1 dbus 1.12.18 (UNRELEASED)
2 =========================
6 • Fix a crash when the dbus-daemon is terminated while one or more
7 monitors are active (dbus#291, dbus!140; Simon McVittie)
9 • The dbus-send(1) man page now documents --bus and --peer instead of
10 the old --address synonym for --peer, which has been deprecated since
11 the introduction of --bus and --peer in 1.7.6
12 (fd.o #48816, dbus!115; Chris Morin)
14 • Fix a wrong environment variable name in dbus-daemon(1)
15 (dbus#275, dbus!122; Mubin, Philip Withnall)
17 • Fix formatting of dbus_message_append_args example
18 (dbus!126, Felipe Franciosi)
20 • When building with CMake, cope with libX11 in a non-standard location
21 (dbus!129, Tuomo Rinne)
23 dbus 1.12.16 (2019-06-11)
24 =========================
26 The “tree cat” release.
30 • CVE-2019-12749: Do not attempt to carry out DBUS_COOKIE_SHA1
31 authentication for identities that differ from the user running the
32 DBusServer. Previously, a local attacker could manipulate symbolic
33 links in their own home directory to bypass authentication and connect
34 to a DBusServer with elevated privileges. The standard system and
35 session dbus-daemons in their default configuration were immune to this
36 attack because they did not allow DBUS_COOKIE_SHA1, but third-party
37 users of DBusServer such as Upstart could be vulnerable.
38 Thanks to Joe Vennix of Apple Information Security.
39 (dbus#269, Simon McVittie)
41 dbus 1.12.14 (2019-05-17)
42 =========================
44 The “reclaimed floorboards” release.
48 • Raise soft fd limit to match hard limit, even if unprivileged.
49 This makes session buses with many clients, or with clients that make
50 heavy use of fd-passing, less likely to suffer from fd exhaustion.
51 (dbus!103, Simon McVittie)
55 • If a privileged dbus-daemon has a hard fd limit greater than 64K, don't
56 reduce it to 64K, ensuring that we can put back the original fd limits
57 when carrying out traditional (non-systemd) activation. This fixes a
58 regression with systemd >= 240 in which system services inherited
59 dbus-daemon's hard and soft limit of 64K fds, instead of the intended
60 soft limit of 1K and hard limit of 512K or 1M.
61 (dbus!103, Debian#928877; Simon McVittie)
63 • Fix build failures caused by an AX_CODE_COVERAGE API change in newer
64 autoconf-archive versions (dbus#249, dbus!88; Simon McVittie)
66 • Fix build failures with newer autoconf-archive versions that include
67 AX_-prefixed shell variable names (dbus#249, dbus!86; Simon McVittie)
69 • Parse section/group names in .service files according to the syntax
70 from the Desktop Entry Specification, rejecting control characters
71 and non-ASCII in section/group names (dbus#208, David King)
73 • Fix various -Wlogical-op issues that cause build failure with newer
74 gcc versions (dbus#225, dbus!109; David King)
76 • Don't assume we can set permissions on a directory, for the benefit of
77 MSYS and Cygwin builds (dbus#216, dbus!110; Simon McVittie)
79 • Don't overwrite PKG_CONFIG_PATH and related environment variables when
80 the pkg-config-based version of DBus1Config is used in a CMake project
81 (dbus#267, dbus!96; Clemens Lang)
83 dbus 1.12.12 (2018-12-04)
84 =========================
86 The “draconic disciple” release.
88 dbus version control is now hosted on freedesktop.org's Gitlab
89 installation, and bug reports and feature requests have switched from
90 Bugzilla bugs (indicated by "fd.o #nnn") to Gitlab issues ("dbus#nnn")
91 and merge requests ("dbus!nnn").
95 • Reference the freedesktop.org Code of Conduct (Simon McVittie)
99 • Stop the dbus-daemon leaking memory (an error message) if delivering
100 the message that triggered auto-activation is forbidden. This is
101 technically a denial of service because the dbus-daemon will
102 run out of memory eventually, but it's a very slow and noisy one,
103 because all the rejected messages are also very likely to have
104 been logged to the system log, and its scope is typically limited by
105 the finite number of activatable services available.
106 (dbus#234, Simon McVittie)
108 • Remove __attribute__((__malloc__)) attribute on dbus_realloc(),
109 which does not meet the criteria for that attribute in gcc 4.7+,
110 potentially leading to miscompilation (fd.o #107741, Simon McVittie)
112 • Fix some small O(1) memory leaks (fd.o #107320, Simon McVittie)
114 • Fix printf formats for pointer-sized integers on 64-bit Windows
115 (fd.o #105662, Ralf Habacker)
117 • Always use select()-based poll() emulation on Darwin-based OSs
118 (macOS, etc.) and on Interix, similar to what libcurl does
119 (dbus#232, dbus!19; Simon McVittie)
121 • Extend a test timeout to avoid spurious failures in CI
122 (dbus!26, Simon McVittie)
126 • Add Travis-CI builds for 64-bit Windows using mingw-w64
127 (fd.o #105662, Ralf Habacker)
129 • Add Gitlab-CI integration (fd.o #108177, Simon McVittie)
131 dbus 1.12.10 (2018-08-02)
132 =========================
134 The “beam deflection” release.
138 • Prevent reading up to 3 bytes beyond the end of a truncated message.
139 This could in principle be an information leak or denial of service
140 on the system bus, but is not believed to be exploitable to crash
141 the system bus or leak interesting information in practice.
142 (fd.o #107332, Simon McVittie)
144 • Fix build with gcc 8 -Werror=cast-function-type
145 (fd.o #107349, Simon McVittie)
147 • Fix warning from gcc 8 about suspicious use of strncpy() when
148 populating struct sockaddr_un (fd.o #107350, Simon McVittie)
150 • Fix a minor memory leak when a DBusServer listens on a new address
151 (fd.o #107194, Simon McVittie)
153 • Fix an invalid NULL argument to rmdir() if a nonce-tcp DBusServer
154 runs out of memory (fd.o #107194, Simon McVittie)
156 • Don't use misleading errno-derived error names if getaddrinfo() or
157 getnameinfo() fails with a code other than EAI_SYSTEM
158 (fd.o #106395, Simon McVittie)
160 • Skip tests that require working TCP if we are in a container environment
161 where 127.0.0.1 cannot be resolved (fd.o #106812, Simon McVittie)
163 dbus 1.12.8 (2018-04-30)
164 ========================
166 The “golden super-velociraptor” release.
170 • The Devhelp documentation index is now in version 2 format
171 (fd.o #106186, Simon McVittie)
173 • Give the dbus-daemon man page some scarier warnings about
174 <allow_anonymous/> and non-local TCP, which are insecure and should
175 not be used, particularly for the standard system and session buses
176 (fd.o #106004, Simon McVittie)
180 • Fix installation of Ducktype documentation with newer yelp-build
181 versions (fd.o #106171, Simon McVittie)
183 dbus 1.12.6 (2018-03-01)
184 ========================
186 The “just the one swan, actually” release.
190 • Increase system dbus-daemon's RLIMIT_NOFILE rlimit before it drops
191 privileges, because it won't have permission afterwards. This fixes a
192 regression in dbus 1.10.18 and 1.11.0 which made the standard system bus
193 more susceptible to deliberate or accidental denial of service.
194 (fd.o #105165, David King)
196 dbus 1.12.4 (2018-02-08)
197 ========================
199 The “Stria Campania 115” release.
203 • When iterating the DBusConnection while blocking on a pending call,
204 don't wait for I/O if that pending call already has a result; and make
205 sure that whether it has a result is propagated in a thread-safe way.
206 This prevents certain multi-threaded calling patterns from blocking
207 until their timeout even when they should have succeeded sooner.
208 (fd.o #102839; Manish Narang, Michael Searle)
210 • Report the correct error if OOM is reached while trying to listen
211 on a TCP socket (fd.o #89104, Simon McVittie)
213 • Fix assertion failures in recovery from OOM while setting up a
214 DBusServer (fd.o #89104, Simon McVittie)
216 • Add a missing space to a warning message (fd.o #103729, Thomas Zajic)
218 • Expand ${bindir} correctly when pkg-config is asked for dbus_daemondir
219 (fd.o #104265, Benedikt Heine)
221 • On Linux systems with systemd < 237, if ${localstatedir}/dbus doesn't
222 exist, create it before trying to create ${localstatedir}/dbus/machine-id
223 (fd.o #104577, Chris Lesiak)
225 • Fix escaping in dbus-api-design document (fd.o #104925, Philip Withnall)
227 dbus 1.12.2 (2017-11-13)
228 ========================
230 The “spider pumpkin” release.
234 • Log a warning if a new connection cannot be accepted due to an
235 out-of-memory condition or failure to identify its AppArmor or
236 SELinux context (fd.o #103592, Simon McVittie)
240 • Make use of $(MKDIR_P) compatible with install-sh, fixing build when a
241 GNU-compatible `mkdir -p` is not available (fd.o #103521, ilovezfs)
243 • When building for Windows with Autotools, avoid `echo -e`, fixing
244 cross-compilation on non-GNU platforms like macOS
245 (fd.o #103493, Tony Theodore)
247 • Fix crashes in the server side of the nonce-tcp: transport under
248 various error conditions. This transport should normally only be used
249 on Windows, where AF_UNIX sockets are unavailable; the unix: transport
250 is the only one recommended for production use on Unix platforms.
251 (fd.o #103597, Simon McVittie)
255 • Improve test coverage on Travis-CI (Simon McVittie)
257 dbus 1.12.0 (2017-10-30)
258 ========================
260 The “gingerbread skull” release.
262 1.12.x is a new stable branch, recommended for use in OS
265 Summary of major changes between 1.10.x and 1.12.0
266 --------------------------------------------------
270 • Expat >= 2.1.0 is required.
271 • GLib >= 2.40 is required if full test coverage is enabled.
272 • [Linux] libselinux >= 2.0.86 is required if SELinux support is
274 • [Unix] dbus now requires an <inttypes.h> that defines C99 constants
275 such as PRId64 and PRIu64, except when building for Windows.
276 • [Autotools] Building from git (but not from tarballs) with Autotools
277 now requires macros from the GNU Autoconf Archive.
278 • [CMake] Builds done using CMake now require CMake 3.0.2.
280 Build-time configuration changes:
282 • Expat is now found using pkg-config. See the release notes for
284 • The --disable-compiler-optimisations and --enable-compiler-coverage
285 options no longer exist. See the release notes for 1.11.4 and 1.11.8.
286 • [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
287 options no longer exist. See the release notes for 1.11.20.
288 • [Unix] Flag files in /var/run/console/${username} are no longer
289 checked for at_console by default. See the release notes for 1.11.18.
290 • [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
291 and packagers will now need to add these downstream (most already do).
292 See the release notes for 1.11.18.
293 • [Unix] The process ID file no longer has a different default location
294 on Red Hat derivatives. See the release notes for 1.11.18.
295 • [Unix] ${runstatedir} is now independent of ${localstatedir} with
296 recent Autotools versions. See the release notes for 1.11.16.
297 • [Windows] The WINDRES variable is no longer used. See the release
302 • Eavesdropping is officially deprecated in favour of BecomeMonitor.
303 See the release notes for spec version 0.31 (in dbus 1.11.14).
304 • [Unix] Flag files in /var/run/console/${username} are deprecated.
305 See the release notes for 1.11.18.
309 • <allow> and <deny> rules in dbus-daemon configuration can now
310 include send_broadcast="true", send_broadcast="false",
311 max_unix_fds="N", min_unix_fds="N" (for some integer N).
312 See the release notes for 1.11.18.
313 • dbus_try_get_local_machine_id() is like
314 dbus_get_local_machine_id(), but returns a DBusError.
315 • New APIs around DBusMessageIter to simplify cleanup.
316 See the release notes for 1.11.16.
317 • The message bus daemon now implements the standard Introspectable,
318 Peer and Properties interfaces. See the release notes for
319 dbus 1.11.14 and spec version 0.31.
320 • DTDs for introspection XML and bus configuration are installed.
321 • dbus can be compiled to be relocatable, making it more suitable for
322 binary bundling with other software. On Windows, this is on by
324 • [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
325 never uses Linux abstract sockets, which is advantageous for
326 containers. On non-Linux it is equivalent to unix:tmpdir=….
327 See the release notes for dbus 1.11.14 and spec version 0.31.
328 • [Unix] New option "dbus-launch --exit-with-x11".
329 • [Unix] Session managers can create transient .service files in
330 $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
331 • [Unix] A sysusers.d snippet can create the messagebus user on-demand.
333 Miscellaneous behaviour changes:
335 • [Unix] The session bus now logs to syslog if it was started by
337 • [Unix] Internal warnings are logged to syslog if configured.
338 • [Unix] Exceeding an anti-DoS limit is logged to syslog if configured,
341 Changes since 1.11.22 release candidate
342 ---------------------------------------
344 Standard stable-branch changes:
346 • Disable warnings about use of deprecated functions (Simon McVittie)
350 • Don't distribute files generated by ./configure in the source tarball
351 (fd.o #103420, Simon McVittie)
355 • Remove some unused files from the git repository
356 (fd.o #103420, Simon McVittie)
358 D-Bus 1.11.22 (2017-10-23)
359 ==========================
361 The “fire surface” release.
363 This is the first release-candidate for the 1.12.0 stable release.
365 Build-time configuration changes:
367 • When building for Windows with Autotools, setting the WINDRES variable
368 no longer works to select a non-standard resource compiler. Use
369 libtool's standard RC variable instead, for example
370 "./configure RC=i686-w64-mingw32-windres"
374 • Builds done using CMake now require CMake 3.0.2.
378 • When building for Windows, improve quality of metadata in
379 libdbus-1-3.dll (fd.o #103015, Ralf Habacker)
383 • Fix a typo "uint 16" in dbus-send(1) man page
384 (fd.o #103075, David King)
386 • When building for Windows, libdbus-1-3.dll always includes version
387 information. Previously, this was missing if using CMake and any
388 non-MSVC compiler. (fd.o #103015, Ralf Habacker)
390 • Fix the build with MSVC, which regressed with the #102558 fix in
391 1.11.20. (fd.o #102558, Ralf Habacker)
395 • Simplify Windows resource embedding
396 (fd.o #103015, Simon McVittie)
398 D-Bus 1.11.20 (2017-10-03)
401 The “wraith stun” release.
403 Build-time configuration changes:
405 • The --enable-abstract-sockets and --disable-abstract-sockets options
406 no longer exist. Support for Linux's abstract AF_UNIX sockets is now
407 unconditionally enabled on Linux and disabled everywhere else.
408 (fd.o #34905, Simon McVittie)
412 • Make slower tests less likely to time out, and improve diagnostics if
413 tests do time out (fd.o #103009, Simon McVittie)
415 • On Windows, don't compile an unused stub implementation of
416 _dbus_set_signal_handler() (fd.o #103010, Simon McVittie)
420 • Be more careful to save and restore errno in POSIX async signal
421 handlers (fd.o #103010, Simon McVittie)
423 • On Windows, embed a manifest in dbus-update-activation-environment.exe
424 so that the heuristics used for UAC do not assume it needs elevated
425 privileges due to its name containing "update"
426 (fd.o #102558, Ralf Habacker)
428 • On Windows with Automake, embed version information in libdbus-1,
429 as was meant to happen in all versions since 2009
430 (fd.o #103015, Simon McVittie)
432 D-Bus 1.11.18 (2017-09-25)
435 The “vampire conquistador” release.
437 Build-time configuration changes:
439 • By default, dbus-daemon on Unix no longer checks for flag files
440 /var/run/console/${username} created by the obsolete pam_console and
441 pam_foreground PAM modules when deciding whether ${username} is
442 currently at the console. The old default behaviour can be restored
443 by specifying --with-console-auth-dir=/var/run/console in the
444 recommended Autotools build system, or
445 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
446 now deprecated, and will be removed in dbus 1.13 unless feedback via
447 fd.o #101629 indicates that this would be problematic.
448 (fd.o #101629, Simon McVittie)
450 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
451 script for Cygwin, are no longer provided in the upstream dbus
452 source. We recommend that distributors who support non-systemd service
453 management should maintain their own init scripts or other service
454 manager integration as part of their downstream packaging, similar to
455 the way Debian distributes a Debian-specific LSB init script for dbus.
457 The systemd unit continues to be maintained as part of the upstream
458 dbus source, because it receives regular testing and maintenance.
460 (fd.o #101706, Simon McVittie)
