1 D-Bus 1.11.20 (UNRELEASED)
6 D-Bus 1.11.18 (2017-09-25)
9 The “vampire conquistador” release.
11 Build-time configuration changes:
13 • By default, dbus-daemon on Unix no longer checks for flag files
14 /var/run/console/${username} created by the obsolete pam_console and
15 pam_foreground PAM modules when deciding whether ${username} is
16 currently at the console. The old default behaviour can be restored
17 by specifying --with-console-auth-dir=/var/run/console in the
18 recommended Autotools build system, or
19 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
20 now deprecated, and will be removed in dbus 1.13 unless feedback via
21 fd.o #101629 indicates that this would be problematic.
22 (fd.o #101629, Simon McVittie)
24 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
25 script for Cygwin, are no longer provided in the upstream dbus
26 source. We recommend that distributors who support non-systemd service
27 management should maintain their own init scripts or other service
28 manager integration as part of their downstream packaging, similar to
29 the way Debian distributes a Debian-specific LSB init script for dbus.
31 The systemd unit continues to be maintained as part of the upstream
32 dbus source, because it receives regular testing and maintenance.
34 (fd.o #101706, Simon McVittie)
36 • The process ID file created by the system bus is no longer influenced
37 by the --with-init-scripts=redhat configure option or the presence of
38 /etc/redhat-release at build time. If your OS's init script or other
39 service management relies on the Red Hat-style pid file, it can be
40 restored by specifying --with-system-pid-file=/run/messagebus.pid at
41 configure time or using the <pidfile> directive in bus configuration.
43 Note that the upstream-supplied systemd unit runs dbus-daemon with
44 the --nopidfile option, so it does not normally write a pid file,
45 regardless of whether the OS is Red-Hat-derived or not.
47 (fd.o #101706, Simon McVittie)
51 • <allow> and <deny> rules in dbus-daemon configuration can now
52 include send_broadcast="true" or send_broadcast="false", which make
53 the rule only match broadcast signals, or only match messages that
54 are not broadcast signals, respectively.
55 (fd.o #29853, Simon McVittie)
57 • <allow> and <deny> rules can now be configured to apply only to
58 messages with or without Unix file descriptors attached. This would
59 typically be used in rules like these:
60 <allow send_destination="..." max_unix_fds="0"/>
61 <deny send_destination="..." min_unix_fds="1"/>
62 <deny receive_sender="..." min_unix_fds="1"/>
63 but can also be used to set a nonzero upper limit on the number of
65 <allow send_destination="..." max_unix_fds="4"/>
66 (fd.o #101848, Simon McVittie)
68 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
69 now respects the HOME environment variable on the client side, and
70 on the server side when the uid attempting to connect is the same
71 as the uid of the server. This allows the automated tests to pass in
72 environments where the user's "official" home directory in /etc/passwd
73 is nonexistent, such as Debian autobuilders.
74 (fd.o #101960, Simon McVittie)
78 • When parsing dbus-daemon configuration, tell Expat not to use
79 cryptographic-quality entropy as a salt for its hash tables: we trust
80 the configuration files, so we are not concerned about algorithmic
81 complexity attacks via hash table collisions. This prevents
82 dbus-daemon --system from holding up the boot process (and causing
83 early-boot system services like systemd, logind, networkd to time
84 out) on entropy-starved embedded systems.
85 (fd.o #101858, Simon McVittie)
87 • Avoid a -Werror=declaration-after-statement build failure on Solaris
88 (fd.o #102145, Alan Coopersmith)
90 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
91 to LOG_INFO, matching how we use this log level in practice
92 (fd.o #102686, Simon McVittie)
94 D-Bus 1.11.16 (2017-07-27)
97 The “south facing garden” release.
99 Build-time configuration changes:
101 • The Autotools build system now supports varying ${runstatedir}
102 independently of ${localstatedir}, if using an Autoconf version
103 that has that feature; version 2.70 will eventually have this, but
104 many Linux distributions add it to version 2.69 as a patch.
105 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
106 and runstatedir=/run. (fd.o #101569, Simon McVittie)
110 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
111 and dbus_message_iter_abandon_container_if_open() simplify the
112 single-exit-point ("goto out") style of resource cleanup. The API
113 documentation around DBusMessageIter and containers has also been
114 clarified. (fd.o #101568, Simon McVittie)
118 • Fix the implementation of re-enabling a timeout (again) so that its
119 countdown is always restarted as intended. (fd.o #95619,
122 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
123 available to all users on the system bus (fd.o #101700, Simon McVittie)
125 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
126 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
128 • dbus_message_iter_open_container() no longer leaks memory if it runs out
129 of memory. (fd.o #101568, Simon McVittie)
131 • dbus_message_append_args_valist() no longer leaks memory if given an
132 unsupported type. This situation is still considered to be a programming
133 error which needs to be corrected by the user of libdbus.
134 (fd.o #101568, Simon McVittie)
136 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
137 will no longer report that their arguments were invalid if they run out
138 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
140 • Ensure that tests fail if they would otherwise have tried to connect to
141 the real session bus (fd.o #101698, Simon McVittie)
143 • Make build-time tests cope with finding Python 3, but not Python 2
144 (fd.o #101716, Simon McVittie)
146 Internal changes relevant to dbus developers:
148 • DBusVariant is a new mechanism to copy single values from a message into
149 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
151 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
152 Logging an ERROR message does not make the process exit; the caller
153 is responsible for calling abort() or exit(), whichever is more appropriate.
154 (fd.o #101568, Simon McVittie)
156 • Better test coverage (fd.o #101568, Simon McVittie)
158 D-Bus 1.11.14 (2017-06-29)
161 The “irrational fear of bees” release.
165 • Expat >= 2.1.0 is always required
166 • libselinux >= 2.0.86 is required if SELinux support is enabled
167 • GLib >= 2.40 is required if full test coverage is enabled
169 Build-time configuration changes:
171 • We now use pkg-config to find libexpat in Autotools builds. This requires
172 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
173 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
174 itself cause compilation failures.
176 As with all pkg-config-based configure checks, you can use
177 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
178 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
179 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
182 (fd.o #69801, Simon McVittie)
184 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
185 is required due to the removal of explicit refcounting for SIDs.
186 (fd.o #100912, Laurent Bigonville)
190 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
191 as a side-effect of a sufficiently privileged process merely reading the
192 machine ID. It is no longer copied as a side-effect of reading.
193 Running dbus-uuidgen --ensure, which should be done after installing dbus,
194 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
195 former exists and the latter does not.
196 (fd.o #101257, Simon McVittie)
198 • The undocumented Verbose interface, and the GetAllMatchRules method on
199 the undocumented Stats interface, must now be used via the object path
200 /org/freedesktop/DBus. Previously, they existed on all object paths.
201 (fd.o #101257, Simon McVittie)
203 • AddMatch() with a match rule containing eavesdrop='true' will now fail
204 unless called by either the same user as the dbus-daemon, or Unix uid 0
205 (root), matching the restrictions applied to the newer BecomeMonitor()
206 method. On the session bus this has no practical effect. On the system
207 bus this will prevent certain configurations that already did not
208 work well in practice. (fd.o #101567, Simon McVittie)
212 • D-Bus Specification version 0.31
213 · Don't require implementation-specific search paths to be lowest
215 · Correct regex syntax for optionally-escaped bytes in addresses so it
216 includes hyphen-minus, forward slash and underscore as intended
217 · Describe all message bus methods in the same section
218 · Clarify the correct object path for method calls to the message bus
219 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
220 · Document that the message bus implements Introspectable, Peer and
222 · Add new Features and Interfaces properties for message bus
224 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
226 · Don't require eavesdrop='true' to be accepted from connections not
227 sufficiently privileged to use it successfully
228 · Formally deprecate eavesdropping in favour of BecomeMonitor
229 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
230 Simon McVittie, Tom Gundersen)
232 • Implement the Properties and Peer interfaces in dbus-daemon
233 (fd.o #101257, Simon McVittie)
235 • New function dbus_try_get_local_machine_id() is like
236 dbus_get_local_machine_id(), but returning a DBusError. Other code
237 that needs the machine ID will now report a recoverable error (instead
238 of logging to stderr and aborting) if no machine ID is available.
239 Generating a machine ID is still considered to be a required part of
240 installing dbus correctly. (fd.o #13194, Simon McVittie)
242 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
243 (fd.o #101315, Laurent Bigonville)
245 • Avoid deprecated API calls when using SELinux
246 (fd.o #100912, Laurent Bigonville)
248 • Switch a test from the deprecated g_test_trap_fork() to
249 g_test_trap_subprocess(), for Windows support and better robustness
250 on Unix (fd.o #101362, Simon McVittie)
252 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
253 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
254 This prevents the two files from going out of sync on stateless or live
255 images without needing to run dbus-uuidgen, and supports older D-Bus
256 implementations that do not necessarily read /etc/machine-id themselves.
257 (fd.o #101570, Simon McVittie)
259 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
260 abstract sockets. This is preferable when used with Linux containers.
261 (fd.o #101567, Simon McVittie)
265 • Fix a reference leak when blocking on a pending call on a connection
266 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
268 • Don't put timestamps in the Doxygen-generated documentation,
269 or hard-code the build directory into builds with embedded tests,
270 for reproducible builds (fd.o #100692, Simon McVittie)
272 • Fix some integration test issues (fd.o #100686, Simon McVittie)
274 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
276 • If we somehow get an autolaunch address with multiple semicolon-separated
277 components, and they don't work, don't invalidly "pile up" errors
278 (fd.o #101257, Simon McVittie)
282 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
283 (fd.o #100715, Simon McVittie)
285 D-Bus 1.11.12 (2017-04-07)
288 The “it's something humans do” release.
292 • The session dbus-daemon now supports transient .service files
293 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
294 service directories, this directory is not monitored with inotify
295 or similar, and the service files must be named exactly
296 ${bus_name}.service. (fd.o #99825, Simon McVittie)
298 • dbus can be configured with --enable-relocation when building with
299 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
300 to make the pkg-config metadata relocatable. This is useful for
301 non-standard prefixes, and in particular for Windows installations.
302 However, it is not recommended for system-wide installations into
303 /usr, because it interferes with pkg-config's ability to filter out
304 compiler default linker directories.
306 With Autotools, the default is --enable-relocation when building
307 for Windows or --disable-relocation otherwise. With CMake, the default
308 is -DDBUS_RELOCATABLE=ON.
310 (fd.o #99721; Ralf Habacker, Simon McVittie)
312 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
313 own FindDBus.cmake macros, whether dbus was compiled with Autotools
314 or with CMake. See the end of README.cmake for more information.
315 (fd.o #99721; Ralf Habacker, Simon McVittie)
319 • Always read service file directories in the intended order
320 (fd.o #99825, Simon McVittie)
322 • When tests are skipped, don't try to kill nonexistent process 0
323 (fd.o #99825, Simon McVittie)
325 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
327 • Fix a harmless read overflow and some memory leaks in a unit test
328 (fd.o #100568, Philip Withnall)
330 • Fix some typos in test code
331 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
333 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
334 in documentation (fd.o #99901, Philip Withnall)
336 • Fix and enable compiler warnings related to -Wswitch
337 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
339 • Fix writing off the end of a fd_set when testing with valgrind
340 (fd.o #99839, Philip Withnall)
342 D-Bus 1.11.10 (2017-02-16)
345 The “purple hair gives you telekinesis?” release.
349 • AppArmor support requires at least libapparmor 2.8.95, reduced
350 from 2.10 in previous versions. One test requires 2.10 and is
351 skipped if building with an older version.
355 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
356 stable and Debian testing in addition to the older Ubuntu that is
357 the default (fd.o #98889, Simon McVittie)
359 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
361 • Silence many -Wswitch-enum and -Wswitch-default warnings
362 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
364 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
365 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
367 • Install pkg-config metadata on Unix even if building with CMake
368 (fd.o #99752, Ralf Habacker)
370 • Exclude auth mechanisms from REJECTED message if they are supported
371 in the code but but configured to be disallowed (fd.o #99621,
376 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
377 allow an attacker to overwrite a file named "nonce", in a directory
378 that the user running dbus-daemon can write, with a random value
379 known only to the user running dbus-daemon. This is unlikely to be
380 exploitable in practice, particularly since the nonce-tcp transport
381 is really only useful on Windows.
383 On Unix systems we strongly recommend using only the unix: and systemd:
384 transports, together with EXTERNAL authentication. These are the only
385 transports and authentication mechanisms enabled by default.
387 (fd.o #99828, Simon McVittie)
389 • Avoid symlink attacks in the "embedded tests", which are not enabled
390 by default and should never be enabled in production builds of dbus.
391 (fd.o #99828, Simon McVittie)
393 • Fix the implementation of re-enabling a timeout so that its
394 countdown is restarted as intended, instead of continually
395 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
397 • When receiving a message with file descriptors, do not start reading
398 the beginning of the next message, so that only one such message
399 is processed at a time. In conjunction with the fix for #95619
400 this means that processes sending many file descriptors, such as
401 systemd-logind on a system that receives very rapid ssh connections,
402 are not treated as abusive and kicked off the bus. Revert the previous
403 workaround that special-cased uid 0.
404 (fd.o #95263, LP#1591411; Simon McVittie)
406 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
407 for Windows with CMake (fd.o #99586, Ralf Habacker)
409 • Do not set Unix-specific variables when targeting Windows
410 (fd.o #99586, Ralf Habacker)
412 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
413 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
415 • Use relative install locations in CMake on Unix to respect DESTDIR,
416 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
418 • Install dbus-arch-deps.h correctly when using CMake
419 (fd.o #99586, #99721; Ralf Habacker)
421 • Improve argument validation for `dbus-test-tool spam`
422 (ffd.o #99693, Coverity #54759; Philip Withnall)
424 • Don't shift by a negative integer if a hash table becomes monstrously
425 large (fd.o #99641, Coverity #54682; Philip Withnall)
427 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
428 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
430 • Remove an unnecessary NULL check
431 (fd.o #99642, Coverity #141062; Philip Withnall)
433 • Improve error handling in unit tests and dbus-send
434 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
435 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,
436 #54710, #54711, #54714, #54715, #54718, #54721, #54724, #54726,
437 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
439 • Do not print verbose messages' timestamps to stderr if the actual message
440 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
442 D-Bus 1.11.8 (2016-11-28)
445 The “panics in the face of breakfast foods” release.
447 Build-time configuration:
449 • The new --enable-debug configure option provides an easy way to
450 enable debug symbols, disable optimization and/or enable profiling.
452 • The --enable-compile-warnings configure option can be used to control
455 • The --disable-compiler-optimisations configure option is no longer
456 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
460 • D-Bus Specification version 0.30
461 · Define the jargon term "activation" more clearly
462 · Define the jargon term "auto-starting", which is one form of activation
463 · Document the optional SystemdService key in service files
464 · Use versioned interface and bus names in most examples
465 · Clarify intended behaviour of Properties.GetAll
466 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
468 • Fix and enable a lot of compiler warnings to improve future code
469 quality. This might incidentally also fix some environment variable
471 · In particular, printf-style functions in the libdbus API are now annotated
472 with __attribute__((__format__(__printf__, *, *))) when compiling with
473 gcc or clang. This might make printf bugs in other software visible
475 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
476 Thomas Zimmermann, Simon McVittie)
478 • When running with AppArmor mediation (for example using Ubuntu's patched
479 Linux kernel), clients can no longer auto-start services unless they would
480 have been able to send the auto-starting message to the service after it
481 starts. StartServiceByName() is unaffected, and continues to be allowed by
482 default in AppArmor's <abstractions/dbus-strict> and
483 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
487 • Work around an undesired effect of the fix for CVE-2014-3637
488 (fd.o #80559), in which processes that frequently send fds, such as
489 logind during a flood of new PAM sessions, can get disconnected for
490 continuously having at least one fd "in flight" for too long;
491 dbus-daemon interprets that as a potential denial of service attack.
492 The workaround is to disable that check for uid 0 process such as
493 logind, with a message in the system log. The bug remains open while
494 we look for a more general solution.
495 (fd.o #95263, LP#1591411; Simon McVittie)
497 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
498 was disabled at compile time. That test is not expected to work
499 in that configuration. (fd.o #98665, Simon McVittie)
501 D-Bus 1.11.6 (2016-10-10)
504 The “darkly whimsical” release.
508 • Do not treat ActivationFailure message received from root-owned systemd
509 name as a format string. In principle this is a security vulnerability,
510 but we do not believe it is exploitable in practice, because only
511 privileged processes can own the org.freedesktop.systemd1 bus name, and
512 systemd does not appear to send activation failures that contain "%".
514 Please note that this probably *was* exploitable in dbus versions
515 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
516 the time was only thought to be a denial of service vulnerability
517 (CVE-2015-0245). If you are still running one of those versions,
518 patch or upgrade immediately.
520 (fd.o #98157, Simon McVittie)
524 • D-Bus Specification version 0.29
525 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
526 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
528 • Log to syslog when we exceed various anti-DoS limits, and add test
529 coverage for them (fd.o #86442, Simon McVittie)
531 • Improve syslog handling so that _dbus_warn() and similar warnings
532 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
533 and log to syslog (instead of /dev/null) when dbus-daemon is started by
534 dbus-launch. (fd.o #97009, Simon McVittie)
536 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
537 (fd.o #89011, Philip Withnall)
539 • When logging messages about service activation, mention which peer
540 requested the activation (fd.o #68212, Philip Withnall)
542 • On Linux, mention the LSM label (if available) whenever we print
543 debug information about a peer (fd.o #68212, Philip Withnall)
547 • Harden dbus-daemon against malicious or incorrect ActivationFailure

