1 dbus 1.12.20 (UNRELEASED)
2 =========================
6 dbus 1.12.18 (2020-06-02)
7 =========================
9 The “telepathic vines” release.
11 Denial of service fixes:
13 • CVE-2020-12049: If a message contains more file descriptors than can
14 be sent, close those that did get through before reporting error.
15 Previously, a local attacker could cause the system dbus-daemon (or
16 another system service with its own DBusServer) to run out of file
17 descriptors, by repeatedly connecting to the server and sending fds that

20 (dbus#294, GHSL-2020-057; Simon McVittie)
24 • Fix a crash when the dbus-daemon is terminated while one or more
25 monitors are active (dbus#291, dbus!140; Simon McVittie)
27 • The dbus-send(1) man page now documents --bus and --peer instead of
28 the old --address synonym for --peer, which has been deprecated since
29 the introduction of --bus and --peer in 1.7.6
30 (fd.o #48816, dbus!115; Chris Morin)
32 • Fix a wrong environment variable name in dbus-daemon(1)
33 (dbus#275, dbus!122; Mubin, Philip Withnall)
35 • Fix formatting of dbus_message_append_args example
36 (dbus!126, Felipe Franciosi)
38 • Avoid a test failure on Linux when built in a container as uid 0, but
39 without the necessary privileges to increase resource limits
40 (dbus!58, Debian #908092; Simon McVittie)
42 • When building with CMake, cope with libX11 in a non-standard location
43 (dbus!129, Tuomo Rinne)
45 dbus 1.12.16 (2019-06-11)
46 =========================
48 The “tree cat” release.
52 • CVE-2019-12749: Do not attempt to carry out DBUS_COOKIE_SHA1
53 authentication for identities that differ from the user running the
54 DBusServer. Previously, a local attacker could manipulate symbolic
55 links in their own home directory to bypass authentication and connect
56 to a DBusServer with elevated privileges. The standard system and
57 session dbus-daemons in their default configuration were immune to this
58 attack because they did not allow DBUS_COOKIE_SHA1, but third-party
59 users of DBusServer such as Upstart could be vulnerable.
60 Thanks to Joe Vennix of Apple Information Security.
61 (dbus#269, Simon McVittie)
63 dbus 1.12.14 (2019-05-17)
64 =========================
66 The “reclaimed floorboards” release.
70 • Raise soft fd limit to match hard limit, even if unprivileged.
71 This makes session buses with many clients, or with clients that make
72 heavy use of fd-passing, less likely to suffer from fd exhaustion.
73 (dbus!103, Simon McVittie)
77 • If a privileged dbus-daemon has a hard fd limit greater than 64K, don't
78 reduce it to 64K, ensuring that we can put back the original fd limits
79 when carrying out traditional (non-systemd) activation. This fixes a
80 regression with systemd >= 240 in which system services inherited
81 dbus-daemon's hard and soft limit of 64K fds, instead of the intended
82 soft limit of 1K and hard limit of 512K or 1M.
83 (dbus!103, Debian#928877; Simon McVittie)
85 • Fix build failures caused by an AX_CODE_COVERAGE API change in newer
86 autoconf-archive versions (dbus#249, dbus!88; Simon McVittie)
88 • Fix build failures with newer autoconf-archive versions that include
89 AX_-prefixed shell variable names (dbus#249, dbus!86; Simon McVittie)
91 • Parse section/group names in .service files according to the syntax
92 from the Desktop Entry Specification, rejecting control characters
93 and non-ASCII in section/group names (dbus#208, David King)
95 • Fix various -Wlogical-op issues that cause build failure with newer
96 gcc versions (dbus#225, dbus!109; David King)
98 • Don't assume we can set permissions on a directory, for the benefit of
99 MSYS and Cygwin builds (dbus#216, dbus!110; Simon McVittie)
101 • Don't overwrite PKG_CONFIG_PATH and related environment variables when
102 the pkg-config-based version of DBus1Config is used in a CMake project
103 (dbus#267, dbus!96; Clemens Lang)
105 dbus 1.12.12 (2018-12-04)
106 =========================
108 The “draconic disciple” release.
110 dbus version control is now hosted on freedesktop.org's Gitlab
111 installation, and bug reports and feature requests have switched from
112 Bugzilla bugs (indicated by "fd.o #nnn") to Gitlab issues ("dbus#nnn")
113 and merge requests ("dbus!nnn").
117 • Reference the freedesktop.org Code of Conduct (Simon McVittie)
121 • Stop the dbus-daemon leaking memory (an error message) if delivering
122 the message that triggered auto-activation is forbidden. This is
123 technically a denial of service because the dbus-daemon will
124 run out of memory eventually, but it's a very slow and noisy one,
125 because all the rejected messages are also very likely to have
126 been logged to the system log, and its scope is typically limited by
127 the finite number of activatable services available.
128 (dbus#234, Simon McVittie)
130 • Remove __attribute__((__malloc__)) attribute on dbus_realloc(),
131 which does not meet the criteria for that attribute in gcc 4.7+,
132 potentially leading to miscompilation (fd.o #107741, Simon McVittie)
134 • Fix some small O(1) memory leaks (fd.o #107320, Simon McVittie)
136 • Fix printf formats for pointer-sized integers on 64-bit Windows
137 (fd.o #105662, Ralf Habacker)
139 • Always use select()-based poll() emulation on Darwin-based OSs
140 (macOS, etc.) and on Interix, similar to what libcurl does
141 (dbus#232, dbus!19; Simon McVittie)
143 • Extend a test timeout to avoid spurious failures in CI
144 (dbus!26, Simon McVittie)
148 • Add Travis-CI builds for 64-bit Windows using mingw-w64
149 (fd.o #105662, Ralf Habacker)
151 • Add Gitlab-CI integration (fd.o #108177, Simon McVittie)
153 dbus 1.12.10 (2018-08-02)
154 =========================
156 The “beam deflection” release.
160 • Prevent reading up to 3 bytes beyond the end of a truncated message.
161 This could in principle be an information leak or denial of service
162 on the system bus, but is not believed to be exploitable to crash
163 the system bus or leak interesting information in practice.
164 (fd.o #107332, Simon McVittie)
166 • Fix build with gcc 8 -Werror=cast-function-type
167 (fd.o #107349, Simon McVittie)
169 • Fix warning from gcc 8 about suspicious use of strncpy() when
170 populating struct sockaddr_un (fd.o #107350, Simon McVittie)
172 • Fix a minor memory leak when a DBusServer listens on a new address
173 (fd.o #107194, Simon McVittie)
175 • Fix an invalid NULL argument to rmdir() if a nonce-tcp DBusServer
176 runs out of memory (fd.o #107194, Simon McVittie)
178 • Don't use misleading errno-derived error names if getaddrinfo() or
179 getnameinfo() fails with a code other than EAI_SYSTEM
180 (fd.o #106395, Simon McVittie)
182 • Skip tests that require working TCP if we are in a container environment
183 where 127.0.0.1 cannot be resolved (fd.o #106812, Simon McVittie)
185 dbus 1.12.8 (2018-04-30)
186 ========================
188 The “golden super-velociraptor” release.
192 • The Devhelp documentation index is now in version 2 format
193 (fd.o #106186, Simon McVittie)
195 • Give the dbus-daemon man page some scarier warnings about
196 <allow_anonymous/> and non-local TCP, which are insecure and should
197 not be used, particularly for the standard system and session buses
198 (fd.o #106004, Simon McVittie)
202 • Fix installation of Ducktype documentation with newer yelp-build
203 versions (fd.o #106171, Simon McVittie)
205 dbus 1.12.6 (2018-03-01)
206 ========================
208 The “just the one swan, actually” release.
212 • Increase system dbus-daemon's RLIMIT_NOFILE rlimit before it drops
213 privileges, because it won't have permission afterwards. This fixes a
214 regression in dbus 1.10.18 and 1.11.0 which made the standard system bus
215 more susceptible to deliberate or accidental denial of service.
216 (fd.o #105165, David King)
218 dbus 1.12.4 (2018-02-08)
219 ========================
221 The “Stria Campania 115” release.
225 • When iterating the DBusConnection while blocking on a pending call,
226 don't wait for I/O if that pending call already has a result; and make
227 sure that whether it has a result is propagated in a thread-safe way.
228 This prevents certain multi-threaded calling patterns from blocking
229 until their timeout even when they should have succeeded sooner.
230 (fd.o #102839; Manish Narang, Michael Searle)
232 • Report the correct error if OOM is reached while trying to listen
233 on a TCP socket (fd.o #89104, Simon McVittie)
235 • Fix assertion failures in recovery from OOM while setting up a
236 DBusServer (fd.o #89104, Simon McVittie)
238 • Add a missing space to a warning message (fd.o #103729, Thomas Zajic)
240 • Expand ${bindir} correctly when pkg-config is asked for dbus_daemondir
241 (fd.o #104265, Benedikt Heine)
243 • On Linux systems with systemd < 237, if ${localstatedir}/dbus doesn't
244 exist, create it before trying to create ${localstatedir}/dbus/machine-id
245 (fd.o #104577, Chris Lesiak)
247 • Fix escaping in dbus-api-design document (fd.o #104925, Philip Withnall)
249 dbus 1.12.2 (2017-11-13)
250 ========================
252 The “spider pumpkin” release.
256 • Log a warning if a new connection cannot be accepted due to an
257 out-of-memory condition or failure to identify its AppArmor or
258 SELinux context (fd.o #103592, Simon McVittie)
262 • Make use of $(MKDIR_P) compatible with install-sh, fixing build when a
263 GNU-compatible `mkdir -p` is not available (fd.o #103521, ilovezfs)
265 • When building for Windows with Autotools, avoid `echo -e`, fixing
266 cross-compilation on non-GNU platforms like macOS
267 (fd.o #103493, Tony Theodore)
269 • Fix crashes in the server side of the nonce-tcp: transport under
270 various error conditions. This transport should normally only be used
271 on Windows, where AF_UNIX sockets are unavailable; the unix: transport
272 is the only one recommended for production use on Unix platforms.
273 (fd.o #103597, Simon McVittie)
277 • Improve test coverage on Travis-CI (Simon McVittie)
279 dbus 1.12.0 (2017-10-30)
280 ========================
282 The “gingerbread skull” release.
284 1.12.x is a new stable branch, recommended for use in OS
287 Summary of major changes between 1.10.x and 1.12.0
288 --------------------------------------------------
292 • Expat >= 2.1.0 is required.
293 • GLib >= 2.40 is required if full test coverage is enabled.
