1 D-Bus 1.10.24 (UNRELEASED)
6 • When parsing dbus-daemon configuration, tell Expat not to use
7 cryptographic-quality entropy as a salt for its hash tables: we trust
8 the configuration files, so we are not concerned about algorithmic
9 complexity attacks via hash table collisions. This prevents
10 dbus-daemon --system from holding up the boot process (and causing
11 early-boot system services like systemd, logind, networkd to time
12 out) on entropy-starved embedded systems.
13 (fd.o #101858, Simon McVittie)
15 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
16 minimizing failed connections under heavy load
17 (fd.o #95264, Lennart Poettering) (backported from 1.11.4)
19 • Avoid a -Werror=declaration-after-statement build failure on Solaris
20 (fd.o #102145, Alan Coopersmith)
22 • When using the Monitoring interface, match messages' destinations
23 (fd.o #92074, Simon McVittie) (backported from 1.11.8)
25 D-Bus 1.10.22 (2017-07-27)
28 The “roof terrace” release.
32 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
33 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
35 • dbus_message_iter_open_container() no longer leaks memory if it runs out
36 of memory. (fd.o #101568, Simon McVittie)
38 • dbus_message_append_args_valist() no longer leaks memory if given an
39 unsupported type. This situation is still considered to be a programming
40 error which needs to be corrected by the user of libdbus.
41 (fd.o #101568, Simon McVittie)
43 • Wrap test-pending-call-disconnected with dbus-run-session so that it can
44 pass in environments that are not already running a D-Bus session bus,
45 fixing a build-time test regression in 1.10.20
46 (fd.o #101698, Simon McVittie)
48 • Ensure that tests fail if they would otherwise have tried to connect to
49 the real session bus (fd.o #101698, Simon McVittie)
51 • Make build-time tests cope with finding Python 3, but not Python 2
52 (fd.o #101716, Simon McVittie)
54 D-Bus 1.10.20 (2017-06-29)
57 The “suggesting a delivery gone horribly wrong” release.
61 • Fix a reference leak when blocking on a pending call on a connection
62 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
64 • Don't put timestamps in the Doxygen-generated documentation, for
65 closer-to-reproducible builds (fd.o #100692, Simon McVittie)
67 • Avoid an assertion failure when connecting to a semicolon-separated
68 series of addresses, one of which fails (fd.o #101257, Simon McVittie)
72 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
73 (fd.o #100715, Simon McVittie)
75 D-Bus 1.10.18 (2017-04-05)
78 The “can't handle a self-referential paradox” release.
82 • Re-order dbus-daemon startup so that on SELinux systems, the thread
83 that reads AVC notifications retains the ability to write to the
84 audit log (fd.o #92832, Debian #857660; Laurent Bigonville)
86 • Fix a harmless read overflow and some memory leaks in a unit test
87 (fd.o #100568, Philip Withnall)
89 D-Bus 1.10.16 (2017-02-16)
92 The “super digging powers” release.
94 The fixes in this release are arguably security fixes, but if they
95 affect you, please take this opportunity to rethink how you are
100 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
101 stable and Debian testing in addition to the older Ubuntu that is
102 the default (fd.o #98889, Simon McVittie)
106 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
107 allow an attacker to overwrite a file named "nonce", in a directory
108 that the user running dbus-daemon can write, with a random value
109 known only to the user running dbus-daemon. This is unlikely to be
110 exploitable in practice, particularly since the nonce-tcp transport
111 is really only useful on Windows.
113 On Unix systems we strongly recommend using only the unix: and systemd:
114 transports, together with EXTERNAL authentication. These are the only
115 transports and authentication mechanisms enabled by default.
117 (fd.o #99828, Simon McVittie)
119 • Avoid symlink attacks in the "embedded tests", which are not enabled
120 by default and should never be enabled in production builds of dbus.
121 (fd.o #99828, Simon McVittie)
123 D-Bus 1.10.14 (2016-11-28)
126 The “Well, other bands know more than three chords” release.
130 • Work around an undesired effect of the fix for CVE-2014-3637
131 (fd.o #80559), in which processes that frequently send fds, such as
132 logind during a flood of new PAM sessions, can get disconnected for
133 continuously having at least one fd "in flight" for too long;
134 dbus-daemon interprets that as a potential denial of service attack.
135 The workaround is to disable that check for uid 0 process such as
136 logind, with a message in the system log. The bug remains open while
137 we look for a more general solution.
138 (fd.o #95263, LP#1591411; Simon McVittie)
140 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
141 was disabled at compile time. That test is not expected to work
142 in that configuration. (fd.o #98665, Simon McVittie)
144 D-Bus 1.10.12 (2016-10-10)
147 The “not excessively inhospitable” release.
151 • Do not treat ActivationFailure message received from root-owned systemd
152 name as a format string. In principle this is a security vulnerability,
153 but we do not believe it is exploitable in practice, because only
154 privileged processes can own the org.freedesktop.systemd1 bus name, and
155 systemd does not appear to send activation failures that contain "%".
157 Please note that this probably *was* exploitable in dbus versions
158 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
159 the time was only thought to be a denial of service vulnerability
160 (CVE-2015-0245). If you are still running one of those versions,
161 patch or upgrade immediately.
163 (fd.o #98157, Simon McVittie)
167 • Harden dbus-daemon against malicious or incorrect ActivationFailure
168 messages by rejecting them if they do not come from a privileged
169 process, or if systemd activation is not enabled
170 (fd.o #98157, Simon McVittie)
172 • Avoid undefined behaviour when setting reply serial number without going
173 via union DBusBasicValue (fd.o #98035, Marc Mutz)
175 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
177 D-Bus 1.10.10 (2016-08-15)
180 The “tungsten door” release.
184 • On Linux, when dbus-daemon is run with reduced susceptibility to the
185 OOM killer (typically via systemd), do not let child processes inherit
186 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
188 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
189 contains a semicolon (fd.o #94746, Thiago Macieira)
191 • Fix memory leaks and thread safety in subprocess starting on Windows
192 (fd.o #95191, Ralf Habacker)
194 • Do not require systemd to have a service file if using it for activation
195 (fd.o #93194; Simon McVittie; backport from 1.11.0)
197 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
198 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
200 • In tests that exercise correct handling of crashing D-Bus services,
201 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
203 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
205 • update-activation-environment: produce better diagnostics on error
206 (fd.o #96653, Simon McVittie)
208 • Don't fail the build with an unused const variable warning under gcc 6
209 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
211 • Merge dbus-1.10-ci branch, containing backports from 1.11.0 in build/test
212 code to support continuous integration (fd.o #93194, Simon McVittie)
