1 D-Bus 1.10.22 (UNRELEASED)
6 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
7 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
9 • dbus_message_iter_open_container() no longer leaks memory if it runs out
10 of memory. (fd.o #101568, Simon McVittie)
12 • dbus_message_append_args_valist() no longer leaks memory if given an
13 unsupported type. This situation is still considered to be a programming
14 error which needs to be corrected by the user of libdbus.
15 (fd.o #101568, Simon McVittie)
17 • Wrap test-pending-call-disconnected with dbus-run-session so that it can
18 pass in environments that are not already running a D-Bus session bus,
19 fixing a build-time test regression in 1.10.20
20 (fd.o #101698, Simon McVittie)
22 D-Bus 1.10.20 (2017-06-29)
25 The “suggesting a delivery gone horribly wrong” release.
29 • Fix a reference leak when blocking on a pending call on a connection
30 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
32 • Don't put timestamps in the Doxygen-generated documentation, for
33 closer-to-reproducible builds (fd.o #100692, Simon McVittie)
35 • Avoid an assertion failure when connecting to a semicolon-separated
36 series of addresses, one of which fails (fd.o #101257, Simon McVittie)
40 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
41 (fd.o #100715, Simon McVittie)
43 D-Bus 1.10.18 (2017-04-05)
46 The “can't handle a self-referential paradox” release.
50 • Re-order dbus-daemon startup so that on SELinux systems, the thread
51 that reads AVC notifications retains the ability to write to the
52 audit log (fd.o #92832, Debian #857660; Laurent Bigonville)
54 • Fix a harmless read overflow and some memory leaks in a unit test
55 (fd.o #100568, Philip Withnall)
57 D-Bus 1.10.16 (2017-02-16)
60 The “super digging powers” release.
62 The fixes in this release are arguably security fixes, but if they
63 affect you, please take this opportunity to rethink how you are
68 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
69 stable and Debian testing in addition to the older Ubuntu that is
70 the default (fd.o #98889, Simon McVittie)
74 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
75 allow an attacker to overwrite a file named "nonce", in a directory
76 that the user running dbus-daemon can write, with a random value
77 known only to the user running dbus-daemon. This is unlikely to be
78 exploitable in practice, particularly since the nonce-tcp transport
79 is really only useful on Windows.
81 On Unix systems we strongly recommend using only the unix: and systemd:
82 transports, together with EXTERNAL authentication. These are the only
83 transports and authentication mechanisms enabled by default.
85 (fd.o #99828, Simon McVittie)
87 • Avoid symlink attacks in the "embedded tests", which are not enabled
88 by default and should never be enabled in production builds of dbus.
89 (fd.o #99828, Simon McVittie)
91 D-Bus 1.10.14 (2016-11-28)
94 The “Well, other bands know more than three chords” release.
98 • Work around an undesired effect of the fix for CVE-2014-3637
99 (fd.o #80559), in which processes that frequently send fds, such as
100 logind during a flood of new PAM sessions, can get disconnected for
101 continuously having at least one fd "in flight" for too long;
102 dbus-daemon interprets that as a potential denial of service attack.
103 The workaround is to disable that check for uid 0 process such as
104 logind, with a message in the system log. The bug remains open while
105 we look for a more general solution.
106 (fd.o #95263, LP#1591411; Simon McVittie)
108 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
109 was disabled at compile time. That test is not expected to work
110 in that configuration. (fd.o #98665, Simon McVittie)
112 D-Bus 1.10.12 (2016-10-10)
115 The “not excessively inhospitable” release.
119 • Do not treat ActivationFailure message received from root-owned systemd
120 name as a format string. In principle this is a security vulnerability,
121 but we do not believe it is exploitable in practice, because only
122 privileged processes can own the org.freedesktop.systemd1 bus name, and
123 systemd does not appear to send activation failures that contain "%".
125 Please note that this probably *was* exploitable in dbus versions
126 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
127 the time was only thought to be a denial of service vulnerability
128 (CVE-2015-0245). If you are still running one of those versions,
129 patch or upgrade immediately.
131 (fd.o #98157, Simon McVittie)
135 • Harden dbus-daemon against malicious or incorrect ActivationFailure
136 messages by rejecting them if they do not come from a privileged
137 process, or if systemd activation is not enabled
138 (fd.o #98157, Simon McVittie)
140 • Avoid undefined behaviour when setting reply serial number without going
141 via union DBusBasicValue (fd.o #98035, Marc Mutz)
143 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
145 D-Bus 1.10.10 (2016-08-15)
148 The “tungsten door” release.
152 • On Linux, when dbus-daemon is run with reduced susceptibility to the
153 OOM killer (typically via systemd), do not let child processes inherit
154 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
156 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
157 contains a semicolon (fd.o #94746, Thiago Macieira)
159 • Fix memory leaks and thread safety in subprocess starting on Windows
160 (fd.o #95191, Ralf Habacker)
162 • Do not require systemd to have a service file if using it for activation
163 (fd.o #93194; Simon McVittie; backport from 1.11.0)
165 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
166 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
168 • In tests that exercise correct handling of crashing D-Bus services,
169 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
171 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
173 • update-activation-environment: produce better diagnostics on error
174 (fd.o #96653, Simon McVittie)
176 • Don't fail the build with an unused const variable warning under gcc 6
177 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
179 • Merge dbus-1.10-ci branch, containing backports from 1.11.0 in build/test
180 code to support continuous integration (fd.o #93194, Simon McVittie)
182 · Avoid -Wunused-label when compiling with libselinux but no libaudit
183 · In development builds, allow OOM tests to be disabled as documented
184 · Accept and ignore the --tap argument in all "embedded tests", and run
185 all automated tests with that argument for better diagnostics
186 · Fix the systemd activation test under CMake by installing the required
188 · In Automake, fix shell syntax for installcheck-local with no DESTDIR
189 · In Automake, don't try to run manual tests in installcheck
190 · In CMake, don't run manual-tcp test as an automated test
191 · Add travis-ci.org build machinery
193 D-Bus 1.10.8 (2016-03-07)
196 The “digestive biscuits” release.
200 • Enable "large file support" on systems where it exists: dbus-daemon
201 is not expected to open large files, but it might need to stat files
202 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
204 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
205 which might result in a pedantic C compiler not copying the entire contents
206 of a DBusMessageIter; statically assert that this is not an ABI change
207 in practice (fd.o #94136, Simon McVittie)
209 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
210 (fd.o #94244, Dmitri Iouchtchenko)
212 • Correctly report test failures in C tests from run-test.sh
213 (fd.o #93379; amit tewari, Simon McVittie)
215 • When tests are enabled, run all the marshal-validate tests, not just
216 the even-numbered ones (fd.o #93908, Nick Lewycky)
218 • Correct the expected error from one marshal-validate test, which was
219 previously not run due to the above bug (fd.o #93908, Simon McVittie)
221 D-Bus 1.10.6 (2015-12-01)
224 The “marzipan beetles” release.
228 • On Unix when running tests as root, don't assert that root and
229 the dbus-daemon user can still call UpdateActivationEnvironment;
230 assert that those privileged users can call BecomeMonitor instead
231 (fd.o #93036, Simon McVittie)
233 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
236 • On Windows Autotools builds, don't run tests that rely on
237 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
239 D-Bus 1.10.4 (2015-11-17)
242 The “Frostburn Canyon” release.
246 • GetConnectionCredentials, GetConnectionUnixUser and
247 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
248 will now return details of the dbus-daemon itself. This is required
249 to be able to call SetEnvironment on systemd.
