1 D-Bus 1.9.18 (UNRELEASED)
6 D-Bus 1.9.16 (2015-05-14)
9 The “titanium barns” release.
13 • Automake 1.13 is now required when compiling from git or modifying
18 • On Unix platforms, change the default configuration for the session bus
19 to only allow EXTERNAL authentication (secure kernel-mediated
20 credentials-passing), as was already done for the system bus.
22 This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly
23 unpredictable pseudo-random numbers.
25 If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport,
26 in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using
27 NFS or similar, you will need to reconfigure the session bus to accept
28 DBUS_COOKIE_SHA1 by commenting out the <auth> element. This configuration
31 (fd.o #90414, Simon McVittie)
33 • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp:
34 transport, UUIDs or any other reason, fail if we cannot obtain entropy
35 (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition
36 occurs, instead of silently falling back to low-entropy pseudorandom
37 numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker)
41 • Add dbus_message_iter_get_element_count()
42 (fd.o #30350; Christian Dywan, Simon McVittie)
44 • Introduce new internal DBusSocket and DBusPollable types so we can
45 stop treating the Windows SOCKET type as if it was int. DBusSocket
46 is specifically a socket, cross-platform. DBusPollable is whatever
47 _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows.
48 (fd.o #89444; Ralf Habacker, Simon McVittie)
50 • All regression tests now output TAP <https://testanything.org/>
51 (fd.o #89846, Simon McVittie)
53 • Internal APIs consistently use signed values for timestamps
54 (fd.o #18494, Peter McCurdy)
56 • Improve diagnostics when UpdateActivationEnvironment calls are rejected
57 (fd.o #88812, Simon McVittie)
59 • Clean up a lot of compiler warnings
60 (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie)
64 • Add locking to DBusCounter's reference count and notify function
65 (fd.o #89297, Adrian Szyndela)
67 • Ensure that DBusTransport's reference count is protected by the
68 corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela)
70 • Correctly release DBusServer mutex before early-return if we run out
71 of memory while copying authentication mechanisms (fd.o #90021,
74 • Make dbus-test-tool and dbus-update-activation-environment portable
75 to Windows (fd.o #90089, Ralf Habacker)
77 • Correctly initialize all fields of DBusTypeReader (fd.o #90021;
78 Ralf Habacker, Simon McVittie)
80 • Fix some missing \n in verbose (debug log) messages (fd.o #90004,
83 • Clean up some memory and fd leaks in test code and tools
84 (fd.o #90021, Ralf Habacker)
86 • Fix a NULL dereference if the dbus-daemon cannot read a configuration
87 directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker)
89 • CMake generates a versioned shared library even if the revision is 0,
90 as it usually is on the development branch. (fd.o #89450, Ralf Habacker)
92 D-Bus 1.9.14 (2015-03-02)
95 The “don't stand in the poison cloud” release.
99 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
100 were previously linked to a static version of libdbus.
102 • The tests no longer require dbus-glib in order to exercise the libdbus
103 shared library; they are always linked to libdbus now.
105 Build-time configuration:
107 • The new --enable-user-session option, off by default, can be enabled
108 by OS integrators intending to use systemd to provide a session bus
109 per user (in effect, treating all concurrent graphical and non-graphical
110 login sessions as one large session)
114 • All executables are now linked dynamically to libdbus.
115 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
117 • On platforms that support them (GNU libc and possibly others),
118 libdbus now has versioned symbols for its public API.
119 All public symbols (visible in the header files) are currently
120 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
121 dbus_internal have a version that changes with each release, and
122 must not be used by applications. (also fd.o #83115)
124 • New listenable address mode "unix:runtime=yes" which listens on
125 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
126 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
128 • Add optional systemd units for a per-user bus listening on
129 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
131 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
132 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
135 • New dbus-update-activation-environment tool uploads environment
136 variables to "dbus-daemon --session" and optionally "systemd --user",
137 primarily as a way to keep the per-user bus compatible with
138 distributions' existing X11 login scripts (also fd.o #61301)
140 • <includedir/> elements in dbus-daemon configuration are now silently
141 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
143 • Add microsecond-resolution timestamps to the default output of
144 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
148 • Fix a race condition in the 'monitor' test introduced in 1.9.10
149 (fd.o #89222, Simon McVittie)
151 D-Bus 1.9.12 (2015-02-19)
154 The “monster lasagna” release.
158 • Ducktype and yelp-tools are now required to build complete documentation
159 (they are optional for normal builds).
163 • D-Bus Specification version 0.26
164 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
165 · document the BecomeMonitor method
167 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
168 (fd.o #89041; Tyler Hicks, Simon McVittie)
170 • On Linux, add support for AppArmor mediation of message sending and
171 receiving and name ownership (paralleling existing SELinux mediation
172 support), and eavesdropping (a new check, currently AppArmor-specific)
173 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
175 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
176 that have printable ASCII contents; we previously only did this for
177 unterminated bytestrings (fd.o #89109, Simon McVittie)
179 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
181 • On Windows, add WindowsSID to GetConnectionCredentials
182 (fd.o #54445, Ralf Habacker)
184 • Improve clarity of dbus-monitor --profile output and add more columns
185 (fd.o #89165, Ralf Habacker)
187 • Add a man page for dbus-test-tool, and build it under CMake as well
188 as Autotools (fd.o#89086, Simon McVittie)
190 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
191 to control it at runtime, overriding the DBUS_VERBOSE environment variable
192 (fd.o #88896, Ralf Habacker)
196 • Reduce the number of file descriptors used in the fd-passing test,
197 avoiding failure under the default Linux fd limit, and automatically
198 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
200 D-Bus 1.9.10 (2015-02-09)
203 The “sad cyborgs” release.
205 Security fixes merged from 1.8.16:
207 • Do not allow non-uid-0 processes to send forged ActivationFailure
208 messages. On Linux systems with systemd activation, this would
209 allow a local denial of service: unprivileged processes could
210 flood the bus with these forged messages, winning the race with
211 the actual service activation and causing an error reply
212 to be sent back when service auto-activation was requested.
213 This does not prevent the real service from being started,
214 so the attack only works while the real service is not running.
