1 dbus 1.12.14 (2019-05-17)
2 =========================
4 The “reclaimed floorboards” release.
8 • Raise soft fd limit to match hard limit, even if unprivileged.
9 This makes session buses with many clients, or with clients that make
10 heavy use of fd-passing, less likely to suffer from fd exhaustion.
11 (dbus!103, Simon McVittie)
15 • If a privileged dbus-daemon has a hard fd limit greater than 64K, don't
16 reduce it to 64K, ensuring that we can put back the original fd limits
17 when carrying out traditional (non-systemd) activation. This fixes a
18 regression with systemd >= 240 in which system services inherited
19 dbus-daemon's hard and soft limit of 64K fds, instead of the intended
20 soft limit of 1K and hard limit of 512K or 1M.
21 (dbus!103, Debian#928877; Simon McVittie)
23 • Fix build failures caused by an AX_CODE_COVERAGE API change in newer
24 autoconf-archive versions (dbus#249, dbus!88; Simon McVittie)
26 • Fix build failures with newer autoconf-archive versions that include
27 AX_-prefixed shell variable names (dbus#249, dbus!86; Simon McVittie)
29 • Parse section/group names in .service files according to the syntax
30 from the Desktop Entry Specification, rejecting control characters
31 and non-ASCII in section/group names (dbus#208, David King)
33 • Fix various -Wlogical-op issues that cause build failure with newer
34 gcc versions (dbus#225, dbus!109; David King)
36 • Don't assume we can set permissions on a directory, for the benefit of
37 MSYS and Cygwin builds (dbus#216, dbus!110; Simon McVittie)
39 • Don't overwrite PKG_CONFIG_PATH and related environment variables when
40 the pkg-config-based version of DBus1Config is used in a CMake project
41 (dbus#267, dbus!96; Clemens Lang)
43 dbus 1.12.12 (2018-12-04)
44 =========================
46 The “draconic disciple” release.
48 dbus version control is now hosted on freedesktop.org's Gitlab
49 installation, and bug reports and feature requests have switched from
50 Bugzilla bugs (indicated by "fd.o #nnn") to Gitlab issues ("dbus#nnn")
51 and merge requests ("dbus!nnn").
55 • Reference the freedesktop.org Code of Conduct (Simon McVittie)
59 • Stop the dbus-daemon leaking memory (an error message) if delivering
60 the message that triggered auto-activation is forbidden. This is
61 technically a denial of service because the dbus-daemon will
62 run out of memory eventually, but it's a very slow and noisy one,
63 because all the rejected messages are also very likely to have
64 been logged to the system log, and its scope is typically limited by
65 the finite number of activatable services available.
66 (dbus#234, Simon McVittie)
68 • Remove __attribute__((__malloc__)) attribute on dbus_realloc(),
69 which does not meet the criteria for that attribute in gcc 4.7+,
70 potentially leading to miscompilation (fd.o #107741, Simon McVittie)
72 • Fix some small O(1) memory leaks (fd.o #107320, Simon McVittie)
74 • Fix printf formats for pointer-sized integers on 64-bit Windows
75 (fd.o #105662, Ralf Habacker)
77 • Always use select()-based poll() emulation on Darwin-based OSs
78 (macOS, etc.) and on Interix, similar to what libcurl does
79 (dbus#232, dbus!19; Simon McVittie)
81 • Extend a test timeout to avoid spurious failures in CI
82 (dbus!26, Simon McVittie)
86 • Add Travis-CI builds for 64-bit Windows using mingw-w64
87 (fd.o #105662, Ralf Habacker)
89 • Add Gitlab-CI integration (fd.o #108177, Simon McVittie)
91 dbus 1.12.10 (2018-08-02)
92 =========================
94 The “beam deflection” release.
98 • Prevent reading up to 3 bytes beyond the end of a truncated message.
99 This could in principle be an information leak or denial of service
100 on the system bus, but is not believed to be exploitable to crash
101 the system bus or leak interesting information in practice.
102 (fd.o #107332, Simon McVittie)
104 • Fix build with gcc 8 -Werror=cast-function-type
105 (fd.o #107349, Simon McVittie)
107 • Fix warning from gcc 8 about suspicious use of strncpy() when
108 populating struct sockaddr_un (fd.o #107350, Simon McVittie)
110 • Fix a minor memory leak when a DBusServer listens on a new address
111 (fd.o #107194, Simon McVittie)
113 • Fix an invalid NULL argument to rmdir() if a nonce-tcp DBusServer
114 runs out of memory (fd.o #107194, Simon McVittie)
116 • Don't use misleading errno-derived error names if getaddrinfo() or
117 getnameinfo() fails with a code other than EAI_SYSTEM
118 (fd.o #106395, Simon McVittie)
120 • Skip tests that require working TCP if we are in a container environment
121 where 127.0.0.1 cannot be resolved (fd.o #106812, Simon McVittie)
123 dbus 1.12.8 (2018-04-30)
124 ========================
126 The “golden super-velociraptor” release.
130 • The Devhelp documentation index is now in version 2 format
131 (fd.o #106186, Simon McVittie)
133 • Give the dbus-daemon man page some scarier warnings about
134 <allow_anonymous/> and non-local TCP, which are insecure and should
135 not be used, particularly for the standard system and session buses
136 (fd.o #106004, Simon McVittie)
140 • Fix installation of Ducktype documentation with newer yelp-build
141 versions (fd.o #106171, Simon McVittie)
143 dbus 1.12.6 (2018-03-01)
144 ========================
146 The “just the one swan, actually” release.
150 • Increase system dbus-daemon's RLIMIT_NOFILE rlimit before it drops
151 privileges, because it won't have permission afterwards. This fixes a
152 regression in dbus 1.10.18 and 1.11.0 which made the standard system bus
153 more susceptible to deliberate or accidental denial of service.
154 (fd.o #105165, David King)
156 dbus 1.12.4 (2018-02-08)
157 ========================
159 The “Stria Campania 115” release.
163 • When iterating the DBusConnection while blocking on a pending call,
164 don't wait for I/O if that pending call already has a result; and make
165 sure that whether it has a result is propagated in a thread-safe way.
166 This prevents certain multi-threaded calling patterns from blocking
167 until their timeout even when they should have succeeded sooner.
168 (fd.o #102839; Manish Narang, Michael Searle)
170 • Report the correct error if OOM is reached while trying to listen
171 on a TCP socket (fd.o #89104, Simon McVittie)
173 • Fix assertion failures in recovery from OOM while setting up a
174 DBusServer (fd.o #89104, Simon McVittie)
176 • Add a missing space to a warning message (fd.o #103729, Thomas Zajic)
178 • Expand ${bindir} correctly when pkg-config is asked for dbus_daemondir
179 (fd.o #104265, Benedikt Heine)
181 • On Linux systems with systemd < 237, if ${localstatedir}/dbus doesn't
182 exist, create it before trying to create ${localstatedir}/dbus/machine-id
183 (fd.o #104577, Chris Lesiak)
185 • Fix escaping in dbus-api-design document (fd.o #104925, Philip Withnall)
187 dbus 1.12.2 (2017-11-13)
188 ========================
190 The “spider pumpkin” release.
194 • Log a warning if a new connection cannot be accepted due to an
195 out-of-memory condition or failure to identify its AppArmor or
196 SELinux context (fd.o #103592, Simon McVittie)
200 • Make use of $(MKDIR_P) compatible with install-sh, fixing build when a
201 GNU-compatible `mkdir -p` is not available (fd.o #103521, ilovezfs)
203 • When building for Windows with Autotools, avoid `echo -e`, fixing
204 cross-compilation on non-GNU platforms like macOS
205 (fd.o #103493, Tony Theodore)
207 • Fix crashes in the server side of the nonce-tcp: transport under
208 various error conditions. This transport should normally only be used
209 on Windows, where AF_UNIX sockets are unavailable; the unix: transport
210 is the only one recommended for production use on Unix platforms.
211 (fd.o #103597, Simon McVittie)
215 • Improve test coverage on Travis-CI (Simon McVittie)
217 dbus 1.12.0 (2017-10-30)
218 ========================
220 The “gingerbread skull” release.
222 1.12.x is a new stable branch, recommended for use in OS
225 Summary of major changes between 1.10.x and 1.12.0
226 --------------------------------------------------
230 • Expat >= 2.1.0 is required.
231 • GLib >= 2.40 is required if full test coverage is enabled.
232 • [Linux] libselinux >= 2.0.86 is required if SELinux support is
234 • [Unix] dbus now requires an <inttypes.h> that defines C99 constants
235 such as PRId64 and PRIu64, except when building for Windows.
236 • [Autotools] Building from git (but not from tarballs) with Autotools
237 now requires macros from the GNU Autoconf Archive.
238 • [CMake] Builds done using CMake now require CMake 3.0.2.
240 Build-time configuration changes:
242 • Expat is now found using pkg-config. See the release notes for
244 • The --disable-compiler-optimisations and --enable-compiler-coverage
245 options no longer exist. See the release notes for 1.11.4 and 1.11.8.
246 • [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
247 options no longer exist. See the release notes for 1.11.20.
248 • [Unix] Flag files in /var/run/console/${username} are no longer
249 checked for at_console by default. See the release notes for 1.11.18.
250 • [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
251 and packagers will now need to add these downstream (most already do).
252 See the release notes for 1.11.18.
253 • [Unix] The process ID file no longer has a different default location
254 on Red Hat derivatives. See the release notes for 1.11.18.
255 • [Unix] ${runstatedir} is now independent of ${localstatedir} with
256 recent Autotools versions. See the release notes for 1.11.16.
257 • [Windows] The WINDRES variable is no longer used. See the release
262 • Eavesdropping is officially deprecated in favour of BecomeMonitor.
263 See the release notes for spec version 0.31 (in dbus 1.11.14).
264 • [Unix] Flag files in /var/run/console/${username} are deprecated.
265 See the release notes for 1.11.18.
269 • <allow> and <deny> rules in dbus-daemon configuration can now
270 include send_broadcast="true", send_broadcast="false",
271 max_unix_fds="N", min_unix_fds="N" (for some integer N).
272 See the release notes for 1.11.18.
273 • dbus_try_get_local_machine_id() is like
274 dbus_get_local_machine_id(), but returns a DBusError.
275 • New APIs around DBusMessageIter to simplify cleanup.
276 See the release notes for 1.11.16.
277 • The message bus daemon now implements the standard Introspectable,
278 Peer and Properties interfaces. See the release notes for
279 dbus 1.11.14 and spec version 0.31.
280 • DTDs for introspection XML and bus configuration are installed.
281 • dbus can be compiled to be relocatable, making it more suitable for
282 binary bundling with other software. On Windows, this is on by
284 • [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
285 never uses Linux abstract sockets, which is advantageous for
286 containers. On non-Linux it is equivalent to unix:tmpdir=….
287 See the release notes for dbus 1.11.14 and spec version 0.31.
288 • [Unix] New option "dbus-launch --exit-with-x11".
289 • [Unix] Session managers can create transient .service files in
290 $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
291 • [Unix] A sysusers.d snippet can create the messagebus user on-demand.
293 Miscellaneous behaviour changes:
295 • [Unix] The session bus now logs to syslog if it was started by
297 • [Unix] Internal warnings are logged to syslog if configured.
298 • [Unix] Exceeding an anti-DoS limit is logged to syslog if configured,
301 Changes since 1.11.22 release candidate
302 ---------------------------------------
304 Standard stable-branch changes:
306 • Disable warnings about use of deprecated functions (Simon McVittie)
310 • Don't distribute files generated by ./configure in the source tarball
