1 dbus 1.12.12 (UNRELEASED)
2 =========================
6 • Reference the freedesktop.org Code of Conduct (Simon McVittie)
10 • Remove __attribute__((__malloc__)) attribute on dbus_realloc(),
11 which does not meet the criteria for that attribute in gcc 4.7+,
12 potentially leading to miscompilation (fd.o #107741, Simon McVittie)
14 • Fix some small O(1) memory leaks (fd.o #107320, Simon McVittie)
16 • Fix printf formats for pointer-sized integers on 64-bit Windows
17 (fd.o #105662, Ralf Habacker)
21 • Add Travis-CI builds for 64-bit Windows using mingw-w64
22 (fd.o #105662, Ralf Habacker)
24 • Add Gitlab-CI integration (fd.o #108177, Simon McVittie)
26 dbus 1.12.10 (2018-08-02)
27 =========================
29 The “beam deflection” release.
33 • Prevent reading up to 3 bytes beyond the end of a truncated message.
34 This could in principle be an information leak or denial of service
35 on the system bus, but is not believed to be exploitable to crash
36 the system bus or leak interesting information in practice.
37 (fd.o #107332, Simon McVittie)
39 • Fix build with gcc 8 -Werror=cast-function-type
40 (fd.o #107349, Simon McVittie)
42 • Fix warning from gcc 8 about suspicious use of strncpy() when
43 populating struct sockaddr_un (fd.o #107350, Simon McVittie)
45 • Fix a minor memory leak when a DBusServer listens on a new address
46 (fd.o #107194, Simon McVittie)
48 • Fix an invalid NULL argument to rmdir() if a nonce-tcp DBusServer
49 runs out of memory (fd.o #107194, Simon McVittie)
51 • Don't use misleading errno-derived error names if getaddrinfo() or
52 getnameinfo() fails with a code other than EAI_SYSTEM
53 (fd.o #106395, Simon McVittie)
55 • Skip tests that require working TCP if we are in a container environment
56 where 127.0.0.1 cannot be resolved (fd.o #106812, Simon McVittie)
58 dbus 1.12.8 (2018-04-30)
59 ========================
61 The “golden super-velociraptor” release.
65 • The Devhelp documentation index is now in version 2 format
66 (fd.o #106186, Simon McVittie)
68 • Give the dbus-daemon man page some scarier warnings about
69 <allow_anonymous/> and non-local TCP, which are insecure and should
70 not be used, particularly for the standard system and session buses
71 (fd.o #106004, Simon McVittie)
75 • Fix installation of Ducktype documentation with newer yelp-build
76 versions (fd.o #106171, Simon McVittie)
78 dbus 1.12.6 (2018-03-01)
79 ========================
81 The “just the one swan, actually” release.
85 • Increase system dbus-daemon's RLIMIT_NOFILE rlimit before it drops
86 privileges, because it won't have permission afterwards. This fixes a
87 regression in dbus 1.10.18 and 1.11.0 which made the standard system bus
88 more susceptible to deliberate or accidental denial of service.
89 (fd.o #105165, David King)
91 dbus 1.12.4 (2018-02-08)
92 ========================
94 The “Stria Campania 115” release.
98 • When iterating the DBusConnection while blocking on a pending call,
99 don't wait for I/O if that pending call already has a result; and make
100 sure that whether it has a result is propagated in a thread-safe way.
101 This prevents certain multi-threaded calling patterns from blocking
102 until their timeout even when they should have succeeded sooner.
103 (fd.o #102839; Manish Narang, Michael Searle)
105 • Report the correct error if OOM is reached while trying to listen
106 on a TCP socket (fd.o #89104, Simon McVittie)
108 • Fix assertion failures in recovery from OOM while setting up a
109 DBusServer (fd.o #89104, Simon McVittie)
111 • Add a missing space to a warning message (fd.o #103729, Thomas Zajic)
113 • Expand ${bindir} correctly when pkg-config is asked for dbus_daemondir
114 (fd.o #104265, Benedikt Heine)
116 • On Linux systems with systemd < 237, if ${localstatedir}/dbus doesn't
117 exist, create it before trying to create ${localstatedir}/dbus/machine-id
118 (fd.o #104577, Chris Lesiak)
120 • Fix escaping in dbus-api-design document (fd.o #104925, Philip Withnall)
122 dbus 1.12.2 (2017-11-13)
123 ========================
125 The “spider pumpkin” release.
129 • Log a warning if a new connection cannot be accepted due to an
130 out-of-memory condition or failure to identify its AppArmor or
131 SELinux context (fd.o #103592, Simon McVittie)
135 • Make use of $(MKDIR_P) compatible with install-sh, fixing build when a
136 GNU-compatible `mkdir -p` is not available (fd.o #103521, ilovezfs)
138 • When building for Windows with Autotools, avoid `echo -e`, fixing
139 cross-compilation on non-GNU platforms like macOS
140 (fd.o #103493, Tony Theodore)
142 • Fix crashes in the server side of the nonce-tcp: transport under
143 various error conditions. This transport should normally only be used
144 on Windows, where AF_UNIX sockets are unavailable; the unix: transport
145 is the only one recommended for production use on Unix platforms.
146 (fd.o #103597, Simon McVittie)
150 • Improve test coverage on Travis-CI (Simon McVittie)
152 dbus 1.12.0 (2017-10-30)
153 ========================
155 The “gingerbread skull” release.
157 1.12.x is a new stable branch, recommended for use in OS
160 Summary of major changes between 1.10.x and 1.12.0
161 --------------------------------------------------
165 • Expat >= 2.1.0 is required.
166 • GLib >= 2.40 is required if full test coverage is enabled.
167 • [Linux] libselinux >= 2.0.86 is required if SELinux support is
169 • [Unix] dbus now requires an <inttypes.h> that defines C99 constants
170 such as PRId64 and PRIu64, except when building for Windows.
171 • [Autotools] Building from git (but not from tarballs) with Autotools
172 now requires macros from the GNU Autoconf Archive.
173 • [CMake] Builds done using CMake now require CMake 3.0.2.
175 Build-time configuration changes:
177 • Expat is now found using pkg-config. See the release notes for
179 • The --disable-compiler-optimisations and --enable-compiler-coverage
180 options no longer exist. See the release notes for 1.11.4 and 1.11.8.
181 • [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
182 options no longer exist. See the release notes for 1.11.20.
183 • [Unix] Flag files in /var/run/console/${username} are no longer
184 checked for at_console by default. See the release notes for 1.11.18.
185 • [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
186 and packagers will now need to add these downstream (most already do).
187 See the release notes for 1.11.18.
188 • [Unix] The process ID file no longer has a different default location
189 on Red Hat derivatives. See the release notes for 1.11.18.
190 • [Unix] ${runstatedir} is now independent of ${localstatedir} with
191 recent Autotools versions. See the release notes for 1.11.16.
192 • [Windows] The WINDRES variable is no longer used. See the release
197 • Eavesdropping is officially deprecated in favour of BecomeMonitor.
198 See the release notes for spec version 0.31 (in dbus 1.11.14).
199 • [Unix] Flag files in /var/run/console/${username} are deprecated.
200 See the release notes for 1.11.18.
204 • <allow> and <deny> rules in dbus-daemon configuration can now
205 include send_broadcast="true", send_broadcast="false",
206 max_unix_fds="N", min_unix_fds="N" (for some integer N).
207 See the release notes for 1.11.18.
208 • dbus_try_get_local_machine_id() is like
209 dbus_get_local_machine_id(), but returns a DBusError.
210 • New APIs around DBusMessageIter to simplify cleanup.
211 See the release notes for 1.11.16.
212 • The message bus daemon now implements the standard Introspectable,
213 Peer and Properties interfaces. See the release notes for
214 dbus 1.11.14 and spec version 0.31.
215 • DTDs for introspection XML and bus configuration are installed.
216 • dbus can be compiled to be relocatable, making it more suitable for
217 binary bundling with other software. On Windows, this is on by
219 • [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
220 never uses Linux abstract sockets, which is advantageous for
221 containers. On non-Linux it is equivalent to unix:tmpdir=….
222 See the release notes for dbus 1.11.14 and spec version 0.31.
223 • [Unix] New option "dbus-launch --exit-with-x11".
224 • [Unix] Session managers can create transient .service files in
225 $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
226 • [Unix] A sysusers.d snippet can create the messagebus user on-demand.
228 Miscellaneous behaviour changes:
230 • [Unix] The session bus now logs to syslog if it was started by
232 • [Unix] Internal warnings are logged to syslog if configured.
233 • [Unix] Exceeding an anti-DoS limit is logged to syslog if configured,
236 Changes since 1.11.22 release candidate
237 ---------------------------------------
239 Standard stable-branch changes:
241 • Disable warnings about use of deprecated functions (Simon McVittie)
245 • Don't distribute files generated by ./configure in the source tarball
246 (fd.o #103420, Simon McVittie)
250 • Remove some unused files from the git repository
251 (fd.o #103420, Simon McVittie)
253 D-Bus 1.11.22 (2017-10-23)
254 ==========================
256 The “fire surface” release.
258 This is the first release-candidate for the 1.12.0 stable release.
260 Build-time configuration changes:
262 • When building for Windows with Autotools, setting the WINDRES variable
263 no longer works to select a non-standard resource compiler. Use
264 libtool's standard RC variable instead, for example
265 "./configure RC=i686-w64-mingw32-windres"
269 • Builds done using CMake now require CMake 3.0.2.
273 • When building for Windows, improve quality of metadata in
274 libdbus-1-3.dll (fd.o #103015, Ralf Habacker)
278 • Fix a typo "uint 16" in dbus-send(1) man page
279 (fd.o #103075, David King)
281 • When building for Windows, libdbus-1-3.dll always includes version
282 information. Previously, this was missing if using CMake and any
283 non-MSVC compiler. (fd.o #103015, Ralf Habacker)
285 • Fix the build with MSVC, which regressed with the #102558 fix in
286 1.11.20. (fd.o #102558, Ralf Habacker)
290 • Simplify Windows resource embedding
291 (fd.o #103015, Simon McVittie)
293 D-Bus 1.11.20 (2017-10-03)
296 The “wraith stun” release.
298 Build-time configuration changes:
300 • The --enable-abstract-sockets and --disable-abstract-sockets options
301 no longer exist. Support for Linux's abstract AF_UNIX sockets is now
302 unconditionally enabled on Linux and disabled everywhere else.
303 (fd.o #34905, Simon McVittie)
307 • Make slower tests less likely to time out, and improve diagnostics if
308 tests do time out (fd.o #103009, Simon McVittie)
310 • On Windows, don't compile an unused stub implementation of
311 _dbus_set_signal_handler() (fd.o #103010, Simon McVittie)
315 • Be more careful to save and restore errno in POSIX async signal
316 handlers (fd.o #103010, Simon McVittie)
318 • On Windows, embed a manifest in dbus-update-activation-environment.exe
319 so that the heuristics used for UAC do not assume it needs elevated
320 privileges due to its name containing "update"
321 (fd.o #102558, Ralf Habacker)
323 • On Windows with Automake, embed version information in libdbus-1,
324 as was meant to happen in all versions since 2009
325 (fd.o #103015, Simon McVittie)
327 D-Bus 1.11.18 (2017-09-25)
330 The “vampire conquistador” release.
332 Build-time configuration changes:
334 • By default, dbus-daemon on Unix no longer checks for flag files
335 /var/run/console/${username} created by the obsolete pam_console and
336 pam_foreground PAM modules when deciding whether ${username} is
337 currently at the console. The old default behaviour can be restored
338 by specifying --with-console-auth-dir=/var/run/console in the
339 recommended Autotools build system, or
340 -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
341 now deprecated, and will be removed in dbus 1.13 unless feedback via
342 fd.o #101629 indicates that this would be problematic.
343 (fd.o #101629, Simon McVittie)
345 • LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
346 script for Cygwin, are no longer provided in the upstream dbus
347 source. We recommend that distributors who support non-systemd service
348 management should maintain their own init scripts or other service
349 manager integration as part of their downstream packaging, similar to
350 the way Debian distributes a Debian-specific LSB init script for dbus.
352 The systemd unit continues to be maintained as part of the upstream
353 dbus source, because it receives regular testing and maintenance.
355 (fd.o #101706, Simon McVittie)
357 • The process ID file created by the system bus is no longer influenced
358 by the --with-init-scripts=redhat configure option or the presence of
359 /etc/redhat-release at build time. If your OS's init script or other
360 service management relies on the Red Hat-style pid file, it can be
361 restored by specifying --with-system-pid-file=/run/messagebus.pid at
362 configure time or using the <pidfile> directive in bus configuration.
364 Note that the upstream-supplied systemd unit runs dbus-daemon with
365 the --nopidfile option, so it does not normally write a pid file,
366 regardless of whether the OS is Red-Hat-derived or not.
368 (fd.o #101706, Simon McVittie)
372 • <allow> and <deny> rules in dbus-daemon configuration can now
373 include send_broadcast="true" or send_broadcast="false", which make
374 the rule only match broadcast signals, or only match messages that
375 are not broadcast signals, respectively.
376 (fd.o #29853, Simon McVittie)
378 • <allow> and <deny> rules can now be configured to apply only to
379 messages with or without Unix file descriptors attached. This would
380 typically be used in rules like these:
381 <allow send_destination="..." max_unix_fds="0"/>
382 <deny send_destination="..." min_unix_fds="1"/>
383 <deny receive_sender="..." min_unix_fds="1"/>
384 but can also be used to set a nonzero upper limit on the number of
386 <allow send_destination="..." max_unix_fds="4"/>
387 (fd.o #101848, Simon McVittie)
389 • On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
390 now respects the HOME environment variable on the client side, and
391 on the server side when the uid attempting to connect is the same
392 as the uid of the server. This allows the automated tests to pass in
393 environments where the user's "official" home directory in /etc/passwd
394 is nonexistent, such as Debian autobuilders.
395 (fd.o #101960, Simon McVittie)
399 • When parsing dbus-daemon configuration, tell Expat not to use
400 cryptographic-quality entropy as a salt for its hash tables: we trust
401 the configuration files, so we are not concerned about algorithmic
402 complexity attacks via hash table collisions. This prevents
403 dbus-daemon --system from holding up the boot process (and causing
404 early-boot system services like systemd, logind, networkd to time
405 out) on entropy-starved embedded systems.
406 (fd.o #101858, Simon McVittie)
408 • Avoid a -Werror=declaration-after-statement build failure on Solaris
409 (fd.o #102145, Alan Coopersmith)
411 • On Unix platform, drop DBUS_SYSTEM_LOG_INFO messages from LOG_NOTICE
412 to LOG_INFO, matching how we use this log level in practice
413 (fd.o #102686, Simon McVittie)
415 D-Bus 1.11.16 (2017-07-27)
418 The “south facing garden” release.
420 Build-time configuration changes:
422 • The Autotools build system now supports varying ${runstatedir}
423 independently of ${localstatedir}, if using an Autoconf version
424 that has that feature; version 2.70 will eventually have this, but
425 many Linux distributions add it to version 2.69 as a patch.
426 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
427 and runstatedir=/run. (fd.o #101569, Simon McVittie)
431 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
432 and dbus_message_iter_abandon_container_if_open() simplify the
433 single-exit-point ("goto out") style of resource cleanup. The API
434 documentation around DBusMessageIter and containers has also been