215 (CVE-2015-0245, fd.o #88811; Simon McVittie)
219 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
220 similar tools receive messages without altering the security properties
221 of the system bus, by calling the new BecomeMonitor method on a
222 private connection. This bypasses the normal <allow> and <deny> rules
223 entirely, so to preserve normal message-privacy assumptions, only root
224 is allowed to do this on the system bus. Restricted environments,
225 such as Linux with LSMs, should lock down access to the Monitoring
226 interface. (fd.o #46787, Simon McVittie)
228 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
229 dbus-daemon supports it and access permissions allow it.
230 It still supports the previous approach ("eavesdropping" match rules)
231 for compatibility with older bus daemons. (fd.o #46787, Simon)
233 • dbus-monitor can now log the message stream as binary data for later
234 analysis, with either no extra framing beyond the normal D-Bus headers,
235 or libpcap-compatible framing treating each D-Bus message
236 as a captured packet. (fd.o #46787, Simon)
240 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
242 • On Unix, forcibly terminate regression tests after 60 seconds to
243 prevent them from blocking continuous integration frameworks
246 D-Bus 1.9.8 (2015-02-03)
249 The “all the types of precipitation” release.
253 • full test coverage now requires GLib 2.36
254 • full test coverage now requires PyGI (PyGObject 3,
255 "import gi.repository.GObject") instead of the
256 obsolete PyGObject 2 ("import gobject")
260 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
262 • better regression test coverage, including systemd activation
263 (fd.o #57952, #88810; Simon McVittie)
267 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
268 turned off (fd.o #88808, Simon McVittie)
270 • TCP sockets on Windows no longer fail to listen approximately 1 time
271 in 256, caused by a logic error that should have always made it fail but
272 was mitigated by incorrect endianness for the port number
273 (fd.o #87999, Ralf Habacker)
275 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
277 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
278 previous 64, completing a previous fix which only worked under
279 Autotools (fd.o #71297, Ralf Habacker)
281 • on Windows, if the IP family is unspecified only use IPv4,
282 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
284 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
286 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
288 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
291 D-Bus 1.9.6 (2015-01-05)
294 The “I do have a bread knife” release.
298 • Do not allow calls to UpdateActivationEnvironment from uids other than
299 the uid of the dbus-daemon. If a system service installs unsafe
300 security policy rules that allow arbitrary method calls
301 (such as CVE-2014-8148) then this prevents memory consumption and
302 possible privilege escalation via UpdateActivationEnvironment.
304 We believe that in practice, privilege escalation here is avoided
305 by dbus-daemon-launch-helper sanitizing its environment; but
306 it seems better to be safe.
308 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
309 on object paths other than /org/freedesktop/DBus. Some system services
310 install unsafe security policy rules that allow arbitrary method calls
311 to any destination, method and interface with a specified object path;
312 while less bad than allowing arbitrary method calls, these security
313 policies are still harmful, since dbus-daemon normally offers the
314 same API on all object paths and other system services might behave
319 • Add missing initialization so GetExtendedTcpTable doesn't crash on
320 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
322 D-Bus 1.9.4 (2014-11-24)
325 The “extra-sturdy caramel” release.
329 • Partially revert the CVE-2014-3639 patch by increasing the default
330 authentication timeout on the system bus from 5 seconds back to 30
331 seconds, since this has been reported to cause boot regressions for
332 some users, mostly with parallel boot (systemd) on slower hardware.
334 On fast systems where local users are considered particularly hostile,
335 administrators can return to the 5 second timeout (or any other value
336 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
339 <limit name="auth_timeout">5000</limit>
342 (fd.o #86431, Simon McVittie)
344 • Add a message in syslog/the Journal when the auth_timeout is exceeded
345 (fd.o #86431, Simon McVittie)
347 • Send back an AccessDenied error if the addressed recipient is not allowed
348 to receive a message (and in builds with assertions enabled, don't
349 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
351 D-Bus 1.9.2 (2014-11-10)
354 The “structurally unsound flapjack” release.
358 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
359 so that CVE-2014-3636 part A cannot exhaust the system bus'
360 file descriptors, completing the incomplete fix in 1.8.8.
361 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
365 • D-Bus Specification version 0.25
366 · new value 'const' for EmitsChangedSignal annotation
367 (fd.o #72958, Lennart Poettering)
368 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
369 (fd.o #83449; Lennart Poettering, Simon McVittie)
370 · annotate table of types with reserved/basic/container, and for
371 basic types, fixed/string-like
372 · clarify arbitrary limits by quoting them in mebibytes
374 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
375 (fd.o #83449, Simon McVittie)
377 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
378 useful for debugging and performance testing:
379 · dbus-test-tool spam: send repeated messages
380 · dbus-test-tool echo: send an empty reply for all method calls
381 · dbus-test-tool black-hole: do not reply to method calls
382 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
384 • Add support for process ID in credentials-passing on NetBSD
385 (fd.o #69702, Patrick Welche)
387 • Add an example script to find potentially undesired match rules
388 (fd.o #84598, Alban Crequy)
390 • Document the central assumption that makes our use of credentials-passing
391 secure (fd.o #83499, Simon McVittie)
393 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
394 and add some links to GDBus and QtDBus documentation (fd.o #25140,
399 • Use a less confusing NoReply message when disconnected with a reply pending
400 (fd.o #76112, Simon McVittie)
402 • Make the .pc file relocatable by letting pkg-config do all variable
403 expansion itself (fd.o #75858, Руслан Ижбулатов)
405 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
406 (fd.o #85563, Patrick Welche)
408 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
410 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
411 do not lose the exec() errno (fd.o #24821, Simon McVittie)
413 • Do not fail the tests if a parent process has leaked non-close-on-exec
414 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
416 • Do not fail the tests on Unix platforms with incomplete
417 credentials-passing support, but do fail if we can't pass credentials
418 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
419 (fd.o #69702, Simon McVittie)
421 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
422 when building with cmake, and expand test coverage there
423 (fd.o #73689; Ralf Habacker, Simon McVittie)
425 D-Bus 1.9.0 (2014-10-01)
428 The “tiered cheeses” release.
432 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
433 requires either the libsystemd or libsd-daemon shared library, dropping the
434 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
436 Build-time configuration changes:
438 • The Stats interface is now enabled by default, and locked-down to
439 root-only on the system bus. Configure with --disable-stats
440 to disable it altogether on memory- or disk-constrained systems,
441 or see ${docdir}/examples/ to open it up to non-root users on the
442 system bus or restrict access on the session bus.
