10 * The following bugs are resolved with this release:
12 15347, 15804, 15894, 16002, 16198, 16284, 16357, 16447, 16532, 16545,
13 16574, 16599, 16600, 16609, 16610, 16611, 16613, 16623, 16632, 16634,
14 16639, 16642, 16649, 16670, 16674, 16677, 16680, 16683, 16689, 16695,
15 16701, 16706, 16707, 16712, 16713, 16714, 16731, 16743, 16758, 16760.
17 * Running the testsuite no longer terminates as soon as a test fails.
18 Instead, a file tests.sum (xtests.sum from "make xcheck") is generated,
19 with PASS or FAIL lines for individual tests. A summary of the results is
20 printed, including a list of failing lists, and "make check" exits with
21 error status if there were any unexpected failures. "make check
22 stop-on-test-failure=y" may be used to keep the old behavior.
24 * The am33 port, which had not worked for several years, has been removed
27 * The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
28 supported; they now act the same as _DEFAULT_SOURCE (but generate a
29 warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that
30 conflicted with POSIX (support for which was removed in 2.19), the
31 interfaces those macros enabled remain available when compiling with
32 _GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
37 * The following bugs are resolved with this release:
39 156, 387, 431, 762, 832, 926, 2801, 4772, 6786, 6787, 6807, 6810, 6981,
40 7003, 9721, 9954, 10253, 10278, 11087, 11157, 11214, 12100, 12486, 12751,
41 12986, 13028, 13982, 13985, 14029, 14032, 14120, 14143, 14155, 14286,
42 14547, 14699, 14752, 14782, 14876, 14910, 15004, 15048, 15073, 15089,
43 15128, 15218, 15268, 15277, 15308, 15362, 15374, 15400, 15425, 15427,
44 15483, 15522, 15531, 15532, 15593, 15601, 15608, 15609, 15610, 15632,
45 15640, 15670, 15672, 15680, 15681, 15723, 15734, 15735, 15736, 15748,
46 15749, 15754, 15760, 15763, 15764, 15797, 15799, 15825, 15843, 15844,
47 15846, 15847, 15849, 15850, 15855, 15856, 15857, 15859, 15867, 15886,
48 15887, 15890, 15892, 15893, 15895, 15897, 15901, 15905, 15909, 15915,
49 15917, 15919, 15921, 15923, 15939, 15941, 15948, 15963, 15966, 15968,
50 15985, 15988, 15997, 16032, 16034, 16036, 16037, 16038, 16041, 16046,
51 16055, 16071, 16072, 16074, 16077, 16078, 16103, 16112, 16143, 16144,
52 16146, 16150, 16151, 16153, 16167, 16169, 16172, 16195, 16214, 16245,
53 16271, 16274, 16283, 16289, 16293, 16314, 16316, 16330, 16337, 16338,
54 16356, 16365, 16366, 16369, 16372, 16375, 16379, 16381, 16384, 16385,
55 16386, 16387, 16390, 16394, 16398, 16400, 16407, 16408, 16414, 16430,
56 16431, 16453, 16474, 16506, 16510, 16529
58 * Slovenian translations for glibc messages have been contributed by the
59 Translation Project's Slovenian team of translators.
61 * The public headers no longer use __unused nor __block. This change is to
62 support compiling programs that are derived from BSD sources and use
63 __unused internally, and to support compiling with Clang's -fblock
64 extension which uses __block.
66 * CVE-2012-4412 The strcoll implementation caches indices and rules for
67 large collation sequences to optimize multiple passes. This cache
68 computation may overflow for large collation sequences and may cause a
69 stack or buffer overflow. This is now fixed to use a slower algorithm
70 which does not use a cache if there is an integer overflow.
72 * CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
73 rules for large collation sequences to optimize multiple passes and falls
74 back to alloca if malloc fails, resulting in a possible stack overflow.
75 The implementation now falls back to an uncached collation sequence lookup
78 * CVE-2013-4788 The pointer guard used for pointer mangling was not
79 initialized for static applications resulting in the security feature
80 being disabled. The pointer guard is now correctly initialized to a
81 random value for static applications. Existing static applications need
82 to be recompiled to take advantage of the fix (bug 15754).
84 * CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes
85 to the d_name member of struct dirent, or omit the terminating NUL
86 character. (Bugzilla #14699).
88 * CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and
89 aligned_alloc functions could allocate too few bytes or corrupt the
90 heap when passed very large allocation size values (Bugzilla #15855,
93 * CVE-2013-4458 Stack overflow in getaddrinfo with large number of results
94 for AF_INET6 has been fixed (Bugzilla #16072).
96 * New locales: ak_GH, anp_IN, ar_SS, cmn_TW, hak_TW, lzh_TW, nan_TW, pap_AW,
97 pap_CW, quz_PE, the_NP.
99 * Substantially revised locales: gd_GB, ht_HT
101 * The LC_ADDRESS field was updated to support country_car for almost all
104 * ISO 1427 definitions were updated.
106 * ISO 3166 definitions were updated.
108 * The localedef utility now supports --big-endian and --little-endian
109 command-line options to generate locales for a different system from that
110 for which the C library was built.
112 * Binary locale files now only depend on the endianness of the system for
113 which they are generated and not on other properties of that system. As a
114 consequence, binary files generated with new localedef may be incompatible
115 with old versions of the GNU C Library, and binary files generated with
116 old localedef may be incompatible with this version of the GNU C Library,
117 in the following circumstances:
119 + Locale files may be incompatible on m68k systems.
121 + Locale archive files (but not separate files for individual locales) may
122 be incompatible on systems where plain "char" is signed.
124 * The configure option --disable-versioning has been removed. Builds with
125 --disable-versioning had not worked for several years.
127 * ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh,
128 cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue).
130 * SystemTap probes for malloc have been introduced.
132 * SystemTap probes for slow multiple precision fallback paths of
133 transcendental functions have been introduced.
135 * Support for powerpc64le has been added.
137 * The soft-float powerpc port now supports e500 processors.
139 * Support for STT_GNU_IFUNC symbols added for ppc32/power4+ and ppc64.
141 * A new feature test macro _DEFAULT_SOURCE is available to enable the same
142 set of header declarations that are enabled by default, even when other
143 feature test macros or compiler options such as -std=c99 would otherwise
144 disable some of those declarations.
146 * The _BSD_SOURCE feature test macro no longer enables BSD interfaces that
147 conflict with POSIX. The libbsd-compat library (which was a dummy library
148 that did nothing) has also been removed.
150 * Preliminary documentation about Multi-Thread, Async-Signal and
151 Async-Cancel Safety has been added.
155 * The following bugs are resolved with this release:
157 2546, 2560, 5159, 6809, 7006, 10060, 10062, 10283, 10357, 10686, 11120,
158 11561, 12310, 12387, 12492, 12515, 12723, 13550, 13889, 13951, 13988,
159 14142, 14176, 14200, 14256, 14280, 14293, 14317, 14327, 14478, 14496,
160 14582, 14686, 14812, 14888, 14894, 14907, 14908, 14909, 14920, 14952,
161 14964, 14981, 14982, 14985, 14991, 14994, 14996, 15000, 15003, 15006,
162 15007, 15014, 15020, 15022, 15023, 15036, 15054, 15055, 15062, 15078,
163 15084, 15085, 15086, 15100, 15160, 15214, 15221, 15232, 15234, 15283,
164 15285, 15287, 15304, 15305, 15307, 15309, 15327, 15330, 15335, 15336,
165 15337, 15339, 15342, 15346, 15359, 15361, 15366, 15380, 15381, 15394,
166 15395, 15405, 15406, 15409, 15416, 15418, 15419, 15423, 15424, 15426,
167 15429, 15431, 15432, 15441, 15442, 15448, 15465, 15480, 15485, 15488,
168 15490, 15492, 15493, 15497, 15506, 15529, 15536, 15553, 15577, 15583,
169 15618, 15627, 15631, 15654, 15655, 15666, 15667, 15674, 15711, 15755,
172 * CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
173 has been fixed by disabling the use of pt_chown (Bugzilla #15755).
174 Distributions can re-enable building and using pt_chown via the new configure
175 option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
176 considerable security risks and should only be used if the distribution
177 understands and accepts the risks.
179 * CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
182 * CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
183 fixed (Bugzilla #15330).
185 * Add support for calling C++11 thread_local object destructors on thread
186 and program exit. This needs compiler support for offloading C++11
187 destructor calls to glibc.
189 * Improved worst case performance of libm functions with double inputs and
192 * Support for priority inherited mutexes in pthread condition variables on
193 non-x86 architectures.
195 * Port to Xilinx MicroBlaze contributed by David Holsgrove.
197 * Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
199 * Optimized string functions for ARM. Implemented by Will Newton and
202 * Optimized libm functions for SPARC. Implemented by David S. Miller.
204 * Support for building more of ARM glibc as Thumb-2 code. Implemented by
207 * Support for building most of MIPS glibc as MIPS16 code. Implemented by
208 Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
210 * Added a benchmark framework to track performance of functions in glibc.
212 * New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
213 It is based on draft TS 18661 and currently enabled as a GNU extension.
215 * On Linux, the clock function now uses the clock_gettime system call
216 for improved precision, rather than old times system call.
218 * Added support for version-3 tz format files. This is needed when using
219 the tz database release 2013e or later, and affects a few unusual cases --
220 currently only TZ='America/Godthab' for time stamps after 2037.
222 * Added new API functions pthread_getattr_default_np and
223 pthread_setattr_default_np to get and set the default pthread
224 attributes of a process.
226 * Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
227 This may improve lock scaling of existing programs on TSX capable systems.
228 When the --enable-lock-elision=yes parameter is specified at configure
229 time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
232 * Support added for AT_HWCAP2 (to coincide with Linux kernel 3.10
233 availability). Implemented by Ryan S. Arnold.
235 * Support added for POWER8 platform. Implemented by Ryan S. Arnold.
239 * The following bugs are resolved with this release:
241 1349, 3439, 3479, 3665, 5044, 5246, 5298, 5400, 6530, 6677, 6778, 6808,
242 9685, 9914, 10014, 10038, 10114, 10191, 10631, 10873, 11438, 11607, 11638,
243 11741, 12140, 13013, 13412, 13542, 13601, 13603, 13604, 13629, 13679,
244 13696, 13698, 13717, 13741, 13759, 13761, 13763, 13881, 13939, 13950,
245 13952, 13966, 14042, 14047, 14090, 14150, 14151, 14152, 14154, 14157,
246 14166, 14173, 14195, 14197, 14237, 14246, 14251, 14252, 14283, 14298,
247 14303, 14307, 14328, 14331, 14336, 14337, 14347, 14349, 14368, 14376,
248 14417, 14447, 14459, 14476, 14477, 14501, 14505, 14510, 14516, 14518,
249 14519, 14530, 14532, 14538, 14543, 14544, 14545, 14557, 14562, 14568,
250 14576, 14579, 14583, 14587, 14595, 14602, 14610, 14621, 14638, 14645,
251 14648, 14652, 14660, 14661, 14669, 14672, 14683, 14694, 14716, 14719,
252 14743, 14767, 14783, 14784, 14785, 14793, 14796, 14797, 14801, 14803,
253 14805, 14807, 14811, 14815, 14821, 14822, 14824, 14828, 14831, 14833,
254 14835, 14838, 14856, 14863, 14865, 14866, 14868, 14869, 14871, 14872,
255 14879, 14889, 14893, 14898, 14914.
257 * Optimization of memcpy for MIPS.
259 * CVE-2011-4609 svc_run() produces high cpu usage when accept fails with
260 EMFILE has been fixed (Bugzilla #14889).
262 * The add-on ports collection is now distributed in the "ports" subdirectory
263 of the main GNU C Library distribution, rather than separately.
265 * Port to ARM AArch64 contributed by Linaro.
267 * Support for STT_GNU_IFUNC symbols added for s390 and s390x.
268 Optimized versions of memcpy, memset, and memcmp added for System z10 and
270 Implemented by Andreas Krebbel.
272 * The new function secure_getenv allows secure access to the environment,
273 returning NULL if running in a SUID/SGID process. This function replaces
274 the internal function __secure_getenv.
276 * SystemTap static probes have been added into the dynamic linker.
277 Implemented by Gary Benson.
279 * Optimizations of string functions strstr, strcasestr and memmem.
280 Implemented by Maxim Kuvyrkov.
282 * The minimum Linux kernel version that this version of the GNU C Library
283 can be used with is 2.6.16.
285 * Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
286 powerpc POWER7. Implemented by Will Schmidt.
288 * New configure option --disable-nscd builds the C library such that it
289 never attempts to contact the Name Service Caching Daemon (nscd).
290 New configure option --disable-build-nscd avoids building nscd itself;
291 this is the default if --disable-nscd is used.
293 * Improved support for cross-compilation, including cross-testing and
294 bootstrap builds without a previously built glibc.
296 * Several testsuite tests are now able to test multiple IFUNC variants of an
297 interface, rather than just testing the one that would be chooen by
300 * New configure options --with-bugurl and --with-pkgversion, for
301 distributors to use to embed their bug-reporting and package version
302 information in --help and --version output.
304 * The ttyname and ttyname_r functions on Linux now fall back to searching for
305 the tty file descriptor in /dev/pts or /dev if /proc is not available. This
306 allows creation of chroots without the procfs mounted on /proc.
308 * The `crypt' function now fails if passed salt bytes that violate the
309 specification for those values. On Linux, the `crypt' function will
310 consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
311 enabled, and fail on encrypted strings using the MD5 or DES algorithm
312 when the mode is enabled.
314 * The `clock_*' suite of functions (declared in <time.h>) is now available
315 directly in the main C library. Previously it was necessary to link with
316 -lrt to use these functions. This change has the effect that a
317 single-threaded program that uses a function such as `clock_gettime' (and
318 is not linked with -lrt) will no longer implicitly load the pthreads
319 library at runtime and so will not suffer the overheads associated with
320 multi-thread support in other code such as the C++ runtime library.
322 * New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ,
327 * The following bugs are resolved with this release:
329 174, 208, 350, 369, 411, 706, 766, 887, 2074, 2541, 2547, 2548, 2550,
330 2551, 2552, 2553, 2554, 2562, 2563, 2565, 2566, 2570, 2576, 2636, 2678,

