cli-debug: Fix AIX build problem.
4352 Reported by LAUPRETRE François (P) <francois.laupretre@ratp.fr> in
4353 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3468>.
4355 ** tests: Fix linking of tests/openpgp/keyring self-test.
4356 Reported by Daniel Black in <https://savannah.gnu.org/support/?106543>.
4358 ** API and ABI modifications:
4359 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
4360 gnutls_certificate_verify_peers: Likewise.
4361 gnutls_certificate_verify_peers2: Likewise.
4362 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
4363 GNUTLS_CERT_EXPIRED: ADDED.
4364 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
4366 * Version 2.6.5 (released 2009-04-11)
4368 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
4369 specify the client hello message record version. Used to overcome buggy
4370 TLS servers. Report by Martin von Gagern.
4372 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
4373 Libtasn1 0.3.4 or later is required. This is to align with the
4374 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
4376 ** API and ABI modifications:
4377 No changes since last version.
4379 * Version 2.6.4 (released 2009-02-06)
4381 ** libgnutls: Accept chains where intermediary certs are trusted.
4382 Before GnuTLS needed to validate the entire chain back to a
4383 self-signed certificate. GnuTLS will now stop looking when it has
4384 found an intermediary trusted certificate. The new behaviour is
4385 useful when chains, for example, contains a top-level CA, an
4386 intermediary CA signed using RSA-MD5, and an end-entity certificate.
4387 To avoid chain validation errors due to the RSA-MD5 cert, you can
4388 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
4389 The signature on trusted certificates are not checked, so the chain
4390 has a chance to validate correctly. Reported by "Douglas E. Engert"
4391 <deengert@anl.gov> in
4392 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
4394 ** libgnutls: result_size in gnutls_hex_encode now holds
4395 the size of the result. Report by John Brooks <special@dereferenced.net>.
4397 ** libgnutls: gnutls_handshake when sending client hello during a
4398 rehandshake, will not offer a version number larger than the current.
4399 Reported by Tristan Hill <stan@saticed.me.uk>.
4401 ** libgnutls: Permit V1 Certificate Authorities properly.
4402 Before they were mistakenly rejected even though
4403 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
4404 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
4405 "Douglas E. Engert" <deengert@anl.gov> in
4406 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
4408 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
4409 This is a bugfix -- the previous attempt to do this from internal x509
4410 certificate verification procedures did not return the correct value
4411 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
4412 <dkg@fifthhorseman.net> in
4413 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
4414 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
4415 Gillmor <dkg@fifthhorseman.net>.
4417 ** libgnutls: Fix compile error with Sun CC.
4418 Reported by Jeff Cai <jeff.cai@sun.com> in
4419 <https://savannah.gnu.org/support/?106549>.
4421 ** API and ABI modifications:
4422 No changes since last version.
4424 * Version 2.6.3 (released 2008-12-12)
4426 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
4427 Reported by Michael Kiefer <Michael-Kiefer@web.de> in
4428 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507633> forwarded by
4429 Andreas Metzler <ametzler@downhill.at.eu.org> in
4430 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
4432 ** libgnutls: Fix memory leak in PSK authentication.
4433 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
4434 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
4436 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
4437 It needs to be invoked before libgcrypt is initialized.
4439 ** gnutls-cli: Return non-zero exit code on error conditions.
4441 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
4443 ** API and ABI modifications:
4444 No changes since last version.
4446 * Version 2.6.2 (released 2008-11-12)
4448 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
4449 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
4450 problem for certificate chains that contained just one self-signed
4451 certificate. Reported by Michael Meskes <meskes@debian.org> in
4452 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505279>.
4454 ** API and ABI modifications:
4455 No changes since last version.
4457 * Version 2.6.1 (released 2008-11-10)
4459 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
4460 The flaw makes it possible for man in the middle attackers (i.e.,
4461 active attackers) to assume any name and trick GnuTLS clients into
4462 trusting that name. Thanks for report and analysis from Martin von
4463 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
4465 Any updates with more details about this vulnerability will be added
4466 to <http://www.gnu.org/software/gnutls/security.html>
4468 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
4469 Reported by Kevin Quick <quick@sparq.org> in
4470 <https://savannah.gnu.org/support/index.php?106454>.
4472 ** libgnutls-extra: Protect internal symbols with static.
4473 Fixes problem when linking certtool statically. Tiny patch from Aaron
4474 Ucko <ucko@ncbi.nlm.nih.gov>.
4476 ** libgnutls-openssl: Fix patch against X509_get_issuer_name.
4477 It incorrectly returned the subject DN instead of issuer DN in v2.6.0.
4478 Thanks to Thomas Viehmann <tv@beamnet.de> for report.
4480 ** certtool: Print a PKCS #8 key even if it is not encrypted.
4482 ** tests: Make tests compile when using internal libtasn1.
4483 Patch by ludo@gnu.org (Ludovic Courtès).
4485 ** API and ABI modifications:
4486 No changes since last version.
4488 * Version 2.6.0 (released 2008-10-06)
4490 ** libgnutls: Correct printing and parsing of IPv6 addresses.
4492 ** libgnutls-openssl: fix out of bounds access.
4493 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
4494 from Thomas Viehmann <tv@beamnet.de>.
4496 ** certtool: Use inet_pton for parsing IPv6 addresses.
4498 ** Major changes compared to the v2.4 branch:
4500 *** Added API to replace and update the crypto backend.
4502 *** certtool: can add several subject alternative names via template file.
4504 *** opencdk: Parse (but not decrypt) encrypted secret keys.
4506 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
4507 either set or append alternative names. It can also handle binary structures
4508 such as IP addresses.
4510 *** libgnutls: New function to set minimum acceptable SRP bits.
4511 The function is gnutls_srp_set_prime_bits.
4513 *** libgnutls: Add interface to deal with public key and signature algorithms.
4514 The functions are called gnutls_pk_list, gnutls_pk_get_id,
4515 gnutls_sign_list, and gnutls_sign_get_id.
4517 *** libgnutls: New interfaces to get name of public key and signing algorithms.
4518 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
4520 *** libgnutls: New API to get a string corresponding to a error symbol.
4521 The function is gnutls_strerror_name.
4523 *** libgnutls: New API to set the public parameters in a certificate request
4524 *** from a private key.
4525 The function is gnutls_x509_crq_set_key_rsa_raw.
4527 *** libgnutls: New API to set a callback to extract TLS Finished data.
4528 The function to register is gnutls_session_set_finished_function and
4529 it takes a callback of the gnutls_finished_callback_func type.
4531 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
4533 *** libgnutls: New interface to register a new TLS extension handler.
4534 The new function gnutls_ext_register can be used to register handlers
4535 for specific TLS extension types. The callback functions have the new
4536 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
4537 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
4540 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
4541 The function is gnutls_register_md5_handler. When libgcrypt is in
4542 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
4545 *** API/ABI changes in GnuTLS 2.6
4546 No functions have been removed or modified. The library should be
4547 fully backwards compatible on both the source and binary level.
4549 A new header file <gnutls/crypto.h> have been added. It contains
4550 definitions related to replacing the internal crypto functionality.
4551 All definitions and the header itself is experimental but supported.
4553 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
4554 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
4555 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
4557 The following functions have been added to libgnutls:
4561 gnutls_crypto_bigint_register2
4562 gnutls_crypto_cipher_register2
4563 gnutls_crypto_digest_register2
4564 gnutls_crypto_mac_register2
4565 gnutls_crypto_pk_register2
4566 gnutls_crypto_rnd_register2
4567 gnutls_crypto_single_cipher_register2

4584 The following functions have been added to libgnutls-extra:
4586 gnutls_register_md5_handler
4588 ** API and ABI modifications:
4589 No changes since last version.
4591 * Version 2.5.9 (released 2008-09-29)
4593 ** libgnutls: Fix several memory leaks.
4594 Reported by Sam Varshavchik <mrsam@courier-mta.com>.
4596 ** libgnutls: Fix buffer overrun in gnutls_x509_crt_list_import.
4597 Report and patch by Jonathan Manktelow.
4599 ** libgnutls: crypto.h gnutls_pk_params_st changes allocation strategy.
4600 The parameters are now allocated in the structure itself.
4602 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
4604 ** tests: Scripts now use EXEEXT properly.
4605 Modern libtool doesn't create wrapper script, so the self tests need
4606 to invoke certtool.exe under MinGW32+Wine.
4608 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
4609 Automake warnings are now also enabled.
4611 ** API and ABI modifications:
4612 gnutls_pk_params_st: MODIFIED
4614 * Version 2.5.8 (released 2008-09-21)
4616 ** certtool: updated so it can add several subject alternative names using
4619 ** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
4620 either set or append alternative names. It can also handle binary structures
4621 such as IP addresses.
4623 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
4625 ** libgnutls: New function to set minimum acceptable SRP bits.
4626 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick
4627 <quick@sparq.org> in <https://savannah.gnu.org/support/index.php?106454>.
4629 ** libgnutls: Check for overflows in gnutls_calloc and gnutls_secure_calloc.
4630 Also fix overflows in calls to those functions. Reported by Werner
4631 Koch <wk@gnupg.org>.
4633 ** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.

4646 gnutls_x509_crt_set_subject_alt_name: ADDED
4648 * Version 2.5.7 (released 2008-09-16)
4650 ** libgnutls: New interfaces to get name of public key and signing algorithms.
4651 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
4653 ** libgnutls: Don't crash when gnutls_credentials_set is called twice.
4655 ** libgnutls: Fix libgnutls shared library version.
4656 It wasn't properly incremented after adding symbols in the last
4659 ** manual: Now mention supported public key and public key signing algorithms.
4661 ** tests/openssl: initialize gnutls before use.
4663 ** tests/setcredcrash: New test to catch regressions of gnutls_credentials_set.
4665 ** GTK-DOC manual: mention new symbols in 2.6.x. Mention crypto.h functions.
4667 ** API and ABI modifications:
4668 gnutls_sign_get_name: ADDED
4669 gnutls_pk_get_name: ADDED
4671 * Version 2.5.6 (released 2008-09-08)
4673 ** libgnutls: Add interface to deal with public key and signature algorithms.
4674 The functions are called gnutls_pk_list, gnutls_pk_get_id,
4675 gnutls_sign_list, and gnutls_sign_get_id. Suggested by Sam
4676 Varshavchik <mrsam@courier-mta.com>.
4678 ** libgnutls: Refactor and clean up some code.
4680 ** libgnutls: Fix compile error with Sun CC.

4684 ** gnutls-cli, gnutls-serv: Remove --copyright parameter.
4685 Use standard --version to get license info.
4687 ** gnutls-cli.1: Document all new parameters.
4688 Thanks to James Westby <jw+debian@jameswestby.net>.
4690 ** tests: New self-test pgps2kgnu to test parsing of encrypted secrets.
4691 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
4693 ** API and ABI modifications:
4694 gnutls_pk_list: ADDED
4695 gnutls_pk_get_id: ADDED
4696 gnutls_sign_list: ADDED
4697 gnutls_sign_get_id: ADDED
4699 * Version 2.5.5 (released 2008-08-29)
4701 ** libgnutls: New API to get a string corresponding to a error symbol.
4702 The function is gnutls_strerror_name.
4704 ** libgnutls: Fix include paths so that building with internal libtasn1 works.
4705 Reported by "jth.net ApS" <info@jth.net>.
4707 ** libgnutls: Fix segmentation fault when generating private keys.
4708 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
4710 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
4711 The code has not worked since v0.9.0 and apparently nobody has missed
4712 it, so we decided to remove the code rather than fix it. If you have
4713 old certificate chains stored in PKCS#7 format, you can convert them
4714 to a list of PEM certificates by using 'certtool --p7-info'. Reported
4715 by Christian Grothoff <christian@grothoff.org>.
4717 ** opencdk: Parse (but not decrypt) encrypted secret keys.
4718 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
4720 ** libgnutls: Fix many warnings.
4722 ** Included copy of libtasn1 is upgraded to version 1.5.
4724 ** Add French translation, thanks to Nicolas Provost.
4726 ** API and ABI modifications:
4727 gnutls_strerror_name: ADDED
4729 * Version 2.5.4 (released 2008-08-19)
4731 ** Fix secure memory initialization of libgcrypt.
4732 Reported by Joe Orton <joe@manyfish.co.uk> in
4733 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2992>.
4736 Reference to NIST SP 800-57 in the manual on key size recommendations.
4737 Added 'Since:' tags to new APIs for gtk-doc.
4739 ** API and ABI modifications:
4740 No changes since last version.
4742 * Version 2.5.3 (released 2008-08-14)
4744 ** libgnutls: New API to set the public parameters in a certificate request
4745 ** from a private key.
4746 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
4747 discussion with "Zach C." <fxchip@gmail.com>.
4749 ** libgnutls: New API to set a callback to extract TLS Finished data.
4750 The function to register is gnutls_session_set_finished_function and
4751 it takes a callback of the gnutls_finished_callback_func type.
4753 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
4754 Reported in <https://savannah.gnu.org/support/?106453>.
4756 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
4757 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
4758 names are mapped to the new names in compat.h. These mappings will
4759 likely be removed more quickly than other mappings in that file due to
4760 the namespace violation.