294 • [Linux] libselinux >= 2.0.86 is required if SELinux support is
296 • [Unix] dbus now requires an <inttypes.h> that defines C99 constants
297 such as PRId64 and PRIu64, except when building for Windows.
298 • [Autotools] Building from git (but not from tarballs) with Autotools
299 now requires macros from the GNU Autoconf Archive.
300 • [CMake] Builds done using CMake now require CMake 3.0.2.
302 Build-time configuration changes:
304 • Expat is now found using pkg-config. See the release notes for
306 • The --disable-compiler-optimisations and --enable-compiler-coverage
307 options no longer exist. See the release notes for 1.11.4 and 1.11.8.
308 • [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
309 options no longer exist. See the release notes for 1.11.20.
310 • [Unix] Flag files in /var/run/console/${username} are no longer
311 checked for at_console by default. See the release notes for 1.11.18.
312 • [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
313 and packagers will now need to add these downstream (most already do).
314 See the release notes for 1.11.18.
315 • [Unix] The process ID file no longer has a different default location
316 on Red Hat derivatives. See the release notes for 1.11.18.
317 • [Unix] ${runstatedir} is now independent of ${localstatedir} with
318 recent Autotools versions. See the release notes for 1.11.16.
319 • [Windows] The WINDRES variable is no longer used. See the release
324 • Eavesdropping is officially deprecated in favour of BecomeMonitor.
325 See the release notes for spec version 0.31 (in dbus 1.11.14).
326 • [Unix] Flag files in /var/run/console/${username} are deprecated.
327 See the release notes for 1.11.18.
331 • <allow> and <deny> rules in dbus-daemon configuration can now
332 include send_broadcast="true", send_broadcast="false",
333 max_unix_fds="N", min_unix_fds="N" (for some integer N).
334 See the release notes for 1.11.18.
335 • dbus_try_get_local_machine_id() is like
336 dbus_get_local_machine_id(), but returns a DBusError.
337 • New APIs around DBusMessageIter to simplify cleanup.
338 See the release notes for 1.11.16.
339 • The message bus daemon now implements the standard Introspectable,
340 Peer and Properties interfaces. See the release notes for
341 dbus 1.11.14 and spec version 0.31.
342 • DTDs for introspection XML and bus configuration are installed.
343 • dbus can be compiled to be relocatable, making it more suitable for
344 binary bundling with other software. On Windows, this is on by
346 • [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
347 never uses Linux abstract sockets, which is advantageous for
348 containers. On non-Linux it is equivalent to unix:tmpdir=….
349 See the release notes for dbus 1.11.14 and spec version 0.31.
350 • [Unix] New option "dbus-launch --exit-with-x11".
351 • [Unix] Session managers can create transient .service files in
352 $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
353 • [Unix] A sysusers.d snippet can create the messagebus user on-demand.
355 Miscellaneous behaviour changes:
357 • [Unix] The session bus now logs to syslog if it was started by
359 • [Unix] Internal warnings are logged to syslog if configured.
360 • [Unix] Exceeding an anti-DoS limit is logged to syslog if configured,
363 Changes since 1.11.22 release candidate
364 ---------------------------------------
366 Standard stable-branch changes:
368 • Disable warnings about use of deprecated functions (Simon McVittie)
372 • Don't distribute files generated by ./configure in the source tarball
373 (fd.o #103420, Simon McVittie)
377 • Remove some unused files from the git repository
378 (fd.o #103420, Simon McVittie)
380 D-Bus 1.11.22 (2017-10-23)
381 ==========================
383 The “fire surface” release.
385 This is the first release-candidate for the 1.12.0 stable release.
387 Build-time configuration changes:
389 • When building for Windows with Autotools, setting the WINDRES variable
390 no longer works to select a non-standard resource compiler. Use
391 libtool's standard RC variable instead, for example
392 "./configure RC=i686-w64-mingw32-windres"
396 • Builds done using CMake now require CMake 3.0.2.
400 • When building for Windows, improve quality of metadata in
401 libdbus-1-3.dll (fd.o #103015, Ralf Habacker)
405 • Fix a typo "uint 16" in dbus-send(1) man page
406 (fd.o #103075, David King)
408 • When building for Windows, libdbus-1-3.dll always includes version
409 information. Previously, this was missing if using CMake and any
410 non-MSVC compiler. (fd.o #103015, Ralf Habacker)
412 • Fix the build with MSVC, which regressed with the #102558 fix in
413 1.11.20. (fd.o #102558, Ralf Habacker)
417 • Simplify Windows resource embedding
418 (fd.o #103015, Simon McVittie)
420 D-Bus 1.11.20 (2017-10-03)
423 The “wraith stun” release.
425 Build-time configuration changes:
427 • The --enable-abstract-sockets and --disable-abstract-sockets options
428 no longer exist. Support for Linux's abstract AF_UNIX sockets is now
429 unconditionally enabled on Linux and disabled everywhere else.
430 (fd.o #34905, Simon McVittie)
434 • Make slower tests less likely to time out, and improve diagnostics if
435 tests do time out (fd.o #103009, Simon McVittie)
437 • On Windows, don't compile an unused stub implementation of
438 _dbus_set_signal_handler() (fd.o #103010, Simon McVittie)
442 • Be more careful to save and restore errno in POSIX async signal
443 handlers (fd.o #103010, Simon McVittie)
445 • On Windows, embed a manifest in dbus-update-activation-environment.exe
446 so that the heuristics used for UAC do not assume it needs elevated
447 privileges due to its name containing "update"
448 (fd.o #102558, Ralf Habacker)
450 • On Windows with Automake, embed version information in libdbus-1,
451 as was meant to happen in all versions since 2009
452 (fd.o #103015, Simon McVittie)
454 D-Bus 1.11.18 (2017-09-25)
457 The “vampire conquistador” release.
459 Build-time configuration changes:
461 • By default, dbus-daemon on Unix no longer checks for flag files
462 /var/run/console/${username} created by the obsolete pam_console and
463 pam_foreground PAM modules when deciding whether ${username} is
464 currently at the console. The old default behaviour can be restored
465 by specifying --with-console-auth-dir=/var/run/console in the
466 recommended Autotools build system, or
467 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
468 now deprecated, and will be removed in dbus 1.13 unless feedback via
469 fd.o #101629 indicates that this would be problematic.
470 (fd.o #101629, Simon McVittie)
472 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
473 script for Cygwin, are no longer provided in the upstream dbus
474 source. We recommend that distributors who support non-systemd service
475 management should maintain their own init scripts or other service
476 manager integration as part of their downstream packaging, similar to
477 the way Debian distributes a Debian-specific LSB init script for dbus.
479 The systemd unit continues to be maintained as part of the upstream
480 dbus source, because it receives regular testing and maintenance.
482 (fd.o #101706, Simon McVittie)
484 • The process ID file created by the system bus is no longer influenced
485 by the --with-init-scripts=redhat configure option or the presence of
486 /etc/redhat-release at build time. If your OS's init script or other
487 service management relies on the Red Hat-style pid file, it can be
488 restored by specifying --with-system-pid-file=/run/messagebus.pid at
489 configure time or using the <pidfile> directive in bus configuration.
491 Note that the upstream-supplied systemd unit runs dbus-daemon with
492 the --nopidfile option, so it does not normally write a pid file,
493 regardless of whether the OS is Red-Hat-derived or not.
495 (fd.o #101706, Simon McVittie)
499 • <allow> and <deny> rules in dbus-daemon configuration can now
500 include send_broadcast="true" or send_broadcast="false", which make
501 the rule only match broadcast signals, or only match messages that
502 are not broadcast signals, respectively.
503 (fd.o #29853, Simon McVittie)
505 • <allow> and <deny> rules can now be configured to apply only to
506 messages with or without Unix file descriptors attached. This would
507 typically be used in rules like these:
508 <allow send_destination="..." max_unix_fds="0"/>
509 <deny send_destination="..." min_unix_fds="1"/>
510 <deny receive_sender="..." min_unix_fds="1"/>
511 but can also be used to set a nonzero upper limit on the number of
513 <allow send_destination="..." max_unix_fds="4"/>
514 (fd.o #101848, Simon McVittie)
516 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
517 now respects the HOME environment variable on the client side, and
518 on the server side when the uid attempting to connect is the same
519 as the uid of the server. This allows the automated tests to pass in
520 environments where the user's "official" home directory in /etc/passwd
521 is nonexistent, such as Debian autobuilders.
522 (fd.o #101960, Simon McVittie)
526 • When parsing dbus-daemon configuration, tell Expat not to use
527 cryptographic-quality entropy as a salt for its hash tables: we trust
528 the configuration files, so we are not concerned about algorithmic
529 complexity attacks via hash table collisions. This prevents
530 dbus-daemon --system from holding up the boot process (and causing
531 early-boot system services like systemd, logind, networkd to time
532 out) on entropy-starved embedded systems.
533 (fd.o #101858, Simon McVittie)
535 • Avoid a -Werror=declaration-after-statement build failure on Solaris
536 (fd.o #102145, Alan Coopersmith)
538 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
539 to LOG_INFO, matching how we use this log level in practice
540 (fd.o #102686, Simon McVittie)
542 D-Bus 1.11.16 (2017-07-27)
545 The “south facing garden” release.
547 Build-time configuration changes:
549 • The Autotools build system now supports varying ${runstatedir}
550 independently of ${localstatedir}, if using an Autoconf version
551 that has that feature; version 2.70 will eventually have this, but
552 many Linux distributions add it to version 2.69 as a patch.
553 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
554 and runstatedir=/run. (fd.o #101569, Simon McVittie)
558 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
559 and dbus_message_iter_abandon_container_if_open() simplify the
560 single-exit-point ("goto out") style of resource cleanup. The API
561 documentation around DBusMessageIter and containers has also been
562 clarified. (fd.o #101568, Simon McVittie)
566 • Fix the implementation of re-enabling a timeout (again) so that its
567 countdown is always restarted as intended. (fd.o #95619,
570 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
571 available to all users on the system bus (fd.o #101700, Simon McVittie)
573 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
574 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
576 • dbus_message_iter_open_container() no longer leaks memory if it runs out
577 of memory. (fd.o #101568, Simon McVittie)
579 • dbus_message_append_args_valist() no longer leaks memory if given an
580 unsupported type. This situation is still considered to be a programming
581 error which needs to be corrected by the user of libdbus.