214 · Avoid -Wunused-label when compiling with libselinux but no libaudit
215 · In development builds, allow OOM tests to be disabled as documented
216 · Accept and ignore the --tap argument in all "embedded tests", and run
217 all automated tests with that argument for better diagnostics
218 · Fix the systemd activation test under CMake by installing the required
220 · In Automake, fix shell syntax for installcheck-local with no DESTDIR
221 · In Automake, don't try to run manual tests in installcheck
222 · In CMake, don't run manual-tcp test as an automated test
223 · Add travis-ci.org build machinery
225 D-Bus 1.10.8 (2016-03-07)
228 The “digestive biscuits” release.
232 • Enable "large file support" on systems where it exists: dbus-daemon
233 is not expected to open large files, but it might need to stat files
234 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
236 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
237 which might result in a pedantic C compiler not copying the entire contents
238 of a DBusMessageIter; statically assert that this is not an ABI change
239 in practice (fd.o #94136, Simon McVittie)
241 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
242 (fd.o #94244, Dmitri Iouchtchenko)
244 • Correctly report test failures in C tests from run-test.sh
245 (fd.o #93379; amit tewari, Simon McVittie)
247 • When tests are enabled, run all the marshal-validate tests, not just
248 the even-numbered ones (fd.o #93908, Nick Lewycky)
250 • Correct the expected error from one marshal-validate test, which was
251 previously not run due to the above bug (fd.o #93908, Simon McVittie)
253 D-Bus 1.10.6 (2015-12-01)
256 The “marzipan beetles” release.
260 • On Unix when running tests as root, don't assert that root and
261 the dbus-daemon user can still call UpdateActivationEnvironment;
262 assert that those privileged users can call BecomeMonitor instead
263 (fd.o #93036, Simon McVittie)
265 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
268 • On Windows Autotools builds, don't run tests that rely on
269 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
271 D-Bus 1.10.4 (2015-11-17)
274 The “Frostburn Canyon” release.
278 • GetConnectionCredentials, GetConnectionUnixUser and
279 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
280 will now return details of the dbus-daemon itself. This is required
281 to be able to call SetEnvironment on systemd.
282 (fd.o #92857, Jan Alexander Steffens)
286 • Make UpdateActivationEnvironment always fail with AccessDenied on the
287 system bus. Previously, it was possible to configure it so root could
288 call it, but the environment variables were not actually used,
289 because the launch helper would discard them.
290 (fd.o #92857, Jan Alexander Steffens)
292 • On Unix with --systemd-activation on a user bus, make
293 UpdateActivationEnvironment pass on its arguments to systemd's
294 SetEnvironment method, solving inconsistency between the environments
295 used for traditional activation and systemd user-service activation.
296 (fd.o #92857, Jan Alexander Steffens)
298 • On Windows, don't crash if <syslog/> or --syslog is used
299 (fd.o #92538, Ralf Habacker)
301 • On Windows, fix a memory leak when setting a DBusError from a Windows
302 error (fd.o #92721, Ralf Habacker)
304 • On Windows, don't go into infinite recursion if we abort the process
305 with backtraces enabled (fd.o #92721, Ralf Habacker)
307 • Fix various failing tests, variously on Windows and cross-platform:
308 · don't test system.conf features (users, groups) that only make sense
309 on the system bus, which is not supported on Windows
310 · don't call _dbus_warn() when we skip a test, since it is fatal
311 · fix computation of expected <standard_session_servicedirs/>
312 · when running TAP tests, translate newlines to Unix format, fixing
313 cross-compiled tests under Wine on Linux
314 · don't stress-test refcounting under Wine, where it's really slow
315 · stop assuming that a message looped-back to the test will be received
317 · skip some system bus tests on Windows since they make no sense there
318 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
320 D-Bus 1.10.2 (2015-10-26)
323 The “worst pies in London” release.
327 • Correct error handling for activation: if there are multiple attempts
328 to activate the same service and it fails immediately, the first attempt
329 would get the correct reply, but the rest would time out. We now send
330 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
332 • If BecomeMonitor is called with a syntactically invalid match rule,
333 don't crash with an assertion failure, fixing a regression in 1.9.10.
334 This was not exploitable as a denial of service, because the check
335 for a privileged user is done first. (fd.o #92298, Simon McVittie)
337 • On Linux with --enable-user-session, add the bus address to the
338 environment of systemd services for better backwards compatibility
339 (fd.o #92612, Jan Alexander Steffens)
341 • On Windows, fix the logic for replacing the installation prefix
342 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
344 • On Windows, if installed in the conventional layout with ${prefix}/etc
345 and ${prefix}/share, use relative paths between bus configuration files
346 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
348 • Make more of the regression tests pass in Windows builds (fd.o #92538,
351 D-Bus 1.10.0 (2015-08-25)
356 This is a new stable branch, recommended for use in OS distributions.
360 • distribute test/tap-test.sh.in, even if the tarball was built without
361 tests enabled (fd.o #91684, Simon McVittie)
362 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
364 Summary of major changes since 1.8.0:
366 • The basic setup for the well-known system and session buses is
367 now done in read-only files in ${datadir} (normally /usr/share).
368 See the NEWS entry for 1.9.18 for details.
370 • AppArmor integration has been merged, with features similar to the
371 pre-existing SELinux integration. It is mostly compatible with the
372 patches previously shipped by Ubuntu, with one significant change:
373 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
374 by GetConnectionCredentials and was not included.
376 • The --enable-user-session configure option can be enabled
377 by OS integrators intending to use systemd to provide a session bus
378 per user (in effect, treating all concurrent graphical and non-graphical
379 login sessions as one large session).
381 • The new listenable address mode "unix:runtime=yes" listens on
382 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
383 user session. libdbus and "dbus-launch --autolaunch" will connect to
384 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
387 • All executables are now dynamically linked to libdbus-1.
388 Previously, some executables, most notably dbus-daemon, were statically
389 linked to a specially-compiled variant of libdbus. This results in
390 various private functions in the _dbus namespace being exposed by the
391 shared library. These are not API, and must not be used outside
392 the dbus source tree.
394 • On platforms with ELF symbol versioning, all public symbols
395 are versioned LIBDBUS_1_3.
399 • org.freedesktop.DBus.GetConnectionCredentials returns
400 LinuxSecurityLabel where supported
401 • org.freedesktop.DBus.Monitoring interface (privileged)
402 · BecomeMonitor method supersedes match rules with eavesdrop=true,
403 which are now deprecated
404 • org.freedesktop.DBus.Stats interface (semi-privileged)
405 · now enabled by default
406 · new GetAllMatchRules method
407 • org.freedesktop.DBus.Verbose interface (not normally compiled)
408 · toggles the effect of DBUS_VERBOSE
413 • dbus-update-activation-environment
415 New optional dependencies:
417 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
418 • Complete documentation requires Ducktype and yelp-tools
419 • Full test coverage requires GLib 2.36 and PyGI
420 • AppArmor integration requires libapparmor and optionally libaudit
422 Dependencies removed:
426 D-Bus 1.9.20 (2015-08-06)
429 The “Remember Tomorrow” release.
431 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
436 • Don't second-guess what the ABI of poll() is, allowing it to be used
437 on Integrity RTOS and other unusual platforms (fd.o #90314;
438 Rolland Dudemaine, Simon McVittie)
440 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
441 both enabled (fd.o #89225, Simon McVittie)
443 • Log audit events for AppArmor/SELinux policy violations whenever
444 we have CAP_AUDIT_WRITE, even if not the system bus
445 (fd.o #83856, Laurent Bigonville)
447 D-Bus 1.9.18 (2015-07-21)
450 The “Pirate Elite” release.
452 Configuration changes:
454 • The basic setup for the well-known system and session buses is now done
455 in read-only files in ${datadir}, moving a step closer to systems
456 that can operate with an empty /etc directory. In increasing order
459 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
460 the default message policies.
461 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
462 dbus still installs a trivial version of each, for documentation
463 purposes; putting configuration directives in these files is deprecated.
464 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
465 to install "drop-in" configuration snippets (any packages
466 using those directories should explicitly depend on at least this
468 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
469 or third-party software to install "drop-in" configuration snippets
470 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
473 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
474 and "s*" refers to either system or session as appropriate.