435 clarified. (fd.o #101568, Simon McVittie)
439 • Fix the implementation of re-enabling a timeout (again) so that its
440 countdown is always restarted as intended. (fd.o #95619,
443 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
444 available to all users on the system bus (fd.o #101700, Simon McVittie)
446 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
447 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
449 • dbus_message_iter_open_container() no longer leaks memory if it runs out
450 of memory. (fd.o #101568, Simon McVittie)
452 • dbus_message_append_args_valist() no longer leaks memory if given an
453 unsupported type. This situation is still considered to be a programming
454 error which needs to be corrected by the user of libdbus.
455 (fd.o #101568, Simon McVittie)
457 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
458 will no longer report that their arguments were invalid if they run out
459 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
461 • Ensure that tests fail if they would otherwise have tried to connect to
462 the real session bus (fd.o #101698, Simon McVittie)
464 • Make build-time tests cope with finding Python 3, but not Python 2
465 (fd.o #101716, Simon McVittie)
467 Internal changes relevant to dbus developers:
469 • DBusVariant is a new mechanism to copy single values from a message into
470 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
472 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
473 Logging an ERROR message does not make the process exit; the caller
474 is responsible for calling abort() or exit(), whichever is more appropriate.
475 (fd.o #101568, Simon McVittie)
477 • Better test coverage (fd.o #101568, Simon McVittie)
479 D-Bus 1.11.14 (2017-06-29)
482 The “irrational fear of bees” release.
486 • Expat >= 2.1.0 is always required
487 • libselinux >= 2.0.86 is required if SELinux support is enabled
488 • GLib >= 2.40 is required if full test coverage is enabled
490 Build-time configuration changes:
492 • We now use pkg-config to find libexpat in Autotools builds. This requires
493 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
494 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
495 itself cause compilation failures.
497 As with all pkg-config-based configure checks, you can use
498 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
499 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
500 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
503 (fd.o #69801, Simon McVittie)
505 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
506 is required due to the removal of explicit refcounting for SIDs.
507 (fd.o #100912, Laurent Bigonville)
511 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
512 as a side-effect of a sufficiently privileged process merely reading the
513 machine ID. It is no longer copied as a side-effect of reading.
514 Running dbus-uuidgen --ensure, which should be done after installing dbus,
515 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
516 former exists and the latter does not.
517 (fd.o #101257, Simon McVittie)
519 • The undocumented Verbose interface, and the GetAllMatchRules method on
520 the undocumented Stats interface, must now be used via the object path
521 /org/freedesktop/DBus. Previously, they existed on all object paths.
522 (fd.o #101257, Simon McVittie)
524 • AddMatch() with a match rule containing eavesdrop='true' will now fail
525 unless called by either the same user as the dbus-daemon, or Unix uid 0
526 (root), matching the restrictions applied to the newer BecomeMonitor()
527 method. On the session bus this has no practical effect. On the system
528 bus this will prevent certain configurations that already did not
529 work well in practice. (fd.o #101567, Simon McVittie)
533 • D-Bus Specification version 0.31
534 · Don't require implementation-specific search paths to be lowest
536 · Correct regex syntax for optionally-escaped bytes in addresses so it
537 includes hyphen-minus, forward slash and underscore as intended
538 · Describe all message bus methods in the same section
539 · Clarify the correct object path for method calls to the message bus
540 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
541 · Document that the message bus implements Introspectable, Peer and
543 · Add new Features and Interfaces properties for message bus
545 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
547 · Don't require eavesdrop='true' to be accepted from connections not
548 sufficiently privileged to use it successfully
549 · Formally deprecate eavesdropping in favour of BecomeMonitor
550 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
551 Simon McVittie, Tom Gundersen)
553 • Implement the Properties and Peer interfaces in dbus-daemon
554 (fd.o #101257, Simon McVittie)
556 • New function dbus_try_get_local_machine_id() is like
557 dbus_get_local_machine_id(), but returning a DBusError. Other code
558 that needs the machine ID will now report a recoverable error (instead
559 of logging to stderr and aborting) if no machine ID is available.
560 Generating a machine ID is still considered to be a required part of
561 installing dbus correctly. (fd.o #13194, Simon McVittie)
563 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
564 (fd.o #101315, Laurent Bigonville)
566 • Avoid deprecated API calls when using SELinux
567 (fd.o #100912, Laurent Bigonville)
569 • Switch a test from the deprecated g_test_trap_fork() to
570 g_test_trap_subprocess(), for Windows support and better robustness
571 on Unix (fd.o #101362, Simon McVittie)
573 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
574 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
575 This prevents the two files from going out of sync on stateless or live
576 images without needing to run dbus-uuidgen, and supports older D-Bus
577 implementations that do not necessarily read /etc/machine-id themselves.
578 (fd.o #101570, Simon McVittie)
580 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
581 abstract sockets. This is preferable when used with Linux containers.
582 (fd.o #101567, Simon McVittie)
586 • Fix a reference leak when blocking on a pending call on a connection
587 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
589 • Don't put timestamps in the Doxygen-generated documentation,
590 or hard-code the build directory into builds with embedded tests,
591 for reproducible builds (fd.o #100692, Simon McVittie)
593 • Fix some integration test issues (fd.o #100686, Simon McVittie)
595 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
597 • If we somehow get an autolaunch address with multiple semicolon-separated
598 components, and they don't work, don't invalidly "pile up" errors
599 (fd.o #101257, Simon McVittie)
603 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
604 (fd.o #100715, Simon McVittie)
606 D-Bus 1.11.12 (2017-04-07)
609 The “it's something humans do” release.
613 • The session dbus-daemon now supports transient .service files
614 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
615 service directories, this directory is not monitored with inotify
616 or similar, and the service files must be named exactly
617 ${bus_name}.service. (fd.o #99825, Simon McVittie)
619 • dbus can be configured with --enable-relocation when building with
620 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
621 to make the pkg-config metadata relocatable. This is useful for
622 non-standard prefixes, and in particular for Windows installations.
623 However, it is not recommended for system-wide installations into
624 /usr, because it interferes with pkg-config's ability to filter out
625 compiler default linker directories.
627 With Autotools, the default is --enable-relocation when building
628 for Windows or --disable-relocation otherwise. With CMake, the default
629 is -DDBUS_RELOCATABLE=ON.
631 (fd.o #99721; Ralf Habacker, Simon McVittie)
633 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
634 own FindDBus.cmake macros, whether dbus was compiled with Autotools
635 or with CMake. See the end of README.cmake for more information.
636 (fd.o #99721; Ralf Habacker, Simon McVittie)
640 • Always read service file directories in the intended order
641 (fd.o #99825, Simon McVittie)
643 • When tests are skipped, don't try to kill nonexistent process 0
644 (fd.o #99825, Simon McVittie)
646 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
648 • Fix a harmless read overflow and some memory leaks in a unit test
649 (fd.o #100568, Philip Withnall)
651 • Fix some typos in test code
652 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
654 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
655 in documentation (fd.o #99901, Philip Withnall)
657 • Fix and enable compiler warnings related to -Wswitch
658 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
660 • Fix writing off the end of a fd_set when testing with valgrind
661 (fd.o #99839, Philip Withnall)
663 D-Bus 1.11.10 (2017-02-16)
666 The “purple hair gives you telekinesis?” release.
670 • AppArmor support requires at least libapparmor 2.8.95, reduced
671 from 2.10 in previous versions. One test requires 2.10 and is
672 skipped if building with an older version.
676 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
677 stable and Debian testing in addition to the older Ubuntu that is
678 the default (fd.o #98889, Simon McVittie)
680 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
682 • Silence many -Wswitch-enum and -Wswitch-default warnings
683 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
685 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
686 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
688 • Install pkg-config metadata on Unix even if building with CMake
689 (fd.o #99752, Ralf Habacker)
691 • Exclude auth mechanisms from REJECTED message if they are supported
692 in the code but but configured to be disallowed (fd.o #99621,
697 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
698 allow an attacker to overwrite a file named "nonce", in a directory
699 that the user running dbus-daemon can write, with a random value
700 known only to the user running dbus-daemon. This is unlikely to be
701 exploitable in practice, particularly since the nonce-tcp transport
702 is really only useful on Windows.
704 On Unix systems we strongly recommend using only the unix: and systemd:
705 transports, together with EXTERNAL authentication. These are the only
706 transports and authentication mechanisms enabled by default.
708 (fd.o #99828, Simon McVittie)
710 • Avoid symlink attacks in the "embedded tests", which are not enabled
711 by default and should never be enabled in production builds of dbus.
712 (fd.o #99828, Simon McVittie)
714 • Fix the implementation of re-enabling a timeout so that its
715 countdown is restarted as intended, instead of continually
716 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
718 • When receiving a message with file descriptors, do not start reading
719 the beginning of the next message, so that only one such message
720 is processed at a time. In conjunction with the fix for #95619
721 this means that processes sending many file descriptors, such as
722 systemd-logind on a system that receives very rapid ssh connections,
723 are not treated as abusive and kicked off the bus. Revert the previous
724 workaround that special-cased uid 0.
725 (fd.o #95263, LP#1591411; Simon McVittie)
727 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
728 for Windows with CMake (fd.o #99586, Ralf Habacker)
730 • Do not set Unix-specific variables when targeting Windows
731 (fd.o #99586, Ralf Habacker)
733 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
734 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
736 • Use relative install locations in CMake on Unix to respect DESTDIR,
737 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
739 • Install dbus-arch-deps.h correctly when using CMake
740 (fd.o #99586, #99721; Ralf Habacker)
742 • Improve argument validation for `dbus-test-tool spam`
743 (ffd.o #99693, Coverity #54759; Philip Withnall)
745 • Don't shift by a negative integer if a hash table becomes monstrously
746 large (fd.o #99641, Coverity #54682; Philip Withnall)
748 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
749 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
751 • Remove an unnecessary NULL check
752 (fd.o #99642, Coverity #141062; Philip Withnall)
754 • Improve error handling in unit tests and dbus-send
755 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
756 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,
757 #54710, #54711, #54714, #54715, #54718, #54721, #54724, #54726,
758 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
760 • Do not print verbose messages' timestamps to stderr if the actual message
761 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
763 D-Bus 1.11.8 (2016-11-28)
766 The “panics in the face of breakfast foods” release.
768 Build-time configuration:
770 • The new --enable-debug configure option provides an easy way to
771 enable debug symbols, disable optimization and/or enable profiling.
773 • The --enable-compile-warnings configure option can be used to control
776 • The --disable-compiler-optimisations configure option is no longer
777 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
781 • D-Bus Specification version 0.30
782 · Define the jargon term "activation" more clearly
783 · Define the jargon term "auto-starting", which is one form of activation
784 · Document the optional SystemdService key in service files
785 · Use versioned interface and bus names in most examples
786 · Clarify intended behaviour of Properties.GetAll
787 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
789 • Fix and enable a lot of compiler warnings to improve future code
790 quality. This might incidentally also fix some environment variable
792 · In particular, printf-style functions in the libdbus API are now annotated
793 with __attribute__((__format__(__printf__, *, *))) when compiling with
794 gcc or clang. This might make printf bugs in other software visible
796 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
797 Thomas Zimmermann, Simon McVittie)
799 • When running with AppArmor mediation (for example using Ubuntu's patched
800 Linux kernel), clients can no longer auto-start services unless they would
801 have been able to send the auto-starting message to the service after it
802 starts. StartServiceByName() is unaffected, and continues to be allowed by
803 default in AppArmor's <abstractions/dbus-strict> and
804 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
808 • Work around an undesired effect of the fix for CVE-2014-3637
809 (fd.o #80559), in which processes that frequently send fds, such as
810 logind during a flood of new PAM sessions, can get disconnected for
811 continuously having at least one fd "in flight" for too long;
812 dbus-daemon interprets that as a potential denial of service attack.
813 The workaround is to disable that check for uid 0 process such as
814 logind, with a message in the system log. The bug remains open while
815 we look for a more general solution.
816 (fd.o #95263, LP#1591411; Simon McVittie)
818 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
819 was disabled at compile time. That test is not expected to work
820 in that configuration. (fd.o #98665, Simon McVittie)
822 D-Bus 1.11.6 (2016-10-10)
825 The “darkly whimsical” release.
829 • Do not treat ActivationFailure message received from root-owned systemd
830 name as a format string. In principle this is a security vulnerability,
831 but we do not believe it is exploitable in practice, because only
832 privileged processes can own the org.freedesktop.systemd1 bus name, and
833 systemd does not appear to send activation failures that contain "%".
835 Please note that this probably *was* exploitable in dbus versions