4780 ** libgnutls: New interface to register a new TLS extension handler.
4781 The new function gnutls_ext_register can be used to register handlers
4782 for specific TLS extension types. The callback functions have the new
4783 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
4784 classify TLS extensions, gnutls_ext_parse_type_t, has been added as

4833 * Version 2.4.3 (released 2009-02-06)
4835 ** libgnutls: Accept chains where intermediary certs are trusted.
4836 Before GnuTLS needed to validate the entire chain back to a
4837 self-signed certificate. GnuTLS will now stop looking when it has
4838 found an intermediary trusted certificate. The new behaviour is
4839 useful when chains, for example, contains a top-level CA, an
4840 intermediary CA signed using RSA-MD5, and an end-entity certificate.
4841 To avoid chain validation errors due to the RSA-MD5 cert, you can
4842 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
4843 The signature on trusted certificates are not checked, so the chain
4844 has a chance to validate correctly. Reported by "Douglas E. Engert"
4845 <deengert@anl.gov> in
4846 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
4848 ** libgnutls: Permit V1 Certificate Authorities properly.
4849 Before they were mistakenly rejected even though
4850 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
4851 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by

4855 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
4856 This is a bugfix -- the previous attempt to do this from internal x509
4857 certificate verification procedures did not return the correct value
4858 for certificates using a weak hash. Reported by Daniel Kahn Gillmor

4942 ** API and ABI modifications:
4943 No changes since last version.
4945 * Version 2.4.0 (released 2008-06-19)
4947 ** Major changes compared to the v2.2 branch:
4949 *** The OpenPGP sub-system has been improved and now supports subkeys.
4951 *** The PSK sub-system has been improved and now supports password
4952 *** derivation and PSK identity hints.
4953 The password derivation algorithms support is documented in
4954 draft-ietf-netconf-tls-02.txt.
4956 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
4957 This aligns terminology with OpenPGP, which doesn't use DER encoding.
4958 The old parameters will continue to work for some time.
4960 *** Certtool now confirm passwords and changes permissions of private key files.
4962 *** The default handshake size limit has been increased to 48kb.
4963 It appears as if some valid handshakes are large due to sending many
4964 CA certificates. (The earlier limit was 16kb.)
4966 *** LZO compression is now disabled by default.
4967 The main reason is that LZO compression in TLS is not standardized,
4968 but license compatiblity issues with minilzo triggered us to make this
4971 *** Improvements for cross-compilation to Windows and OpenWRT.
4973 *** The look of the GTK-DOC manual has been improved.
4974 Major developer visible changes compared to the v2.2 branch:
4976 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
4978 *** New APIs to access the raw X.509 Subject and Issuer DN's and
4979 *** elements from the certificate credentials structure.
4980 Thanks to Joe Orton.
4982 *** New APIs to improve working with username/passwords and PSK.
4984 *** Names of constants to affect certificate printing changed.
4985 The constants are used for OpenPGP too, which the names didn't
4986 reflect, so the following name change has been made:
4989 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
4990 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
4991 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
4993 The old names will be mapped to the new names for some time.
4995 *** The function gnutls_openpgp_privkey_get_id has been renamed to
4996 *** gnutls_openpgp_privkey_get_key_id.
4997 A compatibility mapping exists to avoid breaking API backwards
5000 *** Replaced all uses of alloca with malloc and free.
5002 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
5003 We have been unable to find a documented rationale for this practice.
5005 *** Of course, many smaller fixes have been made, see the ChangeLog file.
5007 *** API/ABI changes in GnuTLS 2.4
5008 All OpenPGP related functions have been moved from libgnutls-extra to
5009 libgnutls, and several new functions have been added (see below).
5010 Before making the release, we discussed whether moving functions from
5011 libgnutls-extra to libgnutls would require us to increment the ABI
5012 version, but the general opinion was that this would not be required.
5013 All older functions continue to work the same. We are open to the
5014 possibility that this decision will lead to problem on some platform,
5015 and if it turns out that the Right Thing should have been to increment
5016 the shared library version, we would need to release an update within
5017 the 2.4.x branch that increments the shared library version.
5019 This release adds the following functions:
5021 gnutls_psk_client_get_hint
5022 gnutls_psk_set_server_credentials_hint
5023 gnutls_psk_netconf_derive_key
5025 Used to get/set the PSK identity hint, and derive PSK keys from
5026 passwords a'la netconf.
5028 gnutls_x509_dn_deinit
5029 gnutls_x509_dn_export
5030 gnutls_x509_dn_import
5033 Used to handle X.509 Certificate DN's directly.
5037 Converts a data buffer to hex. Useful for handling PSK/SRP shared
5040 gnutls_certificate_get_x509_cas
5041 gnutls_certificate_get_x509_crls
5042 gnutls_certificate_get_openpgp_keyring
5044 Functions for direct access to credential elements.

5084 gnutls_openpgp_privkey_get_subkey_revoked_status
5085 gnutls_openpgp_privkey_set_preferred_key_id
5087 New OpenPGP related functions.
5089 The function gnutls_openpgp_crt_get_key_id is the same as the old
5090 from gnutls_openpgp_crt_get_id, see above.
5092 The release also adds a new header file 'gnutls/crypto.h', however it
5093 is currently not used.

5127 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
5129 ** doc/: Add psktool to info index. Some minor cleanups.
5131 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
5133 ** tests/: Added libgcrypt.supp which can be used with valgrind.
5134 The file suppresses the known libgcrypt memory leaks, so they aren't
5135 printed when you run valgrind on the gnutls self-tests. Use it as
5136 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add

5152 * Version 2.3.12 (released 2008-06-04)
5154 ** Merge gnutls_with_netconf branch.
5156 *** libgnutls [PSK]: New API to retrieve PSK identity hint in client.
5157 The function is gnutls_psk_client_get_hint.
5159 *** libgnutls [PSK]: New API to set PSK identity hint in server.
5160 The function is gnutls_psk_set_server_credentials_hint.
5162 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
5163 In the client, the message is parsed and the application can use
5164 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
5165 message is sent if the application has specified a PSK identity hint
5166 using gnutls_psk_set_server_credentials_hint.
5168 *** libgnutls [PSK]: Support Netconf PSK key derivation.
5169 The function gnutls_psk_netconf_derive_key supports the PSK key
5170 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
5173 *** psktool: Support new --netconf-hint to generate PSK key from password.
5174 Uses the Netconf algorithm to derive PSK key from password.
5176 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
5178 *** gnutls-cli: Always support PSK modes, through a callback.
5179 The callback will derive a PSK key using Netconf algorithm. It will
5180 print the PSK identity hint to help the user.
5182 *** New PSK example client and server.
5183 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
5185 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.

5273 Also improve manual to give example for gnutls-cli PSK authentication.
5275 ** certtool: Encrypting a private key now require a confirmed password.
5276 Before './certtool -k -8' would merely ask for a password once.
5277 Reported by Daniel 'NebuchadnezzaR' Dehennin
5278 <nebuchadnezzar@asgardr.info> see
5279 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
5281 ** certtool: When writing private keys to files, change permissions of file.
5282 Now the file which the private key is saved to is chmod'ed 0600.
5283 Reported by martin f krafft <madduck@debian.org> see
5284 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
5286 ** guile: Fix -fgnu89-inline test.
5288 ** Removed --enable-profile-mode.
5289 The code linked gnutls with the libfc project (Function Check) which
5290 appears to have been stalled since around 2002.
5292 ** Clean up header file checks by ./configure.
5294 ** Update of gnulib files.
5296 ** API and ABI modifications:
5297 No changes since last version.
5299 * Version 2.3.8 (released 2008-04-29)
5301 ** libgnutls: Increase default handshake packet size limit to 48kb.
5302 The old limit was 16kb and some servers send huge list of trusted CAs,
5303 thus running into the limit. FYI, applications can further increase
5304 this limit using gnutls_handshake_set_max_packet_length. Thanks to
5305 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
5306 <marc@mclemente.net> for reporting and providing test servers.
5308 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
5309 Returned when the handshake data size is too large. Before
5310 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
5313 ** libgnutls: Hide definitions in crypto.h.
5314 We have decided that the APIs defined in crypto.h are not stable
5315 enough for v2.4, so don't use any of those functions.
5317 ** gnutls-cli: exit when hostname doesn't match certificate.
5318 Use --insecure to avoid hostname comparison.
5320 ** certtool: --inder and --outder replaced by --inraw and --outraw.
5321 The reason is to align terminology with OpenPGP, which doesn't use
5322 DER. The old parameters will continue to work for some time.
5324 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
5326 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
5328 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
5329 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
5330 vasprintf symbol from the libgcrypt library which caused problems.
5332 ** Update of gnulib files.
5334 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
5336 ** API and ABI modifications:
5337 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
5339 * Version 2.3.7 (released 2008-04-21)
5341 ** opencdk now properly sets the key usage bits into openpgp keys.
5343 ** gnutls-cli: Fix crash on TLS handshake failures.
5344 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
5345 This is similar to <http://bugs.debian.org/429183>.
5347 ** certtool: with --generate-request and newly generated keys, print the key.
5349 ** Build fixes for MinGW.
5350 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
5351 with -lws2_32 when needed. Use ASCII only isprint() when printing
5352 X.509 certificate information, to avoid non-ASCII but printable
5353 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
5356 ** Update internal copy of libtasn1 to version 1.4.
5358 ** API and ABI modifications:
5359 No changes since last version.
5361 * Version 2.3.6 (released 2008-04-17)
5363 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
5364 ** Improve documentation for gnutls_x509_crq_sign2.
5365 Based on report from "John Brooks" <aspecialj@gmail.com> in
5366 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
5368 ** tests/pathlen: run diff without parameters to improve portability.
5369 Based on HPUX build hints in
5370 <http://hpux.cs.utah.edu/hppd/cgi-bin/wwwtar?/hpux/Gnu/gnutls-2.3.4/gnutls-2.3.4-src-11.11.tar.gz+gnutls-2.3.4/HPUX.Install+text>.
5372 ** Don't use %e specifier with strftime, it doesn't work under Windows.
5373 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
5374 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
5376 ** Remove all uses of gnutls_alloca/gnutls_afree.
5377 Use normal gnutls_malloc instead. One reason is increased portability
5378 to Windows, the other is that several of the uses may be unsafe
5379 because the size of data allocated could be large. Reported by
5380 Massimo Gaspari <massimo.gaspari@alice.it> in
5381 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
5383 ** Build Guile code with -fgnu89-inline only when supported.
5384 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
5385 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
5387 ** Several GTK-DOC related fixes.
5389 ** Clean up OpenCDK related code.
5390 GnuTLS now requires its internal OpenCDK code rather than the external
5391 GPL library OpenCDK. Unfortunately, we don't have resources to
5392 maintain an external library (help welcome).
5394 ** API and ABI modifications:
5395 No changes since last version.
5397 * Version 2.3.5 (released 2008-04-14)
5399 ** Build fix for MinGW and --disable-shared.
5400 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
5401 <http://permalink.gmane.org/gmane.network.gnutls.general/1145>.
5403 ** Document how to generate CRLs.
5404 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
5406 ** Documented the --priority option to gnutls-cli and gnutls-serv.
5408 ** Several minor fixes in the OpenPGP interface.
5409 Thanks to Daniel Kahn Gillmor.
5411 ** Fix fopen file descriptor leak in PSK server code.
5412 Thanks to Laurence Withers <l@lwithers.me.uk>, see
5413 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
5415 ** Translations files not stored directly in git to avoid merge conflicts.
5417 ** New APIs to let applications replace the RNG used.
5418 Update all RNG callers in the code to use the new interface.
5420 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
5422 ** Update gnulib files.
5424 ** API and ABI modifications:
5425 gnutls_crypto_rnd_register: ADDED
5426 gnutls_rnd_level_t: ADDED
5427 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
5428 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
5429 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
5430 gnutls_crypto_rnd_st: ADDED
5431 GNUTLS_DIG_SHA224: ADDED
5432 GNUTLS_SIGN_RSA_SHA224: ADDED
5433 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
5435 * Version 2.3.4 (released 2008-03-19)
5437 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
5438 They weren't renamed in the public header file.
5440 ** Added functions to register a cipher/mac/digest. This allows to
5441 override the included ones.
5443 ** Fix a bunch of compiler warnings.
5445 ** API and ABI modifications:
5446 gnutls_crypto_cipher_st: ADDED
5447 gnutls_crypto_mac_st: ADDED
5448 gnutls_crypto_digest_st: ADDED
5449 gnutls_crypto_cipher_register: ADDED
5450 gnutls_crypto_mac_register: ADDED
5451 gnutls_crypto_digest_register: ADDED
5452 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
5454 * Version 2.3.3 (released 2008-03-10)
5456 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
5457 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
5459 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
5460 We could not find any modern justification for enabling these flags by
5461 default. If you know of some platform that needs one of the flags to
5462 work properly, please let us know. (Actually introduced in v2.3.0 but
5463 not documented until now.)
5465 ** Importing many CA certificates are now considerably faster.
5466 This affect gnutls_certificate_set_x509_trust_mem,
5467 gnutls_certificate_set_x509_trust, and
5468 gnutls_certificate_set_x509_trust_file. The complexity was reduced
5469 from O(2*n^2) to O(n). When adding 206 files containing 408
5470 certificates, using gnutls_certificate_set_x509_trust_file, the time
5471 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
5472 to trigger the problem. See also
5473 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
5475 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
5476 ** to be explicit that it takes zero terminated data.
5478 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
5480 ** Documentation fixes for the GTK-DOC manual.
5482 ** Fix compilation error related to __FUNCTION__ on some systems.
5483 Reported by Tim Mooney, see
5484 <https://savannah.gnu.org/support/?106267>.
5486 ** Updated translations.
5488 ** Update gnulib files.
5490 ** API and ABI modifications:
5491 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
5492 and char* instead of void* for output buffer.
5494 * Version 2.3.2 (released 2008-02-26)
5496 ** Fix srcdir!=objdir failure in openpgpself test.
5498 ** Improved API documentation output from GTK-DOC.
5500 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
5502 ** Renamed gnutls_certificate_export_x509_cas and friends.
5503 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
5505 ** Internal header files cleanup.
5507 ** API and ABI modifications:
5508 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
5509 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
5510 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
5511 gnutls_x509_dn_export: ADDED
5513 * Version 2.3.1 (released 2008-02-21)
5515 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
5516 The included copy of OpenCDK has been stripped down and re-licensed
5519 ** Cipher priority string handling now handle strings that starts with NULL.
5520 Thanks to Laurence Withers <l@lwithers.me.uk>.
5522 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
5524 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
5527 ** Increased the default certificate verification chain limits and allowed
5528 for checks without limitation.
5530 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
5531 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
5532 strings and return the proper size.
5534 ** Add section 'On Record Padding' to the manual.
5535 This collects all problems related to record padding with
5536 Nokia/Sony-Ericsson phones that we know about.
5538 ** Several improvements in the OpenPGP authentication.
5539 Now subkeys can be used for authentication, according to
5540 draft-mavrogiannopoulos-rfc5081bis-00.txt.
5542 ** certtool can print information on OpenPGP certificates and keys.
5544 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
5547 ** Added gnutls_certificate_export_x509_cas and other functions to
5548 export elements from the certificate credentials structure. Based on
5549 suggestion from Joe Orton.
5552 Clarify that srp_base64 is not the same as normal base64.
5554 ** Fix non-portable use of brace expansion in makefiles.
5556 ** API and ABI modifications:
5557 gnutls_certificate_export_x509_cas: ADDED
5558 gnutls_certificate_export_x509_crls: ADDED
5559 gnutls_certificate_export_openpgp_keyring: ADDED
5560 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
5561 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
5562 gnutls_openpgp_crt_get_revoked_status: ADDED
5563 gnutls_openpgp_crt_get_subkey_count: ADDED
5564 gnutls_openpgp_crt_get_subkey_idx: ADDED
5565 gnutls_openpgp_crt_get_subkey_revoked_status: ADDED
5566 gnutls_openpgp_crt_get_subkey_pk_algorithm: ADDED
5567 gnutls_openpgp_crt_get_subkey_creation_time: ADDED
5568 gnutls_openpgp_crt_get_subkey_expiration_time: ADDED
5569 gnutls_openpgp_crt_get_subkey_id: ADDED
5570 gnutls_openpgp_crt_get_subkey_usage: ADDED

