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)
19 • Avoid a -Werror=declaration-after-statement build failure on Solaris
20 (fd.o #102145, Alan Coopersmith)
22 D-Bus 1.10.22 (2017-07-27)
25 The “roof terrace” release.
29 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
30 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
32 • dbus_message_iter_open_container() no longer leaks memory if it runs out
33 of memory. (fd.o #101568, Simon McVittie)
35 • dbus_message_append_args_valist() no longer leaks memory if given an
36 unsupported type. This situation is still considered to be a programming
37 error which needs to be corrected by the user of libdbus.
38 (fd.o #101568, Simon McVittie)
40 • Wrap test-pending-call-disconnected with dbus-run-session so that it can
41 pass in environments that are not already running a D-Bus session bus,
42 fixing a build-time test regression in 1.10.20
43 (fd.o #101698, Simon McVittie)
45 • Ensure that tests fail if they would otherwise have tried to connect to
46 the real session bus (fd.o #101698, Simon McVittie)
48 • Make build-time tests cope with finding Python 3, but not Python 2
49 (fd.o #101716, Simon McVittie)
51 D-Bus 1.10.20 (2017-06-29)
54 The “suggesting a delivery gone horribly wrong” release.
58 • Fix a reference leak when blocking on a pending call on a connection
59 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
61 • Don't put timestamps in the Doxygen-generated documentation, for
62 closer-to-reproducible builds (fd.o #100692, Simon McVittie)
64 • Avoid an assertion failure when connecting to a semicolon-separated
65 series of addresses, one of which fails (fd.o #101257, Simon McVittie)
69 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
70 (fd.o #100715, Simon McVittie)
72 D-Bus 1.10.18 (2017-04-05)
75 The “can't handle a self-referential paradox” release.
79 • Re-order dbus-daemon startup so that on SELinux systems, the thread
80 that reads AVC notifications retains the ability to write to the
81 audit log (fd.o #92832, Debian #857660; Laurent Bigonville)
83 • Fix a harmless read overflow and some memory leaks in a unit test
84 (fd.o #100568, Philip Withnall)
86 D-Bus 1.10.16 (2017-02-16)
89 The “super digging powers” release.
91 The fixes in this release are arguably security fixes, but if they
92 affect you, please take this opportunity to rethink how you are
97 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
98 stable and Debian testing in addition to the older Ubuntu that is
99 the default (fd.o #98889, Simon McVittie)
103 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
104 allow an attacker to overwrite a file named "nonce", in a directory
105 that the user running dbus-daemon can write, with a random value
106 known only to the user running dbus-daemon. This is unlikely to be
107 exploitable in practice, particularly since the nonce-tcp transport
108 is really only useful on Windows.
110 On Unix systems we strongly recommend using only the unix: and systemd:
111 transports, together with EXTERNAL authentication. These are the only
112 transports and authentication mechanisms enabled by default.
114 (fd.o #99828, Simon McVittie)
116 • Avoid symlink attacks in the "embedded tests", which are not enabled
117 by default and should never be enabled in production builds of dbus.
118 (fd.o #99828, Simon McVittie)
120 D-Bus 1.10.14 (2016-11-28)
123 The “Well, other bands know more than three chords” release.
127 • Work around an undesired effect of the fix for CVE-2014-3637
128 (fd.o #80559), in which processes that frequently send fds, such as
129 logind during a flood of new PAM sessions, can get disconnected for
130 continuously having at least one fd "in flight" for too long;
131 dbus-daemon interprets that as a potential denial of service attack.
132 The workaround is to disable that check for uid 0 process such as
133 logind, with a message in the system log. The bug remains open while
134 we look for a more general solution.
135 (fd.o #95263, LP#1591411; Simon McVittie)
137 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
138 was disabled at compile time. That test is not expected to work
139 in that configuration. (fd.o #98665, Simon McVittie)
141 D-Bus 1.10.12 (2016-10-10)
144 The “not excessively inhospitable” release.
148 • Do not treat ActivationFailure message received from root-owned systemd
149 name as a format string. In principle this is a security vulnerability,
150 but we do not believe it is exploitable in practice, because only
151 privileged processes can own the org.freedesktop.systemd1 bus name, and
152 systemd does not appear to send activation failures that contain "%".
154 Please note that this probably *was* exploitable in dbus versions
155 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
156 the time was only thought to be a denial of service vulnerability
157 (CVE-2015-0245). If you are still running one of those versions,
158 patch or upgrade immediately.
160 (fd.o #98157, Simon McVittie)
164 • Harden dbus-daemon against malicious or incorrect ActivationFailure
165 messages by rejecting them if they do not come from a privileged
166 process, or if systemd activation is not enabled
167 (fd.o #98157, Simon McVittie)
169 • Avoid undefined behaviour when setting reply serial number without going
170 via union DBusBasicValue (fd.o #98035, Marc Mutz)
172 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
174 D-Bus 1.10.10 (2016-08-15)
177 The “tungsten door” release.
181 • On Linux, when dbus-daemon is run with reduced susceptibility to the
182 OOM killer (typically via systemd), do not let child processes inherit
183 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
185 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
186 contains a semicolon (fd.o #94746, Thiago Macieira)
188 • Fix memory leaks and thread safety in subprocess starting on Windows
189 (fd.o #95191, Ralf Habacker)
191 • Do not require systemd to have a service file if using it for activation
192 (fd.o #93194; Simon McVittie; backport from 1.11.0)
194 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
195 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
197 • In tests that exercise correct handling of crashing D-Bus services,
198 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
200 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
202 • update-activation-environment: produce better diagnostics on error
203 (fd.o #96653, Simon McVittie)
205 • Don't fail the build with an unused const variable warning under gcc 6
206 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
208 • Merge dbus-1.10-ci branch, containing backports from 1.11.0 in build/test
209 code to support continuous integration (fd.o #93194, Simon McVittie)
211 · Avoid -Wunused-label when compiling with libselinux but no libaudit
212 · In development builds, allow OOM tests to be disabled as documented
213 · Accept and ignore the --tap argument in all "embedded tests", and run
214 all automated tests with that argument for better diagnostics
215 · Fix the systemd activation test under CMake by installing the required
217 · In Automake, fix shell syntax for installcheck-local with no DESTDIR
218 · In Automake, don't try to run manual tests in installcheck
219 · In CMake, don't run manual-tcp test as an automated test
220 · Add travis-ci.org build machinery
222 D-Bus 1.10.8 (2016-03-07)
225 The “digestive biscuits” release.
229 • Enable "large file support" on systems where it exists: dbus-daemon
230 is not expected to open large files, but it might need to stat files
231 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
233 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
234 which might result in a pedantic C compiler not copying the entire contents
235 of a DBusMessageIter; statically assert that this is not an ABI change
236 in practice (fd.o #94136, Simon McVittie)
238 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
239 (fd.o #94244, Dmitri Iouchtchenko)
241 • Correctly report test failures in C tests from run-test.sh
242 (fd.o #93379; amit tewari, Simon McVittie)
244 • When tests are enabled, run all the marshal-validate tests, not just
245 the even-numbered ones (fd.o #93908, Nick Lewycky)
247 • Correct the expected error from one marshal-validate test, which was
248 previously not run due to the above bug (fd.o #93908, Simon McVittie)
250 D-Bus 1.10.6 (2015-12-01)
253 The “marzipan beetles” release.
257 • On Unix when running tests as root, don't assert that root and
258 the dbus-daemon user can still call UpdateActivationEnvironment;
259 assert that those privileged users can call BecomeMonitor instead
260 (fd.o #93036, Simon McVittie)
262 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
265 • On Windows Autotools builds, don't run tests that rely on
266 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
268 D-Bus 1.10.4 (2015-11-17)
271 The “Frostburn Canyon” release.
275 • GetConnectionCredentials, GetConnectionUnixUser and
276 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
277 will now return details of the dbus-daemon itself. This is required
278 to be able to call SetEnvironment on systemd.