836 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
837 the time was only thought to be a denial of service vulnerability
838 (CVE-2015-0245). If you are still running one of those versions,
839 patch or upgrade immediately.
841 (fd.o #98157, Simon McVittie)
845 • D-Bus Specification version 0.29
846 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
847 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
849 • Log to syslog when we exceed various anti-DoS limits, and add test
850 coverage for them (fd.o #86442, Simon McVittie)
852 • Improve syslog handling so that _dbus_warn() and similar warnings
853 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
854 and log to syslog (instead of /dev/null) when dbus-daemon is started by
855 dbus-launch. (fd.o #97009, Simon McVittie)
857 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
858 (fd.o #89011, Philip Withnall)
860 • When logging messages about service activation, mention which peer
861 requested the activation (fd.o #68212, Philip Withnall)
863 • On Linux, mention the LSM label (if available) whenever we print
864 debug information about a peer (fd.o #68212, Philip Withnall)
868 • Harden dbus-daemon against malicious or incorrect ActivationFailure
869 messages by rejecting them if they do not come from a privileged
870 process, or if systemd activation is not enabled
871 (fd.o #98157, Simon McVittie)
873 • Avoid undefined behaviour when setting reply serial number without going
874 via union DBusBasicValue (fd.o #98035, Marc Mutz)
876 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
877 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
879 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
881 D-Bus 1.11.4 (2016-08-15)
884 The “copper pickaxe” release.
888 • Building from git (but not from tarballs) now requires
889 macros from the GNU Autoconf Archive, for example the autoconf-archive
890 package in Debian or Fedora derivatives.
892 Build-time configuration:
894 • The option to enable coverage instrumentation has changed from
895 --enable-compiler-coverage to --enable-code-coverage.
899 • D-Bus Specification version 0.28
900 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
902 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
903 minimizing failed connections under heavy load
904 (fd.o #95264, Lennart Poettering)
906 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
908 • Use the same regression tests for subprocess starting on Unix and Windows
909 (fd.o #95191, Ralf Habacker)
911 • Print timestamps and thread IDs in verbose messages
912 (fd.o #95191, Ralf Habacker)
914 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
915 pointing to /dev/null (fd.o #97008, Simon McVittie)
917 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
918 (fd.o #88922, Thomas Zimmermann)
922 • On Windows, fix a memory leak in replacing the installation prefix
923 (fd.o #95191, Ralf Habacker)
925 • On Linux, when dbus-daemon is run with reduced susceptibility to the
926 OOM killer (typically via systemd), do not let child processes inherit
927 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
929 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
930 even if a parent process incorrectly starts them with stdin, stdout
931 and/or stderr closed (fd.o #97008, Simon McVittie)
933 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
934 contains a semicolon (fd.o #94746, Thiago Macieira)
936 • Fix memory leaks and thread safety in subprocess starting on Windows
937 (fd.o #95191, Ralf Habacker)
939 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
940 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
942 • In tests that exercise correct handling of crashing D-Bus services,
943 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
945 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
947 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
948 in some test cases (fd.o #93909, Nick Lewycky)
950 • Add assertions to reassure a static analysis tool
951 (fd.o #93210, Deepika Aggarwal)
953 • Be explicit about enum comparison when loading XML
954 (fd.o #93205, Deepika Aggarwal)
956 • update-activation-environment: produce better diagnostics on error
957 (fd.o #96653, Simon McVittie)
959 • Avoid various compiler warnings with gcc 6
960 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
962 • On Unix when configured to use the system log, report as "dbus-daemon",
963 not as "dbus" (fd.o #97009, Simon McVittie)
965 • During unit tests, reduce the amount we write to the system log
966 (fd.o #97009, Simon McVittie)
968 D-Bus 1.11.2 (2016-03-07)
971 The “pneumatic drill vs. Iron Maiden” release.
975 • Enable "large file support" on systems where it exists: dbus-daemon
976 is not expected to open large files, but it might need to stat files
977 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
979 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
980 which might result in a pedantic C compiler not copying the entire contents
981 of a DBusMessageIter; statically assert that this is not an ABI change
982 in practice (fd.o #94136, Simon McVittie)
984 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
985 (fd.o #94244, Dmitri Iouchtchenko)
987 • Correctly report test failures in C tests from run-test.sh
988 (fd.o #93379; amit tewari, Simon McVittie)
990 • When tests are enabled, run all the marshal-validate tests, not just
991 the even-numbered ones (fd.o #93908, Nick Lewycky)
993 • Correct the expected error from one marshal-validate test, which was
994 previously not run due to the above bug (fd.o #93908, Simon McVittie)
996 • Fix compilation under CMake when embedded tests are disabled
997 (fd.o #94094, eric.hyer)
1001 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
1002 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
1004 • When building with CMake, use the same gcc/clang warnings as under Autotools,
1005 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
1007 • test/name-test: make C tests produce TAP output and run them directly, not
1008 via run-test.sh (fd.o #92899, Simon McVittie)
1010 • Under CMake when cross-compiling for Windows on Unix, run the tests
1011 under Wine even if binfmt_misc support is not available
1012 (fd.o #88966, Ralf Habacker)
1014 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
1015 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
1017 • Factor out some functions that will be needed in future for a Windows
1018 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
1020 D-Bus 1.11.0 (2015-12-02)
1023 The “peppermint deer” release.
1027 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
1028 C99 constants such as PRId64 and PRIu64.
1032 • D-Bus Specification version 0.27
1033 · Specify that services should not reply if NO_REPLY_EXPECTED was used
1034 (fd.o #75749, Lars Uebernickel)
1036 • Add a script to do continuous-integration builds, and metadata to run it
1037 on travis-ci.org. To use this, clone the dbus git repository on GitHub
1038 and set it up with travis-ci.org; the only special setting needed is
1039 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
1041 • If dbus-daemon is run with --systemd-activation, do not require
1042 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
1046 • Re-order dbus-daemon startup so that on SELinux systems, the thread
1047 that reads AVC notifications retains the ability to write to the
1048 audit log (fd.o #92832, Laurent Bigonville)
1050 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
1052 • When using the Monitoring interface, match messages' destinations
1053 (fd.o #92074, Simon McVittie)
1055 • On Linux with systemd, stop installing a reference to the obsolete
1056 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
1059 • On Windows, when including configuration files with <include> or
1060 <includedir>, apply the same relocation as for the Exec paths
1061 in .service files (fd.o #92028, Simon McVittie)
1063 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
1065 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
1067 D-Bus 1.10.6 (2015-12-01)
1070 The “marzipan beetles” release.
1074 • On Unix when running tests as root, don't assert that root and
1075 the dbus-daemon user can still call UpdateActivationEnvironment;
1076 assert that those privileged users can call BecomeMonitor instead
1077 (fd.o #93036, Simon McVittie)
1079 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
1082 • On Windows Autotools builds, don't run tests that rely on
1083 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
1085 D-Bus 1.10.4 (2015-11-17)
1088 The “Frostburn Canyon” release.
1092 • GetConnectionCredentials, GetConnectionUnixUser and
1093 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
1094 will now return details of the dbus-daemon itself. This is required
1095 to be able to call SetEnvironment on systemd.
1096 (fd.o #92857, Jan Alexander Steffens)
1100 • Make UpdateActivationEnvironment always fail with AccessDenied on the
1101 system bus. Previously, it was possible to configure it so root could
1102 call it, but the environment variables were not actually used,
1103 because the launch helper would discard them.
1104 (fd.o #92857, Jan Alexander Steffens)
1106 • On Unix with --systemd-activation on a user bus, make
1107 UpdateActivationEnvironment pass on its arguments to systemd's
1108 SetEnvironment method, solving inconsistency between the environments
1109 used for traditional activation and systemd user-service activation.
1110 (fd.o #92857, Jan Alexander Steffens)
1112 • On Windows, don't crash if <syslog/> or --syslog is used
1113 (fd.o #92538, Ralf Habacker)
1115 • On Windows, fix a memory leak when setting a DBusError from a Windows
1116 error (fd.o #92721, Ralf Habacker)
1118 • On Windows, don't go into infinite recursion if we abort the process
1119 with backtraces enabled (fd.o #92721, Ralf Habacker)
1121 • Fix various failing tests, variously on Windows and cross-platform:
1122 · don't test system.conf features (users, groups) that only make sense
1123 on the system bus, which is not supported on Windows
1124 · don't call _dbus_warn() when we skip a test, since it is fatal
1125 · fix computation of expected <standard_session_servicedirs/>
1126 · when running TAP tests, translate newlines to Unix format, fixing
1127 cross-compiled tests under Wine on Linux
1128 · don't stress-test refcounting under Wine, where it's really slow
1129 · stop assuming that a message looped-back to the test will be received
1131 · skip some system bus tests on Windows since they make no sense there
1132 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
1134 D-Bus 1.10.2 (2015-10-26)
1137 The “worst pies in London” release.
1141 • Correct error handling for activation: if there are multiple attempts
1142 to activate the same service and it fails immediately, the first attempt
1143 would get the correct reply, but the rest would time out. We now send
1144 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
1146 • If BecomeMonitor is called with a syntactically invalid match rule,
1147 don't crash with an assertion failure, fixing a regression in 1.9.10.
1148 This was not exploitable as a denial of service, because the check
1149 for a privileged user is done first. (fd.o #92298, Simon McVittie)
1151 • On Linux with --enable-user-session, add the bus address to the
1152 environment of systemd services for better backwards compatibility
1153 (fd.o #92612, Jan Alexander Steffens)
1155 • On Windows, fix the logic for replacing the installation prefix
1156 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
1158 • On Windows, if installed in the conventional layout with ${prefix}/etc
1159 and ${prefix}/share, use relative paths between bus configuration files
1160 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
1162 • Make more of the regression tests pass in Windows builds (fd.o #92538,
1165 D-Bus 1.10.0 (2015-08-25)
1170 This is a new stable branch, recommended for use in OS distributions.
1174 • distribute test/tap-test.sh.in, even if the tarball was built without
1175 tests enabled (fd.o #91684, Simon McVittie)
1176 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
1178 Summary of major changes since 1.8.0:
1180 • The basic setup for the well-known system and session buses is
1181 now done in read-only files in ${datadir} (normally /usr/share).
1182 See the NEWS entry for 1.9.18 for details.
1184 • AppArmor integration has been merged, with features similar to the
1185 pre-existing SELinux integration. It is mostly compatible with the
1186 patches previously shipped by Ubuntu, with one significant change:
1187 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
1188 by GetConnectionCredentials and was not included.
1190 • The --enable-user-session configure option can be enabled
1191 by OS integrators intending to use systemd to provide a session bus
1192 per user (in effect, treating all concurrent graphical and non-graphical
1193 login sessions as one large session).
1195 • The new listenable address mode "unix:runtime=yes" listens on
1196 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
1197 user session. libdbus and "dbus-launch --autolaunch" will connect to
1198 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
1201 • All executables are now dynamically linked to libdbus-1.
1202 Previously, some executables, most notably dbus-daemon, were statically
1203 linked to a specially-compiled variant of libdbus. This results in
1204 various private functions in the _dbus namespace being exposed by the
1205 shared library. These are not API, and must not be used outside
1206 the dbus source tree.
1208 • On platforms with ELF symbol versioning, all public symbols
1209 are versioned LIBDBUS_1_3.
1213 • org.freedesktop.DBus.GetConnectionCredentials returns
1214 LinuxSecurityLabel where supported
1215 • org.freedesktop.DBus.Monitoring interface (privileged)
1216 · BecomeMonitor method supersedes match rules with eavesdrop=true,
1217 which are now deprecated
1218 • org.freedesktop.DBus.Stats interface (semi-privileged)
1219 · now enabled by default
1220 · new GetAllMatchRules method
1221 • org.freedesktop.DBus.Verbose interface (not normally compiled)
1222 · toggles the effect of DBUS_VERBOSE
1227 • dbus-update-activation-environment
1229 New optional dependencies:
1231 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
1232 • Complete documentation requires Ducktype and yelp-tools
1233 • Full test coverage requires GLib 2.36 and PyGI
1234 • AppArmor integration requires libapparmor and optionally libaudit
1236 Dependencies removed:
1240 D-Bus 1.9.20 (2015-08-06)
1243 The “Remember Tomorrow” release.
1245 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
1250 • Don't second-guess what the ABI of poll() is, allowing it to be used
1251 on Integrity RTOS and other unusual platforms (fd.o #90314;
1252 Rolland Dudemaine, Simon McVittie)
1254 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
1255 both enabled (fd.o #89225, Simon McVittie)
1257 • Log audit events for AppArmor/SELinux policy violations whenever
1258 we have CAP_AUDIT_WRITE, even if not the system bus
1259 (fd.o #83856, Laurent Bigonville)
1261 D-Bus 1.9.18 (2015-07-21)
1264 The “Pirate Elite” release.
1266 Configuration changes:
1268 • The basic setup for the well-known system and session buses is now done
1269 in read-only files in ${datadir}, moving a step closer to systems
1270 that can operate with an empty /etc directory. In increasing order
1273 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
1274 the default message policies.
1275 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
1276 dbus still installs a trivial version of each, for documentation
1277 purposes; putting configuration directives in these files is deprecated.
1278 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
1279 to install "drop-in" configuration snippets (any packages
