1 dbus 1.12.16 (UNRELEASED)
2 =========================
6 dbus 1.12.14 (2019-05-17)
7 =========================
9 The “reclaimed floorboards” release.
13 • Raise soft fd limit to match hard limit, even if unprivileged.
14 This makes session buses with many clients, or with clients that make
15 heavy use of fd-passing, less likely to suffer from fd exhaustion.
16 (dbus!103, Simon McVittie)
20 • If a privileged dbus-daemon has a hard fd limit greater than 64K, don't
21 reduce it to 64K, ensuring that we can put back the original fd limits
22 when carrying out traditional (non-systemd) activation. This fixes a
23 regression with systemd >= 240 in which system services inherited
24 dbus-daemon's hard and soft limit of 64K fds, instead of the intended
25 soft limit of 1K and hard limit of 512K or 1M.
26 (dbus!103, Debian#928877; Simon McVittie)
28 • Fix build failures caused by an AX_CODE_COVERAGE API change in newer
29 autoconf-archive versions (dbus#249, dbus!88; Simon McVittie)
31 • Fix build failures with newer autoconf-archive versions that include
32 AX_-prefixed shell variable names (dbus#249, dbus!86; Simon McVittie)
34 • Parse section/group names in .service files according to the syntax
35 from the Desktop Entry Specification, rejecting control characters
36 and non-ASCII in section/group names (dbus#208, David King)
38 • Fix various -Wlogical-op issues that cause build failure with newer
39 gcc versions (dbus#225, dbus!109; David King)
41 • Don't assume we can set permissions on a directory, for the benefit of
42 MSYS and Cygwin builds (dbus#216, dbus!110; Simon McVittie)
44 • Don't overwrite PKG_CONFIG_PATH and related environment variables when
45 the pkg-config-based version of DBus1Config is used in a CMake project
46 (dbus#267, dbus!96; Clemens Lang)
48 dbus 1.12.12 (2018-12-04)
49 =========================
51 The “draconic disciple” release.
53 dbus version control is now hosted on freedesktop.org's Gitlab
54 installation, and bug reports and feature requests have switched from
55 Bugzilla bugs (indicated by "fd.o #nnn") to Gitlab issues ("dbus#nnn")
56 and merge requests ("dbus!nnn").
60 • Reference the freedesktop.org Code of Conduct (Simon McVittie)
64 • Stop the dbus-daemon leaking memory (an error message) if delivering
65 the message that triggered auto-activation is forbidden. This is
66 technically a denial of service because the dbus-daemon will
67 run out of memory eventually, but it's a very slow and noisy one,
68 because all the rejected messages are also very likely to have
69 been logged to the system log, and its scope is typically limited by
70 the finite number of activatable services available.
71 (dbus#234, Simon McVittie)
73 • Remove __attribute__((__malloc__)) attribute on dbus_realloc(),
74 which does not meet the criteria for that attribute in gcc 4.7+,
75 potentially leading to miscompilation (fd.o #107741, Simon McVittie)
77 • Fix some small O(1) memory leaks (fd.o #107320, Simon McVittie)
79 • Fix printf formats for pointer-sized integers on 64-bit Windows
80 (fd.o #105662, Ralf Habacker)
82 • Always use select()-based poll() emulation on Darwin-based OSs
83 (macOS, etc.) and on Interix, similar to what libcurl does
84 (dbus#232, dbus!19; Simon McVittie)
86 • Extend a test timeout to avoid spurious failures in CI
87 (dbus!26, Simon McVittie)
91 • Add Travis-CI builds for 64-bit Windows using mingw-w64
92 (fd.o #105662, Ralf Habacker)
94 • Add Gitlab-CI integration (fd.o #108177, Simon McVittie)
96 dbus 1.12.10 (2018-08-02)
97 =========================
99 The “beam deflection” release.
103 • Prevent reading up to 3 bytes beyond the end of a truncated message.
104 This could in principle be an information leak or denial of service
105 on the system bus, but is not believed to be exploitable to crash
106 the system bus or leak interesting information in practice.
107 (fd.o #107332, Simon McVittie)
109 • Fix build with gcc 8 -Werror=cast-function-type
110 (fd.o #107349, Simon McVittie)
112 • Fix warning from gcc 8 about suspicious use of strncpy() when
113 populating struct sockaddr_un (fd.o #107350, Simon McVittie)
115 • Fix a minor memory leak when a DBusServer listens on a new address
116 (fd.o #107194, Simon McVittie)
118 • Fix an invalid NULL argument to rmdir() if a nonce-tcp DBusServer
119 runs out of memory (fd.o #107194, Simon McVittie)
121 • Don't use misleading errno-derived error names if getaddrinfo() or
122 getnameinfo() fails with a code other than EAI_SYSTEM
123 (fd.o #106395, Simon McVittie)
125 • Skip tests that require working TCP if we are in a container environment
126 where 127.0.0.1 cannot be resolved (fd.o #106812, Simon McVittie)
128 dbus 1.12.8 (2018-04-30)
129 ========================
131 The “golden super-velociraptor” release.
135 • The Devhelp documentation index is now in version 2 format
136 (fd.o #106186, Simon McVittie)
138 • Give the dbus-daemon man page some scarier warnings about
139 <allow_anonymous/> and non-local TCP, which are insecure and should
140 not be used, particularly for the standard system and session buses
141 (fd.o #106004, Simon McVittie)
145 • Fix installation of Ducktype documentation with newer yelp-build
146 versions (fd.o #106171, Simon McVittie)
148 dbus 1.12.6 (2018-03-01)
149 ========================
151 The “just the one swan, actually” release.
155 • Increase system dbus-daemon's RLIMIT_NOFILE rlimit before it drops
156 privileges, because it won't have permission afterwards. This fixes a
157 regression in dbus 1.10.18 and 1.11.0 which made the standard system bus
158 more susceptible to deliberate or accidental denial of service.
159 (fd.o #105165, David King)
161 dbus 1.12.4 (2018-02-08)
162 ========================
164 The “Stria Campania 115” release.
168 • When iterating the DBusConnection while blocking on a pending call,
169 don't wait for I/O if that pending call already has a result; and make
170 sure that whether it has a result is propagated in a thread-safe way.
171 This prevents certain multi-threaded calling patterns from blocking
172 until their timeout even when they should have succeeded sooner.
173 (fd.o #102839; Manish Narang, Michael Searle)
175 • Report the correct error if OOM is reached while trying to listen
176 on a TCP socket (fd.o #89104, Simon McVittie)
178 • Fix assertion failures in recovery from OOM while setting up a
179 DBusServer (fd.o #89104, Simon McVittie)
181 • Add a missing space to a warning message (fd.o #103729, Thomas Zajic)
183 • Expand ${bindir} correctly when pkg-config is asked for dbus_daemondir
184 (fd.o #104265, Benedikt Heine)
186 • On Linux systems with systemd < 237, if ${localstatedir}/dbus doesn't
187 exist, create it before trying to create ${localstatedir}/dbus/machine-id
188 (fd.o #104577, Chris Lesiak)
190 • Fix escaping in dbus-api-design document (fd.o #104925, Philip Withnall)
192 dbus 1.12.2 (2017-11-13)
193 ========================
195 The “spider pumpkin” release.
199 • Log a warning if a new connection cannot be accepted due to an
200 out-of-memory condition or failure to identify its AppArmor or
201 SELinux context (fd.o #103592, Simon McVittie)
205 • Make use of $(MKDIR_P) compatible with install-sh, fixing build when a
206 GNU-compatible `mkdir -p` is not available (fd.o #103521, ilovezfs)
208 • When building for Windows with Autotools, avoid `echo -e`, fixing
209 cross-compilation on non-GNU platforms like macOS
210 (fd.o #103493, Tony Theodore)
212 • Fix crashes in the server side of the nonce-tcp: transport under
213 various error conditions. This transport should normally only be used
214 on Windows, where AF_UNIX sockets are unavailable; the unix: transport
215 is the only one recommended for production use on Unix platforms.
216 (fd.o #103597, Simon McVittie)
220 • Improve test coverage on Travis-CI (Simon McVittie)
222 dbus 1.12.0 (2017-10-30)
223 ========================
225 The “gingerbread skull” release.
227 1.12.x is a new stable branch, recommended for use in OS
230 Summary of major changes between 1.10.x and 1.12.0
231 --------------------------------------------------
235 • Expat >= 2.1.0 is required.
236 • GLib >= 2.40 is required if full test coverage is enabled.
237 • [Linux] libselinux >= 2.0.86 is required if SELinux support is
239 • [Unix] dbus now requires an <inttypes.h> that defines C99 constants
240 such as PRId64 and PRIu64, except when building for Windows.
241 • [Autotools] Building from git (but not from tarballs) with Autotools
242 now requires macros from the GNU Autoconf Archive.
243 • [CMake] Builds done using CMake now require CMake 3.0.2.
245 Build-time configuration changes:
247 • Expat is now found using pkg-config. See the release notes for
249 • The --disable-compiler-optimisations and --enable-compiler-coverage
250 options no longer exist. See the release notes for 1.11.4 and 1.11.8.
251 • [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
252 options no longer exist. See the release notes for 1.11.20.
253 • [Unix] Flag files in /var/run/console/${username} are no longer
254 checked for at_console by default. See the release notes for 1.11.18.
255 • [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
256 and packagers will now need to add these downstream (most already do).
257 See the release notes for 1.11.18.
258 • [Unix] The process ID file no longer has a different default location
259 on Red Hat derivatives. See the release notes for 1.11.18.
260 • [Unix] ${runstatedir} is now independent of ${localstatedir} with
261 recent Autotools versions. See the release notes for 1.11.16.
262 • [Windows] The WINDRES variable is no longer used. See the release
267 • Eavesdropping is officially deprecated in favour of BecomeMonitor.
268 See the release notes for spec version 0.31 (in dbus 1.11.14).
269 • [Unix] Flag files in /var/run/console/${username} are deprecated.
270 See the release notes for 1.11.18.
274 • <allow> and <deny> rules in dbus-daemon configuration can now
275 include send_broadcast="true", send_broadcast="false",
276 max_unix_fds="N", min_unix_fds="N" (for some integer N).
277 See the release notes for 1.11.18.
278 • dbus_try_get_local_machine_id() is like
279 dbus_get_local_machine_id(), but returns a DBusError.
280 • New APIs around DBusMessageIter to simplify cleanup.
281 See the release notes for 1.11.16.
282 • The message bus daemon now implements the standard Introspectable,
283 Peer and Properties interfaces. See the release notes for
284 dbus 1.11.14 and spec version 0.31.
285 • DTDs for introspection XML and bus configuration are installed.
286 • dbus can be compiled to be relocatable, making it more suitable for
287 binary bundling with other software. On Windows, this is on by
289 • [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
290 never uses Linux abstract sockets, which is advantageous for
291 containers. On non-Linux it is equivalent to unix:tmpdir=….
292 See the release notes for dbus 1.11.14 and spec version 0.31.
293 • [Unix] New option "dbus-launch --exit-with-x11".
294 • [Unix] Session managers can create transient .service files in
295 $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
296 • [Unix] A sysusers.d snippet can create the messagebus user on-demand.
298 Miscellaneous behaviour changes:
300 • [Unix] The session bus now logs to syslog if it was started by
302 • [Unix] Internal warnings are logged to syslog if configured.
303 • [Unix] Exceeding an anti-DoS limit is logged to syslog if configured,
306 Changes since 1.11.22 release candidate
307 ---------------------------------------
309 Standard stable-branch changes:
311 • Disable warnings about use of deprecated functions (Simon McVittie)
315 • Don't distribute files generated by ./configure in the source tarball
316 (fd.o #103420, Simon McVittie)
320 • Remove some unused files from the git repository
321 (fd.o #103420, Simon McVittie)
323 D-Bus 1.11.22 (2017-10-23)
324 ==========================
326 The “fire surface” release.
328 This is the first release-candidate for the 1.12.0 stable release.
330 Build-time configuration changes:
332 • When building for Windows with Autotools, setting the WINDRES variable
333 no longer works to select a non-standard resource compiler. Use
334 libtool's standard RC variable instead, for example
335 "./configure RC=i686-w64-mingw32-windres"
339 • Builds done using CMake now require CMake 3.0.2.
343 • When building for Windows, improve quality of metadata in
344 libdbus-1-3.dll (fd.o #103015, Ralf Habacker)
348 • Fix a typo "uint 16" in dbus-send(1) man page
349 (fd.o #103075, David King)
351 • When building for Windows, libdbus-1-3.dll always includes version
352 information. Previously, this was missing if using CMake and any
353 non-MSVC compiler. (fd.o #103015, Ralf Habacker)
355 • Fix the build with MSVC, which regressed with the #102558 fix in
356 1.11.20. (fd.o #102558, Ralf Habacker)
360 • Simplify Windows resource embedding
361 (fd.o #103015, Simon McVittie)
363 D-Bus 1.11.20 (2017-10-03)
366 The “wraith stun” release.
368 Build-time configuration changes:
370 • The --enable-abstract-sockets and --disable-abstract-sockets options
371 no longer exist. Support for Linux's abstract AF_UNIX sockets is now
372 unconditionally enabled on Linux and disabled everywhere else.
373 (fd.o #34905, Simon McVittie)
377 • Make slower tests less likely to time out, and improve diagnostics if
378 tests do time out (fd.o #103009, Simon McVittie)
380 • On Windows, don't compile an unused stub implementation of
381 _dbus_set_signal_handler() (fd.o #103010, Simon McVittie)
385 • Be more careful to save and restore errno in POSIX async signal
386 handlers (fd.o #103010, Simon McVittie)
388 • On Windows, embed a manifest in dbus-update-activation-environment.exe
389 so that the heuristics used for UAC do not assume it needs elevated
390 privileges due to its name containing "update"
391 (fd.o #102558, Ralf Habacker)
393 • On Windows with Automake, embed version information in libdbus-1,
394 as was meant to happen in all versions since 2009
395 (fd.o #103015, Simon McVittie)
397 D-Bus 1.11.18 (2017-09-25)
400 The “vampire conquistador” release.
402 Build-time configuration changes:
404 • By default, dbus-daemon on Unix no longer checks for flag files
405 /var/run/console/${username} created by the obsolete pam_console and
406 pam_foreground PAM modules when deciding whether ${username} is
407 currently at the console. The old default behaviour can be restored
408 by specifying --with-console-auth-dir=/var/run/console in the
409 recommended Autotools build system, or
410 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
411 now deprecated, and will be removed in dbus 1.13 unless feedback via
412 fd.o #101629 indicates that this would be problematic.
413 (fd.o #101629, Simon McVittie)
415 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
416 script for Cygwin, are no longer provided in the upstream dbus
417 source. We recommend that distributors who support non-systemd service
418 management should maintain their own init scripts or other service
419 manager integration as part of their downstream packaging, similar to
420 the way Debian distributes a Debian-specific LSB init script for dbus.
422 The systemd unit continues to be maintained as part of the upstream
423 dbus source, because it receives regular testing and maintenance.
425 (fd.o #101706, Simon McVittie)
427 • The process ID file created by the system bus is no longer influenced
428 by the --with-init-scripts=redhat configure option or the presence of
429 /etc/redhat-release at build time. If your OS's init script or other
430 service management relies on the Red Hat-style pid file, it can be
431 restored by specifying --with-system-pid-file=/run/messagebus.pid at
432 configure time or using the <pidfile> directive in bus configuration.
434 Note that the upstream-supplied systemd unit runs dbus-daemon with
435 the --nopidfile option, so it does not normally write a pid file,
436 regardless of whether the OS is Red-Hat-derived or not.
438 (fd.o #101706, Simon McVittie)
442 • <allow> and <deny> rules in dbus-daemon configuration can now
443 include send_broadcast="true" or send_broadcast="false", which make
444 the rule only match broadcast signals, or only match messages that
445 are not broadcast signals, respectively.
446 (fd.o #29853, Simon McVittie)
448 • <allow> and <deny> rules can now be configured to apply only to
449 messages with or without Unix file descriptors attached. This would
450 typically be used in rules like these:
451 <allow send_destination="..." max_unix_fds="0"/>
452 <deny send_destination="..." min_unix_fds="1"/>
453 <deny receive_sender="..." min_unix_fds="1"/>
454 but can also be used to set a nonzero upper limit on the number of
456 <allow send_destination="..." max_unix_fds="4"/>
457 (fd.o #101848, Simon McVittie)
459 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
460 now respects the HOME environment variable on the client side, and
461 on the server side when the uid attempting to connect is the same
462 as the uid of the server. This allows the automated tests to pass in
463 environments where the user's "official" home directory in /etc/passwd
464 is nonexistent, such as Debian autobuilders.
465 (fd.o #101960, Simon McVittie)
469 • When parsing dbus-daemon configuration, tell Expat not to use
470 cryptographic-quality entropy as a salt for its hash tables: we trust
471 the configuration files, so we are not concerned about algorithmic
472 complexity attacks via hash table collisions. This prevents
473 dbus-daemon --system from holding up the boot process (and causing
474 early-boot system services like systemd, logind, networkd to time
475 out) on entropy-starved embedded systems.
476 (fd.o #101858, Simon McVittie)
478 • Avoid a -Werror=declaration-after-statement build failure on Solaris
479 (fd.o #102145, Alan Coopersmith)
481 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
482 to LOG_INFO, matching how we use this log level in practice
483 (fd.o #102686, Simon McVittie)
485 D-Bus 1.11.16 (2017-07-27)
488 The “south facing garden” release.
490 Build-time configuration changes:
492 • The Autotools build system now supports varying ${runstatedir}
493 independently of ${localstatedir}, if using an Autoconf version
494 that has that feature; version 2.70 will eventually have this, but
495 many Linux distributions add it to version 2.69 as a patch.
496 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
497 and runstatedir=/run. (fd.o #101569, Simon McVittie)
501 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
502 and dbus_message_iter_abandon_container_if_open() simplify the
503 single-exit-point ("goto out") style of resource cleanup. The API
504 documentation around DBusMessageIter and containers has also been
505 clarified. (fd.o #101568, Simon McVittie)
509 • Fix the implementation of re-enabling a timeout (again) so that its
510 countdown is always restarted as intended. (fd.o #95619,
513 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
514 available to all users on the system bus (fd.o #101700, Simon McVittie)
516 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
517 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
519 • dbus_message_iter_open_container() no longer leaks memory if it runs out
520 of memory. (fd.o #101568, Simon McVittie)
522 • dbus_message_append_args_valist() no longer leaks memory if given an
523 unsupported type. This situation is still considered to be a programming
524 error which needs to be corrected by the user of libdbus.
525 (fd.o #101568, Simon McVittie)
527 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
528 will no longer report that their arguments were invalid if they run out
529 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
531 • Ensure that tests fail if they would otherwise have tried to connect to
532 the real session bus (fd.o #101698, Simon McVittie)
534 • Make build-time tests cope with finding Python 3, but not Python 2
535 (fd.o #101716, Simon McVittie)
537 Internal changes relevant to dbus developers:
539 • DBusVariant is a new mechanism to copy single values from a message into
540 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
542 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
543 Logging an ERROR message does not make the process exit; the caller
544 is responsible for calling abort() or exit(), whichever is more appropriate.
545 (fd.o #101568, Simon McVittie)
547 • Better test coverage (fd.o #101568, Simon McVittie)
549 D-Bus 1.11.14 (2017-06-29)
552 The “irrational fear of bees” release.
556 • Expat >= 2.1.0 is always required
557 • libselinux >= 2.0.86 is required if SELinux support is enabled
558 • GLib >= 2.40 is required if full test coverage is enabled
560 Build-time configuration changes:
562 • We now use pkg-config to find libexpat in Autotools builds. This requires
563 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
564 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
565 itself cause compilation failures.
567 As with all pkg-config-based configure checks, you can use
568 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
569 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
570 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
573 (fd.o #69801, Simon McVittie)
