1 dbus 1.12.20 (2020-07-02)
2 =========================
4 The “temporary nemesis” release.
8 • On Unix, avoid a use-after-free if two usernames have the same
9 numeric uid. In older versions this could lead to a crash (denial of
10 service) or other undefined behaviour, possibly including incorrect
11 authorization decisions if <policy group=...> is used.
12 Like Unix filesystems, D-Bus' model of identity cannot distinguish
13 between users of different names with the same numeric uid, so this
14 configuration is not advisable on systems where D-Bus will be used.
15 Thanks to Daniel Onaca.
16 (dbus#305, dbus!166; Simon McVittie)
20 • On Solaris and its derivatives, if a cmsg header is truncated, ensure
21 that we do not overrun the buffer used for fd-passing, even if the
23 (dbus#304, dbus!165; Andy Fiddaman)
25 dbus 1.12.18 (2020-06-02)
26 =========================
28 The “telepathic vines” release.
30 Denial of service fixes:
32 • CVE-2020-12049: If a message contains more file descriptors than can
33 be sent, close those that did get through before reporting error.
34 Previously, a local attacker could cause the system dbus-daemon (or
35 another system service with its own DBusServer) to run out of file
36 descriptors, by repeatedly connecting to the server and sending fds that

39 (dbus#294, GHSL-2020-057; Simon McVittie)
43 • Fix a crash when the dbus-daemon is terminated while one or more
44 monitors are active (dbus#291, dbus!140; Simon McVittie)
46 • The dbus-send(1) man page now documents --bus and --peer instead of
47 the old --address synonym for --peer, which has been deprecated since
48 the introduction of --bus and --peer in 1.7.6
49 (fd.o #48816, dbus!115; Chris Morin)
51 • Fix a wrong environment variable name in dbus-daemon(1)
52 (dbus#275, dbus!122; Mubin, Philip Withnall)
54 • Fix formatting of dbus_message_append_args example
55 (dbus!126, Felipe Franciosi)
57 • Avoid a test failure on Linux when built in a container as uid 0, but
58 without the necessary privileges to increase resource limits
59 (dbus!58, Debian #908092; Simon McVittie)
61 • When building with CMake, cope with libX11 in a non-standard location
62 (dbus!129, Tuomo Rinne)
64 dbus 1.12.16 (2019-06-11)
65 =========================
67 The “tree cat” release.
71 • CVE-2019-12749: Do not attempt to carry out DBUS_COOKIE_SHA1
72 authentication for identities that differ from the user running the
73 DBusServer. Previously, a local attacker could manipulate symbolic
74 links in their own home directory to bypass authentication and connect
75 to a DBusServer with elevated privileges. The standard system and
76 session dbus-daemons in their default configuration were immune to this
77 attack because they did not allow DBUS_COOKIE_SHA1, but third-party
78 users of DBusServer such as Upstart could be vulnerable.
79 Thanks to Joe Vennix of Apple Information Security.
80 (dbus#269, Simon McVittie)
82 dbus 1.12.14 (2019-05-17)
83 =========================
85 The “reclaimed floorboards” release.
89 • Raise soft fd limit to match hard limit, even if unprivileged.
90 This makes session buses with many clients, or with clients that make
91 heavy use of fd-passing, less likely to suffer from fd exhaustion.
92 (dbus!103, Simon McVittie)
96 • If a privileged dbus-daemon has a hard fd limit greater than 64K, don't
97 reduce it to 64K, ensuring that we can put back the original fd limits
98 when carrying out traditional (non-systemd) activation. This fixes a
99 regression with systemd >= 240 in which system services inherited
100 dbus-daemon's hard and soft limit of 64K fds, instead of the intended
101 soft limit of 1K and hard limit of 512K or 1M.
102 (dbus!103, Debian#928877; Simon McVittie)
104 • Fix build failures caused by an AX_CODE_COVERAGE API change in newer
105 autoconf-archive versions (dbus#249, dbus!88; Simon McVittie)
107 • Fix build failures with newer autoconf-archive versions that include
108 AX_-prefixed shell variable names (dbus#249, dbus!86; Simon McVittie)
110 • Parse section/group names in .service files according to the syntax
111 from the Desktop Entry Specification, rejecting control characters
112 and non-ASCII in section/group names (dbus#208, David King)
114 • Fix various -Wlogical-op issues that cause build failure with newer
115 gcc versions (dbus#225, dbus!109; David King)
117 • Don't assume we can set permissions on a directory, for the benefit of
118 MSYS and Cygwin builds (dbus#216, dbus!110; Simon McVittie)
120 • Don't overwrite PKG_CONFIG_PATH and related environment variables when
121 the pkg-config-based version of DBus1Config is used in a CMake project
122 (dbus#267, dbus!96; Clemens Lang)
124 dbus 1.12.12 (2018-12-04)
125 =========================
127 The “draconic disciple” release.
129 dbus version control is now hosted on freedesktop.org's Gitlab
130 installation, and bug reports and feature requests have switched from
131 Bugzilla bugs (indicated by "fd.o #nnn") to Gitlab issues ("dbus#nnn")
132 and merge requests ("dbus!nnn").
136 • Reference the freedesktop.org Code of Conduct (Simon McVittie)
140 • Stop the dbus-daemon leaking memory (an error message) if delivering
141 the message that triggered auto-activation is forbidden. This is
142 technically a denial of service because the dbus-daemon will
143 run out of memory eventually, but it's a very slow and noisy one,
144 because all the rejected messages are also very likely to have
145 been logged to the system log, and its scope is typically limited by
146 the finite number of activatable services available.
147 (dbus#234, Simon McVittie)
149 • Remove __attribute__((__malloc__)) attribute on dbus_realloc(),
150 which does not meet the criteria for that attribute in gcc 4.7+,
151 potentially leading to miscompilation (fd.o #107741, Simon McVittie)
153 • Fix some small O(1) memory leaks (fd.o #107320, Simon McVittie)
155 • Fix printf formats for pointer-sized integers on 64-bit Windows
156 (fd.o #105662, Ralf Habacker)
158 • Always use select()-based poll() emulation on Darwin-based OSs
159 (macOS, etc.) and on Interix, similar to what libcurl does
160 (dbus#232, dbus!19; Simon McVittie)
162 • Extend a test timeout to avoid spurious failures in CI
163 (dbus!26, Simon McVittie)
167 • Add Travis-CI builds for 64-bit Windows using mingw-w64
168 (fd.o #105662, Ralf Habacker)
170 • Add Gitlab-CI integration (fd.o #108177, Simon McVittie)
172 dbus 1.12.10 (2018-08-02)
173 =========================
175 The “beam deflection” release.
179 • Prevent reading up to 3 bytes beyond the end of a truncated message.
180 This could in principle be an information leak or denial of service
181 on the system bus, but is not believed to be exploitable to crash
182 the system bus or leak interesting information in practice.
183 (fd.o #107332, Simon McVittie)
185 • Fix build with gcc 8 -Werror=cast-function-type
186 (fd.o #107349, Simon McVittie)
188 • Fix warning from gcc 8 about suspicious use of strncpy() when
189 populating struct sockaddr_un (fd.o #107350, Simon McVittie)
191 • Fix a minor memory leak when a DBusServer listens on a new address
192 (fd.o #107194, Simon McVittie)
194 • Fix an invalid NULL argument to rmdir() if a nonce-tcp DBusServer
195 runs out of memory (fd.o #107194, Simon McVittie)
197 • Don't use misleading errno-derived error names if getaddrinfo() or
198 getnameinfo() fails with a code other than EAI_SYSTEM
199 (fd.o #106395, Simon McVittie)
201 • Skip tests that require working TCP if we are in a container environment
202 where 127.0.0.1 cannot be resolved (fd.o #106812, Simon McVittie)
204 dbus 1.12.8 (2018-04-30)
205 ========================
207 The “golden super-velociraptor” release.
211 • The Devhelp documentation index is now in version 2 format
212 (fd.o #106186, Simon McVittie)
214 • Give the dbus-daemon man page some scarier warnings about
215 <allow_anonymous/> and non-local TCP, which are insecure and should
216 not be used, particularly for the standard system and session buses
217 (fd.o #106004, Simon McVittie)
221 • Fix installation of Ducktype documentation with newer yelp-build
222 versions (fd.o #106171, Simon McVittie)
224 dbus 1.12.6 (2018-03-01)
225 ========================
227 The “just the one swan, actually” release.
231 • Increase system dbus-daemon's RLIMIT_NOFILE rlimit before it drops
232 privileges, because it won't have permission afterwards. This fixes a
233 regression in dbus 1.10.18 and 1.11.0 which made the standard system bus
234 more susceptible to deliberate or accidental denial of service.
235 (fd.o #105165, David King)
237 dbus 1.12.4 (2018-02-08)
238 ========================
240 The “Stria Campania 115” release.
244 • When iterating the DBusConnection while blocking on a pending call,
245 don't wait for I/O if that pending call already has a result; and make
246 sure that whether it has a result is propagated in a thread-safe way.
247 This prevents certain multi-threaded calling patterns from blocking
248 until their timeout even when they should have succeeded sooner.
249 (fd.o #102839; Manish Narang, Michael Searle)
251 • Report the correct error if OOM is reached while trying to listen
252 on a TCP socket (fd.o #89104, Simon McVittie)
254 • Fix assertion failures in recovery from OOM while setting up a
255 DBusServer (fd.o #89104, Simon McVittie)
257 • Add a missing space to a warning message (fd.o #103729, Thomas Zajic)
259 • Expand ${bindir} correctly when pkg-config is asked for dbus_daemondir
260 (fd.o #104265, Benedikt Heine)
262 • On Linux systems with systemd < 237, if ${localstatedir}/dbus doesn't
263 exist, create it before trying to create ${localstatedir}/dbus/machine-id
264 (fd.o #104577, Chris Lesiak)
266 • Fix escaping in dbus-api-design document (fd.o #104925, Philip Withnall)
268 dbus 1.12.2 (2017-11-13)
269 ========================
271 The “spider pumpkin” release.
275 • Log a warning if a new connection cannot be accepted due to an
276 out-of-memory condition or failure to identify its AppArmor or
277 SELinux context (fd.o #103592, Simon McVittie)
281 • Make use of $(MKDIR_P) compatible with install-sh, fixing build when a
282 GNU-compatible `mkdir -p` is not available (fd.o #103521, ilovezfs)
284 • When building for Windows with Autotools, avoid `echo -e`, fixing
285 cross-compilation on non-GNU platforms like macOS
286 (fd.o #103493, Tony Theodore)
288 • Fix crashes in the server side of the nonce-tcp: transport under
289 various error conditions. This transport should normally only be used
290 on Windows, where AF_UNIX sockets are unavailable; the unix: transport
291 is the only one recommended for production use on Unix platforms.