250 (fd.o #92857, Jan Alexander Steffens)
254 • Make UpdateActivationEnvironment always fail with AccessDenied on the
255 system bus. Previously, it was possible to configure it so root could
256 call it, but the environment variables were not actually used,
257 because the launch helper would discard them.
258 (fd.o #92857, Jan Alexander Steffens)
260 • On Unix with --systemd-activation on a user bus, make
261 UpdateActivationEnvironment pass on its arguments to systemd's
262 SetEnvironment method, solving inconsistency between the environments
263 used for traditional activation and systemd user-service activation.
264 (fd.o #92857, Jan Alexander Steffens)
266 • On Windows, don't crash if <syslog/> or --syslog is used
267 (fd.o #92538, Ralf Habacker)
269 • On Windows, fix a memory leak when setting a DBusError from a Windows
270 error (fd.o #92721, Ralf Habacker)
272 • On Windows, don't go into infinite recursion if we abort the process
273 with backtraces enabled (fd.o #92721, Ralf Habacker)
275 • Fix various failing tests, variously on Windows and cross-platform:
276 · don't test system.conf features (users, groups) that only make sense
277 on the system bus, which is not supported on Windows
278 · don't call _dbus_warn() when we skip a test, since it is fatal
279 · fix computation of expected <standard_session_servicedirs/>
280 · when running TAP tests, translate newlines to Unix format, fixing
281 cross-compiled tests under Wine on Linux
282 · don't stress-test refcounting under Wine, where it's really slow
283 · stop assuming that a message looped-back to the test will be received
285 · skip some system bus tests on Windows since they make no sense there
286 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
288 D-Bus 1.10.2 (2015-10-26)
291 The “worst pies in London” release.
295 • Correct error handling for activation: if there are multiple attempts
296 to activate the same service and it fails immediately, the first attempt
297 would get the correct reply, but the rest would time out. We now send
298 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
300 • If BecomeMonitor is called with a syntactically invalid match rule,
301 don't crash with an assertion failure, fixing a regression in 1.9.10.
302 This was not exploitable as a denial of service, because the check
303 for a privileged user is done first. (fd.o #92298, Simon McVittie)
305 • On Linux with --enable-user-session, add the bus address to the
306 environment of systemd services for better backwards compatibility
307 (fd.o #92612, Jan Alexander Steffens)
309 • On Windows, fix the logic for replacing the installation prefix
310 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
312 • On Windows, if installed in the conventional layout with ${prefix}/etc
313 and ${prefix}/share, use relative paths between bus configuration files
314 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
316 • Make more of the regression tests pass in Windows builds (fd.o #92538,
319 D-Bus 1.10.0 (2015-08-25)
324 This is a new stable branch, recommended for use in OS distributions.
328 • distribute test/tap-test.sh.in, even if the tarball was built without
329 tests enabled (fd.o #91684, Simon McVittie)
330 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
332 Summary of major changes since 1.8.0:
334 • The basic setup for the well-known system and session buses is
335 now done in read-only files in ${datadir} (normally /usr/share).
336 See the NEWS entry for 1.9.18 for details.
338 • AppArmor integration has been merged, with features similar to the
339 pre-existing SELinux integration. It is mostly compatible with the
340 patches previously shipped by Ubuntu, with one significant change:
341 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
342 by GetConnectionCredentials and was not included.
344 • The --enable-user-session configure option can be enabled
345 by OS integrators intending to use systemd to provide a session bus
346 per user (in effect, treating all concurrent graphical and non-graphical
347 login sessions as one large session).
349 • The new listenable address mode "unix:runtime=yes" listens on
350 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
351 user session. libdbus and "dbus-launch --autolaunch" will connect to
352 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
355 • All executables are now dynamically linked to libdbus-1.
356 Previously, some executables, most notably dbus-daemon, were statically
357 linked to a specially-compiled variant of libdbus. This results in
358 various private functions in the _dbus namespace being exposed by the
359 shared library. These are not API, and must not be used outside
360 the dbus source tree.
362 • On platforms with ELF symbol versioning, all public symbols
363 are versioned LIBDBUS_1_3.
367 • org.freedesktop.DBus.GetConnectionCredentials returns
368 LinuxSecurityLabel where supported
369 • org.freedesktop.DBus.Monitoring interface (privileged)
370 · BecomeMonitor method supersedes match rules with eavesdrop=true,
371 which are now deprecated
372 • org.freedesktop.DBus.Stats interface (semi-privileged)
373 · now enabled by default
374 · new GetAllMatchRules method
375 • org.freedesktop.DBus.Verbose interface (not normally compiled)
376 · toggles the effect of DBUS_VERBOSE
381 • dbus-update-activation-environment
383 New optional dependencies:
385 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
386 • Complete documentation requires Ducktype and yelp-tools
387 • Full test coverage requires GLib 2.36 and PyGI
388 • AppArmor integration requires libapparmor and optionally libaudit
390 Dependencies removed:
394 D-Bus 1.9.20 (2015-08-06)
397 The “Remember Tomorrow” release.
399 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
404 • Don't second-guess what the ABI of poll() is, allowing it to be used
405 on Integrity RTOS and other unusual platforms (fd.o #90314;
406 Rolland Dudemaine, Simon McVittie)
408 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
409 both enabled (fd.o #89225, Simon McVittie)
411 • Log audit events for AppArmor/SELinux policy violations whenever
412 we have CAP_AUDIT_WRITE, even if not the system bus
413 (fd.o #83856, Laurent Bigonville)
415 D-Bus 1.9.18 (2015-07-21)
418 The “Pirate Elite” release.
420 Configuration changes:
422 • The basic setup for the well-known system and session buses is now done
423 in read-only files in ${datadir}, moving a step closer to systems
424 that can operate with an empty /etc directory. In increasing order
427 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
428 the default message policies.
429 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
430 dbus still installs a trivial version of each, for documentation
431 purposes; putting configuration directives in these files is deprecated.
432 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
433 to install "drop-in" configuration snippets (any packages
434 using those directories should explicitly depend on at least this
436 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
437 or third-party software to install "drop-in" configuration snippets
438 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
441 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
442 and "s*" refers to either system or session as appropriate.
444 (fd.o #89280, Dimitri John Ledkov)
448 • Fix a memory leak when GetConnectionCredentials() succeeds
449 (fd.o #91008, Jacek Bukarewicz)
451 • Ensure that dbus-monitor does not reply to messages intended for others,
452 resulting in its own disconnection (fd.o #90952, Simon McVittie)
454 D-Bus 1.9.16 (2015-05-14)
457 The “titanium barns” release.
461 • Automake 1.13 is now required when compiling from git or modifying
466 • On Unix platforms, change the default configuration for the session bus
467 to only allow EXTERNAL authentication (secure kernel-mediated
468 credentials-passing), as was already done for the system bus.
470 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
471 unpredictable pseudo-random numbers.
