1 D-Bus 1.9.16 (UNRELEASED)
6 D-Bus 1.9.14 (2015-03-02)
9 The “don't stand in the poison cloud” release.
13 • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They
14 were previously linked to a static version of libdbus.
16 • The tests no longer require dbus-glib in order to exercise the libdbus
17 shared library; they are always linked to libdbus now.
19 Build-time configuration:
21 • The new --enable-user-session option, off by default, can be enabled
22 by OS integrators intending to use systemd to provide a session bus
23 per user (in effect, treating all concurrent graphical and non-graphical
24 login sessions as one large session)
28 • All executables are now linked dynamically to libdbus.
29 (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker)
31 • On platforms that support them (GNU libc and possibly others),
32 libdbus now has versioned symbols for its public API.
33 All public symbols (visible in the header files) are currently
34 versioned as LIBDBUS_1_3; private symbols starting with _dbus or
35 dbus_internal have a version that changes with each release, and
36 must not be used by applications. (also fd.o #83115)
38 • New listenable address mode "unix:runtime=yes" which listens on
39 a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus
40 (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie)
42 • Add optional systemd units for a per-user bus listening on
43 $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters)
45 • On Unix platforms, both libdbus and "dbus-launch --autolaunch"
46 default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket
49 • New dbus-update-activation-environment tool uploads environment
50 variables to "dbus-daemon --session" and optionally "systemd --user",
51 primarily as a way to keep the per-user bus compatible with
52 distributions' existing X11 login scripts (also fd.o #61301)
54 • <includedir/> elements in dbus-daemon configuration are now silently
55 ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov)
57 • Add microsecond-resolution timestamps to the default output of
58 dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie)
62 • Fix a race condition in the 'monitor' test introduced in 1.9.10
63 (fd.o #89222, Simon McVittie)
65 D-Bus 1.9.12 (2015-02-19)
68 The “monster lasagna” release.
72 • Ducktype and yelp-tools are now required to build complete documentation
73 (they are optional for normal builds).
77 • D-Bus Specification version 0.26
78 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID
79 · document the BecomeMonitor method
81 • On Linux, add LinuxSecurityLabel to GetConnectionCredentials
82 (fd.o #89041; Tyler Hicks, Simon McVittie)
84 • On Linux, add support for AppArmor mediation of message sending and
85 receiving and name ownership (paralleling existing SELinux mediation
86 support), and eavesdropping (a new check, currently AppArmor-specific)
87 (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie)
89 • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings
90 that have printable ASCII contents; we previously only did this for
91 unterminated bytestrings (fd.o #89109, Simon McVittie)
93 • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall)
95 • On Windows, add WindowsSID to GetConnectionCredentials
96 (fd.o #54445, Ralf Habacker)
98 • Improve clarity of dbus-monitor --profile output and add more columns
99 (fd.o #89165, Ralf Habacker)
101 • Add a man page for dbus-test-tool, and build it under CMake as well
102 as Autotools (fd.o#89086, Simon McVittie)
104 • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API
105 to control it at runtime, overriding the DBUS_VERBOSE environment variable
106 (fd.o #88896, Ralf Habacker)
110 • Reduce the number of file descriptors used in the fd-passing test,
111 avoiding failure under the default Linux fd limit, and automatically
112 skip it if the rlimit is too small (fd.o #88998, Simon McVittie)
114 D-Bus 1.9.10 (2015-02-09)
117 The “sad cyborgs” release.
119 Security fixes merged from 1.8.16:
121 • Do not allow non-uid-0 processes to send forged ActivationFailure
122 messages. On Linux systems with systemd activation, this would
123 allow a local denial of service: unprivileged processes could
124 flood the bus with these forged messages, winning the race with
125 the actual service activation and causing an error reply
126 to be sent back when service auto-activation was requested.
127 This does not prevent the real service from being started,
128 so the attack only works while the real service is not running.
129 (CVE-2015-0245, fd.o #88811; Simon McVittie)
133 • The new Monitoring interface in the dbus-daemon lets dbus-monitor and
134 similar tools receive messages without altering the security properties
135 of the system bus, by calling the new BecomeMonitor method on a
136 private connection. This bypasses the normal <allow> and <deny> rules
137 entirely, so to preserve normal message-privacy assumptions, only root
138 is allowed to do this on the system bus. Restricted environments,
139 such as Linux with LSMs, should lock down access to the Monitoring
140 interface. (fd.o #46787, Simon McVittie)
142 • dbus-monitor uses BecomeMonitor to capture more traffic, if the
143 dbus-daemon supports it and access permissions allow it.
144 It still supports the previous approach ("eavesdropping" match rules)
145 for compatibility with older bus daemons. (fd.o #46787, Simon)
147 • dbus-monitor can now log the message stream as binary data for later
148 analysis, with either no extra framing beyond the normal D-Bus headers,
149 or libpcap-compatible framing treating each D-Bus message
150 as a captured packet. (fd.o #46787, Simon)
154 • Fix some CMake build regressions (fd.o #88964, Ralf Habacker)