575 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
576 is required due to the removal of explicit refcounting for SIDs.
577 (fd.o #100912, Laurent Bigonville)
581 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
582 as a side-effect of a sufficiently privileged process merely reading the
583 machine ID. It is no longer copied as a side-effect of reading.
584 Running dbus-uuidgen --ensure, which should be done after installing dbus,
585 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
586 former exists and the latter does not.
587 (fd.o #101257, Simon McVittie)
589 • The undocumented Verbose interface, and the GetAllMatchRules method on
590 the undocumented Stats interface, must now be used via the object path
591 /org/freedesktop/DBus. Previously, they existed on all object paths.
592 (fd.o #101257, Simon McVittie)
594 • AddMatch() with a match rule containing eavesdrop='true' will now fail
595 unless called by either the same user as the dbus-daemon, or Unix uid 0
596 (root), matching the restrictions applied to the newer BecomeMonitor()
597 method. On the session bus this has no practical effect. On the system
598 bus this will prevent certain configurations that already did not
599 work well in practice. (fd.o #101567, Simon McVittie)
603 • D-Bus Specification version 0.31
604 · Don't require implementation-specific search paths to be lowest
606 · Correct regex syntax for optionally-escaped bytes in addresses so it
607 includes hyphen-minus, forward slash and underscore as intended
608 · Describe all message bus methods in the same section
609 · Clarify the correct object path for method calls to the message bus
610 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
611 · Document that the message bus implements Introspectable, Peer and
613 · Add new Features and Interfaces properties for message bus
615 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
617 · Don't require eavesdrop='true' to be accepted from connections not
618 sufficiently privileged to use it successfully
619 · Formally deprecate eavesdropping in favour of BecomeMonitor
620 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
621 Simon McVittie, Tom Gundersen)
623 • Implement the Properties and Peer interfaces in dbus-daemon
624 (fd.o #101257, Simon McVittie)
626 • New function dbus_try_get_local_machine_id() is like
627 dbus_get_local_machine_id(), but returning a DBusError. Other code
628 that needs the machine ID will now report a recoverable error (instead
629 of logging to stderr and aborting) if no machine ID is available.
630 Generating a machine ID is still considered to be a required part of
631 installing dbus correctly. (fd.o #13194, Simon McVittie)
633 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
634 (fd.o #101315, Laurent Bigonville)
636 • Avoid deprecated API calls when using SELinux
637 (fd.o #100912, Laurent Bigonville)
639 • Switch a test from the deprecated g_test_trap_fork() to
640 g_test_trap_subprocess(), for Windows support and better robustness
641 on Unix (fd.o #101362, Simon McVittie)
643 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
644 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
645 This prevents the two files from going out of sync on stateless or live
646 images without needing to run dbus-uuidgen, and supports older D-Bus
647 implementations that do not necessarily read /etc/machine-id themselves.
648 (fd.o #101570, Simon McVittie)
650 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
651 abstract sockets. This is preferable when used with Linux containers.
652 (fd.o #101567, Simon McVittie)
656 • Fix a reference leak when blocking on a pending call on a connection
657 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
659 • Don't put timestamps in the Doxygen-generated documentation,
660 or hard-code the build directory into builds with embedded tests,
661 for reproducible builds (fd.o #100692, Simon McVittie)
663 • Fix some integration test issues (fd.o #100686, Simon McVittie)
665 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
667 • If we somehow get an autolaunch address with multiple semicolon-separated
668 components, and they don't work, don't invalidly "pile up" errors
669 (fd.o #101257, Simon McVittie)
673 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
674 (fd.o #100715, Simon McVittie)
676 D-Bus 1.11.12 (2017-04-07)
679 The “it's something humans do” release.
683 • The session dbus-daemon now supports transient .service files
684 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
685 service directories, this directory is not monitored with inotify
686 or similar, and the service files must be named exactly
687 ${bus_name}.service. (fd.o #99825, Simon McVittie)
689 • dbus can be configured with --enable-relocation when building with
690 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
691 to make the pkg-config metadata relocatable. This is useful for
692 non-standard prefixes, and in particular for Windows installations.
693 However, it is not recommended for system-wide installations into
694 /usr, because it interferes with pkg-config's ability to filter out
695 compiler default linker directories.
697 With Autotools, the default is --enable-relocation when building
698 for Windows or --disable-relocation otherwise. With CMake, the default
699 is -DDBUS_RELOCATABLE=ON.
701 (fd.o #99721; Ralf Habacker, Simon McVittie)
703 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
704 own FindDBus.cmake macros, whether dbus was compiled with Autotools
705 or with CMake. See the end of README.cmake for more information.
706 (fd.o #99721; Ralf Habacker, Simon McVittie)
710 • Always read service file directories in the intended order
711 (fd.o #99825, Simon McVittie)
713 • When tests are skipped, don't try to kill nonexistent process 0
714 (fd.o #99825, Simon McVittie)
716 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
718 • Fix a harmless read overflow and some memory leaks in a unit test
719 (fd.o #100568, Philip Withnall)
721 • Fix some typos in test code
722 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
724 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
725 in documentation (fd.o #99901, Philip Withnall)
727 • Fix and enable compiler warnings related to -Wswitch
728 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
730 • Fix writing off the end of a fd_set when testing with valgrind
731 (fd.o #99839, Philip Withnall)
733 D-Bus 1.11.10 (2017-02-16)
736 The “purple hair gives you telekinesis?” release.
740 • AppArmor support requires at least libapparmor 2.8.95, reduced
741 from 2.10 in previous versions. One test requires 2.10 and is
742 skipped if building with an older version.
746 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
747 stable and Debian testing in addition to the older Ubuntu that is
748 the default (fd.o #98889, Simon McVittie)
750 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
752 • Silence many -Wswitch-enum and -Wswitch-default warnings
753 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
755 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
756 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
758 • Install pkg-config metadata on Unix even if building with CMake
759 (fd.o #99752, Ralf Habacker)
761 • Exclude auth mechanisms from REJECTED message if they are supported
762 in the code but but configured to be disallowed (fd.o #99621,
767 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
768 allow an attacker to overwrite a file named "nonce", in a directory
769 that the user running dbus-daemon can write, with a random value
770 known only to the user running dbus-daemon. This is unlikely to be
771 exploitable in practice, particularly since the nonce-tcp transport
772 is really only useful on Windows.
774 On Unix systems we strongly recommend using only the unix: and systemd:
775 transports, together with EXTERNAL authentication. These are the only
776 transports and authentication mechanisms enabled by default.
778 (fd.o #99828, Simon McVittie)
780 • Avoid symlink attacks in the "embedded tests", which are not enabled
781 by default and should never be enabled in production builds of dbus.
782 (fd.o #99828, Simon McVittie)
784 • Fix the implementation of re-enabling a timeout so that its
785 countdown is restarted as intended, instead of continually
786 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
788 • When receiving a message with file descriptors, do not start reading
789 the beginning of the next message, so that only one such message
790 is processed at a time. In conjunction with the fix for #95619
791 this means that processes sending many file descriptors, such as
792 systemd-logind on a system that receives very rapid ssh connections,
793 are not treated as abusive and kicked off the bus. Revert the previous
794 workaround that special-cased uid 0.
795 (fd.o #95263, LP#1591411; Simon McVittie)
797 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
798 for Windows with CMake (fd.o #99586, Ralf Habacker)
800 • Do not set Unix-specific variables when targeting Windows
801 (fd.o #99586, Ralf Habacker)
803 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
804 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
806 • Use relative install locations in CMake on Unix to respect DESTDIR,
807 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
809 • Install dbus-arch-deps.h correctly when using CMake
810 (fd.o #99586, #99721; Ralf Habacker)
812 • Improve argument validation for `dbus-test-tool spam`
813 (ffd.o #99693, Coverity #54759; Philip Withnall)
815 • Don't shift by a negative integer if a hash table becomes monstrously
816 large (fd.o #99641, Coverity #54682; Philip Withnall)
818 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
819 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
821 • Remove an unnecessary NULL check
822 (fd.o #99642, Coverity #141062; Philip Withnall)
824 • Improve error handling in unit tests and dbus-send
825 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
826 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,
827 #54710, #54711, #54714, #54715, #54718, #54721, #54724, #54726,
828 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
830 • Do not print verbose messages' timestamps to stderr if the actual message
831 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
833 D-Bus 1.11.8 (2016-11-28)
836 The “panics in the face of breakfast foods” release.
838 Build-time configuration:
840 • The new --enable-debug configure option provides an easy way to
841 enable debug symbols, disable optimization and/or enable profiling.
843 • The --enable-compile-warnings configure option can be used to control
846 • The --disable-compiler-optimisations configure option is no longer
847 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
851 • D-Bus Specification version 0.30
852 · Define the jargon term "activation" more clearly
853 · Define the jargon term "auto-starting", which is one form of activation
854 · Document the optional SystemdService key in service files
855 · Use versioned interface and bus names in most examples
856 · Clarify intended behaviour of Properties.GetAll
857 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
859 • Fix and enable a lot of compiler warnings to improve future code
860 quality. This might incidentally also fix some environment variable
862 · In particular, printf-style functions in the libdbus API are now annotated
863 with __attribute__((__format__(__printf__, *, *))) when compiling with
864 gcc or clang. This might make printf bugs in other software visible
866 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
867 Thomas Zimmermann, Simon McVittie)
869 • When running with AppArmor mediation (for example using Ubuntu's patched
870 Linux kernel), clients can no longer auto-start services unless they would
871 have been able to send the auto-starting message to the service after it
872 starts. StartServiceByName() is unaffected, and continues to be allowed by
873 default in AppArmor's <abstractions/dbus-strict> and
874 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
878 • Work around an undesired effect of the fix for CVE-2014-3637
879 (fd.o #80559), in which processes that frequently send fds, such as
880 logind during a flood of new PAM sessions, can get disconnected for
881 continuously having at least one fd "in flight" for too long;
882 dbus-daemon interprets that as a potential denial of service attack.
883 The workaround is to disable that check for uid 0 process such as
884 logind, with a message in the system log. The bug remains open while
885 we look for a more general solution.
886 (fd.o #95263, LP#1591411; Simon McVittie)
888 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
889 was disabled at compile time. That test is not expected to work
890 in that configuration. (fd.o #98665, Simon McVittie)
892 D-Bus 1.11.6 (2016-10-10)
895 The “darkly whimsical” release.
899 • Do not treat ActivationFailure message received from root-owned systemd
900 name as a format string. In principle this is a security vulnerability,
901 but we do not believe it is exploitable in practice, because only
902 privileged processes can own the org.freedesktop.systemd1 bus name, and
903 systemd does not appear to send activation failures that contain "%".
905 Please note that this probably *was* exploitable in dbus versions
906 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
907 the time was only thought to be a denial of service vulnerability
908 (CVE-2015-0245). If you are still running one of those versions,
909 patch or upgrade immediately.
911 (fd.o #98157, Simon McVittie)
915 • D-Bus Specification version 0.29
916 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
917 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
919 • Log to syslog when we exceed various anti-DoS limits, and add test
920 coverage for them (fd.o #86442, Simon McVittie)
922 • Improve syslog handling so that _dbus_warn() and similar warnings
923 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
924 and log to syslog (instead of /dev/null) when dbus-daemon is started by
925 dbus-launch. (fd.o #97009, Simon McVittie)
927 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
928 (fd.o #89011, Philip Withnall)
930 • When logging messages about service activation, mention which peer
931 requested the activation (fd.o #68212, Philip Withnall)
933 • On Linux, mention the LSM label (if available) whenever we print
934 debug information about a peer (fd.o #68212, Philip Withnall)
938 • Harden dbus-daemon against malicious or incorrect ActivationFailure
939 messages by rejecting them if they do not come from a privileged
940 process, or if systemd activation is not enabled
941 (fd.o #98157, Simon McVittie)
943 • Avoid undefined behaviour when setting reply serial number without going
944 via union DBusBasicValue (fd.o #98035, Marc Mutz)
946 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
947 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
949 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
951 D-Bus 1.11.4 (2016-08-15)
954 The “copper pickaxe” release.
958 • Building from git (but not from tarballs) now requires
959 macros from the GNU Autoconf Archive, for example the autoconf-archive
960 package in Debian or Fedora derivatives.
962 Build-time configuration:
964 • The option to enable coverage instrumentation has changed from
965 --enable-compiler-coverage to --enable-code-coverage.
969 • D-Bus Specification version 0.28
970 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
972 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
973 minimizing failed connections under heavy load
974 (fd.o #95264, Lennart Poettering)
976 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
978 • Use the same regression tests for subprocess starting on Unix and Windows
979 (fd.o #95191, Ralf Habacker)
981 • Print timestamps and thread IDs in verbose messages
982 (fd.o #95191, Ralf Habacker)
984 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
985 pointing to /dev/null (fd.o #97008, Simon McVittie)
987 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
988 (fd.o #88922, Thomas Zimmermann)
992 • On Windows, fix a memory leak in replacing the installation prefix
993 (fd.o #95191, Ralf Habacker)
995 • On Linux, when dbus-daemon is run with reduced susceptibility to the
996 OOM killer (typically via systemd), do not let child processes inherit
997 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
999 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
1000 even if a parent process incorrectly starts them with stdin, stdout
1001 and/or stderr closed (fd.o #97008, Simon McVittie)
1003 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
1004 contains a semicolon (fd.o #94746, Thiago Macieira)
1006 • Fix memory leaks and thread safety in subprocess starting on Windows
1007 (fd.o #95191, Ralf Habacker)
1009 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
1010 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
1012 • In tests that exercise correct handling of crashing D-Bus services,
1013 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
1015 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
1017 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
1018 in some test cases (fd.o #93909, Nick Lewycky)
1020 • Add assertions to reassure a static analysis tool
1021 (fd.o #93210, Deepika Aggarwal)
1023 • Be explicit about enum comparison when loading XML
1024 (fd.o #93205, Deepika Aggarwal)
1026 • update-activation-environment: produce better diagnostics on error
1027 (fd.o #96653, Simon McVittie)
1029 • Avoid various compiler warnings with gcc 6
1030 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
1032 • On Unix when configured to use the system log, report as "dbus-daemon",
1033 not as "dbus" (fd.o #97009, Simon McVittie)
1035 • During unit tests, reduce the amount we write to the system log
1036 (fd.o #97009, Simon McVittie)
1038 D-Bus 1.11.2 (2016-03-07)
1041 The “pneumatic drill vs. Iron Maiden” release.
1045 • Enable "large file support" on systems where it exists: dbus-daemon
1046 is not expected to open large files, but it might need to stat files
1047 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
1049 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
1050 which might result in a pedantic C compiler not copying the entire contents
1051 of a DBusMessageIter; statically assert that this is not an ABI change
1052 in practice (fd.o #94136, Simon McVittie)
1054 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
1055 (fd.o #94244, Dmitri Iouchtchenko)
1057 • Correctly report test failures in C tests from run-test.sh
1058 (fd.o #93379; amit tewari, Simon McVittie)
1060 • When tests are enabled, run all the marshal-validate tests, not just
1061 the even-numbered ones (fd.o #93908, Nick Lewycky)
1063 • Correct the expected error from one marshal-validate test, which was
1064 previously not run due to the above bug (fd.o #93908, Simon McVittie)
1066 • Fix compilation under CMake when embedded tests are disabled
1067 (fd.o #94094, eric.hyer)
1071 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
1072 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
1074 • When building with CMake, use the same gcc/clang warnings as under Autotools,
1075 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
1077 • test/name-test: make C tests produce TAP output and run them directly, not
1078 via run-test.sh (fd.o #92899, Simon McVittie)
1080 • Under CMake when cross-compiling for Windows on Unix, run the tests
1081 under Wine even if binfmt_misc support is not available
1082 (fd.o #88966, Ralf Habacker)
1084 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
1085 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
1087 • Factor out some functions that will be needed in future for a Windows
1088 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
1090 D-Bus 1.11.0 (2015-12-02)
1093 The “peppermint deer” release.
1097 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
1098 C99 constants such as PRId64 and PRIu64.
1102 • D-Bus Specification version 0.27
1103 · Specify that services should not reply if NO_REPLY_EXPECTED was used
1104 (fd.o #75749, Lars Uebernickel)
1106 • Add a script to do continuous-integration builds, and metadata to run it
1107 on travis-ci.org. To use this, clone the dbus git repository on GitHub
1108 and set it up with travis-ci.org; the only special setting needed is
1109 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
1111 • If dbus-daemon is run with --systemd-activation, do not require
1112 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
1116 • Re-order dbus-daemon startup so that on SELinux systems, the thread
1117 that reads AVC notifications retains the ability to write to the
1118 audit log (fd.o #92832, Laurent Bigonville)
1120 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
1122 • When using the Monitoring interface, match messages' destinations
1123 (fd.o #92074, Simon McVittie)
1125 • On Linux with systemd, stop installing a reference to the obsolete
1126 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
1129 • On Windows, when including configuration files with <include> or
1130 <includedir>, apply the same relocation as for the Exec paths
