1 D-Bus 1.11.16 (UNRELEASED)
4 Build-time configuration changes:
6 • The Autotools build system now supports varying ${runstatedir}
7 independently of ${localstatedir}, if using an Autoconf version
8 that has that feature; version 2.70 will eventually have this, but
9 many Linux distributions add it to version 2.69 as a patch.
10 A typical use is to set prefix=/usr, sysconfdir=/etc, localstatedir=/var
11 and runstatedir=/run. (fd.o #101569, Simon McVittie)
15 • New APIs DBUS_MESSAGE_ITER_INIT_CLOSED, dbus_message_iter_init_closed()
16 and dbus_message_iter_abandon_container_if_open() simplify the
17 single-exit-point ("goto out") style of resource cleanup. The API
18 documentation around DBusMessageIter and containers has also been
19 clarified. (fd.o #101568, Simon McVittie)
23 • Make the dbus-daemon's Properties interface, as introduced in 1.11.14,
24 available to all users on the system bus (fd.o #101700, Simon McVittie)
26 • dbus_message_iter_append_basic() no longer leaks memory if it fails to
27 append a file descriptor to a message. (fd.o #101568, Simon McVittie)
29 • dbus_message_iter_open_container() no longer leaks memory if it runs out
30 of memory. (fd.o #101568, Simon McVittie)
32 • dbus_message_append_args_valist() no longer leaks memory if given an
33 unsupported type. This situation is still considered to be a programming
34 error which needs to be corrected by the user of libdbus.
35 (fd.o #101568, Simon McVittie)
37 • dbus_message_iter_append_basic() and dbus_message_iter_open_container()
38 will no longer report that their arguments were invalid if they run out
39 of memory at exactly the wrong time. (fd.o #101568, Simon McVittie)
41 • Ensure that tests fail if they would otherwise have tried to connect to
42 the real session bus (fd.o #101698, Simon McVittie)
44 • Make build-time tests cope with finding Python 3, but not Python 2
45 (fd.o #101716, Simon McVittie)
47 Internal changes relevant to dbus developers:
49 • DBusVariant is a new mechanism to copy single values from a message into
50 a buffer without copying the entire message (fd.o #101568, Simon McVittie)
52 • DBUS_SYSTEM_LOG_FATAL has been replaced by DBUS_SYSTEM_LOG_ERROR.
53 Logging an ERROR message does not make the process exit; the caller
54 is responsible for calling abort() or exit(), whichever is more appropriate.
55 (fd.o #101568, Simon McVittie)
57 • Better test coverage (fd.o #101568, Simon McVittie)
59 D-Bus 1.11.14 (2017-06-29)
62 The “irrational fear of bees” release.
66 • Expat >= 2.1.0 is always required
67 • libselinux >= 2.0.86 is required if SELinux support is enabled
68 • GLib >= 2.40 is required if full test coverage is enabled
70 Build-time configuration changes:
72 • We now use pkg-config to find libexpat in Autotools builds. This requires
73 Expat 2.1.0 (March 2012) or later. In particular, this should remove the
74 need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
75 itself cause compilation failures.
77 As with all pkg-config-based configure checks, you can use
78 PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
79 non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
80 EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
83 (fd.o #69801, Simon McVittie)
85 • Similarly, we now use pkg-config to find libselinux. Version 2.0.86
86 is required due to the removal of explicit refcounting for SIDs.
87 (fd.o #100912, Laurent Bigonville)
91 • Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
92 as a side-effect of a sufficiently privileged process merely reading the
93 machine ID. It is no longer copied as a side-effect of reading.
94 Running dbus-uuidgen --ensure, which should be done after installing dbus,
95 continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
96 former exists and the latter does not.
97 (fd.o #101257, Simon McVittie)
99 • The undocumented Verbose interface, and the GetAllMatchRules method on
100 the undocumented Stats interface, must now be used via the object path
101 /org/freedesktop/DBus. Previously, they existed on all object paths.
102 (fd.o #101257, Simon McVittie)
104 • AddMatch() with a match rule containing eavesdrop='true' will now fail
105 unless called by either the same user as the dbus-daemon, or Unix uid 0
106 (root), matching the restrictions applied to the newer BecomeMonitor()
107 method. On the session bus this has no practical effect. On the system
108 bus this will prevent certain configurations that already did not
109 work well in practice. (fd.o #101567, Simon McVittie)
113 • D-Bus Specification version 0.31
114 · Don't require implementation-specific search paths to be lowest
116 · Correct regex syntax for optionally-escaped bytes in addresses so it
117 includes hyphen-minus, forward slash and underscore as intended
118 · Describe all message bus methods in the same section
119 · Clarify the correct object path for method calls to the message bus
120 (/org/freedesktop/DBus, DBUS_PATH_DBUS in the reference implementation)
121 · Document that the message bus implements Introspectable, Peer and
123 · Add new Features and Interfaces properties for message bus
125 · Add unix:dir=..., which resembles unix:tmpdir=... but never uses
127 · Don't require eavesdrop='true' to be accepted from connections not
128 sufficiently privileged to use it successfully
129 · Formally deprecate eavesdropping in favour of BecomeMonitor
130 (fd.o #99825, #100686, #100795, #101256, #101257, #101567;
131 Simon McVittie, Tom Gundersen)
133 • Implement the Properties and Peer interfaces in dbus-daemon
134 (fd.o #101257, Simon McVittie)
136 • New function dbus_try_get_local_machine_id() is like
137 dbus_get_local_machine_id(), but returning a DBusError. Other code
138 that needs the machine ID will now report a recoverable error (instead
139 of logging to stderr and aborting) if no machine ID is available.
140 Generating a machine ID is still considered to be a required part of
141 installing dbus correctly. (fd.o #13194, Simon McVittie)
143 • Implement GetConnectionSELinuxSecurityContext("org.freedesktop.DBus")
144 (fd.o #101315, Laurent Bigonville)
146 • Avoid deprecated API calls when using SELinux
147 (fd.o #100912, Laurent Bigonville)
149 • Switch a test from the deprecated g_test_trap_fork() to
150 g_test_trap_subprocess(), for Windows support and better robustness
151 on Unix (fd.o #101362, Simon McVittie)
153 • On systemd systems, if ${localstatedir}/dbus/machine-id doesn't exist,
154 instruct systemd-tmpfiles to make it a symbolic link to /etc/machine-id.
155 This prevents the two files from going out of sync on stateless or live
156 images without needing to run dbus-uuidgen, and supports older D-Bus
157 implementations that do not necessarily read /etc/machine-id themselves.
158 (fd.o #101570, Simon McVittie)
160 • Implement unix:dir=..., which resembles unix:tmpdir=... but never uses
161 abstract sockets. This is preferable when used with Linux containers.
162 (fd.o #101567, Simon McVittie)
166 • Fix a reference leak when blocking on a pending call on a connection
167 that has been disconnected (fd.o #101481, Shin-ichi MORITA)
169 • Don't put timestamps in the Doxygen-generated documentation,
170 or hard-code the build directory into builds with embedded tests,
171 for reproducible builds (fd.o #100692, Simon McVittie)
173 • Fix some integration test issues (fd.o #100686, Simon McVittie)
175 • Fix memory leaks in the tests (fd.o #101257, Simon McVittie)
177 • If we somehow get an autolaunch address with multiple semicolon-separated
178 components, and they don't work, don't invalidly "pile up" errors
179 (fd.o #101257, Simon McVittie)
183 • Update git URIs in HACKING document to sync up with cgit.freedesktop.org
184 (fd.o #100715, Simon McVittie)
186 D-Bus 1.11.12 (2017-04-07)
189 The “it's something humans do” release.
193 • The session dbus-daemon now supports transient .service files
194 in $XDG_RUNTIME_DIR/dbus-1/services. Unlike the other standard
195 service directories, this directory is not monitored with inotify
196 or similar, and the service files must be named exactly
197 ${bus_name}.service. (fd.o #99825, Simon McVittie)
199 • dbus can be configured with --enable-relocation when building with
200 Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
201 to make the pkg-config metadata relocatable. This is useful for
202 non-standard prefixes, and in particular for Windows installations.
203 However, it is not recommended for system-wide installations into
204 /usr, because it interferes with pkg-config's ability to filter out
205 compiler default linker directories.
207 With Autotools, the default is --enable-relocation when building
208 for Windows or --disable-relocation otherwise. With CMake, the default
209 is -DDBUS_RELOCATABLE=ON.
211 (fd.o #99721; Ralf Habacker, Simon McVittie)
213 • Users of CMake ≥ 2.6 can now link to libdbus without providing their
214 own FindDBus.cmake macros, whether dbus was compiled with Autotools
215 or with CMake. See the end of README.cmake for more information.
