1 D-Bus 1.10.6 (UNRELEASED)
4 D-Bus 1.10.4 (2015-11-17)
7 The “Frostburn Canyon” release.
11 • GetConnectionCredentials, GetConnectionUnixUser and
12 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
13 will now return details of the dbus-daemon itself. This is required
14 to be able to call SetEnvironment on systemd.
15 (fd.o #92857, Jan Alexander Steffens)
19 • Make UpdateActivationEnvironment always fail with AccessDenied on the
20 system bus. Previously, it was possible to configure it so root could
21 call it, but the environment variables were not actually used,
22 because the launch helper would discard them.
23 (fd.o #92857, Jan Alexander Steffens)
25 • On Unix with --systemd-activation on a user bus, make
26 UpdateActivationEnvironment pass on its arguments to systemd's
27 SetEnvironment method, solving inconsistency between the environments
28 used for traditional activation and systemd user-service activation.
29 (fd.o #92857, Jan Alexander Steffens)
31 • On Windows, don't crash if <syslog/> or --syslog is used
32 (fd.o #92538, Ralf Habacker)
34 • On Windows, fix a memory leak when setting a DBusError from a Windows
35 error (fd.o #92721, Ralf Habacker)
37 • On Windows, don't go into infinite recursion if we abort the process
38 with backtraces enabled (fd.o #92721, Ralf Habacker)
40 • Fix various failing tests, variously on Windows and cross-platform:
41 · don't test system.conf features (users, groups) that only make sense
42 on the system bus, which is not supported on Windows
43 · don't call _dbus_warn() when we skip a test, since it is fatal
44 · fix computation of expected <standard_session_servicedirs/>
45 · when running TAP tests, translate newlines to Unix format, fixing
46 cross-compiled tests under Wine on Linux
47 · don't stress-test refcounting under Wine, where it's really slow
48 · stop assuming that a message looped-back to the test will be received
50 · skip some system bus tests on Windows since they make no sense there
51 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
53 D-Bus 1.10.2 (2015-10-26)
56 The “worst pies in London” release.
60 • Correct error handling for activation: if there are multiple attempts
61 to activate the same service and it fails immediately, the first attempt
62 would get the correct reply, but the rest would time out. We now send
63 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
65 • If BecomeMonitor is called with a syntactically invalid match rule,
66 don't crash with an assertion failure, fixing a regression in 1.9.10.
67 This was not exploitable as a denial of service, because the check
68 for a privileged user is done first. (fd.o #92298, Simon McVittie)
70 • On Linux with --enable-user-session, add the bus address to the
71 environment of systemd services for better backwards compatibility
72 (fd.o #92612, Jan Alexander Steffens)
74 • On Windows, fix the logic for replacing the installation prefix
75 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
77 • On Windows, if installed in the conventional layout with ${prefix}/etc
78 and ${prefix}/share, use relative paths between bus configuration files
79 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
81 • Make more of the regression tests pass in Windows builds (fd.o #92538,
84 D-Bus 1.10.0 (2015-08-25)
89 This is a new stable branch, recommended for use in OS distributions.
93 • distribute test/tap-test.sh.in, even if the tarball was built without
94 tests enabled (fd.o #91684, Simon McVittie)
95 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
97 Summary of major changes since 1.8.0:
99 • The basic setup for the well-known system and session buses is
100 now done in read-only files in ${datadir} (normally /usr/share).
101 See the NEWS entry for 1.9.18 for details.
103 • AppArmor integration has been merged, with features similar to the
104 pre-existing SELinux integration. It is mostly compatible with the
105 patches previously shipped by Ubuntu, with one significant change:
106 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
107 by GetConnectionCredentials and was not included.
109 • The --enable-user-session configure option can be enabled
110 by OS integrators intending to use systemd to provide a session bus
111 per user (in effect, treating all concurrent graphical and non-graphical
112 login sessions as one large session).
114 • The new listenable address mode "unix:runtime=yes" listens on
115 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
116 user session. libdbus and "dbus-launch --autolaunch" will connect to
117 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
120 • All executables are now dynamically linked to libdbus-1.
121 Previously, some executables, most notably dbus-daemon, were statically
122 linked to a specially-compiled variant of libdbus. This results in
123 various private functions in the _dbus namespace being exposed by the
124 shared library. These are not API, and must not be used outside
125 the dbus source tree.
127 • On platforms with ELF symbol versioning, all public symbols
128 are versioned LIBDBUS_1_3.
132 • org.freedesktop.DBus.GetConnectionCredentials returns
133 LinuxSecurityLabel where supported
134 • org.freedesktop.DBus.Monitoring interface (privileged)
135 · BecomeMonitor method supersedes match rules with eavesdrop=true,
136 which are now deprecated
137 • org.freedesktop.DBus.Stats interface (semi-privileged)
138 · now enabled by default
139 · new GetAllMatchRules method
140 • org.freedesktop.DBus.Verbose interface (not normally compiled)
141 · toggles the effect of DBUS_VERBOSE
146 • dbus-update-activation-environment
148 New optional dependencies:
150 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
151 • Complete documentation requires Ducktype and yelp-tools
152 • Full test coverage requires GLib 2.36 and PyGI
153 • AppArmor integration requires libapparmor and optionally libaudit
155 Dependencies removed:
159 D-Bus 1.9.20 (2015-08-06)
162 The “Remember Tomorrow” release.
164 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
169 • Don't second-guess what the ABI of poll() is, allowing it to be used
170 on Integrity RTOS and other unusual platforms (fd.o #90314;
171 Rolland Dudemaine, Simon McVittie)
173 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
174 both enabled (fd.o #89225, Simon McVittie)
176 • Log audit events for AppArmor/SELinux policy violations whenever
177 we have CAP_AUDIT_WRITE, even if not the system bus
178 (fd.o #83856, Laurent Bigonville)
180 D-Bus 1.9.18 (2015-07-21)
183 The “Pirate Elite” release.
185 Configuration changes:
187 • The basic setup for the well-known system and session buses is now done
188 in read-only files in ${datadir}, moving a step closer to systems
189 that can operate with an empty /etc directory. In increasing order
192 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
193 the default message policies.
194 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
195 dbus still installs a trivial version of each, for documentation
196 purposes; putting configuration directives in these files is deprecated.
197 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
198 to install "drop-in" configuration snippets (any packages
199 using those directories should explicitly depend on at least this
201 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
202 or third-party software to install "drop-in" configuration snippets
203 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
206 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
207 and "s*" refers to either system or session as appropriate.
209 (fd.o #89280, Dimitri John Ledkov)
213 • Fix a memory leak when GetConnectionCredentials() succeeds
214 (fd.o #91008, Jacek Bukarewicz)
216 • Ensure that dbus-monitor does not reply to messages intended for others,
217 resulting in its own disconnection (fd.o #90952, Simon McVittie)
219 D-Bus 1.9.16 (2015-05-14)
222 The “titanium barns” release.
226 • Automake 1.13 is now required when compiling from git or modifying
231 • On Unix platforms, change the default configuration for the session bus
232 to only allow EXTERNAL authentication (secure kernel-mediated
233 credentials-passing), as was already done for the system bus.
235 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
236 unpredictable pseudo-random numbers.
238 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
239 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
240 NFS or similar, you will need to reconfigure the session bus to accept
241 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
244 (fd.o #90414, Simon McVittie)
246 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
247 transport, UUIDs or any other reason, fail if we cannot obtain entropy
248 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
249 occurs, instead of silently falling back to low-entropy pseudorandom
250 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
254 • Add dbus_message_iter_get_element_count()
255 (fd.o #30350; Christian Dywan, Simon McVittie)
257 • Introduce new internal DBusSocket and DBusPollable types so we can
258 stop treating the Windows SOCKET type as if it was int. DBusSocket
259 is specifically a socket, cross-platform. DBusPollable is whatever
260 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
261 (fd.o #89444; Ralf Habacker, Simon McVittie)
263 • All regression tests now output TAP <https://testanything.org/>
264 (fd.o #89846, Simon McVittie)
266 • Internal APIs consistently use signed values for timestamps
267 (fd.o #18494, Peter McCurdy)
269 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
270 (fd.o #88812, Simon McVittie)
272 • Clean up a lot of compiler warnings
273 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
277 • Add locking to DBusCounter's reference count and notify function
278 (fd.o #89297, Adrian Szyndela)
280 • Ensure that DBusTransport's reference count is protected by the
281 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
283 • Correctly release DBusServer mutex before early-return if we run out
284 of memory while copying authentication mechanisms (fd.o #90021,
287 • Make dbus-test-tool and dbus-update-activation-environment portable
288 to Windows (fd.o #90089, Ralf Habacker)
290 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
291 Ralf Habacker, Simon McVittie)