5598 GNUTLS_CRT_PRINT_ONELINE: ADDED, same as old GNUTLS_X509_CRT_ONELINE.
5599 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
5600 old GNUTLS_X509_CRT_UNSIGNED_FULL.
5602 * Version 2.3.0 (released 2008-01-08)
5604 ** LZO compression is now disabled by default.
5605 The reason is that LZO compression is not standardized in TLS. If you
5606 wish to experiment with it, you will have to supply --with-lzo when
5607 invoking ./configure. The internal copy of minilzo is no longer
5608 included with GnuTLS, so you will need to install liblzo or liblzo2 on
5609 your system to have --with-lzo to be effective.
5611 ** More than one server name field is now sent to the server properly.
5612 Thanks to mark.phillips@virgin.net.
5614 ** Fixes the post_client_hello_function(). The extensions are now parsed
5615 in a callback friendly way.
5617 ** Fix for certificate selection in servers with certificate callbacks.
5619 ** Updated translations.
5621 ** Update gnulib files.
5623 ** API and ABI modifications:
5624 No changes since last version.
5626 * Version 2.2.5 (released 2008-05-19)
5628 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
5629 The flaw would result in incorrectly terminated sessions with the
5630 error "Decryption has failed" when the server sends a small packet
5631 (typically when the session is closed). Reported by Andreas Metzler
5632 <ametzler@downhill.at.eu.org> in

5635 ** API and ABI modifications:
5636 No changes since last version.
5638 * Version 2.2.4 (released 2008-05-19)
5640 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
5641 Thanks to CERT-FI for finding the bugs and providing detailed reports,
5642 which allowed the bugs to be reproduced and fixed easily. Patches
5643 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
5644 with more details about these vulnerabilities will be added to
5645 <http://www.gnu.org/software/gnutls/security.html>
5647 *** [GNUTLS-SA-2008-1-1]
5648 *** libgnutls: Fix crash when sending invalid server name.
5649 The crash can be triggered remotely before authentication, which can
5650 lead to a Daniel of Service attack to disable the server. The bug
5651 cause gnutls to store more session resumption data than what was
5652 allocated for, thus overwriting unallocated memory.
5654 *** [GNUTLS-SA-2008-1-2]
5655 *** libgnutls: Fix crash when sending repeated client hellos.
5656 The crash can be triggered remotely before authentication, which can
5657 lead to a Daniel of Service attack to disable the server. The bug
5658 triggers a null-pointer dereference.
5660 *** [GNUTLS-SA-2008-1-3]
5661 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
5662 The crash can be triggered remotely before authentication, which can
5663 lead to a Daniel of Service attack to disable the server. The bug
5664 cause gnutls to read memory beyond the end of the received record.
5666 ** API and ABI modifications:
5667 No changes since last version.
5669 * Version 2.2.3 (released 2008-05-06)
5671 ** Increase default handshake packet size limit to 48kb.
5672 The old limit was 16kb and some servers send huge list of trusted CAs,
5673 thus running into the limit. FYI, applications can further increase
5674 this limit using gnutls_handshake_set_max_packet_length. Thanks to
5675 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"

5678 ** Fix compilation error related to __FUNCTION__ on some systems.
5679 Reported by Tim Mooney, see
5680 <https://savannah.gnu.org/support/?106267>.
5682 ** Documented the --priority option to gnutls-cli and gnutls-serv.

5694 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
5696 ** API and ABI modifications:
5697 No changes since last version.
5699 * Version 2.2.2 (released 2008-02-21)
5701 ** Cipher priority string handling now handle strings that starts with NULL.
5702 Thanks to Laurence Withers <l@lwithers.me.uk>.
5704 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
5707 ** Increased the default certificate verification chain limits and allowed

5710 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
5711 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
5712 strings and return the proper size.
5714 ** API and ABI modifications:
5715 No changes since last version.
5717 * Version 2.2.1 (released 2008-01-17)
5719 ** Prevent linking libextra against previously installed libgnutls.
5720 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
5721 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
5723 ** Fixes the post_client_hello_function(). The extensions are now parsed
5724 in a callback friendly way.
5726 ** Fix for certificate selection in servers with certificate callbacks.
5728 ** API and ABI modifications:
5729 No changes since last version.
5731 * Version 2.2.0 (released 2007-12-14)
5733 ** Update internal copy of libtasn1 to version 1.2.
5735 ** Certtool --verify-chain now handle inputs larger than 64kb.
5736 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
5737 recent versions of libgcrypt. The problem was that Wine with the
5738 libgcrypt RNG generates huge amounts of debugging output.
5740 ** Translation updates.
5741 Added Dutch translation. Updated Polish and Swedish translation.
5743 ** Major changes compared to the v2.0 branch:
5745 *** SRP support aligned with newly published RFC 5054.
5747 *** OpenPGP support aligned with newly published RFC 5081.
5749 *** Support for DSA2 keys.
5751 *** Support for Camellia cipher.
5753 *** Support for Opaque PRF Input extension.
5755 *** PKCS#8 parser now handle DSA keys.
5757 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
5758 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
5759 versions, such as 2.01 which is included with GnuTLS, is available
5760 under GPLv2 or later. If this incompatibility causes problems, we
5761 recommend you to disable LZO using --without-lzo. LZO compression is
5762 not a standard TLS compression algorithm, so the impact should be
5765 *** Functions for disabling record protocol padding.
5766 Works around bugs on Nokia/Ericsson phones.
5768 *** New functions gnutls_priority_set() for setting cipher priorities easily.
5769 Priorities like "COMPAT" also enables other work arounds, such as
5772 *** Other minor improvements and bug fixes.
5774 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
5775 To adapt to changes in the TLS extension specifications for OpenPGP
5776 and SRP, the GnuTLS API had to be modified. This means breaking the
5777 API and ABI backwards compatibility. That is something we try to
5778 avoid unless it is necessary. We decided to also remove the already
5779 deprecated stub functions for X.509 to XML conversion and TLS
5780 authorization (see below) when we had the opportunity.
5782 Generally, most applications does not need to be modified. Just
5783 re-compile them against the latest GnuTLS release, and it should work
5786 Applications that use the OpenPGP or SRP features needs to be
5787 modified. Below is a list of the modified APIs and discussion of what
5788 the minimal things you need to modify in your application to make it
5789 work with GnuTLS 2.2.
5791 Note that GnuTLS 2.2 also introduces new APIs -- such as
5792 gnutls_set_priority() that is superior to
5793 gnutls_set_default_priority() -- that you may want to start using.
5794 However, using those new APIs is not required to use GnuTLS 2.2 since
5795 the old functions continue are still supported. This text only
5796 discuss what you minimally have to modify.
5798 *** XML related changes
5799 The function `gnutls_x509_crt_to_xml' has been removed. It has been
5800 deprecated and only returned an error code since GnuTLS version
5801 1.2.11. Nobody has complained, so users doesn't seem to miss the
5802 functionality. We don't know of any other library to convert X.509
5803 certificates into XML format, but we decided (long ago) that GnuTLS
5804 isn't the right place for this kind of functionality. If you want
5805 help to find some other library to use here, please explain and
5806 discuss your use case on help-gnutls@gnu.org.
5808 *** TLS Authorization related changes
5809 Everything related to TLS authorizations have been removed, they were
5810 only stub functions that returned an error code:
5812 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
5813 gnutls_authz_data_format_type_t
5814 gnutls_authz_recv_callback_func
5815 gnutls_authz_send_callback_func
5817 gnutls_authz_send_x509_attr_cert
5818 gnutls_authz_send_saml_assertion
5819 gnutls_authz_send_x509_attr_cert_url
5820 gnutls_authz_send_saml_assertion_url
5822 *** SRP related changes
5823 The callback gnutls_srp_client_credentials_function has a new
5824 prototype, and its semantic has changed. You need to rewrite the
5825 callback, see the updated function documentation and SRP example code
5826 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
5829 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
5830 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
5831 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
5832 used. There are #define's to map the old names to the new. You may
5833 run into problems if you have a switch-case with cases for both SRP
5834 alerts, since they are now mapped to the same value. The solution is
5835 to drop the SRP alerts from such switch cases, as they are now
5836 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
5838 *** OpenPGP related changes
5839 The function `gnutls_certificate_set_openpgp_keyserver' have been
5840 removed. There is no replacement functionality inside GnuTLS. If you
5841 need keyserver functionality, consider using the GnuPG tools.
5843 All functions, types, and error codes related to OpenPGP trustdb
5844 format have been removed. The trustdb format is a non-standard
5845 GnuPG-specific format, and we recommend you to use key rings instead.
5846 The following have been removed:
5848 gnutls_certificate_set_openpgp_trustdb
5849 gnutls_openpgp_trustdb_init
5850 gnutls_openpgp_trustdb_deinit
5851 gnutls_openpgp_trustdb_import
5852 gnutls_openpgp_key_verify_trustdb
5853 gnutls_openpgp_trustdb_t
5854 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
5856 The following functions has an added parameter of the (new) type
5857 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
5858 (binary or base64). The functions are:
5859 gnutls_certificate_set_openpgp_key_file
5860 gnutls_certificate_set_openpgp_key_mem
5861 gnutls_certificate_set_openpgp_keyring_mem
5862 gnutls_certificate_set_openpgp_keyring_file
5864 To improve terminology and align with the X.509 interface, some
5865 functions have been renamed. Compatibility mappings exists. The old
5866 and new names of the affected functions and types are:
5869 gnutls_openpgp_key_t gnutls_openpgp_crt_t
5870 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
5871 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
5872 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
5873 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
5874 gnutls_openpgp_key_init gnutls_openpgp_crt_init
5875 gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit
5876 gnutls_openpgp_key_import gnutls_openpgp_crt_import
5877 gnutls_openpgp_key_export gnutls_openpgp_crt_export
5878 gnutls_openpgp_key_get_key_usage gnutls_openpgp_crt_get_key_usage
5879 gnutls_openpgp_key_get_fingerprint gnutls_openpgp_crt_get_fingerprint
5880 gnutls_openpgp_key_get_pk_algorithm gnutls_openpgp_crt_get_pk_algorithm
5881 gnutls_openpgp_key_get_name gnutls_openpgp_crt_get_name
5882 gnutls_openpgp_key_get_version gnutls_openpgp_crt_get_version
5883 gnutls_openpgp_key_get_creation_time gnutls_openpgp_crt_get_creation_time
5884 gnutls_openpgp_key_get_expiration_time gnutls_openpgp_crt_get_expiration_time
5885 gnutls_openpgp_key_get_id gnutls_openpgp_crt_get_id
5886 gnutls_openpgp_key_check_hostname gnutls_openpgp_crt_check_hostname
5887 gnutls_openpgp_send_key gnutls_openpgp_send_cert
5889 ** API and ABI modifications:
5890 No changes since last version.
5892 * Version 2.1.8 (released 2007-12-10)
5894 ** The GPL version has been changed from version 2 to version 3.
5895 This affects the self-tests, command-line tools, the libgnutls-extra
5896 library, the relevant guile parts, and the build environment.
5898 ** Added gnutls_x509_crt_get_subject_alt_name2().
5900 ** Corrected a segfault when setting an empty gnutls_priority_t
5901 at gnutls_priority_set().

