1 D-Bus 1.7.6 (UNRELEASED)
4 Build-time configuration changes:
6 • Directory change notification via dnotify on Linux is no longer
7 supported; it hadn't compiled successfully since 2010 in any case.
8 If you don't have inotify (Linux) or kqueue (*BSD), you will need
9 to send SIGHUP to the dbus-daemon when its configuration changes.
10 (fd.o #33001, Chengwei Yang)
12 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
13 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
14 with the Autotools build system. (fd.o #66142, Chengwei Yang)
18 • Be thread-safe by default on all platforms, even if
19 dbus_threads_init_default() has not been called. For compatibility with
20 older libdbus, library users should continue to call
21 dbus_threads_init_default(): it is harmless to do so.
22 (fd.o #54972, Simon McVittie)
26 • Escape addresses containing non-ASCII characters correctly
27 (fd.o #53499, Chengwei Yang)
29 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
30 (fd.o #65923, Chengwei Yang)
32 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
33 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
35 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
36 that was never va_start()ed (fd.o #66300, Chengwei Yang)
38 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
40 • fix a regression test on platforms with strict alignment (fd.o #67279,
44 · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang)
47 · Remove unavailable command-line options from 'dbus-daemon --help'
48 (fd.o #42441, Ralf Habacker)
49 · Add support for looking up local TCPv4 clients' credentials on
50 Windows XP via the undocumented AllocateAndGetTcpExTableFromStack
51 function (fd.o #66060, Ralf Habacker)
54 · add DBUS_ENABLE_ASSERT, DBUS_ENABLE_CHECKS for less confusing
55 conditionals (fd.o #66142, Chengwei Yang)
56 · improve verbose-mode output (fd.o #63047, Colin Walters)
57 · consolidate Autotools and CMake build (fd.o #64875, Ralf Habacker)
58 · fix various unused variables, unusual build configurations
59 etc. (fd.o #65712, #65990, #66005, #66257; Chengwei Yang)
61 D-Bus 1.7.4 (2013-06-13)
64 The “but is your thread-safety thread-safe?” release.
68 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
69 of service for system services. Vulnerability reported by Alexandru Cornea.
74 • The Windows version of libdbus now contains a C++ source file, used
75 to provide global initialization when the library is loaded.
76 gcc (mingw*) users should ensure that g++ is also installed.
78 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
79 and was never the recommended option) has been removed. Expat is now a
84 • It should now be safe to call dbus_threads_init_default() from any thread,
85 at any time. Authors of loadable modules and plugins that use libdbus
86 should consider doing so during initialization.
87 (fd.o #54972, Simon McVittie)
89 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
94 • In dbus-daemon, don't crash if a .service file starts with key=value
95 (fd.o #60853, Chengwei Yang)
98 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
99 on a platform not defining LOG_PERROR, such as Solaris or QNX.
100 This regressed in 1.7.0. (Simon)
101 · Fix an assertion failure if we try to activate systemd services before
102 systemd connects to the bus (fd.o #50199, Chengwei Yang)
103 · Avoid compiler warnings for ignoring the return from write()
107 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
108 so that Windows finds them (fd.o #59733, Ralf Habacker)
110 D-Bus 1.7.2 (2013-04-25)
113 The “only partially opaque” release.
115 Configuration changes:
117 • On non-QNX Unix platforms, the default limit on fds per message in the
118 session bus configuration has reduced from 4096 to 1024. The default
119 limit used on the system bus was already 1024. On QNX, both limits are
120 reduced further, to 128.
124 • D-Bus Specification 0.21
125 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
126 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
131 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
132 (i.e. before allocating the slot) rather than returning junk
133 (fd.o #63127, Dan Williams)
135 • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker,
139 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
140 · Under systemd, log to syslog only, not stderr, avoiding duplication
141 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
142 · Under systemd, remove unnecessary dependency on syslog.socket
143 (fd.o #63531, Cristian Rodríguez)
144 · Include alloca.h for alloca() if available, fixing compilation on
145 Solaris 10 (fd.o #63071, Dagobert Michelsen)
146 · Allow use of systemd-logind without the rest of systemd
147 (fd.o #62585, Martin Pitt)
148 · When built with CMake, link to librt and use the right path for
149 meinproc's XSLT stylesheets (fd.o #61637, Ralf Habacker)
150 · Reduce the default limit on number of fds per message to 128 under
151 QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer)
154 · Do not claim that all bus clients have the dbus-daemon's credentials;
155 pick up local TCPv4 clients' credentials (process ID and security
156 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,
159 D-Bus 1.7.0 (2013-02-22)
162 The "Disingenuous Assertions" release.
164 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
165 remains the recommended version for long-term-supported distributions
166 or the upcoming GNOME 3.8 release.