311 (fd.o #103420, Simon McVittie)
315 • Remove some unused files from the git repository
316 (fd.o #103420, Simon McVittie)
318 D-Bus 1.11.22 (2017-10-23)
319 ==========================
321 The “fire surface” release.
323 This is the first release-candidate for the 1.12.0 stable release.
325 Build-time configuration changes:
327 • When building for Windows with Autotools, setting the WINDRES variable
328 no longer works to select a non-standard resource compiler. Use
329 libtool's standard RC variable instead, for example
330 "./configure RC=i686-w64-mingw32-windres"
334 • Builds done using CMake now require CMake 3.0.2.
338 • When building for Windows, improve quality of metadata in
339 libdbus-1-3.dll (fd.o #103015, Ralf Habacker)
343 • Fix a typo "uint 16" in dbus-send(1) man page
344 (fd.o #103075, David King)
346 • When building for Windows, libdbus-1-3.dll always includes version
347 information. Previously, this was missing if using CMake and any
348 non-MSVC compiler. (fd.o #103015, Ralf Habacker)
350 • Fix the build with MSVC, which regressed with the #102558 fix in
351 1.11.20. (fd.o #102558, Ralf Habacker)
355 • Simplify Windows resource embedding
356 (fd.o #103015, Simon McVittie)
358 D-Bus 1.11.20 (2017-10-03)
361 The “wraith stun” release.
363 Build-time configuration changes:
365 • The --enable-abstract-sockets and --disable-abstract-sockets options
366 no longer exist. Support for Linux's abstract AF_UNIX sockets is now
367 unconditionally enabled on Linux and disabled everywhere else.
368 (fd.o #34905, Simon McVittie)
372 • Make slower tests less likely to time out, and improve diagnostics if
373 tests do time out (fd.o #103009, Simon McVittie)
375 • On Windows, don't compile an unused stub implementation of
376 _dbus_set_signal_handler() (fd.o #103010, Simon McVittie)
380 • Be more careful to save and restore errno in POSIX async signal
381 handlers (fd.o #103010, Simon McVittie)
383 • On Windows, embed a manifest in dbus-update-activation-environment.exe
384 so that the heuristics used for UAC do not assume it needs elevated
385 privileges due to its name containing "update"
386 (fd.o #102558, Ralf Habacker)
388 • On Windows with Automake, embed version information in libdbus-1,
389 as was meant to happen in all versions since 2009
390 (fd.o #103015, Simon McVittie)
392 D-Bus 1.11.18 (2017-09-25)
395 The “vampire conquistador” release.
397 Build-time configuration changes:
399 • By default, dbus-daemon on Unix no longer checks for flag files
400 /var/run/console/${username} created by the obsolete pam_console and
401 pam_foreground PAM modules when deciding whether ${username} is
402 currently at the console. The old default behaviour can be restored
403 by specifying --with-console-auth-dir=/var/run/console in the
404 recommended Autotools build system, or
405 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
406 now deprecated, and will be removed in dbus 1.13 unless feedback via
407 fd.o #101629 indicates that this would be problematic.
408 (fd.o #101629, Simon McVittie)
410 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
411 script for Cygwin, are no longer provided in the upstream dbus
412 source. We recommend that distributors who support non-systemd service
413 management should maintain their own init scripts or other service
414 manager integration as part of their downstream packaging, similar to
415 the way Debian distributes a Debian-specific LSB init script for dbus.
417 The systemd unit continues to be maintained as part of the upstream
418 dbus source, because it receives regular testing and maintenance.
420 (fd.o #101706, Simon McVittie)
422 • The process ID file created by the system bus is no longer influenced
423 by the --with-init-scripts=redhat configure option or the presence of
424 /etc/redhat-release at build time. If your OS's init script or other
425 service management relies on the Red Hat-style pid file, it can be
426 restored by specifying --with-system-pid-file=/run/messagebus.pid at
427 configure time or using the <pidfile> directive in bus configuration.
429 Note that the upstream-supplied systemd unit runs dbus-daemon with
430 the --nopidfile option, so it does not normally write a pid file,
431 regardless of whether the OS is Red-Hat-derived or not.
433 (fd.o #101706, Simon McVittie)
437 • <allow> and <deny> rules in dbus-daemon configuration can now
438 include send_broadcast="true" or send_broadcast="false", which make
439 the rule only match broadcast signals, or only match messages that
440 are not broadcast signals, respectively.
441 (fd.o #29853, Simon McVittie)
443 • <allow> and <deny> rules can now be configured to apply only to
444 messages with or without Unix file descriptors attached. This would
445 typically be used in rules like these:
446 <allow send_destination="..." max_unix_fds="0"/>
447 <deny send_destination="..." min_unix_fds="1"/>
448 <deny receive_sender="..." min_unix_fds="1"/>
449 but can also be used to set a nonzero upper limit on the number of
451 <allow send_destination="..." max_unix_fds="4"/>
452 (fd.o #101848, Simon McVittie)
454 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
455 now respects the HOME environment variable on the client side, and
456 on the server side when the uid attempting to connect is the same
457 as the uid of the server. This allows the automated tests to pass in
458 environments where the user's "official" home directory in /etc/passwd
459 is nonexistent, such as Debian autobuilders.
460 (fd.o #101960, Simon McVittie)
464 • When parsing dbus-daemon configuration, tell Expat not to use
465 cryptographic-quality entropy as a salt for its hash tables: we trust
466 the configuration files, so we are not concerned about algorithmic
467 complexity attacks via hash table collisions. This prevents
468 dbus-daemon --system from holding up the boot process (and causing
469 early-boot system services like systemd, logind, networkd to time
470 out) on entropy-starved embedded systems.
471 (fd.o #101858, Simon McVittie)
473 • Avoid a -Werror=declaration-after-statement build failure on Solaris
474 (fd.o #102145, Alan Coopersmith)
476 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
477 to LOG_INFO, matching how we use this log level in practice
478 (fd.o #102686, Simon McVittie)
480 D-Bus 1.11.16 (2017-07-27)
483 The “south facing garden” release.
485 Build-time configuration changes:
487 • The Autotools build system now supports varying ${runstatedir}
488 independently of ${localstatedir}, if using an Autoconf version
489 that has that feature; version 2.70 will eventually have this, but
490 many Linux distributions add it to version 2.69 as a patch.
491 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
492 and runstatedir=/run. (fd.o #101569, Simon McVittie)
496 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
497 and dbus_message_iter_abandon_container_if_open() simplify the
498 single-exit-point ("goto out") style of resource cleanup. The API
499 documentation around DBusMessageIter and containers has also been
500 clarified. (fd.o #101568, Simon McVittie)
504 • Fix the implementation of re-enabling a timeout (again) so that its
505 countdown is always restarted as intended. (fd.o #95619,
508 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
509 available to all users on the system bus (fd.o #101700, Simon McVittie)
511 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
512 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
514 • dbus_message_iter_open_container() no longer leaks memory if it runs out
515 of memory. (fd.o #101568, Simon McVittie)
517 • dbus_message_append_args_valist() no longer leaks memory if given an
518 unsupported type. This situation is still considered to be a programming
519 error which needs to be corrected by the user of libdbus.
520 (fd.o #101568, Simon McVittie)
522 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
523 will no longer report that their arguments were invalid if they run out
524 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
526 • Ensure that tests fail if they would otherwise have tried to connect to
527 the real session bus (fd.o #101698, Simon McVittie)
529 • Make build-time tests cope with finding Python 3, but not Python 2
530 (fd.o #101716, Simon McVittie)
532 Internal changes relevant to dbus developers:
534 • DBusVariant is a new mechanism to copy single values from a message into
535 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
537 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
538 Logging an ERROR message does not make the process exit; the caller
539 is responsible for calling abort() or exit(), whichever is more appropriate.
540 (fd.o #101568, Simon McVittie)
542 • Better test coverage (fd.o #101568, Simon McVittie)
544 D-Bus 1.11.14 (2017-06-29)
547 The “irrational fear of bees” release.
551 • Expat >= 2.1.0 is always required
552 • libselinux >= 2.0.86 is required if SELinux support is enabled
553 • GLib >= 2.40 is required if full test coverage is enabled
555 Build-time configuration changes:
557 • We now use pkg-config to find libexpat in Autotools builds. This requires
558 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
559 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
560 itself cause compilation failures.
562 As with all pkg-config-based configure checks, you can use
563 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
564 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
565 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
568 (fd.o #69801, Simon McVittie)
570 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
571 is required due to the removal of explicit refcounting for SIDs.
572 (fd.o #100912, Laurent Bigonville)
576 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
577 as a side-effect of a sufficiently privileged process merely reading the
578 machine ID. It is no longer copied as a side-effect of reading.
579 Running dbus-uuidgen --ensure, which should be done after installing dbus,
580 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
581 former exists and the latter does not.
582 (fd.o #101257, Simon McVittie)
584 • The undocumented Verbose interface, and the GetAllMatchRules method on
585 the undocumented Stats interface, must now be used via the object path
586 /org/freedesktop/DBus. Previously, they existed on all object paths.
587 (fd.o #101257, Simon McVittie)
589 • AddMatch() with a match rule containing eavesdrop='true' will now fail
590 unless called by either the same user as the dbus-daemon, or Unix uid 0
591 (root), matching the restrictions applied to the newer BecomeMonitor()
592 method. On the session bus this has no practical effect. On the system
593 bus this will prevent certain configurations that already did not
594 work well in practice. (fd.o #101567, Simon McVittie)
598 • D-Bus Specification version 0.31
599 · Don't require implementation-specific search paths to be lowest
601 · Correct regex syntax for optionally-escaped bytes in addresses so it
602 includes hyphen-minus, forward slash and underscore as intended
603 · Describe all message bus methods in the same section
604 · Clarify the correct object path for method calls to the message bus
605 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
606 · Document that the message bus implements Introspectable, Peer and
608 · Add new Features and Interfaces properties for message bus
610 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
612 · Don't require eavesdrop='true' to be accepted from connections not
613 sufficiently privileged to use it successfully
614 · Formally deprecate eavesdropping in favour of BecomeMonitor