1280 using those directories should explicitly depend on at least this
1282 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
1283 or third-party software to install "drop-in" configuration snippets
1284 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
1287 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
1288 and "s*" refers to either system or session as appropriate.
1290 (fd.o #89280, Dimitri John Ledkov)
1294 • Fix a memory leak when GetConnectionCredentials() succeeds
1295 (fd.o #91008, Jacek Bukarewicz)
1297 • Ensure that dbus-monitor does not reply to messages intended for others,
1298 resulting in its own disconnection (fd.o #90952, Simon McVittie)
1300 D-Bus 1.9.16 (2015-05-14)
1303 The “titanium barns” release.
1307 • Automake 1.13 is now required when compiling from git or modifying
1312 • On Unix platforms, change the default configuration for the session bus
1313 to only allow EXTERNAL authentication (secure kernel-mediated
1314 credentials-passing), as was already done for the system bus.
1316 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
1317 unpredictable pseudo-random numbers.
1319 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
1320 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
1321 NFS or similar, you will need to reconfigure the session bus to accept
1322 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
1325 (fd.o #90414, Simon McVittie)
1327 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
1328 transport, UUIDs or any other reason, fail if we cannot obtain entropy
1329 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
1330 occurs, instead of silently falling back to low-entropy pseudorandom
1331 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
1335 • Add dbus_message_iter_get_element_count()
1336 (fd.o #30350; Christian Dywan, Simon McVittie)
1338 • Introduce new internal DBusSocket and DBusPollable types so we can
1339 stop treating the Windows SOCKET type as if it was int. DBusSocket
1340 is specifically a socket, cross-platform. DBusPollable is whatever
1341 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
1342 (fd.o #89444; Ralf Habacker, Simon McVittie)
1344 • All regression tests now output TAP <https://testanything.org/>
1345 (fd.o #89846, Simon McVittie)
1347 • Internal APIs consistently use signed values for timestamps
1348 (fd.o #18494, Peter McCurdy)
1350 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
1351 (fd.o #88812, Simon McVittie)
1353 • Clean up a lot of compiler warnings
1354 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
1358 • Add locking to DBusCounter's reference count and notify function
1359 (fd.o #89297, Adrian Szyndela)
1361 • Ensure that DBusTransport's reference count is protected by the
1362 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
1364 • Correctly release DBusServer mutex before early-return if we run out
1365 of memory while copying authentication mechanisms (fd.o #90021,
1368 • Make dbus-test-tool and dbus-update-activation-environment portable
1369 to Windows (fd.o #90089, Ralf Habacker)
1371 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
1372 Ralf Habacker, Simon McVittie)
1374 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
1377 • Clean up some memory and fd leaks in test code and tools
1378 (fd.o #90021, Ralf Habacker)
1380 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
1381 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
1383 • CMake generates a versioned shared library even if the revision is 0,
1384 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
1386 D-Bus 1.9.14 (2015-03-02)
1389 The “don't stand in the poison cloud” release.
1393 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
1394 were previously linked to a static version of libdbus.
1396 • The tests no longer require dbus-glib in order to exercise the libdbus
1397 shared library; they are always linked to libdbus now.
1399 Build-time configuration:
1401 • The new --enable-user-session option, off by default, can be enabled
1402 by OS integrators intending to use systemd to provide a session bus
1403 per user (in effect, treating all concurrent graphical and non-graphical
1404 login sessions as one large session)
1408 • All executables are now linked dynamically to libdbus.
1409 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
1411 • On platforms that support them (GNU libc and possibly others),
1412 libdbus now has versioned symbols for its public API.
1413 All public symbols (visible in the header files) are currently
1414 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
1415 dbus_internal have a version that changes with each release, and
1416 must not be used by applications. (also fd.o #83115)
1418 • New listenable address mode "unix:runtime=yes" which listens on
1419 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1420 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1422 • Add optional systemd units for a per-user bus listening on
1423 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1425 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1426 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1429 • New dbus-update-activation-environment tool uploads environment
1430 variables to "dbus-daemon --session" and optionally "systemd --user",
1431 primarily as a way to keep the per-user bus compatible with
1432 distributions' existing X11 login scripts (also fd.o #61301)
1434 • <includedir/> elements in dbus-daemon configuration are now silently
1435 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1437 • Add microsecond-resolution timestamps to the default output of
1438 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1442 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1443 (fd.o #89222, Simon McVittie)
1445 D-Bus 1.9.12 (2015-02-19)
1448 The “monster lasagna” release.
1452 • Ducktype and yelp-tools are now required to build complete documentation
1453 (they are optional for normal builds).
1457 • D-Bus Specification version 0.26
1458 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1459 · document the BecomeMonitor method
1461 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1462 (fd.o #89041; Tyler Hicks, Simon McVittie)
1464 • On Linux, add support for AppArmor mediation of message sending and
1465 receiving and name ownership (paralleling existing SELinux mediation
1466 support), and eavesdropping (a new check, currently AppArmor-specific)
1467 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1469 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1470 that have printable ASCII contents; we previously only did this for
1471 unterminated bytestrings (fd.o #89109, Simon McVittie)
1473 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1475 • On Windows, add WindowsSID to GetConnectionCredentials
1476 (fd.o #54445, Ralf Habacker)
1478 • Improve clarity of dbus-monitor --profile output and add more columns
1479 (fd.o #89165, Ralf Habacker)
1481 • Add a man page for dbus-test-tool, and build it under CMake as well
1482 as Autotools (fd.o#89086, Simon McVittie)
1484 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1485 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1486 (fd.o #88896, Ralf Habacker)
1490 • Reduce the number of file descriptors used in the fd-passing test,
1491 avoiding failure under the default Linux fd limit, and automatically
1492 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1494 D-Bus 1.9.10 (2015-02-09)
1497 The “sad cyborgs” release.
1499 Security fixes merged from 1.8.16:
1501 • Do not allow non-uid-0 processes to send forged ActivationFailure
1502 messages. On Linux systems with systemd activation, this would
1503 allow a local denial of service: unprivileged processes could
1504 flood the bus with these forged messages, winning the race with
1505 the actual service activation and causing an error reply
1506 to be sent back when service auto-activation was requested.
1507 This does not prevent the real service from being started,
1508 so the attack only works while the real service is not running.
1509 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1513 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1514 similar tools receive messages without altering the security properties
1515 of the system bus, by calling the new BecomeMonitor method on a
1516 private connection. This bypasses the normal <allow> and <deny> rules
1517 entirely, so to preserve normal message-privacy assumptions, only root
1518 is allowed to do this on the system bus. Restricted environments,
1519 such as Linux with LSMs, should lock down access to the Monitoring
1520 interface. (fd.o #46787, Simon McVittie)
1522 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1523 dbus-daemon supports it and access permissions allow it.
1524 It still supports the previous approach ("eavesdropping" match rules)
1525 for compatibility with older bus daemons. (fd.o #46787, Simon)
1527 • dbus-monitor can now log the message stream as binary data for later
1528 analysis, with either no extra framing beyond the normal D-Bus headers,
1529 or libpcap-compatible framing treating each D-Bus message
1530 as a captured packet. (fd.o #46787, Simon)
1534 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1536 • On Unix, forcibly terminate regression tests after 60 seconds to
1537 prevent them from blocking continuous integration frameworks
1538 (fd.o #46787, Simon)
1540 D-Bus 1.9.8 (2015-02-03)
1543 The “all the types of precipitation” release.
1547 • full test coverage now requires GLib 2.36
1548 • full test coverage now requires PyGI (PyGObject 3,
1549 "import gi.repository.GObject") instead of the
1550 obsolete PyGObject 2 ("import gobject")
1554 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1556 • better regression test coverage, including systemd activation
1557 (fd.o #57952, #88810; Simon McVittie)
1561 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1562 turned off (fd.o #88808, Simon McVittie)
1564 • TCP sockets on Windows no longer fail to listen approximately 1 time
1565 in 256, caused by a logic error that should have always made it fail but
1566 was mitigated by incorrect endianness for the port number
1567 (fd.o #87999, Ralf Habacker)
1569 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1571 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1572 previous 64, completing a previous fix which only worked under
1573 Autotools (fd.o #71297, Ralf Habacker)
1575 • on Windows, if the IP family is unspecified only use IPv4,
1576 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1578 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1580 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1582 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1585 D-Bus 1.9.6 (2015-01-05)
1588 The “I do have a bread knife” release.
1592 • Do not allow calls to UpdateActivationEnvironment from uids other than
1593 the uid of the dbus-daemon. If a system service installs unsafe
1594 security policy rules that allow arbitrary method calls
1595 (such as CVE-2014-8148) then this prevents memory consumption and
1596 possible privilege escalation via UpdateActivationEnvironment.
1598 We believe that in practice, privilege escalation here is avoided
1599 by dbus-daemon-launch-helper sanitizing its environment; but
1600 it seems better to be safe.
1602 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1603 on object paths other than /org/freedesktop/DBus. Some system services
1604 install unsafe security policy rules that allow arbitrary method calls
1605 to any destination, method and interface with a specified object path;
1606 while less bad than allowing arbitrary method calls, these security
1607 policies are still harmful, since dbus-daemon normally offers the
1608 same API on all object paths and other system services might behave
1613 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1614 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1616 D-Bus 1.9.4 (2014-11-24)
1619 The “extra-sturdy caramel” release.
1623 • Partially revert the CVE-2014-3639 patch by increasing the default
1624 authentication timeout on the system bus from 5 seconds back to 30
1625 seconds, since this has been reported to cause boot regressions for
1626 some users, mostly with parallel boot (systemd) on slower hardware.
1628 On fast systems where local users are considered particularly hostile,
1629 administrators can return to the 5 second timeout (or any other value
1630 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1633 <limit name="auth_timeout">5000</limit>
1636 (fd.o #86431, Simon McVittie)
1638 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1639 (fd.o #86431, Simon McVittie)
1641 • Send back an AccessDenied error if the addressed recipient is not allowed
1642 to receive a message (and in builds with assertions enabled, don't
1643 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1645 D-Bus 1.9.2 (2014-11-10)
1648 The “structurally unsound flapjack” release.
1652 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1653 so that CVE-2014-3636 part A cannot exhaust the system bus'
1654 file descriptors, completing the incomplete fix in 1.8.8.
1655 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1659 • D-Bus Specification version 0.25
1660 · new value 'const' for EmitsChangedSignal annotation
1661 (fd.o #72958, Lennart Poettering)
1662 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1663 (fd.o #83449; Lennart Poettering, Simon McVittie)
1664 · annotate table of types with reserved/basic/container, and for
1665 basic types, fixed/string-like
1666 · clarify arbitrary limits by quoting them in mebibytes
1668 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1669 (fd.o #83449, Simon McVittie)
1671 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1672 useful for debugging and performance testing:
1673 · dbus-test-tool spam: send repeated messages
1674 · dbus-test-tool echo: send an empty reply for all method calls
1675 · dbus-test-tool black-hole: do not reply to method calls
1676 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1678 • Add support for process ID in credentials-passing on NetBSD
1679 (fd.o #69702, Patrick Welche)
1681 • Add an example script to find potentially undesired match rules
1682 (fd.o #84598, Alban Crequy)
1684 • Document the central assumption that makes our use of credentials-passing
1685 secure (fd.o #83499, Simon McVittie)
1687 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1688 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1693 • Use a less confusing NoReply message when disconnected with a reply pending
1694 (fd.o #76112, Simon McVittie)
1696 • Make the .pc file relocatable by letting pkg-config do all variable
1697 expansion itself (fd.o #75858, Руслан Ижбулатов)
1699 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1700 (fd.o #85563, Patrick Welche)
1702 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1704 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1705 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1707 • Do not fail the tests if a parent process has leaked non-close-on-exec
1708 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1710 • Do not fail the tests on Unix platforms with incomplete
1711 credentials-passing support, but do fail if we can't pass credentials
1712 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1713 (fd.o #69702, Simon McVittie)
1715 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1716 when building with cmake, and expand test coverage there
1717 (fd.o #73689; Ralf Habacker, Simon McVittie)
1719 D-Bus 1.9.0 (2014-10-01)
1722 The “tiered cheeses” release.
1726 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1727 requires either the libsystemd or libsd-daemon shared library, dropping the
1728 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1730 Build-time configuration changes:
1732 • The Stats interface is now enabled by default, and locked-down to