353 * Support for the x32 ABI on x86-64 added. The x32 target is selected by
354 configuring glibc with:
355 BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'
356 Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info.
357 Implemented by H.J. Lu.
361 + define static_assert
363 + do not declare gets
365 + declare at_quick_exit and quick_exit also for ISO C11
367 + aligned_alloc. NB: The code is deliberately allows the size parameter
368 to not be a multiple of the alignment. This is a moronic requirement
369 in the standard but it is only a requirement on the caller, not the
374 + uchar.h support added
376 + CMPLX, CMPLXF, CMPLXL added
378 Implemented by Ulrich Drepper.
380 * Support for the IA-64 has been moved to ports.
382 * Remove support for anything but ELF binary format
384 * Checking versions of poll, ppoll added.
385 Implemented by Ulrich Drepper.
387 * More generic and 64-bit performance optimizations to math functions.
388 Implemented by Ulrich Drepper.
390 * New configure option --enable-obsolete-rpc makes the deprecated RPC
391 headers and functions available at compile time as they were before
392 version 2.14. This option will be removed at some time in the future
393 after the TI-RPC library becomes fully sufficient for the needs of
394 existing applications.
396 * Compatibility code for Linux kernel versions before 2.4 has been removed.
397 Note that glibc is not expected to work with any Linux kernel version
400 * New header <sys/auxv.h> and function getauxval allowing easy access to
401 the AT_* key-value pairs passed from the Linux kernel. The header also
402 defines the HWCAP_* bits associated with the AT_HWCAP key.
404 * New locales: mag_IN
406 * New configure option --enable-systemtap builds SystemTap static probes
407 into libc for setjmp and longjmp and into libpthread for various operations.
408 So far the setjmp/longjmp probes and some of the libpthread probes are
409 provided only for i*86 and x86_64.
410 Implemented by Roland McGrath and Rayson Ho.
412 * Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva.
414 * More optimized functions for PowerPC. Implemented by Adhemerval Zanella
417 * More optimized functions for SPARC. Implemented by David S. Miller.
419 * Improved support for cross-compilation, especially bootstrap builds
420 without a previously built glibc.
422 * Ports for the TILE-Gx and TILEPro families of processors. Contributed by
423 Chris Metcalf from Tilera.
425 * Support for the old ARM ABI has been removed from ports. Only the EABI is
426 now supported for ARM processors.
428 * The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
429 as the name of the dynamic linker, to distinguish it from the
430 /lib/ld-linux.so.3 dynamic linker used for the base EABI.
432 * Support for CRIS has been removed from ports.
434 * A new class of installed header has been documented for low-level
435 platform-specific functionality. PowerPC added the first instance with a
436 function to provide time base register access. Contributed by Tulio
437 Magno Quites Machado Filho.
439 * ix86 configurations now install header files that are consistent with
440 what x86-64 configurations install. These same header files can be used
441 for -m32, -m64, or -mx32 builds.
442 Contributed by H.J. Lu.
444 * Math library bug fixes. A thorough audit of all open math library bugs was
445 conducted by Joseph Myers. Significant progress was made on many math
446 library bugs resulting in more accurate exceptions and function results.
447 Many thanks to all those that contributed including Andreas Jaeger for his
448 patch review and work on the x87 trigonometric instruction issues.
450 * Timezone data is no longer installed. Timezone-related binaries and scripts
451 will continue to be installed. Users should obtain their timezone data from
452 their distribution provider or from the tzdata package at
453 <ftp://munnari.oz.au/pub/>.
457 * The following bugs are resolved with this release:

467 * New program pldd to list loaded object of a process
468 Implemented by Ulrich Drepper.
470 * Add nss_db support back to glibc. No more dependency on Berkeley db
471 and support for initgroups lookups.
472 Implemented by Ulrich Drepper.
474 * Optimized strcpy, strncpy, stpcpy, stpncpy for SSE2 and SSSE3 on x86-32.
475 Contributed by HJ Lu.
477 * Improved strcpy, strncpy, stpcpy, stpncpy for SSE2 and SSSE3 on x86-64.

492 Implemented by Ulrich Drepper.
494 * Checking versions of FD_SET, FD_CLR, and FD_ISSET added.
495 Implemented by Ulrich Drepper.
497 * nscd now also caches the netgroup database.
498 Implemented by Ulrich Drepper.
500 * Integrate libm with gcc's -ffinite-math-only option.
501 Implemented by Ulrich Drepper.
503 * Lots of generic, 64-bit, and x86-64-specific performance optimizations
504 to math functions. Implemented by Ulrich Drepper.
506 * Optimized strcasecmp and strncasecmp for AVX on x86-64.
507 Implemented by Ulrich Drepper.
509 * New Linux interfaces: process_vm_readv, process_vm_writev

532 12795, 12811, 12813, 12814, 12841
534 * The RPC implementation in libc is obsoleted. Old programs keep working
535 but new programs cannot be linked with the routines in libc anymore.
536 Programs in need of RPC functionality must be linked against TI-RPC.
537 The TI-RPC implementation is IPv6 enabled and there are other benefits.
539 Visible changes of this change include (obviously) the inability to link
540 programs using RPC functions without referencing the TI-RPC library and the
541 removal of the RPC headers from the glibc headers.
542 Implemented by Ulrich Drepper.
544 * New Linux interfaces: clock_adjtime, name_to_handle_at, open_by_handle_at,
545 syncfs, setns, sendmmsg
547 * New locales: os_RU, bem_ZA, en_ZA, ff_SN, sw_KE, sw_TZ, lb_LU, wae_CH,
548 yue_HK, lij_IT, mhr_RU
550 * New encodings: CP770, CP771, CP772, CP773, CP774
552 * New program sotruss to trace calls through PLTs
553 Implemented by Ulrich Drepper.
555 * The malloc hook implementation is marked deprecated and will be removed
556 from the default implementation in the next version. The design never
557 worked ever since the introduction of threads. Even programs which do
558 not create threads themselves can use multiple threads created internally.
562 * The following bugs are resolved with this release:
564 3268, 6812, 7066, 10085, 10484, 10563, 10851, 11149, 11155, 11577, 11611,

570 * New Linux interfaces: prlimit, prlimit64, fanotify_init, fanotify_mark
572 * POWER7 optimizations: memset, memcmp, strncmp
574 * New optimized string functions for x86-64: strnlen (SSE2),
575 strcasecmp (SSE2, SSSE3, SSE4.2), strncasecmp (SSE2, SSSE3, SSE4.2)
576 Implemented by Ulrich Drepper.

591 * New interfaces: pthread_getname_np, pthread_setname_np
593 * New Linux interface: recvmmsg
595 * STT_GNU_IFUNC implemented for Sparc by David Miller.
597 * The dynamic linker now recognizes supported ABI versions from the
598 EI_ABIVERSION field in the ELF header.
599 Implemented by Ulrich Drepper.
601 * New NIS mode selector ADJUNCT_AS_SHADOW. The passwd.adjunct.byname table
602 will not be used to fill in password fields in the passwd.byname replies.
603 Instead it is used to synthesize the shadow.byname table, should it be
604 missing. This is a useful mode in some installations involving Solaris.
605 Implemented by Ulrich Drepper.
607 * New locales: kok_IN, sq_MK, cv_RU
611 * The following bugs are resolved with this release:
613 3270, 7094, 9924, 9986, 10011, 10085, 10107, 10159, 10162, 10166, 10183,

618 10789, 10817, 10823, 10840, 10847
620 * New interfaces: execvpe, pthread_sigqueue, mkstemps, mkstemps64, mkostemps,
622 Implemented by Ulrich Drepper.
624 * Checking version of longjmp added that fails if an uninitialized stack
625 frame would be created. Implemented by Ulrich Drepper.
627 * STT_GNU_IFUNC is now supported in static executables.
628 Implemented by H.J. Lu.
630 * STT_GNU_IFUNC implemented for PPC by Alan Modra.
632 * New optimized string functions for x86-64: strstr, strcasestr, memcmp,
633 strcspn, strpbrk, strspn, strcpy, stpcpy, strncpy, strcmp (SSE2, SSE4.2),
634 strncmp (SSE2, SSE4.2), strchr (SSE4.2), strrchr (SSE4.2).
635 Contributed by H.J. Lu.
637 strlen, rawmemchr, strcmp (SSSE3), strncmp (SSSE3).
638 Implemented by Ulrich Drepper.
640 * New optimized string functions for x86: strlen, strcspn, strspn, strpbrk,
642 Contributed by H.J. Lu.
644 * Support for fma instruction in AVX on x86-64.
645 Implemented by H.J. Lu and Ulrich Drepper.
647 * AVX support in x86-64 auditing support in ld.so.
648 Implemented by H.J. Lu.
650 * STB_GNU_UNIQUE support added.
651 Implemented by Ulrich Drepper.
653 * Implement second fallback mode for optimized DNS lookup for even more
654 broken environments. If two requests from the same port are not
655 handled correctly close the socket and open a new one before sending
656 the second request. The 'single-request-reopen' option in /etc/resolv.conf
657 can be used to select this mode right away, instead of rediscovering the
658 necessity is every process again.
659 Implemented by Ulrich Drepper.
661 * New resolver flag RES_USE_DNSSEC to enable use of verified lookup.
662 Implemented by Adam Tkac.
664 * Optimized iconv conversions for S390x.
665 Implemented by Andreas Krebbel.
667 * Using condvars with PI mutexes is now more efficient due to kernel
668 support for requeueing to PI futexes. NPTL support added for x86-64.
669 Implemented by Ulrich Drepper.
671 * New locales: ps_AF, my_MM
675 * The following bugs are resolved with this release:
677 697, 5381, 5807, 6411, 6545, 7040, 7058, 7067, 7080, 7083, 7095, 7098,
678 9677, 9694, 9697, 9701, 9704, 9705, 9706, 9720, 9726, 9730, 9733, 9736,

683 * New interfaces: preadv, preadv64, pwritev, pwritev64, malloc_info
684 Implemented by Ulrich Drepper.
686 * New Linux interfaces: accept4, fallocate, fallocate64.
687 Implemented by Ulrich Drepper.
689 * Correct declarations of string function when used in C++ code. This
690 could lead to compile errors for invalid C++ code.
692 * XPG7/POSIX 2008 compilation environment. Many GNU-specific functions are
695 * New POSIX 2008 interface: psiginfo
696 Implemented by Ulrich Drepper.
698 * New ISO C++1x interfaces: quick_exit, at_quick_exit
699 Implemented by Ulrich Drepper.
701 * Support for selecting between multiple function definitions at runtime
702 using STT_GNU_IFUNC symbols. Implemented by Ulrich Drepper.
704 * The libcrypt library can now use the hash function implementations in
705 NSS. Implemented by Ulrich Drepper.
707 * The malloc implementation can be compiled to be less memory efficient
708 but higher performing in multi-threaded programs.
709 Implemented by Ulrich Drepper.
711 * New locales: nan_TW@latin, ks_IN
713 * Faster strlen, strchr, strchrnul, strrchr, memchr, and rawmemchr for x86-64.
714 Implemented by Ulrich Drepper.
716 * Extended printf hook support. It is possible to use user-defined types
717 and extend existing format specifiers.
718 Implemented by Ulrich Drepper.
720 * Handling for group shadow files has been added.
721 Implemented by Ulrich Drepper.
723 * DNS IPv4-IPv6 parallel lookup now deals better with broken DNS
724 servers (the case, e.g., for some people using the built-in DNS
725 server in ADSL modems/routers). There is a once-per-process timeout
726 in case of a broken server. To avoid it, users can run nscd or put
727 'options single-request' in /etc/resolv.conf.
728 Implemented by Ulrich Drepper.

