1 dbus 1.12.2 (UNRELEASED)
2 ========================
8 • Log a warning if a new connection cannot be accepted due to an
9 out-of-memory condition or failure to identify its AppArmor or
10 SELinux context (fd.o #103592, Simon McVittie)
14 • Make use of $(MKDIR_P) compatible with install-sh, fixing build when a
15 GNU-compatible `mkdir -p` is not available (fd.o #103521, ilovezfs)
17 • When building for Windows with Autotools, avoid `echo -e`, fixing
18 cross-compilation on non-GNU platforms like macOS
19 (fd.o #103493, Tony Theodore)
21 • Fix crashes in the server side of the nonce-tcp: transport under
22 various error conditions. This transport should normally only be used
23 on Windows, where AF_UNIX sockets are unavailable; the unix: transport
24 is the only one recommended for production use on Unix platforms.
25 (fd.o #103597, Simon McVittie)
29 • Improve test coverage on Travis-CI (Simon McVittie)
31 dbus 1.12.0 (2017-10-30)
32 ========================
34 The “gingerbread skull” release.
36 1.12.x is a new stable branch, recommended for use in OS
39 Summary of major changes between 1.10.x and 1.12.0
40 --------------------------------------------------
44 • Expat >= 2.1.0 is required.
45 • GLib >= 2.40 is required if full test coverage is enabled.
46 • [Linux] libselinux >= 2.0.86 is required if SELinux support is
48 • [Unix] dbus now requires an <inttypes.h> that defines C99 constants
49 such as PRId64 and PRIu64, except when building for Windows.
50 • [Autotools] Building from git (but not from tarballs) with Autotools
51 now requires macros from the GNU Autoconf Archive.
52 • [CMake] Builds done using CMake now require CMake 3.0.2.
54 Build-time configuration changes:
56 • Expat is now found using pkg-config. See the release notes for
58 • The --disable-compiler-optimisations and --enable-compiler-coverage
59 options no longer exist. See the release notes for 1.11.4 and 1.11.8.
60 • [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
61 options no longer exist. See the release notes for 1.11.20.
62 • [Unix] Flag files in /var/run/console/${username} are no longer
63 checked for at_console by default. See the release notes for 1.11.18.
64 • [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
65 and packagers will now need to add these downstream (most already do).
66 See the release notes for 1.11.18.
67 • [Unix] The process ID file no longer has a different default location
68 on Red Hat derivatives. See the release notes for 1.11.18.
69 • [Unix] ${runstatedir} is now independent of ${localstatedir} with
70 recent Autotools versions. See the release notes for 1.11.16.
71 • [Windows] The WINDRES variable is no longer used. See the release
76 • Eavesdropping is officially deprecated in favour of BecomeMonitor.
77 See the release notes for spec version 0.31 (in dbus 1.11.14).
78 • [Unix] Flag files in /var/run/console/${username} are deprecated.
79 See the release notes for 1.11.18.
83 • <allow> and <deny> rules in dbus-daemon configuration can now
84 include send_broadcast="true", send_broadcast="false",
85 max_unix_fds="N", min_unix_fds="N" (for some integer N).
86 See the release notes for 1.11.18.
87 • dbus_try_get_local_machine_id() is like
88 dbus_get_local_machine_id(), but returns a DBusError.
89 • New APIs around DBusMessageIter to simplify cleanup.
90 See the release notes for 1.11.16.
91 • The message bus daemon now implements the standard Introspectable,
92 Peer and Properties interfaces. See the release notes for
93 dbus 1.11.14 and spec version 0.31.
94 • DTDs for introspection XML and bus configuration are installed.
95 • dbus can be compiled to be relocatable, making it more suitable for
96 binary bundling with other software. On Windows, this is on by
98 • [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
99 never uses Linux abstract sockets, which is advantageous for
100 containers. On non-Linux it is equivalent to unix:tmpdir=….
101 See the release notes for dbus 1.11.14 and spec version 0.31.
102 • [Unix] New option "dbus-launch --exit-with-x11".
103 • [Unix] Session managers can create transient .service files in
104 $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
105 • [Unix] A sysusers.d snippet can create the messagebus user on-demand.
107 Miscellaneous behaviour changes:
109 • [Unix] The session bus now logs to syslog if it was started by
111 • [Unix] Internal warnings are logged to syslog if configured.
112 • [Unix] Exceeding an anti-DoS limit is logged to syslog if configured,
115 Changes since 1.11.22 release candidate
116 ---------------------------------------
118 Standard stable-branch changes:
120 • Disable warnings about use of deprecated functions (Simon McVittie)
124 • Don't distribute files generated by ./configure in the source tarball
125 (fd.o #103420, Simon McVittie)
129 • Remove some unused files from the git repository
130 (fd.o #103420, Simon McVittie)
132 D-Bus 1.11.22 (2017-10-23)
133 ==========================
135 The “fire surface” release.
137 This is the first release-candidate for the 1.12.0 stable release.
139 Build-time configuration changes:
141 • When building for Windows with Autotools, setting the WINDRES variable
142 no longer works to select a non-standard resource compiler. Use
143 libtool's standard RC variable instead, for example
144 "./configure RC=i686-w64-mingw32-windres"
148 • Builds done using CMake now require CMake 3.0.2.
152 • When building for Windows, improve quality of metadata in
153 libdbus-1-3.dll (fd.o #103015, Ralf Habacker)
157 • Fix a typo "uint 16" in dbus-send(1) man page
158 (fd.o #103075, David King)
160 • When building for Windows, libdbus-1-3.dll always includes version
161 information. Previously, this was missing if using CMake and any
162 non-MSVC compiler. (fd.o #103015, Ralf Habacker)
164 • Fix the build with MSVC, which regressed with the #102558 fix in
165 1.11.20. (fd.o #102558, Ralf Habacker)
169 • Simplify Windows resource embedding
170 (fd.o #103015, Simon McVittie)
172 D-Bus 1.11.20 (2017-10-03)
175 The “wraith stun” release.
177 Build-time configuration changes:
179 • The --enable-abstract-sockets and --disable-abstract-sockets options
180 no longer exist. Support for Linux's abstract AF_UNIX sockets is now
181 unconditionally enabled on Linux and disabled everywhere else.
182 (fd.o #34905, Simon McVittie)
186 • Make slower tests less likely to time out, and improve diagnostics if
187 tests do time out (fd.o #103009, Simon McVittie)
189 • On Windows, don't compile an unused stub implementation of
190 _dbus_set_signal_handler() (fd.o #103010, Simon McVittie)
194 • Be more careful to save and restore errno in POSIX async signal
195 handlers (fd.o #103010, Simon McVittie)
197 • On Windows, embed a manifest in dbus-update-activation-environment.exe
198 so that the heuristics used for UAC do not assume it needs elevated
199 privileges due to its name containing "update"
200 (fd.o #102558, Ralf Habacker)
202 • On Windows with Automake, embed version information in libdbus-1,
203 as was meant to happen in all versions since 2009
204 (fd.o #103015, Simon McVittie)
206 D-Bus 1.11.18 (2017-09-25)
209 The “vampire conquistador” release.
211 Build-time configuration changes:
213 • By default, dbus-daemon on Unix no longer checks for flag files
214 /var/run/console/${username} created by the obsolete pam_console and
215 pam_foreground PAM modules when deciding whether ${username} is
216 currently at the console. The old default behaviour can be restored
217 by specifying --with-console-auth-dir=/var/run/console in the
218 recommended Autotools build system, or
219 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
220 now deprecated, and will be removed in dbus 1.13 unless feedback via
221 fd.o #101629 indicates that this would be problematic.
222 (fd.o #101629, Simon McVittie)
224 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
225 script for Cygwin, are no longer provided in the upstream dbus
226 source. We recommend that distributors who support non-systemd service
227 management should maintain their own init scripts or other service
228 manager integration as part of their downstream packaging, similar to
229 the way Debian distributes a Debian-specific LSB init script for dbus.
231 The systemd unit continues to be maintained as part of the upstream
232 dbus source, because it receives regular testing and maintenance.
234 (fd.o #101706, Simon McVittie)
236 • The process ID file created by the system bus is no longer influenced
237 by the --with-init-scripts=redhat configure option or the presence of
238 /etc/redhat-release at build time. If your OS's init script or other
239 service management relies on the Red Hat-style pid file, it can be
240 restored by specifying --with-system-pid-file=/run/messagebus.pid at
241 configure time or using the <pidfile> directive in bus configuration.
243 Note that the upstream-supplied systemd unit runs dbus-daemon with
244 the --nopidfile option, so it does not normally write a pid file,
245 regardless of whether the OS is Red-Hat-derived or not.
247 (fd.o #101706, Simon McVittie)
251 • <allow> and <deny> rules in dbus-daemon configuration can now
252 include send_broadcast="true" or send_broadcast="false", which make
253 the rule only match broadcast signals, or only match messages that
254 are not broadcast signals, respectively.
255 (fd.o #29853, Simon McVittie)
257 • <allow> and <deny> rules can now be configured to apply only to
258 messages with or without Unix file descriptors attached. This would
259 typically be used in rules like these:
260 <allow send_destination="..." max_unix_fds="0"/>
261 <deny send_destination="..." min_unix_fds="1"/>
262 <deny receive_sender="..." min_unix_fds="1"/>
263 but can also be used to set a nonzero upper limit on the number of
265 <allow send_destination="..." max_unix_fds="4"/>
266 (fd.o #101848, Simon McVittie)
268 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
269 now respects the HOME environment variable on the client side, and
270 on the server side when the uid attempting to connect is the same
271 as the uid of the server. This allows the automated tests to pass in
272 environments where the user's "official" home directory in /etc/passwd
273 is nonexistent, such as Debian autobuilders.
274 (fd.o #101960, Simon McVittie)
278 • When parsing dbus-daemon configuration, tell Expat not to use
279 cryptographic-quality entropy as a salt for its hash tables: we trust
280 the configuration files, so we are not concerned about algorithmic
281 complexity attacks via hash table collisions. This prevents
282 dbus-daemon --system from holding up the boot process (and causing
283 early-boot system services like systemd, logind, networkd to time
284 out) on entropy-starved embedded systems.
285 (fd.o #101858, Simon McVittie)
287 • Avoid a -Werror=declaration-after-statement build failure on Solaris
288 (fd.o #102145, Alan Coopersmith)
290 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
291 to LOG_INFO, matching how we use this log level in practice
292 (fd.o #102686, Simon McVittie)
294 D-Bus 1.11.16 (2017-07-27)
297 The “south facing garden” release.
299 Build-time configuration changes:
301 • The Autotools build system now supports varying ${runstatedir}
302 independently of ${localstatedir}, if using an Autoconf version
303 that has that feature; version 2.70 will eventually have this, but
304 many Linux distributions add it to version 2.69 as a patch.
305 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
306 and runstatedir=/run. (fd.o #101569, Simon McVittie)
310 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
311 and dbus_message_iter_abandon_container_if_open() simplify the
312 single-exit-point ("goto out") style of resource cleanup. The API
313 documentation around DBusMessageIter and containers has also been
314 clarified. (fd.o #101568, Simon McVittie)
318 • Fix the implementation of re-enabling a timeout (again) so that its
319 countdown is always restarted as intended. (fd.o #95619,
322 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
323 available to all users on the system bus (fd.o #101700, Simon McVittie)
325 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