168 Build-time configuration changes:
170 • The --with-dbus-session-bus-default-address configure option is no longer
171 supported. Use the new --with-dbus-session-bus-connect-address and
172 --with-dbus-session-bus-listen-address options instead. On Windows, you
173 usually want them to have the same argument; on Unix, the defaults are
176 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
177 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
178 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
180 • cmake/cross-compile.sh has been removed. Instead, please use a
181 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
182 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
183 as documented in "info automake Cross-Compilation", and set
184 PKG_CONFIG_PATH appropriately.
188 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
189 • man2html is no longer used.
193 • D-Bus Specification 0.20
194 · actually say that /org/freedesktop/DBus is the object that
195 implements o.fd.DBus (fd.o #51865, Colin Walters)
196 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
197 · stop claiming that all basic types work just like INT32 (strings don't!)
199 • The "source code" for the man pages is now Docbook XML, eliminating
200 the outdated duplicate copies used when building with CMake.
201 (fd.o #59805; Ralf Habacker, Simon McVittie)
205 • In the activation helper, when compiled for tests, do not reset the system
206 bus address, fixing the regression tests. (fd.o #52202, Simon)
208 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
209 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
211 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,
214 • Under CMake, prefer xmlto over meinproc (fd.o #59733, Ralf Habacker)
216 • Stop duplicating CMake's own logic to find libexpat
217 (fd.o #59733, Ralf Habacker)
219 • Don't assume CMake host and build system are the same (fd.o #59733,
222 • Avoid deprecation warnings for GLib 2.35 (fd.o #59971, Simon McVittie)
225 · Check for functions in libpthread correctly, fixing compilation on
226 (at least) OpenBSD (fd.o #47239, Simon)
227 · Don't leak temporary fds pointing to /dev/null (fd.o #56927,
229 · Update sd-daemon.[ch] from systemd (fd.o #60681)
230 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
233 · The default session bus listening and connecting address is now
234 "autolaunch:", which makes D-Bus on Windows interoperate with itself
235 and GDBus "out of the box". Use the configure options and cmake variables
236 described above if you require a different autolaunch scope.
237 (fd.o #38201, Simon McVittie)
238 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
240 • Create session.d, system.d directories under CMake (fd.o #41319,
243 D-Bus 1.6.8 (2012-09-28)
246 The "Fix one thing, break another" release.
248 • Follow up to CVE-2012-3524: The additional hardening
249 work to use __secure_getenv() as a followup to bug #52202
250 broke certain configurations of gnome-keyring. Given
251 the difficulty of making this work without extensive
252 changes to gnome-keyring, use of __secure_getenv() is
255 D-Bus 1.6.6 (2012-09-28)
258 The "Clear the environment in your setuid binaries, please" release.
260 • CVE-2012-3524: Don't access environment variables (fd.o #52202)
261 Thanks to work and input from Colin Walters, Simon McVittie,
262 Geoffrey Thomas, and others.
264 · Fix compilation on Solaris (fd.o #53286, Jonathan Perkin)
265 · Work around interdependent headers on OpenBSD by including sys/types.h
266 before each use of sys/socket.h (fd.o #54418, Brad Smith)
268 D-Bus 1.6.4 (2012-07-18)
271 • Detect that users are "at the console" correctly when configured with
272 a non-default path such as --enable-console-auth-dir=/run/console
273 (fd.o #51521, Dave Reisner)
275 • Remove an incorrect assertion from DBusTransport (fd.o #51657,
278 • Make --enable-developer default to "no" (regression in 1.6.2;
279 fd.o #51657, Simon McVittie)
282 · Launch dbus-daemon correctly if its path contains a space
283 (fd.o #49450, Wolfgang Baron)
285 D-Bus 1.6.2 (2012-06-27)
288 The "Ice Cabbage" release.
290 • Change how we create /var/lib/dbus so it works under Automake >= 1.11.4
291 (fd.o #51406, Simon McVittie)
293 • Don't return from dbus_pending_call_set_notify with a lock held on OOM
294 (fd.o #51032, Simon McVittie)
296 • Disconnect "developer mode" (assertions, verbose mode etc.) from
297 Automake maintainer mode. D-Bus developers should now configure with
298 --enable-developer. Automake maintainer mode is now on by default;
299 distributions can disable it with --disable-maintainer-mode.