473 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
474 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
475 NFS or similar, you will need to reconfigure the session bus to accept
476 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
479 (fd.o #90414, Simon McVittie)
481 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
482 transport, UUIDs or any other reason, fail if we cannot obtain entropy
483 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
484 occurs, instead of silently falling back to low-entropy pseudorandom
485 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
489 • Add dbus_message_iter_get_element_count()
490 (fd.o #30350; Christian Dywan, Simon McVittie)
492 • Introduce new internal DBusSocket and DBusPollable types so we can
493 stop treating the Windows SOCKET type as if it was int. DBusSocket
494 is specifically a socket, cross-platform. DBusPollable is whatever
495 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
496 (fd.o #89444; Ralf Habacker, Simon McVittie)
498 • All regression tests now output TAP <https://testanything.org/>
499 (fd.o #89846, Simon McVittie)
501 • Internal APIs consistently use signed values for timestamps
502 (fd.o #18494, Peter McCurdy)
504 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
505 (fd.o #88812, Simon McVittie)
507 • Clean up a lot of compiler warnings
508 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
512 • Add locking to DBusCounter's reference count and notify function
513 (fd.o #89297, Adrian Szyndela)
515 • Ensure that DBusTransport's reference count is protected by the
516 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
518 • Correctly release DBusServer mutex before early-return if we run out
519 of memory while copying authentication mechanisms (fd.o #90021,
522 • Make dbus-test-tool and dbus-update-activation-environment portable
523 to Windows (fd.o #90089, Ralf Habacker)
525 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
526 Ralf Habacker, Simon McVittie)
528 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
531 • Clean up some memory and fd leaks in test code and tools
532 (fd.o #90021, Ralf Habacker)
534 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
535 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
537 • CMake generates a versioned shared library even if the revision is 0,
538 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
540 D-Bus 1.9.14 (2015-03-02)
543 The “don't stand in the poison cloud” release.
547 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
548 were previously linked to a static version of libdbus.
550 • The tests no longer require dbus-glib in order to exercise the libdbus
551 shared library; they are always linked to libdbus now.
553 Build-time configuration:
555 • The new --enable-user-session option, off by default, can be enabled
556 by OS integrators intending to use systemd to provide a session bus
557 per user (in effect, treating all concurrent graphical and non-graphical
558 login sessions as one large session)
562 • All executables are now linked dynamically to libdbus.
563 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
565 • On platforms that support them (GNU libc and possibly others),
566 libdbus now has versioned symbols for its public API.
567 All public symbols (visible in the header files) are currently
568 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
569 dbus_internal have a version that changes with each release, and
570 must not be used by applications. (also fd.o #83115)
572 • New listenable address mode "unix:runtime=yes" which listens on
573 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
574 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
576 • Add optional systemd units for a per-user bus listening on
577 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
579 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
580 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
583 • New dbus-update-activation-environment tool uploads environment
584 variables to "dbus-daemon --session" and optionally "systemd --user",
585 primarily as a way to keep the per-user bus compatible with
586 distributions' existing X11 login scripts (also fd.o #61301)
588 • <includedir/> elements in dbus-daemon configuration are now silently
589 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
591 • Add microsecond-resolution timestamps to the default output of
592 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
596 • Fix a race condition in the 'monitor' test introduced in 1.9.10
597 (fd.o #89222, Simon McVittie)
599 D-Bus 1.9.12 (2015-02-19)
602 The “monster lasagna” release.
606 • Ducktype and yelp-tools are now required to build complete documentation
607 (they are optional for normal builds).
611 • D-Bus Specification version 0.26
612 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
613 · document the BecomeMonitor method
615 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
616 (fd.o #89041; Tyler Hicks, Simon McVittie)
618 • On Linux, add support for AppArmor mediation of message sending and
619 receiving and name ownership (paralleling existing SELinux mediation
620 support), and eavesdropping (a new check, currently AppArmor-specific)
621 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
623 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
624 that have printable ASCII contents; we previously only did this for
625 unterminated bytestrings (fd.o #89109, Simon McVittie)
627 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
629 • On Windows, add WindowsSID to GetConnectionCredentials
630 (fd.o #54445, Ralf Habacker)
632 • Improve clarity of dbus-monitor --profile output and add more columns
633 (fd.o #89165, Ralf Habacker)
635 • Add a man page for dbus-test-tool, and build it under CMake as well
636 as Autotools (fd.o#89086, Simon McVittie)
638 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
639 to control it at runtime, overriding the DBUS_VERBOSE environment variable
640 (fd.o #88896, Ralf Habacker)
644 • Reduce the number of file descriptors used in the fd-passing test,
645 avoiding failure under the default Linux fd limit, and automatically
646 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
648 D-Bus 1.9.10 (2015-02-09)
651 The “sad cyborgs” release.
653 Security fixes merged from 1.8.16:
655 • Do not allow non-uid-0 processes to send forged ActivationFailure
656 messages. On Linux systems with systemd activation, this would
657 allow a local denial of service: unprivileged processes could
658 flood the bus with these forged messages, winning the race with
659 the actual service activation and causing an error reply
660 to be sent back when service auto-activation was requested.
661 This does not prevent the real service from being started,
662 so the attack only works while the real service is not running.
663 (CVE-2015-0245, fd.o #88811; Simon McVittie)
667 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
668 similar tools receive messages without altering the security properties
669 of the system bus, by calling the new BecomeMonitor method on a
670 private connection. This bypasses the normal <allow> and <deny> rules
671 entirely, so to preserve normal message-privacy assumptions, only root
672 is allowed to do this on the system bus. Restricted environments,
673 such as Linux with LSMs, should lock down access to the Monitoring
674 interface. (fd.o #46787, Simon McVittie)
676 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
677 dbus-daemon supports it and access permissions allow it.
678 It still supports the previous approach ("eavesdropping" match rules)
679 for compatibility with older bus daemons. (fd.o #46787, Simon)
681 • dbus-monitor can now log the message stream as binary data for later
682 analysis, with either no extra framing beyond the normal D-Bus headers,
683 or libpcap-compatible framing treating each D-Bus message
684 as a captured packet. (fd.o #46787, Simon)
688 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
690 • On Unix, forcibly terminate regression tests after 60 seconds to
691 prevent them from blocking continuous integration frameworks
694 D-Bus 1.9.8 (2015-02-03)
697 The “all the types of precipitation” release.
701 • full test coverage now requires GLib 2.36
702 • full test coverage now requires PyGI (PyGObject 3,
703 "import gi.repository.GObject") instead of the
704 obsolete PyGObject 2 ("import gobject")
708 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
710 • better regression test coverage, including systemd activation
711 (fd.o #57952, #88810; Simon McVittie)
715 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
716 turned off (fd.o #88808, Simon McVittie)
718 • TCP sockets on Windows no longer fail to listen approximately 1 time
719 in 256, caused by a logic error that should have always made it fail but
720 was mitigated by incorrect endianness for the port number
721 (fd.o #87999, Ralf Habacker)
723 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
725 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
726 previous 64, completing a previous fix which only worked under
727 Autotools (fd.o #71297, Ralf Habacker)
729 • on Windows, if the IP family is unspecified only use IPv4,
730 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
732 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
734 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
736 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
739 D-Bus 1.9.6 (2015-01-05)
742 The “I do have a bread knife” release.
746 • Do not allow calls to UpdateActivationEnvironment from uids other than
747 the uid of the dbus-daemon. If a system service installs unsafe
748 security policy rules that allow arbitrary method calls
749 (such as CVE-2014-8148) then this prevents memory consumption and
750 possible privilege escalation via UpdateActivationEnvironment.