216 (fd.o #99721; Ralf Habacker, Simon McVittie)
220 • Always read service file directories in the intended order
221 (fd.o #99825, Simon McVittie)
223 • When tests are skipped, don't try to kill nonexistent process 0
224 (fd.o #99825, Simon McVittie)
226 • Avoid valgrind false positives (fd.o #88808, Philip Withnall)
228 • Fix a harmless read overflow and some memory leaks in a unit test
229 (fd.o #100568, Philip Withnall)
231 • Fix some typos in test code
232 (fd.o #99999, Coverity #141876, #141877; Philip Withnall)
234 • Clarify the roles of /etc/dbus-1/s*.d and /usr/share/dbus-1/s*.d
235 in documentation (fd.o #99901, Philip Withnall)
237 • Fix and enable compiler warnings related to -Wswitch
238 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
240 • Fix writing off the end of a fd_set when testing with valgrind
241 (fd.o #99839, Philip Withnall)
243 D-Bus 1.11.10 (2017-02-16)
246 The “purple hair gives you telekinesis?” release.
250 • AppArmor support requires at least libapparmor 2.8.95, reduced
251 from 2.10 in previous versions. One test requires 2.10 and is
252 skipped if building with an older version.
256 • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian
257 stable and Debian testing in addition to the older Ubuntu that is
258 the default (fd.o #98889, Simon McVittie)
260 • Avoid some deprecated CMake functions (fd.o #99586, Ralf Habacker)
262 • Silence many -Wswitch-enum and -Wswitch-default warnings
263 (fd.o #98191; Thomas Zimmermann, Simon McVittie)
265 • Install a sysusers.d snippet so `dbus-daemon --system` can be used
266 with an unpopulated /etc (fd.o #99162, Lennart Poettering)
268 • Install pkg-config metadata on Unix even if building with CMake
269 (fd.o #99752, Ralf Habacker)
271 • Exclude auth mechanisms from REJECTED message if they are supported
272 in the code but but configured to be disallowed (fd.o #99621,
277 • Prevent symlink attacks in the nonce-tcp transport on Unix that could
278 allow an attacker to overwrite a file named "nonce", in a directory
279 that the user running dbus-daemon can write, with a random value
280 known only to the user running dbus-daemon. This is unlikely to be
281 exploitable in practice, particularly since the nonce-tcp transport
282 is really only useful on Windows.
284 On Unix systems we strongly recommend using only the unix: and systemd:
285 transports, together with EXTERNAL authentication. These are the only
286 transports and authentication mechanisms enabled by default.
288 (fd.o #99828, Simon McVittie)
290 • Avoid symlink attacks in the "embedded tests", which are not enabled
291 by default and should never be enabled in production builds of dbus.
292 (fd.o #99828, Simon McVittie)
294 • Fix the implementation of re-enabling a timeout so that its
295 countdown is restarted as intended, instead of continually
296 decreasing. (fd.o #95619; Michal Koutný, Simon McVittie)
298 • When receiving a message with file descriptors, do not start reading
299 the beginning of the next message, so that only one such message
300 is processed at a time. In conjunction with the fix for #95619
301 this means that processes sending many file descriptors, such as
302 systemd-logind on a system that receives very rapid ssh connections,
303 are not treated as abusive and kicked off the bus. Revert the previous
304 workaround that special-cased uid 0.
305 (fd.o #95263, LP#1591411; Simon McVittie)
307 • Do not require TMPDIR, TEMP or TMP to be set when cross-compiling
308 for Windows with CMake (fd.o #99586, Ralf Habacker)
310 • Do not set Unix-specific variables when targeting Windows
311 (fd.o #99586, Ralf Habacker)
313 • Install Unix executables to ${CMAKE_INSTALL_PREFIX}/bin as intended,
314 not ${CMAKE_INSTALL_PREFIX}/lib (fd.o #99752, Ralf Habacker)
316 • Use relative install locations in CMake on Unix to respect DESTDIR,
317 and use GNU-style install layout (fd.o #99721, #99752; Ralf Habacker)
319 • Install dbus-arch-deps.h correctly when using CMake
320 (fd.o #99586, #99721; Ralf Habacker)
322 • Improve argument validation for `dbus-test-tool spam`
323 (ffd.o #99693, Coverity #54759; Philip Withnall)
325 • Don't shift by a negative integer if a hash table becomes monstrously
326 large (fd.o #99641, Coverity #54682; Philip Withnall)
328 • Don't leak LSM label if dbus-daemon runs out of memory when dealing with
329 a new connection (fd.o #99612, Coverity #141058; Philip Withnall)
331 • Remove an unnecessary NULL check
332 (fd.o #99642, Coverity #141062; Philip Withnall)
334 • Improve error handling in unit tests and dbus-send
335 (fd.o #99643, #99694, #99712, #99722, #99723, #99724, #99758,
336 #99759, #99793, Coverity #54688, #54692, #54693, #54697, #54701,
337 #54710, #54711, #54714, #54715, #54718, #54721, #54724, #54726,
338 #54730, #54740, #54822, #54823, #54824, #54825; Philip Withnall)
340 • Do not print verbose messages' timestamps to stderr if the actual message
341 has been redirected to the Windows debug port (fd.o #99749, Ralf Habacker)
343 D-Bus 1.11.8 (2016-11-28)
346 The “panics in the face of breakfast foods” release.
348 Build-time configuration:
350 • The new --enable-debug configure option provides an easy way to
351 enable debug symbols, disable optimization and/or enable profiling.
353 • The --enable-compile-warnings configure option can be used to control
356 • The --disable-compiler-optimisations configure option is no longer
357 supported. Use --enable-debug=yes or CFLAGS=-O0 instead.
361 • D-Bus Specification version 0.30
362 · Define the jargon term "activation" more clearly
363 · Define the jargon term "auto-starting", which is one form of activation
364 · Document the optional SystemdService key in service files
365 · Use versioned interface and bus names in most examples
366 · Clarify intended behaviour of Properties.GetAll
367 (fd.o #36190, fd.o #98671; Philip Withnall, Simon McVittie)
369 • Fix and enable a lot of compiler warnings to improve future code
370 quality. This might incidentally also fix some environment variable
372 · In particular, printf-style functions in the libdbus API are now annotated
373 with __attribute__((__format__(__printf__, *, *))) when compiling with
374 gcc or clang. This might make printf bugs in other software visible
376 (fd.o #97357, fd.o #98192, fd.o #98195, fd.o #98658;
377 Thomas Zimmermann, Simon McVittie)
379 • When running with AppArmor mediation (for example using Ubuntu's patched
380 Linux kernel), clients can no longer auto-start services unless they would
381 have been able to send the auto-starting message to the service after it
382 starts. StartServiceByName() is unaffected, and continues to be allowed by
383 default in AppArmor's <abstractions/dbus-strict> and
384 <abstractions/dbus-session-strict>. (fd.o #98666, Simon McVittie)
388 • Work around an undesired effect of the fix for CVE-2014-3637
389 (fd.o #80559), in which processes that frequently send fds, such as
390 logind during a flood of new PAM sessions, can get disconnected for
391 continuously having at least one fd "in flight" for too long;
392 dbus-daemon interprets that as a potential denial of service attack.
393 The workaround is to disable that check for uid 0 process such as
394 logind, with a message in the system log. The bug remains open while
395 we look for a more general solution.
396 (fd.o #95263, LP#1591411; Simon McVittie)
398 • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching
399 was disabled at compile time. That test is not expected to work
400 in that configuration. (fd.o #98665, Simon McVittie)
402 D-Bus 1.11.6 (2016-10-10)
405 The “darkly whimsical” release.
409 • Do not treat ActivationFailure message received from root-owned systemd
410 name as a format string. In principle this is a security vulnerability,
411 but we do not believe it is exploitable in practice, because only
412 privileged processes can own the org.freedesktop.systemd1 bus name, and
413 systemd does not appear to send activation failures that contain "%".
415 Please note that this probably *was* exploitable in dbus versions
416 older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at
417 the time was only thought to be a denial of service vulnerability
418 (CVE-2015-0245). If you are still running one of those versions,
419 patch or upgrade immediately.