616 Simon McVittie, Tom Gundersen)
618 • Implement the Properties and Peer interfaces in dbus-daemon
619 (fd.o #101257, Simon McVittie)
621 • New function dbus_try_get_local_machine_id() is like
622 dbus_get_local_machine_id(), but returning a DBusError. Other code
623 that needs the machine ID will now report a recoverable error (instead
624 of logging to stderr and aborting) if no machine ID is available.
625 Generating a machine ID is still considered to be a required part of
626 installing dbus correctly. (fd.o #13194, Simon McVittie)
628 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
629 (fd.o #101315, Laurent Bigonville)
631 • Avoid deprecated API calls when using SELinux
632 (fd.o #100912, Laurent Bigonville)
634 • Switch a test from the deprecated g_test_trap_fork() to
635 g_test_trap_subprocess(), for Windows support and better robustness
636 on Unix (fd.o #101362, Simon McVittie)
638 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
639 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
640 This prevents the two files from going out of sync on stateless or live
641 images without needing to run dbus-uuidgen, and supports older D-Bus
642 implementations that do not necessarily read /etc/machine-id themselves.
643 (fd.o #101570, Simon McVittie)
645 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
646 abstract sockets. This is preferable when used with Linux containers.
647 (fd.o #101567, Simon McVittie)
651 • Fix a reference leak when blocking on a pending call on a connection
652 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
654 • Don't put timestamps in the Doxygen-generated documentation,
655 or hard-code the build directory into builds with embedded tests,
656 for reproducible builds (fd.o #100692, Simon McVittie)
658 • Fix some integration test issues (fd.o #100686, Simon McVittie)
660 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
662 • If we somehow get an autolaunch address with multiple semicolon-separated
663 components, and they don't work, don't invalidly "pile up" errors
664 (fd.o #101257, Simon McVittie)
668 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
669 (fd.o #100715, Simon McVittie)
671 D-Bus 1.11.12 (2017-04-07)
674 The “it's something humans do” release.
678 • The session dbus-daemon now supports transient .service files
679 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
680 service directories, this directory is not monitored with inotify
681 or similar, and the service files must be named exactly
682 ${bus_name}.service. (fd.o #99825, Simon McVittie)
684 • dbus can be configured with --enable-relocation when building with
685 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
686 to make the pkg-config metadata relocatable. This is useful for
687 non-standard prefixes, and in particular for Windows installations.
688 However, it is not recommended for system-wide installations into
689 /usr, because it interferes with pkg-config's ability to filter out
690 compiler default linker directories.
692 With Autotools, the default is --enable-relocation when building
693 for Windows or --disable-relocation otherwise. With CMake, the default
694 is -DDBUS_RELOCATABLE=ON.
696 (fd.o #99721; Ralf Habacker, Simon McVittie)
698 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
699 own FindDBus.cmake macros, whether dbus was compiled with Autotools
700 or with CMake. See the end of README.cmake for more information.
701 (fd.o #99721; Ralf Habacker, Simon McVittie)
705 • Always read service file directories in the intended order
706 (fd.o #99825, Simon McVittie)
708 • When tests are skipped, don't try to kill nonexistent process 0
709 (fd.o #99825, Simon McVittie)
711 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
713 • Fix a harmless read overflow and some memory leaks in a unit test
714 (fd.o #100568, Philip Withnall)
716 • Fix some typos in test code
717 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
719 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
720 in documentation (fd.o #99901, Philip Withnall)
722 • Fix and enable compiler warnings related to -Wswitch
723 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
725 • Fix writing off the end of a fd_set when testing with valgrind
726 (fd.o #99839, Philip Withnall)
728 D-Bus 1.11.10 (2017-02-16)
731 The “purple hair gives you telekinesis?” release.
735 • AppArmor support requires at least libapparmor 2.8.95, reduced
736 from 2.10 in previous versions. One test requires 2.10 and is
737 skipped if building with an older version.
741 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
742 stable and Debian testing in addition to the older Ubuntu that is
743 the default (fd.o #98889, Simon McVittie)
745 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
747 • Silence many -Wswitch-enum and -Wswitch-default warnings
748 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
750 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
751 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
753 • Install pkg-config metadata on Unix even if building with CMake
754 (fd.o #99752, Ralf Habacker)
756 • Exclude auth mechanisms from REJECTED message if they are supported
757 in the code but but configured to be disallowed (fd.o #99621,
762 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
763 allow an attacker to overwrite a file named "nonce", in a directory
764 that the user running dbus-daemon can write, with a random value
765 known only to the user running dbus-daemon. This is unlikely to be
766 exploitable in practice, particularly since the nonce-tcp transport
767 is really only useful on Windows.
769 On Unix systems we strongly recommend using only the unix: and systemd:
770 transports, together with EXTERNAL authentication. These are the only
771 transports and authentication mechanisms enabled by default.
773 (fd.o #99828, Simon McVittie)
775 • Avoid symlink attacks in the "embedded tests", which are not enabled
776 by default and should never be enabled in production builds of dbus.
777 (fd.o #99828, Simon McVittie)
779 • Fix the implementation of re-enabling a timeout so that its
780 countdown is restarted as intended, instead of continually
781 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
783 • When receiving a message with file descriptors, do not start reading
784 the beginning of the next message, so that only one such message
785 is processed at a time. In conjunction with the fix for #95619
786 this means that processes sending many file descriptors, such as
787 systemd-logind on a system that receives very rapid ssh connections,
788 are not treated as abusive and kicked off the bus. Revert the previous
789 workaround that special-cased uid 0.
790 (fd.o #95263, LP#1591411; Simon McVittie)
792 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
793 for Windows with CMake (fd.o #99586, Ralf Habacker)
795 • Do not set Unix-specific variables when targeting Windows
796 (fd.o #99586, Ralf Habacker)
798 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
799 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
801 • Use relative install locations in CMake on Unix to respect DESTDIR,
802 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
804 • Install dbus-arch-deps.h correctly when using CMake
805 (fd.o #99586, #99721; Ralf Habacker)
807 • Improve argument validation for `dbus-test-tool spam`
808 (ffd.o #99693, Coverity #54759; Philip Withnall)
810 • Don't shift by a negative integer if a hash table becomes monstrously
811 large (fd.o #99641, Coverity #54682; Philip Withnall)
813 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
814 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
816 • Remove an unnecessary NULL check
817 (fd.o #99642, Coverity #141062; Philip Withnall)
819 • Improve error handling in unit tests and dbus-send
820 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
821 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,

