1 D-Bus 1.10.6 (2015-12-01)
4 The “marzipan beetles” release.
8 • On Unix when running tests as root, don't assert that root and
9 the dbus-daemon user can still call UpdateActivationEnvironment;
10 assert that those privileged users can call BecomeMonitor instead
11 (fd.o #93036, Simon McVittie)
13 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
16 • On Windows Autotools builds, don't run tests that rely on
17 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
19 D-Bus 1.10.4 (2015-11-17)
22 The “Frostburn Canyon” release.
26 • GetConnectionCredentials, GetConnectionUnixUser and
27 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
28 will now return details of the dbus-daemon itself. This is required
29 to be able to call SetEnvironment on systemd.
30 (fd.o #92857, Jan Alexander Steffens)
34 • Make UpdateActivationEnvironment always fail with AccessDenied on the
35 system bus. Previously, it was possible to configure it so root could
36 call it, but the environment variables were not actually used,
37 because the launch helper would discard them.
38 (fd.o #92857, Jan Alexander Steffens)
40 • On Unix with --systemd-activation on a user bus, make
41 UpdateActivationEnvironment pass on its arguments to systemd's
42 SetEnvironment method, solving inconsistency between the environments
43 used for traditional activation and systemd user-service activation.
44 (fd.o #92857, Jan Alexander Steffens)
46 • On Windows, don't crash if <syslog/> or --syslog is used
47 (fd.o #92538, Ralf Habacker)
49 • On Windows, fix a memory leak when setting a DBusError from a Windows
50 error (fd.o #92721, Ralf Habacker)
52 • On Windows, don't go into infinite recursion if we abort the process
53 with backtraces enabled (fd.o #92721, Ralf Habacker)
55 • Fix various failing tests, variously on Windows and cross-platform:
56 · don't test system.conf features (users, groups) that only make sense
57 on the system bus, which is not supported on Windows
58 · don't call _dbus_warn() when we skip a test, since it is fatal
59 · fix computation of expected <standard_session_servicedirs/>
60 · when running TAP tests, translate newlines to Unix format, fixing
61 cross-compiled tests under Wine on Linux
62 · don't stress-test refcounting under Wine, where it's really slow
63 · stop assuming that a message looped-back to the test will be received
65 · skip some system bus tests on Windows since they make no sense there
66 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
68 D-Bus 1.10.2 (2015-10-26)
71 The “worst pies in London” release.
75 • Correct error handling for activation: if there are multiple attempts
76 to activate the same service and it fails immediately, the first attempt
77 would get the correct reply, but the rest would time out. We now send
78 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
80 • If BecomeMonitor is called with a syntactically invalid match rule,
81 don't crash with an assertion failure, fixing a regression in 1.9.10.
82 This was not exploitable as a denial of service, because the check
83 for a privileged user is done first. (fd.o #92298, Simon McVittie)
85 • On Linux with --enable-user-session, add the bus address to the
86 environment of systemd services for better backwards compatibility
87 (fd.o #92612, Jan Alexander Steffens)
89 • On Windows, fix the logic for replacing the installation prefix
90 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
92 • On Windows, if installed in the conventional layout with ${prefix}/etc
93 and ${prefix}/share, use relative paths between bus configuration files
94 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
96 • Make more of the regression tests pass in Windows builds (fd.o #92538,
99 D-Bus 1.10.0 (2015-08-25)
104 This is a new stable branch, recommended for use in OS distributions.
108 • distribute test/tap-test.sh.in, even if the tarball was built without
109 tests enabled (fd.o #91684, Simon McVittie)
110 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
112 Summary of major changes since 1.8.0:
114 • The basic setup for the well-known system and session buses is
115 now done in read-only files in ${datadir} (normally /usr/share).
116 See the NEWS entry for 1.9.18 for details.
118 • AppArmor integration has been merged, with features similar to the
119 pre-existing SELinux integration. It is mostly compatible with the
120 patches previously shipped by Ubuntu, with one significant change:
121 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
122 by GetConnectionCredentials and was not included.
124 • The --enable-user-session configure option can be enabled
125 by OS integrators intending to use systemd to provide a session bus
126 per user (in effect, treating all concurrent graphical and non-graphical
127 login sessions as one large session).
129 • The new listenable address mode "unix:runtime=yes" listens on
130 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
131 user session. libdbus and "dbus-launch --autolaunch" will connect to
132 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
135 • All executables are now dynamically linked to libdbus-1.
136 Previously, some executables, most notably dbus-daemon, were statically
137 linked to a specially-compiled variant of libdbus. This results in
138 various private functions in the _dbus namespace being exposed by the
139 shared library. These are not API, and must not be used outside
140 the dbus source tree.
142 • On platforms with ELF symbol versioning, all public symbols
143 are versioned LIBDBUS_1_3.
147 • org.freedesktop.DBus.GetConnectionCredentials returns
148 LinuxSecurityLabel where supported
149 • org.freedesktop.DBus.Monitoring interface (privileged)
150 · BecomeMonitor method supersedes match rules with eavesdrop=true,
151 which are now deprecated
152 • org.freedesktop.DBus.Stats interface (semi-privileged)
153 · now enabled by default
154 · new GetAllMatchRules method
155 • org.freedesktop.DBus.Verbose interface (not normally compiled)
156 · toggles the effect of DBUS_VERBOSE
161 • dbus-update-activation-environment
163 New optional dependencies:
165 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
166 • Complete documentation requires Ducktype and yelp-tools
167 • Full test coverage requires GLib 2.36 and PyGI
168 • AppArmor integration requires libapparmor and optionally libaudit
170 Dependencies removed:
174 D-Bus 1.9.20 (2015-08-06)
177 The “Remember Tomorrow” release.
179 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
184 • Don't second-guess what the ABI of poll() is, allowing it to be used
185 on Integrity RTOS and other unusual platforms (fd.o #90314;
186 Rolland Dudemaine, Simon McVittie)
188 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
189 both enabled (fd.o #89225, Simon McVittie)
191 • Log audit events for AppArmor/SELinux policy violations whenever
192 we have CAP_AUDIT_WRITE, even if not the system bus
193 (fd.o #83856, Laurent Bigonville)
195 D-Bus 1.9.18 (2015-07-21)
198 The “Pirate Elite” release.
200 Configuration changes:
202 • The basic setup for the well-known system and session buses is now done
203 in read-only files in ${datadir}, moving a step closer to systems
204 that can operate with an empty /etc directory. In increasing order
207 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
208 the default message policies.