421 (fd.o #98157, Simon McVittie)
425 • D-Bus Specification version 0.29
426 · Recommend not using '/' for object paths (fd.o #37095, Philip Withnall)
427 · Allow <annotation> in <arg> elements (fd.o #86162, Philip Withnall)
429 • Log to syslog when we exceed various anti-DoS limits, and add test
430 coverage for them (fd.o #86442, Simon McVittie)
432 • Improve syslog handling so that _dbus_warn() and similar warnings
433 go to syslog, add dbus-daemon --syslog|--nosyslog|--syslog-only options,
434 and log to syslog (instead of /dev/null) when dbus-daemon is started by
435 dbus-launch. (fd.o #97009, Simon McVittie)
437 • Install introspect.dtd and busconfig.dtd to ${datadir}/xml/dbus-1
438 (fd.o #89011, Philip Withnall)
440 • When logging messages about service activation, mention which peer
441 requested the activation (fd.o #68212, Philip Withnall)
443 • On Linux, mention the LSM label (if available) whenever we print
444 debug information about a peer (fd.o #68212, Philip Withnall)
448 • Harden dbus-daemon against malicious or incorrect ActivationFailure
449 messages by rejecting them if they do not come from a privileged
450 process, or if systemd activation is not enabled
451 (fd.o #98157, Simon McVittie)
453 • Avoid undefined behaviour when setting reply serial number without going
454 via union DBusBasicValue (fd.o #98035, Marc Mutz)
456 • Fix CMake build for Unix platforms that do not have -lrt, such as Android,
457 or that do need -lsocket, such as QNX (fd.o #94096, Ralf Habacker)
459 • autogen.sh: fail cleanly if autoconf fails (Simon McVittie)
461 D-Bus 1.11.4 (2016-08-15)
464 The “copper pickaxe” release.
468 • Building from git (but not from tarballs) now requires
469 macros from the GNU Autoconf Archive, for example the autoconf-archive
470 package in Debian or Fedora derivatives.
472 Build-time configuration:
474 • The option to enable coverage instrumentation has changed from
475 --enable-compiler-coverage to --enable-code-coverage.
479 • D-Bus Specification version 0.28
480 · Clarify some details of serialization (fd.o #93382, Philip Withnall)
482 • Increase listen() backlog of AF_UNIX sockets to the maximum possible,
483 minimizing failed connections under heavy load
484 (fd.o #95264, Lennart Poettering)
486 • Add a new dbus-launch --exit-with-x11 option (fd.o #39197, Simon McVittie)
488 • Use the same regression tests for subprocess starting on Unix and Windows
489 (fd.o #95191, Ralf Habacker)
491 • Print timestamps and thread IDs in verbose messages
492 (fd.o #95191, Ralf Habacker)
494 • On Unix, unify the various places that reopen stdin, stdout and/or stderr
495 pointing to /dev/null (fd.o #97008, Simon McVittie)
497 • Use AX_CODE_COVERAGE instead of our own COMPILER_COVERAGE
498 (fd.o #88922, Thomas Zimmermann)
502 • On Windows, fix a memory leak in replacing the installation prefix
503 (fd.o #95191, Ralf Habacker)
505 • On Linux, when dbus-daemon is run with reduced susceptibility to the
506 OOM killer (typically via systemd), do not let child processes inherit
507 that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho)
509 • On Unix, make dbus-launch and dbus-daemon --fork work as intended
510 even if a parent process incorrectly starts them with stdin, stdout
511 and/or stderr closed (fd.o #97008, Simon McVittie)
513 • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address
514 contains a semicolon (fd.o #94746, Thiago Macieira)
516 • Fix memory leaks and thread safety in subprocess starting on Windows
517 (fd.o #95191, Ralf Habacker)
519 • Stop test-dbus-daemon incorrectly failing on platforms that cannot
520 discover the process ID of clients (fd.o #96653, Руслан Ижбулатов)
522 • In tests that exercise correct handling of crashing D-Bus services,
523 suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker)
525 • Explicitly check for stdint.h (Ioan-Adrian Ratiu)
527 • In tests, add an invalid DBusAuthState to avoid undefined behaviour
528 in some test cases (fd.o #93909, Nick Lewycky)
530 • Add assertions to reassure a static analysis tool
531 (fd.o #93210, Deepika Aggarwal)
533 • Be explicit about enum comparison when loading XML
534 (fd.o #93205, Deepika Aggarwal)
536 • update-activation-environment: produce better diagnostics on error
537 (fd.o #96653, Simon McVittie)
539 • Avoid various compiler warnings with gcc 6
540 (fd.o #97282; Thomas Zimmermann, Simon McVittie)
542 • On Unix when configured to use the system log, report as "dbus-daemon",
543 not as "dbus" (fd.o #97009, Simon McVittie)
545 • During unit tests, reduce the amount we write to the system log
546 (fd.o #97009, Simon McVittie)
548 D-Bus 1.11.2 (2016-03-07)
551 The “pneumatic drill vs. Iron Maiden” release.
555 • Enable "large file support" on systems where it exists: dbus-daemon
556 is not expected to open large files, but it might need to stat files
557 that happen to have large inode numbers (fd.o #93545, Hongxu Jia)
559 • Eliminate padding inside DBusMessageIter on 64-bit platforms,
560 which might result in a pedantic C compiler not copying the entire contents
561 of a DBusMessageIter; statically assert that this is not an ABI change
562 in practice (fd.o #94136, Simon McVittie)
564 • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N
565 (fd.o #94244, Dmitri Iouchtchenko)
567 • Correctly report test failures in C tests from run-test.sh
568 (fd.o #93379; amit tewari, Simon McVittie)
570 • When tests are enabled, run all the marshal-validate tests, not just
571 the even-numbered ones (fd.o #93908, Nick Lewycky)
573 • Correct the expected error from one marshal-validate test, which was
574 previously not run due to the above bug (fd.o #93908, Simon McVittie)
576 • Fix compilation under CMake when embedded tests are disabled
577 (fd.o #94094, eric.hyer)
581 • Fix all -Wpointer-sign (signed/unsigned mismatch) warnings, and enable the
582 warning (fd.o #93069; Ralf Habacker, Simon McVittie)
584 • When building with CMake, use the same gcc/clang warnings as under Autotools,
585 or MSVC warnings that are broadly similar (fd.o #93069, Ralf Habacker)
587 • test/name-test: make C tests produce TAP output and run them directly, not
588 via run-test.sh (fd.o #92899, Simon McVittie)
590 • Under CMake when cross-compiling for Windows on Unix, run the tests
591 under Wine even if binfmt_misc support is not available
592 (fd.o #88966, Ralf Habacker)
594 • The DBUS_USE_TEST_BINARY environment variable is no longer used by builds with
595 embedded tests; DBUS_TEST_DBUS_LAUNCH replaces it (fd.o #92899, Simon McVittie)
597 • Factor out some functions that will be needed in future for a Windows
598 implementation of dbus-run-session (fd.o #92899, Ralf Habacker)
600 D-Bus 1.11.0 (2015-12-02)
603 The “peppermint deer” release.
607 • On non-Windows platforms, dbus now requires an <inttypes.h> that defines
608 C99 constants such as PRId64 and PRIu64.
612 • D-Bus Specification version 0.27
613 · Specify that services should not reply if NO_REPLY_EXPECTED was used
614 (fd.o #75749, Lars Uebernickel)
616 • Add a script to do continuous-integration builds, and metadata to run it
617 on travis-ci.org. To use this, clone the dbus git repository on GitHub
618 and set it up with travis-ci.org; the only special setting needed is
619 "only build branches with a .travis.yml". (fd.o #93194, Simon McVittie)
621 • If dbus-daemon is run with --systemd-activation, do not require
622 org.freedesktop.systemd1.service to exist (fd.o #93194, Simon McVittie)
626 • Re-order dbus-daemon startup so that on SELinux systems, the thread
627 that reads AVC notifications retains the ability to write to the
628 audit log (fd.o #92832, Laurent Bigonville)
630 • Print 64-bit integers on non-GNU Unix platforms (fd.o #92043, Natanael Copa)
632 • When using the Monitoring interface, match messages' destinations
633 (fd.o #92074, Simon McVittie)
635 • On Linux with systemd, stop installing a reference to the obsolete
636 dbus.target, and enable dbus.socket statically (fd.o #78412, #92402;
639 • On Windows, when including configuration files with <include> or
640 <includedir>, apply the same relocation as for the Exec paths
641 in .service files (fd.o #92028, Simon McVittie)
643 • Add support for backtraces on Windows (fd.o #92721, Ralf Habacker)
645 • Fix many -Wpointer-sign warnings (fd.o #93069, Ralf Habacker)
647 D-Bus 1.10.6 (2015-12-01)
650 The “marzipan beetles” release.
654 • On Unix when running tests as root, don't assert that root and
655 the dbus-daemon user can still call UpdateActivationEnvironment;
656 assert that those privileged users can call BecomeMonitor instead
657 (fd.o #93036, Simon McVittie)
659 • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899,
662 • On Windows Autotools builds, don't run tests that rely on
663 dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie)
665 D-Bus 1.10.4 (2015-11-17)
668 The “Frostburn Canyon” release.
672 • GetConnectionCredentials, GetConnectionUnixUser and
673 GetConnectionUnixProcessID with argument "org.freedesktop.DBus"
674 will now return details of the dbus-daemon itself. This is required
675 to be able to call SetEnvironment on systemd.
676 (fd.o #92857, Jan Alexander Steffens)
680 • Make UpdateActivationEnvironment always fail with AccessDenied on the
681 system bus. Previously, it was possible to configure it so root could
682 call it, but the environment variables were not actually used,
683 because the launch helper would discard them.