476 (fd.o #89280, Dimitri John Ledkov)
480 • Fix a memory leak when GetConnectionCredentials() succeeds
481 (fd.o #91008, Jacek Bukarewicz)
483 • Ensure that dbus-monitor does not reply to messages intended for others,
484 resulting in its own disconnection (fd.o #90952, Simon McVittie)
486 D-Bus 1.9.16 (2015-05-14)
489 The “titanium barns” release.
493 • Automake 1.13 is now required when compiling from git or modifying
498 • On Unix platforms, change the default configuration for the session bus
499 to only allow EXTERNAL authentication (secure kernel-mediated
500 credentials-passing), as was already done for the system bus.
502 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
503 unpredictable pseudo-random numbers.
505 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
506 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
507 NFS or similar, you will need to reconfigure the session bus to accept
508 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
511 (fd.o #90414, Simon McVittie)
513 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
514 transport, UUIDs or any other reason, fail if we cannot obtain entropy
515 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
516 occurs, instead of silently falling back to low-entropy pseudorandom
517 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
521 • Add dbus_message_iter_get_element_count()
522 (fd.o #30350; Christian Dywan, Simon McVittie)
524 • Introduce new internal DBusSocket and DBusPollable types so we can
525 stop treating the Windows SOCKET type as if it was int. DBusSocket
526 is specifically a socket, cross-platform. DBusPollable is whatever
527 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
528 (fd.o #89444; Ralf Habacker, Simon McVittie)
530 • All regression tests now output TAP <https://testanything.org/>
531 (fd.o #89846, Simon McVittie)
533 • Internal APIs consistently use signed values for timestamps
534 (fd.o #18494, Peter McCurdy)
536 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
537 (fd.o #88812, Simon McVittie)
539 • Clean up a lot of compiler warnings
540 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
544 • Add locking to DBusCounter's reference count and notify function
545 (fd.o #89297, Adrian Szyndela)
547 • Ensure that DBusTransport's reference count is protected by the
548 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
550 • Correctly release DBusServer mutex before early-return if we run out
551 of memory while copying authentication mechanisms (fd.o #90021,
554 • Make dbus-test-tool and dbus-update-activation-environment portable
555 to Windows (fd.o #90089, Ralf Habacker)
557 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
558 Ralf Habacker, Simon McVittie)
560 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
563 • Clean up some memory and fd leaks in test code and tools
564 (fd.o #90021, Ralf Habacker)
566 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
567 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
569 • CMake generates a versioned shared library even if the revision is 0,
570 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
572 D-Bus 1.9.14 (2015-03-02)
575 The “don't stand in the poison cloud” release.
579 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
580 were previously linked to a static version of libdbus.
582 • The tests no longer require dbus-glib in order to exercise the libdbus
583 shared library; they are always linked to libdbus now.
585 Build-time configuration:
587 • The new --enable-user-session option, off by default, can be enabled
588 by OS integrators intending to use systemd to provide a session bus
589 per user (in effect, treating all concurrent graphical and non-graphical
590 login sessions as one large session)
594 • All executables are now linked dynamically to libdbus.
595 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
597 • On platforms that support them (GNU libc and possibly others),
598 libdbus now has versioned symbols for its public API.
599 All public symbols (visible in the header files) are currently
600 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
601 dbus_internal have a version that changes with each release, and
602 must not be used by applications. (also fd.o #83115)
604 • New listenable address mode "unix:runtime=yes" which listens on
605 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
606 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
608 • Add optional systemd units for a per-user bus listening on
609 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
611 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
612 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
615 • New dbus-update-activation-environment tool uploads environment
616 variables to "dbus-daemon --session" and optionally "systemd --user",
617 primarily as a way to keep the per-user bus compatible with
618 distributions' existing X11 login scripts (also fd.o #61301)
620 • <includedir/> elements in dbus-daemon configuration are now silently
621 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
623 • Add microsecond-resolution timestamps to the default output of
624 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
628 • Fix a race condition in the 'monitor' test introduced in 1.9.10
629 (fd.o #89222, Simon McVittie)
631 D-Bus 1.9.12 (2015-02-19)
634 The “monster lasagna” release.
638 • Ducktype and yelp-tools are now required to build complete documentation
639 (they are optional for normal builds).
643 • D-Bus Specification version 0.26
644 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
645 · document the BecomeMonitor method
647 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
648 (fd.o #89041; Tyler Hicks, Simon McVittie)
650 • On Linux, add support for AppArmor mediation of message sending and
651 receiving and name ownership (paralleling existing SELinux mediation
652 support), and eavesdropping (a new check, currently AppArmor-specific)
653 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
655 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
656 that have printable ASCII contents; we previously only did this for
657 unterminated bytestrings (fd.o #89109, Simon McVittie)
659 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
661 • On Windows, add WindowsSID to GetConnectionCredentials
662 (fd.o #54445, Ralf Habacker)
664 • Improve clarity of dbus-monitor --profile output and add more columns
665 (fd.o #89165, Ralf Habacker)
667 • Add a man page for dbus-test-tool, and build it under CMake as well
668 as Autotools (fd.o#89086, Simon McVittie)
670 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
671 to control it at runtime, overriding the DBUS_VERBOSE environment variable
672 (fd.o #88896, Ralf Habacker)
676 • Reduce the number of file descriptors used in the fd-passing test,
677 avoiding failure under the default Linux fd limit, and automatically
678 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
680 D-Bus 1.9.10 (2015-02-09)
683 The “sad cyborgs” release.
685 Security fixes merged from 1.8.16:
687 • Do not allow non-uid-0 processes to send forged ActivationFailure
688 messages. On Linux systems with systemd activation, this would
689 allow a local denial of service: unprivileged processes could
690 flood the bus with these forged messages, winning the race with
691 the actual service activation and causing an error reply
692 to be sent back when service auto-activation was requested.
693 This does not prevent the real service from being started,
694 so the attack only works while the real service is not running.
695 (CVE-2015-0245, fd.o #88811; Simon McVittie)
699 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
700 similar tools receive messages without altering the security properties
701 of the system bus, by calling the new BecomeMonitor method on a
702 private connection. This bypasses the normal <allow> and <deny> rules
703 entirely, so to preserve normal message-privacy assumptions, only root
704 is allowed to do this on the system bus. Restricted environments,
705 such as Linux with LSMs, should lock down access to the Monitoring
706 interface. (fd.o #46787, Simon McVittie)
708 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
709 dbus-daemon supports it and access permissions allow it.