209 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
210 dbus still installs a trivial version of each, for documentation
211 purposes; putting configuration directives in these files is deprecated.
212 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
213 to install "drop-in" configuration snippets (any packages
214 using those directories should explicitly depend on at least this
216 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
217 or third-party software to install "drop-in" configuration snippets
218 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
221 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
222 and "s*" refers to either system or session as appropriate.
224 (fd.o #89280, Dimitri John Ledkov)
228 • Fix a memory leak when GetConnectionCredentials() succeeds
229 (fd.o #91008, Jacek Bukarewicz)
231 • Ensure that dbus-monitor does not reply to messages intended for others,
232 resulting in its own disconnection (fd.o #90952, Simon McVittie)
234 D-Bus 1.9.16 (2015-05-14)
237 The “titanium barns” release.
241 • Automake 1.13 is now required when compiling from git or modifying
246 • On Unix platforms, change the default configuration for the session bus
247 to only allow EXTERNAL authentication (secure kernel-mediated
248 credentials-passing), as was already done for the system bus.
250 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
251 unpredictable pseudo-random numbers.
253 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
254 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
255 NFS or similar, you will need to reconfigure the session bus to accept
256 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
259 (fd.o #90414, Simon McVittie)
261 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
262 transport, UUIDs or any other reason, fail if we cannot obtain entropy
263 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
264 occurs, instead of silently falling back to low-entropy pseudorandom
265 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
269 • Add dbus_message_iter_get_element_count()
270 (fd.o #30350; Christian Dywan, Simon McVittie)
272 • Introduce new internal DBusSocket and DBusPollable types so we can
273 stop treating the Windows SOCKET type as if it was int. DBusSocket
274 is specifically a socket, cross-platform. DBusPollable is whatever
275 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
276 (fd.o #89444; Ralf Habacker, Simon McVittie)
278 • All regression tests now output TAP <https://testanything.org/>
279 (fd.o #89846, Simon McVittie)
281 • Internal APIs consistently use signed values for timestamps
282 (fd.o #18494, Peter McCurdy)
284 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
285 (fd.o #88812, Simon McVittie)
287 • Clean up a lot of compiler warnings
288 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
292 • Add locking to DBusCounter's reference count and notify function
293 (fd.o #89297, Adrian Szyndela)
295 • Ensure that DBusTransport's reference count is protected by the
296 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
298 • Correctly release DBusServer mutex before early-return if we run out
299 of memory while copying authentication mechanisms (fd.o #90021,
302 • Make dbus-test-tool and dbus-update-activation-environment portable
303 to Windows (fd.o #90089, Ralf Habacker)
305 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
306 Ralf Habacker, Simon McVittie)
308 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
311 • Clean up some memory and fd leaks in test code and tools
312 (fd.o #90021, Ralf Habacker)
314 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
315 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
317 • CMake generates a versioned shared library even if the revision is 0,
318 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
320 D-Bus 1.9.14 (2015-03-02)
323 The “don't stand in the poison cloud” release.
327 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
328 were previously linked to a static version of libdbus.
330 • The tests no longer require dbus-glib in order to exercise the libdbus
331 shared library; they are always linked to libdbus now.
333 Build-time configuration:
335 • The new --enable-user-session option, off by default, can be enabled
336 by OS integrators intending to use systemd to provide a session bus
337 per user (in effect, treating all concurrent graphical and non-graphical
338 login sessions as one large session)
342 • All executables are now linked dynamically to libdbus.
343 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
345 • On platforms that support them (GNU libc and possibly others),
346 libdbus now has versioned symbols for its public API.
347 All public symbols (visible in the header files) are currently
348 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
349 dbus_internal have a version that changes with each release, and
350 must not be used by applications. (also fd.o #83115)
352 • New listenable address mode "unix:runtime=yes" which listens on
353 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
354 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
356 • Add optional systemd units for a per-user bus listening on
357 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
359 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
360 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
363 • New dbus-update-activation-environment tool uploads environment
364 variables to "dbus-daemon --session" and optionally "systemd --user",
365 primarily as a way to keep the per-user bus compatible with
366 distributions' existing X11 login scripts (also fd.o #61301)
368 • <includedir/> elements in dbus-daemon configuration are now silently
369 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
371 • Add microsecond-resolution timestamps to the default output of
372 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
376 • Fix a race condition in the 'monitor' test introduced in 1.9.10
377 (fd.o #89222, Simon McVittie)
379 D-Bus 1.9.12 (2015-02-19)
382 The “monster lasagna” release.
386 • Ducktype and yelp-tools are now required to build complete documentation
387 (they are optional for normal builds).
391 • D-Bus Specification version 0.26
392 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
393 · document the BecomeMonitor method
395 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
396 (fd.o #89041; Tyler Hicks, Simon McVittie)
398 • On Linux, add support for AppArmor mediation of message sending and
399 receiving and name ownership (paralleling existing SELinux mediation
400 support), and eavesdropping (a new check, currently AppArmor-specific)
401 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
403 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
404 that have printable ASCII contents; we previously only did this for
405 unterminated bytestrings (fd.o #89109, Simon McVittie)
407 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
409 • On Windows, add WindowsSID to GetConnectionCredentials
410 (fd.o #54445, Ralf Habacker)
412 • Improve clarity of dbus-monitor --profile output and add more columns
413 (fd.o #89165, Ralf Habacker)
415 • Add a man page for dbus-test-tool, and build it under CMake as well
416 as Autotools (fd.o#89086, Simon McVittie)
418 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
419 to control it at runtime, overriding the DBUS_VERBOSE environment variable
420 (fd.o #88896, Ralf Habacker)
424 • Reduce the number of file descriptors used in the fd-passing test,
425 avoiding failure under the default Linux fd limit, and automatically
426 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
428 D-Bus 1.9.10 (2015-02-09)
431 The “sad cyborgs” release.
433 Security fixes merged from 1.8.16:
435 • Do not allow non-uid-0 processes to send forged ActivationFailure
436 messages. On Linux systems with systemd activation, this would
437 allow a local denial of service: unprivileged processes could
438 flood the bus with these forged messages, winning the race with
439 the actual service activation and causing an error reply
440 to be sent back when service auto-activation was requested.
441 This does not prevent the real service from being started,
442 so the attack only works while the real service is not running.
