1 dbus 1.12.12 (UNRELEASED)
2 =========================
6 • Remove __attribute__((__malloc__)) attribute on dbus_realloc(),
7 which does not meet the criteria for that attribute in gcc 4.7+,
8 potentially leading to miscompilation (fd.o #107741, Simon McVittie)
10 • Fix some small O(1) memory leaks (fd.o #107320, Simon McVittie)
12 dbus 1.12.10 (2018-08-02)
13 =========================
15 The “beam deflection” release.
19 • Prevent reading up to 3 bytes beyond the end of a truncated message.
20 This could in principle be an information leak or denial of service
21 on the system bus, but is not believed to be exploitable to crash
22 the system bus or leak interesting information in practice.
23 (fd.o #107332, Simon McVittie)
25 • Fix build with gcc 8 -Werror=cast-function-type
26 (fd.o #107349, Simon McVittie)
28 • Fix warning from gcc 8 about suspicious use of strncpy() when
29 populating struct sockaddr_un (fd.o #107350, Simon McVittie)
31 • Fix a minor memory leak when a DBusServer listens on a new address
32 (fd.o #107194, Simon McVittie)
34 • Fix an invalid NULL argument to rmdir() if a nonce-tcp DBusServer
35 runs out of memory (fd.o #107194, Simon McVittie)
37 • Don't use misleading errno-derived error names if getaddrinfo() or
38 getnameinfo() fails with a code other than EAI_SYSTEM
39 (fd.o #106395, Simon McVittie)
41 • Skip tests that require working TCP if we are in a container environment
42 where 127.0.0.1 cannot be resolved (fd.o #106812, Simon McVittie)
44 dbus 1.12.8 (2018-04-30)
45 ========================
47 The “golden super-velociraptor” release.
51 • The Devhelp documentation index is now in version 2 format
52 (fd.o #106186, Simon McVittie)
54 • Give the dbus-daemon man page some scarier warnings about
55 <allow_anonymous/> and non-local TCP, which are insecure and should
56 not be used, particularly for the standard system and session buses
57 (fd.o #106004, Simon McVittie)
61 • Fix installation of Ducktype documentation with newer yelp-build
62 versions (fd.o #106171, Simon McVittie)
64 dbus 1.12.6 (2018-03-01)
65 ========================
67 The “just the one swan, actually” release.
71 • Increase system dbus-daemon's RLIMIT_NOFILE rlimit before it drops
72 privileges, because it won't have permission afterwards. This fixes a
73 regression in dbus 1.10.18 and 1.11.0 which made the standard system bus
74 more susceptible to deliberate or accidental denial of service.
75 (fd.o #105165, David King)
77 dbus 1.12.4 (2018-02-08)
78 ========================
80 The “Stria Campania 115” release.
84 • When iterating the DBusConnection while blocking on a pending call,
85 don't wait for I/O if that pending call already has a result; and make
86 sure that whether it has a result is propagated in a thread-safe way.
87 This prevents certain multi-threaded calling patterns from blocking
88 until their timeout even when they should have succeeded sooner.
89 (fd.o #102839; Manish Narang, Michael Searle)
91 • Report the correct error if OOM is reached while trying to listen
92 on a TCP socket (fd.o #89104, Simon McVittie)
94 • Fix assertion failures in recovery from OOM while setting up a
95 DBusServer (fd.o #89104, Simon McVittie)
97 • Add a missing space to a warning message (fd.o #103729, Thomas Zajic)
99 • Expand ${bindir} correctly when pkg-config is asked for dbus_daemondir
100 (fd.o #104265, Benedikt Heine)
102 • On Linux systems with systemd < 237, if ${localstatedir}/dbus doesn't
103 exist, create it before trying to create ${localstatedir}/dbus/machine-id
104 (fd.o #104577, Chris Lesiak)
106 • Fix escaping in dbus-api-design document (fd.o #104925, Philip Withnall)
108 dbus 1.12.2 (2017-11-13)
109 ========================
111 The “spider pumpkin” release.
115 • Log a warning if a new connection cannot be accepted due to an
116 out-of-memory condition or failure to identify its AppArmor or
117 SELinux context (fd.o #103592, Simon McVittie)
121 • Make use of $(MKDIR_P) compatible with install-sh, fixing build when a
122 GNU-compatible `mkdir -p` is not available (fd.o #103521, ilovezfs)
124 • When building for Windows with Autotools, avoid `echo -e`, fixing
125 cross-compilation on non-GNU platforms like macOS
126 (fd.o #103493, Tony Theodore)
128 • Fix crashes in the server side of the nonce-tcp: transport under
129 various error conditions. This transport should normally only be used
130 on Windows, where AF_UNIX sockets are unavailable; the unix: transport
131 is the only one recommended for production use on Unix platforms.
132 (fd.o #103597, Simon McVittie)
136 • Improve test coverage on Travis-CI (Simon McVittie)
138 dbus 1.12.0 (2017-10-30)
139 ========================
141 The “gingerbread skull” release.
143 1.12.x is a new stable branch, recommended for use in OS
146 Summary of major changes between 1.10.x and 1.12.0
147 --------------------------------------------------
151 • Expat >= 2.1.0 is required.
152 • GLib >= 2.40 is required if full test coverage is enabled.
153 • [Linux] libselinux >= 2.0.86 is required if SELinux support is
155 • [Unix] dbus now requires an <inttypes.h> that defines C99 constants
156 such as PRId64 and PRIu64, except when building for Windows.
157 • [Autotools] Building from git (but not from tarballs) with Autotools
158 now requires macros from the GNU Autoconf Archive.
159 • [CMake] Builds done using CMake now require CMake 3.0.2.
161 Build-time configuration changes:
163 • Expat is now found using pkg-config. See the release notes for
165 • The --disable-compiler-optimisations and --enable-compiler-coverage
166 options no longer exist. See the release notes for 1.11.4 and 1.11.8.
167 • [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
168 options no longer exist. See the release notes for 1.11.20.
169 • [Unix] Flag files in /var/run/console/${username} are no longer
170 checked for at_console by default. See the release notes for 1.11.18.
171 • [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
172 and packagers will now need to add these downstream (most already do).
173 See the release notes for 1.11.18.
174 • [Unix] The process ID file no longer has a different default location
175 on Red Hat derivatives. See the release notes for 1.11.18.
176 • [Unix] ${runstatedir} is now independent of ${localstatedir} with
177 recent Autotools versions. See the release notes for 1.11.16.
178 • [Windows] The WINDRES variable is no longer used. See the release
183 • Eavesdropping is officially deprecated in favour of BecomeMonitor.
184 See the release notes for spec version 0.31 (in dbus 1.11.14).
185 • [Unix] Flag files in /var/run/console/${username} are deprecated.
186 See the release notes for 1.11.18.
190 • <allow> and <deny> rules in dbus-daemon configuration can now
191 include send_broadcast="true", send_broadcast="false",
192 max_unix_fds="N", min_unix_fds="N" (for some integer N).
193 See the release notes for 1.11.18.
194 • dbus_try_get_local_machine_id() is like
195 dbus_get_local_machine_id(), but returns a DBusError.
196 • New APIs around DBusMessageIter to simplify cleanup.
197 See the release notes for 1.11.16.
198 • The message bus daemon now implements the standard Introspectable,
199 Peer and Properties interfaces. See the release notes for
200 dbus 1.11.14 and spec version 0.31.
201 • DTDs for introspection XML and bus configuration are installed.
202 • dbus can be compiled to be relocatable, making it more suitable for
203 binary bundling with other software. On Windows, this is on by
205 • [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
206 never uses Linux abstract sockets, which is advantageous for
207 containers. On non-Linux it is equivalent to unix:tmpdir=….
208 See the release notes for dbus 1.11.14 and spec version 0.31.
209 • [Unix] New option "dbus-launch --exit-with-x11".
210 • [Unix] Session managers can create transient .service files in
211 $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
212 • [Unix] A sysusers.d snippet can create the messagebus user on-demand.
214 Miscellaneous behaviour changes:
216 • [Unix] The session bus now logs to syslog if it was started by
218 • [Unix] Internal warnings are logged to syslog if configured.
219 • [Unix] Exceeding an anti-DoS limit is logged to syslog if configured,
222 Changes since 1.11.22 release candidate
223 ---------------------------------------
225 Standard stable-branch changes:
227 • Disable warnings about use of deprecated functions (Simon McVittie)
231 • Don't distribute files generated by ./configure in the source tarball
232 (fd.o #103420, Simon McVittie)
236 • Remove some unused files from the git repository
237 (fd.o #103420, Simon McVittie)
239 D-Bus 1.11.22 (2017-10-23)
240 ==========================
242 The “fire surface” release.
244 This is the first release-candidate for the 1.12.0 stable release.
246 Build-time configuration changes:
248 • When building for Windows with Autotools, setting the WINDRES variable
249 no longer works to select a non-standard resource compiler. Use
250 libtool's standard RC variable instead, for example
251 "./configure RC=i686-w64-mingw32-windres"
255 • Builds done using CMake now require CMake 3.0.2.
259 • When building for Windows, improve quality of metadata in
260 libdbus-1-3.dll (fd.o #103015, Ralf Habacker)
264 • Fix a typo "uint 16" in dbus-send(1) man page
265 (fd.o #103075, David King)
267 • When building for Windows, libdbus-1-3.dll always includes version
268 information. Previously, this was missing if using CMake and any
269 non-MSVC compiler. (fd.o #103015, Ralf Habacker)
271 • Fix the build with MSVC, which regressed with the #102558 fix in
272 1.11.20. (fd.o #102558, Ralf Habacker)
276 • Simplify Windows resource embedding
277 (fd.o #103015, Simon McVittie)
279 D-Bus 1.11.20 (2017-10-03)
282 The “wraith stun” release.
284 Build-time configuration changes:
286 • The --enable-abstract-sockets and --disable-abstract-sockets options
287 no longer exist. Support for Linux's abstract AF_UNIX sockets is now
288 unconditionally enabled on Linux and disabled everywhere else.
289 (fd.o #34905, Simon McVittie)
293 • Make slower tests less likely to time out, and improve diagnostics if
294 tests do time out (fd.o #103009, Simon McVittie)
296 • On Windows, don't compile an unused stub implementation of
297 _dbus_set_signal_handler() (fd.o #103010, Simon McVittie)
301 • Be more careful to save and restore errno in POSIX async signal
302 handlers (fd.o #103010, Simon McVittie)
304 • On Windows, embed a manifest in dbus-update-activation-environment.exe
305 so that the heuristics used for UAC do not assume it needs elevated
306 privileges due to its name containing "update"
307 (fd.o #102558, Ralf Habacker)
309 • On Windows with Automake, embed version information in libdbus-1,
310 as was meant to happen in all versions since 2009
311 (fd.o #103015, Simon McVittie)
313 D-Bus 1.11.18 (2017-09-25)
316 The “vampire conquistador” release.
318 Build-time configuration changes:
320 • By default, dbus-daemon on Unix no longer checks for flag files
321 /var/run/console/${username} created by the obsolete pam_console and
322 pam_foreground PAM modules when deciding whether ${username} is
323 currently at the console. The old default behaviour can be restored
324 by specifying --with-console-auth-dir=/var/run/console in the
325 recommended Autotools build system, or
326 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
327 now deprecated, and will be removed in dbus 1.13 unless feedback via
328 fd.o #101629 indicates that this would be problematic.
329 (fd.o #101629, Simon McVittie)
331 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
332 script for Cygwin, are no longer provided in the upstream dbus
333 source. We recommend that distributors who support non-systemd service
334 management should maintain their own init scripts or other service
335 manager integration as part of their downstream packaging, similar to
336 the way Debian distributes a Debian-specific LSB init script for dbus.
338 The systemd unit continues to be maintained as part of the upstream
339 dbus source, because it receives regular testing and maintenance.
341 (fd.o #101706, Simon McVittie)
343 • The process ID file created by the system bus is no longer influenced
344 by the --with-init-scripts=redhat configure option or the presence of
345 /etc/redhat-release at build time. If your OS's init script or other
346 service management relies on the Red Hat-style pid file, it can be
347 restored by specifying --with-system-pid-file=/run/messagebus.pid at
348 configure time or using the <pidfile> directive in bus configuration.
350 Note that the upstream-supplied systemd unit runs dbus-daemon with
351 the --nopidfile option, so it does not normally write a pid file,