752 We believe that in practice, privilege escalation here is avoided
753 by dbus-daemon-launch-helper sanitizing its environment; but
754 it seems better to be safe.
756 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
757 on object paths other than /org/freedesktop/DBus. Some system services
758 install unsafe security policy rules that allow arbitrary method calls
759 to any destination, method and interface with a specified object path;
760 while less bad than allowing arbitrary method calls, these security
761 policies are still harmful, since dbus-daemon normally offers the
762 same API on all object paths and other system services might behave
767 • Add missing initialization so GetExtendedTcpTable doesn't crash on
768 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
770 D-Bus 1.9.4 (2014-11-24)
773 The “extra-sturdy caramel” release.
777 • Partially revert the CVE-2014-3639 patch by increasing the default
778 authentication timeout on the system bus from 5 seconds back to 30
779 seconds, since this has been reported to cause boot regressions for
780 some users, mostly with parallel boot (systemd) on slower hardware.
782 On fast systems where local users are considered particularly hostile,
783 administrators can return to the 5 second timeout (or any other value
784 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
787 <limit name="auth_timeout">5000</limit>
790 (fd.o #86431, Simon McVittie)
792 • Add a message in syslog/the Journal when the auth_timeout is exceeded
793 (fd.o #86431, Simon McVittie)
795 • Send back an AccessDenied error if the addressed recipient is not allowed
796 to receive a message (and in builds with assertions enabled, don't
797 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
799 D-Bus 1.9.2 (2014-11-10)
802 The “structurally unsound flapjack” release.
806 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
807 so that CVE-2014-3636 part A cannot exhaust the system bus'
808 file descriptors, completing the incomplete fix in 1.8.8.
809 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
813 • D-Bus Specification version 0.25
814 · new value 'const' for EmitsChangedSignal annotation
815 (fd.o #72958, Lennart Poettering)
816 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
817 (fd.o #83449; Lennart Poettering, Simon McVittie)
818 · annotate table of types with reserved/basic/container, and for
819 basic types, fixed/string-like
820 · clarify arbitrary limits by quoting them in mebibytes
822 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
823 (fd.o #83449, Simon McVittie)
825 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
826 useful for debugging and performance testing:
827 · dbus-test-tool spam: send repeated messages
828 · dbus-test-tool echo: send an empty reply for all method calls
829 · dbus-test-tool black-hole: do not reply to method calls
830 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
832 • Add support for process ID in credentials-passing on NetBSD
833 (fd.o #69702, Patrick Welche)
835 • Add an example script to find potentially undesired match rules
836 (fd.o #84598, Alban Crequy)
838 • Document the central assumption that makes our use of credentials-passing
839 secure (fd.o #83499, Simon McVittie)
841 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
842 and add some links to GDBus and QtDBus documentation (fd.o #25140,
847 • Use a less confusing NoReply message when disconnected with a reply pending
848 (fd.o #76112, Simon McVittie)
850 • Make the .pc file relocatable by letting pkg-config do all variable
851 expansion itself (fd.o #75858, Руслан Ижбулатов)
853 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
854 (fd.o #85563, Patrick Welche)
856 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
858 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
859 do not lose the exec() errno (fd.o #24821, Simon McVittie)
861 • Do not fail the tests if a parent process has leaked non-close-on-exec
862 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
864 • Do not fail the tests on Unix platforms with incomplete
865 credentials-passing support, but do fail if we can't pass credentials
866 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
867 (fd.o #69702, Simon McVittie)
869 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
870 when building with cmake, and expand test coverage there
871 (fd.o #73689; Ralf Habacker, Simon McVittie)
873 D-Bus 1.9.0 (2014-10-01)
876 The “tiered cheeses” release.
880 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
881 requires either the libsystemd or libsd-daemon shared library, dropping the
882 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
884 Build-time configuration changes:
886 • The Stats interface is now enabled by default, and locked-down to
887 root-only on the system bus. Configure with --disable-stats
888 to disable it altogether on memory- or disk-constrained systems,
889 or see ${docdir}/examples/ to open it up to non-root users on the
890 system bus or restrict access on the session bus.
891 (fd.o #80759; Simon McVittie, Alban Crequy)
893 • The CMake build system now builds the same shared library name as Autotools
894 on at least Linux and Windows:
895 - on Linux (and perhaps other Unix platforms), it previously built
896 libdbus-1.so, but now builds libdbus-1.so.3.* with development
897 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
898 - on Windows, it previously built either libdbus-1.dll (release) or
899 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
900 libdbus-1.dll for compatibility with older applications.
901 (fd.o #74117, Ralf Habacker)
905 • D-Bus Specification version 0.24
906 · document how to quote match rules (fd.o #24307, Simon McVittie)
907 · explicitly say that most message types never expect a reply
908 regardles of whether they have NO_REPLY_EXPECTED
909 (fd.o #75749, Simon McVittie)
911 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
912 initial latency (fd.o #75544, Matt Hoosier)
914 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
915 (fd.o #69702, Patrick Welche)
917 • in dbus-monitor, print more information about file descriptors
918 (fd.o #80603, Alban Crequy)
920 • do not install system bus configuration if built for Windows
921 (fd.o #83583; Ralf Habacker, Simon McVittie)
923 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
925 • Add a regression test for file descriptor passing (fd.o #83622,
930 • fix an incorrect error message if a Unix socket path is too long
931 (fd.o #73887, Antoine Jacoutot)
933 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
934 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
936 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
937 in ps(1) (fd.o #69716, Chengwei Yang)
939 • avoid calling poll() with timeout < -1, which is considered invalid
940 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
942 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
943 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
944 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
946 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
948 • Documentation improvements
949 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
951 • in dbus-monitor, do not leak file descriptors that we have monitored
952 (fd.o #80603, Alban Crequy)
954 • Set the close-on-exec flag for the inotify file descriptor, even
955 if built with CMake or older libc (fd.o #73689, Simon McVittie)
957 • Remove some LGPL code from the Windows dbus-daemon
958 (fd.o #57272, Ralf Habacker)
960 D-Bus 1.8.8 (2014-09-16)
963 The "smashy smashy egg man" release.
967 • Do not accept an extra fd in the padding of a cmsg message, which
968 could lead to a 4-byte heap buffer overrun.
969 (CVE-2014-3635, fd.o #83622; Simon McVittie)
971 • Reduce default for maximum Unix file descriptors passed per message
972 from 1024 to 16, preventing a uid with the default maximum number of
973 connections from exhausting the system bus' file descriptors under
974 Linux's default rlimit. Distributors or system administrators with a
975 more restrictive fd limit may wish to reduce these limits further.