550 (fd.o #98157, Simon McVittie)
552 • Avoid undefined behaviour when setting reply serial number without going
553 via union DBusBasicValue (fd.o #98035, Marc Mutz)
555 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,

560 D-Bus 1.11.4 (2016-08-15)
563 The “copper pickaxe” release.

588 (fd.o #95191, Ralf Habacker)
590 • Print timestamps and thread IDs in verbose messages
591 (fd.o #95191, Ralf Habacker)
593 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
594 pointing to /dev/null (fd.o #97008, Simon McVittie)
596 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
597 (fd.o #88922, Thomas Zimmermann)
601 • On Windows, fix a memory leak in replacing the installation prefix
602 (fd.o #95191, Ralf Habacker)
604 • On Linux, when dbus-daemon is run with reduced susceptibility to the
605 OOM killer (typically via systemd), do not let child processes inherit
606 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
608 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
609 even if a parent process incorrectly starts them with stdin, stdout
610 and/or stderr closed (fd.o #97008, Simon McVittie)
612 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
613 contains a semicolon (fd.o #94746, Thiago Macieira)

621 • In tests that exercise correct handling of crashing D-Bus services,
622 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
624 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
626 • In tests, add an invalid DBusAuthState to avoid undefined behaviour

644 • During unit tests, reduce the amount we write to the system log
645 (fd.o #97009, Simon McVittie)
647 D-Bus 1.11.2 (2016-03-07)
650 The “pneumatic drill vs. Iron Maiden” release.
654 • Enable "large file support" on systems where it exists: dbus-daemon
655 is not expected to open large files, but it might need to stat files
656 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
658 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
659 which might result in a pedantic C compiler not copying the entire contents
660 of a DBusMessageIter; statically assert that this is not an ABI change
661 in practice (fd.o #94136, Simon McVittie)
663 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
664 (fd.o #94244, Dmitri Iouchtchenko)
666 • Correctly report test failures in C tests from run-test.sh
667 (fd.o #93379; amit tewari, Simon McVittie)
669 • When tests are enabled, run all the marshal-validate tests, not just
670 the even-numbered ones (fd.o #93908, Nick Lewycky)
672 • Correct the expected error from one marshal-validate test, which was
673 previously not run due to the above bug (fd.o #93908, Simon McVittie)
675 • Fix compilation under CMake when embedded tests are disabled
676 (fd.o #94094, eric.hyer)
680 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
681 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
683 • When building with CMake, use the same gcc/clang warnings as under Autotools,
684 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
686 • test/name-test: make C tests produce TAP output and run them directly, not
687 via run-test.sh (fd.o #92899, Simon McVittie)

690 under Wine even if binfmt_misc support is not available
691 (fd.o #88966, Ralf Habacker)
693 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
694 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
696 • Factor out some functions that will be needed in future for a Windows
697 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
699 D-Bus 1.11.0 (2015-12-02)
702 The “peppermint deer” release.
706 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
707 C99 constants such as PRId64 and PRIu64.
711 • D-Bus Specification version 0.27
712 · Specify that services should not reply if NO_REPLY_EXPECTED was used
713 (fd.o #75749, Lars Uebernickel)
715 • Add a script to do continuous-integration builds, and metadata to run it
716 on travis-ci.org. To use this, clone the dbus git repository on GitHub
717 and set it up with travis-ci.org; the only special setting needed is
718 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
720 • If dbus-daemon is run with --systemd-activation, do not require
721 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
725 • Re-order dbus-daemon startup so that on SELinux systems, the thread
726 that reads AVC notifications retains the ability to write to the
727 audit log (fd.o #92832, Laurent Bigonville)
729 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
731 • When using the Monitoring interface, match messages' destinations
732 (fd.o #92074, Simon McVittie)
734 • On Linux with systemd, stop installing a reference to the obsolete

