1 dbus 1.12.22 (UNRELEASED)
2 =========================
6 • Avoid malloc() after fork on non-GNU libc (dbus!181, Jean-Louis Fuchs)
8 • Fix build with clang 13 by using Standard C offsetof where available
9 (dbus!237, Simon McVittie)
11 • Fix build of tests on FreeBSD (dbus!167, Simon McVittie)
13 • Make documentation build more reproducible
14 (dbus!189, dbus!238; Arnout Engelen, Simon McVittie)
16 • On Unix, make X11 autolaunch cope with slashes in DISPLAY
17 (dbus#8, dbus#311; William Earley)
19 • Don't try to raise RLIMIT_NOFILE beyond OPEN_MAX on macOS
20 (dbus#309, William Earley)
22 dbus 1.12.20 (2020-07-02)
23 =========================
25 The “temporary nemesis” release.
29 • On Unix, avoid a use-after-free if two usernames have the same
30 numeric uid. In older versions this could lead to a crash (denial of
31 service) or other undefined behaviour, possibly including incorrect
32 authorization decisions if <policy group=...> is used.
33 Like Unix filesystems, D-Bus' model of identity cannot distinguish
34 between users of different names with the same numeric uid, so this
35 configuration is not advisable on systems where D-Bus will be used.
36 Thanks to Daniel Onaca.
37 (dbus#305, dbus!166, CVE-2020-35512; Simon McVittie)
41 • On Solaris and its derivatives, if a cmsg header is truncated, ensure
42 that we do not overrun the buffer used for fd-passing, even if the
44 (dbus#304, dbus!165; Andy Fiddaman)
46 dbus 1.12.18 (2020-06-02)
47 =========================
49 The “telepathic vines” release.
51 Denial of service fixes:
53 • CVE-2020-12049: If a message contains more file descriptors than can
54 be sent, close those that did get through before reporting error.
55 Previously, a local attacker could cause the system dbus-daemon (or
56 another system service with its own DBusServer) to run out of file
57 descriptors, by repeatedly connecting to the server and sending fds that
59 Thanks to Kevin Backhouse of GitHub Security Lab.
60 (dbus#294, GHSL-2020-057; Simon McVittie)
64 • Fix a crash when the dbus-daemon is terminated while one or more
65 monitors are active (dbus#291, dbus!140; Simon McVittie)
67 • The dbus-send(1) man page now documents --bus and --peer instead of
68 the old --address synonym for --peer, which has been deprecated since
69 the introduction of --bus and --peer in 1.7.6
70 (fd.o #48816, dbus!115; Chris Morin)
72 • Fix a wrong environment variable name in dbus-daemon(1)
73 (dbus#275, dbus!122; Mubin, Philip Withnall)
75 • Fix formatting of dbus_message_append_args example
76 (dbus!126, Felipe Franciosi)
78 • Avoid a test failure on Linux when built in a container as uid 0, but
79 without the necessary privileges to increase resource limits
80 (dbus!58, Debian #908092; Simon McVittie)
82 • When building with CMake, cope with libX11 in a non-standard location
83 (dbus!129, Tuomo Rinne)
85 dbus 1.12.16 (2019-06-11)
86 =========================
88 The “tree cat” release.
92 • CVE-2019-12749: Do not attempt to carry out DBUS_COOKIE_SHA1
93 authentication for identities that differ from the user running the
94 DBusServer. Previously, a local attacker could manipulate symbolic
95 links in their own home directory to bypass authentication and connect
96 to a DBusServer with elevated privileges. The standard system and
97 session dbus-daemons in their default configuration were immune to this
98 attack because they did not allow DBUS_COOKIE_SHA1, but third-party
99 users of DBusServer such as Upstart could be vulnerable.
100 Thanks to Joe Vennix of Apple Information Security.
101 (dbus#269, Simon McVittie)
103 dbus 1.12.14 (2019-05-17)
104 =========================
106 The “reclaimed floorboards” release.
110 • Raise soft fd limit to match hard limit, even if unprivileged.
111 This makes session buses with many clients, or with clients that make
112 heavy use of fd-passing, less likely to suffer from fd exhaustion.
113 (dbus!103, Simon McVittie)
117 • If a privileged dbus-daemon has a hard fd limit greater than 64K, don't
118 reduce it to 64K, ensuring that we can put back the original fd limits
119 when carrying out traditional (non-systemd) activation. This fixes a
120 regression with systemd >= 240 in which system services inherited
121 dbus-daemon's hard and soft limit of 64K fds, instead of the intended
122 soft limit of 1K and hard limit of 512K or 1M.
123 (dbus!103, Debian#928877; Simon McVittie)
125 • Fix build failures caused by an AX_CODE_COVERAGE API change in newer
126 autoconf-archive versions (dbus#249, dbus!88; Simon McVittie)
128 • Fix build failures with newer autoconf-archive versions that include
129 AX_-prefixed shell variable names (dbus#249, dbus!86; Simon McVittie)
131 • Parse section/group names in .service files according to the syntax
132 from the Desktop Entry Specification, rejecting control characters
133 and non-ASCII in section/group names (dbus#208, David King)
135 • Fix various -Wlogical-op issues that cause build failure with newer
136 gcc versions (dbus#225, dbus!109; David King)
138 • Don't assume we can set permissions on a directory, for the benefit of
139 MSYS and Cygwin builds (dbus#216, dbus!110; Simon McVittie)
141 • Don't overwrite PKG_CONFIG_PATH and related environment variables when
142 the pkg-config-based version of DBus1Config is used in a CMake project
143 (dbus#267, dbus!96; Clemens Lang)
145 dbus 1.12.12 (2018-12-04)
146 =========================
148 The “draconic disciple” release.
150 dbus version control is now hosted on freedesktop.org's Gitlab
151 installation, and bug reports and feature requests have switched from
152 Bugzilla bugs (indicated by "fd.o #nnn") to Gitlab issues ("dbus#nnn")
153 and merge requests ("dbus!nnn").
157 • Reference the freedesktop.org Code of Conduct (Simon McVittie)
161 • Stop the dbus-daemon leaking memory (an error message) if delivering
162 the message that triggered auto-activation is forbidden. This is
163 technically a denial of service because the dbus-daemon will
164 run out of memory eventually, but it's a very slow and noisy one,
165 because all the rejected messages are also very likely to have
166 been logged to the system log, and its scope is typically limited by
167 the finite number of activatable services available.
168 (dbus#234, Simon McVittie)
170 • Remove __attribute__((__malloc__)) attribute on dbus_realloc(),
171 which does not meet the criteria for that attribute in gcc 4.7+,
172 potentially leading to miscompilation (fd.o #107741, Simon McVittie)
174 • Fix some small O(1) memory leaks (fd.o #107320, Simon McVittie)
176 • Fix printf formats for pointer-sized integers on 64-bit Windows
177 (fd.o #105662, Ralf Habacker)
179 • Always use select()-based poll() emulation on Darwin-based OSs
180 (macOS, etc.) and on Interix, similar to what libcurl does
181 (dbus#232, dbus!19; Simon McVittie)
183 • Extend a test timeout to avoid spurious failures in CI
184 (dbus!26, Simon McVittie)
188 • Add Travis-CI builds for 64-bit Windows using mingw-w64
189 (fd.o #105662, Ralf Habacker)
191 • Add Gitlab-CI integration (fd.o #108177, Simon McVittie)
193 dbus 1.12.10 (2018-08-02)
194 =========================
196 The “beam deflection” release.
200 • Prevent reading up to 3 bytes beyond the end of a truncated message.
201 This could in principle be an information leak or denial of service
202 on the system bus, but is not believed to be exploitable to crash
203 the system bus or leak interesting information in practice.
204 (fd.o #107332, Simon McVittie)
206 • Fix build with gcc 8 -Werror=cast-function-type
207 (fd.o #107349, Simon McVittie)
209 • Fix warning from gcc 8 about suspicious use of strncpy() when
210 populating struct sockaddr_un (fd.o #107350, Simon McVittie)
212 • Fix a minor memory leak when a DBusServer listens on a new address
213 (fd.o #107194, Simon McVittie)
215 • Fix an invalid NULL argument to rmdir() if a nonce-tcp DBusServer
216 runs out of memory (fd.o #107194, Simon McVittie)
218 • Don't use misleading errno-derived error names if getaddrinfo() or
219 getnameinfo() fails with a code other than EAI_SYSTEM
220 (fd.o #106395, Simon McVittie)
222 • Skip tests that require working TCP if we are in a container environment
223 where 127.0.0.1 cannot be resolved (fd.o #106812, Simon McVittie)
225 dbus 1.12.8 (2018-04-30)
226 ========================
228 The “golden super-velociraptor” release.
232 • The Devhelp documentation index is now in version 2 format
233 (fd.o #106186, Simon McVittie)
235 • Give the dbus-daemon man page some scarier warnings about
236 <allow_anonymous/> and non-local TCP, which are insecure and should
237 not be used, particularly for the standard system and session buses
238 (fd.o #106004, Simon McVittie)
242 • Fix installation of Ducktype documentation with newer yelp-build
243 versions (fd.o #106171, Simon McVittie)
245 dbus 1.12.6 (2018-03-01)
246 ========================
248 The “just the one swan, actually” release.
252 • Increase system dbus-daemon's RLIMIT_NOFILE rlimit before it drops
253 privileges, because it won't have permission afterwards. This fixes a
254 regression in dbus 1.10.18 and 1.11.0 which made the standard system bus
255 more susceptible to deliberate or accidental denial of service.
256 (fd.o #105165, David King)
258 dbus 1.12.4 (2018-02-08)
259 ========================
261 The “Stria Campania 115” release.
265 • When iterating the DBusConnection while blocking on a pending call,
266 don't wait for I/O if that pending call already has a result; and make
267 sure that whether it has a result is propagated in a thread-safe way.
268 This prevents certain multi-threaded calling patterns from blocking
269 until their timeout even when they should have succeeded sooner.