1131 in .service files (fd.o #92028, Simon McVittie)
1133 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
1135 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
1137 D-Bus 1.10.6 (2015-12-01)
1140 The “marzipan beetles” release.
1144 • On Unix when running tests as root, don't assert that root and
1145 the dbus-daemon user can still call UpdateActivationEnvironment;
1146 assert that those privileged users can call BecomeMonitor instead
1147 (fd.o #93036, Simon McVittie)
1149 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
1152 • On Windows Autotools builds, don't run tests that rely on
1153 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
1155 D-Bus 1.10.4 (2015-11-17)
1158 The “Frostburn Canyon” release.
1162 • GetConnectionCredentials, GetConnectionUnixUser and
1163 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
1164 will now return details of the dbus-daemon itself. This is required
1165 to be able to call SetEnvironment on systemd.
1166 (fd.o #92857, Jan Alexander Steffens)
1170 • Make UpdateActivationEnvironment always fail with AccessDenied on the
1171 system bus. Previously, it was possible to configure it so root could
1172 call it, but the environment variables were not actually used,
1173 because the launch helper would discard them.
1174 (fd.o #92857, Jan Alexander Steffens)
1176 • On Unix with --systemd-activation on a user bus, make
1177 UpdateActivationEnvironment pass on its arguments to systemd's
1178 SetEnvironment method, solving inconsistency between the environments
1179 used for traditional activation and systemd user-service activation.
1180 (fd.o #92857, Jan Alexander Steffens)
1182 • On Windows, don't crash if <syslog/> or --syslog is used
1183 (fd.o #92538, Ralf Habacker)
1185 • On Windows, fix a memory leak when setting a DBusError from a Windows
1186 error (fd.o #92721, Ralf Habacker)
1188 • On Windows, don't go into infinite recursion if we abort the process
1189 with backtraces enabled (fd.o #92721, Ralf Habacker)
1191 • Fix various failing tests, variously on Windows and cross-platform:
1192 · don't test system.conf features (users, groups) that only make sense
1193 on the system bus, which is not supported on Windows
1194 · don't call _dbus_warn() when we skip a test, since it is fatal
1195 · fix computation of expected <standard_session_servicedirs/>
1196 · when running TAP tests, translate newlines to Unix format, fixing
1197 cross-compiled tests under Wine on Linux
1198 · don't stress-test refcounting under Wine, where it's really slow
1199 · stop assuming that a message looped-back to the test will be received
1201 · skip some system bus tests on Windows since they make no sense there
1202 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
1204 D-Bus 1.10.2 (2015-10-26)
1207 The “worst pies in London” release.
1211 • Correct error handling for activation: if there are multiple attempts
1212 to activate the same service and it fails immediately, the first attempt
1213 would get the correct reply, but the rest would time out. We now send
1214 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
1216 • If BecomeMonitor is called with a syntactically invalid match rule,
1217 don't crash with an assertion failure, fixing a regression in 1.9.10.
1218 This was not exploitable as a denial of service, because the check
1219 for a privileged user is done first. (fd.o #92298, Simon McVittie)
1221 • On Linux with --enable-user-session, add the bus address to the
1222 environment of systemd services for better backwards compatibility
1223 (fd.o #92612, Jan Alexander Steffens)
1225 • On Windows, fix the logic for replacing the installation prefix
1226 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
1228 • On Windows, if installed in the conventional layout with ${prefix}/etc
1229 and ${prefix}/share, use relative paths between bus configuration files
1230 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
1232 • Make more of the regression tests pass in Windows builds (fd.o #92538,
1235 D-Bus 1.10.0 (2015-08-25)
1240 This is a new stable branch, recommended for use in OS distributions.
1244 • distribute test/tap-test.sh.in, even if the tarball was built without
1245 tests enabled (fd.o #91684, Simon McVittie)
1246 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
1248 Summary of major changes since 1.8.0:
1250 • The basic setup for the well-known system and session buses is
1251 now done in read-only files in ${datadir} (normally /usr/share).
1252 See the NEWS entry for 1.9.18 for details.
1254 • AppArmor integration has been merged, with features similar to the
1255 pre-existing SELinux integration. It is mostly compatible with the
1256 patches previously shipped by Ubuntu, with one significant change:
1257 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
1258 by GetConnectionCredentials and was not included.
1260 • The --enable-user-session configure option can be enabled
1261 by OS integrators intending to use systemd to provide a session bus
1262 per user (in effect, treating all concurrent graphical and non-graphical
1263 login sessions as one large session).
1265 • The new listenable address mode "unix:runtime=yes" listens on
1266 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
1267 user session. libdbus and "dbus-launch --autolaunch" will connect to
1268 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
1271 • All executables are now dynamically linked to libdbus-1.
1272 Previously, some executables, most notably dbus-daemon, were statically
1273 linked to a specially-compiled variant of libdbus. This results in
1274 various private functions in the _dbus namespace being exposed by the
1275 shared library. These are not API, and must not be used outside
1276 the dbus source tree.
1278 • On platforms with ELF symbol versioning, all public symbols
1279 are versioned LIBDBUS_1_3.
1283 • org.freedesktop.DBus.GetConnectionCredentials returns
1284 LinuxSecurityLabel where supported
1285 • org.freedesktop.DBus.Monitoring interface (privileged)
1286 · BecomeMonitor method supersedes match rules with eavesdrop=true,
1287 which are now deprecated
1288 • org.freedesktop.DBus.Stats interface (semi-privileged)
1289 · now enabled by default
1290 · new GetAllMatchRules method
1291 • org.freedesktop.DBus.Verbose interface (not normally compiled)
1292 · toggles the effect of DBUS_VERBOSE
1297 • dbus-update-activation-environment
1299 New optional dependencies:
1301 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
1302 • Complete documentation requires Ducktype and yelp-tools
1303 • Full test coverage requires GLib 2.36 and PyGI
1304 • AppArmor integration requires libapparmor and optionally libaudit
1306 Dependencies removed:
1310 D-Bus 1.9.20 (2015-08-06)
1313 The “Remember Tomorrow” release.
1315 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
1320 • Don't second-guess what the ABI of poll() is, allowing it to be used
1321 on Integrity RTOS and other unusual platforms (fd.o #90314;
1322 Rolland Dudemaine, Simon McVittie)
1324 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
1325 both enabled (fd.o #89225, Simon McVittie)
1327 • Log audit events for AppArmor/SELinux policy violations whenever
1328 we have CAP_AUDIT_WRITE, even if not the system bus
1329 (fd.o #83856, Laurent Bigonville)
1331 D-Bus 1.9.18 (2015-07-21)
1334 The “Pirate Elite” release.
1336 Configuration changes:
1338 • The basic setup for the well-known system and session buses is now done
1339 in read-only files in ${datadir}, moving a step closer to systems
1340 that can operate with an empty /etc directory. In increasing order
1343 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
1344 the default message policies.
1345 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
1346 dbus still installs a trivial version of each, for documentation
1347 purposes; putting configuration directives in these files is deprecated.
1348 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
1349 to install "drop-in" configuration snippets (any packages
1350 using those directories should explicitly depend on at least this
1352 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
1353 or third-party software to install "drop-in" configuration snippets
1354 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
1357 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
1358 and "s*" refers to either system or session as appropriate.
1360 (fd.o #89280, Dimitri John Ledkov)
1364 • Fix a memory leak when GetConnectionCredentials() succeeds
1365 (fd.o #91008, Jacek Bukarewicz)
1367 • Ensure that dbus-monitor does not reply to messages intended for others,
1368 resulting in its own disconnection (fd.o #90952, Simon McVittie)
1370 D-Bus 1.9.16 (2015-05-14)
1373 The “titanium barns” release.
1377 • Automake 1.13 is now required when compiling from git or modifying
1382 • On Unix platforms, change the default configuration for the session bus
1383 to only allow EXTERNAL authentication (secure kernel-mediated
1384 credentials-passing), as was already done for the system bus.
1386 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
1387 unpredictable pseudo-random numbers.
1389 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
1390 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1391 NFS or similar, you will need to reconfigure the session bus to accept
1392 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1395 (fd.o #90414, Simon McVittie)
1397 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1398 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1399 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1400 occurs, instead of silently falling back to low-entropy pseudorandom
1401 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1405 • Add dbus_message_iter_get_element_count()
1406 (fd.o #30350; Christian Dywan, Simon McVittie)
1408 • Introduce new internal DBusSocket and DBusPollable types so we can
1409 stop treating the Windows SOCKET type as if it was int. DBusSocket
1410 is specifically a socket, cross-platform. DBusPollable is whatever
1411 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1412 (fd.o #89444; Ralf Habacker, Simon McVittie)
1414 • All regression tests now output TAP <https://testanything.org/>
1415 (fd.o #89846, Simon McVittie)
1417 • Internal APIs consistently use signed values for timestamps
1418 (fd.o #18494, Peter McCurdy)
1420 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1421 (fd.o #88812, Simon McVittie)
1423 • Clean up a lot of compiler warnings
1424 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1428 • Add locking to DBusCounter's reference count and notify function
1429 (fd.o #89297, Adrian Szyndela)
1431 • Ensure that DBusTransport's reference count is protected by the
1432 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1434 • Correctly release DBusServer mutex before early-return if we run out
1435 of memory while copying authentication mechanisms (fd.o #90021,
1438 • Make dbus-test-tool and dbus-update-activation-environment portable
1439 to Windows (fd.o #90089, Ralf Habacker)
1441 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1442 Ralf Habacker, Simon McVittie)
1444 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1447 • Clean up some memory and fd leaks in test code and tools
1448 (fd.o #90021, Ralf Habacker)
1450 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1451 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1453 • CMake generates a versioned shared library even if the revision is 0,
1454 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1456 D-Bus 1.9.14 (2015-03-02)
1459 The “don't stand in the poison cloud” release.
1463 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1464 were previously linked to a static version of libdbus.
1466 • The tests no longer require dbus-glib in order to exercise the libdbus
1467 shared library; they are always linked to libdbus now.
1469 Build-time configuration:
1471 • The new --enable-user-session option, off by default, can be enabled
1472 by OS integrators intending to use systemd to provide a session bus
1473 per user (in effect, treating all concurrent graphical and non-graphical
1474 login sessions as one large session)
1478 • All executables are now linked dynamically to libdbus.
1479 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1481 • On platforms that support them (GNU libc and possibly others),
1482 libdbus now has versioned symbols for its public API.
1483 All public symbols (visible in the header files) are currently
1484 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1485 dbus_internal have a version that changes with each release, and
1486 must not be used by applications. (also fd.o #83115)
1488 • New listenable address mode "unix:runtime=yes" which listens on
1489 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1490 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1492 • Add optional systemd units for a per-user bus listening on
1493 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1495 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1496 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1499 • New dbus-update-activation-environment tool uploads environment
1500 variables to "dbus-daemon --session" and optionally "systemd --user",
1501 primarily as a way to keep the per-user bus compatible with
1502 distributions' existing X11 login scripts (also fd.o #61301)
1504 • <includedir/> elements in dbus-daemon configuration are now silently
1505 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1507 • Add microsecond-resolution timestamps to the default output of
1508 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1512 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1513 (fd.o #89222, Simon McVittie)
1515 D-Bus 1.9.12 (2015-02-19)
1518 The “monster lasagna” release.
1522 • Ducktype and yelp-tools are now required to build complete documentation
1523 (they are optional for normal builds).
1527 • D-Bus Specification version 0.26
1528 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1529 · document the BecomeMonitor method
1531 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1532 (fd.o #89041; Tyler Hicks, Simon McVittie)
1534 • On Linux, add support for AppArmor mediation of message sending and
1535 receiving and name ownership (paralleling existing SELinux mediation
1536 support), and eavesdropping (a new check, currently AppArmor-specific)
1537 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1539 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1540 that have printable ASCII contents; we previously only did this for
1541 unterminated bytestrings (fd.o #89109, Simon McVittie)
1543 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1545 • On Windows, add WindowsSID to GetConnectionCredentials
1546 (fd.o #54445, Ralf Habacker)
1548 • Improve clarity of dbus-monitor --profile output and add more columns
1549 (fd.o #89165, Ralf Habacker)
1551 • Add a man page for dbus-test-tool, and build it under CMake as well
1552 as Autotools (fd.o#89086, Simon McVittie)
1554 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1555 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1556 (fd.o #88896, Ralf Habacker)
1560 • Reduce the number of file descriptors used in the fd-passing test,
1561 avoiding failure under the default Linux fd limit, and automatically
1562 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1564 D-Bus 1.9.10 (2015-02-09)
1567 The “sad cyborgs” release.
1569 Security fixes merged from 1.8.16:
1571 • Do not allow non-uid-0 processes to send forged ActivationFailure
1572 messages. On Linux systems with systemd activation, this would
1573 allow a local denial of service: unprivileged processes could
1574 flood the bus with these forged messages, winning the race with
1575 the actual service activation and causing an error reply
1576 to be sent back when service auto-activation was requested.
1577 This does not prevent the real service from being started,
1578 so the attack only works while the real service is not running.
1579 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1583 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1584 similar tools receive messages without altering the security properties
1585 of the system bus, by calling the new BecomeMonitor method on a
1586 private connection. This bypasses the normal <allow> and <deny> rules
1587 entirely, so to preserve normal message-privacy assumptions, only root
1588 is allowed to do this on the system bus. Restricted environments,
1589 such as Linux with LSMs, should lock down access to the Monitoring
1590 interface. (fd.o #46787, Simon McVittie)
1592 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1593 dbus-daemon supports it and access permissions allow it.
1594 It still supports the previous approach ("eavesdropping" match rules)
1595 for compatibility with older bus daemons. (fd.o #46787, Simon)
1597 • dbus-monitor can now log the message stream as binary data for later
1598 analysis, with either no extra framing beyond the normal D-Bus headers,
1599 or libpcap-compatible framing treating each D-Bus message
1600 as a captured packet. (fd.o #46787, Simon)
1604 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1606 • On Unix, forcibly terminate regression tests after 60 seconds to
1607 prevent them from blocking continuous integration frameworks
1608 (fd.o #46787, Simon)
1610 D-Bus 1.9.8 (2015-02-03)
1613 The “all the types of precipitation” release.
1617 • full test coverage now requires GLib 2.36
1618 • full test coverage now requires PyGI (PyGObject 3,
1619 "import gi.repository.GObject") instead of the
1620 obsolete PyGObject 2 ("import gobject")
1624 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1626 • better regression test coverage, including systemd activation
1627 (fd.o #57952, #88810; Simon McVittie)
1631 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1632 turned off (fd.o #88808, Simon McVittie)
1634 • TCP sockets on Windows no longer fail to listen approximately 1 time
1635 in 256, caused by a logic error that should have always made it fail but
1636 was mitigated by incorrect endianness for the port number
1637 (fd.o #87999, Ralf Habacker)
1639 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1641 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1642 previous 64, completing a previous fix which only worked under
1643 Autotools (fd.o #71297, Ralf Habacker)
1645 • on Windows, if the IP family is unspecified only use IPv4,
1646 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1648 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1650 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1652 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1655 D-Bus 1.9.6 (2015-01-05)
1658 The “I do have a bread knife” release.
1662 • Do not allow calls to UpdateActivationEnvironment from uids other than
1663 the uid of the dbus-daemon. If a system service installs unsafe
1664 security policy rules that allow arbitrary method calls
1665 (such as CVE-2014-8148) then this prevents memory consumption and
1666 possible privilege escalation via UpdateActivationEnvironment.
1668 We believe that in practice, privilege escalation here is avoided
1669 by dbus-daemon-launch-helper sanitizing its environment; but
1670 it seems better to be safe.
1672 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1673 on object paths other than /org/freedesktop/DBus. Some system services
1674 install unsafe security policy rules that allow arbitrary method calls
1675 to any destination, method and interface with a specified object path;
1676 while less bad than allowing arbitrary method calls, these security
1677 policies are still harmful, since dbus-daemon normally offers the
1678 same API on all object paths and other system services might behave
1683 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1684 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1686 D-Bus 1.9.4 (2014-11-24)
1689 The “extra-sturdy caramel” release.
1693 • Partially revert the CVE-2014-3639 patch by increasing the default
1694 authentication timeout on the system bus from 5 seconds back to 30
1695 seconds, since this has been reported to cause boot regressions for
1696 some users, mostly with parallel boot (systemd) on slower hardware.
1698 On fast systems where local users are considered particularly hostile,
1699 administrators can return to the 5 second timeout (or any other value
1700 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1703 <limit name="auth_timeout">5000</limit>
1706 (fd.o #86431, Simon McVittie)
1708 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1709 (fd.o #86431, Simon McVittie)
1711 • Send back an AccessDenied error if the addressed recipient is not allowed
1712 to receive a message (and in builds with assertions enabled, don't
1713 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1715 D-Bus 1.9.2 (2014-11-10)
1718 The “structurally unsound flapjack” release.
1722 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1723 so that CVE-2014-3636 part A cannot exhaust the system bus'
1724 file descriptors, completing the incomplete fix in 1.8.8.
1725 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1729 • D-Bus Specification version 0.25
1730 · new value 'const' for EmitsChangedSignal annotation