5911 ** PKCS #8 parser can now encode/decode DSA keys.
5913 ** Updated gnutls_set_default_priority2() now renamed to
5914 gnutls_priority_set() and gnutls_priority_set_direct() which
5915 accept a string to indicate preferences of ciphersuite parameters.
5917 ** gnutls-cli and gnutls-serv now have a --priority option to set
5918 the priority string.
5920 ** The gnutls_*_convert_priority() functions were deprecated by
5921 the gnutls_priority_set() and gnutls_priority_set_direct().
5923 ** Internal copy of OpenCDK upgraded to version 0.6.6.
5925 ** API and ABI modifications:

5954 gnutls_certificate_send_x509_rdn_sequence: ADD prototype to gnutls.h.in.
5956 * Version 2.1.6 (released 2007-11-15)
5958 ** Corrected bug in decompression of expanded compression data.
5960 ** Added the --to-p8 option to certtool to convert private keys
5963 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
5965 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
5968 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
5969 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
5970 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
5971 documented. This caused some problems (e.g., debian #450854). To
5972 avoid backwards compatibility problems, this release revert this
5973 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
5974 done in GnuTLS 2.0.x and earlier, and add a new error code
5975 GNUTLS_E_UNKNOWN_ALGORITHM.
5977 ** Fixes several gtk-doc warnings.
5979 ** API and ABI modifications:
5980 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
5981 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
5982 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
5984 * Version 2.1.5 (released 2007-11-01)
5986 ** Fix PKCS#3 parameter export problem.
5988 ** Improve certtool queries, they now print the default value.
5992 ** Update gnulib files.
5994 ** API and ABI modifications:
5995 No changes since last version.
5997 * Version 2.1.4 (released 2007-10-27)
5999 ** Added the --v1 option to certtool, to allow generating X.509
6000 version 1 certificates.
6002 ** certtool: Add option --disable-quick-random to enable the old behaviour
6003 of using /dev/random to generate keys.
6005 ** Added priority functions that accept strings.
6007 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
6008 priorities preferences.
6010 ** Added gnutls_record_disable_padding() to allow servers talking to
6011 buggy clients that complain if the TLS 1.0 record protocol padding is
6014 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
6015 all supported compatibility options (like disabling padding).
6017 ** The gnutls_certificate_set_openpgp_* functions were modified to include
6018 the format. This makes the interface consistent with the x509 functions.
6020 ** Internal copy of OpenCDK upgraded to version 0.6.5.
6022 ** Update gnulib files.

6059 * Version 2.1.3 (released 2007-10-17)
6061 ** TLS authorization support removed.
6062 This technique may be patented in the future, and it is not of crucial
6063 importance for the Internet community. After deliberation we have
6064 concluded that the best thing we can do in this situation is to
6065 encourage society not to adopt this technique. We have decided to
6066 lead the way with our own actions.
6068 ** Re-enabled the 256 bit ciphers in the default priorities.
6070 ** Corrected bugs in openpgp key verification using a keyring (both in

6083 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
6084 gnutls_supplemental_data_format_type_t enum type becomes empty.
6086 * Version 2.1.2 (released 2007-10-14)
6088 ** Removed all the trustdb code from openpgp authentication.
6089 We now use only the well-specified keyrings.
6091 ** The 256 bit ciphers are not enabled in the default priorities.
6093 ** Added support for DSA2 using libgcrypt 1.3.0.
6095 ** certtool: Fixed data corruption when using --outder.
6097 ** Removed all the xml related stubs and functions.

6100 by the server in order to adjust parameters before the handshake.
6102 ** SRP was corrected to adhere to the latest draft (published soon as RFC)
6104 ** Corrected bug which did not allow a server to run without supporting
6107 ** Updated the DN parser which now prints wrongly decoded values as hex

6128 * Version 2.1.1 (released 2007-09-24)
6130 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
6131 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
6132 compiled with Camellia support. See the libgcrypt documentation on
6133 how to enable it. Unconditionally disable it using the configure
6134 option --disable-camellia. Fixes #1.
6136 ** Properly document in the NEWS file the API change in the last release.
6138 ** API and ABI modifications:
6139 No changes since last version.
6141 * Version 2.1.0 (released 2007-09-20)
6143 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
6144 The support is disabled by default. Since no value has been allocated
6145 by the IANA for this extension yet, you will need to provide one
6146 yourself by invoking './configure --enable-opaque-prf-input=42'.
6149 ** Example code: Fix compilation flaw under MinGW.
6151 ** API and ABI modifications:
6152 gnutls_oprfi_callback_func: ADD, new typedef function prototype.

6185 ** TLS authorization support removed.
6186 This technique may be patented in the future, and it is not of crucial
6187 importance for the Internet community. After deliberation we have
6188 concluded that the best thing we can do in this situation is to
6189 encourage society not to adopt this technique. We have decided to
6190 lead the way with our own actions.
6192 ** certtool: Fixed data corruption when using --outder.
6194 ** Fix configure-time Guile detection.
6196 ** API and ABI modifications:
6197 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
6198 gnutls_supplemental_data_format_type_t enum type becomes empty.
6200 * Version 2.0.1 (released 2007-09-20)
6202 ** New directory doc/credentials/ with test credentials.
6203 This collects the test credentials from the web page and from src/.
6204 The script gnutls-http-serv has also been moved to that directory.
6206 ** Update SRP extension type and cipher suite with official IANA values.
6207 This breaks backwards compatibility with SRP in older versions of
6208 GnuTLS, but this is intentional to speed up the adoption of the
6209 official values. The old values we used were incorrect.
6211 ** Guile: Fix `x509-certificate-dn-oid'
6213 ** API and ABI modifications:
6214 No changes since last version.
6216 * Version 2.0.0 (released 2007-09-04)
6218 ** Included copy of Libtasn1 upgraded to version 1.1.
6220 ** Disable building of some examples if anonymous ciphers are disabled.
6222 ** Don't build examples for disabled features.
6224 ** API and ABI modifications:
6225 No changes since last version.
6227 * Version 1.7.19 (released 2007-08-27)
6229 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
6230 This solves connection problems in mutt, see
6231 <http://bugs.debian.org/439640>.
6233 ** Update gnulib files.
6234 In particular, the getpass module -- with its dependencies on getline,
6235 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
6236 library) directory to the gl/ directory (only used by the command line
6237 tools). The reason is that getpass is now only used by the
6238 command-line tools, and reducing the number of gnulib modules linked
6239 to the core library helps portability and reduces size.
6243 ** Disable building of PGP examples if PGP is disabled.
6245 ** Included copy of OpenCDK upgraded to version 0.6.4.
6247 ** API and ABI modifications:
6248 No changes since last version.
6250 * Version 1.7.18 (released 2007-08-16)
6252 ** Install images for the info manual.
6253 This has a side effect of renaming the images. See
6254 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
6255 discussions on the approach chosen.
6257 ** Fix pointer mix to variables of different size.
6258 Patch extracted from
6259 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
6261 ** Fix warnings during build.
6262 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
6264 ** API and ABI modifications:
6265 No changes since last version.
6267 * Version 1.7.17 (released 2007-08-15)
6269 ** New functions to perform external signing.
6270 Set the signing callback function (of the gnutls_sign_func prototype)
6271 using the gnutls_sign_callback_set function. In the callback, you may
6272 find the new functions gnutls_x509_privkey_sign_hash and
6273 gnutls_openpgp_privkey_sign_hash useful. A new function
6274 gnutls_sign_callback_get is also added, to retrieve the function
6275 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
6276 comments and testing.
6278 ** New self test of client and server authenticated X.509 TLS sessions.
6279 See tests/x509self.c and tests/x509signself.c. The latter also tests
6280 the new external signing callback interface.
6282 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
6283 These two actually describe the outer limits of a range of error codes
6284 reserved to the application. All of the errors are treated as fatal
6285 by the library (it has to since it doesn't know the semantics of the
6286 error codes). This can be useful in callbacks, to signal some
6287 application-specific error condition, which will usually eventually
6288 cause some gnutls API to return the same error code as the callback,
6289 which then can be inspected by the application. Note that error codes
6292 ** gnutls_set_default_priority now disable TLS 1.2 by default.
6293 The RFC is not released yet, and we're approaching a major release so
6294 let's not enable it just yet.
6296 ** Fix namespace so that gnutls_*_t is used consistently.
6297 Before, many places in the GnuTLS code used the old deprecated type
6298 names without the '_t' suffix.
6300 ** Build fixes for Guile code.
6301 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
6303 ** More documentation fixes.
6304 In particular, the section headings were modified for casing. By
6305 Ludovic Courtes <ludovic.courtes@laas.fr>.
6307 ** Updated Polish and Swedish translations.
6308 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
6309 <po@danielnylander.se>.
6311 ** API and ABI modifications:
6312 gnutls_sign_func: ADD, new type for sign callback.
6313 gnutls_sign_callback_set: ADD, new function to set sign callback.
6314 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
6315 gnutls_x509_privkey_sign_hash,
6316 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
6317 GNUTLS_E_APPLICATION_ERROR_MIN,
6318 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
6320 * Version 1.7.16 (released 2007-08-07)
6322 ** Fix sanity checks and return values in certificate selection.
6323 In some cases, GnuTLS omitted to report suitable error codes when no
6324 suitable certificate was found.
6326 ** Fix gnutls-cli starttls EOF on Mac OS X.
6327 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
6329 ** Documentation fixes.
6330 In particular, the section headings were modified for casing. By
6331 Ludovic Courtes <ludovic.courtes@laas.fr>.
6333 ** Update gnulib files.
6335 ** API and ABI modifications:
6336 No changes since last version.
6338 * Version 1.7.15 (released 2007-07-02)
6340 ** Fix self-tests key-id under mingw32.
6342 ** Test that the Guile header files are recent enough to work.
6343 Before we just tested that the command line tool 'guile' was recent
6344 enough, which may not be sufficient if you still have an old
6345 libguile.h header installed.
6347 ** Guile bindings are now installed under $prefix by default.
6348 Use --without-guile-site-dir to install it under $pkgdatadir/site/
6349 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
6350 Use --with-guile-site-dir=/your/own/path to specify the path manually.
6351 The default, --with-guile-site-dir, will install the Guile bindings
6352 under $datadir/guile/site. There is a new section 'Guile
6353 Preparations' in the manual that discuss these issues.
6355 ** Fix run-time library path ordering in linking the Guile bindings.
6357 ** Improved manual on downloading, installing, getting help, bug reports etc.
6358 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
6360 ** Add Malay message translations.
6361 Thanks to Sharuzzaman Ahmat Raslan <sharuzzaman@myrealbox.com>.
6363 ** API and ABI modifications:
6364 No changes since last version.
6366 * Version 1.7.14 (released 2007-06-26)
6368 ** Don't enable Guile bindings unless we have Guile 1.8 or later.
6369 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
6371 ** Fix memory leak during DSA signature verification.

