1 D-Bus 1.10.20 (2017-06-29)
4 The “suggesting a delivery gone horribly wrong” release.
8 • Fix a reference leak when blocking on a pending call on a connection
9 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
11 • Don't put timestamps in the Doxygen-generated documentation, for
12 closer-to-reproducible builds (fd.o #100692, Simon McVittie)
14 • Avoid an assertion failure when connecting to a semicolon-separated
15 series of addresses, one of which fails (fd.o #101257, Simon McVittie)
19 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
20 (fd.o #100715, Simon McVittie)
22 D-Bus 1.10.18 (2017-04-05)
25 The “can't handle a self-referential paradox” release.
29 • Re-order dbus-daemon startup so that on SELinux systems, the thread
30 that reads AVC notifications retains the ability to write to the
31 audit log (fd.o #92832, Debian #857660; Laurent Bigonville)
33 • Fix a harmless read overflow and some memory leaks in a unit test
34 (fd.o #100568, Philip Withnall)
36 D-Bus 1.10.16 (2017-02-16)
39 The “super digging powers” release.
41 The fixes in this release are arguably security fixes, but if they
42 affect you, please take this opportunity to rethink how you are
47 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
48 stable and Debian testing in addition to the older Ubuntu that is
49 the default (fd.o #98889, Simon McVittie)
53 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
54 allow an attacker to overwrite a file named "nonce", in a directory
55 that the user running dbus-daemon can write, with a random value
56 known only to the user running dbus-daemon. This is unlikely to be
57 exploitable in practice, particularly since the nonce-tcp transport
58 is really only useful on Windows.
60 On Unix systems we strongly recommend using only the unix: and systemd:
61 transports, together with EXTERNAL authentication. These are the only
62 transports and authentication mechanisms enabled by default.
64 (fd.o #99828, Simon McVittie)
66 • Avoid symlink attacks in the "embedded tests", which are not enabled
67 by default and should never be enabled in production builds of dbus.
68 (fd.o #99828, Simon McVittie)
70 D-Bus 1.10.14 (2016-11-28)
73 The “Well, other bands know more than three chords” release.
77 • Work around an undesired effect of the fix for CVE-2014-3637
78 (fd.o #80559), in which processes that frequently send fds, such as
79 logind during a flood of new PAM sessions, can get disconnected for
80 continuously having at least one fd "in flight" for too long;
81 dbus-daemon interprets that as a potential denial of service attack.
82 The workaround is to disable that check for uid 0 process such as
83 logind, with a message in the system log. The bug remains open while
84 we look for a more general solution.
85 (fd.o #95263, LP#1591411; Simon McVittie)
87 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
88 was disabled at compile time. That test is not expected to work
89 in that configuration. (fd.o #98665, Simon McVittie)
91 D-Bus 1.10.12 (2016-10-10)
94 The “not excessively inhospitable” release.
98 • Do not treat ActivationFailure message received from root-owned systemd
99 name as a format string. In principle this is a security vulnerability,
100 but we do not believe it is exploitable in practice, because only
101 privileged processes can own the org.freedesktop.systemd1 bus name, and
102 systemd does not appear to send activation failures that contain "%".
104 Please note that this probably *was* exploitable in dbus versions
105 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
106 the time was only thought to be a denial of service vulnerability
107 (CVE-2015-0245). If you are still running one of those versions,
108 patch or upgrade immediately.
110 (fd.o #98157, Simon McVittie)
114 • Harden dbus-daemon against malicious or incorrect ActivationFailure
115 messages by rejecting them if they do not come from a privileged
116 process, or if systemd activation is not enabled
117 (fd.o #98157, Simon McVittie)
119 • Avoid undefined behaviour when setting reply serial number without going
120 via union DBusBasicValue (fd.o #98035, Marc Mutz)
122 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
124 D-Bus 1.10.10 (2016-08-15)
127 The “tungsten door” release.
131 • On Linux, when dbus-daemon is run with reduced susceptibility to the
132 OOM killer (typically via systemd), do not let child processes inherit
133 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
135 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
136 contains a semicolon (fd.o #94746, Thiago Macieira)
138 • Fix memory leaks and thread safety in subprocess starting on Windows
139 (fd.o #95191, Ralf Habacker)
141 • Do not require systemd to have a service file if using it for activation
142 (fd.o #93194; Simon McVittie; backport from 1.11.0)
144 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
145 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
147 • In tests that exercise correct handling of crashing D-Bus services,
148 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
150 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
152 • update-activation-environment: produce better diagnostics on error
153 (fd.o #96653, Simon McVittie)
155 • Don't fail the build with an unused const variable warning under gcc 6
156 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
158 • Merge dbus-1.10-ci branch, containing backports from 1.11.0 in build/test
159 code to support continuous integration (fd.o #93194, Simon McVittie)
161 · Avoid -Wunused-label when compiling with libselinux but no libaudit
162 · In development builds, allow OOM tests to be disabled as documented
163 · Accept and ignore the --tap argument in all "embedded tests", and run
164 all automated tests with that argument for better diagnostics
165 · Fix the systemd activation test under CMake by installing the required
167 · In Automake, fix shell syntax for installcheck-local with no DESTDIR
168 · In Automake, don't try to run manual tests in installcheck
169 · In CMake, don't run manual-tcp test as an automated test
170 · Add travis-ci.org build machinery
172 D-Bus 1.10.8 (2016-03-07)
175 The “digestive biscuits” release.
179 • Enable "large file support" on systems where it exists: dbus-daemon
180 is not expected to open large files, but it might need to stat files
181 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
183 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
184 which might result in a pedantic C compiler not copying the entire contents
185 of a DBusMessageIter; statically assert that this is not an ABI change
186 in practice (fd.o #94136, Simon McVittie)
188 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
189 (fd.o #94244, Dmitri Iouchtchenko)
191 • Correctly report test failures in C tests from run-test.sh
192 (fd.o #93379; amit tewari, Simon McVittie)
194 • When tests are enabled, run all the marshal-validate tests, not just
195 the even-numbered ones (fd.o #93908, Nick Lewycky)
197 • Correct the expected error from one marshal-validate test, which was
198 previously not run due to the above bug (fd.o #93908, Simon McVittie)
200 D-Bus 1.10.6 (2015-12-01)
203 The “marzipan beetles” release.
207 • On Unix when running tests as root, don't assert that root and
208 the dbus-daemon user can still call UpdateActivationEnvironment;
209 assert that those privileged users can call BecomeMonitor instead
210 (fd.o #93036, Simon McVittie)
212 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
215 • On Windows Autotools builds, don't run tests that rely on
216 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
218 D-Bus 1.10.4 (2015-11-17)
221 The “Frostburn Canyon” release.
225 • GetConnectionCredentials, GetConnectionUnixUser and
226 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
227 will now return details of the dbus-daemon itself. This is required
228 to be able to call SetEnvironment on systemd.