1738 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1739 (fd.o #83449, Simon McVittie)
1741 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1742 useful for debugging and performance testing:
1743 · dbus-test-tool spam: send repeated messages
1744 · dbus-test-tool echo: send an empty reply for all method calls
1745 · dbus-test-tool black-hole: do not reply to method calls
1746 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1748 • Add support for process ID in credentials-passing on NetBSD
1749 (fd.o #69702, Patrick Welche)
1751 • Add an example script to find potentially undesired match rules
1752 (fd.o #84598, Alban Crequy)
1754 • Document the central assumption that makes our use of credentials-passing
1755 secure (fd.o #83499, Simon McVittie)
1757 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1758 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1763 • Use a less confusing NoReply message when disconnected with a reply pending
1764 (fd.o #76112, Simon McVittie)
1766 • Make the .pc file relocatable by letting pkg-config do all variable
1767 expansion itself (fd.o #75858, Руслан Ижбулатов)
1769 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1770 (fd.o #85563, Patrick Welche)
1772 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1774 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1775 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1777 • Do not fail the tests if a parent process has leaked non-close-on-exec
1778 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1780 • Do not fail the tests on Unix platforms with incomplete
1781 credentials-passing support, but do fail if we can't pass credentials
1782 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1783 (fd.o #69702, Simon McVittie)
1785 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1786 when building with cmake, and expand test coverage there
1787 (fd.o #73689; Ralf Habacker, Simon McVittie)
1789 D-Bus 1.9.0 (2014-10-01)
1792 The “tiered cheeses” release.
1796 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1797 requires either the libsystemd or libsd-daemon shared library, dropping the
1798 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1800 Build-time configuration changes:
1802 • The Stats interface is now enabled by default, and locked-down to
1803 root-only on the system bus. Configure with --disable-stats
1804 to disable it altogether on memory- or disk-constrained systems,
1805 or see ${docdir}/examples/ to open it up to non-root users on the
1806 system bus or restrict access on the session bus.
1807 (fd.o #80759; Simon McVittie, Alban Crequy)
1809 • The CMake build system now builds the same shared library name as Autotools
1810 on at least Linux and Windows:
1811 - on Linux (and perhaps other Unix platforms), it previously built
1812 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1813 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1814 - on Windows, it previously built either libdbus-1.dll (release) or
1815 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1816 libdbus-1.dll for compatibility with older applications.