6392 No changes since last version.
6394 * Version 1.7.13 (released 2007-06-11)
6396 ** OpenCDK copy updated to version 0.6.3.
6398 ** Build fixes for GnuTLS Guile bindings.
6399 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
6401 ** Build fix for GTK-DOC manual.
6403 ** Update gnulib files.
6405 ** API and ABI modifications:
6406 No changes since last version.
6408 * Version 1.7.12 (released 2007-06-08)
6410 ** Guile bindings for GnuTLS have been included.
6411 Contributed by Ludovic Courtès <ludovic.courtes@laas.fr>. There is a
6412 new chapter 'Guile Bindings' in the manual.
6414 ** Have PKCS8 parser return better error codes.
6415 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
6416 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
6417 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
6419 ** Fix mem leak for sessions with client authentication via certificates.
6420 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
6421 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
6424 Reported by Dennis Vshivkov <walrus@amur.ru>, see
6425 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333050>. Added
6426 self-test tests/parse_ca.c to test regressions.
6428 ** Fix build failures related to missing images in manual.
6429 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
6431 ** Update gnulib files.
6433 ** API and ABI modifications:
6434 No changes since last version.
6436 * Version 1.7.11 (released 2007-05-26)
6438 ** Include opencdk.h in the release.
6439 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
6441 ** API and ABI modifications:
6442 No changes since last version.
6444 * Version 1.7.10 (released 2007-05-25)
6446 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
6447 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
6449 ** Update of gnulib files.
6451 ** GnuTLS is now developed in GIT instead of CVS.
6452 See <http://repo.or.cz/w/gnutls.git> for a public repository.
6454 ** API and ABI modifications:
6455 gnutls_x509_crt_get_raw_issuer_dn: ADD.
6456 gnutls_x509_crt_get_raw_dn: ADD.
6458 * Version 1.7.9 (released 2007-05-12)
6460 ** X.509 certificates are preferred over OpenPGP keys.
6461 This is a change in the semantics of gnutls_set_default_priority.
6463 ** The included copy of OpenCDK has been updated to 0.6.1.
6464 There has been some API changes in OpenCDK, and the GnuTLS layer have
6465 been modified as well. Note that while there are API/ABI incompatible
6466 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
6467 its API/ABI have not changed. From this version on, GnuTLS requires
6468 OpenCDK 0.6.0 or later.
6470 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
6472 ** Change certtool's default serial number from 0 to a time-based value.
6474 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
6475 Before, we remove the parameters field, which resulted in a slightly
6476 different DER encoding which in turn caused signature verification
6477 failures of GnuTLS-generated RSA certificates in some other
6478 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
6479 you read, this may or may not be correct, but our new behaviour appear
6480 to be consistent with other widely used implementations.
6482 ** Fix mem leaks in gnutls_x509_crt_print.
6484 ** API and ABI modifications:
6485 No changes since last version.
6487 * Version 1.7.8 (released 2007-04-16)
6489 ** Added examples for the authorization extension.
6490 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
6492 ** The examples only use gnutls_set_default_priority().
6493 The exception is when DH_ANON is needed.
6495 ** Improve gnutls_set_default_priority() priorities.
6496 The new approach is for it to try and negotiate all secure and
6497 standard mechanisms available. Currently, DH_ANON ciphersuites and
6498 LZO compressions are not enabled by default, because they are,
6499 respectively, insecure and non-standardized. Note that TLS 1.2 will
6500 not be enabled by default in non-experimental release until it has
6501 been approved by the IETF.
6503 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
6504 This means that to get DH_ANON and LZO compression, you'll need to
6505 specify that manually using '--kx anon' or '--comp lzo'.
6507 ** Minor fixes to the human display format of X.509 certificates.
6509 ** New APIs to extract Distinguished Name's from X.509 certificates.
6510 Based on patch from Howard Chu <hyc@symas.com>.
6512 ** Improved library searching for opencdk.
6513 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
6514 The deprecated opencdk.m4 is no longer used.
6516 ** New APIs to list supported algorithms in the library.
6517 The APIs are gnutls_cipher_list, gnutls_mac_list,
6518 gnutls_compression_list, gnutls_protocol_list,
6519 gnutls_certificate_type_list, gnutls_kx_list, and
6520 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
6522 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
6524 ** New configure option --disable-tls-authorization to disable tls-authz.
6526 ** Fix prototype for `gnutls_psk_set_client_credentials'.
6527 The last parameter was renamed from 'flags' to 'format' and the type
6528 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
6529 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
6532 ** Fix allocation in gnutls_certificate_set_openpgp_key.
6533 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
6535 ** API and ABI modifications:
6536 gnutls_x509_dn_t: ADD.
6537 gnutls_x509_ava_st: ADD.
6538 gnutls_x509_crt_get_subject,
6539 gnutls_x509_crt_get_issuer: ADD.
6540 gnutls_x509_dn_get_rdn_ava: ADD.
6541 gnutls_cipher_list: ADD.
6542 gnutls_mac_list: ADD.
6543 gnutls_compression_list: ADD.
6544 gnutls_protocol_list: ADD.
6545 gnutls_certificate_type_list: ADD.
6546 gnutls_kx_list: ADD.
6547 gnutls_cipher_suite_info: ADD.
6549 * Version 1.7.7 (released 2007-02-22)
6551 ** Support for supplemental handshake messages and authorization data.
6552 Supplemental data is described in RFC 4680 and the authorization
6553 extensions in draft-housley-tls-authz-extns-07.
6555 ** Support for authorization data in gnutls-cli and gnutls-serv.
6556 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
6558 ** Fix for gnutls_x509_crt_check_hostname.
6559 Before it would have reported that the certificate matched a hostname
6560 when it did not have any dNSName or any CN field. Report and tiny
6561 patch from "Richard W.M. Jones" <rjones@redhat.com>.
6563 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
6564 Tests regressions of the bug, and several other features.
6566 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
6567 Before there were no support for iPAddress SAN's during comparison.
6569 ** New API to print information about CRL's.
6570 The function is gnutls_x509_crl_print.
6572 ** New API to extract signature value from CRL's.
6573 The function is gnutls_x509_crl_get_signature.
6575 ** Support for directoryName Subject Alternative Name's.
6576 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
6577 string in the provided buffer.
6579 ** Internal improvements to certtool.
6580 It uses gnutls_x509_crl_print to print CRL information. It uses some
6581 more gnulib modules to simplify error handling.
6583 ** API and ABI modifications:
6584 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
6585 gnutls_supplemental_data_format_type_t: ADD.
6586 gnutls_authz_data_format_type_t: ADD.
6587 gnutls_supplemental_get_name: ADD.
6588 gnutls_authz_recv_callback_func,
6589 gnutls_authz_send_callback_func: ADD, callback prototypes.
6590 gnutls_authz_enable: ADD.
6591 gnutls_authz_send_x509_attr_cert,
6592 gnutls_authz_send_saml_assertion,
6593 gnutls_authz_send_x509_attr_cert_url,
6594 gnutls_authz_send_saml_assertion_url: ADD.
6595 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
6596 gnutls_x509_crl_print: ADD.
6597 gnutls_x509_crl_get_signature: ADD.
6599 * Version 1.7.6 (released 2007-02-12)
6601 ** Support for 'otherName' Subject Alternative Names.
6602 The existing API gnutls_x509_crt_get_subject_alt_name may now return
6603 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
6604 To find out the otherName OID (necessary for proper parsing of the
6605 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
6606 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
6607 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
6608 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
6610 ** Certtool can print otherName SAN values for certificates.
6611 For known otherName OIDs (currently only id-on-xmppAddr as defined by
6612 RFC 3920), it will also print the name.
6614 ** Fix TLS 1.2 RSA signing in servers.
6615 Before it used the old-style MD5+SHA1 signature, but the TLS
6616 signatures should be normal PKCS#1 signatures. FYI, we use and
6617 require that DigestInfo parameters are present and NULL for TLS 1.2.
6619 ** Add APIs to access X.509 extensions sequentially.
6620 The existing APIs gnutls_x509_crt_get_extension_oid() and
6621 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
6622 inspect the extensions in the order defined by the certificate.
6624 ** Add API to extract signature value from X.509 certificates.
6625 The function is gnutls_x509_crt_get_signature.
6627 ** Fix crash when generating proxy certificates in batch mode.
6628 If you don't specify a proxy policy in batch mode, it will use
6631 ** Add API to print information about X.509 certificates.
6632 The function is gnutls_x509_crt_print.
6634 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
6635 One consequence of this is that the output syntax has changed
6636 slightly. Some more fields are printed.
6640 ** API and ABI modifications:
6641 gnutls_x509_crt_print: ADD
6642 gnutls_certificate_print_formats_t: ADD, new enum.
6643 gnutls_x509_crt_get_signature: ADD.
6644 gnutls_x509_crt_get_extension_data: ADD.
6645 gnutls_x509_crt_get_extension_info: ADD.
6646 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
6647 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
6648 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
6650 * Version 1.7.5 (released 2007-02-06)
6652 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
6655 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
6657 ** Fix --list output for gnutls-cli and gnutls-serv.
6658 Mention TLS1.2, SHA512 etc.
6660 ** Manual contains new section on setting up a test HTTP server.
6661 A server set up following those descriptions are available online via
6662 <http://www.gnutls.org/server.html>.
6664 ** Update of gnulib files.
6666 ** API and ABI modifications:
6667 No changes since last version.
6669 * Version 1.7.4 (released 2007-02-05)
6671 ** Support for RSA signing using SHA-256/384/512.
6672 A new self test "sha2" tries to build a long X.509 certificate chain
6673 testing all new hashes.
6675 ** The gnutls-serv tool now use static DH parameters if none are supplied.
6677 ** Discuss proxy certificates in the manual.
6679 ** Improve bibliographical citations in the manual.
6681 ** Update of gnulib files.
6683 ** Fix certtool template handling of pathLenConstraints.
6684 It now defaults to -1 instead of 0, which causes the field to be
6685 missing unless the template specify it.
6687 ** API and ABI modifications:
6690 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
6693 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
6694 GNUTLS_SIGN_RSA_SHA256,
6695 GNUTLS_SIGN_RSA_SHA384,
6696 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
6698 * Version 1.7.3 (released 2007-02-01)
6700 ** New option to certtool: --generate-proxy.
6701 This will generate a Proxy Certificate from an end entity certificate.
6702 Proxy Certificates are documented in RFC 3820. You will need to
6703 specify the proxy certificate's private key with --load-privkey, the
6704 user certificate with --load-certificate and the private key used to
6705 sign the new proxy certificate with --load-ca-privkey. Certtool will
6706 query for proxy path length and the policy language OID. Currently
6707 only OIDs that have an empty policy are supported (which includes the
6708 two OIDs defined by RFC 3820).
6710 ** Certtool --certificate-info now prints information for Proxy Certificates.
6711 Before the proxy extension was just printed as DER encoded data.
6713 ** New APIs to set proxy subject names and get/set proxy cert extension.
6715 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
6717 ** Added self-test to test for regressions of pathLenConstraint bug.
6718 Incidentally, this also test (some) other regressions or changes in
6719 the output from certtool --certificate-info.
6721 ** When certtool generates CA certificates, pressing enter on the path
6722 ** length constraint query will now remove the field.
6723 Before it set the path length constraint to 0, which is a rather poor
6726 ** Certtool now print times in UTC when printing certificate/CRL info.
6728 ** Add better fix to work around C++ compiler bug on Mac OS X.
6729 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
6731 ** Fix import of ASCII armored OpenPGP keys.
6732 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
6734 ** Update of gnulib files.
6736 ** API and ABI modifications:
6737 gnutls_x509_crt_set_proxy_dn: ADD.
6738 gnutls_x509_crt_set_proxy: ADD.
6739 gnutls_x509_crt_get_proxy: ADD.
6741 * Version 1.7.2 (released 2007-01-14)
6743 ** Certtool now print the value of the pathLenConstraints field for certs.
6745 ** Certtool now query for path length constraints when generating CA certs.
6746 For batch uses, the certtool configuration name is "path_len".
6747 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
6749 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
6750 The new functions gnutls_x509_crt_get_basic_constraints and
6751 gnutls_x509_crt_set_basic_constraints provide a superset of the
6752 functionality in the old gnutls_x509_crt_get_ca_status and
6753 gnutls_x509_crt_set_ca_status (respectively), but the old functions
6754 will continue to be supported.
6756 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
6757 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
6758 OpenCDK release with this patch will be made soon, which should bump
6759 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
6761 ** Certtool --to-p12 can now store more than one certificate in the blob.
6762 Before it could only store one certificate, but now it will read and
6763 store as many certificate there are from the --load-certificate file.
6764 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
6766 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
6767 In particular, the OpenPGP function variables are no longer part of
6768 the exported libgnutls interface, and no header files from
6769 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
6770 were never intended for non-internal purposes, and thus this does not
6771 imply a change in the external API/ABI.
6773 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
6774 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
6776 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
6777 Before these parameters were set to make GnuTLS build under mingw32,
6778 however, they appear to no longer be necessary.
6780 ** A minor fix to the C++ library to make it build.
6781 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
6783 ** Update of gnulib files.
6785 ** API and ABI modifications:
6786 gnutls_x509_crt_get_basic_constraints: ADD.
6787 gnutls_x509_crt_set_basic_constraints: ADD.
6788 cdk_pubkey_to_sexp: ADD (in opencdk).
6789 cdk_seckey_to_sexp: ADD (in opencdk).
6791 * Version 1.7.1 (released 2006-12-28)
6793 ** TLS 1.2 server side fix.
6794 The Certificate Request sent did not contain the list of supported
6795 hashes field, thus violating the protocol. It will now contain an
6796 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
6798 ** TLS 1.2 DSA signature verification fix.
6799 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
6801 ** Fix the list of trusted CAs that server's send to clients.
6802 Before, the list contained issuer DN's instead of subject DN's of the
6803 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
6805 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
6806 Also added a self-test in tests/certificate_set_x509_crl.c to test the
6807 function. Reported by Max Kellermann <max@duempel.org>.
6809 ** Encode UID fields in DN's as DirectoryString.
6810 Before GnuTLS encoded and parsed UID fields as IA5String. This was
6811 incorrect, it should have used DirectoryString. Now it will use
6812 DirectoryString for the UID field, but for backwards compatibility it
6813 will also accept IA5String UID's. Reported by Max Kellermann
6816 ** Improve out-of-sourcedir builds from CVS.
6817 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
6819 ** Bootstrap tools changed.
6820 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
6821 building GnuTLS from CVS. Libtool 1.5.22 is used.
6823 ** Fixed a syntax error in lib/gnutls.asn.
6824 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
6826 ** Added German translation of GnuTLS messages.
6828 ** Update of gnulib files.
6830 ** API and ABI modifications:
6831 No changes since last version.
6833 * Version 1.7.0 (released 2006-11-29)
6835 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
6836 The details is that the protocol priority set by
6837 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
6838 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
6840 ** Preliminary support for TLS 1.2.
6841 The client has been successfully tested against
6842 https://www.mikestoolbox.org:4433/.
6844 ** Anonself test now print a lot of debugging info, including TLS version.
6846 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
6848 ** Update of gnulib files.
6850 ** API and ABI modifications:
6851 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
6853 *** Pulled up from stable 1.6.x branch:
6855 ** Fix ./configure failure with non-GCC compilers.
6856 This fixes the following error message:
6857 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
6858 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
6860 * Version 1.6.3 (released 2007-05-26)
6862 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
6863 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
6864 from the 1.7.x branch, see
6865 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
6867 ** Have PKCS8 parser return better error codes.
6868 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
6869 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
6870 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
6872 ** Fix mem leak for sessions with client authentication via certificates.
6873 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
6874 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
6876 ** Fix building of 'tlsia' self test.
6877 Earlier some gcc are known to build tlsia linking to
6878 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
6879 the build directory, even though command line parameters look OK.
6880 Changing order of some parameters fixes it.
6882 ** API and ABI modifications:
6883 gnutls_x509_crt_get_raw_issuer_dn: ADD.
6884 gnutls_x509_crt_get_raw_dn: ADD.
6886 * Version 1.6.2 (released 2007-04-18)
6888 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
6889 Before, we remove the parameters field, which resulted in a slightly
6890 different DER encoding which in turn caused signature verification
6891 failures of GnuTLS-generated RSA certificates in some other
6892 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
6893 you read, this may or may not be correct, but our new behaviour appear
6894 to be consistent with other widely used implementations.
6896 ** Regenerate the PKIX ASN.1 syntax tree.
6897 For some reason, after changing the ASN.1 type of ldap-UID in the last
6898 release, the generated C file built from the ASN.1 schema was not
6899 refreshed. This can cause problems when reading/writing UID
6900 components inside X.500 Distinguished Names. Reported by devel
6901 <dev001@pas-world.com>.
6903 ** Updated translations.
6905 ** API and ABI modifications:
6906 No changes since last version.
6908 * Version 1.6.1 (released 2006-12-28)
6910 ** Fix the list of trusted CAs that server's send to clients.
6911 Before, the list contained issuer DN's instead of subject DN's of the
6912 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
6914 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
6915 Reported by Max Kellermann <max@duempel.org>.
6917 ** Encode UID fields in DN's as DirectoryString.
6918 Before GnuTLS encoded and parsed UID fields as IA5String. This was
6919 incorrect, it should have used DirectoryString. Now it will use
6920 DirectoryString for the UID field, but for backwards compatibility it
6921 will also accept IA5String UID's. Reported by Max Kellermann
6924 ** Fix ./configure failure with non-GCC compilers.
6925 This fixes the following error message:
6926 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
6927 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
6929 ** API and ABI modifications:
6930 No changes since last version.
6932 * Version 1.6.0 (released 2006-11-17)
6934 ** No changes since 1.5.5.
6935 The major changes compared to the 1.4.x branch are:
6937 *** A GnuTLS C++ library is part of the official distribution.
6938 Currently there are no examples or documentation, but hopefully this
6939 will change. See gnutlsxx.h for the API.
6941 *** Windows is a supported platform.
6942 There are, however, two know bugs. One is related to select() in
6943 command line tools (not, nota bene, in the library), the other is a
6944 problem with libgcrypt that causes delays. Help is needed to resolve
6945 those issues, so we feel we can't delay the release because of this.
6947 *** New APIs for custom push/pull function error reporting.
6948 The new APIs are gnutls_transport_set_errno and
6949 gnutls_transport_set_global_errno. See the release notes for version
6950 1.5.4 for more information.
6952 *** Self tests are run under valgrind, if available. See --disable-valgrind.
6954 * Version 1.5.5 (released 2006-11-16)
6956 ** Correctly bump shared library version after adding new APIs.
6957 This was forgotten in the last release.
6959 ** Fix unsigned vs signed problem in ex-x509-info.c example.
6960 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
6962 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
6964 ** Update of gnulib files.
6966 ** API and ABI modifications:
6967 No changes since last version.
6969 * Version 1.5.4 (released 2006-11-07)
6971 ** New API functions to set errno in push/pull functions.
6972 Under Windows, setting the errno variable in a push/pull replacement
6973 may end up setting the wrong errno variable, and GnuTLS send/recv
6974 functions become confused about the real errno returned from a failed
6975 push/pull function. Therefor, we have added two APIs to set the errno
6976 variable used by GnuTLS. The APIs can also help to keep things
6977 thread-safe, by avoiding potentially global variables. Typically,
6978 instead of setting errno in your push/pull function, you will call one
6979 of these functions. It is recommended to use
6980 gnutls_transport_set_errno, but if you don't have the session variable
6981 easily accessible in the push/pull replacement function, you can use
6982 gnutls_transport_set_global_errno. Suggested by Tim Kosse
6983 <tim.kosse@filezilla-project.org>.
6985 void gnutls_transport_set_errno (gnutls_session_t session, int err);
6986 void gnutls_transport_set_global_errno (int err);
6988 ** When calling `recv' or `send' Windows errors are handled properly.
6989 The Windows recv/send functions doesn't use errno, and GnuTLS now use
6990 WSAGetLastError to access the error condition instead.
6992 ** Several OpenPGP API fixes.
6993 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
6994 important fix is to change the return value of
6995 gnutls_openpgp_privkey_get_pk_algorithm and
6996 gnutls_openpgp_key_get_pk_algorithm from 'int' to
6997 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
6998 compatible with 'int').
7000 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
7001 ** version, try to negotiate the highest version support by the GnuTLS server,
7002 ** instead of the lowest.
7003 Reported by <Pasi.Eronen@nokia.com>.
7005 ** Replace old constructs with use of gnulib modules.
7006 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
7007 the code. If the headers doesn't exist on the target system, gnulib
7008 will make sure its replacement header files are used instead.
7010 ** Fix SOVERSION computation for *.def files.
7011 This fixes build errors similar to "No rule to make target
7012 `libgnutls-`expr', needed by `all-am'." when building for Windows.
7014 ** gnutls_check-version uses strverscmp from gnulib.
7016 ** Update of gnulib files.
7018 ** API and ABI modifications:
7019 gnutls_transport_set_errno: ADD
7020 gnutls_transport_set_global_errno: ADD
7022 * Version 1.5.3 (released 2006-10-26)
7024 ** Add new self-test of RSA-MD5 signature chains.
7025 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
7026 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
7027 and is based on the work by Marc Stevens et al, see
7028 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
7030 ** Re-factor self tests.
7032 ** The include copy of Libtasn1 is updated to version 0.3.7.
7034 ** The included copy of OpenCDK is updated to version 0.5.11.
7036 ** Fix the filename of the *.def file on Windows after library version bump.
7038 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
7039 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
7040 gnulib modules. Earlier we could only use the LGPL'ed module from
7041 gnulib, because two gnulib directories in the same project didn't
7044 ** API and ABI modifications:
7045 No changes since last version.
7047 * Version 1.5.2 (released 2006-10-03)
7049 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
7050 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
7051 shared library version than this version, so you'll have to remove
7052 them and possibly relink your applications. The reason for this is
7053 that no API/ABI changes have been made since the 1.4.x branch, and
7054 that incrementing the shared library version was a mistake. Reported
7055 by Andreas Metzler <ametzler@downhill.at.eu.org>.
7057 ** Fix off-by-one error when computing length to malloc.
7058 The code is used by gnutls_openpgp_add_keyring_file and
7059 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
7060 <agl@imperialviolet.org>.
7062 ** Add version script for the GnuTLS C++ library.
7063 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
7065 ** Fix the C++ compiler detection logic.
7066 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
7068 ** Update of gnulib files.
7070 ** API and ABI modifications:
7071 No changes since last version.
7073 * Version 1.5.1 (released 2006-09-21)
7075 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
7076 ** Crypto 06 rump session attack.
7077 In particular, we check that the digestAlgorithm.parameters field is
7078 missing or empty, to avoid that it can contain "garbage" that may be
7079 used to alter the numeric properties of the signature. See
7080 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
7081 not exactly the same as the problem we fix here). Reported by Yutaka
7082 OIWA <y.oiwa@aist.go.jp>.
7084 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
7085 up to date information.
7087 ** Add self test to test for above flaw.
7089 ** Fix gnutls-cli-debug regarding resume support detection.
7090 Earlier, if the session-id from the server had a length of 0, it would
7091 indicate that the server supports resumption, which isn't the case.
7092 Reported by Kataja Kai <kai.kataja@op.fi>.
7094 ** Fix building of examples on FreeBSD by including netinet/in.h.
7095 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
7097 ** Fix certtool bug that caused the private key to not be loaded when
7098 generating a certificate with --load-request, which in turn triggered
7099 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
7100 by Sascha Ziemann <sascha.ziemann@secunet.com>.
7102 ** gnutls-cli and gnutls-serv works on Windows.
7103 The problem was the select() call that doesn't work on file
7104 descriptors (stdin) on Windows. We borrowed some code from plibc to
7105 solve this. It appears to be somewhat unreliable though.
7107 ** Autoconf 2.60 is now used.
7109 ** API and ABI modifications:
7110 No changes since last version.
7112 * Version 1.5.0 (released 2006-08-13)
7114 ** Change SRP and Cert-Type extensions to match IANA registry.
7116 ** Fixed bug in OpenPGP authentication handshake.
7118 ** Improvements for building under MinGW.
7119 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
7120 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
7121 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
7122 at run-time from ws2_32.dll, and falls back on a simple replacement if
7123 it is not available. Builds the library with -mms-bitfields
7124 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
7125 create *.def files, which are installed.
7127 ** The examples now (conditionally) include config.h and link to gnulib.
7128 No other source changes were necessary, so the examples should
7129 continue to be possible to use stand-alone without any autoconf or
7132 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
7133 You may unconditionally disable it with --disable-cxx. See
7134 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
7137 ** Made command line tool '--version' behave according to GNU Standards.
7138 This enables 'make distcheck' to succeed.
7140 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
7142 ** Make --without-included-libtasn1 work.
7143 Reported by Daniel Black <dragonheart@gentoo.org>.
7145 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
7146 See http://www.gnu.org/software/gnutls/security.html regardging
7147 GNUTLS-SA-2006-2 for more up to date information. Reported by
7148 satyakumar <satyam_kkd@hyd.hellosoft.com>.
7150 ** API and ABI modifications:
7151 No changes since last version.
7153 * Version 1.4.5 (released 2006-11-06)
7155 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
7156 ** version, try to negotiate the highest version support by the GnuTLS server,
7157 ** instead of the lowest.
7158 Reported by <Pasi.Eronen@nokia.com>.
7160 ** Fix typo in doc/examples/ex-serv-pgp.c.
7161 Reported by Adam Langley" <agl@imperialviolet.org>.
7163 ** API and ABI modifications:
7164 No changes since last version.
7166 * Version 1.4.4 (released 2006-09-12)
7168 ** Relax the test that caught signatures that exploit the variant of
7169 ** Bleichenbacher's Crypto 06 rump session attack on our
7170 ** verification logic flaw.
7171 In particular, we now permit the digestAlgorithm.parameters field to
7172 be present but empty, whereas in 1.4.3 we actually checked that the
7175 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
7176 The messages are only printed in debug mode, which is not recommended
7177 for normal use, and thus logging this situation cannot be abused as an
7178 oracle in typical recommended situations.
7180 ** API and ABI modifications:
7181 No changes since last version.
7183 * Version 1.4.3 (released 2006-09-08)
7185 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
7186 ** Crypto 06 rump session attack.
7187 In particular, we check that the digestAlgorithm.parameters field is
7188 empty, to avoid that it can contain "garbage" that may be used to
7189 alter the numeric properties of the signature. See
7190 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is