229 (fd.o #92857, Jan Alexander Steffens)
233 • Make UpdateActivationEnvironment always fail with AccessDenied on the
234 system bus. Previously, it was possible to configure it so root could
235 call it, but the environment variables were not actually used,
236 because the launch helper would discard them.
237 (fd.o #92857, Jan Alexander Steffens)
239 • On Unix with --systemd-activation on a user bus, make
240 UpdateActivationEnvironment pass on its arguments to systemd's
241 SetEnvironment method, solving inconsistency between the environments
242 used for traditional activation and systemd user-service activation.
243 (fd.o #92857, Jan Alexander Steffens)
245 • On Windows, don't crash if <syslog/> or --syslog is used
246 (fd.o #92538, Ralf Habacker)
248 • On Windows, fix a memory leak when setting a DBusError from a Windows
249 error (fd.o #92721, Ralf Habacker)
251 • On Windows, don't go into infinite recursion if we abort the process
252 with backtraces enabled (fd.o #92721, Ralf Habacker)
254 • Fix various failing tests, variously on Windows and cross-platform:
255 · don't test system.conf features (users, groups) that only make sense
256 on the system bus, which is not supported on Windows
257 · don't call _dbus_warn() when we skip a test, since it is fatal
258 · fix computation of expected <standard_session_servicedirs/>
259 · when running TAP tests, translate newlines to Unix format, fixing
260 cross-compiled tests under Wine on Linux
261 · don't stress-test refcounting under Wine, where it's really slow
262 · stop assuming that a message looped-back to the test will be received
264 · skip some system bus tests on Windows since they make no sense there
265 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
267 D-Bus 1.10.2 (2015-10-26)
270 The “worst pies in London” release.
274 • Correct error handling for activation: if there are multiple attempts
275 to activate the same service and it fails immediately, the first attempt
276 would get the correct reply, but the rest would time out. We now send
277 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
279 • If BecomeMonitor is called with a syntactically invalid match rule,
280 don't crash with an assertion failure, fixing a regression in 1.9.10.
281 This was not exploitable as a denial of service, because the check
282 for a privileged user is done first. (fd.o #92298, Simon McVittie)
284 • On Linux with --enable-user-session, add the bus address to the
285 environment of systemd services for better backwards compatibility
286 (fd.o #92612, Jan Alexander Steffens)
288 • On Windows, fix the logic for replacing the installation prefix
289 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
291 • On Windows, if installed in the conventional layout with ${prefix}/etc
292 and ${prefix}/share, use relative paths between bus configuration files
293 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
295 • Make more of the regression tests pass in Windows builds (fd.o #92538,
298 D-Bus 1.10.0 (2015-08-25)
303 This is a new stable branch, recommended for use in OS distributions.
307 • distribute test/tap-test.sh.in, even if the tarball was built without
308 tests enabled (fd.o #91684, Simon McVittie)
309 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
311 Summary of major changes since 1.8.0:
313 • The basic setup for the well-known system and session buses is
314 now done in read-only files in ${datadir} (normally /usr/share).
315 See the NEWS entry for 1.9.18 for details.
317 • AppArmor integration has been merged, with features similar to the
318 pre-existing SELinux integration. It is mostly compatible with the
319 patches previously shipped by Ubuntu, with one significant change:
320 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
321 by GetConnectionCredentials and was not included.
323 • The --enable-user-session configure option can be enabled
324 by OS integrators intending to use systemd to provide a session bus
325 per user (in effect, treating all concurrent graphical and non-graphical
326 login sessions as one large session).
328 • The new listenable address mode "unix:runtime=yes" listens on
329 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
330 user session. libdbus and "dbus-launch --autolaunch" will connect to
331 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
334 • All executables are now dynamically linked to libdbus-1.
335 Previously, some executables, most notably dbus-daemon, were statically
336 linked to a specially-compiled variant of libdbus. This results in
337 various private functions in the _dbus namespace being exposed by the
338 shared library. These are not API, and must not be used outside
339 the dbus source tree.
341 • On platforms with ELF symbol versioning, all public symbols
342 are versioned LIBDBUS_1_3.
346 • org.freedesktop.DBus.GetConnectionCredentials returns
347 LinuxSecurityLabel where supported
348 • org.freedesktop.DBus.Monitoring interface (privileged)
349 · BecomeMonitor method supersedes match rules with eavesdrop=true,
350 which are now deprecated
351 • org.freedesktop.DBus.Stats interface (semi-privileged)
352 · now enabled by default
353 · new GetAllMatchRules method
354 • org.freedesktop.DBus.Verbose interface (not normally compiled)
355 · toggles the effect of DBUS_VERBOSE
360 • dbus-update-activation-environment
362 New optional dependencies:
364 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
365 • Complete documentation requires Ducktype and yelp-tools
366 • Full test coverage requires GLib 2.36 and PyGI
367 • AppArmor integration requires libapparmor and optionally libaudit
369 Dependencies removed:
373 D-Bus 1.9.20 (2015-08-06)
376 The “Remember Tomorrow” release.
378 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
383 • Don't second-guess what the ABI of poll() is, allowing it to be used
384 on Integrity RTOS and other unusual platforms (fd.o #90314;
385 Rolland Dudemaine, Simon McVittie)
387 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
388 both enabled (fd.o #89225, Simon McVittie)
390 • Log audit events for AppArmor/SELinux policy violations whenever
391 we have CAP_AUDIT_WRITE, even if not the system bus
392 (fd.o #83856, Laurent Bigonville)
394 D-Bus 1.9.18 (2015-07-21)
397 The “Pirate Elite” release.
399 Configuration changes:
401 • The basic setup for the well-known system and session buses is now done
402 in read-only files in ${datadir}, moving a step closer to systems
403 that can operate with an empty /etc directory. In increasing order
406 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
407 the default message policies.
408 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
409 dbus still installs a trivial version of each, for documentation
410 purposes; putting configuration directives in these files is deprecated.
411 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
412 to install "drop-in" configuration snippets (any packages
413 using those directories should explicitly depend on at least this
415 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
416 or third-party software to install "drop-in" configuration snippets
417 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
420 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
421 and "s*" refers to either system or session as appropriate.
423 (fd.o #89280, Dimitri John Ledkov)
427 • Fix a memory leak when GetConnectionCredentials() succeeds
428 (fd.o #91008, Jacek Bukarewicz)
430 • Ensure that dbus-monitor does not reply to messages intended for others,
431 resulting in its own disconnection (fd.o #90952, Simon McVittie)
433 D-Bus 1.9.16 (2015-05-14)
436 The “titanium barns” release.
440 • Automake 1.13 is now required when compiling from git or modifying
445 • On Unix platforms, change the default configuration for the session bus
446 to only allow EXTERNAL authentication (secure kernel-mediated
447 credentials-passing), as was already done for the system bus.
449 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
450 unpredictable pseudo-random numbers.