352 regardless of whether the OS is Red-Hat-derived or not.
354 (fd.o #101706, Simon McVittie)
358 • <allow> and <deny> rules in dbus-daemon configuration can now
359 include send_broadcast="true" or send_broadcast="false", which make
360 the rule only match broadcast signals, or only match messages that
361 are not broadcast signals, respectively.
362 (fd.o #29853, Simon McVittie)
364 • <allow> and <deny> rules can now be configured to apply only to
365 messages with or without Unix file descriptors attached. This would
366 typically be used in rules like these:
367 <allow send_destination="..." max_unix_fds="0"/>
368 <deny send_destination="..." min_unix_fds="1"/>
369 <deny receive_sender="..." min_unix_fds="1"/>
370 but can also be used to set a nonzero upper limit on the number of
372 <allow send_destination="..." max_unix_fds="4"/>
373 (fd.o #101848, Simon McVittie)
375 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
376 now respects the HOME environment variable on the client side, and
377 on the server side when the uid attempting to connect is the same
378 as the uid of the server. This allows the automated tests to pass in
379 environments where the user's "official" home directory in /etc/passwd
380 is nonexistent, such as Debian autobuilders.
381 (fd.o #101960, Simon McVittie)
385 • When parsing dbus-daemon configuration, tell Expat not to use
386 cryptographic-quality entropy as a salt for its hash tables: we trust
387 the configuration files, so we are not concerned about algorithmic
388 complexity attacks via hash table collisions. This prevents
389 dbus-daemon --system from holding up the boot process (and causing
390 early-boot system services like systemd, logind, networkd to time
391 out) on entropy-starved embedded systems.
392 (fd.o #101858, Simon McVittie)
394 • Avoid a -Werror=declaration-after-statement build failure on Solaris
395 (fd.o #102145, Alan Coopersmith)
397 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
398 to LOG_INFO, matching how we use this log level in practice
399 (fd.o #102686, Simon McVittie)
401 D-Bus 1.11.16 (2017-07-27)
404 The “south facing garden” release.
406 Build-time configuration changes:
408 • The Autotools build system now supports varying ${runstatedir}
409 independently of ${localstatedir}, if using an Autoconf version
410 that has that feature; version 2.70 will eventually have this, but
411 many Linux distributions add it to version 2.69 as a patch.
412 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
413 and runstatedir=/run. (fd.o #101569, Simon McVittie)
417 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
418 and dbus_message_iter_abandon_container_if_open() simplify the
419 single-exit-point ("goto out") style of resource cleanup. The API
420 documentation around DBusMessageIter and containers has also been
421 clarified. (fd.o #101568, Simon McVittie)
425 • Fix the implementation of re-enabling a timeout (again) so that its
426 countdown is always restarted as intended. (fd.o #95619,
429 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
430 available to all users on the system bus (fd.o #101700, Simon McVittie)
432 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
433 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
435 • dbus_message_iter_open_container() no longer leaks memory if it runs out
436 of memory. (fd.o #101568, Simon McVittie)
438 • dbus_message_append_args_valist() no longer leaks memory if given an
439 unsupported type. This situation is still considered to be a programming
440 error which needs to be corrected by the user of libdbus.
441 (fd.o #101568, Simon McVittie)
443 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
444 will no longer report that their arguments were invalid if they run out
445 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
447 • Ensure that tests fail if they would otherwise have tried to connect to
448 the real session bus (fd.o #101698, Simon McVittie)
450 • Make build-time tests cope with finding Python 3, but not Python 2
451 (fd.o #101716, Simon McVittie)
453 Internal changes relevant to dbus developers:
455 • DBusVariant is a new mechanism to copy single values from a message into
456 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
458 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
459 Logging an ERROR message does not make the process exit; the caller
460 is responsible for calling abort() or exit(), whichever is more appropriate.
461 (fd.o #101568, Simon McVittie)
463 • Better test coverage (fd.o #101568, Simon McVittie)
465 D-Bus 1.11.14 (2017-06-29)
468 The “irrational fear of bees” release.
472 • Expat >= 2.1.0 is always required
473 • libselinux >= 2.0.86 is required if SELinux support is enabled
474 • GLib >= 2.40 is required if full test coverage is enabled
476 Build-time configuration changes:
478 • We now use pkg-config to find libexpat in Autotools builds. This requires
479 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
480 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
481 itself cause compilation failures.
483 As with all pkg-config-based configure checks, you can use
484 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
485 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
486 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
489 (fd.o #69801, Simon McVittie)
491 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
492 is required due to the removal of explicit refcounting for SIDs.
493 (fd.o #100912, Laurent Bigonville)
497 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
498 as a side-effect of a sufficiently privileged process merely reading the
499 machine ID. It is no longer copied as a side-effect of reading.
500 Running dbus-uuidgen --ensure, which should be done after installing dbus,
501 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
502 former exists and the latter does not.
503 (fd.o #101257, Simon McVittie)
505 • The undocumented Verbose interface, and the GetAllMatchRules method on
506 the undocumented Stats interface, must now be used via the object path
507 /org/freedesktop/DBus. Previously, they existed on all object paths.
508 (fd.o #101257, Simon McVittie)
510 • AddMatch() with a match rule containing eavesdrop='true' will now fail
511 unless called by either the same user as the dbus-daemon, or Unix uid 0
512 (root), matching the restrictions applied to the newer BecomeMonitor()
513 method. On the session bus this has no practical effect. On the system
514 bus this will prevent certain configurations that already did not
515 work well in practice. (fd.o #101567, Simon McVittie)
519 • D-Bus Specification version 0.31
520 · Don't require implementation-specific search paths to be lowest
522 · Correct regex syntax for optionally-escaped bytes in addresses so it
523 includes hyphen-minus, forward slash and underscore as intended
524 · Describe all message bus methods in the same section
525 · Clarify the correct object path for method calls to the message bus
526 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
527 · Document that the message bus implements Introspectable, Peer and
529 · Add new Features and Interfaces properties for message bus
531 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
533 · Don't require eavesdrop='true' to be accepted from connections not
534 sufficiently privileged to use it successfully
535 · Formally deprecate eavesdropping in favour of BecomeMonitor
536 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
537 Simon McVittie, Tom Gundersen)
539 • Implement the Properties and Peer interfaces in dbus-daemon
540 (fd.o #101257, Simon McVittie)
542 • New function dbus_try_get_local_machine_id() is like
543 dbus_get_local_machine_id(), but returning a DBusError. Other code
544 that needs the machine ID will now report a recoverable error (instead
545 of logging to stderr and aborting) if no machine ID is available.
546 Generating a machine ID is still considered to be a required part of
547 installing dbus correctly. (fd.o #13194, Simon McVittie)
549 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
550 (fd.o #101315, Laurent Bigonville)
552 • Avoid deprecated API calls when using SELinux
553 (fd.o #100912, Laurent Bigonville)
555 • Switch a test from the deprecated g_test_trap_fork() to
556 g_test_trap_subprocess(), for Windows support and better robustness
557 on Unix (fd.o #101362, Simon McVittie)
559 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
560 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
561 This prevents the two files from going out of sync on stateless or live
562 images without needing to run dbus-uuidgen, and supports older D-Bus
563 implementations that do not necessarily read /etc/machine-id themselves.
564 (fd.o #101570, Simon McVittie)
566 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
567 abstract sockets. This is preferable when used with Linux containers.
568 (fd.o #101567, Simon McVittie)
572 • Fix a reference leak when blocking on a pending call on a connection
573 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
575 • Don't put timestamps in the Doxygen-generated documentation,
576 or hard-code the build directory into builds with embedded tests,
577 for reproducible builds (fd.o #100692, Simon McVittie)
579 • Fix some integration test issues (fd.o #100686, Simon McVittie)
581 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
583 • If we somehow get an autolaunch address with multiple semicolon-separated
584 components, and they don't work, don't invalidly "pile up" errors
585 (fd.o #101257, Simon McVittie)
589 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
590 (fd.o #100715, Simon McVittie)
592 D-Bus 1.11.12 (2017-04-07)
595 The “it's something humans do” release.
599 • The session dbus-daemon now supports transient .service files
600 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
601 service directories, this directory is not monitored with inotify
602 or similar, and the service files must be named exactly
603 ${bus_name}.service. (fd.o #99825, Simon McVittie)
605 • dbus can be configured with --enable-relocation when building with
606 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
607 to make the pkg-config metadata relocatable. This is useful for
608 non-standard prefixes, and in particular for Windows installations.
609 However, it is not recommended for system-wide installations into
610 /usr, because it interferes with pkg-config's ability to filter out
611 compiler default linker directories.
613 With Autotools, the default is --enable-relocation when building
614 for Windows or --disable-relocation otherwise. With CMake, the default
615 is -DDBUS_RELOCATABLE=ON.
617 (fd.o #99721; Ralf Habacker, Simon McVittie)
619 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
620 own FindDBus.cmake macros, whether dbus was compiled with Autotools
621 or with CMake. See the end of README.cmake for more information.
622 (fd.o #99721; Ralf Habacker, Simon McVittie)
626 • Always read service file directories in the intended order
627 (fd.o #99825, Simon McVittie)
629 • When tests are skipped, don't try to kill nonexistent process 0
630 (fd.o #99825, Simon McVittie)
632 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
634 • Fix a harmless read overflow and some memory leaks in a unit test
635 (fd.o #100568, Philip Withnall)
637 • Fix some typos in test code
638 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
640 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
641 in documentation (fd.o #99901, Philip Withnall)
643 • Fix and enable compiler warnings related to -Wswitch
644 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
646 • Fix writing off the end of a fd_set when testing with valgrind
647 (fd.o #99839, Philip Withnall)
649 D-Bus 1.11.10 (2017-02-16)
652 The “purple hair gives you telekinesis?” release.
656 • AppArmor support requires at least libapparmor 2.8.95, reduced
657 from 2.10 in previous versions. One test requires 2.10 and is
658 skipped if building with an older version.
662 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
663 stable and Debian testing in addition to the older Ubuntu that is
664 the default (fd.o #98889, Simon McVittie)
666 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
668 • Silence many -Wswitch-enum and -Wswitch-default warnings
669 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
671 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
672 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
674 • Install pkg-config metadata on Unix even if building with CMake
675 (fd.o #99752, Ralf Habacker)
677 • Exclude auth mechanisms from REJECTED message if they are supported
678 in the code but but configured to be disallowed (fd.o #99621,