742 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
744 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
746 D-Bus 1.10.6 (2015-12-01)
749 The “marzipan beetles” release.
753 • On Unix when running tests as root, don't assert that root and
754 the dbus-daemon user can still call UpdateActivationEnvironment;
755 assert that those privileged users can call BecomeMonitor instead
756 (fd.o #93036, Simon McVittie)
758 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
761 • On Windows Autotools builds, don't run tests that rely on
762 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
764 D-Bus 1.10.4 (2015-11-17)
767 The “Frostburn Canyon” release.
771 • GetConnectionCredentials, GetConnectionUnixUser and
772 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
773 will now return details of the dbus-daemon itself. This is required
774 to be able to call SetEnvironment on systemd.
775 (fd.o #92857, Jan Alexander Steffens)
779 • Make UpdateActivationEnvironment always fail with AccessDenied on the
780 system bus. Previously, it was possible to configure it so root could
781 call it, but the environment variables were not actually used,
782 because the launch helper would discard them.
783 (fd.o #92857, Jan Alexander Steffens)
785 • On Unix with --systemd-activation on a user bus, make
786 UpdateActivationEnvironment pass on its arguments to systemd's
787 SetEnvironment method, solving inconsistency between the environments
788 used for traditional activation and systemd user-service activation.
789 (fd.o #92857, Jan Alexander Steffens)
791 • On Windows, don't crash if <syslog/> or --syslog is used
792 (fd.o #92538, Ralf Habacker)
794 • On Windows, fix a memory leak when setting a DBusError from a Windows
795 error (fd.o #92721, Ralf Habacker)
797 • On Windows, don't go into infinite recursion if we abort the process
798 with backtraces enabled (fd.o #92721, Ralf Habacker)
800 • Fix various failing tests, variously on Windows and cross-platform:
801 · don't test system.conf features (users, groups) that only make sense
802 on the system bus, which is not supported on Windows
803 · don't call _dbus_warn() when we skip a test, since it is fatal
804 · fix computation of expected <standard_session_servicedirs/>
805 · when running TAP tests, translate newlines to Unix format, fixing
806 cross-compiled tests under Wine on Linux
807 · don't stress-test refcounting under Wine, where it's really slow
808 · stop assuming that a message looped-back to the test will be received
810 · skip some system bus tests on Windows since they make no sense there
811 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
813 D-Bus 1.10.2 (2015-10-26)
816 The “worst pies in London” release.
820 • Correct error handling for activation: if there are multiple attempts
821 to activate the same service and it fails immediately, the first attempt
822 would get the correct reply, but the rest would time out. We now send
823 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
825 • If BecomeMonitor is called with a syntactically invalid match rule,
826 don't crash with an assertion failure, fixing a regression in 1.9.10.
827 This was not exploitable as a denial of service, because the check
828 for a privileged user is done first. (fd.o #92298, Simon McVittie)
830 • On Linux with --enable-user-session, add the bus address to the
831 environment of systemd services for better backwards compatibility
832 (fd.o #92612, Jan Alexander Steffens)
834 • On Windows, fix the logic for replacing the installation prefix
835 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
837 • On Windows, if installed in the conventional layout with ${prefix}/etc
838 and ${prefix}/share, use relative paths between bus configuration files
839 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
841 • Make more of the regression tests pass in Windows builds (fd.o #92538,
844 D-Bus 1.10.0 (2015-08-25)
849 This is a new stable branch, recommended for use in OS distributions.
853 • distribute test/tap-test.sh.in, even if the tarball was built without
854 tests enabled (fd.o #91684, Simon McVittie)
855 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
857 Summary of major changes since 1.8.0:
859 • The basic setup for the well-known system and session buses is
860 now done in read-only files in ${datadir} (normally /usr/share).
861 See the NEWS entry for 1.9.18 for details.
863 • AppArmor integration has been merged, with features similar to the
864 pre-existing SELinux integration. It is mostly compatible with the
865 patches previously shipped by Ubuntu, with one significant change:
866 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
867 by GetConnectionCredentials and was not included.
869 • The --enable-user-session configure option can be enabled
870 by OS integrators intending to use systemd to provide a session bus
871 per user (in effect, treating all concurrent graphical and non-graphical
872 login sessions as one large session).
874 • The new listenable address mode "unix:runtime=yes" listens on
875 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
876 user session. libdbus and "dbus-launch --autolaunch" will connect to
877 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
880 • All executables are now dynamically linked to libdbus-1.
881 Previously, some executables, most notably dbus-daemon, were statically
882 linked to a specially-compiled variant of libdbus. This results in
883 various private functions in the _dbus namespace being exposed by the
884 shared library. These are not API, and must not be used outside
885 the dbus source tree.
887 • On platforms with ELF symbol versioning, all public symbols
888 are versioned LIBDBUS_1_3.
892 • org.freedesktop.DBus.GetConnectionCredentials returns
893 LinuxSecurityLabel where supported
894 • org.freedesktop.DBus.Monitoring interface (privileged)
895 · BecomeMonitor method supersedes match rules with eavesdrop=true,
896 which are now deprecated
897 • org.freedesktop.DBus.Stats interface (semi-privileged)
898 · now enabled by default
899 · new GetAllMatchRules method
900 • org.freedesktop.DBus.Verbose interface (not normally compiled)
901 · toggles the effect of DBUS_VERBOSE
906 • dbus-update-activation-environment
908 New optional dependencies:
910 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
911 • Complete documentation requires Ducktype and yelp-tools
912 • Full test coverage requires GLib 2.36 and PyGI
913 • AppArmor integration requires libapparmor and optionally libaudit
915 Dependencies removed:
919 D-Bus 1.9.20 (2015-08-06)
922 The “Remember Tomorrow” release.
924 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
929 • Don't second-guess what the ABI of poll() is, allowing it to be used
930 on Integrity RTOS and other unusual platforms (fd.o #90314;
931 Rolland Dudemaine, Simon McVittie)
933 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
934 both enabled (fd.o #89225, Simon McVittie)
936 • Log audit events for AppArmor/SELinux policy violations whenever
937 we have CAP_AUDIT_WRITE, even if not the system bus
938 (fd.o #83856, Laurent Bigonville)
940 D-Bus 1.9.18 (2015-07-21)
943 The “Pirate Elite” release.
945 Configuration changes:
947 • The basic setup for the well-known system and session buses is now done
948 in read-only files in ${datadir}, moving a step closer to systems
949 that can operate with an empty /etc directory. In increasing order
952 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
953 the default message policies.
954 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
955 dbus still installs a trivial version of each, for documentation
956 purposes; putting configuration directives in these files is deprecated.
957 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
958 to install "drop-in" configuration snippets (any packages
959 using those directories should explicitly depend on at least this
961 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
962 or third-party software to install "drop-in" configuration snippets
963 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
966 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
967 and "s*" refers to either system or session as appropriate.
969 (fd.o #89280, Dimitri John Ledkov)
973 • Fix a memory leak when GetConnectionCredentials() succeeds
974 (fd.o #91008, Jacek Bukarewicz)
976 • Ensure that dbus-monitor does not reply to messages intended for others,
977 resulting in its own disconnection (fd.o #90952, Simon McVittie)
979 D-Bus 1.9.16 (2015-05-14)
982 The “titanium barns” release.
986 • Automake 1.13 is now required when compiling from git or modifying
991 • On Unix platforms, change the default configuration for the session bus
992 to only allow EXTERNAL authentication (secure kernel-mediated
993 credentials-passing), as was already done for the system bus.
995 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
996 unpredictable pseudo-random numbers.
998 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
999 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1000 NFS or similar, you will need to reconfigure the session bus to accept
1001 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1004 (fd.o #90414, Simon McVittie)
1006 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1007 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1008 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1009 occurs, instead of silently falling back to low-entropy pseudorandom
1010 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1014 • Add dbus_message_iter_get_element_count()
1015 (fd.o #30350; Christian Dywan, Simon McVittie)
1017 • Introduce new internal DBusSocket and DBusPollable types so we can
1018 stop treating the Windows SOCKET type as if it was int. DBusSocket
1019 is specifically a socket, cross-platform. DBusPollable is whatever
1020 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1021 (fd.o #89444; Ralf Habacker, Simon McVittie)
1023 • All regression tests now output TAP <https://testanything.org/>
1024 (fd.o #89846, Simon McVittie)
1026 • Internal APIs consistently use signed values for timestamps
1027 (fd.o #18494, Peter McCurdy)
1029 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1030 (fd.o #88812, Simon McVittie)
1032 • Clean up a lot of compiler warnings
1033 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1037 • Add locking to DBusCounter's reference count and notify function
1038 (fd.o #89297, Adrian Szyndela)
1040 • Ensure that DBusTransport's reference count is protected by the
1041 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1043 • Correctly release DBusServer mutex before early-return if we run out
1044 of memory while copying authentication mechanisms (fd.o #90021,
1047 • Make dbus-test-tool and dbus-update-activation-environment portable
1048 to Windows (fd.o #90089, Ralf Habacker)
1050 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1051 Ralf Habacker, Simon McVittie)
1053 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1056 • Clean up some memory and fd leaks in test code and tools
1057 (fd.o #90021, Ralf Habacker)