1739 • The CMake build system now builds the same shared library name as Autotools
1740 on at least Linux and Windows:
1741 - on Linux (and perhaps other Unix platforms), it previously built
1742 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1743 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1744 - on Windows, it previously built either libdbus-1.dll (release) or
1745 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1746 libdbus-1.dll for compatibility with older applications.

1814 could lead to a 4-byte heap buffer overrun.
1815 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1817 • Reduce default for maximum Unix file descriptors passed per message
1818 from 1024 to 16, preventing a uid with the default maximum number of
1819 connections from exhausting the system bus' file descriptors under
1820 Linux's default rlimit. Distributors or system administrators with a
1821 more restrictive fd limit may wish to reduce these limits further.

1926 D-Bus 1.8.0 (2014-01-20)
1929 The “Wolverine distrusts my printer” release.
1931 This starts a new stable branch. The 1.6.x branch is now considered to be
1932 outdated, and will only receive fixes for serious bugs such as security
1933 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1934 are unlikely to get any more releases, but if distributors still need to
1935 support them, please share security patches via upstream.
1937 Summary of changes since 1.6.x:
1939 • libdbus always behaves as if dbus_threads_init_default() had been called
1940 (thread-safety by default)
1941 • new dbus-run-session tool, replacing certain misuses of dbus-launch
1942 • dbus-monitor can talk to outdated versions of dbus-daemon again
1943 • new org.freedesktop.DBus.GetConnectionCredentials method
1944 • GetConnectionUnixProcessID also works correctly on Windows, returning
1945 the Windows process ID
1946 • GetConnectionWindowsSID returns the correct SID on Windows
1947 • expat is required, libxml2 can no longer be used as a substitute
1948 • the userDB cache is required, and cannot be disabled
1949 • a 64-bit integer type (either int, long, long long or _int64) is required
1950 • better systemd-journald integration on Linux
1951 • fixed long-standing fd and array leaks when failing to parse a message
1952 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
1953 when using certain object-path allocation patterns, notably in Avahi
1954 • better defaults for Windows support
1955 • better CMake support
1956 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
1957 • the source language for the man pages is now Docbook XML
1959 Enhancements since 1.7.10:
1961 • Enhance the CMake build system to check for GLib and compile/run
1962 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
1966 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
1969 • fix compilation of systemd journal support on older systemd versions where
1970 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
1972 • fix compilation on older MSVC versions by including stdlib.h
1973 (fd.o #73455, Ralf Habacker)
1975 • Allow <allow_anonymous/> to appear in an included configuration file
1976 (fd.o #73475, Matt Hoosier)
1978 Test behaviour changes since 1.7.10:
1980 • If the tests crash with an assertion failure, they no longer default to
1981 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
1982 environment if you want the old behaviour.
1984 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
1985 can be run with an external dbus-daemon by setting
1986 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
1987 an unusually-configured dbus-daemon are skipped.
1989 D-Bus 1.7.10 (2014-01-06)
1992 The “weighted companion cube” release.
1994 This is a release candidate for D-Bus 1.8.
1996 D-Bus Specification 0.23:
1998 • don't require messages with no INTERFACE to be dispatched
1999 (fd.o #68597, Simon McVittie)
2001 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
2004 • define "listenable" and "connectable" addresses, and discuss
2005 the difference (fd.o #61303, Simon McVittie)
2009 • support printing Unix file descriptors in dbus-send, dbus-monitor
2010 (fd.o #70592, Robert Ancell)
2012 • don't install systemd units if --disable-systemd is given
2013 (fd.o #71818, Chengwei Yang)
2017 • don't leak memory on out-of-memory while listing activatable or
2018 active services (fd.o #71526, Radoslaw Pajak)
2020 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
2022 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
2024 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
2025 and DBUS__SEND_MSG are numerically equal to their values in the
2026 reference policy (fd.o #88719, osmond sun)
2028 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
2029 (fd.o #71366, Matt Fischer)
2031 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
2032 winsock2.h (fd.o #71405, Matt Fischer)
2034 • do not return failure from _dbus_read_nonce() with no error set,
2035 preventing a potential crash (fd.o #72298, Chengwei Yang)
2037 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
2038 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
2040 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
2041 which doesn't do anything anyway on at least Linux and FreeBSD
2042 (fd.o #69492, Simon McVittie)
2044 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
2045 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
2046 for credentials more correctly (fd.o #69492, Simon McVittie)
2048 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
2049 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
2052 • refresh cached policy rules for existing connections when bus
2053 configuration changes (fd.o #39463, Chengwei Yang)
2055 D-Bus 1.7.8 (2013-11-01)
2058 The “extreme hills” release.
2062 • If systemd support is enabled, libsystemd-journal is now required.
2066 • When activating a non-systemd service under systemd, annotate its
2067 stdout/stderr with its bus name in the Journal. Known limitation:
2068 because the socket is opened before forking, the process will still be
2069 logged as if it had dbus-daemon's process ID and user ID.
2070 (fd.o #68559, Chengwei Yang)
2072 • Document more configuration elements in dbus-daemon(1)
2073 (fd.o #69125, Chengwei Yang)
2077 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
2078 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
2080 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
2081 disallowed method calls to the audit log, fixing a regression in 1.7.6
2082 (fd.o #49062, Colin Walters)
2084 • path_namespace='/' in match rules incorrectly matched nothing; it
2085 now matches everything. (fd.o #70799, Simon McVittie)
2087 D-Bus 1.7.6 (2013-10-09)
2090 The “CSI Shrewsbury” release.
2092 Build-time configuration changes:
2094 • Directory change notification via dnotify on Linux is no longer
2095 supported; it hadn't compiled successfully since 2010 in any case.
2096 If you don't have inotify (Linux) or kqueue (*BSD), you will need
2097 to send SIGHUP to the dbus-daemon when its configuration changes.
2098 (fd.o #33001, Chengwei Yang)
2100 • Compiling with --disable-userdb-cache is no longer supported;
2101 it didn't work since at least 2008, and would lead to an extremely
2102 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
2105 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
2106 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
2107 with the Autotools build system. (fd.o #66142, Chengwei Yang)
2109 • --with-valgrind=auto enables Valgrind instrumentation if and only if
2110 valgrind headers are available. The default is still --with-valgrind=no.
2111 (fd.o #56925, Simon McVittie)
2115 • Platforms with no 64-bit integer type are no longer supported.
2116 (fd.o #65429, Simon McVittie)
2118 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
2120 • Full test coverage no longer requires dbus-glib, although the tests do not
2121 exercise the shared library (only a static copy) if dbus-glib is missing.
2122 (fd.o #68852, Simon McVittie)
2126 • D-Bus Specification 0.22
2127 · Document GetAdtAuditSessionData() and
2128 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
2129 · Fix example .service file (fd.o #66481, Chengwei Yang)
2130 · Don't claim D-Bus is "low-latency" (lower than what?), just
2131 give factual statements about it supporting async use
2132 (fd.o #65141, Justin Lee)
2133 · Document the contents of .service files, and the fact that
2134 system services' filenames are constrained
2135 (fd.o #66608; Simon McVittie, Chengwei Yang)
2137 • Be thread-safe by default on all platforms, even if
2138 dbus_threads_init_default() has not been called. For compatibility with
2139 older libdbus, library users should continue to call
2140 dbus_threads_init_default(): it is harmless to do so.
2141 (fd.o #54972, Simon McVittie)
2143 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
2145 • New API: dbus_setenv(), a simple wrapper around setenv().
2146 Note that this is not thread-safe. (fd.o #39196, Simon)
2148 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
2149 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
2150 (connect to a given bus, like dbus-monitor --address=ADDRESS).
2151 dbus-send --address still exists for backwards compatibility,
2152 but is no longer documented. (fd.o #48816, Andrey Mazo)
2155 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
2160 • Avoid an infinite busy-loop if a signal interrupts waitpid()
2161 (fd.o #68945, Simon McVittie)
2163 • Clean up memory for parent nodes when objects are unexported
2164 (fd.o #60176, Thomas Fitzsimmons)
2166 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
2167 documented. Previously, it assumed its second parameter was TRUE.
2168 (fd.o #69165, Chengwei Yang)
2170 • Escape addresses containing non-ASCII characters correctly
2171 (fd.o #53499, Chengwei Yang)
2173 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
2175 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
2176 (fd.o #65923, Chengwei Yang)
2178 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
2179 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
2181 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
2182 that was never va_start()ed (fd.o #66300, Chengwei Yang)
2184 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
2186 • fix a regression test on platforms with strict alignment (fd.o #67279,
2189 • Avoid calling function parameters "interface" since certain Windows headers
2190 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
2192 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
2194 • Various thread-safety improvements to static variables (fd.o #68610,
2197 • Make "make -j check" work (fd.o #68852, Simon McVittie)
2199 • Fix a NULL pointer dereference on an unlikely error path
2200 (fd.o #69327, Sviatoslav Chagaev)
2202 • Improve valgrind memory pool tracking (fd.o #69326,
2205 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
2208 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
2209 (fd.o #66107, Chengwei Yang)
2212 · If accept4() fails with EINVAL, as it can on older Linux kernels
2213 with newer glibc, try accept() instead of going into a busy-loop.
2214 (fd.o #69026, Chengwei Yang)
2215 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
2216 for instance on Hurd or older Linux with a new glibc, try without
2217 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)