326 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
328 • dbus_message_iter_open_container() no longer leaks memory if it runs out
329 of memory. (fd.o #101568, Simon McVittie)
331 • dbus_message_append_args_valist() no longer leaks memory if given an
332 unsupported type. This situation is still considered to be a programming
333 error which needs to be corrected by the user of libdbus.
334 (fd.o #101568, Simon McVittie)
336 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
337 will no longer report that their arguments were invalid if they run out
338 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
340 • Ensure that tests fail if they would otherwise have tried to connect to
341 the real session bus (fd.o #101698, Simon McVittie)
343 • Make build-time tests cope with finding Python 3, but not Python 2
344 (fd.o #101716, Simon McVittie)
346 Internal changes relevant to dbus developers:
348 • DBusVariant is a new mechanism to copy single values from a message into
349 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
351 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
352 Logging an ERROR message does not make the process exit; the caller
353 is responsible for calling abort() or exit(), whichever is more appropriate.
354 (fd.o #101568, Simon McVittie)
356 • Better test coverage (fd.o #101568, Simon McVittie)
358 D-Bus 1.11.14 (2017-06-29)
361 The “irrational fear of bees” release.
365 • Expat >= 2.1.0 is always required
366 • libselinux >= 2.0.86 is required if SELinux support is enabled
367 • GLib >= 2.40 is required if full test coverage is enabled
369 Build-time configuration changes:
371 • We now use pkg-config to find libexpat in Autotools builds. This requires
372 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
373 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
374 itself cause compilation failures.
376 As with all pkg-config-based configure checks, you can use
377 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
378 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
379 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
382 (fd.o #69801, Simon McVittie)
384 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
385 is required due to the removal of explicit refcounting for SIDs.
386 (fd.o #100912, Laurent Bigonville)
390 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
391 as a side-effect of a sufficiently privileged process merely reading the
392 machine ID. It is no longer copied as a side-effect of reading.
393 Running dbus-uuidgen --ensure, which should be done after installing dbus,
394 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
395 former exists and the latter does not.
396 (fd.o #101257, Simon McVittie)
398 • The undocumented Verbose interface, and the GetAllMatchRules method on
399 the undocumented Stats interface, must now be used via the object path
400 /org/freedesktop/DBus. Previously, they existed on all object paths.
401 (fd.o #101257, Simon McVittie)
403 • AddMatch() with a match rule containing eavesdrop='true' will now fail
404 unless called by either the same user as the dbus-daemon, or Unix uid 0
405 (root), matching the restrictions applied to the newer BecomeMonitor()
406 method. On the session bus this has no practical effect. On the system
407 bus this will prevent certain configurations that already did not
408 work well in practice. (fd.o #101567, Simon McVittie)
412 • D-Bus Specification version 0.31
413 · Don't require implementation-specific search paths to be lowest
415 · Correct regex syntax for optionally-escaped bytes in addresses so it
416 includes hyphen-minus, forward slash and underscore as intended
417 · Describe all message bus methods in the same section
418 · Clarify the correct object path for method calls to the message bus
419 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
420 · Document that the message bus implements Introspectable, Peer and
422 · Add new Features and Interfaces properties for message bus
424 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
426 · Don't require eavesdrop='true' to be accepted from connections not
427 sufficiently privileged to use it successfully
428 · Formally deprecate eavesdropping in favour of BecomeMonitor
429 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
430 Simon McVittie, Tom Gundersen)
432 • Implement the Properties and Peer interfaces in dbus-daemon
433 (fd.o #101257, Simon McVittie)
435 • New function dbus_try_get_local_machine_id() is like
436 dbus_get_local_machine_id(), but returning a DBusError. Other code
437 that needs the machine ID will now report a recoverable error (instead
438 of logging to stderr and aborting) if no machine ID is available.
439 Generating a machine ID is still considered to be a required part of
440 installing dbus correctly. (fd.o #13194, Simon McVittie)
442 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
443 (fd.o #101315, Laurent Bigonville)
445 • Avoid deprecated API calls when using SELinux
446 (fd.o #100912, Laurent Bigonville)
448 • Switch a test from the deprecated g_test_trap_fork() to
449 g_test_trap_subprocess(), for Windows support and better robustness
450 on Unix (fd.o #101362, Simon McVittie)
452 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
453 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
454 This prevents the two files from going out of sync on stateless or live
455 images without needing to run dbus-uuidgen, and supports older D-Bus
456 implementations that do not necessarily read /etc/machine-id themselves.
457 (fd.o #101570, Simon McVittie)
459 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
460 abstract sockets. This is preferable when used with Linux containers.
461 (fd.o #101567, Simon McVittie)
465 • Fix a reference leak when blocking on a pending call on a connection
466 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
468 • Don't put timestamps in the Doxygen-generated documentation,
469 or hard-code the build directory into builds with embedded tests,
470 for reproducible builds (fd.o #100692, Simon McVittie)
472 • Fix some integration test issues (fd.o #100686, Simon McVittie)
474 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
476 • If we somehow get an autolaunch address with multiple semicolon-separated
477 components, and they don't work, don't invalidly "pile up" errors
478 (fd.o #101257, Simon McVittie)
482 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
483 (fd.o #100715, Simon McVittie)
485 D-Bus 1.11.12 (2017-04-07)
488 The “it's something humans do” release.
492 • The session dbus-daemon now supports transient .service files
493 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
494 service directories, this directory is not monitored with inotify
495 or similar, and the service files must be named exactly
496 ${bus_name}.service. (fd.o #99825, Simon McVittie)
498 • dbus can be configured with --enable-relocation when building with
499 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
500 to make the pkg-config metadata relocatable. This is useful for
501 non-standard prefixes, and in particular for Windows installations.
502 However, it is not recommended for system-wide installations into
503 /usr, because it interferes with pkg-config's ability to filter out
504 compiler default linker directories.
506 With Autotools, the default is --enable-relocation when building
507 for Windows or --disable-relocation otherwise. With CMake, the default
508 is -DDBUS_RELOCATABLE=ON.
510 (fd.o #99721; Ralf Habacker, Simon McVittie)
512 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
513 own FindDBus.cmake macros, whether dbus was compiled with Autotools
514 or with CMake. See the end of README.cmake for more information.
515 (fd.o #99721; Ralf Habacker, Simon McVittie)
519 • Always read service file directories in the intended order
520 (fd.o #99825, Simon McVittie)
522 • When tests are skipped, don't try to kill nonexistent process 0
523 (fd.o #99825, Simon McVittie)
525 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
527 • Fix a harmless read overflow and some memory leaks in a unit test
528 (fd.o #100568, Philip Withnall)
530 • Fix some typos in test code
531 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
533 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
534 in documentation (fd.o #99901, Philip Withnall)
536 • Fix and enable compiler warnings related to -Wswitch
537 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
539 • Fix writing off the end of a fd_set when testing with valgrind
540 (fd.o #99839, Philip Withnall)
542 D-Bus 1.11.10 (2017-02-16)
545 The “purple hair gives you telekinesis?” release.
549 • AppArmor support requires at least libapparmor 2.8.95, reduced
550 from 2.10 in previous versions. One test requires 2.10 and is
551 skipped if building with an older version.
555 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
556 stable and Debian testing in addition to the older Ubuntu that is
557 the default (fd.o #98889, Simon McVittie)
559 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
561 • Silence many -Wswitch-enum and -Wswitch-default warnings
562 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
564 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
565 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
567 • Install pkg-config metadata on Unix even if building with CMake
568 (fd.o #99752, Ralf Habacker)
570 • Exclude auth mechanisms from REJECTED message if they are supported
571 in the code but but configured to be disallowed (fd.o #99621,
576 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
577 allow an attacker to overwrite a file named "nonce", in a directory
578 that the user running dbus-daemon can write, with a random value
579 known only to the user running dbus-daemon. This is unlikely to be
580 exploitable in practice, particularly since the nonce-tcp transport
581 is really only useful on Windows.
583 On Unix systems we strongly recommend using only the unix: and systemd:
584 transports, together with EXTERNAL authentication. These are the only
585 transports and authentication mechanisms enabled by default.
587 (fd.o #99828, Simon McVittie)
589 • Avoid symlink attacks in the "embedded tests", which are not enabled
590 by default and should never be enabled in production builds of dbus.
591 (fd.o #99828, Simon McVittie)
593 • Fix the implementation of re-enabling a timeout so that its
594 countdown is restarted as intended, instead of continually
595 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
597 • When receiving a message with file descriptors, do not start reading
598 the beginning of the next message, so that only one such message
599 is processed at a time. In conjunction with the fix for #95619
600 this means that processes sending many file descriptors, such as
601 systemd-logind on a system that receives very rapid ssh connections,
602 are not treated as abusive and kicked off the bus. Revert the previous
603 workaround that special-cased uid 0.
604 (fd.o #95263, LP#1591411; Simon McVittie)
606 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
607 for Windows with CMake (fd.o #99586, Ralf Habacker)
609 • Do not set Unix-specific variables when targeting Windows
610 (fd.o #99586, Ralf Habacker)
612 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
613 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
615 • Use relative install locations in CMake on Unix to respect DESTDIR,
616 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
618 • Install dbus-arch-deps.h correctly when using CMake
619 (fd.o #99586, #99721; Ralf Habacker)
621 • Improve argument validation for `dbus-test-tool spam`
622 (ffd.o #99693, Coverity #54759; Philip Withnall)
624 • Don't shift by a negative integer if a hash table becomes monstrously
625 large (fd.o #99641, Coverity #54682; Philip Withnall)
627 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
628 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
630 • Remove an unnecessary NULL check
631 (fd.o #99642, Coverity #141062; Philip Withnall)
633 • Improve error handling in unit tests and dbus-send
634 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
635 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,