710 It still supports the previous approach ("eavesdropping" match rules)
711 for compatibility with older bus daemons. (fd.o #46787, Simon)
713 • dbus-monitor can now log the message stream as binary data for later
714 analysis, with either no extra framing beyond the normal D-Bus headers,
715 or libpcap-compatible framing treating each D-Bus message
716 as a captured packet. (fd.o #46787, Simon)
720 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
722 • On Unix, forcibly terminate regression tests after 60 seconds to
723 prevent them from blocking continuous integration frameworks
726 D-Bus 1.9.8 (2015-02-03)
729 The “all the types of precipitation” release.
733 • full test coverage now requires GLib 2.36
734 • full test coverage now requires PyGI (PyGObject 3,
735 "import gi.repository.GObject") instead of the
736 obsolete PyGObject 2 ("import gobject")
740 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
742 • better regression test coverage, including systemd activation
743 (fd.o #57952, #88810; Simon McVittie)
747 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
748 turned off (fd.o #88808, Simon McVittie)
750 • TCP sockets on Windows no longer fail to listen approximately 1 time
751 in 256, caused by a logic error that should have always made it fail but
752 was mitigated by incorrect endianness for the port number
753 (fd.o #87999, Ralf Habacker)
755 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
757 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
758 previous 64, completing a previous fix which only worked under
759 Autotools (fd.o #71297, Ralf Habacker)
761 • on Windows, if the IP family is unspecified only use IPv4,
762 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
764 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
766 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
768 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
771 D-Bus 1.9.6 (2015-01-05)
774 The “I do have a bread knife” release.
778 • Do not allow calls to UpdateActivationEnvironment from uids other than
779 the uid of the dbus-daemon. If a system service installs unsafe
780 security policy rules that allow arbitrary method calls
781 (such as CVE-2014-8148) then this prevents memory consumption and
782 possible privilege escalation via UpdateActivationEnvironment.
784 We believe that in practice, privilege escalation here is avoided
785 by dbus-daemon-launch-helper sanitizing its environment; but
786 it seems better to be safe.
788 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
789 on object paths other than /org/freedesktop/DBus. Some system services
790 install unsafe security policy rules that allow arbitrary method calls
791 to any destination, method and interface with a specified object path;
792 while less bad than allowing arbitrary method calls, these security
793 policies are still harmful, since dbus-daemon normally offers the
794 same API on all object paths and other system services might behave
799 • Add missing initialization so GetExtendedTcpTable doesn't crash on
800 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
802 D-Bus 1.9.4 (2014-11-24)
805 The “extra-sturdy caramel” release.
809 • Partially revert the CVE-2014-3639 patch by increasing the default
810 authentication timeout on the system bus from 5 seconds back to 30
811 seconds, since this has been reported to cause boot regressions for
812 some users, mostly with parallel boot (systemd) on slower hardware.
814 On fast systems where local users are considered particularly hostile,
815 administrators can return to the 5 second timeout (or any other value
816 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
819 <limit name="auth_timeout">5000</limit>
822 (fd.o #86431, Simon McVittie)
824 • Add a message in syslog/the Journal when the auth_timeout is exceeded
825 (fd.o #86431, Simon McVittie)
827 • Send back an AccessDenied error if the addressed recipient is not allowed
828 to receive a message (and in builds with assertions enabled, don't
829 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
831 D-Bus 1.9.2 (2014-11-10)
834 The “structurally unsound flapjack” release.
838 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
839 so that CVE-2014-3636 part A cannot exhaust the system bus'
840 file descriptors, completing the incomplete fix in 1.8.8.
841 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
845 • D-Bus Specification version 0.25
846 · new value 'const' for EmitsChangedSignal annotation
847 (fd.o #72958, Lennart Poettering)
848 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
849 (fd.o #83449; Lennart Poettering, Simon McVittie)
850 · annotate table of types with reserved/basic/container, and for
851 basic types, fixed/string-like
852 · clarify arbitrary limits by quoting them in mebibytes
854 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
855 (fd.o #83449, Simon McVittie)
857 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
858 useful for debugging and performance testing:
859 · dbus-test-tool spam: send repeated messages
860 · dbus-test-tool echo: send an empty reply for all method calls
861 · dbus-test-tool black-hole: do not reply to method calls
862 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
864 • Add support for process ID in credentials-passing on NetBSD
865 (fd.o #69702, Patrick Welche)
867 • Add an example script to find potentially undesired match rules
868 (fd.o #84598, Alban Crequy)
870 • Document the central assumption that makes our use of credentials-passing
871 secure (fd.o #83499, Simon McVittie)
873 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
874 and add some links to GDBus and QtDBus documentation (fd.o #25140,
879 • Use a less confusing NoReply message when disconnected with a reply pending
880 (fd.o #76112, Simon McVittie)
882 • Make the .pc file relocatable by letting pkg-config do all variable
883 expansion itself (fd.o #75858, Руслан Ижбулатов)
885 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
886 (fd.o #85563, Patrick Welche)
888 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
890 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
891 do not lose the exec() errno (fd.o #24821, Simon McVittie)
893 • Do not fail the tests if a parent process has leaked non-close-on-exec
894 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
896 • Do not fail the tests on Unix platforms with incomplete
897 credentials-passing support, but do fail if we can't pass credentials
898 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
899 (fd.o #69702, Simon McVittie)
901 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
902 when building with cmake, and expand test coverage there
903 (fd.o #73689; Ralf Habacker, Simon McVittie)
905 D-Bus 1.9.0 (2014-10-01)
908 The “tiered cheeses” release.
912 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
913 requires either the libsystemd or libsd-daemon shared library, dropping the
914 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
916 Build-time configuration changes:
918 • The Stats interface is now enabled by default, and locked-down to
919 root-only on the system bus. Configure with --disable-stats
920 to disable it altogether on memory- or disk-constrained systems,
921 or see ${docdir}/examples/ to open it up to non-root users on the
922 system bus or restrict access on the session bus.
923 (fd.o #80759; Simon McVittie, Alban Crequy)
925 • The CMake build system now builds the same shared library name as Autotools
926 on at least Linux and Windows:
927 - on Linux (and perhaps other Unix platforms), it previously built
928 libdbus-1.so, but now builds libdbus-1.so.3.* with development
929 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
930 - on Windows, it previously built either libdbus-1.dll (release) or
931 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
932 libdbus-1.dll for compatibility with older applications.
933 (fd.o #74117, Ralf Habacker)
937 • D-Bus Specification version 0.24
938 · document how to quote match rules (fd.o #24307, Simon McVittie)
939 · explicitly say that most message types never expect a reply
940 regardles of whether they have NO_REPLY_EXPECTED
941 (fd.o #75749, Simon McVittie)
943 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
944 initial latency (fd.o #75544, Matt Hoosier)
946 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
947 (fd.o #69702, Patrick Welche)
949 • in dbus-monitor, print more information about file descriptors
950 (fd.o #80603, Alban Crequy)
952 • do not install system bus configuration if built for Windows
953 (fd.o #83583; Ralf Habacker, Simon McVittie)
955 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
957 • Add a regression test for file descriptor passing (fd.o #83622,
962 • fix an incorrect error message if a Unix socket path is too long
963 (fd.o #73887, Antoine Jacoutot)
965 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
966 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
968 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
969 in ps(1) (fd.o #69716, Chengwei Yang)
971 • avoid calling poll() with timeout < -1, which is considered invalid
972 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
974 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
975 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
976 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
978 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
980 • Documentation improvements
981 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
983 • in dbus-monitor, do not leak file descriptors that we have monitored
984 (fd.o #80603, Alban Crequy)
986 • Set the close-on-exec flag for the inotify file descriptor, even
987 if built with CMake or older libc (fd.o #73689, Simon McVittie)
989 • Remove some LGPL code from the Windows dbus-daemon
990 (fd.o #57272, Ralf Habacker)
992 D-Bus 1.8.8 (2014-09-16)
995 The "smashy smashy egg man" release.
999 • Do not accept an extra fd in the padding of a cmsg message, which
1000 could lead to a 4-byte heap buffer overrun.
1001 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1003 • Reduce default for maximum Unix file descriptors passed per message
1004 from 1024 to 16, preventing a uid with the default maximum number of
1005 connections from exhausting the system bus' file descriptors under
1006 Linux's default rlimit. Distributors or system administrators with a
1007 more restrictive fd limit may wish to reduce these limits further.
