1 D-Bus 1.8.8 (UNRELEASED)
6 D-Bus 1.8.6 (2014-06-02)
11 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
12 the message. This prevents an attack in which a malicious client can
13 make dbus-daemon disconnect a system service, which is a local
15 (fd.o #80163, CVE-2014-3532; Alban Crequy)
17 • Track remaining Unix file descriptors correctly when more than one
18 message in quick succession contains fds. This prevents another attack
19 in which a malicious client can make dbus-daemon disconnect a system
21 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
22 Simon McVittie, Alban Crequy)
26 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
27 attach to a session, kill the dbus-daemon as intended
28 (fd.o #74698, Роман Донченко)
30 D-Bus 1.8.4 (2014-06-10)
35 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
36 flaw in dbus-daemon, part of the reference implementation of D-Bus.
37 Additionally, in highly unusual environments the same flaw could lead to
38 a side channel between processes that should not be able to communicate.
39 (CVE-2014-3477, fd.o #78979)
41 D-Bus 1.8.2 (2014-04-30)
44 The “nobody wants red” release.
48 • in the CMake build system, add some hints for Linux users cross-compiling
49 Windows D-Bus binaries to be able to run tests under Wine
50 (fd.o #41252, Ralf Habacker)
52 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
56 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
57 to /var/lib/dbus/machine-id instead of generating an entirely new ID
58 (fd.o #77941, Simon McVittie)
60 • if dbus-launch receives an X error very quickly, do not kill
61 unrelated processes (fd.o #74698, Роман Донченко)
63 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
64 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
66 • cope with \r\n newlines in regression tests, since on Windows,
67 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
69 D-Bus 1.8.0 (2014-01-20)
72 The “Wolverine distrusts my printer” release.
74 This starts a new stable branch. The 1.6.x branch is now considered to be
75 outdated, and will only receive fixes for serious bugs such as security
76 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
77 are unlikely to get any more releases, but if distributors still need to
78 support them, please share security patches via upstream.
80 Summary of changes since 1.6.x:
82 • libdbus always behaves as if dbus_threads_init_default() had been called
83 (thread-safety by default)
84 • new dbus-run-session tool, replacing certain misuses of dbus-launch
85 • dbus-monitor can talk to outdated versions of dbus-daemon again
86 • new org.freedesktop.DBus.GetConnectionCredentials method
87 • GetConnectionUnixProcessID also works correctly on Windows, returning
88 the Windows process ID
89 • GetConnectionWindowsSID returns the correct SID on Windows
90 • expat is required, libxml2 can no longer be used as a substitute
91 • the userDB cache is required, and cannot be disabled
92 • a 64-bit integer type (either int, long, long long or _int64) is required
93 • better systemd-journald integration on Linux
94 • fixed long-standing fd and array leaks when failing to parse a message
95 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
96 when using certain object-path allocation patterns, notably in Avahi
97 • better defaults for Windows support
98 • better CMake support
99 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
100 • the source language for the man pages is now Docbook XML
102 Enhancements since 1.7.10:
104 • Enhance the CMake build system to check for GLib and compile/run
105 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
109 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
112 • fix compilation of systemd journal support on older systemd versions where
113 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
115 • fix compilation on older MSVC versions by including stdlib.h
116 (fd.o #73455, Ralf Habacker)
118 • Allow <allow_anonymous/> to appear in an included configuration file
119 (fd.o #73475, Matt Hoosier)
121 Test behaviour changes since 1.7.10:
123 • If the tests crash with an assertion failure, they no longer default to
124 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
125 environment if you want the old behaviour.
127 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
128 can be run with an external dbus-daemon by setting
129 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
130 an unusually-configured dbus-daemon are skipped.