462 • The process ID file created by the system bus is no longer influenced
463 by the --with-init-scripts=redhat configure option or the presence of
464 /etc/redhat-release at build time. If your OS's init script or other
465 service management relies on the Red Hat-style pid file, it can be
466 restored by specifying --with-system-pid-file=/run/messagebus.pid at
467 configure time or using the <pidfile> directive in bus configuration.
469 Note that the upstream-supplied systemd unit runs dbus-daemon with
470 the --nopidfile option, so it does not normally write a pid file,
471 regardless of whether the OS is Red-Hat-derived or not.
473 (fd.o #101706, Simon McVittie)
477 • <allow> and <deny> rules in dbus-daemon configuration can now
478 include send_broadcast="true" or send_broadcast="false", which make
479 the rule only match broadcast signals, or only match messages that
480 are not broadcast signals, respectively.
481 (fd.o #29853, Simon McVittie)
483 • <allow> and <deny> rules can now be configured to apply only to
484 messages with or without Unix file descriptors attached. This would
485 typically be used in rules like these:
486 <allow send_destination="..." max_unix_fds="0"/>
487 <deny send_destination="..." min_unix_fds="1"/>
488 <deny receive_sender="..." min_unix_fds="1"/>
489 but can also be used to set a nonzero upper limit on the number of
491 <allow send_destination="..." max_unix_fds="4"/>
492 (fd.o #101848, Simon McVittie)
494 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
495 now respects the HOME environment variable on the client side, and
496 on the server side when the uid attempting to connect is the same
497 as the uid of the server. This allows the automated tests to pass in
498 environments where the user's "official" home directory in /etc/passwd
499 is nonexistent, such as Debian autobuilders.
500 (fd.o #101960, Simon McVittie)
504 • When parsing dbus-daemon configuration, tell Expat not to use
505 cryptographic-quality entropy as a salt for its hash tables: we trust
506 the configuration files, so we are not concerned about algorithmic
507 complexity attacks via hash table collisions. This prevents
508 dbus-daemon --system from holding up the boot process (and causing
509 early-boot system services like systemd, logind, networkd to time
510 out) on entropy-starved embedded systems.
511 (fd.o #101858, Simon McVittie)
513 • Avoid a -Werror=declaration-after-statement build failure on Solaris
514 (fd.o #102145, Alan Coopersmith)
516 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
517 to LOG_INFO, matching how we use this log level in practice
518 (fd.o #102686, Simon McVittie)
520 D-Bus 1.11.16 (2017-07-27)
523 The “south facing garden” release.
525 Build-time configuration changes:
527 • The Autotools build system now supports varying ${runstatedir}
528 independently of ${localstatedir}, if using an Autoconf version
529 that has that feature; version 2.70 will eventually have this, but
530 many Linux distributions add it to version 2.69 as a patch.
531 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
532 and runstatedir=/run. (fd.o #101569, Simon McVittie)
536 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
537 and dbus_message_iter_abandon_container_if_open() simplify the
538 single-exit-point ("goto out") style of resource cleanup. The API
539 documentation around DBusMessageIter and containers has also been
540 clarified. (fd.o #101568, Simon McVittie)
544 • Fix the implementation of re-enabling a timeout (again) so that its
545 countdown is always restarted as intended. (fd.o #95619,
548 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
549 available to all users on the system bus (fd.o #101700, Simon McVittie)
551 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
552 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
554 • dbus_message_iter_open_container() no longer leaks memory if it runs out
555 of memory. (fd.o #101568, Simon McVittie)
557 • dbus_message_append_args_valist() no longer leaks memory if given an
558 unsupported type. This situation is still considered to be a programming
559 error which needs to be corrected by the user of libdbus.
560 (fd.o #101568, Simon McVittie)
562 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
563 will no longer report that their arguments were invalid if they run out
564 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
566 • Ensure that tests fail if they would otherwise have tried to connect to
567 the real session bus (fd.o #101698, Simon McVittie)
569 • Make build-time tests cope with finding Python 3, but not Python 2
570 (fd.o #101716, Simon McVittie)
572 Internal changes relevant to dbus developers:
574 • DBusVariant is a new mechanism to copy single values from a message into
575 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
577 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
578 Logging an ERROR message does not make the process exit; the caller
579 is responsible for calling abort() or exit(), whichever is more appropriate.
580 (fd.o #101568, Simon McVittie)
582 • Better test coverage (fd.o #101568, Simon McVittie)
584 D-Bus 1.11.14 (2017-06-29)
587 The “irrational fear of bees” release.
591 • Expat >= 2.1.0 is always required
592 • libselinux >= 2.0.86 is required if SELinux support is enabled
593 • GLib >= 2.40 is required if full test coverage is enabled
595 Build-time configuration changes:
597 • We now use pkg-config to find libexpat in Autotools builds. This requires
598 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
599 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
600 itself cause compilation failures.
602 As with all pkg-config-based configure checks, you can use
603 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
604 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
605 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
608 (fd.o #69801, Simon McVittie)
610 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
611 is required due to the removal of explicit refcounting for SIDs.
612 (fd.o #100912, Laurent Bigonville)
616 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
617 as a side-effect of a sufficiently privileged process merely reading the
618 machine ID. It is no longer copied as a side-effect of reading.
619 Running dbus-uuidgen --ensure, which should be done after installing dbus,
620 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
621 former exists and the latter does not.
622 (fd.o #101257, Simon McVittie)
624 • The undocumented Verbose interface, and the GetAllMatchRules method on
625 the undocumented Stats interface, must now be used via the object path
626 /org/freedesktop/DBus. Previously, they existed on all object paths.
627 (fd.o #101257, Simon McVittie)
629 • AddMatch() with a match rule containing eavesdrop='true' will now fail
630 unless called by either the same user as the dbus-daemon, or Unix uid 0
631 (root), matching the restrictions applied to the newer BecomeMonitor()
632 method. On the session bus this has no practical effect. On the system
633 bus this will prevent certain configurations that already did not
634 work well in practice. (fd.o #101567, Simon McVittie)
638 • D-Bus Specification version 0.31
639 · Don't require implementation-specific search paths to be lowest
641 · Correct regex syntax for optionally-escaped bytes in addresses so it
642 includes hyphen-minus, forward slash and underscore as intended
643 · Describe all message bus methods in the same section
644 · Clarify the correct object path for method calls to the message bus
645 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
646 · Document that the message bus implements Introspectable, Peer and
648 · Add new Features and Interfaces properties for message bus
650 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
652 · Don't require eavesdrop='true' to be accepted from connections not
653 sufficiently privileged to use it successfully
654 · Formally deprecate eavesdropping in favour of BecomeMonitor
655 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
656 Simon McVittie, Tom Gundersen)
658 • Implement the Properties and Peer interfaces in dbus-daemon
659 (fd.o #101257, Simon McVittie)
661 • New function dbus_try_get_local_machine_id() is like
662 dbus_get_local_machine_id(), but returning a DBusError. Other code
663 that needs the machine ID will now report a recoverable error (instead
664 of logging to stderr and aborting) if no machine ID is available.
665 Generating a machine ID is still considered to be a required part of
666 installing dbus correctly. (fd.o #13194, Simon McVittie)
668 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
669 (fd.o #101315, Laurent Bigonville)
671 • Avoid deprecated API calls when using SELinux
672 (fd.o #100912, Laurent Bigonville)
674 • Switch a test from the deprecated g_test_trap_fork() to
675 g_test_trap_subprocess(), for Windows support and better robustness
676 on Unix (fd.o #101362, Simon McVittie)
678 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
679 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
680 This prevents the two files from going out of sync on stateless or live
681 images without needing to run dbus-uuidgen, and supports older D-Bus
682 implementations that do not necessarily read /etc/machine-id themselves.
683 (fd.o #101570, Simon McVittie)
685 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
686 abstract sockets. This is preferable when used with Linux containers.
687 (fd.o #101567, Simon McVittie)
691 • Fix a reference leak when blocking on a pending call on a connection
692 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
694 • Don't put timestamps in the Doxygen-generated documentation,
695 or hard-code the build directory into builds with embedded tests,
696 for reproducible builds (fd.o #100692, Simon McVittie)
698 • Fix some integration test issues (fd.o #100686, Simon McVittie)
700 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
702 • If we somehow get an autolaunch address with multiple semicolon-separated
703 components, and they don't work, don't invalidly "pile up" errors
704 (fd.o #101257, Simon McVittie)
708 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
709 (fd.o #100715, Simon McVittie)
711 D-Bus 1.11.12 (2017-04-07)
714 The “it's something humans do” release.
718 • The session dbus-daemon now supports transient .service files
719 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
720 service directories, this directory is not monitored with inotify
721 or similar, and the service files must be named exactly
722 ${bus_name}.service. (fd.o #99825, Simon McVittie)
724 • dbus can be configured with --enable-relocation when building with
725 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
726 to make the pkg-config metadata relocatable. This is useful for
727 non-standard prefixes, and in particular for Windows installations.
728 However, it is not recommended for system-wide installations into
729 /usr, because it interferes with pkg-config's ability to filter out
730 compiler default linker directories.
732 With Autotools, the default is --enable-relocation when building
733 for Windows or --disable-relocation otherwise. With CMake, the default
734 is -DDBUS_RELOCATABLE=ON.
736 (fd.o #99721; Ralf Habacker, Simon McVittie)
738 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
739 own FindDBus.cmake macros, whether dbus was compiled with Autotools
740 or with CMake. See the end of README.cmake for more information.
741 (fd.o #99721; Ralf Habacker, Simon McVittie)
745 • Always read service file directories in the intended order
746 (fd.o #99825, Simon McVittie)
748 • When tests are skipped, don't try to kill nonexistent process 0
749 (fd.o #99825, Simon McVittie)
751 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
753 • Fix a harmless read overflow and some memory leaks in a unit test
754 (fd.o #100568, Philip Withnall)
756 • Fix some typos in test code
757 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
759 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
760 in documentation (fd.o #99901, Philip Withnall)
762 • Fix and enable compiler warnings related to -Wswitch
763 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
765 • Fix writing off the end of a fd_set when testing with valgrind
766 (fd.o #99839, Philip Withnall)
768 D-Bus 1.11.10 (2017-02-16)
771 The “purple hair gives you telekinesis?” release.
775 • AppArmor support requires at least libapparmor 2.8.95, reduced
776 from 2.10 in previous versions. One test requires 2.10 and is
777 skipped if building with an older version.
781 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
782 stable and Debian testing in addition to the older Ubuntu that is
783 the default (fd.o #98889, Simon McVittie)
785 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
787 • Silence many -Wswitch-enum and -Wswitch-default warnings
788 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
790 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
791 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
793 • Install pkg-config metadata on Unix even if building with CMake
794 (fd.o #99752, Ralf Habacker)
796 • Exclude auth mechanisms from REJECTED message if they are supported
797 in the code but but configured to be disallowed (fd.o #99621,
802 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
803 allow an attacker to overwrite a file named "nonce", in a directory
804 that the user running dbus-daemon can write, with a random value
805 known only to the user running dbus-daemon. This is unlikely to be
806 exploitable in practice, particularly since the nonce-tcp transport
807 is really only useful on Windows.
809 On Unix systems we strongly recommend using only the unix: and systemd:
810 transports, together with EXTERNAL authentication. These are the only
811 transports and authentication mechanisms enabled by default.
813 (fd.o #99828, Simon McVittie)
815 • Avoid symlink attacks in the "embedded tests", which are not enabled
816 by default and should never be enabled in production builds of dbus.
817 (fd.o #99828, Simon McVittie)
819 • Fix the implementation of re-enabling a timeout so that its
820 countdown is restarted as intended, instead of continually
821 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
823 • When receiving a message with file descriptors, do not start reading
824 the beginning of the next message, so that only one such message
825 is processed at a time. In conjunction with the fix for #95619
826 this means that processes sending many file descriptors, such as
827 systemd-logind on a system that receives very rapid ssh connections,
828 are not treated as abusive and kicked off the bus. Revert the previous
829 workaround that special-cased uid 0.
830 (fd.o #95263, LP#1591411; Simon McVittie)
832 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
833 for Windows with CMake (fd.o #99586, Ralf Habacker)
835 • Do not set Unix-specific variables when targeting Windows
836 (fd.o #99586, Ralf Habacker)
838 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
839 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
841 • Use relative install locations in CMake on Unix to respect DESTDIR,
842 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
844 • Install dbus-arch-deps.h correctly when using CMake
845 (fd.o #99586, #99721; Ralf Habacker)
847 • Improve argument validation for `dbus-test-tool spam`
848 (ffd.o #99693, Coverity #54759; Philip Withnall)
850 • Don't shift by a negative integer if a hash table becomes monstrously
851 large (fd.o #99641, Coverity #54682; Philip Withnall)
853 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
854 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
856 • Remove an unnecessary NULL check
857 (fd.o #99642, Coverity #141062; Philip Withnall)
859 • Improve error handling in unit tests and dbus-send
860 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
861 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,
862 #54710, #54711, #54714, #54715, #54718, #54721, #54724, #54726,
863 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
865 • Do not print verbose messages' timestamps to stderr if the actual message
866 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
868 D-Bus 1.11.8 (2016-11-28)
871 The “panics in the face of breakfast foods” release.
873 Build-time configuration:
875 • The new --enable-debug configure option provides an easy way to
876 enable debug symbols, disable optimization and/or enable profiling.
878 • The --enable-compile-warnings configure option can be used to control
881 • The --disable-compiler-optimisations configure option is no longer
882 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
886 • D-Bus Specification version 0.30