637 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
639 • Do not print verbose messages' timestamps to stderr if the actual message
640 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
642 D-Bus 1.11.8 (2016-11-28)
645 The “panics in the face of breakfast foods” release.
647 Build-time configuration:
649 • The new --enable-debug configure option provides an easy way to
650 enable debug symbols, disable optimization and/or enable profiling.
652 • The --enable-compile-warnings configure option can be used to control
655 • The --disable-compiler-optimisations configure option is no longer
656 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
660 • D-Bus Specification version 0.30
661 · Define the jargon term "activation" more clearly
662 · Define the jargon term "auto-starting", which is one form of activation
663 · Document the optional SystemdService key in service files
664 · Use versioned interface and bus names in most examples
665 · Clarify intended behaviour of Properties.GetAll
666 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
668 • Fix and enable a lot of compiler warnings to improve future code
669 quality. This might incidentally also fix some environment variable
671 · In particular, printf-style functions in the libdbus API are now annotated
672 with __attribute__((__format__(__printf__, *, *))) when compiling with
673 gcc or clang. This might make printf bugs in other software visible
675 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
676 Thomas Zimmermann, Simon McVittie)
678 • When running with AppArmor mediation (for example using Ubuntu's patched
679 Linux kernel), clients can no longer auto-start services unless they would
680 have been able to send the auto-starting message to the service after it
681 starts. StartServiceByName() is unaffected, and continues to be allowed by
682 default in AppArmor's <abstractions/dbus-strict> and
683 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
687 • Work around an undesired effect of the fix for CVE-2014-3637
688 (fd.o #80559), in which processes that frequently send fds, such as
689 logind during a flood of new PAM sessions, can get disconnected for
690 continuously having at least one fd "in flight" for too long;
691 dbus-daemon interprets that as a potential denial of service attack.
692 The workaround is to disable that check for uid 0 process such as
693 logind, with a message in the system log. The bug remains open while
694 we look for a more general solution.
695 (fd.o #95263, LP#1591411; Simon McVittie)
697 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
698 was disabled at compile time. That test is not expected to work
699 in that configuration. (fd.o #98665, Simon McVittie)
701 D-Bus 1.11.6 (2016-10-10)
704 The “darkly whimsical” release.
708 • Do not treat ActivationFailure message received from root-owned systemd
709 name as a format string. In principle this is a security vulnerability,
710 but we do not believe it is exploitable in practice, because only
711 privileged processes can own the org.freedesktop.systemd1 bus name, and
712 systemd does not appear to send activation failures that contain "%".
714 Please note that this probably *was* exploitable in dbus versions
715 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
716 the time was only thought to be a denial of service vulnerability
717 (CVE-2015-0245). If you are still running one of those versions,
718 patch or upgrade immediately.
720 (fd.o #98157, Simon McVittie)
724 • D-Bus Specification version 0.29
725 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
726 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
728 • Log to syslog when we exceed various anti-DoS limits, and add test
729 coverage for them (fd.o #86442, Simon McVittie)
731 • Improve syslog handling so that _dbus_warn() and similar warnings
732 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
733 and log to syslog (instead of /dev/null) when dbus-daemon is started by
734 dbus-launch. (fd.o #97009, Simon McVittie)
736 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
737 (fd.o #89011, Philip Withnall)
739 • When logging messages about service activation, mention which peer
740 requested the activation (fd.o #68212, Philip Withnall)
742 • On Linux, mention the LSM label (if available) whenever we print
743 debug information about a peer (fd.o #68212, Philip Withnall)
747 • Harden dbus-daemon against malicious or incorrect ActivationFailure
748 messages by rejecting them if they do not come from a privileged
749 process, or if systemd activation is not enabled
750 (fd.o #98157, Simon McVittie)
752 • Avoid undefined behaviour when setting reply serial number without going
753 via union DBusBasicValue (fd.o #98035, Marc Mutz)
755 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
756 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
758 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
760 D-Bus 1.11.4 (2016-08-15)
763 The “copper pickaxe” release.
767 • Building from git (but not from tarballs) now requires
768 macros from the GNU Autoconf Archive, for example the autoconf-archive
769 package in Debian or Fedora derivatives.
771 Build-time configuration:
773 • The option to enable coverage instrumentation has changed from
774 --enable-compiler-coverage to --enable-code-coverage.
778 • D-Bus Specification version 0.28
779 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
781 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
782 minimizing failed connections under heavy load
783 (fd.o #95264, Lennart Poettering)
785 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
787 • Use the same regression tests for subprocess starting on Unix and Windows
788 (fd.o #95191, Ralf Habacker)
790 • Print timestamps and thread IDs in verbose messages
791 (fd.o #95191, Ralf Habacker)
793 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
794 pointing to /dev/null (fd.o #97008, Simon McVittie)
796 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
797 (fd.o #88922, Thomas Zimmermann)
801 • On Windows, fix a memory leak in replacing the installation prefix
802 (fd.o #95191, Ralf Habacker)
804 • On Linux, when dbus-daemon is run with reduced susceptibility to the
805 OOM killer (typically via systemd), do not let child processes inherit
806 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
808 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
809 even if a parent process incorrectly starts them with stdin, stdout
810 and/or stderr closed (fd.o #97008, Simon McVittie)
812 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
813 contains a semicolon (fd.o #94746, Thiago Macieira)
815 • Fix memory leaks and thread safety in subprocess starting on Windows
816 (fd.o #95191, Ralf Habacker)
818 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
819 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
821 • In tests that exercise correct handling of crashing D-Bus services,
822 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
824 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
826 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
827 in some test cases (fd.o #93909, Nick Lewycky)
829 • Add assertions to reassure a static analysis tool
830 (fd.o #93210, Deepika Aggarwal)
832 • Be explicit about enum comparison when loading XML
833 (fd.o #93205, Deepika Aggarwal)
835 • update-activation-environment: produce better diagnostics on error
836 (fd.o #96653, Simon McVittie)
838 • Avoid various compiler warnings with gcc 6
839 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
841 • On Unix when configured to use the system log, report as "dbus-daemon",
842 not as "dbus" (fd.o #97009, Simon McVittie)
844 • During unit tests, reduce the amount we write to the system log
845 (fd.o #97009, Simon McVittie)
847 D-Bus 1.11.2 (2016-03-07)
850 The “pneumatic drill vs. Iron Maiden” release.
854 • Enable "large file support" on systems where it exists: dbus-daemon
855 is not expected to open large files, but it might need to stat files
856 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
858 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
859 which might result in a pedantic C compiler not copying the entire contents
860 of a DBusMessageIter; statically assert that this is not an ABI change
861 in practice (fd.o #94136, Simon McVittie)
863 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
864 (fd.o #94244, Dmitri Iouchtchenko)
866 • Correctly report test failures in C tests from run-test.sh
867 (fd.o #93379; amit tewari, Simon McVittie)
869 • When tests are enabled, run all the marshal-validate tests, not just
870 the even-numbered ones (fd.o #93908, Nick Lewycky)
872 • Correct the expected error from one marshal-validate test, which was
873 previously not run due to the above bug (fd.o #93908, Simon McVittie)
875 • Fix compilation under CMake when embedded tests are disabled
876 (fd.o #94094, eric.hyer)
880 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
881 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
883 • When building with CMake, use the same gcc/clang warnings as under Autotools,
884 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
886 • test/name-test: make C tests produce TAP output and run them directly, not
887 via run-test.sh (fd.o #92899, Simon McVittie)
889 • Under CMake when cross-compiling for Windows on Unix, run the tests
890 under Wine even if binfmt_misc support is not available
891 (fd.o #88966, Ralf Habacker)
893 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
894 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
896 • Factor out some functions that will be needed in future for a Windows
897 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
899 D-Bus 1.11.0 (2015-12-02)
902 The “peppermint deer” release.
906 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
907 C99 constants such as PRId64 and PRIu64.
911 • D-Bus Specification version 0.27
912 · Specify that services should not reply if NO_REPLY_EXPECTED was used
913 (fd.o #75749, Lars Uebernickel)
915 • Add a script to do continuous-integration builds, and metadata to run it
916 on travis-ci.org. To use this, clone the dbus git repository on GitHub
917 and set it up with travis-ci.org; the only special setting needed is
918 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
920 • If dbus-daemon is run with --systemd-activation, do not require
921 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
925 • Re-order dbus-daemon startup so that on SELinux systems, the thread
926 that reads AVC notifications retains the ability to write to the
927 audit log (fd.o #92832, Laurent Bigonville)
929 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
931 • When using the Monitoring interface, match messages' destinations
932 (fd.o #92074, Simon McVittie)
934 • On Linux with systemd, stop installing a reference to the obsolete
935 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
938 • On Windows, when including configuration files with <include> or
939 <includedir>, apply the same relocation as for the Exec paths
940 in .service files (fd.o #92028, Simon McVittie)
942 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
944 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
946 D-Bus 1.10.6 (2015-12-01)
949 The “marzipan beetles” release.
953 • On Unix when running tests as root, don't assert that root and
954 the dbus-daemon user can still call UpdateActivationEnvironment;
955 assert that those privileged users can call BecomeMonitor instead
956 (fd.o #93036, Simon McVittie)
958 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
961 • On Windows Autotools builds, don't run tests that rely on
962 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
964 D-Bus 1.10.4 (2015-11-17)
967 The “Frostburn Canyon” release.
971 • GetConnectionCredentials, GetConnectionUnixUser and
972 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
973 will now return details of the dbus-daemon itself. This is required
974 to be able to call SetEnvironment on systemd.
975 (fd.o #92857, Jan Alexander Steffens)
979 • Make UpdateActivationEnvironment always fail with AccessDenied on the
980 system bus. Previously, it was possible to configure it so root could
981 call it, but the environment variables were not actually used,
982 because the launch helper would discard them.
983 (fd.o #92857, Jan Alexander Steffens)
985 • On Unix with --systemd-activation on a user bus, make
986 UpdateActivationEnvironment pass on its arguments to systemd's
987 SetEnvironment method, solving inconsistency between the environments
988 used for traditional activation and systemd user-service activation.
989 (fd.o #92857, Jan Alexander Steffens)
991 • On Windows, don't crash if <syslog/> or --syslog is used
992 (fd.o #92538, Ralf Habacker)
994 • On Windows, fix a memory leak when setting a DBusError from a Windows
995 error (fd.o #92721, Ralf Habacker)
997 • On Windows, don't go into infinite recursion if we abort the process
998 with backtraces enabled (fd.o #92721, Ralf Habacker)
1000 • Fix various failing tests, variously on Windows and cross-platform:
1001 · don't test system.conf features (users, groups) that only make sense
1002 on the system bus, which is not supported on Windows
1003 · don't call _dbus_warn() when we skip a test, since it is fatal
1004 · fix computation of expected <standard_session_servicedirs/>
1005 · when running TAP tests, translate newlines to Unix format, fixing
1006 cross-compiled tests under Wine on Linux
1007 · don't stress-test refcounting under Wine, where it's really slow
1008 · stop assuming that a message looped-back to the test will be received
1010 · skip some system bus tests on Windows since they make no sense there
1011 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
1013 D-Bus 1.10.2 (2015-10-26)
1016 The “worst pies in London” release.
1020 • Correct error handling for activation: if there are multiple attempts
1021 to activate the same service and it fails immediately, the first attempt
1022 would get the correct reply, but the rest would time out. We now send
1023 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
1025 • If BecomeMonitor is called with a syntactically invalid match rule,
1026 don't crash with an assertion failure, fixing a regression in 1.9.10.
1027 This was not exploitable as a denial of service, because the check
1028 for a privileged user is done first. (fd.o #92298, Simon McVittie)
1030 • On Linux with --enable-user-session, add the bus address to the
1031 environment of systemd services for better backwards compatibility
1032 (fd.o #92612, Jan Alexander Steffens)
1034 • On Windows, fix the logic for replacing the installation prefix
1035 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
1037 • On Windows, if installed in the conventional layout with ${prefix}/etc
1038 and ${prefix}/share, use relative paths between bus configuration files
1039 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
1041 • Make more of the regression tests pass in Windows builds (fd.o #92538,
1044 D-Bus 1.10.0 (2015-08-25)
1049 This is a new stable branch, recommended for use in OS distributions.
1053 • distribute test/tap-test.sh.in, even if the tarball was built without
1054 tests enabled (fd.o #91684, Simon McVittie)
1055 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
1057 Summary of major changes since 1.8.0:
1059 • The basic setup for the well-known system and session buses is
1060 now done in read-only files in ${datadir} (normally /usr/share).
1061 See the NEWS entry for 1.9.18 for details.
1063 • AppArmor integration has been merged, with features similar to the
1064 pre-existing SELinux integration. It is mostly compatible with the
1065 patches previously shipped by Ubuntu, with one significant change:
1066 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
1067 by GetConnectionCredentials and was not included.
1069 • The --enable-user-session configure option can be enabled
1070 by OS integrators intending to use systemd to provide a session bus
1071 per user (in effect, treating all concurrent graphical and non-graphical
1072 login sessions as one large session).
1074 • The new listenable address mode "unix:runtime=yes" listens on
1075 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
1076 user session. libdbus and "dbus-launch --autolaunch" will connect to
1077 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
1080 • All executables are now dynamically linked to libdbus-1.
1081 Previously, some executables, most notably dbus-daemon, were statically
1082 linked to a specially-compiled variant of libdbus. This results in
1083 various private functions in the _dbus namespace being exposed by the
1084 shared library. These are not API, and must not be used outside
1085 the dbus source tree.
1087 • On platforms with ELF symbol versioning, all public symbols
1088 are versioned LIBDBUS_1_3.
1092 • org.freedesktop.DBus.GetConnectionCredentials returns
1093 LinuxSecurityLabel where supported
1094 • org.freedesktop.DBus.Monitoring interface (privileged)
1095 · BecomeMonitor method supersedes match rules with eavesdrop=true,
1096 which are now deprecated
1097 • org.freedesktop.DBus.Stats interface (semi-privileged)
1098 · now enabled by default
1099 · new GetAllMatchRules method
1100 • org.freedesktop.DBus.Verbose interface (not normally compiled)
1101 · toggles the effect of DBUS_VERBOSE
1106 • dbus-update-activation-environment
1108 New optional dependencies:
1110 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
1111 • Complete documentation requires Ducktype and yelp-tools
1112 • Full test coverage requires GLib 2.36 and PyGI
1113 • AppArmor integration requires libapparmor and optionally libaudit
1115 Dependencies removed:
1119 D-Bus 1.9.20 (2015-08-06)
1122 The “Remember Tomorrow” release.
1124 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
1129 • Don't second-guess what the ABI of poll() is, allowing it to be used
1130 on Integrity RTOS and other unusual platforms (fd.o #90314;
1131 Rolland Dudemaine, Simon McVittie)
1133 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
1134 both enabled (fd.o #89225, Simon McVittie)
1136 • Log audit events for AppArmor/SELinux policy violations whenever
1137 we have CAP_AUDIT_WRITE, even if not the system bus
1138 (fd.o #83856, Laurent Bigonville)
1140 D-Bus 1.9.18 (2015-07-21)
1143 The “Pirate Elite” release.
1145 Configuration changes:
1147 • The basic setup for the well-known system and session buses is now done
1148 in read-only files in ${datadir}, moving a step closer to systems
1149 that can operate with an empty /etc directory. In increasing order
1152 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
1153 the default message policies.
1154 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
1155 dbus still installs a trivial version of each, for documentation
1156 purposes; putting configuration directives in these files is deprecated.
1157 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
1158 to install "drop-in" configuration snippets (any packages
1159 using those directories should explicitly depend on at least this
1161 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
1162 or third-party software to install "drop-in" configuration snippets
1163 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
1166 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
1167 and "s*" refers to either system or session as appropriate.
1169 (fd.o #89280, Dimitri John Ledkov)
1173 • Fix a memory leak when GetConnectionCredentials() succeeds
1174 (fd.o #91008, Jacek Bukarewicz)
1176 • Ensure that dbus-monitor does not reply to messages intended for others,
1177 resulting in its own disconnection (fd.o #90952, Simon McVittie)
1179 D-Bus 1.9.16 (2015-05-14)
1182 The “titanium barns” release.
1186 • Automake 1.13 is now required when compiling from git or modifying
1191 • On Unix platforms, change the default configuration for the session bus
1192 to only allow EXTERNAL authentication (secure kernel-mediated
1193 credentials-passing), as was already done for the system bus.
1195 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
1196 unpredictable pseudo-random numbers.
1198 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
1199 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1200 NFS or similar, you will need to reconfigure the session bus to accept
1201 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1204 (fd.o #90414, Simon McVittie)
1206 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1207 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1208 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1209 occurs, instead of silently falling back to low-entropy pseudorandom
1210 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1214 • Add dbus_message_iter_get_element_count()
1215 (fd.o #30350; Christian Dywan, Simon McVittie)
1217 • Introduce new internal DBusSocket and DBusPollable types so we can
1218 stop treating the Windows SOCKET type as if it was int. DBusSocket
1219 is specifically a socket, cross-platform. DBusPollable is whatever
1220 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1221 (fd.o #89444; Ralf Habacker, Simon McVittie)
1223 • All regression tests now output TAP <https://testanything.org/>
1224 (fd.o #89846, Simon McVittie)
1226 • Internal APIs consistently use signed values for timestamps
1227 (fd.o #18494, Peter McCurdy)
1229 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1230 (fd.o #88812, Simon McVittie)
1232 • Clean up a lot of compiler warnings
1233 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1237 • Add locking to DBusCounter's reference count and notify function
1238 (fd.o #89297, Adrian Szyndela)
1240 • Ensure that DBusTransport's reference count is protected by the
1241 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1243 • Correctly release DBusServer mutex before early-return if we run out
1244 of memory while copying authentication mechanisms (fd.o #90021,
1247 • Make dbus-test-tool and dbus-update-activation-environment portable
1248 to Windows (fd.o #90089, Ralf Habacker)
1250 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1251 Ralf Habacker, Simon McVittie)
1253 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1256 • Clean up some memory and fd leaks in test code and tools
1257 (fd.o #90021, Ralf Habacker)
1259 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1260 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1262 • CMake generates a versioned shared library even if the revision is 0,
1263 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1265 D-Bus 1.9.14 (2015-03-02)
1268 The “don't stand in the poison cloud” release.
1272 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1273 were previously linked to a static version of libdbus.
1275 • The tests no longer require dbus-glib in order to exercise the libdbus
1276 shared library; they are always linked to libdbus now.
1278 Build-time configuration:
1280 • The new --enable-user-session option, off by default, can be enabled
1281 by OS integrators intending to use systemd to provide a session bus
1282 per user (in effect, treating all concurrent graphical and non-graphical
1283 login sessions as one large session)
1287 • All executables are now linked dynamically to libdbus.
1288 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1290 • On platforms that support them (GNU libc and possibly others),
1291 libdbus now has versioned symbols for its public API.
1292 All public symbols (visible in the header files) are currently
1293 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1294 dbus_internal have a version that changes with each release, and
1295 must not be used by applications. (also fd.o #83115)
1297 • New listenable address mode "unix:runtime=yes" which listens on
1298 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1299 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1301 • Add optional systemd units for a per-user bus listening on
1302 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1304 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1305 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1308 • New dbus-update-activation-environment tool uploads environment
1309 variables to "dbus-daemon --session" and optionally "systemd --user",
1310 primarily as a way to keep the per-user bus compatible with
1311 distributions' existing X11 login scripts (also fd.o #61301)
1313 • <includedir/> elements in dbus-daemon configuration are now silently
1314 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1316 • Add microsecond-resolution timestamps to the default output of
1317 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1321 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1322 (fd.o #89222, Simon McVittie)
1324 D-Bus 1.9.12 (2015-02-19)
1327 The “monster lasagna” release.
1331 • Ducktype and yelp-tools are now required to build complete documentation
1332 (they are optional for normal builds).
1336 • D-Bus Specification version 0.26
1337 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1338 · document the BecomeMonitor method
1340 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1341 (fd.o #89041; Tyler Hicks, Simon McVittie)
1343 • On Linux, add support for AppArmor mediation of message sending and
1344 receiving and name ownership (paralleling existing SELinux mediation
1345 support), and eavesdropping (a new check, currently AppArmor-specific)
1346 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1348 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1349 that have printable ASCII contents; we previously only did this for
1350 unterminated bytestrings (fd.o #89109, Simon McVittie)
1352 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1354 • On Windows, add WindowsSID to GetConnectionCredentials
1355 (fd.o #54445, Ralf Habacker)
1357 • Improve clarity of dbus-monitor --profile output and add more columns
1358 (fd.o #89165, Ralf Habacker)
1360 • Add a man page for dbus-test-tool, and build it under CMake as well
1361 as Autotools (fd.o#89086, Simon McVittie)
1363 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1364 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1365 (fd.o #88896, Ralf Habacker)