2221 (fd.o #39196, Simon)
2222 · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang)
2223 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
2224 · Use dbus-launch from the builddir for testing, not the installed copy
2225 (fd.o #37849, Chengwei Yang)
2226 · Fix compilation if writev() is unavailable (fd.o #69409,
2228 · Remove broken support for LOCAL_CREDS credentials passing, and
2229 document where each credential-passing scheme is used (fd.o #60340,
2231 · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality
2232 (fd.o #35881, #69787; Chengwei Yang)

2257 D-Bus 1.7.4 (2013-06-13)
2260 The “but is your thread-safety thread-safe?” release.
2264 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
2265 of service for system services. Vulnerability reported by Alexandru Cornea.
2270 • The Windows version of libdbus now contains a C++ source file, used
2271 to provide global initialization when the library is loaded.
2272 gcc (mingw*) users should ensure that g++ is also installed.
2274 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
2275 and was never the recommended option) has been removed. Expat is now a
2280 • It should now be safe to call dbus_threads_init_default() from any thread,
2281 at any time. Authors of loadable modules and plugins that use libdbus
2282 should consider doing so during initialization.
2283 (fd.o #54972, Simon McVittie)
2285 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
2289 · dbus-run-session: experimental new tool to start a temporary D-Bus
2290 session, e.g. for regression tests or a text console, replacing
2291 certain uses of dbus-launch which weren't really correct
2292 (fd.o #39196, Simon)
2296 • In dbus-daemon, don't crash if a .service file starts with key=value
2297 (fd.o #60853, Chengwei Yang)
2300 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
2301 on a platform not defining LOG_PERROR, such as Solaris or QNX.
2302 This regressed in 1.7.0. (Simon)
2303 · Fix an assertion failure if we try to activate systemd services before
2304 systemd connects to the bus (fd.o #50199, Chengwei Yang)
2305 · Avoid compiler warnings for ignoring the return from write()
2309 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
2310 so that Windows finds them (fd.o #59733, Ralf Habacker)
2312 D-Bus 1.7.2 (2013-04-25)
2315 The “only partially opaque” release.
2317 Configuration changes:
2319 • On non-QNX Unix platforms, the default limit on fds per message in the
2320 session bus configuration has reduced from 4096 to 1024. The default
2321 limit used on the system bus was already 1024. On QNX, both limits are
2322 reduced further, to 128.
2326 • D-Bus Specification 0.21
2327 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
2328 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
2333 • Diagnose incorrect use of dbus_connection_get_data() with negative slot