1823 · explicitly say that most message types never expect a reply
1824 regardles of whether they have NO_REPLY_EXPECTED
1825 (fd.o #75749, Simon McVittie)
1827 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
1828 initial latency (fd.o #75544, Matt Hoosier)
1830 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
1831 (fd.o #69702, Patrick Welche)
1833 • in dbus-monitor, print more information about file descriptors
1834 (fd.o #80603, Alban Crequy)
1836 • do not install system bus configuration if built for Windows
1837 (fd.o #83583; Ralf Habacker, Simon McVittie)
1839 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
1841 • Add a regression test for file descriptor passing (fd.o #83622,
1846 • fix an incorrect error message if a Unix socket path is too long
1847 (fd.o #73887, Antoine Jacoutot)
1849 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
1850 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
1852 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
1853 in ps(1) (fd.o #69716, Chengwei Yang)
1855 • avoid calling poll() with timeout < -1, which is considered invalid
1856 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
1858 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
1859 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
1860 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
1862 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
1864 • Documentation improvements
1865 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
1867 • in dbus-monitor, do not leak file descriptors that we have monitored
1868 (fd.o #80603, Alban Crequy)
1870 • Set the close-on-exec flag for the inotify file descriptor, even
1871 if built with CMake or older libc (fd.o #73689, Simon McVittie)
1873 • Remove some LGPL code from the Windows dbus-daemon
1874 (fd.o #57272, Ralf Habacker)
1876 D-Bus 1.8.8 (2014-09-16)
1879 The "smashy smashy egg man" release.
1883 • Do not accept an extra fd in the padding of a cmsg message, which
1884 could lead to a 4-byte heap buffer overrun.
1885 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1887 • Reduce default for maximum Unix file descriptors passed per message
1888 from 1024 to 16, preventing a uid with the default maximum number of
1889 connections from exhausting the system bus' file descriptors under
1890 Linux's default rlimit. Distributors or system administrators with a
1891 more restrictive fd limit may wish to reduce these limits further.
1893 Additionally, on Linux this prevents a second denial of service
1894 in which the dbus-daemon can be made to exceed the maximum number
1895 of fds per sendmsg() and disconnect the process that would have
1897 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1899 • Disconnect connections that still have a fd pending unmarshalling after
1900 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1901 removing the possibility of creating an abusive connection that cannot be
1902 disconnected by setting up a circular reference to a connection's
1904 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1906 • Reduce default for maximum pending replies per connection from 8192 to 128,
1907 mitigating an algorithmic complexity denial-of-service attack
1908 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1910 • Reduce default for authentication timeout on the system bus from
1911 30 seconds to 5 seconds, avoiding denial of service by using up
1912 all unauthenticated connection slots; and when all unauthenticated
1913 connection slots are used up, make new connection attempts block
1914 instead of disconnecting them.
1915 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1919 • Check for libsystemd from systemd >= 209, falling back to
1920 the older separate libraries if not found (Umut Tezduyar Lindskog,
1923 • On Linux, use prctl() to disable core dumps from a test executable
1924 that deliberately raises SIGSEGV to test dbus-daemon's handling
1925 of that condition (fd.o #83772, Simon McVittie)
1927 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
1930 • Improve documentation for running tests on Windows (fd.o #41252,
1933 D-Bus 1.8.6 (2014-06-02)
1938 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1939 the message. This prevents an attack in which a malicious client can
1940 make dbus-daemon disconnect a system service, which is a local
1942 (fd.o #80163, CVE-2014-3532; Alban Crequy)
1944 • Track remaining Unix file descriptors correctly when more than one
1945 message in quick succession contains fds. This prevents another attack
1946 in which a malicious client can make dbus-daemon disconnect a system
1948 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
1949 Simon McVittie, Alban Crequy)
1953 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
1954 attach to a session, kill the dbus-daemon as intended
1955 (fd.o #74698, Роман Донченко)
1957 D-Bus 1.8.4 (2014-06-10)
1962 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1963 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1964 Additionally, in highly unusual environments the same flaw could lead to
1965 a side channel between processes that should not be able to communicate.
1966 (CVE-2014-3477, fd.o #78979)
1968 D-Bus 1.8.2 (2014-04-30)
1971 The “nobody wants red” release.
1975 • in the CMake build system, add some hints for Linux users cross-compiling
1976 Windows D-Bus binaries to be able to run tests under Wine
1977 (fd.o #41252, Ralf Habacker)
1979 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
1983 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
1984 to /var/lib/dbus/machine-id instead of generating an entirely new ID
1985 (fd.o #77941, Simon McVittie)
1987 • if dbus-launch receives an X error very quickly, do not kill
1988 unrelated processes (fd.o #74698, Роман Донченко)
1990 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
1991 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
1993 • cope with \r\n newlines in regression tests, since on Windows,
1994 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
1996 D-Bus 1.8.0 (2014-01-20)
1999 The “Wolverine distrusts my printer” release.
2001 This starts a new stable branch. The 1.6.x branch is now considered to be
2002 outdated, and will only receive fixes for serious bugs such as security
2003 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
2004 are unlikely to get any more releases, but if distributors still need to
2005 support them, please share security patches via upstream.
2007 Summary of changes since 1.6.x:
2009 • libdbus always behaves as if dbus_threads_init_default() had been called
2010 (thread-safety by default)
2011 • new dbus-run-session tool, replacing certain misuses of dbus-launch
2012 • dbus-monitor can talk to outdated versions of dbus-daemon again
2013 • new org.freedesktop.DBus.GetConnectionCredentials method
2014 • GetConnectionUnixProcessID also works correctly on Windows, returning
2015 the Windows process ID
2016 • GetConnectionWindowsSID returns the correct SID on Windows
2017 • expat is required, libxml2 can no longer be used as a substitute
2018 • the userDB cache is required, and cannot be disabled
2019 • a 64-bit integer type (either int, long, long long or _int64) is required
2020 • better systemd-journald integration on Linux
2021 • fixed long-standing fd and array leaks when failing to parse a message
2022 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
2023 when using certain object-path allocation patterns, notably in Avahi
2024 • better defaults for Windows support
2025 • better CMake support
2026 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
2027 • the source language for the man pages is now Docbook XML
2029 Enhancements since 1.7.10:
2031 • Enhance the CMake build system to check for GLib and compile/run
2032 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
2036 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
2039 • fix compilation of systemd journal support on older systemd versions where
2040 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
2042 • fix compilation on older MSVC versions by including stdlib.h
2043 (fd.o #73455, Ralf Habacker)
2045 • Allow <allow_anonymous/> to appear in an included configuration file
2046 (fd.o #73475, Matt Hoosier)
2048 Test behaviour changes since 1.7.10:
2050 • If the tests crash with an assertion failure, they no longer default to
2051 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
2052 environment if you want the old behaviour.
2054 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
2055 can be run with an external dbus-daemon by setting
2056 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
2057 an unusually-configured dbus-daemon are skipped.
2059 D-Bus 1.7.10 (2014-01-06)
2062 The “weighted companion cube” release.
2064 This is a release candidate for D-Bus 1.8.
2066 D-Bus Specification 0.23:
2068 • don't require messages with no INTERFACE to be dispatched
2069 (fd.o #68597, Simon McVittie)
2071 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
2074 • define "listenable" and "connectable" addresses, and discuss
2075 the difference (fd.o #61303, Simon McVittie)
2079 • support printing Unix file descriptors in dbus-send, dbus-monitor
2080 (fd.o #70592, Robert Ancell)
2082 • don't install systemd units if --disable-systemd is given
2083 (fd.o #71818, Chengwei Yang)
2087 • don't leak memory on out-of-memory while listing activatable or
2088 active services (fd.o #71526, Radoslaw Pajak)
2090 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
2092 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
2094 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
2095 and DBUS__SEND_MSG are numerically equal to their values in the
2096 reference policy (fd.o #88719, osmond sun)
2098 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
2099 (fd.o #71366, Matt Fischer)
2101 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
2102 winsock2.h (fd.o #71405, Matt Fischer)
2104 • do not return failure from _dbus_read_nonce() with no error set,
2105 preventing a potential crash (fd.o #72298, Chengwei Yang)
2107 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
2108 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
2110 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
2111 which doesn't do anything anyway on at least Linux and FreeBSD
2112 (fd.o #69492, Simon McVittie)
2114 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
2115 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
2116 for credentials more correctly (fd.o #69492, Simon McVittie)
2118 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
2119 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
2122 • refresh cached policy rules for existing connections when bus
2123 configuration changes (fd.o #39463, Chengwei Yang)
2125 D-Bus 1.7.8 (2013-11-01)
2128 The “extreme hills” release.
2132 • If systemd support is enabled, libsystemd-journal is now required.
2136 • When activating a non-systemd service under systemd, annotate its
2137 stdout/stderr with its bus name in the Journal. Known limitation:
2138 because the socket is opened before forking, the process will still be
2139 logged as if it had dbus-daemon's process ID and user ID.
2140 (fd.o #68559, Chengwei Yang)
2142 • Document more configuration elements in dbus-daemon(1)
2143 (fd.o #69125, Chengwei Yang)
2147 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
2148 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
2150 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
2151 disallowed method calls to the audit log, fixing a regression in 1.7.6
2152 (fd.o #49062, Colin Walters)
2154 • path_namespace='/' in match rules incorrectly matched nothing; it
2155 now matches everything. (fd.o #70799, Simon McVittie)
2157 D-Bus 1.7.6 (2013-10-09)
2160 The “CSI Shrewsbury” release.
2162 Build-time configuration changes:
2164 • Directory change notification via dnotify on Linux is no longer
2165 supported; it hadn't compiled successfully since 2010 in any case.
2166 If you don't have inotify (Linux) or kqueue (*BSD), you will need
2167 to send SIGHUP to the dbus-daemon when its configuration changes.
2168 (fd.o #33001, Chengwei Yang)
2170 • Compiling with --disable-userdb-cache is no longer supported;
2171 it didn't work since at least 2008, and would lead to an extremely
2172 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
2175 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
2176 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
2177 with the Autotools build system. (fd.o #66142, Chengwei Yang)
2179 • --with-valgrind=auto enables Valgrind instrumentation if and only if
2180 valgrind headers are available. The default is still --with-valgrind=no.
2181 (fd.o #56925, Simon McVittie)
2185 • Platforms with no 64-bit integer type are no longer supported.
2186 (fd.o #65429, Simon McVittie)
2188 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
2190 • Full test coverage no longer requires dbus-glib, although the tests do not
2191 exercise the shared library (only a static copy) if dbus-glib is missing.
2192 (fd.o #68852, Simon McVittie)
2196 • D-Bus Specification 0.22
2197 · Document GetAdtAuditSessionData() and
2198 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
2199 · Fix example .service file (fd.o #66481, Chengwei Yang)
2200 · Don't claim D-Bus is "low-latency" (lower than what?), just
2201 give factual statements about it supporting async use
2202 (fd.o #65141, Justin Lee)
2203 · Document the contents of .service files, and the fact that
2204 system services' filenames are constrained
2205 (fd.o #66608; Simon McVittie, Chengwei Yang)
2207 • Be thread-safe by default on all platforms, even if
2208 dbus_threads_init_default() has not been called. For compatibility with
2209 older libdbus, library users should continue to call
2210 dbus_threads_init_default(): it is harmless to do so.
2211 (fd.o #54972, Simon McVittie)
2213 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
2215 • New API: dbus_setenv(), a simple wrapper around setenv().
2216 Note that this is not thread-safe. (fd.o #39196, Simon)
2218 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
2219 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
2220 (connect to a given bus, like dbus-monitor --address=ADDRESS).
2221 dbus-send --address still exists for backwards compatibility,
2222 but is no longer documented. (fd.o #48816, Andrey Mazo)
2225 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
2230 • Avoid an infinite busy-loop if a signal interrupts waitpid()
2231 (fd.o #68945, Simon McVittie)
2233 • Clean up memory for parent nodes when objects are unexported
2234 (fd.o #60176, Thomas Fitzsimmons)
2236 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
2237 documented. Previously, it assumed its second parameter was TRUE.
2238 (fd.o #69165, Chengwei Yang)
2240 • Escape addresses containing non-ASCII characters correctly
2241 (fd.o #53499, Chengwei Yang)
2243 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
2245 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
2246 (fd.o #65923, Chengwei Yang)
2248 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
2249 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
2251 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
2252 that was never va_start()ed (fd.o #66300, Chengwei Yang)
2254 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
2256 • fix a regression test on platforms with strict alignment (fd.o #67279,
2259 • Avoid calling function parameters "interface" since certain Windows headers
2260 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
2262 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
2264 • Various thread-safety improvements to static variables (fd.o #68610,
2267 • Make "make -j check" work (fd.o #68852, Simon McVittie)
2269 • Fix a NULL pointer dereference on an unlikely error path
2270 (fd.o #69327, Sviatoslav Chagaev)
2272 • Improve valgrind memory pool tracking (fd.o #69326,
2275 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
2278 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
2279 (fd.o #66107, Chengwei Yang)
2282 · If accept4() fails with EINVAL, as it can on older Linux kernels
2283 with newer glibc, try accept() instead of going into a busy-loop.
2284 (fd.o #69026, Chengwei Yang)