7206 ** API and ABI modifications:
7207 No changes since last version.
7209 * Version 1.4.2 (released 2006-08-12)
7211 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
7212 This can happen if you call gnutls_certificate_verify_peers2 and have
7213 a certain mix of local CA certificates and the peer send special
7214 certificates, that together trigger certain behaviour. It is not
7215 known at this point whether the crash can be triggered without the
7216 special local CA certificate, and thus turn this into a remote crash
7217 of clients that verify server certificates when they talk to a server
7218 with the special server certificate. See GNUTLS-SA-2006-2 on
7219 http://www.gnu.org/software/gnutls/security.html for more up to date
7220 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
7222 ** Change SRP and Cert-Type extensions to match IANA registry.
7224 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
7226 ** Make --without-included-libtasn1 work.
7227 Reported by Daniel Black <dragonheart@gentoo.org>.
7229 ** API and ABI modifications:
7230 No changes since last version.
7232 * Version 1.4.1 (released 2006-06-14)
7234 ** Replaced inactive ifdefs to enable openpgp support in test programs.
7236 ** Fixed bug in OpenPGP authentication handshake.
7238 ** Fixed typographical in man pages.
7240 ** Build fixes of the manual.
7242 ** Added Swedish translation.
7244 ** API and ABI modifications:
7245 No changes since last version.
7247 * Version 1.4.0 (released 2006-05-15)
7249 ** Remove GnuTLS 0.8.x compatibility functions.
7251 ** The libgcrypt RNG is initialized in gnutls_global_init().
7253 ** TLS/IA API changes from Emile van Bergen.
7254 A dummy credential structure is not needed now, if you wish to use the
7255 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
7258 ** The self-tests are now run under valgrind, if it is installed.
7260 ** Libtasn1 is updated to 0.3.4, and that version is now required.
7262 ** The command line tools now use getaddrinfo and support IPv6.
7264 ** API and ABI modifications:
7265 _gnutls_x509_get_raw_crt_activation_time,
7266 _gnutls_x509_get_raw_crt_expiration_time: Removed.
7267 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
7268 gnutls_ia_enable: Added.
7270 * Version 1.3.5 (released 2006-03-08)
7272 ** Error messages are now translated using GNU Gettext.
7274 ** The function gnutls_x509_crt_to_xml now return an internal error.
7275 This means that the code to convert X.509 certificates to XML format
7276 does not work any more. The reason is that the function called
7277 libtasn1 internal functions. It seems unclean for libtasn1 to export
7278 the APIs needed here. Instead it would be better to implement XML
7279 support inside libtasn1 properly. If you need this functionality
7280 strongly, please consider looking into implementing this suggested
7281 approach instead. As a workaround, you may also modify lib/x509/xml.c
7282 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
7284 ** Libraries are now built with libtool's -no-undefined.
7285 This helps producing libraries for Windows using mingw32.
7287 ** Doc fixes to explain that gnutls_record_send can block.
7289 ** Libtasn1 0.3.1 or later is now required.
7290 The include copy has been updated too.
7292 ** gnutls-cli can now recognize services and port numbers with the -p option.
7294 ** API and ABI modifications:
7295 No changes since last version.
7297 * Version 1.3.4 (released 2006-02-09)
7299 ** Fix read of out bounds bug in DER parser.
7300 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
7301 Protover SSL. Libtasn1 0.2.18 is now required, which contains the