452 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
453 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
454 NFS or similar, you will need to reconfigure the session bus to accept
455 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
458 (fd.o #90414, Simon McVittie)
460 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
461 transport, UUIDs or any other reason, fail if we cannot obtain entropy
462 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
463 occurs, instead of silently falling back to low-entropy pseudorandom
464 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
468 • Add dbus_message_iter_get_element_count()
469 (fd.o #30350; Christian Dywan, Simon McVittie)
471 • Introduce new internal DBusSocket and DBusPollable types so we can
472 stop treating the Windows SOCKET type as if it was int. DBusSocket
473 is specifically a socket, cross-platform. DBusPollable is whatever
474 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
475 (fd.o #89444; Ralf Habacker, Simon McVittie)
477 • All regression tests now output TAP <https://testanything.org/>
478 (fd.o #89846, Simon McVittie)
480 • Internal APIs consistently use signed values for timestamps
481 (fd.o #18494, Peter McCurdy)
483 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
484 (fd.o #88812, Simon McVittie)
486 • Clean up a lot of compiler warnings
487 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
491 • Add locking to DBusCounter's reference count and notify function
492 (fd.o #89297, Adrian Szyndela)
494 • Ensure that DBusTransport's reference count is protected by the
495 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
497 • Correctly release DBusServer mutex before early-return if we run out
498 of memory while copying authentication mechanisms (fd.o #90021,
501 • Make dbus-test-tool and dbus-update-activation-environment portable
502 to Windows (fd.o #90089, Ralf Habacker)
504 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
505 Ralf Habacker, Simon McVittie)
507 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
510 • Clean up some memory and fd leaks in test code and tools
511 (fd.o #90021, Ralf Habacker)
513 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
514 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
516 • CMake generates a versioned shared library even if the revision is 0,
517 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
519 D-Bus 1.9.14 (2015-03-02)
522 The “don't stand in the poison cloud” release.
526 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
527 were previously linked to a static version of libdbus.
529 • The tests no longer require dbus-glib in order to exercise the libdbus
530 shared library; they are always linked to libdbus now.
532 Build-time configuration:
534 • The new --enable-user-session option, off by default, can be enabled
535 by OS integrators intending to use systemd to provide a session bus
536 per user (in effect, treating all concurrent graphical and non-graphical
537 login sessions as one large session)
541 • All executables are now linked dynamically to libdbus.
542 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
544 • On platforms that support them (GNU libc and possibly others),
545 libdbus now has versioned symbols for its public API.
546 All public symbols (visible in the header files) are currently
547 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
548 dbus_internal have a version that changes with each release, and
549 must not be used by applications. (also fd.o #83115)
551 • New listenable address mode "unix:runtime=yes" which listens on
552 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
553 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
555 • Add optional systemd units for a per-user bus listening on
556 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
558 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
559 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
562 • New dbus-update-activation-environment tool uploads environment
563 variables to "dbus-daemon --session" and optionally "systemd --user",
564 primarily as a way to keep the per-user bus compatible with
565 distributions' existing X11 login scripts (also fd.o #61301)
567 • <includedir/> elements in dbus-daemon configuration are now silently
568 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
570 • Add microsecond-resolution timestamps to the default output of
571 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
575 • Fix a race condition in the 'monitor' test introduced in 1.9.10
576 (fd.o #89222, Simon McVittie)
578 D-Bus 1.9.12 (2015-02-19)
581 The “monster lasagna” release.
585 • Ducktype and yelp-tools are now required to build complete documentation
586 (they are optional for normal builds).
590 • D-Bus Specification version 0.26
591 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
592 · document the BecomeMonitor method
594 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
595 (fd.o #89041; Tyler Hicks, Simon McVittie)
597 • On Linux, add support for AppArmor mediation of message sending and
598 receiving and name ownership (paralleling existing SELinux mediation
599 support), and eavesdropping (a new check, currently AppArmor-specific)
600 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
602 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
603 that have printable ASCII contents; we previously only did this for
604 unterminated bytestrings (fd.o #89109, Simon McVittie)
606 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
608 • On Windows, add WindowsSID to GetConnectionCredentials
609 (fd.o #54445, Ralf Habacker)
611 • Improve clarity of dbus-monitor --profile output and add more columns
612 (fd.o #89165, Ralf Habacker)
614 • Add a man page for dbus-test-tool, and build it under CMake as well
615 as Autotools (fd.o#89086, Simon McVittie)
617 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
618 to control it at runtime, overriding the DBUS_VERBOSE environment variable
619 (fd.o #88896, Ralf Habacker)
623 • Reduce the number of file descriptors used in the fd-passing test,
624 avoiding failure under the default Linux fd limit, and automatically
625 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
627 D-Bus 1.9.10 (2015-02-09)
630 The “sad cyborgs” release.
632 Security fixes merged from 1.8.16:
634 • Do not allow non-uid-0 processes to send forged ActivationFailure
635 messages. On Linux systems with systemd activation, this would
636 allow a local denial of service: unprivileged processes could
637 flood the bus with these forged messages, winning the race with
638 the actual service activation and causing an error reply
639 to be sent back when service auto-activation was requested.
640 This does not prevent the real service from being started,
641 so the attack only works while the real service is not running.
642 (CVE-2015-0245, fd.o #88811; Simon McVittie)
646 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
647 similar tools receive messages without altering the security properties
648 of the system bus, by calling the new BecomeMonitor method on a
649 private connection. This bypasses the normal <allow> and <deny> rules
650 entirely, so to preserve normal message-privacy assumptions, only root
651 is allowed to do this on the system bus. Restricted environments,
652 such as Linux with LSMs, should lock down access to the Monitoring
653 interface. (fd.o #46787, Simon McVittie)
655 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
656 dbus-daemon supports it and access permissions allow it.
657 It still supports the previous approach ("eavesdropping" match rules)
658 for compatibility with older bus daemons. (fd.o #46787, Simon)
660 • dbus-monitor can now log the message stream as binary data for later
661 analysis, with either no extra framing beyond the normal D-Bus headers,
662 or libpcap-compatible framing treating each D-Bus message
663 as a captured packet. (fd.o #46787, Simon)
667 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
669 • On Unix, forcibly terminate regression tests after 60 seconds to
670 prevent them from blocking continuous integration frameworks
673 D-Bus 1.9.8 (2015-02-03)
676 The “all the types of precipitation” release.
680 • full test coverage now requires GLib 2.36
681 • full test coverage now requires PyGI (PyGObject 3,
682 "import gi.repository.GObject") instead of the
683 obsolete PyGObject 2 ("import gobject")
687 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
689 • better regression test coverage, including systemd activation
690 (fd.o #57952, #88810; Simon McVittie)
694 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
695 turned off (fd.o #88808, Simon McVittie)
697 • TCP sockets on Windows no longer fail to listen approximately 1 time
698 in 256, caused by a logic error that should have always made it fail but
699 was mitigated by incorrect endianness for the port number
700 (fd.o #87999, Ralf Habacker)
702 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
704 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
705 previous 64, completing a previous fix which only worked under
706 Autotools (fd.o #71297, Ralf Habacker)
708 • on Windows, if the IP family is unspecified only use IPv4,
709 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
711 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
713 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
715 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
718 D-Bus 1.9.6 (2015-01-05)
721 The “I do have a bread knife” release.
725 • Do not allow calls to UpdateActivationEnvironment from uids other than
726 the uid of the dbus-daemon. If a system service installs unsafe
727 security policy rules that allow arbitrary method calls
728 (such as CVE-2014-8148) then this prevents memory consumption and
729 possible privilege escalation via UpdateActivationEnvironment.