887 · Define the jargon term "activation" more clearly
888 · Define the jargon term "auto-starting", which is one form of activation
889 · Document the optional SystemdService key in service files
890 · Use versioned interface and bus names in most examples
891 · Clarify intended behaviour of Properties.GetAll
892 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
894 • Fix and enable a lot of compiler warnings to improve future code
895 quality. This might incidentally also fix some environment variable
897 · In particular, printf-style functions in the libdbus API are now annotated
898 with __attribute__((__format__(__printf__, *, *))) when compiling with
899 gcc or clang. This might make printf bugs in other software visible
901 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
902 Thomas Zimmermann, Simon McVittie)
904 • When running with AppArmor mediation (for example using Ubuntu's patched
905 Linux kernel), clients can no longer auto-start services unless they would
906 have been able to send the auto-starting message to the service after it
907 starts. StartServiceByName() is unaffected, and continues to be allowed by
908 default in AppArmor's <abstractions/dbus-strict> and
909 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
913 • Work around an undesired effect of the fix for CVE-2014-3637
914 (fd.o #80559), in which processes that frequently send fds, such as
915 logind during a flood of new PAM sessions, can get disconnected for
916 continuously having at least one fd "in flight" for too long;
917 dbus-daemon interprets that as a potential denial of service attack.
918 The workaround is to disable that check for uid 0 process such as
919 logind, with a message in the system log. The bug remains open while
920 we look for a more general solution.
921 (fd.o #95263, LP#1591411; Simon McVittie)
923 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
924 was disabled at compile time. That test is not expected to work
925 in that configuration. (fd.o #98665, Simon McVittie)
927 D-Bus 1.11.6 (2016-10-10)
930 The “darkly whimsical” release.
934 • Do not treat ActivationFailure message received from root-owned systemd
935 name as a format string. In principle this is a security vulnerability,
936 but we do not believe it is exploitable in practice, because only
937 privileged processes can own the org.freedesktop.systemd1 bus name, and
938 systemd does not appear to send activation failures that contain "%".
940 Please note that this probably *was* exploitable in dbus versions
941 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
942 the time was only thought to be a denial of service vulnerability
943 (CVE-2015-0245). If you are still running one of those versions,
944 patch or upgrade immediately.
946 (fd.o #98157, Simon McVittie)
950 • D-Bus Specification version 0.29
951 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
952 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
954 • Log to syslog when we exceed various anti-DoS limits, and add test
955 coverage for them (fd.o #86442, Simon McVittie)
957 • Improve syslog handling so that _dbus_warn() and similar warnings
958 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
959 and log to syslog (instead of /dev/null) when dbus-daemon is started by
960 dbus-launch. (fd.o #97009, Simon McVittie)
962 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
963 (fd.o #89011, Philip Withnall)
965 • When logging messages about service activation, mention which peer
966 requested the activation (fd.o #68212, Philip Withnall)
968 • On Linux, mention the LSM label (if available) whenever we print
969 debug information about a peer (fd.o #68212, Philip Withnall)
973 • Harden dbus-daemon against malicious or incorrect ActivationFailure
974 messages by rejecting them if they do not come from a privileged
975 process, or if systemd activation is not enabled
976 (fd.o #98157, Simon McVittie)
978 • Avoid undefined behaviour when setting reply serial number without going
979 via union DBusBasicValue (fd.o #98035, Marc Mutz)
981 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
982 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
984 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
986 D-Bus 1.11.4 (2016-08-15)
989 The “copper pickaxe” release.
993 • Building from git (but not from tarballs) now requires
994 macros from the GNU Autoconf Archive, for example the autoconf-archive
995 package in Debian or Fedora derivatives.
997 Build-time configuration:
999 • The option to enable coverage instrumentation has changed from
1000 --enable-compiler-coverage to --enable-code-coverage.
1004 • D-Bus Specification version 0.28
1005 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
1007 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
1008 minimizing failed connections under heavy load
1009 (fd.o #95264, Lennart Poettering)
1011 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
1013 • Use the same regression tests for subprocess starting on Unix and Windows
1014 (fd.o #95191, Ralf Habacker)
1016 • Print timestamps and thread IDs in verbose messages
1017 (fd.o #95191, Ralf Habacker)
1019 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
1020 pointing to /dev/null (fd.o #97008, Simon McVittie)
1022 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
1023 (fd.o #88922, Thomas Zimmermann)
1027 • On Windows, fix a memory leak in replacing the installation prefix
1028 (fd.o #95191, Ralf Habacker)
1030 • On Linux, when dbus-daemon is run with reduced susceptibility to the
1031 OOM killer (typically via systemd), do not let child processes inherit
1032 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
1034 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
1035 even if a parent process incorrectly starts them with stdin, stdout
1036 and/or stderr closed (fd.o #97008, Simon McVittie)
1038 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
1039 contains a semicolon (fd.o #94746, Thiago Macieira)
1041 • Fix memory leaks and thread safety in subprocess starting on Windows
1042 (fd.o #95191, Ralf Habacker)
1044 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
1045 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
1047 • In tests that exercise correct handling of crashing D-Bus services,
1048 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
1050 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
1052 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
1053 in some test cases (fd.o #93909, Nick Lewycky)
1055 • Add assertions to reassure a static analysis tool
1056 (fd.o #93210, Deepika Aggarwal)
1058 • Be explicit about enum comparison when loading XML
1059 (fd.o #93205, Deepika Aggarwal)
1061 • update-activation-environment: produce better diagnostics on error
1062 (fd.o #96653, Simon McVittie)
1064 • Avoid various compiler warnings with gcc 6
1065 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
1067 • On Unix when configured to use the system log, report as "dbus-daemon",
1068 not as "dbus" (fd.o #97009, Simon McVittie)
1070 • During unit tests, reduce the amount we write to the system log
1071 (fd.o #97009, Simon McVittie)
1073 D-Bus 1.11.2 (2016-03-07)
1076 The “pneumatic drill vs. Iron Maiden” release.
1080 • Enable "large file support" on systems where it exists: dbus-daemon
1081 is not expected to open large files, but it might need to stat files
1082 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
1084 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
1085 which might result in a pedantic C compiler not copying the entire contents
1086 of a DBusMessageIter; statically assert that this is not an ABI change
1087 in practice (fd.o #94136, Simon McVittie)
1089 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
1090 (fd.o #94244, Dmitri Iouchtchenko)
1092 • Correctly report test failures in C tests from run-test.sh
1093 (fd.o #93379; amit tewari, Simon McVittie)
1095 • When tests are enabled, run all the marshal-validate tests, not just
1096 the even-numbered ones (fd.o #93908, Nick Lewycky)
1098 • Correct the expected error from one marshal-validate test, which was
1099 previously not run due to the above bug (fd.o #93908, Simon McVittie)
1101 • Fix compilation under CMake when embedded tests are disabled
1102 (fd.o #94094, eric.hyer)
1106 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
1107 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
1109 • When building with CMake, use the same gcc/clang warnings as under Autotools,
1110 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
1112 • test/name-test: make C tests produce TAP output and run them directly, not
1113 via run-test.sh (fd.o #92899, Simon McVittie)
1115 • Under CMake when cross-compiling for Windows on Unix, run the tests
1116 under Wine even if binfmt_misc support is not available
1117 (fd.o #88966, Ralf Habacker)
1119 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
1120 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
1122 • Factor out some functions that will be needed in future for a Windows
1123 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
1125 D-Bus 1.11.0 (2015-12-02)
1128 The “peppermint deer” release.
1132 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
1133 C99 constants such as PRId64 and PRIu64.
1137 • D-Bus Specification version 0.27
1138 · Specify that services should not reply if NO_REPLY_EXPECTED was used
1139 (fd.o #75749, Lars Uebernickel)
1141 • Add a script to do continuous-integration builds, and metadata to run it
1142 on travis-ci.org. To use this, clone the dbus git repository on GitHub
1143 and set it up with travis-ci.org; the only special setting needed is
1144 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
1146 • If dbus-daemon is run with --systemd-activation, do not require
1147 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
1151 • Re-order dbus-daemon startup so that on SELinux systems, the thread
1152 that reads AVC notifications retains the ability to write to the
1153 audit log (fd.o #92832, Laurent Bigonville)
1155 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
1157 • When using the Monitoring interface, match messages' destinations
1158 (fd.o #92074, Simon McVittie)
1160 • On Linux with systemd, stop installing a reference to the obsolete
1161 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
1164 • On Windows, when including configuration files with <include> or
1165 <includedir>, apply the same relocation as for the Exec paths
1166 in .service files (fd.o #92028, Simon McVittie)
1168 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
1170 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
1172 D-Bus 1.10.6 (2015-12-01)
1175 The “marzipan beetles” release.
1179 • On Unix when running tests as root, don't assert that root and
1180 the dbus-daemon user can still call UpdateActivationEnvironment;
1181 assert that those privileged users can call BecomeMonitor instead
1182 (fd.o #93036, Simon McVittie)
1184 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
1187 • On Windows Autotools builds, don't run tests that rely on
1188 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
1190 D-Bus 1.10.4 (2015-11-17)
1193 The “Frostburn Canyon” release.
1197 • GetConnectionCredentials, GetConnectionUnixUser and
1198 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
1199 will now return details of the dbus-daemon itself. This is required
1200 to be able to call SetEnvironment on systemd.
1201 (fd.o #92857, Jan Alexander Steffens)
1205 • Make UpdateActivationEnvironment always fail with AccessDenied on the
1206 system bus. Previously, it was possible to configure it so root could
1207 call it, but the environment variables were not actually used,
1208 because the launch helper would discard them.
1209 (fd.o #92857, Jan Alexander Steffens)
1211 • On Unix with --systemd-activation on a user bus, make
1212 UpdateActivationEnvironment pass on its arguments to systemd's
1213 SetEnvironment method, solving inconsistency between the environments
1214 used for traditional activation and systemd user-service activation.
1215 (fd.o #92857, Jan Alexander Steffens)
1217 • On Windows, don't crash if <syslog/> or --syslog is used
1218 (fd.o #92538, Ralf Habacker)
1220 • On Windows, fix a memory leak when setting a DBusError from a Windows
1221 error (fd.o #92721, Ralf Habacker)
1223 • On Windows, don't go into infinite recursion if we abort the process
1224 with backtraces enabled (fd.o #92721, Ralf Habacker)
1226 • Fix various failing tests, variously on Windows and cross-platform:
1227 · don't test system.conf features (users, groups) that only make sense
1228 on the system bus, which is not supported on Windows
1229 · don't call _dbus_warn() when we skip a test, since it is fatal
1230 · fix computation of expected <standard_session_servicedirs/>
1231 · when running TAP tests, translate newlines to Unix format, fixing
1232 cross-compiled tests under Wine on Linux
1233 · don't stress-test refcounting under Wine, where it's really slow
1234 · stop assuming that a message looped-back to the test will be received
1236 · skip some system bus tests on Windows since they make no sense there
1237 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
1239 D-Bus 1.10.2 (2015-10-26)
1242 The “worst pies in London” release.
1246 • Correct error handling for activation: if there are multiple attempts
1247 to activate the same service and it fails immediately, the first attempt
1248 would get the correct reply, but the rest would time out. We now send
1249 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
1251 • If BecomeMonitor is called with a syntactically invalid match rule,
1252 don't crash with an assertion failure, fixing a regression in 1.9.10.
1253 This was not exploitable as a denial of service, because the check
1254 for a privileged user is done first. (fd.o #92298, Simon McVittie)
1256 • On Linux with --enable-user-session, add the bus address to the
1257 environment of systemd services for better backwards compatibility
1258 (fd.o #92612, Jan Alexander Steffens)
1260 • On Windows, fix the logic for replacing the installation prefix
1261 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
1263 • On Windows, if installed in the conventional layout with ${prefix}/etc
1264 and ${prefix}/share, use relative paths between bus configuration files
1265 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
1267 • Make more of the regression tests pass in Windows builds (fd.o #92538,
1270 D-Bus 1.10.0 (2015-08-25)
1275 This is a new stable branch, recommended for use in OS distributions.
1279 • distribute test/tap-test.sh.in, even if the tarball was built without
1280 tests enabled (fd.o #91684, Simon McVittie)
1281 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
1283 Summary of major changes since 1.8.0:
1285 • The basic setup for the well-known system and session buses is
1286 now done in read-only files in ${datadir} (normally /usr/share).
1287 See the NEWS entry for 1.9.18 for details.
1289 • AppArmor integration has been merged, with features similar to the
1290 pre-existing SELinux integration. It is mostly compatible with the
1291 patches previously shipped by Ubuntu, with one significant change:
1292 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
1293 by GetConnectionCredentials and was not included.
1295 • The --enable-user-session configure option can be enabled
1296 by OS integrators intending to use systemd to provide a session bus
1297 per user (in effect, treating all concurrent graphical and non-graphical
1298 login sessions as one large session).
1300 • The new listenable address mode "unix:runtime=yes" listens on
1301 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
1302 user session. libdbus and "dbus-launch --autolaunch" will connect to
1303 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
1306 • All executables are now dynamically linked to libdbus-1.
1307 Previously, some executables, most notably dbus-daemon, were statically
1308 linked to a specially-compiled variant of libdbus. This results in
1309 various private functions in the _dbus namespace being exposed by the
1310 shared library. These are not API, and must not be used outside
1311 the dbus source tree.
1313 • On platforms with ELF symbol versioning, all public symbols
1314 are versioned LIBDBUS_1_3.
1318 • org.freedesktop.DBus.GetConnectionCredentials returns
1319 LinuxSecurityLabel where supported
1320 • org.freedesktop.DBus.Monitoring interface (privileged)
1321 · BecomeMonitor method supersedes match rules with eavesdrop=true,
1322 which are now deprecated
1323 • org.freedesktop.DBus.Stats interface (semi-privileged)
1324 · now enabled by default
1325 · new GetAllMatchRules method
1326 • org.freedesktop.DBus.Verbose interface (not normally compiled)