7307 prevent future writes. That is to allow reading the already received data.
7308 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
7310 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
7311 gnutls_certificate_set_x509_trust(), that caused memory corruption if
7312 more than one certificates were added. Report and patch by Max Kellermann.
7314 ** Fix build problems of OpenCDK on AIX.
7315 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
7317 ** API and ABI modifications:
7318 No changes since last version.
7320 * Version 1.3.3 (released 2006-01-12)
7322 ** New API to access the TLS master secret.
7323 When possible, you should use the TLS PRF functions instead.
7324 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
7326 ** Improved handling when multiple libraries use GnuTLS at the same time.
7327 Now gnutls_global_init() can be called multiple times, and
7328 gnutls_global_deinit() will only deallocate the structure when it has
7329 been called as many times as gnutls_global_init() was called.
7331 ** Added a self test of TLS resume functionality.
7333 ** Fix crash in TLS resume code, caused by TLS/IA changes.
7335 ** Documentation fixes about thread unsafety, prompted by
7336 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
7337 In particular, gnutls_global_init() and gnutls_global_deinit() are not
7338 thread safe. Careful callers may want to protect the call using a
7339 mutex. The problem could also be ignored, which would cause a memory
7340 leak under rare conditions when two threads invoke the function
7341 roughly at the same time.
7343 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
7345 ** The code was indented again, including the external header files.
7347 ** API and ABI modifications:
7348 New functions to retrieve the master secret value:
7349 gnutls_session_get_master_secret
7351 Add a 'const' keyword to existing API:
7352 gnutls_x509_crq_get_challenge_password
7354 * Version 1.3.2 (released 2005-12-15)
7356 ** GnuTLS now support TLS Inner application (TLS/IA).
7357 This is per draft-funk-tls-inner-application-extension-01. This
7358 functionality is added to libgnutls-extra, so it is licensed under the
7359 GNU General Public License.
7361 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
7362 The PRF is used by some protocols building on TLS, such as EAP-PEAP
7363 and EAP-TTLS. One function to access the raw PRF and one to access
7364 the PRF seeded with the client/server random fields are provided.
7365 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
7367 ** New APIs to acceess the client and server random fields in a session.
7368 These fields can be useful by protocols using TLS. Note that these
7369 fields are typically used as input to the TLS PRF, and if this is your
7370 intended use, you should use the TLS PRF API that use the
7371 client/server random field directly. Suggested by Jouni Malinen
7372 <jkmaline@cc.hut.fi>.
7374 ** Internal type cleanups.
7375 The uint8, uint16, uint32 types have been replaced by uint8_t,
7376 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
7377 correct types on platforms that lack them. The uint type have been
7378 replaced by unsigned.
7380 ** API and ABI modifications:
7381 New functions to invoke the TLS Pseudo-Random-Function (PRF):
7385 New functions to retrieve the session's client and server random values:
7386 gnutls_session_get_server_random
7387 gnutls_session_get_client_random
7389 New function, to perform TLS/IA handshake:
7392 New function to decide whether to do a TLS/IA handshake:
7393 gnutls_ia_handshake_p
7395 New functions to allocate a TLS/IA credential:
7396 gnutls_ia_allocate_client_credentials
7397 gnutls_ia_free_client_credentials
7398 gnutls_ia_allocate_server_credentials
7399 gnutls_ia_free_server_credentials
7401 New functions to handle the AVP callback:
7402 gnutls_ia_set_client_avp_function
7403 gnutls_ia_set_client_avp_ptr
7404 gnutls_ia_get_client_avp_ptr
7405 gnutls_ia_set_server_avp_function
7406 gnutls_ia_set_server_avp_ptr
7407 gnutls_ia_get_server_avp_ptr
7409 New functions, to toggle TLS/IA application phases:
7410 gnutls_ia_require_inner_phase
7412 New function to mix session keys with inner secret:
7413 gnutls_ia_permute_inner_secret
7415 Low-level API (used internally by gnutls_ia_handshake):
7416 gnutls_ia_endphase_send
7420 New functions that can be used after successful TLS/IA negotiation:
7421 gnutls_ia_generate_challenge
7422 gnutls_ia_extract_inner_secret
7424 Enum type with TLS/IA modes:
7427 Enum type with TLS/IA packet types:
7430 Enum values for TLS/IA alerts:
7431 GNUTLS_A_INNER_APPLICATION_FAILURE
7432 GNUTLS_A_INNER_APPLICATION_VERIFICATION
7434 New error codes, to signal when an application phase has finished:
7435 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
7436 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
7438 New error code to signal TLS/IA verify failure:
7439 GNUTLS_E_IA_VERIFY_FAILED
7441 * Version 1.3.1 (released 2005-12-08)
7443 ** Support for DHE-PSK cipher suites has been added.
7444 This method offers perfect forward secrecy.
7446 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
7447 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
7449 ** Corrected a bug in certtool for 64 bit machines. Reported
7450 by Max Kellermann <max@duempel.org>.
7452 ** New function to set a X.509 private key and certificate pairs, and/or
7453 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
7454 <emile@e-advies.nl>.
7456 The integrity of the PKCS#12 file is protected through a password
7457 based MAC; public-key based signatures for integrity protection are
7458 not supported. PKCS#12 bags may be encrypted using password derived
7459 symmetric keys, public-key based encryption is not supported. The
7460 PKCS#8 keys may be encrypted using passwords. The API use the same
7461 password for all operations. We believe that any more flexibility
7462 create too much complexity that would hurt overall security, but may
7463 add more PKCS#12 related APIs if real-world experience indicate
7466 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
7467 reported by Emile van Bergen <emile@e-advies.nl>.
7468 This will enable "certtool -k -8" to parse those keys.
7470 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
7471 Use "certtool -p -8" and press press enter at the prompt. Earlier,
7472 certtool would have encrypted the key using an empty password.
7474 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
7475 Earlier it would have prompted the user for it, even if --password was
7478 ** Added self test of PKCS#8 parsing.
7479 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
7480 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
7483 ** API and ABI modifications:
7484 New function to set X.509 credentials from a PKCS#12 file:
7485 gnutls_certificate_set_x509_simple_pkcs12_file
7487 New gnutls_kx_algorithm_t enum type:
7490 New API to return session data (basically same as gnutls_session_get_data):
7491 gnutls_session_get_data2
7493 New API to set PSK Diffie-Hellman parameters:
7494 gnutls_psk_set_server_dh_params
7496 * Version 1.3.0 (2005-11-15)
7498 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
7499 This add several new APIs, see below. Read the updated manual for
7500 more information. A new self test "pskself" has been added, that will
7501 test this functionality.
7503 ** The session resumption data are now system independent.
7505 ** The code has been re-indented to conform to the GNU coding style.
7507 ** Removed the RIPEMD ciphersuites.
7509 ** Added a discussion of the internals of gnutls in manual.
7511 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
7513 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
7515 ** Make sure config.h is included first in a few files, from Albert Chin.
7517 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
7519 ** Don't install SRP programs and man pages if --disable-srp-authentication,
7522 ** API and ABI modifications:
7523 New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK
7525 New gnutls_credentials_type_t credential type:
7528 New credential types:
7529 gnutls_psk_server_credentials_t
7530 gnutls_psk_client_credentials_t
7532 New functions to allocate PSK credentials:
7533 gnutls_psk_allocate_client_credentials
7534 gnutls_psk_free_client_credentials
7535 gnutls_psk_free_server_credentials
7536 gnutls_psk_allocate_server_credentials
7538 New enum type for PSK key flags:
7539 gnutls_psk_key_flags
7541 New function prototypes for credential callback:
7542 gnutls_psk_client_credentials_function
7543 gnutls_psk_server_credentials_function
7545 New function to set PSK username and key:
7546 gnutls_psk_set_client_credentials
7548 New function to set PSK passwd file:
7549 gnutls_psk_set_server_credentials_file
7551 New function to extract PSK user in server:
7552 gnutls_psk_server_get_username
7554 New functions to set PSK callback:
7555 gnutls_psk_set_server_credentials_function
7556 gnutls_psk_set_client_credentials_function
7558 Use size_t instead of int for output size parameter:
7559 gnutls_srp_base64_encode
7560 gnutls_srp_base64_decode
7562 * Version 1.2.11 (2006-05-11)
7563 - The function gnutls_x509_crt_to_xml is not supported any more, and
7564 return an internal error. The reason is that the function called
7565 internal libtasn1 functions which are no longer exported from
7567 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
7568 - Updated gnulib compatibility files.
7569 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
7570 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
7571 - API and ABI modifications:
7572 No changes since last version.
7574 * Version 1.2.10 (2006-02-09)
7575 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
7576 <admin@gleg.net>, and debugging help from Protover SSL.
7577 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
7578 The included version has been updated too.
7579 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
7580 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
7581 - Corrected a bug in certtool for 64 bit machines. Reported
7582 by Max Kellermann <max@duempel.org>.
7583 - Corrected bugs in gnutls_certificate_set_x509_crl() and
7584 gnutls_certificate_set_x509_trust(), that caused memory corruption if
7585 more than one certificates were added. Report and patch by Max Kellermann.
7586 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
7587 longer invalidate a session if the underlying send fails, but it will
7588 prevent future writes. That is to allow reading the already received data.
7589 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
7591 * Version 1.2.9 (2005-11-07)
7592 - Documentation was updated and improved.
7593 - RSA-MD2 is now supported for verifying digital signatures.
7594 - Due to cryptographic advances, verifying untrusted X.509
7595 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
7596 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
7597 applications that must remain interoperable, you can use the
7598 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
7599 flags when verifying certificates. Naturally, this is not
7600 recommended default behaviour for applications. To enable the
7601 broken algorithms, call gnutls_certificate_set_verify_flags with the
7602 proper flag, to change the verification mode used by
7603 gnutls_certificate_verify_peers2.
7604 - Make it possible to send empty data through gnutls_record_send,
7605 to align with the send(2) API.
7606 - Some changes in the certificate receiving part of handshake to prevent
7607 some possible errors with non-blocking servers.
7608 - Added numeric version symbols to permit simple CPP-based feature
7609 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
7610 - The (experimental) low-level crypto alternative to libgcrypt used
7611 earlier (Nettle) has been replaced with crypto code from gnulib.
7612 This leads to easier re-use of these components in other projects,
7613 leading to more review and simpler maintenance. The new configure
7614 parameter --with-builtin-crypto replace the old --with-nettle, and
7615 must be used if you wish to enable this functionality. See README
7616 under "Experimental" for more information. Internally, GnuTLS has
7617 been updated to use the new "Generic Crypto" API in gl/gc.h. The
7618 API is similar to the old crypto/gc.h, because the gnulib code were
7619 based on GnuTLS's gc.h.
7620 - Fix compiler warning in the "anonself" self test.
7621 - API and ABI modifications:
7622 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
7623 This doesn't reflect a change in behaviour,
7624 so we don't break backwards compatibility.
7625 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
7626 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
7627 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
7628 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
7630 gnutls_x509_crt_list_verify,
7631 gnutls_x509_crt_verify, or
7632 gnutls_certificate_set_verify_flags.
7633 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
7634 used when broken signature algorithms
7635 is used (currently RSA-MD2/MD5).
7636 LIBGNUTLS_VERSION_MAJOR,
7637 LIBGNUTLS_VERSION_MINOR,
7638 LIBGNUTLS_VERSION_PATCH,
7639 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
7640 version number, can be used for feature existence
7643 * Version 1.2.8 (2005-10-07)
7644 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
7645 - Don't install the auxilliary libexamples library used by the
7646 examples in doc/examples/ on "make install", report and tiny patch
7647 from Thomas Klausner <tk@giga.or.at>.
7648 - If you pass a X.509 CA or PGP trust database to the command line
7649 tool, it will now abort the connection if the server certificate
7650 validation fails. Use the parameter --insecure to continue even
7651 after certificate validation failures. Inspired from discussion
7652 with Alexander Kotelnikov <sacha@myxomop.com>.
7653 - The test for socklen_t has been moved to gnulib.
7654 - Link failures for duplicate or missing "program_name" symbol has been fixed,
7655 patch from Martin Lambers <marlam@marlam.de>.
7656 - The command line tool and the examples no longer uses mmap or bzero,
7657 to make them more portable, patch from Martin Lambers
7659 - Made the PKCS #12 API handle null passwords. Based on patch by
7660 Anton Altaparmakov <aia21@cam.ac.uk>.
7661 - The GTK-DOC manual should build with current released tools.
7662 (But a copy of the output is included, so the tools are not required.)
7663 - The inet_ntop function is now used through gnulib.
7664 - API and ABI modifications:
7665 No changes since last version.
7667 * Version 1.2.7 (2005-09-09)
7668 - The GnuTLS and GnuTLS-extra libraries are now built with versioned symbols.
7669 - Certtool now complains when reading out-of-range X.509 serial
7670 numbers, suggested by Fran <e_agf@yahoo.es>.
7671 - Certtool now uses the readline library (when available) when reading
7672 X.509 serial numbers.
7673 - Fixed build problems in getpass on uClibc and Mingw32 platforms.
7674 - Fixed compile warning regarding socklen_t on Mingw32, reported by
7675 Martin Lambers <marlam@marlam.de>.
7676 - Fixed examples in doc/examples/, suggested by Fran <e_agf@yahoo.es>.
7677 - Gnulib is now used for the core library, enabling future code cleanups.
7678 - The gnutls-cli tool now use gnutls_certificate_verify_peers2,
7679 suggested by Daniel Stenberg <daniel@haxx.se>.
7680 - Doc fixes for gnutls_transport_set_push and gnutls_transport_set_pull.