132 D-Bus 1.7.10 (2014-01-06)
135 The “weighted companion cube” release.
137 This is a release candidate for D-Bus 1.8.
139 D-Bus Specification 0.23:
141 • don't require messages with no INTERFACE to be dispatched
142 (fd.o #68597, Simon McVittie)
144 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
147 • define "listenable" and "connectable" addresses, and discuss
148 the difference (fd.o #61303, Simon McVittie)
152 • support printing Unix file descriptors in dbus-send, dbus-monitor
153 (fd.o #70592, Robert Ancell)
155 • don't install systemd units if --disable-systemd is given
156 (fd.o #71818, Chengwei Yang)
160 • don't leak memory on out-of-memory while listing activatable or
161 active services (fd.o #71526, Radoslaw Pajak)
163 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
165 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
167 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
168 and DBUS__SEND_MSG are numerically equal to their values in the
169 reference policy (fd.o #88719, osmond sun)
171 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
172 (fd.o #71366, Matt Fischer)
174 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
175 winsock2.h (fd.o #71405, Matt Fischer)
177 • do not return failure from _dbus_read_nonce() with no error set,
178 preventing a potential crash (fd.o #72298, Chengwei Yang)
180 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
181 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
183 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
184 which doesn't do anything anyway on at least Linux and FreeBSD
185 (fd.o #69492, Simon McVittie)
187 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
188 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
189 for credentials more correctly (fd.o #69492, Simon McVittie)
191 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
192 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
195 • refresh cached policy rules for existing connections when bus
196 configuration changes (fd.o #39463, Chengwei Yang)
198 D-Bus 1.7.8 (2013-11-01)
201 The “extreme hills” release.
205 • If systemd support is enabled, libsystemd-journal is now required.
209 • When activating a non-systemd service under systemd, annotate its
210 stdout/stderr with its bus name in the Journal. Known limitation:
211 because the socket is opened before forking, the process will still be
212 logged as if it had dbus-daemon's process ID and user ID.
213 (fd.o #68559, Chengwei Yang)
215 • Document more configuration elements in dbus-daemon(1)
216 (fd.o #69125, Chengwei Yang)
220 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
221 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
223 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
224 disallowed method calls to the audit log, fixing a regression in 1.7.6
225 (fd.o #49062, Colin Walters)
227 • path_namespace='/' in match rules incorrectly matched nothing; it
228 now matches everything. (fd.o #70799, Simon McVittie)
230 D-Bus 1.7.6 (2013-10-09)
233 The “CSI Shrewsbury” release.
235 Build-time configuration changes:
237 • Directory change notification via dnotify on Linux is no longer
238 supported; it hadn't compiled successfully since 2010 in any case.
239 If you don't have inotify (Linux) or kqueue (*BSD), you will need
240 to send SIGHUP to the dbus-daemon when its configuration changes.
241 (fd.o #33001, Chengwei Yang)
243 • Compiling with --disable-userdb-cache is no longer supported;
244 it didn't work since at least 2008, and would lead to an extremely
245 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
248 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
249 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
250 with the Autotools build system. (fd.o #66142, Chengwei Yang)
252 • --with-valgrind=auto enables Valgrind instrumentation if and only if
253 valgrind headers are available. The default is still --with-valgrind=no.
254 (fd.o #56925, Simon McVittie)
258 • Platforms with no 64-bit integer type are no longer supported.
259 (fd.o #65429, Simon McVittie)
261 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
263 • Full test coverage no longer requires dbus-glib, although the tests do not
264 exercise the shared library (only a static copy) if dbus-glib is missing.
265 (fd.o #68852, Simon McVittie)
269 • D-Bus Specification 0.22
270 · Document GetAdtAuditSessionData() and
271 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
272 · Fix example .service file (fd.o #66481, Chengwei Yang)
273 · Don't claim D-Bus is "low-latency" (lower than what?), just
274 give factual statements about it supporting async use
275 (fd.o #65141, Justin Lee)
276 · Document the contents of .service files, and the fact that
277 system services' filenames are constrained
278 (fd.o #66608; Simon McVittie, Chengwei Yang)
280 • Be thread-safe by default on all platforms, even if
281 dbus_threads_init_default() has not been called. For compatibility with
282 older libdbus, library users should continue to call
283 dbus_threads_init_default(): it is harmless to do so.