279 (fd.o #92857, Jan Alexander Steffens)
283 • Make UpdateActivationEnvironment always fail with AccessDenied on the
284 system bus. Previously, it was possible to configure it so root could
285 call it, but the environment variables were not actually used,
286 because the launch helper would discard them.
287 (fd.o #92857, Jan Alexander Steffens)
289 • On Unix with --systemd-activation on a user bus, make
290 UpdateActivationEnvironment pass on its arguments to systemd's
291 SetEnvironment method, solving inconsistency between the environments
292 used for traditional activation and systemd user-service activation.
293 (fd.o #92857, Jan Alexander Steffens)
295 • On Windows, don't crash if <syslog/> or --syslog is used
296 (fd.o #92538, Ralf Habacker)
298 • On Windows, fix a memory leak when setting a DBusError from a Windows
299 error (fd.o #92721, Ralf Habacker)
301 • On Windows, don't go into infinite recursion if we abort the process
302 with backtraces enabled (fd.o #92721, Ralf Habacker)
304 • Fix various failing tests, variously on Windows and cross-platform:
305 · don't test system.conf features (users, groups) that only make sense
306 on the system bus, which is not supported on Windows
307 · don't call _dbus_warn() when we skip a test, since it is fatal
308 · fix computation of expected <standard_session_servicedirs/>
309 · when running TAP tests, translate newlines to Unix format, fixing
310 cross-compiled tests under Wine on Linux
311 · don't stress-test refcounting under Wine, where it's really slow
312 · stop assuming that a message looped-back to the test will be received
314 · skip some system bus tests on Windows since they make no sense there
315 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
317 D-Bus 1.10.2 (2015-10-26)
320 The “worst pies in London” release.
324 • Correct error handling for activation: if there are multiple attempts
325 to activate the same service and it fails immediately, the first attempt
326 would get the correct reply, but the rest would time out. We now send
327 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
329 • If BecomeMonitor is called with a syntactically invalid match rule,
330 don't crash with an assertion failure, fixing a regression in 1.9.10.
331 This was not exploitable as a denial of service, because the check
332 for a privileged user is done first. (fd.o #92298, Simon McVittie)
334 • On Linux with --enable-user-session, add the bus address to the
335 environment of systemd services for better backwards compatibility
336 (fd.o #92612, Jan Alexander Steffens)
338 • On Windows, fix the logic for replacing the installation prefix
339 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
341 • On Windows, if installed in the conventional layout with ${prefix}/etc
342 and ${prefix}/share, use relative paths between bus configuration files
343 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
345 • Make more of the regression tests pass in Windows builds (fd.o #92538,
348 D-Bus 1.10.0 (2015-08-25)
353 This is a new stable branch, recommended for use in OS distributions.
357 • distribute test/tap-test.sh.in, even if the tarball was built without
358 tests enabled (fd.o #91684, Simon McVittie)
359 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
361 Summary of major changes since 1.8.0:
363 • The basic setup for the well-known system and session buses is
364 now done in read-only files in ${datadir} (normally /usr/share).
365 See the NEWS entry for 1.9.18 for details.
367 • AppArmor integration has been merged, with features similar to the
368 pre-existing SELinux integration. It is mostly compatible with the
369 patches previously shipped by Ubuntu, with one significant change:
370 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
371 by GetConnectionCredentials and was not included.
373 • The --enable-user-session configure option can be enabled
374 by OS integrators intending to use systemd to provide a session bus
375 per user (in effect, treating all concurrent graphical and non-graphical
376 login sessions as one large session).
378 • The new listenable address mode "unix:runtime=yes" listens on
379 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
380 user session. libdbus and "dbus-launch --autolaunch" will connect to
381 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
384 • All executables are now dynamically linked to libdbus-1.
385 Previously, some executables, most notably dbus-daemon, were statically
386 linked to a specially-compiled variant of libdbus. This results in
387 various private functions in the _dbus namespace being exposed by the
388 shared library. These are not API, and must not be used outside
389 the dbus source tree.
391 • On platforms with ELF symbol versioning, all public symbols
392 are versioned LIBDBUS_1_3.
396 • org.freedesktop.DBus.GetConnectionCredentials returns
397 LinuxSecurityLabel where supported
398 • org.freedesktop.DBus.Monitoring interface (privileged)
399 · BecomeMonitor method supersedes match rules with eavesdrop=true,
400 which are now deprecated
401 • org.freedesktop.DBus.Stats interface (semi-privileged)
402 · now enabled by default
403 · new GetAllMatchRules method
404 • org.freedesktop.DBus.Verbose interface (not normally compiled)
405 · toggles the effect of DBUS_VERBOSE
410 • dbus-update-activation-environment
412 New optional dependencies:
414 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
415 • Complete documentation requires Ducktype and yelp-tools
416 • Full test coverage requires GLib 2.36 and PyGI
417 • AppArmor integration requires libapparmor and optionally libaudit
419 Dependencies removed:
423 D-Bus 1.9.20 (2015-08-06)
426 The “Remember Tomorrow” release.
428 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
433 • Don't second-guess what the ABI of poll() is, allowing it to be used
434 on Integrity RTOS and other unusual platforms (fd.o #90314;
435 Rolland Dudemaine, Simon McVittie)
437 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
438 both enabled (fd.o #89225, Simon McVittie)
440 • Log audit events for AppArmor/SELinux policy violations whenever
441 we have CAP_AUDIT_WRITE, even if not the system bus
442 (fd.o #83856, Laurent Bigonville)
444 D-Bus 1.9.18 (2015-07-21)
447 The “Pirate Elite” release.
449 Configuration changes:
451 • The basic setup for the well-known system and session buses is now done
452 in read-only files in ${datadir}, moving a step closer to systems
453 that can operate with an empty /etc directory. In increasing order
456 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
457 the default message policies.
458 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
459 dbus still installs a trivial version of each, for documentation
460 purposes; putting configuration directives in these files is deprecated.
461 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
462 to install "drop-in" configuration snippets (any packages
463 using those directories should explicitly depend on at least this
465 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
466 or third-party software to install "drop-in" configuration snippets
467 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
470 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
471 and "s*" refers to either system or session as appropriate.
473 (fd.o #89280, Dimitri John Ledkov)
477 • Fix a memory leak when GetConnectionCredentials() succeeds
478 (fd.o #91008, Jacek Bukarewicz)
480 • Ensure that dbus-monitor does not reply to messages intended for others,
481 resulting in its own disconnection (fd.o #90952, Simon McVittie)
483 D-Bus 1.9.16 (2015-05-14)
486 The “titanium barns” release.
490 • Automake 1.13 is now required when compiling from git or modifying
495 • On Unix platforms, change the default configuration for the session bus
496 to only allow EXTERNAL authentication (secure kernel-mediated
497 credentials-passing), as was already done for the system bus.