7688 - MiniLZO updated to version 2.01 and moved to separate directory.
7689 - Collision between system LZO header files and MiniLZO header file
7690 fixed, reported by Matthias Urlichs <smurf@smurf.noris.de>.
7691 - Will now test for liblzo functionality in liblzo2 too, reported by
7692 Thomas Klausner <tk@giga.or.at>.
7693 - Minilibtasn1 is now 0.2.14 (no code changes).
7694 - Some code changes to avoid GTK-DOC warnings.
7695 - API and ABI modifications:
7696 No changes since last version.
7698 * Version 1.2.5 (2005-07-03)
7699 - More builddir != srcdir fixes, reported by Mike Castle
7700 <dalgoda@ix.netcom.com>.
7701 - Fixed off-by-one bug in the size parameter of gnutls_x509_crt_get*_dn,
7702 reported by Adam Langley <alangley@gmail.com>.
7703 - Corrected some stuff in minilzo detection. Pointed out by
7705 - MiniLZO updated to version 2.00.
7706 - gnutls_x509_crt_list_import now accept a DER formatted CRL.
7707 - API and ABI modifications:
7708 No changes since last version.
7710 * Version 1.2.4 (2005-05-28)
7711 - Corrected some bugs that could affect 64 bit systems.
7712 - Some corrections in the header files to include the prototype
7713 of memmem properly (affected 64 bit systems). Report and patch
7714 by Yoann Vandoorselaere <yoann@prelude-ids.org>.
7715 - Introduced the --fix-key option to certtool, which can be used to
7716 regenerate the (optional) parameters in a private key. It should
7717 be used together with --key-info.
7718 - Corrected a bug in certificate chain verification that could lead
7719 to marking a trusted chain as non trusted, if the last certificate in
7720 the chain was a self signed one.
7721 - Gnulib portability files were updated.
7722 - License were updated to reflect new FSF address.
7723 - API and ABI modifications:
7724 No changes since last version.
7726 * Version 1.2.3 (2005-04-28)
7727 - Corrected bug in record packet parsing that could lead
7728 to a denial of service attack.
7729 - Corrected bug in RSA key export. Previously exported keys
7730 can be fixed using certtool. Use certtool -k <infile >outfile
7731 - API and ABI modifications:
7732 gnutls_x509_privkey_fix(): Add.
7734 * Version 1.2.2 (2005-04-25)
7735 - gnutls_error_to_alert() now considers
7736 GNUTLS_E_UNEXPECTED_HANDSHAKE_PACKET.
7737 - Fixed error in session resuming that could cause a crash in a session.
7738 - Fixed pkcs12 friendly name and local key identifier decoding.
7739 - Internal cleanups, removed duplicate typedef/struct definitions,
7740 and made source code include external include file, to check
7741 function prototypes during compile time.
7742 - API and ABI modifications:
7743 No changes since last version. At least not intentional, but due
7744 to the include header changes, there may be inadvertant changes,
7745 please let us know if you find any.
7747 * Version 1.2.1 (2005-04-04)
7748 - gnutls_bye() will no longer fail when RDWR is used and application
7749 data are available for reading.
7750 - Added more strict checks for the SRP parameters (g,n), when they
7751 are not in the included list.
7752 - Added warning to certtool when MD5 is being used for digital
7754 - Optimizations ("-O2 -finline-functions") are not enabled by default,
7755 instead the standard autoconf defaults are used. Use `./configure
7756 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
7757 - Added the option --get-dh-params to certtool, in order to get the
7758 parameters included in the library primes and generators.
7759 - Improved the semantics of GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT, to
7760 allow only trusted Version 1 CAs and introduced
7761 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT which has the old semantics.
7762 - Nettle self tests now build properly, reported by Pierre
7763 <pierre42d@9online.fr>.
7764 - Eliminated some memory leaks in DHE and RSA-EXPORT cipher suites.
7765 Reported by Yoann Vandoorselaere <yoann@prelude-ids.org>.
7766 - If the library has been compiled with features disabled, a warning is
7767 issued during the compilation of any program.
7768 - API and ABI modifications:
7769 gnutls_x509_crt_list_import(): Add
7770 gnutls_x509_crq_get_attribute_by_oid(): Add.
7771 gnutls_x509_crq_set_attribute_by_oid(): Add
7772 gnutls_x509_crt_set_extension_by_oid(): Add.
7773 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT: Modify semantics.