156 • On Unix, forcibly terminate regression tests after 60 seconds to
157 prevent them from blocking continuous integration frameworks
160 D-Bus 1.9.8 (2015-02-03)
163 The “all the types of precipitation” release.
167 • full test coverage now requires GLib 2.36
168 • full test coverage now requires PyGI (PyGObject 3,
169 "import gi.repository.GObject") instead of the
170 obsolete PyGObject 2 ("import gobject")
174 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
176 • better regression test coverage, including systemd activation
177 (fd.o #57952, #88810; Simon McVittie)
181 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
182 turned off (fd.o #88808, Simon McVittie)
184 • TCP sockets on Windows no longer fail to listen approximately 1 time
185 in 256, caused by a logic error that should have always made it fail but
186 was mitigated by incorrect endianness for the port number
187 (fd.o #87999, Ralf Habacker)
189 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
191 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
192 previous 64, completing a previous fix which only worked under
193 Autotools (fd.o #71297, Ralf Habacker)
195 • on Windows, if the IP family is unspecified only use IPv4,
196 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
198 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
200 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
202 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
205 D-Bus 1.9.6 (2015-01-05)
208 The “I do have a bread knife” release.
212 • Do not allow calls to UpdateActivationEnvironment from uids other than
213 the uid of the dbus-daemon. If a system service installs unsafe
214 security policy rules that allow arbitrary method calls
215 (such as CVE-2014-8148) then this prevents memory consumption and
216 possible privilege escalation via UpdateActivationEnvironment.
218 We believe that in practice, privilege escalation here is avoided
219 by dbus-daemon-launch-helper sanitizing its environment; but
220 it seems better to be safe.
222 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
223 on object paths other than /org/freedesktop/DBus. Some system services
224 install unsafe security policy rules that allow arbitrary method calls
225 to any destination, method and interface with a specified object path;
226 while less bad than allowing arbitrary method calls, these security
227 policies are still harmful, since dbus-daemon normally offers the
228 same API on all object paths and other system services might behave
233 • Add missing initialization so GetExtendedTcpTable doesn't crash on
234 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
236 D-Bus 1.9.4 (2014-11-24)
239 The “extra-sturdy caramel” release.
243 • Partially revert the CVE-2014-3639 patch by increasing the default
244 authentication timeout on the system bus from 5 seconds back to 30
245 seconds, since this has been reported to cause boot regressions for
246 some users, mostly with parallel boot (systemd) on slower hardware.
248 On fast systems where local users are considered particularly hostile,
249 administrators can return to the 5 second timeout (or any other value
250 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
253 <limit name="auth_timeout">5000</limit>
256 (fd.o #86431, Simon McVittie)
258 • Add a message in syslog/the Journal when the auth_timeout is exceeded
259 (fd.o #86431, Simon McVittie)
261 • Send back an AccessDenied error if the addressed recipient is not allowed
262 to receive a message (and in builds with assertions enabled, don't
263 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
265 D-Bus 1.9.2 (2014-11-10)
268 The “structurally unsound flapjack” release.
272 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
273 so that CVE-2014-3636 part A cannot exhaust the system bus'
274 file descriptors, completing the incomplete fix in 1.8.8.
275 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
279 • D-Bus Specification version 0.25
280 · new value 'const' for EmitsChangedSignal annotation
281 (fd.o #72958, Lennart Poettering)
282 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
283 (fd.o #83449; Lennart Poettering, Simon McVittie)
284 · annotate table of types with reserved/basic/container, and for
285 basic types, fixed/string-like
286 · clarify arbitrary limits by quoting them in mebibytes
288 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
289 (fd.o #83449, Simon McVittie)
291 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
292 useful for debugging and performance testing:
293 · dbus-test-tool spam: send repeated messages
294 · dbus-test-tool echo: send an empty reply for all method calls
295 · dbus-test-tool black-hole: do not reply to method calls
296 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
298 • Add support for process ID in credentials-passing on NetBSD
299 (fd.o #69702, Patrick Welche)
301 • Add an example script to find potentially undesired match rules
302 (fd.o #84598, Alban Crequy)
304 • Document the central assumption that makes our use of credentials-passing
305 secure (fd.o #83499, Simon McVittie)
307 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
308 and add some links to GDBus and QtDBus documentation (fd.o #25140,
313 • Use a less confusing NoReply message when disconnected with a reply pending
314 (fd.o #76112, Simon McVittie)
316 • Make the .pc file relocatable by letting pkg-config do all variable
317 expansion itself (fd.o #75858, Руслан Ижбулатов)
319 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
320 (fd.o #85563, Patrick Welche)
322 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
324 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
325 do not lose the exec() errno (fd.o #24821, Simon McVittie)
327 • Do not fail the tests if a parent process has leaked non-close-on-exec
328 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
330 • Do not fail the tests on Unix platforms with incomplete
331 credentials-passing support, but do fail if we can't pass credentials
332 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
333 (fd.o #69702, Simon McVittie)
335 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
336 when building with cmake, and expand test coverage there
337 (fd.o #73689; Ralf Habacker, Simon McVittie)
339 D-Bus 1.9.0 (2014-10-01)
342 The “tiered cheeses” release.
346 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
347 requires either the libsystemd or libsd-daemon shared library, dropping the
348 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
350 Build-time configuration changes:
352 • The Stats interface is now enabled by default, and locked-down to
353 root-only on the system bus. Configure with --disable-stats
354 to disable it altogether on memory- or disk-constrained systems,
355 or see ${docdir}/examples/ to open it up to non-root users on the
356 system bus or restrict access on the session bus.
357 (fd.o #80759; Simon McVittie, Alban Crequy)
359 • The CMake build system now builds the same shared library name as Autotools
360 on at least Linux and Windows:
361 - on Linux (and perhaps other Unix platforms), it previously built
362 libdbus-1.so, but now builds libdbus-1.so.3.* with development
363 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
364 - on Windows, it previously built either libdbus-1.dll (release) or
365 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
366 libdbus-1.dll for compatibility with older applications.