300 (fd.o #34671, Simon McVittie)
302 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
303 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
306 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
308 D-Bus 1.6.0 (2012-06-05)
311 The “soul of this machine has improved” release.
313 This version starts a new stable branch of D-Bus: only bug fixes will
314 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
316 Summary of changes since 1.4.x:
319 · PTHREAD_MUTEX_RECURSIVE on Unix
320 · compiler support for 64-bit integers (int64_t or equivalent)
322 • D-Bus Specification v0.19

326 own names like com.example.Service.Instance3
327 · optional systemd integration when checking at_console policies
328 · --nopidfile option, mainly for use by systemd
329 · path_namespace and arg0namespace may appear in match rules

335 · DBusBasicValue, a union of every basic type
338 · removed an unsafe reimplementation of recursive mutexes
339 · dbus-daemon no longer busy-loops if it has far too many file descriptors
340 · dbus-daemon.exe --print-address works on Windows
341 · all the other bug fixes from 1.4.20
343 • Other major implementation changes
344 · on Linux, dbus-daemon uses epoll if supported, for better scalability
345 · dbus_threads_init() ignores its argument and behaves like
346 dbus_threads_init_default() instead
347 · removed the per-connection link cache, improving dbus-daemon performance
350 · optional Valgrind instrumentation (--with-valgrind)
351 · optional Stats interface on the dbus-daemon (--enable-stats)
352 · optionally abort whenever malloc() fails (--enable-embedded-tests
353 and export DBUS_MALLOC_CANNOT_FAIL=1)
355 Changes since 1.5.12:
357 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
358 spec-compliance (fd.o #48580, David Zeuthen)
360 • Don't use install(1) within the source/build trees, fixing the build as
361 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
363 • Add missing commas in some tcp and nonce-tcp addresses, and remove
364 an unused duplicate copy of the nonce-tcp transport in Windows builds
365 (fd.o #45896, Simon McVittie)
367 D-Bus 1.5.12 (2012-03-27)
370 The “Big Book of Science” release.
372 • Add public API to validate various string types:
373 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
374 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
375 (fd.o #39549, Simon McVittie)
377 • Turn DBusBasicValue into public API so bindings don't need to invent their
378 own "union of everything" type (fd.o #11191, Simon McVittie)
380 • Enumerate data files included in the build rather than using find(1)
381 (fd.o #33840, Simon McVittie)
383 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
384 in dbus-daemon (fd.o #46273, Alban Crequy)
387 · make dbus-daemon.exe --print-address (and --print-pid) work again
388 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
389 · fix duplicate case value when compiling against mingw-w64
390 (fd.o #47321, Andoni Morales Alastruey)
392 D-Bus 1.5.10 (2012-02-21)
395 The "fire in Delerium" release.
397 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
398 and SUSv2) is now required.
400 • D-Bus Specification 0.19:
401 · Formally define unique connection names and well-known bus names,
402 and document best practices for interface, bus, member and error names,
403 and object paths (fd.o #37095, Simon McVittie)
404 · Document the search path for session and system services on Unix, and
405 where they should be installed by build systems (fd.o #21620, fd.o #35306;
407 · Document the systemd transport (fd.o #35232, Lennart Poettering)
409 • Make dbus_threads_init() use the same built-in threading implementation
410 as dbus_threads_init_default(); the user-specified primitives that it
411 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
413 • Allow all configured auth mechanisms, not just one (fd.o #45106,
416 • Improve cmake build system (Ralf Habacker):
417 · simplify XML parser dependencies (fd.o #41027)
418 · generate build timestamp (fd.o #41029)
419 · only create batch files on Windows
420 · fix option and cache syntax
421 · add help-options target
422 · share dbus-arch-deps.h.in with autotools rather than having our
423 own version (fd.o #41033)
425 • Build tests successfully with older GLib, as found in e.g. Debian 6
426 (fd.o #41219, Simon McVittie)
428 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
430 • Build documentation correctly if man2html doesn't support filenames on
431 its command-line (fd.o #43875, Jack Nagel)
433 • Improve test coverage. To get even more coverage, run the tests with
434 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
436 • Reduce the size of the shared library by moving functionality only used
437 by dbus-daemon, tests etc. into their internal library and deleting
438 unused code (fd.o #34976, #39759; Simon McVittie)
440 • Add dbus-daemon --nopidfile option, overriding the configuration, for
441 setups where the default configuration must include <pidfile/> to avoid
442 breaking traditional init, but the pid file is in fact unnecessary; use
443 it under systemd to improve startup time a bit (fd.o #45520,
446 • Optionally (if configured --with-valgrind) add instrumentation to debug
447 libdbus and associated tools more meaningfully under Valgrind
448 (fd.o #37286, Simon McVittie)
450 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
452 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
454 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
455 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
456 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
459 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
463 · Replace our broken reimplementation of recursive mutexes, which has
464 been broken since 2006, with an ordinary pthreads recursive mutex
465 (fd.o #43744; Sigmund Augdal, Simon McVittie)
466 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
467 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
468 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
469 · When running under systemd, use it instead of ConsoleKit to check
470 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
471 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
472 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
473 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
474 (fd.o #41218, Simon McVittie)
475 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
476 helper doesn't obey environment variables to avoid privilege escalation
477 attacks, so make the system bus follow the same rules
478 (fd.o #21620, Simon McVittie)