284 (fd.o #54972, Simon McVittie)
286 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
288 • New API: dbus_setenv(), a simple wrapper around setenv().
289 Note that this is not thread-safe. (fd.o #39196, Simon)
291 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
292 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
293 (connect to a given bus, like dbus-monitor --address=ADDRESS).
294 dbus-send --address still exists for backwards compatibility,
295 but is no longer documented. (fd.o #48816, Andrey Mazo)
298 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
303 • Avoid an infinite busy-loop if a signal interrupts waitpid()
304 (fd.o #68945, Simon McVittie)
306 • Clean up memory for parent nodes when objects are unexported
307 (fd.o #60176, Thomas Fitzsimmons)
309 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
310 documented. Previously, it assumed its second parameter was TRUE.
311 (fd.o #69165, Chengwei Yang)
313 • Escape addresses containing non-ASCII characters correctly
314 (fd.o #53499, Chengwei Yang)
316 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
318 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
319 (fd.o #65923, Chengwei Yang)
321 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
322 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
324 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
325 that was never va_start()ed (fd.o #66300, Chengwei Yang)
327 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
329 • fix a regression test on platforms with strict alignment (fd.o #67279,
332 • Avoid calling function parameters "interface" since certain Windows headers
333 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
335 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
337 • Various thread-safety improvements to static variables (fd.o #68610,
340 • Make "make -j check" work (fd.o #68852, Simon McVittie)
342 • Fix a NULL pointer dereference on an unlikely error path
343 (fd.o #69327, Sviatoslav Chagaev)
345 • Improve valgrind memory pool tracking (fd.o #69326,
348 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
351 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
352 (fd.o #66107, Chengwei Yang)
355 · If accept4() fails with EINVAL, as it can on older Linux kernels
356 with newer glibc, try accept() instead of going into a busy-loop.
357 (fd.o #69026, Chengwei Yang)
358 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
359 for instance on Hurd or older Linux with a new glibc, try without
360 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)
361 · Fix a file descriptor leak on an error code path.
362 (fd.o #69182, Sviatoslav Chagaev)
363 · dbus-run-session: clear some unwanted environment variables
365 · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang)
366 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
367 · Use dbus-launch from the builddir for testing, not the installed copy
368 (fd.o #37849, Chengwei Yang)
369 · Fix compilation if writev() is unavailable (fd.o #69409,
371 · Remove broken support for LOCAL_CREDS credentials passing, and
372 document where each credential-passing scheme is used (fd.o #60340,
374 · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality
375 (fd.o #35881, #69787; Chengwei Yang)
376 · dbus-monitor: be portable to NetBSD (fd.o #69842, Chengwei Yang)
377 · dbus-launch: stop using non-portable asprintf (fd.o #37849, Simon)
378 · Improve error reporting from the setuid activation helper (fd.o #66728,
382 · Remove unavailable command-line options from 'dbus-daemon --help'
383 (fd.o #42441, Ralf Habacker)
384 · Add support for looking up local TCPv4 clients' credentials on
385 Windows XP via the undocumented AllocateAndGetTcpExTableFromStack
386 function (fd.o #66060, Ralf Habacker)
387 · Fix insufficient dependency-tracking (fd.o #68505, Simon McVittie)
388 · Don't include wspiapi.h, fixing a compiler warning (fd.o #68852,
392 · add DBUS_ENABLE_ASSERT, DBUS_ENABLE_CHECKS for less confusing
393 conditionals (fd.o #66142, Chengwei Yang)

395 · consolidate Autotools and CMake build (fd.o #64875, Ralf Habacker)
396 · fix various unused variables, unusual build configurations
397 etc. (fd.o #65712, #65990, #66005, #66257, #69165, #69410, #70218;
398 Chengwei Yang, Vasiliy Balyasnyy)
400 D-Bus 1.7.4 (2013-06-13)
403 The “but is your thread-safety thread-safe?” release.
407 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
408 of service for system services. Vulnerability reported by Alexandru Cornea.