977 Additionally, on Linux this prevents a second denial of service
978 in which the dbus-daemon can be made to exceed the maximum number
979 of fds per sendmsg() and disconnect the process that would have
981 (CVE-2014-3636, fd.o #82820; Alban Crequy)
983 • Disconnect connections that still have a fd pending unmarshalling after
984 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
985 removing the possibility of creating an abusive connection that cannot be
986 disconnected by setting up a circular reference to a connection's
988 (CVE-2014-3637, fd.o #80559; Alban Crequy)
990 • Reduce default for maximum pending replies per connection from 8192 to 128,
991 mitigating an algorithmic complexity denial-of-service attack
992 (CVE-2014-3638, fd.o #81053; Alban Crequy)
994 • Reduce default for authentication timeout on the system bus from
995 30 seconds to 5 seconds, avoiding denial of service by using up
996 all unauthenticated connection slots; and when all unauthenticated
997 connection slots are used up, make new connection attempts block
998 instead of disconnecting them.
999 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1003 • Check for libsystemd from systemd >= 209, falling back to
1004 the older separate libraries if not found (Umut Tezduyar Lindskog,
1007 • On Linux, use prctl() to disable core dumps from a test executable
1008 that deliberately raises SIGSEGV to test dbus-daemon's handling
1009 of that condition (fd.o #83772, Simon McVittie)
1011 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
1014 • Improve documentation for running tests on Windows (fd.o #41252,
1017 D-Bus 1.8.6 (2014-06-02)
1022 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1023 the message. This prevents an attack in which a malicious client can
1024 make dbus-daemon disconnect a system service, which is a local
1026 (fd.o #80163, CVE-2014-3532; Alban Crequy)
1028 • Track remaining Unix file descriptors correctly when more than one
1029 message in quick succession contains fds. This prevents another attack
1030 in which a malicious client can make dbus-daemon disconnect a system
1032 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
1033 Simon McVittie, Alban Crequy)
1037 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
1038 attach to a session, kill the dbus-daemon as intended
1039 (fd.o #74698, Роман Донченко)
1041 D-Bus 1.8.4 (2014-06-10)
1046 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1047 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1048 Additionally, in highly unusual environments the same flaw could lead to
1049 a side channel between processes that should not be able to communicate.
1050 (CVE-2014-3477, fd.o #78979)
1052 D-Bus 1.8.2 (2014-04-30)
1055 The “nobody wants red” release.
1059 • in the CMake build system, add some hints for Linux users cross-compiling
1060 Windows D-Bus binaries to be able to run tests under Wine
1061 (fd.o #41252, Ralf Habacker)
1063 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
1067 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
1068 to /var/lib/dbus/machine-id instead of generating an entirely new ID
1069 (fd.o #77941, Simon McVittie)
1071 • if dbus-launch receives an X error very quickly, do not kill
1072 unrelated processes (fd.o #74698, Роман Донченко)
1074 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
1075 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
1077 • cope with \r\n newlines in regression tests, since on Windows,
1078 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
1080 D-Bus 1.8.0 (2014-01-20)
1083 The “Wolverine distrusts my printer” release.
1085 This starts a new stable branch. The 1.6.x branch is now considered to be
1086 outdated, and will only receive fixes for serious bugs such as security
1087 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1088 are unlikely to get any more releases, but if distributors still need to
1089 support them, please share security patches via upstream.
1091 Summary of changes since 1.6.x:
1093 • libdbus always behaves as if dbus_threads_init_default() had been called
1094 (thread-safety by default)
1095 • new dbus-run-session tool, replacing certain misuses of dbus-launch
1096 • dbus-monitor can talk to outdated versions of dbus-daemon again
1097 • new org.freedesktop.DBus.GetConnectionCredentials method
1098 • GetConnectionUnixProcessID also works correctly on Windows, returning
1099 the Windows process ID
1100 • GetConnectionWindowsSID returns the correct SID on Windows
1101 • expat is required, libxml2 can no longer be used as a substitute
1102 • the userDB cache is required, and cannot be disabled
1103 • a 64-bit integer type (either int, long, long long or _int64) is required
1104 • better systemd-journald integration on Linux
1105 • fixed long-standing fd and array leaks when failing to parse a message
1106 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
1107 when using certain object-path allocation patterns, notably in Avahi
1108 • better defaults for Windows support
1109 • better CMake support
1110 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
1111 • the source language for the man pages is now Docbook XML
1113 Enhancements since 1.7.10:
1115 • Enhance the CMake build system to check for GLib and compile/run
1116 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
1120 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
1123 • fix compilation of systemd journal support on older systemd versions where
1124 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
1126 • fix compilation on older MSVC versions by including stdlib.h
1127 (fd.o #73455, Ralf Habacker)
1129 • Allow <allow_anonymous/> to appear in an included configuration file
1130 (fd.o #73475, Matt Hoosier)
1132 Test behaviour changes since 1.7.10:
1134 • If the tests crash with an assertion failure, they no longer default to
1135 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
1136 environment if you want the old behaviour.
1138 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
1139 can be run with an external dbus-daemon by setting
1140 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
1141 an unusually-configured dbus-daemon are skipped.
1143 D-Bus 1.7.10 (2014-01-06)
1146 The “weighted companion cube” release.
1148 This is a release candidate for D-Bus 1.8.
1150 D-Bus Specification 0.23:
1152 • don't require messages with no INTERFACE to be dispatched
1153 (fd.o #68597, Simon McVittie)
1155 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
1158 • define "listenable" and "connectable" addresses, and discuss
1159 the difference (fd.o #61303, Simon McVittie)
1163 • support printing Unix file descriptors in dbus-send, dbus-monitor
1164 (fd.o #70592, Robert Ancell)
1166 • don't install systemd units if --disable-systemd is given
1167 (fd.o #71818, Chengwei Yang)
1171 • don't leak memory on out-of-memory while listing activatable or
1172 active services (fd.o #71526, Radoslaw Pajak)
1174 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
1176 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
1178 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
1179 and DBUS__SEND_MSG are numerically equal to their values in the
1180 reference policy (fd.o #88719, osmond sun)
1182 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
1183 (fd.o #71366, Matt Fischer)
1185 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
1186 winsock2.h (fd.o #71405, Matt Fischer)
1188 • do not return failure from _dbus_read_nonce() with no error set,
1189 preventing a potential crash (fd.o #72298, Chengwei Yang)
1191 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
1192 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
1194 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
1195 which doesn't do anything anyway on at least Linux and FreeBSD
1196 (fd.o #69492, Simon McVittie)
1198 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
1199 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
1200 for credentials more correctly (fd.o #69492, Simon McVittie)
1202 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
1203 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
1206 • refresh cached policy rules for existing connections when bus
1207 configuration changes (fd.o #39463, Chengwei Yang)
1209 D-Bus 1.7.8 (2013-11-01)
1212 The “extreme hills” release.
1216 • If systemd support is enabled, libsystemd-journal is now required.
1220 • When activating a non-systemd service under systemd, annotate its
1221 stdout/stderr with its bus name in the Journal. Known limitation:
1222 because the socket is opened before forking, the process will still be
1223 logged as if it had dbus-daemon's process ID and user ID.
1224 (fd.o #68559, Chengwei Yang)
1226 • Document more configuration elements in dbus-daemon(1)
1227 (fd.o #69125, Chengwei Yang)
1231 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
1232 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
1234 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
1235 disallowed method calls to the audit log, fixing a regression in 1.7.6
1236 (fd.o #49062, Colin Walters)
1238 • path_namespace='/' in match rules incorrectly matched nothing; it
1239 now matches everything. (fd.o #70799, Simon McVittie)
1241 D-Bus 1.7.6 (2013-10-09)
1244 The “CSI Shrewsbury” release.
1246 Build-time configuration changes:
1248 • Directory change notification via dnotify on Linux is no longer
1249 supported; it hadn't compiled successfully since 2010 in any case.