499 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
500 unpredictable pseudo-random numbers.
502 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
503 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
504 NFS or similar, you will need to reconfigure the session bus to accept
505 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
508 (fd.o #90414, Simon McVittie)
510 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
511 transport, UUIDs or any other reason, fail if we cannot obtain entropy
512 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
513 occurs, instead of silently falling back to low-entropy pseudorandom
514 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
518 • Add dbus_message_iter_get_element_count()
519 (fd.o #30350; Christian Dywan, Simon McVittie)
521 • Introduce new internal DBusSocket and DBusPollable types so we can
522 stop treating the Windows SOCKET type as if it was int. DBusSocket
523 is specifically a socket, cross-platform. DBusPollable is whatever
524 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
525 (fd.o #89444; Ralf Habacker, Simon McVittie)
527 • All regression tests now output TAP <https://testanything.org/>
528 (fd.o #89846, Simon McVittie)
530 • Internal APIs consistently use signed values for timestamps
531 (fd.o #18494, Peter McCurdy)
533 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
534 (fd.o #88812, Simon McVittie)
536 • Clean up a lot of compiler warnings
537 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
541 • Add locking to DBusCounter's reference count and notify function
542 (fd.o #89297, Adrian Szyndela)
544 • Ensure that DBusTransport's reference count is protected by the
545 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
547 • Correctly release DBusServer mutex before early-return if we run out
548 of memory while copying authentication mechanisms (fd.o #90021,
551 • Make dbus-test-tool and dbus-update-activation-environment portable
552 to Windows (fd.o #90089, Ralf Habacker)
554 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
555 Ralf Habacker, Simon McVittie)
557 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
560 • Clean up some memory and fd leaks in test code and tools
561 (fd.o #90021, Ralf Habacker)
563 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
564 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
566 • CMake generates a versioned shared library even if the revision is 0,
567 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
569 D-Bus 1.9.14 (2015-03-02)
572 The “don't stand in the poison cloud” release.
576 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
577 were previously linked to a static version of libdbus.
579 • The tests no longer require dbus-glib in order to exercise the libdbus
580 shared library; they are always linked to libdbus now.
582 Build-time configuration:
584 • The new --enable-user-session option, off by default, can be enabled
585 by OS integrators intending to use systemd to provide a session bus
586 per user (in effect, treating all concurrent graphical and non-graphical
587 login sessions as one large session)
591 • All executables are now linked dynamically to libdbus.
592 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
594 • On platforms that support them (GNU libc and possibly others),
595 libdbus now has versioned symbols for its public API.
596 All public symbols (visible in the header files) are currently
597 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
598 dbus_internal have a version that changes with each release, and
599 must not be used by applications. (also fd.o #83115)
601 • New listenable address mode "unix:runtime=yes" which listens on
602 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
603 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
605 • Add optional systemd units for a per-user bus listening on
606 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
608 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
609 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
612 • New dbus-update-activation-environment tool uploads environment
613 variables to "dbus-daemon --session" and optionally "systemd --user",
614 primarily as a way to keep the per-user bus compatible with
615 distributions' existing X11 login scripts (also fd.o #61301)
617 • <includedir/> elements in dbus-daemon configuration are now silently
618 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
620 • Add microsecond-resolution timestamps to the default output of
621 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
625 • Fix a race condition in the 'monitor' test introduced in 1.9.10
626 (fd.o #89222, Simon McVittie)
628 D-Bus 1.9.12 (2015-02-19)
631 The “monster lasagna” release.
635 • Ducktype and yelp-tools are now required to build complete documentation
636 (they are optional for normal builds).
640 • D-Bus Specification version 0.26
641 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
642 · document the BecomeMonitor method
644 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
645 (fd.o #89041; Tyler Hicks, Simon McVittie)
647 • On Linux, add support for AppArmor mediation of message sending and
648 receiving and name ownership (paralleling existing SELinux mediation
649 support), and eavesdropping (a new check, currently AppArmor-specific)
650 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
652 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
653 that have printable ASCII contents; we previously only did this for
654 unterminated bytestrings (fd.o #89109, Simon McVittie)
656 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
658 • On Windows, add WindowsSID to GetConnectionCredentials
659 (fd.o #54445, Ralf Habacker)
661 • Improve clarity of dbus-monitor --profile output and add more columns
662 (fd.o #89165, Ralf Habacker)
664 • Add a man page for dbus-test-tool, and build it under CMake as well
665 as Autotools (fd.o#89086, Simon McVittie)
667 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
668 to control it at runtime, overriding the DBUS_VERBOSE environment variable
669 (fd.o #88896, Ralf Habacker)
673 • Reduce the number of file descriptors used in the fd-passing test,
674 avoiding failure under the default Linux fd limit, and automatically
675 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
677 D-Bus 1.9.10 (2015-02-09)
680 The “sad cyborgs” release.
682 Security fixes merged from 1.8.16:
684 • Do not allow non-uid-0 processes to send forged ActivationFailure
685 messages. On Linux systems with systemd activation, this would
686 allow a local denial of service: unprivileged processes could
687 flood the bus with these forged messages, winning the race with
688 the actual service activation and causing an error reply
689 to be sent back when service auto-activation was requested.
690 This does not prevent the real service from being started,
691 so the attack only works while the real service is not running.
692 (CVE-2015-0245, fd.o #88811; Simon McVittie)
696 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
697 similar tools receive messages without altering the security properties
698 of the system bus, by calling the new BecomeMonitor method on a
699 private connection. This bypasses the normal <allow> and <deny> rules
700 entirely, so to preserve normal message-privacy assumptions, only root
701 is allowed to do this on the system bus. Restricted environments,
702 such as Linux with LSMs, should lock down access to the Monitoring
703 interface. (fd.o #46787, Simon McVittie)
705 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
706 dbus-daemon supports it and access permissions allow it.
707 It still supports the previous approach ("eavesdropping" match rules)
708 for compatibility with older bus daemons. (fd.o #46787, Simon)
710 • dbus-monitor can now log the message stream as binary data for later
711 analysis, with either no extra framing beyond the normal D-Bus headers,
712 or libpcap-compatible framing treating each D-Bus message
713 as a captured packet. (fd.o #46787, Simon)
717 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
719 • On Unix, forcibly terminate regression tests after 60 seconds to
720 prevent them from blocking continuous integration frameworks
723 D-Bus 1.9.8 (2015-02-03)
726 The “all the types of precipitation” release.
730 • full test coverage now requires GLib 2.36
731 • full test coverage now requires PyGI (PyGObject 3,
732 "import gi.repository.GObject") instead of the
733 obsolete PyGObject 2 ("import gobject")
737 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
739 • better regression test coverage, including systemd activation
740 (fd.o #57952, #88810; Simon McVittie)
744 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
745 turned off (fd.o #88808, Simon McVittie)
747 • TCP sockets on Windows no longer fail to listen approximately 1 time
748 in 256, caused by a logic error that should have always made it fail but
749 was mitigated by incorrect endianness for the port number
750 (fd.o #87999, Ralf Habacker)
752 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
754 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
755 previous 64, completing a previous fix which only worked under
756 Autotools (fd.o #71297, Ralf Habacker)
758 • on Windows, if the IP family is unspecified only use IPv4,
759 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
761 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
763 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
765 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
768 D-Bus 1.9.6 (2015-01-05)
771 The “I do have a bread knife” release.
775 • Do not allow calls to UpdateActivationEnvironment from uids other than
776 the uid of the dbus-daemon. If a system service installs unsafe
777 security policy rules that allow arbitrary method calls
778 (such as CVE-2014-8148) then this prevents memory consumption and
779 possible privilege escalation via UpdateActivationEnvironment.