731 We believe that in practice, privilege escalation here is avoided
732 by dbus-daemon-launch-helper sanitizing its environment; but
733 it seems better to be safe.
735 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
736 on object paths other than /org/freedesktop/DBus. Some system services
737 install unsafe security policy rules that allow arbitrary method calls
738 to any destination, method and interface with a specified object path;
739 while less bad than allowing arbitrary method calls, these security
740 policies are still harmful, since dbus-daemon normally offers the
741 same API on all object paths and other system services might behave
746 • Add missing initialization so GetExtendedTcpTable doesn't crash on
747 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
749 D-Bus 1.9.4 (2014-11-24)
752 The “extra-sturdy caramel” release.
756 • Partially revert the CVE-2014-3639 patch by increasing the default
757 authentication timeout on the system bus from 5 seconds back to 30
758 seconds, since this has been reported to cause boot regressions for
759 some users, mostly with parallel boot (systemd) on slower hardware.
761 On fast systems where local users are considered particularly hostile,
762 administrators can return to the 5 second timeout (or any other value
763 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
766 <limit name="auth_timeout">5000</limit>
769 (fd.o #86431, Simon McVittie)
771 • Add a message in syslog/the Journal when the auth_timeout is exceeded
772 (fd.o #86431, Simon McVittie)
774 • Send back an AccessDenied error if the addressed recipient is not allowed
775 to receive a message (and in builds with assertions enabled, don't
776 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
778 D-Bus 1.9.2 (2014-11-10)
781 The “structurally unsound flapjack” release.
785 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
786 so that CVE-2014-3636 part A cannot exhaust the system bus'
787 file descriptors, completing the incomplete fix in 1.8.8.
788 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
792 • D-Bus Specification version 0.25
793 · new value 'const' for EmitsChangedSignal annotation
794 (fd.o #72958, Lennart Poettering)
795 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
796 (fd.o #83449; Lennart Poettering, Simon McVittie)
797 · annotate table of types with reserved/basic/container, and for
798 basic types, fixed/string-like
799 · clarify arbitrary limits by quoting them in mebibytes
801 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
802 (fd.o #83449, Simon McVittie)
804 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
805 useful for debugging and performance testing:
806 · dbus-test-tool spam: send repeated messages
807 · dbus-test-tool echo: send an empty reply for all method calls
808 · dbus-test-tool black-hole: do not reply to method calls
809 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
811 • Add support for process ID in credentials-passing on NetBSD
812 (fd.o #69702, Patrick Welche)
814 • Add an example script to find potentially undesired match rules
815 (fd.o #84598, Alban Crequy)
817 • Document the central assumption that makes our use of credentials-passing
818 secure (fd.o #83499, Simon McVittie)
820 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
821 and add some links to GDBus and QtDBus documentation (fd.o #25140,
826 • Use a less confusing NoReply message when disconnected with a reply pending
827 (fd.o #76112, Simon McVittie)
829 • Make the .pc file relocatable by letting pkg-config do all variable
830 expansion itself (fd.o #75858, Руслан Ижбулатов)
832 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
833 (fd.o #85563, Patrick Welche)
835 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
837 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
838 do not lose the exec() errno (fd.o #24821, Simon McVittie)
840 • Do not fail the tests if a parent process has leaked non-close-on-exec
841 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
843 • Do not fail the tests on Unix platforms with incomplete
844 credentials-passing support, but do fail if we can't pass credentials
845 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
846 (fd.o #69702, Simon McVittie)
848 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
849 when building with cmake, and expand test coverage there
850 (fd.o #73689; Ralf Habacker, Simon McVittie)
852 D-Bus 1.9.0 (2014-10-01)
855 The “tiered cheeses” release.
859 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
860 requires either the libsystemd or libsd-daemon shared library, dropping the
861 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
863 Build-time configuration changes:
865 • The Stats interface is now enabled by default, and locked-down to
866 root-only on the system bus. Configure with --disable-stats
867 to disable it altogether on memory- or disk-constrained systems,
868 or see ${docdir}/examples/ to open it up to non-root users on the
869 system bus or restrict access on the session bus.
870 (fd.o #80759; Simon McVittie, Alban Crequy)
872 • The CMake build system now builds the same shared library name as Autotools
873 on at least Linux and Windows:
874 - on Linux (and perhaps other Unix platforms), it previously built
875 libdbus-1.so, but now builds libdbus-1.so.3.* with development
876 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
877 - on Windows, it previously built either libdbus-1.dll (release) or
878 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
879 libdbus-1.dll for compatibility with older applications.
880 (fd.o #74117, Ralf Habacker)
884 • D-Bus Specification version 0.24
885 · document how to quote match rules (fd.o #24307, Simon McVittie)
886 · explicitly say that most message types never expect a reply
887 regardles of whether they have NO_REPLY_EXPECTED
888 (fd.o #75749, Simon McVittie)
890 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
891 initial latency (fd.o #75544, Matt Hoosier)
893 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
894 (fd.o #69702, Patrick Welche)
896 • in dbus-monitor, print more information about file descriptors
897 (fd.o #80603, Alban Crequy)
899 • do not install system bus configuration if built for Windows
900 (fd.o #83583; Ralf Habacker, Simon McVittie)
902 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
904 • Add a regression test for file descriptor passing (fd.o #83622,
909 • fix an incorrect error message if a Unix socket path is too long
910 (fd.o #73887, Antoine Jacoutot)
912 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
913 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
915 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
916 in ps(1) (fd.o #69716, Chengwei Yang)
918 • avoid calling poll() with timeout < -1, which is considered invalid
919 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
921 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
922 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
923 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
925 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
927 • Documentation improvements
928 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
930 • in dbus-monitor, do not leak file descriptors that we have monitored
931 (fd.o #80603, Alban Crequy)
933 • Set the close-on-exec flag for the inotify file descriptor, even
934 if built with CMake or older libc (fd.o #73689, Simon McVittie)
936 • Remove some LGPL code from the Windows dbus-daemon
937 (fd.o #57272, Ralf Habacker)
939 D-Bus 1.8.8 (2014-09-16)
942 The "smashy smashy egg man" release.
946 • Do not accept an extra fd in the padding of a cmsg message, which
947 could lead to a 4-byte heap buffer overrun.
948 (CVE-2014-3635, fd.o #83622; Simon McVittie)
950 • Reduce default for maximum Unix file descriptors passed per message
951 from 1024 to 16, preventing a uid with the default maximum number of
952 connections from exhausting the system bus' file descriptors under
953 Linux's default rlimit. Distributors or system administrators with a
954 more restrictive fd limit may wish to reduce these limits further.