1327 · toggles the effect of DBUS_VERBOSE
1332 • dbus-update-activation-environment
1334 New optional dependencies:
1336 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
1337 • Complete documentation requires Ducktype and yelp-tools
1338 • Full test coverage requires GLib 2.36 and PyGI
1339 • AppArmor integration requires libapparmor and optionally libaudit
1341 Dependencies removed:
1345 D-Bus 1.9.20 (2015-08-06)
1348 The “Remember Tomorrow” release.
1350 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
1355 • Don't second-guess what the ABI of poll() is, allowing it to be used
1356 on Integrity RTOS and other unusual platforms (fd.o #90314;
1357 Rolland Dudemaine, Simon McVittie)
1359 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
1360 both enabled (fd.o #89225, Simon McVittie)
1362 • Log audit events for AppArmor/SELinux policy violations whenever
1363 we have CAP_AUDIT_WRITE, even if not the system bus
1364 (fd.o #83856, Laurent Bigonville)
1366 D-Bus 1.9.18 (2015-07-21)
1369 The “Pirate Elite” release.
1371 Configuration changes:
1373 • The basic setup for the well-known system and session buses is now done
1374 in read-only files in ${datadir}, moving a step closer to systems
1375 that can operate with an empty /etc directory. In increasing order
1378 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
1379 the default message policies.
1380 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
1381 dbus still installs a trivial version of each, for documentation
1382 purposes; putting configuration directives in these files is deprecated.
1383 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
1384 to install "drop-in" configuration snippets (any packages
1385 using those directories should explicitly depend on at least this
1387 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
1388 or third-party software to install "drop-in" configuration snippets
1389 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
1392 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
1393 and "s*" refers to either system or session as appropriate.
1395 (fd.o #89280, Dimitri John Ledkov)
1399 • Fix a memory leak when GetConnectionCredentials() succeeds
1400 (fd.o #91008, Jacek Bukarewicz)
1402 • Ensure that dbus-monitor does not reply to messages intended for others,
1403 resulting in its own disconnection (fd.o #90952, Simon McVittie)
1405 D-Bus 1.9.16 (2015-05-14)
1408 The “titanium barns” release.
1412 • Automake 1.13 is now required when compiling from git or modifying
1417 • On Unix platforms, change the default configuration for the session bus
1418 to only allow EXTERNAL authentication (secure kernel-mediated
1419 credentials-passing), as was already done for the system bus.
1421 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
1422 unpredictable pseudo-random numbers.
1424 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
1425 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1426 NFS or similar, you will need to reconfigure the session bus to accept
1427 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1430 (fd.o #90414, Simon McVittie)
1432 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1433 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1434 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1435 occurs, instead of silently falling back to low-entropy pseudorandom
1436 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1440 • Add dbus_message_iter_get_element_count()
1441 (fd.o #30350; Christian Dywan, Simon McVittie)
1443 • Introduce new internal DBusSocket and DBusPollable types so we can
1444 stop treating the Windows SOCKET type as if it was int. DBusSocket
1445 is specifically a socket, cross-platform. DBusPollable is whatever
1446 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1447 (fd.o #89444; Ralf Habacker, Simon McVittie)
1449 • All regression tests now output TAP <https://testanything.org/>
1450 (fd.o #89846, Simon McVittie)
1452 • Internal APIs consistently use signed values for timestamps
1453 (fd.o #18494, Peter McCurdy)
1455 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1456 (fd.o #88812, Simon McVittie)
1458 • Clean up a lot of compiler warnings
1459 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1463 • Add locking to DBusCounter's reference count and notify function
1464 (fd.o #89297, Adrian Szyndela)
1466 • Ensure that DBusTransport's reference count is protected by the
1467 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1469 • Correctly release DBusServer mutex before early-return if we run out
1470 of memory while copying authentication mechanisms (fd.o #90021,
1473 • Make dbus-test-tool and dbus-update-activation-environment portable
1474 to Windows (fd.o #90089, Ralf Habacker)
1476 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1477 Ralf Habacker, Simon McVittie)
1479 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1482 • Clean up some memory and fd leaks in test code and tools
1483 (fd.o #90021, Ralf Habacker)
1485 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1486 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1488 • CMake generates a versioned shared library even if the revision is 0,
1489 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1491 D-Bus 1.9.14 (2015-03-02)
1494 The “don't stand in the poison cloud” release.
1498 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1499 were previously linked to a static version of libdbus.
1501 • The tests no longer require dbus-glib in order to exercise the libdbus
1502 shared library; they are always linked to libdbus now.
1504 Build-time configuration:
1506 • The new --enable-user-session option, off by default, can be enabled
1507 by OS integrators intending to use systemd to provide a session bus
1508 per user (in effect, treating all concurrent graphical and non-graphical
1509 login sessions as one large session)
1513 • All executables are now linked dynamically to libdbus.
1514 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1516 • On platforms that support them (GNU libc and possibly others),
1517 libdbus now has versioned symbols for its public API.
1518 All public symbols (visible in the header files) are currently
1519 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1520 dbus_internal have a version that changes with each release, and
1521 must not be used by applications. (also fd.o #83115)
1523 • New listenable address mode "unix:runtime=yes" which listens on
1524 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1525 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1527 • Add optional systemd units for a per-user bus listening on
1528 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1530 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1531 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1534 • New dbus-update-activation-environment tool uploads environment
1535 variables to "dbus-daemon --session" and optionally "systemd --user",
1536 primarily as a way to keep the per-user bus compatible with
1537 distributions' existing X11 login scripts (also fd.o #61301)
1539 • <includedir/> elements in dbus-daemon configuration are now silently
1540 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1542 • Add microsecond-resolution timestamps to the default output of
1543 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1547 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1548 (fd.o #89222, Simon McVittie)
1550 D-Bus 1.9.12 (2015-02-19)
1553 The “monster lasagna” release.
1557 • Ducktype and yelp-tools are now required to build complete documentation
1558 (they are optional for normal builds).
1562 • D-Bus Specification version 0.26
1563 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1564 · document the BecomeMonitor method
1566 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1567 (fd.o #89041; Tyler Hicks, Simon McVittie)
1569 • On Linux, add support for AppArmor mediation of message sending and
1570 receiving and name ownership (paralleling existing SELinux mediation
1571 support), and eavesdropping (a new check, currently AppArmor-specific)
1572 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1574 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1575 that have printable ASCII contents; we previously only did this for
1576 unterminated bytestrings (fd.o #89109, Simon McVittie)
1578 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1580 • On Windows, add WindowsSID to GetConnectionCredentials
1581 (fd.o #54445, Ralf Habacker)
1583 • Improve clarity of dbus-monitor --profile output and add more columns
1584 (fd.o #89165, Ralf Habacker)
1586 • Add a man page for dbus-test-tool, and build it under CMake as well
1587 as Autotools (fd.o#89086, Simon McVittie)
1589 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1590 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1591 (fd.o #88896, Ralf Habacker)
1595 • Reduce the number of file descriptors used in the fd-passing test,
1596 avoiding failure under the default Linux fd limit, and automatically
1597 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1599 D-Bus 1.9.10 (2015-02-09)
1602 The “sad cyborgs” release.
1604 Security fixes merged from 1.8.16:
1606 • Do not allow non-uid-0 processes to send forged ActivationFailure
1607 messages. On Linux systems with systemd activation, this would
1608 allow a local denial of service: unprivileged processes could
1609 flood the bus with these forged messages, winning the race with
1610 the actual service activation and causing an error reply
1611 to be sent back when service auto-activation was requested.
1612 This does not prevent the real service from being started,
1613 so the attack only works while the real service is not running.
1614 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1618 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1619 similar tools receive messages without altering the security properties
1620 of the system bus, by calling the new BecomeMonitor method on a
1621 private connection. This bypasses the normal <allow> and <deny> rules
1622 entirely, so to preserve normal message-privacy assumptions, only root
1623 is allowed to do this on the system bus. Restricted environments,
1624 such as Linux with LSMs, should lock down access to the Monitoring
1625 interface. (fd.o #46787, Simon McVittie)
1627 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1628 dbus-daemon supports it and access permissions allow it.
1629 It still supports the previous approach ("eavesdropping" match rules)
1630 for compatibility with older bus daemons. (fd.o #46787, Simon)
1632 • dbus-monitor can now log the message stream as binary data for later
1633 analysis, with either no extra framing beyond the normal D-Bus headers,
1634 or libpcap-compatible framing treating each D-Bus message
1635 as a captured packet. (fd.o #46787, Simon)
1639 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1641 • On Unix, forcibly terminate regression tests after 60 seconds to
1642 prevent them from blocking continuous integration frameworks
1643 (fd.o #46787, Simon)
1645 D-Bus 1.9.8 (2015-02-03)
1648 The “all the types of precipitation” release.
1652 • full test coverage now requires GLib 2.36
1653 • full test coverage now requires PyGI (PyGObject 3,
1654 "import gi.repository.GObject") instead of the
1655 obsolete PyGObject 2 ("import gobject")
1659 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1661 • better regression test coverage, including systemd activation
1662 (fd.o #57952, #88810; Simon McVittie)
1666 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1667 turned off (fd.o #88808, Simon McVittie)
1669 • TCP sockets on Windows no longer fail to listen approximately 1 time
1670 in 256, caused by a logic error that should have always made it fail but
1671 was mitigated by incorrect endianness for the port number
1672 (fd.o #87999, Ralf Habacker)
1674 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1676 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1677 previous 64, completing a previous fix which only worked under
1678 Autotools (fd.o #71297, Ralf Habacker)
1680 • on Windows, if the IP family is unspecified only use IPv4,
1681 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1683 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1685 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1687 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1690 D-Bus 1.9.6 (2015-01-05)
1693 The “I do have a bread knife” release.
1697 • Do not allow calls to UpdateActivationEnvironment from uids other than
1698 the uid of the dbus-daemon. If a system service installs unsafe
1699 security policy rules that allow arbitrary method calls
1700 (such as CVE-2014-8148) then this prevents memory consumption and
1701 possible privilege escalation via UpdateActivationEnvironment.
1703 We believe that in practice, privilege escalation here is avoided
1704 by dbus-daemon-launch-helper sanitizing its environment; but
1705 it seems better to be safe.
1707 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1708 on object paths other than /org/freedesktop/DBus. Some system services
1709 install unsafe security policy rules that allow arbitrary method calls
1710 to any destination, method and interface with a specified object path;
1711 while less bad than allowing arbitrary method calls, these security
1712 policies are still harmful, since dbus-daemon normally offers the
1713 same API on all object paths and other system services might behave
1718 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1719 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1721 D-Bus 1.9.4 (2014-11-24)
1724 The “extra-sturdy caramel” release.
1728 • Partially revert the CVE-2014-3639 patch by increasing the default
1729 authentication timeout on the system bus from 5 seconds back to 30
1730 seconds, since this has been reported to cause boot regressions for
1731 some users, mostly with parallel boot (systemd) on slower hardware.
1733 On fast systems where local users are considered particularly hostile,
1734 administrators can return to the 5 second timeout (or any other value
1735 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1738 <limit name="auth_timeout">5000</limit>
1741 (fd.o #86431, Simon McVittie)
1743 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1744 (fd.o #86431, Simon McVittie)
1746 • Send back an AccessDenied error if the addressed recipient is not allowed
1747 to receive a message (and in builds with assertions enabled, don't
1748 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1750 D-Bus 1.9.2 (2014-11-10)
1753 The “structurally unsound flapjack” release.
1757 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1758 so that CVE-2014-3636 part A cannot exhaust the system bus'
1759 file descriptors, completing the incomplete fix in 1.8.8.
1760 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1764 • D-Bus Specification version 0.25
1765 · new value 'const' for EmitsChangedSignal annotation
1766 (fd.o #72958, Lennart Poettering)
1767 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1768 (fd.o #83449; Lennart Poettering, Simon McVittie)
1769 · annotate table of types with reserved/basic/container, and for
1770 basic types, fixed/string-like
1771 · clarify arbitrary limits by quoting them in mebibytes
1773 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1774 (fd.o #83449, Simon McVittie)
1776 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1777 useful for debugging and performance testing:
1778 · dbus-test-tool spam: send repeated messages
1779 · dbus-test-tool echo: send an empty reply for all method calls
1780 · dbus-test-tool black-hole: do not reply to method calls
1781 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1783 • Add support for process ID in credentials-passing on NetBSD
1784 (fd.o #69702, Patrick Welche)
1786 • Add an example script to find potentially undesired match rules
1787 (fd.o #84598, Alban Crequy)
1789 • Document the central assumption that makes our use of credentials-passing
1790 secure (fd.o #83499, Simon McVittie)
1792 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1793 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1798 • Use a less confusing NoReply message when disconnected with a reply pending
1799 (fd.o #76112, Simon McVittie)
1801 • Make the .pc file relocatable by letting pkg-config do all variable
1802 expansion itself (fd.o #75858, Руслан Ижбулатов)
1804 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1805 (fd.o #85563, Patrick Welche)
1807 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1809 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1810 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1812 • Do not fail the tests if a parent process has leaked non-close-on-exec