443 (fd.o #80759; Simon McVittie, Alban Crequy)
445 • The CMake build system now builds the same shared library name as Autotools
446 on at least Linux and Windows:
447 - on Linux (and perhaps other Unix platforms), it previously built
448 libdbus-1.so, but now builds libdbus-1.so.3.* with development
449 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
450 - on Windows, it previously built either libdbus-1.dll (release) or
451 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
452 libdbus-1.dll for compatibility with older applications.
453 (fd.o #74117, Ralf Habacker)
457 • D-Bus Specification version 0.24
458 · document how to quote match rules (fd.o #24307, Simon McVittie)
459 · explicitly say that most message types never expect a reply
460 regardles of whether they have NO_REPLY_EXPECTED
461 (fd.o #75749, Simon McVittie)
463 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
464 initial latency (fd.o #75544, Matt Hoosier)
466 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
467 (fd.o #69702, Patrick Welche)
469 • in dbus-monitor, print more information about file descriptors
470 (fd.o #80603, Alban Crequy)
472 • do not install system bus configuration if built for Windows
473 (fd.o #83583; Ralf Habacker, Simon McVittie)
475 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
477 • Add a regression test for file descriptor passing (fd.o #83622,
482 • fix an incorrect error message if a Unix socket path is too long
483 (fd.o #73887, Antoine Jacoutot)
485 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
486 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
488 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
489 in ps(1) (fd.o #69716, Chengwei Yang)
491 • avoid calling poll() with timeout < -1, which is considered invalid
492 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
494 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
495 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
496 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
498 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
500 • Documentation improvements
501 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
503 • in dbus-monitor, do not leak file descriptors that we have monitored
504 (fd.o #80603, Alban Crequy)
506 • Set the close-on-exec flag for the inotify file descriptor, even
507 if built with CMake or older libc (fd.o #73689, Simon McVittie)
509 • Remove some LGPL code from the Windows dbus-daemon
510 (fd.o #57272, Ralf Habacker)
512 D-Bus 1.8.8 (2014-09-16)
515 The "smashy smashy egg man" release.
519 • Do not accept an extra fd in the padding of a cmsg message, which
520 could lead to a 4-byte heap buffer overrun.
521 (CVE-2014-3635, fd.o #83622; Simon McVittie)
523 • Reduce default for maximum Unix file descriptors passed per message
524 from 1024 to 16, preventing a uid with the default maximum number of
525 connections from exhausting the system bus' file descriptors under
526 Linux's default rlimit. Distributors or system administrators with a
527 more restrictive fd limit may wish to reduce these limits further.
529 Additionally, on Linux this prevents a second denial of service
530 in which the dbus-daemon can be made to exceed the maximum number
531 of fds per sendmsg() and disconnect the process that would have
533 (CVE-2014-3636, fd.o #82820; Alban Crequy)
535 • Disconnect connections that still have a fd pending unmarshalling after
536 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
537 removing the possibility of creating an abusive connection that cannot be
538 disconnected by setting up a circular reference to a connection's
540 (CVE-2014-3637, fd.o #80559; Alban Crequy)
542 • Reduce default for maximum pending replies per connection from 8192 to 128,
543 mitigating an algorithmic complexity denial-of-service attack
544 (CVE-2014-3638, fd.o #81053; Alban Crequy)
546 • Reduce default for authentication timeout on the system bus from
547 30 seconds to 5 seconds, avoiding denial of service by using up
548 all unauthenticated connection slots; and when all unauthenticated
549 connection slots are used up, make new connection attempts block
550 instead of disconnecting them.
551 (CVE-2014-3639, fd.o #80919; Alban Crequy)
555 • Check for libsystemd from systemd >= 209, falling back to
556 the older separate libraries if not found (Umut Tezduyar Lindskog,
559 • On Linux, use prctl() to disable core dumps from a test executable
560 that deliberately raises SIGSEGV to test dbus-daemon's handling
561 of that condition (fd.o #83772, Simon McVittie)
563 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
566 • Improve documentation for running tests on Windows (fd.o #41252,
569 D-Bus 1.8.6 (2014-06-02)
574 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
575 the message. This prevents an attack in which a malicious client can
576 make dbus-daemon disconnect a system service, which is a local
578 (fd.o #80163, CVE-2014-3532; Alban Crequy)
580 • Track remaining Unix file descriptors correctly when more than one
581 message in quick succession contains fds. This prevents another attack
582 in which a malicious client can make dbus-daemon disconnect a system
584 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
585 Simon McVittie, Alban Crequy)
589 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
590 attach to a session, kill the dbus-daemon as intended
591 (fd.o #74698, Роман Донченко)
593 D-Bus 1.8.4 (2014-06-10)
598 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
599 flaw in dbus-daemon, part of the reference implementation of D-Bus.
600 Additionally, in highly unusual environments the same flaw could lead to
601 a side channel between processes that should not be able to communicate.
602 (CVE-2014-3477, fd.o #78979)
604 D-Bus 1.8.2 (2014-04-30)
607 The “nobody wants red” release.
611 • in the CMake build system, add some hints for Linux users cross-compiling
612 Windows D-Bus binaries to be able to run tests under Wine

615 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
619 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
620 to /var/lib/dbus/machine-id instead of generating an entirely new ID
621 (fd.o #77941, Simon McVittie)
623 • if dbus-launch receives an X error very quickly, do not kill
624 unrelated processes (fd.o #74698, Роман Донченко)
626 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
627 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
629 • cope with \r\n newlines in regression tests, since on Windows,
630 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
632 D-Bus 1.8.0 (2014-01-20)
635 The “Wolverine distrusts my printer” release.
637 This starts a new stable branch. The 1.6.x branch is now considered to be
638 outdated, and will only receive fixes for serious bugs such as security
639 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
640 are unlikely to get any more releases, but if distributors still need to
641 support them, please share security patches via upstream.