443 (CVE-2015-0245, fd.o #88811; Simon McVittie)
447 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
448 similar tools receive messages without altering the security properties
449 of the system bus, by calling the new BecomeMonitor method on a
450 private connection. This bypasses the normal <allow> and <deny> rules
451 entirely, so to preserve normal message-privacy assumptions, only root
452 is allowed to do this on the system bus. Restricted environments,
453 such as Linux with LSMs, should lock down access to the Monitoring
454 interface. (fd.o #46787, Simon McVittie)
456 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
457 dbus-daemon supports it and access permissions allow it.
458 It still supports the previous approach ("eavesdropping" match rules)
459 for compatibility with older bus daemons. (fd.o #46787, Simon)
461 • dbus-monitor can now log the message stream as binary data for later
462 analysis, with either no extra framing beyond the normal D-Bus headers,
463 or libpcap-compatible framing treating each D-Bus message
464 as a captured packet. (fd.o #46787, Simon)
468 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
470 • On Unix, forcibly terminate regression tests after 60 seconds to
471 prevent them from blocking continuous integration frameworks
474 D-Bus 1.9.8 (2015-02-03)
477 The “all the types of precipitation” release.
481 • full test coverage now requires GLib 2.36
482 • full test coverage now requires PyGI (PyGObject 3,
483 "import gi.repository.GObject") instead of the
484 obsolete PyGObject 2 ("import gobject")
488 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
490 • better regression test coverage, including systemd activation
491 (fd.o #57952, #88810; Simon McVittie)
495 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
496 turned off (fd.o #88808, Simon McVittie)
498 • TCP sockets on Windows no longer fail to listen approximately 1 time
499 in 256, caused by a logic error that should have always made it fail but
500 was mitigated by incorrect endianness for the port number
501 (fd.o #87999, Ralf Habacker)
503 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
505 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
506 previous 64, completing a previous fix which only worked under
507 Autotools (fd.o #71297, Ralf Habacker)
509 • on Windows, if the IP family is unspecified only use IPv4,
510 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
512 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
514 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
516 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
519 D-Bus 1.9.6 (2015-01-05)
522 The “I do have a bread knife” release.
526 • Do not allow calls to UpdateActivationEnvironment from uids other than
527 the uid of the dbus-daemon. If a system service installs unsafe
528 security policy rules that allow arbitrary method calls
529 (such as CVE-2014-8148) then this prevents memory consumption and
530 possible privilege escalation via UpdateActivationEnvironment.
532 We believe that in practice, privilege escalation here is avoided
533 by dbus-daemon-launch-helper sanitizing its environment; but
534 it seems better to be safe.
536 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
537 on object paths other than /org/freedesktop/DBus. Some system services
538 install unsafe security policy rules that allow arbitrary method calls
539 to any destination, method and interface with a specified object path;
540 while less bad than allowing arbitrary method calls, these security
541 policies are still harmful, since dbus-daemon normally offers the
542 same API on all object paths and other system services might behave
547 • Add missing initialization so GetExtendedTcpTable doesn't crash on
548 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
550 D-Bus 1.9.4 (2014-11-24)
553 The “extra-sturdy caramel” release.
557 • Partially revert the CVE-2014-3639 patch by increasing the default
558 authentication timeout on the system bus from 5 seconds back to 30
559 seconds, since this has been reported to cause boot regressions for
560 some users, mostly with parallel boot (systemd) on slower hardware.
562 On fast systems where local users are considered particularly hostile,
563 administrators can return to the 5 second timeout (or any other value
564 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
567 <limit name="auth_timeout">5000</limit>
570 (fd.o #86431, Simon McVittie)
572 • Add a message in syslog/the Journal when the auth_timeout is exceeded
573 (fd.o #86431, Simon McVittie)
575 • Send back an AccessDenied error if the addressed recipient is not allowed
576 to receive a message (and in builds with assertions enabled, don't
577 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
579 D-Bus 1.9.2 (2014-11-10)
582 The “structurally unsound flapjack” release.
586 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
587 so that CVE-2014-3636 part A cannot exhaust the system bus'
588 file descriptors, completing the incomplete fix in 1.8.8.
589 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
593 • D-Bus Specification version 0.25
594 · new value 'const' for EmitsChangedSignal annotation
595 (fd.o #72958, Lennart Poettering)
596 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
597 (fd.o #83449; Lennart Poettering, Simon McVittie)
598 · annotate table of types with reserved/basic/container, and for
599 basic types, fixed/string-like
600 · clarify arbitrary limits by quoting them in mebibytes
602 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
603 (fd.o #83449, Simon McVittie)
605 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
606 useful for debugging and performance testing:
607 · dbus-test-tool spam: send repeated messages
608 · dbus-test-tool echo: send an empty reply for all method calls
609 · dbus-test-tool black-hole: do not reply to method calls
610 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
612 • Add support for process ID in credentials-passing on NetBSD
613 (fd.o #69702, Patrick Welche)
615 • Add an example script to find potentially undesired match rules
616 (fd.o #84598, Alban Crequy)
618 • Document the central assumption that makes our use of credentials-passing
619 secure (fd.o #83499, Simon McVittie)
621 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
622 and add some links to GDBus and QtDBus documentation (fd.o #25140,
627 • Use a less confusing NoReply message when disconnected with a reply pending
628 (fd.o #76112, Simon McVittie)
630 • Make the .pc file relocatable by letting pkg-config do all variable
631 expansion itself (fd.o #75858, Руслан Ижбулатов)
633 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
634 (fd.o #85563, Patrick Welche)
636 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
638 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
639 do not lose the exec() errno (fd.o #24821, Simon McVittie)
641 • Do not fail the tests if a parent process has leaked non-close-on-exec
642 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
644 • Do not fail the tests on Unix platforms with incomplete
645 credentials-passing support, but do fail if we can't pass credentials
646 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
647 (fd.o #69702, Simon McVittie)
649 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
650 when building with cmake, and expand test coverage there
651 (fd.o #73689; Ralf Habacker, Simon McVittie)
653 D-Bus 1.9.0 (2014-10-01)
656 The “tiered cheeses” release.
660 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
661 requires either the libsystemd or libsd-daemon shared library, dropping the
662 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
664 Build-time configuration changes:
666 • The Stats interface is now enabled by default, and locked-down to
667 root-only on the system bus. Configure with --disable-stats
668 to disable it altogether on memory- or disk-constrained systems,
669 or see ${docdir}/examples/ to open it up to non-root users on the
670 system bus or restrict access on the session bus.