1813 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1815 • Do not fail the tests on Unix platforms with incomplete
1816 credentials-passing support, but do fail if we can't pass credentials
1817 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1818 (fd.o #69702, Simon McVittie)
1820 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1821 when building with cmake, and expand test coverage there
1822 (fd.o #73689; Ralf Habacker, Simon McVittie)
1824 D-Bus 1.9.0 (2014-10-01)
1827 The “tiered cheeses” release.
1831 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1832 requires either the libsystemd or libsd-daemon shared library, dropping the
1833 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1835 Build-time configuration changes:
1837 • The Stats interface is now enabled by default, and locked-down to
1838 root-only on the system bus. Configure with --disable-stats
1839 to disable it altogether on memory- or disk-constrained systems,
1840 or see ${docdir}/examples/ to open it up to non-root users on the
1841 system bus or restrict access on the session bus.
1842 (fd.o #80759; Simon McVittie, Alban Crequy)
1844 • The CMake build system now builds the same shared library name as Autotools
1845 on at least Linux and Windows:
1846 - on Linux (and perhaps other Unix platforms), it previously built
1847 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1848 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1849 - on Windows, it previously built either libdbus-1.dll (release) or
1850 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1851 libdbus-1.dll for compatibility with older applications.
1852 (fd.o #74117, Ralf Habacker)
1856 • D-Bus Specification version 0.24
1857 · document how to quote match rules (fd.o #24307, Simon McVittie)
1858 · explicitly say that most message types never expect a reply
1859 regardles of whether they have NO_REPLY_EXPECTED
1860 (fd.o #75749, Simon McVittie)
1862 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
1863 initial latency (fd.o #75544, Matt Hoosier)
1865 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
1866 (fd.o #69702, Patrick Welche)
1868 • in dbus-monitor, print more information about file descriptors
1869 (fd.o #80603, Alban Crequy)
1871 • do not install system bus configuration if built for Windows
1872 (fd.o #83583; Ralf Habacker, Simon McVittie)
1874 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
1876 • Add a regression test for file descriptor passing (fd.o #83622,
1881 • fix an incorrect error message if a Unix socket path is too long
1882 (fd.o #73887, Antoine Jacoutot)
1884 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
1885 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
1887 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
1888 in ps(1) (fd.o #69716, Chengwei Yang)
1890 • avoid calling poll() with timeout < -1, which is considered invalid
1891 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
1893 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
1894 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
1895 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
1897 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
1899 • Documentation improvements
1900 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
1902 • in dbus-monitor, do not leak file descriptors that we have monitored
1903 (fd.o #80603, Alban Crequy)
1905 • Set the close-on-exec flag for the inotify file descriptor, even
1906 if built with CMake or older libc (fd.o #73689, Simon McVittie)
1908 • Remove some LGPL code from the Windows dbus-daemon
1909 (fd.o #57272, Ralf Habacker)
1911 D-Bus 1.8.8 (2014-09-16)
1914 The "smashy smashy egg man" release.
1918 • Do not accept an extra fd in the padding of a cmsg message, which
1919 could lead to a 4-byte heap buffer overrun.
1920 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1922 • Reduce default for maximum Unix file descriptors passed per message
1923 from 1024 to 16, preventing a uid with the default maximum number of
1924 connections from exhausting the system bus' file descriptors under
1925 Linux's default rlimit. Distributors or system administrators with a
1926 more restrictive fd limit may wish to reduce these limits further.
1928 Additionally, on Linux this prevents a second denial of service
1929 in which the dbus-daemon can be made to exceed the maximum number
1930 of fds per sendmsg() and disconnect the process that would have
1932 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1934 • Disconnect connections that still have a fd pending unmarshalling after
1935 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1936 removing the possibility of creating an abusive connection that cannot be
1937 disconnected by setting up a circular reference to a connection's
1939 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1941 • Reduce default for maximum pending replies per connection from 8192 to 128,
1942 mitigating an algorithmic complexity denial-of-service attack
1943 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1945 • Reduce default for authentication timeout on the system bus from
1946 30 seconds to 5 seconds, avoiding denial of service by using up
1947 all unauthenticated connection slots; and when all unauthenticated
1948 connection slots are used up, make new connection attempts block
1949 instead of disconnecting them.
1950 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1954 • Check for libsystemd from systemd >= 209, falling back to
1955 the older separate libraries if not found (Umut Tezduyar Lindskog,
1958 • On Linux, use prctl() to disable core dumps from a test executable
1959 that deliberately raises SIGSEGV to test dbus-daemon's handling
1960 of that condition (fd.o #83772, Simon McVittie)
1962 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
1965 • Improve documentation for running tests on Windows (fd.o #41252,
1968 D-Bus 1.8.6 (2014-06-02)
1973 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1974 the message. This prevents an attack in which a malicious client can
1975 make dbus-daemon disconnect a system service, which is a local
1977 (fd.o #80163, CVE-2014-3532; Alban Crequy)
1979 • Track remaining Unix file descriptors correctly when more than one
1980 message in quick succession contains fds. This prevents another attack
1981 in which a malicious client can make dbus-daemon disconnect a system
1983 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
1984 Simon McVittie, Alban Crequy)
1988 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
1989 attach to a session, kill the dbus-daemon as intended
1990 (fd.o #74698, Роман Донченко)
1992 D-Bus 1.8.4 (2014-06-10)
1997 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1998 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1999 Additionally, in highly unusual environments the same flaw could lead to
2000 a side channel between processes that should not be able to communicate.
2001 (CVE-2014-3477, fd.o #78979)
2003 D-Bus 1.8.2 (2014-04-30)
2006 The “nobody wants red” release.
2010 • in the CMake build system, add some hints for Linux users cross-compiling
2011 Windows D-Bus binaries to be able to run tests under Wine
2012 (fd.o #41252, Ralf Habacker)
2014 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
2018 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
2019 to /var/lib/dbus/machine-id instead of generating an entirely new ID
2020 (fd.o #77941, Simon McVittie)
2022 • if dbus-launch receives an X error very quickly, do not kill
2023 unrelated processes (fd.o #74698, Роман Донченко)
2025 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
2026 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
2028 • cope with \r\n newlines in regression tests, since on Windows,
2029 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
2031 D-Bus 1.8.0 (2014-01-20)
2034 The “Wolverine distrusts my printer” release.
2036 This starts a new stable branch. The 1.6.x branch is now considered to be
2037 outdated, and will only receive fixes for serious bugs such as security
2038 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
2039 are unlikely to get any more releases, but if distributors still need to
2040 support them, please share security patches via upstream.
2042 Summary of changes since 1.6.x:
2044 • libdbus always behaves as if dbus_threads_init_default() had been called
2045 (thread-safety by default)
2046 • new dbus-run-session tool, replacing certain misuses of dbus-launch
2047 • dbus-monitor can talk to outdated versions of dbus-daemon again
2048 • new org.freedesktop.DBus.GetConnectionCredentials method
2049 • GetConnectionUnixProcessID also works correctly on Windows, returning
2050 the Windows process ID
2051 • GetConnectionWindowsSID returns the correct SID on Windows
2052 • expat is required, libxml2 can no longer be used as a substitute
2053 • the userDB cache is required, and cannot be disabled
2054 • a 64-bit integer type (either int, long, long long or _int64) is required
2055 • better systemd-journald integration on Linux
2056 • fixed long-standing fd and array leaks when failing to parse a message
2057 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
2058 when using certain object-path allocation patterns, notably in Avahi
2059 • better defaults for Windows support
2060 • better CMake support
2061 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
2062 • the source language for the man pages is now Docbook XML
2064 Enhancements since 1.7.10:
2066 • Enhance the CMake build system to check for GLib and compile/run
2067 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
2071 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
2074 • fix compilation of systemd journal support on older systemd versions where
2075 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
2077 • fix compilation on older MSVC versions by including stdlib.h
2078 (fd.o #73455, Ralf Habacker)
2080 • Allow <allow_anonymous/> to appear in an included configuration file
2081 (fd.o #73475, Matt Hoosier)
2083 Test behaviour changes since 1.7.10:
2085 • If the tests crash with an assertion failure, they no longer default to
2086 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
2087 environment if you want the old behaviour.
2089 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
2090 can be run with an external dbus-daemon by setting
2091 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
2092 an unusually-configured dbus-daemon are skipped.
2094 D-Bus 1.7.10 (2014-01-06)
2097 The “weighted companion cube” release.
2099 This is a release candidate for D-Bus 1.8.
2101 D-Bus Specification 0.23:
2103 • don't require messages with no INTERFACE to be dispatched
2104 (fd.o #68597, Simon McVittie)
2106 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
2109 • define "listenable" and "connectable" addresses, and discuss
2110 the difference (fd.o #61303, Simon McVittie)
2114 • support printing Unix file descriptors in dbus-send, dbus-monitor
2115 (fd.o #70592, Robert Ancell)
2117 • don't install systemd units if --disable-systemd is given
2118 (fd.o #71818, Chengwei Yang)
2122 • don't leak memory on out-of-memory while listing activatable or
2123 active services (fd.o #71526, Radoslaw Pajak)
2125 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
2127 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
2129 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
2130 and DBUS__SEND_MSG are numerically equal to their values in the
2131 reference policy (fd.o #88719, osmond sun)
2133 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
2134 (fd.o #71366, Matt Fischer)
2136 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
2137 winsock2.h (fd.o #71405, Matt Fischer)
2139 • do not return failure from _dbus_read_nonce() with no error set,
2140 preventing a potential crash (fd.o #72298, Chengwei Yang)
2142 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
2143 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
2145 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
2146 which doesn't do anything anyway on at least Linux and FreeBSD
2147 (fd.o #69492, Simon McVittie)
2149 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
2150 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
2151 for credentials more correctly (fd.o #69492, Simon McVittie)
2153 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
2154 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
2157 • refresh cached policy rules for existing connections when bus
2158 configuration changes (fd.o #39463, Chengwei Yang)
2160 D-Bus 1.7.8 (2013-11-01)
2163 The “extreme hills” release.
2167 • If systemd support is enabled, libsystemd-journal is now required.
2171 • When activating a non-systemd service under systemd, annotate its
2172 stdout/stderr with its bus name in the Journal. Known limitation:
2173 because the socket is opened before forking, the process will still be
2174 logged as if it had dbus-daemon's process ID and user ID.
2175 (fd.o #68559, Chengwei Yang)
2177 • Document more configuration elements in dbus-daemon(1)
2178 (fd.o #69125, Chengwei Yang)
2182 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
2183 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
2185 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
2186 disallowed method calls to the audit log, fixing a regression in 1.7.6
2187 (fd.o #49062, Colin Walters)
2189 • path_namespace='/' in match rules incorrectly matched nothing; it
2190 now matches everything. (fd.o #70799, Simon McVittie)
2192 D-Bus 1.7.6 (2013-10-09)
2195 The “CSI Shrewsbury” release.
2197 Build-time configuration changes:
2199 • Directory change notification via dnotify on Linux is no longer
2200 supported; it hadn't compiled successfully since 2010 in any case.
2201 If you don't have inotify (Linux) or kqueue (*BSD), you will need
2202 to send SIGHUP to the dbus-daemon when its configuration changes.
2203 (fd.o #33001, Chengwei Yang)
2205 • Compiling with --disable-userdb-cache is no longer supported;
2206 it didn't work since at least 2008, and would lead to an extremely
2207 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
2210 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
2211 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
2212 with the Autotools build system. (fd.o #66142, Chengwei Yang)
2214 • --with-valgrind=auto enables Valgrind instrumentation if and only if
2215 valgrind headers are available. The default is still --with-valgrind=no.
2216 (fd.o #56925, Simon McVittie)
2220 • Platforms with no 64-bit integer type are no longer supported.
2221 (fd.o #65429, Simon McVittie)
2223 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
2225 • Full test coverage no longer requires dbus-glib, although the tests do not
2226 exercise the shared library (only a static copy) if dbus-glib is missing.
2227 (fd.o #68852, Simon McVittie)
2231 • D-Bus Specification 0.22
2232 · Document GetAdtAuditSessionData() and
2233 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
2234 · Fix example .service file (fd.o #66481, Chengwei Yang)
2235 · Don't claim D-Bus is "low-latency" (lower than what?), just
2236 give factual statements about it supporting async use
2237 (fd.o #65141, Justin Lee)
2238 · Document the contents of .service files, and the fact that
2239 system services' filenames are constrained
2240 (fd.o #66608; Simon McVittie, Chengwei Yang)
2242 • Be thread-safe by default on all platforms, even if
2243 dbus_threads_init_default() has not been called. For compatibility with
2244 older libdbus, library users should continue to call
2245 dbus_threads_init_default(): it is harmless to do so.
2246 (fd.o #54972, Simon McVittie)
2248 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
2250 • New API: dbus_setenv(), a simple wrapper around setenv().
2251 Note that this is not thread-safe. (fd.o #39196, Simon)
2253 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
2254 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
2255 (connect to a given bus, like dbus-monitor --address=ADDRESS).
2256 dbus-send --address still exists for backwards compatibility,
2257 but is no longer documented. (fd.o #48816, Andrey Mazo)
2260 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
2265 • Avoid an infinite busy-loop if a signal interrupts waitpid()
2266 (fd.o #68945, Simon McVittie)
2268 • Clean up memory for parent nodes when objects are unexported
2269 (fd.o #60176, Thomas Fitzsimmons)
2271 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
2272 documented. Previously, it assumed its second parameter was TRUE.
2273 (fd.o #69165, Chengwei Yang)
2275 • Escape addresses containing non-ASCII characters correctly
2276 (fd.o #53499, Chengwei Yang)
2278 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)