367 (fd.o #74117, Ralf Habacker)
371 • D-Bus Specification version 0.24
372 · document how to quote match rules (fd.o #24307, Simon McVittie)
373 · explicitly say that most message types never expect a reply
374 regardles of whether they have NO_REPLY_EXPECTED
375 (fd.o #75749, Simon McVittie)
377 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
378 initial latency (fd.o #75544, Matt Hoosier)
380 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
381 (fd.o #69702, Patrick Welche)
383 • in dbus-monitor, print more information about file descriptors
384 (fd.o #80603, Alban Crequy)
386 • do not install system bus configuration if built for Windows
387 (fd.o #83583; Ralf Habacker, Simon McVittie)
389 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
391 • Add a regression test for file descriptor passing (fd.o #83622,
396 • fix an incorrect error message if a Unix socket path is too long
397 (fd.o #73887, Antoine Jacoutot)
399 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
400 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
402 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
403 in ps(1) (fd.o #69716, Chengwei Yang)
405 • avoid calling poll() with timeout < -1, which is considered invalid
406 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
408 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
409 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
410 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
412 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
414 • Documentation improvements
415 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
417 • in dbus-monitor, do not leak file descriptors that we have monitored
418 (fd.o #80603, Alban Crequy)
420 • Set the close-on-exec flag for the inotify file descriptor, even
421 if built with CMake or older libc (fd.o #73689, Simon McVittie)
423 • Remove some LGPL code from the Windows dbus-daemon
424 (fd.o #57272, Ralf Habacker)
426 D-Bus 1.8.8 (2014-09-16)
429 The "smashy smashy egg man" release.
433 • Do not accept an extra fd in the padding of a cmsg message, which
434 could lead to a 4-byte heap buffer overrun.
435 (CVE-2014-3635, fd.o #83622; Simon McVittie)
437 • Reduce default for maximum Unix file descriptors passed per message
438 from 1024 to 16, preventing a uid with the default maximum number of
439 connections from exhausting the system bus' file descriptors under
440 Linux's default rlimit. Distributors or system administrators with a
441 more restrictive fd limit may wish to reduce these limits further.
443 Additionally, on Linux this prevents a second denial of service
444 in which the dbus-daemon can be made to exceed the maximum number
445 of fds per sendmsg() and disconnect the process that would have
447 (CVE-2014-3636, fd.o #82820; Alban Crequy)
449 • Disconnect connections that still have a fd pending unmarshalling after
450 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
451 removing the possibility of creating an abusive connection that cannot be
452 disconnected by setting up a circular reference to a connection's
454 (CVE-2014-3637, fd.o #80559; Alban Crequy)
456 • Reduce default for maximum pending replies per connection from 8192 to 128,
457 mitigating an algorithmic complexity denial-of-service attack
458 (CVE-2014-3638, fd.o #81053; Alban Crequy)
460 • Reduce default for authentication timeout on the system bus from
461 30 seconds to 5 seconds, avoiding denial of service by using up
462 all unauthenticated connection slots; and when all unauthenticated
463 connection slots are used up, make new connection attempts block
464 instead of disconnecting them.
465 (CVE-2014-3639, fd.o #80919; Alban Crequy)
469 • Check for libsystemd from systemd >= 209, falling back to
470 the older separate libraries if not found (Umut Tezduyar Lindskog,
473 • On Linux, use prctl() to disable core dumps from a test executable
474 that deliberately raises SIGSEGV to test dbus-daemon's handling
475 of that condition (fd.o #83772, Simon McVittie)
477 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
480 • Improve documentation for running tests on Windows (fd.o #41252,
483 D-Bus 1.8.6 (2014-06-02)
488 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
489 the message. This prevents an attack in which a malicious client can
490 make dbus-daemon disconnect a system service, which is a local
492 (fd.o #80163, CVE-2014-3532; Alban Crequy)
494 • Track remaining Unix file descriptors correctly when more than one
495 message in quick succession contains fds. This prevents another attack
496 in which a malicious client can make dbus-daemon disconnect a system
498 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
499 Simon McVittie, Alban Crequy)
503 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
504 attach to a session, kill the dbus-daemon as intended
505 (fd.o #74698, Роман Донченко)
507 D-Bus 1.8.4 (2014-06-10)
512 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
513 flaw in dbus-daemon, part of the reference implementation of D-Bus.
514 Additionally, in highly unusual environments the same flaw could lead to
515 a side channel between processes that should not be able to communicate.
516 (CVE-2014-3477, fd.o #78979)
518 D-Bus 1.8.2 (2014-04-30)
521 The “nobody wants red” release.
525 • in the CMake build system, add some hints for Linux users cross-compiling
526 Windows D-Bus binaries to be able to run tests under Wine
527 (fd.o #41252, Ralf Habacker)
529 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
533 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
534 to /var/lib/dbus/machine-id instead of generating an entirely new ID
535 (fd.o #77941, Simon McVittie)
537 • if dbus-launch receives an X error very quickly, do not kill
538 unrelated processes (fd.o #74698, Роман Донченко)
540 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
541 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
543 • cope with \r\n newlines in regression tests, since on Windows,
544 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
546 D-Bus 1.8.0 (2014-01-20)
549 The “Wolverine distrusts my printer” release.
551 This starts a new stable branch. The 1.6.x branch is now considered to be
552 outdated, and will only receive fixes for serious bugs such as security
553 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
554 are unlikely to get any more releases, but if distributors still need to
555 support them, please share security patches via upstream.