413 • The Windows version of libdbus now contains a C++ source file, used
414 to provide global initialization when the library is loaded.
415 gcc (mingw*) users should ensure that g++ is also installed.
417 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
418 and was never the recommended option) has been removed. Expat is now a
423 • It should now be safe to call dbus_threads_init_default() from any thread,
424 at any time. Authors of loadable modules and plugins that use libdbus
425 should consider doing so during initialization.
426 (fd.o #54972, Simon McVittie)
428 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
432 · dbus-run-session: experimental new tool to start a temporary D-Bus
433 session, e.g. for regression tests or a text console, replacing
434 certain uses of dbus-launch which weren't really correct
439 • In dbus-daemon, don't crash if a .service file starts with key=value
440 (fd.o #60853, Chengwei Yang)
443 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
444 on a platform not defining LOG_PERROR, such as Solaris or QNX.
445 This regressed in 1.7.0. (Simon)
446 · Fix an assertion failure if we try to activate systemd services before
447 systemd connects to the bus (fd.o #50199, Chengwei Yang)
448 · Avoid compiler warnings for ignoring the return from write()
452 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
453 so that Windows finds them (fd.o #59733, Ralf Habacker)
455 D-Bus 1.7.2 (2013-04-25)
458 The “only partially opaque” release.
460 Configuration changes:
462 • On non-QNX Unix platforms, the default limit on fds per message in the
463 session bus configuration has reduced from 4096 to 1024. The default
464 limit used on the system bus was already 1024. On QNX, both limits are
465 reduced further, to 128.
469 • D-Bus Specification 0.21
470 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
471 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
476 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
477 (i.e. before allocating the slot) rather than returning junk
478 (fd.o #63127, Dan Williams)
480 • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker,
484 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
485 · Under systemd, log to syslog only, not stderr, avoiding duplication
486 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
487 · Under systemd, remove unnecessary dependency on syslog.socket
488 (fd.o #63531, Cristian Rodríguez)
489 · Include alloca.h for alloca() if available, fixing compilation on
490 Solaris 10 (fd.o #63071, Dagobert Michelsen)
491 · Allow use of systemd-logind without the rest of systemd
492 (fd.o #62585, Martin Pitt)
493 · When built with CMake, link to librt and use the right path for
494 meinproc's XSLT stylesheets (fd.o #61637, Ralf Habacker)
495 · Reduce the default limit on number of fds per message to 128 under
496 QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer)
499 · Do not claim that all bus clients have the dbus-daemon's credentials;
500 pick up local TCPv4 clients' credentials (process ID and security
501 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,
504 D-Bus 1.7.0 (2013-02-22)
507 The "Disingenuous Assertions" release.
509 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
510 remains the recommended version for long-term-supported distributions
511 or the upcoming GNOME 3.8 release.
513 Build-time configuration changes:
515 • The --with-dbus-session-bus-default-address configure option is no longer
516 supported. Use the new --with-dbus-session-bus-connect-address and
517 --with-dbus-session-bus-listen-address options instead. On Windows, you
518 usually want them to have the same argument; on Unix, the defaults are
521 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
522 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
523 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
525 • cmake/cross-compile.sh has been removed. Instead, please use a
526 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
527 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
528 as documented in "info automake Cross-Compilation", and set
529 PKG_CONFIG_PATH appropriately.
533 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
534 • man2html is no longer used.
538 • D-Bus Specification 0.20
539 · actually say that /org/freedesktop/DBus is the object that
540 implements o.fd.DBus (fd.o #51865, Colin Walters)
541 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
542 · stop claiming that all basic types work just like INT32 (strings don't!)