481 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
482 Jesper Dam, Ralf Habacker)
483 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
486 D-Bus 1.5.8 (2011-09-21)
489 The "cross-metering" release.
491 In addition to dead code removal and refactoring, this release contains all
492 of the bugfixes from 1.4.16.
494 • Clean up dead code, and make more warnings fatal in development builds
495 (fd.o #39231, fd.o #41012; Simon McVittie)
497 • If full test coverage is requested via --enable-tests, strictly require
498 Python, pygobject and dbus-python, which are required by some tests; if not,
499 and Python is missing, skip those tests rather than failing
500 (fd.o #37847, Simon McVittie)
502 • When using cmake, provide the same version-info API in the installed headers
503 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
505 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
507 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
509 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
512 • Fix duplicates in authors list (Ralf Habacker)
514 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
515 (fd.o #39879, Chris Mayo)
517 • Fix a small memory leak, and a failure to report errors, when updating
518 a service file entry for activation (fd.o #39230, Simon McVittie)
521 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
522 Brian Cameron, Simon McVittie)
523 · On systems that use libcap-ng but not systemd, drop supplemental groups
524 when switching to the daemon user (Red Hat #726953, Steve Grubb)
525 · Make the cmake build work again on GNU platforms (fd.o #29228,
527 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
528 like Solaris (fd.o #40313, Dagobert Michelsen)
529 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
530 (fd.o #40235, Simon McVittie)
531 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
532 (fd.o #39987, Simon McVittie)
533 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
534 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
537 · Fix compilation on MSVC, which doesn't understand "inline" with its
538 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
539 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
540 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
542 D-Bus 1.5.6 (2011-07-29)
545 The "weird, gravy-like aftertaste" release.
547 In addition to new features and refactoring, this release contains all of the
548 bugfixes from 1.4.14.
550 Potentially incompatible (Bustle and similar debugging tools will need
551 changes to work as intended):
553 • Do not allow match rules to "eavesdrop" (receive messages intended for a
554 different recipient) by mistake: eavesdroppers must now opt-in to this
555 behaviour by putting "eavesdrop='true'" in the match rule, which will
556 not have any practical effect on buses where eavesdropping is not allowed
557 (fd.o #37890, Cosimo Alfarano)
561 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
562 Cosimo Alfarano, Simon McVittie)
563 · add the "eavesdrop" keyword to match rules
564 · define eavesdropping, unicast messages and broadcast messages
565 · stop claiming that match rules are needed to match unicast messages to you
566 · promote the type system to be a top-level section
568 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
569 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
570 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
572 • Consistently use atomic operations on everything that is ever manipulated
573 via atomic ops, as was done for changes to DBusConnection's refcount in
574 1.4.12 (fd.o #38005, Simon McVittie)
576 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
579 • Make "make check" in a clean tree work, by not running tests until
580 test data has been set up (fd.o #34405, Simon McVittie)
582 • The dbus-daemon no longer busy-loops if it has a very large number of file
583 descriptors (fd.o #23194, Simon McVittie)
585 • Refactor message flow through dispatching to avoid locking violations if
586 the bus daemon's message limit is hit; remove the per-connection link cache,
587 which was meant to improve performance, but now reduces it (fd.o #34393,
590 • Some cmake fixes (Ralf Habacker)
592 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
593 Simon McVittie, Lennart Poettering)
595 • Stop storing two extra byte order indicators in each D-Bus message
596 (fd.o #38287, Simon McVittie)
598 • Add an optional Stats interface which can be used to get statistics from
599 a running dbus-daemon if enabled at configure time with --enable-stats
600 (fd.o #34040, Simon McVittie)
602 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
604 • Documentation (fd.o #36156, Simon McVittie):
605 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
606 · install more documentation automatically, including man2html output
607 · put dbus.devhelp in the right place (it must go in ${htmldir})
610 · look for system services in /lib/dbus-1/system-services in addition to all
611 the other well-known locations; note that this should always be /lib,
612 even on platforms where shared libraries on the root FS would go in /lib64,
613 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
614 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
616 • Windows-specific (Ralf Habacker):
617 · fix use of a mutex for autolaunch server detection
618 · don't crash on malloc failure in _dbus_printf_string_upper_bound
620 D-Bus 1.5.4 (2011-06-10)
623 Security (local denial of service):
625 • Byte-swap foreign-endian messages correctly, preventing a long-standing
626 local DoS if foreign-endian messages are relayed through the dbus-daemon
627 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
628 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
632 • The constant to use for an infinite timeout now has a name,
633 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
634 which can be used for source compatibility with older versions of libdbus.