781 We believe that in practice, privilege escalation here is avoided
782 by dbus-daemon-launch-helper sanitizing its environment; but
783 it seems better to be safe.
785 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
786 on object paths other than /org/freedesktop/DBus. Some system services
787 install unsafe security policy rules that allow arbitrary method calls
788 to any destination, method and interface with a specified object path;
789 while less bad than allowing arbitrary method calls, these security
790 policies are still harmful, since dbus-daemon normally offers the
791 same API on all object paths and other system services might behave
796 • Add missing initialization so GetExtendedTcpTable doesn't crash on
797 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
799 D-Bus 1.9.4 (2014-11-24)
802 The “extra-sturdy caramel” release.
806 • Partially revert the CVE-2014-3639 patch by increasing the default
807 authentication timeout on the system bus from 5 seconds back to 30
808 seconds, since this has been reported to cause boot regressions for
809 some users, mostly with parallel boot (systemd) on slower hardware.
811 On fast systems where local users are considered particularly hostile,
812 administrators can return to the 5 second timeout (or any other value
813 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
816 <limit name="auth_timeout">5000</limit>
819 (fd.o #86431, Simon McVittie)
821 • Add a message in syslog/the Journal when the auth_timeout is exceeded
822 (fd.o #86431, Simon McVittie)
824 • Send back an AccessDenied error if the addressed recipient is not allowed
825 to receive a message (and in builds with assertions enabled, don't
826 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
828 D-Bus 1.9.2 (2014-11-10)
831 The “structurally unsound flapjack” release.
835 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
836 so that CVE-2014-3636 part A cannot exhaust the system bus'
837 file descriptors, completing the incomplete fix in 1.8.8.
838 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
842 • D-Bus Specification version 0.25
843 · new value 'const' for EmitsChangedSignal annotation
844 (fd.o #72958, Lennart Poettering)
845 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
846 (fd.o #83449; Lennart Poettering, Simon McVittie)
847 · annotate table of types with reserved/basic/container, and for
848 basic types, fixed/string-like
849 · clarify arbitrary limits by quoting them in mebibytes
851 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
852 (fd.o #83449, Simon McVittie)
854 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
855 useful for debugging and performance testing:
856 · dbus-test-tool spam: send repeated messages
857 · dbus-test-tool echo: send an empty reply for all method calls
858 · dbus-test-tool black-hole: do not reply to method calls
859 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
861 • Add support for process ID in credentials-passing on NetBSD
862 (fd.o #69702, Patrick Welche)
864 • Add an example script to find potentially undesired match rules
865 (fd.o #84598, Alban Crequy)
867 • Document the central assumption that makes our use of credentials-passing
868 secure (fd.o #83499, Simon McVittie)
870 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
871 and add some links to GDBus and QtDBus documentation (fd.o #25140,
876 • Use a less confusing NoReply message when disconnected with a reply pending
877 (fd.o #76112, Simon McVittie)
879 • Make the .pc file relocatable by letting pkg-config do all variable
880 expansion itself (fd.o #75858, Руслан Ижбулатов)
882 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
883 (fd.o #85563, Patrick Welche)
885 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
887 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
888 do not lose the exec() errno (fd.o #24821, Simon McVittie)
890 • Do not fail the tests if a parent process has leaked non-close-on-exec
891 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
893 • Do not fail the tests on Unix platforms with incomplete
894 credentials-passing support, but do fail if we can't pass credentials
895 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
896 (fd.o #69702, Simon McVittie)
898 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
899 when building with cmake, and expand test coverage there
900 (fd.o #73689; Ralf Habacker, Simon McVittie)
902 D-Bus 1.9.0 (2014-10-01)
905 The “tiered cheeses” release.
909 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
910 requires either the libsystemd or libsd-daemon shared library, dropping the
911 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
913 Build-time configuration changes:
915 • The Stats interface is now enabled by default, and locked-down to
916 root-only on the system bus. Configure with --disable-stats
917 to disable it altogether on memory- or disk-constrained systems,
918 or see ${docdir}/examples/ to open it up to non-root users on the
919 system bus or restrict access on the session bus.
920 (fd.o #80759; Simon McVittie, Alban Crequy)
922 • The CMake build system now builds the same shared library name as Autotools
923 on at least Linux and Windows:
924 - on Linux (and perhaps other Unix platforms), it previously built
925 libdbus-1.so, but now builds libdbus-1.so.3.* with development
926 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
927 - on Windows, it previously built either libdbus-1.dll (release) or
928 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
929 libdbus-1.dll for compatibility with older applications.
930 (fd.o #74117, Ralf Habacker)
934 • D-Bus Specification version 0.24
935 · document how to quote match rules (fd.o #24307, Simon McVittie)
936 · explicitly say that most message types never expect a reply
937 regardles of whether they have NO_REPLY_EXPECTED
938 (fd.o #75749, Simon McVittie)
940 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
941 initial latency (fd.o #75544, Matt Hoosier)
943 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
944 (fd.o #69702, Patrick Welche)
946 • in dbus-monitor, print more information about file descriptors
947 (fd.o #80603, Alban Crequy)
949 • do not install system bus configuration if built for Windows
950 (fd.o #83583; Ralf Habacker, Simon McVittie)
952 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
954 • Add a regression test for file descriptor passing (fd.o #83622,
959 • fix an incorrect error message if a Unix socket path is too long
960 (fd.o #73887, Antoine Jacoutot)
962 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
963 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
965 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
966 in ps(1) (fd.o #69716, Chengwei Yang)
968 • avoid calling poll() with timeout < -1, which is considered invalid
969 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
971 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
972 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
973 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
975 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
977 • Documentation improvements
978 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
980 • in dbus-monitor, do not leak file descriptors that we have monitored
981 (fd.o #80603, Alban Crequy)
983 • Set the close-on-exec flag for the inotify file descriptor, even
984 if built with CMake or older libc (fd.o #73689, Simon McVittie)
986 • Remove some LGPL code from the Windows dbus-daemon
987 (fd.o #57272, Ralf Habacker)
989 D-Bus 1.8.8 (2014-09-16)
992 The "smashy smashy egg man" release.
996 • Do not accept an extra fd in the padding of a cmsg message, which
997 could lead to a 4-byte heap buffer overrun.
998 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1000 • Reduce default for maximum Unix file descriptors passed per message
1001 from 1024 to 16, preventing a uid with the default maximum number of
1002 connections from exhausting the system bus' file descriptors under
1003 Linux's default rlimit. Distributors or system administrators with a
1004 more restrictive fd limit may wish to reduce these limits further.