1250 If you don't have inotify (Linux) or kqueue (*BSD), you will need
1251 to send SIGHUP to the dbus-daemon when its configuration changes.
1252 (fd.o #33001, Chengwei Yang)
1254 • Compiling with --disable-userdb-cache is no longer supported;
1255 it didn't work since at least 2008, and would lead to an extremely
1256 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
1259 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
1260 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
1261 with the Autotools build system. (fd.o #66142, Chengwei Yang)
1263 • --with-valgrind=auto enables Valgrind instrumentation if and only if
1264 valgrind headers are available. The default is still --with-valgrind=no.
1265 (fd.o #56925, Simon McVittie)
1269 • Platforms with no 64-bit integer type are no longer supported.
1270 (fd.o #65429, Simon McVittie)
1272 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
1274 • Full test coverage no longer requires dbus-glib, although the tests do not
1275 exercise the shared library (only a static copy) if dbus-glib is missing.
1276 (fd.o #68852, Simon McVittie)
1280 • D-Bus Specification 0.22
1281 · Document GetAdtAuditSessionData() and
1282 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
1283 · Fix example .service file (fd.o #66481, Chengwei Yang)
1284 · Don't claim D-Bus is "low-latency" (lower than what?), just
1285 give factual statements about it supporting async use
1286 (fd.o #65141, Justin Lee)
1287 · Document the contents of .service files, and the fact that
1288 system services' filenames are constrained
1289 (fd.o #66608; Simon McVittie, Chengwei Yang)
1291 • Be thread-safe by default on all platforms, even if
1292 dbus_threads_init_default() has not been called. For compatibility with
1293 older libdbus, library users should continue to call
1294 dbus_threads_init_default(): it is harmless to do so.
1295 (fd.o #54972, Simon McVittie)
1297 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
1299 • New API: dbus_setenv(), a simple wrapper around setenv().
1300 Note that this is not thread-safe. (fd.o #39196, Simon)
1302 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
1303 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
1304 (connect to a given bus, like dbus-monitor --address=ADDRESS).
1305 dbus-send --address still exists for backwards compatibility,
1306 but is no longer documented. (fd.o #48816, Andrey Mazo)
1309 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
1314 • Avoid an infinite busy-loop if a signal interrupts waitpid()
1315 (fd.o #68945, Simon McVittie)
1317 • Clean up memory for parent nodes when objects are unexported
1318 (fd.o #60176, Thomas Fitzsimmons)
1320 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
1321 documented. Previously, it assumed its second parameter was TRUE.
1322 (fd.o #69165, Chengwei Yang)
1324 • Escape addresses containing non-ASCII characters correctly
1325 (fd.o #53499, Chengwei Yang)
1327 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
1329 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
1330 (fd.o #65923, Chengwei Yang)
1332 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
1333 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
1335 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
1336 that was never va_start()ed (fd.o #66300, Chengwei Yang)
1338 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
1340 • fix a regression test on platforms with strict alignment (fd.o #67279,
1343 • Avoid calling function parameters "interface" since certain Windows headers
1344 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
1346 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
1348 • Various thread-safety improvements to static variables (fd.o #68610,
1351 • Make "make -j check" work (fd.o #68852, Simon McVittie)
1353 • Fix a NULL pointer dereference on an unlikely error path
1354 (fd.o #69327, Sviatoslav Chagaev)
1356 • Improve valgrind memory pool tracking (fd.o #69326,
1359 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
1362 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
1363 (fd.o #66107, Chengwei Yang)
1366 · If accept4() fails with EINVAL, as it can on older Linux kernels
1367 with newer glibc, try accept() instead of going into a busy-loop.
1368 (fd.o #69026, Chengwei Yang)
1369 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
1370 for instance on Hurd or older Linux with a new glibc, try without

1377 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
1378 · Use dbus-launch from the builddir for testing, not the installed copy
1379 (fd.o #37849, Chengwei Yang)
1380 · Fix compilation if writev() is unavailable (fd.o #69409,
1382 · Remove broken support for LOCAL_CREDS credentials passing, and
1383 document where each credential-passing scheme is used (fd.o #60340,

1411 D-Bus 1.7.4 (2013-06-13)
1414 The “but is your thread-safety thread-safe?” release.
1418 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
1419 of service for system services. Vulnerability reported by Alexandru Cornea.
1424 • The Windows version of libdbus now contains a C++ source file, used
1425 to provide global initialization when the library is loaded.
1426 gcc (mingw*) users should ensure that g++ is also installed.
1428 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
1429 and was never the recommended option) has been removed. Expat is now a
1434 • It should now be safe to call dbus_threads_init_default() from any thread,
1435 at any time. Authors of loadable modules and plugins that use libdbus
1436 should consider doing so during initialization.
1437 (fd.o #54972, Simon McVittie)
1439 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
1443 · dbus-run-session: experimental new tool to start a temporary D-Bus
1444 session, e.g. for regression tests or a text console, replacing
1445 certain uses of dbus-launch which weren't really correct
1446 (fd.o #39196, Simon)
1450 • In dbus-daemon, don't crash if a .service file starts with key=value
1451 (fd.o #60853, Chengwei Yang)
1454 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
1455 on a platform not defining LOG_PERROR, such as Solaris or QNX.
1456 This regressed in 1.7.0. (Simon)
1457 · Fix an assertion failure if we try to activate systemd services before
1458 systemd connects to the bus (fd.o #50199, Chengwei Yang)
1459 · Avoid compiler warnings for ignoring the return from write()
1463 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
1464 so that Windows finds them (fd.o #59733, Ralf Habacker)
1466 D-Bus 1.7.2 (2013-04-25)
1469 The “only partially opaque” release.
1471 Configuration changes:
1473 • On non-QNX Unix platforms, the default limit on fds per message in the
1474 session bus configuration has reduced from 4096 to 1024. The default
1475 limit used on the system bus was already 1024. On QNX, both limits are
1476 reduced further, to 128.
1480 • D-Bus Specification 0.21
1481 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
1482 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
1487 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
1488 (i.e. before allocating the slot) rather than returning junk

1495 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
1496 · Under systemd, log to syslog only, not stderr, avoiding duplication
1497 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
1498 · Under systemd, remove unnecessary dependency on syslog.socket
1499 (fd.o #63531, Cristian Rodríguez)

1518 The "Disingenuous Assertions" release.
1520 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
1521 remains the recommended version for long-term-supported distributions
1522 or the upcoming GNOME 3.8 release.
1524 Build-time configuration changes:
1526 • The --with-dbus-session-bus-default-address configure option is no longer
1527 supported. Use the new --with-dbus-session-bus-connect-address and
1528 --with-dbus-session-bus-listen-address options instead. On Windows, you
1529 usually want them to have the same argument; on Unix, the defaults are
1532 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
1533 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
1534 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
1536 • cmake/cross-compile.sh has been removed. Instead, please use a
1537 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
1538 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
1539 as documented in "info automake Cross-Compilation", and set
1540 PKG_CONFIG_PATH appropriately.
1544 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
1545 • man2html is no longer used.