544 • The "source code" for the man pages is now Docbook XML, eliminating
545 the outdated duplicate copies used when building with CMake.
546 (fd.o #59805; Ralf Habacker, Simon McVittie)
550 • In the activation helper, when compiled for tests, do not reset the system
551 bus address, fixing the regression tests. (fd.o #52202, Simon)
553 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
554 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
556 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,
559 • Under CMake, prefer xmlto over meinproc (fd.o #59733, Ralf Habacker)
561 • Stop duplicating CMake's own logic to find libexpat
562 (fd.o #59733, Ralf Habacker)
564 • Don't assume CMake host and build system are the same (fd.o #59733,
567 • Avoid deprecation warnings for GLib 2.35 (fd.o #59971, Simon McVittie)
570 · Check for functions in libpthread correctly, fixing compilation on
571 (at least) OpenBSD (fd.o #47239, Simon)
572 · Don't leak temporary fds pointing to /dev/null (fd.o #56927,
574 · Update sd-daemon.[ch] from systemd (fd.o #60681)
575 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
578 · The default session bus listening and connecting address is now
579 "autolaunch:", which makes D-Bus on Windows interoperate with itself
580 and GDBus "out of the box". Use the configure options and cmake variables
581 described above if you require a different autolaunch scope.

588 D-Bus 1.6.8 (2012-09-28)
591 The "Fix one thing, break another" release.
593 • Follow up to CVE-2012-3524: The additional hardening
594 work to use __secure_getenv() as a followup to bug #52202
595 broke certain configurations of gnome-keyring. Given
596 the difficulty of making this work without extensive
597 changes to gnome-keyring, use of __secure_getenv() is
600 D-Bus 1.6.6 (2012-09-28)
603 The "Clear the environment in your setuid binaries, please" release.
605 • CVE-2012-3524: Don't access environment variables (fd.o #52202)

653 D-Bus 1.6.0 (2012-06-05)
656 The “soul of this machine has improved” release.
658 This version starts a new stable branch of D-Bus: only bug fixes will
659 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
661 Summary of changes since 1.4.x:
664 · PTHREAD_MUTEX_RECURSIVE on Unix
665 · compiler support for 64-bit integers (int64_t or equivalent)
667 • D-Bus Specification v0.19
669 • New dbus-daemon features
670 · <allow own_prefix="com.example.Service"/> rules allow the service to
671 own names like com.example.Service.Instance3
672 · optional systemd integration when checking at_console policies
673 · --nopidfile option, mainly for use by systemd
674 · path_namespace and arg0namespace may appear in match rules

678 · functions to validate various string types (dbus_validate_path() etc.)
679 · dbus_type_is_valid()
680 · DBusBasicValue, a union of every basic type
683 · removed an unsafe reimplementation of recursive mutexes
684 · dbus-daemon no longer busy-loops if it has far too many file descriptors
685 · dbus-daemon.exe --print-address works on Windows
686 · all the other bug fixes from 1.4.20
688 • Other major implementation changes
689 · on Linux, dbus-daemon uses epoll if supported, for better scalability
690 · dbus_threads_init() ignores its argument and behaves like
691 dbus_threads_init_default() instead
692 · removed the per-connection link cache, improving dbus-daemon performance
695 · optional Valgrind instrumentation (--with-valgrind)
696 · optional Stats interface on the dbus-daemon (--enable-stats)
697 · optionally abort whenever malloc() fails (--enable-embedded-tests
698 and export DBUS_MALLOC_CANNOT_FAIL=1)
700 Changes since 1.5.12:
702 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
703 spec-compliance (fd.o #48580, David Zeuthen)
705 • Don't use install(1) within the source/build trees, fixing the build as
706 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
708 • Add missing commas in some tcp and nonce-tcp addresses, and remove
709 an unused duplicate copy of the nonce-tcp transport in Windows builds
710 (fd.o #45896, Simon McVittie)