1006 Additionally, on Linux this prevents a second denial of service
1007 in which the dbus-daemon can be made to exceed the maximum number
1008 of fds per sendmsg() and disconnect the process that would have
1010 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1012 • Disconnect connections that still have a fd pending unmarshalling after
1013 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1014 removing the possibility of creating an abusive connection that cannot be
1015 disconnected by setting up a circular reference to a connection's
1017 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1019 • Reduce default for maximum pending replies per connection from 8192 to 128,
1020 mitigating an algorithmic complexity denial-of-service attack
1021 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1023 • Reduce default for authentication timeout on the system bus from
1024 30 seconds to 5 seconds, avoiding denial of service by using up
1025 all unauthenticated connection slots; and when all unauthenticated
1026 connection slots are used up, make new connection attempts block
1027 instead of disconnecting them.
1028 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1032 • Check for libsystemd from systemd >= 209, falling back to
1033 the older separate libraries if not found (Umut Tezduyar Lindskog,
1036 • On Linux, use prctl() to disable core dumps from a test executable
1037 that deliberately raises SIGSEGV to test dbus-daemon's handling
1038 of that condition (fd.o #83772, Simon McVittie)
1040 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
1043 • Improve documentation for running tests on Windows (fd.o #41252,
1046 D-Bus 1.8.6 (2014-06-02)
1051 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1052 the message. This prevents an attack in which a malicious client can
1053 make dbus-daemon disconnect a system service, which is a local
1055 (fd.o #80163, CVE-2014-3532; Alban Crequy)
1057 • Track remaining Unix file descriptors correctly when more than one
1058 message in quick succession contains fds. This prevents another attack
1059 in which a malicious client can make dbus-daemon disconnect a system
1061 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
1062 Simon McVittie, Alban Crequy)
1066 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
1067 attach to a session, kill the dbus-daemon as intended
1068 (fd.o #74698, Роман Донченко)
1070 D-Bus 1.8.4 (2014-06-10)
1075 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1076 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1077 Additionally, in highly unusual environments the same flaw could lead to
1078 a side channel between processes that should not be able to communicate.
1079 (CVE-2014-3477, fd.o #78979)
1081 D-Bus 1.8.2 (2014-04-30)
1084 The “nobody wants red” release.
1088 • in the CMake build system, add some hints for Linux users cross-compiling
1089 Windows D-Bus binaries to be able to run tests under Wine
1090 (fd.o #41252, Ralf Habacker)
1092 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
1096 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
1097 to /var/lib/dbus/machine-id instead of generating an entirely new ID
1098 (fd.o #77941, Simon McVittie)
1100 • if dbus-launch receives an X error very quickly, do not kill
1101 unrelated processes (fd.o #74698, Роман Донченко)
1103 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
1104 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
1106 • cope with \r\n newlines in regression tests, since on Windows,
1107 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
1109 D-Bus 1.8.0 (2014-01-20)
1112 The “Wolverine distrusts my printer” release.
1114 This starts a new stable branch. The 1.6.x branch is now considered to be
1115 outdated, and will only receive fixes for serious bugs such as security
1116 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1117 are unlikely to get any more releases, but if distributors still need to
1118 support them, please share security patches via upstream.
1120 Summary of changes since 1.6.x:
1122 • libdbus always behaves as if dbus_threads_init_default() had been called
1123 (thread-safety by default)
1124 • new dbus-run-session tool, replacing certain misuses of dbus-launch
1125 • dbus-monitor can talk to outdated versions of dbus-daemon again
1126 • new org.freedesktop.DBus.GetConnectionCredentials method
1127 • GetConnectionUnixProcessID also works correctly on Windows, returning
1128 the Windows process ID
1129 • GetConnectionWindowsSID returns the correct SID on Windows
1130 • expat is required, libxml2 can no longer be used as a substitute
1131 • the userDB cache is required, and cannot be disabled
1132 • a 64-bit integer type (either int, long, long long or _int64) is required
1133 • better systemd-journald integration on Linux
1134 • fixed long-standing fd and array leaks when failing to parse a message
1135 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
1136 when using certain object-path allocation patterns, notably in Avahi
1137 • better defaults for Windows support
1138 • better CMake support
1139 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
1140 • the source language for the man pages is now Docbook XML
1142 Enhancements since 1.7.10:
1144 • Enhance the CMake build system to check for GLib and compile/run
1145 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
1149 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
1152 • fix compilation of systemd journal support on older systemd versions where
1153 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
1155 • fix compilation on older MSVC versions by including stdlib.h
1156 (fd.o #73455, Ralf Habacker)
1158 • Allow <allow_anonymous/> to appear in an included configuration file
1159 (fd.o #73475, Matt Hoosier)
1161 Test behaviour changes since 1.7.10:
1163 • If the tests crash with an assertion failure, they no longer default to
1164 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
1165 environment if you want the old behaviour.
1167 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
1168 can be run with an external dbus-daemon by setting
1169 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
1170 an unusually-configured dbus-daemon are skipped.
1172 D-Bus 1.7.10 (2014-01-06)
1175 The “weighted companion cube” release.
1177 This is a release candidate for D-Bus 1.8.

1203 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
1205 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
1207 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
1208 and DBUS__SEND_MSG are numerically equal to their values in the
1209 reference policy (fd.o #88719, osmond sun)
1211 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
1212 (fd.o #71366, Matt Fischer)
1214 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
1215 winsock2.h (fd.o #71405, Matt Fischer)
1217 • do not return failure from _dbus_read_nonce() with no error set,
1218 preventing a potential crash (fd.o #72298, Chengwei Yang)
1220 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
1221 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
1223 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
1224 which doesn't do anything anyway on at least Linux and FreeBSD
1225 (fd.o #69492, Simon McVittie)
1227 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
1228 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
1229 for credentials more correctly (fd.o #69492, Simon McVittie)
1231 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
1232 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
1235 • refresh cached policy rules for existing connections when bus
1236 configuration changes (fd.o #39463, Chengwei Yang)
1238 D-Bus 1.7.8 (2013-11-01)
1241 The “extreme hills” release.
1245 • If systemd support is enabled, libsystemd-journal is now required.
1249 • When activating a non-systemd service under systemd, annotate its
1250 stdout/stderr with its bus name in the Journal. Known limitation:
1251 because the socket is opened before forking, the process will still be
1252 logged as if it had dbus-daemon's process ID and user ID.
1253 (fd.o #68559, Chengwei Yang)
1255 • Document more configuration elements in dbus-daemon(1)
1256 (fd.o #69125, Chengwei Yang)
1260 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
1261 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
1263 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
1264 disallowed method calls to the audit log, fixing a regression in 1.7.6
1265 (fd.o #49062, Colin Walters)
1267 • path_namespace='/' in match rules incorrectly matched nothing; it
1268 now matches everything. (fd.o #70799, Simon McVittie)
1270 D-Bus 1.7.6 (2013-10-09)
1273 The “CSI Shrewsbury” release.
1275 Build-time configuration changes:
1277 • Directory change notification via dnotify on Linux is no longer
1278 supported; it hadn't compiled successfully since 2010 in any case.
1279 If you don't have inotify (Linux) or kqueue (*BSD), you will need
1280 to send SIGHUP to the dbus-daemon when its configuration changes.
1281 (fd.o #33001, Chengwei Yang)
1283 • Compiling with --disable-userdb-cache is no longer supported;
1284 it didn't work since at least 2008, and would lead to an extremely
1285 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
1288 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
1289 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
1290 with the Autotools build system. (fd.o #66142, Chengwei Yang)
1292 • --with-valgrind=auto enables Valgrind instrumentation if and only if
1293 valgrind headers are available. The default is still --with-valgrind=no.