684 (fd.o #92857, Jan Alexander Steffens)
686 • On Unix with --systemd-activation on a user bus, make
687 UpdateActivationEnvironment pass on its arguments to systemd's
688 SetEnvironment method, solving inconsistency between the environments
689 used for traditional activation and systemd user-service activation.
690 (fd.o #92857, Jan Alexander Steffens)
692 • On Windows, don't crash if <syslog/> or --syslog is used
693 (fd.o #92538, Ralf Habacker)
695 • On Windows, fix a memory leak when setting a DBusError from a Windows
696 error (fd.o #92721, Ralf Habacker)
698 • On Windows, don't go into infinite recursion if we abort the process
699 with backtraces enabled (fd.o #92721, Ralf Habacker)
701 • Fix various failing tests, variously on Windows and cross-platform:
702 · don't test system.conf features (users, groups) that only make sense
703 on the system bus, which is not supported on Windows
704 · don't call _dbus_warn() when we skip a test, since it is fatal
705 · fix computation of expected <standard_session_servicedirs/>
706 · when running TAP tests, translate newlines to Unix format, fixing
707 cross-compiled tests under Wine on Linux
708 · don't stress-test refcounting under Wine, where it's really slow
709 · stop assuming that a message looped-back to the test will be received
711 · skip some system bus tests on Windows since they make no sense there
712 (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie)
714 D-Bus 1.10.2 (2015-10-26)
717 The “worst pies in London” release.
721 • Correct error handling for activation: if there are multiple attempts
722 to activate the same service and it fails immediately, the first attempt
723 would get the correct reply, but the rest would time out. We now send
724 the same error reply to each attempt. (fd.o #92200, Simon McVittie)
726 • If BecomeMonitor is called with a syntactically invalid match rule,
727 don't crash with an assertion failure, fixing a regression in 1.9.10.
728 This was not exploitable as a denial of service, because the check
729 for a privileged user is done first. (fd.o #92298, Simon McVittie)
731 • On Linux with --enable-user-session, add the bus address to the
732 environment of systemd services for better backwards compatibility
733 (fd.o #92612, Jan Alexander Steffens)
735 • On Windows, fix the logic for replacing the installation prefix
736 in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie)
738 • On Windows, if installed in the conventional layout with ${prefix}/etc
739 and ${prefix}/share, use relative paths between bus configuration files
740 to allow the tree to be relocated (fd.o #92028, Simon McVittie)
742 • Make more of the regression tests pass in Windows builds (fd.o #92538,
745 D-Bus 1.10.0 (2015-08-25)
750 This is a new stable branch, recommended for use in OS distributions.
754 • distribute test/tap-test.sh.in, even if the tarball was built without
755 tests enabled (fd.o #91684, Simon McVittie)
756 • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie)
758 Summary of major changes since 1.8.0:
760 • The basic setup for the well-known system and session buses is
761 now done in read-only files in ${datadir} (normally /usr/share).
762 See the NEWS entry for 1.9.18 for details.
764 • AppArmor integration has been merged, with features similar to the
765 pre-existing SELinux integration. It is mostly compatible with the
766 patches previously shipped by Ubuntu, with one significant change:
767 Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded
768 by GetConnectionCredentials and was not included.
770 • The --enable-user-session configure option can be enabled
771 by OS integrators intending to use systemd to provide a session bus
772 per user (in effect, treating all concurrent graphical and non-graphical
773 login sessions as one large session).
775 • The new listenable address mode "unix:runtime=yes" listens on
776 $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd
777 user session. libdbus and "dbus-launch --autolaunch" will connect to
778 this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a
781 • All executables are now dynamically linked to libdbus-1.
782 Previously, some executables, most notably dbus-daemon, were statically
783 linked to a specially-compiled variant of libdbus. This results in
784 various private functions in the _dbus namespace being exposed by the
785 shared library. These are not API, and must not be used outside
786 the dbus source tree.
788 • On platforms with ELF symbol versioning, all public symbols
789 are versioned LIBDBUS_1_3.
793 • org.freedesktop.DBus.GetConnectionCredentials returns
794 LinuxSecurityLabel where supported
795 • org.freedesktop.DBus.Monitoring interface (privileged)
796 · BecomeMonitor method supersedes match rules with eavesdrop=true,
797 which are now deprecated
798 • org.freedesktop.DBus.Stats interface (semi-privileged)
799 · now enabled by default
800 · new GetAllMatchRules method
801 • org.freedesktop.DBus.Verbose interface (not normally compiled)
802 · toggles the effect of DBUS_VERBOSE
807 • dbus-update-activation-environment
809 New optional dependencies:
811 • The systemd: pseudo-transport requires libsystemd or libsd-daemon
812 • Complete documentation requires Ducktype and yelp-tools
813 • Full test coverage requires GLib 2.36 and PyGI
814 • AppArmor integration requires libapparmor and optionally libaudit
816 Dependencies removed:
820 D-Bus 1.9.20 (2015-08-06)
823 The “Remember Tomorrow” release.
825 This is a release-candidate for D-Bus 1.10.0. OS distribution vendors
830 • Don't second-guess what the ABI of poll() is, allowing it to be used
831 on Integrity RTOS and other unusual platforms (fd.o #90314;
832 Rolland Dudemaine, Simon McVittie)
834 • Don't duplicate audit subsystem integration if AppArmor and SELinux are
835 both enabled (fd.o #89225, Simon McVittie)
837 • Log audit events for AppArmor/SELinux policy violations whenever
838 we have CAP_AUDIT_WRITE, even if not the system bus
839 (fd.o #83856, Laurent Bigonville)
841 D-Bus 1.9.18 (2015-07-21)
844 The “Pirate Elite” release.
846 Configuration changes:
848 • The basic setup for the well-known system and session buses is now done
849 in read-only files in ${datadir}, moving a step closer to systems
850 that can operate with an empty /etc directory. In increasing order
853 · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting
854 the default message policies.
855 · ${sysconfdir}/dbus-1/s*.conf are now optional. By default
856 dbus still installs a trivial version of each, for documentation
857 purposes; putting configuration directives in these files is deprecated.
858 · ${datadir}/dbus-1/s*.d/ are now available for third-party software
859 to install "drop-in" configuration snippets (any packages
860 using those directories should explicitly depend on at least this
862 · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins
863 or third-party software to install "drop-in" configuration snippets
864 · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins'
867 ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc,
868 and "s*" refers to either system or session as appropriate.
870 (fd.o #89280, Dimitri John Ledkov)
874 • Fix a memory leak when GetConnectionCredentials() succeeds
875 (fd.o #91008, Jacek Bukarewicz)
877 • Ensure that dbus-monitor does not reply to messages intended for others,
878 resulting in its own disconnection (fd.o #90952, Simon McVittie)
880 D-Bus 1.9.16 (2015-05-14)
883 The “titanium barns” release.
887 • Automake 1.13 is now required when compiling from git or modifying
892 • On Unix platforms, change the default configuration for the session bus
893 to only allow EXTERNAL authentication (secure kernel-mediated
894 credentials-passing), as was already done for the system bus.
896 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
897 unpredictable pseudo-random numbers.
899 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
900 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
901 NFS or similar, you will need to reconfigure the session bus to accept
902 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
905 (fd.o #90414, Simon McVittie)
907 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
908 transport, UUIDs or any other reason, fail if we cannot obtain entropy
909 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
910 occurs, instead of silently falling back to low-entropy pseudorandom
911 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
915 • Add dbus_message_iter_get_element_count()
916 (fd.o #30350; Christian Dywan, Simon McVittie)
918 • Introduce new internal DBusSocket and DBusPollable types so we can
919 stop treating the Windows SOCKET type as if it was int. DBusSocket
920 is specifically a socket, cross-platform. DBusPollable is whatever
921 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
922 (fd.o #89444; Ralf Habacker, Simon McVittie)
924 • All regression tests now output TAP <https://testanything.org/>
925 (fd.o #89846, Simon McVittie)
927 • Internal APIs consistently use signed values for timestamps
928 (fd.o #18494, Peter McCurdy)
930 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
931 (fd.o #88812, Simon McVittie)
933 • Clean up a lot of compiler warnings
934 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
938 • Add locking to DBusCounter's reference count and notify function
939 (fd.o #89297, Adrian Szyndela)
941 • Ensure that DBusTransport's reference count is protected by the
942 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
944 • Correctly release DBusServer mutex before early-return if we run out
945 of memory while copying authentication mechanisms (fd.o #90021,
948 • Make dbus-test-tool and dbus-update-activation-environment portable
949 to Windows (fd.o #90089, Ralf Habacker)
951 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
952 Ralf Habacker, Simon McVittie)
954 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
957 • Clean up some memory and fd leaks in test code and tools
958 (fd.o #90021, Ralf Habacker)
960 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
961 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
963 • CMake generates a versioned shared library even if the revision is 0,
964 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
966 D-Bus 1.9.14 (2015-03-02)
969 The “don't stand in the poison cloud” release.
973 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
974 were previously linked to a static version of libdbus.