683 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
684 allow an attacker to overwrite a file named "nonce", in a directory
685 that the user running dbus-daemon can write, with a random value
686 known only to the user running dbus-daemon. This is unlikely to be
687 exploitable in practice, particularly since the nonce-tcp transport
688 is really only useful on Windows.
690 On Unix systems we strongly recommend using only the unix: and systemd:
691 transports, together with EXTERNAL authentication. These are the only
692 transports and authentication mechanisms enabled by default.
694 (fd.o #99828, Simon McVittie)
696 • Avoid symlink attacks in the "embedded tests", which are not enabled
697 by default and should never be enabled in production builds of dbus.
698 (fd.o #99828, Simon McVittie)
700 • Fix the implementation of re-enabling a timeout so that its
701 countdown is restarted as intended, instead of continually
702 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
704 • When receiving a message with file descriptors, do not start reading
705 the beginning of the next message, so that only one such message
706 is processed at a time. In conjunction with the fix for #95619
707 this means that processes sending many file descriptors, such as
708 systemd-logind on a system that receives very rapid ssh connections,
709 are not treated as abusive and kicked off the bus. Revert the previous
710 workaround that special-cased uid 0.
711 (fd.o #95263, LP#1591411; Simon McVittie)
713 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
714 for Windows with CMake (fd.o #99586, Ralf Habacker)
716 • Do not set Unix-specific variables when targeting Windows
717 (fd.o #99586, Ralf Habacker)
719 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
720 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
722 • Use relative install locations in CMake on Unix to respect DESTDIR,
723 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
725 • Install dbus-arch-deps.h correctly when using CMake
726 (fd.o #99586, #99721; Ralf Habacker)
728 • Improve argument validation for `dbus-test-tool spam`
729 (ffd.o #99693, Coverity #54759; Philip Withnall)
731 • Don't shift by a negative integer if a hash table becomes monstrously
732 large (fd.o #99641, Coverity #54682; Philip Withnall)
734 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
735 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
737 • Remove an unnecessary NULL check
738 (fd.o #99642, Coverity #141062; Philip Withnall)
740 • Improve error handling in unit tests and dbus-send
741 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
742 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,
743 #54710, #54711, #54714, #54715, #54718, #54721, #54724, #54726,
744 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
746 • Do not print verbose messages' timestamps to stderr if the actual message
747 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
749 D-Bus 1.11.8 (2016-11-28)
752 The “panics in the face of breakfast foods” release.
754 Build-time configuration:
756 • The new --enable-debug configure option provides an easy way to
757 enable debug symbols, disable optimization and/or enable profiling.
759 • The --enable-compile-warnings configure option can be used to control
762 • The --disable-compiler-optimisations configure option is no longer
763 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
767 • D-Bus Specification version 0.30
768 · Define the jargon term "activation" more clearly
769 · Define the jargon term "auto-starting", which is one form of activation
770 · Document the optional SystemdService key in service files
771 · Use versioned interface and bus names in most examples
772 · Clarify intended behaviour of Properties.GetAll
773 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
775 • Fix and enable a lot of compiler warnings to improve future code
776 quality. This might incidentally also fix some environment variable
778 · In particular, printf-style functions in the libdbus API are now annotated
779 with __attribute__((__format__(__printf__, *, *))) when compiling with
780 gcc or clang. This might make printf bugs in other software visible
782 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
783 Thomas Zimmermann, Simon McVittie)
785 • When running with AppArmor mediation (for example using Ubuntu's patched
786 Linux kernel), clients can no longer auto-start services unless they would
787 have been able to send the auto-starting message to the service after it
788 starts. StartServiceByName() is unaffected, and continues to be allowed by
789 default in AppArmor's <abstractions/dbus-strict> and
790 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
794 • Work around an undesired effect of the fix for CVE-2014-3637
795 (fd.o #80559), in which processes that frequently send fds, such as
796 logind during a flood of new PAM sessions, can get disconnected for
797 continuously having at least one fd "in flight" for too long;
798 dbus-daemon interprets that as a potential denial of service attack.
799 The workaround is to disable that check for uid 0 process such as
800 logind, with a message in the system log. The bug remains open while
801 we look for a more general solution.
802 (fd.o #95263, LP#1591411; Simon McVittie)
804 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
805 was disabled at compile time. That test is not expected to work
806 in that configuration. (fd.o #98665, Simon McVittie)
808 D-Bus 1.11.6 (2016-10-10)
811 The “darkly whimsical” release.
815 • Do not treat ActivationFailure message received from root-owned systemd
816 name as a format string. In principle this is a security vulnerability,
817 but we do not believe it is exploitable in practice, because only
818 privileged processes can own the org.freedesktop.systemd1 bus name, and
819 systemd does not appear to send activation failures that contain "%".
821 Please note that this probably *was* exploitable in dbus versions
822 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
823 the time was only thought to be a denial of service vulnerability
824 (CVE-2015-0245). If you are still running one of those versions,
825 patch or upgrade immediately.
827 (fd.o #98157, Simon McVittie)
831 • D-Bus Specification version 0.29
832 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
833 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
835 • Log to syslog when we exceed various anti-DoS limits, and add test
836 coverage for them (fd.o #86442, Simon McVittie)
838 • Improve syslog handling so that _dbus_warn() and similar warnings
839 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
840 and log to syslog (instead of /dev/null) when dbus-daemon is started by
841 dbus-launch. (fd.o #97009, Simon McVittie)
843 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
844 (fd.o #89011, Philip Withnall)
846 • When logging messages about service activation, mention which peer
847 requested the activation (fd.o #68212, Philip Withnall)
849 • On Linux, mention the LSM label (if available) whenever we print
850 debug information about a peer (fd.o #68212, Philip Withnall)
854 • Harden dbus-daemon against malicious or incorrect ActivationFailure
855 messages by rejecting them if they do not come from a privileged
856 process, or if systemd activation is not enabled
857 (fd.o #98157, Simon McVittie)
859 • Avoid undefined behaviour when setting reply serial number without going
860 via union DBusBasicValue (fd.o #98035, Marc Mutz)
862 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
863 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
865 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
867 D-Bus 1.11.4 (2016-08-15)
870 The “copper pickaxe” release.
874 • Building from git (but not from tarballs) now requires
875 macros from the GNU Autoconf Archive, for example the autoconf-archive
876 package in Debian or Fedora derivatives.
878 Build-time configuration:
880 • The option to enable coverage instrumentation has changed from
881 --enable-compiler-coverage to --enable-code-coverage.
885 • D-Bus Specification version 0.28
886 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
888 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
889 minimizing failed connections under heavy load
890 (fd.o #95264, Lennart Poettering)
892 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
894 • Use the same regression tests for subprocess starting on Unix and Windows
895 (fd.o #95191, Ralf Habacker)
897 • Print timestamps and thread IDs in verbose messages
898 (fd.o #95191, Ralf Habacker)
900 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
901 pointing to /dev/null (fd.o #97008, Simon McVittie)
903 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
904 (fd.o #88922, Thomas Zimmermann)
908 • On Windows, fix a memory leak in replacing the installation prefix
909 (fd.o #95191, Ralf Habacker)
911 • On Linux, when dbus-daemon is run with reduced susceptibility to the
912 OOM killer (typically via systemd), do not let child processes inherit
913 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
915 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
916 even if a parent process incorrectly starts them with stdin, stdout
917 and/or stderr closed (fd.o #97008, Simon McVittie)
919 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
920 contains a semicolon (fd.o #94746, Thiago Macieira)
922 • Fix memory leaks and thread safety in subprocess starting on Windows
923 (fd.o #95191, Ralf Habacker)
925 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
926 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
928 • In tests that exercise correct handling of crashing D-Bus services,
929 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
931 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
933 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
934 in some test cases (fd.o #93909, Nick Lewycky)
936 • Add assertions to reassure a static analysis tool
937 (fd.o #93210, Deepika Aggarwal)
939 • Be explicit about enum comparison when loading XML
940 (fd.o #93205, Deepika Aggarwal)
942 • update-activation-environment: produce better diagnostics on error
943 (fd.o #96653, Simon McVittie)
945 • Avoid various compiler warnings with gcc 6
946 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
948 • On Unix when configured to use the system log, report as "dbus-daemon",
949 not as "dbus" (fd.o #97009, Simon McVittie)
951 • During unit tests, reduce the amount we write to the system log
952 (fd.o #97009, Simon McVittie)
954 D-Bus 1.11.2 (2016-03-07)
957 The “pneumatic drill vs. Iron Maiden” release.
961 • Enable "large file support" on systems where it exists: dbus-daemon
962 is not expected to open large files, but it might need to stat files
963 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
965 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
966 which might result in a pedantic C compiler not copying the entire contents
967 of a DBusMessageIter; statically assert that this is not an ABI change
968 in practice (fd.o #94136, Simon McVittie)
970 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
971 (fd.o #94244, Dmitri Iouchtchenko)
973 • Correctly report test failures in C tests from run-test.sh
974 (fd.o #93379; amit tewari, Simon McVittie)
976 • When tests are enabled, run all the marshal-validate tests, not just
977 the even-numbered ones (fd.o #93908, Nick Lewycky)
979 • Correct the expected error from one marshal-validate test, which was
980 previously not run due to the above bug (fd.o #93908, Simon McVittie)
982 • Fix compilation under CMake when embedded tests are disabled
983 (fd.o #94094, eric.hyer)
987 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
988 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
990 • When building with CMake, use the same gcc/clang warnings as under Autotools,
991 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
993 • test/name-test: make C tests produce TAP output and run them directly, not
994 via run-test.sh (fd.o #92899, Simon McVittie)
996 • Under CMake when cross-compiling for Windows on Unix, run the tests
997 under Wine even if binfmt_misc support is not available
998 (fd.o #88966, Ralf Habacker)
1000 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
1001 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
1003 • Factor out some functions that will be needed in future for a Windows
1004 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
1006 D-Bus 1.11.0 (2015-12-02)
1009 The “peppermint deer” release.
1013 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
1014 C99 constants such as PRId64 and PRIu64.
1018 • D-Bus Specification version 0.27
1019 · Specify that services should not reply if NO_REPLY_EXPECTED was used