293 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
296 • Clean up some memory and fd leaks in test code and tools
297 (fd.o #90021, Ralf Habacker)
299 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
300 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
302 • CMake generates a versioned shared library even if the revision is 0,
303 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
305 D-Bus 1.9.14 (2015-03-02)
308 The “don't stand in the poison cloud” release.
312 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
313 were previously linked to a static version of libdbus.
315 • The tests no longer require dbus-glib in order to exercise the libdbus
316 shared library; they are always linked to libdbus now.
318 Build-time configuration:
320 • The new --enable-user-session option, off by default, can be enabled
321 by OS integrators intending to use systemd to provide a session bus
322 per user (in effect, treating all concurrent graphical and non-graphical
323 login sessions as one large session)
327 • All executables are now linked dynamically to libdbus.
328 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
330 • On platforms that support them (GNU libc and possibly others),
331 libdbus now has versioned symbols for its public API.
332 All public symbols (visible in the header files) are currently
333 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
334 dbus_internal have a version that changes with each release, and
335 must not be used by applications. (also fd.o #83115)
337 • New listenable address mode "unix:runtime=yes" which listens on
338 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
339 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
341 • Add optional systemd units for a per-user bus listening on
342 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
344 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
345 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
348 • New dbus-update-activation-environment tool uploads environment
349 variables to "dbus-daemon --session" and optionally "systemd --user",
350 primarily as a way to keep the per-user bus compatible with
351 distributions' existing X11 login scripts (also fd.o #61301)
353 • <includedir/> elements in dbus-daemon configuration are now silently
354 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
356 • Add microsecond-resolution timestamps to the default output of
357 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
361 • Fix a race condition in the 'monitor' test introduced in 1.9.10
362 (fd.o #89222, Simon McVittie)
364 D-Bus 1.9.12 (2015-02-19)
367 The “monster lasagna” release.
371 • Ducktype and yelp-tools are now required to build complete documentation
372 (they are optional for normal builds).
376 • D-Bus Specification version 0.26
377 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
378 · document the BecomeMonitor method
380 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
381 (fd.o #89041; Tyler Hicks, Simon McVittie)
383 • On Linux, add support for AppArmor mediation of message sending and
384 receiving and name ownership (paralleling existing SELinux mediation
385 support), and eavesdropping (a new check, currently AppArmor-specific)
386 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
388 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
389 that have printable ASCII contents; we previously only did this for
390 unterminated bytestrings (fd.o #89109, Simon McVittie)
392 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
394 • On Windows, add WindowsSID to GetConnectionCredentials
395 (fd.o #54445, Ralf Habacker)
397 • Improve clarity of dbus-monitor --profile output and add more columns
398 (fd.o #89165, Ralf Habacker)
400 • Add a man page for dbus-test-tool, and build it under CMake as well
401 as Autotools (fd.o#89086, Simon McVittie)
403 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
404 to control it at runtime, overriding the DBUS_VERBOSE environment variable
405 (fd.o #88896, Ralf Habacker)
409 • Reduce the number of file descriptors used in the fd-passing test,
410 avoiding failure under the default Linux fd limit, and automatically
411 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
413 D-Bus 1.9.10 (2015-02-09)
416 The “sad cyborgs” release.
418 Security fixes merged from 1.8.16:
420 • Do not allow non-uid-0 processes to send forged ActivationFailure
421 messages. On Linux systems with systemd activation, this would
422 allow a local denial of service: unprivileged processes could
423 flood the bus with these forged messages, winning the race with
424 the actual service activation and causing an error reply
425 to be sent back when service auto-activation was requested.
426 This does not prevent the real service from being started,
427 so the attack only works while the real service is not running.
428 (CVE-2015-0245, fd.o #88811; Simon McVittie)
432 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
433 similar tools receive messages without altering the security properties
434 of the system bus, by calling the new BecomeMonitor method on a
435 private connection. This bypasses the normal <allow> and <deny> rules
436 entirely, so to preserve normal message-privacy assumptions, only root
437 is allowed to do this on the system bus. Restricted environments,
438 such as Linux with LSMs, should lock down access to the Monitoring
439 interface. (fd.o #46787, Simon McVittie)
441 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
442 dbus-daemon supports it and access permissions allow it.
443 It still supports the previous approach ("eavesdropping" match rules)
444 for compatibility with older bus daemons. (fd.o #46787, Simon)
446 • dbus-monitor can now log the message stream as binary data for later
447 analysis, with either no extra framing beyond the normal D-Bus headers,
448 or libpcap-compatible framing treating each D-Bus message
449 as a captured packet. (fd.o #46787, Simon)
453 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
455 • On Unix, forcibly terminate regression tests after 60 seconds to
456 prevent them from blocking continuous integration frameworks
459 D-Bus 1.9.8 (2015-02-03)
462 The “all the types of precipitation” release.
466 • full test coverage now requires GLib 2.36
467 • full test coverage now requires PyGI (PyGObject 3,
468 "import gi.repository.GObject") instead of the
469 obsolete PyGObject 2 ("import gobject")
473 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
475 • better regression test coverage, including systemd activation
476 (fd.o #57952, #88810; Simon McVittie)
480 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
481 turned off (fd.o #88808, Simon McVittie)
483 • TCP sockets on Windows no longer fail to listen approximately 1 time
484 in 256, caused by a logic error that should have always made it fail but
485 was mitigated by incorrect endianness for the port number
486 (fd.o #87999, Ralf Habacker)
488 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
490 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
491 previous 64, completing a previous fix which only worked under
492 Autotools (fd.o #71297, Ralf Habacker)
494 • on Windows, if the IP family is unspecified only use IPv4,
495 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
497 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
499 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
501 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
504 D-Bus 1.9.6 (2015-01-05)
507 The “I do have a bread knife” release.
511 • Do not allow calls to UpdateActivationEnvironment from uids other than
512 the uid of the dbus-daemon. If a system service installs unsafe
513 security policy rules that allow arbitrary method calls
514 (such as CVE-2014-8148) then this prevents memory consumption and
515 possible privilege escalation via UpdateActivationEnvironment.
517 We believe that in practice, privilege escalation here is avoided
518 by dbus-daemon-launch-helper sanitizing its environment; but
519 it seems better to be safe.
521 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
522 on object paths other than /org/freedesktop/DBus. Some system services
523 install unsafe security policy rules that allow arbitrary method calls
524 to any destination, method and interface with a specified object path;
525 while less bad than allowing arbitrary method calls, these security
526 policies are still harmful, since dbus-daemon normally offers the
527 same API on all object paths and other system services might behave
532 • Add missing initialization so GetExtendedTcpTable doesn't crash on
533 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
535 D-Bus 1.9.4 (2014-11-24)
538 The “extra-sturdy caramel” release.
542 • Partially revert the CVE-2014-3639 patch by increasing the default
543 authentication timeout on the system bus from 5 seconds back to 30
544 seconds, since this has been reported to cause boot regressions for
545 some users, mostly with parallel boot (systemd) on slower hardware.
547 On fast systems where local users are considered particularly hostile,
548 administrators can return to the 5 second timeout (or any other value
549 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
552 <limit name="auth_timeout">5000</limit>
555 (fd.o #86431, Simon McVittie)
557 • Add a message in syslog/the Journal when the auth_timeout is exceeded
558 (fd.o #86431, Simon McVittie)
560 • Send back an AccessDenied error if the addressed recipient is not allowed
561 to receive a message (and in builds with assertions enabled, don't
562 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
564 D-Bus 1.9.2 (2014-11-10)
567 The “structurally unsound flapjack” release.
571 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
572 so that CVE-2014-3636 part A cannot exhaust the system bus'
573 file descriptors, completing the incomplete fix in 1.8.8.
574 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
578 • D-Bus Specification version 0.25
579 · new value 'const' for EmitsChangedSignal annotation
580 (fd.o #72958, Lennart Poettering)
581 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
582 (fd.o #83449; Lennart Poettering, Simon McVittie)
583 · annotate table of types with reserved/basic/container, and for
584 basic types, fixed/string-like