270 (fd.o #102839; Manish Narang, Michael Searle)
272 • Report the correct error if OOM is reached while trying to listen
273 on a TCP socket (fd.o #89104, Simon McVittie)
275 • Fix assertion failures in recovery from OOM while setting up a
276 DBusServer (fd.o #89104, Simon McVittie)
278 • Add a missing space to a warning message (fd.o #103729, Thomas Zajic)
280 • Expand ${bindir} correctly when pkg-config is asked for dbus_daemondir
281 (fd.o #104265, Benedikt Heine)
283 • On Linux systems with systemd < 237, if ${localstatedir}/dbus doesn't
284 exist, create it before trying to create ${localstatedir}/dbus/machine-id
285 (fd.o #104577, Chris Lesiak)
287 • Fix escaping in dbus-api-design document (fd.o #104925, Philip Withnall)
289 dbus 1.12.2 (2017-11-13)
290 ========================
292 The “spider pumpkin” release.
296 • Log a warning if a new connection cannot be accepted due to an
297 out-of-memory condition or failure to identify its AppArmor or
298 SELinux context (fd.o #103592, Simon McVittie)
302 • Make use of $(MKDIR_P) compatible with install-sh, fixing build when a
303 GNU-compatible `mkdir -p` is not available (fd.o #103521, ilovezfs)
305 • When building for Windows with Autotools, avoid `echo -e`, fixing
306 cross-compilation on non-GNU platforms like macOS
307 (fd.o #103493, Tony Theodore)
309 • Fix crashes in the server side of the nonce-tcp: transport under
310 various error conditions. This transport should normally only be used
311 on Windows, where AF_UNIX sockets are unavailable; the unix: transport
312 is the only one recommended for production use on Unix platforms.
313 (fd.o #103597, Simon McVittie)
317 • Improve test coverage on Travis-CI (Simon McVittie)
319 dbus 1.12.0 (2017-10-30)
320 ========================
322 The “gingerbread skull” release.
324 1.12.x is a new stable branch, recommended for use in OS
327 Summary of major changes between 1.10.x and 1.12.0
328 --------------------------------------------------
332 • Expat >= 2.1.0 is required.
333 • GLib >= 2.40 is required if full test coverage is enabled.
334 • [Linux] libselinux >= 2.0.86 is required if SELinux support is
336 • [Unix] dbus now requires an <inttypes.h> that defines C99 constants
337 such as PRId64 and PRIu64, except when building for Windows.
338 • [Autotools] Building from git (but not from tarballs) with Autotools
339 now requires macros from the GNU Autoconf Archive.
340 • [CMake] Builds done using CMake now require CMake 3.0.2.
342 Build-time configuration changes:
344 • Expat is now found using pkg-config. See the release notes for
346 • The --disable-compiler-optimisations and --enable-compiler-coverage
347 options no longer exist. See the release notes for 1.11.4 and 1.11.8.
348 • [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
349 options no longer exist. See the release notes for 1.11.20.
350 • [Unix] Flag files in /var/run/console/${username} are no longer
351 checked for at_console by default. See the release notes for 1.11.18.
352 • [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
353 and packagers will now need to add these downstream (most already do).
354 See the release notes for 1.11.18.
355 • [Unix] The process ID file no longer has a different default location
356 on Red Hat derivatives. See the release notes for 1.11.18.
357 • [Unix] ${runstatedir} is now independent of ${localstatedir} with
358 recent Autotools versions. See the release notes for 1.11.16.
359 • [Windows] The WINDRES variable is no longer used. See the release
364 • Eavesdropping is officially deprecated in favour of BecomeMonitor.
365 See the release notes for spec version 0.31 (in dbus 1.11.14).
366 • [Unix] Flag files in /var/run/console/${username} are deprecated.
367 See the release notes for 1.11.18.
371 • <allow> and <deny> rules in dbus-daemon configuration can now
372 include send_broadcast="true", send_broadcast="false",
373 max_unix_fds="N", min_unix_fds="N" (for some integer N).
374 See the release notes for 1.11.18.
375 • dbus_try_get_local_machine_id() is like
376 dbus_get_local_machine_id(), but returns a DBusError.
377 • New APIs around DBusMessageIter to simplify cleanup.
378 See the release notes for 1.11.16.
379 • The message bus daemon now implements the standard Introspectable,
380 Peer and Properties interfaces. See the release notes for
381 dbus 1.11.14 and spec version 0.31.
382 • DTDs for introspection XML and bus configuration are installed.
383 • dbus can be compiled to be relocatable, making it more suitable for
384 binary bundling with other software. On Windows, this is on by
386 • [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
387 never uses Linux abstract sockets, which is advantageous for
388 containers. On non-Linux it is equivalent to unix:tmpdir=….
389 See the release notes for dbus 1.11.14 and spec version 0.31.
390 • [Unix] New option "dbus-launch --exit-with-x11".
391 • [Unix] Session managers can create transient .service files in
392 $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
393 • [Unix] A sysusers.d snippet can create the messagebus user on-demand.
395 Miscellaneous behaviour changes:
397 • [Unix] The session bus now logs to syslog if it was started by
399 • [Unix] Internal warnings are logged to syslog if configured.
400 • [Unix] Exceeding an anti-DoS limit is logged to syslog if configured,
403 Changes since 1.11.22 release candidate
404 ---------------------------------------
406 Standard stable-branch changes:
408 • Disable warnings about use of deprecated functions (Simon McVittie)
412 • Don't distribute files generated by ./configure in the source tarball
413 (fd.o #103420, Simon McVittie)
417 • Remove some unused files from the git repository
418 (fd.o #103420, Simon McVittie)
420 D-Bus 1.11.22 (2017-10-23)
421 ==========================
423 The “fire surface” release.
425 This is the first release-candidate for the 1.12.0 stable release.
427 Build-time configuration changes:
429 • When building for Windows with Autotools, setting the WINDRES variable
430 no longer works to select a non-standard resource compiler. Use
431 libtool's standard RC variable instead, for example
432 "./configure RC=i686-w64-mingw32-windres"
436 • Builds done using CMake now require CMake 3.0.2.
440 • When building for Windows, improve quality of metadata in
441 libdbus-1-3.dll (fd.o #103015, Ralf Habacker)
445 • Fix a typo "uint 16" in dbus-send(1) man page
446 (fd.o #103075, David King)
448 • When building for Windows, libdbus-1-3.dll always includes version
449 information. Previously, this was missing if using CMake and any
450 non-MSVC compiler. (fd.o #103015, Ralf Habacker)
452 • Fix the build with MSVC, which regressed with the #102558 fix in
453 1.11.20. (fd.o #102558, Ralf Habacker)
457 • Simplify Windows resource embedding
458 (fd.o #103015, Simon McVittie)
460 D-Bus 1.11.20 (2017-10-03)
463 The “wraith stun” release.
465 Build-time configuration changes:
467 • The --enable-abstract-sockets and --disable-abstract-sockets options
468 no longer exist. Support for Linux's abstract AF_UNIX sockets is now
469 unconditionally enabled on Linux and disabled everywhere else.
470 (fd.o #34905, Simon McVittie)
474 • Make slower tests less likely to time out, and improve diagnostics if
475 tests do time out (fd.o #103009, Simon McVittie)
477 • On Windows, don't compile an unused stub implementation of
478 _dbus_set_signal_handler() (fd.o #103010, Simon McVittie)
482 • Be more careful to save and restore errno in POSIX async signal
483 handlers (fd.o #103010, Simon McVittie)
485 • On Windows, embed a manifest in dbus-update-activation-environment.exe
486 so that the heuristics used for UAC do not assume it needs elevated
487 privileges due to its name containing "update"
488 (fd.o #102558, Ralf Habacker)
490 • On Windows with Automake, embed version information in libdbus-1,
491 as was meant to happen in all versions since 2009
492 (fd.o #103015, Simon McVittie)
494 D-Bus 1.11.18 (2017-09-25)
497 The “vampire conquistador” release.
499 Build-time configuration changes:
501 • By default, dbus-daemon on Unix no longer checks for flag files
502 /var/run/console/${username} created by the obsolete pam_console and
503 pam_foreground PAM modules when deciding whether ${username} is
504 currently at the console. The old default behaviour can be restored
505 by specifying --with-console-auth-dir=/var/run/console in the
506 recommended Autotools build system, or
507 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
508 now deprecated, and will be removed in dbus 1.13 unless feedback via
509 fd.o #101629 indicates that this would be problematic.
510 (fd.o #101629, Simon McVittie)
512 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
513 script for Cygwin, are no longer provided in the upstream dbus
514 source. We recommend that distributors who support non-systemd service
515 management should maintain their own init scripts or other service
516 manager integration as part of their downstream packaging, similar to
517 the way Debian distributes a Debian-specific LSB init script for dbus.
519 The systemd unit continues to be maintained as part of the upstream
520 dbus source, because it receives regular testing and maintenance.
522 (fd.o #101706, Simon McVittie)
524 • The process ID file created by the system bus is no longer influenced
525 by the --with-init-scripts=redhat configure option or the presence of
526 /etc/redhat-release at build time. If your OS's init script or other
527 service management relies on the Red Hat-style pid file, it can be
528 restored by specifying --with-system-pid-file=/run/messagebus.pid at
529 configure time or using the <pidfile> directive in bus configuration.
531 Note that the upstream-supplied systemd unit runs dbus-daemon with
532 the --nopidfile option, so it does not normally write a pid file,
533 regardless of whether the OS is Red-Hat-derived or not.
535 (fd.o #101706, Simon McVittie)
539 • <allow> and <deny> rules in dbus-daemon configuration can now
540 include send_broadcast="true" or send_broadcast="false", which make
541 the rule only match broadcast signals, or only match messages that
542 are not broadcast signals, respectively.
543 (fd.o #29853, Simon McVittie)
545 • <allow> and <deny> rules can now be configured to apply only to
546 messages with or without Unix file descriptors attached. This would
547 typically be used in rules like these:
548 <allow send_destination="..." max_unix_fds="0"/>
549 <deny send_destination="..." min_unix_fds="1"/>
550 <deny receive_sender="..." min_unix_fds="1"/>
551 but can also be used to set a nonzero upper limit on the number of
553 <allow send_destination="..." max_unix_fds="4"/>
554 (fd.o #101848, Simon McVittie)
556 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
557 now respects the HOME environment variable on the client side, and
558 on the server side when the uid attempting to connect is the same
559 as the uid of the server. This allows the automated tests to pass in
560 environments where the user's "official" home directory in /etc/passwd
561 is nonexistent, such as Debian autobuilders.
562 (fd.o #101960, Simon McVittie)
566 • When parsing dbus-daemon configuration, tell Expat not to use
567 cryptographic-quality entropy as a salt for its hash tables: we trust
568 the configuration files, so we are not concerned about algorithmic
569 complexity attacks via hash table collisions. This prevents
570 dbus-daemon --system from holding up the boot process (and causing
571 early-boot system services like systemd, logind, networkd to time
572 out) on entropy-starved embedded systems.
573 (fd.o #101858, Simon McVittie)
575 • Avoid a -Werror=declaration-after-statement build failure on Solaris
576 (fd.o #102145, Alan Coopersmith)
578 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
579 to LOG_INFO, matching how we use this log level in practice
580 (fd.o #102686, Simon McVittie)
582 D-Bus 1.11.16 (2017-07-27)
585 The “south facing garden” release.
587 Build-time configuration changes:
589 • The Autotools build system now supports varying ${runstatedir}
590 independently of ${localstatedir}, if using an Autoconf version
591 that has that feature; version 2.70 will eventually have this, but
592 many Linux distributions add it to version 2.69 as a patch.