2369 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
2370 of service for system services. Vulnerability reported by Alexandru Cornea.
2375 • The Windows version of libdbus now contains a C++ source file, used
2376 to provide global initialization when the library is loaded.
2377 gcc (mingw*) users should ensure that g++ is also installed.
2379 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
2380 and was never the recommended option) has been removed. Expat is now a
2385 • It should now be safe to call dbus_threads_init_default() from any thread,
2386 at any time. Authors of loadable modules and plugins that use libdbus
2387 should consider doing so during initialization.
2388 (fd.o #54972, Simon McVittie)
2390 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
2394 · dbus-run-session: experimental new tool to start a temporary D-Bus
2395 session, e.g. for regression tests or a text console, replacing
2396 certain uses of dbus-launch which weren't really correct

2408 · Fix an assertion failure if we try to activate systemd services before
2409 systemd connects to the bus (fd.o #50199, Chengwei Yang)
2410 · Avoid compiler warnings for ignoring the return from write()
2414 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/

2469 The "Disingenuous Assertions" release.
2471 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
2472 remains the recommended version for long-term-supported distributions
2473 or the upcoming GNOME 3.8 release.
2475 Build-time configuration changes:
2477 • The --with-dbus-session-bus-default-address configure option is no longer
2478 supported. Use the new --with-dbus-session-bus-connect-address and
2479 --with-dbus-session-bus-listen-address options instead. On Windows, you
2480 usually want them to have the same argument; on Unix, the defaults are
2483 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2484 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2485 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2487 • cmake/cross-compile.sh has been removed. Instead, please use a
2488 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2489 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2490 as documented in "info automake Cross-Compilation", and set
2491 PKG_CONFIG_PATH appropriately.
2495 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
2496 • man2html is no longer used.