292 (fd.o #103597, Simon McVittie)
296 • Improve test coverage on Travis-CI (Simon McVittie)
298 dbus 1.12.0 (2017-10-30)
299 ========================
301 The “gingerbread skull” release.
303 1.12.x is a new stable branch, recommended for use in OS
306 Summary of major changes between 1.10.x and 1.12.0
307 --------------------------------------------------
311 • Expat >= 2.1.0 is required.
312 • GLib >= 2.40 is required if full test coverage is enabled.
313 • [Linux] libselinux >= 2.0.86 is required if SELinux support is
315 • [Unix] dbus now requires an <inttypes.h> that defines C99 constants
316 such as PRId64 and PRIu64, except when building for Windows.
317 • [Autotools] Building from git (but not from tarballs) with Autotools
318 now requires macros from the GNU Autoconf Archive.
319 • [CMake] Builds done using CMake now require CMake 3.0.2.
321 Build-time configuration changes:
323 • Expat is now found using pkg-config. See the release notes for
325 • The --disable-compiler-optimisations and --enable-compiler-coverage
326 options no longer exist. See the release notes for 1.11.4 and 1.11.8.
327 • [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
328 options no longer exist. See the release notes for 1.11.20.
329 • [Unix] Flag files in /var/run/console/${username} are no longer
330 checked for at_console by default. See the release notes for 1.11.18.
331 • [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
332 and packagers will now need to add these downstream (most already do).
333 See the release notes for 1.11.18.
334 • [Unix] The process ID file no longer has a different default location
335 on Red Hat derivatives. See the release notes for 1.11.18.
336 • [Unix] ${runstatedir} is now independent of ${localstatedir} with
337 recent Autotools versions. See the release notes for 1.11.16.
338 • [Windows] The WINDRES variable is no longer used. See the release
343 • Eavesdropping is officially deprecated in favour of BecomeMonitor.
344 See the release notes for spec version 0.31 (in dbus 1.11.14).
345 • [Unix] Flag files in /var/run/console/${username} are deprecated.
346 See the release notes for 1.11.18.
350 • <allow> and <deny> rules in dbus-daemon configuration can now
351 include send_broadcast="true", send_broadcast="false",
352 max_unix_fds="N", min_unix_fds="N" (for some integer N).
353 See the release notes for 1.11.18.
354 • dbus_try_get_local_machine_id() is like
355 dbus_get_local_machine_id(), but returns a DBusError.
356 • New APIs around DBusMessageIter to simplify cleanup.
357 See the release notes for 1.11.16.
358 • The message bus daemon now implements the standard Introspectable,
359 Peer and Properties interfaces. See the release notes for
360 dbus 1.11.14 and spec version 0.31.
361 • DTDs for introspection XML and bus configuration are installed.
362 • dbus can be compiled to be relocatable, making it more suitable for
363 binary bundling with other software. On Windows, this is on by
365 • [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
366 never uses Linux abstract sockets, which is advantageous for
367 containers. On non-Linux it is equivalent to unix:tmpdir=….
368 See the release notes for dbus 1.11.14 and spec version 0.31.
369 • [Unix] New option "dbus-launch --exit-with-x11".
370 • [Unix] Session managers can create transient .service files in
371 $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
372 • [Unix] A sysusers.d snippet can create the messagebus user on-demand.
374 Miscellaneous behaviour changes:
376 • [Unix] The session bus now logs to syslog if it was started by
378 • [Unix] Internal warnings are logged to syslog if configured.
379 • [Unix] Exceeding an anti-DoS limit is logged to syslog if configured,
382 Changes since 1.11.22 release candidate
383 ---------------------------------------
385 Standard stable-branch changes:
387 • Disable warnings about use of deprecated functions (Simon McVittie)
391 • Don't distribute files generated by ./configure in the source tarball
392 (fd.o #103420, Simon McVittie)
396 • Remove some unused files from the git repository
397 (fd.o #103420, Simon McVittie)
399 D-Bus 1.11.22 (2017-10-23)
400 ==========================
402 The “fire surface” release.
404 This is the first release-candidate for the 1.12.0 stable release.
406 Build-time configuration changes:
408 • When building for Windows with Autotools, setting the WINDRES variable
409 no longer works to select a non-standard resource compiler. Use
410 libtool's standard RC variable instead, for example
411 "./configure RC=i686-w64-mingw32-windres"
415 • Builds done using CMake now require CMake 3.0.2.
419 • When building for Windows, improve quality of metadata in
420 libdbus-1-3.dll (fd.o #103015, Ralf Habacker)
424 • Fix a typo "uint 16" in dbus-send(1) man page
425 (fd.o #103075, David King)
427 • When building for Windows, libdbus-1-3.dll always includes version
428 information. Previously, this was missing if using CMake and any
429 non-MSVC compiler. (fd.o #103015, Ralf Habacker)
431 • Fix the build with MSVC, which regressed with the #102558 fix in
432 1.11.20. (fd.o #102558, Ralf Habacker)
436 • Simplify Windows resource embedding
437 (fd.o #103015, Simon McVittie)
439 D-Bus 1.11.20 (2017-10-03)
442 The “wraith stun” release.
444 Build-time configuration changes:
446 • The --enable-abstract-sockets and --disable-abstract-sockets options
447 no longer exist. Support for Linux's abstract AF_UNIX sockets is now
448 unconditionally enabled on Linux and disabled everywhere else.
449 (fd.o #34905, Simon McVittie)
453 • Make slower tests less likely to time out, and improve diagnostics if
454 tests do time out (fd.o #103009, Simon McVittie)
456 • On Windows, don't compile an unused stub implementation of
457 _dbus_set_signal_handler() (fd.o #103010, Simon McVittie)
461 • Be more careful to save and restore errno in POSIX async signal
462 handlers (fd.o #103010, Simon McVittie)
464 • On Windows, embed a manifest in dbus-update-activation-environment.exe
465 so that the heuristics used for UAC do not assume it needs elevated
466 privileges due to its name containing "update"
467 (fd.o #102558, Ralf Habacker)
469 • On Windows with Automake, embed version information in libdbus-1,
470 as was meant to happen in all versions since 2009
471 (fd.o #103015, Simon McVittie)
473 D-Bus 1.11.18 (2017-09-25)
476 The “vampire conquistador” release.
478 Build-time configuration changes:
480 • By default, dbus-daemon on Unix no longer checks for flag files
481 /var/run/console/${username} created by the obsolete pam_console and
482 pam_foreground PAM modules when deciding whether ${username} is
483 currently at the console. The old default behaviour can be restored
484 by specifying --with-console-auth-dir=/var/run/console in the
485 recommended Autotools build system, or
486 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
487 now deprecated, and will be removed in dbus 1.13 unless feedback via
488 fd.o #101629 indicates that this would be problematic.
489 (fd.o #101629, Simon McVittie)
491 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
492 script for Cygwin, are no longer provided in the upstream dbus
493 source. We recommend that distributors who support non-systemd service
494 management should maintain their own init scripts or other service
495 manager integration as part of their downstream packaging, similar to
496 the way Debian distributes a Debian-specific LSB init script for dbus.
498 The systemd unit continues to be maintained as part of the upstream
499 dbus source, because it receives regular testing and maintenance.
501 (fd.o #101706, Simon McVittie)
503 • The process ID file created by the system bus is no longer influenced
504 by the --with-init-scripts=redhat configure option or the presence of
505 /etc/redhat-release at build time. If your OS's init script or other
506 service management relies on the Red Hat-style pid file, it can be
507 restored by specifying --with-system-pid-file=/run/messagebus.pid at
508 configure time or using the <pidfile> directive in bus configuration.
510 Note that the upstream-supplied systemd unit runs dbus-daemon with
511 the --nopidfile option, so it does not normally write a pid file,
512 regardless of whether the OS is Red-Hat-derived or not.
514 (fd.o #101706, Simon McVittie)
518 • <allow> and <deny> rules in dbus-daemon configuration can now
519 include send_broadcast="true" or send_broadcast="false", which make
520 the rule only match broadcast signals, or only match messages that
521 are not broadcast signals, respectively.
522 (fd.o #29853, Simon McVittie)
524 • <allow> and <deny> rules can now be configured to apply only to
525 messages with or without Unix file descriptors attached. This would
526 typically be used in rules like these:
527 <allow send_destination="..." max_unix_fds="0"/>
528 <deny send_destination="..." min_unix_fds="1"/>
529 <deny receive_sender="..." min_unix_fds="1"/>
530 but can also be used to set a nonzero upper limit on the number of
532 <allow send_destination="..." max_unix_fds="4"/>
533 (fd.o #101848, Simon McVittie)
535 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
536 now respects the HOME environment variable on the client side, and
537 on the server side when the uid attempting to connect is the same
538 as the uid of the server. This allows the automated tests to pass in
539 environments where the user's "official" home directory in /etc/passwd
540 is nonexistent, such as Debian autobuilders.
541 (fd.o #101960, Simon McVittie)
545 • When parsing dbus-daemon configuration, tell Expat not to use
546 cryptographic-quality entropy as a salt for its hash tables: we trust
547 the configuration files, so we are not concerned about algorithmic
548 complexity attacks via hash table collisions. This prevents
549 dbus-daemon --system from holding up the boot process (and causing
550 early-boot system services like systemd, logind, networkd to time
551 out) on entropy-starved embedded systems.
552 (fd.o #101858, Simon McVittie)
554 • Avoid a -Werror=declaration-after-statement build failure on Solaris
555 (fd.o #102145, Alan Coopersmith)
557 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
558 to LOG_INFO, matching how we use this log level in practice
559 (fd.o #102686, Simon McVittie)
561 D-Bus 1.11.16 (2017-07-27)
564 The “south facing garden” release.
566 Build-time configuration changes:
568 • The Autotools build system now supports varying ${runstatedir}
569 independently of ${localstatedir}, if using an Autoconf version
570 that has that feature; version 2.70 will eventually have this, but
571 many Linux distributions add it to version 2.69 as a patch.