593 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
594 and runstatedir=/run. (fd.o #101569, Simon McVittie)
598 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
599 and dbus_message_iter_abandon_container_if_open() simplify the
600 single-exit-point ("goto out") style of resource cleanup. The API
601 documentation around DBusMessageIter and containers has also been
602 clarified. (fd.o #101568, Simon McVittie)
606 • Fix the implementation of re-enabling a timeout (again) so that its
607 countdown is always restarted as intended. (fd.o #95619,
610 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
611 available to all users on the system bus (fd.o #101700, Simon McVittie)
613 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
614 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
616 • dbus_message_iter_open_container() no longer leaks memory if it runs out
617 of memory. (fd.o #101568, Simon McVittie)
619 • dbus_message_append_args_valist() no longer leaks memory if given an
620 unsupported type. This situation is still considered to be a programming
621 error which needs to be corrected by the user of libdbus.
622 (fd.o #101568, Simon McVittie)
624 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
625 will no longer report that their arguments were invalid if they run out
626 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
628 • Ensure that tests fail if they would otherwise have tried to connect to
629 the real session bus (fd.o #101698, Simon McVittie)
631 • Make build-time tests cope with finding Python 3, but not Python 2
632 (fd.o #101716, Simon McVittie)
634 Internal changes relevant to dbus developers:
636 • DBusVariant is a new mechanism to copy single values from a message into
637 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
639 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
640 Logging an ERROR message does not make the process exit; the caller
641 is responsible for calling abort() or exit(), whichever is more appropriate.
642 (fd.o #101568, Simon McVittie)
644 • Better test coverage (fd.o #101568, Simon McVittie)
646 D-Bus 1.11.14 (2017-06-29)
649 The “irrational fear of bees” release.
653 • Expat >= 2.1.0 is always required
654 • libselinux >= 2.0.86 is required if SELinux support is enabled
655 • GLib >= 2.40 is required if full test coverage is enabled
657 Build-time configuration changes:
659 • We now use pkg-config to find libexpat in Autotools builds. This requires
660 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
661 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
662 itself cause compilation failures.
664 As with all pkg-config-based configure checks, you can use
665 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
666 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
667 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
670 (fd.o #69801, Simon McVittie)
672 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
673 is required due to the removal of explicit refcounting for SIDs.
674 (fd.o #100912, Laurent Bigonville)
678 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
679 as a side-effect of a sufficiently privileged process merely reading the
680 machine ID. It is no longer copied as a side-effect of reading.
681 Running dbus-uuidgen --ensure, which should be done after installing dbus,
682 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
683 former exists and the latter does not.
684 (fd.o #101257, Simon McVittie)
686 • The undocumented Verbose interface, and the GetAllMatchRules method on
687 the undocumented Stats interface, must now be used via the object path
688 /org/freedesktop/DBus. Previously, they existed on all object paths.
689 (fd.o #101257, Simon McVittie)
691 • AddMatch() with a match rule containing eavesdrop='true' will now fail
692 unless called by either the same user as the dbus-daemon, or Unix uid 0
693 (root), matching the restrictions applied to the newer BecomeMonitor()
694 method. On the session bus this has no practical effect. On the system
695 bus this will prevent certain configurations that already did not
696 work well in practice. (fd.o #101567, Simon McVittie)
700 • D-Bus Specification version 0.31
701 · Don't require implementation-specific search paths to be lowest
703 · Correct regex syntax for optionally-escaped bytes in addresses so it
704 includes hyphen-minus, forward slash and underscore as intended
705 · Describe all message bus methods in the same section
706 · Clarify the correct object path for method calls to the message bus
707 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
708 · Document that the message bus implements Introspectable, Peer and
710 · Add new Features and Interfaces properties for message bus
712 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
714 · Don't require eavesdrop='true' to be accepted from connections not
715 sufficiently privileged to use it successfully
716 · Formally deprecate eavesdropping in favour of BecomeMonitor
717 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
718 Simon McVittie, Tom Gundersen)
720 • Implement the Properties and Peer interfaces in dbus-daemon
721 (fd.o #101257, Simon McVittie)
723 • New function dbus_try_get_local_machine_id() is like
724 dbus_get_local_machine_id(), but returning a DBusError. Other code
725 that needs the machine ID will now report a recoverable error (instead
726 of logging to stderr and aborting) if no machine ID is available.
727 Generating a machine ID is still considered to be a required part of
728 installing dbus correctly. (fd.o #13194, Simon McVittie)
730 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
731 (fd.o #101315, Laurent Bigonville)
733 • Avoid deprecated API calls when using SELinux
734 (fd.o #100912, Laurent Bigonville)
736 • Switch a test from the deprecated g_test_trap_fork() to
737 g_test_trap_subprocess(), for Windows support and better robustness
738 on Unix (fd.o #101362, Simon McVittie)
740 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
741 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
742 This prevents the two files from going out of sync on stateless or live
743 images without needing to run dbus-uuidgen, and supports older D-Bus
744 implementations that do not necessarily read /etc/machine-id themselves.
745 (fd.o #101570, Simon McVittie)
747 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
748 abstract sockets. This is preferable when used with Linux containers.
749 (fd.o #101567, Simon McVittie)
753 • Fix a reference leak when blocking on a pending call on a connection
754 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
756 • Don't put timestamps in the Doxygen-generated documentation,
757 or hard-code the build directory into builds with embedded tests,
758 for reproducible builds (fd.o #100692, Simon McVittie)
760 • Fix some integration test issues (fd.o #100686, Simon McVittie)
762 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
764 • If we somehow get an autolaunch address with multiple semicolon-separated
765 components, and they don't work, don't invalidly "pile up" errors
766 (fd.o #101257, Simon McVittie)
770 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
771 (fd.o #100715, Simon McVittie)
773 D-Bus 1.11.12 (2017-04-07)
776 The “it's something humans do” release.
780 • The session dbus-daemon now supports transient .service files
781 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
782 service directories, this directory is not monitored with inotify
783 or similar, and the service files must be named exactly
784 ${bus_name}.service. (fd.o #99825, Simon McVittie)
786 • dbus can be configured with --enable-relocation when building with
787 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
788 to make the pkg-config metadata relocatable. This is useful for
789 non-standard prefixes, and in particular for Windows installations.
790 However, it is not recommended for system-wide installations into
791 /usr, because it interferes with pkg-config's ability to filter out
792 compiler default linker directories.
794 With Autotools, the default is --enable-relocation when building
795 for Windows or --disable-relocation otherwise. With CMake, the default
796 is -DDBUS_RELOCATABLE=ON.
798 (fd.o #99721; Ralf Habacker, Simon McVittie)
800 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
801 own FindDBus.cmake macros, whether dbus was compiled with Autotools
802 or with CMake. See the end of README.cmake for more information.
803 (fd.o #99721; Ralf Habacker, Simon McVittie)
807 • Always read service file directories in the intended order
808 (fd.o #99825, Simon McVittie)
810 • When tests are skipped, don't try to kill nonexistent process 0
811 (fd.o #99825, Simon McVittie)
813 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
815 • Fix a harmless read overflow and some memory leaks in a unit test
816 (fd.o #100568, Philip Withnall)
818 • Fix some typos in test code
819 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
821 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
822 in documentation (fd.o #99901, Philip Withnall)
824 • Fix and enable compiler warnings related to -Wswitch
825 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
827 • Fix writing off the end of a fd_set when testing with valgrind
828 (fd.o #99839, Philip Withnall)
830 D-Bus 1.11.10 (2017-02-16)
833 The “purple hair gives you telekinesis?” release.
837 • AppArmor support requires at least libapparmor 2.8.95, reduced
838 from 2.10 in previous versions. One test requires 2.10 and is
839 skipped if building with an older version.
843 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
844 stable and Debian testing in addition to the older Ubuntu that is
845 the default (fd.o #98889, Simon McVittie)
847 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
849 • Silence many -Wswitch-enum and -Wswitch-default warnings
850 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
852 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
853 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
855 • Install pkg-config metadata on Unix even if building with CMake
856 (fd.o #99752, Ralf Habacker)
858 • Exclude auth mechanisms from REJECTED message if they are supported
859 in the code but but configured to be disallowed (fd.o #99621,
864 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
865 allow an attacker to overwrite a file named "nonce", in a directory
866 that the user running dbus-daemon can write, with a random value
867 known only to the user running dbus-daemon. This is unlikely to be
868 exploitable in practice, particularly since the nonce-tcp transport
869 is really only useful on Windows.
871 On Unix systems we strongly recommend using only the unix: and systemd:
872 transports, together with EXTERNAL authentication. These are the only
873 transports and authentication mechanisms enabled by default.
875 (fd.o #99828, Simon McVittie)
877 • Avoid symlink attacks in the "embedded tests", which are not enabled
878 by default and should never be enabled in production builds of dbus.
879 (fd.o #99828, Simon McVittie)
881 • Fix the implementation of re-enabling a timeout so that its
882 countdown is restarted as intended, instead of continually
883 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
885 • When receiving a message with file descriptors, do not start reading
886 the beginning of the next message, so that only one such message
887 is processed at a time. In conjunction with the fix for #95619
888 this means that processes sending many file descriptors, such as
889 systemd-logind on a system that receives very rapid ssh connections,
890 are not treated as abusive and kicked off the bus. Revert the previous
891 workaround that special-cased uid 0.
892 (fd.o #95263, LP#1591411; Simon McVittie)
894 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
895 for Windows with CMake (fd.o #99586, Ralf Habacker)
897 • Do not set Unix-specific variables when targeting Windows
898 (fd.o #99586, Ralf Habacker)
900 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
901 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
903 • Use relative install locations in CMake on Unix to respect DESTDIR,
904 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
906 • Install dbus-arch-deps.h correctly when using CMake
907 (fd.o #99586, #99721; Ralf Habacker)
909 • Improve argument validation for `dbus-test-tool spam`
910 (ffd.o #99693, Coverity #54759; Philip Withnall)
912 • Don't shift by a negative integer if a hash table becomes monstrously
913 large (fd.o #99641, Coverity #54682; Philip Withnall)
915 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
916 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
918 • Remove an unnecessary NULL check
919 (fd.o #99642, Coverity #141062; Philip Withnall)
921 • Improve error handling in unit tests and dbus-send
922 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
923 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,
924 #54710, #54711, #54714, #54715, #54718, #54721, #54724, #54726,
925 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
927 • Do not print verbose messages' timestamps to stderr if the actual message
928 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
930 D-Bus 1.11.8 (2016-11-28)
933 The “panics in the face of breakfast foods” release.
935 Build-time configuration:
937 • The new --enable-debug configure option provides an easy way to
938 enable debug symbols, disable optimization and/or enable profiling.