2334 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
2335 of service for system services. Vulnerability reported by Alexandru Cornea.
2340 • The Windows version of libdbus now contains a C++ source file, used
2341 to provide global initialization when the library is loaded.
2342 gcc (mingw*) users should ensure that g++ is also installed.
2344 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
2345 and was never the recommended option) has been removed. Expat is now a
2350 • It should now be safe to call dbus_threads_init_default() from any thread,
2351 at any time. Authors of loadable modules and plugins that use libdbus
2352 should consider doing so during initialization.
2353 (fd.o #54972, Simon McVittie)
2355 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
2359 · dbus-run-session: experimental new tool to start a temporary D-Bus
2360 session, e.g. for regression tests or a text console, replacing
2361 certain uses of dbus-launch which weren't really correct
2362 (fd.o #39196, Simon)
2366 • In dbus-daemon, don't crash if a .service file starts with key=value

2373 · Fix an assertion failure if we try to activate systemd services before
2374 systemd connects to the bus (fd.o #50199, Chengwei Yang)
2375 · Avoid compiler warnings for ignoring the return from write()
2379 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/

2434 The "Disingenuous Assertions" release.
2436 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
2437 remains the recommended version for long-term-supported distributions
2438 or the upcoming GNOME 3.8 release.
2440 Build-time configuration changes:
2442 • The --with-dbus-session-bus-default-address configure option is no longer
2443 supported. Use the new --with-dbus-session-bus-connect-address and
2444 --with-dbus-session-bus-listen-address options instead. On Windows, you
2445 usually want them to have the same argument; on Unix, the defaults are
2448 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2449 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2450 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2452 • cmake/cross-compile.sh has been removed. Instead, please use a
2453 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2454 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2455 as documented in "info automake Cross-Compilation", and set
2456 PKG_CONFIG_PATH appropriately.