712 D-Bus 1.5.12 (2012-03-27)
715 The “Big Book of Science” release.
717 • Add public API to validate various string types:
718 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
719 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
720 (fd.o #39549, Simon McVittie)
722 • Turn DBusBasicValue into public API so bindings don't need to invent their
723 own "union of everything" type (fd.o #11191, Simon McVittie)
725 • Enumerate data files included in the build rather than using find(1)
726 (fd.o #33840, Simon McVittie)
728 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
729 in dbus-daemon (fd.o #46273, Alban Crequy)
732 · make dbus-daemon.exe --print-address (and --print-pid) work again
733 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
734 · fix duplicate case value when compiling against mingw-w64
735 (fd.o #47321, Andoni Morales Alastruey)
737 D-Bus 1.5.10 (2012-02-21)
740 The "fire in Delerium" release.
742 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
743 and SUSv2) is now required.
745 • D-Bus Specification 0.19:
746 · Formally define unique connection names and well-known bus names,
747 and document best practices for interface, bus, member and error names,
748 and object paths (fd.o #37095, Simon McVittie)
749 · Document the search path for session and system services on Unix, and
750 where they should be installed by build systems (fd.o #21620, fd.o #35306;
752 · Document the systemd transport (fd.o #35232, Lennart Poettering)
754 • Make dbus_threads_init() use the same built-in threading implementation
755 as dbus_threads_init_default(); the user-specified primitives that it
756 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
758 • Allow all configured auth mechanisms, not just one (fd.o #45106,
761 • Improve cmake build system (Ralf Habacker):
762 · simplify XML parser dependencies (fd.o #41027)
763 · generate build timestamp (fd.o #41029)
764 · only create batch files on Windows
765 · fix option and cache syntax
766 · add help-options target
767 · share dbus-arch-deps.h.in with autotools rather than having our
768 own version (fd.o #41033)
770 • Build tests successfully with older GLib, as found in e.g. Debian 6
771 (fd.o #41219, Simon McVittie)
773 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
775 • Build documentation correctly if man2html doesn't support filenames on
776 its command-line (fd.o #43875, Jack Nagel)
778 • Improve test coverage. To get even more coverage, run the tests with
779 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
781 • Reduce the size of the shared library by moving functionality only used
782 by dbus-daemon, tests etc. into their internal library and deleting
783 unused code (fd.o #34976, #39759; Simon McVittie)
785 • Add dbus-daemon --nopidfile option, overriding the configuration, for
786 setups where the default configuration must include <pidfile/> to avoid
787 breaking traditional init, but the pid file is in fact unnecessary; use
788 it under systemd to improve startup time a bit (fd.o #45520,
791 • Optionally (if configured --with-valgrind) add instrumentation to debug
792 libdbus and associated tools more meaningfully under Valgrind
793 (fd.o #37286, Simon McVittie)
795 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
797 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
799 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
800 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
801 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
804 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
808 · Replace our broken reimplementation of recursive mutexes, which has
809 been broken since 2006, with an ordinary pthreads recursive mutex
810 (fd.o #43744; Sigmund Augdal, Simon McVittie)
811 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
812 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
813 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
814 · When running under systemd, use it instead of ConsoleKit to check
815 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
816 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
817 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
818 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
819 (fd.o #41218, Simon McVittie)
820 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
821 helper doesn't obey environment variables to avoid privilege escalation
822 attacks, so make the system bus follow the same rules
823 (fd.o #21620, Simon McVittie)
826 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
827 Jesper Dam, Ralf Habacker)
828 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
831 D-Bus 1.5.8 (2011-09-21)
834 The "cross-metering" release.
836 In addition to dead code removal and refactoring, this release contains all
837 of the bugfixes from 1.4.16.