1020 (fd.o #75749, Lars Uebernickel)
1022 • Add a script to do continuous-integration builds, and metadata to run it
1023 on travis-ci.org. To use this, clone the dbus git repository on GitHub
1024 and set it up with travis-ci.org; the only special setting needed is
1025 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
1027 • If dbus-daemon is run with --systemd-activation, do not require
1028 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
1032 • Re-order dbus-daemon startup so that on SELinux systems, the thread
1033 that reads AVC notifications retains the ability to write to the
1034 audit log (fd.o #92832, Laurent Bigonville)
1036 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
1038 • When using the Monitoring interface, match messages' destinations
1039 (fd.o #92074, Simon McVittie)
1041 • On Linux with systemd, stop installing a reference to the obsolete
1042 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
1045 • On Windows, when including configuration files with <include> or
1046 <includedir>, apply the same relocation as for the Exec paths
1047 in .service files (fd.o #92028, Simon McVittie)
1049 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
1051 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
1053 D-Bus 1.10.6 (2015-12-01)
1056 The “marzipan beetles” release.
1060 • On Unix when running tests as root, don't assert that root and
1061 the dbus-daemon user can still call UpdateActivationEnvironment;
1062 assert that those privileged users can call BecomeMonitor instead
1063 (fd.o #93036, Simon McVittie)
1065 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
1068 • On Windows Autotools builds, don't run tests that rely on
1069 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
1071 D-Bus 1.10.4 (2015-11-17)
1074 The “Frostburn Canyon” release.
1078 • GetConnectionCredentials, GetConnectionUnixUser and
1079 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
1080 will now return details of the dbus-daemon itself. This is required
1081 to be able to call SetEnvironment on systemd.
1082 (fd.o #92857, Jan Alexander Steffens)
1086 • Make UpdateActivationEnvironment always fail with AccessDenied on the
1087 system bus. Previously, it was possible to configure it so root could
1088 call it, but the environment variables were not actually used,
1089 because the launch helper would discard them.
1090 (fd.o #92857, Jan Alexander Steffens)
1092 • On Unix with --systemd-activation on a user bus, make
1093 UpdateActivationEnvironment pass on its arguments to systemd's
1094 SetEnvironment method, solving inconsistency between the environments
1095 used for traditional activation and systemd user-service activation.
1096 (fd.o #92857, Jan Alexander Steffens)
1098 • On Windows, don't crash if <syslog/> or --syslog is used
1099 (fd.o #92538, Ralf Habacker)
1101 • On Windows, fix a memory leak when setting a DBusError from a Windows
1102 error (fd.o #92721, Ralf Habacker)
1104 • On Windows, don't go into infinite recursion if we abort the process
1105 with backtraces enabled (fd.o #92721, Ralf Habacker)
1107 • Fix various failing tests, variously on Windows and cross-platform:
1108 · don't test system.conf features (users, groups) that only make sense
1109 on the system bus, which is not supported on Windows
1110 · don't call _dbus_warn() when we skip a test, since it is fatal
1111 · fix computation of expected <standard_session_servicedirs/>
1112 · when running TAP tests, translate newlines to Unix format, fixing
1113 cross-compiled tests under Wine on Linux
1114 · don't stress-test refcounting under Wine, where it's really slow
1115 · stop assuming that a message looped-back to the test will be received
1117 · skip some system bus tests on Windows since they make no sense there
1118 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
1120 D-Bus 1.10.2 (2015-10-26)
1123 The “worst pies in London” release.
1127 • Correct error handling for activation: if there are multiple attempts
1128 to activate the same service and it fails immediately, the first attempt
1129 would get the correct reply, but the rest would time out. We now send
1130 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
1132 • If BecomeMonitor is called with a syntactically invalid match rule,
1133 don't crash with an assertion failure, fixing a regression in 1.9.10.
1134 This was not exploitable as a denial of service, because the check
1135 for a privileged user is done first. (fd.o #92298, Simon McVittie)
1137 • On Linux with --enable-user-session, add the bus address to the
1138 environment of systemd services for better backwards compatibility
1139 (fd.o #92612, Jan Alexander Steffens)
1141 • On Windows, fix the logic for replacing the installation prefix
1142 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
1144 • On Windows, if installed in the conventional layout with ${prefix}/etc
1145 and ${prefix}/share, use relative paths between bus configuration files
1146 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
1148 • Make more of the regression tests pass in Windows builds (fd.o #92538,
1151 D-Bus 1.10.0 (2015-08-25)
1156 This is a new stable branch, recommended for use in OS distributions.
1160 • distribute test/tap-test.sh.in, even if the tarball was built without
1161 tests enabled (fd.o #91684, Simon McVittie)
1162 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
1164 Summary of major changes since 1.8.0:
1166 • The basic setup for the well-known system and session buses is
1167 now done in read-only files in ${datadir} (normally /usr/share).
1168 See the NEWS entry for 1.9.18 for details.
1170 • AppArmor integration has been merged, with features similar to the
1171 pre-existing SELinux integration. It is mostly compatible with the
1172 patches previously shipped by Ubuntu, with one significant change:
1173 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
1174 by GetConnectionCredentials and was not included.
1176 • The --enable-user-session configure option can be enabled
1177 by OS integrators intending to use systemd to provide a session bus
1178 per user (in effect, treating all concurrent graphical and non-graphical
1179 login sessions as one large session).
1181 • The new listenable address mode "unix:runtime=yes" listens on
1182 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
1183 user session. libdbus and "dbus-launch --autolaunch" will connect to
1184 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
1187 • All executables are now dynamically linked to libdbus-1.
1188 Previously, some executables, most notably dbus-daemon, were statically
1189 linked to a specially-compiled variant of libdbus. This results in
1190 various private functions in the _dbus namespace being exposed by the
1191 shared library. These are not API, and must not be used outside
1192 the dbus source tree.
1194 • On platforms with ELF symbol versioning, all public symbols
1195 are versioned LIBDBUS_1_3.
1199 • org.freedesktop.DBus.GetConnectionCredentials returns
1200 LinuxSecurityLabel where supported
1201 • org.freedesktop.DBus.Monitoring interface (privileged)
1202 · BecomeMonitor method supersedes match rules with eavesdrop=true,
1203 which are now deprecated
1204 • org.freedesktop.DBus.Stats interface (semi-privileged)
1205 · now enabled by default
1206 · new GetAllMatchRules method
1207 • org.freedesktop.DBus.Verbose interface (not normally compiled)
1208 · toggles the effect of DBUS_VERBOSE
1213 • dbus-update-activation-environment
1215 New optional dependencies:
1217 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
1218 • Complete documentation requires Ducktype and yelp-tools
1219 • Full test coverage requires GLib 2.36 and PyGI
1220 • AppArmor integration requires libapparmor and optionally libaudit
1222 Dependencies removed:
1226 D-Bus 1.9.20 (2015-08-06)
1229 The “Remember Tomorrow” release.
1231 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
1236 • Don't second-guess what the ABI of poll() is, allowing it to be used
1237 on Integrity RTOS and other unusual platforms (fd.o #90314;
1238 Rolland Dudemaine, Simon McVittie)
1240 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
1241 both enabled (fd.o #89225, Simon McVittie)
1243 • Log audit events for AppArmor/SELinux policy violations whenever
1244 we have CAP_AUDIT_WRITE, even if not the system bus
1245 (fd.o #83856, Laurent Bigonville)
1247 D-Bus 1.9.18 (2015-07-21)
1250 The “Pirate Elite” release.
1252 Configuration changes:
1254 • The basic setup for the well-known system and session buses is now done
1255 in read-only files in ${datadir}, moving a step closer to systems
1256 that can operate with an empty /etc directory. In increasing order
1259 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
1260 the default message policies.
1261 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
1262 dbus still installs a trivial version of each, for documentation
1263 purposes; putting configuration directives in these files is deprecated.
1264 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
1265 to install "drop-in" configuration snippets (any packages
1266 using those directories should explicitly depend on at least this
1268 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
1269 or third-party software to install "drop-in" configuration snippets
1270 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
1273 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
1274 and "s*" refers to either system or session as appropriate.
1276 (fd.o #89280, Dimitri John Ledkov)
1280 • Fix a memory leak when GetConnectionCredentials() succeeds
1281 (fd.o #91008, Jacek Bukarewicz)
1283 • Ensure that dbus-monitor does not reply to messages intended for others,
1284 resulting in its own disconnection (fd.o #90952, Simon McVittie)
1286 D-Bus 1.9.16 (2015-05-14)
1289 The “titanium barns” release.
1293 • Automake 1.13 is now required when compiling from git or modifying
1298 • On Unix platforms, change the default configuration for the session bus
1299 to only allow EXTERNAL authentication (secure kernel-mediated
1300 credentials-passing), as was already done for the system bus.
1302 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
1303 unpredictable pseudo-random numbers.
1305 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
1306 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1307 NFS or similar, you will need to reconfigure the session bus to accept
1308 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1311 (fd.o #90414, Simon McVittie)
1313 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1314 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1315 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1316 occurs, instead of silently falling back to low-entropy pseudorandom
1317 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1321 • Add dbus_message_iter_get_element_count()
1322 (fd.o #30350; Christian Dywan, Simon McVittie)
1324 • Introduce new internal DBusSocket and DBusPollable types so we can
1325 stop treating the Windows SOCKET type as if it was int. DBusSocket
1326 is specifically a socket, cross-platform. DBusPollable is whatever
1327 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1328 (fd.o #89444; Ralf Habacker, Simon McVittie)
1330 • All regression tests now output TAP <https://testanything.org/>
1331 (fd.o #89846, Simon McVittie)
1333 • Internal APIs consistently use signed values for timestamps
1334 (fd.o #18494, Peter McCurdy)
1336 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1337 (fd.o #88812, Simon McVittie)
1339 • Clean up a lot of compiler warnings
1340 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1344 • Add locking to DBusCounter's reference count and notify function
1345 (fd.o #89297, Adrian Szyndela)
1347 • Ensure that DBusTransport's reference count is protected by the
1348 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1350 • Correctly release DBusServer mutex before early-return if we run out
1351 of memory while copying authentication mechanisms (fd.o #90021,
1354 • Make dbus-test-tool and dbus-update-activation-environment portable
1355 to Windows (fd.o #90089, Ralf Habacker)
1357 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1358 Ralf Habacker, Simon McVittie)
1360 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1363 • Clean up some memory and fd leaks in test code and tools
1364 (fd.o #90021, Ralf Habacker)
1366 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1367 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1369 • CMake generates a versioned shared library even if the revision is 0,
1370 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1372 D-Bus 1.9.14 (2015-03-02)