1369 • Reduce the number of file descriptors used in the fd-passing test,
1370 avoiding failure under the default Linux fd limit, and automatically
1371 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1373 D-Bus 1.9.10 (2015-02-09)
1376 The “sad cyborgs” release.
1378 Security fixes merged from 1.8.16:
1380 • Do not allow non-uid-0 processes to send forged ActivationFailure
1381 messages. On Linux systems with systemd activation, this would
1382 allow a local denial of service: unprivileged processes could
1383 flood the bus with these forged messages, winning the race with
1384 the actual service activation and causing an error reply
1385 to be sent back when service auto-activation was requested.
1386 This does not prevent the real service from being started,
1387 so the attack only works while the real service is not running.
1388 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1392 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1393 similar tools receive messages without altering the security properties
1394 of the system bus, by calling the new BecomeMonitor method on a
1395 private connection. This bypasses the normal <allow> and <deny> rules
1396 entirely, so to preserve normal message-privacy assumptions, only root
1397 is allowed to do this on the system bus. Restricted environments,
1398 such as Linux with LSMs, should lock down access to the Monitoring
1399 interface. (fd.o #46787, Simon McVittie)
1401 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1402 dbus-daemon supports it and access permissions allow it.
1403 It still supports the previous approach ("eavesdropping" match rules)
1404 for compatibility with older bus daemons. (fd.o #46787, Simon)
1406 • dbus-monitor can now log the message stream as binary data for later
1407 analysis, with either no extra framing beyond the normal D-Bus headers,
1408 or libpcap-compatible framing treating each D-Bus message
1409 as a captured packet. (fd.o #46787, Simon)
1413 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1415 • On Unix, forcibly terminate regression tests after 60 seconds to
1416 prevent them from blocking continuous integration frameworks
1417 (fd.o #46787, Simon)
1419 D-Bus 1.9.8 (2015-02-03)
1422 The “all the types of precipitation” release.
1426 • full test coverage now requires GLib 2.36
1427 • full test coverage now requires PyGI (PyGObject 3,
1428 "import gi.repository.GObject") instead of the
1429 obsolete PyGObject 2 ("import gobject")
1433 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1435 • better regression test coverage, including systemd activation
1436 (fd.o #57952, #88810; Simon McVittie)
1440 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1441 turned off (fd.o #88808, Simon McVittie)
1443 • TCP sockets on Windows no longer fail to listen approximately 1 time
1444 in 256, caused by a logic error that should have always made it fail but
1445 was mitigated by incorrect endianness for the port number
1446 (fd.o #87999, Ralf Habacker)
1448 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1450 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1451 previous 64, completing a previous fix which only worked under
1452 Autotools (fd.o #71297, Ralf Habacker)
1454 • on Windows, if the IP family is unspecified only use IPv4,
1455 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1457 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1459 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1461 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1464 D-Bus 1.9.6 (2015-01-05)
1467 The “I do have a bread knife” release.
1471 • Do not allow calls to UpdateActivationEnvironment from uids other than
1472 the uid of the dbus-daemon. If a system service installs unsafe
1473 security policy rules that allow arbitrary method calls
1474 (such as CVE-2014-8148) then this prevents memory consumption and
1475 possible privilege escalation via UpdateActivationEnvironment.
1477 We believe that in practice, privilege escalation here is avoided
1478 by dbus-daemon-launch-helper sanitizing its environment; but
1479 it seems better to be safe.
1481 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1482 on object paths other than /org/freedesktop/DBus. Some system services
1483 install unsafe security policy rules that allow arbitrary method calls
1484 to any destination, method and interface with a specified object path;
1485 while less bad than allowing arbitrary method calls, these security
1486 policies are still harmful, since dbus-daemon normally offers the
1487 same API on all object paths and other system services might behave
1492 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1493 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1495 D-Bus 1.9.4 (2014-11-24)
1498 The “extra-sturdy caramel” release.
1502 • Partially revert the CVE-2014-3639 patch by increasing the default
1503 authentication timeout on the system bus from 5 seconds back to 30
1504 seconds, since this has been reported to cause boot regressions for
1505 some users, mostly with parallel boot (systemd) on slower hardware.
1507 On fast systems where local users are considered particularly hostile,
1508 administrators can return to the 5 second timeout (or any other value
1509 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1512 <limit name="auth_timeout">5000</limit>
1515 (fd.o #86431, Simon McVittie)
1517 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1518 (fd.o #86431, Simon McVittie)
1520 • Send back an AccessDenied error if the addressed recipient is not allowed
1521 to receive a message (and in builds with assertions enabled, don't
1522 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1524 D-Bus 1.9.2 (2014-11-10)
1527 The “structurally unsound flapjack” release.
1531 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1532 so that CVE-2014-3636 part A cannot exhaust the system bus'
1533 file descriptors, completing the incomplete fix in 1.8.8.
1534 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1538 • D-Bus Specification version 0.25
1539 · new value 'const' for EmitsChangedSignal annotation
1540 (fd.o #72958, Lennart Poettering)
1541 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1542 (fd.o #83449; Lennart Poettering, Simon McVittie)
1543 · annotate table of types with reserved/basic/container, and for
1544 basic types, fixed/string-like
1545 · clarify arbitrary limits by quoting them in mebibytes
1547 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1548 (fd.o #83449, Simon McVittie)
1550 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1551 useful for debugging and performance testing:
1552 · dbus-test-tool spam: send repeated messages
1553 · dbus-test-tool echo: send an empty reply for all method calls
1554 · dbus-test-tool black-hole: do not reply to method calls
1555 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1557 • Add support for process ID in credentials-passing on NetBSD
1558 (fd.o #69702, Patrick Welche)
1560 • Add an example script to find potentially undesired match rules
1561 (fd.o #84598, Alban Crequy)
1563 • Document the central assumption that makes our use of credentials-passing
1564 secure (fd.o #83499, Simon McVittie)
1566 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1567 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1572 • Use a less confusing NoReply message when disconnected with a reply pending
1573 (fd.o #76112, Simon McVittie)
1575 • Make the .pc file relocatable by letting pkg-config do all variable
1576 expansion itself (fd.o #75858, Руслан Ижбулатов)
1578 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1579 (fd.o #85563, Patrick Welche)
1581 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1583 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1584 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1586 • Do not fail the tests if a parent process has leaked non-close-on-exec
1587 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1589 • Do not fail the tests on Unix platforms with incomplete
1590 credentials-passing support, but do fail if we can't pass credentials
1591 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1592 (fd.o #69702, Simon McVittie)
1594 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1595 when building with cmake, and expand test coverage there
1596 (fd.o #73689; Ralf Habacker, Simon McVittie)
1598 D-Bus 1.9.0 (2014-10-01)
1601 The “tiered cheeses” release.
1605 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1606 requires either the libsystemd or libsd-daemon shared library, dropping the
1607 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1609 Build-time configuration changes:
1611 • The Stats interface is now enabled by default, and locked-down to
1612 root-only on the system bus. Configure with --disable-stats
1613 to disable it altogether on memory- or disk-constrained systems,
1614 or see ${docdir}/examples/ to open it up to non-root users on the
1615 system bus or restrict access on the session bus.
1616 (fd.o #80759; Simon McVittie, Alban Crequy)
1618 • The CMake build system now builds the same shared library name as Autotools
1619 on at least Linux and Windows:
1620 - on Linux (and perhaps other Unix platforms), it previously built
1621 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1622 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1623 - on Windows, it previously built either libdbus-1.dll (release) or
1624 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1625 libdbus-1.dll for compatibility with older applications.
1626 (fd.o #74117, Ralf Habacker)
1630 • D-Bus Specification version 0.24
1631 · document how to quote match rules (fd.o #24307, Simon McVittie)
1632 · explicitly say that most message types never expect a reply
1633 regardles of whether they have NO_REPLY_EXPECTED
1634 (fd.o #75749, Simon McVittie)
1636 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
1637 initial latency (fd.o #75544, Matt Hoosier)
1639 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
1640 (fd.o #69702, Patrick Welche)
1642 • in dbus-monitor, print more information about file descriptors
1643 (fd.o #80603, Alban Crequy)
1645 • do not install system bus configuration if built for Windows
1646 (fd.o #83583; Ralf Habacker, Simon McVittie)
1648 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
1650 • Add a regression test for file descriptor passing (fd.o #83622,
1655 • fix an incorrect error message if a Unix socket path is too long
1656 (fd.o #73887, Antoine Jacoutot)
1658 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
1659 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
1661 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
1662 in ps(1) (fd.o #69716, Chengwei Yang)
1664 • avoid calling poll() with timeout < -1, which is considered invalid
1665 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
1667 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
1668 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
1669 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
1671 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
1673 • Documentation improvements
1674 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
1676 • in dbus-monitor, do not leak file descriptors that we have monitored
1677 (fd.o #80603, Alban Crequy)
1679 • Set the close-on-exec flag for the inotify file descriptor, even
1680 if built with CMake or older libc (fd.o #73689, Simon McVittie)
1682 • Remove some LGPL code from the Windows dbus-daemon
1683 (fd.o #57272, Ralf Habacker)
1685 D-Bus 1.8.8 (2014-09-16)
1688 The "smashy smashy egg man" release.
1692 • Do not accept an extra fd in the padding of a cmsg message, which
1693 could lead to a 4-byte heap buffer overrun.
1694 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1696 • Reduce default for maximum Unix file descriptors passed per message
1697 from 1024 to 16, preventing a uid with the default maximum number of
1698 connections from exhausting the system bus' file descriptors under
1699 Linux's default rlimit. Distributors or system administrators with a
1700 more restrictive fd limit may wish to reduce these limits further.
1702 Additionally, on Linux this prevents a second denial of service
1703 in which the dbus-daemon can be made to exceed the maximum number
1704 of fds per sendmsg() and disconnect the process that would have
1706 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1708 • Disconnect connections that still have a fd pending unmarshalling after
1709 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1710 removing the possibility of creating an abusive connection that cannot be
1711 disconnected by setting up a circular reference to a connection's
1713 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1715 • Reduce default for maximum pending replies per connection from 8192 to 128,
1716 mitigating an algorithmic complexity denial-of-service attack
1717 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1719 • Reduce default for authentication timeout on the system bus from
1720 30 seconds to 5 seconds, avoiding denial of service by using up