585 · clarify arbitrary limits by quoting them in mebibytes
587 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
588 (fd.o #83449, Simon McVittie)
590 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
591 useful for debugging and performance testing:
592 · dbus-test-tool spam: send repeated messages
593 · dbus-test-tool echo: send an empty reply for all method calls
594 · dbus-test-tool black-hole: do not reply to method calls
595 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
597 • Add support for process ID in credentials-passing on NetBSD
598 (fd.o #69702, Patrick Welche)
600 • Add an example script to find potentially undesired match rules
601 (fd.o #84598, Alban Crequy)
603 • Document the central assumption that makes our use of credentials-passing
604 secure (fd.o #83499, Simon McVittie)
606 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
607 and add some links to GDBus and QtDBus documentation (fd.o #25140,
612 • Use a less confusing NoReply message when disconnected with a reply pending
613 (fd.o #76112, Simon McVittie)
615 • Make the .pc file relocatable by letting pkg-config do all variable
616 expansion itself (fd.o #75858, Руслан Ижбулатов)
618 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
619 (fd.o #85563, Patrick Welche)
621 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
623 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
624 do not lose the exec() errno (fd.o #24821, Simon McVittie)
626 • Do not fail the tests if a parent process has leaked non-close-on-exec
627 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
629 • Do not fail the tests on Unix platforms with incomplete
630 credentials-passing support, but do fail if we can't pass credentials
631 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
632 (fd.o #69702, Simon McVittie)
634 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
635 when building with cmake, and expand test coverage there
636 (fd.o #73689; Ralf Habacker, Simon McVittie)
638 D-Bus 1.9.0 (2014-10-01)
641 The “tiered cheeses” release.
645 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
646 requires either the libsystemd or libsd-daemon shared library, dropping the
647 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
649 Build-time configuration changes:
651 • The Stats interface is now enabled by default, and locked-down to
652 root-only on the system bus. Configure with --disable-stats
653 to disable it altogether on memory- or disk-constrained systems,
654 or see ${docdir}/examples/ to open it up to non-root users on the
655 system bus or restrict access on the session bus.
656 (fd.o #80759; Simon McVittie, Alban Crequy)
658 • The CMake build system now builds the same shared library name as Autotools
659 on at least Linux and Windows:
660 - on Linux (and perhaps other Unix platforms), it previously built
661 libdbus-1.so, but now builds libdbus-1.so.3.* with development
662 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
663 - on Windows, it previously built either libdbus-1.dll (release) or
664 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
665 libdbus-1.dll for compatibility with older applications.
666 (fd.o #74117, Ralf Habacker)
670 • D-Bus Specification version 0.24
671 · document how to quote match rules (fd.o #24307, Simon McVittie)
672 · explicitly say that most message types never expect a reply
673 regardles of whether they have NO_REPLY_EXPECTED
674 (fd.o #75749, Simon McVittie)
676 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
677 initial latency (fd.o #75544, Matt Hoosier)
679 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
680 (fd.o #69702, Patrick Welche)
682 • in dbus-monitor, print more information about file descriptors
683 (fd.o #80603, Alban Crequy)
685 • do not install system bus configuration if built for Windows
686 (fd.o #83583; Ralf Habacker, Simon McVittie)
688 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
690 • Add a regression test for file descriptor passing (fd.o #83622,
695 • fix an incorrect error message if a Unix socket path is too long
696 (fd.o #73887, Antoine Jacoutot)
698 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
699 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
701 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
702 in ps(1) (fd.o #69716, Chengwei Yang)
704 • avoid calling poll() with timeout < -1, which is considered invalid
705 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
707 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
708 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
709 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
711 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
713 • Documentation improvements
714 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
716 • in dbus-monitor, do not leak file descriptors that we have monitored
717 (fd.o #80603, Alban Crequy)
719 • Set the close-on-exec flag for the inotify file descriptor, even
720 if built with CMake or older libc (fd.o #73689, Simon McVittie)
722 • Remove some LGPL code from the Windows dbus-daemon
723 (fd.o #57272, Ralf Habacker)
725 D-Bus 1.8.8 (2014-09-16)
728 The "smashy smashy egg man" release.
732 • Do not accept an extra fd in the padding of a cmsg message, which
733 could lead to a 4-byte heap buffer overrun.
734 (CVE-2014-3635, fd.o #83622; Simon McVittie)
736 • Reduce default for maximum Unix file descriptors passed per message
737 from 1024 to 16, preventing a uid with the default maximum number of
738 connections from exhausting the system bus' file descriptors under
739 Linux's default rlimit. Distributors or system administrators with a
740 more restrictive fd limit may wish to reduce these limits further.
742 Additionally, on Linux this prevents a second denial of service
743 in which the dbus-daemon can be made to exceed the maximum number
744 of fds per sendmsg() and disconnect the process that would have
746 (CVE-2014-3636, fd.o #82820; Alban Crequy)
748 • Disconnect connections that still have a fd pending unmarshalling after
749 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
750 removing the possibility of creating an abusive connection that cannot be
751 disconnected by setting up a circular reference to a connection's
753 (CVE-2014-3637, fd.o #80559; Alban Crequy)
755 • Reduce default for maximum pending replies per connection from 8192 to 128,
756 mitigating an algorithmic complexity denial-of-service attack
757 (CVE-2014-3638, fd.o #81053; Alban Crequy)
759 • Reduce default for authentication timeout on the system bus from
760 30 seconds to 5 seconds, avoiding denial of service by using up
761 all unauthenticated connection slots; and when all unauthenticated
762 connection slots are used up, make new connection attempts block
763 instead of disconnecting them.
764 (CVE-2014-3639, fd.o #80919; Alban Crequy)
768 • Check for libsystemd from systemd >= 209, falling back to
769 the older separate libraries if not found (Umut Tezduyar Lindskog,
772 • On Linux, use prctl() to disable core dumps from a test executable
773 that deliberately raises SIGSEGV to test dbus-daemon's handling
774 of that condition (fd.o #83772, Simon McVittie)
776 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
779 • Improve documentation for running tests on Windows (fd.o #41252,
782 D-Bus 1.8.6 (2014-06-02)
787 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
788 the message. This prevents an attack in which a malicious client can
789 make dbus-daemon disconnect a system service, which is a local
791 (fd.o #80163, CVE-2014-3532; Alban Crequy)
793 • Track remaining Unix file descriptors correctly when more than one
794 message in quick succession contains fds. This prevents another attack
795 in which a malicious client can make dbus-daemon disconnect a system
797 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
798 Simon McVittie, Alban Crequy)
802 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
803 attach to a session, kill the dbus-daemon as intended
804 (fd.o #74698, Роман Донченко)
806 D-Bus 1.8.4 (2014-06-10)
811 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
812 flaw in dbus-daemon, part of the reference implementation of D-Bus.
813 Additionally, in highly unusual environments the same flaw could lead to
814 a side channel between processes that should not be able to communicate.
815 (CVE-2014-3477, fd.o #78979)
817 D-Bus 1.8.2 (2014-04-30)
820 The “nobody wants red” release.
824 • in the CMake build system, add some hints for Linux users cross-compiling
825 Windows D-Bus binaries to be able to run tests under Wine
826 (fd.o #41252, Ralf Habacker)
828 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
832 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
833 to /var/lib/dbus/machine-id instead of generating an entirely new ID
834 (fd.o #77941, Simon McVittie)
836 • if dbus-launch receives an X error very quickly, do not kill
837 unrelated processes (fd.o #74698, Роман Донченко)
839 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
840 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
842 • cope with \r\n newlines in regression tests, since on Windows,
843 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
845 D-Bus 1.8.0 (2014-01-20)
848 The “Wolverine distrusts my printer” release.
850 This starts a new stable branch. The 1.6.x branch is now considered to be
851 outdated, and will only receive fixes for serious bugs such as security
852 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
853 are unlikely to get any more releases, but if distributors still need to
854 support them, please share security patches via upstream.
856 Summary of changes since 1.6.x:
858 • libdbus always behaves as if dbus_threads_init_default() had been called
859 (thread-safety by default)
860 • new dbus-run-session tool, replacing certain misuses of dbus-launch
861 • dbus-monitor can talk to outdated versions of dbus-daemon again
862 • new org.freedesktop.DBus.GetConnectionCredentials method
863 • GetConnectionUnixProcessID also works correctly on Windows, returning
864 the Windows process ID
865 • GetConnectionWindowsSID returns the correct SID on Windows
866 • expat is required, libxml2 can no longer be used as a substitute
867 • the userDB cache is required, and cannot be disabled