671 (fd.o #80759; Simon McVittie, Alban Crequy)
673 • The CMake build system now builds the same shared library name as Autotools
674 on at least Linux and Windows:
675 - on Linux (and perhaps other Unix platforms), it previously built
676 libdbus-1.so, but now builds libdbus-1.so.3.* with development
677 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
678 - on Windows, it previously built either libdbus-1.dll (release) or
679 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
680 libdbus-1.dll for compatibility with older applications.
681 (fd.o #74117, Ralf Habacker)
685 • D-Bus Specification version 0.24
686 · document how to quote match rules (fd.o #24307, Simon McVittie)
687 · explicitly say that most message types never expect a reply
688 regardles of whether they have NO_REPLY_EXPECTED
689 (fd.o #75749, Simon McVittie)
691 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
692 initial latency (fd.o #75544, Matt Hoosier)
694 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
695 (fd.o #69702, Patrick Welche)
697 • in dbus-monitor, print more information about file descriptors
698 (fd.o #80603, Alban Crequy)
700 • do not install system bus configuration if built for Windows
701 (fd.o #83583; Ralf Habacker, Simon McVittie)
703 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
705 • Add a regression test for file descriptor passing (fd.o #83622,
710 • fix an incorrect error message if a Unix socket path is too long
711 (fd.o #73887, Antoine Jacoutot)
713 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
714 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
716 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
717 in ps(1) (fd.o #69716, Chengwei Yang)
719 • avoid calling poll() with timeout < -1, which is considered invalid
720 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
722 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
723 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
724 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
726 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
728 • Documentation improvements
729 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
731 • in dbus-monitor, do not leak file descriptors that we have monitored
732 (fd.o #80603, Alban Crequy)
734 • Set the close-on-exec flag for the inotify file descriptor, even
735 if built with CMake or older libc (fd.o #73689, Simon McVittie)
737 • Remove some LGPL code from the Windows dbus-daemon
738 (fd.o #57272, Ralf Habacker)
740 D-Bus 1.8.8 (2014-09-16)
743 The "smashy smashy egg man" release.
747 • Do not accept an extra fd in the padding of a cmsg message, which
748 could lead to a 4-byte heap buffer overrun.
749 (CVE-2014-3635, fd.o #83622; Simon McVittie)
751 • Reduce default for maximum Unix file descriptors passed per message
752 from 1024 to 16, preventing a uid with the default maximum number of
753 connections from exhausting the system bus' file descriptors under
754 Linux's default rlimit. Distributors or system administrators with a
755 more restrictive fd limit may wish to reduce these limits further.
757 Additionally, on Linux this prevents a second denial of service
758 in which the dbus-daemon can be made to exceed the maximum number
759 of fds per sendmsg() and disconnect the process that would have
761 (CVE-2014-3636, fd.o #82820; Alban Crequy)
763 • Disconnect connections that still have a fd pending unmarshalling after
764 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
765 removing the possibility of creating an abusive connection that cannot be
766 disconnected by setting up a circular reference to a connection's
768 (CVE-2014-3637, fd.o #80559; Alban Crequy)
770 • Reduce default for maximum pending replies per connection from 8192 to 128,
771 mitigating an algorithmic complexity denial-of-service attack
772 (CVE-2014-3638, fd.o #81053; Alban Crequy)
774 • Reduce default for authentication timeout on the system bus from
775 30 seconds to 5 seconds, avoiding denial of service by using up
776 all unauthenticated connection slots; and when all unauthenticated
777 connection slots are used up, make new connection attempts block
778 instead of disconnecting them.
779 (CVE-2014-3639, fd.o #80919; Alban Crequy)
783 • Check for libsystemd from systemd >= 209, falling back to
784 the older separate libraries if not found (Umut Tezduyar Lindskog,
787 • On Linux, use prctl() to disable core dumps from a test executable
788 that deliberately raises SIGSEGV to test dbus-daemon's handling
789 of that condition (fd.o #83772, Simon McVittie)
791 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
794 • Improve documentation for running tests on Windows (fd.o #41252,
797 D-Bus 1.8.6 (2014-06-02)
802 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
803 the message. This prevents an attack in which a malicious client can
804 make dbus-daemon disconnect a system service, which is a local
806 (fd.o #80163, CVE-2014-3532; Alban Crequy)
808 • Track remaining Unix file descriptors correctly when more than one
809 message in quick succession contains fds. This prevents another attack
810 in which a malicious client can make dbus-daemon disconnect a system
812 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
813 Simon McVittie, Alban Crequy)
817 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
818 attach to a session, kill the dbus-daemon as intended
819 (fd.o #74698, Роман Донченко)
821 D-Bus 1.8.4 (2014-06-10)
826 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
827 flaw in dbus-daemon, part of the reference implementation of D-Bus.
828 Additionally, in highly unusual environments the same flaw could lead to
829 a side channel between processes that should not be able to communicate.
830 (CVE-2014-3477, fd.o #78979)
832 D-Bus 1.8.2 (2014-04-30)
835 The “nobody wants red” release.
839 • in the CMake build system, add some hints for Linux users cross-compiling
840 Windows D-Bus binaries to be able to run tests under Wine
841 (fd.o #41252, Ralf Habacker)
843 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
847 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
848 to /var/lib/dbus/machine-id instead of generating an entirely new ID
849 (fd.o #77941, Simon McVittie)
851 • if dbus-launch receives an X error very quickly, do not kill
852 unrelated processes (fd.o #74698, Роман Донченко)
854 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
855 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
857 • cope with \r\n newlines in regression tests, since on Windows,
858 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
860 D-Bus 1.8.0 (2014-01-20)
863 The “Wolverine distrusts my printer” release.
865 This starts a new stable branch. The 1.6.x branch is now considered to be
866 outdated, and will only receive fixes for serious bugs such as security
867 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
868 are unlikely to get any more releases, but if distributors still need to
869 support them, please share security patches via upstream.