1059 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1060 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1062 • CMake generates a versioned shared library even if the revision is 0,
1063 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1065 D-Bus 1.9.14 (2015-03-02)
1068 The “don't stand in the poison cloud” release.
1072 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1073 were previously linked to a static version of libdbus.
1075 • The tests no longer require dbus-glib in order to exercise the libdbus
1076 shared library; they are always linked to libdbus now.
1078 Build-time configuration:
1080 • The new --enable-user-session option, off by default, can be enabled
1081 by OS integrators intending to use systemd to provide a session bus
1082 per user (in effect, treating all concurrent graphical and non-graphical
1083 login sessions as one large session)
1087 • All executables are now linked dynamically to libdbus.
1088 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1090 • On platforms that support them (GNU libc and possibly others),
1091 libdbus now has versioned symbols for its public API.
1092 All public symbols (visible in the header files) are currently
1093 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1094 dbus_internal have a version that changes with each release, and
1095 must not be used by applications. (also fd.o #83115)
1097 • New listenable address mode "unix:runtime=yes" which listens on
1098 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1099 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1101 • Add optional systemd units for a per-user bus listening on
1102 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1104 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1105 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1108 • New dbus-update-activation-environment tool uploads environment
1109 variables to "dbus-daemon --session" and optionally "systemd --user",
1110 primarily as a way to keep the per-user bus compatible with
1111 distributions' existing X11 login scripts (also fd.o #61301)
1113 • <includedir/> elements in dbus-daemon configuration are now silently
1114 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1116 • Add microsecond-resolution timestamps to the default output of
1117 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1121 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1122 (fd.o #89222, Simon McVittie)
1124 D-Bus 1.9.12 (2015-02-19)
1127 The “monster lasagna” release.
1131 • Ducktype and yelp-tools are now required to build complete documentation
1132 (they are optional for normal builds).
1136 • D-Bus Specification version 0.26
1137 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1138 · document the BecomeMonitor method
1140 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1141 (fd.o #89041; Tyler Hicks, Simon McVittie)
1143 • On Linux, add support for AppArmor mediation of message sending and
1144 receiving and name ownership (paralleling existing SELinux mediation
1145 support), and eavesdropping (a new check, currently AppArmor-specific)
1146 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1148 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1149 that have printable ASCII contents; we previously only did this for
1150 unterminated bytestrings (fd.o #89109, Simon McVittie)
1152 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1154 • On Windows, add WindowsSID to GetConnectionCredentials
1155 (fd.o #54445, Ralf Habacker)
1157 • Improve clarity of dbus-monitor --profile output and add more columns
1158 (fd.o #89165, Ralf Habacker)
1160 • Add a man page for dbus-test-tool, and build it under CMake as well
1161 as Autotools (fd.o#89086, Simon McVittie)
1163 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1164 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1165 (fd.o #88896, Ralf Habacker)
1169 • Reduce the number of file descriptors used in the fd-passing test,
1170 avoiding failure under the default Linux fd limit, and automatically
1171 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1173 D-Bus 1.9.10 (2015-02-09)
1176 The “sad cyborgs” release.
1178 Security fixes merged from 1.8.16:
1180 • Do not allow non-uid-0 processes to send forged ActivationFailure
1181 messages. On Linux systems with systemd activation, this would
1182 allow a local denial of service: unprivileged processes could
1183 flood the bus with these forged messages, winning the race with
1184 the actual service activation and causing an error reply
1185 to be sent back when service auto-activation was requested.
1186 This does not prevent the real service from being started,
1187 so the attack only works while the real service is not running.
1188 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1192 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1193 similar tools receive messages without altering the security properties
1194 of the system bus, by calling the new BecomeMonitor method on a
1195 private connection. This bypasses the normal <allow> and <deny> rules
1196 entirely, so to preserve normal message-privacy assumptions, only root
1197 is allowed to do this on the system bus. Restricted environments,
1198 such as Linux with LSMs, should lock down access to the Monitoring
1199 interface. (fd.o #46787, Simon McVittie)
1201 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1202 dbus-daemon supports it and access permissions allow it.
1203 It still supports the previous approach ("eavesdropping" match rules)
1204 for compatibility with older bus daemons. (fd.o #46787, Simon)
1206 • dbus-monitor can now log the message stream as binary data for later
1207 analysis, with either no extra framing beyond the normal D-Bus headers,
1208 or libpcap-compatible framing treating each D-Bus message
1209 as a captured packet. (fd.o #46787, Simon)
1213 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1215 • On Unix, forcibly terminate regression tests after 60 seconds to
1216 prevent them from blocking continuous integration frameworks
1217 (fd.o #46787, Simon)
1219 D-Bus 1.9.8 (2015-02-03)
1222 The “all the types of precipitation” release.
1226 • full test coverage now requires GLib 2.36
1227 • full test coverage now requires PyGI (PyGObject 3,
1228 "import gi.repository.GObject") instead of the
1229 obsolete PyGObject 2 ("import gobject")
1233 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1235 • better regression test coverage, including systemd activation
1236 (fd.o #57952, #88810; Simon McVittie)
1240 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1241 turned off (fd.o #88808, Simon McVittie)
1243 • TCP sockets on Windows no longer fail to listen approximately 1 time
1244 in 256, caused by a logic error that should have always made it fail but
1245 was mitigated by incorrect endianness for the port number
1246 (fd.o #87999, Ralf Habacker)
1248 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1250 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1251 previous 64, completing a previous fix which only worked under
1252 Autotools (fd.o #71297, Ralf Habacker)
1254 • on Windows, if the IP family is unspecified only use IPv4,
1255 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1257 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1259 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1261 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1264 D-Bus 1.9.6 (2015-01-05)
1267 The “I do have a bread knife” release.
1271 • Do not allow calls to UpdateActivationEnvironment from uids other than
1272 the uid of the dbus-daemon. If a system service installs unsafe
1273 security policy rules that allow arbitrary method calls
1274 (such as CVE-2014-8148) then this prevents memory consumption and
1275 possible privilege escalation via UpdateActivationEnvironment.
1277 We believe that in practice, privilege escalation here is avoided
1278 by dbus-daemon-launch-helper sanitizing its environment; but
1279 it seems better to be safe.
1281 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1282 on object paths other than /org/freedesktop/DBus. Some system services
1283 install unsafe security policy rules that allow arbitrary method calls
1284 to any destination, method and interface with a specified object path;
1285 while less bad than allowing arbitrary method calls, these security
1286 policies are still harmful, since dbus-daemon normally offers the
1287 same API on all object paths and other system services might behave
1292 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1293 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1295 D-Bus 1.9.4 (2014-11-24)
1298 The “extra-sturdy caramel” release.
1302 • Partially revert the CVE-2014-3639 patch by increasing the default
1303 authentication timeout on the system bus from 5 seconds back to 30
1304 seconds, since this has been reported to cause boot regressions for
1305 some users, mostly with parallel boot (systemd) on slower hardware.
1307 On fast systems where local users are considered particularly hostile,
1308 administrators can return to the 5 second timeout (or any other value
1309 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1312 <limit name="auth_timeout">5000</limit>
1315 (fd.o #86431, Simon McVittie)
1317 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1318 (fd.o #86431, Simon McVittie)
1320 • Send back an AccessDenied error if the addressed recipient is not allowed
1321 to receive a message (and in builds with assertions enabled, don't
1322 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1324 D-Bus 1.9.2 (2014-11-10)
1327 The “structurally unsound flapjack” release.
1331 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1332 so that CVE-2014-3636 part A cannot exhaust the system bus'
1333 file descriptors, completing the incomplete fix in 1.8.8.
1334 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1338 • D-Bus Specification version 0.25
1339 · new value 'const' for EmitsChangedSignal annotation
1340 (fd.o #72958, Lennart Poettering)
1341 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1342 (fd.o #83449; Lennart Poettering, Simon McVittie)
1343 · annotate table of types with reserved/basic/container, and for
1344 basic types, fixed/string-like
1345 · clarify arbitrary limits by quoting them in mebibytes
1347 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1348 (fd.o #83449, Simon McVittie)
1350 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1351 useful for debugging and performance testing:
1352 · dbus-test-tool spam: send repeated messages
1353 · dbus-test-tool echo: send an empty reply for all method calls
1354 · dbus-test-tool black-hole: do not reply to method calls
1355 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1357 • Add support for process ID in credentials-passing on NetBSD
1358 (fd.o #69702, Patrick Welche)
1360 • Add an example script to find potentially undesired match rules
1361 (fd.o #84598, Alban Crequy)
1363 • Document the central assumption that makes our use of credentials-passing
1364 secure (fd.o #83499, Simon McVittie)
1366 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1367 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1372 • Use a less confusing NoReply message when disconnected with a reply pending