940 • The --enable-compile-warnings configure option can be used to control
943 • The --disable-compiler-optimisations configure option is no longer
944 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
948 • D-Bus Specification version 0.30
949 · Define the jargon term "activation" more clearly
950 · Define the jargon term "auto-starting", which is one form of activation
951 · Document the optional SystemdService key in service files
952 · Use versioned interface and bus names in most examples
953 · Clarify intended behaviour of Properties.GetAll
954 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
956 • Fix and enable a lot of compiler warnings to improve future code
957 quality. This might incidentally also fix some environment variable
959 · In particular, printf-style functions in the libdbus API are now annotated
960 with __attribute__((__format__(__printf__, *, *))) when compiling with
961 gcc or clang. This might make printf bugs in other software visible
963 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
964 Thomas Zimmermann, Simon McVittie)
966 • When running with AppArmor mediation (for example using Ubuntu's patched
967 Linux kernel), clients can no longer auto-start services unless they would
968 have been able to send the auto-starting message to the service after it
969 starts. StartServiceByName() is unaffected, and continues to be allowed by
970 default in AppArmor's <abstractions/dbus-strict> and
971 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
975 • Work around an undesired effect of the fix for CVE-2014-3637
976 (fd.o #80559), in which processes that frequently send fds, such as
977 logind during a flood of new PAM sessions, can get disconnected for
978 continuously having at least one fd "in flight" for too long;
979 dbus-daemon interprets that as a potential denial of service attack.
980 The workaround is to disable that check for uid 0 process such as
981 logind, with a message in the system log. The bug remains open while
982 we look for a more general solution.
983 (fd.o #95263, LP#1591411; Simon McVittie)
985 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
986 was disabled at compile time. That test is not expected to work
987 in that configuration. (fd.o #98665, Simon McVittie)
989 D-Bus 1.11.6 (2016-10-10)
992 The “darkly whimsical” release.
996 • Do not treat ActivationFailure message received from root-owned systemd
997 name as a format string. In principle this is a security vulnerability,
998 but we do not believe it is exploitable in practice, because only
999 privileged processes can own the org.freedesktop.systemd1 bus name, and
1000 systemd does not appear to send activation failures that contain "%".
1002 Please note that this probably *was* exploitable in dbus versions
1003 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
1004 the time was only thought to be a denial of service vulnerability
1005 (CVE-2015-0245). If you are still running one of those versions,
1006 patch or upgrade immediately.
1008 (fd.o #98157, Simon McVittie)
1012 • D-Bus Specification version 0.29
1013 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
1014 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
1016 • Log to syslog when we exceed various anti-DoS limits, and add test
1017 coverage for them (fd.o #86442, Simon McVittie)
1019 • Improve syslog handling so that _dbus_warn() and similar warnings
1020 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
1021 and log to syslog (instead of /dev/null) when dbus-daemon is started by
1022 dbus-launch. (fd.o #97009, Simon McVittie)
1024 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
1025 (fd.o #89011, Philip Withnall)
1027 • When logging messages about service activation, mention which peer
1028 requested the activation (fd.o #68212, Philip Withnall)
1030 • On Linux, mention the LSM label (if available) whenever we print
1031 debug information about a peer (fd.o #68212, Philip Withnall)
1035 • Harden dbus-daemon against malicious or incorrect ActivationFailure
1036 messages by rejecting them if they do not come from a privileged
1037 process, or if systemd activation is not enabled
1038 (fd.o #98157, Simon McVittie)
1040 • Avoid undefined behaviour when setting reply serial number without going
1041 via union DBusBasicValue (fd.o #98035, Marc Mutz)
1043 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
1044 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
1046 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
1048 D-Bus 1.11.4 (2016-08-15)
1051 The “copper pickaxe” release.
1055 • Building from git (but not from tarballs) now requires
1056 macros from the GNU Autoconf Archive, for example the autoconf-archive
1057 package in Debian or Fedora derivatives.
1059 Build-time configuration:
1061 • The option to enable coverage instrumentation has changed from
1062 --enable-compiler-coverage to --enable-code-coverage.
1066 • D-Bus Specification version 0.28
1067 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
1069 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
1070 minimizing failed connections under heavy load
1071 (fd.o #95264, Lennart Poettering)
1073 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
1075 • Use the same regression tests for subprocess starting on Unix and Windows
1076 (fd.o #95191, Ralf Habacker)
1078 • Print timestamps and thread IDs in verbose messages
1079 (fd.o #95191, Ralf Habacker)
1081 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
1082 pointing to /dev/null (fd.o #97008, Simon McVittie)
1084 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
1085 (fd.o #88922, Thomas Zimmermann)
1089 • On Windows, fix a memory leak in replacing the installation prefix
1090 (fd.o #95191, Ralf Habacker)
1092 • On Linux, when dbus-daemon is run with reduced susceptibility to the
1093 OOM killer (typically via systemd), do not let child processes inherit
1094 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
1096 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
1097 even if a parent process incorrectly starts them with stdin, stdout
1098 and/or stderr closed (fd.o #97008, Simon McVittie)
1100 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
1101 contains a semicolon (fd.o #94746, Thiago Macieira)
1103 • Fix memory leaks and thread safety in subprocess starting on Windows
1104 (fd.o #95191, Ralf Habacker)
1106 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
1107 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
1109 • In tests that exercise correct handling of crashing D-Bus services,
1110 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
1112 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
1114 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
1115 in some test cases (fd.o #93909, Nick Lewycky)
1117 • Add assertions to reassure a static analysis tool
1118 (fd.o #93210, Deepika Aggarwal)
1120 • Be explicit about enum comparison when loading XML
1121 (fd.o #93205, Deepika Aggarwal)
1123 • update-activation-environment: produce better diagnostics on error
1124 (fd.o #96653, Simon McVittie)
1126 • Avoid various compiler warnings with gcc 6
1127 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
1129 • On Unix when configured to use the system log, report as "dbus-daemon",
1130 not as "dbus" (fd.o #97009, Simon McVittie)
1132 • During unit tests, reduce the amount we write to the system log
1133 (fd.o #97009, Simon McVittie)
1135 D-Bus 1.11.2 (2016-03-07)
1138 The “pneumatic drill vs. Iron Maiden” release.
1142 • Enable "large file support" on systems where it exists: dbus-daemon
1143 is not expected to open large files, but it might need to stat files
1144 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
1146 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
1147 which might result in a pedantic C compiler not copying the entire contents
1148 of a DBusMessageIter; statically assert that this is not an ABI change
1149 in practice (fd.o #94136, Simon McVittie)
1151 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
1152 (fd.o #94244, Dmitri Iouchtchenko)
1154 • Correctly report test failures in C tests from run-test.sh
1155 (fd.o #93379; amit tewari, Simon McVittie)
1157 • When tests are enabled, run all the marshal-validate tests, not just
1158 the even-numbered ones (fd.o #93908, Nick Lewycky)
1160 • Correct the expected error from one marshal-validate test, which was
1161 previously not run due to the above bug (fd.o #93908, Simon McVittie)
1163 • Fix compilation under CMake when embedded tests are disabled
1164 (fd.o #94094, eric.hyer)
1168 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
1169 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
1171 • When building with CMake, use the same gcc/clang warnings as under Autotools,
1172 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
1174 • test/name-test: make C tests produce TAP output and run them directly, not
1175 via run-test.sh (fd.o #92899, Simon McVittie)
1177 • Under CMake when cross-compiling for Windows on Unix, run the tests
1178 under Wine even if binfmt_misc support is not available
1179 (fd.o #88966, Ralf Habacker)
1181 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
1182 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
1184 • Factor out some functions that will be needed in future for a Windows
1185 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
1187 D-Bus 1.11.0 (2015-12-02)
1190 The “peppermint deer” release.
1194 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
1195 C99 constants such as PRId64 and PRIu64.
1199 • D-Bus Specification version 0.27
1200 · Specify that services should not reply if NO_REPLY_EXPECTED was used
1201 (fd.o #75749, Lars Uebernickel)
1203 • Add a script to do continuous-integration builds, and metadata to run it
1204 on travis-ci.org. To use this, clone the dbus git repository on GitHub
1205 and set it up with travis-ci.org; the only special setting needed is
1206 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
1208 • If dbus-daemon is run with --systemd-activation, do not require
1209 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
1213 • Re-order dbus-daemon startup so that on SELinux systems, the thread
1214 that reads AVC notifications retains the ability to write to the
1215 audit log (fd.o #92832, Laurent Bigonville)
1217 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
1219 • When using the Monitoring interface, match messages' destinations
1220 (fd.o #92074, Simon McVittie)
1222 • On Linux with systemd, stop installing a reference to the obsolete
1223 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
1226 • On Windows, when including configuration files with <include> or
1227 <includedir>, apply the same relocation as for the Exec paths
1228 in .service files (fd.o #92028, Simon McVittie)
1230 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
1232 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
1234 D-Bus 1.10.6 (2015-12-01)
1237 The “marzipan beetles” release.
1241 • On Unix when running tests as root, don't assert that root and
1242 the dbus-daemon user can still call UpdateActivationEnvironment;
1243 assert that those privileged users can call BecomeMonitor instead
1244 (fd.o #93036, Simon McVittie)
1246 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
1249 • On Windows Autotools builds, don't run tests that rely on
1250 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
1252 D-Bus 1.10.4 (2015-11-17)
1255 The “Frostburn Canyon” release.
1259 • GetConnectionCredentials, GetConnectionUnixUser and
1260 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
1261 will now return details of the dbus-daemon itself. This is required
1262 to be able to call SetEnvironment on systemd.
1263 (fd.o #92857, Jan Alexander Steffens)
1267 • Make UpdateActivationEnvironment always fail with AccessDenied on the
1268 system bus. Previously, it was possible to configure it so root could
1269 call it, but the environment variables were not actually used,
1270 because the launch helper would discard them.
1271 (fd.o #92857, Jan Alexander Steffens)
1273 • On Unix with --systemd-activation on a user bus, make
1274 UpdateActivationEnvironment pass on its arguments to systemd's
1275 SetEnvironment method, solving inconsistency between the environments
1276 used for traditional activation and systemd user-service activation.