582 (fd.o #101568, Simon McVittie)
584 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
585 will no longer report that their arguments were invalid if they run out
586 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
588 • Ensure that tests fail if they would otherwise have tried to connect to
589 the real session bus (fd.o #101698, Simon McVittie)
591 • Make build-time tests cope with finding Python 3, but not Python 2
592 (fd.o #101716, Simon McVittie)
594 Internal changes relevant to dbus developers:
596 • DBusVariant is a new mechanism to copy single values from a message into
597 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
599 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
600 Logging an ERROR message does not make the process exit; the caller
601 is responsible for calling abort() or exit(), whichever is more appropriate.
602 (fd.o #101568, Simon McVittie)
604 • Better test coverage (fd.o #101568, Simon McVittie)
606 D-Bus 1.11.14 (2017-06-29)
609 The “irrational fear of bees” release.
613 • Expat >= 2.1.0 is always required
614 • libselinux >= 2.0.86 is required if SELinux support is enabled
615 • GLib >= 2.40 is required if full test coverage is enabled
617 Build-time configuration changes:
619 • We now use pkg-config to find libexpat in Autotools builds. This requires
620 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
621 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
622 itself cause compilation failures.
624 As with all pkg-config-based configure checks, you can use
625 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
626 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
627 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
630 (fd.o #69801, Simon McVittie)
632 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
633 is required due to the removal of explicit refcounting for SIDs.
634 (fd.o #100912, Laurent Bigonville)
638 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
639 as a side-effect of a sufficiently privileged process merely reading the
640 machine ID. It is no longer copied as a side-effect of reading.
641 Running dbus-uuidgen --ensure, which should be done after installing dbus,
642 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
643 former exists and the latter does not.
644 (fd.o #101257, Simon McVittie)
646 • The undocumented Verbose interface, and the GetAllMatchRules method on
647 the undocumented Stats interface, must now be used via the object path
648 /org/freedesktop/DBus. Previously, they existed on all object paths.
649 (fd.o #101257, Simon McVittie)
651 • AddMatch() with a match rule containing eavesdrop='true' will now fail
652 unless called by either the same user as the dbus-daemon, or Unix uid 0
653 (root), matching the restrictions applied to the newer BecomeMonitor()
654 method. On the session bus this has no practical effect. On the system
655 bus this will prevent certain configurations that already did not
656 work well in practice. (fd.o #101567, Simon McVittie)
660 • D-Bus Specification version 0.31
661 · Don't require implementation-specific search paths to be lowest
663 · Correct regex syntax for optionally-escaped bytes in addresses so it
664 includes hyphen-minus, forward slash and underscore as intended
665 · Describe all message bus methods in the same section
666 · Clarify the correct object path for method calls to the message bus
667 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
668 · Document that the message bus implements Introspectable, Peer and
670 · Add new Features and Interfaces properties for message bus
672 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
674 · Don't require eavesdrop='true' to be accepted from connections not
675 sufficiently privileged to use it successfully
676 · Formally deprecate eavesdropping in favour of BecomeMonitor
677 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
678 Simon McVittie, Tom Gundersen)
680 • Implement the Properties and Peer interfaces in dbus-daemon
681 (fd.o #101257, Simon McVittie)
683 • New function dbus_try_get_local_machine_id() is like
684 dbus_get_local_machine_id(), but returning a DBusError. Other code
685 that needs the machine ID will now report a recoverable error (instead
686 of logging to stderr and aborting) if no machine ID is available.
687 Generating a machine ID is still considered to be a required part of
688 installing dbus correctly. (fd.o #13194, Simon McVittie)
690 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
691 (fd.o #101315, Laurent Bigonville)
693 • Avoid deprecated API calls when using SELinux
694 (fd.o #100912, Laurent Bigonville)
696 • Switch a test from the deprecated g_test_trap_fork() to
697 g_test_trap_subprocess(), for Windows support and better robustness
698 on Unix (fd.o #101362, Simon McVittie)
700 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
701 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
702 This prevents the two files from going out of sync on stateless or live
703 images without needing to run dbus-uuidgen, and supports older D-Bus
704 implementations that do not necessarily read /etc/machine-id themselves.
705 (fd.o #101570, Simon McVittie)
707 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
708 abstract sockets. This is preferable when used with Linux containers.
709 (fd.o #101567, Simon McVittie)
713 • Fix a reference leak when blocking on a pending call on a connection
714 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
716 • Don't put timestamps in the Doxygen-generated documentation,
717 or hard-code the build directory into builds with embedded tests,
718 for reproducible builds (fd.o #100692, Simon McVittie)
720 • Fix some integration test issues (fd.o #100686, Simon McVittie)
722 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
724 • If we somehow get an autolaunch address with multiple semicolon-separated
725 components, and they don't work, don't invalidly "pile up" errors
726 (fd.o #101257, Simon McVittie)
730 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
731 (fd.o #100715, Simon McVittie)
733 D-Bus 1.11.12 (2017-04-07)
736 The “it's something humans do” release.
740 • The session dbus-daemon now supports transient .service files
741 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
742 service directories, this directory is not monitored with inotify
743 or similar, and the service files must be named exactly
744 ${bus_name}.service. (fd.o #99825, Simon McVittie)
746 • dbus can be configured with --enable-relocation when building with
747 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
748 to make the pkg-config metadata relocatable. This is useful for
749 non-standard prefixes, and in particular for Windows installations.
750 However, it is not recommended for system-wide installations into
751 /usr, because it interferes with pkg-config's ability to filter out
752 compiler default linker directories.
754 With Autotools, the default is --enable-relocation when building
755 for Windows or --disable-relocation otherwise. With CMake, the default
756 is -DDBUS_RELOCATABLE=ON.
758 (fd.o #99721; Ralf Habacker, Simon McVittie)
760 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
761 own FindDBus.cmake macros, whether dbus was compiled with Autotools
762 or with CMake. See the end of README.cmake for more information.
763 (fd.o #99721; Ralf Habacker, Simon McVittie)
767 • Always read service file directories in the intended order
768 (fd.o #99825, Simon McVittie)
770 • When tests are skipped, don't try to kill nonexistent process 0
771 (fd.o #99825, Simon McVittie)
773 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
775 • Fix a harmless read overflow and some memory leaks in a unit test
776 (fd.o #100568, Philip Withnall)
778 • Fix some typos in test code
779 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
781 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
782 in documentation (fd.o #99901, Philip Withnall)
784 • Fix and enable compiler warnings related to -Wswitch
785 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
787 • Fix writing off the end of a fd_set when testing with valgrind
788 (fd.o #99839, Philip Withnall)
790 D-Bus 1.11.10 (2017-02-16)
793 The “purple hair gives you telekinesis?” release.
797 • AppArmor support requires at least libapparmor 2.8.95, reduced
798 from 2.10 in previous versions. One test requires 2.10 and is
799 skipped if building with an older version.
803 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
804 stable and Debian testing in addition to the older Ubuntu that is
805 the default (fd.o #98889, Simon McVittie)
807 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
809 • Silence many -Wswitch-enum and -Wswitch-default warnings
810 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
812 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
813 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
815 • Install pkg-config metadata on Unix even if building with CMake
816 (fd.o #99752, Ralf Habacker)
818 • Exclude auth mechanisms from REJECTED message if they are supported
819 in the code but but configured to be disallowed (fd.o #99621,
824 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
825 allow an attacker to overwrite a file named "nonce", in a directory
826 that the user running dbus-daemon can write, with a random value
827 known only to the user running dbus-daemon. This is unlikely to be
828 exploitable in practice, particularly since the nonce-tcp transport
829 is really only useful on Windows.
831 On Unix systems we strongly recommend using only the unix: and systemd:
832 transports, together with EXTERNAL authentication. These are the only
833 transports and authentication mechanisms enabled by default.
835 (fd.o #99828, Simon McVittie)
837 • Avoid symlink attacks in the "embedded tests", which are not enabled
838 by default and should never be enabled in production builds of dbus.
839 (fd.o #99828, Simon McVittie)
841 • Fix the implementation of re-enabling a timeout so that its
842 countdown is restarted as intended, instead of continually
843 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
845 • When receiving a message with file descriptors, do not start reading
846 the beginning of the next message, so that only one such message
847 is processed at a time. In conjunction with the fix for #95619
848 this means that processes sending many file descriptors, such as
849 systemd-logind on a system that receives very rapid ssh connections,
850 are not treated as abusive and kicked off the bus. Revert the previous
851 workaround that special-cased uid 0.
852 (fd.o #95263, LP#1591411; Simon McVittie)
854 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
855 for Windows with CMake (fd.o #99586, Ralf Habacker)
857 • Do not set Unix-specific variables when targeting Windows
858 (fd.o #99586, Ralf Habacker)
860 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
861 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
863 • Use relative install locations in CMake on Unix to respect DESTDIR,
864 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
866 • Install dbus-arch-deps.h correctly when using CMake
867 (fd.o #99586, #99721; Ralf Habacker)
869 • Improve argument validation for `dbus-test-tool spam`
870 (ffd.o #99693, Coverity #54759; Philip Withnall)
872 • Don't shift by a negative integer if a hash table becomes monstrously
873 large (fd.o #99641, Coverity #54682; Philip Withnall)
875 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
876 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
878 • Remove an unnecessary NULL check
879 (fd.o #99642, Coverity #141062; Philip Withnall)
881 • Improve error handling in unit tests and dbus-send
882 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
883 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,
884 #54710, #54711, #54714, #54715, #54718, #54721, #54724, #54726,
885 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
887 • Do not print verbose messages' timestamps to stderr if the actual message
888 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
890 D-Bus 1.11.8 (2016-11-28)
893 The “panics in the face of breakfast foods” release.
895 Build-time configuration:
897 • The new --enable-debug configure option provides an easy way to
898 enable debug symbols, disable optimization and/or enable profiling.
900 • The --enable-compile-warnings configure option can be used to control
903 • The --disable-compiler-optimisations configure option is no longer
904 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
908 • D-Bus Specification version 0.30
909 · Define the jargon term "activation" more clearly
910 · Define the jargon term "auto-starting", which is one form of activation
911 · Document the optional SystemdService key in service files
912 · Use versioned interface and bus names in most examples
913 · Clarify intended behaviour of Properties.GetAll
914 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
916 • Fix and enable a lot of compiler warnings to improve future code
917 quality. This might incidentally also fix some environment variable
919 · In particular, printf-style functions in the libdbus API are now annotated
920 with __attribute__((__format__(__printf__, *, *))) when compiling with
921 gcc or clang. This might make printf bugs in other software visible
923 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
924 Thomas Zimmermann, Simon McVittie)
926 • When running with AppArmor mediation (for example using Ubuntu's patched
927 Linux kernel), clients can no longer auto-start services unless they would
928 have been able to send the auto-starting message to the service after it
929 starts. StartServiceByName() is unaffected, and continues to be allowed by
930 default in AppArmor's <abstractions/dbus-strict> and
931 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
935 • Work around an undesired effect of the fix for CVE-2014-3637
936 (fd.o #80559), in which processes that frequently send fds, such as
937 logind during a flood of new PAM sessions, can get disconnected for
938 continuously having at least one fd "in flight" for too long;
939 dbus-daemon interprets that as a potential denial of service attack.