976 • The tests no longer require dbus-glib in order to exercise the libdbus
977 shared library; they are always linked to libdbus now.
979 Build-time configuration:
981 • The new --enable-user-session option, off by default, can be enabled
982 by OS integrators intending to use systemd to provide a session bus
983 per user (in effect, treating all concurrent graphical and non-graphical
984 login sessions as one large session)
988 • All executables are now linked dynamically to libdbus.
989 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
991 • On platforms that support them (GNU libc and possibly others),
992 libdbus now has versioned symbols for its public API.
993 All public symbols (visible in the header files) are currently
994 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
995 dbus_internal have a version that changes with each release, and
996 must not be used by applications. (also fd.o #83115)
998 • New listenable address mode "unix:runtime=yes" which listens on
999 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
1000 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
1002 • Add optional systemd units for a per-user bus listening on
1003 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
1005 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
1006 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
1009 • New dbus-update-activation-environment tool uploads environment
1010 variables to "dbus-daemon --session" and optionally "systemd --user",
1011 primarily as a way to keep the per-user bus compatible with
1012 distributions' existing X11 login scripts (also fd.o #61301)
1014 • <includedir/> elements in dbus-daemon configuration are now silently
1015 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
1017 • Add microsecond-resolution timestamps to the default output of
1018 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
1022 • Fix a race condition in the 'monitor' test introduced in 1.9.10
1023 (fd.o #89222, Simon McVittie)
1025 D-Bus 1.9.12 (2015-02-19)
1028 The “monster lasagna” release.
1032 • Ducktype and yelp-tools are now required to build complete documentation
1033 (they are optional for normal builds).
1037 • D-Bus Specification version 0.26
1038 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
1039 · document the BecomeMonitor method
1041 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
1042 (fd.o #89041; Tyler Hicks, Simon McVittie)
1044 • On Linux, add support for AppArmor mediation of message sending and
1045 receiving and name ownership (paralleling existing SELinux mediation
1046 support), and eavesdropping (a new check, currently AppArmor-specific)
1047 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
1049 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
1050 that have printable ASCII contents; we previously only did this for
1051 unterminated bytestrings (fd.o #89109, Simon McVittie)
1053 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
1055 • On Windows, add WindowsSID to GetConnectionCredentials
1056 (fd.o #54445, Ralf Habacker)
1058 • Improve clarity of dbus-monitor --profile output and add more columns
1059 (fd.o #89165, Ralf Habacker)
1061 • Add a man page for dbus-test-tool, and build it under CMake as well
1062 as Autotools (fd.o#89086, Simon McVittie)
1064 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
1065 to control it at runtime, overriding the DBUS_VERBOSE environment variable
1066 (fd.o #88896, Ralf Habacker)
1070 • Reduce the number of file descriptors used in the fd-passing test,
1071 avoiding failure under the default Linux fd limit, and automatically
1072 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
1074 D-Bus 1.9.10 (2015-02-09)
1077 The “sad cyborgs” release.
1079 Security fixes merged from 1.8.16:
1081 • Do not allow non-uid-0 processes to send forged ActivationFailure
1082 messages. On Linux systems with systemd activation, this would
1083 allow a local denial of service: unprivileged processes could
1084 flood the bus with these forged messages, winning the race with
1085 the actual service activation and causing an error reply
1086 to be sent back when service auto-activation was requested.
1087 This does not prevent the real service from being started,
1088 so the attack only works while the real service is not running.
1089 (CVE-2015-0245, fd.o #88811; Simon McVittie)
1093 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
1094 similar tools receive messages without altering the security properties
1095 of the system bus, by calling the new BecomeMonitor method on a
1096 private connection. This bypasses the normal <allow> and <deny> rules
1097 entirely, so to preserve normal message-privacy assumptions, only root
1098 is allowed to do this on the system bus. Restricted environments,
1099 such as Linux with LSMs, should lock down access to the Monitoring
1100 interface. (fd.o #46787, Simon McVittie)
1102 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
1103 dbus-daemon supports it and access permissions allow it.
1104 It still supports the previous approach ("eavesdropping" match rules)
1105 for compatibility with older bus daemons. (fd.o #46787, Simon)
1107 • dbus-monitor can now log the message stream as binary data for later
1108 analysis, with either no extra framing beyond the normal D-Bus headers,
1109 or libpcap-compatible framing treating each D-Bus message
1110 as a captured packet. (fd.o #46787, Simon)
1114 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
1116 • On Unix, forcibly terminate regression tests after 60 seconds to
1117 prevent them from blocking continuous integration frameworks
1118 (fd.o #46787, Simon)
1120 D-Bus 1.9.8 (2015-02-03)
1123 The “all the types of precipitation” release.
1127 • full test coverage now requires GLib 2.36
1128 • full test coverage now requires PyGI (PyGObject 3,
1129 "import gi.repository.GObject") instead of the
1130 obsolete PyGObject 2 ("import gobject")
1134 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
1136 • better regression test coverage, including systemd activation
1137 (fd.o #57952, #88810; Simon McVittie)
1141 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
1142 turned off (fd.o #88808, Simon McVittie)
1144 • TCP sockets on Windows no longer fail to listen approximately 1 time
1145 in 256, caused by a logic error that should have always made it fail but
1146 was mitigated by incorrect endianness for the port number
1147 (fd.o #87999, Ralf Habacker)
1149 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
1151 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
1152 previous 64, completing a previous fix which only worked under
1153 Autotools (fd.o #71297, Ralf Habacker)
1155 • on Windows, if the IP family is unspecified only use IPv4,
1156 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
1158 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
1160 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
1162 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
1165 D-Bus 1.9.6 (2015-01-05)
1168 The “I do have a bread knife” release.
1172 • Do not allow calls to UpdateActivationEnvironment from uids other than
1173 the uid of the dbus-daemon. If a system service installs unsafe
1174 security policy rules that allow arbitrary method calls
1175 (such as CVE-2014-8148) then this prevents memory consumption and
1176 possible privilege escalation via UpdateActivationEnvironment.
1178 We believe that in practice, privilege escalation here is avoided
1179 by dbus-daemon-launch-helper sanitizing its environment; but
1180 it seems better to be safe.
1182 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
1183 on object paths other than /org/freedesktop/DBus. Some system services
1184 install unsafe security policy rules that allow arbitrary method calls
1185 to any destination, method and interface with a specified object path;
1186 while less bad than allowing arbitrary method calls, these security
1187 policies are still harmful, since dbus-daemon normally offers the
1188 same API on all object paths and other system services might behave
1193 • Add missing initialization so GetExtendedTcpTable doesn't crash on
1194 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
1196 D-Bus 1.9.4 (2014-11-24)
1199 The “extra-sturdy caramel” release.
1203 • Partially revert the CVE-2014-3639 patch by increasing the default
1204 authentication timeout on the system bus from 5 seconds back to 30
1205 seconds, since this has been reported to cause boot regressions for
1206 some users, mostly with parallel boot (systemd) on slower hardware.
1208 On fast systems where local users are considered particularly hostile,
1209 administrators can return to the 5 second timeout (or any other value
1210 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
1213 <limit name="auth_timeout">5000</limit>
1216 (fd.o #86431, Simon McVittie)
1218 • Add a message in syslog/the Journal when the auth_timeout is exceeded
1219 (fd.o #86431, Simon McVittie)
1221 • Send back an AccessDenied error if the addressed recipient is not allowed
1222 to receive a message (and in builds with assertions enabled, don't
1223 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
1225 D-Bus 1.9.2 (2014-11-10)
1228 The “structurally unsound flapjack” release.
1232 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
1233 so that CVE-2014-3636 part A cannot exhaust the system bus'
1234 file descriptors, completing the incomplete fix in 1.8.8.
