D-Bus 1.10.24 (2017-09-25) == The “pirate wizard” release. Fixes: • When parsing dbus-daemon configuration, tell Expat not to use cryptographic-quality entropy as a salt for its hash tables: we trust the configuration files, so we are not concerned about algorithmic complexity attacks via hash table collisions. This prevents dbus-daemon --system from holding up the boot process (and causing early-boot system services like systemd, logind, networkd to time out) on entropy-starved embedded systems. (fd.o #101858, Simon McVittie) • Increase listen() backlog of AF_UNIX sockets to the maximum possible, minimizing failed connections under heavy load (fd.o #95264, Lennart Poettering) (backported from 1.11.4) • Avoid a -Werror=declaration-after-statement build failure on Solaris (fd.o #102145, Alan Coopersmith) • When using the Monitoring interface, match messages' destinations (fd.o #92074, Simon McVittie) (backported from 1.11.0) D-Bus 1.10.22 (2017-07-27) == The “roof terrace” release. Fixes: • dbus_message_iter_append_basic() no longer leaks memory if it fails to append a file descriptor to a message. (fd.o #101568, Simon McVittie) • dbus_message_iter_open_container() no longer leaks memory if it runs out of memory. (fd.o #101568, Simon McVittie) • dbus_message_append_args_valist() no longer leaks memory if given an unsupported type. This situation is still considered to be a programming error which needs to be corrected by the user of libdbus. (fd.o #101568, Simon McVittie) • Wrap test-pending-call-disconnected with dbus-run-session so that it can pass in environments that are not already running a D-Bus session bus, fixing a build-time test regression in 1.10.20 (fd.o #101698, Simon McVittie) • Ensure that tests fail if they would otherwise have tried to connect to the real session bus (fd.o #101698, Simon McVittie) • Make build-time tests cope with finding Python 3, but not Python 2 (fd.o #101716, Simon McVittie) D-Bus 1.10.20 (2017-06-29) == The “suggesting a delivery gone horribly wrong” release. Fixes: • Fix a reference leak when blocking on a pending call on a connection that has been disconnected (fd.o #101481, Shin-ichi MORITA) • Don't put timestamps in the Doxygen-generated documentation, for closer-to-reproducible builds (fd.o #100692, Simon McVittie) • Avoid an assertion failure when connecting to a semicolon-separated series of addresses, one of which fails (fd.o #101257, Simon McVittie) Documentation: • Update git URIs in HACKING document to sync up with cgit.freedesktop.org (fd.o #100715, Simon McVittie) D-Bus 1.10.18 (2017-04-05) == The “can't handle a self-referential paradox” release. Fixes: • Re-order dbus-daemon startup so that on SELinux systems, the thread that reads AVC notifications retains the ability to write to the audit log (fd.o #92832, Debian #857660; Laurent Bigonville) • Fix a harmless read overflow and some memory leaks in a unit test (fd.o #100568, Philip Withnall) D-Bus 1.10.16 (2017-02-16) == The “super digging powers” release. The fixes in this release are arguably security fixes, but if they affect you, please take this opportunity to rethink how you are configuring dbus. Enhancements: • Do the Travis-CI build in Docker containers for Ubuntu LTS, Debian stable and Debian testing in addition to the older Ubuntu that is the default (fd.o #98889, Simon McVittie) Fixes: • Prevent symlink attacks in the nonce-tcp transport on Unix that could allow an attacker to overwrite a file named "nonce", in a directory that the user running dbus-daemon can write, with a random value known only to the user running dbus-daemon. This is unlikely to be exploitable in practice, particularly since the nonce-tcp transport is really only useful on Windows. On Unix systems we strongly recommend using only the unix: and systemd: transports, together with EXTERNAL authentication. These are the only transports and authentication mechanisms enabled by default. (fd.o #99828, Simon McVittie) • Avoid symlink attacks in the "embedded tests", which are not enabled by default and should never be enabled in production builds of dbus. (fd.o #99828, Simon McVittie) D-Bus 1.10.14 (2016-11-28) == The “Well, other bands know more than three chords” release. Fixes: • Work around an undesired effect of the fix for CVE-2014-3637 (fd.o #80559), in which processes that frequently send fds, such as logind during a flood of new PAM sessions, can get disconnected for continuously having at least one fd "in flight" for too long; dbus-daemon interprets that as a potential denial of service attack. The workaround is to disable that check for uid 0 process such as logind, with a message in the system log. The bug remains open while we look for a more general solution. (fd.o #95263, LP#1591411; Simon McVittie) • Don't run the test test-dbus-launch-x11.sh if X11 autolaunching was disabled at compile time. That test is not expected to work in that configuration. (fd.o #98665, Simon McVittie) D-Bus 1.10.12 (2016-10-10) == The “not excessively inhospitable” release. Security fixes: • Do not treat ActivationFailure message received from root-owned systemd name as a format string. In principle this is a security vulnerability, but we do not believe it is exploitable in practice, because only privileged processes can own the org.freedesktop.systemd1 bus name, and systemd does not appear to send activation failures that contain "%". Please note that this probably *was* exploitable in dbus versions older than 1.6.30, 1.8.16 and 1.9.10 due to a missing check which at the time was only thought to be a denial of service vulnerability (CVE-2015-0245). If you are still running one of those versions, patch or upgrade immediately. (fd.o #98157, Simon McVittie) Other fixes: • Harden dbus-daemon against malicious or incorrect ActivationFailure messages by rejecting them if they do not come from a privileged process, or if systemd activation