868 • a 64-bit integer type (either int, long, long long or _int64) is required
869 • better systemd-journald integration on Linux
870 • fixed long-standing fd and array leaks when failing to parse a message
871 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
872 when using certain object-path allocation patterns, notably in Avahi
873 • better defaults for Windows support
874 • better CMake support
875 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
876 • the source language for the man pages is now Docbook XML
878 Enhancements since 1.7.10:
880 • Enhance the CMake build system to check for GLib and compile/run
881 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
885 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
888 • fix compilation of systemd journal support on older systemd versions where
889 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
891 • fix compilation on older MSVC versions by including stdlib.h
892 (fd.o #73455, Ralf Habacker)
894 • Allow <allow_anonymous/> to appear in an included configuration file
895 (fd.o #73475, Matt Hoosier)
897 Test behaviour changes since 1.7.10:
899 • If the tests crash with an assertion failure, they no longer default to
900 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
901 environment if you want the old behaviour.
903 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
904 can be run with an external dbus-daemon by setting
905 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
906 an unusually-configured dbus-daemon are skipped.
908 D-Bus 1.7.10 (2014-01-06)
911 The “weighted companion cube” release.
913 This is a release candidate for D-Bus 1.8.
915 D-Bus Specification 0.23:
917 • don't require messages with no INTERFACE to be dispatched
918 (fd.o #68597, Simon McVittie)
920 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
923 • define "listenable" and "connectable" addresses, and discuss
924 the difference (fd.o #61303, Simon McVittie)
928 • support printing Unix file descriptors in dbus-send, dbus-monitor
929 (fd.o #70592, Robert Ancell)
931 • don't install systemd units if --disable-systemd is given
932 (fd.o #71818, Chengwei Yang)
936 • don't leak memory on out-of-memory while listing activatable or
937 active services (fd.o #71526, Radoslaw Pajak)
939 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
941 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
943 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
944 and DBUS__SEND_MSG are numerically equal to their values in the
945 reference policy (fd.o #88719, osmond sun)
947 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
948 (fd.o #71366, Matt Fischer)
950 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
951 winsock2.h (fd.o #71405, Matt Fischer)
953 • do not return failure from _dbus_read_nonce() with no error set,
954 preventing a potential crash (fd.o #72298, Chengwei Yang)
956 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
957 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
959 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
960 which doesn't do anything anyway on at least Linux and FreeBSD
961 (fd.o #69492, Simon McVittie)
963 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
964 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
965 for credentials more correctly (fd.o #69492, Simon McVittie)
967 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
968 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
971 • refresh cached policy rules for existing connections when bus
972 configuration changes (fd.o #39463, Chengwei Yang)
974 D-Bus 1.7.8 (2013-11-01)
977 The “extreme hills” release.
981 • If systemd support is enabled, libsystemd-journal is now required.
985 • When activating a non-systemd service under systemd, annotate its
986 stdout/stderr with its bus name in the Journal. Known limitation:
987 because the socket is opened before forking, the process will still be
988 logged as if it had dbus-daemon's process ID and user ID.
989 (fd.o #68559, Chengwei Yang)
991 • Document more configuration elements in dbus-daemon(1)
992 (fd.o #69125, Chengwei Yang)
996 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
997 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
999 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
1000 disallowed method calls to the audit log, fixing a regression in 1.7.6
1001 (fd.o #49062, Colin Walters)
1003 • path_namespace='/' in match rules incorrectly matched nothing; it
1004 now matches everything. (fd.o #70799, Simon McVittie)
1006 D-Bus 1.7.6 (2013-10-09)
1009 The “CSI Shrewsbury” release.
1011 Build-time configuration changes:
1013 • Directory change notification via dnotify on Linux is no longer
1014 supported; it hadn't compiled successfully since 2010 in any case.
1015 If you don't have inotify (Linux) or kqueue (*BSD), you will need
1016 to send SIGHUP to the dbus-daemon when its configuration changes.
1017 (fd.o #33001, Chengwei Yang)
1019 • Compiling with --disable-userdb-cache is no longer supported;
1020 it didn't work since at least 2008, and would lead to an extremely
1021 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
1024 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
1025 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
1026 with the Autotools build system. (fd.o #66142, Chengwei Yang)
1028 • --with-valgrind=auto enables Valgrind instrumentation if and only if
1029 valgrind headers are available. The default is still --with-valgrind=no.
1030 (fd.o #56925, Simon McVittie)
1034 • Platforms with no 64-bit integer type are no longer supported.
1035 (fd.o #65429, Simon McVittie)
1037 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
1039 • Full test coverage no longer requires dbus-glib, although the tests do not
1040 exercise the shared library (only a static copy) if dbus-glib is missing.
1041 (fd.o #68852, Simon McVittie)
1045 • D-Bus Specification 0.22
1046 · Document GetAdtAuditSessionData() and
1047 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
1048 · Fix example .service file (fd.o #66481, Chengwei Yang)
1049 · Don't claim D-Bus is "low-latency" (lower than what?), just
1050 give factual statements about it supporting async use
1051 (fd.o #65141, Justin Lee)
1052 · Document the contents of .service files, and the fact that
1053 system services' filenames are constrained
1054 (fd.o #66608; Simon McVittie, Chengwei Yang)
1056 • Be thread-safe by default on all platforms, even if
1057 dbus_threads_init_default() has not been called. For compatibility with
1058 older libdbus, library users should continue to call
1059 dbus_threads_init_default(): it is harmless to do so.
1060 (fd.o #54972, Simon McVittie)
1062 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
1064 • New API: dbus_setenv(), a simple wrapper around setenv().
1065 Note that this is not thread-safe. (fd.o #39196, Simon)
1067 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
1068 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
1069 (connect to a given bus, like dbus-monitor --address=ADDRESS).
1070 dbus-send --address still exists for backwards compatibility,
1071 but is no longer documented. (fd.o #48816, Andrey Mazo)
1074 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
1079 • Avoid an infinite busy-loop if a signal interrupts waitpid()
1080 (fd.o #68945, Simon McVittie)
1082 • Clean up memory for parent nodes when objects are unexported
1083 (fd.o #60176, Thomas Fitzsimmons)
1085 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
1086 documented. Previously, it assumed its second parameter was TRUE.
1087 (fd.o #69165, Chengwei Yang)
1089 • Escape addresses containing non-ASCII characters correctly
1090 (fd.o #53499, Chengwei Yang)
1092 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
1094 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
1095 (fd.o #65923, Chengwei Yang)
1097 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
1098 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
1100 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
1101 that was never va_start()ed (fd.o #66300, Chengwei Yang)
1103 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
1105 • fix a regression test on platforms with strict alignment (fd.o #67279,
1108 • Avoid calling function parameters "interface" since certain Windows headers
1109 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
1111 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
1113 • Various thread-safety improvements to static variables (fd.o #68610,
1116 • Make "make -j check" work (fd.o #68852, Simon McVittie)
1118 • Fix a NULL pointer dereference on an unlikely error path
1119 (fd.o #69327, Sviatoslav Chagaev)
1121 • Improve valgrind memory pool tracking (fd.o #69326,
1124 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
1127 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
1128 (fd.o #66107, Chengwei Yang)
1131 · If accept4() fails with EINVAL, as it can on older Linux kernels
1132 with newer glibc, try accept() instead of going into a busy-loop.
1133 (fd.o #69026, Chengwei Yang)
1134 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
1135 for instance on Hurd or older Linux with a new glibc, try without
1136 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)
1137 · Fix a file descriptor leak on an error code path.
1138 (fd.o #69182, Sviatoslav Chagaev)
1139 · dbus-run-session: clear some unwanted environment variables
1140 (fd.o #39196, Simon)
1141 · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang)
1142 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
1143 · Use dbus-launch from the builddir for testing, not the installed copy
1144 (fd.o #37849, Chengwei Yang)
1145 · Fix compilation if writev() is unavailable (fd.o #69409,
1147 · Remove broken support for LOCAL_CREDS credentials passing, and
1148 document where each credential-passing scheme is used (fd.o #60340,
1150 · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality
1151 (fd.o #35881, #69787; Chengwei Yang)
1152 · dbus-monitor: be portable to NetBSD (fd.o #69842, Chengwei Yang)
1153 · dbus-launch: stop using non-portable asprintf (fd.o #37849, Simon)
1154 · Improve error reporting from the setuid activation helper (fd.o #66728,
1158 · Remove unavailable command-line options from 'dbus-daemon --help'
1159 (fd.o #42441, Ralf Habacker)