1235 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
1239 • D-Bus Specification version 0.25
1240 · new value 'const' for EmitsChangedSignal annotation

1242 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
1243 (fd.o #83449; Lennart Poettering, Simon McVittie)
1244 · annotate table of types with reserved/basic/container, and for
1245 basic types, fixed/string-like
1246 · clarify arbitrary limits by quoting them in mebibytes
1248 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
1249 (fd.o #83449, Simon McVittie)
1251 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
1252 useful for debugging and performance testing:
1253 · dbus-test-tool spam: send repeated messages
1254 · dbus-test-tool echo: send an empty reply for all method calls
1255 · dbus-test-tool black-hole: do not reply to method calls
1256 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
1258 • Add support for process ID in credentials-passing on NetBSD
1259 (fd.o #69702, Patrick Welche)
1261 • Add an example script to find potentially undesired match rules
1262 (fd.o #84598, Alban Crequy)
1264 • Document the central assumption that makes our use of credentials-passing
1265 secure (fd.o #83499, Simon McVittie)
1267 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
1268 and add some links to GDBus and QtDBus documentation (fd.o #25140,
1273 • Use a less confusing NoReply message when disconnected with a reply pending
1274 (fd.o #76112, Simon McVittie)
1276 • Make the .pc file relocatable by letting pkg-config do all variable
1277 expansion itself (fd.o #75858, Руслан Ижбулатов)
1279 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
1280 (fd.o #85563, Patrick Welche)
1282 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
1284 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
1285 do not lose the exec() errno (fd.o #24821, Simon McVittie)
1287 • Do not fail the tests if a parent process has leaked non-close-on-exec
1288 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
1290 • Do not fail the tests on Unix platforms with incomplete
1291 credentials-passing support, but do fail if we can't pass credentials
1292 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
1293 (fd.o #69702, Simon McVittie)
1295 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
1296 when building with cmake, and expand test coverage there
1297 (fd.o #73689; Ralf Habacker, Simon McVittie)
1299 D-Bus 1.9.0 (2014-10-01)
1302 The “tiered cheeses” release.
1306 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
1307 requires either the libsystemd or libsd-daemon shared library, dropping the
1308 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
1310 Build-time configuration changes:
1312 • The Stats interface is now enabled by default, and locked-down to
1313 root-only on the system bus. Configure with --disable-stats
1314 to disable it altogether on memory- or disk-constrained systems,
1315 or see ${docdir}/examples/ to open it up to non-root users on the
1316 system bus or restrict access on the session bus.
1317 (fd.o #80759; Simon McVittie, Alban Crequy)
1319 • The CMake build system now builds the same shared library name as Autotools
1320 on at least Linux and Windows:
1321 - on Linux (and perhaps other Unix platforms), it previously built
1322 libdbus-1.so, but now builds libdbus-1.so.3.* with development
1323 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
1324 - on Windows, it previously built either libdbus-1.dll (release) or
1325 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
1326 libdbus-1.dll for compatibility with older applications.

1331 • D-Bus Specification version 0.24
1332 · document how to quote match rules (fd.o #24307, Simon McVittie)
1333 · explicitly say that most message types never expect a reply
1334 regardles of whether they have NO_REPLY_EXPECTED
1335 (fd.o #75749, Simon McVittie)
1337 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
1338 initial latency (fd.o #75544, Matt Hoosier)
1340 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
1341 (fd.o #69702, Patrick Welche)
1343 • in dbus-monitor, print more information about file descriptors
1344 (fd.o #80603, Alban Crequy)
1346 • do not install system bus configuration if built for Windows
1347 (fd.o #83583; Ralf Habacker, Simon McVittie)
1349 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
1351 • Add a regression test for file descriptor passing (fd.o #83622,
1356 • fix an incorrect error message if a Unix socket path is too long

1359 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
1360 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
1362 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
1363 in ps(1) (fd.o #69716, Chengwei Yang)
1365 • avoid calling poll() with timeout < -1, which is considered invalid
1366 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
1368 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
1369 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
1370 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
1372 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
1374 • Documentation improvements
1375 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
1377 • in dbus-monitor, do not leak file descriptors that we have monitored
1378 (fd.o #80603, Alban Crequy)
1380 • Set the close-on-exec flag for the inotify file descriptor, even
1381 if built with CMake or older libc (fd.o #73689, Simon McVittie)
1383 • Remove some LGPL code from the Windows dbus-daemon
1384 (fd.o #57272, Ralf Habacker)
1386 D-Bus 1.8.8 (2014-09-16)
1389 The "smashy smashy egg man" release.
1393 • Do not accept an extra fd in the padding of a cmsg message, which
1394 could lead to a 4-byte heap buffer overrun.
1395 (CVE-2014-3635, fd.o #83622; Simon McVittie)
1397 • Reduce default for maximum Unix file descriptors passed per message
1398 from 1024 to 16, preventing a uid with the default maximum number of
1399 connections from exhausting the system bus' file descriptors under
1400 Linux's default rlimit. Distributors or system administrators with a
1401 more restrictive fd limit may wish to reduce these limits further.
1403 Additionally, on Linux this prevents a second denial of service
1404 in which the dbus-daemon can be made to exceed the maximum number
1405 of fds per sendmsg() and disconnect the process that would have
1407 (CVE-2014-3636, fd.o #82820; Alban Crequy)
1409 • Disconnect connections that still have a fd pending unmarshalling after
1410 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
1411 removing the possibility of creating an abusive connection that cannot be
1412 disconnected by setting up a circular reference to a connection's
1414 (CVE-2014-3637, fd.o #80559; Alban Crequy)
1416 • Reduce default for maximum pending replies per connection from 8192 to 128,
1417 mitigating an algorithmic complexity denial-of-service attack
1418 (CVE-2014-3638, fd.o #81053; Alban Crequy)
1420 • Reduce default for authentication timeout on the system bus from
1421 30 seconds to 5 seconds, avoiding denial of service by using up
1422 all unauthenticated connection slots; and when all unauthenticated
1423 connection slots are used up, make new connection attempts block
1424 instead of disconnecting them.
1425 (CVE-2014-3639, fd.o #80919; Alban Crequy)
1429 • Check for libsystemd from systemd >= 209, falling back to
1430 the older separate libraries if not found (Umut Tezduyar Lindskog,
1433 • On Linux, use prctl() to disable core dumps from a test executable
1434 that deliberately raises SIGSEGV to test dbus-daemon's handling
1435 of that condition (fd.o #83772, Simon McVittie)
1437 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
1440 • Improve documentation for running tests on Windows (fd.o #41252,
1443 D-Bus 1.8.6 (2014-06-02)
1448 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
1449 the message. This prevents an attack in which a malicious client can
1450 make dbus-daemon disconnect a system service, which is a local
1452 (fd.o #80163, CVE-2014-3532; Alban Crequy)
1454 • Track remaining Unix file descriptors correctly when more than one
1455 message in quick succession contains fds. This prevents another attack
1456 in which a malicious client can make dbus-daemon disconnect a system

1459 Simon McVittie, Alban Crequy)
1463 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
1464 attach to a session, kill the dbus-daemon as intended
1465 (fd.o #74698, Роман Донченко)
1467 D-Bus 1.8.4 (2014-06-10)
1472 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
1473 flaw in dbus-daemon, part of the reference implementation of D-Bus.
1474 Additionally, in highly unusual environments the same flaw could lead to
1475 a side channel between processes that should not be able to communicate.
1476 (CVE-2014-3477, fd.o #78979)
1478 D-Bus 1.8.2 (2014-04-30)
1481 The “nobody wants red” release.
1485 • in the CMake build system, add some hints for Linux users cross-compiling
1486 Windows D-Bus binaries to be able to run tests under Wine
1487 (fd.o #41252, Ralf Habacker)
1489 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
1493 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
1494 to /var/lib/dbus/machine-id instead of generating an entirely new ID
1495 (fd.o #77941, Simon McVittie)
1497 • if dbus-launch receives an X error very quickly, do not kill
1498 unrelated processes (fd.o #74698, Роман Донченко)
1500 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
1501 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
1503 • cope with \r\n newlines in regression tests, since on Windows,
1504 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
1506 D-Bus 1.8.0 (2014-01-20)
1509 The “Wolverine distrusts my printer” release.
1511 This starts a new stable branch. The 1.6.x branch is now considered to be
1512 outdated, and will only receive fixes for serious bugs such as security
1513 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
1514 are unlikely to get any more releases, but if distributors still need to
1515 support them, please share security patches via upstream.
1517 Summary of changes since 1.6.x:
1519 • libdbus always behaves as if dbus_threads_init_default() had been called
1520 (thread-safety by default)
1521 • new dbus-run-session tool, replacing certain misuses of dbus-launch
1522 • dbus-monitor can talk to outdated versions of dbus-daemon again
1523 • new org.freedesktop.DBus.GetConnectionCredentials method
1524 • GetConnectionUnixProcessID also works correctly on Windows, returning
1525 the Windows process ID
1526 • GetConnectionWindowsSID returns the correct SID on Windows
1527 • expat is required, libxml2 can no longer be used as a substitute
1528 • the userDB cache is required, and cannot be disabled
1529 • a 64-bit integer type (either int, long, long long or _int64) is required
1530 • better systemd-journald integration on Linux
1531 • fixed long-standing fd and array leaks when failing to parse a message
1532 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
1533 when using certain object-path allocation patterns, notably in Avahi
1534 • better defaults for Windows support
1535 • better CMake support
1536 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
1537 • the source language for the man pages is now Docbook XML
1539 Enhancements since 1.7.10:
1541 • Enhance the CMake build system to check for GLib and compile/run
1542 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
1546 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
1549 • fix compilation of systemd journal support on older systemd versions where
1550 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
1552 • fix compilation on older MSVC versions by including stdlib.h
1553 (fd.o #73455, Ralf Habacker)
1555 • Allow <allow_anonymous/> to appear in an included configuration file
1556 (fd.o #73475, Matt Hoosier)
1558 Test behaviour changes since 1.7.10:
1560 • If the tests crash with an assertion failure, they no longer default to
1561 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
1562 environment if you want the old behaviour.