1375 The “don't stand in the poison cloud” release.
1379 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1380 were previously linked to a static version of libdbus.
1382 • The tests no longer require dbus-glib in order to exercise the libdbus
1383 shared library; they are always linked to libdbus now.
1385 Build-time configuration:
1387 • The new --enable-user-session option, off by default, can be enabled
1388 by OS integrators intending to use systemd to provide a session bus
1389 per user (in effect, treating all concurrent graphical and non-graphical
1390 login sessions as one large session)
1394 • All executables are now linked dynamically to libdbus.
1395 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1397 • On platforms that support them (GNU libc and possibly others),
1398 libdbus now has versioned symbols for its public API.
1399 All public symbols (visible in the header files) are currently
1400 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1401 dbus_internal have a version that changes with each release, and
1402 must not be used by applications. (also fd.o #83115)
1404 • New listenable address mode "unix:runtime=yes" which listens on
1405 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1406 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1408 • Add optional systemd units for a per-user bus listening on
1409 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1411 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1412 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1415 • New dbus-update-activation-environment tool uploads environment
1416 variables to "dbus-daemon --session" and optionally "systemd --user",
1417 primarily as a way to keep the per-user bus compatible with
1418 distributions' existing X11 login scripts (also fd.o #61301)
1420 • <includedir/> elements in dbus-daemon configuration are now silently
1421 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1423 • Add microsecond-resolution timestamps to the default output of
1424 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1428 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1429 (fd.o #89222, Simon McVittie)
1431 D-Bus 1.9.12 (2015-02-19)
1434 The “monster lasagna” release.
1438 • Ducktype and yelp-tools are now required to build complete documentation
1439 (they are optional for normal builds).
1443 • D-Bus Specification version 0.26
1444 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1445 · document the BecomeMonitor method
1447 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1448 (fd.o #89041; Tyler Hicks, Simon McVittie)
1450 • On Linux, add support for AppArmor mediation of message sending and
1451 receiving and name ownership (paralleling existing SELinux mediation
1452 support), and eavesdropping (a new check, currently AppArmor-specific)
1453 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1455 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1456 that have printable ASCII contents; we previously only did this for
1457 unterminated bytestrings (fd.o #89109, Simon McVittie)
1459 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1461 • On Windows, add WindowsSID to GetConnectionCredentials
1462 (fd.o #54445, Ralf Habacker)
1464 • Improve clarity of dbus-monitor --profile output and add more columns
1465 (fd.o #89165, Ralf Habacker)
1467 • Add a man page for dbus-test-tool, and build it under CMake as well
1468 as Autotools (fd.o#89086, Simon McVittie)
1470 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1471 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1472 (fd.o #88896, Ralf Habacker)
1476 • Reduce the number of file descriptors used in the fd-passing test,
1477 avoiding failure under the default Linux fd limit, and automatically
1478 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1480 D-Bus 1.9.10 (2015-02-09)
1483 The “sad cyborgs” release.
1485 Security fixes merged from 1.8.16:
1487 • Do not allow non-uid-0 processes to send forged ActivationFailure
1488 messages. On Linux systems with systemd activation, this would
1489 allow a local denial of service: unprivileged processes could
1490 flood the bus with these forged messages, winning the race with
1491 the actual service activation and causing an error reply
1492 to be sent back when service auto-activation was requested.
1493 This does not prevent the real service from being started,
1494 so the attack only works while the real service is not running.
1495 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1499 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1500 similar tools receive messages without altering the security properties
1501 of the system bus, by calling the new BecomeMonitor method on a
1502 private connection. This bypasses the normal <allow> and <deny> rules
1503 entirely, so to preserve normal message-privacy assumptions, only root
1504 is allowed to do this on the system bus. Restricted environments,
1505 such as Linux with LSMs, should lock down access to the Monitoring
1506 interface. (fd.o #46787, Simon McVittie)
1508 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1509 dbus-daemon supports it and access permissions allow it.
1510 It still supports the previous approach ("eavesdropping" match rules)
1511 for compatibility with older bus daemons. (fd.o #46787, Simon)
1513 • dbus-monitor can now log the message stream as binary data for later
1514 analysis, with either no extra framing beyond the normal D-Bus headers,
1515 or libpcap-compatible framing treating each D-Bus message
1516 as a captured packet. (fd.o #46787, Simon)
1520 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1522 • On Unix, forcibly terminate regression tests after 60 seconds to
1523 prevent them from blocking continuous integration frameworks
1524 (fd.o #46787, Simon)
1526 D-Bus 1.9.8 (2015-02-03)
1529 The “all the types of precipitation” release.
1533 • full test coverage now requires GLib 2.36
1534 • full test coverage now requires PyGI (PyGObject 3,
1535 "import gi.repository.GObject") instead of the
1536 obsolete PyGObject 2 ("import gobject")
1540 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1542 • better regression test coverage, including systemd activation
1543 (fd.o #57952, #88810; Simon McVittie)
1547 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1548 turned off (fd.o #88808, Simon McVittie)
1550 • TCP sockets on Windows no longer fail to listen approximately 1 time
1551 in 256, caused by a logic error that should have always made it fail but
1552 was mitigated by incorrect endianness for the port number
1553 (fd.o #87999, Ralf Habacker)
1555 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1557 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1558 previous 64, completing a previous fix which only worked under
1559 Autotools (fd.o #71297, Ralf Habacker)
1561 • on Windows, if the IP family is unspecified only use IPv4,
1562 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1564 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1566 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1568 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1571 D-Bus 1.9.6 (2015-01-05)
1574 The “I do have a bread knife” release.
1578 • Do not allow calls to UpdateActivationEnvironment from uids other than
1579 the uid of the dbus-daemon. If a system service installs unsafe
1580 security policy rules that allow arbitrary method calls
1581 (such as CVE-2014-8148) then this prevents memory consumption and
1582 possible privilege escalation via UpdateActivationEnvironment.
1584 We believe that in practice, privilege escalation here is avoided
1585 by dbus-daemon-launch-helper sanitizing its environment; but
1586 it seems better to be safe.
1588 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1589 on object paths other than /org/freedesktop/DBus. Some system services
1590 install unsafe security policy rules that allow arbitrary method calls
1591 to any destination, method and interface with a specified object path;
1592 while less bad than allowing arbitrary method calls, these security
1593 policies are still harmful, since dbus-daemon normally offers the
1594 same API on all object paths and other system services might behave
1599 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1600 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1602 D-Bus 1.9.4 (2014-11-24)
1605 The “extra-sturdy caramel” release.
1609 • Partially revert the CVE-2014-3639 patch by increasing the default
1610 authentication timeout on the system bus from 5 seconds back to 30
1611 seconds, since this has been reported to cause boot regressions for
1612 some users, mostly with parallel boot (systemd) on slower hardware.
1614 On fast systems where local users are considered particularly hostile,
1615 administrators can return to the 5 second timeout (or any other value
1616 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1619 <limit name="auth_timeout">5000</limit>
1622 (fd.o #86431, Simon McVittie)
1624 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1625 (fd.o #86431, Simon McVittie)
1627 • Send back an AccessDenied error if the addressed recipient is not allowed
1628 to receive a message (and in builds with assertions enabled, don't
1629 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1631 D-Bus 1.9.2 (2014-11-10)
1634 The “structurally unsound flapjack” release.
1638 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1639 so that CVE-2014-3636 part A cannot exhaust the system bus'
1640 file descriptors, completing the incomplete fix in 1.8.8.
1641 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1645 • D-Bus Specification version 0.25
1646 · new value 'const' for EmitsChangedSignal annotation
1647 (fd.o #72958, Lennart Poettering)
1648 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1649 (fd.o #83449; Lennart Poettering, Simon McVittie)
1650 · annotate table of types with reserved/basic/container, and for
1651 basic types, fixed/string-like
1652 · clarify arbitrary limits by quoting them in mebibytes
1654 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1655 (fd.o #83449, Simon McVittie)
1657 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1658 useful for debugging and performance testing:
1659 · dbus-test-tool spam: send repeated messages
1660 · dbus-test-tool echo: send an empty reply for all method calls
1661 · dbus-test-tool black-hole: do not reply to method calls
1662 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1664 • Add support for process ID in credentials-passing on NetBSD
1665 (fd.o #69702, Patrick Welche)
1667 • Add an example script to find potentially undesired match rules
1668 (fd.o #84598, Alban Crequy)
1670 • Document the central assumption that makes our use of credentials-passing
1671 secure (fd.o #83499, Simon McVittie)
1673 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1674 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1679 • Use a less confusing NoReply message when disconnected with a reply pending
1680 (fd.o #76112, Simon McVittie)
1682 • Make the .pc file relocatable by letting pkg-config do all variable
1683 expansion itself (fd.o #75858, Руслан Ижбулатов)
1685 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1686 (fd.o #85563, Patrick Welche)
1688 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1690 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1691 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1693 • Do not fail the tests if a parent process has leaked non-close-on-exec
1694 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1696 • Do not fail the tests on Unix platforms with incomplete
1697 credentials-passing support, but do fail if we can't pass credentials
1698 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1699 (fd.o #69702, Simon McVittie)
1701 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1702 when building with cmake, and expand test coverage there
1703 (fd.o #73689; Ralf Habacker, Simon McVittie)
1705 D-Bus 1.9.0 (2014-10-01)
1708 The “tiered cheeses” release.
1712 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1713 requires either the libsystemd or libsd-daemon shared library, dropping the
1714 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1716 Build-time configuration changes:
1718 • The Stats interface is now enabled by default, and locked-down to
1719 root-only on the system bus. Configure with --disable-stats
1720 to disable it altogether on memory- or disk-constrained systems,
1721 or see ${docdir}/examples/ to open it up to non-root users on the
1722 system bus or restrict access on the session bus.
1723 (fd.o #80759; Simon McVittie, Alban Crequy)
1725 • The CMake build system now builds the same shared library name as Autotools
1726 on at least Linux and Windows:

1728 libdbus-1.so, but now builds libdbus-1.so.3.* with development

1730 - on Windows, it previously built either libdbus-1.dll (release) or
1731 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1732 libdbus-1.dll for compatibility with older applications.

1800 could lead to a 4-byte heap buffer overrun.
1801 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1803 • Reduce default for maximum Unix file descriptors passed per message
1804 from 1024 to 16, preventing a uid with the default maximum number of
1805 connections from exhausting the system bus' file descriptors under
1806 Linux's default rlimit. Distributors or system administrators with a
1807 more restrictive fd limit may wish to reduce these limits further.

1912 D-Bus 1.8.0 (2014-01-20)
1915 The “Wolverine distrusts my printer” release.
1917 This starts a new stable branch. The 1.6.x branch is now considered to be
1918 outdated, and will only receive fixes for serious bugs such as security
1919 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1920 are unlikely to get any more releases, but if distributors still need to
1921 support them, please share security patches via upstream.
1923 Summary of changes since 1.6.x:
1925 • libdbus always behaves as if dbus_threads_init_default() had been called
1926 (thread-safety by default)
1927 • new dbus-run-session tool, replacing certain misuses of dbus-launch
1928 • dbus-monitor can talk to outdated versions of dbus-daemon again
1929 • new org.freedesktop.DBus.GetConnectionCredentials method
1930 • GetConnectionUnixProcessID also works correctly on Windows, returning
1931 the Windows process ID
1932 • GetConnectionWindowsSID returns the correct SID on Windows
1933 • expat is required, libxml2 can no longer be used as a substitute
1934 • the userDB cache is required, and cannot be disabled
1935 • a 64-bit integer type (either int, long, long long or _int64) is required
1936 • better systemd-journald integration on Linux
1937 • fixed long-standing fd and array leaks when failing to parse a message
1938 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
1939 when using certain object-path allocation patterns, notably in Avahi
1940 • better defaults for Windows support
1941 • better CMake support
1942 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
1943 • the source language for the man pages is now Docbook XML
1945 Enhancements since 1.7.10:
1947 • Enhance the CMake build system to check for GLib and compile/run
1948 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
1952 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
1955 • fix compilation of systemd journal support on older systemd versions where
1956 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
1958 • fix compilation on older MSVC versions by including stdlib.h
1959 (fd.o #73455, Ralf Habacker)
1961 • Allow <allow_anonymous/> to appear in an included configuration file
1962 (fd.o #73475, Matt Hoosier)
1964 Test behaviour changes since 1.7.10:
1966 • If the tests crash with an assertion failure, they no longer default to
1967 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
1968 environment if you want the old behaviour.
1970 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
1971 can be run with an external dbus-daemon by setting
1972 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
1973 an unusually-configured dbus-daemon are skipped.
1975 D-Bus 1.7.10 (2014-01-06)
1978 The “weighted companion cube” release.
1980 This is a release candidate for D-Bus 1.8.
1982 D-Bus Specification 0.23:
1984 • don't require messages with no INTERFACE to be dispatched
1985 (fd.o #68597, Simon McVittie)
1987 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
1990 • define "listenable" and "connectable" addresses, and discuss
1991 the difference (fd.o #61303, Simon McVittie)
1995 • support printing Unix file descriptors in dbus-send, dbus-monitor
1996 (fd.o #70592, Robert Ancell)
1998 • don't install systemd units if --disable-systemd is given
1999 (fd.o #71818, Chengwei Yang)
2003 • don't leak memory on out-of-memory while listing activatable or
2004 active services (fd.o #71526, Radoslaw Pajak)
2006 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
2008 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
2010 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
2011 and DBUS__SEND_MSG are numerically equal to their values in the
2012 reference policy (fd.o #88719, osmond sun)
2014 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
2015 (fd.o #71366, Matt Fischer)
2017 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
2018 winsock2.h (fd.o #71405, Matt Fischer)
2020 • do not return failure from _dbus_read_nonce() with no error set,
2021 preventing a potential crash (fd.o #72298, Chengwei Yang)
2023 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
2024 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
2026 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
2027 which doesn't do anything anyway on at least Linux and FreeBSD
2028 (fd.o #69492, Simon McVittie)
2030 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
2031 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
2032 for credentials more correctly (fd.o #69492, Simon McVittie)
2034 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
2035 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
2038 • refresh cached policy rules for existing connections when bus
2039 configuration changes (fd.o #39463, Chengwei Yang)
2041 D-Bus 1.7.8 (2013-11-01)
2044 The “extreme hills” release.
2048 • If systemd support is enabled, libsystemd-journal is now required.
2052 • When activating a non-systemd service under systemd, annotate its
2053 stdout/stderr with its bus name in the Journal. Known limitation:
2054 because the socket is opened before forking, the process will still be
2055 logged as if it had dbus-daemon's process ID and user ID.
2056 (fd.o #68559, Chengwei Yang)
2058 • Document more configuration elements in dbus-daemon(1)
2059 (fd.o #69125, Chengwei Yang)
2063 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
2064 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
2066 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
2067 disallowed method calls to the audit log, fixing a regression in 1.7.6
2068 (fd.o #49062, Colin Walters)
2070 • path_namespace='/' in match rules incorrectly matched nothing; it
2071 now matches everything. (fd.o #70799, Simon McVittie)
2073 D-Bus 1.7.6 (2013-10-09)
2076 The “CSI Shrewsbury” release.
2078 Build-time configuration changes:
2080 • Directory change notification via dnotify on Linux is no longer
2081 supported; it hadn't compiled successfully since 2010 in any case.
2082 If you don't have inotify (Linux) or kqueue (*BSD), you will need
2083 to send SIGHUP to the dbus-daemon when its configuration changes.
2084 (fd.o #33001, Chengwei Yang)
2086 • Compiling with --disable-userdb-cache is no longer supported;
2087 it didn't work since at least 2008, and would lead to an extremely
2088 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
2091 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
2092 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
2093 with the Autotools build system. (fd.o #66142, Chengwei Yang)
2095 • --with-valgrind=auto enables Valgrind instrumentation if and only if
2096 valgrind headers are available. The default is still --with-valgrind=no.
2097 (fd.o #56925, Simon McVittie)
2101 • Platforms with no 64-bit integer type are no longer supported.
2102 (fd.o #65429, Simon McVittie)
2104 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
2106 • Full test coverage no longer requires dbus-glib, although the tests do not
2107 exercise the shared library (only a static copy) if dbus-glib is missing.
2108 (fd.o #68852, Simon McVittie)
2112 • D-Bus Specification 0.22
2113 · Document GetAdtAuditSessionData() and
2114 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
2115 · Fix example .service file (fd.o #66481, Chengwei Yang)
2116 · Don't claim D-Bus is "low-latency" (lower than what?), just
2117 give factual statements about it supporting async use
2118 (fd.o #65141, Justin Lee)
2119 · Document the contents of .service files, and the fact that
2120 system services' filenames are constrained
2121 (fd.o #66608; Simon McVittie, Chengwei Yang)
2123 • Be thread-safe by default on all platforms, even if
2124 dbus_threads_init_default() has not been called. For compatibility with
2125 older libdbus, library users should continue to call
2126 dbus_threads_init_default(): it is harmless to do so.
2127 (fd.o #54972, Simon McVittie)
2129 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
2131 • New API: dbus_setenv(), a simple wrapper around setenv().
2132 Note that this is not thread-safe. (fd.o #39196, Simon)
2134 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
2135 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
2136 (connect to a given bus, like dbus-monitor --address=ADDRESS).
2137 dbus-send --address still exists for backwards compatibility,
2138 but is no longer documented. (fd.o #48816, Andrey Mazo)
2141 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
2146 • Avoid an infinite busy-loop if a signal interrupts waitpid()
2147 (fd.o #68945, Simon McVittie)
2149 • Clean up memory for parent nodes when objects are unexported
2150 (fd.o #60176, Thomas Fitzsimmons)
2152 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
2153 documented. Previously, it assumed its second parameter was TRUE.
2154 (fd.o #69165, Chengwei Yang)
2156 • Escape addresses containing non-ASCII characters correctly
2157 (fd.o #53499, Chengwei Yang)
2159 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
2161 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
2162 (fd.o #65923, Chengwei Yang)
2164 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
2165 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
2167 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
2168 that was never va_start()ed (fd.o #66300, Chengwei Yang)
2170 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
2172 • fix a regression test on platforms with strict alignment (fd.o #67279,
2175 • Avoid calling function parameters "interface" since certain Windows headers
2176 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
2178 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
2180 • Various thread-safety improvements to static variables (fd.o #68610,
2183 • Make "make -j check" work (fd.o #68852, Simon McVittie)
2185 • Fix a NULL pointer dereference on an unlikely error path
2186 (fd.o #69327, Sviatoslav Chagaev)
2188 • Improve valgrind memory pool tracking (fd.o #69326,
2191 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
2194 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
2195 (fd.o #66107, Chengwei Yang)
2198 · If accept4() fails with EINVAL, as it can on older Linux kernels
2199 with newer glibc, try accept() instead of going into a busy-loop.
2200 (fd.o #69026, Chengwei Yang)
2201 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
2202 for instance on Hurd or older Linux with a new glibc, try without
2203 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)