956 Additionally, on Linux this prevents a second denial of service
957 in which the dbus-daemon can be made to exceed the maximum number
958 of fds per sendmsg() and disconnect the process that would have
960 (CVE-2014-3636, fd.o #82820; Alban Crequy)
962 • Disconnect connections that still have a fd pending unmarshalling after
963 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
964 removing the possibility of creating an abusive connection that cannot be
965 disconnected by setting up a circular reference to a connection's
967 (CVE-2014-3637, fd.o #80559; Alban Crequy)
969 • Reduce default for maximum pending replies per connection from 8192 to 128,
970 mitigating an algorithmic complexity denial-of-service attack
971 (CVE-2014-3638, fd.o #81053; Alban Crequy)
973 • Reduce default for authentication timeout on the system bus from
974 30 seconds to 5 seconds, avoiding denial of service by using up
975 all unauthenticated connection slots; and when all unauthenticated
976 connection slots are used up, make new connection attempts block
977 instead of disconnecting them.
978 (CVE-2014-3639, fd.o #80919; Alban Crequy)
982 • Check for libsystemd from systemd >= 209, falling back to
983 the older separate libraries if not found (Umut Tezduyar Lindskog,
986 • On Linux, use prctl() to disable core dumps from a test executable
987 that deliberately raises SIGSEGV to test dbus-daemon's handling
988 of that condition (fd.o #83772, Simon McVittie)
990 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
993 • Improve documentation for running tests on Windows (fd.o #41252,
996 D-Bus 1.8.6 (2014-06-02)
1001 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1002 the message. This prevents an attack in which a malicious client can
1003 make dbus-daemon disconnect a system service, which is a local
1005 (fd.o #80163, CVE-2014-3532; Alban Crequy)
1007 • Track remaining Unix file descriptors correctly when more than one
1008 message in quick succession contains fds. This prevents another attack
1009 in which a malicious client can make dbus-daemon disconnect a system
1011 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
1012 Simon McVittie, Alban Crequy)
1016 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
1017 attach to a session, kill the dbus-daemon as intended
1018 (fd.o #74698, Роман Донченко)
1020 D-Bus 1.8.4 (2014-06-10)
1025 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1026 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1027 Additionally, in highly unusual environments the same flaw could lead to
1028 a side channel between processes that should not be able to communicate.
1029 (CVE-2014-3477, fd.o #78979)
1031 D-Bus 1.8.2 (2014-04-30)
1034 The “nobody wants red” release.
1038 • in the CMake build system, add some hints for Linux users cross-compiling
1039 Windows D-Bus binaries to be able to run tests under Wine
1040 (fd.o #41252, Ralf Habacker)
1042 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
1046 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
1047 to /var/lib/dbus/machine-id instead of generating an entirely new ID
1048 (fd.o #77941, Simon McVittie)
1050 • if dbus-launch receives an X error very quickly, do not kill
1051 unrelated processes (fd.o #74698, Роман Донченко)
1053 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
1054 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
1056 • cope with \r\n newlines in regression tests, since on Windows,
1057 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
1059 D-Bus 1.8.0 (2014-01-20)
1062 The “Wolverine distrusts my printer” release.
1064 This starts a new stable branch. The 1.6.x branch is now considered to be
1065 outdated, and will only receive fixes for serious bugs such as security
1066 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1067 are unlikely to get any more releases, but if distributors still need to
1068 support them, please share security patches via upstream.
1070 Summary of changes since 1.6.x:
1072 • libdbus always behaves as if dbus_threads_init_default() had been called
1073 (thread-safety by default)
1074 • new dbus-run-session tool, replacing certain misuses of dbus-launch
1075 • dbus-monitor can talk to outdated versions of dbus-daemon again
1076 • new org.freedesktop.DBus.GetConnectionCredentials method
1077 • GetConnectionUnixProcessID also works correctly on Windows, returning
1078 the Windows process ID
1079 • GetConnectionWindowsSID returns the correct SID on Windows
1080 • expat is required, libxml2 can no longer be used as a substitute
1081 • the userDB cache is required, and cannot be disabled
1082 • a 64-bit integer type (either int, long, long long or _int64) is required
1083 • better systemd-journald integration on Linux
1084 • fixed long-standing fd and array leaks when failing to parse a message
1085 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
1086 when using certain object-path allocation patterns, notably in Avahi
1087 • better defaults for Windows support
1088 • better CMake support
1089 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
1090 • the source language for the man pages is now Docbook XML
1092 Enhancements since 1.7.10:
1094 • Enhance the CMake build system to check for GLib and compile/run
1095 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
1099 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
1102 • fix compilation of systemd journal support on older systemd versions where
1103 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
1105 • fix compilation on older MSVC versions by including stdlib.h
1106 (fd.o #73455, Ralf Habacker)
1108 • Allow <allow_anonymous/> to appear in an included configuration file
1109 (fd.o #73475, Matt Hoosier)
1111 Test behaviour changes since 1.7.10:
1113 • If the tests crash with an assertion failure, they no longer default to
1114 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
1115 environment if you want the old behaviour.
1117 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
1118 can be run with an external dbus-daemon by setting
1119 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
1120 an unusually-configured dbus-daemon are skipped.
1122 D-Bus 1.7.10 (2014-01-06)
1125 The “weighted companion cube” release.
1127 This is a release candidate for D-Bus 1.8.
1129 D-Bus Specification 0.23:
1131 • don't require messages with no INTERFACE to be dispatched
1132 (fd.o #68597, Simon McVittie)
1134 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
1137 • define "listenable" and "connectable" addresses, and discuss
1138 the difference (fd.o #61303, Simon McVittie)
1142 • support printing Unix file descriptors in dbus-send, dbus-monitor
1143 (fd.o #70592, Robert Ancell)
1145 • don't install systemd units if --disable-systemd is given
1146 (fd.o #71818, Chengwei Yang)
1150 • don't leak memory on out-of-memory while listing activatable or
1151 active services (fd.o #71526, Radoslaw Pajak)
1153 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
1155 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
1157 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
1158 and DBUS__SEND_MSG are numerically equal to their values in the
1159 reference policy (fd.o #88719, osmond sun)
1161 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
1162 (fd.o #71366, Matt Fischer)
1164 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
1165 winsock2.h (fd.o #71405, Matt Fischer)
1167 • do not return failure from _dbus_read_nonce() with no error set,
1168 preventing a potential crash (fd.o #72298, Chengwei Yang)
1170 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
1171 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
1173 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
1174 which doesn't do anything anyway on at least Linux and FreeBSD
1175 (fd.o #69492, Simon McVittie)
1177 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
1178 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
1179 for credentials more correctly (fd.o #69492, Simon McVittie)
1181 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
1182 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
1185 • refresh cached policy rules for existing connections when bus
1186 configuration changes (fd.o #39463, Chengwei Yang)
1188 D-Bus 1.7.8 (2013-11-01)
1191 The “extreme hills” release.
1195 • If systemd support is enabled, libsystemd-journal is now required.