871 Summary of changes since 1.6.x:
873 • libdbus always behaves as if dbus_threads_init_default() had been called
874 (thread-safety by default)
875 • new dbus-run-session tool, replacing certain misuses of dbus-launch
876 • dbus-monitor can talk to outdated versions of dbus-daemon again
877 • new org.freedesktop.DBus.GetConnectionCredentials method
878 • GetConnectionUnixProcessID also works correctly on Windows, returning
879 the Windows process ID
880 • GetConnectionWindowsSID returns the correct SID on Windows
881 • expat is required, libxml2 can no longer be used as a substitute
882 • the userDB cache is required, and cannot be disabled
883 • a 64-bit integer type (either int, long, long long or _int64) is required
884 • better systemd-journald integration on Linux
885 • fixed long-standing fd and array leaks when failing to parse a message
886 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
887 when using certain object-path allocation patterns, notably in Avahi
888 • better defaults for Windows support
889 • better CMake support
890 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
891 • the source language for the man pages is now Docbook XML
893 Enhancements since 1.7.10:
895 • Enhance the CMake build system to check for GLib and compile/run
896 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
900 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
903 • fix compilation of systemd journal support on older systemd versions where
904 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
906 • fix compilation on older MSVC versions by including stdlib.h
907 (fd.o #73455, Ralf Habacker)
909 • Allow <allow_anonymous/> to appear in an included configuration file
910 (fd.o #73475, Matt Hoosier)
912 Test behaviour changes since 1.7.10:
914 • If the tests crash with an assertion failure, they no longer default to
915 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
916 environment if you want the old behaviour.
918 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
919 can be run with an external dbus-daemon by setting
920 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
921 an unusually-configured dbus-daemon are skipped.
923 D-Bus 1.7.10 (2014-01-06)
926 The “weighted companion cube” release.
928 This is a release candidate for D-Bus 1.8.
930 D-Bus Specification 0.23:
932 • don't require messages with no INTERFACE to be dispatched
933 (fd.o #68597, Simon McVittie)
935 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
938 • define "listenable" and "connectable" addresses, and discuss
939 the difference (fd.o #61303, Simon McVittie)
943 • support printing Unix file descriptors in dbus-send, dbus-monitor
944 (fd.o #70592, Robert Ancell)
946 • don't install systemd units if --disable-systemd is given
947 (fd.o #71818, Chengwei Yang)
951 • don't leak memory on out-of-memory while listing activatable or
952 active services (fd.o #71526, Radoslaw Pajak)
954 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
956 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
958 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
959 and DBUS__SEND_MSG are numerically equal to their values in the
960 reference policy (fd.o #88719, osmond sun)
962 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
963 (fd.o #71366, Matt Fischer)
965 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
966 winsock2.h (fd.o #71405, Matt Fischer)
968 • do not return failure from _dbus_read_nonce() with no error set,
969 preventing a potential crash (fd.o #72298, Chengwei Yang)
971 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
972 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
974 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
975 which doesn't do anything anyway on at least Linux and FreeBSD
976 (fd.o #69492, Simon McVittie)
978 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
979 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
980 for credentials more correctly (fd.o #69492, Simon McVittie)
982 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
983 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
986 • refresh cached policy rules for existing connections when bus
987 configuration changes (fd.o #39463, Chengwei Yang)
989 D-Bus 1.7.8 (2013-11-01)
992 The “extreme hills” release.
996 • If systemd support is enabled, libsystemd-journal is now required.
1000 • When activating a non-systemd service under systemd, annotate its
1001 stdout/stderr with its bus name in the Journal. Known limitation:
1002 because the socket is opened before forking, the process will still be
1003 logged as if it had dbus-daemon's process ID and user ID.
1004 (fd.o #68559, Chengwei Yang)
1006 • Document more configuration elements in dbus-daemon(1)
1007 (fd.o #69125, Chengwei Yang)
1011 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
1012 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
1014 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
1015 disallowed method calls to the audit log, fixing a regression in 1.7.6
1016 (fd.o #49062, Colin Walters)
1018 • path_namespace='/' in match rules incorrectly matched nothing; it
1019 now matches everything. (fd.o #70799, Simon McVittie)
1021 D-Bus 1.7.6 (2013-10-09)
1024 The “CSI Shrewsbury” release.
1026 Build-time configuration changes:
1028 • Directory change notification via dnotify on Linux is no longer
1029 supported; it hadn't compiled successfully since 2010 in any case.
1030 If you don't have inotify (Linux) or kqueue (*BSD), you will need
1031 to send SIGHUP to the dbus-daemon when its configuration changes.
1032 (fd.o #33001, Chengwei Yang)
1034 • Compiling with --disable-userdb-cache is no longer supported;
1035 it didn't work since at least 2008, and would lead to an extremely
1036 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
1039 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
1040 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
1041 with the Autotools build system. (fd.o #66142, Chengwei Yang)
1043 • --with-valgrind=auto enables Valgrind instrumentation if and only if
1044 valgrind headers are available. The default is still --with-valgrind=no.
1045 (fd.o #56925, Simon McVittie)
1049 • Platforms with no 64-bit integer type are no longer supported.
1050 (fd.o #65429, Simon McVittie)
1052 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
1054 • Full test coverage no longer requires dbus-glib, although the tests do not
1055 exercise the shared library (only a static copy) if dbus-glib is missing.
1056 (fd.o #68852, Simon McVittie)
1060 • D-Bus Specification 0.22
1061 · Document GetAdtAuditSessionData() and
1062 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
1063 · Fix example .service file (fd.o #66481, Chengwei Yang)
1064 · Don't claim D-Bus is "low-latency" (lower than what?), just
1065 give factual statements about it supporting async use
1066 (fd.o #65141, Justin Lee)
1067 · Document the contents of .service files, and the fact that
1068 system services' filenames are constrained
1069 (fd.o #66608; Simon McVittie, Chengwei Yang)
1071 • Be thread-safe by default on all platforms, even if
1072 dbus_threads_init_default() has not been called. For compatibility with
1073 older libdbus, library users should continue to call
1074 dbus_threads_init_default(): it is harmless to do so.
1075 (fd.o #54972, Simon McVittie)
1077 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
1079 • New API: dbus_setenv(), a simple wrapper around setenv().
1080 Note that this is not thread-safe. (fd.o #39196, Simon)
1082 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
1083 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
1084 (connect to a given bus, like dbus-monitor --address=ADDRESS).
1085 dbus-send --address still exists for backwards compatibility,
1086 but is no longer documented. (fd.o #48816, Andrey Mazo)
1089 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
1094 • Avoid an infinite busy-loop if a signal interrupts waitpid()
1095 (fd.o #68945, Simon McVittie)
1097 • Clean up memory for parent nodes when objects are unexported
1098 (fd.o #60176, Thomas Fitzsimmons)
1100 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
1101 documented. Previously, it assumed its second parameter was TRUE.