1161 Windows XP via the undocumented AllocateAndGetTcpExTableFromStack
1162 function (fd.o #66060, Ralf Habacker)
1163 · Fix insufficient dependency-tracking (fd.o #68505, Simon McVittie)
1164 · Don't include wspiapi.h, fixing a compiler warning (fd.o #68852,

1170 · improve verbose-mode output (fd.o #63047, Colin Walters)
1171 · consolidate Autotools and CMake build (fd.o #64875, Ralf Habacker)
1172 · fix various unused variables, unusual build configurations

1179 The “but is your thread-safety thread-safe?” release.
1183 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
1184 of service for system services. Vulnerability reported by Alexandru Cornea.
1189 • The Windows version of libdbus now contains a C++ source file, used
1190 to provide global initialization when the library is loaded.
1191 gcc (mingw*) users should ensure that g++ is also installed.
1193 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
1194 and was never the recommended option) has been removed. Expat is now a
1199 • It should now be safe to call dbus_threads_init_default() from any thread,
1200 at any time. Authors of loadable modules and plugins that use libdbus
1201 should consider doing so during initialization.
1202 (fd.o #54972, Simon McVittie)
1204 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
1208 · dbus-run-session: experimental new tool to start a temporary D-Bus
1209 session, e.g. for regression tests or a text console, replacing
1210 certain uses of dbus-launch which weren't really correct
1211 (fd.o #39196, Simon)
1215 • In dbus-daemon, don't crash if a .service file starts with key=value
1216 (fd.o #60853, Chengwei Yang)
1219 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
1220 on a platform not defining LOG_PERROR, such as Solaris or QNX.
1221 This regressed in 1.7.0. (Simon)
1222 · Fix an assertion failure if we try to activate systemd services before
1223 systemd connects to the bus (fd.o #50199, Chengwei Yang)
1224 · Avoid compiler warnings for ignoring the return from write()
1228 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
1229 so that Windows finds them (fd.o #59733, Ralf Habacker)
1231 D-Bus 1.7.2 (2013-04-25)
1234 The “only partially opaque” release.
1236 Configuration changes:
1238 • On non-QNX Unix platforms, the default limit on fds per message in the
1239 session bus configuration has reduced from 4096 to 1024. The default
1240 limit used on the system bus was already 1024. On QNX, both limits are
1241 reduced further, to 128.
1245 • D-Bus Specification 0.21
1246 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,