643 Summary of changes since 1.6.x:
645 • libdbus always behaves as if dbus_threads_init_default() had been called
646 (thread-safety by default)
647 • new dbus-run-session tool, replacing certain misuses of dbus-launch
648 • dbus-monitor can talk to outdated versions of dbus-daemon again
649 • new org.freedesktop.DBus.GetConnectionCredentials method
650 • GetConnectionUnixProcessID also works correctly on Windows, returning
651 the Windows process ID
652 • GetConnectionWindowsSID returns the correct SID on Windows
653 • expat is required, libxml2 can no longer be used as a substitute
654 • the userDB cache is required, and cannot be disabled
655 • a 64-bit integer type (either int, long, long long or _int64) is required
656 • better systemd-journald integration on Linux
657 • fixed long-standing fd and array leaks when failing to parse a message
658 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
659 when using certain object-path allocation patterns, notably in Avahi
660 • better defaults for Windows support
661 • better CMake support
662 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
663 • the source language for the man pages is now Docbook XML
665 Enhancements since 1.7.10:
667 • Enhance the CMake build system to check for GLib and compile/run
668 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
672 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
675 • fix compilation of systemd journal support on older systemd versions where
676 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
678 • fix compilation on older MSVC versions by including stdlib.h
679 (fd.o #73455, Ralf Habacker)
681 • Allow <allow_anonymous/> to appear in an included configuration file
682 (fd.o #73475, Matt Hoosier)
684 Test behaviour changes since 1.7.10:
686 • If the tests crash with an assertion failure, they no longer default to
687 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
688 environment if you want the old behaviour.
690 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
691 can be run with an external dbus-daemon by setting
692 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
693 an unusually-configured dbus-daemon are skipped.
695 D-Bus 1.7.10 (2014-01-06)
698 The “weighted companion cube” release.
700 This is a release candidate for D-Bus 1.8.
702 D-Bus Specification 0.23:
704 • don't require messages with no INTERFACE to be dispatched
705 (fd.o #68597, Simon McVittie)
707 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
710 • define "listenable" and "connectable" addresses, and discuss
711 the difference (fd.o #61303, Simon McVittie)
715 • support printing Unix file descriptors in dbus-send, dbus-monitor
716 (fd.o #70592, Robert Ancell)
718 • don't install systemd units if --disable-systemd is given
719 (fd.o #71818, Chengwei Yang)
723 • don't leak memory on out-of-memory while listing activatable or
724 active services (fd.o #71526, Radoslaw Pajak)
726 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
728 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
730 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
731 and DBUS__SEND_MSG are numerically equal to their values in the
732 reference policy (fd.o #88719, osmond sun)
734 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
735 (fd.o #71366, Matt Fischer)
737 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
738 winsock2.h (fd.o #71405, Matt Fischer)
740 • do not return failure from _dbus_read_nonce() with no error set,
741 preventing a potential crash (fd.o #72298, Chengwei Yang)
743 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
744 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
746 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
747 which doesn't do anything anyway on at least Linux and FreeBSD
748 (fd.o #69492, Simon McVittie)
750 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
751 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
752 for credentials more correctly (fd.o #69492, Simon McVittie)
754 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
755 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
758 • refresh cached policy rules for existing connections when bus
759 configuration changes (fd.o #39463, Chengwei Yang)
761 D-Bus 1.7.8 (2013-11-01)
764 The “extreme hills” release.
768 • If systemd support is enabled, libsystemd-journal is now required.
772 • When activating a non-systemd service under systemd, annotate its
773 stdout/stderr with its bus name in the Journal. Known limitation:
774 because the socket is opened before forking, the process will still be
775 logged as if it had dbus-daemon's process ID and user ID.
776 (fd.o #68559, Chengwei Yang)
778 • Document more configuration elements in dbus-daemon(1)
779 (fd.o #69125, Chengwei Yang)
783 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
784 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
786 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
787 disallowed method calls to the audit log, fixing a regression in 1.7.6
788 (fd.o #49062, Colin Walters)
790 • path_namespace='/' in match rules incorrectly matched nothing; it
791 now matches everything. (fd.o #70799, Simon McVittie)
793 D-Bus 1.7.6 (2013-10-09)
796 The “CSI Shrewsbury” release.
798 Build-time configuration changes:
800 • Directory change notification via dnotify on Linux is no longer
801 supported; it hadn't compiled successfully since 2010 in any case.
802 If you don't have inotify (Linux) or kqueue (*BSD), you will need
803 to send SIGHUP to the dbus-daemon when its configuration changes.
804 (fd.o #33001, Chengwei Yang)
806 • Compiling with --disable-userdb-cache is no longer supported;
807 it didn't work since at least 2008, and would lead to an extremely
808 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
811 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
812 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
813 with the Autotools build system. (fd.o #66142, Chengwei Yang)
815 • --with-valgrind=auto enables Valgrind instrumentation if and only if
816 valgrind headers are available. The default is still --with-valgrind=no.
817 (fd.o #56925, Simon McVittie)
821 • Platforms with no 64-bit integer type are no longer supported.
822 (fd.o #65429, Simon McVittie)
824 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
826 • Full test coverage no longer requires dbus-glib, although the tests do not
827 exercise the shared library (only a static copy) if dbus-glib is missing.
828 (fd.o #68852, Simon McVittie)
832 • D-Bus Specification 0.22
833 · Document GetAdtAuditSessionData() and
834 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
835 · Fix example .service file (fd.o #66481, Chengwei Yang)
836 · Don't claim D-Bus is "low-latency" (lower than what?), just
837 give factual statements about it supporting async use
838 (fd.o #65141, Justin Lee)
839 · Document the contents of .service files, and the fact that
840 system services' filenames are constrained
841 (fd.o #66608; Simon McVittie, Chengwei Yang)
843 • Be thread-safe by default on all platforms, even if
844 dbus_threads_init_default() has not been called. For compatibility with
845 older libdbus, library users should continue to call
846 dbus_threads_init_default(): it is harmless to do so.
847 (fd.o #54972, Simon McVittie)
849 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
851 • New API: dbus_setenv(), a simple wrapper around setenv().
852 Note that this is not thread-safe. (fd.o #39196, Simon)
854 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
855 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
856 (connect to a given bus, like dbus-monitor --address=ADDRESS).
857 dbus-send --address still exists for backwards compatibility,
858 but is no longer documented. (fd.o #48816, Andrey Mazo)
861 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
866 • Avoid an infinite busy-loop if a signal interrupts waitpid()
867 (fd.o #68945, Simon McVittie)
869 • Clean up memory for parent nodes when objects are unexported
870 (fd.o #60176, Thomas Fitzsimmons)
872 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
873 documented. Previously, it assumed its second parameter was TRUE.