1199 • When activating a non-systemd service under systemd, annotate its
1200 stdout/stderr with its bus name in the Journal. Known limitation:
1201 because the socket is opened before forking, the process will still be
1202 logged as if it had dbus-daemon's process ID and user ID.
1203 (fd.o #68559, Chengwei Yang)
1205 • Document more configuration elements in dbus-daemon(1)
1206 (fd.o #69125, Chengwei Yang)
1210 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
1211 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
1213 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
1214 disallowed method calls to the audit log, fixing a regression in 1.7.6
1215 (fd.o #49062, Colin Walters)
1217 • path_namespace='/' in match rules incorrectly matched nothing; it
1218 now matches everything. (fd.o #70799, Simon McVittie)
1220 D-Bus 1.7.6 (2013-10-09)
1223 The “CSI Shrewsbury” release.
1225 Build-time configuration changes:
1227 • Directory change notification via dnotify on Linux is no longer
1228 supported; it hadn't compiled successfully since 2010 in any case.
1229 If you don't have inotify (Linux) or kqueue (*BSD), you will need
1230 to send SIGHUP to the dbus-daemon when its configuration changes.
1231 (fd.o #33001, Chengwei Yang)
1233 • Compiling with --disable-userdb-cache is no longer supported;
1234 it didn't work since at least 2008, and would lead to an extremely
1235 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
1238 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
1239 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
1240 with the Autotools build system. (fd.o #66142, Chengwei Yang)
1242 • --with-valgrind=auto enables Valgrind instrumentation if and only if
1243 valgrind headers are available. The default is still --with-valgrind=no.
1244 (fd.o #56925, Simon McVittie)
1248 • Platforms with no 64-bit integer type are no longer supported.
1249 (fd.o #65429, Simon McVittie)
1251 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
1253 • Full test coverage no longer requires dbus-glib, although the tests do not
1254 exercise the shared library (only a static copy) if dbus-glib is missing.
1255 (fd.o #68852, Simon McVittie)
1259 • D-Bus Specification 0.22
1260 · Document GetAdtAuditSessionData() and
1261 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
1262 · Fix example .service file (fd.o #66481, Chengwei Yang)
1263 · Don't claim D-Bus is "low-latency" (lower than what?), just
1264 give factual statements about it supporting async use
1265 (fd.o #65141, Justin Lee)
1266 · Document the contents of .service files, and the fact that
1267 system services' filenames are constrained
1268 (fd.o #66608; Simon McVittie, Chengwei Yang)
1270 • Be thread-safe by default on all platforms, even if
1271 dbus_threads_init_default() has not been called. For compatibility with
1272 older libdbus, library users should continue to call
1273 dbus_threads_init_default(): it is harmless to do so.
1274 (fd.o #54972, Simon McVittie)
1276 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
1278 • New API: dbus_setenv(), a simple wrapper around setenv().
1279 Note that this is not thread-safe. (fd.o #39196, Simon)
1281 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
1282 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
1283 (connect to a given bus, like dbus-monitor --address=ADDRESS).
1284 dbus-send --address still exists for backwards compatibility,
1285 but is no longer documented. (fd.o #48816, Andrey Mazo)
1288 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
1293 • Avoid an infinite busy-loop if a signal interrupts waitpid()
1294 (fd.o #68945, Simon McVittie)
1296 • Clean up memory for parent nodes when objects are unexported
1297 (fd.o #60176, Thomas Fitzsimmons)
1299 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
1300 documented. Previously, it assumed its second parameter was TRUE.
1301 (fd.o #69165, Chengwei Yang)
1303 • Escape addresses containing non-ASCII characters correctly
1304 (fd.o #53499, Chengwei Yang)
1306 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
1308 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
1309 (fd.o #65923, Chengwei Yang)
1311 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
1312 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
1314 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
1315 that was never va_start()ed (fd.o #66300, Chengwei Yang)
1317 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
1319 • fix a regression test on platforms with strict alignment (fd.o #67279,
1322 • Avoid calling function parameters "interface" since certain Windows headers
1323 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
1325 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
1327 • Various thread-safety improvements to static variables (fd.o #68610,
1330 • Make "make -j check" work (fd.o #68852, Simon McVittie)
1332 • Fix a NULL pointer dereference on an unlikely error path
1333 (fd.o #69327, Sviatoslav Chagaev)
1335 • Improve valgrind memory pool tracking (fd.o #69326,
1338 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
1341 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
1342 (fd.o #66107, Chengwei Yang)
1345 · If accept4() fails with EINVAL, as it can on older Linux kernels
1346 with newer glibc, try accept() instead of going into a busy-loop.
1347 (fd.o #69026, Chengwei Yang)
1348 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
1349 for instance on Hurd or older Linux with a new glibc, try without

1356 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
1357 · Use dbus-launch from the builddir for testing, not the installed copy
1358 (fd.o #37849, Chengwei Yang)
1359 · Fix compilation if writev() is unavailable (fd.o #69409,
1361 · Remove broken support for LOCAL_CREDS credentials passing, and
1362 document where each credential-passing scheme is used (fd.o #60340,

1388 Chengwei Yang, Vasiliy Balyasnyy)
1390 D-Bus 1.7.4 (2013-06-13)
1393 The “but is your thread-safety thread-safe?” release.
1397 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
1398 of service for system services. Vulnerability reported by Alexandru Cornea.
1403 • The Windows version of libdbus now contains a C++ source file, used
1404 to provide global initialization when the library is loaded.
1405 gcc (mingw*) users should ensure that g++ is also installed.
1407 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
1408 and was never the recommended option) has been removed. Expat is now a
1413 • It should now be safe to call dbus_threads_init_default() from any thread,
1414 at any time. Authors of loadable modules and plugins that use libdbus
1415 should consider doing so during initialization.
1416 (fd.o #54972, Simon McVittie)
1418 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
1422 · dbus-run-session: experimental new tool to start a temporary D-Bus
1423 session, e.g. for regression tests or a text console, replacing
1424 certain uses of dbus-launch which weren't really correct
1425 (fd.o #39196, Simon)
1429 • In dbus-daemon, don't crash if a .service file starts with key=value
1430 (fd.o #60853, Chengwei Yang)
1433 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
1434 on a platform not defining LOG_PERROR, such as Solaris or QNX.
1435 This regressed in 1.7.0. (Simon)
1436 · Fix an assertion failure if we try to activate systemd services before
1437 systemd connects to the bus (fd.o #50199, Chengwei Yang)
1438 · Avoid compiler warnings for ignoring the return from write()
1442 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
1443 so that Windows finds them (fd.o #59733, Ralf Habacker)
1445 D-Bus 1.7.2 (2013-04-25)
1448 The “only partially opaque” release.
1450 Configuration changes:
1452 • On non-QNX Unix platforms, the default limit on fds per message in the
1453 session bus configuration has reduced from 4096 to 1024. The default
1454 limit used on the system bus was already 1024. On QNX, both limits are
1455 reduced further, to 128.