1280 D-Bus 1.7.0 (2013-02-22)
1283 The "Disingenuous Assertions" release.
1285 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
1286 remains the recommended version for long-term-supported distributions
1287 or the upcoming GNOME 3.8 release.
1289 Build-time configuration changes:
1291 • The --with-dbus-session-bus-default-address configure option is no longer
1292 supported. Use the new --with-dbus-session-bus-connect-address and
1293 --with-dbus-session-bus-listen-address options instead. On Windows, you
1294 usually want them to have the same argument; on Unix, the defaults are
1297 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
1298 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
1299 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
1301 • cmake/cross-compile.sh has been removed. Instead, please use a
1302 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
1303 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
1304 as documented in "info automake Cross-Compilation", and set
1305 PKG_CONFIG_PATH appropriately.
1309 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
1310 • man2html is no longer used.

1316 implements o.fd.DBus (fd.o #51865, Colin Walters)
1317 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
1318 · stop claiming that all basic types work just like INT32 (strings don't!)
1320 • The "source code" for the man pages is now Docbook XML, eliminating
1321 the outdated duplicate copies used when building with CMake.
1322 (fd.o #59805; Ralf Habacker, Simon McVittie)
1326 • In the activation helper, when compiled for tests, do not reset the system
1327 bus address, fixing the regression tests. (fd.o #52202, Simon)
1329 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
1330 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
1332 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