557 Summary of changes since 1.6.x:
559 • libdbus always behaves as if dbus_threads_init_default() had been called
560 (thread-safety by default)
561 • new dbus-run-session tool, replacing certain misuses of dbus-launch
562 • dbus-monitor can talk to outdated versions of dbus-daemon again
563 • new org.freedesktop.DBus.GetConnectionCredentials method
564 • GetConnectionUnixProcessID also works correctly on Windows, returning
565 the Windows process ID
566 • GetConnectionWindowsSID returns the correct SID on Windows
567 • expat is required, libxml2 can no longer be used as a substitute
568 • the userDB cache is required, and cannot be disabled
569 • a 64-bit integer type (either int, long, long long or _int64) is required
570 • better systemd-journald integration on Linux
571 • fixed long-standing fd and array leaks when failing to parse a message
572 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
573 when using certain object-path allocation patterns, notably in Avahi
574 • better defaults for Windows support
575 • better CMake support
576 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
577 • the source language for the man pages is now Docbook XML
579 Enhancements since 1.7.10:
581 • Enhance the CMake build system to check for GLib and compile/run
582 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
586 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
589 • fix compilation of systemd journal support on older systemd versions where
590 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
592 • fix compilation on older MSVC versions by including stdlib.h
593 (fd.o #73455, Ralf Habacker)
595 • Allow <allow_anonymous/> to appear in an included configuration file
596 (fd.o #73475, Matt Hoosier)
598 Test behaviour changes since 1.7.10:
600 • If the tests crash with an assertion failure, they no longer default to
601 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
602 environment if you want the old behaviour.
604 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
605 can be run with an external dbus-daemon by setting
606 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
607 an unusually-configured dbus-daemon are skipped.
609 D-Bus 1.7.10 (2014-01-06)
612 The “weighted companion cube” release.
614 This is a release candidate for D-Bus 1.8.
616 D-Bus Specification 0.23:
618 • don't require messages with no INTERFACE to be dispatched
619 (fd.o #68597, Simon McVittie)
621 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
624 • define "listenable" and "connectable" addresses, and discuss
625 the difference (fd.o #61303, Simon McVittie)
629 • support printing Unix file descriptors in dbus-send, dbus-monitor
630 (fd.o #70592, Robert Ancell)
632 • don't install systemd units if --disable-systemd is given
633 (fd.o #71818, Chengwei Yang)
637 • don't leak memory on out-of-memory while listing activatable or
638 active services (fd.o #71526, Radoslaw Pajak)
640 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
642 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
644 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
645 and DBUS__SEND_MSG are numerically equal to their values in the
646 reference policy (fd.o #88719, osmond sun)
648 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
649 (fd.o #71366, Matt Fischer)
651 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
652 winsock2.h (fd.o #71405, Matt Fischer)
654 • do not return failure from _dbus_read_nonce() with no error set,
655 preventing a potential crash (fd.o #72298, Chengwei Yang)
657 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
658 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
660 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
661 which doesn't do anything anyway on at least Linux and FreeBSD
662 (fd.o #69492, Simon McVittie)
664 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
665 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
666 for credentials more correctly (fd.o #69492, Simon McVittie)
668 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
669 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
672 • refresh cached policy rules for existing connections when bus
673 configuration changes (fd.o #39463, Chengwei Yang)
675 D-Bus 1.7.8 (2013-11-01)
678 The “extreme hills” release.
682 • If systemd support is enabled, libsystemd-journal is now required.
686 • When activating a non-systemd service under systemd, annotate its
687 stdout/stderr with its bus name in the Journal. Known limitation:
688 because the socket is opened before forking, the process will still be
689 logged as if it had dbus-daemon's process ID and user ID.
690 (fd.o #68559, Chengwei Yang)
692 • Document more configuration elements in dbus-daemon(1)
693 (fd.o #69125, Chengwei Yang)
697 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
698 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
700 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
701 disallowed method calls to the audit log, fixing a regression in 1.7.6
702 (fd.o #49062, Colin Walters)
704 • path_namespace='/' in match rules incorrectly matched nothing; it
705 now matches everything. (fd.o #70799, Simon McVittie)
707 D-Bus 1.7.6 (2013-10-09)
710 The “CSI Shrewsbury” release.
712 Build-time configuration changes:
714 • Directory change notification via dnotify on Linux is no longer
715 supported; it hadn't compiled successfully since 2010 in any case.
716 If you don't have inotify (Linux) or kqueue (*BSD), you will need
717 to send SIGHUP to the dbus-daemon when its configuration changes.
718 (fd.o #33001, Chengwei Yang)
720 • Compiling with --disable-userdb-cache is no longer supported;
721 it didn't work since at least 2008, and would lead to an extremely
722 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
725 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
726 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
727 with the Autotools build system. (fd.o #66142, Chengwei Yang)
729 • --with-valgrind=auto enables Valgrind instrumentation if and only if
730 valgrind headers are available. The default is still --with-valgrind=no.
731 (fd.o #56925, Simon McVittie)
735 • Platforms with no 64-bit integer type are no longer supported.
736 (fd.o #65429, Simon McVittie)
738 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
740 • Full test coverage no longer requires dbus-glib, although the tests do not
741 exercise the shared library (only a static copy) if dbus-glib is missing.
742 (fd.o #68852, Simon McVittie)
746 • D-Bus Specification 0.22
747 · Document GetAdtAuditSessionData() and
748 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
749 · Fix example .service file (fd.o #66481, Chengwei Yang)
750 · Don't claim D-Bus is "low-latency" (lower than what?), just
751 give factual statements about it supporting async use
752 (fd.o #65141, Justin Lee)
753 · Document the contents of .service files, and the fact that
754 system services' filenames are constrained
755 (fd.o #66608; Simon McVittie, Chengwei Yang)
757 • Be thread-safe by default on all platforms, even if
758 dbus_threads_init_default() has not been called. For compatibility with
759 older libdbus, library users should continue to call
760 dbus_threads_init_default(): it is harmless to do so.
761 (fd.o #54972, Simon McVittie)
763 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
765 • New API: dbus_setenv(), a simple wrapper around setenv().