1102 (fd.o #69165, Chengwei Yang)
1104 • Escape addresses containing non-ASCII characters correctly
1105 (fd.o #53499, Chengwei Yang)
1107 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
1109 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
1110 (fd.o #65923, Chengwei Yang)
1112 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
1113 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
1115 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
1116 that was never va_start()ed (fd.o #66300, Chengwei Yang)
1118 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
1120 • fix a regression test on platforms with strict alignment (fd.o #67279,
1123 • Avoid calling function parameters "interface" since certain Windows headers
1124 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
1126 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
1128 • Various thread-safety improvements to static variables (fd.o #68610,
1131 • Make "make -j check" work (fd.o #68852, Simon McVittie)
1133 • Fix a NULL pointer dereference on an unlikely error path
1134 (fd.o #69327, Sviatoslav Chagaev)
1136 • Improve valgrind memory pool tracking (fd.o #69326,
1139 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
1142 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
1143 (fd.o #66107, Chengwei Yang)
1146 · If accept4() fails with EINVAL, as it can on older Linux kernels
1147 with newer glibc, try accept() instead of going into a busy-loop.
1148 (fd.o #69026, Chengwei Yang)
1149 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
1150 for instance on Hurd or older Linux with a new glibc, try without
1151 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)
1152 · Fix a file descriptor leak on an error code path.
1153 (fd.o #69182, Sviatoslav Chagaev)
1154 · dbus-run-session: clear some unwanted environment variables
1155 (fd.o #39196, Simon)
1156 · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang)
1157 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
1158 · Use dbus-launch from the builddir for testing, not the installed copy
1159 (fd.o #37849, Chengwei Yang)
1160 · Fix compilation if writev() is unavailable (fd.o #69409,
1162 · Remove broken support for LOCAL_CREDS credentials passing, and
1163 document where each credential-passing scheme is used (fd.o #60340,
1165 · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality
1166 (fd.o #35881, #69787; Chengwei Yang)
1167 · dbus-monitor: be portable to NetBSD (fd.o #69842, Chengwei Yang)
1168 · dbus-launch: stop using non-portable asprintf (fd.o #37849, Simon)
1169 · Improve error reporting from the setuid activation helper (fd.o #66728,
1173 · Remove unavailable command-line options from 'dbus-daemon --help'
1174 (fd.o #42441, Ralf Habacker)
1175 · Add support for looking up local TCPv4 clients' credentials on
1176 Windows XP via the undocumented AllocateAndGetTcpExTableFromStack
1177 function (fd.o #66060, Ralf Habacker)
1178 · Fix insufficient dependency-tracking (fd.o #68505, Simon McVittie)
1179 · Don't include wspiapi.h, fixing a compiler warning (fd.o #68852,

1194 The “but is your thread-safety thread-safe?” release.
1198 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
1199 of service for system services. Vulnerability reported by Alexandru Cornea.
1204 • The Windows version of libdbus now contains a C++ source file, used
1205 to provide global initialization when the library is loaded.
1206 gcc (mingw*) users should ensure that g++ is also installed.
1208 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
1209 and was never the recommended option) has been removed. Expat is now a
1214 • It should now be safe to call dbus_threads_init_default() from any thread,
1215 at any time. Authors of loadable modules and plugins that use libdbus
1216 should consider doing so during initialization.
1217 (fd.o #54972, Simon McVittie)
1219 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
1223 · dbus-run-session: experimental new tool to start a temporary D-Bus
1224 session, e.g. for regression tests or a text console, replacing
1225 certain uses of dbus-launch which weren't really correct
1226 (fd.o #39196, Simon)
1230 • In dbus-daemon, don't crash if a .service file starts with key=value
1231 (fd.o #60853, Chengwei Yang)
1234 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
1235 on a platform not defining LOG_PERROR, such as Solaris or QNX.
1236 This regressed in 1.7.0. (Simon)
1237 · Fix an assertion failure if we try to activate systemd services before
1238 systemd connects to the bus (fd.o #50199, Chengwei Yang)
1239 · Avoid compiler warnings for ignoring the return from write()
1243 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
1244 so that Windows finds them (fd.o #59733, Ralf Habacker)
1246 D-Bus 1.7.2 (2013-04-25)
1249 The “only partially opaque” release.
1251 Configuration changes:
1253 • On non-QNX Unix platforms, the default limit on fds per message in the
1254 session bus configuration has reduced from 4096 to 1024. The default
1255 limit used on the system bus was already 1024. On QNX, both limits are
1256 reduced further, to 128.
1260 • D-Bus Specification 0.21
1261 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,

1298 The "Disingenuous Assertions" release.
1300 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
1301 remains the recommended version for long-term-supported distributions
1302 or the upcoming GNOME 3.8 release.
1304 Build-time configuration changes:
1306 • The --with-dbus-session-bus-default-address configure option is no longer
1307 supported. Use the new --with-dbus-session-bus-connect-address and
1308 --with-dbus-session-bus-listen-address options instead. On Windows, you
1309 usually want them to have the same argument; on Unix, the defaults are
1312 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
1313 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
1314 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
1316 • cmake/cross-compile.sh has been removed. Instead, please use a
1317 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
1318 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
1319 as documented in "info automake Cross-Compilation", and set
1320 PKG_CONFIG_PATH appropriately.
1324 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
1325 • man2html is no longer used.
1329 • D-Bus Specification 0.20
1330 · actually say that /org/freedesktop/DBus is the object that
1331 implements o.fd.DBus (fd.o #51865, Colin Walters)
1332 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
1333 · stop claiming that all basic types work just like INT32 (strings don't!)
1335 • The "source code" for the man pages is now Docbook XML, eliminating
1336 the outdated duplicate copies used when building with CMake.
1337 (fd.o #59805; Ralf Habacker, Simon McVittie)
1341 • In the activation helper, when compiled for tests, do not reset the system
1342 bus address, fixing the regression tests. (fd.o #52202, Simon)
1344 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
1345 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
1347 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

1366 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
1369 · The default session bus listening and connecting address is now
1370 "autolaunch:", which makes D-Bus on Windows interoperate with itself
1371 and GDBus "out of the box". Use the configure options and cmake variables
1372 described above if you require a different autolaunch scope.
1373 (fd.o #38201, Simon McVittie)
1374 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
1376 • Create session.d, system.d directories under CMake (fd.o #41319,
1379 D-Bus 1.6.8 (2012-09-28)
1382 The "Fix one thing, break another" release.
1384 • Follow up to CVE-2012-3524: The additional hardening
1385 work to use __secure_getenv() as a followup to bug #52202
1386 broke certain configurations of gnome-keyring. Given
1387 the difficulty of making this work without extensive
1388 changes to gnome-keyring, use of __secure_getenv() is

1430 (fd.o #51032, Simon McVittie)
1432 • Disconnect "developer mode" (assertions, verbose mode etc.) from
1433 Automake maintainer mode. D-Bus developers should now configure with
1434 --enable-developer. Automake maintainer mode is now on by default;
1435 distributions can disable it with --disable-maintainer-mode.