2358 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,
2361 D-Bus 1.7.0 (2013-02-22)
2364 The "Disingenuous Assertions" release.
2366 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
2367 remains the recommended version for long-term-supported distributions
2368 or the upcoming GNOME 3.8 release.
2370 Build-time configuration changes:
2372 • The --with-dbus-session-bus-default-address configure option is no longer
2373 supported. Use the new --with-dbus-session-bus-connect-address and
2374 --with-dbus-session-bus-listen-address options instead. On Windows, you
2375 usually want them to have the same argument; on Unix, the defaults are
2378 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
2379 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
2380 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
2382 • cmake/cross-compile.sh has been removed. Instead, please use a
2383 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
2384 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
2385 as documented in "info automake Cross-Compilation", and set
2386 PKG_CONFIG_PATH appropriately.
2390 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
2391 • man2html is no longer used.
2395 • D-Bus Specification 0.20
2396 · actually say that /org/freedesktop/DBus is the object that
2397 implements o.fd.DBus (fd.o #51865, Colin Walters)
2398 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
2399 · stop claiming that all basic types work just like INT32 (strings don't!)
2401 • The "source code" for the man pages is now Docbook XML, eliminating
2402 the outdated duplicate copies used when building with CMake.
2403 (fd.o #59805; Ralf Habacker, Simon McVittie)
2407 • In the activation helper, when compiled for tests, do not reset the system
2408 bus address, fixing the regression tests. (fd.o #52202, Simon)
2410 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
2411 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
2413 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

2435 · The default session bus listening and connecting address is now
2436 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2437 and GDBus "out of the box". Use the configure options and cmake variables
2438 described above if you require a different autolaunch scope.
2439 (fd.o #38201, Simon McVittie)
2440 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
2442 • Create session.d, system.d directories under CMake (fd.o #41319,
2445 D-Bus 1.6.8 (2012-09-28)
2448 The "Fix one thing, break another" release.
2450 • Follow up to CVE-2012-3524: The additional hardening
2451 work to use __secure_getenv() as a followup to bug #52202
2452 broke certain configurations of gnome-keyring. Given
2453 the difficulty of making this work without extensive
2454 changes to gnome-keyring, use of __secure_getenv() is

2496 (fd.o #51032, Simon McVittie)
2498 • Disconnect "developer mode" (assertions, verbose mode etc.) from
2499 Automake maintainer mode. D-Bus developers should now configure with
2500 --enable-developer. Automake maintainer mode is now on by default;
2501 distributions can disable it with --disable-maintainer-mode.
2502 (fd.o #34671, Simon McVittie)
2504 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
2505 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
2508 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
2510 D-Bus 1.6.0 (2012-06-05)
2513 The “soul of this machine has improved” release.
2515 This version starts a new stable branch of D-Bus: only bug fixes will
2516 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
2518 Summary of changes since 1.4.x:

2557 Changes since 1.5.12:
2559 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
2560 spec-compliance (fd.o #48580, David Zeuthen)
2562 • Don't use install(1) within the source/build trees, fixing the build as
2563 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
2565 • Add missing commas in some tcp and nonce-tcp addresses, and remove
2566 an unused duplicate copy of the nonce-tcp transport in Windows builds
2567 (fd.o #45896, Simon McVittie)
2569 D-Bus 1.5.12 (2012-03-27)
2572 The “Big Book of Science” release.
2574 • Add public API to validate various string types:
2575 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
2576 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
2577 (fd.o #39549, Simon McVittie)
2579 • Turn DBusBasicValue into public API so bindings don't need to invent their
2580 own "union of everything" type (fd.o #11191, Simon McVittie)
2582 • Enumerate data files included in the build rather than using find(1)
2583 (fd.o #33840, Simon McVittie)