823 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
825 • Do not print verbose messages' timestamps to stderr if the actual message
826 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
828 D-Bus 1.11.8 (2016-11-28)
831 The “panics in the face of breakfast foods” release.
833 Build-time configuration:
835 • The new --enable-debug configure option provides an easy way to
836 enable debug symbols, disable optimization and/or enable profiling.
838 • The --enable-compile-warnings configure option can be used to control
841 • The --disable-compiler-optimisations configure option is no longer
842 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
846 • D-Bus Specification version 0.30
847 · Define the jargon term "activation" more clearly
848 · Define the jargon term "auto-starting", which is one form of activation
849 · Document the optional SystemdService key in service files
850 · Use versioned interface and bus names in most examples
851 · Clarify intended behaviour of Properties.GetAll
852 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
854 • Fix and enable a lot of compiler warnings to improve future code
855 quality. This might incidentally also fix some environment variable
857 · In particular, printf-style functions in the libdbus API are now annotated
858 with __attribute__((__format__(__printf__, *, *))) when compiling with
859 gcc or clang. This might make printf bugs in other software visible
861 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
862 Thomas Zimmermann, Simon McVittie)
864 • When running with AppArmor mediation (for example using Ubuntu's patched
865 Linux kernel), clients can no longer auto-start services unless they would
866 have been able to send the auto-starting message to the service after it
867 starts. StartServiceByName() is unaffected, and continues to be allowed by
868 default in AppArmor's <abstractions/dbus-strict> and
869 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
873 • Work around an undesired effect of the fix for CVE-2014-3637
874 (fd.o #80559), in which processes that frequently send fds, such as
875 logind during a flood of new PAM sessions, can get disconnected for
876 continuously having at least one fd "in flight" for too long;
877 dbus-daemon interprets that as a potential denial of service attack.
878 The workaround is to disable that check for uid 0 process such as
879 logind, with a message in the system log. The bug remains open while
880 we look for a more general solution.
881 (fd.o #95263, LP#1591411; Simon McVittie)
883 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
884 was disabled at compile time. That test is not expected to work
885 in that configuration. (fd.o #98665, Simon McVittie)
887 D-Bus 1.11.6 (2016-10-10)
890 The “darkly whimsical” release.
894 • Do not treat ActivationFailure message received from root-owned systemd
895 name as a format string. In principle this is a security vulnerability,
896 but we do not believe it is exploitable in practice, because only
897 privileged processes can own the org.freedesktop.systemd1 bus name, and
898 systemd does not appear to send activation failures that contain "%".
900 Please note that this probably *was* exploitable in dbus versions
901 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
902 the time was only thought to be a denial of service vulnerability
903 (CVE-2015-0245). If you are still running one of those versions,
904 patch or upgrade immediately.
906 (fd.o #98157, Simon McVittie)
910 • D-Bus Specification version 0.29
911 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
912 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
914 • Log to syslog when we exceed various anti-DoS limits, and add test
915 coverage for them (fd.o #86442, Simon McVittie)
917 • Improve syslog handling so that _dbus_warn() and similar warnings
918 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
919 and log to syslog (instead of /dev/null) when dbus-daemon is started by
920 dbus-launch. (fd.o #97009, Simon McVittie)
922 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
923 (fd.o #89011, Philip Withnall)
925 • When logging messages about service activation, mention which peer
926 requested the activation (fd.o #68212, Philip Withnall)
928 • On Linux, mention the LSM label (if available) whenever we print
929 debug information about a peer (fd.o #68212, Philip Withnall)
933 • Harden dbus-daemon against malicious or incorrect ActivationFailure
934 messages by rejecting them if they do not come from a privileged
935 process, or if systemd activation is not enabled
936 (fd.o #98157, Simon McVittie)
938 • Avoid undefined behaviour when setting reply serial number without going
939 via union DBusBasicValue (fd.o #98035, Marc Mutz)
941 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
942 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
944 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
946 D-Bus 1.11.4 (2016-08-15)
949 The “copper pickaxe” release.
953 • Building from git (but not from tarballs) now requires
954 macros from the GNU Autoconf Archive, for example the autoconf-archive
955 package in Debian or Fedora derivatives.
957 Build-time configuration:
959 • The option to enable coverage instrumentation has changed from
960 --enable-compiler-coverage to --enable-code-coverage.
964 • D-Bus Specification version 0.28
965 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
967 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
968 minimizing failed connections under heavy load
969 (fd.o #95264, Lennart Poettering)
971 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
973 • Use the same regression tests for subprocess starting on Unix and Windows
974 (fd.o #95191, Ralf Habacker)
976 • Print timestamps and thread IDs in verbose messages
977 (fd.o #95191, Ralf Habacker)
979 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
980 pointing to /dev/null (fd.o #97008, Simon McVittie)
982 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
983 (fd.o #88922, Thomas Zimmermann)
987 • On Windows, fix a memory leak in replacing the installation prefix
988 (fd.o #95191, Ralf Habacker)
990 • On Linux, when dbus-daemon is run with reduced susceptibility to the
991 OOM killer (typically via systemd), do not let child processes inherit
992 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
994 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
995 even if a parent process incorrectly starts them with stdin, stdout
996 and/or stderr closed (fd.o #97008, Simon McVittie)
998 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
999 contains a semicolon (fd.o #94746, Thiago Macieira)
1001 • Fix memory leaks and thread safety in subprocess starting on Windows
1002 (fd.o #95191, Ralf Habacker)
1004 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
1005 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
1007 • In tests that exercise correct handling of crashing D-Bus services,
1008 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
1010 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
1012 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
1013 in some test cases (fd.o #93909, Nick Lewycky)
1015 • Add assertions to reassure a static analysis tool
1016 (fd.o #93210, Deepika Aggarwal)
1018 • Be explicit about enum comparison when loading XML
1019 (fd.o #93205, Deepika Aggarwal)
1021 • update-activation-environment: produce better diagnostics on error
1022 (fd.o #96653, Simon McVittie)
1024 • Avoid various compiler warnings with gcc 6
1025 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
1027 • On Unix when configured to use the system log, report as "dbus-daemon",
1028 not as "dbus" (fd.o #97009, Simon McVittie)
1030 • During unit tests, reduce the amount we write to the system log
1031 (fd.o #97009, Simon McVittie)
1033 D-Bus 1.11.2 (2016-03-07)
1036 The “pneumatic drill vs. Iron Maiden” release.
1040 • Enable "large file support" on systems where it exists: dbus-daemon
1041 is not expected to open large files, but it might need to stat files
1042 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
1044 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
1045 which might result in a pedantic C compiler not copying the entire contents
1046 of a DBusMessageIter; statically assert that this is not an ABI change
1047 in practice (fd.o #94136, Simon McVittie)
1049 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
1050 (fd.o #94244, Dmitri Iouchtchenko)
1052 • Correctly report test failures in C tests from run-test.sh
1053 (fd.o #93379; amit tewari, Simon McVittie)
1055 • When tests are enabled, run all the marshal-validate tests, not just
1056 the even-numbered ones (fd.o #93908, Nick Lewycky)
1058 • Correct the expected error from one marshal-validate test, which was
1059 previously not run due to the above bug (fd.o #93908, Simon McVittie)
1061 • Fix compilation under CMake when embedded tests are disabled
1062 (fd.o #94094, eric.hyer)
1066 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
1067 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
1069 • When building with CMake, use the same gcc/clang warnings as under Autotools,
1070 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
1072 • test/name-test: make C tests produce TAP output and run them directly, not
1073 via run-test.sh (fd.o #92899, Simon McVittie)
1075 • Under CMake when cross-compiling for Windows on Unix, run the tests
1076 under Wine even if binfmt_misc support is not available
1077 (fd.o #88966, Ralf Habacker)
1079 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
1080 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
1082 • Factor out some functions that will be needed in future for a Windows
1083 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
1085 D-Bus 1.11.0 (2015-12-02)
1088 The “peppermint deer” release.
1092 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
1093 C99 constants such as PRId64 and PRIu64.
1097 • D-Bus Specification version 0.27
1098 · Specify that services should not reply if NO_REPLY_EXPECTED was used
1099 (fd.o #75749, Lars Uebernickel)
1101 • Add a script to do continuous-integration builds, and metadata to run it
1102 on travis-ci.org. To use this, clone the dbus git repository on GitHub
1103 and set it up with travis-ci.org; the only special setting needed is
1104 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
1106 • If dbus-daemon is run with --systemd-activation, do not require
1107 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
1111 • Re-order dbus-daemon startup so that on SELinux systems, the thread
1112 that reads AVC notifications retains the ability to write to the
1113 audit log (fd.o #92832, Laurent Bigonville)
1115 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
1117 • When using the Monitoring interface, match messages' destinations
1118 (fd.o #92074, Simon McVittie)
1120 • On Linux with systemd, stop installing a reference to the obsolete
1121 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
1124 • On Windows, when including configuration files with <include> or
1125 <includedir>, apply the same relocation as for the Exec paths
1126 in .service files (fd.o #92028, Simon McVittie)
1128 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
1130 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
1132 D-Bus 1.10.6 (2015-12-01)
1135 The “marzipan beetles” release.
1139 • On Unix when running tests as root, don't assert that root and
1140 the dbus-daemon user can still call UpdateActivationEnvironment;
1141 assert that those privileged users can call BecomeMonitor instead
1142 (fd.o #93036, Simon McVittie)
1144 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
1147 • On Windows Autotools builds, don't run tests that rely on
1148 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
1150 D-Bus 1.10.4 (2015-11-17)
1153 The “Frostburn Canyon” release.
1157 • GetConnectionCredentials, GetConnectionUnixUser and
1158 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
1159 will now return details of the dbus-daemon itself. This is required
1160 to be able to call SetEnvironment on systemd.
1161 (fd.o #92857, Jan Alexander Steffens)
1165 • Make UpdateActivationEnvironment always fail with AccessDenied on the
1166 system bus. Previously, it was possible to configure it so root could
1167 call it, but the environment variables were not actually used,
1168 because the launch helper would discard them.
1169 (fd.o #92857, Jan Alexander Steffens)
1171 • On Unix with --systemd-activation on a user bus, make
1172 UpdateActivationEnvironment pass on its arguments to systemd's
1173 SetEnvironment method, solving inconsistency between the environments
1174 used for traditional activation and systemd user-service activation.
1175 (fd.o #92857, Jan Alexander Steffens)
1177 • On Windows, don't crash if <syslog/> or --syslog is used
1178 (fd.o #92538, Ralf Habacker)
1180 • On Windows, fix a memory leak when setting a DBusError from a Windows
1181 error (fd.o #92721, Ralf Habacker)
1183 • On Windows, don't go into infinite recursion if we abort the process
1184 with backtraces enabled (fd.o #92721, Ralf Habacker)
1186 • Fix various failing tests, variously on Windows and cross-platform:
1187 · don't test system.conf features (users, groups) that only make sense
1188 on the system bus, which is not supported on Windows
1189 · don't call _dbus_warn() when we skip a test, since it is fatal
1190 · fix computation of expected <standard_session_servicedirs/>
1191 · when running TAP tests, translate newlines to Unix format, fixing
1192 cross-compiled tests under Wine on Linux
1193 · don't stress-test refcounting under Wine, where it's really slow
1194 · stop assuming that a message looped-back to the test will be received
1196 · skip some system bus tests on Windows since they make no sense there
1197 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
1199 D-Bus 1.10.2 (2015-10-26)
1202 The “worst pies in London” release.
1206 • Correct error handling for activation: if there are multiple attempts
1207 to activate the same service and it fails immediately, the first attempt
1208 would get the correct reply, but the rest would time out. We now send
1209 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
1211 • If BecomeMonitor is called with a syntactically invalid match rule,
1212 don't crash with an assertion failure, fixing a regression in 1.9.10.
1213 This was not exploitable as a denial of service, because the check
1214 for a privileged user is done first. (fd.o #92298, Simon McVittie)
1216 • On Linux with --enable-user-session, add the bus address to the
1217 environment of systemd services for better backwards compatibility
1218 (fd.o #92612, Jan Alexander Steffens)
1220 • On Windows, fix the logic for replacing the installation prefix
1221 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
1223 • On Windows, if installed in the conventional layout with ${prefix}/etc
1224 and ${prefix}/share, use relative paths between bus configuration files
1225 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
1227 • Make more of the regression tests pass in Windows builds (fd.o #92538,
1230 D-Bus 1.10.0 (2015-08-25)
1235 This is a new stable branch, recommended for use in OS distributions.
1239 • distribute test/tap-test.sh.in, even if the tarball was built without
1240 tests enabled (fd.o #91684, Simon McVittie)
1241 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
1243 Summary of major changes since 1.8.0:
1245 • The basic setup for the well-known system and session buses is
1246 now done in read-only files in ${datadir} (normally /usr/share).
1247 See the NEWS entry for 1.9.18 for details.
1249 • AppArmor integration has been merged, with features similar to the
1250 pre-existing SELinux integration. It is mostly compatible with the
1251 patches previously shipped by Ubuntu, with one significant change:
1252 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
1253 by GetConnectionCredentials and was not included.
1255 • The --enable-user-session configure option can be enabled
1256 by OS integrators intending to use systemd to provide a session bus
1257 per user (in effect, treating all concurrent graphical and non-graphical
1258 login sessions as one large session).
1260 • The new listenable address mode "unix:runtime=yes" listens on