1009 Additionally, on Linux this prevents a second denial of service
1010 in which the dbus-daemon can be made to exceed the maximum number
1011 of fds per sendmsg() and disconnect the process that would have
1013 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1015 • Disconnect connections that still have a fd pending unmarshalling after
1016 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1017 removing the possibility of creating an abusive connection that cannot be
1018 disconnected by setting up a circular reference to a connection's
1020 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1022 • Reduce default for maximum pending replies per connection from 8192 to 128,
1023 mitigating an algorithmic complexity denial-of-service attack
1024 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1026 • Reduce default for authentication timeout on the system bus from
1027 30 seconds to 5 seconds, avoiding denial of service by using up
1028 all unauthenticated connection slots; and when all unauthenticated
1029 connection slots are used up, make new connection attempts block
1030 instead of disconnecting them.
1031 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1035 • Check for libsystemd from systemd >= 209, falling back to
1036 the older separate libraries if not found (Umut Tezduyar Lindskog,
1039 • On Linux, use prctl() to disable core dumps from a test executable
1040 that deliberately raises SIGSEGV to test dbus-daemon's handling
1041 of that condition (fd.o #83772, Simon McVittie)
1043 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
1046 • Improve documentation for running tests on Windows (fd.o #41252,
1049 D-Bus 1.8.6 (2014-06-02)
1054 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1055 the message. This prevents an attack in which a malicious client can
1056 make dbus-daemon disconnect a system service, which is a local
1058 (fd.o #80163, CVE-2014-3532; Alban Crequy)
1060 • Track remaining Unix file descriptors correctly when more than one
1061 message in quick succession contains fds. This prevents another attack
1062 in which a malicious client can make dbus-daemon disconnect a system
1064 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
1065 Simon McVittie, Alban Crequy)
1069 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
1070 attach to a session, kill the dbus-daemon as intended
1071 (fd.o #74698, Роман Донченко)
1073 D-Bus 1.8.4 (2014-06-10)
1078 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1079 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1080 Additionally, in highly unusual environments the same flaw could lead to
1081 a side channel between processes that should not be able to communicate.
1082 (CVE-2014-3477, fd.o #78979)
1084 D-Bus 1.8.2 (2014-04-30)
1087 The “nobody wants red” release.
1091 • in the CMake build system, add some hints for Linux users cross-compiling
1092 Windows D-Bus binaries to be able to run tests under Wine
1093 (fd.o #41252, Ralf Habacker)
1095 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
1099 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
1100 to /var/lib/dbus/machine-id instead of generating an entirely new ID
1101 (fd.o #77941, Simon McVittie)
1103 • if dbus-launch receives an X error very quickly, do not kill
1104 unrelated processes (fd.o #74698, Роман Донченко)
1106 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
1107 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
1109 • cope with \r\n newlines in regression tests, since on Windows,
1110 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
1112 D-Bus 1.8.0 (2014-01-20)
1115 The “Wolverine distrusts my printer” release.
1117 This starts a new stable branch. The 1.6.x branch is now considered to be
1118 outdated, and will only receive fixes for serious bugs such as security
1119 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1120 are unlikely to get any more releases, but if distributors still need to
1121 support them, please share security patches via upstream.
1123 Summary of changes since 1.6.x:
1125 • libdbus always behaves as if dbus_threads_init_default() had been called
1126 (thread-safety by default)
1127 • new dbus-run-session tool, replacing certain misuses of dbus-launch
1128 • dbus-monitor can talk to outdated versions of dbus-daemon again
1129 • new org.freedesktop.DBus.GetConnectionCredentials method
1130 • GetConnectionUnixProcessID also works correctly on Windows, returning
1131 the Windows process ID
1132 • GetConnectionWindowsSID returns the correct SID on Windows
1133 • expat is required, libxml2 can no longer be used as a substitute
1134 • the userDB cache is required, and cannot be disabled
1135 • a 64-bit integer type (either int, long, long long or _int64) is required
1136 • better systemd-journald integration on Linux
1137 • fixed long-standing fd and array leaks when failing to parse a message
1138 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
1139 when using certain object-path allocation patterns, notably in Avahi
1140 • better defaults for Windows support
1141 • better CMake support
1142 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
1143 • the source language for the man pages is now Docbook XML
1145 Enhancements since 1.7.10:
1147 • Enhance the CMake build system to check for GLib and compile/run
1148 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
1152 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
1155 • fix compilation of systemd journal support on older systemd versions where
1156 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
1158 • fix compilation on older MSVC versions by including stdlib.h
1159 (fd.o #73455, Ralf Habacker)
1161 • Allow <allow_anonymous/> to appear in an included configuration file
1162 (fd.o #73475, Matt Hoosier)
1164 Test behaviour changes since 1.7.10:
1166 • If the tests crash with an assertion failure, they no longer default to
1167 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
1168 environment if you want the old behaviour.
1170 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
1171 can be run with an external dbus-daemon by setting
1172 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
1173 an unusually-configured dbus-daemon are skipped.
1175 D-Bus 1.7.10 (2014-01-06)
1178 The “weighted companion cube” release.
1180 This is a release candidate for D-Bus 1.8.

1204 active services (fd.o #71526, Radoslaw Pajak)
1206 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
1208 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
1210 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
1211 and DBUS__SEND_MSG are numerically equal to their values in the
1212 reference policy (fd.o #88719, osmond sun)
1214 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
1215 (fd.o #71366, Matt Fischer)
1217 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
1218 winsock2.h (fd.o #71405, Matt Fischer)
1220 • do not return failure from _dbus_read_nonce() with no error set,
1221 preventing a potential crash (fd.o #72298, Chengwei Yang)
1223 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
1224 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
1226 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
1227 which doesn't do anything anyway on at least Linux and FreeBSD
1228 (fd.o #69492, Simon McVittie)
1230 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
1231 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
1232 for credentials more correctly (fd.o #69492, Simon McVittie)
1234 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
1235 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
1238 • refresh cached policy rules for existing connections when bus
1239 configuration changes (fd.o #39463, Chengwei Yang)
1241 D-Bus 1.7.8 (2013-11-01)
1244 The “extreme hills” release.
1248 • If systemd support is enabled, libsystemd-journal is now required.
1252 • When activating a non-systemd service under systemd, annotate its
1253 stdout/stderr with its bus name in the Journal. Known limitation:
1254 because the socket is opened before forking, the process will still be
1255 logged as if it had dbus-daemon's process ID and user ID.
1256 (fd.o #68559, Chengwei Yang)
1258 • Document more configuration elements in dbus-daemon(1)
1259 (fd.o #69125, Chengwei Yang)
1263 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
1264 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
1266 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
1267 disallowed method calls to the audit log, fixing a regression in 1.7.6
1268 (fd.o #49062, Colin Walters)
1270 • path_namespace='/' in match rules incorrectly matched nothing; it
1271 now matches everything. (fd.o #70799, Simon McVittie)
1273 D-Bus 1.7.6 (2013-10-09)
1276 The “CSI Shrewsbury” release.
1278 Build-time configuration changes:
1280 • Directory change notification via dnotify on Linux is no longer
1281 supported; it hadn't compiled successfully since 2010 in any case.
1282 If you don't have inotify (Linux) or kqueue (*BSD), you will need
1283 to send SIGHUP to the dbus-daemon when its configuration changes.