1277 (fd.o #92857, Jan Alexander Steffens)
1279 • On Windows, don't crash if <syslog/> or --syslog is used
1280 (fd.o #92538, Ralf Habacker)
1282 • On Windows, fix a memory leak when setting a DBusError from a Windows
1283 error (fd.o #92721, Ralf Habacker)
1285 • On Windows, don't go into infinite recursion if we abort the process
1286 with backtraces enabled (fd.o #92721, Ralf Habacker)
1288 • Fix various failing tests, variously on Windows and cross-platform:
1289 · don't test system.conf features (users, groups) that only make sense
1290 on the system bus, which is not supported on Windows
1291 · don't call _dbus_warn() when we skip a test, since it is fatal
1292 · fix computation of expected <standard_session_servicedirs/>
1293 · when running TAP tests, translate newlines to Unix format, fixing
1294 cross-compiled tests under Wine on Linux
1295 · don't stress-test refcounting under Wine, where it's really slow
1296 · stop assuming that a message looped-back to the test will be received
1298 · skip some system bus tests on Windows since they make no sense there
1299 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
1301 D-Bus 1.10.2 (2015-10-26)
1304 The “worst pies in London” release.
1308 • Correct error handling for activation: if there are multiple attempts
1309 to activate the same service and it fails immediately, the first attempt
1310 would get the correct reply, but the rest would time out. We now send
1311 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
1313 • If BecomeMonitor is called with a syntactically invalid match rule,
1314 don't crash with an assertion failure, fixing a regression in 1.9.10.
1315 This was not exploitable as a denial of service, because the check
1316 for a privileged user is done first. (fd.o #92298, Simon McVittie)
1318 • On Linux with --enable-user-session, add the bus address to the
1319 environment of systemd services for better backwards compatibility
1320 (fd.o #92612, Jan Alexander Steffens)
1322 • On Windows, fix the logic for replacing the installation prefix
1323 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
1325 • On Windows, if installed in the conventional layout with ${prefix}/etc
1326 and ${prefix}/share, use relative paths between bus configuration files
1327 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
1329 • Make more of the regression tests pass in Windows builds (fd.o #92538,
1332 D-Bus 1.10.0 (2015-08-25)
1337 This is a new stable branch, recommended for use in OS distributions.
1341 • distribute test/tap-test.sh.in, even if the tarball was built without
1342 tests enabled (fd.o #91684, Simon McVittie)
1343 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
1345 Summary of major changes since 1.8.0:
1347 • The basic setup for the well-known system and session buses is
1348 now done in read-only files in ${datadir} (normally /usr/share).
1349 See the NEWS entry for 1.9.18 for details.
1351 • AppArmor integration has been merged, with features similar to the
1352 pre-existing SELinux integration. It is mostly compatible with the
1353 patches previously shipped by Ubuntu, with one significant change:
1354 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
1355 by GetConnectionCredentials and was not included.
1357 • The --enable-user-session configure option can be enabled
1358 by OS integrators intending to use systemd to provide a session bus
1359 per user (in effect, treating all concurrent graphical and non-graphical
1360 login sessions as one large session).
1362 • The new listenable address mode "unix:runtime=yes" listens on
1363 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
1364 user session. libdbus and "dbus-launch --autolaunch" will connect to
1365 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
1368 • All executables are now dynamically linked to libdbus-1.
1369 Previously, some executables, most notably dbus-daemon, were statically
1370 linked to a specially-compiled variant of libdbus. This results in
1371 various private functions in the _dbus namespace being exposed by the
1372 shared library. These are not API, and must not be used outside
1373 the dbus source tree.
1375 • On platforms with ELF symbol versioning, all public symbols
1376 are versioned LIBDBUS_1_3.
1380 • org.freedesktop.DBus.GetConnectionCredentials returns
1381 LinuxSecurityLabel where supported
1382 • org.freedesktop.DBus.Monitoring interface (privileged)
1383 · BecomeMonitor method supersedes match rules with eavesdrop=true,
1384 which are now deprecated
1385 • org.freedesktop.DBus.Stats interface (semi-privileged)
1386 · now enabled by default
1387 · new GetAllMatchRules method
1388 • org.freedesktop.DBus.Verbose interface (not normally compiled)
1389 · toggles the effect of DBUS_VERBOSE
1394 • dbus-update-activation-environment
1396 New optional dependencies:
1398 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
1399 • Complete documentation requires Ducktype and yelp-tools
1400 • Full test coverage requires GLib 2.36 and PyGI
1401 • AppArmor integration requires libapparmor and optionally libaudit
1403 Dependencies removed:
1407 D-Bus 1.9.20 (2015-08-06)
1410 The “Remember Tomorrow” release.
1412 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
1417 • Don't second-guess what the ABI of poll() is, allowing it to be used
1418 on Integrity RTOS and other unusual platforms (fd.o #90314;
1419 Rolland Dudemaine, Simon McVittie)
1421 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
1422 both enabled (fd.o #89225, Simon McVittie)
1424 • Log audit events for AppArmor/SELinux policy violations whenever
1425 we have CAP_AUDIT_WRITE, even if not the system bus
1426 (fd.o #83856, Laurent Bigonville)
1428 D-Bus 1.9.18 (2015-07-21)
1431 The “Pirate Elite” release.
1433 Configuration changes:
1435 • The basic setup for the well-known system and session buses is now done
1436 in read-only files in ${datadir}, moving a step closer to systems
1437 that can operate with an empty /etc directory. In increasing order
1440 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
1441 the default message policies.
1442 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
1443 dbus still installs a trivial version of each, for documentation
1444 purposes; putting configuration directives in these files is deprecated.
1445 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
1446 to install "drop-in" configuration snippets (any packages
1447 using those directories should explicitly depend on at least this
1449 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
1450 or third-party software to install "drop-in" configuration snippets
1451 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
1454 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
1455 and "s*" refers to either system or session as appropriate.
1457 (fd.o #89280, Dimitri John Ledkov)
1461 • Fix a memory leak when GetConnectionCredentials() succeeds
1462 (fd.o #91008, Jacek Bukarewicz)
1464 • Ensure that dbus-monitor does not reply to messages intended for others,
1465 resulting in its own disconnection (fd.o #90952, Simon McVittie)
1467 D-Bus 1.9.16 (2015-05-14)
1470 The “titanium barns” release.
1474 • Automake 1.13 is now required when compiling from git or modifying
1479 • On Unix platforms, change the default configuration for the session bus
1480 to only allow EXTERNAL authentication (secure kernel-mediated
1481 credentials-passing), as was already done for the system bus.
1483 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
1484 unpredictable pseudo-random numbers.
1486 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
1487 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1488 NFS or similar, you will need to reconfigure the session bus to accept
1489 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1492 (fd.o #90414, Simon McVittie)
1494 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1495 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1496 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1497 occurs, instead of silently falling back to low-entropy pseudorandom
1498 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1502 • Add dbus_message_iter_get_element_count()
1503 (fd.o #30350; Christian Dywan, Simon McVittie)
1505 • Introduce new internal DBusSocket and DBusPollable types so we can
1506 stop treating the Windows SOCKET type as if it was int. DBusSocket
1507 is specifically a socket, cross-platform. DBusPollable is whatever
1508 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1509 (fd.o #89444; Ralf Habacker, Simon McVittie)
1511 • All regression tests now output TAP <https://testanything.org/>
1512 (fd.o #89846, Simon McVittie)
1514 • Internal APIs consistently use signed values for timestamps
1515 (fd.o #18494, Peter McCurdy)
1517 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1518 (fd.o #88812, Simon McVittie)
1520 • Clean up a lot of compiler warnings
1521 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1525 • Add locking to DBusCounter's reference count and notify function
1526 (fd.o #89297, Adrian Szyndela)
1528 • Ensure that DBusTransport's reference count is protected by the
1529 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1531 • Correctly release DBusServer mutex before early-return if we run out
1532 of memory while copying authentication mechanisms (fd.o #90021,
1535 • Make dbus-test-tool and dbus-update-activation-environment portable
1536 to Windows (fd.o #90089, Ralf Habacker)
1538 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1539 Ralf Habacker, Simon McVittie)
1541 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1544 • Clean up some memory and fd leaks in test code and tools
1545 (fd.o #90021, Ralf Habacker)
1547 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1548 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1550 • CMake generates a versioned shared library even if the revision is 0,
1551 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1553 D-Bus 1.9.14 (2015-03-02)
1556 The “don't stand in the poison cloud” release.
1560 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1561 were previously linked to a static version of libdbus.
1563 • The tests no longer require dbus-glib in order to exercise the libdbus
1564 shared library; they are always linked to libdbus now.
1566 Build-time configuration:
1568 • The new --enable-user-session option, off by default, can be enabled
1569 by OS integrators intending to use systemd to provide a session bus
1570 per user (in effect, treating all concurrent graphical and non-graphical
1571 login sessions as one large session)
1575 • All executables are now linked dynamically to libdbus.
1576 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1578 • On platforms that support them (GNU libc and possibly others),
1579 libdbus now has versioned symbols for its public API.
1580 All public symbols (visible in the header files) are currently
1581 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1582 dbus_internal have a version that changes with each release, and
1583 must not be used by applications. (also fd.o #83115)
1585 • New listenable address mode "unix:runtime=yes" which listens on
1586 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1587 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1589 • Add optional systemd units for a per-user bus listening on
1590 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1592 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1593 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1596 • New dbus-update-activation-environment tool uploads environment
1597 variables to "dbus-daemon --session" and optionally "systemd --user",
1598 primarily as a way to keep the per-user bus compatible with
1599 distributions' existing X11 login scripts (also fd.o #61301)
1601 • <includedir/> elements in dbus-daemon configuration are now silently
1602 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1604 • Add microsecond-resolution timestamps to the default output of
1605 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1609 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1610 (fd.o #89222, Simon McVittie)
1612 D-Bus 1.9.12 (2015-02-19)
1615 The “monster lasagna” release.
1619 • Ducktype and yelp-tools are now required to build complete documentation
1620 (they are optional for normal builds).
1624 • D-Bus Specification version 0.26
1625 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1626 · document the BecomeMonitor method
1628 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1629 (fd.o #89041; Tyler Hicks, Simon McVittie)
1631 • On Linux, add support for AppArmor mediation of message sending and
1632 receiving and name ownership (paralleling existing SELinux mediation
1633 support), and eavesdropping (a new check, currently AppArmor-specific)
1634 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1636 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1637 that have printable ASCII contents; we previously only did this for
1638 unterminated bytestrings (fd.o #89109, Simon McVittie)
1640 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1642 • On Windows, add WindowsSID to GetConnectionCredentials
1643 (fd.o #54445, Ralf Habacker)
1645 • Improve clarity of dbus-monitor --profile output and add more columns
1646 (fd.o #89165, Ralf Habacker)
1648 • Add a man page for dbus-test-tool, and build it under CMake as well
1649 as Autotools (fd.o#89086, Simon McVittie)
1651 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1652 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1653 (fd.o #88896, Ralf Habacker)
1657 • Reduce the number of file descriptors used in the fd-passing test,
1658 avoiding failure under the default Linux fd limit, and automatically
1659 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1661 D-Bus 1.9.10 (2015-02-09)
1664 The “sad cyborgs” release.
1666 Security fixes merged from 1.8.16:
1668 • Do not allow non-uid-0 processes to send forged ActivationFailure
1669 messages. On Linux systems with systemd activation, this would
1670 allow a local denial of service: unprivileged processes could
1671 flood the bus with these forged messages, winning the race with
1672 the actual service activation and causing an error reply
1673 to be sent back when service auto-activation was requested.