940 The workaround is to disable that check for uid 0 process such as
941 logind, with a message in the system log. The bug remains open while
942 we look for a more general solution.
943 (fd.o #95263, LP#1591411; Simon McVittie)
945 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
946 was disabled at compile time. That test is not expected to work
947 in that configuration. (fd.o #98665, Simon McVittie)
949 D-Bus 1.11.6 (2016-10-10)
952 The “darkly whimsical” release.
956 • Do not treat ActivationFailure message received from root-owned systemd
957 name as a format string. In principle this is a security vulnerability,
958 but we do not believe it is exploitable in practice, because only
959 privileged processes can own the org.freedesktop.systemd1 bus name, and
960 systemd does not appear to send activation failures that contain "%".
962 Please note that this probably *was* exploitable in dbus versions
963 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
964 the time was only thought to be a denial of service vulnerability
965 (CVE-2015-0245). If you are still running one of those versions,
966 patch or upgrade immediately.
968 (fd.o #98157, Simon McVittie)
972 • D-Bus Specification version 0.29
973 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
974 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
976 • Log to syslog when we exceed various anti-DoS limits, and add test
977 coverage for them (fd.o #86442, Simon McVittie)
979 • Improve syslog handling so that _dbus_warn() and similar warnings
980 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
981 and log to syslog (instead of /dev/null) when dbus-daemon is started by
982 dbus-launch. (fd.o #97009, Simon McVittie)
984 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
985 (fd.o #89011, Philip Withnall)
987 • When logging messages about service activation, mention which peer
988 requested the activation (fd.o #68212, Philip Withnall)
990 • On Linux, mention the LSM label (if available) whenever we print
991 debug information about a peer (fd.o #68212, Philip Withnall)
995 • Harden dbus-daemon against malicious or incorrect ActivationFailure
996 messages by rejecting them if they do not come from a privileged
997 process, or if systemd activation is not enabled
998 (fd.o #98157, Simon McVittie)
1000 • Avoid undefined behaviour when setting reply serial number without going
1001 via union DBusBasicValue (fd.o #98035, Marc Mutz)
1003 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
1004 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
1006 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
1008 D-Bus 1.11.4 (2016-08-15)
1011 The “copper pickaxe” release.
1015 • Building from git (but not from tarballs) now requires
1016 macros from the GNU Autoconf Archive, for example the autoconf-archive
1017 package in Debian or Fedora derivatives.
1019 Build-time configuration:
1021 • The option to enable coverage instrumentation has changed from
1022 --enable-compiler-coverage to --enable-code-coverage.
1026 • D-Bus Specification version 0.28
1027 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
1029 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
1030 minimizing failed connections under heavy load
1031 (fd.o #95264, Lennart Poettering)
1033 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
1035 • Use the same regression tests for subprocess starting on Unix and Windows
1036 (fd.o #95191, Ralf Habacker)
1038 • Print timestamps and thread IDs in verbose messages
1039 (fd.o #95191, Ralf Habacker)
1041 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
1042 pointing to /dev/null (fd.o #97008, Simon McVittie)
1044 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
1045 (fd.o #88922, Thomas Zimmermann)
1049 • On Windows, fix a memory leak in replacing the installation prefix
1050 (fd.o #95191, Ralf Habacker)
1052 • On Linux, when dbus-daemon is run with reduced susceptibility to the
1053 OOM killer (typically via systemd), do not let child processes inherit
1054 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
1056 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
1057 even if a parent process incorrectly starts them with stdin, stdout
1058 and/or stderr closed (fd.o #97008, Simon McVittie)
1060 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
1061 contains a semicolon (fd.o #94746, Thiago Macieira)
1063 • Fix memory leaks and thread safety in subprocess starting on Windows
1064 (fd.o #95191, Ralf Habacker)
1066 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
1067 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
1069 • In tests that exercise correct handling of crashing D-Bus services,
1070 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
1072 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
1074 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
1075 in some test cases (fd.o #93909, Nick Lewycky)
1077 • Add assertions to reassure a static analysis tool
1078 (fd.o #93210, Deepika Aggarwal)
1080 • Be explicit about enum comparison when loading XML
1081 (fd.o #93205, Deepika Aggarwal)
1083 • update-activation-environment: produce better diagnostics on error
1084 (fd.o #96653, Simon McVittie)
1086 • Avoid various compiler warnings with gcc 6
1087 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
1089 • On Unix when configured to use the system log, report as "dbus-daemon",
1090 not as "dbus" (fd.o #97009, Simon McVittie)
1092 • During unit tests, reduce the amount we write to the system log
1093 (fd.o #97009, Simon McVittie)
1095 D-Bus 1.11.2 (2016-03-07)
1098 The “pneumatic drill vs. Iron Maiden” release.
1102 • Enable "large file support" on systems where it exists: dbus-daemon
1103 is not expected to open large files, but it might need to stat files
1104 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
1106 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
1107 which might result in a pedantic C compiler not copying the entire contents
1108 of a DBusMessageIter; statically assert that this is not an ABI change
1109 in practice (fd.o #94136, Simon McVittie)
1111 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
1112 (fd.o #94244, Dmitri Iouchtchenko)
1114 • Correctly report test failures in C tests from run-test.sh
1115 (fd.o #93379; amit tewari, Simon McVittie)
1117 • When tests are enabled, run all the marshal-validate tests, not just
1118 the even-numbered ones (fd.o #93908, Nick Lewycky)
1120 • Correct the expected error from one marshal-validate test, which was
1121 previously not run due to the above bug (fd.o #93908, Simon McVittie)
1123 • Fix compilation under CMake when embedded tests are disabled
1124 (fd.o #94094, eric.hyer)
1128 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
1129 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
1131 • When building with CMake, use the same gcc/clang warnings as under Autotools,
1132 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
1134 • test/name-test: make C tests produce TAP output and run them directly, not
1135 via run-test.sh (fd.o #92899, Simon McVittie)
1137 • Under CMake when cross-compiling for Windows on Unix, run the tests
1138 under Wine even if binfmt_misc support is not available
1139 (fd.o #88966, Ralf Habacker)
1141 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
1142 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
1144 • Factor out some functions that will be needed in future for a Windows
1145 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
1147 D-Bus 1.11.0 (2015-12-02)
1150 The “peppermint deer” release.
1154 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
1155 C99 constants such as PRId64 and PRIu64.
1159 • D-Bus Specification version 0.27
1160 · Specify that services should not reply if NO_REPLY_EXPECTED was used
1161 (fd.o #75749, Lars Uebernickel)
1163 • Add a script to do continuous-integration builds, and metadata to run it
1164 on travis-ci.org. To use this, clone the dbus git repository on GitHub
1165 and set it up with travis-ci.org; the only special setting needed is
1166 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
1168 • If dbus-daemon is run with --systemd-activation, do not require
1169 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
1173 • Re-order dbus-daemon startup so that on SELinux systems, the thread
1174 that reads AVC notifications retains the ability to write to the
1175 audit log (fd.o #92832, Laurent Bigonville)
1177 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
1179 • When using the Monitoring interface, match messages' destinations
1180 (fd.o #92074, Simon McVittie)
1182 • On Linux with systemd, stop installing a reference to the obsolete
1183 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
1186 • On Windows, when including configuration files with <include> or
1187 <includedir>, apply the same relocation as for the Exec paths
1188 in .service files (fd.o #92028, Simon McVittie)
1190 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
1192 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
1194 D-Bus 1.10.6 (2015-12-01)
1197 The “marzipan beetles” release.
1201 • On Unix when running tests as root, don't assert that root and
1202 the dbus-daemon user can still call UpdateActivationEnvironment;
1203 assert that those privileged users can call BecomeMonitor instead
1204 (fd.o #93036, Simon McVittie)
1206 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
1209 • On Windows Autotools builds, don't run tests that rely on
1210 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
1212 D-Bus 1.10.4 (2015-11-17)
1215 The “Frostburn Canyon” release.
1219 • GetConnectionCredentials, GetConnectionUnixUser and
1220 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
1221 will now return details of the dbus-daemon itself. This is required
1222 to be able to call SetEnvironment on systemd.
1223 (fd.o #92857, Jan Alexander Steffens)
1227 • Make UpdateActivationEnvironment always fail with AccessDenied on the
1228 system bus. Previously, it was possible to configure it so root could
1229 call it, but the environment variables were not actually used,
1230 because the launch helper would discard them.
1231 (fd.o #92857, Jan Alexander Steffens)
1233 • On Unix with --systemd-activation on a user bus, make
1234 UpdateActivationEnvironment pass on its arguments to systemd's
1235 SetEnvironment method, solving inconsistency between the environments
1236 used for traditional activation and systemd user-service activation.
1237 (fd.o #92857, Jan Alexander Steffens)
1239 • On Windows, don't crash if <syslog/> or --syslog is used
1240 (fd.o #92538, Ralf Habacker)
1242 • On Windows, fix a memory leak when setting a DBusError from a Windows
1243 error (fd.o #92721, Ralf Habacker)
1245 • On Windows, don't go into infinite recursion if we abort the process
1246 with backtraces enabled (fd.o #92721, Ralf Habacker)
1248 • Fix various failing tests, variously on Windows and cross-platform:
1249 · don't test system.conf features (users, groups) that only make sense
1250 on the system bus, which is not supported on Windows
1251 · don't call _dbus_warn() when we skip a test, since it is fatal
1252 · fix computation of expected <standard_session_servicedirs/>
1253 · when running TAP tests, translate newlines to Unix format, fixing
1254 cross-compiled tests under Wine on Linux
1255 · don't stress-test refcounting under Wine, where it's really slow
1256 · stop assuming that a message looped-back to the test will be received
1258 · skip some system bus tests on Windows since they make no sense there
1259 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
1261 D-Bus 1.10.2 (2015-10-26)
1264 The “worst pies in London” release.
1268 • Correct error handling for activation: if there are multiple attempts
1269 to activate the same service and it fails immediately, the first attempt
1270 would get the correct reply, but the rest would time out. We now send
1271 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
1273 • If BecomeMonitor is called with a syntactically invalid match rule,
1274 don't crash with an assertion failure, fixing a regression in 1.9.10.