636 • If GLib and DBus-GLib are already installed, more tests will be built,
637 providing better coverage. The new tests can also be installed via
638 ./configure --enable-installed-tests
639 for system integration testing, if required. (fd.o #34570, Simon McVittie)
643 • Consistently use atomic operations for the DBusConnection's refcount,
644 fixing potential threading problems (fd.o #38005, Simon McVittie)
646 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
647 small (300KiB on x86-64) and it frequently doesn't work in unusual
648 toolchains. To optimize for minimum installed size, you should benchmark
649 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
650 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
652 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
653 (fd.o #35880, Timothy Redaelli)
655 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
656 when not using a DESTDIR (fd.o #37870, Simon McVittie)
658 • Windows-specific changes:
659 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
661 D-Bus 1.5.2 (2011-06-01)
664 The "Boar Hunter" release.
666 Notes for distributors:
668 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
669 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
670 toolchain supports it reliably, via something like:
672 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
674 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
678 • D-Bus Specification v0.17

683 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
684 • Allow --disable-gc-sections, in case your toolchain offers the
685 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
686 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
687 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
688 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
689 • Ensure that maintainers upload documentation with the right permissions
690 (fd.o #36130, Simon McVittie)
691 • Don't force users of libdbus to be linked against -lpthread, -lrt
692 (fd.o #32827, Simon McVittie)
693 • Log system-bus activation information to syslog (fd.o #35705,
695 • Log messages dropped due to quotas to syslog (fd.o #35358,
697 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
698 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
699 (fd.o #35228, Lennart Poettering)
700 • In the regression tests, don't report fds as "leaked" if they were open
701 on startup (fd.o #35173, Simon McVittie)
702 • Make dbus-monitor bail out if asked to monitor more than one bus,

720 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
721 · Make argNpath support object paths, not just object-path-like strings,
722 and document it better (fd.o #31818, Will Thompson)
723 • Let the bus daemon implement more than one interface (fd.o #33757,
725 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
727 • Require user intervention to compile with missing 64-bit support
728 (fd.o #35114, Simon McVittie)
729 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
730 • Raise UnknownObject instead of UnknownMethod for calls to methods on
731 paths that are not part of the object tree, and UnknownInterface for calls
732 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
734 D-Bus 1.4.8 (2011-04-08)
737 The "It's like the beginning of a lobster" release.
739 • Rename configure.in to configure.ac, and update it to modern conventions
740 (fd.o #32245; Javier Jardón, Simon McVittie)
741 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
743 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
744 --disable-x11-autolaunch configure option to prevent it altogether
745 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
746 • Install the documentation, and an index for Devhelp (fd.o #13495,
747 Debian #454142; Simon McVittie, Matthias Clasen)
748 • If checks are not disabled, check validity of string-like types and
749 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
750 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
751 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
752 • Break up a huge conditional in config-parser so gcov can produce coverage
753 data (fd.o #10887, Simon McVittie)
754 • List which parts of the Desktop Entry specification are applicable to
755 .service files (fd.o #19159, Sven Herzberg)
756 • Don't suppress service activation if two services have the same Exec=
757 (fd.o #35750, Colin Walters)
759 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
761 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
762 (fd.o #32805, Mark Brand)

770 which were mistakenly included in 1.4.4
772 D-Bus 1.4.4 (2010-02-17)
775 • Switch back to using even micro versions for stable releases; 1.4.1
776 should have been called 1.4.2, so skip that version number
777 • Don't leave bad file descriptors being watched when spawning processes,
778 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
779 also LP#656134, LP#680444, LP#713157)
780 • Check for MSG_NOSIGNAL correctly
781 • Fix failure to detect abstract socket support (fd.o #29895)

810 D-Bus 1.4.1 (20 December 2010)
813 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
814 crash the bus. The existing restriction to 64-levels of nesting previously
815 only applied to the static type signature; now it also applies to dynamic
816 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
818 • OS X portability fixes, including launchd support.
819 • Windows autolaunch improvements.