741 up at the same time. Implemented by Ulrich Drepper.
743 * TLS descriptors for LD and GD on x86 and x86-64.
744 Implemented by Alexandre Oliva.
746 * getaddrinfo now handles DCCP and UDPlite.

763 use the buffer end, not the string length as the basis.
764 Implemented by Ulrich Drepper.
766 * Many functions, exported and internal, now atomically set the close-on-exec
767 flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper.

803 vdprintf, and obstack_vprintf.
804 Implemented by Jakub Jelinek.
806 * Faster memset for x86-64.
807 Implemented by Harsha Jagasia and H.J. Lu.
809 * Faster memcpy on x86.
810 Implemented by Ulrich Drepper.
812 * ARG_MAX is not anymore constant on Linux. Use sysconf(_SC_ARG_MAX).
813 Implemented by Ulrich Drepper.
815 * Faster sqrt and sqrtf implemention for some PPC variants.
816 Implemented by Steven Munroe.
820 * The following bugs are resolved with this release:
822 4125, 4126, 4178, 4359, 4407, 4512, 4514, 4525, 4554, 4556, 4557, 4566,

826 5071, 5103, 5104, 5112, 5113, 5184, 5186
828 * More checking functions: fread, fread_unlocked, open*, mq_open.
829 Implemented by Jakub Jelinek and Ulrich Drepper.
831 * Extend fortification to C++. Implemented by Jakub Jelinek.
833 * Implement 'm' modifier for scanf. Add stricter C99/SUS compliance
834 by not recognizing 'a' as a modifier when those specs are requested.
835 Implemented by Jakub Jelinek.
837 * PPC optimizations to math and string functions.
838 Implemented by Steven Munroe.
840 * New interfaces: mkostemp, mkostemp64. Like mkstemp* but allow additional

879 * New Linux interfaces: epoll_pwait, sched_getcpu.
881 * New generic interfaces: strerror_l.
883 * nscd can now cache the services database. Implemented by Ulrich Drepper.
887 * The following bugs are resolved with this release:
889 39, 68, 192, 352, 388, 531, 935, 1006, 1201, 1203, 1386, 1782, 1783, 1784,

897 3225, 3251, 3252, 3253, 3273
899 * For Linux, the sorting of addresses returned by getaddrinfo now also
900 handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled.
901 Implemented by Ulrich Drepper.
903 * Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
904 Implemented by Ulrich Drepper.
906 * New Linux interfaces: splice, tee, sync_file_range, vmsplice.
908 * New iconv module for MIK. Contributed by Alexander Shopov.
910 * For sites with broken group and/or passwd database, the auto-propagate
911 option of nscd can prevent creating ID lookup entries from the results
912 of a name lookup and vice versa. This usually is no problem but some
913 site might have problems with the default behavior.
914 Implemented by Ulrich Drepper.
916 * Iterating over entire database in NIS can be slow. With the
917 SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
918 to trade time for memory. The entire database will be read at once.
919 Implemented by Ulrich Drepper.
921 * The interfaces introduced in RFC 3542 have been implemented by
924 * Support for the new ELF hash table format was added by Ulrich Drepper.
926 * Support for priority inheritance mutexes added by Jakub Jelinek and
929 * Support for priority protected mutexes added by Jakub Jelinek.
931 * New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN,
932 or_IN, csb_PL, fy_NL, sr_ME.
936 * More overflow detection functions.
938 * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
939 IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.
941 More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097,

944 IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712,
945 IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
946 by Masahide Washizawa.
948 * It is now possible to install audit libraries for the dynamic linker using
949 LD_AUDIT. Implemented by Ulrich Drepper.
951 * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
952 longer supported. The new NPTL implementation requires Linux 2.6 kernels.
953 For a libc and libpthread that works well on Linux 2.4 kernels, we
954 recommend using the stable 2.3 branch.
956 * The new function open_wmemstream acts like open_memstream,
957 but uses a wchar_t wide character buffer.
959 * The new function ppoll is an improved version of poll, similar to pselect.
961 * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
962 futimesat, faccessat, mkdirat, mkfifoat, mknodat,
963 renameat, unlinkat, linkat, symlinkat, readlinkat.
965 * New Linux kernel system calls: unshare,
966 inotify_init, inotify_add_watch, inotify_rm_watch.
968 * The euidaccess function is now also known by the alias eaccess,
969 for compatibility with some other systems.
971 * Timezone data updated to 2006b version.
975 * The following bugs are resolved with this release:
977 38, 253, 549, 622, 653, 721, 758, 851, 877, 915, 934, 955, 961,

984 Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
986 * As of this release, GCC 4 can be used to compile the C Library.
988 * Timezone data updated to 2005m version.
992 * The following bugs are resolved with this release:
994 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719,