1275 This was not exploitable as a denial of service, because the check
1276 for a privileged user is done first. (fd.o #92298, Simon McVittie)
1278 • On Linux with --enable-user-session, add the bus address to the
1279 environment of systemd services for better backwards compatibility
1280 (fd.o #92612, Jan Alexander Steffens)
1282 • On Windows, fix the logic for replacing the installation prefix
1283 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
1285 • On Windows, if installed in the conventional layout with ${prefix}/etc
1286 and ${prefix}/share, use relative paths between bus configuration files
1287 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
1289 • Make more of the regression tests pass in Windows builds (fd.o #92538,
1292 D-Bus 1.10.0 (2015-08-25)
1297 This is a new stable branch, recommended for use in OS distributions.
1301 • distribute test/tap-test.sh.in, even if the tarball was built without
1302 tests enabled (fd.o #91684, Simon McVittie)
1303 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
1305 Summary of major changes since 1.8.0:
1307 • The basic setup for the well-known system and session buses is
1308 now done in read-only files in ${datadir} (normally /usr/share).
1309 See the NEWS entry for 1.9.18 for details.
1311 • AppArmor integration has been merged, with features similar to the
1312 pre-existing SELinux integration. It is mostly compatible with the
1313 patches previously shipped by Ubuntu, with one significant change:
1314 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
1315 by GetConnectionCredentials and was not included.
1317 • The --enable-user-session configure option can be enabled
1318 by OS integrators intending to use systemd to provide a session bus
1319 per user (in effect, treating all concurrent graphical and non-graphical
1320 login sessions as one large session).
1322 • The new listenable address mode "unix:runtime=yes" listens on
1323 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
1324 user session. libdbus and "dbus-launch --autolaunch" will connect to
1325 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
1328 • All executables are now dynamically linked to libdbus-1.
1329 Previously, some executables, most notably dbus-daemon, were statically
1330 linked to a specially-compiled variant of libdbus. This results in
1331 various private functions in the _dbus namespace being exposed by the
1332 shared library. These are not API, and must not be used outside
1333 the dbus source tree.
1335 • On platforms with ELF symbol versioning, all public symbols
1336 are versioned LIBDBUS_1_3.
1340 • org.freedesktop.DBus.GetConnectionCredentials returns
1341 LinuxSecurityLabel where supported
1342 • org.freedesktop.DBus.Monitoring interface (privileged)
1343 · BecomeMonitor method supersedes match rules with eavesdrop=true,
1344 which are now deprecated
1345 • org.freedesktop.DBus.Stats interface (semi-privileged)
1346 · now enabled by default
1347 · new GetAllMatchRules method
1348 • org.freedesktop.DBus.Verbose interface (not normally compiled)
1349 · toggles the effect of DBUS_VERBOSE
1354 • dbus-update-activation-environment
1356 New optional dependencies:
1358 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
1359 • Complete documentation requires Ducktype and yelp-tools
1360 • Full test coverage requires GLib 2.36 and PyGI
1361 • AppArmor integration requires libapparmor and optionally libaudit
1363 Dependencies removed:
1367 D-Bus 1.9.20 (2015-08-06)
1370 The “Remember Tomorrow” release.
1372 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
1377 • Don't second-guess what the ABI of poll() is, allowing it to be used
1378 on Integrity RTOS and other unusual platforms (fd.o #90314;
1379 Rolland Dudemaine, Simon McVittie)
1381 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
1382 both enabled (fd.o #89225, Simon McVittie)
1384 • Log audit events for AppArmor/SELinux policy violations whenever
1385 we have CAP_AUDIT_WRITE, even if not the system bus
1386 (fd.o #83856, Laurent Bigonville)
1388 D-Bus 1.9.18 (2015-07-21)
1391 The “Pirate Elite” release.
1393 Configuration changes:
1395 • The basic setup for the well-known system and session buses is now done
1396 in read-only files in ${datadir}, moving a step closer to systems
1397 that can operate with an empty /etc directory. In increasing order
1400 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
1401 the default message policies.
1402 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
1403 dbus still installs a trivial version of each, for documentation
1404 purposes; putting configuration directives in these files is deprecated.
1405 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
1406 to install "drop-in" configuration snippets (any packages
1407 using those directories should explicitly depend on at least this
1409 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
1410 or third-party software to install "drop-in" configuration snippets
1411 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
1414 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
1415 and "s*" refers to either system or session as appropriate.
1417 (fd.o #89280, Dimitri John Ledkov)
1421 • Fix a memory leak when GetConnectionCredentials() succeeds
1422 (fd.o #91008, Jacek Bukarewicz)
1424 • Ensure that dbus-monitor does not reply to messages intended for others,
1425 resulting in its own disconnection (fd.o #90952, Simon McVittie)
1427 D-Bus 1.9.16 (2015-05-14)
1430 The “titanium barns” release.
1434 • Automake 1.13 is now required when compiling from git or modifying
1439 • On Unix platforms, change the default configuration for the session bus
1440 to only allow EXTERNAL authentication (secure kernel-mediated
1441 credentials-passing), as was already done for the system bus.
1443 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
1444 unpredictable pseudo-random numbers.
1446 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
1447 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1448 NFS or similar, you will need to reconfigure the session bus to accept
1449 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1452 (fd.o #90414, Simon McVittie)
1454 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1455 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1456 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1457 occurs, instead of silently falling back to low-entropy pseudorandom
1458 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1462 • Add dbus_message_iter_get_element_count()
1463 (fd.o #30350; Christian Dywan, Simon McVittie)
1465 • Introduce new internal DBusSocket and DBusPollable types so we can
1466 stop treating the Windows SOCKET type as if it was int. DBusSocket
1467 is specifically a socket, cross-platform. DBusPollable is whatever
1468 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1469 (fd.o #89444; Ralf Habacker, Simon McVittie)
1471 • All regression tests now output TAP <https://testanything.org/>
1472 (fd.o #89846, Simon McVittie)
1474 • Internal APIs consistently use signed values for timestamps
1475 (fd.o #18494, Peter McCurdy)
1477 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1478 (fd.o #88812, Simon McVittie)
1480 • Clean up a lot of compiler warnings
1481 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1485 • Add locking to DBusCounter's reference count and notify function
1486 (fd.o #89297, Adrian Szyndela)
1488 • Ensure that DBusTransport's reference count is protected by the
1489 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1491 • Correctly release DBusServer mutex before early-return if we run out
1492 of memory while copying authentication mechanisms (fd.o #90021,
1495 • Make dbus-test-tool and dbus-update-activation-environment portable
1496 to Windows (fd.o #90089, Ralf Habacker)
1498 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1499 Ralf Habacker, Simon McVittie)
1501 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1504 • Clean up some memory and fd leaks in test code and tools
1505 (fd.o #90021, Ralf Habacker)
1507 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1508 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1510 • CMake generates a versioned shared library even if the revision is 0,
1511 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1513 D-Bus 1.9.14 (2015-03-02)
1516 The “don't stand in the poison cloud” release.
1520 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1521 were previously linked to a static version of libdbus.
1523 • The tests no longer require dbus-glib in order to exercise the libdbus
1524 shared library; they are always linked to libdbus now.
1526 Build-time configuration:
1528 • The new --enable-user-session option, off by default, can be enabled
1529 by OS integrators intending to use systemd to provide a session bus
1530 per user (in effect, treating all concurrent graphical and non-graphical
1531 login sessions as one large session)
1535 • All executables are now linked dynamically to libdbus.
1536 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1538 • On platforms that support them (GNU libc and possibly others),
1539 libdbus now has versioned symbols for its public API.
1540 All public symbols (visible in the header files) are currently
1541 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1542 dbus_internal have a version that changes with each release, and
1543 must not be used by applications. (also fd.o #83115)
1545 • New listenable address mode "unix:runtime=yes" which listens on
1546 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1547 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1549 • Add optional systemd units for a per-user bus listening on
1550 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1552 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1553 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1556 • New dbus-update-activation-environment tool uploads environment
1557 variables to "dbus-daemon --session" and optionally "systemd --user",
1558 primarily as a way to keep the per-user bus compatible with
1559 distributions' existing X11 login scripts (also fd.o #61301)
1561 • <includedir/> elements in dbus-daemon configuration are now silently
1562 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1564 • Add microsecond-resolution timestamps to the default output of
1565 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1569 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1570 (fd.o #89222, Simon McVittie)
1572 D-Bus 1.9.12 (2015-02-19)
1575 The “monster lasagna” release.
1579 • Ducktype and yelp-tools are now required to build complete documentation
1580 (they are optional for normal builds).
1584 • D-Bus Specification version 0.26
1585 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1586 · document the BecomeMonitor method
1588 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1589 (fd.o #89041; Tyler Hicks, Simon McVittie)
1591 • On Linux, add support for AppArmor mediation of message sending and
1592 receiving and name ownership (paralleling existing SELinux mediation
1593 support), and eavesdropping (a new check, currently AppArmor-specific)
1594 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1596 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1597 that have printable ASCII contents; we previously only did this for
1598 unterminated bytestrings (fd.o #89109, Simon McVittie)
1600 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1602 • On Windows, add WindowsSID to GetConnectionCredentials
1603 (fd.o #54445, Ralf Habacker)
1605 • Improve clarity of dbus-monitor --profile output and add more columns
1606 (fd.o #89165, Ralf Habacker)
1608 • Add a man page for dbus-test-tool, and build it under CMake as well
1609 as Autotools (fd.o#89086, Simon McVittie)
1611 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1612 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1613 (fd.o #88896, Ralf Habacker)
1617 • Reduce the number of file descriptors used in the fd-passing test,
1618 avoiding failure under the default Linux fd limit, and automatically
1619 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1621 D-Bus 1.9.10 (2015-02-09)
1624 The “sad cyborgs” release.
1626 Security fixes merged from 1.8.16:
1628 • Do not allow non-uid-0 processes to send forged ActivationFailure
1629 messages. On Linux systems with systemd activation, this would
1630 allow a local denial of service: unprivileged processes could
1631 flood the bus with these forged messages, winning the race with
1632 the actual service activation and causing an error reply
1633 to be sent back when service auto-activation was requested.
1634 This does not prevent the real service from being started,
1635 so the attack only works while the real service is not running.