1261 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
1262 user session. libdbus and "dbus-launch --autolaunch" will connect to
1263 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
1266 • All executables are now dynamically linked to libdbus-1.
1267 Previously, some executables, most notably dbus-daemon, were statically
1268 linked to a specially-compiled variant of libdbus. This results in
1269 various private functions in the _dbus namespace being exposed by the
1270 shared library. These are not API, and must not be used outside
1271 the dbus source tree.
1273 • On platforms with ELF symbol versioning, all public symbols
1274 are versioned LIBDBUS_1_3.
1278 • org.freedesktop.DBus.GetConnectionCredentials returns
1279 LinuxSecurityLabel where supported
1280 • org.freedesktop.DBus.Monitoring interface (privileged)
1281 · BecomeMonitor method supersedes match rules with eavesdrop=true,
1282 which are now deprecated
1283 • org.freedesktop.DBus.Stats interface (semi-privileged)
1284 · now enabled by default
1285 · new GetAllMatchRules method
1286 • org.freedesktop.DBus.Verbose interface (not normally compiled)
1287 · toggles the effect of DBUS_VERBOSE
1292 • dbus-update-activation-environment
1294 New optional dependencies:
1296 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
1297 • Complete documentation requires Ducktype and yelp-tools
1298 • Full test coverage requires GLib 2.36 and PyGI
1299 • AppArmor integration requires libapparmor and optionally libaudit
1301 Dependencies removed:
1305 D-Bus 1.9.20 (2015-08-06)
1308 The “Remember Tomorrow” release.
1310 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
1315 • Don't second-guess what the ABI of poll() is, allowing it to be used
1316 on Integrity RTOS and other unusual platforms (fd.o #90314;
1317 Rolland Dudemaine, Simon McVittie)
1319 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
1320 both enabled (fd.o #89225, Simon McVittie)
1322 • Log audit events for AppArmor/SELinux policy violations whenever
1323 we have CAP_AUDIT_WRITE, even if not the system bus
1324 (fd.o #83856, Laurent Bigonville)
1326 D-Bus 1.9.18 (2015-07-21)
1329 The “Pirate Elite” release.
1331 Configuration changes:
1333 • The basic setup for the well-known system and session buses is now done
1334 in read-only files in ${datadir}, moving a step closer to systems
1335 that can operate with an empty /etc directory. In increasing order
1338 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
1339 the default message policies.
1340 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
1341 dbus still installs a trivial version of each, for documentation
1342 purposes; putting configuration directives in these files is deprecated.
1343 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
1344 to install "drop-in" configuration snippets (any packages
1345 using those directories should explicitly depend on at least this
1347 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
1348 or third-party software to install "drop-in" configuration snippets
1349 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
1352 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
1353 and "s*" refers to either system or session as appropriate.
1355 (fd.o #89280, Dimitri John Ledkov)
1359 • Fix a memory leak when GetConnectionCredentials() succeeds
1360 (fd.o #91008, Jacek Bukarewicz)
1362 • Ensure that dbus-monitor does not reply to messages intended for others,
1363 resulting in its own disconnection (fd.o #90952, Simon McVittie)
1365 D-Bus 1.9.16 (2015-05-14)
1368 The “titanium barns” release.
1372 • Automake 1.13 is now required when compiling from git or modifying
1377 • On Unix platforms, change the default configuration for the session bus
1378 to only allow EXTERNAL authentication (secure kernel-mediated
1379 credentials-passing), as was already done for the system bus.
1381 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
1382 unpredictable pseudo-random numbers.
1384 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
1385 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1386 NFS or similar, you will need to reconfigure the session bus to accept
1387 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1390 (fd.o #90414, Simon McVittie)
1392 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1393 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1394 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1395 occurs, instead of silently falling back to low-entropy pseudorandom
1396 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1400 • Add dbus_message_iter_get_element_count()
1401 (fd.o #30350; Christian Dywan, Simon McVittie)
1403 • Introduce new internal DBusSocket and DBusPollable types so we can
1404 stop treating the Windows SOCKET type as if it was int. DBusSocket
1405 is specifically a socket, cross-platform. DBusPollable is whatever
1406 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1407 (fd.o #89444; Ralf Habacker, Simon McVittie)
1409 • All regression tests now output TAP <https://testanything.org/>
1410 (fd.o #89846, Simon McVittie)
1412 • Internal APIs consistently use signed values for timestamps
1413 (fd.o #18494, Peter McCurdy)
1415 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1416 (fd.o #88812, Simon McVittie)
1418 • Clean up a lot of compiler warnings
1419 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1423 • Add locking to DBusCounter's reference count and notify function
1424 (fd.o #89297, Adrian Szyndela)
1426 • Ensure that DBusTransport's reference count is protected by the
1427 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1429 • Correctly release DBusServer mutex before early-return if we run out
1430 of memory while copying authentication mechanisms (fd.o #90021,
1433 • Make dbus-test-tool and dbus-update-activation-environment portable
1434 to Windows (fd.o #90089, Ralf Habacker)
1436 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1437 Ralf Habacker, Simon McVittie)
1439 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1442 • Clean up some memory and fd leaks in test code and tools
1443 (fd.o #90021, Ralf Habacker)
1445 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1446 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1448 • CMake generates a versioned shared library even if the revision is 0,
1449 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1451 D-Bus 1.9.14 (2015-03-02)
1454 The “don't stand in the poison cloud” release.
1458 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1459 were previously linked to a static version of libdbus.
1461 • The tests no longer require dbus-glib in order to exercise the libdbus
1462 shared library; they are always linked to libdbus now.
1464 Build-time configuration:
1466 • The new --enable-user-session option, off by default, can be enabled
1467 by OS integrators intending to use systemd to provide a session bus
1468 per user (in effect, treating all concurrent graphical and non-graphical
1469 login sessions as one large session)
1473 • All executables are now linked dynamically to libdbus.
1474 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1476 • On platforms that support them (GNU libc and possibly others),
1477 libdbus now has versioned symbols for its public API.
1478 All public symbols (visible in the header files) are currently
1479 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1480 dbus_internal have a version that changes with each release, and
1481 must not be used by applications. (also fd.o #83115)
1483 • New listenable address mode "unix:runtime=yes" which listens on
1484 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1485 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1487 • Add optional systemd units for a per-user bus listening on
1488 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1490 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1491 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1494 • New dbus-update-activation-environment tool uploads environment
1495 variables to "dbus-daemon --session" and optionally "systemd --user",
1496 primarily as a way to keep the per-user bus compatible with
1497 distributions' existing X11 login scripts (also fd.o #61301)
1499 • <includedir/> elements in dbus-daemon configuration are now silently
1500 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1502 • Add microsecond-resolution timestamps to the default output of
1503 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1507 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1508 (fd.o #89222, Simon McVittie)
1510 D-Bus 1.9.12 (2015-02-19)
1513 The “monster lasagna” release.
1517 • Ducktype and yelp-tools are now required to build complete documentation
1518 (they are optional for normal builds).
1522 • D-Bus Specification version 0.26
1523 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1524 · document the BecomeMonitor method
1526 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1527 (fd.o #89041; Tyler Hicks, Simon McVittie)
1529 • On Linux, add support for AppArmor mediation of message sending and
1530 receiving and name ownership (paralleling existing SELinux mediation
1531 support), and eavesdropping (a new check, currently AppArmor-specific)
1532 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1534 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1535 that have printable ASCII contents; we previously only did this for
1536 unterminated bytestrings (fd.o #89109, Simon McVittie)
1538 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1540 • On Windows, add WindowsSID to GetConnectionCredentials
1541 (fd.o #54445, Ralf Habacker)
1543 • Improve clarity of dbus-monitor --profile output and add more columns
1544 (fd.o #89165, Ralf Habacker)
1546 • Add a man page for dbus-test-tool, and build it under CMake as well
1547 as Autotools (fd.o#89086, Simon McVittie)
1549 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1550 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1551 (fd.o #88896, Ralf Habacker)
1555 • Reduce the number of file descriptors used in the fd-passing test,
1556 avoiding failure under the default Linux fd limit, and automatically
1557 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1559 D-Bus 1.9.10 (2015-02-09)
1562 The “sad cyborgs” release.
1564 Security fixes merged from 1.8.16:
1566 • Do not allow non-uid-0 processes to send forged ActivationFailure
1567 messages. On Linux systems with systemd activation, this would
1568 allow a local denial of service: unprivileged processes could
1569 flood the bus with these forged messages, winning the race with
1570 the actual service activation and causing an error reply
1571 to be sent back when service auto-activation was requested.
1572 This does not prevent the real service from being started,
1573 so the attack only works while the real service is not running.
1574 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1578 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1579 similar tools receive messages without altering the security properties
1580 of the system bus, by calling the new BecomeMonitor method on a
1581 private connection. This bypasses the normal <allow> and <deny> rules
1582 entirely, so to preserve normal message-privacy assumptions, only root
1583 is allowed to do this on the system bus. Restricted environments,
1584 such as Linux with LSMs, should lock down access to the Monitoring
1585 interface. (fd.o #46787, Simon McVittie)
1587 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1588 dbus-daemon supports it and access permissions allow it.
1589 It still supports the previous approach ("eavesdropping" match rules)
1590 for compatibility with older bus daemons. (fd.o #46787, Simon)
1592 • dbus-monitor can now log the message stream as binary data for later
1593 analysis, with either no extra framing beyond the normal D-Bus headers,
1594 or libpcap-compatible framing treating each D-Bus message
1595 as a captured packet. (fd.o #46787, Simon)
1599 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1601 • On Unix, forcibly terminate regression tests after 60 seconds to
1602 prevent them from blocking continuous integration frameworks
1603 (fd.o #46787, Simon)
1605 D-Bus 1.9.8 (2015-02-03)
1608 The “all the types of precipitation” release.
1612 • full test coverage now requires GLib 2.36
1613 • full test coverage now requires PyGI (PyGObject 3,
1614 "import gi.repository.GObject") instead of the
1615 obsolete PyGObject 2 ("import gobject")
1619 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1621 • better regression test coverage, including systemd activation
1622 (fd.o #57952, #88810; Simon McVittie)
1626 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1627 turned off (fd.o #88808, Simon McVittie)
1629 • TCP sockets on Windows no longer fail to listen approximately 1 time
1630 in 256, caused by a logic error that should have always made it fail but
1631 was mitigated by incorrect endianness for the port number
1632 (fd.o #87999, Ralf Habacker)
1634 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1636 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1637 previous 64, completing a previous fix which only worked under
1638 Autotools (fd.o #71297, Ralf Habacker)
1640 • on Windows, if the IP family is unspecified only use IPv4,
1641 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1643 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1645 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1647 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1650 D-Bus 1.9.6 (2015-01-05)
1653 The “I do have a bread knife” release.
1657 • Do not allow calls to UpdateActivationEnvironment from uids other than
1658 the uid of the dbus-daemon. If a system service installs unsafe
1659 security policy rules that allow arbitrary method calls
1660 (such as CVE-2014-8148) then this prevents memory consumption and
1661 possible privilege escalation via UpdateActivationEnvironment.
1663 We believe that in practice, privilege escalation here is avoided
1664 by dbus-daemon-launch-helper sanitizing its environment; but
1665 it seems better to be safe.
1667 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1668 on object paths other than /org/freedesktop/DBus. Some system services
1669 install unsafe security policy rules that allow arbitrary method calls
1670 to any destination, method and interface with a specified object path;
1671 while less bad than allowing arbitrary method calls, these security
1672 policies are still harmful, since dbus-daemon normally offers the
1673 same API on all object paths and other system services might behave
1678 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1679 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1681 D-Bus 1.9.4 (2014-11-24)
1684 The “extra-sturdy caramel” release.
1688 • Partially revert the CVE-2014-3639 patch by increasing the default
1689 authentication timeout on the system bus from 5 seconds back to 30
1690 seconds, since this has been reported to cause boot regressions for
1691 some users, mostly with parallel boot (systemd) on slower hardware.
1693 On fast systems where local users are considered particularly hostile,
1694 administrators can return to the 5 second timeout (or any other value
1695 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1698 <limit name="auth_timeout">5000</limit>
1701 (fd.o #86431, Simon McVittie)
1703 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1704 (fd.o #86431, Simon McVittie)
1706 • Send back an AccessDenied error if the addressed recipient is not allowed
1707 to receive a message (and in builds with assertions enabled, don't
1708 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1710 D-Bus 1.9.2 (2014-11-10)
1713 The “structurally unsound flapjack” release.
1717 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1718 so that CVE-2014-3636 part A cannot exhaust the system bus'
1719 file descriptors, completing the incomplete fix in 1.8.8.
1720 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1724 • D-Bus Specification version 0.25
1725 · new value 'const' for EmitsChangedSignal annotation
1726 (fd.o #72958, Lennart Poettering)
1727 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1728 (fd.o #83449; Lennart Poettering, Simon McVittie)
1729 · annotate table of types with reserved/basic/container, and for
1730 basic types, fixed/string-like