1436 (fd.o #34671, Simon McVittie)
1438 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
1439 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
1442 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
1444 D-Bus 1.6.0 (2012-06-05)
1447 The “soul of this machine has improved” release.
1449 This version starts a new stable branch of D-Bus: only bug fixes will
1450 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
1452 Summary of changes since 1.4.x:

1491 Changes since 1.5.12:
1493 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
1494 spec-compliance (fd.o #48580, David Zeuthen)
1496 • Don't use install(1) within the source/build trees, fixing the build as
1497 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
1499 • Add missing commas in some tcp and nonce-tcp addresses, and remove
1500 an unused duplicate copy of the nonce-tcp transport in Windows builds
1501 (fd.o #45896, Simon McVittie)
1503 D-Bus 1.5.12 (2012-03-27)
1506 The “Big Book of Science” release.
1508 • Add public API to validate various string types:
1509 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
1510 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
1511 (fd.o #39549, Simon McVittie)
1513 • Turn DBusBasicValue into public API so bindings don't need to invent their
1514 own "union of everything" type (fd.o #11191, Simon McVittie)
1516 • Enumerate data files included in the build rather than using find(1)
1517 (fd.o #33840, Simon McVittie)

1526 (fd.o #47321, Andoni Morales Alastruey)
1528 D-Bus 1.5.10 (2012-02-21)
1531 The "fire in Delerium" release.
1533 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
1534 and SUSv2) is now required.
1536 • D-Bus Specification 0.19:
1537 · Formally define unique connection names and well-known bus names,
1538 and document best practices for interface, bus, member and error names,
1539 and object paths (fd.o #37095, Simon McVittie)
1540 · Document the search path for session and system services on Unix, and
1541 where they should be installed by build systems (fd.o #21620, fd.o #35306;
1543 · Document the systemd transport (fd.o #35232, Lennart Poettering)
1545 • Make dbus_threads_init() use the same built-in threading implementation
1546 as dbus_threads_init_default(); the user-specified primitives that it
1547 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
1549 • Allow all configured auth mechanisms, not just one (fd.o #45106,
1552 • Improve cmake build system (Ralf Habacker):
1553 · simplify XML parser dependencies (fd.o #41027)
1554 · generate build timestamp (fd.o #41029)
1555 · only create batch files on Windows
1556 · fix option and cache syntax
1557 · add help-options target
1558 · share dbus-arch-deps.h.in with autotools rather than having our
1559 own version (fd.o #41033)
1561 • Build tests successfully with older GLib, as found in e.g. Debian 6
1562 (fd.o #41219, Simon McVittie)
1564 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
1566 • Build documentation correctly if man2html doesn't support filenames on
1567 its command-line (fd.o #43875, Jack Nagel)
1569 • Improve test coverage. To get even more coverage, run the tests with
1570 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
1572 • Reduce the size of the shared library by moving functionality only used
1573 by dbus-daemon, tests etc. into their internal library and deleting
1574 unused code (fd.o #34976, #39759; Simon McVittie)
1576 • Add dbus-daemon --nopidfile option, overriding the configuration, for
1577 setups where the default configuration must include <pidfile/> to avoid
1578 breaking traditional init, but the pid file is in fact unnecessary; use
1579 it under systemd to improve startup time a bit (fd.o #45520,
1582 • Optionally (if configured --with-valgrind) add instrumentation to debug
1583 libdbus and associated tools more meaningfully under Valgrind
1584 (fd.o #37286, Simon McVittie)
1586 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
1588 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
1590 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
1591 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
1592 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
1595 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
1599 · Replace our broken reimplementation of recursive mutexes, which has
1600 been broken since 2006, with an ordinary pthreads recursive mutex
1601 (fd.o #43744; Sigmund Augdal, Simon McVittie)
1602 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
1603 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
1604 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
1605 · When running under systemd, use it instead of ConsoleKit to check
1606 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
1607 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
1608 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
1609 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
1610 (fd.o #41218, Simon McVittie)
1611 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
1612 helper doesn't obey environment variables to avoid privilege escalation
1613 attacks, so make the system bus follow the same rules
1614 (fd.o #21620, Simon McVittie)
1617 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
1618 Jesper Dam, Ralf Habacker)
1619 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
1622 D-Bus 1.5.8 (2011-09-21)
1625 The "cross-metering" release.
1627 In addition to dead code removal and refactoring, this release contains all
1628 of the bugfixes from 1.4.16.
1630 • Clean up dead code, and make more warnings fatal in development builds
1631 (fd.o #39231, fd.o #41012; Simon McVittie)
1633 • If full test coverage is requested via --enable-tests, strictly require
1634 Python, pygobject and dbus-python, which are required by some tests; if not,
1635 and Python is missing, skip those tests rather than failing
1636 (fd.o #37847, Simon McVittie)
1638 • When using cmake, provide the same version-info API in the installed headers
1639 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
1641 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
1643 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
1645 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
1648 • Fix duplicates in authors list (Ralf Habacker)
1650 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
1651 (fd.o #39879, Chris Mayo)
1653 • Fix a small memory leak, and a failure to report errors, when updating
1654 a service file entry for activation (fd.o #39230, Simon McVittie)
1657 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
1658 Brian Cameron, Simon McVittie)
1659 · On systems that use libcap-ng but not systemd, drop supplemental groups
1660 when switching to the daemon user (Red Hat #726953, Steve Grubb)
1661 · Make the cmake build work again on GNU platforms (fd.o #29228,
1663 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
1664 like Solaris (fd.o #40313, Dagobert Michelsen)
1665 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
1666 (fd.o #40235, Simon McVittie)
1667 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
1668 (fd.o #39987, Simon McVittie)
1669 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
1670 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
1673 · Fix compilation on MSVC, which doesn't understand "inline" with its
1674 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
1675 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
1676 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
1678 D-Bus 1.5.6 (2011-07-29)
1681 The "weird, gravy-like aftertaste" release.
1683 In addition to new features and refactoring, this release contains all of the
1684 bugfixes from 1.4.14.