839 • Clean up dead code, and make more warnings fatal in development builds
840 (fd.o #39231, fd.o #41012; Simon McVittie)
842 • If full test coverage is requested via --enable-tests, strictly require
843 Python, pygobject and dbus-python, which are required by some tests; if not,
844 and Python is missing, skip those tests rather than failing
845 (fd.o #37847, Simon McVittie)
847 • When using cmake, provide the same version-info API in the installed headers
848 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
850 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
852 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
854 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
857 • Fix duplicates in authors list (Ralf Habacker)
859 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
860 (fd.o #39879, Chris Mayo)
862 • Fix a small memory leak, and a failure to report errors, when updating
863 a service file entry for activation (fd.o #39230, Simon McVittie)
866 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
867 Brian Cameron, Simon McVittie)
868 · On systems that use libcap-ng but not systemd, drop supplemental groups
869 when switching to the daemon user (Red Hat #726953, Steve Grubb)
870 · Make the cmake build work again on GNU platforms (fd.o #29228,
872 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
873 like Solaris (fd.o #40313, Dagobert Michelsen)
874 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
875 (fd.o #40235, Simon McVittie)
876 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
877 (fd.o #39987, Simon McVittie)
878 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
879 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
882 · Fix compilation on MSVC, which doesn't understand "inline" with its
883 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
884 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
885 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
887 D-Bus 1.5.6 (2011-07-29)
890 The "weird, gravy-like aftertaste" release.
892 In addition to new features and refactoring, this release contains all of the
893 bugfixes from 1.4.14.
895 Potentially incompatible (Bustle and similar debugging tools will need
896 changes to work as intended):
898 • Do not allow match rules to "eavesdrop" (receive messages intended for a
899 different recipient) by mistake: eavesdroppers must now opt-in to this
900 behaviour by putting "eavesdrop='true'" in the match rule, which will
901 not have any practical effect on buses where eavesdropping is not allowed
902 (fd.o #37890, Cosimo Alfarano)
906 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
907 Cosimo Alfarano, Simon McVittie)
908 · add the "eavesdrop" keyword to match rules
909 · define eavesdropping, unicast messages and broadcast messages
910 · stop claiming that match rules are needed to match unicast messages to you
911 · promote the type system to be a top-level section
913 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
914 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
915 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
917 • Consistently use atomic operations on everything that is ever manipulated
918 via atomic ops, as was done for changes to DBusConnection's refcount in
919 1.4.12 (fd.o #38005, Simon McVittie)
921 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
924 • Make "make check" in a clean tree work, by not running tests until
925 test data has been set up (fd.o #34405, Simon McVittie)
927 • The dbus-daemon no longer busy-loops if it has a very large number of file
928 descriptors (fd.o #23194, Simon McVittie)
930 • Refactor message flow through dispatching to avoid locking violations if
931 the bus daemon's message limit is hit; remove the per-connection link cache,
932 which was meant to improve performance, but now reduces it (fd.o #34393,
935 • Some cmake fixes (Ralf Habacker)
937 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
938 Simon McVittie, Lennart Poettering)
940 • Stop storing two extra byte order indicators in each D-Bus message
941 (fd.o #38287, Simon McVittie)
943 • Add an optional Stats interface which can be used to get statistics from
944 a running dbus-daemon if enabled at configure time with --enable-stats
945 (fd.o #34040, Simon McVittie)
947 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
949 • Documentation (fd.o #36156, Simon McVittie):
950 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
951 · install more documentation automatically, including man2html output
952 · put dbus.devhelp in the right place (it must go in ${htmldir})
955 · look for system services in /lib/dbus-1/system-services in addition to all
956 the other well-known locations; note that this should always be /lib,
957 even on platforms where shared libraries on the root FS would go in /lib64,
958 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
959 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
961 • Windows-specific (Ralf Habacker):
962 · fix use of a mutex for autolaunch server detection
963 · don't crash on malloc failure in _dbus_printf_string_upper_bound
965 D-Bus 1.5.4 (2011-06-10)
968 Security (local denial of service):
970 • Byte-swap foreign-endian messages correctly, preventing a long-standing
971 local DoS if foreign-endian messages are relayed through the dbus-daemon
972 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
973 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
977 • The constant to use for an infinite timeout now has a name,
978 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
979 which can be used for source compatibility with older versions of libdbus.