1733 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1734 (fd.o #83449, Simon McVittie)
1736 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1737 useful for debugging and performance testing:
1738 · dbus-test-tool spam: send repeated messages
1739 · dbus-test-tool echo: send an empty reply for all method calls
1740 · dbus-test-tool black-hole: do not reply to method calls

1749 • Document the central assumption that makes our use of credentials-passing
1750 secure (fd.o #83499, Simon McVittie)
1752 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1753 and add some links to GDBus and QtDBus documentation (fd.o #25140,

1765 (fd.o #85563, Patrick Welche)
1767 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1769 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1770 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1772 • Do not fail the tests if a parent process has leaked non-close-on-exec
1773 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1775 • Do not fail the tests on Unix platforms with incomplete
1776 credentials-passing support, but do fail if we can't pass credentials
1777 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1778 (fd.o #69702, Simon McVittie)
1780 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1781 when building with cmake, and expand test coverage there
1782 (fd.o #73689; Ralf Habacker, Simon McVittie)
1784 D-Bus 1.9.0 (2014-10-01)
1787 The “tiered cheeses” release.
1791 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1792 requires either the libsystemd or libsd-daemon shared library, dropping the
1793 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1795 Build-time configuration changes:
1797 • The Stats interface is now enabled by default, and locked-down to
1798 root-only on the system bus. Configure with --disable-stats
1799 to disable it altogether on memory- or disk-constrained systems,
1800 or see ${docdir}/examples/ to open it up to non-root users on the
1801 system bus or restrict access on the session bus.
1802 (fd.o #80759; Simon McVittie, Alban Crequy)
1804 • The CMake build system now builds the same shared library name as Autotools
1805 on at least Linux and Windows:
1806 - on Linux (and perhaps other Unix platforms), it previously built
1807 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1808 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1809 - on Windows, it previously built either libdbus-1.dll (release) or
1810 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1811 libdbus-1.dll for compatibility with older applications.

1847 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
1848 in ps(1) (fd.o #69716, Chengwei Yang)
1850 • avoid calling poll() with timeout < -1, which is considered invalid
1851 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
1853 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
1854 (like Mac OS X 10.6), or available in libc but unsupported by the kernel

1868 • Remove some LGPL code from the Windows dbus-daemon
1869 (fd.o #57272, Ralf Habacker)
1871 D-Bus 1.8.8 (2014-09-16)
1874 The "smashy smashy egg man" release.
1878 • Do not accept an extra fd in the padding of a cmsg message, which
1879 could lead to a 4-byte heap buffer overrun.
1880 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1882 • Reduce default for maximum Unix file descriptors passed per message
1883 from 1024 to 16, preventing a uid with the default maximum number of
1884 connections from exhausting the system bus' file descriptors under
1885 Linux's default rlimit. Distributors or system administrators with a
1886 more restrictive fd limit may wish to reduce these limits further.
1888 Additionally, on Linux this prevents a second denial of service
1889 in which the dbus-daemon can be made to exceed the maximum number
1890 of fds per sendmsg() and disconnect the process that would have
1892 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1894 • Disconnect connections that still have a fd pending unmarshalling after
1895 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1896 removing the possibility of creating an abusive connection that cannot be
1897 disconnected by setting up a circular reference to a connection's
1899 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1901 • Reduce default for maximum pending replies per connection from 8192 to 128,
1902 mitigating an algorithmic complexity denial-of-service attack
1903 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1905 • Reduce default for authentication timeout on the system bus from
1906 30 seconds to 5 seconds, avoiding denial of service by using up
1907 all unauthenticated connection slots; and when all unauthenticated
1908 connection slots are used up, make new connection attempts block
1909 instead of disconnecting them.
1910 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1914 • Check for libsystemd from systemd >= 209, falling back to
1915 the older separate libraries if not found (Umut Tezduyar Lindskog,
1918 • On Linux, use prctl() to disable core dumps from a test executable
1919 that deliberately raises SIGSEGV to test dbus-daemon's handling
1920 of that condition (fd.o #83772, Simon McVittie)
1922 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
1925 • Improve documentation for running tests on Windows (fd.o #41252,
1928 D-Bus 1.8.6 (2014-06-02)
1933 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1934 the message. This prevents an attack in which a malicious client can
1935 make dbus-daemon disconnect a system service, which is a local
1937 (fd.o #80163, CVE-2014-3532; Alban Crequy)
1939 • Track remaining Unix file descriptors correctly when more than one
1940 message in quick succession contains fds. This prevents another attack
1941 in which a malicious client can make dbus-daemon disconnect a system