1722 connection slots are used up, make new connection attempts block
1723 instead of disconnecting them.

1728 • Check for libsystemd from systemd >= 209, falling back to
1729 the older separate libraries if not found (Umut Tezduyar Lindskog,
1732 • On Linux, use prctl() to disable core dumps from a test executable
1733 that deliberately raises SIGSEGV to test dbus-daemon's handling
1734 of that condition (fd.o #83772, Simon McVittie)

1747 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1748 the message. This prevents an attack in which a malicious client can
1749 make dbus-daemon disconnect a system service, which is a local

1753 • Track remaining Unix file descriptors correctly when more than one
1754 message in quick succession contains fds. This prevents another attack
1755 in which a malicious client can make dbus-daemon disconnect a system

1763 attach to a session, kill the dbus-daemon as intended
1764 (fd.o #74698, Роман Донченко)
1766 D-Bus 1.8.4 (2014-06-10)
1771 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1772 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1773 Additionally, in highly unusual environments the same flaw could lead to
1774 a side channel between processes that should not be able to communicate.
1775 (CVE-2014-3477, fd.o #78979)
1777 D-Bus 1.8.2 (2014-04-30)
1780 The “nobody wants red” release.
1784 • in the CMake build system, add some hints for Linux users cross-compiling
1785 Windows D-Bus binaries to be able to run tests under Wine
1786 (fd.o #41252, Ralf Habacker)
1788 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
1792 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
1793 to /var/lib/dbus/machine-id instead of generating an entirely new ID

1796 • if dbus-launch receives an X error very quickly, do not kill
1797 unrelated processes (fd.o #74698, Роман Донченко)
1799 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
1800 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
1802 • cope with \r\n newlines in regression tests, since on Windows,
1803 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
1805 D-Bus 1.8.0 (2014-01-20)
1808 The “Wolverine distrusts my printer” release.
1810 This starts a new stable branch. The 1.6.x branch is now considered to be
1811 outdated, and will only receive fixes for serious bugs such as security
1812 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1813 are unlikely to get any more releases, but if distributors still need to
1814 support them, please share security patches via upstream.
1816 Summary of changes since 1.6.x:
1818 • libdbus always behaves as if dbus_threads_init_default() had been called
1819 (thread-safety by default)
1820 • new dbus-run-session tool, replacing certain misuses of dbus-launch
1821 • dbus-monitor can talk to outdated versions of dbus-daemon again
1822 • new org.freedesktop.DBus.GetConnectionCredentials method
1823 • GetConnectionUnixProcessID also works correctly on Windows, returning
1824 the Windows process ID
1825 • GetConnectionWindowsSID returns the correct SID on Windows
1826 • expat is required, libxml2 can no longer be used as a substitute
1827 • the userDB cache is required, and cannot be disabled
1828 • a 64-bit integer type (either int, long, long long or _int64) is required
1829 • better systemd-journald integration on Linux
1830 • fixed long-standing fd and array leaks when failing to parse a message
1831 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
1832 when using certain object-path allocation patterns, notably in Avahi
1833 • better defaults for Windows support
1834 • better CMake support
1835 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
1836 • the source language for the man pages is now Docbook XML
1838 Enhancements since 1.7.10:
1840 • Enhance the CMake build system to check for GLib and compile/run
1841 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
1845 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
1848 • fix compilation of systemd journal support on older systemd versions where
1849 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
1851 • fix compilation on older MSVC versions by including stdlib.h
1852 (fd.o #73455, Ralf Habacker)
1854 • Allow <allow_anonymous/> to appear in an included configuration file
1855 (fd.o #73475, Matt Hoosier)
1857 Test behaviour changes since 1.7.10:
1859 • If the tests crash with an assertion failure, they no longer default to
1860 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
1861 environment if you want the old behaviour.
1863 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
1864 can be run with an external dbus-daemon by setting
1865 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
1866 an unusually-configured dbus-daemon are skipped.
1868 D-Bus 1.7.10 (2014-01-06)
1871 The “weighted companion cube” release.
1873 This is a release candidate for D-Bus 1.8.
1875 D-Bus Specification 0.23:
1877 • don't require messages with no INTERFACE to be dispatched
1878 (fd.o #68597, Simon McVittie)
1880 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
1883 • define "listenable" and "connectable" addresses, and discuss
1884 the difference (fd.o #61303, Simon McVittie)
1888 • support printing Unix file descriptors in dbus-send, dbus-monitor
1889 (fd.o #70592, Robert Ancell)
1891 • don't install systemd units if --disable-systemd is given
1892 (fd.o #71818, Chengwei Yang)
1896 • don't leak memory on out-of-memory while listing activatable or
1897 active services (fd.o #71526, Radoslaw Pajak)
1899 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
1901 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
1903 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
1904 and DBUS__SEND_MSG are numerically equal to their values in the
1905 reference policy (fd.o #88719, osmond sun)
1907 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
1908 (fd.o #71366, Matt Fischer)
1910 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
1911 winsock2.h (fd.o #71405, Matt Fischer)
1913 • do not return failure from _dbus_read_nonce() with no error set,
1914 preventing a potential crash (fd.o #72298, Chengwei Yang)
1916 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
1917 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
1919 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
1920 which doesn't do anything anyway on at least Linux and FreeBSD
1921 (fd.o #69492, Simon McVittie)
1923 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
1924 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
1925 for credentials more correctly (fd.o #69492, Simon McVittie)
1927 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
1928 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
1931 • refresh cached policy rules for existing connections when bus
1932 configuration changes (fd.o #39463, Chengwei Yang)
1934 D-Bus 1.7.8 (2013-11-01)
1937 The “extreme hills” release.
1941 • If systemd support is enabled, libsystemd-journal is now required.
1945 • When activating a non-systemd service under systemd, annotate its
1946 stdout/stderr with its bus name in the Journal. Known limitation:
1947 because the socket is opened before forking, the process will still be
1948 logged as if it had dbus-daemon's process ID and user ID.
1949 (fd.o #68559, Chengwei Yang)
1951 • Document more configuration elements in dbus-daemon(1)
1952 (fd.o #69125, Chengwei Yang)
1956 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
1957 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
1959 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
1960 disallowed method calls to the audit log, fixing a regression in 1.7.6
1961 (fd.o #49062, Colin Walters)
1963 • path_namespace='/' in match rules incorrectly matched nothing; it
1964 now matches everything. (fd.o #70799, Simon McVittie)
1966 D-Bus 1.7.6 (2013-10-09)
1969 The “CSI Shrewsbury” release.
1971 Build-time configuration changes:
1973 • Directory change notification via dnotify on Linux is no longer
1974 supported; it hadn't compiled successfully since 2010 in any case.
1975 If you don't have inotify (Linux) or kqueue (*BSD), you will need
1976 to send SIGHUP to the dbus-daemon when its configuration changes.
1977 (fd.o #33001, Chengwei Yang)
1979 • Compiling with --disable-userdb-cache is no longer supported;
1980 it didn't work since at least 2008, and would lead to an extremely
1981 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
1984 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
1985 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
1986 with the Autotools build system. (fd.o #66142, Chengwei Yang)
1988 • --with-valgrind=auto enables Valgrind instrumentation if and only if
1989 valgrind headers are available. The default is still --with-valgrind=no.
1990 (fd.o #56925, Simon McVittie)
1994 • Platforms with no 64-bit integer type are no longer supported.
1995 (fd.o #65429, Simon McVittie)
1997 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
1999 • Full test coverage no longer requires dbus-glib, although the tests do not
2000 exercise the shared library (only a static copy) if dbus-glib is missing.
2001 (fd.o #68852, Simon McVittie)
2005 • D-Bus Specification 0.22
2006 · Document GetAdtAuditSessionData() and
2007 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
2008 · Fix example .service file (fd.o #66481, Chengwei Yang)
2009 · Don't claim D-Bus is "low-latency" (lower than what?), just
2010 give factual statements about it supporting async use
2011 (fd.o #65141, Justin Lee)
2012 · Document the contents of .service files, and the fact that
2013 system services' filenames are constrained
2014 (fd.o #66608; Simon McVittie, Chengwei Yang)
2016 • Be thread-safe by default on all platforms, even if
2017 dbus_threads_init_default() has not been called. For compatibility with
2018 older libdbus, library users should continue to call
2019 dbus_threads_init_default(): it is harmless to do so.
2020 (fd.o #54972, Simon McVittie)
2022 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
2024 • New API: dbus_setenv(), a simple wrapper around setenv().
2025 Note that this is not thread-safe. (fd.o #39196, Simon)
2027 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
2028 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
2029 (connect to a given bus, like dbus-monitor --address=ADDRESS).
2030 dbus-send --address still exists for backwards compatibility,
2031 but is no longer documented. (fd.o #48816, Andrey Mazo)
2034 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
2039 • Avoid an infinite busy-loop if a signal interrupts waitpid()
2040 (fd.o #68945, Simon McVittie)
2042 • Clean up memory for parent nodes when objects are unexported
2043 (fd.o #60176, Thomas Fitzsimmons)
2045 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
2046 documented. Previously, it assumed its second parameter was TRUE.
2047 (fd.o #69165, Chengwei Yang)
2049 • Escape addresses containing non-ASCII characters correctly
2050 (fd.o #53499, Chengwei Yang)
2052 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
2054 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
2055 (fd.o #65923, Chengwei Yang)
2057 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
2058 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
2060 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
2061 that was never va_start()ed (fd.o #66300, Chengwei Yang)
2063 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
2065 • fix a regression test on platforms with strict alignment (fd.o #67279,
2068 • Avoid calling function parameters "interface" since certain Windows headers
2069 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
2071 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
2073 • Various thread-safety improvements to static variables (fd.o #68610,
2076 • Make "make -j check" work (fd.o #68852, Simon McVittie)
2078 • Fix a NULL pointer dereference on an unlikely error path
2079 (fd.o #69327, Sviatoslav Chagaev)
2081 • Improve valgrind memory pool tracking (fd.o #69326,
2084 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
2087 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
2088 (fd.o #66107, Chengwei Yang)
2091 · If accept4() fails with EINVAL, as it can on older Linux kernels
2092 with newer glibc, try accept() instead of going into a busy-loop.
2093 (fd.o #69026, Chengwei Yang)
2094 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
2095 for instance on Hurd or older Linux with a new glibc, try without
2096 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)