874 (fd.o #69165, Chengwei Yang)
876 • Escape addresses containing non-ASCII characters correctly
877 (fd.o #53499, Chengwei Yang)
879 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
881 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
882 (fd.o #65923, Chengwei Yang)
884 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
885 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
887 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
888 that was never va_start()ed (fd.o #66300, Chengwei Yang)
890 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
892 • fix a regression test on platforms with strict alignment (fd.o #67279,
895 • Avoid calling function parameters "interface" since certain Windows headers
896 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
898 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
900 • Various thread-safety improvements to static variables (fd.o #68610,
903 • Make "make -j check" work (fd.o #68852, Simon McVittie)
905 • Fix a NULL pointer dereference on an unlikely error path
906 (fd.o #69327, Sviatoslav Chagaev)
908 • Improve valgrind memory pool tracking (fd.o #69326,
911 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
914 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
915 (fd.o #66107, Chengwei Yang)
918 · If accept4() fails with EINVAL, as it can on older Linux kernels
919 with newer glibc, try accept() instead of going into a busy-loop.
920 (fd.o #69026, Chengwei Yang)
921 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
922 for instance on Hurd or older Linux with a new glibc, try without
923 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)
924 · Fix a file descriptor leak on an error code path.
925 (fd.o #69182, Sviatoslav Chagaev)
926 · dbus-run-session: clear some unwanted environment variables

929 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
930 · Use dbus-launch from the builddir for testing, not the installed copy
931 (fd.o #37849, Chengwei Yang)
932 · Fix compilation if writev() is unavailable (fd.o #69409,
934 · Remove broken support for LOCAL_CREDS credentials passing, and
935 document where each credential-passing scheme is used (fd.o #60340,
937 · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality
938 (fd.o #35881, #69787; Chengwei Yang)
939 · dbus-monitor: be portable to NetBSD (fd.o #69842, Chengwei Yang)
940 · dbus-launch: stop using non-portable asprintf (fd.o #37849, Simon)
941 · Improve error reporting from the setuid activation helper (fd.o #66728,
945 · Remove unavailable command-line options from 'dbus-daemon --help'
946 (fd.o #42441, Ralf Habacker)

948 Windows XP via the undocumented AllocateAndGetTcpExTableFromStack
949 function (fd.o #66060, Ralf Habacker)
950 · Fix insufficient dependency-tracking (fd.o #68505, Simon McVittie)
951 · Don't include wspiapi.h, fixing a compiler warning (fd.o #68852,
955 · add DBUS_ENABLE_ASSERT, DBUS_ENABLE_CHECKS for less confusing
956 conditionals (fd.o #66142, Chengwei Yang)
957 · improve verbose-mode output (fd.o #63047, Colin Walters)
958 · consolidate Autotools and CMake build (fd.o #64875, Ralf Habacker)
959 · fix various unused variables, unusual build configurations
960 etc. (fd.o #65712, #65990, #66005, #66257, #69165, #69410, #70218;
961 Chengwei Yang, Vasiliy Balyasnyy)
963 D-Bus 1.7.4 (2013-06-13)
966 The “but is your thread-safety thread-safe?” release.
970 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
971 of service for system services. Vulnerability reported by Alexandru Cornea.
976 • The Windows version of libdbus now contains a C++ source file, used
977 to provide global initialization when the library is loaded.
978 gcc (mingw*) users should ensure that g++ is also installed.
980 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
981 and was never the recommended option) has been removed. Expat is now a
986 • It should now be safe to call dbus_threads_init_default() from any thread,
987 at any time. Authors of loadable modules and plugins that use libdbus
988 should consider doing so during initialization.
989 (fd.o #54972, Simon McVittie)
991 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
995 · dbus-run-session: experimental new tool to start a temporary D-Bus
996 session, e.g. for regression tests or a text console, replacing
997 certain uses of dbus-launch which weren't really correct
1002 • In dbus-daemon, don't crash if a .service file starts with key=value
1003 (fd.o #60853, Chengwei Yang)
1006 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
1007 on a platform not defining LOG_PERROR, such as Solaris or QNX.
1008 This regressed in 1.7.0. (Simon)
1009 · Fix an assertion failure if we try to activate systemd services before
1010 systemd connects to the bus (fd.o #50199, Chengwei Yang)
1011 · Avoid compiler warnings for ignoring the return from write()
1015 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
1016 so that Windows finds them (fd.o #59733, Ralf Habacker)
1018 D-Bus 1.7.2 (2013-04-25)
1021 The “only partially opaque” release.
1023 Configuration changes:
1025 • On non-QNX Unix platforms, the default limit on fds per message in the
1026 session bus configuration has reduced from 4096 to 1024. The default
1027 limit used on the system bus was already 1024. On QNX, both limits are
1028 reduced further, to 128.
1032 • D-Bus Specification 0.21
1033 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
1034 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
1039 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
1040 (i.e. before allocating the slot) rather than returning junk
1041 (fd.o #63127, Dan Williams)
1043 • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker,
1047 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
1048 · Under systemd, log to syslog only, not stderr, avoiding duplication
1049 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
1050 · Under systemd, remove unnecessary dependency on syslog.socket
1051 (fd.o #63531, Cristian Rodríguez)
1052 · Include alloca.h for alloca() if available, fixing compilation on
1053 Solaris 10 (fd.o #63071, Dagobert Michelsen)
1054 · Allow use of systemd-logind without the rest of systemd
1055 (fd.o #62585, Martin Pitt)
1056 · When built with CMake, link to librt and use the right path for
1057 meinproc's XSLT stylesheets (fd.o #61637, Ralf Habacker)
1058 · Reduce the default limit on number of fds per message to 128 under
1059 QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer)
1062 · Do not claim that all bus clients have the dbus-daemon's credentials;
1063 pick up local TCPv4 clients' credentials (process ID and security
1064 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,
1067 D-Bus 1.7.0 (2013-02-22)
1070 The "Disingenuous Assertions" release.
1072 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
1073 remains the recommended version for long-term-supported distributions
1074 or the upcoming GNOME 3.8 release.