1674 This does not prevent the real service from being started,
1675 so the attack only works while the real service is not running.
1676 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1680 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1681 similar tools receive messages without altering the security properties
1682 of the system bus, by calling the new BecomeMonitor method on a
1683 private connection. This bypasses the normal <allow> and <deny> rules
1684 entirely, so to preserve normal message-privacy assumptions, only root
1685 is allowed to do this on the system bus. Restricted environments,
1686 such as Linux with LSMs, should lock down access to the Monitoring
1687 interface. (fd.o #46787, Simon McVittie)
1689 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1690 dbus-daemon supports it and access permissions allow it.
1691 It still supports the previous approach ("eavesdropping" match rules)
1692 for compatibility with older bus daemons. (fd.o #46787, Simon)
1694 • dbus-monitor can now log the message stream as binary data for later
1695 analysis, with either no extra framing beyond the normal D-Bus headers,
1696 or libpcap-compatible framing treating each D-Bus message
1697 as a captured packet. (fd.o #46787, Simon)
1701 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1703 • On Unix, forcibly terminate regression tests after 60 seconds to
1704 prevent them from blocking continuous integration frameworks
1705 (fd.o #46787, Simon)
1707 D-Bus 1.9.8 (2015-02-03)
1710 The “all the types of precipitation” release.
1714 • full test coverage now requires GLib 2.36
1715 • full test coverage now requires PyGI (PyGObject 3,
1716 "import gi.repository.GObject") instead of the
1717 obsolete PyGObject 2 ("import gobject")
1721 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1723 • better regression test coverage, including systemd activation
1724 (fd.o #57952, #88810; Simon McVittie)
1728 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1729 turned off (fd.o #88808, Simon McVittie)
1731 • TCP sockets on Windows no longer fail to listen approximately 1 time
1732 in 256, caused by a logic error that should have always made it fail but
1733 was mitigated by incorrect endianness for the port number
1734 (fd.o #87999, Ralf Habacker)
1736 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1738 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1739 previous 64, completing a previous fix which only worked under
1740 Autotools (fd.o #71297, Ralf Habacker)
1742 • on Windows, if the IP family is unspecified only use IPv4,
1743 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1745 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1747 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1749 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1752 D-Bus 1.9.6 (2015-01-05)
1755 The “I do have a bread knife” release.
1759 • Do not allow calls to UpdateActivationEnvironment from uids other than
1760 the uid of the dbus-daemon. If a system service installs unsafe
1761 security policy rules that allow arbitrary method calls
1762 (such as CVE-2014-8148) then this prevents memory consumption and
1763 possible privilege escalation via UpdateActivationEnvironment.
1765 We believe that in practice, privilege escalation here is avoided
1766 by dbus-daemon-launch-helper sanitizing its environment; but
1767 it seems better to be safe.
1769 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1770 on object paths other than /org/freedesktop/DBus. Some system services
1771 install unsafe security policy rules that allow arbitrary method calls
1772 to any destination, method and interface with a specified object path;
1773 while less bad than allowing arbitrary method calls, these security
1774 policies are still harmful, since dbus-daemon normally offers the
1775 same API on all object paths and other system services might behave
1780 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1781 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1783 D-Bus 1.9.4 (2014-11-24)
1786 The “extra-sturdy caramel” release.
1790 • Partially revert the CVE-2014-3639 patch by increasing the default
1791 authentication timeout on the system bus from 5 seconds back to 30
1792 seconds, since this has been reported to cause boot regressions for
1793 some users, mostly with parallel boot (systemd) on slower hardware.
1795 On fast systems where local users are considered particularly hostile,
1796 administrators can return to the 5 second timeout (or any other value
1797 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1800 <limit name="auth_timeout">5000</limit>
1803 (fd.o #86431, Simon McVittie)
1805 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1806 (fd.o #86431, Simon McVittie)
1808 • Send back an AccessDenied error if the addressed recipient is not allowed
1809 to receive a message (and in builds with assertions enabled, don't
1810 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1812 D-Bus 1.9.2 (2014-11-10)
1815 The “structurally unsound flapjack” release.
1819 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1820 so that CVE-2014-3636 part A cannot exhaust the system bus'
1821 file descriptors, completing the incomplete fix in 1.8.8.
1822 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1826 • D-Bus Specification version 0.25
1827 · new value 'const' for EmitsChangedSignal annotation

1829 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1830 (fd.o #83449; Lennart Poettering, Simon McVittie)
1831 · annotate table of types with reserved/basic/container, and for
1832 basic types, fixed/string-like
1833 · clarify arbitrary limits by quoting them in mebibytes
1835 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1836 (fd.o #83449, Simon McVittie)
1838 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1839 useful for debugging and performance testing:
1840 · dbus-test-tool spam: send repeated messages
1841 · dbus-test-tool echo: send an empty reply for all method calls
1842 · dbus-test-tool black-hole: do not reply to method calls
1843 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1845 • Add support for process ID in credentials-passing on NetBSD
1846 (fd.o #69702, Patrick Welche)
1848 • Add an example script to find potentially undesired match rules
1849 (fd.o #84598, Alban Crequy)
1851 • Document the central assumption that makes our use of credentials-passing
1852 secure (fd.o #83499, Simon McVittie)
1854 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1855 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1860 • Use a less confusing NoReply message when disconnected with a reply pending
1861 (fd.o #76112, Simon McVittie)
1863 • Make the .pc file relocatable by letting pkg-config do all variable
1864 expansion itself (fd.o #75858, Руслан Ижбулатов)
1866 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1867 (fd.o #85563, Patrick Welche)
1869 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1871 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1872 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1874 • Do not fail the tests if a parent process has leaked non-close-on-exec
1875 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1877 • Do not fail the tests on Unix platforms with incomplete
1878 credentials-passing support, but do fail if we can't pass credentials
1879 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1880 (fd.o #69702, Simon McVittie)
1882 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1883 when building with cmake, and expand test coverage there
1884 (fd.o #73689; Ralf Habacker, Simon McVittie)
1886 D-Bus 1.9.0 (2014-10-01)
1889 The “tiered cheeses” release.
1893 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1894 requires either the libsystemd or libsd-daemon shared library, dropping the
1895 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1897 Build-time configuration changes:
1899 • The Stats interface is now enabled by default, and locked-down to
1900 root-only on the system bus. Configure with --disable-stats
1901 to disable it altogether on memory- or disk-constrained systems,
1902 or see ${docdir}/examples/ to open it up to non-root users on the
1903 system bus or restrict access on the session bus.
1904 (fd.o #80759; Simon McVittie, Alban Crequy)
1906 • The CMake build system now builds the same shared library name as Autotools
1907 on at least Linux and Windows:
1908 - on Linux (and perhaps other Unix platforms), it previously built
1909 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1910 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1911 - on Windows, it previously built either libdbus-1.dll (release) or
1912 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1913 libdbus-1.dll for compatibility with older applications.
1914 (fd.o #74117, Ralf Habacker)
1918 • D-Bus Specification version 0.24
1919 · document how to quote match rules (fd.o #24307, Simon McVittie)
1920 · explicitly say that most message types never expect a reply
1921 regardles of whether they have NO_REPLY_EXPECTED
1922 (fd.o #75749, Simon McVittie)
1924 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
1925 initial latency (fd.o #75544, Matt Hoosier)
1927 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
1928 (fd.o #69702, Patrick Welche)
1930 • in dbus-monitor, print more information about file descriptors
1931 (fd.o #80603, Alban Crequy)
1933 • do not install system bus configuration if built for Windows
1934 (fd.o #83583; Ralf Habacker, Simon McVittie)
1936 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
1938 • Add a regression test for file descriptor passing (fd.o #83622,
1943 • fix an incorrect error message if a Unix socket path is too long
1944 (fd.o #73887, Antoine Jacoutot)
1946 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
1947 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
1949 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
1950 in ps(1) (fd.o #69716, Chengwei Yang)
1952 • avoid calling poll() with timeout < -1, which is considered invalid
1953 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
1955 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
1956 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
1957 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
1959 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
1961 • Documentation improvements
1962 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
1964 • in dbus-monitor, do not leak file descriptors that we have monitored
1965 (fd.o #80603, Alban Crequy)
1967 • Set the close-on-exec flag for the inotify file descriptor, even
1968 if built with CMake or older libc (fd.o #73689, Simon McVittie)
1970 • Remove some LGPL code from the Windows dbus-daemon
1971 (fd.o #57272, Ralf Habacker)
1973 D-Bus 1.8.8 (2014-09-16)
1976 The "smashy smashy egg man" release.
1980 • Do not accept an extra fd in the padding of a cmsg message, which
1981 could lead to a 4-byte heap buffer overrun.
1982 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1984 • Reduce default for maximum Unix file descriptors passed per message
1985 from 1024 to 16, preventing a uid with the default maximum number of
1986 connections from exhausting the system bus' file descriptors under
1987 Linux's default rlimit. Distributors or system administrators with a
1988 more restrictive fd limit may wish to reduce these limits further.
1990 Additionally, on Linux this prevents a second denial of service
1991 in which the dbus-daemon can be made to exceed the maximum number
1992 of fds per sendmsg() and disconnect the process that would have
1994 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1996 • Disconnect connections that still have a fd pending unmarshalling after
1997 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1998 removing the possibility of creating an abusive connection that cannot be
1999 disconnected by setting up a circular reference to a connection's
2001 (CVE-2014-3637, fd.o #80559; Alban Crequy)
2003 • Reduce default for maximum pending replies per connection from 8192 to 128,
2004 mitigating an algorithmic complexity denial-of-service attack
2005 (CVE-2014-3638, fd.o #81053; Alban Crequy)
2007 • Reduce default for authentication timeout on the system bus from
2008 30 seconds to 5 seconds, avoiding denial of service by using up
2009 all unauthenticated connection slots; and when all unauthenticated
2010 connection slots are used up, make new connection attempts block
2011 instead of disconnecting them.