572 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
573 and runstatedir=/run. (fd.o #101569, Simon McVittie)
577 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
578 and dbus_message_iter_abandon_container_if_open() simplify the
579 single-exit-point ("goto out") style of resource cleanup. The API
580 documentation around DBusMessageIter and containers has also been
581 clarified. (fd.o #101568, Simon McVittie)
585 • Fix the implementation of re-enabling a timeout (again) so that its
586 countdown is always restarted as intended. (fd.o #95619,
589 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
590 available to all users on the system bus (fd.o #101700, Simon McVittie)
592 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
593 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
595 • dbus_message_iter_open_container() no longer leaks memory if it runs out
596 of memory. (fd.o #101568, Simon McVittie)
598 • dbus_message_append_args_valist() no longer leaks memory if given an
599 unsupported type. This situation is still considered to be a programming
600 error which needs to be corrected by the user of libdbus.
601 (fd.o #101568, Simon McVittie)
603 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
604 will no longer report that their arguments were invalid if they run out
605 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
607 • Ensure that tests fail if they would otherwise have tried to connect to
608 the real session bus (fd.o #101698, Simon McVittie)
610 • Make build-time tests cope with finding Python 3, but not Python 2
611 (fd.o #101716, Simon McVittie)
613 Internal changes relevant to dbus developers:
615 • DBusVariant is a new mechanism to copy single values from a message into
616 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
618 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
619 Logging an ERROR message does not make the process exit; the caller
620 is responsible for calling abort() or exit(), whichever is more appropriate.
621 (fd.o #101568, Simon McVittie)
623 • Better test coverage (fd.o #101568, Simon McVittie)
625 D-Bus 1.11.14 (2017-06-29)
628 The “irrational fear of bees” release.
632 • Expat >= 2.1.0 is always required
633 • libselinux >= 2.0.86 is required if SELinux support is enabled
634 • GLib >= 2.40 is required if full test coverage is enabled
636 Build-time configuration changes:
638 • We now use pkg-config to find libexpat in Autotools builds. This requires
639 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
640 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
641 itself cause compilation failures.
643 As with all pkg-config-based configure checks, you can use
644 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
645 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
646 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
649 (fd.o #69801, Simon McVittie)
651 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
652 is required due to the removal of explicit refcounting for SIDs.
653 (fd.o #100912, Laurent Bigonville)
657 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
658 as a side-effect of a sufficiently privileged process merely reading the
659 machine ID. It is no longer copied as a side-effect of reading.
660 Running dbus-uuidgen --ensure, which should be done after installing dbus,
661 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
662 former exists and the latter does not.
663 (fd.o #101257, Simon McVittie)
665 • The undocumented Verbose interface, and the GetAllMatchRules method on
666 the undocumented Stats interface, must now be used via the object path
667 /org/freedesktop/DBus. Previously, they existed on all object paths.
668 (fd.o #101257, Simon McVittie)
670 • AddMatch() with a match rule containing eavesdrop='true' will now fail
671 unless called by either the same user as the dbus-daemon, or Unix uid 0
672 (root), matching the restrictions applied to the newer BecomeMonitor()
673 method. On the session bus this has no practical effect. On the system
674 bus this will prevent certain configurations that already did not
675 work well in practice. (fd.o #101567, Simon McVittie)
679 • D-Bus Specification version 0.31
680 · Don't require implementation-specific search paths to be lowest
682 · Correct regex syntax for optionally-escaped bytes in addresses so it
683 includes hyphen-minus, forward slash and underscore as intended
684 · Describe all message bus methods in the same section
685 · Clarify the correct object path for method calls to the message bus
686 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
687 · Document that the message bus implements Introspectable, Peer and
689 · Add new Features and Interfaces properties for message bus
691 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
693 · Don't require eavesdrop='true' to be accepted from connections not
694 sufficiently privileged to use it successfully
695 · Formally deprecate eavesdropping in favour of BecomeMonitor
696 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
697 Simon McVittie, Tom Gundersen)
699 • Implement the Properties and Peer interfaces in dbus-daemon
700 (fd.o #101257, Simon McVittie)
702 • New function dbus_try_get_local_machine_id() is like
703 dbus_get_local_machine_id(), but returning a DBusError. Other code
704 that needs the machine ID will now report a recoverable error (instead
705 of logging to stderr and aborting) if no machine ID is available.
706 Generating a machine ID is still considered to be a required part of
707 installing dbus correctly. (fd.o #13194, Simon McVittie)
709 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
710 (fd.o #101315, Laurent Bigonville)
712 • Avoid deprecated API calls when using SELinux
713 (fd.o #100912, Laurent Bigonville)
715 • Switch a test from the deprecated g_test_trap_fork() to
716 g_test_trap_subprocess(), for Windows support and better robustness
717 on Unix (fd.o #101362, Simon McVittie)
719 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
720 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
721 This prevents the two files from going out of sync on stateless or live
722 images without needing to run dbus-uuidgen, and supports older D-Bus
723 implementations that do not necessarily read /etc/machine-id themselves.
724 (fd.o #101570, Simon McVittie)
726 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
727 abstract sockets. This is preferable when used with Linux containers.
728 (fd.o #101567, Simon McVittie)
732 • Fix a reference leak when blocking on a pending call on a connection
733 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
735 • Don't put timestamps in the Doxygen-generated documentation,
736 or hard-code the build directory into builds with embedded tests,
737 for reproducible builds (fd.o #100692, Simon McVittie)
739 • Fix some integration test issues (fd.o #100686, Simon McVittie)
741 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
743 • If we somehow get an autolaunch address with multiple semicolon-separated
744 components, and they don't work, don't invalidly "pile up" errors
745 (fd.o #101257, Simon McVittie)
749 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
750 (fd.o #100715, Simon McVittie)
752 D-Bus 1.11.12 (2017-04-07)
755 The “it's something humans do” release.
759 • The session dbus-daemon now supports transient .service files
760 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
761 service directories, this directory is not monitored with inotify
762 or similar, and the service files must be named exactly
763 ${bus_name}.service. (fd.o #99825, Simon McVittie)
765 • dbus can be configured with --enable-relocation when building with
766 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
767 to make the pkg-config metadata relocatable. This is useful for
768 non-standard prefixes, and in particular for Windows installations.
769 However, it is not recommended for system-wide installations into
770 /usr, because it interferes with pkg-config's ability to filter out
771 compiler default linker directories.
773 With Autotools, the default is --enable-relocation when building
774 for Windows or --disable-relocation otherwise. With CMake, the default
775 is -DDBUS_RELOCATABLE=ON.
777 (fd.o #99721; Ralf Habacker, Simon McVittie)
779 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
780 own FindDBus.cmake macros, whether dbus was compiled with Autotools
781 or with CMake. See the end of README.cmake for more information.
782 (fd.o #99721; Ralf Habacker, Simon McVittie)
786 • Always read service file directories in the intended order
787 (fd.o #99825, Simon McVittie)
789 • When tests are skipped, don't try to kill nonexistent process 0
790 (fd.o #99825, Simon McVittie)
792 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
794 • Fix a harmless read overflow and some memory leaks in a unit test
795 (fd.o #100568, Philip Withnall)
797 • Fix some typos in test code
798 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
800 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
801 in documentation (fd.o #99901, Philip Withnall)
803 • Fix and enable compiler warnings related to -Wswitch
804 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
806 • Fix writing off the end of a fd_set when testing with valgrind
807 (fd.o #99839, Philip Withnall)
809 D-Bus 1.11.10 (2017-02-16)
812 The “purple hair gives you telekinesis?” release.
816 • AppArmor support requires at least libapparmor 2.8.95, reduced
817 from 2.10 in previous versions. One test requires 2.10 and is
818 skipped if building with an older version.
822 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
823 stable and Debian testing in addition to the older Ubuntu that is
824 the default (fd.o #98889, Simon McVittie)
826 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
828 • Silence many -Wswitch-enum and -Wswitch-default warnings
829 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
831 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
832 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
834 • Install pkg-config metadata on Unix even if building with CMake
835 (fd.o #99752, Ralf Habacker)
837 • Exclude auth mechanisms from REJECTED message if they are supported
838 in the code but but configured to be disallowed (fd.o #99621,
843 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
844 allow an attacker to overwrite a file named "nonce", in a directory
845 that the user running dbus-daemon can write, with a random value
846 known only to the user running dbus-daemon. This is unlikely to be
847 exploitable in practice, particularly since the nonce-tcp transport
848 is really only useful on Windows.
850 On Unix systems we strongly recommend using only the unix: and systemd:
851 transports, together with EXTERNAL authentication. These are the only
852 transports and authentication mechanisms enabled by default.
854 (fd.o #99828, Simon McVittie)
856 • Avoid symlink attacks in the "embedded tests", which are not enabled
857 by default and should never be enabled in production builds of dbus.
858 (fd.o #99828, Simon McVittie)
860 • Fix the implementation of re-enabling a timeout so that its
861 countdown is restarted as intended, instead of continually
862 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
864 • When receiving a message with file descriptors, do not start reading
865 the beginning of the next message, so that only one such message
866 is processed at a time. In conjunction with the fix for #95619
867 this means that processes sending many file descriptors, such as
868 systemd-logind on a system that receives very rapid ssh connections,
869 are not treated as abusive and kicked off the bus. Revert the previous
870 workaround that special-cased uid 0.
871 (fd.o #95263, LP#1591411; Simon McVittie)
873 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
874 for Windows with CMake (fd.o #99586, Ralf Habacker)
876 • Do not set Unix-specific variables when targeting Windows
877 (fd.o #99586, Ralf Habacker)
879 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
880 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
882 • Use relative install locations in CMake on Unix to respect DESTDIR,
883 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
885 • Install dbus-arch-deps.h correctly when using CMake
886 (fd.o #99586, #99721; Ralf Habacker)
888 • Improve argument validation for `dbus-test-tool spam`
889 (ffd.o #99693, Coverity #54759; Philip Withnall)
891 • Don't shift by a negative integer if a hash table becomes monstrously
892 large (fd.o #99641, Coverity #54682; Philip Withnall)
894 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
895 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
897 • Remove an unnecessary NULL check
898 (fd.o #99642, Coverity #141062; Philip Withnall)
900 • Improve error handling in unit tests and dbus-send
901 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
902 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,
903 #54710, #54711, #54714, #54715, #54718, #54721, #54724, #54726,
904 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
906 • Do not print verbose messages' timestamps to stderr if the actual message
907 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
909 D-Bus 1.11.8 (2016-11-28)
912 The “panics in the face of breakfast foods” release.
914 Build-time configuration:
916 • The new --enable-debug configure option provides an easy way to
917 enable debug symbols, disable optimization and/or enable profiling.