2467 implements o.fd.DBus (fd.o #51865, Colin Walters)
2468 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
2469 · stop claiming that all basic types work just like INT32 (strings don't!)
2471 • The "source code" for the man pages is now Docbook XML, eliminating
2472 the outdated duplicate copies used when building with CMake.
2473 (fd.o #59805; Ralf Habacker, Simon McVittie)
2477 • In the activation helper, when compiled for tests, do not reset the system
2478 bus address, fixing the regression tests. (fd.o #52202, Simon)
2480 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
2481 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
2483 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

2502 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
2505 · The default session bus listening and connecting address is now
2506 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2507 and GDBus "out of the box". Use the configure options and cmake variables
2508 described above if you require a different autolaunch scope.
2509 (fd.o #38201, Simon McVittie)
2510 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
2512 • Create session.d, system.d directories under CMake (fd.o #41319,
2515 D-Bus 1.6.8 (2012-09-28)
2518 The "Fix one thing, break another" release.
2520 • Follow up to CVE-2012-3524: The additional hardening
2521 work to use __secure_getenv() as a followup to bug #52202
2522 broke certain configurations of gnome-keyring. Given
2523 the difficulty of making this work without extensive
2524 changes to gnome-keyring, use of __secure_getenv() is

2568 • Disconnect "developer mode" (assertions, verbose mode etc.) from
2569 Automake maintainer mode. D-Bus developers should now configure with
2570 --enable-developer. Automake maintainer mode is now on by default;
2571 distributions can disable it with --disable-maintainer-mode.
2572 (fd.o #34671, Simon McVittie)
2574 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,

2578 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
2580 D-Bus 1.6.0 (2012-06-05)
2583 The “soul of this machine has improved” release.
2585 This version starts a new stable branch of D-Bus: only bug fixes will
2586 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.