1373 (fd.o #76112, Simon McVittie)
1375 • Make the .pc file relocatable by letting pkg-config do all variable
1376 expansion itself (fd.o #75858, Руслан Ижбулатов)
1378 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1379 (fd.o #85563, Patrick Welche)
1381 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1383 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1384 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1386 • Do not fail the tests if a parent process has leaked non-close-on-exec
1387 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1389 • Do not fail the tests on Unix platforms with incomplete
1390 credentials-passing support, but do fail if we can't pass credentials
1391 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1392 (fd.o #69702, Simon McVittie)
1394 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1395 when building with cmake, and expand test coverage there
1396 (fd.o #73689; Ralf Habacker, Simon McVittie)
1398 D-Bus 1.9.0 (2014-10-01)
1401 The “tiered cheeses” release.
1405 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1406 requires either the libsystemd or libsd-daemon shared library, dropping the
1407 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1409 Build-time configuration changes:
1411 • The Stats interface is now enabled by default, and locked-down to
1412 root-only on the system bus. Configure with --disable-stats
1413 to disable it altogether on memory- or disk-constrained systems,
1414 or see ${docdir}/examples/ to open it up to non-root users on the
1415 system bus or restrict access on the session bus.
1416 (fd.o #80759; Simon McVittie, Alban Crequy)
1418 • The CMake build system now builds the same shared library name as Autotools
1419 on at least Linux and Windows:
1420 - on Linux (and perhaps other Unix platforms), it previously built
1421 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1422 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1423 - on Windows, it previously built either libdbus-1.dll (release) or
1424 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1425 libdbus-1.dll for compatibility with older applications.
1426 (fd.o #74117, Ralf Habacker)
1430 • D-Bus Specification version 0.24
1431 · document how to quote match rules (fd.o #24307, Simon McVittie)
1432 · explicitly say that most message types never expect a reply
1433 regardles of whether they have NO_REPLY_EXPECTED
1434 (fd.o #75749, Simon McVittie)
1436 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
1437 initial latency (fd.o #75544, Matt Hoosier)
1439 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
1440 (fd.o #69702, Patrick Welche)
1442 • in dbus-monitor, print more information about file descriptors
1443 (fd.o #80603, Alban Crequy)
1445 • do not install system bus configuration if built for Windows
1446 (fd.o #83583; Ralf Habacker, Simon McVittie)
1448 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
1450 • Add a regression test for file descriptor passing (fd.o #83622,
1455 • fix an incorrect error message if a Unix socket path is too long
1456 (fd.o #73887, Antoine Jacoutot)
1458 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
1459 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
1461 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
1462 in ps(1) (fd.o #69716, Chengwei Yang)
1464 • avoid calling poll() with timeout < -1, which is considered invalid
1465 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
1467 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
1468 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
1469 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
1471 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
1473 • Documentation improvements
1474 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
1476 • in dbus-monitor, do not leak file descriptors that we have monitored
1477 (fd.o #80603, Alban Crequy)
1479 • Set the close-on-exec flag for the inotify file descriptor, even
1480 if built with CMake or older libc (fd.o #73689, Simon McVittie)
1482 • Remove some LGPL code from the Windows dbus-daemon
1483 (fd.o #57272, Ralf Habacker)
1485 D-Bus 1.8.8 (2014-09-16)
1488 The "smashy smashy egg man" release.
1492 • Do not accept an extra fd in the padding of a cmsg message, which
1493 could lead to a 4-byte heap buffer overrun.
1494 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1496 • Reduce default for maximum Unix file descriptors passed per message
1497 from 1024 to 16, preventing a uid with the default maximum number of
1498 connections from exhausting the system bus' file descriptors under
1499 Linux's default rlimit. Distributors or system administrators with a
1500 more restrictive fd limit may wish to reduce these limits further.
1502 Additionally, on Linux this prevents a second denial of service
1503 in which the dbus-daemon can be made to exceed the maximum number
1504 of fds per sendmsg() and disconnect the process that would have
1506 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1508 • Disconnect connections that still have a fd pending unmarshalling after
1509 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1510 removing the possibility of creating an abusive connection that cannot be
1511 disconnected by setting up a circular reference to a connection's
1513 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1515 • Reduce default for maximum pending replies per connection from 8192 to 128,
1516 mitigating an algorithmic complexity denial-of-service attack
1517 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1519 • Reduce default for authentication timeout on the system bus from
1520 30 seconds to 5 seconds, avoiding denial of service by using up
1521 all unauthenticated connection slots; and when all unauthenticated
1522 connection slots are used up, make new connection attempts block
1523 instead of disconnecting them.
1524 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1528 • Check for libsystemd from systemd >= 209, falling back to
1529 the older separate libraries if not found (Umut Tezduyar Lindskog,
1532 • On Linux, use prctl() to disable core dumps from a test executable
1533 that deliberately raises SIGSEGV to test dbus-daemon's handling
1534 of that condition (fd.o #83772, Simon McVittie)
1536 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
1539 • Improve documentation for running tests on Windows (fd.o #41252,
1542 D-Bus 1.8.6 (2014-06-02)
1547 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1548 the message. This prevents an attack in which a malicious client can
1549 make dbus-daemon disconnect a system service, which is a local
1551 (fd.o #80163, CVE-2014-3532; Alban Crequy)
1553 • Track remaining Unix file descriptors correctly when more than one
1554 message in quick succession contains fds. This prevents another attack
1555 in which a malicious client can make dbus-daemon disconnect a system
1557 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
1558 Simon McVittie, Alban Crequy)
1562 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
1563 attach to a session, kill the dbus-daemon as intended
1564 (fd.o #74698, Роман Донченко)
1566 D-Bus 1.8.4 (2014-06-10)
1571 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1572 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1573 Additionally, in highly unusual environments the same flaw could lead to
1574 a side channel between processes that should not be able to communicate.
1575 (CVE-2014-3477, fd.o #78979)
1577 D-Bus 1.8.2 (2014-04-30)
1580 The “nobody wants red” release.
1584 • in the CMake build system, add some hints for Linux users cross-compiling
1585 Windows D-Bus binaries to be able to run tests under Wine
1586 (fd.o #41252, Ralf Habacker)
1588 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
1592 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
1593 to /var/lib/dbus/machine-id instead of generating an entirely new ID
1594 (fd.o #77941, Simon McVittie)
1596 • if dbus-launch receives an X error very quickly, do not kill
1597 unrelated processes (fd.o #74698, Роман Донченко)
1599 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
1600 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
1602 • cope with \r\n newlines in regression tests, since on Windows,
1603 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
1605 D-Bus 1.8.0 (2014-01-20)
1608 The “Wolverine distrusts my printer” release.
1610 This starts a new stable branch. The 1.6.x branch is now considered to be
1611 outdated, and will only receive fixes for serious bugs such as security
1612 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1613 are unlikely to get any more releases, but if distributors still need to
1614 support them, please share security patches via upstream.
1616 Summary of changes since 1.6.x:
1618 • libdbus always behaves as if dbus_threads_init_default() had been called
1619 (thread-safety by default)
1620 • new dbus-run-session tool, replacing certain misuses of dbus-launch
1621 • dbus-monitor can talk to outdated versions of dbus-daemon again
1622 • new org.freedesktop.DBus.GetConnectionCredentials method
1623 • GetConnectionUnixProcessID also works correctly on Windows, returning
1624 the Windows process ID
1625 • GetConnectionWindowsSID returns the correct SID on Windows
1626 • expat is required, libxml2 can no longer be used as a substitute
1627 • the userDB cache is required, and cannot be disabled
1628 • a 64-bit integer type (either int, long, long long or _int64) is required
1629 • better systemd-journald integration on Linux
1630 • fixed long-standing fd and array leaks when failing to parse a message
1631 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
1632 when using certain object-path allocation patterns, notably in Avahi
1633 • better defaults for Windows support
1634 • better CMake support
1635 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
1636 • the source language for the man pages is now Docbook XML
1638 Enhancements since 1.7.10:
1640 • Enhance the CMake build system to check for GLib and compile/run
1641 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
1645 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
1648 • fix compilation of systemd journal support on older systemd versions where
1649 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
1651 • fix compilation on older MSVC versions by including stdlib.h
1652 (fd.o #73455, Ralf Habacker)
1654 • Allow <allow_anonymous/> to appear in an included configuration file
1655 (fd.o #73475, Matt Hoosier)
1657 Test behaviour changes since 1.7.10:
1659 • If the tests crash with an assertion failure, they no longer default to
1660 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
1661 environment if you want the old behaviour.
1663 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
1664 can be run with an external dbus-daemon by setting
1665 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
1666 an unusually-configured dbus-daemon are skipped.
1668 D-Bus 1.7.10 (2014-01-06)
1671 The “weighted companion cube” release.
1673 This is a release candidate for D-Bus 1.8.
1675 D-Bus Specification 0.23:

1691 • don't install systemd units if --disable-systemd is given
1692 (fd.o #71818, Chengwei Yang)
1696 • don't leak memory on out-of-memory while listing activatable or
1697 active services (fd.o #71526, Radoslaw Pajak)
1699 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
1701 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
1703 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
1704 and DBUS__SEND_MSG are numerically equal to their values in the
1705 reference policy (fd.o #88719, osmond sun)
1707 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
1708 (fd.o #71366, Matt Fischer)
1710 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
1711 winsock2.h (fd.o #71405, Matt Fischer)
1713 • do not return failure from _dbus_read_nonce() with no error set,
1714 preventing a potential crash (fd.o #72298, Chengwei Yang)
1716 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
1717 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
1719 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
1720 which doesn't do anything anyway on at least Linux and FreeBSD
1721 (fd.o #69492, Simon McVittie)
1723 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
1724 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
1725 for credentials more correctly (fd.o #69492, Simon McVittie)
1727 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
1728 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
1731 • refresh cached policy rules for existing connections when bus
1732 configuration changes (fd.o #39463, Chengwei Yang)
1734 D-Bus 1.7.8 (2013-11-01)
1737 The “extreme hills” release.
1741 • If systemd support is enabled, libsystemd-journal is now required.
1745 • When activating a non-systemd service under systemd, annotate its
1746 stdout/stderr with its bus name in the Journal. Known limitation:
1747 because the socket is opened before forking, the process will still be
1748 logged as if it had dbus-daemon's process ID and user ID.
1749 (fd.o #68559, Chengwei Yang)
1751 • Document more configuration elements in dbus-daemon(1)
1752 (fd.o #69125, Chengwei Yang)
1756 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
1757 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
1759 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
1760 disallowed method calls to the audit log, fixing a regression in 1.7.6
1761 (fd.o #49062, Colin Walters)
1763 • path_namespace='/' in match rules incorrectly matched nothing; it
1764 now matches everything. (fd.o #70799, Simon McVittie)
1766 D-Bus 1.7.6 (2013-10-09)
1769 The “CSI Shrewsbury” release.
1771 Build-time configuration changes:
1773 • Directory change notification via dnotify on Linux is no longer
1774 supported; it hadn't compiled successfully since 2010 in any case.
1775 If you don't have inotify (Linux) or kqueue (*BSD), you will need
1776 to send SIGHUP to the dbus-daemon when its configuration changes.
1777 (fd.o #33001, Chengwei Yang)
1779 • Compiling with --disable-userdb-cache is no longer supported;
1780 it didn't work since at least 2008, and would lead to an extremely
1781 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
1784 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
1785 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
1786 with the Autotools build system. (fd.o #66142, Chengwei Yang)
1788 • --with-valgrind=auto enables Valgrind instrumentation if and only if
1789 valgrind headers are available. The default is still --with-valgrind=no.
1790 (fd.o #56925, Simon McVittie)
1794 • Platforms with no 64-bit integer type are no longer supported.
1795 (fd.o #65429, Simon McVittie)
1797 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
1799 • Full test coverage no longer requires dbus-glib, although the tests do not
1800 exercise the shared library (only a static copy) if dbus-glib is missing.
1801 (fd.o #68852, Simon McVittie)
1805 • D-Bus Specification 0.22
1806 · Document GetAdtAuditSessionData() and
1807 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
1808 · Fix example .service file (fd.o #66481, Chengwei Yang)
1809 · Don't claim D-Bus is "low-latency" (lower than what?), just
1810 give factual statements about it supporting async use
1811 (fd.o #65141, Justin Lee)
1812 · Document the contents of .service files, and the fact that
1813 system services' filenames are constrained
1814 (fd.o #66608; Simon McVittie, Chengwei Yang)
1816 • Be thread-safe by default on all platforms, even if
1817 dbus_threads_init_default() has not been called. For compatibility with
1818 older libdbus, library users should continue to call
1819 dbus_threads_init_default(): it is harmless to do so.
1820 (fd.o #54972, Simon McVittie)
1822 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
1824 • New API: dbus_setenv(), a simple wrapper around setenv().
1825 Note that this is not thread-safe. (fd.o #39196, Simon)
1827 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
1828 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
1829 (connect to a given bus, like dbus-monitor --address=ADDRESS).
1830 dbus-send --address still exists for backwards compatibility,
1831 but is no longer documented. (fd.o #48816, Andrey Mazo)
1834 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
1839 • Avoid an infinite busy-loop if a signal interrupts waitpid()
1840 (fd.o #68945, Simon McVittie)
1842 • Clean up memory for parent nodes when objects are unexported
1843 (fd.o #60176, Thomas Fitzsimmons)
1845 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
1846 documented. Previously, it assumed its second parameter was TRUE.
1847 (fd.o #69165, Chengwei Yang)
1849 • Escape addresses containing non-ASCII characters correctly
1850 (fd.o #53499, Chengwei Yang)
1852 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
1854 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
1855 (fd.o #65923, Chengwei Yang)
1857 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
1858 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
1860 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
1861 that was never va_start()ed (fd.o #66300, Chengwei Yang)
1863 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
1865 • fix a regression test on platforms with strict alignment (fd.o #67279,
1868 • Avoid calling function parameters "interface" since certain Windows headers
1869 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
1871 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
1873 • Various thread-safety improvements to static variables (fd.o #68610,
1876 • Make "make -j check" work (fd.o #68852, Simon McVittie)
1878 • Fix a NULL pointer dereference on an unlikely error path
1879 (fd.o #69327, Sviatoslav Chagaev)
1881 • Improve valgrind memory pool tracking (fd.o #69326,
1884 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
1887 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
1888 (fd.o #66107, Chengwei Yang)
1891 · If accept4() fails with EINVAL, as it can on older Linux kernels
1892 with newer glibc, try accept() instead of going into a busy-loop.
1893 (fd.o #69026, Chengwei Yang)
1894 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
1895 for instance on Hurd or older Linux with a new glibc, try without