2102 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
2103 · Use dbus-launch from the builddir for testing, not the installed copy
2104 (fd.o #37849, Chengwei Yang)
2105 · Fix compilation if writev() is unavailable (fd.o #69409,
2107 · Remove broken support for LOCAL_CREDS credentials passing, and
2108 document where each credential-passing scheme is used (fd.o #60340,

2134 Chengwei Yang, Vasiliy Balyasnyy)
2136 D-Bus 1.7.4 (2013-06-13)
2139 The “but is your thread-safety thread-safe?” release.
2143 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
2144 of service for system services. Vulnerability reported by Alexandru Cornea.
2149 • The Windows version of libdbus now contains a C++ source file, used
2150 to provide global initialization when the library is loaded.
2151 gcc (mingw*) users should ensure that g++ is also installed.
2153 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
2154 and was never the recommended option) has been removed. Expat is now a
2159 • It should now be safe to call dbus_threads_init_default() from any thread,
2160 at any time. Authors of loadable modules and plugins that use libdbus
2161 should consider doing so during initialization.
2162 (fd.o #54972, Simon McVittie)
2164 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
2168 · dbus-run-session: experimental new tool to start a temporary D-Bus
2169 session, e.g. for regression tests or a text console, replacing
2170 certain uses of dbus-launch which weren't really correct
2171 (fd.o #39196, Simon)
2175 • In dbus-daemon, don't crash if a .service file starts with key=value
2176 (fd.o #60853, Chengwei Yang)
2179 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
2180 on a platform not defining LOG_PERROR, such as Solaris or QNX.
2181 This regressed in 1.7.0. (Simon)
2182 · Fix an assertion failure if we try to activate systemd services before
2183 systemd connects to the bus (fd.o #50199, Chengwei Yang)
2184 · Avoid compiler warnings for ignoring the return from write()
2188 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
2189 so that Windows finds them (fd.o #59733, Ralf Habacker)
2191 D-Bus 1.7.2 (2013-04-25)
2194 The “only partially opaque” release.
2196 Configuration changes:
2198 • On non-QNX Unix platforms, the default limit on fds per message in the
2199 session bus configuration has reduced from 4096 to 1024. The default
2200 limit used on the system bus was already 1024. On QNX, both limits are
2201 reduced further, to 128.
2205 • D-Bus Specification 0.21
2206 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
2207 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
2212 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
2213 (i.e. before allocating the slot) rather than returning junk
2214 (fd.o #63127, Dan Williams)
2216 • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker,
2220 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
2221 · Under systemd, log to syslog only, not stderr, avoiding duplication
2222 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
2223 · Under systemd, remove unnecessary dependency on syslog.socket
2224 (fd.o #63531, Cristian Rodríguez)
2225 · Include alloca.h for alloca() if available, fixing compilation on
2226 Solaris 10 (fd.o #63071, Dagobert Michelsen)
2227 · Allow use of systemd-logind without the rest of systemd
2228 (fd.o #62585, Martin Pitt)

2231 · Reduce the default limit on number of fds per message to 128 under
2232 QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer)
2235 · Do not claim that all bus clients have the dbus-daemon's credentials;

2237 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,
2240 D-Bus 1.7.0 (2013-02-22)
2243 The "Disingenuous Assertions" release.
2245 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
2246 remains the recommended version for long-term-supported distributions
2247 or the upcoming GNOME 3.8 release.
2249 Build-time configuration changes:
2251 • The --with-dbus-session-bus-default-address configure option is no longer
2252 supported. Use the new --with-dbus-session-bus-connect-address and
2253 --with-dbus-session-bus-listen-address options instead. On Windows, you
2254 usually want them to have the same argument; on Unix, the defaults are
2257 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2258 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2259 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2261 • cmake/cross-compile.sh has been removed. Instead, please use a
2262 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2263 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2264 as documented in "info automake Cross-Compilation", and set
2265 PKG_CONFIG_PATH appropriately.
2269 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
2270 • man2html is no longer used.
2274 • D-Bus Specification 0.20
2275 · actually say that /org/freedesktop/DBus is the object that
2276 implements o.fd.DBus (fd.o #51865, Colin Walters)
2277 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
2278 · stop claiming that all basic types work just like INT32 (strings don't!)
2280 • The "source code" for the man pages is now Docbook XML, eliminating
2281 the outdated duplicate copies used when building with CMake.
2282 (fd.o #59805; Ralf Habacker, Simon McVittie)
2286 • In the activation helper, when compiled for tests, do not reset the system
2287 bus address, fixing the regression tests. (fd.o #52202, Simon)
2289 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
2290 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
2292 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,
2295 • Under CMake, prefer xmlto over meinproc (fd.o #59733, Ralf Habacker)

2307 (at least) OpenBSD (fd.o #47239, Simon)
2308 · Don't leak temporary fds pointing to /dev/null (fd.o #56927,
2310 · Update sd-daemon.[ch] from systemd (fd.o #60681)
2311 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
2314 · The default session bus listening and connecting address is now
2315 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2316 and GDBus "out of the box". Use the configure options and cmake variables
2317 described above if you require a different autolaunch scope.
2318 (fd.o #38201, Simon McVittie)
2319 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
2321 • Create session.d, system.d directories under CMake (fd.o #41319,

2327 The "Fix one thing, break another" release.
2329 • Follow up to CVE-2012-3524: The additional hardening
2330 work to use __secure_getenv() as a followup to bug #52202

2375 (fd.o #51032, Simon McVittie)
2377 • Disconnect "developer mode" (assertions, verbose mode etc.) from
2378 Automake maintainer mode. D-Bus developers should now configure with
2379 --enable-developer. Automake maintainer mode is now on by default;
2380 distributions can disable it with --disable-maintainer-mode.
2381 (fd.o #34671, Simon McVittie)
2383 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,

2387 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
2389 D-Bus 1.6.0 (2012-06-05)
2392 The “soul of this machine has improved” release.
2394 This version starts a new stable branch of D-Bus: only bug fixes will
2395 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
2397 Summary of changes since 1.4.x:
2400 · PTHREAD_MUTEX_RECURSIVE on Unix
2401 · compiler support for 64-bit integers (int64_t or equivalent)
2403 • D-Bus Specification v0.19
2405 • New dbus-daemon features
2406 · <allow own_prefix="com.example.Service"/> rules allow the service to
2407 own names like com.example.Service.Instance3
2408 · optional systemd integration when checking at_console policies
2409 · --nopidfile option, mainly for use by systemd
2410 · path_namespace and arg0namespace may appear in match rules