919 • The --enable-compile-warnings configure option can be used to control
922 • The --disable-compiler-optimisations configure option is no longer
923 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
927 • D-Bus Specification version 0.30
928 · Define the jargon term "activation" more clearly
929 · Define the jargon term "auto-starting", which is one form of activation
930 · Document the optional SystemdService key in service files
931 · Use versioned interface and bus names in most examples
932 · Clarify intended behaviour of Properties.GetAll
933 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
935 • Fix and enable a lot of compiler warnings to improve future code
936 quality. This might incidentally also fix some environment variable
938 · In particular, printf-style functions in the libdbus API are now annotated
939 with __attribute__((__format__(__printf__, *, *))) when compiling with
940 gcc or clang. This might make printf bugs in other software visible
942 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
943 Thomas Zimmermann, Simon McVittie)
945 • When running with AppArmor mediation (for example using Ubuntu's patched
946 Linux kernel), clients can no longer auto-start services unless they would
947 have been able to send the auto-starting message to the service after it
948 starts. StartServiceByName() is unaffected, and continues to be allowed by
949 default in AppArmor's <abstractions/dbus-strict> and
950 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
954 • Work around an undesired effect of the fix for CVE-2014-3637
955 (fd.o #80559), in which processes that frequently send fds, such as
956 logind during a flood of new PAM sessions, can get disconnected for
957 continuously having at least one fd "in flight" for too long;
958 dbus-daemon interprets that as a potential denial of service attack.
959 The workaround is to disable that check for uid 0 process such as
960 logind, with a message in the system log. The bug remains open while
961 we look for a more general solution.
962 (fd.o #95263, LP#1591411; Simon McVittie)
964 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
965 was disabled at compile time. That test is not expected to work
966 in that configuration. (fd.o #98665, Simon McVittie)
968 D-Bus 1.11.6 (2016-10-10)
971 The “darkly whimsical” release.
975 • Do not treat ActivationFailure message received from root-owned systemd
976 name as a format string. In principle this is a security vulnerability,
977 but we do not believe it is exploitable in practice, because only
978 privileged processes can own the org.freedesktop.systemd1 bus name, and
979 systemd does not appear to send activation failures that contain "%".
981 Please note that this probably *was* exploitable in dbus versions
982 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
983 the time was only thought to be a denial of service vulnerability
984 (CVE-2015-0245). If you are still running one of those versions,
985 patch or upgrade immediately.
987 (fd.o #98157, Simon McVittie)
991 • D-Bus Specification version 0.29
992 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
993 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
995 • Log to syslog when we exceed various anti-DoS limits, and add test
996 coverage for them (fd.o #86442, Simon McVittie)
998 • Improve syslog handling so that _dbus_warn() and similar warnings
999 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
1000 and log to syslog (instead of /dev/null) when dbus-daemon is started by
1001 dbus-launch. (fd.o #97009, Simon McVittie)
1003 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
1004 (fd.o #89011, Philip Withnall)
1006 • When logging messages about service activation, mention which peer
1007 requested the activation (fd.o #68212, Philip Withnall)
1009 • On Linux, mention the LSM label (if available) whenever we print
1010 debug information about a peer (fd.o #68212, Philip Withnall)
1014 • Harden dbus-daemon against malicious or incorrect ActivationFailure
1015 messages by rejecting them if they do not come from a privileged
1016 process, or if systemd activation is not enabled
1017 (fd.o #98157, Simon McVittie)
1019 • Avoid undefined behaviour when setting reply serial number without going
1020 via union DBusBasicValue (fd.o #98035, Marc Mutz)
1022 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
1023 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
1025 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
1027 D-Bus 1.11.4 (2016-08-15)
1030 The “copper pickaxe” release.
1034 • Building from git (but not from tarballs) now requires
1035 macros from the GNU Autoconf Archive, for example the autoconf-archive
1036 package in Debian or Fedora derivatives.
1038 Build-time configuration:
1040 • The option to enable coverage instrumentation has changed from
1041 --enable-compiler-coverage to --enable-code-coverage.
1045 • D-Bus Specification version 0.28
1046 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
1048 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
1049 minimizing failed connections under heavy load
1050 (fd.o #95264, Lennart Poettering)
1052 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
1054 • Use the same regression tests for subprocess starting on Unix and Windows
1055 (fd.o #95191, Ralf Habacker)
1057 • Print timestamps and thread IDs in verbose messages
1058 (fd.o #95191, Ralf Habacker)
1060 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
1061 pointing to /dev/null (fd.o #97008, Simon McVittie)
1063 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
1064 (fd.o #88922, Thomas Zimmermann)
1068 • On Windows, fix a memory leak in replacing the installation prefix
1069 (fd.o #95191, Ralf Habacker)
1071 • On Linux, when dbus-daemon is run with reduced susceptibility to the
1072 OOM killer (typically via systemd), do not let child processes inherit
1073 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
1075 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
1076 even if a parent process incorrectly starts them with stdin, stdout
1077 and/or stderr closed (fd.o #97008, Simon McVittie)
1079 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
1080 contains a semicolon (fd.o #94746, Thiago Macieira)
1082 • Fix memory leaks and thread safety in subprocess starting on Windows
1083 (fd.o #95191, Ralf Habacker)
1085 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
1086 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
1088 • In tests that exercise correct handling of crashing D-Bus services,
1089 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
1091 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
1093 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
1094 in some test cases (fd.o #93909, Nick Lewycky)
1096 • Add assertions to reassure a static analysis tool
1097 (fd.o #93210, Deepika Aggarwal)
1099 • Be explicit about enum comparison when loading XML
1100 (fd.o #93205, Deepika Aggarwal)
1102 • update-activation-environment: produce better diagnostics on error
1103 (fd.o #96653, Simon McVittie)
1105 • Avoid various compiler warnings with gcc 6
1106 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
1108 • On Unix when configured to use the system log, report as "dbus-daemon",
1109 not as "dbus" (fd.o #97009, Simon McVittie)
1111 • During unit tests, reduce the amount we write to the system log
1112 (fd.o #97009, Simon McVittie)
1114 D-Bus 1.11.2 (2016-03-07)
1117 The “pneumatic drill vs. Iron Maiden” release.
1121 • Enable "large file support" on systems where it exists: dbus-daemon
1122 is not expected to open large files, but it might need to stat files
1123 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
1125 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
1126 which might result in a pedantic C compiler not copying the entire contents
1127 of a DBusMessageIter; statically assert that this is not an ABI change
1128 in practice (fd.o #94136, Simon McVittie)
1130 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
1131 (fd.o #94244, Dmitri Iouchtchenko)
1133 • Correctly report test failures in C tests from run-test.sh
1134 (fd.o #93379; amit tewari, Simon McVittie)
1136 • When tests are enabled, run all the marshal-validate tests, not just
1137 the even-numbered ones (fd.o #93908, Nick Lewycky)
1139 • Correct the expected error from one marshal-validate test, which was
1140 previously not run due to the above bug (fd.o #93908, Simon McVittie)
1142 • Fix compilation under CMake when embedded tests are disabled
1143 (fd.o #94094, eric.hyer)
1147 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
1148 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
1150 • When building with CMake, use the same gcc/clang warnings as under Autotools,
1151 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
1153 • test/name-test: make C tests produce TAP output and run them directly, not
1154 via run-test.sh (fd.o #92899, Simon McVittie)
1156 • Under CMake when cross-compiling for Windows on Unix, run the tests
1157 under Wine even if binfmt_misc support is not available
1158 (fd.o #88966, Ralf Habacker)
1160 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
1161 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
1163 • Factor out some functions that will be needed in future for a Windows
1164 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
1166 D-Bus 1.11.0 (2015-12-02)
1169 The “peppermint deer” release.
1173 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
1174 C99 constants such as PRId64 and PRIu64.
1178 • D-Bus Specification version 0.27
1179 · Specify that services should not reply if NO_REPLY_EXPECTED was used
1180 (fd.o #75749, Lars Uebernickel)
1182 • Add a script to do continuous-integration builds, and metadata to run it
1183 on travis-ci.org. To use this, clone the dbus git repository on GitHub
1184 and set it up with travis-ci.org; the only special setting needed is
1185 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
1187 • If dbus-daemon is run with --systemd-activation, do not require
1188 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
1192 • Re-order dbus-daemon startup so that on SELinux systems, the thread
1193 that reads AVC notifications retains the ability to write to the
1194 audit log (fd.o #92832, Laurent Bigonville)
1196 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
1198 • When using the Monitoring interface, match messages' destinations
1199 (fd.o #92074, Simon McVittie)
1201 • On Linux with systemd, stop installing a reference to the obsolete
1202 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
1205 • On Windows, when including configuration files with <include> or
1206 <includedir>, apply the same relocation as for the Exec paths
1207 in .service files (fd.o #92028, Simon McVittie)
1209 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
1211 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
1213 D-Bus 1.10.6 (2015-12-01)
1216 The “marzipan beetles” release.
1220 • On Unix when running tests as root, don't assert that root and
1221 the dbus-daemon user can still call UpdateActivationEnvironment;
1222 assert that those privileged users can call BecomeMonitor instead
1223 (fd.o #93036, Simon McVittie)
1225 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
1228 • On Windows Autotools builds, don't run tests that rely on
1229 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
1231 D-Bus 1.10.4 (2015-11-17)
1234 The “Frostburn Canyon” release.
1238 • GetConnectionCredentials, GetConnectionUnixUser and
1239 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
1240 will now return details of the dbus-daemon itself. This is required
1241 to be able to call SetEnvironment on systemd.
1242 (fd.o #92857, Jan Alexander Steffens)
1246 • Make UpdateActivationEnvironment always fail with AccessDenied on the
1247 system bus. Previously, it was possible to configure it so root could
1248 call it, but the environment variables were not actually used,
1249 because the launch helper would discard them.
1250 (fd.o #92857, Jan Alexander Steffens)
1252 • On Unix with --systemd-activation on a user bus, make
1253 UpdateActivationEnvironment pass on its arguments to systemd's
1254 SetEnvironment method, solving inconsistency between the environments
1255 used for traditional activation and systemd user-service activation.