766 Note that this is not thread-safe. (fd.o #39196, Simon)
768 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
769 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
770 (connect to a given bus, like dbus-monitor --address=ADDRESS).
771 dbus-send --address still exists for backwards compatibility,
772 but is no longer documented. (fd.o #48816, Andrey Mazo)
775 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
780 • Avoid an infinite busy-loop if a signal interrupts waitpid()
781 (fd.o #68945, Simon McVittie)
783 • Clean up memory for parent nodes when objects are unexported
784 (fd.o #60176, Thomas Fitzsimmons)
786 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
787 documented. Previously, it assumed its second parameter was TRUE.
788 (fd.o #69165, Chengwei Yang)
790 • Escape addresses containing non-ASCII characters correctly
791 (fd.o #53499, Chengwei Yang)
793 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
795 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
796 (fd.o #65923, Chengwei Yang)
798 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
799 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
801 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
802 that was never va_start()ed (fd.o #66300, Chengwei Yang)
804 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
806 • fix a regression test on platforms with strict alignment (fd.o #67279,
809 • Avoid calling function parameters "interface" since certain Windows headers
810 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
812 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
814 • Various thread-safety improvements to static variables (fd.o #68610,
817 • Make "make -j check" work (fd.o #68852, Simon McVittie)
819 • Fix a NULL pointer dereference on an unlikely error path
820 (fd.o #69327, Sviatoslav Chagaev)
822 • Improve valgrind memory pool tracking (fd.o #69326,
825 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
828 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
829 (fd.o #66107, Chengwei Yang)
832 · If accept4() fails with EINVAL, as it can on older Linux kernels
833 with newer glibc, try accept() instead of going into a busy-loop.
834 (fd.o #69026, Chengwei Yang)
835 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
836 for instance on Hurd or older Linux with a new glibc, try without
837 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)
838 · Fix a file descriptor leak on an error code path.
839 (fd.o #69182, Sviatoslav Chagaev)

843 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
844 · Use dbus-launch from the builddir for testing, not the installed copy
845 (fd.o #37849, Chengwei Yang)
846 · Fix compilation if writev() is unavailable (fd.o #69409,
848 · Remove broken support for LOCAL_CREDS credentials passing, and
849 document where each credential-passing scheme is used (fd.o #60340,
851 · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality
852 (fd.o #35881, #69787; Chengwei Yang)
853 · dbus-monitor: be portable to NetBSD (fd.o #69842, Chengwei Yang)
854 · dbus-launch: stop using non-portable asprintf (fd.o #37849, Simon)
855 · Improve error reporting from the setuid activation helper (fd.o #66728,

872 · consolidate Autotools and CMake build (fd.o #64875, Ralf Habacker)
873 · fix various unused variables, unusual build configurations
874 etc. (fd.o #65712, #65990, #66005, #66257, #69165, #69410, #70218;
875 Chengwei Yang, Vasiliy Balyasnyy)
877 D-Bus 1.7.4 (2013-06-13)
880 The “but is your thread-safety thread-safe?” release.
884 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
885 of service for system services. Vulnerability reported by Alexandru Cornea.
890 • The Windows version of libdbus now contains a C++ source file, used
891 to provide global initialization when the library is loaded.
892 gcc (mingw*) users should ensure that g++ is also installed.
894 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
895 and was never the recommended option) has been removed. Expat is now a
900 • It should now be safe to call dbus_threads_init_default() from any thread,
901 at any time. Authors of loadable modules and plugins that use libdbus
902 should consider doing so during initialization.
903 (fd.o #54972, Simon McVittie)
905 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
909 · dbus-run-session: experimental new tool to start a temporary D-Bus
910 session, e.g. for regression tests or a text console, replacing
911 certain uses of dbus-launch which weren't really correct
916 • In dbus-daemon, don't crash if a .service file starts with key=value
917 (fd.o #60853, Chengwei Yang)
920 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
921 on a platform not defining LOG_PERROR, such as Solaris or QNX.
922 This regressed in 1.7.0. (Simon)
923 · Fix an assertion failure if we try to activate systemd services before
924 systemd connects to the bus (fd.o #50199, Chengwei Yang)
925 · Avoid compiler warnings for ignoring the return from write()
929 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
930 so that Windows finds them (fd.o #59733, Ralf Habacker)
932 D-Bus 1.7.2 (2013-04-25)
935 The “only partially opaque” release.
937 Configuration changes:
939 • On non-QNX Unix platforms, the default limit on fds per message in the
940 session bus configuration has reduced from 4096 to 1024. The default
941 limit used on the system bus was already 1024. On QNX, both limits are
942 reduced further, to 128.
946 • D-Bus Specification 0.21
947 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
948 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
953 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
954 (i.e. before allocating the slot) rather than returning junk
955 (fd.o #63127, Dan Williams)
957 • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker,
961 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
962 · Under systemd, log to syslog only, not stderr, avoiding duplication
963 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
964 · Under systemd, remove unnecessary dependency on syslog.socket
965 (fd.o #63531, Cristian Rodríguez)
966 · Include alloca.h for alloca() if available, fixing compilation on
967 Solaris 10 (fd.o #63071, Dagobert Michelsen)
968 · Allow use of systemd-logind without the rest of systemd
969 (fd.o #62585, Martin Pitt)
970 · When built with CMake, link to librt and use the right path for
971 meinproc's XSLT stylesheets (fd.o #61637, Ralf Habacker)
972 · Reduce the default limit on number of fds per message to 128 under
973 QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer)
976 · Do not claim that all bus clients have the dbus-daemon's credentials;
977 pick up local TCPv4 clients' credentials (process ID and security
978 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,
981 D-Bus 1.7.0 (2013-02-22)
984 The "Disingenuous Assertions" release.
986 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
987 remains the recommended version for long-term-supported distributions
988 or the upcoming GNOME 3.8 release.