2502 implements o.fd.DBus (fd.o #51865, Colin Walters)
2503 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
2504 · stop claiming that all basic types work just like INT32 (strings don't!)
2506 • The "source code" for the man pages is now Docbook XML, eliminating
2507 the outdated duplicate copies used when building with CMake.
2508 (fd.o #59805; Ralf Habacker, Simon McVittie)
2512 • In the activation helper, when compiled for tests, do not reset the system
2513 bus address, fixing the regression tests. (fd.o #52202, Simon)
2515 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
2516 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
2518 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

2537 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
2540 · The default session bus listening and connecting address is now
2541 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2542 and GDBus "out of the box". Use the configure options and cmake variables
2543 described above if you require a different autolaunch scope.
2544 (fd.o #38201, Simon McVittie)
2545 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
2547 • Create session.d, system.d directories under CMake (fd.o #41319,
2550 D-Bus 1.6.8 (2012-09-28)
2553 The "Fix one thing, break another" release.
2555 • Follow up to CVE-2012-3524: The additional hardening
2556 work to use __secure_getenv() as a followup to bug #52202
2557 broke certain configurations of gnome-keyring. Given
2558 the difficulty of making this work without extensive
2559 changes to gnome-keyring, use of __secure_getenv() is

2603 • Disconnect "developer mode" (assertions, verbose mode etc.) from
2604 Automake maintainer mode. D-Bus developers should now configure with
2605 --enable-developer. Automake maintainer mode is now on by default;
2606 distributions can disable it with --disable-maintainer-mode.
2607 (fd.o #34671, Simon McVittie)
2609 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
2610 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
2613 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
2615 D-Bus 1.6.0 (2012-06-05)
2618 The “soul of this machine has improved” release.
2620 This version starts a new stable branch of D-Bus: only bug fixes will
2621 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
2623 Summary of changes since 1.4.x:

2652 · dbus_threads_init() ignores its argument and behaves like
2653 dbus_threads_init_default() instead
2654 · removed the per-connection link cache, improving dbus-daemon performance
2656 • Developer features
2657 · optional Valgrind instrumentation (--with-valgrind)

2662 Changes since 1.5.12:
2664 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
2665 spec-compliance (fd.o #48580, David Zeuthen)
2667 • Don't use install(1) within the source/build trees, fixing the build as
2668 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
2670 • Add missing commas in some tcp and nonce-tcp addresses, and remove
2671 an unused duplicate copy of the nonce-tcp transport in Windows builds
2672 (fd.o #45896, Simon McVittie)
2674 D-Bus 1.5.12 (2012-03-27)
2677 The “Big Book of Science” release.
2679 • Add public API to validate various string types:
2680 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),

2682 (fd.o #39549, Simon McVittie)
2684 • Turn DBusBasicValue into public API so bindings don't need to invent their
2685 own "union of everything" type (fd.o #11191, Simon McVittie)
2687 • Enumerate data files included in the build rather than using find(1)
2688 (fd.o #33840, Simon McVittie)
2690 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
2691 in dbus-daemon (fd.o #46273, Alban Crequy)