1256 (fd.o #92857, Jan Alexander Steffens)
1258 • On Windows, don't crash if <syslog/> or --syslog is used
1259 (fd.o #92538, Ralf Habacker)
1261 • On Windows, fix a memory leak when setting a DBusError from a Windows
1262 error (fd.o #92721, Ralf Habacker)
1264 • On Windows, don't go into infinite recursion if we abort the process
1265 with backtraces enabled (fd.o #92721, Ralf Habacker)
1267 • Fix various failing tests, variously on Windows and cross-platform:
1268 · don't test system.conf features (users, groups) that only make sense
1269 on the system bus, which is not supported on Windows
1270 · don't call _dbus_warn() when we skip a test, since it is fatal
1271 · fix computation of expected <standard_session_servicedirs/>
1272 · when running TAP tests, translate newlines to Unix format, fixing
1273 cross-compiled tests under Wine on Linux
1274 · don't stress-test refcounting under Wine, where it's really slow
1275 · stop assuming that a message looped-back to the test will be received
1277 · skip some system bus tests on Windows since they make no sense there
1278 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
1280 D-Bus 1.10.2 (2015-10-26)
1283 The “worst pies in London” release.
1287 • Correct error handling for activation: if there are multiple attempts
1288 to activate the same service and it fails immediately, the first attempt
1289 would get the correct reply, but the rest would time out. We now send
1290 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
1292 • If BecomeMonitor is called with a syntactically invalid match rule,
1293 don't crash with an assertion failure, fixing a regression in 1.9.10.
1294 This was not exploitable as a denial of service, because the check
1295 for a privileged user is done first. (fd.o #92298, Simon McVittie)
1297 • On Linux with --enable-user-session, add the bus address to the
1298 environment of systemd services for better backwards compatibility
1299 (fd.o #92612, Jan Alexander Steffens)
1301 • On Windows, fix the logic for replacing the installation prefix
1302 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
1304 • On Windows, if installed in the conventional layout with ${prefix}/etc
1305 and ${prefix}/share, use relative paths between bus configuration files
1306 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
1308 • Make more of the regression tests pass in Windows builds (fd.o #92538,
1311 D-Bus 1.10.0 (2015-08-25)
1316 This is a new stable branch, recommended for use in OS distributions.
1320 • distribute test/tap-test.sh.in, even if the tarball was built without
1321 tests enabled (fd.o #91684, Simon McVittie)
1322 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
1324 Summary of major changes since 1.8.0:
1326 • The basic setup for the well-known system and session buses is
1327 now done in read-only files in ${datadir} (normally /usr/share).
1328 See the NEWS entry for 1.9.18 for details.
1330 • AppArmor integration has been merged, with features similar to the
1331 pre-existing SELinux integration. It is mostly compatible with the
1332 patches previously shipped by Ubuntu, with one significant change:
1333 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
1334 by GetConnectionCredentials and was not included.
1336 • The --enable-user-session configure option can be enabled
1337 by OS integrators intending to use systemd to provide a session bus
1338 per user (in effect, treating all concurrent graphical and non-graphical
1339 login sessions as one large session).
1341 • The new listenable address mode "unix:runtime=yes" listens on
1342 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
1343 user session. libdbus and "dbus-launch --autolaunch" will connect to
1344 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
1347 • All executables are now dynamically linked to libdbus-1.
1348 Previously, some executables, most notably dbus-daemon, were statically
1349 linked to a specially-compiled variant of libdbus. This results in
1350 various private functions in the _dbus namespace being exposed by the
1351 shared library. These are not API, and must not be used outside
1352 the dbus source tree.
1354 • On platforms with ELF symbol versioning, all public symbols
1355 are versioned LIBDBUS_1_3.
1359 • org.freedesktop.DBus.GetConnectionCredentials returns
1360 LinuxSecurityLabel where supported
1361 • org.freedesktop.DBus.Monitoring interface (privileged)
1362 · BecomeMonitor method supersedes match rules with eavesdrop=true,
1363 which are now deprecated
1364 • org.freedesktop.DBus.Stats interface (semi-privileged)
1365 · now enabled by default
1366 · new GetAllMatchRules method
1367 • org.freedesktop.DBus.Verbose interface (not normally compiled)
1368 · toggles the effect of DBUS_VERBOSE
1373 • dbus-update-activation-environment
1375 New optional dependencies:
1377 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
1378 • Complete documentation requires Ducktype and yelp-tools
1379 • Full test coverage requires GLib 2.36 and PyGI
1380 • AppArmor integration requires libapparmor and optionally libaudit
1382 Dependencies removed:
1386 D-Bus 1.9.20 (2015-08-06)
1389 The “Remember Tomorrow” release.
1391 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
1396 • Don't second-guess what the ABI of poll() is, allowing it to be used
1397 on Integrity RTOS and other unusual platforms (fd.o #90314;
1398 Rolland Dudemaine, Simon McVittie)
1400 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
1401 both enabled (fd.o #89225, Simon McVittie)
1403 • Log audit events for AppArmor/SELinux policy violations whenever
1404 we have CAP_AUDIT_WRITE, even if not the system bus
1405 (fd.o #83856, Laurent Bigonville)
1407 D-Bus 1.9.18 (2015-07-21)
1410 The “Pirate Elite” release.
1412 Configuration changes:
1414 • The basic setup for the well-known system and session buses is now done
1415 in read-only files in ${datadir}, moving a step closer to systems
1416 that can operate with an empty /etc directory. In increasing order
1419 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
1420 the default message policies.
1421 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
1422 dbus still installs a trivial version of each, for documentation
1423 purposes; putting configuration directives in these files is deprecated.
1424 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
1425 to install "drop-in" configuration snippets (any packages
1426 using those directories should explicitly depend on at least this
1428 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
1429 or third-party software to install "drop-in" configuration snippets
1430 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
1433 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
1434 and "s*" refers to either system or session as appropriate.
1436 (fd.o #89280, Dimitri John Ledkov)
1440 • Fix a memory leak when GetConnectionCredentials() succeeds
1441 (fd.o #91008, Jacek Bukarewicz)
1443 • Ensure that dbus-monitor does not reply to messages intended for others,
1444 resulting in its own disconnection (fd.o #90952, Simon McVittie)
1446 D-Bus 1.9.16 (2015-05-14)
1449 The “titanium barns” release.
1453 • Automake 1.13 is now required when compiling from git or modifying
1458 • On Unix platforms, change the default configuration for the session bus
1459 to only allow EXTERNAL authentication (secure kernel-mediated
1460 credentials-passing), as was already done for the system bus.
1462 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
1463 unpredictable pseudo-random numbers.
1465 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
1466 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1467 NFS or similar, you will need to reconfigure the session bus to accept
1468 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1471 (fd.o #90414, Simon McVittie)
1473 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1474 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1475 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1476 occurs, instead of silently falling back to low-entropy pseudorandom
1477 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1481 • Add dbus_message_iter_get_element_count()
1482 (fd.o #30350; Christian Dywan, Simon McVittie)
1484 • Introduce new internal DBusSocket and DBusPollable types so we can
1485 stop treating the Windows SOCKET type as if it was int. DBusSocket
1486 is specifically a socket, cross-platform. DBusPollable is whatever
1487 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1488 (fd.o #89444; Ralf Habacker, Simon McVittie)
1490 • All regression tests now output TAP <https://testanything.org/>
1491 (fd.o #89846, Simon McVittie)
1493 • Internal APIs consistently use signed values for timestamps
1494 (fd.o #18494, Peter McCurdy)
1496 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1497 (fd.o #88812, Simon McVittie)
1499 • Clean up a lot of compiler warnings
1500 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1504 • Add locking to DBusCounter's reference count and notify function
1505 (fd.o #89297, Adrian Szyndela)
1507 • Ensure that DBusTransport's reference count is protected by the
1508 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1510 • Correctly release DBusServer mutex before early-return if we run out
1511 of memory while copying authentication mechanisms (fd.o #90021,
1514 • Make dbus-test-tool and dbus-update-activation-environment portable
1515 to Windows (fd.o #90089, Ralf Habacker)
1517 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1518 Ralf Habacker, Simon McVittie)
1520 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1523 • Clean up some memory and fd leaks in test code and tools
1524 (fd.o #90021, Ralf Habacker)
1526 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1527 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1529 • CMake generates a versioned shared library even if the revision is 0,
1530 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1532 D-Bus 1.9.14 (2015-03-02)
1535 The “don't stand in the poison cloud” release.
1539 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1540 were previously linked to a static version of libdbus.
1542 • The tests no longer require dbus-glib in order to exercise the libdbus
1543 shared library; they are always linked to libdbus now.
1545 Build-time configuration:
1547 • The new --enable-user-session option, off by default, can be enabled
1548 by OS integrators intending to use systemd to provide a session bus
1549 per user (in effect, treating all concurrent graphical and non-graphical
1550 login sessions as one large session)
1554 • All executables are now linked dynamically to libdbus.
1555 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1557 • On platforms that support them (GNU libc and possibly others),
1558 libdbus now has versioned symbols for its public API.
1559 All public symbols (visible in the header files) are currently
1560 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1561 dbus_internal have a version that changes with each release, and
1562 must not be used by applications. (also fd.o #83115)
1564 • New listenable address mode "unix:runtime=yes" which listens on
1565 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1566 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1568 • Add optional systemd units for a per-user bus listening on
1569 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1571 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1572 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1575 • New dbus-update-activation-environment tool uploads environment
1576 variables to "dbus-daemon --session" and optionally "systemd --user",
1577 primarily as a way to keep the per-user bus compatible with
1578 distributions' existing X11 login scripts (also fd.o #61301)
1580 • <includedir/> elements in dbus-daemon configuration are now silently
1581 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1583 • Add microsecond-resolution timestamps to the default output of
1584 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1588 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1589 (fd.o #89222, Simon McVittie)
1591 D-Bus 1.9.12 (2015-02-19)
1594 The “monster lasagna” release.
1598 • Ducktype and yelp-tools are now required to build complete documentation
1599 (they are optional for normal builds).
1603 • D-Bus Specification version 0.26
1604 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1605 · document the BecomeMonitor method
1607 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1608 (fd.o #89041; Tyler Hicks, Simon McVittie)
1610 • On Linux, add support for AppArmor mediation of message sending and
1611 receiving and name ownership (paralleling existing SELinux mediation
1612 support), and eavesdropping (a new check, currently AppArmor-specific)
1613 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1615 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1616 that have printable ASCII contents; we previously only did this for
1617 unterminated bytestrings (fd.o #89109, Simon McVittie)
1619 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1621 • On Windows, add WindowsSID to GetConnectionCredentials
1622 (fd.o #54445, Ralf Habacker)
1624 • Improve clarity of dbus-monitor --profile output and add more columns
1625 (fd.o #89165, Ralf Habacker)
1627 • Add a man page for dbus-test-tool, and build it under CMake as well
1628 as Autotools (fd.o#89086, Simon McVittie)
1630 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1631 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1632 (fd.o #88896, Ralf Habacker)
1636 • Reduce the number of file descriptors used in the fd-passing test,
1637 avoiding failure under the default Linux fd limit, and automatically
1638 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1640 D-Bus 1.9.10 (2015-02-09)
1643 The “sad cyborgs” release.
1645 Security fixes merged from 1.8.16:
1647 • Do not allow non-uid-0 processes to send forged ActivationFailure
1648 messages. On Linux systems with systemd activation, this would
1649 allow a local denial of service: unprivileged processes could
1650 flood the bus with these forged messages, winning the race with
1651 the actual service activation and causing an error reply
1652 to be sent back when service auto-activation was requested.