1076 Build-time configuration changes:
1078 • The --with-dbus-session-bus-default-address configure option is no longer
1079 supported. Use the new --with-dbus-session-bus-connect-address and
1080 --with-dbus-session-bus-listen-address options instead. On Windows, you
1081 usually want them to have the same argument; on Unix, the defaults are
1084 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
1085 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
1086 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
1088 • cmake/cross-compile.sh has been removed. Instead, please use a
1089 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
1090 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
1091 as documented in "info automake Cross-Compilation", and set
1092 PKG_CONFIG_PATH appropriately.
1096 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
1097 • man2html is no longer used.
1101 • D-Bus Specification 0.20
1102 · actually say that /org/freedesktop/DBus is the object that
1103 implements o.fd.DBus (fd.o #51865, Colin Walters)
1104 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
1105 · stop claiming that all basic types work just like INT32 (strings don't!)
1107 • The "source code" for the man pages is now Docbook XML, eliminating
1108 the outdated duplicate copies used when building with CMake.
1109 (fd.o #59805; Ralf Habacker, Simon McVittie)
1113 • In the activation helper, when compiled for tests, do not reset the system
1114 bus address, fixing the regression tests. (fd.o #52202, Simon)
1116 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
1117 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
1119 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,
1122 • Under CMake, prefer xmlto over meinproc (fd.o #59733, Ralf Habacker)
1124 • Stop duplicating CMake's own logic to find libexpat
1125 (fd.o #59733, Ralf Habacker)
1127 • Don't assume CMake host and build system are the same (fd.o #59733,
1130 • Avoid deprecation warnings for GLib 2.35 (fd.o #59971, Simon McVittie)
1133 · Check for functions in libpthread correctly, fixing compilation on
1134 (at least) OpenBSD (fd.o #47239, Simon)
1135 · Don't leak temporary fds pointing to /dev/null (fd.o #56927,
1137 · Update sd-daemon.[ch] from systemd (fd.o #60681)
1138 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
1141 · The default session bus listening and connecting address is now
1142 "autolaunch:", which makes D-Bus on Windows interoperate with itself
1143 and GDBus "out of the box". Use the configure options and cmake variables
1144 described above if you require a different autolaunch scope.
1145 (fd.o #38201, Simon McVittie)
1146 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
1148 • Create session.d, system.d directories under CMake (fd.o #41319,
1151 D-Bus 1.6.8 (2012-09-28)
1154 The "Fix one thing, break another" release.
1156 • Follow up to CVE-2012-3524: The additional hardening
1157 work to use __secure_getenv() as a followup to bug #52202
1158 broke certain configurations of gnome-keyring. Given
1159 the difficulty of making this work without extensive
1160 changes to gnome-keyring, use of __secure_getenv() is
1163 D-Bus 1.6.6 (2012-09-28)
1166 The "Clear the environment in your setuid binaries, please" release.
1168 • CVE-2012-3524: Don't access environment variables (fd.o #52202)
1169 Thanks to work and input from Colin Walters, Simon McVittie,
1170 Geoffrey Thomas, and others.
1172 · Fix compilation on Solaris (fd.o #53286, Jonathan Perkin)
1173 · Work around interdependent headers on OpenBSD by including sys/types.h
1174 before each use of sys/socket.h (fd.o #54418, Brad Smith)
1176 D-Bus 1.6.4 (2012-07-18)
1179 • Detect that users are "at the console" correctly when configured with
1180 a non-default path such as --enable-console-auth-dir=/run/console
1181 (fd.o #51521, Dave Reisner)
1183 • Remove an incorrect assertion from DBusTransport (fd.o #51657,
1186 • Make --enable-developer default to "no" (regression in 1.6.2;
1187 fd.o #51657, Simon McVittie)
1190 · Launch dbus-daemon correctly if its path contains a space
1191 (fd.o #49450, Wolfgang Baron)
1193 D-Bus 1.6.2 (2012-06-27)
1196 The "Ice Cabbage" release.
1198 • Change how we create /var/lib/dbus so it works under Automake >= 1.11.4
1199 (fd.o #51406, Simon McVittie)
1201 • Don't return from dbus_pending_call_set_notify with a lock held on OOM
1202 (fd.o #51032, Simon McVittie)
1204 • Disconnect "developer mode" (assertions, verbose mode etc.) from
1205 Automake maintainer mode. D-Bus developers should now configure with
1206 --enable-developer. Automake maintainer mode is now on by default;
1207 distributions can disable it with --disable-maintainer-mode.
1208 (fd.o #34671, Simon McVittie)
1210 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
1211 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
1214 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
1216 D-Bus 1.6.0 (2012-06-05)
1219 The “soul of this machine has improved” release.
1221 This version starts a new stable branch of D-Bus: only bug fixes will
1222 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
1224 Summary of changes since 1.4.x:
1227 · PTHREAD_MUTEX_RECURSIVE on Unix
1228 · compiler support for 64-bit integers (int64_t or equivalent)
1230 • D-Bus Specification v0.19
1232 • New dbus-daemon features
1233 · <allow own_prefix="com.example.Service"/> rules allow the service to
1234 own names like com.example.Service.Instance3
1235 · optional systemd integration when checking at_console policies
1236 · --nopidfile option, mainly for use by systemd
1237 · path_namespace and arg0namespace may appear in match rules
1238 · eavesdropping is disabled unless the match rule contains eavesdrop=true
1241 · functions to validate various string types (dbus_validate_path() etc.)