990 Build-time configuration changes:
992 • The --with-dbus-session-bus-default-address configure option is no longer
993 supported. Use the new --with-dbus-session-bus-connect-address and
994 --with-dbus-session-bus-listen-address options instead. On Windows, you
995 usually want them to have the same argument; on Unix, the defaults are
998 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
999 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
1000 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
1002 • cmake/cross-compile.sh has been removed. Instead, please use a
1003 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
1004 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
1005 as documented in "info automake Cross-Compilation", and set
1006 PKG_CONFIG_PATH appropriately.
1010 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
1011 • man2html is no longer used.
1015 • D-Bus Specification 0.20
1016 · actually say that /org/freedesktop/DBus is the object that
1017 implements o.fd.DBus (fd.o #51865, Colin Walters)
1018 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
1019 · stop claiming that all basic types work just like INT32 (strings don't!)
1021 • The "source code" for the man pages is now Docbook XML, eliminating
1022 the outdated duplicate copies used when building with CMake.
1023 (fd.o #59805; Ralf Habacker, Simon McVittie)
1027 • In the activation helper, when compiled for tests, do not reset the system
1028 bus address, fixing the regression tests. (fd.o #52202, Simon)
1030 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
1031 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
1033 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

1051 · Update sd-daemon.[ch] from systemd (fd.o #60681)
1052 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
1055 · The default session bus listening and connecting address is now
1056 "autolaunch:", which makes D-Bus on Windows interoperate with itself
1057 and GDBus "out of the box". Use the configure options and cmake variables
1058 described above if you require a different autolaunch scope.
1059 (fd.o #38201, Simon McVittie)
1060 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
1062 • Create session.d, system.d directories under CMake (fd.o #41319,
1065 D-Bus 1.6.8 (2012-09-28)
1068 The "Fix one thing, break another" release.
1070 • Follow up to CVE-2012-3524: The additional hardening
1071 work to use __secure_getenv() as a followup to bug #52202
1072 broke certain configurations of gnome-keyring. Given
1073 the difficulty of making this work without extensive
1074 changes to gnome-keyring, use of __secure_getenv() is
1077 D-Bus 1.6.6 (2012-09-28)
1080 The "Clear the environment in your setuid binaries, please" release.
1082 • CVE-2012-3524: Don't access environment variables (fd.o #52202)

1090 D-Bus 1.6.4 (2012-07-18)
1093 • Detect that users are "at the console" correctly when configured with
1094 a non-default path such as --enable-console-auth-dir=/run/console
1095 (fd.o #51521, Dave Reisner)

1115 • Don't return from dbus_pending_call_set_notify with a lock held on OOM
1116 (fd.o #51032, Simon McVittie)
1118 • Disconnect "developer mode" (assertions, verbose mode etc.) from
1119 Automake maintainer mode. D-Bus developers should now configure with
1120 --enable-developer. Automake maintainer mode is now on by default;
1121 distributions can disable it with --disable-maintainer-mode.
1122 (fd.o #34671, Simon McVittie)
1124 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
1125 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
1128 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
1130 D-Bus 1.6.0 (2012-06-05)
1133 The “soul of this machine has improved” release.
1135 This version starts a new stable branch of D-Bus: only bug fixes will

1177 Changes since 1.5.12:
1179 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
1180 spec-compliance (fd.o #48580, David Zeuthen)
1182 • Don't use install(1) within the source/build trees, fixing the build as
1183 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
1185 • Add missing commas in some tcp and nonce-tcp addresses, and remove
1186 an unused duplicate copy of the nonce-tcp transport in Windows builds
1187 (fd.o #45896, Simon McVittie)
1189 D-Bus 1.5.12 (2012-03-27)
1192 The “Big Book of Science” release.
1194 • Add public API to validate various string types:
1195 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
1196 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
1197 (fd.o #39549, Simon McVittie)
1199 • Turn DBusBasicValue into public API so bindings don't need to invent their
1200 own "union of everything" type (fd.o #11191, Simon McVittie)
1202 • Enumerate data files included in the build rather than using find(1)
1203 (fd.o #33840, Simon McVittie)
1205 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
1206 in dbus-daemon (fd.o #46273, Alban Crequy)
1209 · make dbus-daemon.exe --print-address (and --print-pid) work again
1210 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
1211 · fix duplicate case value when compiling against mingw-w64
1212 (fd.o #47321, Andoni Morales Alastruey)
1214 D-Bus 1.5.10 (2012-02-21)
1217 The "fire in Delerium" release.
1219 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
1220 and SUSv2) is now required.