1459 • D-Bus Specification 0.21
1460 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
1461 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
1466 • Diagnose incorrect use of dbus_connection_get_data() with negative slot

1500 remains the recommended version for long-term-supported distributions
1501 or the upcoming GNOME 3.8 release.
1503 Build-time configuration changes:
1505 • The --with-dbus-session-bus-default-address configure option is no longer
1506 supported. Use the new --with-dbus-session-bus-connect-address and
1507 --with-dbus-session-bus-listen-address options instead. On Windows, you
1508 usually want them to have the same argument; on Unix, the defaults are
1511 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
1512 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
1513 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
1515 • cmake/cross-compile.sh has been removed. Instead, please use a
1516 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
1517 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
1518 as documented in "info automake Cross-Compilation", and set
1519 PKG_CONFIG_PATH appropriately.
1523 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
1524 • man2html is no longer used.

1529 · actually say that /org/freedesktop/DBus is the object that
1530 implements o.fd.DBus (fd.o #51865, Colin Walters)
1531 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
1532 · stop claiming that all basic types work just like INT32 (strings don't!)

1535 the outdated duplicate copies used when building with CMake.
1536 (fd.o #59805; Ralf Habacker, Simon McVittie)
1540 • In the activation helper, when compiled for tests, do not reset the system
1541 bus address, fixing the regression tests. (fd.o #52202, Simon)
1543 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
1544 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
1546 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

1565 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
1568 · The default session bus listening and connecting address is now
1569 "autolaunch:", which makes D-Bus on Windows interoperate with itself
1570 and GDBus "out of the box". Use the configure options and cmake variables
1571 described above if you require a different autolaunch scope.
1572 (fd.o #38201, Simon McVittie)
1573 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)

1583 • Follow up to CVE-2012-3524: The additional hardening
1584 work to use __secure_getenv() as a followup to bug #52202
1585 broke certain configurations of gnome-keyring. Given
1586 the difficulty of making this work without extensive
1587 changes to gnome-keyring, use of __secure_getenv() is

1629 (fd.o #51032, Simon McVittie)
1631 • Disconnect "developer mode" (assertions, verbose mode etc.) from
1632 Automake maintainer mode. D-Bus developers should now configure with
1633 --enable-developer. Automake maintainer mode is now on by default;
1634 distributions can disable it with --disable-maintainer-mode.
1635 (fd.o #34671, Simon McVittie)
1637 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
1638 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)

1748 • Allow all configured auth mechanisms, not just one (fd.o #45106,
1751 • Improve cmake build system (Ralf Habacker):
1752 · simplify XML parser dependencies (fd.o #41027)
1753 · generate build timestamp (fd.o #41029)
1754 · only create batch files on Windows
1755 · fix option and cache syntax
1756 · add help-options target
1757 · share dbus-arch-deps.h.in with autotools rather than having our
1758 own version (fd.o #41033)
1760 • Build tests successfully with older GLib, as found in e.g. Debian 6
1761 (fd.o #41219, Simon McVittie)
1763 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
1765 • Build documentation correctly if man2html doesn't support filenames on
1766 its command-line (fd.o #43875, Jack Nagel)
1768 • Improve test coverage. To get even more coverage, run the tests with
1769 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
1771 • Reduce the size of the shared library by moving functionality only used
1772 by dbus-daemon, tests etc. into their internal library and deleting
1773 unused code (fd.o #34976, #39759; Simon McVittie)
1775 • Add dbus-daemon --nopidfile option, overriding the configuration, for
1776 setups where the default configuration must include <pidfile/> to avoid
1777 breaking traditional init, but the pid file is in fact unnecessary; use
1778 it under systemd to improve startup time a bit (fd.o #45520,
1781 • Optionally (if configured --with-valgrind) add instrumentation to debug
1782 libdbus and associated tools more meaningfully under Valgrind
1783 (fd.o #37286, Simon McVittie)
1785 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
1787 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
1789 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
1790 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
1791 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
1794 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
1798 · Replace our broken reimplementation of recursive mutexes, which has
1799 been broken since 2006, with an ordinary pthreads recursive mutex
1800 (fd.o #43744; Sigmund Augdal, Simon McVittie)
1801 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
1802 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
1803 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
1804 · When running under systemd, use it instead of ConsoleKit to check
1805 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
1806 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
1807 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
1808 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
1809 (fd.o #41218, Simon McVittie)
1810 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
1811 helper doesn't obey environment variables to avoid privilege escalation
1812 attacks, so make the system bus follow the same rules
1813 (fd.o #21620, Simon McVittie)
1816 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
1817 Jesper Dam, Ralf Habacker)
1818 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
1821 D-Bus 1.5.8 (2011-09-21)
1824 The "cross-metering" release.
1826 In addition to dead code removal and refactoring, this release contains all
1827 of the bugfixes from 1.4.16.
1829 • Clean up dead code, and make more warnings fatal in development builds
1830 (fd.o #39231, fd.o #41012; Simon McVittie)
1832 • If full test coverage is requested via --enable-tests, strictly require
1833 Python, pygobject and dbus-python, which are required by some tests; if not,
1834 and Python is missing, skip those tests rather than failing
1835 (fd.o #37847, Simon McVittie)
1837 • When using cmake, provide the same version-info API in the installed headers
1838 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
1840 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
1842 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
1844 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
1847 • Fix duplicates in authors list (Ralf Habacker)
1849 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
1850 (fd.o #39879, Chris Mayo)
1852 • Fix a small memory leak, and a failure to report errors, when updating
1853 a service file entry for activation (fd.o #39230, Simon McVittie)
1856 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
1857 Brian Cameron, Simon McVittie)
1858 · On systems that use libcap-ng but not systemd, drop supplemental groups
1859 when switching to the daemon user (Red Hat #726953, Steve Grubb)
1860 · Make the cmake build work again on GNU platforms (fd.o #29228,
1862 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
1863 like Solaris (fd.o #40313, Dagobert Michelsen)
1864 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
1865 (fd.o #40235, Simon McVittie)
1866 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
1867 (fd.o #39987, Simon McVittie)
1868 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
1869 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
1872 · Fix compilation on MSVC, which doesn't understand "inline" with its
1873 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
1874 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
1875 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
1877 D-Bus 1.5.6 (2011-07-29)
1880 The "weird, gravy-like aftertaste" release.
1882 In addition to new features and refactoring, this release contains all of the
1883 bugfixes from 1.4.14.