2696 · fix duplicate case value when compiling against mingw-w64
2697 (fd.o #47321, Andoni Morales Alastruey)
2699 D-Bus 1.5.10 (2012-02-21)
2702 The "fire in Delerium" release.
2704 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2705 and SUSv2) is now required.
2707 • D-Bus Specification 0.19:
2708 · Formally define unique connection names and well-known bus names,
2709 and document best practices for interface, bus, member and error names,
2710 and object paths (fd.o #37095, Simon McVittie)
2711 · Document the search path for session and system services on Unix, and
2712 where they should be installed by build systems (fd.o #21620, fd.o #35306;
2714 · Document the systemd transport (fd.o #35232, Lennart Poettering)
2716 • Make dbus_threads_init() use the same built-in threading implementation
2717 as dbus_threads_init_default(); the user-specified primitives that it
2718 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
2720 • Allow all configured auth mechanisms, not just one (fd.o #45106,
2723 • Improve cmake build system (Ralf Habacker):
2724 · simplify XML parser dependencies (fd.o #41027)
2725 · generate build timestamp (fd.o #41029)
2726 · only create batch files on Windows
2727 · fix option and cache syntax
2728 · add help-options target
2729 · share dbus-arch-deps.h.in with autotools rather than having our
2730 own version (fd.o #41033)
2732 • Build tests successfully with older GLib, as found in e.g. Debian 6
2733 (fd.o #41219, Simon McVittie)
2735 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
2737 • Build documentation correctly if man2html doesn't support filenames on
2738 its command-line (fd.o #43875, Jack Nagel)
2740 • Improve test coverage. To get even more coverage, run the tests with
2741 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
2743 • Reduce the size of the shared library by moving functionality only used
2744 by dbus-daemon, tests etc. into their internal library and deleting
2745 unused code (fd.o #34976, #39759; Simon McVittie)
2747 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2748 setups where the default configuration must include <pidfile/> to avoid
2749 breaking traditional init, but the pid file is in fact unnecessary; use
2750 it under systemd to improve startup time a bit (fd.o #45520,
2753 • Optionally (if configured --with-valgrind) add instrumentation to debug
2754 libdbus and associated tools more meaningfully under Valgrind
2755 (fd.o #37286, Simon McVittie)
2757 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
2759 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
2761 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
2762 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
2763 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
2766 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
2770 · Replace our broken reimplementation of recursive mutexes, which has
2771 been broken since 2006, with an ordinary pthreads recursive mutex
2772 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2773 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2774 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2775 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2776 · When running under systemd, use it instead of ConsoleKit to check
2777 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2778 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2779 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2780 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2781 (fd.o #41218, Simon McVittie)
2782 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2783 helper doesn't obey environment variables to avoid privilege escalation
2784 attacks, so make the system bus follow the same rules
2785 (fd.o #21620, Simon McVittie)
2788 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2789 Jesper Dam, Ralf Habacker)
2790 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
2793 D-Bus 1.5.8 (2011-09-21)
2796 The "cross-metering" release.
2798 In addition to dead code removal and refactoring, this release contains all
2799 of the bugfixes from 1.4.16.
2801 • Clean up dead code, and make more warnings fatal in development builds
2802 (fd.o #39231, fd.o #41012; Simon McVittie)
2804 • If full test coverage is requested via --enable-tests, strictly require
2805 Python, pygobject and dbus-python, which are required by some tests; if not,
2806 and Python is missing, skip those tests rather than failing
2807 (fd.o #37847, Simon McVittie)

2828 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2829 Brian Cameron, Simon McVittie)
2830 · On systems that use libcap-ng but not systemd, drop supplemental groups
2831 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2832 · Make the cmake build work again on GNU platforms (fd.o #29228,

2849 D-Bus 1.5.6 (2011-07-29)
2852 The "weird, gravy-like aftertaste" release.
2854 In addition to new features and refactoring, this release contains all of the
2855 bugfixes from 1.4.14.
2857 Potentially incompatible (Bustle and similar debugging tools will need
2858 changes to work as intended):
2860 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2861 different recipient) by mistake: eavesdroppers must now opt-in to this
2862 behaviour by putting "eavesdrop='true'" in the match rule, which will
2863 not have any practical effect on buses where eavesdropping is not allowed
2864 (fd.o #37890, Cosimo Alfarano)
2868 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2869 Cosimo Alfarano, Simon McVittie)
2870 · add the "eavesdrop" keyword to match rules
2871 · define eavesdropping, unicast messages and broadcast messages
2872 · stop claiming that match rules are needed to match unicast messages to you
2873 · promote the type system to be a top-level section
2875 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2876 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2877 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2879 • Consistently use atomic operations on everything that is ever manipulated
2880 via atomic ops, as was done for changes to DBusConnection's refcount in
2881 1.4.12 (fd.o #38005, Simon McVittie)
2883 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2886 • Make "make check" in a clean tree work, by not running tests until
2887 test data has been set up (fd.o #34405, Simon McVittie)
2889 • The dbus-daemon no longer busy-loops if it has a very large number of file
2890 descriptors (fd.o #23194, Simon McVittie)
2892 • Refactor message flow through dispatching to avoid locking violations if
2893 the bus daemon's message limit is hit; remove the per-connection link cache,
2894 which was meant to improve performance, but now reduces it (fd.o #34393,
2897 • Some cmake fixes (Ralf Habacker)
2899 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2900 Simon McVittie, Lennart Poettering)
2902 • Stop storing two extra byte order indicators in each D-Bus message
2903 (fd.o #38287, Simon McVittie)
2905 • Add an optional Stats interface which can be used to get statistics from
2906 a running dbus-daemon if enabled at configure time with --enable-stats
2907 (fd.o #34040, Simon McVittie)
2909 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2911 • Documentation (fd.o #36156, Simon McVittie):
2912 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2913 · install more documentation automatically, including man2html output
2914 · put dbus.devhelp in the right place (it must go in ${htmldir})
2917 · look for system services in /lib/dbus-1/system-services in addition to all
2918 the other well-known locations; note that this should always be /lib,
2919 even on platforms where shared libraries on the root FS would go in /lib64,
2920 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2921 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2923 • Windows-specific (Ralf Habacker):
2924 · fix use of a mutex for autolaunch server detection
2925 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2927 D-Bus 1.5.4 (2011-06-10)
2930 Security (local denial of service):
2932 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2933 local DoS if foreign-endian messages are relayed through the dbus-daemon
2934 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2935 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2939 • The constant to use for an infinite timeout now has a name,
2940 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2941 which can be used for source compatibility with older versions of libdbus.
2943 • If GLib and DBus-GLib are already installed, more tests will be built,
2944 providing better coverage. The new tests can also be installed via
2945 ./configure --enable-installed-tests
2946 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2950 • Consistently use atomic operations for the DBusConnection's refcount,
2951 fixing potential threading problems (fd.o #38005, Simon McVittie)
2953 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2954 small (300KiB on x86-64) and it frequently doesn't work in unusual
2955 toolchains. To optimize for minimum installed size, you should benchmark
2956 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2957 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2959 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2960 (fd.o #35880, Timothy Redaelli)
2962 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2963 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2965 • Windows-specific changes:
2966 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2968 D-Bus 1.5.2 (2011-06-01)
2971 The "Boar Hunter" release.
2973 Notes for distributors:
2975 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2976 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2977 toolchain supports it reliably, via something like:
2979 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2981 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2985 • D-Bus Specification v0.17
2986 · Reserve the extra characters used in signatures by GVariant
2987 (fd.o #34529, Simon McVittie)
2988 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2989 • Don't force -fPIE: distributions and libtool know better than we do whether
2990 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2991 • Allow --disable-gc-sections, in case your toolchain offers the
2992 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2993 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2994 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2995 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2996 • Ensure that maintainers upload documentation with the right permissions
2997 (fd.o #36130, Simon McVittie)

3002 • Log messages dropped due to quotas to syslog (fd.o #35358,
3004 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
3005 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
3006 (fd.o #35228, Lennart Poettering)
3007 • In the regression tests, don't report fds as "leaked" if they were open
3008 on startup (fd.o #35173, Simon McVittie)
3009 • Make dbus-monitor bail out if asked to monitor more than one bus,
3010 rather than silently using the last one (fd.o #26548, Will Thompson)
3011 • Clarify documentation (fd.o #35182, Simon McVittie)
3012 • Clean up minor dead code and some incorrect error handling
3013 (fd.o #33128, fd.o #29881; Simon McVittie)
3014 • Check that compiler options are supported before using them (fd.o #19681,
3017 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
3019 D-Bus 1.5.0 (2011-04-11)
3022 The "you never know when you need to tow something from your giant
3023 flying shark" release.
3025 • D-Bus Specification v0.16
3026 · Add support for path_namespace and arg0namespace in match rules
3027 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
3028 · Make argNpath support object paths, not just object-path-like strings,
3029 and document it better (fd.o #31818, Will Thompson)
3030 • Let the bus daemon implement more than one interface (fd.o #33757,
3032 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
3034 • Require user intervention to compile with missing 64-bit support
3035 (fd.o #35114, Simon McVittie)
3036 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
3037 • Raise UnknownObject instead of UnknownMethod for calls to methods on
3038 paths that are not part of the object tree, and UnknownInterface for calls
3039 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
3041 D-Bus 1.4.8 (2011-04-08)
3044 The "It's like the beginning of a lobster" release.
3046 • Rename configure.in to configure.ac, and update it to modern conventions
3047 (fd.o #32245; Javier Jardón, Simon McVittie)
3048 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
3050 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
3051 --disable-x11-autolaunch configure option to prevent it altogether
3052 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
3053 • Install the documentation, and an index for Devhelp (fd.o #13495,
3054 Debian #454142; Simon McVittie, Matthias Clasen)
3055 • If checks are not disabled, check validity of string-like types and
3056 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
3057 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
3058 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
3059 • Break up a huge conditional in config-parser so gcov can produce coverage
3060 data (fd.o #10887, Simon McVittie)
3061 • List which parts of the Desktop Entry specification are applicable to
3062 .service files (fd.o #19159, Sven Herzberg)
3063 • Don't suppress service activation if two services have the same Exec=
3064 (fd.o #35750, Colin Walters)

3074 The "1, 2, miss a few, 99, 100" release.
3076 • Remove unfinished changes intended to support GTest-based tests,
3077 which were mistakenly included in 1.4.4
3079 D-Bus 1.4.4 (2010-02-17)
3082 • Switch back to using even micro versions for stable releases; 1.4.1
3083 should have been called 1.4.2, so skip that version number
3084 • Don't leave bad file descriptors being watched when spawning processes,
3085 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
3086 also LP#656134, LP#680444, LP#713157)
3087 • Check for MSG_NOSIGNAL correctly
3088 • Fix failure to detect abstract socket support (fd.o #29895)
3089 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
3090 (fd.o #32262, NB#180486)

3120 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
3121 crash the bus. The existing restriction to 64-levels of nesting previously
3122 only applied to the static type signature; now it also applies to dynamic
3123 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
3125 • OS X portability fixes, including launchd support.