1636 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1640 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1641 similar tools receive messages without altering the security properties
1642 of the system bus, by calling the new BecomeMonitor method on a
1643 private connection. This bypasses the normal <allow> and <deny> rules
1644 entirely, so to preserve normal message-privacy assumptions, only root
1645 is allowed to do this on the system bus. Restricted environments,
1646 such as Linux with LSMs, should lock down access to the Monitoring
1647 interface. (fd.o #46787, Simon McVittie)
1649 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1650 dbus-daemon supports it and access permissions allow it.
1651 It still supports the previous approach ("eavesdropping" match rules)
1652 for compatibility with older bus daemons. (fd.o #46787, Simon)
1654 • dbus-monitor can now log the message stream as binary data for later
1655 analysis, with either no extra framing beyond the normal D-Bus headers,
1656 or libpcap-compatible framing treating each D-Bus message
1657 as a captured packet. (fd.o #46787, Simon)
1661 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1663 • On Unix, forcibly terminate regression tests after 60 seconds to
1664 prevent them from blocking continuous integration frameworks
1665 (fd.o #46787, Simon)
1667 D-Bus 1.9.8 (2015-02-03)
1670 The “all the types of precipitation” release.
1674 • full test coverage now requires GLib 2.36
1675 • full test coverage now requires PyGI (PyGObject 3,
1676 "import gi.repository.GObject") instead of the
1677 obsolete PyGObject 2 ("import gobject")
1681 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1683 • better regression test coverage, including systemd activation
1684 (fd.o #57952, #88810; Simon McVittie)
1688 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1689 turned off (fd.o #88808, Simon McVittie)
1691 • TCP sockets on Windows no longer fail to listen approximately 1 time
1692 in 256, caused by a logic error that should have always made it fail but
1693 was mitigated by incorrect endianness for the port number
1694 (fd.o #87999, Ralf Habacker)
1696 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1698 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1699 previous 64, completing a previous fix which only worked under
1700 Autotools (fd.o #71297, Ralf Habacker)
1702 • on Windows, if the IP family is unspecified only use IPv4,
1703 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1705 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1707 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1709 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1712 D-Bus 1.9.6 (2015-01-05)
1715 The “I do have a bread knife” release.
1719 • Do not allow calls to UpdateActivationEnvironment from uids other than
1720 the uid of the dbus-daemon. If a system service installs unsafe
1721 security policy rules that allow arbitrary method calls
1722 (such as CVE-2014-8148) then this prevents memory consumption and
1723 possible privilege escalation via UpdateActivationEnvironment.
1725 We believe that in practice, privilege escalation here is avoided
1726 by dbus-daemon-launch-helper sanitizing its environment; but
1727 it seems better to be safe.
1729 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1730 on object paths other than /org/freedesktop/DBus. Some system services
1731 install unsafe security policy rules that allow arbitrary method calls
1732 to any destination, method and interface with a specified object path;
1733 while less bad than allowing arbitrary method calls, these security
1734 policies are still harmful, since dbus-daemon normally offers the
1735 same API on all object paths and other system services might behave
1740 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1741 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1743 D-Bus 1.9.4 (2014-11-24)
1746 The “extra-sturdy caramel” release.
1750 • Partially revert the CVE-2014-3639 patch by increasing the default
1751 authentication timeout on the system bus from 5 seconds back to 30
1752 seconds, since this has been reported to cause boot regressions for
1753 some users, mostly with parallel boot (systemd) on slower hardware.
1755 On fast systems where local users are considered particularly hostile,
1756 administrators can return to the 5 second timeout (or any other value
1757 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1760 <limit name="auth_timeout">5000</limit>
1763 (fd.o #86431, Simon McVittie)
1765 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1766 (fd.o #86431, Simon McVittie)
1768 • Send back an AccessDenied error if the addressed recipient is not allowed
1769 to receive a message (and in builds with assertions enabled, don't
1770 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1772 D-Bus 1.9.2 (2014-11-10)
1775 The “structurally unsound flapjack” release.
1779 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1780 so that CVE-2014-3636 part A cannot exhaust the system bus'
1781 file descriptors, completing the incomplete fix in 1.8.8.
1782 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1786 • D-Bus Specification version 0.25
1787 · new value 'const' for EmitsChangedSignal annotation

1789 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1790 (fd.o #83449; Lennart Poettering, Simon McVittie)
1791 · annotate table of types with reserved/basic/container, and for
1792 basic types, fixed/string-like
1793 · clarify arbitrary limits by quoting them in mebibytes
1795 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1796 (fd.o #83449, Simon McVittie)
1798 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1799 useful for debugging and performance testing:
1800 · dbus-test-tool spam: send repeated messages
1801 · dbus-test-tool echo: send an empty reply for all method calls
1802 · dbus-test-tool black-hole: do not reply to method calls
1803 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1805 • Add support for process ID in credentials-passing on NetBSD
1806 (fd.o #69702, Patrick Welche)
1808 • Add an example script to find potentially undesired match rules
1809 (fd.o #84598, Alban Crequy)
1811 • Document the central assumption that makes our use of credentials-passing
1812 secure (fd.o #83499, Simon McVittie)
1814 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1815 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1820 • Use a less confusing NoReply message when disconnected with a reply pending
1821 (fd.o #76112, Simon McVittie)
1823 • Make the .pc file relocatable by letting pkg-config do all variable
1824 expansion itself (fd.o #75858, Руслан Ижбулатов)
1826 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1827 (fd.o #85563, Patrick Welche)
1829 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1831 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1832 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1834 • Do not fail the tests if a parent process has leaked non-close-on-exec
1835 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1837 • Do not fail the tests on Unix platforms with incomplete
1838 credentials-passing support, but do fail if we can't pass credentials
1839 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1840 (fd.o #69702, Simon McVittie)
1842 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1843 when building with cmake, and expand test coverage there
1844 (fd.o #73689; Ralf Habacker, Simon McVittie)
1846 D-Bus 1.9.0 (2014-10-01)
1849 The “tiered cheeses” release.
1853 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1854 requires either the libsystemd or libsd-daemon shared library, dropping the
1855 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1857 Build-time configuration changes:
1859 • The Stats interface is now enabled by default, and locked-down to
1860 root-only on the system bus. Configure with --disable-stats
1861 to disable it altogether on memory- or disk-constrained systems,
1862 or see ${docdir}/examples/ to open it up to non-root users on the
1863 system bus or restrict access on the session bus.
1864 (fd.o #80759; Simon McVittie, Alban Crequy)
1866 • The CMake build system now builds the same shared library name as Autotools
1867 on at least Linux and Windows:
1868 - on Linux (and perhaps other Unix platforms), it previously built
1869 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1870 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1871 - on Windows, it previously built either libdbus-1.dll (release) or
1872 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1873 libdbus-1.dll for compatibility with older applications.
1874 (fd.o #74117, Ralf Habacker)
1878 • D-Bus Specification version 0.24
1879 · document how to quote match rules (fd.o #24307, Simon McVittie)
1880 · explicitly say that most message types never expect a reply
1881 regardles of whether they have NO_REPLY_EXPECTED
1882 (fd.o #75749, Simon McVittie)
1884 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
1885 initial latency (fd.o #75544, Matt Hoosier)
1887 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
1888 (fd.o #69702, Patrick Welche)
1890 • in dbus-monitor, print more information about file descriptors
1891 (fd.o #80603, Alban Crequy)
1893 • do not install system bus configuration if built for Windows
1894 (fd.o #83583; Ralf Habacker, Simon McVittie)
1896 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
1898 • Add a regression test for file descriptor passing (fd.o #83622,
1903 • fix an incorrect error message if a Unix socket path is too long
1904 (fd.o #73887, Antoine Jacoutot)
1906 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
1907 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
1909 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
1910 in ps(1) (fd.o #69716, Chengwei Yang)
1912 • avoid calling poll() with timeout < -1, which is considered invalid
1913 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
1915 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
1916 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
1917 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
1919 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
1921 • Documentation improvements
1922 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
1924 • in dbus-monitor, do not leak file descriptors that we have monitored
1925 (fd.o #80603, Alban Crequy)
1927 • Set the close-on-exec flag for the inotify file descriptor, even
1928 if built with CMake or older libc (fd.o #73689, Simon McVittie)
1930 • Remove some LGPL code from the Windows dbus-daemon
1931 (fd.o #57272, Ralf Habacker)
1933 D-Bus 1.8.8 (2014-09-16)
1936 The "smashy smashy egg man" release.
1940 • Do not accept an extra fd in the padding of a cmsg message, which
1941 could lead to a 4-byte heap buffer overrun.
1942 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1944 • Reduce default for maximum Unix file descriptors passed per message
1945 from 1024 to 16, preventing a uid with the default maximum number of
1946 connections from exhausting the system bus' file descriptors under
1947 Linux's default rlimit. Distributors or system administrators with a
1948 more restrictive fd limit may wish to reduce these limits further.
1950 Additionally, on Linux this prevents a second denial of service
1951 in which the dbus-daemon can be made to exceed the maximum number
1952 of fds per sendmsg() and disconnect the process that would have
1954 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1956 • Disconnect connections that still have a fd pending unmarshalling after
1957 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1958 removing the possibility of creating an abusive connection that cannot be
1959 disconnected by setting up a circular reference to a connection's
1961 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1963 • Reduce default for maximum pending replies per connection from 8192 to 128,
1964 mitigating an algorithmic complexity denial-of-service attack
1965 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1967 • Reduce default for authentication timeout on the system bus from
1968 30 seconds to 5 seconds, avoiding denial of service by using up
1969 all unauthenticated connection slots; and when all unauthenticated
1970 connection slots are used up, make new connection attempts block
1971 instead of disconnecting them.
1972 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1976 • Check for libsystemd from systemd >= 209, falling back to
1977 the older separate libraries if not found (Umut Tezduyar Lindskog,
1980 • On Linux, use prctl() to disable core dumps from a test executable
1981 that deliberately raises SIGSEGV to test dbus-daemon's handling
1982 of that condition (fd.o #83772, Simon McVittie)
1984 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
1987 • Improve documentation for running tests on Windows (fd.o #41252,
1990 D-Bus 1.8.6 (2014-06-02)
1995 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1996 the message. This prevents an attack in which a malicious client can
1997 make dbus-daemon disconnect a system service, which is a local
1999 (fd.o #80163, CVE-2014-3532; Alban Crequy)
2001 • Track remaining Unix file descriptors correctly when more than one
2002 message in quick succession contains fds. This prevents another attack
2003 in which a malicious client can make dbus-daemon disconnect a system
2005 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
2006 Simon McVittie, Alban Crequy)
2010 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
2011 attach to a session, kill the dbus-daemon as intended
2012 (fd.o #74698, Роман Донченко)
2014 D-Bus 1.8.4 (2014-06-10)
2019 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
2020 flaw in dbus-daemon, part of the reference implementation of D-Bus.