1351 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
1354 · The default session bus listening and connecting address is now
1355 "autolaunch:", which makes D-Bus on Windows interoperate with itself
1356 and GDBus "out of the box". Use the configure options and cmake variables
1357 described above if you require a different autolaunch scope.
1358 (fd.o #38201, Simon McVittie)
1359 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
1361 • Create session.d, system.d directories under CMake (fd.o #41319,
1364 D-Bus 1.6.8 (2012-09-28)
1367 The "Fix one thing, break another" release.
1369 • Follow up to CVE-2012-3524: The additional hardening
1370 work to use __secure_getenv() as a followup to bug #52202
1371 broke certain configurations of gnome-keyring. Given
1372 the difficulty of making this work without extensive
1373 changes to gnome-keyring, use of __secure_getenv() is

1415 (fd.o #51032, Simon McVittie)
1417 • Disconnect "developer mode" (assertions, verbose mode etc.) from
1418 Automake maintainer mode. D-Bus developers should now configure with
1419 --enable-developer. Automake maintainer mode is now on by default;
1420 distributions can disable it with --disable-maintainer-mode.
1421 (fd.o #34671, Simon McVittie)
1423 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
1424 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
1427 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
1429 D-Bus 1.6.0 (2012-06-05)
1432 The “soul of this machine has improved” release.
1434 This version starts a new stable branch of D-Bus: only bug fixes will
1435 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
1437 Summary of changes since 1.4.x:

1476 Changes since 1.5.12:
1478 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
1479 spec-compliance (fd.o #48580, David Zeuthen)
1481 • Don't use install(1) within the source/build trees, fixing the build as
1482 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
1484 • Add missing commas in some tcp and nonce-tcp addresses, and remove
1485 an unused duplicate copy of the nonce-tcp transport in Windows builds
1486 (fd.o #45896, Simon McVittie)
1488 D-Bus 1.5.12 (2012-03-27)
1491 The “Big Book of Science” release.
1493 • Add public API to validate various string types:
1494 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
1495 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
1496 (fd.o #39549, Simon McVittie)
1498 • Turn DBusBasicValue into public API so bindings don't need to invent their
1499 own "union of everything" type (fd.o #11191, Simon McVittie)
1501 • Enumerate data files included in the build rather than using find(1)
1502 (fd.o #33840, Simon McVittie)

1511 (fd.o #47321, Andoni Morales Alastruey)
1513 D-Bus 1.5.10 (2012-02-21)
1516 The "fire in Delerium" release.
1518 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
1519 and SUSv2) is now required.
1521 • D-Bus Specification 0.19:
1522 · Formally define unique connection names and well-known bus names,
1523 and document best practices for interface, bus, member and error names,
1524 and object paths (fd.o #37095, Simon McVittie)
1525 · Document the search path for session and system services on Unix, and
1526 where they should be installed by build systems (fd.o #21620, fd.o #35306;
1528 · Document the systemd transport (fd.o #35232, Lennart Poettering)
1530 • Make dbus_threads_init() use the same built-in threading implementation
1531 as dbus_threads_init_default(); the user-specified primitives that it
1532 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
1534 • Allow all configured auth mechanisms, not just one (fd.o #45106,
1537 • Improve cmake build system (Ralf Habacker):
1538 · simplify XML parser dependencies (fd.o #41027)
1539 · generate build timestamp (fd.o #41029)
1540 · only create batch files on Windows
1541 · fix option and cache syntax
1542 · add help-options target
1543 · share dbus-arch-deps.h.in with autotools rather than having our
1544 own version (fd.o #41033)
1546 • Build tests successfully with older GLib, as found in e.g. Debian 6
1547 (fd.o #41219, Simon McVittie)
1549 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
1551 • Build documentation correctly if man2html doesn't support filenames on
1552 its command-line (fd.o #43875, Jack Nagel)
1554 • Improve test coverage. To get even more coverage, run the tests with
1555 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
1557 • Reduce the size of the shared library by moving functionality only used
1558 by dbus-daemon, tests etc. into their internal library and deleting
1559 unused code (fd.o #34976, #39759; Simon McVittie)
1561 • Add dbus-daemon --nopidfile option, overriding the configuration, for
1562 setups where the default configuration must include <pidfile/> to avoid
1563 breaking traditional init, but the pid file is in fact unnecessary; use
1564 it under systemd to improve startup time a bit (fd.o #45520,
1567 • Optionally (if configured --with-valgrind) add instrumentation to debug
1568 libdbus and associated tools more meaningfully under Valgrind
1569 (fd.o #37286, Simon McVittie)
1571 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
1573 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
1575 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
1576 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
1577 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
1580 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
1584 · Replace our broken reimplementation of recursive mutexes, which has
1585 been broken since 2006, with an ordinary pthreads recursive mutex
1586 (fd.o #43744; Sigmund Augdal, Simon McVittie)
1587 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
1588 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
1589 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
1590 · When running under systemd, use it instead of ConsoleKit to check
1591 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
1592 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
1593 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
1594 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
1595 (fd.o #41218, Simon McVittie)
1596 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
1597 helper doesn't obey environment variables to avoid privilege escalation
1598 attacks, so make the system bus follow the same rules
1599 (fd.o #21620, Simon McVittie)
1602 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
1603 Jesper Dam, Ralf Habacker)
1604 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
1607 D-Bus 1.5.8 (2011-09-21)

1612 In addition to dead code removal and refactoring, this release contains all
1613 of the bugfixes from 1.4.16.
1615 • Clean up dead code, and make more warnings fatal in development builds
1616 (fd.o #39231, fd.o #41012; Simon McVittie)
1618 • If full test coverage is requested via --enable-tests, strictly require
1619 Python, pygobject and dbus-python, which are required by some tests; if not,
1620 and Python is missing, skip those tests rather than failing
1621 (fd.o #37847, Simon McVittie)
1623 • When using cmake, provide the same version-info API in the installed headers
1624 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
1626 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
1628 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
1630 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
1633 • Fix duplicates in authors list (Ralf Habacker)
1635 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
1636 (fd.o #39879, Chris Mayo)
1638 • Fix a small memory leak, and a failure to report errors, when updating
1639 a service file entry for activation (fd.o #39230, Simon McVittie)
1642 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
1643 Brian Cameron, Simon McVittie)
1644 · On systems that use libcap-ng but not systemd, drop supplemental groups
1645 when switching to the daemon user (Red Hat #726953, Steve Grubb)
1646 · Make the cmake build work again on GNU platforms (fd.o #29228,
1648 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
1649 like Solaris (fd.o #40313, Dagobert Michelsen)
1650 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
1651 (fd.o #40235, Simon McVittie)
1652 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
1653 (fd.o #39987, Simon McVittie)
1654 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
1655 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
1658 · Fix compilation on MSVC, which doesn't understand "inline" with its
1659 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
1660 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)