1242 · dbus_type_is_valid()
1243 · DBusBasicValue, a union of every basic type
1246 · removed an unsafe reimplementation of recursive mutexes
1247 · dbus-daemon no longer busy-loops if it has far too many file descriptors
1248 · dbus-daemon.exe --print-address works on Windows
1249 · all the other bug fixes from 1.4.20
1251 • Other major implementation changes
1252 · on Linux, dbus-daemon uses epoll if supported, for better scalability
1253 · dbus_threads_init() ignores its argument and behaves like
1254 dbus_threads_init_default() instead
1255 · removed the per-connection link cache, improving dbus-daemon performance
1257 • Developer features
1258 · optional Valgrind instrumentation (--with-valgrind)
1259 · optional Stats interface on the dbus-daemon (--enable-stats)
1260 · optionally abort whenever malloc() fails (--enable-embedded-tests
1261 and export DBUS_MALLOC_CANNOT_FAIL=1)
1263 Changes since 1.5.12:
1265 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
1266 spec-compliance (fd.o #48580, David Zeuthen)
1268 • Don't use install(1) within the source/build trees, fixing the build as
1269 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
1271 • Add missing commas in some tcp and nonce-tcp addresses, and remove
1272 an unused duplicate copy of the nonce-tcp transport in Windows builds
1273 (fd.o #45896, Simon McVittie)
1275 D-Bus 1.5.12 (2012-03-27)
1278 The “Big Book of Science” release.
1280 • Add public API to validate various string types:
1281 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
1282 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
1283 (fd.o #39549, Simon McVittie)
1285 • Turn DBusBasicValue into public API so bindings don't need to invent their
1286 own "union of everything" type (fd.o #11191, Simon McVittie)
1288 • Enumerate data files included in the build rather than using find(1)
1289 (fd.o #33840, Simon McVittie)
1291 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
1292 in dbus-daemon (fd.o #46273, Alban Crequy)
1295 · make dbus-daemon.exe --print-address (and --print-pid) work again
1296 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
1297 · fix duplicate case value when compiling against mingw-w64
1298 (fd.o #47321, Andoni Morales Alastruey)
1300 D-Bus 1.5.10 (2012-02-21)
1303 The "fire in Delerium" release.
1305 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
1306 and SUSv2) is now required.
1308 • D-Bus Specification 0.19:
1309 · Formally define unique connection names and well-known bus names,
1310 and document best practices for interface, bus, member and error names,
1311 and object paths (fd.o #37095, Simon McVittie)
1312 · Document the search path for session and system services on Unix, and
1313 where they should be installed by build systems (fd.o #21620, fd.o #35306;
1315 · Document the systemd transport (fd.o #35232, Lennart Poettering)
1317 • Make dbus_threads_init() use the same built-in threading implementation
1318 as dbus_threads_init_default(); the user-specified primitives that it
1319 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
1321 • Allow all configured auth mechanisms, not just one (fd.o #45106,
1324 • Improve cmake build system (Ralf Habacker):
1325 · simplify XML parser dependencies (fd.o #41027)
1326 · generate build timestamp (fd.o #41029)
1327 · only create batch files on Windows
1328 · fix option and cache syntax
1329 · add help-options target
1330 · share dbus-arch-deps.h.in with autotools rather than having our
1331 own version (fd.o #41033)
1333 • Build tests successfully with older GLib, as found in e.g. Debian 6
1334 (fd.o #41219, Simon McVittie)
1336 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
1338 • Build documentation correctly if man2html doesn't support filenames on
1339 its command-line (fd.o #43875, Jack Nagel)
1341 • Improve test coverage. To get even more coverage, run the tests with
1342 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
1344 • Reduce the size of the shared library by moving functionality only used
1345 by dbus-daemon, tests etc. into their internal library and deleting
1346 unused code (fd.o #34976, #39759; Simon McVittie)
1348 • Add dbus-daemon --nopidfile option, overriding the configuration, for
1349 setups where the default configuration must include <pidfile/> to avoid
1350 breaking traditional init, but the pid file is in fact unnecessary; use
1351 it under systemd to improve startup time a bit (fd.o #45520,
1354 • Optionally (if configured --with-valgrind) add instrumentation to debug
1355 libdbus and associated tools more meaningfully under Valgrind
1356 (fd.o #37286, Simon McVittie)
1358 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
1360 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
1362 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
1363 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
1364 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
1367 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
1371 · Replace our broken reimplementation of recursive mutexes, which has
1372 been broken since 2006, with an ordinary pthreads recursive mutex
1373 (fd.o #43744; Sigmund Augdal, Simon McVittie)
1374 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
1375 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
1376 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
1377 · When running under systemd, use it instead of ConsoleKit to check
1378 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
1379 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
1380 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
1381 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
1382 (fd.o #41218, Simon McVittie)
1383 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
1384 helper doesn't obey environment variables to avoid privilege escalation
1385 attacks, so make the system bus follow the same rules
1386 (fd.o #21620, Simon McVittie)
1389 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
1390 Jesper Dam, Ralf Habacker)
1391 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
1394 D-Bus 1.5.8 (2011-09-21)
1397 The "cross-metering" release.
1399 In addition to dead code removal and refactoring, this release contains all
1400 of the bugfixes from 1.4.16.
1402 • Clean up dead code, and make more warnings fatal in development builds
1403 (fd.o #39231, fd.o #41012; Simon McVittie)
1405 • If full test coverage is requested via --enable-tests, strictly require
1406 Python, pygobject and dbus-python, which are required by some tests; if not,
1407 and Python is missing, skip those tests rather than failing
1408 (fd.o #37847, Simon McVittie)
1410 • When using cmake, provide the same version-info API in the installed headers
1411 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
1413 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
1415 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
1417 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
1420 • Fix duplicates in authors list (Ralf Habacker)
1422 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
1423 (fd.o #39879, Chris Mayo)
1425 • Fix a small memory leak, and a failure to report errors, when updating
1426 a service file entry for activation (fd.o #39230, Simon McVittie)
1429 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
1430 Brian Cameron, Simon McVittie)
1431 · On systems that use libcap-ng but not systemd, drop supplemental groups
1432 when switching to the daemon user (Red Hat #726953, Steve Grubb)
1433 · Make the cmake build work again on GNU platforms (fd.o #29228,
1435 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
1436 like Solaris (fd.o #40313, Dagobert Michelsen)
1437 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
1438 (fd.o #40235, Simon McVittie)
1439 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
1440 (fd.o #39987, Simon McVittie)
1441 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
1442 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
1445 · Fix compilation on MSVC, which doesn't understand "inline" with its
1446 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
1447 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
1448 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
1450 D-Bus 1.5.6 (2011-07-29)
1453 The "weird, gravy-like aftertaste" release.
1455 In addition to new features and refactoring, this release contains all of the
1456 bugfixes from 1.4.14.