2012 (CVE-2014-3639, fd.o #80919; Alban Crequy)
2016 • Check for libsystemd from systemd >= 209, falling back to
2017 the older separate libraries if not found (Umut Tezduyar Lindskog,
2020 • On Linux, use prctl() to disable core dumps from a test executable
2021 that deliberately raises SIGSEGV to test dbus-daemon's handling
2022 of that condition (fd.o #83772, Simon McVittie)
2024 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
2027 • Improve documentation for running tests on Windows (fd.o #41252,
2030 D-Bus 1.8.6 (2014-06-02)
2035 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
2036 the message. This prevents an attack in which a malicious client can
2037 make dbus-daemon disconnect a system service, which is a local
2039 (fd.o #80163, CVE-2014-3532; Alban Crequy)
2041 • Track remaining Unix file descriptors correctly when more than one
2042 message in quick succession contains fds. This prevents another attack
2043 in which a malicious client can make dbus-daemon disconnect a system
2045 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
2046 Simon McVittie, Alban Crequy)
2050 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
2051 attach to a session, kill the dbus-daemon as intended
2052 (fd.o #74698, Роман Донченко)
2054 D-Bus 1.8.4 (2014-06-10)
2059 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
2060 flaw in dbus-daemon, part of the reference implementation of D-Bus.
2061 Additionally, in highly unusual environments the same flaw could lead to
2062 a side channel between processes that should not be able to communicate.
2063 (CVE-2014-3477, fd.o #78979)
2065 D-Bus 1.8.2 (2014-04-30)
2068 The “nobody wants red” release.
2072 • in the CMake build system, add some hints for Linux users cross-compiling
2073 Windows D-Bus binaries to be able to run tests under Wine
2074 (fd.o #41252, Ralf Habacker)
2076 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
2080 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
2081 to /var/lib/dbus/machine-id instead of generating an entirely new ID
2082 (fd.o #77941, Simon McVittie)
2084 • if dbus-launch receives an X error very quickly, do not kill
2085 unrelated processes (fd.o #74698, Роман Донченко)
2087 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
2088 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
2090 • cope with \r\n newlines in regression tests, since on Windows,
2091 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
2093 D-Bus 1.8.0 (2014-01-20)
2096 The “Wolverine distrusts my printer” release.
2098 This starts a new stable branch. The 1.6.x branch is now considered to be
2099 outdated, and will only receive fixes for serious bugs such as security
2100 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
2101 are unlikely to get any more releases, but if distributors still need to
2102 support them, please share security patches via upstream.
2104 Summary of changes since 1.6.x:
2106 • libdbus always behaves as if dbus_threads_init_default() had been called
2107 (thread-safety by default)
2108 • new dbus-run-session tool, replacing certain misuses of dbus-launch
2109 • dbus-monitor can talk to outdated versions of dbus-daemon again
2110 • new org.freedesktop.DBus.GetConnectionCredentials method
2111 • GetConnectionUnixProcessID also works correctly on Windows, returning
2112 the Windows process ID
2113 • GetConnectionWindowsSID returns the correct SID on Windows
2114 • expat is required, libxml2 can no longer be used as a substitute
2115 • the userDB cache is required, and cannot be disabled
2116 • a 64-bit integer type (either int, long, long long or _int64) is required
2117 • better systemd-journald integration on Linux
2118 • fixed long-standing fd and array leaks when failing to parse a message
2119 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
2120 when using certain object-path allocation patterns, notably in Avahi
2121 • better defaults for Windows support
2122 • better CMake support
2123 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
2124 • the source language for the man pages is now Docbook XML
2126 Enhancements since 1.7.10:
2128 • Enhance the CMake build system to check for GLib and compile/run
2129 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
2133 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
2136 • fix compilation of systemd journal support on older systemd versions where
2137 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
2139 • fix compilation on older MSVC versions by including stdlib.h
2140 (fd.o #73455, Ralf Habacker)
2142 • Allow <allow_anonymous/> to appear in an included configuration file
2143 (fd.o #73475, Matt Hoosier)
2145 Test behaviour changes since 1.7.10:
2147 • If the tests crash with an assertion failure, they no longer default to
2148 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
2149 environment if you want the old behaviour.
2151 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
2152 can be run with an external dbus-daemon by setting
2153 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
2154 an unusually-configured dbus-daemon are skipped.
2156 D-Bus 1.7.10 (2014-01-06)
2159 The “weighted companion cube” release.
2161 This is a release candidate for D-Bus 1.8.
2163 D-Bus Specification 0.23:
2165 • don't require messages with no INTERFACE to be dispatched
2166 (fd.o #68597, Simon McVittie)
2168 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
2171 • define "listenable" and "connectable" addresses, and discuss
2172 the difference (fd.o #61303, Simon McVittie)
2176 • support printing Unix file descriptors in dbus-send, dbus-monitor
2177 (fd.o #70592, Robert Ancell)
2179 • don't install systemd units if --disable-systemd is given
2180 (fd.o #71818, Chengwei Yang)
2184 • don't leak memory on out-of-memory while listing activatable or
2185 active services (fd.o #71526, Radoslaw Pajak)
2187 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
2189 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
2191 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
2192 and DBUS__SEND_MSG are numerically equal to their values in the
2193 reference policy (fd.o #88719, osmond sun)
2195 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
2196 (fd.o #71366, Matt Fischer)
2198 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
2199 winsock2.h (fd.o #71405, Matt Fischer)
2201 • do not return failure from _dbus_read_nonce() with no error set,
2202 preventing a potential crash (fd.o #72298, Chengwei Yang)
2204 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
2205 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
2207 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
2208 which doesn't do anything anyway on at least Linux and FreeBSD
2209 (fd.o #69492, Simon McVittie)
2211 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
2212 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
2213 for credentials more correctly (fd.o #69492, Simon McVittie)
2215 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
2216 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
2219 • refresh cached policy rules for existing connections when bus
2220 configuration changes (fd.o #39463, Chengwei Yang)
2222 D-Bus 1.7.8 (2013-11-01)
2225 The “extreme hills” release.
2229 • If systemd support is enabled, libsystemd-journal is now required.
2233 • When activating a non-systemd service under systemd, annotate its
2234 stdout/stderr with its bus name in the Journal. Known limitation:
2235 because the socket is opened before forking, the process will still be
2236 logged as if it had dbus-daemon's process ID and user ID.
2237 (fd.o #68559, Chengwei Yang)
2239 • Document more configuration elements in dbus-daemon(1)
2240 (fd.o #69125, Chengwei Yang)
2244 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
2245 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
2247 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
2248 disallowed method calls to the audit log, fixing a regression in 1.7.6
2249 (fd.o #49062, Colin Walters)
2251 • path_namespace='/' in match rules incorrectly matched nothing; it
2252 now matches everything. (fd.o #70799, Simon McVittie)
2254 D-Bus 1.7.6 (2013-10-09)
2257 The “CSI Shrewsbury” release.
2259 Build-time configuration changes:
2261 • Directory change notification via dnotify on Linux is no longer
2262 supported; it hadn't compiled successfully since 2010 in any case.
2263 If you don't have inotify (Linux) or kqueue (*BSD), you will need
2264 to send SIGHUP to the dbus-daemon when its configuration changes.
2265 (fd.o #33001, Chengwei Yang)
2267 • Compiling with --disable-userdb-cache is no longer supported;
2268 it didn't work since at least 2008, and would lead to an extremely
2269 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
2272 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
2273 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
2274 with the Autotools build system. (fd.o #66142, Chengwei Yang)
2276 • --with-valgrind=auto enables Valgrind instrumentation if and only if
2277 valgrind headers are available. The default is still --with-valgrind=no.
2278 (fd.o #56925, Simon McVittie)
2282 • Platforms with no 64-bit integer type are no longer supported.
2283 (fd.o #65429, Simon McVittie)
2285 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
2287 • Full test coverage no longer requires dbus-glib, although the tests do not
2288 exercise the shared library (only a static copy) if dbus-glib is missing.

2304 • Be thread-safe by default on all platforms, even if
2305 dbus_threads_init_default() has not been called. For compatibility with
2306 older libdbus, library users should continue to call
2307 dbus_threads_init_default(): it is harmless to do so.
2308 (fd.o #54972, Simon McVittie)
2310 • Add GetConnectionCredentials() method (fd.o #54445, Simon)

2427 The “but is your thread-safety thread-safe?” release.
2431 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
2432 of service for system services. Vulnerability reported by Alexandru Cornea.
2437 • The Windows version of libdbus now contains a C++ source file, used
2438 to provide global initialization when the library is loaded.
2439 gcc (mingw*) users should ensure that g++ is also installed.
2441 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
2442 and was never the recommended option) has been removed. Expat is now a
2447 • It should now be safe to call dbus_threads_init_default() from any thread,
2448 at any time. Authors of loadable modules and plugins that use libdbus

2468 on a platform not defining LOG_PERROR, such as Solaris or QNX.
2469 This regressed in 1.7.0. (Simon)
2470 · Fix an assertion failure if we try to activate systemd services before
2471 systemd connects to the bus (fd.o #50199, Chengwei Yang)

2534 remains the recommended version for long-term-supported distributions
2535 or the upcoming GNOME 3.8 release.
2537 Build-time configuration changes:
2539 • The --with-dbus-session-bus-default-address configure option is no longer
2540 supported. Use the new --with-dbus-session-bus-connect-address and
2541 --with-dbus-session-bus-listen-address options instead. On Windows, you
2542 usually want them to have the same argument; on Unix, the defaults are
2545 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2546 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2547 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2549 • cmake/cross-compile.sh has been removed. Instead, please use a
2550 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2551 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2552 as documented in "info automake Cross-Compilation", and set
2553 PKG_CONFIG_PATH appropriately.
2557 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
2558 • man2html is no longer used.

2564 implements o.fd.DBus (fd.o #51865, Colin Walters)
2565 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
2566 · stop claiming that all basic types work just like INT32 (strings don't!)
2568 • The "source code" for the man pages is now Docbook XML, eliminating
2569 the outdated duplicate copies used when building with CMake.
2570 (fd.o #59805; Ralf Habacker, Simon McVittie)
2574 • In the activation helper, when compiled for tests, do not reset the system
2575 bus address, fixing the regression tests. (fd.o #52202, Simon)
2577 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
2578 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
2580 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

2599 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
2602 · The default session bus listening and connecting address is now
2603 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2604 and GDBus "out of the box". Use the configure options and cmake variables
2605 described above if you require a different autolaunch scope.
2606 (fd.o #38201, Simon McVittie)
2607 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
2609 • Create session.d, system.d directories under CMake (fd.o #41319,

2618 work to use __secure_getenv() as a followup to bug #52202
2619 broke certain configurations of gnome-keyring. Given
2620 the difficulty of making this work without extensive
2621 changes to gnome-keyring, use of __secure_getenv() is

2665 • Disconnect "developer mode" (assertions, verbose mode etc.) from
2666 Automake maintainer mode. D-Bus developers should now configure with
2667 --enable-developer. Automake maintainer mode is now on by default;
2668 distributions can disable it with --disable-maintainer-mode.