1294 (fd.o #56925, Simon McVittie)
1298 • Platforms with no 64-bit integer type are no longer supported.
1299 (fd.o #65429, Simon McVittie)
1301 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
1303 • Full test coverage no longer requires dbus-glib, although the tests do not
1304 exercise the shared library (only a static copy) if dbus-glib is missing.
1305 (fd.o #68852, Simon McVittie)
1309 • D-Bus Specification 0.22
1310 · Document GetAdtAuditSessionData() and
1311 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
1312 · Fix example .service file (fd.o #66481, Chengwei Yang)
1313 · Don't claim D-Bus is "low-latency" (lower than what?), just
1314 give factual statements about it supporting async use
1315 (fd.o #65141, Justin Lee)
1316 · Document the contents of .service files, and the fact that
1317 system services' filenames are constrained
1318 (fd.o #66608; Simon McVittie, Chengwei Yang)
1320 • Be thread-safe by default on all platforms, even if
1321 dbus_threads_init_default() has not been called. For compatibility with
1322 older libdbus, library users should continue to call
1323 dbus_threads_init_default(): it is harmless to do so.
1324 (fd.o #54972, Simon McVittie)
1326 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
1328 • New API: dbus_setenv(), a simple wrapper around setenv().
1329 Note that this is not thread-safe. (fd.o #39196, Simon)
1331 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
1332 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
1333 (connect to a given bus, like dbus-monitor --address=ADDRESS).
1334 dbus-send --address still exists for backwards compatibility,
1335 but is no longer documented. (fd.o #48816, Andrey Mazo)
1338 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
1343 • Avoid an infinite busy-loop if a signal interrupts waitpid()
1344 (fd.o #68945, Simon McVittie)
1346 • Clean up memory for parent nodes when objects are unexported
1347 (fd.o #60176, Thomas Fitzsimmons)
1349 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
1350 documented. Previously, it assumed its second parameter was TRUE.
1351 (fd.o #69165, Chengwei Yang)
1353 • Escape addresses containing non-ASCII characters correctly
1354 (fd.o #53499, Chengwei Yang)
1356 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
1358 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
1359 (fd.o #65923, Chengwei Yang)
1361 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
1362 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
1364 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
1365 that was never va_start()ed (fd.o #66300, Chengwei Yang)
1367 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
1369 • fix a regression test on platforms with strict alignment (fd.o #67279,
1372 • Avoid calling function parameters "interface" since certain Windows headers
1373 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
1375 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
1377 • Various thread-safety improvements to static variables (fd.o #68610,
1380 • Make "make -j check" work (fd.o #68852, Simon McVittie)
1382 • Fix a NULL pointer dereference on an unlikely error path
1383 (fd.o #69327, Sviatoslav Chagaev)
1385 • Improve valgrind memory pool tracking (fd.o #69326,
1388 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
1391 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
1392 (fd.o #66107, Chengwei Yang)
1395 · If accept4() fails with EINVAL, as it can on older Linux kernels
1396 with newer glibc, try accept() instead of going into a busy-loop.
1397 (fd.o #69026, Chengwei Yang)
1398 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
1399 for instance on Hurd or older Linux with a new glibc, try without

1406 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
1407 · Use dbus-launch from the builddir for testing, not the installed copy
1408 (fd.o #37849, Chengwei Yang)
1409 · Fix compilation if writev() is unavailable (fd.o #69409,
1411 · Remove broken support for LOCAL_CREDS credentials passing, and
1412 document where each credential-passing scheme is used (fd.o #60340,

1438 Chengwei Yang, Vasiliy Balyasnyy)
1440 D-Bus 1.7.4 (2013-06-13)
1443 The “but is your thread-safety thread-safe?” release.
1447 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
1448 of service for system services. Vulnerability reported by Alexandru Cornea.
1453 • The Windows version of libdbus now contains a C++ source file, used
1454 to provide global initialization when the library is loaded.
1455 gcc (mingw*) users should ensure that g++ is also installed.
1457 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
1458 and was never the recommended option) has been removed. Expat is now a
1463 • It should now be safe to call dbus_threads_init_default() from any thread,
1464 at any time. Authors of loadable modules and plugins that use libdbus
1465 should consider doing so during initialization.
1466 (fd.o #54972, Simon McVittie)
1468 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
1472 · dbus-run-session: experimental new tool to start a temporary D-Bus
1473 session, e.g. for regression tests or a text console, replacing
1474 certain uses of dbus-launch which weren't really correct
1475 (fd.o #39196, Simon)
1479 • In dbus-daemon, don't crash if a .service file starts with key=value
1480 (fd.o #60853, Chengwei Yang)
1483 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
1484 on a platform not defining LOG_PERROR, such as Solaris or QNX.
1485 This regressed in 1.7.0. (Simon)
1486 · Fix an assertion failure if we try to activate systemd services before
1487 systemd connects to the bus (fd.o #50199, Chengwei Yang)
1488 · Avoid compiler warnings for ignoring the return from write()
1492 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
1493 so that Windows finds them (fd.o #59733, Ralf Habacker)
1495 D-Bus 1.7.2 (2013-04-25)
1498 The “only partially opaque” release.
1500 Configuration changes:
1502 • On non-QNX Unix platforms, the default limit on fds per message in the
1503 session bus configuration has reduced from 4096 to 1024. The default
1504 limit used on the system bus was already 1024. On QNX, both limits are
1505 reduced further, to 128.
1509 • D-Bus Specification 0.21
1510 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
1511 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
1516 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
1517 (i.e. before allocating the slot) rather than returning junk

1524 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
1525 · Under systemd, log to syslog only, not stderr, avoiding duplication
1526 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
1527 · Under systemd, remove unnecessary dependency on syslog.socket
1528 (fd.o #63531, Cristian Rodríguez)

1547 The "Disingenuous Assertions" release.
1549 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
1550 remains the recommended version for long-term-supported distributions
1551 or the upcoming GNOME 3.8 release.
1553 Build-time configuration changes:
1555 • The --with-dbus-session-bus-default-address configure option is no longer
1556 supported. Use the new --with-dbus-session-bus-connect-address and
1557 --with-dbus-session-bus-listen-address options instead. On Windows, you
1558 usually want them to have the same argument; on Unix, the defaults are
1561 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
1562 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
1563 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
1565 • cmake/cross-compile.sh has been removed. Instead, please use a
1566 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
1567 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
1568 as documented in "info automake Cross-Compilation", and set
1569 PKG_CONFIG_PATH appropriately.
1573 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
1574 • man2html is no longer used.
1578 • D-Bus Specification 0.20
1579 · actually say that /org/freedesktop/DBus is the object that
1580 implements o.fd.DBus (fd.o #51865, Colin Walters)
1581 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
1582 · stop claiming that all basic types work just like INT32 (strings don't!)

1585 the outdated duplicate copies used when building with CMake.