1948 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
1949 attach to a session, kill the dbus-daemon as intended
1950 (fd.o #74698, Роман Донченко)
1952 D-Bus 1.8.4 (2014-06-10)
1957 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1958 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1959 Additionally, in highly unusual environments the same flaw could lead to
1960 a side channel between processes that should not be able to communicate.
1961 (CVE-2014-3477, fd.o #78979)
1963 D-Bus 1.8.2 (2014-04-30)
1966 The “nobody wants red” release.
1970 • in the CMake build system, add some hints for Linux users cross-compiling
1971 Windows D-Bus binaries to be able to run tests under Wine
1972 (fd.o #41252, Ralf Habacker)
1974 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
1978 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
1979 to /var/lib/dbus/machine-id instead of generating an entirely new ID
1980 (fd.o #77941, Simon McVittie)
1982 • if dbus-launch receives an X error very quickly, do not kill
1983 unrelated processes (fd.o #74698, Роман Донченко)
1985 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
1986 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
1988 • cope with \r\n newlines in regression tests, since on Windows,
1989 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
1991 D-Bus 1.8.0 (2014-01-20)
1994 The “Wolverine distrusts my printer” release.
1996 This starts a new stable branch. The 1.6.x branch is now considered to be
1997 outdated, and will only receive fixes for serious bugs such as security
1998 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1999 are unlikely to get any more releases, but if distributors still need to
2000 support them, please share security patches via upstream.
2002 Summary of changes since 1.6.x:
2004 • libdbus always behaves as if dbus_threads_init_default() had been called
2005 (thread-safety by default)
2006 • new dbus-run-session tool, replacing certain misuses of dbus-launch
2007 • dbus-monitor can talk to outdated versions of dbus-daemon again
2008 • new org.freedesktop.DBus.GetConnectionCredentials method
2009 • GetConnectionUnixProcessID also works correctly on Windows, returning
2010 the Windows process ID
2011 • GetConnectionWindowsSID returns the correct SID on Windows
2012 • expat is required, libxml2 can no longer be used as a substitute
2013 • the userDB cache is required, and cannot be disabled
2014 • a 64-bit integer type (either int, long, long long or _int64) is required
2015 • better systemd-journald integration on Linux
2016 • fixed long-standing fd and array leaks when failing to parse a message
2017 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
2018 when using certain object-path allocation patterns, notably in Avahi
2019 • better defaults for Windows support
2020 • better CMake support
2021 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
2022 • the source language for the man pages is now Docbook XML
2024 Enhancements since 1.7.10:
2026 • Enhance the CMake build system to check for GLib and compile/run
2027 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
2031 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
2034 • fix compilation of systemd journal support on older systemd versions where
2035 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
2037 • fix compilation on older MSVC versions by including stdlib.h
2038 (fd.o #73455, Ralf Habacker)
2040 • Allow <allow_anonymous/> to appear in an included configuration file
2041 (fd.o #73475, Matt Hoosier)
2043 Test behaviour changes since 1.7.10:
2045 • If the tests crash with an assertion failure, they no longer default to
2046 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
2047 environment if you want the old behaviour.
2049 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
2050 can be run with an external dbus-daemon by setting
2051 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
2052 an unusually-configured dbus-daemon are skipped.
2054 D-Bus 1.7.10 (2014-01-06)
2057 The “weighted companion cube” release.
2059 This is a release candidate for D-Bus 1.8.
2061 D-Bus Specification 0.23:
2063 • don't require messages with no INTERFACE to be dispatched
2064 (fd.o #68597, Simon McVittie)
2066 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
2069 • define "listenable" and "connectable" addresses, and discuss
2070 the difference (fd.o #61303, Simon McVittie)
2074 • support printing Unix file descriptors in dbus-send, dbus-monitor
2075 (fd.o #70592, Robert Ancell)
2077 • don't install systemd units if --disable-systemd is given
2078 (fd.o #71818, Chengwei Yang)
2082 • don't leak memory on out-of-memory while listing activatable or
2083 active services (fd.o #71526, Radoslaw Pajak)
2085 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
2087 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
2089 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
2090 and DBUS__SEND_MSG are numerically equal to their values in the
2091 reference policy (fd.o #88719, osmond sun)
2093 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
2094 (fd.o #71366, Matt Fischer)
2096 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
2097 winsock2.h (fd.o #71405, Matt Fischer)
2099 • do not return failure from _dbus_read_nonce() with no error set,
2100 preventing a potential crash (fd.o #72298, Chengwei Yang)
2102 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
2103 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
2105 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
2106 which doesn't do anything anyway on at least Linux and FreeBSD
2107 (fd.o #69492, Simon McVittie)
2109 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
2110 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
2111 for credentials more correctly (fd.o #69492, Simon McVittie)
2113 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
2114 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
2117 • refresh cached policy rules for existing connections when bus
2118 configuration changes (fd.o #39463, Chengwei Yang)
2120 D-Bus 1.7.8 (2013-11-01)
2123 The “extreme hills” release.
2127 • If systemd support is enabled, libsystemd-journal is now required.
2131 • When activating a non-systemd service under systemd, annotate its
2132 stdout/stderr with its bus name in the Journal. Known limitation:
2133 because the socket is opened before forking, the process will still be
2134 logged as if it had dbus-daemon's process ID and user ID.
2135 (fd.o #68559, Chengwei Yang)
2137 • Document more configuration elements in dbus-daemon(1)
2138 (fd.o #69125, Chengwei Yang)
2142 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
2143 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
2145 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
2146 disallowed method calls to the audit log, fixing a regression in 1.7.6
2147 (fd.o #49062, Colin Walters)
2149 • path_namespace='/' in match rules incorrectly matched nothing; it
2150 now matches everything. (fd.o #70799, Simon McVittie)
2152 D-Bus 1.7.6 (2013-10-09)
2155 The “CSI Shrewsbury” release.
2157 Build-time configuration changes:
2159 • Directory change notification via dnotify on Linux is no longer
2160 supported; it hadn't compiled successfully since 2010 in any case.
2161 If you don't have inotify (Linux) or kqueue (*BSD), you will need
2162 to send SIGHUP to the dbus-daemon when its configuration changes.
2163 (fd.o #33001, Chengwei Yang)
2165 • Compiling with --disable-userdb-cache is no longer supported;
2166 it didn't work since at least 2008, and would lead to an extremely
2167 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
2170 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
2171 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
2172 with the Autotools build system. (fd.o #66142, Chengwei Yang)
2174 • --with-valgrind=auto enables Valgrind instrumentation if and only if
2175 valgrind headers are available. The default is still --with-valgrind=no.
2176 (fd.o #56925, Simon McVittie)
2180 • Platforms with no 64-bit integer type are no longer supported.
2181 (fd.o #65429, Simon McVittie)
2183 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
2185 • Full test coverage no longer requires dbus-glib, although the tests do not
2186 exercise the shared library (only a static copy) if dbus-glib is missing.
2187 (fd.o #68852, Simon McVittie)
2191 • D-Bus Specification 0.22
2192 · Document GetAdtAuditSessionData() and
2193 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
2194 · Fix example .service file (fd.o #66481, Chengwei Yang)
2195 · Don't claim D-Bus is "low-latency" (lower than what?), just
2196 give factual statements about it supporting async use
2197 (fd.o #65141, Justin Lee)
2198 · Document the contents of .service files, and the fact that
2199 system services' filenames are constrained
2200 (fd.o #66608; Simon McVittie, Chengwei Yang)
2202 • Be thread-safe by default on all platforms, even if
2203 dbus_threads_init_default() has not been called. For compatibility with
2204 older libdbus, library users should continue to call
2205 dbus_threads_init_default(): it is harmless to do so.
2206 (fd.o #54972, Simon McVittie)
2208 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
2210 • New API: dbus_setenv(), a simple wrapper around setenv().
2211 Note that this is not thread-safe. (fd.o #39196, Simon)
2213 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
2214 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
2215 (connect to a given bus, like dbus-monitor --address=ADDRESS).
2216 dbus-send --address still exists for backwards compatibility,
2217 but is no longer documented. (fd.o #48816, Andrey Mazo)
2220 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
2225 • Avoid an infinite busy-loop if a signal interrupts waitpid()
2226 (fd.o #68945, Simon McVittie)
2228 • Clean up memory for parent nodes when objects are unexported
2229 (fd.o #60176, Thomas Fitzsimmons)
2231 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
2232 documented. Previously, it assumed its second parameter was TRUE.
2233 (fd.o #69165, Chengwei Yang)
2235 • Escape addresses containing non-ASCII characters correctly
2236 (fd.o #53499, Chengwei Yang)
2238 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
2240 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
2241 (fd.o #65923, Chengwei Yang)
2243 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
2244 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
2246 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
2247 that was never va_start()ed (fd.o #66300, Chengwei Yang)
2249 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
2251 • fix a regression test on platforms with strict alignment (fd.o #67279,
2254 • Avoid calling function parameters "interface" since certain Windows headers
2255 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
2257 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
2259 • Various thread-safety improvements to static variables (fd.o #68610,
2262 • Make "make -j check" work (fd.o #68852, Simon McVittie)
2264 • Fix a NULL pointer dereference on an unlikely error path
2265 (fd.o #69327, Sviatoslav Chagaev)
2267 • Improve valgrind memory pool tracking (fd.o #69326,
2270 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
2273 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
2274 (fd.o #66107, Chengwei Yang)
2277 · If accept4() fails with EINVAL, as it can on older Linux kernels
2278 with newer glibc, try accept() instead of going into a busy-loop.
2279 (fd.o #69026, Chengwei Yang)

2325 The “but is your thread-safety thread-safe?” release.
2329 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
2330 of service for system services. Vulnerability reported by Alexandru Cornea.
2335 • The Windows version of libdbus now contains a C++ source file, used
2336 to provide global initialization when the library is loaded.
2337 gcc (mingw*) users should ensure that g++ is also installed.
2339 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
2340 and was never the recommended option) has been removed. Expat is now a
2345 • It should now be safe to call dbus_threads_init_default() from any thread,
2346 at any time. Authors of loadable modules and plugins that use libdbus
2347 should consider doing so during initialization.
2348 (fd.o #54972, Simon McVittie)
2350 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
2354 · dbus-run-session: experimental new tool to start a temporary D-Bus
2355 session, e.g. for regression tests or a text console, replacing
2356 certain uses of dbus-launch which weren't really correct
2357 (fd.o #39196, Simon)
2361 • In dbus-daemon, don't crash if a .service file starts with key=value

2366 on a platform not defining LOG_PERROR, such as Solaris or QNX.
2367 This regressed in 1.7.0. (Simon)
2368 · Fix an assertion failure if we try to activate systemd services before
2369 systemd connects to the bus (fd.o #50199, Chengwei Yang)
2370 · Avoid compiler warnings for ignoring the return from write()
2374 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/

2429 The "Disingenuous Assertions" release.
2431 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
2432 remains the recommended version for long-term-supported distributions
2433 or the upcoming GNOME 3.8 release.
2435 Build-time configuration changes:
2437 • The --with-dbus-session-bus-default-address configure option is no longer
2438 supported. Use the new --with-dbus-session-bus-connect-address and
2439 --with-dbus-session-bus-listen-address options instead. On Windows, you
2440 usually want them to have the same argument; on Unix, the defaults are
2443 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2444 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2445 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2447 • cmake/cross-compile.sh has been removed. Instead, please use a
2448 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2449 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2450 as documented in "info automake Cross-Compilation", and set
2451 PKG_CONFIG_PATH appropriately.

2462 implements o.fd.DBus (fd.o #51865, Colin Walters)
2463 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
2464 · stop claiming that all basic types work just like INT32 (strings don't!)
2466 • The "source code" for the man pages is now Docbook XML, eliminating
2467 the outdated duplicate copies used when building with CMake.
2468 (fd.o #59805; Ralf Habacker, Simon McVittie)
2472 • In the activation helper, when compiled for tests, do not reset the system
2473 bus address, fixing the regression tests. (fd.o #52202, Simon)
2475 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
2476 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
2478 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

2497 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
2500 · The default session bus listening and connecting address is now
2501 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2502 and GDBus "out of the box". Use the configure options and cmake variables
2503 described above if you require a different autolaunch scope.
2504 (fd.o #38201, Simon McVittie)
2505 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
2507 • Create session.d, system.d directories under CMake (fd.o #41319,
2510 D-Bus 1.6.8 (2012-09-28)
2513 The "Fix one thing, break another" release.
2515 • Follow up to CVE-2012-3524: The additional hardening
2516 work to use __secure_getenv() as a followup to bug #52202
2517 broke certain configurations of gnome-keyring. Given
2518 the difficulty of making this work without extensive
2519 changes to gnome-keyring, use of __secure_getenv() is

2563 • Disconnect "developer mode" (assertions, verbose mode etc.) from
2564 Automake maintainer mode. D-Bus developers should now configure with
2565 --enable-developer. Automake maintainer mode is now on by default;
2566 distributions can disable it with --disable-maintainer-mode.
2567 (fd.o #34671, Simon McVittie)
2569 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
2570 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
2573 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
2575 D-Bus 1.6.0 (2012-06-05)
2578 The “soul of this machine has improved” release.
2580 This version starts a new stable branch of D-Bus: only bug fixes will
2581 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.

2631 an unused duplicate copy of the nonce-tcp transport in Windows builds
2632 (fd.o #45896, Simon McVittie)
2634 D-Bus 1.5.12 (2012-03-27)
2637 The “Big Book of Science” release.