999 Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
1003 * Support for RFC 3678. Real implementations exist only for Linux so far.
1004 Implemented by Ulrich Drepper.
1006 * nscd can now cache entries persistently. Expiring entries are reloaded.
1007 For speedups the cache can be shared in memory with client processes.
1008 Implemented by Ulrich Drepper.
1010 * nscd can now perform SELinux checks.
1011 Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
1013 * getaddrinfo queries are now cached. Canonical name lookup is performed
1015 Implemented by Ulrich Drepper.
1017 * The nothrow function attribute is used when headers are used by gcc when
1018 compiling C code. This can avoid significant amounts of exception
1021 * The malloc functions perform more error checking and are stricter when
1022 it comes to reacting on errors. The default action is to terminate
1023 the process after showing an error message. Implemented by Ulrich Drepper.
1025 * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
1026 lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
1028 * Namespaces in ld.so are implemented. DSOs can be loaded in separate
1029 namespaces using the new function dlmopen(). This feature is of course,
1030 like most other dynamic loading functionality, not available in statically
1031 linked applications. Implemented by Ulrich Drepper.
1033 * Low-overhead boundary checking variants of string and some stdio functions
1034 were added. These are to be used in conjunction with a gcc patch by
1035 Jakub Jelinek which adds calls to these functions if possible.
1036 Implemented by Jakub Jelinek and Ulrich Drepper.
1038 * Old code for several operating systems and machine architectures that
1039 have not been in working condition in a long time have been removed from
1040 the main source tree maintained by the GNU C Library's maintainers.
1041 These files are now reside in the separate `ports' source module
1042 that is usable as an add-on when building the library.
1046 * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to
1047 interrogate the dynamic linker, compatible with the Solaris interface.
1049 * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64;
1050 implemented by Paul Mackerras, Steven Munroe, and Roland McGrath.
1052 * getifaddrs now uses the netlink interface on Linux to get its information.
1053 Implemented by Thorsten Kukuk.
1055 * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF.
1056 Implemented by Ulrich Drepper.
1058 * support for non-executable stacks on x86 has been added. Changes mostly
1061 * regex is now much faster for multibyte locales. Changes by Jakub Jelinek
1064 * getaddrinfo now performs destination address selection according to
1069 * Thread-safe interfaces for many functions that access locale data
1070 were added in version 2.3, but these features were omitted from NEWS.
1071 Many functions have variants with an `_l' suffix that take a `locale_t'
1072 object as a parameter rather than consulting the current locale.
1073 The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
1074 create and maintain `locale_t' objects. Additionally, the new function
1075 `uselocale' sets "the current locale" (as used by functions not so
1076 parameterized) set for an individual thread. These features were added
1077 in version 2.3, implemented by Ulrich Drepper and Roland McGrath.
1079 * The functions getresuid, getresgid, setresuid, and setresgid, which
1080 have long been available on Linux, are now declared in <unistd.h>
1081 and are now also available on the Hurd.
1083 * ELF thread-local storage support (TLS) now works on x86-64.
1085 * The new dynamic string token $LIB is expanded in shared library names.
1086 This normally expands to lib, but on some 64-bit platforms to lib64 instead.
1088 * Aldy Hernandez contributed complete software floating point support for
1089 PowerPC machines with no FPU.
1091 * fexecve is implemented on Linux.
1093 * The `btowc' function should work at least twice as fast due to
1094 specialized callbacks in the iconv modules. Implemented by Bruno Haible.
1096 * With approriate thread add-ons cancelable functions are now implemented
1097 in libc.so as well. No need to call the function in libpthread. This
1098 change allowed to finally disable the incorrect and expensive handling
1099 of weak definition in ld.so.
1101 * Yet more PLT entries in libc.so have been removed. We finally arrived
1102 at the bare minimum. Startup times improved appropriately.
1104 * Support for the new Linux/x86 system call interface was added. The
1105 AT_SYSINFO auxiliary vector entry is recognized and handled.
1109 * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164
1112 * iconv (the program and the interface) now accepts empty names (excluding
1113 options like //TRANSLIT) to mean "use charset of current locale".
1115 * localedef can now transliterate characters in strings which are not in
1116 the provided charmap. The information from the input locale is used.
1118 * Prelinking support was added for ELF targets. This requires additional
1119 tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek.
1121 * Read-only stdio streams now use mmap to speed up operation by eliminating
1122 copying and buffer underflows. To use add 'm' to the mode string of
1123 the fopen/fdopen/freopen call. Implemented by Ulrich Drepper.
1125 * The malloc functions were completely rewritten by Wolfram Gloger based
1126 on Doug Lea's malloc-2.7.0.c.
1128 * Isamu Hasegawa contributed a completely new and POSIX-conformant
1129 implementation of regex.
1131 * Bruno Haible upgraded the iconv and locale implementation to support
1134 * Contents of the LC_* and LANG environment variables in the CEN style are
1135 not recognized anymore. It never was used. Change by Ulrich Drepper.
1137 * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF
1138 thread-local storage (TLS) ABI on some platforms.
1139 Changes by Ulrich Drepper. SH support by Kaz Kojima.
1141 * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213,
1142 EUC-JISX0213, and TSCII.
1144 * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs':
1145 BSD-compatible interface for getting all network interface addresses.
1146 Implementation for IPv4 by Roland McGrath.
1148 * Loading of locale data is faster due to the introduction of a locale
1149 archive. Implemented by Roland McGrath and Ulrich Drepper.
1151 * Startup times are significantly reduced by not using exported functions
1152 inside the library itself. Changes by Jakub Jelinek, Roland McGrath,
1155 * Steven Munroe contributed a port to PowerPC64/Linux.
1159 * The Hurd now uses the GNU libio implementation of stdio rather than the
1160 old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
1162 * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
1163 with the same behavior as the Linux system call of the same name.
1167 * Stephen Moshier implemented log2, log10, powl and cbrtl for the
1168 128-bit long double format.
1170 * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160,
1171 IBM1161, and IBM1162 charsets.
1173 * Andreas Jaeger contributed a port to x86-64/Linux.
1175 * Peter Bruin contributed a port to PowerPC/Hurd.
1177 * libc functions using I/O streams now can handle wide-oriented streams
1180 * optimizations in the dynamic linker. Binaries created by recent binutils
1181 versions start up quicker due to reduced time spent on relocations.
1183 * Support for use of gcc3 added by Jakub Jelinek and HJ Lu.
1187 * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
1188 asinh, atanh, j0 for the 128-bit long double format.
1190 * Bruno Haible updated all the code handling Unicode in some form to
1191 support Unicode 3.1.
1193 * Speed of regex for single-byte locales is back to previous levels.
1194 Patch by Isamu Hasegawa.
1196 * Alpha, SPARC, and IA-64 now also using floating stacks.
1198 * Startup time of internationalized applications greatly improved through
1199 iconv cache. Use iconvconfig to generate the cache file.
1200 Contributed by Ulrich Drepper.
1202 * The IA-64 specific part of ld.so was rewritten to eliminate some pretty
1203 severe performance problems. Patch by David Mosberger.
1205 * The Hurd port got a lot more functionality like AIO, various stdio
1206 extensions, etc. Mainly done by Roland McGrath.
1208 * mtrace can now lookup symbols in shared libraries.
1212 * Intel's IA-64 math library is largely integrated. It provides fast and
1213 accurate implementatations for most basic and standard math functions
1214 in float, double, and long double format.
1216 * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
1217 and asin for the 96-bit long double format and asin, log, tan for the
1218 128-bit long double format.
1220 * The beginning of a last-bit accurate math library by IBM Haifa were added.
1221 The basic double functions exist today. Contributed by Abraham Ziv
1222 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
1223 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
1225 * An asynchronous name lookup library was added. The interface is designed
1226 after POSIX AIO. The proposal was circulated beforehand to get comments.
1227 No negative ones came in. Implemented by Ulrich Drepper.