1586 (fd.o #59805; Ralf Habacker, Simon McVittie)
1590 • In the activation helper, when compiled for tests, do not reset the system
1591 bus address, fixing the regression tests. (fd.o #52202, Simon)
1593 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
1594 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
1596 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

1615 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
1618 · The default session bus listening and connecting address is now
1619 "autolaunch:", which makes D-Bus on Windows interoperate with itself
1620 and GDBus "out of the box". Use the configure options and cmake variables
1621 described above if you require a different autolaunch scope.
1622 (fd.o #38201, Simon McVittie)
1623 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
1625 • Create session.d, system.d directories under CMake (fd.o #41319,
1628 D-Bus 1.6.8 (2012-09-28)
1631 The "Fix one thing, break another" release.
1633 • Follow up to CVE-2012-3524: The additional hardening
1634 work to use __secure_getenv() as a followup to bug #52202
1635 broke certain configurations of gnome-keyring. Given
1636 the difficulty of making this work without extensive
1637 changes to gnome-keyring, use of __secure_getenv() is

1679 (fd.o #51032, Simon McVittie)
1681 • Disconnect "developer mode" (assertions, verbose mode etc.) from
1682 Automake maintainer mode. D-Bus developers should now configure with
1683 --enable-developer. Automake maintainer mode is now on by default;
1684 distributions can disable it with --disable-maintainer-mode.
1685 (fd.o #34671, Simon McVittie)
1687 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
1688 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)

1755 The “Big Book of Science” release.
1757 • Add public API to validate various string types:
1758 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
1759 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
1760 (fd.o #39549, Simon McVittie)
1762 • Turn DBusBasicValue into public API so bindings don't need to invent their
1763 own "union of everything" type (fd.o #11191, Simon McVittie)
1765 • Enumerate data files included in the build rather than using find(1)
1766 (fd.o #33840, Simon McVittie)
1768 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
1769 in dbus-daemon (fd.o #46273, Alban Crequy)
1772 · make dbus-daemon.exe --print-address (and --print-pid) work again
1773 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
1774 · fix duplicate case value when compiling against mingw-w64
1775 (fd.o #47321, Andoni Morales Alastruey)
1777 D-Bus 1.5.10 (2012-02-21)
1780 The "fire in Delerium" release.
1782 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
1783 and SUSv2) is now required.
1785 • D-Bus Specification 0.19:
1786 · Formally define unique connection names and well-known bus names,
1787 and document best practices for interface, bus, member and error names,
1788 and object paths (fd.o #37095, Simon McVittie)
1789 · Document the search path for session and system services on Unix, and
1790 where they should be installed by build systems (fd.o #21620, fd.o #35306;
1792 · Document the systemd transport (fd.o #35232, Lennart Poettering)
1794 • Make dbus_threads_init() use the same built-in threading implementation
1795 as dbus_threads_init_default(); the user-specified primitives that it
1796 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
1798 • Allow all configured auth mechanisms, not just one (fd.o #45106,
1801 • Improve cmake build system (Ralf Habacker):
1802 · simplify XML parser dependencies (fd.o #41027)
1803 · generate build timestamp (fd.o #41029)
1804 · only create batch files on Windows
1805 · fix option and cache syntax
1806 · add help-options target
1807 · share dbus-arch-deps.h.in with autotools rather than having our
1808 own version (fd.o #41033)
1810 • Build tests successfully with older GLib, as found in e.g. Debian 6
1811 (fd.o #41219, Simon McVittie)
1813 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
1815 • Build documentation correctly if man2html doesn't support filenames on
1816 its command-line (fd.o #43875, Jack Nagel)
1818 • Improve test coverage. To get even more coverage, run the tests with
1819 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
1821 • Reduce the size of the shared library by moving functionality only used
1822 by dbus-daemon, tests etc. into their internal library and deleting
1823 unused code (fd.o #34976, #39759; Simon McVittie)
1825 • Add dbus-daemon --nopidfile option, overriding the configuration, for
1826 setups where the default configuration must include <pidfile/> to avoid
1827 breaking traditional init, but the pid file is in fact unnecessary; use
1828 it under systemd to improve startup time a bit (fd.o #45520,
1831 • Optionally (if configured --with-valgrind) add instrumentation to debug
1832 libdbus and associated tools more meaningfully under Valgrind
1833 (fd.o #37286, Simon McVittie)
1835 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
1837 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
1839 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
1840 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
1841 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
1844 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
1848 · Replace our broken reimplementation of recursive mutexes, which has
1849 been broken since 2006, with an ordinary pthreads recursive mutex
1850 (fd.o #43744; Sigmund Augdal, Simon McVittie)
1851 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
1852 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
1853 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
1854 · When running under systemd, use it instead of ConsoleKit to check
1855 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
1856 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
1857 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
1858 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
1859 (fd.o #41218, Simon McVittie)
1860 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
1861 helper doesn't obey environment variables to avoid privilege escalation
1862 attacks, so make the system bus follow the same rules
1863 (fd.o #21620, Simon McVittie)
1866 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
1867 Jesper Dam, Ralf Habacker)
1868 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
1871 D-Bus 1.5.8 (2011-09-21)
1874 The "cross-metering" release.
1876 In addition to dead code removal and refactoring, this release contains all
1877 of the bugfixes from 1.4.16.
1879 • Clean up dead code, and make more warnings fatal in development builds
1880 (fd.o #39231, fd.o #41012; Simon McVittie)
1882 • If full test coverage is requested via --enable-tests, strictly require
1883 Python, pygobject and dbus-python, which are required by some tests; if not,
1884 and Python is missing, skip those tests rather than failing
1885 (fd.o #37847, Simon McVittie)
1887 • When using cmake, provide the same version-info API in the installed headers
1888 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
1890 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
1892 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
1894 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
1897 • Fix duplicates in authors list (Ralf Habacker)
1899 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
1900 (fd.o #39879, Chris Mayo)
1902 • Fix a small memory leak, and a failure to report errors, when updating
1903 a service file entry for activation (fd.o #39230, Simon McVittie)
1906 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
1907 Brian Cameron, Simon McVittie)
1908 · On systems that use libcap-ng but not systemd, drop supplemental groups
1909 when switching to the daemon user (Red Hat #726953, Steve Grubb)
1910 · Make the cmake build work again on GNU platforms (fd.o #29228,
1912 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
1913 like Solaris (fd.o #40313, Dagobert Michelsen)
1914 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
1915 (fd.o #40235, Simon McVittie)
1916 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
1917 (fd.o #39987, Simon McVittie)
1918 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
1919 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
1922 · Fix compilation on MSVC, which doesn't understand "inline" with its
1923 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
1924 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
1925 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
1927 D-Bus 1.5.6 (2011-07-29)
1930 The "weird, gravy-like aftertaste" release.
1932 In addition to new features and refactoring, this release contains all of the
1933 bugfixes from 1.4.14.