2669 (fd.o #34671, Simon McVittie)
2671 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,

2764 The "fire in Delerium" release.
2766 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2767 and SUSv2) is now required.
2769 • D-Bus Specification 0.19:
2770 · Formally define unique connection names and well-known bus names,
2771 and document best practices for interface, bus, member and error names,
2772 and object paths (fd.o #37095, Simon McVittie)

2809 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2810 setups where the default configuration must include <pidfile/> to avoid
2811 breaking traditional init, but the pid file is in fact unnecessary; use
2812 it under systemd to improve startup time a bit (fd.o #45520,

2823 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
2824 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
2825 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
2828 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
2832 · Replace our broken reimplementation of recursive mutexes, which has
2833 been broken since 2006, with an ordinary pthreads recursive mutex
2834 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2835 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2836 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2837 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2838 · When running under systemd, use it instead of ConsoleKit to check
2839 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2840 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2841 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2842 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2843 (fd.o #41218, Simon McVittie)
2844 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2845 helper doesn't obey environment variables to avoid privilege escalation
2846 attacks, so make the system bus follow the same rules
2847 (fd.o #21620, Simon McVittie)
2850 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2851 Jesper Dam, Ralf Habacker)
2852 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
2855 D-Bus 1.5.8 (2011-09-21)
2858 The "cross-metering" release.
2860 In addition to dead code removal and refactoring, this release contains all
2861 of the bugfixes from 1.4.16.
2863 • Clean up dead code, and make more warnings fatal in development builds
2864 (fd.o #39231, fd.o #41012; Simon McVittie)
2866 • If full test coverage is requested via --enable-tests, strictly require
2867 Python, pygobject and dbus-python, which are required by some tests; if not,
2868 and Python is missing, skip those tests rather than failing
2869 (fd.o #37847, Simon McVittie)
2871 • When using cmake, provide the same version-info API in the installed headers
2872 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2874 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
2876 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
2878 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
2881 • Fix duplicates in authors list (Ralf Habacker)
2883 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2884 (fd.o #39879, Chris Mayo)
2886 • Fix a small memory leak, and a failure to report errors, when updating
2887 a service file entry for activation (fd.o #39230, Simon McVittie)
2890 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2891 Brian Cameron, Simon McVittie)
2892 · On systems that use libcap-ng but not systemd, drop supplemental groups
2893 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2894 · Make the cmake build work again on GNU platforms (fd.o #29228,
2896 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
2897 like Solaris (fd.o #40313, Dagobert Michelsen)
2898 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2899 (fd.o #40235, Simon McVittie)
2900 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2901 (fd.o #39987, Simon McVittie)
2902 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2903 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2906 · Fix compilation on MSVC, which doesn't understand "inline" with its
2907 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2908 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2909 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2911 D-Bus 1.5.6 (2011-07-29)
2914 The "weird, gravy-like aftertaste" release.
2916 In addition to new features and refactoring, this release contains all of the
2917 bugfixes from 1.4.14.
2919 Potentially incompatible (Bustle and similar debugging tools will need
2920 changes to work as intended):
2922 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2923 different recipient) by mistake: eavesdroppers must now opt-in to this
2924 behaviour by putting "eavesdrop='true'" in the match rule, which will
2925 not have any practical effect on buses where eavesdropping is not allowed
2926 (fd.o #37890, Cosimo Alfarano)
2930 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2931 Cosimo Alfarano, Simon McVittie)
2932 · add the "eavesdrop" keyword to match rules
2933 · define eavesdropping, unicast messages and broadcast messages
2934 · stop claiming that match rules are needed to match unicast messages to you
2935 · promote the type system to be a top-level section
2937 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2938 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2939 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2941 • Consistently use atomic operations on everything that is ever manipulated
2942 via atomic ops, as was done for changes to DBusConnection's refcount in
2943 1.4.12 (fd.o #38005, Simon McVittie)
2945 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2948 • Make "make check" in a clean tree work, by not running tests until
2949 test data has been set up (fd.o #34405, Simon McVittie)
2951 • The dbus-daemon no longer busy-loops if it has a very large number of file
2952 descriptors (fd.o #23194, Simon McVittie)
2954 • Refactor message flow through dispatching to avoid locking violations if
2955 the bus daemon's message limit is hit; remove the per-connection link cache,
2956 which was meant to improve performance, but now reduces it (fd.o #34393,
2959 • Some cmake fixes (Ralf Habacker)
2961 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2962 Simon McVittie, Lennart Poettering)
2964 • Stop storing two extra byte order indicators in each D-Bus message
2965 (fd.o #38287, Simon McVittie)
2967 • Add an optional Stats interface which can be used to get statistics from
2968 a running dbus-daemon if enabled at configure time with --enable-stats
2969 (fd.o #34040, Simon McVittie)
2971 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2973 • Documentation (fd.o #36156, Simon McVittie):
2974 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2975 · install more documentation automatically, including man2html output
2976 · put dbus.devhelp in the right place (it must go in ${htmldir})
2979 · look for system services in /lib/dbus-1/system-services in addition to all
2980 the other well-known locations; note that this should always be /lib,
2981 even on platforms where shared libraries on the root FS would go in /lib64,
2982 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2983 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2985 • Windows-specific (Ralf Habacker):
2986 · fix use of a mutex for autolaunch server detection
2987 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2989 D-Bus 1.5.4 (2011-06-10)
2992 Security (local denial of service):
2994 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2995 local DoS if foreign-endian messages are relayed through the dbus-daemon
2996 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2997 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
3001 • The constant to use for an infinite timeout now has a name,
3002 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
3003 which can be used for source compatibility with older versions of libdbus.
3005 • If GLib and DBus-GLib are already installed, more tests will be built,
3006 providing better coverage. The new tests can also be installed via
3007 ./configure --enable-installed-tests
3008 for system integration testing, if required. (fd.o #34570, Simon McVittie)
3012 • Consistently use atomic operations for the DBusConnection's refcount,
3013 fixing potential threading problems (fd.o #38005, Simon McVittie)
3015 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
3016 small (300KiB on x86-64) and it frequently doesn't work in unusual
3017 toolchains. To optimize for minimum installed size, you should benchmark
3018 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
3019 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
3021 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
3022 (fd.o #35880, Timothy Redaelli)
3024 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
3025 when not using a DESTDIR (fd.o #37870, Simon McVittie)
3027 • Windows-specific changes:
3028 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
3030 D-Bus 1.5.2 (2011-06-01)
3033 The "Boar Hunter" release.
3035 Notes for distributors:
3037 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
3038 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
3039 toolchain supports it reliably, via something like:
3041 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
3043 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
3047 • D-Bus Specification v0.17
3048 · Reserve the extra characters used in signatures by GVariant
3049 (fd.o #34529, Simon McVittie)
3050 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
3051 • Don't force -fPIE: distributions and libtool know better than we do whether
3052 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
3053 • Allow --disable-gc-sections, in case your toolchain offers the
3054 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
3055 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
3056 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
3057 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
3058 • Ensure that maintainers upload documentation with the right permissions
3059 (fd.o #36130, Simon McVittie)
3060 • Don't force users of libdbus to be linked against -lpthread, -lrt
3061 (fd.o #32827, Simon McVittie)
3062 • Log system-bus activation information to syslog (fd.o #35705,
3064 • Log messages dropped due to quotas to syslog (fd.o #35358,
3066 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
3067 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
3068 (fd.o #35228, Lennart Poettering)
3069 • In the regression tests, don't report fds as "leaked" if they were open
3070 on startup (fd.o #35173, Simon McVittie)
3071 • Make dbus-monitor bail out if asked to monitor more than one bus,
3072 rather than silently using the last one (fd.o #26548, Will Thompson)
3073 • Clarify documentation (fd.o #35182, Simon McVittie)
3074 • Clean up minor dead code and some incorrect error handling
3075 (fd.o #33128, fd.o #29881; Simon McVittie)
3076 • Check that compiler options are supported before using them (fd.o #19681,
3079 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
3081 D-Bus 1.5.0 (2011-04-11)
3084 The "you never know when you need to tow something from your giant
3085 flying shark" release.
3087 • D-Bus Specification v0.16
3088 · Add support for path_namespace and arg0namespace in match rules
3089 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
3090 · Make argNpath support object paths, not just object-path-like strings,
3091 and document it better (fd.o #31818, Will Thompson)
3092 • Let the bus daemon implement more than one interface (fd.o #33757,
3094 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
3096 • Require user intervention to compile with missing 64-bit support
3097 (fd.o #35114, Simon McVittie)
3098 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
3099 • Raise UnknownObject instead of UnknownMethod for calls to methods on
3100 paths that are not part of the object tree, and UnknownInterface for calls
3101 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
3103 D-Bus 1.4.8 (2011-04-08)
3106 The "It's like the beginning of a lobster" release.
3108 • Rename configure.in to configure.ac, and update it to modern conventions
3109 (fd.o #32245; Javier Jardón, Simon McVittie)
3110 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
3112 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
3113 --disable-x11-autolaunch configure option to prevent it altogether
3114 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
3115 • Install the documentation, and an index for Devhelp (fd.o #13495,
3116 Debian #454142; Simon McVittie, Matthias Clasen)
3117 • If checks are not disabled, check validity of string-like types and
3118 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
3119 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
3120 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
3121 • Break up a huge conditional in config-parser so gcov can produce coverage
3122 data (fd.o #10887, Simon McVittie)
3123 • List which parts of the Desktop Entry specification are applicable to
3124 .service files (fd.o #19159, Sven Herzberg)
3125 • Don't suppress service activation if two services have the same Exec=
3126 (fd.o #35750, Colin Walters)
3128 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
3130 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
3131 (fd.o #32805, Mark Brand)
3133 D-Bus 1.4.6 (2010-02-17)
3136 The "1, 2, miss a few, 99, 100" release.
3138 • Remove unfinished changes intended to support GTest-based tests,
3139 which were mistakenly included in 1.4.4
3141 D-Bus 1.4.4 (2010-02-17)
3144 • Switch back to using even micro versions for stable releases; 1.4.1
3145 should have been called 1.4.2, so skip that version number
3146 • Don't leave bad file descriptors being watched when spawning processes,
3147 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
3148 also LP#656134, LP#680444, LP#713157)
3149 • Check for MSG_NOSIGNAL correctly
3150 • Fix failure to detect abstract socket support (fd.o #29895)
3151 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
3152 (fd.o #32262, NB#180486)
3153 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,

3179 D-Bus 1.4.1 (20 December 2010)
3182 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
3183 crash the bus. The existing restriction to 64-levels of nesting previously
3184 only applied to the static type signature; now it also applies to dynamic
3185 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
3187 • OS X portability fixes, including launchd support.
3188 • Windows autolaunch improvements.
3189 • Various bug fixes.