2414 · functions to validate various string types (dbus_validate_path() etc.)
2415 · dbus_type_is_valid()
2416 · DBusBasicValue, a union of every basic type
2419 · removed an unsafe reimplementation of recursive mutexes
2420 · dbus-daemon no longer busy-loops if it has far too many file descriptors
2421 · dbus-daemon.exe --print-address works on Windows
2422 · all the other bug fixes from 1.4.20
2424 • Other major implementation changes
2425 · on Linux, dbus-daemon uses epoll if supported, for better scalability
2426 · dbus_threads_init() ignores its argument and behaves like
2427 dbus_threads_init_default() instead
2428 · removed the per-connection link cache, improving dbus-daemon performance
2430 • Developer features
2431 · optional Valgrind instrumentation (--with-valgrind)
2432 · optional Stats interface on the dbus-daemon (--enable-stats)
2433 · optionally abort whenever malloc() fails (--enable-embedded-tests
2434 and export DBUS_MALLOC_CANNOT_FAIL=1)
2436 Changes since 1.5.12:
2438 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
2439 spec-compliance (fd.o #48580, David Zeuthen)
2441 • Don't use install(1) within the source/build trees, fixing the build as
2442 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
2444 • Add missing commas in some tcp and nonce-tcp addresses, and remove
2445 an unused duplicate copy of the nonce-tcp transport in Windows builds
2446 (fd.o #45896, Simon McVittie)
2448 D-Bus 1.5.12 (2012-03-27)
2451 The “Big Book of Science” release.
2453 • Add public API to validate various string types:
2454 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
2455 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
2456 (fd.o #39549, Simon McVittie)
2458 • Turn DBusBasicValue into public API so bindings don't need to invent their
2459 own "union of everything" type (fd.o #11191, Simon McVittie)
2461 • Enumerate data files included in the build rather than using find(1)
2462 (fd.o #33840, Simon McVittie)
2464 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
2465 in dbus-daemon (fd.o #46273, Alban Crequy)
2468 · make dbus-daemon.exe --print-address (and --print-pid) work again
2469 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
2470 · fix duplicate case value when compiling against mingw-w64
2471 (fd.o #47321, Andoni Morales Alastruey)
2473 D-Bus 1.5.10 (2012-02-21)
2476 The "fire in Delerium" release.
2478 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2479 and SUSv2) is now required.
2481 • D-Bus Specification 0.19:
2482 · Formally define unique connection names and well-known bus names,
2483 and document best practices for interface, bus, member and error names,
2484 and object paths (fd.o #37095, Simon McVittie)
2485 · Document the search path for session and system services on Unix, and
2486 where they should be installed by build systems (fd.o #21620, fd.o #35306;
2488 · Document the systemd transport (fd.o #35232, Lennart Poettering)
2490 • Make dbus_threads_init() use the same built-in threading implementation
2491 as dbus_threads_init_default(); the user-specified primitives that it
2492 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
2494 • Allow all configured auth mechanisms, not just one (fd.o #45106,
2497 • Improve cmake build system (Ralf Habacker):
2498 · simplify XML parser dependencies (fd.o #41027)
2499 · generate build timestamp (fd.o #41029)
2500 · only create batch files on Windows
2501 · fix option and cache syntax
2502 · add help-options target
2503 · share dbus-arch-deps.h.in with autotools rather than having our
2504 own version (fd.o #41033)
2506 • Build tests successfully with older GLib, as found in e.g. Debian 6
2507 (fd.o #41219, Simon McVittie)
2509 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
2511 • Build documentation correctly if man2html doesn't support filenames on
2512 its command-line (fd.o #43875, Jack Nagel)
2514 • Improve test coverage. To get even more coverage, run the tests with
2515 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
2517 • Reduce the size of the shared library by moving functionality only used
2518 by dbus-daemon, tests etc. into their internal library and deleting
2519 unused code (fd.o #34976, #39759; Simon McVittie)
2521 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2522 setups where the default configuration must include <pidfile/> to avoid
2523 breaking traditional init, but the pid file is in fact unnecessary; use
2524 it under systemd to improve startup time a bit (fd.o #45520,
2527 • Optionally (if configured --with-valgrind) add instrumentation to debug
2528 libdbus and associated tools more meaningfully under Valgrind
2529 (fd.o #37286, Simon McVittie)
2531 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
2533 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
2535 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
2536 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
2537 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
2540 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
2544 · Replace our broken reimplementation of recursive mutexes, which has
2545 been broken since 2006, with an ordinary pthreads recursive mutex
2546 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2547 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2548 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2549 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2550 · When running under systemd, use it instead of ConsoleKit to check
2551 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2552 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2553 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2554 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2555 (fd.o #41218, Simon McVittie)
2556 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2557 helper doesn't obey environment variables to avoid privilege escalation
2558 attacks, so make the system bus follow the same rules
2559 (fd.o #21620, Simon McVittie)
2562 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2563 Jesper Dam, Ralf Habacker)
2564 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
2567 D-Bus 1.5.8 (2011-09-21)
2570 The "cross-metering" release.
2572 In addition to dead code removal and refactoring, this release contains all
2573 of the bugfixes from 1.4.16.
2575 • Clean up dead code, and make more warnings fatal in development builds
2576 (fd.o #39231, fd.o #41012; Simon McVittie)
2578 • If full test coverage is requested via --enable-tests, strictly require
2579 Python, pygobject and dbus-python, which are required by some tests; if not,
2580 and Python is missing, skip those tests rather than failing
2581 (fd.o #37847, Simon McVittie)
2583 • When using cmake, provide the same version-info API in the installed headers
2584 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2586 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
2588 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
2590 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
2593 • Fix duplicates in authors list (Ralf Habacker)
2595 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2596 (fd.o #39879, Chris Mayo)
2598 • Fix a small memory leak, and a failure to report errors, when updating
2599 a service file entry for activation (fd.o #39230, Simon McVittie)
2602 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2603 Brian Cameron, Simon McVittie)
2604 · On systems that use libcap-ng but not systemd, drop supplemental groups
2605 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2606 · Make the cmake build work again on GNU platforms (fd.o #29228,
2608 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
2609 like Solaris (fd.o #40313, Dagobert Michelsen)
2610 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2611 (fd.o #40235, Simon McVittie)
2612 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2613 (fd.o #39987, Simon McVittie)
2614 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2615 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2618 · Fix compilation on MSVC, which doesn't understand "inline" with its
2619 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2620 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2621 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2623 D-Bus 1.5.6 (2011-07-29)
2626 The "weird, gravy-like aftertaste" release.
2628 In addition to new features and refactoring, this release contains all of the
2629 bugfixes from 1.4.14.
2631 Potentially incompatible (Bustle and similar debugging tools will need
2632 changes to work as intended):
2634 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2635 different recipient) by mistake: eavesdroppers must now opt-in to this
2636 behaviour by putting "eavesdrop='true'" in the match rule, which will
2637 not have any practical effect on buses where eavesdropping is not allowed
2638 (fd.o #37890, Cosimo Alfarano)
2642 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2643 Cosimo Alfarano, Simon McVittie)
2644 · add the "eavesdrop" keyword to match rules
2645 · define eavesdropping, unicast messages and broadcast messages
2646 · stop claiming that match rules are needed to match unicast messages to you
2647 · promote the type system to be a top-level section
2649 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2650 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2651 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2653 • Consistently use atomic operations on everything that is ever manipulated
2654 via atomic ops, as was done for changes to DBusConnection's refcount in
2655 1.4.12 (fd.o #38005, Simon McVittie)
2657 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2660 • Make "make check" in a clean tree work, by not running tests until
2661 test data has been set up (fd.o #34405, Simon McVittie)
2663 • The dbus-daemon no longer busy-loops if it has a very large number of file
2664 descriptors (fd.o #23194, Simon McVittie)
2666 • Refactor message flow through dispatching to avoid locking violations if
2667 the bus daemon's message limit is hit; remove the per-connection link cache,
2668 which was meant to improve performance, but now reduces it (fd.o #34393,
2671 • Some cmake fixes (Ralf Habacker)
2673 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2674 Simon McVittie, Lennart Poettering)
2676 • Stop storing two extra byte order indicators in each D-Bus message
2677 (fd.o #38287, Simon McVittie)
2679 • Add an optional Stats interface which can be used to get statistics from
2680 a running dbus-daemon if enabled at configure time with --enable-stats
2681 (fd.o #34040, Simon McVittie)
2683 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2685 • Documentation (fd.o #36156, Simon McVittie):
2686 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2687 · install more documentation automatically, including man2html output
2688 · put dbus.devhelp in the right place (it must go in ${htmldir})
2691 · look for system services in /lib/dbus-1/system-services in addition to all
2692 the other well-known locations; note that this should always be /lib,
2693 even on platforms where shared libraries on the root FS would go in /lib64,
2694 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2695 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2697 • Windows-specific (Ralf Habacker):
2698 · fix use of a mutex for autolaunch server detection
2699 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2701 D-Bus 1.5.4 (2011-06-10)
2704 Security (local denial of service):
2706 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2707 local DoS if foreign-endian messages are relayed through the dbus-daemon
2708 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2709 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2713 • The constant to use for an infinite timeout now has a name,
2714 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2715 which can be used for source compatibility with older versions of libdbus.
2717 • If GLib and DBus-GLib are already installed, more tests will be built,
2718 providing better coverage. The new tests can also be installed via
2719 ./configure --enable-installed-tests
2720 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2724 • Consistently use atomic operations for the DBusConnection's refcount,
2725 fixing potential threading problems (fd.o #38005, Simon McVittie)
2727 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2728 small (300KiB on x86-64) and it frequently doesn't work in unusual
2729 toolchains. To optimize for minimum installed size, you should benchmark
2730 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2731 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2733 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2734 (fd.o #35880, Timothy Redaelli)
2736 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2737 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2739 • Windows-specific changes:
2740 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2742 D-Bus 1.5.2 (2011-06-01)
2745 The "Boar Hunter" release.
2747 Notes for distributors:
2749 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2750 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2751 toolchain supports it reliably, via something like:
2753 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2755 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2759 • D-Bus Specification v0.17
2760 · Reserve the extra characters used in signatures by GVariant
2761 (fd.o #34529, Simon McVittie)
2762 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2763 • Don't force -fPIE: distributions and libtool know better than we do whether
2764 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2765 • Allow --disable-gc-sections, in case your toolchain offers the
2766 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2767 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2768 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2769 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2770 • Ensure that maintainers upload documentation with the right permissions
2771 (fd.o #36130, Simon McVittie)
2772 • Don't force users of libdbus to be linked against -lpthread, -lrt
2773 (fd.o #32827, Simon McVittie)
2774 • Log system-bus activation information to syslog (fd.o #35705,
2776 • Log messages dropped due to quotas to syslog (fd.o #35358,