1222 • D-Bus Specification 0.19:
1223 · Formally define unique connection names and well-known bus names,
1224 and document best practices for interface, bus, member and error names,
1225 and object paths (fd.o #37095, Simon McVittie)
1226 · Document the search path for session and system services on Unix, and
1227 where they should be installed by build systems (fd.o #21620, fd.o #35306;
1229 · Document the systemd transport (fd.o #35232, Lennart Poettering)
1231 • Make dbus_threads_init() use the same built-in threading implementation
1232 as dbus_threads_init_default(); the user-specified primitives that it
1233 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
1235 • Allow all configured auth mechanisms, not just one (fd.o #45106,
1238 • Improve cmake build system (Ralf Habacker):
1239 · simplify XML parser dependencies (fd.o #41027)
1240 · generate build timestamp (fd.o #41029)
1241 · only create batch files on Windows
1242 · fix option and cache syntax
1243 · add help-options target
1244 · share dbus-arch-deps.h.in with autotools rather than having our
1245 own version (fd.o #41033)
1247 • Build tests successfully with older GLib, as found in e.g. Debian 6
1248 (fd.o #41219, Simon McVittie)
1250 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
1252 • Build documentation correctly if man2html doesn't support filenames on
1253 its command-line (fd.o #43875, Jack Nagel)
1255 • Improve test coverage. To get even more coverage, run the tests with
1256 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
1258 • Reduce the size of the shared library by moving functionality only used
1259 by dbus-daemon, tests etc. into their internal library and deleting
1260 unused code (fd.o #34976, #39759; Simon McVittie)
1262 • Add dbus-daemon --nopidfile option, overriding the configuration, for
1263 setups where the default configuration must include <pidfile/> to avoid
1264 breaking traditional init, but the pid file is in fact unnecessary; use
1265 it under systemd to improve startup time a bit (fd.o #45520,
1268 • Optionally (if configured --with-valgrind) add instrumentation to debug
1269 libdbus and associated tools more meaningfully under Valgrind
1270 (fd.o #37286, Simon McVittie)
1272 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
1274 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
1276 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
1277 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
1278 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
1281 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
1285 · Replace our broken reimplementation of recursive mutexes, which has
1286 been broken since 2006, with an ordinary pthreads recursive mutex
1287 (fd.o #43744; Sigmund Augdal, Simon McVittie)
1288 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
1289 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
1290 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
1291 · When running under systemd, use it instead of ConsoleKit to check
1292 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
1293 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
1294 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
1295 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
1296 (fd.o #41218, Simon McVittie)
1297 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
1298 helper doesn't obey environment variables to avoid privilege escalation
1299 attacks, so make the system bus follow the same rules
1300 (fd.o #21620, Simon McVittie)
1303 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
1304 Jesper Dam, Ralf Habacker)
1305 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
1308 D-Bus 1.5.8 (2011-09-21)
1311 The "cross-metering" release.
1313 In addition to dead code removal and refactoring, this release contains all
1314 of the bugfixes from 1.4.16.
1316 • Clean up dead code, and make more warnings fatal in development builds
1317 (fd.o #39231, fd.o #41012; Simon McVittie)
1319 • If full test coverage is requested via --enable-tests, strictly require
1320 Python, pygobject and dbus-python, which are required by some tests; if not,
1321 and Python is missing, skip those tests rather than failing
1322 (fd.o #37847, Simon McVittie)
1324 • When using cmake, provide the same version-info API in the installed headers
1325 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
1327 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
1329 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
1331 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
1334 • Fix duplicates in authors list (Ralf Habacker)
1336 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
1337 (fd.o #39879, Chris Mayo)
1339 • Fix a small memory leak, and a failure to report errors, when updating
1340 a service file entry for activation (fd.o #39230, Simon McVittie)
1343 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
1344 Brian Cameron, Simon McVittie)
1345 · On systems that use libcap-ng but not systemd, drop supplemental groups
1346 when switching to the daemon user (Red Hat #726953, Steve Grubb)
1347 · Make the cmake build work again on GNU platforms (fd.o #29228,
1349 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
1350 like Solaris (fd.o #40313, Dagobert Michelsen)
1351 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
1352 (fd.o #40235, Simon McVittie)
1353 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
1354 (fd.o #39987, Simon McVittie)
1355 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
1356 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
1359 · Fix compilation on MSVC, which doesn't understand "inline" with its
1360 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
1361 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
1362 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
1364 D-Bus 1.5.6 (2011-07-29)
1367 The "weird, gravy-like aftertaste" release.
1369 In addition to new features and refactoring, this release contains all of the
1370 bugfixes from 1.4.14.
1372 Potentially incompatible (Bustle and similar debugging tools will need
1373 changes to work as intended):
1375 • Do not allow match rules to "eavesdrop" (receive messages intended for a
1376 different recipient) by mistake: eavesdroppers must now opt-in to this
1377 behaviour by putting "eavesdrop='true'" in the match rule, which will
1378 not have any practical effect on buses where eavesdropping is not allowed
1379 (fd.o #37890, Cosimo Alfarano)
1383 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
1384 Cosimo Alfarano, Simon McVittie)
1385 · add the "eavesdrop" keyword to match rules
1386 · define eavesdropping, unicast messages and broadcast messages
1387 · stop claiming that match rules are needed to match unicast messages to you
1388 · promote the type system to be a top-level section
1390 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
1391 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
1392 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
1394 • Consistently use atomic operations on everything that is ever manipulated
1395 via atomic ops, as was done for changes to DBusConnection's refcount in
1396 1.4.12 (fd.o #38005, Simon McVittie)
1398 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
1401 • Make "make check" in a clean tree work, by not running tests until
1402 test data has been set up (fd.o #34405, Simon McVittie)
1404 • The dbus-daemon no longer busy-loops if it has a very large number of file
1405 descriptors (fd.o #23194, Simon McVittie)
1407 • Refactor message flow through dispatching to avoid locking violations if
1408 the bus daemon's message limit is hit; remove the per-connection link cache,
1409 which was meant to improve performance, but now reduces it (fd.o #34393,
1412 • Some cmake fixes (Ralf Habacker)
1414 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
1415 Simon McVittie, Lennart Poettering)
1417 • Stop storing two extra byte order indicators in each D-Bus message
1418 (fd.o #38287, Simon McVittie)
1420 • Add an optional Stats interface which can be used to get statistics from
1421 a running dbus-daemon if enabled at configure time with --enable-stats
1422 (fd.o #34040, Simon McVittie)
1424 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
1426 • Documentation (fd.o #36156, Simon McVittie):
1427 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
1428 · install more documentation automatically, including man2html output
1429 · put dbus.devhelp in the right place (it must go in ${htmldir})
1432 · look for system services in /lib/dbus-1/system-services in addition to all
1433 the other well-known locations; note that this should always be /lib,
1434 even on platforms where shared libraries on the root FS would go in /lib64,
1435 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
1436 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
1438 • Windows-specific (Ralf Habacker):
1439 · fix use of a mutex for autolaunch server detection
1440 · don't crash on malloc failure in _dbus_printf_string_upper_bound
1442 D-Bus 1.5.4 (2011-06-10)
1445 Security (local denial of service):
1447 • Byte-swap foreign-endian messages correctly, preventing a long-standing
1448 local DoS if foreign-endian messages are relayed through the dbus-daemon
1449 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
1450 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
1454 • The constant to use for an infinite timeout now has a name,
1455 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
1456 which can be used for source compatibility with older versions of libdbus.