2642 (fd.o #39549, Simon McVittie)
2644 • Turn DBusBasicValue into public API so bindings don't need to invent their
2645 own "union of everything" type (fd.o #11191, Simon McVittie)

2662 The "fire in Delerium" release.
2664 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2665 and SUSv2) is now required.
2667 • D-Bus Specification 0.19:
2668 · Formally define unique connection names and well-known bus names,
2669 and document best practices for interface, bus, member and error names,
2670 and object paths (fd.o #37095, Simon McVittie)
2671 · Document the search path for session and system services on Unix, and
2672 where they should be installed by build systems (fd.o #21620, fd.o #35306;
2674 · Document the systemd transport (fd.o #35232, Lennart Poettering)
2676 • Make dbus_threads_init() use the same built-in threading implementation
2677 as dbus_threads_init_default(); the user-specified primitives that it

2680 • Allow all configured auth mechanisms, not just one (fd.o #45106,
2683 • Improve cmake build system (Ralf Habacker):
2684 · simplify XML parser dependencies (fd.o #41027)

2686 · only create batch files on Windows
2687 · fix option and cache syntax
2688 · add help-options target
2689 · share dbus-arch-deps.h.in with autotools rather than having our
2690 own version (fd.o #41033)
2692 • Build tests successfully with older GLib, as found in e.g. Debian 6
2693 (fd.o #41219, Simon McVittie)
2695 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
2697 • Build documentation correctly if man2html doesn't support filenames on
2698 its command-line (fd.o #43875, Jack Nagel)
2700 • Improve test coverage. To get even more coverage, run the tests with
2701 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
2703 • Reduce the size of the shared library by moving functionality only used
2704 by dbus-daemon, tests etc. into their internal library and deleting
2705 unused code (fd.o #34976, #39759; Simon McVittie)
2707 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2708 setups where the default configuration must include <pidfile/> to avoid
2709 breaking traditional init, but the pid file is in fact unnecessary; use
2710 it under systemd to improve startup time a bit (fd.o #45520,
2713 • Optionally (if configured --with-valgrind) add instrumentation to debug
2714 libdbus and associated tools more meaningfully under Valgrind
2715 (fd.o #37286, Simon McVittie)

2719 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
2721 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
2722 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
2723 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
2726 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
2730 · Replace our broken reimplementation of recursive mutexes, which has
2731 been broken since 2006, with an ordinary pthreads recursive mutex
2732 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2733 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2734 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2735 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2736 · When running under systemd, use it instead of ConsoleKit to check
2737 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2738 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2739 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2740 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2741 (fd.o #41218, Simon McVittie)
2742 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2743 helper doesn't obey environment variables to avoid privilege escalation
2744 attacks, so make the system bus follow the same rules
2745 (fd.o #21620, Simon McVittie)
2748 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2749 Jesper Dam, Ralf Habacker)
2750 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
2753 D-Bus 1.5.8 (2011-09-21)

2758 In addition to dead code removal and refactoring, this release contains all
2759 of the bugfixes from 1.4.16.
2761 • Clean up dead code, and make more warnings fatal in development builds
2762 (fd.o #39231, fd.o #41012; Simon McVittie)
2764 • If full test coverage is requested via --enable-tests, strictly require
2765 Python, pygobject and dbus-python, which are required by some tests; if not,
2766 and Python is missing, skip those tests rather than failing
2767 (fd.o #37847, Simon McVittie)
2769 • When using cmake, provide the same version-info API in the installed headers
2770 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2772 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)

2781 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2782 (fd.o #39879, Chris Mayo)
2784 • Fix a small memory leak, and a failure to report errors, when updating
2785 a service file entry for activation (fd.o #39230, Simon McVittie)
2788 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2789 Brian Cameron, Simon McVittie)
2790 · On systems that use libcap-ng but not systemd, drop supplemental groups
2791 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2792 · Make the cmake build work again on GNU platforms (fd.o #29228,

2795 like Solaris (fd.o #40313, Dagobert Michelsen)
2796 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2797 (fd.o #40235, Simon McVittie)
2798 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2799 (fd.o #39987, Simon McVittie)
2800 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2801 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2804 · Fix compilation on MSVC, which doesn't understand "inline" with its
2805 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2806 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2807 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2809 D-Bus 1.5.6 (2011-07-29)
2812 The "weird, gravy-like aftertaste" release.
2814 In addition to new features and refactoring, this release contains all of the
2815 bugfixes from 1.4.14.
2817 Potentially incompatible (Bustle and similar debugging tools will need
2818 changes to work as intended):
2820 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2821 different recipient) by mistake: eavesdroppers must now opt-in to this
2822 behaviour by putting "eavesdrop='true'" in the match rule, which will
2823 not have any practical effect on buses where eavesdropping is not allowed
2824 (fd.o #37890, Cosimo Alfarano)
2828 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2829 Cosimo Alfarano, Simon McVittie)
2830 · add the "eavesdrop" keyword to match rules
2831 · define eavesdropping, unicast messages and broadcast messages
2832 · stop claiming that match rules are needed to match unicast messages to you
2833 · promote the type system to be a top-level section
2835 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2836 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2837 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2839 • Consistently use atomic operations on everything that is ever manipulated
2840 via atomic ops, as was done for changes to DBusConnection's refcount in
2841 1.4.12 (fd.o #38005, Simon McVittie)
2843 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2846 • Make "make check" in a clean tree work, by not running tests until
2847 test data has been set up (fd.o #34405, Simon McVittie)
2849 • The dbus-daemon no longer busy-loops if it has a very large number of file
2850 descriptors (fd.o #23194, Simon McVittie)
2852 • Refactor message flow through dispatching to avoid locking violations if
2853 the bus daemon's message limit is hit; remove the per-connection link cache,
2854 which was meant to improve performance, but now reduces it (fd.o #34393,
2857 • Some cmake fixes (Ralf Habacker)
2859 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2860 Simon McVittie, Lennart Poettering)
2862 • Stop storing two extra byte order indicators in each D-Bus message
2863 (fd.o #38287, Simon McVittie)
2865 • Add an optional Stats interface which can be used to get statistics from
2866 a running dbus-daemon if enabled at configure time with --enable-stats
2867 (fd.o #34040, Simon McVittie)
2869 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2871 • Documentation (fd.o #36156, Simon McVittie):
2872 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2873 · install more documentation automatically, including man2html output
2874 · put dbus.devhelp in the right place (it must go in ${htmldir})
2877 · look for system services in /lib/dbus-1/system-services in addition to all
2878 the other well-known locations; note that this should always be /lib,
2879 even on platforms where shared libraries on the root FS would go in /lib64,
2880 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2881 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2883 • Windows-specific (Ralf Habacker):
2884 · fix use of a mutex for autolaunch server detection
2885 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2887 D-Bus 1.5.4 (2011-06-10)
2890 Security (local denial of service):
2892 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2893 local DoS if foreign-endian messages are relayed through the dbus-daemon
2894 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2895 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2899 • The constant to use for an infinite timeout now has a name,
2900 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2901 which can be used for source compatibility with older versions of libdbus.
2903 • If GLib and DBus-GLib are already installed, more tests will be built,
2904 providing better coverage. The new tests can also be installed via
2905 ./configure --enable-installed-tests
2906 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2910 • Consistently use atomic operations for the DBusConnection's refcount,
2911 fixing potential threading problems (fd.o #38005, Simon McVittie)
2913 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2914 small (300KiB on x86-64) and it frequently doesn't work in unusual
2915 toolchains. To optimize for minimum installed size, you should benchmark
2916 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2917 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2919 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2920 (fd.o #35880, Timothy Redaelli)
2922 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2923 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2925 • Windows-specific changes:
2926 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2928 D-Bus 1.5.2 (2011-06-01)
2931 The "Boar Hunter" release.
2933 Notes for distributors:
2935 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2936 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2937 toolchain supports it reliably, via something like:
2939 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2941 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2945 • D-Bus Specification v0.17
2946 · Reserve the extra characters used in signatures by GVariant
2947 (fd.o #34529, Simon McVittie)
2948 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2949 • Don't force -fPIE: distributions and libtool know better than we do whether
2950 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2951 • Allow --disable-gc-sections, in case your toolchain offers the
2952 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2953 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2954 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2955 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2956 • Ensure that maintainers upload documentation with the right permissions
2957 (fd.o #36130, Simon McVittie)

2965 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
2966 (fd.o #35228, Lennart Poettering)
2967 • In the regression tests, don't report fds as "leaked" if they were open
2968 on startup (fd.o #35173, Simon McVittie)
2969 • Make dbus-monitor bail out if asked to monitor more than one bus,
2970 rather than silently using the last one (fd.o #26548, Will Thompson)
2971 • Clarify documentation (fd.o #35182, Simon McVittie)
2972 • Clean up minor dead code and some incorrect error handling

2983 flying shark" release.
2985 • D-Bus Specification v0.16
2986 · Add support for path_namespace and arg0namespace in match rules
2987 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
2988 · Make argNpath support object paths, not just object-path-like strings,
2989 and document it better (fd.o #31818, Will Thompson)
2990 • Let the bus daemon implement more than one interface (fd.o #33757,
2992 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2994 • Require user intervention to compile with missing 64-bit support
2995 (fd.o #35114, Simon McVittie)
2996 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
2997 • Raise UnknownObject instead of UnknownMethod for calls to methods on
2998 paths that are not part of the object tree, and UnknownInterface for calls
2999 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)

3004 The "It's like the beginning of a lobster" release.
3006 • Rename configure.in to configure.ac, and update it to modern conventions
3007 (fd.o #32245; Javier Jardón, Simon McVittie)
3008 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
3010 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
3011 --disable-x11-autolaunch configure option to prevent it altogether
3012 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
3013 • Install the documentation, and an index for Devhelp (fd.o #13495,
3014 Debian #454142; Simon McVittie, Matthias Clasen)
3015 • If checks are not disabled, check validity of string-like types and
3016 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
3017 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
3018 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
3019 • Break up a huge conditional in config-parser so gcov can produce coverage
3020 data (fd.o #10887, Simon McVittie)
3021 • List which parts of the Desktop Entry specification are applicable to
3022 .service files (fd.o #19159, Sven Herzberg)
3023 • Don't suppress service activation if two services have the same Exec=
3024 (fd.o #35750, Colin Walters)

3034 The "1, 2, miss a few, 99, 100" release.
3036 • Remove unfinished changes intended to support GTest-based tests,
3037 which were mistakenly included in 1.4.4
3039 D-Bus 1.4.4 (2010-02-17)
3042 • Switch back to using even micro versions for stable releases; 1.4.1
3043 should have been called 1.4.2, so skip that version number
3044 • Don't leave bad file descriptors being watched when spawning processes,
3045 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
3046 also LP#656134, LP#680444, LP#713157)
3047 • Check for MSG_NOSIGNAL correctly
3048 • Fix failure to detect abstract socket support (fd.o #29895)
3049 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
3050 (fd.o #32262, NB#180486)

3080 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
3081 crash the bus. The existing restriction to 64-levels of nesting previously
3082 only applied to the static type signature; now it also applies to dynamic
3083 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
3085 • OS X portability fixes, including launchd support.