1549 • D-Bus Specification 0.20
1550 · actually say that /org/freedesktop/DBus is the object that
1551 implements o.fd.DBus (fd.o #51865, Colin Walters)
1552 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
1553 · stop claiming that all basic types work just like INT32 (strings don't!)

1556 the outdated duplicate copies used when building with CMake.
1557 (fd.o #59805; Ralf Habacker, Simon McVittie)
1561 • In the activation helper, when compiled for tests, do not reset the system
1562 bus address, fixing the regression tests. (fd.o #52202, Simon)
1564 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
1565 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
1567 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

1586 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
1589 · The default session bus listening and connecting address is now
1590 "autolaunch:", which makes D-Bus on Windows interoperate with itself
1591 and GDBus "out of the box". Use the configure options and cmake variables
1592 described above if you require a different autolaunch scope.
1593 (fd.o #38201, Simon McVittie)
1594 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
1596 • Create session.d, system.d directories under CMake (fd.o #41319,

1604 • Follow up to CVE-2012-3524: The additional hardening
1605 work to use __secure_getenv() as a followup to bug #52202
1606 broke certain configurations of gnome-keyring. Given
1607 the difficulty of making this work without extensive
1608 changes to gnome-keyring, use of __secure_getenv() is

1650 (fd.o #51032, Simon McVittie)
1652 • Disconnect "developer mode" (assertions, verbose mode etc.) from
1653 Automake maintainer mode. D-Bus developers should now configure with
1654 --enable-developer. Automake maintainer mode is now on by default;
1655 distributions can disable it with --disable-maintainer-mode.
1656 (fd.o #34671, Simon McVittie)
1658 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
1659 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)

1753 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
1754 and SUSv2) is now required.
1756 • D-Bus Specification 0.19:
1757 · Formally define unique connection names and well-known bus names,
1758 and document best practices for interface, bus, member and error names,
1759 and object paths (fd.o #37095, Simon McVittie)
1760 · Document the search path for session and system services on Unix, and
1761 where they should be installed by build systems (fd.o #21620, fd.o #35306;
1763 · Document the systemd transport (fd.o #35232, Lennart Poettering)
1765 • Make dbus_threads_init() use the same built-in threading implementation
1766 as dbus_threads_init_default(); the user-specified primitives that it
1767 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
1769 • Allow all configured auth mechanisms, not just one (fd.o #45106,
1772 • Improve cmake build system (Ralf Habacker):
1773 · simplify XML parser dependencies (fd.o #41027)
1774 · generate build timestamp (fd.o #41029)
1775 · only create batch files on Windows
1776 · fix option and cache syntax
1777 · add help-options target
1778 · share dbus-arch-deps.h.in with autotools rather than having our
1779 own version (fd.o #41033)
1781 • Build tests successfully with older GLib, as found in e.g. Debian 6
1782 (fd.o #41219, Simon McVittie)
1784 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
1786 • Build documentation correctly if man2html doesn't support filenames on
1787 its command-line (fd.o #43875, Jack Nagel)
1789 • Improve test coverage. To get even more coverage, run the tests with
1790 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
1792 • Reduce the size of the shared library by moving functionality only used
1793 by dbus-daemon, tests etc. into their internal library and deleting
1794 unused code (fd.o #34976, #39759; Simon McVittie)
1796 • Add dbus-daemon --nopidfile option, overriding the configuration, for
1797 setups where the default configuration must include <pidfile/> to avoid
1798 breaking traditional init, but the pid file is in fact unnecessary; use
1799 it under systemd to improve startup time a bit (fd.o #45520,
1802 • Optionally (if configured --with-valgrind) add instrumentation to debug
1803 libdbus and associated tools more meaningfully under Valgrind
1804 (fd.o #37286, Simon McVittie)
1806 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
1808 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
1810 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
1811 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
1812 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
1815 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
1819 · Replace our broken reimplementation of recursive mutexes, which has
1820 been broken since 2006, with an ordinary pthreads recursive mutex
1821 (fd.o #43744; Sigmund Augdal, Simon McVittie)
1822 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
1823 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
1824 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
1825 · When running under systemd, use it instead of ConsoleKit to check
1826 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
1827 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
1828 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
1829 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
1830 (fd.o #41218, Simon McVittie)
1831 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
1832 helper doesn't obey environment variables to avoid privilege escalation
1833 attacks, so make the system bus follow the same rules
1834 (fd.o #21620, Simon McVittie)
1837 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
1838 Jesper Dam, Ralf Habacker)
1839 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
1842 D-Bus 1.5.8 (2011-09-21)
1845 The "cross-metering" release.
1847 In addition to dead code removal and refactoring, this release contains all
1848 of the bugfixes from 1.4.16.
1850 • Clean up dead code, and make more warnings fatal in development builds
1851 (fd.o #39231, fd.o #41012; Simon McVittie)
1853 • If full test coverage is requested via --enable-tests, strictly require
1854 Python, pygobject and dbus-python, which are required by some tests; if not,
1855 and Python is missing, skip those tests rather than failing
1856 (fd.o #37847, Simon McVittie)
1858 • When using cmake, provide the same version-info API in the installed headers
1859 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
1861 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
1863 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
1865 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
1868 • Fix duplicates in authors list (Ralf Habacker)
1870 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
1871 (fd.o #39879, Chris Mayo)
1873 • Fix a small memory leak, and a failure to report errors, when updating
1874 a service file entry for activation (fd.o #39230, Simon McVittie)
1877 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
1878 Brian Cameron, Simon McVittie)
1879 · On systems that use libcap-ng but not systemd, drop supplemental groups
1880 when switching to the daemon user (Red Hat #726953, Steve Grubb)
1881 · Make the cmake build work again on GNU platforms (fd.o #29228,
1883 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
1884 like Solaris (fd.o #40313, Dagobert Michelsen)
1885 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
1886 (fd.o #40235, Simon McVittie)
1887 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
1888 (fd.o #39987, Simon McVittie)
1889 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
1890 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
1893 · Fix compilation on MSVC, which doesn't understand "inline" with its
1894 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
1895 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
1896 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
1898 D-Bus 1.5.6 (2011-07-29)
1901 The "weird, gravy-like aftertaste" release.
1903 In addition to new features and refactoring, this release contains all of the
1904 bugfixes from 1.4.14.