1653 This does not prevent the real service from being started,
1654 so the attack only works while the real service is not running.
1655 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1659 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1660 similar tools receive messages without altering the security properties
1661 of the system bus, by calling the new BecomeMonitor method on a
1662 private connection. This bypasses the normal <allow> and <deny> rules
1663 entirely, so to preserve normal message-privacy assumptions, only root
1664 is allowed to do this on the system bus. Restricted environments,
1665 such as Linux with LSMs, should lock down access to the Monitoring
1666 interface. (fd.o #46787, Simon McVittie)
1668 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1669 dbus-daemon supports it and access permissions allow it.
1670 It still supports the previous approach ("eavesdropping" match rules)
1671 for compatibility with older bus daemons. (fd.o #46787, Simon)
1673 • dbus-monitor can now log the message stream as binary data for later
1674 analysis, with either no extra framing beyond the normal D-Bus headers,
1675 or libpcap-compatible framing treating each D-Bus message
1676 as a captured packet. (fd.o #46787, Simon)
1680 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1682 • On Unix, forcibly terminate regression tests after 60 seconds to
1683 prevent them from blocking continuous integration frameworks
1684 (fd.o #46787, Simon)
1686 D-Bus 1.9.8 (2015-02-03)
1689 The “all the types of precipitation” release.
1693 • full test coverage now requires GLib 2.36
1694 • full test coverage now requires PyGI (PyGObject 3,
1695 "import gi.repository.GObject") instead of the
1696 obsolete PyGObject 2 ("import gobject")
1700 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1702 • better regression test coverage, including systemd activation
1703 (fd.o #57952, #88810; Simon McVittie)
1707 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1708 turned off (fd.o #88808, Simon McVittie)
1710 • TCP sockets on Windows no longer fail to listen approximately 1 time
1711 in 256, caused by a logic error that should have always made it fail but
1712 was mitigated by incorrect endianness for the port number
1713 (fd.o #87999, Ralf Habacker)
1715 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1717 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1718 previous 64, completing a previous fix which only worked under
1719 Autotools (fd.o #71297, Ralf Habacker)
1721 • on Windows, if the IP family is unspecified only use IPv4,
1722 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1724 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1726 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1728 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1731 D-Bus 1.9.6 (2015-01-05)
1734 The “I do have a bread knife” release.
1738 • Do not allow calls to UpdateActivationEnvironment from uids other than
1739 the uid of the dbus-daemon. If a system service installs unsafe
1740 security policy rules that allow arbitrary method calls
1741 (such as CVE-2014-8148) then this prevents memory consumption and
1742 possible privilege escalation via UpdateActivationEnvironment.
1744 We believe that in practice, privilege escalation here is avoided
1745 by dbus-daemon-launch-helper sanitizing its environment; but
1746 it seems better to be safe.
1748 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1749 on object paths other than /org/freedesktop/DBus. Some system services
1750 install unsafe security policy rules that allow arbitrary method calls
1751 to any destination, method and interface with a specified object path;
1752 while less bad than allowing arbitrary method calls, these security
1753 policies are still harmful, since dbus-daemon normally offers the
1754 same API on all object paths and other system services might behave
1759 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1760 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1762 D-Bus 1.9.4 (2014-11-24)
1765 The “extra-sturdy caramel” release.
1769 • Partially revert the CVE-2014-3639 patch by increasing the default
1770 authentication timeout on the system bus from 5 seconds back to 30
1771 seconds, since this has been reported to cause boot regressions for
1772 some users, mostly with parallel boot (systemd) on slower hardware.
1774 On fast systems where local users are considered particularly hostile,
1775 administrators can return to the 5 second timeout (or any other value
1776 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1779 <limit name="auth_timeout">5000</limit>
1782 (fd.o #86431, Simon McVittie)
1784 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1785 (fd.o #86431, Simon McVittie)
1787 • Send back an AccessDenied error if the addressed recipient is not allowed
1788 to receive a message (and in builds with assertions enabled, don't
1789 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1791 D-Bus 1.9.2 (2014-11-10)
1794 The “structurally unsound flapjack” release.
1798 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1799 so that CVE-2014-3636 part A cannot exhaust the system bus'
1800 file descriptors, completing the incomplete fix in 1.8.8.
1801 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1805 • D-Bus Specification version 0.25
1806 · new value 'const' for EmitsChangedSignal annotation

1808 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1809 (fd.o #83449; Lennart Poettering, Simon McVittie)
1810 · annotate table of types with reserved/basic/container, and for
1811 basic types, fixed/string-like
1812 · clarify arbitrary limits by quoting them in mebibytes
1814 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1815 (fd.o #83449, Simon McVittie)
1817 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1818 useful for debugging and performance testing:
1819 · dbus-test-tool spam: send repeated messages
1820 · dbus-test-tool echo: send an empty reply for all method calls
1821 · dbus-test-tool black-hole: do not reply to method calls
1822 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1824 • Add support for process ID in credentials-passing on NetBSD
1825 (fd.o #69702, Patrick Welche)
1827 • Add an example script to find potentially undesired match rules
1828 (fd.o #84598, Alban Crequy)
1830 • Document the central assumption that makes our use of credentials-passing
1831 secure (fd.o #83499, Simon McVittie)
1833 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1834 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1839 • Use a less confusing NoReply message when disconnected with a reply pending
1840 (fd.o #76112, Simon McVittie)
1842 • Make the .pc file relocatable by letting pkg-config do all variable
1843 expansion itself (fd.o #75858, Руслан Ижбулатов)
1845 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1846 (fd.o #85563, Patrick Welche)
1848 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1850 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1851 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1853 • Do not fail the tests if a parent process has leaked non-close-on-exec
1854 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1856 • Do not fail the tests on Unix platforms with incomplete
1857 credentials-passing support, but do fail if we can't pass credentials
1858 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1859 (fd.o #69702, Simon McVittie)
1861 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1862 when building with cmake, and expand test coverage there
1863 (fd.o #73689; Ralf Habacker, Simon McVittie)
1865 D-Bus 1.9.0 (2014-10-01)
1868 The “tiered cheeses” release.
1872 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1873 requires either the libsystemd or libsd-daemon shared library, dropping the
1874 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1876 Build-time configuration changes:
1878 • The Stats interface is now enabled by default, and locked-down to
1879 root-only on the system bus. Configure with --disable-stats
1880 to disable it altogether on memory- or disk-constrained systems,
1881 or see ${docdir}/examples/ to open it up to non-root users on the
1882 system bus or restrict access on the session bus.
1883 (fd.o #80759; Simon McVittie, Alban Crequy)
1885 • The CMake build system now builds the same shared library name as Autotools
1886 on at least Linux and Windows:
1887 - on Linux (and perhaps other Unix platforms), it previously built
1888 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1889 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1890 - on Windows, it previously built either libdbus-1.dll (release) or
1891 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1892 libdbus-1.dll for compatibility with older applications.
1893 (fd.o #74117, Ralf Habacker)
1897 • D-Bus Specification version 0.24
1898 · document how to quote match rules (fd.o #24307, Simon McVittie)
1899 · explicitly say that most message types never expect a reply
1900 regardles of whether they have NO_REPLY_EXPECTED
1901 (fd.o #75749, Simon McVittie)
1903 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
1904 initial latency (fd.o #75544, Matt Hoosier)
1906 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
1907 (fd.o #69702, Patrick Welche)
1909 • in dbus-monitor, print more information about file descriptors
1910 (fd.o #80603, Alban Crequy)
1912 • do not install system bus configuration if built for Windows
1913 (fd.o #83583; Ralf Habacker, Simon McVittie)
1915 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
1917 • Add a regression test for file descriptor passing (fd.o #83622,
1922 • fix an incorrect error message if a Unix socket path is too long
1923 (fd.o #73887, Antoine Jacoutot)
1925 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
1926 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
1928 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
1929 in ps(1) (fd.o #69716, Chengwei Yang)
1931 • avoid calling poll() with timeout < -1, which is considered invalid
1932 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
1934 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
1935 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
1936 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
1938 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
1940 • Documentation improvements
1941 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
1943 • in dbus-monitor, do not leak file descriptors that we have monitored
1944 (fd.o #80603, Alban Crequy)
1946 • Set the close-on-exec flag for the inotify file descriptor, even
1947 if built with CMake or older libc (fd.o #73689, Simon McVittie)
1949 • Remove some LGPL code from the Windows dbus-daemon
1950 (fd.o #57272, Ralf Habacker)
1952 D-Bus 1.8.8 (2014-09-16)
1955 The "smashy smashy egg man" release.
1959 • Do not accept an extra fd in the padding of a cmsg message, which
1960 could lead to a 4-byte heap buffer overrun.
1961 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1963 • Reduce default for maximum Unix file descriptors passed per message
1964 from 1024 to 16, preventing a uid with the default maximum number of
1965 connections from exhausting the system bus' file descriptors under
1966 Linux's default rlimit. Distributors or system administrators with a
1967 more restrictive fd limit may wish to reduce these limits further.
1969 Additionally, on Linux this prevents a second denial of service
1970 in which the dbus-daemon can be made to exceed the maximum number
1971 of fds per sendmsg() and disconnect the process that would have
1973 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1975 • Disconnect connections that still have a fd pending unmarshalling after
1976 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1977 removing the possibility of creating an abusive connection that cannot be
1978 disconnected by setting up a circular reference to a connection's
1980 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1982 • Reduce default for maximum pending replies per connection from 8192 to 128,
1983 mitigating an algorithmic complexity denial-of-service attack
1984 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1986 • Reduce default for authentication timeout on the system bus from
1987 30 seconds to 5 seconds, avoiding denial of service by using up
1988 all unauthenticated connection slots; and when all unauthenticated
1989 connection slots are used up, make new connection attempts block
1990 instead of disconnecting them.