1902 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
1903 · Use dbus-launch from the builddir for testing, not the installed copy
1904 (fd.o #37849, Chengwei Yang)
1905 · Fix compilation if writev() is unavailable (fd.o #69409,
1907 · Remove broken support for LOCAL_CREDS credentials passing, and
1908 document where each credential-passing scheme is used (fd.o #60340,

1934 Chengwei Yang, Vasiliy Balyasnyy)
1936 D-Bus 1.7.4 (2013-06-13)
1939 The “but is your thread-safety thread-safe?” release.
1943 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
1944 of service for system services. Vulnerability reported by Alexandru Cornea.
1949 • The Windows version of libdbus now contains a C++ source file, used
1950 to provide global initialization when the library is loaded.
1951 gcc (mingw*) users should ensure that g++ is also installed.
1953 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
1954 and was never the recommended option) has been removed. Expat is now a
1959 • It should now be safe to call dbus_threads_init_default() from any thread,
1960 at any time. Authors of loadable modules and plugins that use libdbus
1961 should consider doing so during initialization.
1962 (fd.o #54972, Simon McVittie)
1964 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
1968 · dbus-run-session: experimental new tool to start a temporary D-Bus
1969 session, e.g. for regression tests or a text console, replacing
1970 certain uses of dbus-launch which weren't really correct
1971 (fd.o #39196, Simon)
1975 • In dbus-daemon, don't crash if a .service file starts with key=value
1976 (fd.o #60853, Chengwei Yang)
1979 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
1980 on a platform not defining LOG_PERROR, such as Solaris or QNX.
1981 This regressed in 1.7.0. (Simon)
1982 · Fix an assertion failure if we try to activate systemd services before
1983 systemd connects to the bus (fd.o #50199, Chengwei Yang)
1984 · Avoid compiler warnings for ignoring the return from write()
1988 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
1989 so that Windows finds them (fd.o #59733, Ralf Habacker)
1991 D-Bus 1.7.2 (2013-04-25)
1994 The “only partially opaque” release.
1996 Configuration changes:
1998 • On non-QNX Unix platforms, the default limit on fds per message in the
1999 session bus configuration has reduced from 4096 to 1024. The default
2000 limit used on the system bus was already 1024. On QNX, both limits are
2001 reduced further, to 128.
2005 • D-Bus Specification 0.21
2006 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
2007 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
2012 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
2013 (i.e. before allocating the slot) rather than returning junk

2047 or the upcoming GNOME 3.8 release.
2049 Build-time configuration changes:
2051 • The --with-dbus-session-bus-default-address configure option is no longer
2052 supported. Use the new --with-dbus-session-bus-connect-address and
2053 --with-dbus-session-bus-listen-address options instead. On Windows, you
2054 usually want them to have the same argument; on Unix, the defaults are
2057 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2058 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2059 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2061 • cmake/cross-compile.sh has been removed. Instead, please use a
2062 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2063 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2064 as documented in "info automake Cross-Compilation", and set
2065 PKG_CONFIG_PATH appropriately.
2069 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
2070 • man2html is no longer used.

2087 bus address, fixing the regression tests. (fd.o #52202, Simon)
2089 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
2090 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
2092 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

2111 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
2114 · The default session bus listening and connecting address is now
2115 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2116 and GDBus "out of the box". Use the configure options and cmake variables
2117 described above if you require a different autolaunch scope.
2118 (fd.o #38201, Simon McVittie)

2130 work to use __secure_getenv() as a followup to bug #52202
2131 broke certain configurations of gnome-keyring. Given
2132 the difficulty of making this work without extensive
2133 changes to gnome-keyring, use of __secure_getenv() is

2175 (fd.o #51032, Simon McVittie)
2177 • Disconnect "developer mode" (assertions, verbose mode etc.) from
2178 Automake maintainer mode. D-Bus developers should now configure with
2179 --enable-developer. Automake maintainer mode is now on by default;
2180 distributions can disable it with --disable-maintainer-mode.
2181 (fd.o #34671, Simon McVittie)
2183 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
2184 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)