1686 Potentially incompatible (Bustle and similar debugging tools will need
1687 changes to work as intended):
1689 • Do not allow match rules to "eavesdrop" (receive messages intended for a
1690 different recipient) by mistake: eavesdroppers must now opt-in to this
1691 behaviour by putting "eavesdrop='true'" in the match rule, which will
1692 not have any practical effect on buses where eavesdropping is not allowed
1693 (fd.o #37890, Cosimo Alfarano)
1697 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
1698 Cosimo Alfarano, Simon McVittie)
1699 · add the "eavesdrop" keyword to match rules
1700 · define eavesdropping, unicast messages and broadcast messages
1701 · stop claiming that match rules are needed to match unicast messages to you
1702 · promote the type system to be a top-level section
1704 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
1705 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
1706 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
1708 • Consistently use atomic operations on everything that is ever manipulated
1709 via atomic ops, as was done for changes to DBusConnection's refcount in
1710 1.4.12 (fd.o #38005, Simon McVittie)
1712 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
1715 • Make "make check" in a clean tree work, by not running tests until
1716 test data has been set up (fd.o #34405, Simon McVittie)
1718 • The dbus-daemon no longer busy-loops if it has a very large number of file
1719 descriptors (fd.o #23194, Simon McVittie)
1721 • Refactor message flow through dispatching to avoid locking violations if
1722 the bus daemon's message limit is hit; remove the per-connection link cache,
1723 which was meant to improve performance, but now reduces it (fd.o #34393,
1726 • Some cmake fixes (Ralf Habacker)
1728 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
1729 Simon McVittie, Lennart Poettering)
1731 • Stop storing two extra byte order indicators in each D-Bus message
1732 (fd.o #38287, Simon McVittie)
1734 • Add an optional Stats interface which can be used to get statistics from
1735 a running dbus-daemon if enabled at configure time with --enable-stats
1736 (fd.o #34040, Simon McVittie)
1738 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
1740 • Documentation (fd.o #36156, Simon McVittie):
1741 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
1742 · install more documentation automatically, including man2html output
1743 · put dbus.devhelp in the right place (it must go in ${htmldir})
1746 · look for system services in /lib/dbus-1/system-services in addition to all
1747 the other well-known locations; note that this should always be /lib,
1748 even on platforms where shared libraries on the root FS would go in /lib64,
1749 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
1750 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
1752 • Windows-specific (Ralf Habacker):
1753 · fix use of a mutex for autolaunch server detection
1754 · don't crash on malloc failure in _dbus_printf_string_upper_bound
1756 D-Bus 1.5.4 (2011-06-10)
1759 Security (local denial of service):
1761 • Byte-swap foreign-endian messages correctly, preventing a long-standing
1762 local DoS if foreign-endian messages are relayed through the dbus-daemon
1763 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
1764 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
1768 • The constant to use for an infinite timeout now has a name,
1769 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
1770 which can be used for source compatibility with older versions of libdbus.
1772 • If GLib and DBus-GLib are already installed, more tests will be built,
1773 providing better coverage. The new tests can also be installed via
1774 ./configure --enable-installed-tests
1775 for system integration testing, if required. (fd.o #34570, Simon McVittie)
1779 • Consistently use atomic operations for the DBusConnection's refcount,
1780 fixing potential threading problems (fd.o #38005, Simon McVittie)
1782 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
1783 small (300KiB on x86-64) and it frequently doesn't work in unusual
1784 toolchains. To optimize for minimum installed size, you should benchmark
1785 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
1786 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
1788 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
1789 (fd.o #35880, Timothy Redaelli)
1791 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
1792 when not using a DESTDIR (fd.o #37870, Simon McVittie)
1794 • Windows-specific changes:
1795 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
1797 D-Bus 1.5.2 (2011-06-01)
1800 The "Boar Hunter" release.
1802 Notes for distributors:
1804 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
1805 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
1806 toolchain supports it reliably, via something like:
1808 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
1810 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
1814 • D-Bus Specification v0.17

1819 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
1820 • Allow --disable-gc-sections, in case your toolchain offers the
1821 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
1822 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
1823 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
1824 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
1825 • Ensure that maintainers upload documentation with the right permissions

1834 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
1835 (fd.o #35228, Lennart Poettering)
1836 • In the regression tests, don't report fds as "leaked" if they were open
1837 on startup (fd.o #35173, Simon McVittie)
1838 • Make dbus-monitor bail out if asked to monitor more than one bus,
1839 rather than silently using the last one (fd.o #26548, Will Thompson)
1840 • Clarify documentation (fd.o #35182, Simon McVittie)
1841 • Clean up minor dead code and some incorrect error handling

1856 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
1857 · Make argNpath support object paths, not just object-path-like strings,
1858 and document it better (fd.o #31818, Will Thompson)
1859 • Let the bus daemon implement more than one interface (fd.o #33757,
1861 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
1863 • Require user intervention to compile with missing 64-bit support
1864 (fd.o #35114, Simon McVittie)
1865 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
1866 • Raise UnknownObject instead of UnknownMethod for calls to methods on
1867 paths that are not part of the object tree, and UnknownInterface for calls
1868 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
1870 D-Bus 1.4.8 (2011-04-08)
1873 The "It's like the beginning of a lobster" release.
1875 • Rename configure.in to configure.ac, and update it to modern conventions
1876 (fd.o #32245; Javier Jardón, Simon McVittie)
1877 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
1879 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
1880 --disable-x11-autolaunch configure option to prevent it altogether
1881 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
1882 • Install the documentation, and an index for Devhelp (fd.o #13495,
1883 Debian #454142; Simon McVittie, Matthias Clasen)
1884 • If checks are not disabled, check validity of string-like types and
1885 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
1886 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
1887 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
1888 • Break up a huge conditional in config-parser so gcov can produce coverage
1889 data (fd.o #10887, Simon McVittie)
1890 • List which parts of the Desktop Entry specification are applicable to
1891 .service files (fd.o #19159, Sven Herzberg)
1892 • Don't suppress service activation if two services have the same Exec=

1903 The "1, 2, miss a few, 99, 100" release.
1905 • Remove unfinished changes intended to support GTest-based tests,
1906 which were mistakenly included in 1.4.4
1908 D-Bus 1.4.4 (2010-02-17)
1911 • Switch back to using even micro versions for stable releases; 1.4.1
1912 should have been called 1.4.2, so skip that version number
1913 • Don't leave bad file descriptors being watched when spawning processes,
1914 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
1915 also LP#656134, LP#680444, LP#713157)
1916 • Check for MSG_NOSIGNAL correctly