1991 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1995 • Check for libsystemd from systemd >= 209, falling back to
1996 the older separate libraries if not found (Umut Tezduyar Lindskog,
1999 • On Linux, use prctl() to disable core dumps from a test executable
2000 that deliberately raises SIGSEGV to test dbus-daemon's handling
2001 of that condition (fd.o #83772, Simon McVittie)
2003 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
2006 • Improve documentation for running tests on Windows (fd.o #41252,
2009 D-Bus 1.8.6 (2014-06-02)
2014 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
2015 the message. This prevents an attack in which a malicious client can
2016 make dbus-daemon disconnect a system service, which is a local
2018 (fd.o #80163, CVE-2014-3532; Alban Crequy)
2020 • Track remaining Unix file descriptors correctly when more than one
2021 message in quick succession contains fds. This prevents another attack
2022 in which a malicious client can make dbus-daemon disconnect a system
2024 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
2025 Simon McVittie, Alban Crequy)
2029 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
2030 attach to a session, kill the dbus-daemon as intended
2031 (fd.o #74698, Роман Донченко)
2033 D-Bus 1.8.4 (2014-06-10)
2038 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
2039 flaw in dbus-daemon, part of the reference implementation of D-Bus.
2040 Additionally, in highly unusual environments the same flaw could lead to
2041 a side channel between processes that should not be able to communicate.
2042 (CVE-2014-3477, fd.o #78979)
2044 D-Bus 1.8.2 (2014-04-30)
2047 The “nobody wants red” release.
2051 • in the CMake build system, add some hints for Linux users cross-compiling
2052 Windows D-Bus binaries to be able to run tests under Wine
2053 (fd.o #41252, Ralf Habacker)
2055 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
2059 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
2060 to /var/lib/dbus/machine-id instead of generating an entirely new ID
2061 (fd.o #77941, Simon McVittie)
2063 • if dbus-launch receives an X error very quickly, do not kill
2064 unrelated processes (fd.o #74698, Роман Донченко)
2066 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
2067 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
2069 • cope with \r\n newlines in regression tests, since on Windows,
2070 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
2072 D-Bus 1.8.0 (2014-01-20)
2075 The “Wolverine distrusts my printer” release.
2077 This starts a new stable branch. The 1.6.x branch is now considered to be
2078 outdated, and will only receive fixes for serious bugs such as security
2079 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
2080 are unlikely to get any more releases, but if distributors still need to
2081 support them, please share security patches via upstream.
2083 Summary of changes since 1.6.x:
2085 • libdbus always behaves as if dbus_threads_init_default() had been called
2086 (thread-safety by default)
2087 • new dbus-run-session tool, replacing certain misuses of dbus-launch
2088 • dbus-monitor can talk to outdated versions of dbus-daemon again
2089 • new org.freedesktop.DBus.GetConnectionCredentials method
2090 • GetConnectionUnixProcessID also works correctly on Windows, returning
2091 the Windows process ID
2092 • GetConnectionWindowsSID returns the correct SID on Windows
2093 • expat is required, libxml2 can no longer be used as a substitute
2094 • the userDB cache is required, and cannot be disabled
2095 • a 64-bit integer type (either int, long, long long or _int64) is required
2096 • better systemd-journald integration on Linux
2097 • fixed long-standing fd and array leaks when failing to parse a message
2098 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
2099 when using certain object-path allocation patterns, notably in Avahi
2100 • better defaults for Windows support
2101 • better CMake support
2102 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
2103 • the source language for the man pages is now Docbook XML
2105 Enhancements since 1.7.10:
2107 • Enhance the CMake build system to check for GLib and compile/run
2108 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
2112 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
2115 • fix compilation of systemd journal support on older systemd versions where
2116 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
2118 • fix compilation on older MSVC versions by including stdlib.h
2119 (fd.o #73455, Ralf Habacker)
2121 • Allow <allow_anonymous/> to appear in an included configuration file
2122 (fd.o #73475, Matt Hoosier)
2124 Test behaviour changes since 1.7.10:
2126 • If the tests crash with an assertion failure, they no longer default to
2127 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
2128 environment if you want the old behaviour.
2130 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
2131 can be run with an external dbus-daemon by setting
2132 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
2133 an unusually-configured dbus-daemon are skipped.
2135 D-Bus 1.7.10 (2014-01-06)
2138 The “weighted companion cube” release.
2140 This is a release candidate for D-Bus 1.8.
2142 D-Bus Specification 0.23:
2144 • don't require messages with no INTERFACE to be dispatched
2145 (fd.o #68597, Simon McVittie)
2147 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
2150 • define "listenable" and "connectable" addresses, and discuss
2151 the difference (fd.o #61303, Simon McVittie)
2155 • support printing Unix file descriptors in dbus-send, dbus-monitor
2156 (fd.o #70592, Robert Ancell)
2158 • don't install systemd units if --disable-systemd is given
2159 (fd.o #71818, Chengwei Yang)
2163 • don't leak memory on out-of-memory while listing activatable or
2164 active services (fd.o #71526, Radoslaw Pajak)
2166 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
2168 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
2170 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
2171 and DBUS__SEND_MSG are numerically equal to their values in the
2172 reference policy (fd.o #88719, osmond sun)
2174 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
2175 (fd.o #71366, Matt Fischer)
2177 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
2178 winsock2.h (fd.o #71405, Matt Fischer)
2180 • do not return failure from _dbus_read_nonce() with no error set,
2181 preventing a potential crash (fd.o #72298, Chengwei Yang)
2183 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
2184 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
2186 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
2187 which doesn't do anything anyway on at least Linux and FreeBSD
2188 (fd.o #69492, Simon McVittie)
2190 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
2191 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
2192 for credentials more correctly (fd.o #69492, Simon McVittie)
2194 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
2195 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
2198 • refresh cached policy rules for existing connections when bus
2199 configuration changes (fd.o #39463, Chengwei Yang)
2201 D-Bus 1.7.8 (2013-11-01)
2204 The “extreme hills” release.
2208 • If systemd support is enabled, libsystemd-journal is now required.
2212 • When activating a non-systemd service under systemd, annotate its
2213 stdout/stderr with its bus name in the Journal. Known limitation:
2214 because the socket is opened before forking, the process will still be
2215 logged as if it had dbus-daemon's process ID and user ID.
2216 (fd.o #68559, Chengwei Yang)
2218 • Document more configuration elements in dbus-daemon(1)
2219 (fd.o #69125, Chengwei Yang)
2223 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
2224 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
2226 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
2227 disallowed method calls to the audit log, fixing a regression in 1.7.6
2228 (fd.o #49062, Colin Walters)
2230 • path_namespace='/' in match rules incorrectly matched nothing; it
2231 now matches everything. (fd.o #70799, Simon McVittie)
2233 D-Bus 1.7.6 (2013-10-09)
2236 The “CSI Shrewsbury” release.
2238 Build-time configuration changes:
2240 • Directory change notification via dnotify on Linux is no longer
2241 supported; it hadn't compiled successfully since 2010 in any case.
2242 If you don't have inotify (Linux) or kqueue (*BSD), you will need
2243 to send SIGHUP to the dbus-daemon when its configuration changes.
2244 (fd.o #33001, Chengwei Yang)
2246 • Compiling with --disable-userdb-cache is no longer supported;
2247 it didn't work since at least 2008, and would lead to an extremely
2248 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
2251 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
2252 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
2253 with the Autotools build system. (fd.o #66142, Chengwei Yang)
2255 • --with-valgrind=auto enables Valgrind instrumentation if and only if
2256 valgrind headers are available. The default is still --with-valgrind=no.
2257 (fd.o #56925, Simon McVittie)
2261 • Platforms with no 64-bit integer type are no longer supported.
2262 (fd.o #65429, Simon McVittie)
2264 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
2266 • Full test coverage no longer requires dbus-glib, although the tests do not
2267 exercise the shared library (only a static copy) if dbus-glib is missing.
2268 (fd.o #68852, Simon McVittie)
2272 • D-Bus Specification 0.22
2273 · Document GetAdtAuditSessionData() and
2274 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
2275 · Fix example .service file (fd.o #66481, Chengwei Yang)
2276 · Don't claim D-Bus is "low-latency" (lower than what?), just
2277 give factual statements about it supporting async use
2278 (fd.o #65141, Justin Lee)
2279 · Document the contents of .service files, and the fact that
2280 system services' filenames are constrained
2281 (fd.o #66608; Simon McVittie, Chengwei Yang)
2283 • Be thread-safe by default on all platforms, even if
2284 dbus_threads_init_default() has not been called. For compatibility with
2285 older libdbus, library users should continue to call
2286 dbus_threads_init_default(): it is harmless to do so.
2287 (fd.o #54972, Simon McVittie)
2289 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
2291 • New API: dbus_setenv(), a simple wrapper around setenv().

2411 of service for system services. Vulnerability reported by Alexandru Cornea.
2416 • The Windows version of libdbus now contains a C++ source file, used
2417 to provide global initialization when the library is loaded.
2418 gcc (mingw*) users should ensure that g++ is also installed.
2420 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
2421 and was never the recommended option) has been removed. Expat is now a
2426 • It should now be safe to call dbus_threads_init_default() from any thread,
2427 at any time. Authors of loadable modules and plugins that use libdbus
2428 should consider doing so during initialization.
2429 (fd.o #54972, Simon McVittie)
2431 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
2435 · dbus-run-session: experimental new tool to start a temporary D-Bus

2513 remains the recommended version for long-term-supported distributions
2514 or the upcoming GNOME 3.8 release.
2516 Build-time configuration changes:
2518 • The --with-dbus-session-bus-default-address configure option is no longer
2519 supported. Use the new --with-dbus-session-bus-connect-address and
2520 --with-dbus-session-bus-listen-address options instead. On Windows, you
2521 usually want them to have the same argument; on Unix, the defaults are
2524 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2525 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2526 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2528 • cmake/cross-compile.sh has been removed. Instead, please use a
2529 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2530 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2531 as documented in "info automake Cross-Compilation", and set
2532 PKG_CONFIG_PATH appropriately.

2543 implements o.fd.DBus (fd.o #51865, Colin Walters)
2544 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
2545 · stop claiming that all basic types work just like INT32 (strings don't!)
2547 • The "source code" for the man pages is now Docbook XML, eliminating
2548 the outdated duplicate copies used when building with CMake.
2549 (fd.o #59805; Ralf Habacker, Simon McVittie)
2553 • In the activation helper, when compiled for tests, do not reset the system
2554 bus address, fixing the regression tests. (fd.o #52202, Simon)

2581 · The default session bus listening and connecting address is now
2582 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2583 and GDBus "out of the box". Use the configure options and cmake variables
2584 described above if you require a different autolaunch scope.
2585 (fd.o #38201, Simon McVittie)

2645 Automake maintainer mode. D-Bus developers should now configure with
2646 --enable-developer. Automake maintainer mode is now on by default;
2647 distributions can disable it with --disable-maintainer-mode.