2265 in dbus-daemon (fd.o #46273, Alban Crequy)
2268 · make dbus-daemon.exe --print-address (and --print-pid) work again
2269 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
2270 · fix duplicate case value when compiling against mingw-w64
2271 (fd.o #47321, Andoni Morales Alastruey)
2273 D-Bus 1.5.10 (2012-02-21)
2276 The "fire in Delerium" release.
2278 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2279 and SUSv2) is now required.
2281 • D-Bus Specification 0.19:
2282 · Formally define unique connection names and well-known bus names,
2283 and document best practices for interface, bus, member and error names,
2284 and object paths (fd.o #37095, Simon McVittie)
2285 · Document the search path for session and system services on Unix, and
2286 where they should be installed by build systems (fd.o #21620, fd.o #35306;
2288 · Document the systemd transport (fd.o #35232, Lennart Poettering)
2290 • Make dbus_threads_init() use the same built-in threading implementation
2291 as dbus_threads_init_default(); the user-specified primitives that it
2292 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
2294 • Allow all configured auth mechanisms, not just one (fd.o #45106,
2297 • Improve cmake build system (Ralf Habacker):
2298 · simplify XML parser dependencies (fd.o #41027)
2299 · generate build timestamp (fd.o #41029)
2300 · only create batch files on Windows
2301 · fix option and cache syntax
2302 · add help-options target
2303 · share dbus-arch-deps.h.in with autotools rather than having our
2304 own version (fd.o #41033)
2306 • Build tests successfully with older GLib, as found in e.g. Debian 6
2307 (fd.o #41219, Simon McVittie)
2309 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
2311 • Build documentation correctly if man2html doesn't support filenames on
2312 its command-line (fd.o #43875, Jack Nagel)
2314 • Improve test coverage. To get even more coverage, run the tests with
2315 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
2317 • Reduce the size of the shared library by moving functionality only used
2318 by dbus-daemon, tests etc. into their internal library and deleting
2319 unused code (fd.o #34976, #39759; Simon McVittie)
2321 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2322 setups where the default configuration must include <pidfile/> to avoid
2323 breaking traditional init, but the pid file is in fact unnecessary; use
2324 it under systemd to improve startup time a bit (fd.o #45520,
2327 • Optionally (if configured --with-valgrind) add instrumentation to debug
2328 libdbus and associated tools more meaningfully under Valgrind
2329 (fd.o #37286, Simon McVittie)
2331 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
2333 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
2335 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
2336 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
2337 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
2340 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
2344 · Replace our broken reimplementation of recursive mutexes, which has
2345 been broken since 2006, with an ordinary pthreads recursive mutex
2346 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2347 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2348 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2349 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2350 · When running under systemd, use it instead of ConsoleKit to check
2351 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2352 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2353 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2354 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2355 (fd.o #41218, Simon McVittie)
2356 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2357 helper doesn't obey environment variables to avoid privilege escalation
2358 attacks, so make the system bus follow the same rules
2359 (fd.o #21620, Simon McVittie)
2362 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2363 Jesper Dam, Ralf Habacker)
2364 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
2367 D-Bus 1.5.8 (2011-09-21)
2370 The "cross-metering" release.
2372 In addition to dead code removal and refactoring, this release contains all
2373 of the bugfixes from 1.4.16.
2375 • Clean up dead code, and make more warnings fatal in development builds
2376 (fd.o #39231, fd.o #41012; Simon McVittie)
2378 • If full test coverage is requested via --enable-tests, strictly require
2379 Python, pygobject and dbus-python, which are required by some tests; if not,
2380 and Python is missing, skip those tests rather than failing
2381 (fd.o #37847, Simon McVittie)
2383 • When using cmake, provide the same version-info API in the installed headers
2384 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2386 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
2388 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
2390 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
2393 • Fix duplicates in authors list (Ralf Habacker)
2395 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2396 (fd.o #39879, Chris Mayo)
2398 • Fix a small memory leak, and a failure to report errors, when updating
2399 a service file entry for activation (fd.o #39230, Simon McVittie)
2402 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2403 Brian Cameron, Simon McVittie)
2404 · On systems that use libcap-ng but not systemd, drop supplemental groups
2405 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2406 · Make the cmake build work again on GNU platforms (fd.o #29228,
2408 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
2409 like Solaris (fd.o #40313, Dagobert Michelsen)
2410 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2411 (fd.o #40235, Simon McVittie)
2412 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2413 (fd.o #39987, Simon McVittie)
2414 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2415 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2418 · Fix compilation on MSVC, which doesn't understand "inline" with its
2419 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2420 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2421 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2423 D-Bus 1.5.6 (2011-07-29)
2426 The "weird, gravy-like aftertaste" release.
2428 In addition to new features and refactoring, this release contains all of the
2429 bugfixes from 1.4.14.
2431 Potentially incompatible (Bustle and similar debugging tools will need
2432 changes to work as intended):
2434 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2435 different recipient) by mistake: eavesdroppers must now opt-in to this
2436 behaviour by putting "eavesdrop='true'" in the match rule, which will
2437 not have any practical effect on buses where eavesdropping is not allowed
2438 (fd.o #37890, Cosimo Alfarano)
2442 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2443 Cosimo Alfarano, Simon McVittie)
2444 · add the "eavesdrop" keyword to match rules
2445 · define eavesdropping, unicast messages and broadcast messages
2446 · stop claiming that match rules are needed to match unicast messages to you
2447 · promote the type system to be a top-level section
2449 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2450 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2451 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2453 • Consistently use atomic operations on everything that is ever manipulated
2454 via atomic ops, as was done for changes to DBusConnection's refcount in
2455 1.4.12 (fd.o #38005, Simon McVittie)
2457 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2460 • Make "make check" in a clean tree work, by not running tests until
2461 test data has been set up (fd.o #34405, Simon McVittie)
2463 • The dbus-daemon no longer busy-loops if it has a very large number of file
2464 descriptors (fd.o #23194, Simon McVittie)
2466 • Refactor message flow through dispatching to avoid locking violations if
2467 the bus daemon's message limit is hit; remove the per-connection link cache,
2468 which was meant to improve performance, but now reduces it (fd.o #34393,
2471 • Some cmake fixes (Ralf Habacker)
2473 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2474 Simon McVittie, Lennart Poettering)
2476 • Stop storing two extra byte order indicators in each D-Bus message
2477 (fd.o #38287, Simon McVittie)
2479 • Add an optional Stats interface which can be used to get statistics from
2480 a running dbus-daemon if enabled at configure time with --enable-stats
2481 (fd.o #34040, Simon McVittie)
2483 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2485 • Documentation (fd.o #36156, Simon McVittie):
2486 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2487 · install more documentation automatically, including man2html output
2488 · put dbus.devhelp in the right place (it must go in ${htmldir})
2491 · look for system services in /lib/dbus-1/system-services in addition to all
2492 the other well-known locations; note that this should always be /lib,
2493 even on platforms where shared libraries on the root FS would go in /lib64,
2494 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2495 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2497 • Windows-specific (Ralf Habacker):
2498 · fix use of a mutex for autolaunch server detection
2499 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2501 D-Bus 1.5.4 (2011-06-10)
2504 Security (local denial of service):
2506 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2507 local DoS if foreign-endian messages are relayed through the dbus-daemon
2508 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2509 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2513 • The constant to use for an infinite timeout now has a name,
2514 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2515 which can be used for source compatibility with older versions of libdbus.
2517 • If GLib and DBus-GLib are already installed, more tests will be built,
2518 providing better coverage. The new tests can also be installed via
2519 ./configure --enable-installed-tests
2520 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2524 • Consistently use atomic operations for the DBusConnection's refcount,
2525 fixing potential threading problems (fd.o #38005, Simon McVittie)
2527 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2528 small (300KiB on x86-64) and it frequently doesn't work in unusual
2529 toolchains. To optimize for minimum installed size, you should benchmark
2530 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2531 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2533 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2534 (fd.o #35880, Timothy Redaelli)
2536 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2537 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2539 • Windows-specific changes:
2540 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2542 D-Bus 1.5.2 (2011-06-01)
2545 The "Boar Hunter" release.
2547 Notes for distributors:
2549 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2550 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2551 toolchain supports it reliably, via something like:
2553 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2555 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2559 • D-Bus Specification v0.17
2560 · Reserve the extra characters used in signatures by GVariant
2561 (fd.o #34529, Simon McVittie)
2562 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2563 • Don't force -fPIE: distributions and libtool know better than we do whether
2564 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2565 • Allow --disable-gc-sections, in case your toolchain offers the
2566 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2567 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2568 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2569 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2570 • Ensure that maintainers upload documentation with the right permissions
2571 (fd.o #36130, Simon McVittie)

2576 • Log messages dropped due to quotas to syslog (fd.o #35358,
2578 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
2579 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
2580 (fd.o #35228, Lennart Poettering)
2581 • In the regression tests, don't report fds as "leaked" if they were open
2582 on startup (fd.o #35173, Simon McVittie)
2583 • Make dbus-monitor bail out if asked to monitor more than one bus,
2584 rather than silently using the last one (fd.o #26548, Will Thompson)
2585 • Clarify documentation (fd.o #35182, Simon McVittie)
2586 • Clean up minor dead code and some incorrect error handling
2587 (fd.o #33128, fd.o #29881; Simon McVittie)
2588 • Check that compiler options are supported before using them (fd.o #19681,
2591 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
2593 D-Bus 1.5.0 (2011-04-11)
2596 The "you never know when you need to tow something from your giant
2597 flying shark" release.
2599 • D-Bus Specification v0.16
2600 · Add support for path_namespace and arg0namespace in match rules
2601 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
2602 · Make argNpath support object paths, not just object-path-like strings,
2603 and document it better (fd.o #31818, Will Thompson)
2604 • Let the bus daemon implement more than one interface (fd.o #33757,
2606 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2608 • Require user intervention to compile with missing 64-bit support
2609 (fd.o #35114, Simon McVittie)
2610 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
2611 • Raise UnknownObject instead of UnknownMethod for calls to methods on
2612 paths that are not part of the object tree, and UnknownInterface for calls
2613 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
2615 D-Bus 1.4.8 (2011-04-08)
2618 The "It's like the beginning of a lobster" release.
2620 • Rename configure.in to configure.ac, and update it to modern conventions
2621 (fd.o #32245; Javier Jardón, Simon McVittie)
2622 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
2624 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
2625 --disable-x11-autolaunch configure option to prevent it altogether
2626 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
2627 • Install the documentation, and an index for Devhelp (fd.o #13495,
2628 Debian #454142; Simon McVittie, Matthias Clasen)
2629 • If checks are not disabled, check validity of string-like types and
2630 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
2631 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
2632 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
2633 • Break up a huge conditional in config-parser so gcov can produce coverage
2634 data (fd.o #10887, Simon McVittie)
2635 • List which parts of the Desktop Entry specification are applicable to
2636 .service files (fd.o #19159, Sven Herzberg)
2637 • Don't suppress service activation if two services have the same Exec=
2638 (fd.o #35750, Colin Walters)

2648 The "1, 2, miss a few, 99, 100" release.
2650 • Remove unfinished changes intended to support GTest-based tests,
2651 which were mistakenly included in 1.4.4
2653 D-Bus 1.4.4 (2010-02-17)
2656 • Switch back to using even micro versions for stable releases; 1.4.1
2657 should have been called 1.4.2, so skip that version number
2658 • Don't leave bad file descriptors being watched when spawning processes,
2659 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
2660 also LP#656134, LP#680444, LP#713157)
2661 • Check for MSG_NOSIGNAL correctly
2662 • Fix failure to detect abstract socket support (fd.o #29895)
2663 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
2664 (fd.o #32262, NB#180486)
2665 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,

2691 D-Bus 1.4.1 (20 December 2010)
2694 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
2695 crash the bus. The existing restriction to 64-levels of nesting previously
2696 only applied to the static type signature; now it also applies to dynamic
2697 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
2699 • OS X portability fixes, including launchd support.
2700 • Windows autolaunch improvements.
2701 • Various bug fixes.