2021 Additionally, in highly unusual environments the same flaw could lead to
2022 a side channel between processes that should not be able to communicate.
2023 (CVE-2014-3477, fd.o #78979)
2025 D-Bus 1.8.2 (2014-04-30)
2028 The “nobody wants red” release.
2032 • in the CMake build system, add some hints for Linux users cross-compiling
2033 Windows D-Bus binaries to be able to run tests under Wine
2034 (fd.o #41252, Ralf Habacker)
2036 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
2040 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
2041 to /var/lib/dbus/machine-id instead of generating an entirely new ID
2042 (fd.o #77941, Simon McVittie)
2044 • if dbus-launch receives an X error very quickly, do not kill
2045 unrelated processes (fd.o #74698, Роман Донченко)
2047 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
2048 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
2050 • cope with \r\n newlines in regression tests, since on Windows,
2051 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
2053 D-Bus 1.8.0 (2014-01-20)
2056 The “Wolverine distrusts my printer” release.
2058 This starts a new stable branch. The 1.6.x branch is now considered to be
2059 outdated, and will only receive fixes for serious bugs such as security
2060 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
2061 are unlikely to get any more releases, but if distributors still need to
2062 support them, please share security patches via upstream.
2064 Summary of changes since 1.6.x:
2066 • libdbus always behaves as if dbus_threads_init_default() had been called
2067 (thread-safety by default)
2068 • new dbus-run-session tool, replacing certain misuses of dbus-launch
2069 • dbus-monitor can talk to outdated versions of dbus-daemon again
2070 • new org.freedesktop.DBus.GetConnectionCredentials method
2071 • GetConnectionUnixProcessID also works correctly on Windows, returning
2072 the Windows process ID
2073 • GetConnectionWindowsSID returns the correct SID on Windows
2074 • expat is required, libxml2 can no longer be used as a substitute
2075 • the userDB cache is required, and cannot be disabled
2076 • a 64-bit integer type (either int, long, long long or _int64) is required
2077 • better systemd-journald integration on Linux
2078 • fixed long-standing fd and array leaks when failing to parse a message
2079 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
2080 when using certain object-path allocation patterns, notably in Avahi
2081 • better defaults for Windows support
2082 • better CMake support
2083 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
2084 • the source language for the man pages is now Docbook XML
2086 Enhancements since 1.7.10:
2088 • Enhance the CMake build system to check for GLib and compile/run
2089 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
2093 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
2096 • fix compilation of systemd journal support on older systemd versions where
2097 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
2099 • fix compilation on older MSVC versions by including stdlib.h
2100 (fd.o #73455, Ralf Habacker)
2102 • Allow <allow_anonymous/> to appear in an included configuration file
2103 (fd.o #73475, Matt Hoosier)
2105 Test behaviour changes since 1.7.10:
2107 • If the tests crash with an assertion failure, they no longer default to
2108 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
2109 environment if you want the old behaviour.
2111 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
2112 can be run with an external dbus-daemon by setting
2113 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
2114 an unusually-configured dbus-daemon are skipped.
2116 D-Bus 1.7.10 (2014-01-06)
2119 The “weighted companion cube” release.
2121 This is a release candidate for D-Bus 1.8.
2123 D-Bus Specification 0.23:
2125 • don't require messages with no INTERFACE to be dispatched
2126 (fd.o #68597, Simon McVittie)
2128 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
2131 • define "listenable" and "connectable" addresses, and discuss
2132 the difference (fd.o #61303, Simon McVittie)
2136 • support printing Unix file descriptors in dbus-send, dbus-monitor
2137 (fd.o #70592, Robert Ancell)
2139 • don't install systemd units if --disable-systemd is given
2140 (fd.o #71818, Chengwei Yang)
2144 • don't leak memory on out-of-memory while listing activatable or
2145 active services (fd.o #71526, Radoslaw Pajak)
2147 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
2149 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
2151 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
2152 and DBUS__SEND_MSG are numerically equal to their values in the
2153 reference policy (fd.o #88719, osmond sun)
2155 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
2156 (fd.o #71366, Matt Fischer)
2158 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
2159 winsock2.h (fd.o #71405, Matt Fischer)
2161 • do not return failure from _dbus_read_nonce() with no error set,
2162 preventing a potential crash (fd.o #72298, Chengwei Yang)
2164 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
2165 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
2167 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
2168 which doesn't do anything anyway on at least Linux and FreeBSD
2169 (fd.o #69492, Simon McVittie)
2171 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
2172 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
2173 for credentials more correctly (fd.o #69492, Simon McVittie)
2175 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
2176 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
2179 • refresh cached policy rules for existing connections when bus
2180 configuration changes (fd.o #39463, Chengwei Yang)
2182 D-Bus 1.7.8 (2013-11-01)
2185 The “extreme hills” release.
2189 • If systemd support is enabled, libsystemd-journal is now required.
2193 • When activating a non-systemd service under systemd, annotate its
2194 stdout/stderr with its bus name in the Journal. Known limitation:
2195 because the socket is opened before forking, the process will still be
2196 logged as if it had dbus-daemon's process ID and user ID.
2197 (fd.o #68559, Chengwei Yang)
2199 • Document more configuration elements in dbus-daemon(1)
2200 (fd.o #69125, Chengwei Yang)
2204 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
2205 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
2207 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
2208 disallowed method calls to the audit log, fixing a regression in 1.7.6
2209 (fd.o #49062, Colin Walters)
2211 • path_namespace='/' in match rules incorrectly matched nothing; it
2212 now matches everything. (fd.o #70799, Simon McVittie)
2214 D-Bus 1.7.6 (2013-10-09)
2217 The “CSI Shrewsbury” release.
2219 Build-time configuration changes:
2221 • Directory change notification via dnotify on Linux is no longer
2222 supported; it hadn't compiled successfully since 2010 in any case.
2223 If you don't have inotify (Linux) or kqueue (*BSD), you will need
2224 to send SIGHUP to the dbus-daemon when its configuration changes.
2225 (fd.o #33001, Chengwei Yang)
2227 • Compiling with --disable-userdb-cache is no longer supported;
2228 it didn't work since at least 2008, and would lead to an extremely
2229 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
2232 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
2233 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
2234 with the Autotools build system. (fd.o #66142, Chengwei Yang)
2236 • --with-valgrind=auto enables Valgrind instrumentation if and only if
2237 valgrind headers are available. The default is still --with-valgrind=no.
2238 (fd.o #56925, Simon McVittie)
2242 • Platforms with no 64-bit integer type are no longer supported.
2243 (fd.o #65429, Simon McVittie)
2245 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
2247 • Full test coverage no longer requires dbus-glib, although the tests do not
2248 exercise the shared library (only a static copy) if dbus-glib is missing.
2249 (fd.o #68852, Simon McVittie)
2253 • D-Bus Specification 0.22
2254 · Document GetAdtAuditSessionData() and
2255 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
2256 · Fix example .service file (fd.o #66481, Chengwei Yang)
2257 · Don't claim D-Bus is "low-latency" (lower than what?), just
2258 give factual statements about it supporting async use
2259 (fd.o #65141, Justin Lee)
2260 · Document the contents of .service files, and the fact that
2261 system services' filenames are constrained
2262 (fd.o #66608; Simon McVittie, Chengwei Yang)
2264 • Be thread-safe by default on all platforms, even if
2265 dbus_threads_init_default() has not been called. For compatibility with
2266 older libdbus, library users should continue to call
2267 dbus_threads_init_default(): it is harmless to do so.
2268 (fd.o #54972, Simon McVittie)
2270 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
2272 • New API: dbus_setenv(), a simple wrapper around setenv().
2273 Note that this is not thread-safe. (fd.o #39196, Simon)
2275 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
2276 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
2277 (connect to a given bus, like dbus-monitor --address=ADDRESS).
2278 dbus-send --address still exists for backwards compatibility,

2495 or the upcoming GNOME 3.8 release.
2497 Build-time configuration changes:
2499 • The --with-dbus-session-bus-default-address configure option is no longer
2500 supported. Use the new --with-dbus-session-bus-connect-address and
2501 --with-dbus-session-bus-listen-address options instead. On Windows, you
2502 usually want them to have the same argument; on Unix, the defaults are
2505 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2506 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2507 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2509 • cmake/cross-compile.sh has been removed. Instead, please use a
2510 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2511 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2512 as documented in "info automake Cross-Compilation", and set
2513 PKG_CONFIG_PATH appropriately.

2524 implements o.fd.DBus (fd.o #51865, Colin Walters)
2525 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
2526 · stop claiming that all basic types work just like INT32 (strings don't!)

2529 the outdated duplicate copies used when building with CMake.
2530 (fd.o #59805; Ralf Habacker, Simon McVittie)
2534 • In the activation helper, when compiled for tests, do not reset the system
2535 bus address, fixing the regression tests. (fd.o #52202, Simon)

2562 · The default session bus listening and connecting address is now
2563 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2564 and GDBus "out of the box". Use the configure options and cmake variables
2565 described above if you require a different autolaunch scope.

2704 (fd.o #39549, Simon McVittie)
2706 • Turn DBusBasicValue into public API so bindings don't need to invent their
2707 own "union of everything" type (fd.o #11191, Simon McVittie)

2718 · fix duplicate case value when compiling against mingw-w64
2719 (fd.o #47321, Andoni Morales Alastruey)
2721 D-Bus 1.5.10 (2012-02-21)
2724 The "fire in Delerium" release.
2726 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2727 and SUSv2) is now required.