2648 (fd.o #34671, Simon McVittie)
2650 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,

2745 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2746 and SUSv2) is now required.
2748 • D-Bus Specification 0.19:
2749 · Formally define unique connection names and well-known bus names,
2750 and document best practices for interface, bus, member and error names,
2751 and object paths (fd.o #37095, Simon McVittie)

2788 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2789 setups where the default configuration must include <pidfile/> to avoid
2790 breaking traditional init, but the pid file is in fact unnecessary; use
2791 it under systemd to improve startup time a bit (fd.o #45520,

2811 · Replace our broken reimplementation of recursive mutexes, which has
2812 been broken since 2006, with an ordinary pthreads recursive mutex
2813 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2814 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2815 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2816 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2817 · When running under systemd, use it instead of ConsoleKit to check
2818 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2819 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2820 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2821 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2822 (fd.o #41218, Simon McVittie)
2823 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2824 helper doesn't obey environment variables to avoid privilege escalation
2825 attacks, so make the system bus follow the same rules
2826 (fd.o #21620, Simon McVittie)
2829 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2830 Jesper Dam, Ralf Habacker)

2834 D-Bus 1.5.8 (2011-09-21)
2837 The "cross-metering" release.
2839 In addition to dead code removal and refactoring, this release contains all
2840 of the bugfixes from 1.4.16.
2842 • Clean up dead code, and make more warnings fatal in development builds
2843 (fd.o #39231, fd.o #41012; Simon McVittie)
2845 • If full test coverage is requested via --enable-tests, strictly require
2846 Python, pygobject and dbus-python, which are required by some tests; if not,
2847 and Python is missing, skip those tests rather than failing
2848 (fd.o #37847, Simon McVittie)
2850 • When using cmake, provide the same version-info API in the installed headers
2851 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2853 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
2855 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
2857 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
2860 • Fix duplicates in authors list (Ralf Habacker)
2862 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2863 (fd.o #39879, Chris Mayo)
2865 • Fix a small memory leak, and a failure to report errors, when updating
2866 a service file entry for activation (fd.o #39230, Simon McVittie)
2869 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2870 Brian Cameron, Simon McVittie)
2871 · On systems that use libcap-ng but not systemd, drop supplemental groups
2872 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2873 · Make the cmake build work again on GNU platforms (fd.o #29228,
2875 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
2876 like Solaris (fd.o #40313, Dagobert Michelsen)
2877 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2878 (fd.o #40235, Simon McVittie)
2879 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2880 (fd.o #39987, Simon McVittie)
2881 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2882 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2885 · Fix compilation on MSVC, which doesn't understand "inline" with its
2886 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2887 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2888 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2890 D-Bus 1.5.6 (2011-07-29)
2893 The "weird, gravy-like aftertaste" release.
2895 In addition to new features and refactoring, this release contains all of the
2896 bugfixes from 1.4.14.
2898 Potentially incompatible (Bustle and similar debugging tools will need
2899 changes to work as intended):
2901 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2902 different recipient) by mistake: eavesdroppers must now opt-in to this
2903 behaviour by putting "eavesdrop='true'" in the match rule, which will
2904 not have any practical effect on buses where eavesdropping is not allowed
2905 (fd.o #37890, Cosimo Alfarano)
2909 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2910 Cosimo Alfarano, Simon McVittie)
2911 · add the "eavesdrop" keyword to match rules
2912 · define eavesdropping, unicast messages and broadcast messages
2913 · stop claiming that match rules are needed to match unicast messages to you
2914 · promote the type system to be a top-level section
2916 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2917 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2918 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2920 • Consistently use atomic operations on everything that is ever manipulated
2921 via atomic ops, as was done for changes to DBusConnection's refcount in
2922 1.4.12 (fd.o #38005, Simon McVittie)
2924 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2927 • Make "make check" in a clean tree work, by not running tests until
2928 test data has been set up (fd.o #34405, Simon McVittie)
2930 • The dbus-daemon no longer busy-loops if it has a very large number of file
2931 descriptors (fd.o #23194, Simon McVittie)
2933 • Refactor message flow through dispatching to avoid locking violations if
2934 the bus daemon's message limit is hit; remove the per-connection link cache,
2935 which was meant to improve performance, but now reduces it (fd.o #34393,
2938 • Some cmake fixes (Ralf Habacker)
2940 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2941 Simon McVittie, Lennart Poettering)
2943 • Stop storing two extra byte order indicators in each D-Bus message
2944 (fd.o #38287, Simon McVittie)
2946 • Add an optional Stats interface which can be used to get statistics from
2947 a running dbus-daemon if enabled at configure time with --enable-stats
2948 (fd.o #34040, Simon McVittie)
2950 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2952 • Documentation (fd.o #36156, Simon McVittie):
2953 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2954 · install more documentation automatically, including man2html output
2955 · put dbus.devhelp in the right place (it must go in ${htmldir})
2958 · look for system services in /lib/dbus-1/system-services in addition to all
2959 the other well-known locations; note that this should always be /lib,
2960 even on platforms where shared libraries on the root FS would go in /lib64,
2961 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2962 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2964 • Windows-specific (Ralf Habacker):
2965 · fix use of a mutex for autolaunch server detection
2966 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2968 D-Bus 1.5.4 (2011-06-10)
2971 Security (local denial of service):
2973 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2974 local DoS if foreign-endian messages are relayed through the dbus-daemon
2975 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2976 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2980 • The constant to use for an infinite timeout now has a name,
2981 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2982 which can be used for source compatibility with older versions of libdbus.
2984 • If GLib and DBus-GLib are already installed, more tests will be built,
2985 providing better coverage. The new tests can also be installed via
2986 ./configure --enable-installed-tests
2987 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2991 • Consistently use atomic operations for the DBusConnection's refcount,
2992 fixing potential threading problems (fd.o #38005, Simon McVittie)
2994 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2995 small (300KiB on x86-64) and it frequently doesn't work in unusual
2996 toolchains. To optimize for minimum installed size, you should benchmark
2997 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2998 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
3000 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
3001 (fd.o #35880, Timothy Redaelli)
3003 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
3004 when not using a DESTDIR (fd.o #37870, Simon McVittie)
3006 • Windows-specific changes:
3007 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
3009 D-Bus 1.5.2 (2011-06-01)
3012 The "Boar Hunter" release.
3014 Notes for distributors:
3016 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
3017 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
3018 toolchain supports it reliably, via something like:
3020 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
3022 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
3026 • D-Bus Specification v0.17
3027 · Reserve the extra characters used in signatures by GVariant
3028 (fd.o #34529, Simon McVittie)
3029 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
3030 • Don't force -fPIE: distributions and libtool know better than we do whether
3031 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
3032 • Allow --disable-gc-sections, in case your toolchain offers the
3033 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
3034 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
3035 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
3036 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
3037 • Ensure that maintainers upload documentation with the right permissions
3038 (fd.o #36130, Simon McVittie)
3039 • Don't force users of libdbus to be linked against -lpthread, -lrt
3040 (fd.o #32827, Simon McVittie)
3041 • Log system-bus activation information to syslog (fd.o #35705,
3043 • Log messages dropped due to quotas to syslog (fd.o #35358,
3045 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
3046 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
3047 (fd.o #35228, Lennart Poettering)
3048 • In the regression tests, don't report fds as "leaked" if they were open
3049 on startup (fd.o #35173, Simon McVittie)
3050 • Make dbus-monitor bail out if asked to monitor more than one bus,
3051 rather than silently using the last one (fd.o #26548, Will Thompson)
3052 • Clarify documentation (fd.o #35182, Simon McVittie)
3053 • Clean up minor dead code and some incorrect error handling
3054 (fd.o #33128, fd.o #29881; Simon McVittie)
3055 • Check that compiler options are supported before using them (fd.o #19681,
3058 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
3060 D-Bus 1.5.0 (2011-04-11)
3063 The "you never know when you need to tow something from your giant
3064 flying shark" release.
3066 • D-Bus Specification v0.16
3067 · Add support for path_namespace and arg0namespace in match rules
3068 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
3069 · Make argNpath support object paths, not just object-path-like strings,
3070 and document it better (fd.o #31818, Will Thompson)
3071 • Let the bus daemon implement more than one interface (fd.o #33757,
3073 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
3075 • Require user intervention to compile with missing 64-bit support
3076 (fd.o #35114, Simon McVittie)
3077 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
3078 • Raise UnknownObject instead of UnknownMethod for calls to methods on
3079 paths that are not part of the object tree, and UnknownInterface for calls
3080 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
3082 D-Bus 1.4.8 (2011-04-08)
3085 The "It's like the beginning of a lobster" release.
3087 • Rename configure.in to configure.ac, and update it to modern conventions
3088 (fd.o #32245; Javier Jardón, Simon McVittie)
3089 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
3091 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
3092 --disable-x11-autolaunch configure option to prevent it altogether
3093 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
3094 • Install the documentation, and an index for Devhelp (fd.o #13495,
3095 Debian #454142; Simon McVittie, Matthias Clasen)
3096 • If checks are not disabled, check validity of string-like types and
3097 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
3098 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
3099 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
3100 • Break up a huge conditional in config-parser so gcov can produce coverage
3101 data (fd.o #10887, Simon McVittie)
3102 • List which parts of the Desktop Entry specification are applicable to
3103 .service files (fd.o #19159, Sven Herzberg)
3104 • Don't suppress service activation if two services have the same Exec=
3105 (fd.o #35750, Colin Walters)

3115 The "1, 2, miss a few, 99, 100" release.
3117 • Remove unfinished changes intended to support GTest-based tests,
3118 which were mistakenly included in 1.4.4
3120 D-Bus 1.4.4 (2010-02-17)
3123 • Switch back to using even micro versions for stable releases; 1.4.1
3124 should have been called 1.4.2, so skip that version number
3125 • Don't leave bad file descriptors being watched when spawning processes,
3126 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
3127 also LP#656134, LP#680444, LP#713157)
3128 • Check for MSG_NOSIGNAL correctly
3129 • Fix failure to detect abstract socket support (fd.o #29895)
3130 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
3131 (fd.o #32262, NB#180486)

3158 D-Bus 1.4.1 (20 December 2010)
3161 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
3162 crash the bus. The existing restriction to 64-levels of nesting previously
3163 only applied to the static type signature; now it also applies to dynamic
3164 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
3166 • OS X portability fixes, including launchd support.
3167 • Windows autolaunch improvements.
3168 • Various bug fixes.