1284 (fd.o #33001, Chengwei Yang)
1286 • Compiling with --disable-userdb-cache is no longer supported;
1287 it didn't work since at least 2008, and would lead to an extremely
1288 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
1291 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
1292 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
1293 with the Autotools build system. (fd.o #66142, Chengwei Yang)
1295 • --with-valgrind=auto enables Valgrind instrumentation if and only if
1296 valgrind headers are available. The default is still --with-valgrind=no.
1297 (fd.o #56925, Simon McVittie)
1301 • Platforms with no 64-bit integer type are no longer supported.
1302 (fd.o #65429, Simon McVittie)
1304 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
1306 • Full test coverage no longer requires dbus-glib, although the tests do not
1307 exercise the shared library (only a static copy) if dbus-glib is missing.
1308 (fd.o #68852, Simon McVittie)
1312 • D-Bus Specification 0.22
1313 · Document GetAdtAuditSessionData() and
1314 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
1315 · Fix example .service file (fd.o #66481, Chengwei Yang)
1316 · Don't claim D-Bus is "low-latency" (lower than what?), just
1317 give factual statements about it supporting async use
1318 (fd.o #65141, Justin Lee)
1319 · Document the contents of .service files, and the fact that
1320 system services' filenames are constrained
1321 (fd.o #66608; Simon McVittie, Chengwei Yang)
1323 • Be thread-safe by default on all platforms, even if
1324 dbus_threads_init_default() has not been called. For compatibility with
1325 older libdbus, library users should continue to call
1326 dbus_threads_init_default(): it is harmless to do so.
1327 (fd.o #54972, Simon McVittie)
1329 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
1331 • New API: dbus_setenv(), a simple wrapper around setenv().
1332 Note that this is not thread-safe. (fd.o #39196, Simon)
1334 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
1335 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
1336 (connect to a given bus, like dbus-monitor --address=ADDRESS).
1337 dbus-send --address still exists for backwards compatibility,
1338 but is no longer documented. (fd.o #48816, Andrey Mazo)
1341 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
1346 • Avoid an infinite busy-loop if a signal interrupts waitpid()
1347 (fd.o #68945, Simon McVittie)
1349 • Clean up memory for parent nodes when objects are unexported
1350 (fd.o #60176, Thomas Fitzsimmons)
1352 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
1353 documented. Previously, it assumed its second parameter was TRUE.
1354 (fd.o #69165, Chengwei Yang)
1356 • Escape addresses containing non-ASCII characters correctly
1357 (fd.o #53499, Chengwei Yang)
1359 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
1361 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
1362 (fd.o #65923, Chengwei Yang)
1364 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
1365 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
1367 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
1368 that was never va_start()ed (fd.o #66300, Chengwei Yang)
1370 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
1372 • fix a regression test on platforms with strict alignment (fd.o #67279,
1375 • Avoid calling function parameters "interface" since certain Windows headers
1376 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
1378 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
1380 • Various thread-safety improvements to static variables (fd.o #68610,
1383 • Make "make -j check" work (fd.o #68852, Simon McVittie)
1385 • Fix a NULL pointer dereference on an unlikely error path
1386 (fd.o #69327, Sviatoslav Chagaev)
1388 • Improve valgrind memory pool tracking (fd.o #69326,
1391 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
1394 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
1395 (fd.o #66107, Chengwei Yang)
1398 · If accept4() fails with EINVAL, as it can on older Linux kernels
1399 with newer glibc, try accept() instead of going into a busy-loop.
1400 (fd.o #69026, Chengwei Yang)
1401 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
1402 for instance on Hurd or older Linux with a new glibc, try without
1403 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)

1409 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
1410 · Use dbus-launch from the builddir for testing, not the installed copy
1411 (fd.o #37849, Chengwei Yang)
1412 · Fix compilation if writev() is unavailable (fd.o #69409,
1414 · Remove broken support for LOCAL_CREDS credentials passing, and
1415 document where each credential-passing scheme is used (fd.o #60340,

1441 Chengwei Yang, Vasiliy Balyasnyy)
1443 D-Bus 1.7.4 (2013-06-13)
1446 The “but is your thread-safety thread-safe?” release.
1450 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
1451 of service for system services. Vulnerability reported by Alexandru Cornea.
1456 • The Windows version of libdbus now contains a C++ source file, used
1457 to provide global initialization when the library is loaded.
1458 gcc (mingw*) users should ensure that g++ is also installed.
1460 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
1461 and was never the recommended option) has been removed. Expat is now a
1466 • It should now be safe to call dbus_threads_init_default() from any thread,
1467 at any time. Authors of loadable modules and plugins that use libdbus
1468 should consider doing so during initialization.
1469 (fd.o #54972, Simon McVittie)
1471 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
1475 · dbus-run-session: experimental new tool to start a temporary D-Bus
1476 session, e.g. for regression tests or a text console, replacing
1477 certain uses of dbus-launch which weren't really correct
1478 (fd.o #39196, Simon)
1482 • In dbus-daemon, don't crash if a .service file starts with key=value
1483 (fd.o #60853, Chengwei Yang)
1486 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
1487 on a platform not defining LOG_PERROR, such as Solaris or QNX.
1488 This regressed in 1.7.0. (Simon)
1489 · Fix an assertion failure if we try to activate systemd services before
1490 systemd connects to the bus (fd.o #50199, Chengwei Yang)
1491 · Avoid compiler warnings for ignoring the return from write()
1495 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
1496 so that Windows finds them (fd.o #59733, Ralf Habacker)
1498 D-Bus 1.7.2 (2013-04-25)
1501 The “only partially opaque” release.
1503 Configuration changes:
1505 • On non-QNX Unix platforms, the default limit on fds per message in the
1506 session bus configuration has reduced from 4096 to 1024. The default
1507 limit used on the system bus was already 1024. On QNX, both limits are
1508 reduced further, to 128.
1512 • D-Bus Specification 0.21
1513 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
1514 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
1519 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
1520 (i.e. before allocating the slot) rather than returning junk

1527 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
1528 · Under systemd, log to syslog only, not stderr, avoiding duplication
1529 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
1530 · Under systemd, remove unnecessary dependency on syslog.socket
1531 (fd.o #63531, Cristian Rodríguez)

1550 The "Disingenuous Assertions" release.
1552 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
1553 remains the recommended version for long-term-supported distributions
1554 or the upcoming GNOME 3.8 release.
1556 Build-time configuration changes:
1558 • The --with-dbus-session-bus-default-address configure option is no longer
1559 supported. Use the new --with-dbus-session-bus-connect-address and
1560 --with-dbus-session-bus-listen-address options instead. On Windows, you
1561 usually want them to have the same argument; on Unix, the defaults are
1564 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
1565 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
1566 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
1568 • cmake/cross-compile.sh has been removed. Instead, please use a
1569 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
1570 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
1571 as documented in "info automake Cross-Compilation", and set
1572 PKG_CONFIG_PATH appropriately.
1576 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
1577 • man2html is no longer used.
1581 • D-Bus Specification 0.20
1582 · actually say that /org/freedesktop/DBus is the object that
1583 implements o.fd.DBus (fd.o #51865, Colin Walters)
1584 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
1585 · stop claiming that all basic types work just like INT32 (strings don't!)
1587 • The "source code" for the man pages is now Docbook XML, eliminating
1588 the outdated duplicate copies used when building with CMake.