1458 • If GLib and DBus-GLib are already installed, more tests will be built,
1459 providing better coverage. The new tests can also be installed via
1460 ./configure --enable-installed-tests
1461 for system integration testing, if required. (fd.o #34570, Simon McVittie)
1465 • Consistently use atomic operations for the DBusConnection's refcount,
1466 fixing potential threading problems (fd.o #38005, Simon McVittie)
1468 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
1469 small (300KiB on x86-64) and it frequently doesn't work in unusual
1470 toolchains. To optimize for minimum installed size, you should benchmark
1471 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
1472 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
1474 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
1475 (fd.o #35880, Timothy Redaelli)
1477 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
1478 when not using a DESTDIR (fd.o #37870, Simon McVittie)
1480 • Windows-specific changes:
1481 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
1483 D-Bus 1.5.2 (2011-06-01)
1486 The "Boar Hunter" release.
1488 Notes for distributors:
1490 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
1491 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
1492 toolchain supports it reliably, via something like:
1494 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
1496 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
1500 • D-Bus Specification v0.17
1501 · Reserve the extra characters used in signatures by GVariant
1502 (fd.o #34529, Simon McVittie)
1503 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
1504 • Don't force -fPIE: distributions and libtool know better than we do whether
1505 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
1506 • Allow --disable-gc-sections, in case your toolchain offers the
1507 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
1508 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
1509 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
1510 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
1511 • Ensure that maintainers upload documentation with the right permissions
1512 (fd.o #36130, Simon McVittie)

1517 • Log messages dropped due to quotas to syslog (fd.o #35358,
1519 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
1520 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
1521 (fd.o #35228, Lennart Poettering)
1522 • In the regression tests, don't report fds as "leaked" if they were open
1523 on startup (fd.o #35173, Simon McVittie)
1524 • Make dbus-monitor bail out if asked to monitor more than one bus,
1525 rather than silently using the last one (fd.o #26548, Will Thompson)
1526 • Clarify documentation (fd.o #35182, Simon McVittie)
1527 • Clean up minor dead code and some incorrect error handling
1528 (fd.o #33128, fd.o #29881; Simon McVittie)
1529 • Check that compiler options are supported before using them (fd.o #19681,
1532 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
1534 D-Bus 1.5.0 (2011-04-11)
1537 The "you never know when you need to tow something from your giant
1538 flying shark" release.
1540 • D-Bus Specification v0.16
1541 · Add support for path_namespace and arg0namespace in match rules
1542 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
1543 · Make argNpath support object paths, not just object-path-like strings,
1544 and document it better (fd.o #31818, Will Thompson)
1545 • Let the bus daemon implement more than one interface (fd.o #33757,
1547 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
1549 • Require user intervention to compile with missing 64-bit support
1550 (fd.o #35114, Simon McVittie)
1551 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
1552 • Raise UnknownObject instead of UnknownMethod for calls to methods on
1553 paths that are not part of the object tree, and UnknownInterface for calls
1554 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)

1559 The "It's like the beginning of a lobster" release.
1561 • Rename configure.in to configure.ac, and update it to modern conventions
1562 (fd.o #32245; Javier Jardón, Simon McVittie)
1563 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
1565 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
1566 --disable-x11-autolaunch configure option to prevent it altogether
1567 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
1568 • Install the documentation, and an index for Devhelp (fd.o #13495,
1569 Debian #454142; Simon McVittie, Matthias Clasen)
1570 • If checks are not disabled, check validity of string-like types and
1571 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
1572 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
1573 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
1574 • Break up a huge conditional in config-parser so gcov can produce coverage
1575 data (fd.o #10887, Simon McVittie)
1576 • List which parts of the Desktop Entry specification are applicable to
1577 .service files (fd.o #19159, Sven Herzberg)
1578 • Don't suppress service activation if two services have the same Exec=

1589 The "1, 2, miss a few, 99, 100" release.
1591 • Remove unfinished changes intended to support GTest-based tests,
1592 which were mistakenly included in 1.4.4
1594 D-Bus 1.4.4 (2010-02-17)
1597 • Switch back to using even micro versions for stable releases; 1.4.1
1598 should have been called 1.4.2, so skip that version number
1599 • Don't leave bad file descriptors being watched when spawning processes,
1600 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
1601 also LP#656134, LP#680444, LP#713157)
1602 • Check for MSG_NOSIGNAL correctly
1603 • Fix failure to detect abstract socket support (fd.o #29895)
1604 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
1605 (fd.o #32262, NB#180486)
1606 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,

1635 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
1636 crash the bus. The existing restriction to 64-levels of nesting previously
1637 only applied to the static type signature; now it also applies to dynamic
1638 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
1640 • OS X portability fixes, including launchd support.