2729 • D-Bus Specification 0.19:
2730 · Formally define unique connection names and well-known bus names,
2731 and document best practices for interface, bus, member and error names,
2732 and object paths (fd.o #37095, Simon McVittie)
2733 · Document the search path for session and system services on Unix, and
2734 where they should be installed by build systems (fd.o #21620, fd.o #35306;
2736 · Document the systemd transport (fd.o #35232, Lennart Poettering)
2738 • Make dbus_threads_init() use the same built-in threading implementation

2748 · only create batch files on Windows
2749 · fix option and cache syntax
2750 · add help-options target
2751 · share dbus-arch-deps.h.in with autotools rather than having our
2752 own version (fd.o #41033)
2754 • Build tests successfully with older GLib, as found in e.g. Debian 6
2755 (fd.o #41219, Simon McVittie)
2757 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
2759 • Build documentation correctly if man2html doesn't support filenames on
2760 its command-line (fd.o #43875, Jack Nagel)
2762 • Improve test coverage. To get even more coverage, run the tests with
2763 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
2765 • Reduce the size of the shared library by moving functionality only used
2766 by dbus-daemon, tests etc. into their internal library and deleting
2767 unused code (fd.o #34976, #39759; Simon McVittie)
2769 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2770 setups where the default configuration must include <pidfile/> to avoid
2771 breaking traditional init, but the pid file is in fact unnecessary; use
2772 it under systemd to improve startup time a bit (fd.o #45520,
2775 • Optionally (if configured --with-valgrind) add instrumentation to debug
2776 libdbus and associated tools more meaningfully under Valgrind
2777 (fd.o #37286, Simon McVittie)

2783 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
2784 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
2785 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
2788 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
2792 · Replace our broken reimplementation of recursive mutexes, which has
2793 been broken since 2006, with an ordinary pthreads recursive mutex
2794 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2795 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2796 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2797 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2798 · When running under systemd, use it instead of ConsoleKit to check
2799 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2800 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2801 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2802 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2803 (fd.o #41218, Simon McVittie)
2804 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2805 helper doesn't obey environment variables to avoid privilege escalation
2806 attacks, so make the system bus follow the same rules
2807 (fd.o #21620, Simon McVittie)
2810 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2811 Jesper Dam, Ralf Habacker)
2812 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
2815 D-Bus 1.5.8 (2011-09-21)
2818 The "cross-metering" release.
2820 In addition to dead code removal and refactoring, this release contains all
2821 of the bugfixes from 1.4.16.
2823 • Clean up dead code, and make more warnings fatal in development builds
2824 (fd.o #39231, fd.o #41012; Simon McVittie)
2826 • If full test coverage is requested via --enable-tests, strictly require
2827 Python, pygobject and dbus-python, which are required by some tests; if not,
2828 and Python is missing, skip those tests rather than failing
2829 (fd.o #37847, Simon McVittie)
2831 • When using cmake, provide the same version-info API in the installed headers
2832 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2834 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
2836 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
2838 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
2841 • Fix duplicates in authors list (Ralf Habacker)
2843 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2844 (fd.o #39879, Chris Mayo)
2846 • Fix a small memory leak, and a failure to report errors, when updating
2847 a service file entry for activation (fd.o #39230, Simon McVittie)
2850 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2851 Brian Cameron, Simon McVittie)
2852 · On systems that use libcap-ng but not systemd, drop supplemental groups
2853 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2854 · Make the cmake build work again on GNU platforms (fd.o #29228,
2856 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
2857 like Solaris (fd.o #40313, Dagobert Michelsen)
2858 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2859 (fd.o #40235, Simon McVittie)
2860 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2861 (fd.o #39987, Simon McVittie)
2862 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2863 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2866 · Fix compilation on MSVC, which doesn't understand "inline" with its
2867 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2868 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2869 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2871 D-Bus 1.5.6 (2011-07-29)
2874 The "weird, gravy-like aftertaste" release.
2876 In addition to new features and refactoring, this release contains all of the
2877 bugfixes from 1.4.14.
2879 Potentially incompatible (Bustle and similar debugging tools will need
2880 changes to work as intended):
2882 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2883 different recipient) by mistake: eavesdroppers must now opt-in to this
2884 behaviour by putting "eavesdrop='true'" in the match rule, which will
2885 not have any practical effect on buses where eavesdropping is not allowed
2886 (fd.o #37890, Cosimo Alfarano)
2890 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2891 Cosimo Alfarano, Simon McVittie)
2892 · add the "eavesdrop" keyword to match rules
2893 · define eavesdropping, unicast messages and broadcast messages
2894 · stop claiming that match rules are needed to match unicast messages to you
2895 · promote the type system to be a top-level section
2897 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2898 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2899 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2901 • Consistently use atomic operations on everything that is ever manipulated
2902 via atomic ops, as was done for changes to DBusConnection's refcount in
2903 1.4.12 (fd.o #38005, Simon McVittie)
2905 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2908 • Make "make check" in a clean tree work, by not running tests until
2909 test data has been set up (fd.o #34405, Simon McVittie)
2911 • The dbus-daemon no longer busy-loops if it has a very large number of file
2912 descriptors (fd.o #23194, Simon McVittie)
2914 • Refactor message flow through dispatching to avoid locking violations if
2915 the bus daemon's message limit is hit; remove the per-connection link cache,
2916 which was meant to improve performance, but now reduces it (fd.o #34393,
2919 • Some cmake fixes (Ralf Habacker)
2921 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2922 Simon McVittie, Lennart Poettering)
2924 • Stop storing two extra byte order indicators in each D-Bus message
2925 (fd.o #38287, Simon McVittie)
2927 • Add an optional Stats interface which can be used to get statistics from
2928 a running dbus-daemon if enabled at configure time with --enable-stats
2929 (fd.o #34040, Simon McVittie)
2931 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2933 • Documentation (fd.o #36156, Simon McVittie):
2934 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2935 · install more documentation automatically, including man2html output
2936 · put dbus.devhelp in the right place (it must go in ${htmldir})
2939 · look for system services in /lib/dbus-1/system-services in addition to all
2940 the other well-known locations; note that this should always be /lib,
2941 even on platforms where shared libraries on the root FS would go in /lib64,
2942 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2943 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2945 • Windows-specific (Ralf Habacker):
2946 · fix use of a mutex for autolaunch server detection
2947 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2949 D-Bus 1.5.4 (2011-06-10)
2952 Security (local denial of service):
2954 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2955 local DoS if foreign-endian messages are relayed through the dbus-daemon
2956 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2957 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2961 • The constant to use for an infinite timeout now has a name,
2962 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2963 which can be used for source compatibility with older versions of libdbus.
2965 • If GLib and DBus-GLib are already installed, more tests will be built,
2966 providing better coverage. The new tests can also be installed via
2967 ./configure --enable-installed-tests
2968 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2972 • Consistently use atomic operations for the DBusConnection's refcount,
2973 fixing potential threading problems (fd.o #38005, Simon McVittie)
2975 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2976 small (300KiB on x86-64) and it frequently doesn't work in unusual
2977 toolchains. To optimize for minimum installed size, you should benchmark
2978 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2979 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2981 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2982 (fd.o #35880, Timothy Redaelli)
2984 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2985 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2987 • Windows-specific changes:
2988 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2990 D-Bus 1.5.2 (2011-06-01)
2993 The "Boar Hunter" release.
2995 Notes for distributors:
2997 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2998 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2999 toolchain supports it reliably, via something like:
3001 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
3003 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
3007 • D-Bus Specification v0.17
3008 · Reserve the extra characters used in signatures by GVariant
3009 (fd.o #34529, Simon McVittie)
3010 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
3011 • Don't force -fPIE: distributions and libtool know better than we do whether
3012 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
3013 • Allow --disable-gc-sections, in case your toolchain offers the
3014 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
3015 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
3016 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
3017 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
3018 • Ensure that maintainers upload documentation with the right permissions
3019 (fd.o #36130, Simon McVittie)
3020 • Don't force users of libdbus to be linked against -lpthread, -lrt
3021 (fd.o #32827, Simon McVittie)
3022 • Log system-bus activation information to syslog (fd.o #35705,
3024 • Log messages dropped due to quotas to syslog (fd.o #35358,
3026 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
3027 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
3028 (fd.o #35228, Lennart Poettering)
3029 • In the regression tests, don't report fds as "leaked" if they were open
3030 on startup (fd.o #35173, Simon McVittie)
3031 • Make dbus-monitor bail out if asked to monitor more than one bus,
3032 rather than silently using the last one (fd.o #26548, Will Thompson)
3033 • Clarify documentation (fd.o #35182, Simon McVittie)
3034 • Clean up minor dead code and some incorrect error handling
3035 (fd.o #33128, fd.o #29881; Simon McVittie)
3036 • Check that compiler options are supported before using them (fd.o #19681,
3039 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
3041 D-Bus 1.5.0 (2011-04-11)
3044 The "you never know when you need to tow something from your giant
3045 flying shark" release.
3047 • D-Bus Specification v0.16
3048 · Add support for path_namespace and arg0namespace in match rules
3049 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
3050 · Make argNpath support object paths, not just object-path-like strings,
3051 and document it better (fd.o #31818, Will Thompson)
3052 • Let the bus daemon implement more than one interface (fd.o #33757,
3054 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
3056 • Require user intervention to compile with missing 64-bit support
3057 (fd.o #35114, Simon McVittie)
3058 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
3059 • Raise UnknownObject instead of UnknownMethod for calls to methods on
3060 paths that are not part of the object tree, and UnknownInterface for calls
3061 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
3063 D-Bus 1.4.8 (2011-04-08)
3066 The "It's like the beginning of a lobster" release.
3068 • Rename configure.in to configure.ac, and update it to modern conventions
3069 (fd.o #32245; Javier Jardón, Simon McVittie)
3070 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
3072 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
3073 --disable-x11-autolaunch configure option to prevent it altogether
3074 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
3075 • Install the documentation, and an index for Devhelp (fd.o #13495,
3076 Debian #454142; Simon McVittie, Matthias Clasen)
3077 • If checks are not disabled, check validity of string-like types and
3078 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
3079 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
3080 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
3081 • Break up a huge conditional in config-parser so gcov can produce coverage
3082 data (fd.o #10887, Simon McVittie)
3083 • List which parts of the Desktop Entry specification are applicable to
3084 .service files (fd.o #19159, Sven Herzberg)
3085 • Don't suppress service activation if two services have the same Exec=
3086 (fd.o #35750, Colin Walters)

3096 The "1, 2, miss a few, 99, 100" release.
3098 • Remove unfinished changes intended to support GTest-based tests,
3099 which were mistakenly included in 1.4.4
3101 D-Bus 1.4.4 (2010-02-17)
3104 • Switch back to using even micro versions for stable releases; 1.4.1
3105 should have been called 1.4.2, so skip that version number
3106 • Don't leave bad file descriptors being watched when spawning processes,
3107 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
3108 also LP#656134, LP#680444, LP#713157)
3109 • Check for MSG_NOSIGNAL correctly
3110 • Fix failure to detect abstract socket support (fd.o #29895)
3111 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
3112 (fd.o #32262, NB#180486)

3139 D-Bus 1.4.1 (20 December 2010)
3142 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
3143 crash the bus. The existing restriction to 64-levels of nesting previously
3144 only applied to the static type signature; now it also applies to dynamic
3145 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
3147 • OS X portability fixes, including launchd support.
3148 • Windows autolaunch improvements.
3149 • Various bug fixes.