1589 (fd.o #59805; Ralf Habacker, Simon McVittie)
1593 • In the activation helper, when compiled for tests, do not reset the system
1594 bus address, fixing the regression tests. (fd.o #52202, Simon)
1596 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
1597 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
1599 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

1617 · Update sd-daemon.[ch] from systemd (fd.o #60681)
1618 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
1621 · The default session bus listening and connecting address is now
1622 "autolaunch:", which makes D-Bus on Windows interoperate with itself
1623 and GDBus "out of the box". Use the configure options and cmake variables
1624 described above if you require a different autolaunch scope.
1625 (fd.o #38201, Simon McVittie)
1626 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
1628 • Create session.d, system.d directories under CMake (fd.o #41319,
1631 D-Bus 1.6.8 (2012-09-28)
1634 The "Fix one thing, break another" release.
1636 • Follow up to CVE-2012-3524: The additional hardening
1637 work to use __secure_getenv() as a followup to bug #52202
1638 broke certain configurations of gnome-keyring. Given
1639 the difficulty of making this work without extensive
1640 changes to gnome-keyring, use of __secure_getenv() is

1682 (fd.o #51032, Simon McVittie)
1684 • Disconnect "developer mode" (assertions, verbose mode etc.) from
1685 Automake maintainer mode. D-Bus developers should now configure with
1686 --enable-developer. Automake maintainer mode is now on by default;
1687 distributions can disable it with --disable-maintainer-mode.
1688 (fd.o #34671, Simon McVittie)
1690 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
1691 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)

1752 an unused duplicate copy of the nonce-tcp transport in Windows builds
1753 (fd.o #45896, Simon McVittie)
1755 D-Bus 1.5.12 (2012-03-27)
1758 The “Big Book of Science” release.
1760 • Add public API to validate various string types:
1761 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
1762 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
1763 (fd.o #39549, Simon McVittie)
1765 • Turn DBusBasicValue into public API so bindings don't need to invent their
1766 own "union of everything" type (fd.o #11191, Simon McVittie)
1768 • Enumerate data files included in the build rather than using find(1)
1769 (fd.o #33840, Simon McVittie)
1771 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
1772 in dbus-daemon (fd.o #46273, Alban Crequy)
1775 · make dbus-daemon.exe --print-address (and --print-pid) work again
1776 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
1777 · fix duplicate case value when compiling against mingw-w64
1778 (fd.o #47321, Andoni Morales Alastruey)
1780 D-Bus 1.5.10 (2012-02-21)
1783 The "fire in Delerium" release.
1785 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
1786 and SUSv2) is now required.
1788 • D-Bus Specification 0.19:
1789 · Formally define unique connection names and well-known bus names,
1790 and document best practices for interface, bus, member and error names,
1791 and object paths (fd.o #37095, Simon McVittie)
1792 · Document the search path for session and system services on Unix, and
1793 where they should be installed by build systems (fd.o #21620, fd.o #35306;
1795 · Document the systemd transport (fd.o #35232, Lennart Poettering)
1797 • Make dbus_threads_init() use the same built-in threading implementation
1798 as dbus_threads_init_default(); the user-specified primitives that it
1799 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
1801 • Allow all configured auth mechanisms, not just one (fd.o #45106,
1804 • Improve cmake build system (Ralf Habacker):
1805 · simplify XML parser dependencies (fd.o #41027)
1806 · generate build timestamp (fd.o #41029)
1807 · only create batch files on Windows
1808 · fix option and cache syntax
1809 · add help-options target
1810 · share dbus-arch-deps.h.in with autotools rather than having our
1811 own version (fd.o #41033)
1813 • Build tests successfully with older GLib, as found in e.g. Debian 6
1814 (fd.o #41219, Simon McVittie)
1816 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
1818 • Build documentation correctly if man2html doesn't support filenames on
1819 its command-line (fd.o #43875, Jack Nagel)
1821 • Improve test coverage. To get even more coverage, run the tests with
1822 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
1824 • Reduce the size of the shared library by moving functionality only used
1825 by dbus-daemon, tests etc. into their internal library and deleting
1826 unused code (fd.o #34976, #39759; Simon McVittie)
1828 • Add dbus-daemon --nopidfile option, overriding the configuration, for
1829 setups where the default configuration must include <pidfile/> to avoid
1830 breaking traditional init, but the pid file is in fact unnecessary; use
1831 it under systemd to improve startup time a bit (fd.o #45520,
1834 • Optionally (if configured --with-valgrind) add instrumentation to debug
1835 libdbus and associated tools more meaningfully under Valgrind
1836 (fd.o #37286, Simon McVittie)
1838 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
1840 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
1842 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
1843 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
1844 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
1847 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
1851 · Replace our broken reimplementation of recursive mutexes, which has
1852 been broken since 2006, with an ordinary pthreads recursive mutex
1853 (fd.o #43744; Sigmund Augdal, Simon McVittie)
1854 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
1855 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
1856 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
1857 · When running under systemd, use it instead of ConsoleKit to check
1858 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
1859 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
1860 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
1861 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
1862 (fd.o #41218, Simon McVittie)
1863 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
1864 helper doesn't obey environment variables to avoid privilege escalation
1865 attacks, so make the system bus follow the same rules
1866 (fd.o #21620, Simon McVittie)
1869 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
1870 Jesper Dam, Ralf Habacker)
1871 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
1874 D-Bus 1.5.8 (2011-09-21)
1877 The "cross-metering" release.
1879 In addition to dead code removal and refactoring, this release contains all
1880 of the bugfixes from 1.4.16.
1882 • Clean up dead code, and make more warnings fatal in development builds
1883 (fd.o #39231, fd.o #41012; Simon McVittie)
1885 • If full test coverage is requested via --enable-tests, strictly require
1886 Python, pygobject and dbus-python, which are required by some tests; if not,
1887 and Python is missing, skip those tests rather than failing
1888 (fd.o #37847, Simon McVittie)
1890 • When using cmake, provide the same version-info API in the installed headers
1891 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
1893 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
1895 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
1897 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
1900 • Fix duplicates in authors list (Ralf Habacker)
1902 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
1903 (fd.o #39879, Chris Mayo)
1905 • Fix a small memory leak, and a failure to report errors, when updating
1906 a service file entry for activation (fd.o #39230, Simon McVittie)
1909 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
1910 Brian Cameron, Simon McVittie)
1911 · On systems that use libcap-ng but not systemd, drop supplemental groups
1912 when switching to the daemon user (Red Hat #726953, Steve Grubb)
1913 · Make the cmake build work again on GNU platforms (fd.o #29228,
1915 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
1916 like Solaris (fd.o #40313, Dagobert Michelsen)
1917 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
1918 (fd.o #40235, Simon McVittie)
1919 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
1920 (fd.o #39987, Simon McVittie)
1921 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
1922 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
1925 · Fix compilation on MSVC, which doesn't understand "inline" with its
1926 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
1927 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
1928 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
1930 D-Bus 1.5.6 (2011-07-29)
1933 The "weird, gravy-like aftertaste" release.
1935 In addition to new features and refactoring, this release contains all of the
1936 bugfixes from 1.4.14.