2590 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
2591 · fix duplicate case value when compiling against mingw-w64
2592 (fd.o #47321, Andoni Morales Alastruey)
2594 D-Bus 1.5.10 (2012-02-21)
2597 The "fire in Delerium" release.
2599 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2600 and SUSv2) is now required.
2602 • D-Bus Specification 0.19:
2603 · Formally define unique connection names and well-known bus names,
2604 and document best practices for interface, bus, member and error names,
2605 and object paths (fd.o #37095, Simon McVittie)
2606 · Document the search path for session and system services on Unix, and
2607 where they should be installed by build systems (fd.o #21620, fd.o #35306;
2609 · Document the systemd transport (fd.o #35232, Lennart Poettering)
2611 • Make dbus_threads_init() use the same built-in threading implementation
2612 as dbus_threads_init_default(); the user-specified primitives that it
2613 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
2615 • Allow all configured auth mechanisms, not just one (fd.o #45106,
2618 • Improve cmake build system (Ralf Habacker):
2619 · simplify XML parser dependencies (fd.o #41027)
2620 · generate build timestamp (fd.o #41029)
2621 · only create batch files on Windows
2622 · fix option and cache syntax
2623 · add help-options target
2624 · share dbus-arch-deps.h.in with autotools rather than having our
2625 own version (fd.o #41033)
2627 • Build tests successfully with older GLib, as found in e.g. Debian 6
2628 (fd.o #41219, Simon McVittie)
2630 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
2632 • Build documentation correctly if man2html doesn't support filenames on
2633 its command-line (fd.o #43875, Jack Nagel)
2635 • Improve test coverage. To get even more coverage, run the tests with
2636 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
2638 • Reduce the size of the shared library by moving functionality only used
2639 by dbus-daemon, tests etc. into their internal library and deleting
2640 unused code (fd.o #34976, #39759; Simon McVittie)
2642 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2643 setups where the default configuration must include <pidfile/> to avoid
2644 breaking traditional init, but the pid file is in fact unnecessary; use
2645 it under systemd to improve startup time a bit (fd.o #45520,
2648 • Optionally (if configured --with-valgrind) add instrumentation to debug
2649 libdbus and associated tools more meaningfully under Valgrind
2650 (fd.o #37286, Simon McVittie)
2652 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
2654 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
2656 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
2657 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
2658 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
2661 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
2665 · Replace our broken reimplementation of recursive mutexes, which has
2666 been broken since 2006, with an ordinary pthreads recursive mutex
2667 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2668 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2669 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2670 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2671 · When running under systemd, use it instead of ConsoleKit to check
2672 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2673 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2674 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2675 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2676 (fd.o #41218, Simon McVittie)
2677 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2678 helper doesn't obey environment variables to avoid privilege escalation
2679 attacks, so make the system bus follow the same rules
2680 (fd.o #21620, Simon McVittie)
2683 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2684 Jesper Dam, Ralf Habacker)
2685 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
2688 D-Bus 1.5.8 (2011-09-21)

2693 In addition to dead code removal and refactoring, this release contains all
2694 of the bugfixes from 1.4.16.
2696 • Clean up dead code, and make more warnings fatal in development builds
2697 (fd.o #39231, fd.o #41012; Simon McVittie)
2699 • If full test coverage is requested via --enable-tests, strictly require
2700 Python, pygobject and dbus-python, which are required by some tests; if not,
2701 and Python is missing, skip those tests rather than failing
2702 (fd.o #37847, Simon McVittie)
2704 • When using cmake, provide the same version-info API in the installed headers
2705 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2707 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
2709 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)

2714 • Fix duplicates in authors list (Ralf Habacker)
2716 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2717 (fd.o #39879, Chris Mayo)
2719 • Fix a small memory leak, and a failure to report errors, when updating
2720 a service file entry for activation (fd.o #39230, Simon McVittie)
2723 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2724 Brian Cameron, Simon McVittie)
2725 · On systems that use libcap-ng but not systemd, drop supplemental groups
2726 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2727 · Make the cmake build work again on GNU platforms (fd.o #29228,
2729 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
2730 like Solaris (fd.o #40313, Dagobert Michelsen)
2731 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2732 (fd.o #40235, Simon McVittie)
2733 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2734 (fd.o #39987, Simon McVittie)
2735 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2736 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2739 · Fix compilation on MSVC, which doesn't understand "inline" with its
2740 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2741 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2742 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2744 D-Bus 1.5.6 (2011-07-29)
2747 The "weird, gravy-like aftertaste" release.
2749 In addition to new features and refactoring, this release contains all of the
2750 bugfixes from 1.4.14.
2752 Potentially incompatible (Bustle and similar debugging tools will need
2753 changes to work as intended):
2755 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2756 different recipient) by mistake: eavesdroppers must now opt-in to this
2757 behaviour by putting "eavesdrop='true'" in the match rule, which will
2758 not have any practical effect on buses where eavesdropping is not allowed
2759 (fd.o #37890, Cosimo Alfarano)
2763 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2764 Cosimo Alfarano, Simon McVittie)
2765 · add the "eavesdrop" keyword to match rules
2766 · define eavesdropping, unicast messages and broadcast messages
2767 · stop claiming that match rules are needed to match unicast messages to you
2768 · promote the type system to be a top-level section
2770 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2771 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2772 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2774 • Consistently use atomic operations on everything that is ever manipulated
2775 via atomic ops, as was done for changes to DBusConnection's refcount in
2776 1.4.12 (fd.o #38005, Simon McVittie)
2778 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2781 • Make "make check" in a clean tree work, by not running tests until
2782 test data has been set up (fd.o #34405, Simon McVittie)
2784 • The dbus-daemon no longer busy-loops if it has a very large number of file
2785 descriptors (fd.o #23194, Simon McVittie)
2787 • Refactor message flow through dispatching to avoid locking violations if
2788 the bus daemon's message limit is hit; remove the per-connection link cache,
2789 which was meant to improve performance, but now reduces it (fd.o #34393,
2792 • Some cmake fixes (Ralf Habacker)
2794 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2795 Simon McVittie, Lennart Poettering)
2797 • Stop storing two extra byte order indicators in each D-Bus message
2798 (fd.o #38287, Simon McVittie)
2800 • Add an optional Stats interface which can be used to get statistics from
2801 a running dbus-daemon if enabled at configure time with --enable-stats
2802 (fd.o #34040, Simon McVittie)
2804 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2806 • Documentation (fd.o #36156, Simon McVittie):
2807 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2808 · install more documentation automatically, including man2html output
2809 · put dbus.devhelp in the right place (it must go in ${htmldir})
2812 · look for system services in /lib/dbus-1/system-services in addition to all
2813 the other well-known locations; note that this should always be /lib,
2814 even on platforms where shared libraries on the root FS would go in /lib64,
2815 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2816 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2818 • Windows-specific (Ralf Habacker):
2819 · fix use of a mutex for autolaunch server detection
2820 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2822 D-Bus 1.5.4 (2011-06-10)
2825 Security (local denial of service):
2827 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2828 local DoS if foreign-endian messages are relayed through the dbus-daemon
2829 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2830 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2834 • The constant to use for an infinite timeout now has a name,
2835 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2836 which can be used for source compatibility with older versions of libdbus.
2838 • If GLib and DBus-GLib are already installed, more tests will be built,
2839 providing better coverage. The new tests can also be installed via
2840 ./configure --enable-installed-tests
2841 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2845 • Consistently use atomic operations for the DBusConnection's refcount,
2846 fixing potential threading problems (fd.o #38005, Simon McVittie)
2848 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2849 small (300KiB on x86-64) and it frequently doesn't work in unusual
2850 toolchains. To optimize for minimum installed size, you should benchmark
2851 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2852 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2854 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2855 (fd.o #35880, Timothy Redaelli)
2857 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2858 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2860 • Windows-specific changes:
2861 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2863 D-Bus 1.5.2 (2011-06-01)
2866 The "Boar Hunter" release.
2868 Notes for distributors:
2870 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2871 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2872 toolchain supports it reliably, via something like:
2874 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2876 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2880 • D-Bus Specification v0.17

2885 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2886 • Allow --disable-gc-sections, in case your toolchain offers the
2887 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2888 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2889 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2890 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2891 • Ensure that maintainers upload documentation with the right permissions
2892 (fd.o #36130, Simon McVittie)

2900 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
2901 (fd.o #35228, Lennart Poettering)
2902 • In the regression tests, don't report fds as "leaked" if they were open
2903 on startup (fd.o #35173, Simon McVittie)
2904 • Make dbus-monitor bail out if asked to monitor more than one bus,
2905 rather than silently using the last one (fd.o #26548, Will Thompson)
2906 • Clarify documentation (fd.o #35182, Simon McVittie)
2907 • Clean up minor dead code and some incorrect error handling

2922 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
2923 · Make argNpath support object paths, not just object-path-like strings,
2924 and document it better (fd.o #31818, Will Thompson)
2925 • Let the bus daemon implement more than one interface (fd.o #33757,
2927 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2929 • Require user intervention to compile with missing 64-bit support
2930 (fd.o #35114, Simon McVittie)
2931 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
2932 • Raise UnknownObject instead of UnknownMethod for calls to methods on
2933 paths that are not part of the object tree, and UnknownInterface for calls
2934 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
2936 D-Bus 1.4.8 (2011-04-08)
2939 The "It's like the beginning of a lobster" release.
2941 • Rename configure.in to configure.ac, and update it to modern conventions
2942 (fd.o #32245; Javier Jardón, Simon McVittie)
2943 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
2945 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
2946 --disable-x11-autolaunch configure option to prevent it altogether
2947 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
2948 • Install the documentation, and an index for Devhelp (fd.o #13495,
2949 Debian #454142; Simon McVittie, Matthias Clasen)
2950 • If checks are not disabled, check validity of string-like types and
2951 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
2952 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
2953 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
2954 • Break up a huge conditional in config-parser so gcov can produce coverage
2955 data (fd.o #10887, Simon McVittie)
2956 • List which parts of the Desktop Entry specification are applicable to
2957 .service files (fd.o #19159, Sven Herzberg)
2958 • Don't suppress service activation if two services have the same Exec=

2969 The "1, 2, miss a few, 99, 100" release.
2971 • Remove unfinished changes intended to support GTest-based tests,
2972 which were mistakenly included in 1.4.4
2974 D-Bus 1.4.4 (2010-02-17)
2977 • Switch back to using even micro versions for stable releases; 1.4.1
2978 should have been called 1.4.2, so skip that version number
2979 • Don't leave bad file descriptors being watched when spawning processes,
2980 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
2981 also LP#656134, LP#680444, LP#713157)
2982 • Check for MSG_NOSIGNAL correctly

3016 crash the bus. The existing restriction to 64-levels of nesting previously
3017 only applied to the static type signature; now it also applies to dynamic
3018 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