2647 (fd.o #39549, Simon McVittie)
2649 • Turn DBusBasicValue into public API so bindings don't need to invent their
2650 own "union of everything" type (fd.o #11191, Simon McVittie)

2662 (fd.o #47321, Andoni Morales Alastruey)
2664 D-Bus 1.5.10 (2012-02-21)
2667 The "fire in Delerium" release.
2669 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2670 and SUSv2) is now required.
2672 • D-Bus Specification 0.19:
2673 · Formally define unique connection names and well-known bus names,
2674 and document best practices for interface, bus, member and error names,
2675 and object paths (fd.o #37095, Simon McVittie)
2676 · Document the search path for session and system services on Unix, and
2677 where they should be installed by build systems (fd.o #21620, fd.o #35306;
2679 · Document the systemd transport (fd.o #35232, Lennart Poettering)
2681 • Make dbus_threads_init() use the same built-in threading implementation
2682 as dbus_threads_init_default(); the user-specified primitives that it
2683 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
2685 • Allow all configured auth mechanisms, not just one (fd.o #45106,
2688 • Improve cmake build system (Ralf Habacker):
2689 · simplify XML parser dependencies (fd.o #41027)
2690 · generate build timestamp (fd.o #41029)
2691 · only create batch files on Windows
2692 · fix option and cache syntax
2693 · add help-options target
2694 · share dbus-arch-deps.h.in with autotools rather than having our
2695 own version (fd.o #41033)
2697 • Build tests successfully with older GLib, as found in e.g. Debian 6
2698 (fd.o #41219, Simon McVittie)
2700 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
2702 • Build documentation correctly if man2html doesn't support filenames on
2703 its command-line (fd.o #43875, Jack Nagel)
2705 • Improve test coverage. To get even more coverage, run the tests with
2706 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
2708 • Reduce the size of the shared library by moving functionality only used
2709 by dbus-daemon, tests etc. into their internal library and deleting
2710 unused code (fd.o #34976, #39759; Simon McVittie)
2712 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2713 setups where the default configuration must include <pidfile/> to avoid
2714 breaking traditional init, but the pid file is in fact unnecessary; use
2715 it under systemd to improve startup time a bit (fd.o #45520,
2718 • Optionally (if configured --with-valgrind) add instrumentation to debug
2719 libdbus and associated tools more meaningfully under Valgrind
2720 (fd.o #37286, Simon McVittie)

2724 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
2726 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
2727 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
2728 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
2731 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
2735 · Replace our broken reimplementation of recursive mutexes, which has
2736 been broken since 2006, with an ordinary pthreads recursive mutex
2737 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2738 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2739 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2740 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2741 · When running under systemd, use it instead of ConsoleKit to check
2742 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2743 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2744 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2745 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2746 (fd.o #41218, Simon McVittie)
2747 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2748 helper doesn't obey environment variables to avoid privilege escalation
2749 attacks, so make the system bus follow the same rules
2750 (fd.o #21620, Simon McVittie)
2753 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2754 Jesper Dam, Ralf Habacker)
2755 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
2758 D-Bus 1.5.8 (2011-09-21)

2763 In addition to dead code removal and refactoring, this release contains all
2764 of the bugfixes from 1.4.16.
2766 • Clean up dead code, and make more warnings fatal in development builds
2767 (fd.o #39231, fd.o #41012; Simon McVittie)
2769 • If full test coverage is requested via --enable-tests, strictly require
2770 Python, pygobject and dbus-python, which are required by some tests; if not,
2771 and Python is missing, skip those tests rather than failing
2772 (fd.o #37847, Simon McVittie)
2774 • When using cmake, provide the same version-info API in the installed headers
2775 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2777 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
2779 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)

2786 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2787 (fd.o #39879, Chris Mayo)
2789 • Fix a small memory leak, and a failure to report errors, when updating
2790 a service file entry for activation (fd.o #39230, Simon McVittie)
2793 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2794 Brian Cameron, Simon McVittie)
2795 · On systems that use libcap-ng but not systemd, drop supplemental groups
2796 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2797 · Make the cmake build work again on GNU platforms (fd.o #29228,

2800 like Solaris (fd.o #40313, Dagobert Michelsen)
2801 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2802 (fd.o #40235, Simon McVittie)
2803 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2804 (fd.o #39987, Simon McVittie)
2805 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2806 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2809 · Fix compilation on MSVC, which doesn't understand "inline" with its
2810 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2811 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2812 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2814 D-Bus 1.5.6 (2011-07-29)
2817 The "weird, gravy-like aftertaste" release.
2819 In addition to new features and refactoring, this release contains all of the
2820 bugfixes from 1.4.14.
2822 Potentially incompatible (Bustle and similar debugging tools will need
2823 changes to work as intended):
2825 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2826 different recipient) by mistake: eavesdroppers must now opt-in to this
2827 behaviour by putting "eavesdrop='true'" in the match rule, which will
2828 not have any practical effect on buses where eavesdropping is not allowed
2829 (fd.o #37890, Cosimo Alfarano)
2833 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2834 Cosimo Alfarano, Simon McVittie)
2835 · add the "eavesdrop" keyword to match rules
2836 · define eavesdropping, unicast messages and broadcast messages
2837 · stop claiming that match rules are needed to match unicast messages to you
2838 · promote the type system to be a top-level section
2840 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2841 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2842 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2844 • Consistently use atomic operations on everything that is ever manipulated
2845 via atomic ops, as was done for changes to DBusConnection's refcount in
2846 1.4.12 (fd.o #38005, Simon McVittie)
2848 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2851 • Make "make check" in a clean tree work, by not running tests until
2852 test data has been set up (fd.o #34405, Simon McVittie)
2854 • The dbus-daemon no longer busy-loops if it has a very large number of file
2855 descriptors (fd.o #23194, Simon McVittie)
2857 • Refactor message flow through dispatching to avoid locking violations if
2858 the bus daemon's message limit is hit; remove the per-connection link cache,
2859 which was meant to improve performance, but now reduces it (fd.o #34393,
2862 • Some cmake fixes (Ralf Habacker)
2864 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2865 Simon McVittie, Lennart Poettering)
2867 • Stop storing two extra byte order indicators in each D-Bus message
2868 (fd.o #38287, Simon McVittie)
2870 • Add an optional Stats interface which can be used to get statistics from
2871 a running dbus-daemon if enabled at configure time with --enable-stats
2872 (fd.o #34040, Simon McVittie)
2874 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2876 • Documentation (fd.o #36156, Simon McVittie):
2877 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2878 · install more documentation automatically, including man2html output
2879 · put dbus.devhelp in the right place (it must go in ${htmldir})
2882 · look for system services in /lib/dbus-1/system-services in addition to all
2883 the other well-known locations; note that this should always be /lib,
2884 even on platforms where shared libraries on the root FS would go in /lib64,
2885 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2886 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2888 • Windows-specific (Ralf Habacker):
2889 · fix use of a mutex for autolaunch server detection
2890 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2892 D-Bus 1.5.4 (2011-06-10)
2895 Security (local denial of service):
2897 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2898 local DoS if foreign-endian messages are relayed through the dbus-daemon
2899 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2900 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2904 • The constant to use for an infinite timeout now has a name,
2905 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2906 which can be used for source compatibility with older versions of libdbus.
2908 • If GLib and DBus-GLib are already installed, more tests will be built,
2909 providing better coverage. The new tests can also be installed via
2910 ./configure --enable-installed-tests
2911 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2915 • Consistently use atomic operations for the DBusConnection's refcount,
2916 fixing potential threading problems (fd.o #38005, Simon McVittie)
2918 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2919 small (300KiB on x86-64) and it frequently doesn't work in unusual
2920 toolchains. To optimize for minimum installed size, you should benchmark
2921 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2922 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2924 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2925 (fd.o #35880, Timothy Redaelli)
2927 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2928 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2930 • Windows-specific changes:
2931 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2933 D-Bus 1.5.2 (2011-06-01)
2936 The "Boar Hunter" release.
2938 Notes for distributors:
2940 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2941 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2942 toolchain supports it reliably, via something like:
2944 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2946 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2950 • D-Bus Specification v0.17
2951 · Reserve the extra characters used in signatures by GVariant
2952 (fd.o #34529, Simon McVittie)
2953 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2954 • Don't force -fPIE: distributions and libtool know better than we do whether
2955 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2956 • Allow --disable-gc-sections, in case your toolchain offers the
2957 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2958 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2959 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2960 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2961 • Ensure that maintainers upload documentation with the right permissions
2962 (fd.o #36130, Simon McVittie)

2967 • Log messages dropped due to quotas to syslog (fd.o #35358,
2969 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
2970 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
2971 (fd.o #35228, Lennart Poettering)
2972 • In the regression tests, don't report fds as "leaked" if they were open
2973 on startup (fd.o #35173, Simon McVittie)
2974 • Make dbus-monitor bail out if asked to monitor more than one bus,
2975 rather than silently using the last one (fd.o #26548, Will Thompson)
2976 • Clarify documentation (fd.o #35182, Simon McVittie)
2977 • Clean up minor dead code and some incorrect error handling
2978 (fd.o #33128, fd.o #29881; Simon McVittie)
2979 • Check that compiler options are supported before using them (fd.o #19681,
2982 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
2984 D-Bus 1.5.0 (2011-04-11)

2988 flying shark" release.
2990 • D-Bus Specification v0.16
2991 · Add support for path_namespace and arg0namespace in match rules
2992 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
2993 · Make argNpath support object paths, not just object-path-like strings,
2994 and document it better (fd.o #31818, Will Thompson)
2995 • Let the bus daemon implement more than one interface (fd.o #33757,
2997 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2999 • Require user intervention to compile with missing 64-bit support
3000 (fd.o #35114, Simon McVittie)
3001 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
3002 • Raise UnknownObject instead of UnknownMethod for calls to methods on
3003 paths that are not part of the object tree, and UnknownInterface for calls

3009 The "It's like the beginning of a lobster" release.
3011 • Rename configure.in to configure.ac, and update it to modern conventions
3012 (fd.o #32245; Javier Jardón, Simon McVittie)
3013 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
3015 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
3016 --disable-x11-autolaunch configure option to prevent it altogether
3017 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
3018 • Install the documentation, and an index for Devhelp (fd.o #13495,
3019 Debian #454142; Simon McVittie, Matthias Clasen)
3020 • If checks are not disabled, check validity of string-like types and
3021 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
3022 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
3023 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
3024 • Break up a huge conditional in config-parser so gcov can produce coverage
3025 data (fd.o #10887, Simon McVittie)
3026 • List which parts of the Desktop Entry specification are applicable to
3027 .service files (fd.o #19159, Sven Herzberg)
3028 • Don't suppress service activation if two services have the same Exec=
3029 (fd.o #35750, Colin Walters)

3039 The "1, 2, miss a few, 99, 100" release.
3041 • Remove unfinished changes intended to support GTest-based tests,
3042 which were mistakenly included in 1.4.4
3044 D-Bus 1.4.4 (2010-02-17)
3047 • Switch back to using even micro versions for stable releases; 1.4.1
3048 should have been called 1.4.2, so skip that version number
3049 • Don't leave bad file descriptors being watched when spawning processes,
3050 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
3051 also LP#656134, LP#680444, LP#713157)
3052 • Check for MSG_NOSIGNAL correctly
3053 • Fix failure to detect abstract socket support (fd.o #29895)
3054 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
3055 (fd.o #32262, NB#180486)

3085 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
3086 crash the bus. The existing restriction to 64-levels of nesting previously
3087 only applied to the static type signature; now it also applies to dynamic
3088 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
3090 • OS X portability fixes, including launchd support.