1885 Potentially incompatible (Bustle and similar debugging tools will need
1886 changes to work as intended):
1888 • Do not allow match rules to "eavesdrop" (receive messages intended for a
1889 different recipient) by mistake: eavesdroppers must now opt-in to this
1890 behaviour by putting "eavesdrop='true'" in the match rule, which will
1891 not have any practical effect on buses where eavesdropping is not allowed
1892 (fd.o #37890, Cosimo Alfarano)
1896 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
1897 Cosimo Alfarano, Simon McVittie)
1898 · add the "eavesdrop" keyword to match rules
1899 · define eavesdropping, unicast messages and broadcast messages
1900 · stop claiming that match rules are needed to match unicast messages to you
1901 · promote the type system to be a top-level section
1903 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
1904 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
1905 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
1907 • Consistently use atomic operations on everything that is ever manipulated
1908 via atomic ops, as was done for changes to DBusConnection's refcount in
1909 1.4.12 (fd.o #38005, Simon McVittie)
1911 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
1914 • Make "make check" in a clean tree work, by not running tests until
1915 test data has been set up (fd.o #34405, Simon McVittie)
1917 • The dbus-daemon no longer busy-loops if it has a very large number of file
1918 descriptors (fd.o #23194, Simon McVittie)
1920 • Refactor message flow through dispatching to avoid locking violations if
1921 the bus daemon's message limit is hit; remove the per-connection link cache,
1922 which was meant to improve performance, but now reduces it (fd.o #34393,
1925 • Some cmake fixes (Ralf Habacker)
1927 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
1928 Simon McVittie, Lennart Poettering)
1930 • Stop storing two extra byte order indicators in each D-Bus message
1931 (fd.o #38287, Simon McVittie)
1933 • Add an optional Stats interface which can be used to get statistics from
1934 a running dbus-daemon if enabled at configure time with --enable-stats
1935 (fd.o #34040, Simon McVittie)
1937 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
1939 • Documentation (fd.o #36156, Simon McVittie):
1940 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
1941 · install more documentation automatically, including man2html output
1942 · put dbus.devhelp in the right place (it must go in ${htmldir})
1945 · look for system services in /lib/dbus-1/system-services in addition to all
1946 the other well-known locations; note that this should always be /lib,
1947 even on platforms where shared libraries on the root FS would go in /lib64,
1948 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
1949 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
1951 • Windows-specific (Ralf Habacker):
1952 · fix use of a mutex for autolaunch server detection
1953 · don't crash on malloc failure in _dbus_printf_string_upper_bound
1955 D-Bus 1.5.4 (2011-06-10)
1958 Security (local denial of service):
1960 • Byte-swap foreign-endian messages correctly, preventing a long-standing
1961 local DoS if foreign-endian messages are relayed through the dbus-daemon
1962 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
1963 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
1967 • The constant to use for an infinite timeout now has a name,
1968 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
1969 which can be used for source compatibility with older versions of libdbus.
1971 • If GLib and DBus-GLib are already installed, more tests will be built,
1972 providing better coverage. The new tests can also be installed via
1973 ./configure --enable-installed-tests
1974 for system integration testing, if required. (fd.o #34570, Simon McVittie)
1978 • Consistently use atomic operations for the DBusConnection's refcount,
1979 fixing potential threading problems (fd.o #38005, Simon McVittie)
1981 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
1982 small (300KiB on x86-64) and it frequently doesn't work in unusual
1983 toolchains. To optimize for minimum installed size, you should benchmark
1984 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
1985 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
1987 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
1988 (fd.o #35880, Timothy Redaelli)
1990 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
1991 when not using a DESTDIR (fd.o #37870, Simon McVittie)
1993 • Windows-specific changes:
1994 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
1996 D-Bus 1.5.2 (2011-06-01)
1999 The "Boar Hunter" release.
2001 Notes for distributors:
2003 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2004 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2005 toolchain supports it reliably, via something like:
2007 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2009 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2013 • D-Bus Specification v0.17
2014 · Reserve the extra characters used in signatures by GVariant
2015 (fd.o #34529, Simon McVittie)
2016 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2017 • Don't force -fPIE: distributions and libtool know better than we do whether
2018 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2019 • Allow --disable-gc-sections, in case your toolchain offers the
2020 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2021 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2022 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2023 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2024 • Ensure that maintainers upload documentation with the right permissions
2025 (fd.o #36130, Simon McVittie)

2030 • Log messages dropped due to quotas to syslog (fd.o #35358,
2032 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
2033 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
2034 (fd.o #35228, Lennart Poettering)
2035 • In the regression tests, don't report fds as "leaked" if they were open
2036 on startup (fd.o #35173, Simon McVittie)
2037 • Make dbus-monitor bail out if asked to monitor more than one bus,
2038 rather than silently using the last one (fd.o #26548, Will Thompson)
2039 • Clarify documentation (fd.o #35182, Simon McVittie)
2040 • Clean up minor dead code and some incorrect error handling

2045 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
2047 D-Bus 1.5.0 (2011-04-11)
2050 The "you never know when you need to tow something from your giant
2051 flying shark" release.
2053 • D-Bus Specification v0.16
2054 · Add support for path_namespace and arg0namespace in match rules
2055 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
2056 · Make argNpath support object paths, not just object-path-like strings,
2057 and document it better (fd.o #31818, Will Thompson)
2058 • Let the bus daemon implement more than one interface (fd.o #33757,
2060 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2062 • Require user intervention to compile with missing 64-bit support
2063 (fd.o #35114, Simon McVittie)
2064 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
2065 • Raise UnknownObject instead of UnknownMethod for calls to methods on
2066 paths that are not part of the object tree, and UnknownInterface for calls
2067 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
2069 D-Bus 1.4.8 (2011-04-08)
2072 The "It's like the beginning of a lobster" release.
2074 • Rename configure.in to configure.ac, and update it to modern conventions
2075 (fd.o #32245; Javier Jardón, Simon McVittie)
2076 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
2078 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
2079 --disable-x11-autolaunch configure option to prevent it altogether
2080 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
2081 • Install the documentation, and an index for Devhelp (fd.o #13495,
2082 Debian #454142; Simon McVittie, Matthias Clasen)
2083 • If checks are not disabled, check validity of string-like types and
2084 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
2085 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
2086 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
2087 • Break up a huge conditional in config-parser so gcov can produce coverage
2088 data (fd.o #10887, Simon McVittie)
2089 • List which parts of the Desktop Entry specification are applicable to
2090 .service files (fd.o #19159, Sven Herzberg)

2102 The "1, 2, miss a few, 99, 100" release.
2104 • Remove unfinished changes intended to support GTest-based tests,
2105 which were mistakenly included in 1.4.4
2107 D-Bus 1.4.4 (2010-02-17)
2110 • Switch back to using even micro versions for stable releases; 1.4.1
2111 should have been called 1.4.2, so skip that version number
2112 • Don't leave bad file descriptors being watched when spawning processes,
2113 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
2114 also LP#656134, LP#680444, LP#713157)
2115 • Check for MSG_NOSIGNAL correctly
2116 • Fix failure to detect abstract socket support (fd.o #29895)
2117 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
2118 (fd.o #32262, NB#180486)
2119 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,

2148 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
2149 crash the bus. The existing restriction to 64-levels of nesting previously
2150 only applied to the static type signature; now it also applies to dynamic
2151 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
2153 • OS X portability fixes, including launchd support.
2154 • Windows autolaunch improvements.
2155 • Various bug fixes.