1663 D-Bus 1.5.6 (2011-07-29)
1666 The "weird, gravy-like aftertaste" release.
1668 In addition to new features and refactoring, this release contains all of the
1669 bugfixes from 1.4.14.
1671 Potentially incompatible (Bustle and similar debugging tools will need
1672 changes to work as intended):
1674 • Do not allow match rules to "eavesdrop" (receive messages intended for a
1675 different recipient) by mistake: eavesdroppers must now opt-in to this
1676 behaviour by putting "eavesdrop='true'" in the match rule, which will
1677 not have any practical effect on buses where eavesdropping is not allowed
1678 (fd.o #37890, Cosimo Alfarano)
1682 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
1683 Cosimo Alfarano, Simon McVittie)
1684 · add the "eavesdrop" keyword to match rules
1685 · define eavesdropping, unicast messages and broadcast messages
1686 · stop claiming that match rules are needed to match unicast messages to you
1687 · promote the type system to be a top-level section
1689 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
1690 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
1691 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
1693 • Consistently use atomic operations on everything that is ever manipulated
1694 via atomic ops, as was done for changes to DBusConnection's refcount in
1695 1.4.12 (fd.o #38005, Simon McVittie)
1697 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
1700 • Make "make check" in a clean tree work, by not running tests until
1701 test data has been set up (fd.o #34405, Simon McVittie)
1703 • The dbus-daemon no longer busy-loops if it has a very large number of file
1704 descriptors (fd.o #23194, Simon McVittie)
1706 • Refactor message flow through dispatching to avoid locking violations if
1707 the bus daemon's message limit is hit; remove the per-connection link cache,
1708 which was meant to improve performance, but now reduces it (fd.o #34393,
1711 • Some cmake fixes (Ralf Habacker)
1713 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
1714 Simon McVittie, Lennart Poettering)
1716 • Stop storing two extra byte order indicators in each D-Bus message
1717 (fd.o #38287, Simon McVittie)
1719 • Add an optional Stats interface which can be used to get statistics from
1720 a running dbus-daemon if enabled at configure time with --enable-stats
1721 (fd.o #34040, Simon McVittie)
1723 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
1725 • Documentation (fd.o #36156, Simon McVittie):
1726 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
1727 · install more documentation automatically, including man2html output
1728 · put dbus.devhelp in the right place (it must go in ${htmldir})
1731 · look for system services in /lib/dbus-1/system-services in addition to all
1732 the other well-known locations; note that this should always be /lib,
1733 even on platforms where shared libraries on the root FS would go in /lib64,
1734 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
1735 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
1737 • Windows-specific (Ralf Habacker):
1738 · fix use of a mutex for autolaunch server detection
1739 · don't crash on malloc failure in _dbus_printf_string_upper_bound
1741 D-Bus 1.5.4 (2011-06-10)
1744 Security (local denial of service):
1746 • Byte-swap foreign-endian messages correctly, preventing a long-standing
1747 local DoS if foreign-endian messages are relayed through the dbus-daemon
1748 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
1749 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
1753 • The constant to use for an infinite timeout now has a name,
1754 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
1755 which can be used for source compatibility with older versions of libdbus.
1757 • If GLib and DBus-GLib are already installed, more tests will be built,
1758 providing better coverage. The new tests can also be installed via
1759 ./configure --enable-installed-tests
1760 for system integration testing, if required. (fd.o #34570, Simon McVittie)
1764 • Consistently use atomic operations for the DBusConnection's refcount,
1765 fixing potential threading problems (fd.o #38005, Simon McVittie)
1767 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
1768 small (300KiB on x86-64) and it frequently doesn't work in unusual
1769 toolchains. To optimize for minimum installed size, you should benchmark
1770 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
1771 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
1773 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
1774 (fd.o #35880, Timothy Redaelli)
1776 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
1777 when not using a DESTDIR (fd.o #37870, Simon McVittie)
1779 • Windows-specific changes:
1780 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
1782 D-Bus 1.5.2 (2011-06-01)
1785 The "Boar Hunter" release.
1787 Notes for distributors:
1789 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
1790 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
1791 toolchain supports it reliably, via something like:
1793 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
1795 or by using distribution-specific wrappers such as Debian's hardening-wrapper.

1806 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
1807 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
1808 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
1809 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)

1819 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
1820 (fd.o #35228, Lennart Poettering)
1821 • In the regression tests, don't report fds as "leaked" if they were open
1822 on startup (fd.o #35173, Simon McVittie)

1846 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
1848 • Require user intervention to compile with missing 64-bit support
1849 (fd.o #35114, Simon McVittie)
1850 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)

1858 The "It's like the beginning of a lobster" release.
1860 • Rename configure.in to configure.ac, and update it to modern conventions
1861 (fd.o #32245; Javier Jardón, Simon McVittie)
1862 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
1864 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
1865 --disable-x11-autolaunch configure option to prevent it altogether
1866 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
1867 • Install the documentation, and an index for Devhelp (fd.o #13495,
1868 Debian #454142; Simon McVittie, Matthias Clasen)
1869 • If checks are not disabled, check validity of string-like types and
1870 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
1871 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
1872 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
1873 • Break up a huge conditional in config-parser so gcov can produce coverage
1874 data (fd.o #10887, Simon McVittie)
1875 • List which parts of the Desktop Entry specification are applicable to
1876 .service files (fd.o #19159, Sven Herzberg)

1891 which were mistakenly included in 1.4.4
1893 D-Bus 1.4.4 (2010-02-17)
1896 • Switch back to using even micro versions for stable releases; 1.4.1
1897 should have been called 1.4.2, so skip that version number
1898 • Don't leave bad file descriptors being watched when spawning processes,
1899 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
1900 also LP#656134, LP#680444, LP#713157)
1901 • Check for MSG_NOSIGNAL correctly