1935 Potentially incompatible (Bustle and similar debugging tools will need
1936 changes to work as intended):
1938 • Do not allow match rules to "eavesdrop" (receive messages intended for a
1939 different recipient) by mistake: eavesdroppers must now opt-in to this
1940 behaviour by putting "eavesdrop='true'" in the match rule, which will
1941 not have any practical effect on buses where eavesdropping is not allowed
1942 (fd.o #37890, Cosimo Alfarano)
1946 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
1947 Cosimo Alfarano, Simon McVittie)
1948 · add the "eavesdrop" keyword to match rules
1949 · define eavesdropping, unicast messages and broadcast messages
1950 · stop claiming that match rules are needed to match unicast messages to you
1951 · promote the type system to be a top-level section
1953 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
1954 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
1955 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
1957 • Consistently use atomic operations on everything that is ever manipulated
1958 via atomic ops, as was done for changes to DBusConnection's refcount in
1959 1.4.12 (fd.o #38005, Simon McVittie)
1961 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
1964 • Make "make check" in a clean tree work, by not running tests until
1965 test data has been set up (fd.o #34405, Simon McVittie)
1967 • The dbus-daemon no longer busy-loops if it has a very large number of file
1968 descriptors (fd.o #23194, Simon McVittie)
1970 • Refactor message flow through dispatching to avoid locking violations if
1971 the bus daemon's message limit is hit; remove the per-connection link cache,
1972 which was meant to improve performance, but now reduces it (fd.o #34393,
1975 • Some cmake fixes (Ralf Habacker)
1977 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
1978 Simon McVittie, Lennart Poettering)
1980 • Stop storing two extra byte order indicators in each D-Bus message
1981 (fd.o #38287, Simon McVittie)
1983 • Add an optional Stats interface which can be used to get statistics from
1984 a running dbus-daemon if enabled at configure time with --enable-stats
1985 (fd.o #34040, Simon McVittie)
1987 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
1989 • Documentation (fd.o #36156, Simon McVittie):
1990 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
1991 · install more documentation automatically, including man2html output
1992 · put dbus.devhelp in the right place (it must go in ${htmldir})
1995 · look for system services in /lib/dbus-1/system-services in addition to all
1996 the other well-known locations; note that this should always be /lib,
1997 even on platforms where shared libraries on the root FS would go in /lib64,
1998 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
1999 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2001 • Windows-specific (Ralf Habacker):
2002 · fix use of a mutex for autolaunch server detection
2003 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2005 D-Bus 1.5.4 (2011-06-10)
2008 Security (local denial of service):
2010 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2011 local DoS if foreign-endian messages are relayed through the dbus-daemon
2012 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2013 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2017 • The constant to use for an infinite timeout now has a name,
2018 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2019 which can be used for source compatibility with older versions of libdbus.
2021 • If GLib and DBus-GLib are already installed, more tests will be built,
2022 providing better coverage. The new tests can also be installed via
2023 ./configure --enable-installed-tests
2024 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2028 • Consistently use atomic operations for the DBusConnection's refcount,
2029 fixing potential threading problems (fd.o #38005, Simon McVittie)
2031 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2032 small (300KiB on x86-64) and it frequently doesn't work in unusual
2033 toolchains. To optimize for minimum installed size, you should benchmark
2034 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2035 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2037 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2038 (fd.o #35880, Timothy Redaelli)
2040 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2041 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2043 • Windows-specific changes:
2044 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2046 D-Bus 1.5.2 (2011-06-01)
2049 The "Boar Hunter" release.
2051 Notes for distributors:
2053 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2054 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2055 toolchain supports it reliably, via something like:
2057 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2059 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2063 • D-Bus Specification v0.17
2064 · Reserve the extra characters used in signatures by GVariant
2065 (fd.o #34529, Simon McVittie)
2066 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2067 • Don't force -fPIE: distributions and libtool know better than we do whether
2068 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2069 • Allow --disable-gc-sections, in case your toolchain offers the
2070 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2071 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2072 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2073 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2074 • Ensure that maintainers upload documentation with the right permissions
2075 (fd.o #36130, Simon McVittie)
2076 • Don't force users of libdbus to be linked against -lpthread, -lrt
2077 (fd.o #32827, Simon McVittie)
2078 • Log system-bus activation information to syslog (fd.o #35705,
2080 • Log messages dropped due to quotas to syslog (fd.o #35358,
2082 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
2083 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
2084 (fd.o #35228, Lennart Poettering)
2085 • In the regression tests, don't report fds as "leaked" if they were open
2086 on startup (fd.o #35173, Simon McVittie)
2087 • Make dbus-monitor bail out if asked to monitor more than one bus,
2088 rather than silently using the last one (fd.o #26548, Will Thompson)
2089 • Clarify documentation (fd.o #35182, Simon McVittie)
2090 • Clean up minor dead code and some incorrect error handling
2091 (fd.o #33128, fd.o #29881; Simon McVittie)
2092 • Check that compiler options are supported before using them (fd.o #19681,
2095 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
2097 D-Bus 1.5.0 (2011-04-11)
2100 The "you never know when you need to tow something from your giant
2101 flying shark" release.
2103 • D-Bus Specification v0.16
2104 · Add support for path_namespace and arg0namespace in match rules
2105 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
2106 · Make argNpath support object paths, not just object-path-like strings,
2107 and document it better (fd.o #31818, Will Thompson)
2108 • Let the bus daemon implement more than one interface (fd.o #33757,
2110 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2112 • Require user intervention to compile with missing 64-bit support
2113 (fd.o #35114, Simon McVittie)
2114 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
2115 • Raise UnknownObject instead of UnknownMethod for calls to methods on
2116 paths that are not part of the object tree, and UnknownInterface for calls
2117 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
2119 D-Bus 1.4.8 (2011-04-08)
2122 The "It's like the beginning of a lobster" release.
2124 • Rename configure.in to configure.ac, and update it to modern conventions
2125 (fd.o #32245; Javier Jardón, Simon McVittie)
2126 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
2128 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
2129 --disable-x11-autolaunch configure option to prevent it altogether
2130 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
2131 • Install the documentation, and an index for Devhelp (fd.o #13495,
2132 Debian #454142; Simon McVittie, Matthias Clasen)
2133 • If checks are not disabled, check validity of string-like types and
2134 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
2135 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
2136 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
2137 • Break up a huge conditional in config-parser so gcov can produce coverage
2138 data (fd.o #10887, Simon McVittie)
2139 • List which parts of the Desktop Entry specification are applicable to
2140 .service files (fd.o #19159, Sven Herzberg)
2141 • Don't suppress service activation if two services have the same Exec=
2142 (fd.o #35750, Colin Walters)
2144 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
2146 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
2147 (fd.o #32805, Mark Brand)
2149 D-Bus 1.4.6 (2010-02-17)
2152 The "1, 2, miss a few, 99, 100" release.
2154 • Remove unfinished changes intended to support GTest-based tests,
2155 which were mistakenly included in 1.4.4
2157 D-Bus 1.4.4 (2010-02-17)
2160 • Switch back to using even micro versions for stable releases; 1.4.1
2161 should have been called 1.4.2, so skip that version number
2162 • Don't leave bad file descriptors being watched when spawning processes,
2163 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
2164 also LP#656134, LP#680444, LP#713157)
2165 • Check for MSG_NOSIGNAL correctly
2166 • Fix failure to detect abstract socket support (fd.o #29895)
2167 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
2168 (fd.o #32262, NB#180486)
2169 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,

2173 • Improve gcc malloc annotations (fd.o #32710)
2174 • If the system bus is launched via systemd, protect it from the OOM killer
2175 • Documentation improvements (fd.o #11190)

2198 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
2199 crash the bus. The existing restriction to 64-levels of nesting previously
2200 only applied to the static type signature; now it also applies to dynamic
2201 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
2203 • OS X portability fixes, including launchd support.
2204 • Windows autolaunch improvements.
2205 • Various bug fixes.