1564 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
1565 can be run with an external dbus-daemon by setting
1566 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
1567 an unusually-configured dbus-daemon are skipped.
1569 D-Bus 1.7.10 (2014-01-06)
1572 The “weighted companion cube” release.
1574 This is a release candidate for D-Bus 1.8.
1576 D-Bus Specification 0.23:
1578 • don't require messages with no INTERFACE to be dispatched
1579 (fd.o #68597, Simon McVittie)
1581 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
1584 • define "listenable" and "connectable" addresses, and discuss
1585 the difference (fd.o #61303, Simon McVittie)
1589 • support printing Unix file descriptors in dbus-send, dbus-monitor
1590 (fd.o #70592, Robert Ancell)
1592 • don't install systemd units if --disable-systemd is given
1593 (fd.o #71818, Chengwei Yang)
1597 • don't leak memory on out-of-memory while listing activatable or
1598 active services (fd.o #71526, Radoslaw Pajak)
1600 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
1602 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
1604 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
1605 and DBUS__SEND_MSG are numerically equal to their values in the
1606 reference policy (fd.o #88719, osmond sun)
1608 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
1609 (fd.o #71366, Matt Fischer)
1611 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
1612 winsock2.h (fd.o #71405, Matt Fischer)
1614 • do not return failure from _dbus_read_nonce() with no error set,
1615 preventing a potential crash (fd.o #72298, Chengwei Yang)
1617 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
1618 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
1620 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
1621 which doesn't do anything anyway on at least Linux and FreeBSD
1622 (fd.o #69492, Simon McVittie)
1624 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
1625 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
1626 for credentials more correctly (fd.o #69492, Simon McVittie)
1628 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
1629 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
1632 • refresh cached policy rules for existing connections when bus
1633 configuration changes (fd.o #39463, Chengwei Yang)
1635 D-Bus 1.7.8 (2013-11-01)
1638 The “extreme hills” release.
1642 • If systemd support is enabled, libsystemd-journal is now required.
1646 • When activating a non-systemd service under systemd, annotate its
1647 stdout/stderr with its bus name in the Journal. Known limitation:
1648 because the socket is opened before forking, the process will still be
1649 logged as if it had dbus-daemon's process ID and user ID.
1650 (fd.o #68559, Chengwei Yang)
1652 • Document more configuration elements in dbus-daemon(1)
1653 (fd.o #69125, Chengwei Yang)
1657 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
1658 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
1660 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
1661 disallowed method calls to the audit log, fixing a regression in 1.7.6
1662 (fd.o #49062, Colin Walters)
1664 • path_namespace='/' in match rules incorrectly matched nothing; it
1665 now matches everything. (fd.o #70799, Simon McVittie)
1667 D-Bus 1.7.6 (2013-10-09)
1670 The “CSI Shrewsbury” release.
1672 Build-time configuration changes:
1674 • Directory change notification via dnotify on Linux is no longer
1675 supported; it hadn't compiled successfully since 2010 in any case.
1676 If you don't have inotify (Linux) or kqueue (*BSD), you will need
1677 to send SIGHUP to the dbus-daemon when its configuration changes.
1678 (fd.o #33001, Chengwei Yang)
1680 • Compiling with --disable-userdb-cache is no longer supported;
1681 it didn't work since at least 2008, and would lead to an extremely
1682 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
1685 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
1686 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
1687 with the Autotools build system. (fd.o #66142, Chengwei Yang)
1689 • --with-valgrind=auto enables Valgrind instrumentation if and only if
1690 valgrind headers are available. The default is still --with-valgrind=no.
1691 (fd.o #56925, Simon McVittie)
1695 • Platforms with no 64-bit integer type are no longer supported.
1696 (fd.o #65429, Simon McVittie)
1698 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
1700 • Full test coverage no longer requires dbus-glib, although the tests do not
1701 exercise the shared library (only a static copy) if dbus-glib is missing.
1702 (fd.o #68852, Simon McVittie)
1706 • D-Bus Specification 0.22
1707 · Document GetAdtAuditSessionData() and
1708 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
1709 · Fix example .service file (fd.o #66481, Chengwei Yang)
1710 · Don't claim D-Bus is "low-latency" (lower than what?), just
1711 give factual statements about it supporting async use
1712 (fd.o #65141, Justin Lee)
1713 · Document the contents of .service files, and the fact that
1714 system services' filenames are constrained
1715 (fd.o #66608; Simon McVittie, Chengwei Yang)
1717 • Be thread-safe by default on all platforms, even if
1718 dbus_threads_init_default() has not been called. For compatibility with
1719 older libdbus, library users should continue to call
1720 dbus_threads_init_default(): it is harmless to do so.
1721 (fd.o #54972, Simon McVittie)
1723 • Add GetConnectionCredentials() method (fd.o #54445, Simon)

1840 The “but is your thread-safety thread-safe?” release.
1844 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
1845 of service for system services. Vulnerability reported by Alexandru Cornea.
1850 • The Windows version of libdbus now contains a C++ source file, used
1851 to provide global initialization when the library is loaded.
1852 gcc (mingw*) users should ensure that g++ is also installed.
1854 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
1855 and was never the recommended option) has been removed. Expat is now a
1860 • It should now be safe to call dbus_threads_init_default() from any thread,
1861 at any time. Authors of loadable modules and plugins that use libdbus
1862 should consider doing so during initialization.
1863 (fd.o #54972, Simon McVittie)
1865 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
1869 · dbus-run-session: experimental new tool to start a temporary D-Bus
1870 session, e.g. for regression tests or a text console, replacing
1871 certain uses of dbus-launch which weren't really correct

1948 or the upcoming GNOME 3.8 release.
1950 Build-time configuration changes:
1952 • The --with-dbus-session-bus-default-address configure option is no longer
1953 supported. Use the new --with-dbus-session-bus-connect-address and
1954 --with-dbus-session-bus-listen-address options instead. On Windows, you
1955 usually want them to have the same argument; on Unix, the defaults are
1958 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
1959 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
1960 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
1962 • cmake/cross-compile.sh has been removed. Instead, please use a
1963 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at

2015 · The default session bus listening and connecting address is now
2016 "autolaunch:", which makes D-Bus on Windows interoperate with itself
2017 and GDBus "out of the box". Use the configure options and cmake variables
2018 described above if you require a different autolaunch scope.
2019 (fd.o #38201, Simon McVittie)
2020 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)

2179 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
2180 and SUSv2) is now required.
2182 • D-Bus Specification 0.19:
2183 · Formally define unique connection names and well-known bus names,
2184 and document best practices for interface, bus, member and error names,
2185 and object paths (fd.o #37095, Simon McVittie)

2222 • Add dbus-daemon --nopidfile option, overriding the configuration, for
2223 setups where the default configuration must include <pidfile/> to avoid
2224 breaking traditional init, but the pid file is in fact unnecessary; use
2225 it under systemd to improve startup time a bit (fd.o #45520,

2246 been broken since 2006, with an ordinary pthreads recursive mutex
2247 (fd.o #43744; Sigmund Augdal, Simon McVittie)
2248 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
2249 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
2250 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
2251 · When running under systemd, use it instead of ConsoleKit to check
2252 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
2253 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
2254 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
2255 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
2256 (fd.o #41218, Simon McVittie)
2257 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
2258 helper doesn't obey environment variables to avoid privilege escalation
2259 attacks, so make the system bus follow the same rules
2260 (fd.o #21620, Simon McVittie)
2263 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
2264 Jesper Dam, Ralf Habacker)

2268 D-Bus 1.5.8 (2011-09-21)
2271 The "cross-metering" release.
2273 In addition to dead code removal and refactoring, this release contains all
2274 of the bugfixes from 1.4.16.