1229 * Port to S390/64bit contributed by Martin Schwidefsky
1230 <schwidefsky@de.ibm.com>.
1232 * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
1233 of functions for Linux/IA-64.
1235 * The RPC code is now thread safe. Threads can now use the same service
1236 of different services at the same time. Patch by Eric Norum
1237 <eric.norum@usask.ca> with some help by Ulrich Drepper.
1239 * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
1240 family of functions for Linux/S390.
1242 * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
1243 of functions for Linux/x86.
1245 * Port to Linux/CRIS contributed by Axis Communications.
1249 * Lots of headers were cleaned up. Using the tool in the conform/ subdir
1250 we can now check for namespace violations and missing declarations. The
1251 result is that almost all headers are now Unix-compliant (as defined in
1252 the upcoming XPG6). The negative side is that some programs might need
1253 corrections, too, if they depend on the incorrect form of the headers in
1254 previous versions which defined too many symbols and included too many
1257 * regex now handles multibyte character sets correctly.
1258 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
1260 * iconv (the program) does now conform to the upcoming XPG6 and handles
1261 charmaps. Instead of the charset names the path of charmaps can be
1262 provided and the conversion happens based on this data.
1263 Contributed by Ulrich Drepper.
1265 * The locale program now provides detailed information about the installed
1270 only lists the names of the supported locales
1274 provides details such as country, language, and codeset name.
1275 Contributed by Ulrich Drepper.
1279 * The gencat program now parses the input file according to the charset
1280 selected by the LC_CTYPE category. This is important for stateful
1281 character sets. To make generating catalogs easier there is a way
1282 to overwrite the charset selected by the locale: before the first
1283 message or $ quote line the catalog can contain a line like
1285 $ codeset=ISO-8859-2
1287 to select the charset (ISO-8859-2 in this case).
1289 Implemented by Shinya Hanataka and Ulrich Drepper.
1291 * New codeset conversion modules: IBM-922 (Estonia PC codeset),
1292 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
1293 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
1295 * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
1296 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
1298 * The LANGUAGE environment variable is now ignored unless the locale is
1299 changed from the default "C" locale.
1301 * The usual bug fixes.
1305 * Greg McGary added runtime support for bounds checking using gcc's
1306 new -fbounded-pointers option. ix86 target is complete. PowerPC
1309 * Thorsten Kukuk added secure mode support to nscd.
1311 * The Berkeley db libraries have been removed.
1313 Related, the nss_db module is now in a separate package since it
1314 obviously requires a database library being available.
1316 * Wide character I/O streams implemented by Ulrich Drepper.
1318 * Functions from the extended socket API added by Ulrich Drepper.
1320 * Functions feenableexcept and fedisableexcept to control the
1321 behaviour of individual exceptions have been added by Andreas Jaeger.
1323 * ldconfig program added by Andreas Jaeger and Jakub Jelinek.
1325 * The resolver code has been updated from bind 8.2.3-T5B which supports
1326 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
1329 This change could in some situations effect backward compatibility. Since
1330 now `_res' is a thread-local instead of a global variable, modifying it
1331 in one thread does not have any effect in other threads.
1333 The resolver library was also extended to allow IPv6 as the transport
1334 protocol for the requests. This work was done by Stig Venaas.
1336 * Compatibility code for K&R C compilers has been removed from the
1337 header files. A ISO C compiler is needed to use the library
1338 (conforming to either C89 or C99 standard).
1340 * Complete rewrite of the localedef program to support multibyte character
1341 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
1342 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
1343 Implemented by Ulrich Drepper.
1345 Bruno Haible significantly improved the generation and use of the data
1346 structures for the wide character tables.
1348 * Plural handling in gettext implemented by Ulrich Drepper.
1350 * The utmp daemon has been removed.
1352 * The port to MIPS-Linux has been finished by Andreas Jaeger.
1354 * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
1357 * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
1359 * POSIX barriers implemented by Kaz Kylheku.
1361 * POSIX spawn function family implemented by Ulrich Drepper.
1363 * POSIX spinlocks are now available.
1365 * Timed wait functions for mutex, rwlock, and semaphores are implemented.
1367 * the configure option --enable-kernel=X.Y.Z allows to strip out
1368 compatibility for kernel versions before X.Y.Z. This is currently only
1369 implemented for Linux.
1371 * the sockaddr_in6 structure changed. The IPv6 working group added a new
1372 field sin6_scope_id. This means that all programs using IPv6 should be
1373 recompiled. Don't expect binary compatibility with previous glibc
1376 * various conversion modules for IBM character sets contributed by
1379 * IA-64 port by Jes Sorensen and HJ Lu.
1393 * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
1395 * New xdr functions are added; some rpc functions are now 64bit clean.
1397 * Fixed a number of bugs and memory leaks (especially in NIS+ code).
1399 * Fixed known incompatibilities with glibc 2.0.
1401 * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
1403 * Optimized a number of functions (especially the ELF dynamic loader).
1405 * Update timezone data files.
1407 * lots of charmaps corrections
1409 * some new locale definitions and charmaps
1414 * Richard Henderson corrected size of struct timeval on Linux/Alpha to
1415 conform to POSIX member type requirements. Symbol versions have been
1416 adjusted as needed within the library, and for direct use by applications,
1417 but there is potential for problems if third-party libraries use
1418 struct timeval as part of their interface. This does not present
1419 a problem for X and other "essential" system libraries.
1421 * An additional locale model to support C++ Standard Library locale
1422 model and probably more was implemented by Ulrich Drepper.
1424 * Eric Youngdale and Ulrich Drepper implemented versioning of objects on
1427 * Miles Bader provided the `argp' function family to support hierachical
1428 command line argument parsing, layered on top of getopt.
1430 * strtod accepts new hexadecimal floating-point format from ISO C 9X.
1432 * printf has two new specifiers %a and %A to print hexadecimal flaoting-point
1435 * scanf recognizes the %a and %A format for scanning floating point numbers.
1437 * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
1438 information and interfaces for the available integer types.
1440 * about 130 new math functions were added to implement the ISO C9x math
1443 * the new header <complex.h> contains definitions of the complex math
1444 functions from ISO C 9X.
1446 * the new header <tgmath.h> defines generic macros to use complex or
1447 real valued functions.
1449 * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
1451 * Andreas Jaeger provided a test suite for the math library.
1453 * Mark Kettenis implemented the utmpx interface and an utmp daemon.
1455 * Ulrich Drepper added character set conversion functions (iconv).
1457 * Optimized string functions have been added.
1459 * The localedata addon is now part of glibc.
1461 * An implementation of profiling shared libraries was added by Ulrich Drepper.
1463 * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
1464 daemon for NSS (nscd).
1466 Missing a better place here are some numbers on improvements. Under
1467 Linux 2.1.125 un-tar-ing the kernel sources takes
1471 using local files 12.19s 6.88s 22.91s
1473 using NIS 13.92s 8.91s 26.34s
1475 using NIS & nscd 10.37s 7.34s 25.30s
1477 using NIS+ 27.57s 30.37s 640.46s
1479 using NIS+ & nscd 10.25s 7.83s 26.51s
1481 using NIS & old nscd [1] 13.83s 8.32s 29.60s
1483 Keep in mind that non-namelookup related operations dominate above times.
1484 It was just a common complain that using NIS+ unpacking the kernel is
1487 [1] The old nscd implementation is not available anymore since it was
1488 distributed with glibc up to version 2.0.98 and thus is now replaced.
1490 * Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
1492 * Mark Kettenis provided a Hesiod NSS module.
1494 * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
1495 and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
1497 * rcmd can now handle netgroups (Dick Streefland).
1499 * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
1502 * Support for the IPv6 protocol has been added to the socket API, as per the
1503 latest draft standards.
1505 * Support for Linux 2.2 has been added.
1507 * Interface changes relative to the latest 2.0.x release:

1839 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1850 * inet_ntoa is thread-safe
1852 * updwtmp is moved from libutil to libc
1854 * rewrite of cbrt function
1856 * update of timezone data
1870 * add atoll function
1872 * fix complex problems in Berkeley DB code
1874 * fix math functions
1878 * fixed lots of header problems (especially Linux/GNU specific)
1880 * dynamic loader preserves all registers
1882 * Roland McGrath provided support for handling of auxiliary objects in
1883 the ELF dynamic loader.
1885 * support for parallel builds is improved
1889 * GNU extensions are no longer declared by default. To enable them you
1890 must define the macro `_GNU_SOURCE' in your program or compile with
1893 * The library has changed from using GNU ld symbol aliases to using weak
1894 symbols where available. The ELF object file format supports weak
1895 symbols; GNU ld also supports weak symbols in the a.out format. (There
1896 is also now support for other GNU ld extensions in ELF. Use the
1897 `--with-elf' option to configure to indicate you have ELF, and
1898 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
1899 of many files which contained only symbol aliases, reducing the size of
1900 the source and the compiled library; many other files were renamed to
1901 less cryptic names previously occupied by the symbol alias files.
1902 There is a new header file <elf.h> for programs which operate on
1903 files in the ELF format.
1905 * Converted to Autoconf version 2, so `configure' has more options.
1906 Run `configure --help' to see the details.
1908 * The library can now be configured to build profiling, highly-optimized
1909 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
1910 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
1911 `configure' enable building these extra libraries. The shared library is
1912 built by default when using both ELF and GNU ld. When shared libraries
1913 are enabled, the new library `-ldl' is available for arbitrary run-time
1914 loading of shared objects; its interface is defined in <dlfcn.h>. The
1915 new header file <link.h> gives access to the internals of the run-time
1916 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
1917 application of same name on other systems and it provides information
1918 about dynamically linked binaries.
1920 * The C library now provides the run-time support code for profiling
1921 executables compiled with `-pg'. Programs can control the profiling code
1922 through the interface in <sys/gmon.h>. The `gmon.out' files written by
1923 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
1924 the support for this file format was contributed by David Mosberger-Tang.
1926 * The math code has been replaced with a math library based on fdlibm from
1927 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
1928 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
1929 functions. The math functions now reside in a separate library, so
1930 programs using them will need to use `-lm' their linking commands.
1932 * John C. Bowman contributed optimized ix87 assembler inline functions.
1934 * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
1935 mechanism similar to that found in Solaris 2. This is now used for the
1936 group, passwd, hosts, networks, services, protocols, rpc, ethers,
1937 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
1938 file controls what services are used for each individual database. This
1939 works by loading shared libraries with names specified in `nsswitch.conf',
1940 so service modules can be changed or added at any time without even
1941 relinking any program. Currently there are the file, db, and NIS based
1942 NSS services available.
1944 * The new functions `strtoq' and `strtouq' parse integer values from
1945 strings, like `strtol' and `strtoul', but they return `long long int' and
1946 `unsigned long long int' values, respectively (64-bit quantities).
1948 * The new functions `strtof' and `strtold' parse floating-point values from
1949 strings, like `strtod', but they return `float' and `long double' values,
1950 respectively (on some machines `double' and `long double' are the same).
1952 * Ulrich Drepper has contributed new implementations of the floating-point
1953 printing and reading code used in the `printf' family of functions and
1954 `strtod', `strtof', and `strtold'. These new functions are perfectly
1955 accurate, and much faster than the old ones.
1957 * The implementation of the POSIX locale model was completely rewritten by
1958 Ulrich Drepper. This includes the new programs `localedef' and `locale'
1959 to compile the POSIX locale definition.
1961 * The former dummy implementations of the strcoll and strxfrm function are
1962 now replaced by fully functional code contributed by Ulrich Drepper. The
1963 collation information comes from the POSIX locale definitions.
1965 * The new header <langinfo.h> defines an interface for accessing
1966 various locale-dependent data (using the locale chosen with `setlocale').
1968 * Ulrich Drepper has contributed a new suite of functions for operation on
1969 wide-character and multibyte-character strings, in <wchar.h>;
1970 and classification and case conversion of wide characters, in <wctype.h>.
1971 These new functions are conforming to the ISO C, Amendement 1 specification.
1973 * There is now a second implementation of the standard I/O library available.
1974 It comes from GNU libg++ as was written by Per Bothner, heavily modified
1975 by Hongjiu Lu and made thread safe by Ulrich Drepper.
1977 * You can now use positional parameter specifications in format strings
1978 for the `printf' and `scanf' families of functions. For example,
1979 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
1980 ``Number 6, Mr Jones''. This is mainly useful when providing different
1981 format strings for different languages, whose grammars may dictate
1982 different orderings of the values being printed. To support this
1983 feature, the interface for `register_printf_handler' has changed; see
1984 the header file <printf.h> for details.
1986 * The `printf' and `scanf' families of functions now understand a new
1987 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
1988 to group numbers as indicated by the locale; for `scanf' and friends, this
1989 says to accept as valid only a number with all the proper grouping
1990 separators in the right places. In the default "C" locale, numbers are
1991 not grouped; but locales for specific countries will define the usual
1992 conventions (i.e. separate thousands with `,' in the US locale).
1994 * The pgrp functions have been regularized, slightly incompatibly but much
1995 less confusingly. The core functions are now `getpgid' and `setpgid',
1996 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
1997 argument) and BSD `setpgrp' (identical to `setpgid') functions are
1998 provided for compatibility. There is no longer an incompatible `getpgrp'
1999 with an argument declared under _BSD_SOURCE; no BSD code uses it.
2001 * The new header file <fts.h> and suite of functions simplify programs that
2002 operate on directory trees. This code comes from 4.4 BSD.
2004 * The resolver code has been updated from the BIND 4.9.5-P1 release.
2005 Parts of the code were heavily modified by Ulrich Drepper to fit in the
2006 NSS scheme used in glibc.
2008 * There is a new malloc debugging hook `__memalign_hook'.
2010 * There are new typedefs `ushort' for `unsigned short int' and `uint' for
2011 `unsigned int' in <sys/types.h>. These are for compatibility only and
2012 their use is discouraged.
2014 * The `-lmcheck' library to enable standard malloc debugging hooks is now
2015 done differently, so that it works even without GNU ld.
2017 * New function `euidaccess' checks allowed access to a file like `access',
2018 but using the effective IDs instead of the real IDs.
2020 * The time zone data files have been updated for the latest and greatest
2021 local time conventions of the countries of the world.
2023 * The new function `dirfd' extracts the file descriptor used by a DIR stream;
2026 * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
2027 for formatting floating-point numbers. They are provided only for
2028 compatibility; new programs should use `sprintf' instead. There are
2029 also equivalent function for the `long double' floating-point type and
2030 all functions also exist in a reentrant form.
2032 * The new auxiliary library `-lutil' from 4.4 BSD contains various
2033 functions for maintaining the login-record files (primarily of use to
2034 system programs such as `login'), and convenient functions for
2035 allocating and initializing a pseudo-terminal (pty) device.
2037 * Ulrich Drepper has contributed new support for System V style
2038 shared memory and IPC on systems that support it.
2040 * Ulrich Drepper has contributed several miscellaneous new functions found
2041 in System V: The `hsearch' family of functions provide an effective
2042 implementation of hash tables; `a64l' and `l64a' provide a very simple
2043 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
2046 * Ulrich Drepper has contributed new reentrant counterparts for the
2047 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
2049 * Ulrich Drepper has contributed new, highly-optimized versions of several
2050 string functions for the i486/Pentium family of processors.
2052 * Ulrich Drepper has updated the Linux-specific code, based largely
2053 on work done in Hongjiu Lu's version of GNU libc for Linux.
2054 The GNU library now supports Linux versions 2.0.10 and later,
2055 using the ELF object file format (i[3456]86-*-linux).
2057 * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
2059 * David Mosberger-Tang and Richard Henderson have ported the C library
2060 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
2061 dynamic linking support for ELF/Alpha.
2063 * Richard Henderson contributed several Alpha optimized assembler function
2064 for arithmetic and string handling.
2066 * Ulrich Drepper has contributed a new set of message catalog functions to
2067 support multiple languages using the <libintl.h> interface, for use with
2068 his new package GNU gettext. Translation volunteers have contributed
2069 catalogs of the library's messages in Spanish, German, and Korean.
2071 * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
2072 program and the `catgets' function for reading the catalog files it
2073 creates. (The <libintl.h> interface is preferred; we include the
2074 <nl_types.h> interface using `catgets' only for source compatibility with
2075 programs already written to use it.)
2077 * New header file <values.h> gives SVID-compatible names for <limits.h>
2080 * Various new macros, declarations, and small header files for compatibility
2083 * New function `group_member' is a convenient way to check if a process has
2084 a given effective group ID.
2086 * When using GCC 2.7 and later, the socket functions are now declared in a
2087 special way so that passing an argument of type `struct sockaddr_in *',
2088 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
2089 `struct sockaddr *' type, does not generate a type-clash warning.
2091 * New function `error' declared in header file <error.h> is a convenient
2092 function for printing error messages and optionally exiting; this is the
2093 canonical function used in GNU programs. The new functions `err', `warn',
2094 and friends in header file <err.h> are the canonical 4.4 BSD interface for
2095 doing the same thing.
2097 * The <glob.h> interface has several new flags from 4.4 BSD that extend the
2098 POSIX.2 `glob' function to do ~ and {...} expansion.
2100 * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
2101 `clearenv' which is used in POSIX.9 is also available.
2103 * New function `getsid' returns session ID number on systems that support it.
2105 * We have incorporated the 4.4 BSD `db' library (version 1.85). New header
2106 files <db.h> and <mpool.h> provide a rich set of functions for several
2107 types of simple databases stored in memory and in files, and <ndbm.h> is
2108 an old `ndbm'-compatible interface using the `db' functions. Link with
2109 `-ldb' to get these functions.
2111 * New macro `strdupa' copies a string like `strdup', but uses local stack
2112 space from `alloca' instead of dynamic heap space from `malloc'.
2114 * New function `strnlen' is like `strlen' but searches only a given maximum
2115 number of characters for the null terminator. `stpncpy', `strndup' and