2205 (fd.o #69182, Sviatoslav Chagaev)
2206 · dbus-run-session: clear some unwanted environment variables
2207 (fd.o #39196, Simon)
2208 · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang)
2209 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
2210 · Use dbus-launch from the builddir for testing, not the installed copy
2211 (fd.o #37849, Chengwei Yang)
2212 · Fix compilation if writev() is unavailable (fd.o #69409,
2214 · Remove broken support for LOCAL_CREDS credentials passing, and
2215 document where each credential-passing scheme is used (fd.o #60340,
2217 · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality
2218 (fd.o #35881, #69787; Chengwei Yang)
2219 · dbus-monitor: be portable to NetBSD (fd.o #69842, Chengwei Yang)

2243 D-Bus 1.7.4 (2013-06-13)
2246 The “but is your thread-safety thread-safe?” release.
2250 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
2251 of service for system services. Vulnerability reported by Alexandru Cornea.
2256 • The Windows version of libdbus now contains a C++ source file, used
2257 to provide global initialization when the library is loaded.
2258 gcc (mingw*) users should ensure that g++ is also installed.
2260 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
2261 and was never the recommended option) has been removed. Expat is now a
2266 • It should now be safe to call dbus_threads_init_default() from any thread,
2267 at any time. Authors of loadable modules and plugins that use libdbus
2268 should consider doing so during initialization.

2271 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
2275 · dbus-run-session: experimental new tool to start a temporary D-Bus
2276 session, e.g. for regression tests or a text console, replacing
2277 certain uses of dbus-launch which weren't really correct

2282 • In dbus-daemon, don't crash if a .service file starts with key=value
2283 (fd.o #60853, Chengwei Yang)
2286 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
2287 on a platform not defining LOG_PERROR, such as Solaris or QNX.
2288 This regressed in 1.7.0. (Simon)
2289 · Fix an assertion failure if we try to activate systemd services before
2290 systemd connects to the bus (fd.o #50199, Chengwei Yang)
2291 · Avoid compiler warnings for ignoring the return from write()
2295 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/

2298 D-Bus 1.7.2 (2013-04-25)
2301 The “only partially opaque” release.
2303 Configuration changes:
2305 • On non-QNX Unix platforms, the default limit on fds per message in the
2306 session bus configuration has reduced from 4096 to 1024. The default
2307 limit used on the system bus was already 1024. On QNX, both limits are
2308 reduced further, to 128.
2312 • D-Bus Specification 0.21
2313 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,

2347 D-Bus 1.7.0 (2013-02-22)
2350 The "Disingenuous Assertions" release.
2352 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
2353 remains the recommended version for long-term-supported distributions
2354 or the upcoming GNOME 3.8 release.
2356 Build-time configuration changes:
2358 • The --with-dbus-session-bus-default-address configure option is no longer
2359 supported. Use the new --with-dbus-session-bus-connect-address and
2360 --with-dbus-session-bus-listen-address options instead. On Windows, you
2361 usually want them to have the same argument; on Unix, the defaults are
2364 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2365 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2366 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2368 • cmake/cross-compile.sh has been removed. Instead, please use a
2369 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2370 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2371 as documented in "info automake Cross-Compilation", and set
2372 PKG_CONFIG_PATH appropriately.
2376 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
2377 • man2html is no longer used.
2381 • D-Bus Specification 0.20
2382 · actually say that /org/freedesktop/DBus is the object that
2383 implements o.fd.DBus (fd.o #51865, Colin Walters)
2384 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
2385 · stop claiming that all basic types work just like INT32 (strings don't!)
2387 • The "source code" for the man pages is now Docbook XML, eliminating
2388 the outdated duplicate copies used when building with CMake.
2389 (fd.o #59805; Ralf Habacker, Simon McVittie)
2393 • In the activation helper, when compiled for tests, do not reset the system
2394 bus address, fixing the regression tests. (fd.o #52202, Simon)
2396 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
2397 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
2399 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

2414 (at least) OpenBSD (fd.o #47239, Simon)
2415 · Don't leak temporary fds pointing to /dev/null (fd.o #56927,
2417 · Update sd-daemon.[ch] from systemd (fd.o #60681)
2418 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
2421 · The default session bus listening and connecting address is now
2422 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2423 and GDBus "out of the box". Use the configure options and cmake variables
2424 described above if you require a different autolaunch scope.
2425 (fd.o #38201, Simon McVittie)
2426 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
2428 • Create session.d, system.d directories under CMake (fd.o #41319,
2431 D-Bus 1.6.8 (2012-09-28)
2434 The "Fix one thing, break another" release.
2436 • Follow up to CVE-2012-3524: The additional hardening
2437 work to use __secure_getenv() as a followup to bug #52202
2438 broke certain configurations of gnome-keyring. Given
2439 the difficulty of making this work without extensive
2440 changes to gnome-keyring, use of __secure_getenv() is

2482 (fd.o #51032, Simon McVittie)
2484 • Disconnect "developer mode" (assertions, verbose mode etc.) from
2485 Automake maintainer mode. D-Bus developers should now configure with
2486 --enable-developer. Automake maintainer mode is now on by default;
2487 distributions can disable it with --disable-maintainer-mode.
2488 (fd.o #34671, Simon McVittie)
2490 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
2491 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
2494 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
2496 D-Bus 1.6.0 (2012-06-05)
2499 The “soul of this machine has improved” release.
2501 This version starts a new stable branch of D-Bus: only bug fixes will
2502 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
2504 Summary of changes since 1.4.x:
2507 · PTHREAD_MUTEX_RECURSIVE on Unix

2543 Changes since 1.5.12:
2545 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
2546 spec-compliance (fd.o #48580, David Zeuthen)
2548 • Don't use install(1) within the source/build trees, fixing the build as
2549 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
2551 • Add missing commas in some tcp and nonce-tcp addresses, and remove
2552 an unused duplicate copy of the nonce-tcp transport in Windows builds
2553 (fd.o #45896, Simon McVittie)
2555 D-Bus 1.5.12 (2012-03-27)
2558 The “Big Book of Science” release.
2560 • Add public API to validate various string types:
2561 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
2562 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
2563 (fd.o #39549, Simon McVittie)
2565 • Turn DBusBasicValue into public API so bindings don't need to invent their
2566 own "union of everything" type (fd.o #11191, Simon McVittie)
2568 • Enumerate data files included in the build rather than using find(1)
2569 (fd.o #33840, Simon McVittie)