2276 • Clean up dead code, and make more warnings fatal in development builds
2277 (fd.o #39231, fd.o #41012; Simon McVittie)
2279 • If full test coverage is requested via --enable-tests, strictly require
2280 Python, pygobject and dbus-python, which are required by some tests; if not,
2281 and Python is missing, skip those tests rather than failing
2282 (fd.o #37847, Simon McVittie)
2284 • When using cmake, provide the same version-info API in the installed headers
2285 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
2287 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
2289 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
2291 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
2294 • Fix duplicates in authors list (Ralf Habacker)
2296 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
2297 (fd.o #39879, Chris Mayo)
2299 • Fix a small memory leak, and a failure to report errors, when updating
2300 a service file entry for activation (fd.o #39230, Simon McVittie)
2303 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
2304 Brian Cameron, Simon McVittie)
2305 · On systems that use libcap-ng but not systemd, drop supplemental groups
2306 when switching to the daemon user (Red Hat #726953, Steve Grubb)
2307 · Make the cmake build work again on GNU platforms (fd.o #29228,
2309 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
2310 like Solaris (fd.o #40313, Dagobert Michelsen)
2311 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
2312 (fd.o #40235, Simon McVittie)
2313 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
2314 (fd.o #39987, Simon McVittie)
2315 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
2316 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
2319 · Fix compilation on MSVC, which doesn't understand "inline" with its
2320 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
2321 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
2322 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
2324 D-Bus 1.5.6 (2011-07-29)
2327 The "weird, gravy-like aftertaste" release.
2329 In addition to new features and refactoring, this release contains all of the
2330 bugfixes from 1.4.14.
2332 Potentially incompatible (Bustle and similar debugging tools will need
2333 changes to work as intended):
2335 • Do not allow match rules to "eavesdrop" (receive messages intended for a
2336 different recipient) by mistake: eavesdroppers must now opt-in to this
2337 behaviour by putting "eavesdrop='true'" in the match rule, which will
2338 not have any practical effect on buses where eavesdropping is not allowed
2339 (fd.o #37890, Cosimo Alfarano)
2343 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
2344 Cosimo Alfarano, Simon McVittie)
2345 · add the "eavesdrop" keyword to match rules
2346 · define eavesdropping, unicast messages and broadcast messages
2347 · stop claiming that match rules are needed to match unicast messages to you
2348 · promote the type system to be a top-level section
2350 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
2351 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
2352 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
2354 • Consistently use atomic operations on everything that is ever manipulated
2355 via atomic ops, as was done for changes to DBusConnection's refcount in
2356 1.4.12 (fd.o #38005, Simon McVittie)
2358 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
2361 • Make "make check" in a clean tree work, by not running tests until
2362 test data has been set up (fd.o #34405, Simon McVittie)
2364 • The dbus-daemon no longer busy-loops if it has a very large number of file
2365 descriptors (fd.o #23194, Simon McVittie)
2367 • Refactor message flow through dispatching to avoid locking violations if
2368 the bus daemon's message limit is hit; remove the per-connection link cache,
2369 which was meant to improve performance, but now reduces it (fd.o #34393,
2372 • Some cmake fixes (Ralf Habacker)
2374 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
2375 Simon McVittie, Lennart Poettering)
2377 • Stop storing two extra byte order indicators in each D-Bus message
2378 (fd.o #38287, Simon McVittie)
2380 • Add an optional Stats interface which can be used to get statistics from
2381 a running dbus-daemon if enabled at configure time with --enable-stats
2382 (fd.o #34040, Simon McVittie)
2384 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
2386 • Documentation (fd.o #36156, Simon McVittie):
2387 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
2388 · install more documentation automatically, including man2html output
2389 · put dbus.devhelp in the right place (it must go in ${htmldir})
2392 · look for system services in /lib/dbus-1/system-services in addition to all
2393 the other well-known locations; note that this should always be /lib,
2394 even on platforms where shared libraries on the root FS would go in /lib64,
2395 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
2396 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
2398 • Windows-specific (Ralf Habacker):
2399 · fix use of a mutex for autolaunch server detection
2400 · don't crash on malloc failure in _dbus_printf_string_upper_bound
2402 D-Bus 1.5.4 (2011-06-10)
2405 Security (local denial of service):
2407 • Byte-swap foreign-endian messages correctly, preventing a long-standing
2408 local DoS if foreign-endian messages are relayed through the dbus-daemon
2409 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
2410 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
2414 • The constant to use for an infinite timeout now has a name,
2415 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
2416 which can be used for source compatibility with older versions of libdbus.
2418 • If GLib and DBus-GLib are already installed, more tests will be built,
2419 providing better coverage. The new tests can also be installed via
2420 ./configure --enable-installed-tests
2421 for system integration testing, if required. (fd.o #34570, Simon McVittie)
2425 • Consistently use atomic operations for the DBusConnection's refcount,
2426 fixing potential threading problems (fd.o #38005, Simon McVittie)
2428 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
2429 small (300KiB on x86-64) and it frequently doesn't work in unusual
2430 toolchains. To optimize for minimum installed size, you should benchmark
2431 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
2432 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
2434 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
2435 (fd.o #35880, Timothy Redaelli)
2437 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
2438 when not using a DESTDIR (fd.o #37870, Simon McVittie)
2440 • Windows-specific changes:
2441 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
2443 D-Bus 1.5.2 (2011-06-01)
2446 The "Boar Hunter" release.
2448 Notes for distributors:
2450 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
2451 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
2452 toolchain supports it reliably, via something like:
2454 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
2456 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
2460 • D-Bus Specification v0.17
2461 · Reserve the extra characters used in signatures by GVariant
2462 (fd.o #34529, Simon McVittie)
2463 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
2464 • Don't force -fPIE: distributions and libtool know better than we do whether
2465 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
2466 • Allow --disable-gc-sections, in case your toolchain offers the
2467 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
2468 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
2469 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
2470 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
2471 • Ensure that maintainers upload documentation with the right permissions
2472 (fd.o #36130, Simon McVittie)
2473 • Don't force users of libdbus to be linked against -lpthread, -lrt
2474 (fd.o #32827, Simon McVittie)
2475 • Log system-bus activation information to syslog (fd.o #35705,
2477 • Log messages dropped due to quotas to syslog (fd.o #35358,
2479 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
2480 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
2481 (fd.o #35228, Lennart Poettering)
2482 • In the regression tests, don't report fds as "leaked" if they were open
2483 on startup (fd.o #35173, Simon McVittie)
2484 • Make dbus-monitor bail out if asked to monitor more than one bus,
2485 rather than silently using the last one (fd.o #26548, Will Thompson)
2486 • Clarify documentation (fd.o #35182, Simon McVittie)
2487 • Clean up minor dead code and some incorrect error handling
2488 (fd.o #33128, fd.o #29881; Simon McVittie)
2489 • Check that compiler options are supported before using them (fd.o #19681,
2492 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
2494 D-Bus 1.5.0 (2011-04-11)
2497 The "you never know when you need to tow something from your giant
2498 flying shark" release.
2500 • D-Bus Specification v0.16
2501 · Add support for path_namespace and arg0namespace in match rules
2502 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
2503 · Make argNpath support object paths, not just object-path-like strings,
2504 and document it better (fd.o #31818, Will Thompson)
2505 • Let the bus daemon implement more than one interface (fd.o #33757,
2507 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
2509 • Require user intervention to compile with missing 64-bit support
2510 (fd.o #35114, Simon McVittie)
2511 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
2512 • Raise UnknownObject instead of UnknownMethod for calls to methods on
2513 paths that are not part of the object tree, and UnknownInterface for calls
2514 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
2516 D-Bus 1.4.8 (2011-04-08)
2519 The "It's like the beginning of a lobster" release.
2521 • Rename configure.in to configure.ac, and update it to modern conventions
2522 (fd.o #32245; Javier Jardón, Simon McVittie)
2523 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
2525 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
2526 --disable-x11-autolaunch configure option to prevent it altogether
2527 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
2528 • Install the documentation, and an index for Devhelp (fd.o #13495,
2529 Debian #454142; Simon McVittie, Matthias Clasen)
2530 • If checks are not disabled, check validity of string-like types and
2531 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
2532 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
2533 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
2534 • Break up a huge conditional in config-parser so gcov can produce coverage
2535 data (fd.o #10887, Simon McVittie)
2536 • List which parts of the Desktop Entry specification are applicable to
2537 .service files (fd.o #19159, Sven Herzberg)
2538 • Don't suppress service activation if two services have the same Exec=
2539 (fd.o #35750, Colin Walters)

2549 The "1, 2, miss a few, 99, 100" release.
2551 • Remove unfinished changes intended to support GTest-based tests,
2552 which were mistakenly included in 1.4.4
2554 D-Bus 1.4.4 (2010-02-17)
2557 • Switch back to using even micro versions for stable releases; 1.4.1
2558 should have been called 1.4.2, so skip that version number
2559 • Don't leave bad file descriptors being watched when spawning processes,
2560 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
2561 also LP#656134, LP#680444, LP#713157)
2562 • Check for MSG_NOSIGNAL correctly
2563 • Fix failure to detect abstract socket support (fd.o #29895)
2564 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
2565 (fd.o #32262, NB#180486)

2596 crash the bus. The existing restriction to 64-levels of nesting previously
2597 only applied to the static type signature; now it also applies to dynamic
2598 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
2600 • OS X portability fixes, including launchd support.