1458 Potentially incompatible (Bustle and similar debugging tools will need
1459 changes to work as intended):
1461 • Do not allow match rules to "eavesdrop" (receive messages intended for a
1462 different recipient) by mistake: eavesdroppers must now opt-in to this
1463 behaviour by putting "eavesdrop='true'" in the match rule, which will
1464 not have any practical effect on buses where eavesdropping is not allowed
1465 (fd.o #37890, Cosimo Alfarano)
1469 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
1470 Cosimo Alfarano, Simon McVittie)
1471 · add the "eavesdrop" keyword to match rules
1472 · define eavesdropping, unicast messages and broadcast messages
1473 · stop claiming that match rules are needed to match unicast messages to you
1474 · promote the type system to be a top-level section
1476 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
1477 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
1478 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
1480 • Consistently use atomic operations on everything that is ever manipulated
1481 via atomic ops, as was done for changes to DBusConnection's refcount in
1482 1.4.12 (fd.o #38005, Simon McVittie)
1484 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
1487 • Make "make check" in a clean tree work, by not running tests until
1488 test data has been set up (fd.o #34405, Simon McVittie)
1490 • The dbus-daemon no longer busy-loops if it has a very large number of file
1491 descriptors (fd.o #23194, Simon McVittie)
1493 • Refactor message flow through dispatching to avoid locking violations if
1494 the bus daemon's message limit is hit; remove the per-connection link cache,
1495 which was meant to improve performance, but now reduces it (fd.o #34393,
1498 • Some cmake fixes (Ralf Habacker)
1500 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
1501 Simon McVittie, Lennart Poettering)
1503 • Stop storing two extra byte order indicators in each D-Bus message
1504 (fd.o #38287, Simon McVittie)
1506 • Add an optional Stats interface which can be used to get statistics from
1507 a running dbus-daemon if enabled at configure time with --enable-stats
1508 (fd.o #34040, Simon McVittie)
1510 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
1512 • Documentation (fd.o #36156, Simon McVittie):
1513 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
1514 · install more documentation automatically, including man2html output
1515 · put dbus.devhelp in the right place (it must go in ${htmldir})
1518 · look for system services in /lib/dbus-1/system-services in addition to all
1519 the other well-known locations; note that this should always be /lib,
1520 even on platforms where shared libraries on the root FS would go in /lib64,
1521 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
1522 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
1524 • Windows-specific (Ralf Habacker):
1525 · fix use of a mutex for autolaunch server detection
1526 · don't crash on malloc failure in _dbus_printf_string_upper_bound
1528 D-Bus 1.5.4 (2011-06-10)
1531 Security (local denial of service):
1533 • Byte-swap foreign-endian messages correctly, preventing a long-standing
1534 local DoS if foreign-endian messages are relayed through the dbus-daemon
1535 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
1536 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
1540 • The constant to use for an infinite timeout now has a name,
1541 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
1542 which can be used for source compatibility with older versions of libdbus.
1544 • If GLib and DBus-GLib are already installed, more tests will be built,
1545 providing better coverage. The new tests can also be installed via
1546 ./configure --enable-installed-tests
1547 for system integration testing, if required. (fd.o #34570, Simon McVittie)
1551 • Consistently use atomic operations for the DBusConnection's refcount,
1552 fixing potential threading problems (fd.o #38005, Simon McVittie)
1554 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
1555 small (300KiB on x86-64) and it frequently doesn't work in unusual
1556 toolchains. To optimize for minimum installed size, you should benchmark
1557 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
1558 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
1560 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
1561 (fd.o #35880, Timothy Redaelli)
1563 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
1564 when not using a DESTDIR (fd.o #37870, Simon McVittie)
1566 • Windows-specific changes:
1567 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
1569 D-Bus 1.5.2 (2011-06-01)
1572 The "Boar Hunter" release.
1574 Notes for distributors:
1576 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
1577 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
1578 toolchain supports it reliably, via something like:
1580 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
1582 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
1586 • D-Bus Specification v0.17
1587 · Reserve the extra characters used in signatures by GVariant
1588 (fd.o #34529, Simon McVittie)
1589 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
1590 • Don't force -fPIE: distributions and libtool know better than we do whether
1591 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
1592 • Allow --disable-gc-sections, in case your toolchain offers the
1593 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
1594 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
1595 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
1596 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
1597 • Ensure that maintainers upload documentation with the right permissions
1598 (fd.o #36130, Simon McVittie)
1599 • Don't force users of libdbus to be linked against -lpthread, -lrt
1600 (fd.o #32827, Simon McVittie)
1601 • Log system-bus activation information to syslog (fd.o #35705,
1603 • Log messages dropped due to quotas to syslog (fd.o #35358,
1605 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
1606 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
1607 (fd.o #35228, Lennart Poettering)
1608 • In the regression tests, don't report fds as "leaked" if they were open
1609 on startup (fd.o #35173, Simon McVittie)
1610 • Make dbus-monitor bail out if asked to monitor more than one bus,
1611 rather than silently using the last one (fd.o #26548, Will Thompson)
1612 • Clarify documentation (fd.o #35182, Simon McVittie)
1613 • Clean up minor dead code and some incorrect error handling
1614 (fd.o #33128, fd.o #29881; Simon McVittie)
1615 • Check that compiler options are supported before using them (fd.o #19681,
1618 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
1620 D-Bus 1.5.0 (2011-04-11)
1623 The "you never know when you need to tow something from your giant
1624 flying shark" release.
1626 • D-Bus Specification v0.16
1627 · Add support for path_namespace and arg0namespace in match rules
1628 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
1629 · Make argNpath support object paths, not just object-path-like strings,
1630 and document it better (fd.o #31818, Will Thompson)
1631 • Let the bus daemon implement more than one interface (fd.o #33757,
1633 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
1635 • Require user intervention to compile with missing 64-bit support
1636 (fd.o #35114, Simon McVittie)
1637 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
1638 • Raise UnknownObject instead of UnknownMethod for calls to methods on
1639 paths that are not part of the object tree, and UnknownInterface for calls
1640 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
1642 D-Bus 1.4.8 (2011-04-08)
1645 The "It's like the beginning of a lobster" release.
1647 • Rename configure.in to configure.ac, and update it to modern conventions
1648 (fd.o #32245; Javier Jardón, Simon McVittie)
1649 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
1651 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
1652 --disable-x11-autolaunch configure option to prevent it altogether
1653 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
1654 • Install the documentation, and an index for Devhelp (fd.o #13495,
1655 Debian #454142; Simon McVittie, Matthias Clasen)
1656 • If checks are not disabled, check validity of string-like types and
1657 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
1658 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
1659 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