2578 (fd.o #47321, Andoni Morales Alastruey)
2580 D-Bus 1.5.10 (2012-02-21)
2583 The "fire in Delerium" release.
2585 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2586 and SUSv2) is now required.
2588 • D-Bus Specification 0.19:
2589 · Formally define unique connection names and well-known bus names,
2590 and document best practices for interface, bus, member and error names,
2591 and object paths (fd.o #37095, Simon McVittie)
2592 · Document the search path for session and system services on Unix, and
2593 where they should be installed by build systems (fd.o #21620, fd.o #35306;
2595 · Document the systemd transport (fd.o #35232, Lennart Poettering)
2597 • Make dbus_threads_init() use the same built-in threading implementation
2598 as dbus_threads_init_default(); the user-specified primitives that it
2599 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
2601 • Allow all configured auth mechanisms, not just one (fd.o #45106,
2604 • Improve cmake build system (Ralf Habacker):
2605 · simplify XML parser dependencies (fd.o #41027)
2606 · generate build timestamp (fd.o #41029)
2607 · only create batch files on Windows
2608 · fix option and cache syntax
2609 · add help-options target
2610 · share dbus-arch-deps.h.in with autotools rather than having our
2611 own version (fd.o #41033)
2613 • Build tests successfully with older GLib, as found in e.g. Debian 6
2614 (fd.o #41219, Simon McVittie)
2616 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
2618 • Build documentation correctly if man2html doesn't support filenames on
2619 its command-line (fd.o #43875, Jack Nagel)
2621 • Improve test coverage. To get even more coverage, run the tests with
2622 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
2624 • Reduce the size of the shared library by moving functionality only used
2625 by dbus-daemon, tests etc. into their internal library and deleting
2626 unused code (fd.o #34976, #39759; Simon McVittie)
2628 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2629 setups where the default configuration must include <pidfile/> to avoid
2630 breaking traditional init, but the pid file is in fact unnecessary; use
2631 it under systemd to improve startup time a bit (fd.o #45520,
2634 • Optionally (if configured --with-valgrind) add instrumentation to debug
2635 libdbus and associated tools more meaningfully under Valgrind
2636 (fd.o #37286, Simon McVittie)
2638 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
2640 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
2642 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
2643 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
2644 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
2647 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
2651 · Replace our broken reimplementation of recursive mutexes, which has
2652 been broken since 2006, with an ordinary pthreads recursive mutex
2653 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2654 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2655 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2656 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2657 · When running under systemd, use it instead of ConsoleKit to check
2658 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2659 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2660 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2661 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2662 (fd.o #41218, Simon McVittie)
2663 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2664 helper doesn't obey environment variables to avoid privilege escalation
2665 attacks, so make the system bus follow the same rules
2666 (fd.o #21620, Simon McVittie)
2669 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2670 Jesper Dam, Ralf Habacker)
2671 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
2674 D-Bus 1.5.8 (2011-09-21)
2677 The "cross-metering" release.
2679 In addition to dead code removal and refactoring, this release contains all
2680 of the bugfixes from 1.4.16.
2682 • Clean up dead code, and make more warnings fatal in development builds
2683 (fd.o #39231, fd.o #41012; Simon McVittie)
2685 • If full test coverage is requested via --enable-tests, strictly require
2686 Python, pygobject and dbus-python, which are required by some tests; if not,
2687 and Python is missing, skip those tests rather than failing
2688 (fd.o #37847, Simon McVittie)
2690 • When using cmake, provide the same version-info API in the installed headers
2691 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2693 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
2695 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
2697 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
2700 • Fix duplicates in authors list (Ralf Habacker)
2702 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2703 (fd.o #39879, Chris Mayo)
2705 • Fix a small memory leak, and a failure to report errors, when updating
2706 a service file entry for activation (fd.o #39230, Simon McVittie)
2709 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2710 Brian Cameron, Simon McVittie)
2711 · On systems that use libcap-ng but not systemd, drop supplemental groups
2712 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2713 · Make the cmake build work again on GNU platforms (fd.o #29228,
2715 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
2716 like Solaris (fd.o #40313, Dagobert Michelsen)
2717 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2718 (fd.o #40235, Simon McVittie)
2719 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2720 (fd.o #39987, Simon McVittie)
2721 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2722 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2725 · Fix compilation on MSVC, which doesn't understand "inline" with its
2726 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2727 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2728 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2730 D-Bus 1.5.6 (2011-07-29)
2733 The "weird, gravy-like aftertaste" release.
2735 In addition to new features and refactoring, this release contains all of the
2736 bugfixes from 1.4.14.
2738 Potentially incompatible (Bustle and similar debugging tools will need
2739 changes to work as intended):
2741 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2742 different recipient) by mistake: eavesdroppers must now opt-in to this
2743 behaviour by putting "eavesdrop='true'" in the match rule, which will
2744 not have any practical effect on buses where eavesdropping is not allowed
2745 (fd.o #37890, Cosimo Alfarano)
2749 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2750 Cosimo Alfarano, Simon McVittie)
2751 · add the "eavesdrop" keyword to match rules
2752 · define eavesdropping, unicast messages and broadcast messages
2753 · stop claiming that match rules are needed to match unicast messages to you
2754 · promote the type system to be a top-level section
2756 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2757 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2758 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2760 • Consistently use atomic operations on everything that is ever manipulated
2761 via atomic ops, as was done for changes to DBusConnection's refcount in
2762 1.4.12 (fd.o #38005, Simon McVittie)
2764 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2767 • Make "make check" in a clean tree work, by not running tests until
2768 test data has been set up (fd.o #34405, Simon McVittie)
2770 • The dbus-daemon no longer busy-loops if it has a very large number of file
2771 descriptors (fd.o #23194, Simon McVittie)
2773 • Refactor message flow through dispatching to avoid locking violations if
2774 the bus daemon's message limit is hit; remove the per-connection link cache,
2775 which was meant to improve performance, but now reduces it (fd.o #34393,
2778 • Some cmake fixes (Ralf Habacker)
2780 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2781 Simon McVittie, Lennart Poettering)
2783 • Stop storing two extra byte order indicators in each D-Bus message
2784 (fd.o #38287, Simon McVittie)
2786 • Add an optional Stats interface which can be used to get statistics from
2787 a running dbus-daemon if enabled at configure time with --enable-stats
2788 (fd.o #34040, Simon McVittie)
2790 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2792 • Documentation (fd.o #36156, Simon McVittie):
2793 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2794 · install more documentation automatically, including man2html output
2795 · put dbus.devhelp in the right place (it must go in ${htmldir})
2798 · look for system services in /lib/dbus-1/system-services in addition to all
2799 the other well-known locations; note that this should always be /lib,
2800 even on platforms where shared libraries on the root FS would go in /lib64,
2801 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2802 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2804 • Windows-specific (Ralf Habacker):
2805 · fix use of a mutex for autolaunch server detection
2806 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2808 D-Bus 1.5.4 (2011-06-10)
2811 Security (local denial of service):
2813 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2814 local DoS if foreign-endian messages are relayed through the dbus-daemon
2815 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2816 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2820 • The constant to use for an infinite timeout now has a name,
2821 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2822 which can be used for source compatibility with older versions of libdbus.
2824 • If GLib and DBus-GLib are already installed, more tests will be built,
2825 providing better coverage. The new tests can also be installed via
2826 ./configure --enable-installed-tests
2827 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2831 • Consistently use atomic operations for the DBusConnection's refcount,
2832 fixing potential threading problems (fd.o #38005, Simon McVittie)
2834 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2835 small (300KiB on x86-64) and it frequently doesn't work in unusual
2836 toolchains. To optimize for minimum installed size, you should benchmark
2837 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2838 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2840 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2841 (fd.o #35880, Timothy Redaelli)
2843 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2844 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2846 • Windows-specific changes:
2847 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2849 D-Bus 1.5.2 (2011-06-01)
2852 The "Boar Hunter" release.
2854 Notes for distributors:
2856 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2857 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2858 toolchain supports it reliably, via something like:
2860 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2862 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2866 • D-Bus Specification v0.17

2871 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2872 • Allow --disable-gc-sections, in case your toolchain offers the
2873 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2874 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2875 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2876 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)

2887 (fd.o #35228, Lennart Poettering)
2888 • In the regression tests, don't report fds as "leaked" if they were open
2889 on startup (fd.o #35173, Simon McVittie)

2909 · Make argNpath support object paths, not just object-path-like strings,
2910 and document it better (fd.o #31818, Will Thompson)
2911 • Let the bus daemon implement more than one interface (fd.o #33757,
2913 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2915 • Require user intervention to compile with missing 64-bit support
2916 (fd.o #35114, Simon McVittie)
2917 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
2918 • Raise UnknownObject instead of UnknownMethod for calls to methods on

2928 (fd.o #32245; Javier Jardón, Simon McVittie)
2929 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
2931 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
2932 --disable-x11-autolaunch configure option to prevent it altogether
2933 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
2934 • Install the documentation, and an index for Devhelp (fd.o #13495,
2935 Debian #454142; Simon McVittie, Matthias Clasen)
2936 • If checks are not disabled, check validity of string-like types and
2937 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
2938 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
2939 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
2940 • Break up a huge conditional in config-parser so gcov can produce coverage
2941 data (fd.o #10887, Simon McVittie)
2942 • List which parts of the Desktop Entry specification are applicable to
2943 .service files (fd.o #19159, Sven Herzberg)
2944 • Don't suppress service activation if two services have the same Exec=

2958 which were mistakenly included in 1.4.4
2960 D-Bus 1.4.4 (2010-02-17)
2963 • Switch back to using even micro versions for stable releases; 1.4.1
2964 should have been called 1.4.2, so skip that version number
2965 • Don't leave bad file descriptors being watched when spawning processes,
2966 which could result in a busy-loop (fd.o #32992, NB#200248; possibly

3001 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
3002 crash the bus. The existing restriction to 64-levels of nesting previously
3003 only applied to the static type signature; now it also applies to dynamic
3004 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