2116 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
2119 * New function `statfs' in header <sys/statfs.h>.
2121 * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
2122 provide convenient functions for operating on blocks of null-terminated
2125 * A new suite of functions in <utmp.h> handle all the details of reading
2126 and writing the utmp file.
2128 * An implementation of the NIS/YP(tm) based NSS service was contributed by
2131 * Paul Eggert and Ulrich Drepper modified the `strftime' function to be
2132 completely POSIX compliant and also implemented the extended functionality
2133 to handle alternate digit representation and alternate era date formats.
2135 * Ulrich Drepper provided an implementation of the `strptime' function
2136 defined in XPG4.2 which transforms a string into a `struct tm' value.
2138 * Paul Eggert provided the tzselect shell script as part of the timezone
2139 code. The shell script makes it easy to select the correct timezone
2142 * The implementation of the malloc family of functions is completely replaced
2143 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
2144 The implementation uses the mmap function (if available) and it is
2145 optimized for the use in multi threaded programs.
2147 * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
2148 functions. This new functionality is usable by specifying a special
2149 salt string and it is compatible with implementation on *BSD systems.
2151 * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
2152 `getsubopt' to handle second level command line options, `bsd_signal'
2153 to access BSD style `signal' functionality, the obsolete `regexp' style
2156 * the `lchown' function is available on system which support this
2159 * The implementation of the shadow password handling function was contributed
2162 * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
2164 * POSIX.1g support was added. The <sys/select.h> header is available,
2165 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
2166 implementation of `getaddrinfo'.
2170 * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
2172 * New header file <fstab.h> and new functions `getfsspec', `getfsent' and
2173 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
2175 * The new function `daemon' from 4.4 BSD is useful for server programs that
2176 want to put themselves in the background.
2178 * Joel Sherrill has contributed support for several standalone boards that
2179 run without an operating system.
2181 * `printf', `scanf' and friends now accept a `q' type modifier for long
2182 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
2184 * All of the code taken from BSD (notably most of the math and networking
2185 routines) has been updated from the BSD 4.4-Lite release.
2187 * The resolver code has been updated from the BIND-4.9.3-BETA9 release.
2189 * The new functions `getdomainname' and `setdomainname' fetch or change the
2190 YP/NIS domain name. These are system calls which exist on systems which
2193 * The time zone data files have been updated for the latest international
2196 * The SunRPC programs `portmap' and `rpcinfo' are now installed in
2197 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
2201 * The C library now includes support for Sun RPC, from Sun's free
2202 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
2203 are included. (There is still no support for YP.)
2205 * Tom Quinn has contributed a port of the C library to SGI machines running
2206 Irix 4 (mips-sgi-irix4).
2208 * The new `lockf' function is a simplified interface to the locking
2209 facilities of `fcntl', included for compatibility.
2211 * New time functions `timegm', `timelocal', and `dysize' for compatibility.
2213 * New header file <sys/timeb.h> and new function `ftime' for compatibility.
2215 * New header files <poll.h> and <sys/poll.h> and new function `poll' for
2218 * The error message printed by `assert' for a failed assertion now includes
2219 the name of the program (if using GNU ld) and the name of the calling
2220 function (with versions of GCC that support this).
2222 * The `psignal' function is now declared in <signal.h>, not <stdio.h>.
2224 * The library now includes the <sys/mman.h> header file and memory
2225 management functions `mmap', `munmap', `mprotect', `msync', and
2226 `madvise', on systems that support those facilities.
2228 * The interface for `mcheck' has changed slightly: the function called to
2229 abort the program when an allocation inconsistency is detected now takes
2230 an argument that indicates the type of failure. The new function
2231 `mprobe' lets you request a consistency check for a particular block at
2232 any time (checks are normally done only when you call `free' or `realloc'
2235 * It is now possible to easily cross-compile the C library, building on one
2236 system a library to run on another machine and/or operating system. All
2237 you need to do is set the variable `HOST_CC' in `configparms' to the
2238 native compiler for programs to run on the machine you are building on (a
2239 few generator programs are used on Unix systems); set `CC' to the
2242 * The new function `fexecve' (only implemented on the GNU system) executes
2243 a program file given a file descriptor already open on the file.
2247 * Brendan Kehoe has contributed most of a port to the DEC Alpha
2248 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
2250 * You can set the variable `libprefix' in `configparms' to specify a prefix
2251 to be prepended to installed library files; this makes it easy to install
2252 the GNU C library to be linked as `-lgnuc' or whatever.
2254 * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
2255 copies a limited number of characters from a string, and returns the
2256 address of the last character written.
2258 * You no longer need to check for whether the installed `stddef.h' is
2259 compatible with the GNU C library. configure now checks for you.
2261 * You can now define a per-stream `fileno' function to convert the
2262 stream's cookie into an integral file descriptor.
2264 * ``malloc (0)'' no longer returns a null pointer. Instead, it
2265 allocates zero bytes of storage, and returns a unique pointer which
2266 you can pass to `realloc' or `free'. The behavior is undefined if
2267 you dereference this pointer.
2269 * The C library now runs on Sony NEWS m68k machines running either
2270 NewsOS 3 or NewsOS 4.
2272 * The new `syscall' function is a system-dependent primitive function
2273 for invoking system calls. It has the canonical behavior on Unix
2274 systems, including unreliable return values for some calls (such as
2275 `pipe', `fork' and `getppid').
2277 * The error code `EWOULDBLOCK' is now obsolete; it is always defined
2278 to `EAGAIN', which is the preferred name. On systems whose kernels
2279 use two distinct codes, the C library now translates EWOULDBLOCK to
2280 EAGAIN in every system call function.
2284 * The GNU C Library Reference Manual is now distributed with the library.
2285 `make dvi' will produce a DVI file of the printed manual.
2286 `make info' will produce Info files that you can read on line using C-h i
2287 in Emacs or the `info' program.
2288 Please send comments on the manual to bug-glibc-manual@gnu.org.
2290 * The library now supports SVR4 on i386s (i386-unknown-sysv4).
2292 * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
2294 * Jason Merrill has contributed a port to the Sequent Symmetry running
2295 Dynix version 3 (i386-sequent-dynix).
2297 * The library has been ported to i386s running SCO 3.2.4 (also known as SCO
2298 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
2300 * New function `memory_warnings' lets you arrange to get warnings when
2301 malloc is running out of memory to allocate, like Emacs gives you.
2303 * The C library now contains the relocating allocator used in Emacs 19 for
2304 its editing buffers. This allocator (ralloc) minimizes allocation
2305 overhead and fragmentation by moving allocated regions around whenever it
2306 needs to. You always refer to a ralloc'd region with a "handle" (a
2307 pointer to a pointer--an object of type `void **').
2309 * There is a new `printf' format: `%m' gives you the string corresponding
2310 to the error code in `errno'.
2312 * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
2313 or `%[' conversion, but instead of filling in a fixed-sized buffer you
2314 pass, the `a' modifier says to fill in a `char **' you pass with a
2317 * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
2318 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
2319 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
2321 * `mkstemp' is a traditional Unix function to atomically create and open a
2322 uniquely-named temporary file.
2326 * The standard location for the file that says what the local timezone is
2327 has changed again. It is now `/usr/local/etc/localtime' (or more
2328 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
2330 * The distribution no longer contains any files with names longer than 14
2333 * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
2334 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
2336 * New functions `ttyslot' and `syslog' from 4.4 BSD.
2340 * The configuration process has changed quite a bit. The `configure'
2341 script is now used just like the configuration scripts for other GNU
2342 packages. The `sysdeps' directory hierarchy is much rearranged.
2343 The file `INSTALL' explains the new scheme in detail.
2345 * The header files no longer need to be processed into ANSI C and
2346 traditional C versions. There is just one set of files to install, and
2347 it will work with ANSI or old C compilers (including `gcc -traditional').
2349 * Brendan Kehoe and Ian Lance Taylor have ported the library to the
2350 MIPS DECStation running Ultrix 4.
2352 * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
2353 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
2354 made itself into a shared library.
2356 * Yet further improved support for the i386, running 4.3 BSD-like systems
2357 (such as Mach 3 with the Unix single-server), or System V.
2359 * New function `strncasecmp' to do case-insensitive string comparison
2360 with limited length.
2362 * New function `strsep' is a reentrant alternative to `strtok'.
2364 * New functions `scandir' and `alphasort' for searching directories.
2366 * New function `setenv' is a better interface to `putenv'.
2368 * Ian Lance Taylor has contributed an implementation of the SVID `ftw'
2369 function for traversing a directory tree.
2371 * The GNU obstack package is now also part of the C library.
2372 The new function `open_obstack_stream' creates a stdio stream that
2373 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
2374 formatted output directly to an obstack.
2376 * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
2377 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
2379 * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
2381 * The new functions `strfry' and `memfrob' do mysterious and wonderful
2382 things to your strings.
2384 * There are some new test programs: test-fseek, testmb, and testrand.
2386 * Some work has been done to begin porting the library to 4.4 BSD and Linux.
2387 These ports are not finished, but are a good starting place for really
2388 supporting those systems.
2390 * `/etc/localtime' is now the standard location for the file that says what
2391 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
2392 This follows the general principle that `/etc' is the place for all local
2393 configuration files.
2395 * The C library header files now use `extern "C"' when used by the C++
2396 compiler, so the C library should now work with C++ code.
2398 * The header file <bstring.h> is gone. <string.h> now declares bcopy,
2399 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
2402 * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
2403 function which uses the `merge sort' algorithm, and is said to be
2404 significantly faster than the old GNU `qsort' function. Merge sort is
2405 now the standard `qsort' function. The new algorithm can require a lot
2406 of temporary storage; so, the old sorting function is called when the
2407 required storage is not available.
2409 * The C library now includes Michael Glad's Ultra Fast Crypt, which
2410 provides the Unix `crypt' function, plus some other entry points.
2412 * The code and header files taken from 4.4 BSD have been updated with the
2413 latest files released from Berkeley.