1906 Potentially incompatible (Bustle and similar debugging tools will need
1907 changes to work as intended):
1909 • Do not allow match rules to "eavesdrop" (receive messages intended for a
1910 different recipient) by mistake: eavesdroppers must now opt-in to this
1911 behaviour by putting "eavesdrop='true'" in the match rule, which will
1912 not have any practical effect on buses where eavesdropping is not allowed
1913 (fd.o #37890, Cosimo Alfarano)
1917 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
1918 Cosimo Alfarano, Simon McVittie)
1919 · add the "eavesdrop" keyword to match rules
1920 · define eavesdropping, unicast messages and broadcast messages
1921 · stop claiming that match rules are needed to match unicast messages to you
1922 · promote the type system to be a top-level section
1924 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
1925 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
1926 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
1928 • Consistently use atomic operations on everything that is ever manipulated
1929 via atomic ops, as was done for changes to DBusConnection's refcount in
1930 1.4.12 (fd.o #38005, Simon McVittie)
1932 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
1935 • Make "make check" in a clean tree work, by not running tests until
1936 test data has been set up (fd.o #34405, Simon McVittie)
1938 • The dbus-daemon no longer busy-loops if it has a very large number of file
1939 descriptors (fd.o #23194, Simon McVittie)
1941 • Refactor message flow through dispatching to avoid locking violations if
1942 the bus daemon's message limit is hit; remove the per-connection link cache,
1943 which was meant to improve performance, but now reduces it (fd.o #34393,
1946 • Some cmake fixes (Ralf Habacker)
1948 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
1949 Simon McVittie, Lennart Poettering)
1951 • Stop storing two extra byte order indicators in each D-Bus message
1952 (fd.o #38287, Simon McVittie)
1954 • Add an optional Stats interface which can be used to get statistics from
1955 a running dbus-daemon if enabled at configure time with --enable-stats
1956 (fd.o #34040, Simon McVittie)
1958 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
1960 • Documentation (fd.o #36156, Simon McVittie):
1961 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
1962 · install more documentation automatically, including man2html output
1963 · put dbus.devhelp in the right place (it must go in ${htmldir})
1966 · look for system services in /lib/dbus-1/system-services in addition to all
1967 the other well-known locations; note that this should always be /lib,
1968 even on platforms where shared libraries on the root FS would go in /lib64,
1969 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
1970 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
1972 • Windows-specific (Ralf Habacker):
1973 · fix use of a mutex for autolaunch server detection
1974 · don't crash on malloc failure in _dbus_printf_string_upper_bound
1976 D-Bus 1.5.4 (2011-06-10)
1979 Security (local denial of service):
1981 • Byte-swap foreign-endian messages correctly, preventing a long-standing
1982 local DoS if foreign-endian messages are relayed through the dbus-daemon
1983 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
1984 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
1988 • The constant to use for an infinite timeout now has a name,
1989 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
1990 which can be used for source compatibility with older versions of libdbus.
1992 • If GLib and DBus-GLib are already installed, more tests will be built,
1993 providing better coverage. The new tests can also be installed via
1994 ./configure --enable-installed-tests
1995 for system integration testing, if required. (fd.o #34570, Simon McVittie)
1999 • Consistently use atomic operations for the DBusConnection's refcount,
2000 fixing potential threading problems (fd.o #38005, Simon McVittie)
2002 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2003 small (300KiB on x86-64) and it frequently doesn't work in unusual
2004 toolchains. To optimize for minimum installed size, you should benchmark
2005 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2006 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2008 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2009 (fd.o #35880, Timothy Redaelli)
2011 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2012 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2014 • Windows-specific changes:
2015 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2017 D-Bus 1.5.2 (2011-06-01)
2020 The "Boar Hunter" release.
2022 Notes for distributors:
2024 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2025 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2026 toolchain supports it reliably, via something like:
2028 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2030 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2034 • D-Bus Specification v0.17
2035 · Reserve the extra characters used in signatures by GVariant
2036 (fd.o #34529, Simon McVittie)
2037 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2038 • Don't force -fPIE: distributions and libtool know better than we do whether
2039 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2040 • Allow --disable-gc-sections, in case your toolchain offers the
2041 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2042 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2043 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2044 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2045 • Ensure that maintainers upload documentation with the right permissions
2046 (fd.o #36130, Simon McVittie)
2047 • Don't force users of libdbus to be linked against -lpthread, -lrt
2048 (fd.o #32827, Simon McVittie)
2049 • Log system-bus activation information to syslog (fd.o #35705,
2051 • Log messages dropped due to quotas to syslog (fd.o #35358,
2053 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
2054 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
2055 (fd.o #35228, Lennart Poettering)
2056 • In the regression tests, don't report fds as "leaked" if they were open
2057 on startup (fd.o #35173, Simon McVittie)
2058 • Make dbus-monitor bail out if asked to monitor more than one bus,
2059 rather than silently using the last one (fd.o #26548, Will Thompson)
2060 • Clarify documentation (fd.o #35182, Simon McVittie)
2061 • Clean up minor dead code and some incorrect error handling
2062 (fd.o #33128, fd.o #29881; Simon McVittie)
2063 • Check that compiler options are supported before using them (fd.o #19681,
2066 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
2068 D-Bus 1.5.0 (2011-04-11)
2071 The "you never know when you need to tow something from your giant
2072 flying shark" release.
2074 • D-Bus Specification v0.16
2075 · Add support for path_namespace and arg0namespace in match rules
2076 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
2077 · Make argNpath support object paths, not just object-path-like strings,
2078 and document it better (fd.o #31818, Will Thompson)
2079 • Let the bus daemon implement more than one interface (fd.o #33757,
2081 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2083 • Require user intervention to compile with missing 64-bit support
2084 (fd.o #35114, Simon McVittie)
2085 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
2086 • Raise UnknownObject instead of UnknownMethod for calls to methods on
2087 paths that are not part of the object tree, and UnknownInterface for calls
2088 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
2090 D-Bus 1.4.8 (2011-04-08)
2093 The "It's like the beginning of a lobster" release.
2095 • Rename configure.in to configure.ac, and update it to modern conventions
2096 (fd.o #32245; Javier Jardón, Simon McVittie)
2097 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
2099 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
2100 --disable-x11-autolaunch configure option to prevent it altogether
2101 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
2102 • Install the documentation, and an index for Devhelp (fd.o #13495,
2103 Debian #454142; Simon McVittie, Matthias Clasen)
2104 • If checks are not disabled, check validity of string-like types and
2105 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
2106 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
2107 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
2108 • Break up a huge conditional in config-parser so gcov can produce coverage
2109 data (fd.o #10887, Simon McVittie)
2110 • List which parts of the Desktop Entry specification are applicable to
2111 .service files (fd.o #19159, Sven Herzberg)
2112 • Don't suppress service activation if two services have the same Exec=
2113 (fd.o #35750, Colin Walters)

2123 The "1, 2, miss a few, 99, 100" release.
2125 • Remove unfinished changes intended to support GTest-based tests,
2126 which were mistakenly included in 1.4.4
2128 D-Bus 1.4.4 (2010-02-17)
2131 • Switch back to using even micro versions for stable releases; 1.4.1
2132 should have been called 1.4.2, so skip that version number
2133 • Don't leave bad file descriptors being watched when spawning processes,
2134 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
2135 also LP#656134, LP#680444, LP#713157)
2136 • Check for MSG_NOSIGNAL correctly
2137 • Fix failure to detect abstract socket support (fd.o #29895)
2138 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
2139 (fd.o #32262, NB#180486)
2140 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,

2166 D-Bus 1.4.1 (20 December 2010)
2169 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
2170 crash the bus. The existing restriction to 64-levels of nesting previously
2171 only applied to the static type signature; now it also applies to dynamic
2172 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
2174 • OS X portability fixes, including launchd support.
2175 • Windows autolaunch improvements.
2176 • Various bug fixes.

2190 - ability for dbus-send to send to any bus (--address)
2191 - file descriptor passing on Unix socket transports
2192 - use of GCC atomic intrinsics for better processor support