1938 Potentially incompatible (Bustle and similar debugging tools will need
1939 changes to work as intended):
1941 • Do not allow match rules to "eavesdrop" (receive messages intended for a
1942 different recipient) by mistake: eavesdroppers must now opt-in to this
1943 behaviour by putting "eavesdrop='true'" in the match rule, which will
1944 not have any practical effect on buses where eavesdropping is not allowed
1945 (fd.o #37890, Cosimo Alfarano)
1949 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
1950 Cosimo Alfarano, Simon McVittie)
1951 · add the "eavesdrop" keyword to match rules
1952 · define eavesdropping, unicast messages and broadcast messages
1953 · stop claiming that match rules are needed to match unicast messages to you
1954 · promote the type system to be a top-level section
1956 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
1957 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
1958 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
1960 • Consistently use atomic operations on everything that is ever manipulated
1961 via atomic ops, as was done for changes to DBusConnection's refcount in
1962 1.4.12 (fd.o #38005, Simon McVittie)
1964 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
1967 • Make "make check" in a clean tree work, by not running tests until
1968 test data has been set up (fd.o #34405, Simon McVittie)
1970 • The dbus-daemon no longer busy-loops if it has a very large number of file
1971 descriptors (fd.o #23194, Simon McVittie)
1973 • Refactor message flow through dispatching to avoid locking violations if
1974 the bus daemon's message limit is hit; remove the per-connection link cache,
1975 which was meant to improve performance, but now reduces it (fd.o #34393,
1978 • Some cmake fixes (Ralf Habacker)
1980 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
1981 Simon McVittie, Lennart Poettering)
1983 • Stop storing two extra byte order indicators in each D-Bus message
1984 (fd.o #38287, Simon McVittie)
1986 • Add an optional Stats interface which can be used to get statistics from
1987 a running dbus-daemon if enabled at configure time with --enable-stats
1988 (fd.o #34040, Simon McVittie)
1990 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
1992 • Documentation (fd.o #36156, Simon McVittie):
1993 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
1994 · install more documentation automatically, including man2html output
1995 · put dbus.devhelp in the right place (it must go in ${htmldir})
1998 · look for system services in /lib/dbus-1/system-services in addition to all
1999 the other well-known locations; note that this should always be /lib,
2000 even on platforms where shared libraries on the root FS would go in /lib64,
2001 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2002 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2004 • Windows-specific (Ralf Habacker):
2005 · fix use of a mutex for autolaunch server detection
2006 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2008 D-Bus 1.5.4 (2011-06-10)
2011 Security (local denial of service):
2013 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2014 local DoS if foreign-endian messages are relayed through the dbus-daemon
2015 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2016 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2020 • The constant to use for an infinite timeout now has a name,
2021 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2022 which can be used for source compatibility with older versions of libdbus.
2024 • If GLib and DBus-GLib are already installed, more tests will be built,
2025 providing better coverage. The new tests can also be installed via
2026 ./configure --enable-installed-tests
2027 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2031 • Consistently use atomic operations for the DBusConnection's refcount,
2032 fixing potential threading problems (fd.o #38005, Simon McVittie)
2034 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2035 small (300KiB on x86-64) and it frequently doesn't work in unusual
2036 toolchains. To optimize for minimum installed size, you should benchmark
2037 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2038 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2040 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2041 (fd.o #35880, Timothy Redaelli)
2043 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2044 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2046 • Windows-specific changes:
2047 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2049 D-Bus 1.5.2 (2011-06-01)
2052 The "Boar Hunter" release.
2054 Notes for distributors:
2056 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2057 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2058 toolchain supports it reliably, via something like:
2060 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2062 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2066 • D-Bus Specification v0.17
2067 · Reserve the extra characters used in signatures by GVariant
2068 (fd.o #34529, Simon McVittie)
2069 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2070 • Don't force -fPIE: distributions and libtool know better than we do whether
2071 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2072 • Allow --disable-gc-sections, in case your toolchain offers the
2073 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2074 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2075 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2076 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2077 • Ensure that maintainers upload documentation with the right permissions
2078 (fd.o #36130, Simon McVittie)
2079 • Don't force users of libdbus to be linked against -lpthread, -lrt
2080 (fd.o #32827, Simon McVittie)
2081 • Log system-bus activation information to syslog (fd.o #35705,
2083 • Log messages dropped due to quotas to syslog (fd.o #35358,
2085 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
2086 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
2087 (fd.o #35228, Lennart Poettering)
2088 • In the regression tests, don't report fds as "leaked" if they were open
2089 on startup (fd.o #35173, Simon McVittie)
2090 • Make dbus-monitor bail out if asked to monitor more than one bus,
2091 rather than silently using the last one (fd.o #26548, Will Thompson)
2092 • Clarify documentation (fd.o #35182, Simon McVittie)
2093 • Clean up minor dead code and some incorrect error handling
2094 (fd.o #33128, fd.o #29881; Simon McVittie)
2095 • Check that compiler options are supported before using them (fd.o #19681,
2098 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
2100 D-Bus 1.5.0 (2011-04-11)
2103 The "you never know when you need to tow something from your giant
2104 flying shark" release.
2106 • D-Bus Specification v0.16
2107 · Add support for path_namespace and arg0namespace in match rules
2108 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
2109 · Make argNpath support object paths, not just object-path-like strings,
2110 and document it better (fd.o #31818, Will Thompson)
2111 • Let the bus daemon implement more than one interface (fd.o #33757,
2113 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2115 • Require user intervention to compile with missing 64-bit support
2116 (fd.o #35114, Simon McVittie)
2117 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
2118 • Raise UnknownObject instead of UnknownMethod for calls to methods on
2119 paths that are not part of the object tree, and UnknownInterface for calls
2120 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
2122 D-Bus 1.4.8 (2011-04-08)
2125 The "It's like the beginning of a lobster" release.
2127 • Rename configure.in to configure.ac, and update it to modern conventions
2128 (fd.o #32245; Javier Jardón, Simon McVittie)
2129 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
2131 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
2132 --disable-x11-autolaunch configure option to prevent it altogether
2133 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
2134 • Install the documentation, and an index for Devhelp (fd.o #13495,
2135 Debian #454142; Simon McVittie, Matthias Clasen)
2136 • If checks are not disabled, check validity of string-like types and
2137 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
2138 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
2139 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
2140 • Break up a huge conditional in config-parser so gcov can produce coverage
2141 data (fd.o #10887, Simon McVittie)
2142 • List which parts of the Desktop Entry specification are applicable to
2143 .service files (fd.o #19159, Sven Herzberg)
2144 • Don't suppress service activation if two services have the same Exec=
2145 (fd.o #35750, Colin Walters)

2155 The "1, 2, miss a few, 99, 100" release.
2157 • Remove unfinished changes intended to support GTest-based tests,
2158 which were mistakenly included in 1.4.4
2160 D-Bus 1.4.4 (2010-02-17)
2163 • Switch back to using even micro versions for stable releases; 1.4.1
2164 should have been called 1.4.2, so skip that version number
2165 • Don't leave bad file descriptors being watched when spawning processes,
2166 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
2167 also LP#656134, LP#680444, LP#713157)
2168 • Check for MSG_NOSIGNAL correctly
2169 • Fix failure to detect abstract socket support (fd.o #29895)
2170 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
2171 (fd.o #32262, NB#180486)
2172 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,

2201 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
2202 crash the bus. The existing restriction to 64-levels of nesting previously
2203 only applied to the static type signature; now it also applies to dynamic
2204 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
2206 • OS X portability fixes, including launchd support.
2207 • Windows autolaunch improvements.
2208 • Various bug fixes.