981 • If GLib and DBus-GLib are already installed, more tests will be built,
982 providing better coverage. The new tests can also be installed via
983 ./configure --enable-installed-tests
984 for system integration testing, if required. (fd.o #34570, Simon McVittie)
988 • Consistently use atomic operations for the DBusConnection's refcount,
989 fixing potential threading problems (fd.o #38005, Simon McVittie)
991 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
992 small (300KiB on x86-64) and it frequently doesn't work in unusual
993 toolchains. To optimize for minimum installed size, you should benchmark
994 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
995 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
997 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
998 (fd.o #35880, Timothy Redaelli)
1000 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
1001 when not using a DESTDIR (fd.o #37870, Simon McVittie)
1003 • Windows-specific changes:
1004 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
1006 D-Bus 1.5.2 (2011-06-01)
1009 The "Boar Hunter" release.
1011 Notes for distributors:
1013 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
1014 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
1015 toolchain supports it reliably, via something like:
1017 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
1019 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
1023 • D-Bus Specification v0.17
1024 · Reserve the extra characters used in signatures by GVariant
1025 (fd.o #34529, Simon McVittie)
1026 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
1027 • Don't force -fPIE: distributions and libtool know better than we do whether
1028 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
1029 • Allow --disable-gc-sections, in case your toolchain offers the
1030 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
1031 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
1032 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
1033 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
1034 • Ensure that maintainers upload documentation with the right permissions
1035 (fd.o #36130, Simon McVittie)
1036 • Don't force users of libdbus to be linked against -lpthread, -lrt
1037 (fd.o #32827, Simon McVittie)
1038 • Log system-bus activation information to syslog (fd.o #35705,
1040 • Log messages dropped due to quotas to syslog (fd.o #35358,
1042 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
1043 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
1044 (fd.o #35228, Lennart Poettering)
1045 • In the regression tests, don't report fds as "leaked" if they were open
1046 on startup (fd.o #35173, Simon McVittie)
1047 • Make dbus-monitor bail out if asked to monitor more than one bus,
1048 rather than silently using the last one (fd.o #26548, Will Thompson)
1049 • Clarify documentation (fd.o #35182, Simon McVittie)
1050 • Clean up minor dead code and some incorrect error handling
1051 (fd.o #33128, fd.o #29881; Simon McVittie)
1052 • Check that compiler options are supported before using them (fd.o #19681,
1055 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
1057 D-Bus 1.5.0 (2011-04-11)
1060 The "you never know when you need to tow something from your giant
1061 flying shark" release.
1063 • D-Bus Specification v0.16
1064 · Add support for path_namespace and arg0namespace in match rules
1065 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
1066 · Make argNpath support object paths, not just object-path-like strings,
1067 and document it better (fd.o #31818, Will Thompson)
1068 • Let the bus daemon implement more than one interface (fd.o #33757,
1070 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
1072 • Require user intervention to compile with missing 64-bit support
1073 (fd.o #35114, Simon McVittie)
1074 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
1075 • Raise UnknownObject instead of UnknownMethod for calls to methods on
1076 paths that are not part of the object tree, and UnknownInterface for calls
1077 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
1079 D-Bus 1.4.8 (2011-04-08)
1082 The "It's like the beginning of a lobster" release.
1084 • Rename configure.in to configure.ac, and update it to modern conventions
1085 (fd.o #32245; Javier Jardón, Simon McVittie)
1086 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
1088 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
1089 --disable-x11-autolaunch configure option to prevent it altogether
1090 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
1091 • Install the documentation, and an index for Devhelp (fd.o #13495,
1092 Debian #454142; Simon McVittie, Matthias Clasen)