is not enabled (fd.o #98157, Simon McVittie) • Avoid undefined behaviour when setting reply serial number without going via union DBusBasicValue (fd.o #98035, Marc Mutz) • autogen.sh: fail cleanly if autoconf fails (Simon McVittie) D-Bus 1.10.10 (2016-08-15) == The “tungsten door” release. Fixes: • On Linux, when dbus-daemon is run with reduced susceptibility to the OOM killer (typically via systemd), do not let child processes inherit that setting (fd.o #32851; Kimmo Hämäläinen, WaLyong Cho) • Output valid shell syntax in ~/.dbus/session-bus/ if the bus address contains a semicolon (fd.o #94746, Thiago Macieira) • Fix memory leaks and thread safety in subprocess starting on Windows (fd.o #95191, Ralf Habacker) • Do not require systemd to have a service file if using it for activation (fd.o #93194; Simon McVittie; backport from 1.11.0) • Stop test-dbus-daemon incorrectly failing on platforms that cannot discover the process ID of clients (fd.o #96653, Руслан Ижбулатов) • In tests that exercise correct handling of crashing D-Bus services, suppress Windows crash handler (fd.o #95155; Yiyang Fei, Ralf Habacker) • Explicitly check for stdint.h (Ioan-Adrian Ratiu) • update-activation-environment: produce better diagnostics on error (fd.o #96653, Simon McVittie) • Don't fail the build with an unused const variable warning under gcc 6 (fd.o #97282; Thomas Zimmermann, Simon McVittie) • Merge dbus-1.10-ci branch, containing backports from 1.11.0 in build/test code to support continuous integration (fd.o #93194, Simon McVittie) · Avoid -Wunused-label when compiling with libselinux but no libaudit · In development builds, allow OOM tests to be disabled as documented · Accept and ignore the --tap argument in all "embedded tests", and run all automated tests with that argument for better diagnostics · Fix the systemd activation test under CMake by installing the required files · In Automake, fix shell syntax for installcheck-local with no DESTDIR · In Automake, don't try to run manual tests in installcheck · In CMake, don't run manual-tcp test as an automated test · Add travis-ci.org build machinery D-Bus 1.10.8 (2016-03-07) == The “digestive biscuits” release. Fixes: • Enable "large file support" on systems where it exists: dbus-daemon is not expected to open large files, but it might need to stat files that happen to have large inode numbers (fd.o #93545, Hongxu Jia) • Eliminate padding inside DBusMessageIter on 64-bit platforms, which might result in a pedantic C compiler not copying the entire contents of a DBusMessageIter; statically assert that this is not an ABI change in practice (fd.o #94136, Simon McVittie) • Document dbus-test-tool echo --sleep-ms=N instead of incorrect --sleep=N (fd.o #94244, Dmitri Iouchtchenko) • Correctly report test failures in C tests from run-test.sh (fd.o #93379; amit tewari, Simon McVittie) • When tests are enabled, run all the marshal-validate tests, not just the even-numbered ones (fd.o #93908, Nick Lewycky) • Correct the expected error from one marshal-validate test, which was previously not run due to the above bug (fd.o #93908, Simon McVittie) D-Bus 1.10.6 (2015-12-01) == The “marzipan beetles” release. Fixes: • On Unix when running tests as root, don't assert that root and the dbus-daemon user can still call UpdateActivationEnvironment; assert that those privileged users can call BecomeMonitor instead (fd.o #93036, Simon McVittie) • On Windows, fix a memory leak in the autolaunch transport (fd.o #92899, Simon McVittie) • On Windows Autotools builds, don't run tests that rely on dbus-run-session and other Unix-specifics (fd.o #92899, Simon McVittie) D-Bus 1.10.4 (2015-11-17) == The “Frostburn Canyon” release. Enhancements: • GetConnectionCredentials, GetConnectionUnixUser and GetConnectionUnixProcessID with argument "org.freedesktop.DBus" will now return details of the dbus-daemon itself. This is required to be able to call SetEnvironment on systemd. (fd.o #92857, Jan Alexander Steffens) Fixes: • Make UpdateActivationEnvironment always fail with AccessDenied on the system bus. Previously, it was possible to configure it so root could call it, but the environment variables were not actually used, because the launch helper would discard them. (fd.o #92857, Jan Alexander Steffens) • On Unix with --systemd-activation on a user bus, make UpdateActivationEnvironment pass on its arguments to systemd's SetEnvironment method, solving inconsistency between the environments used for traditional activation and systemd user-service activation. (fd.o #92857, Jan Alexander Steffens) • On Windows, don't crash if or --syslog is used (fd.o #92538, Ralf Habacker) • On Windows, fix a memory leak when setting a DBusError from a Windows error (fd.o #92721, Ralf Habacker) • On Windows, don't go into infinite recursion if we abort the process with backtraces enabled (fd.o #92721, Ralf Habacker) • Fix various failing tests, variously on Windows and cross-platform: · don't test system.conf features (users, groups) that only make sense on the system bus, which is not supported on Windows · don't call _dbus_warn() when we skip a test, since it is fatal · fix computation of expected · when running TAP tests, translate newlines to Unix format, fixing cross-compiled tests under Wine on Linux · don't stress-test refcounting under Wine, where it's really slow · stop assuming that a message looped-back to the test will be received immediately · skip some system bus tests on Windows since they make no sense there (fd.o #92538, fd.o #92721; Ralf Habacker, Simon McVittie) D-Bus 1.10.2 (2015-10-26) == The “worst pies in London” release. Fixes: • Correct error handling for activation: if there are multiple attempts to activate the same service and it fails immediately, the first attempt would get the correct reply, but the rest would time out. We now send the same error reply to each attempt. (fd.o #92200, Simon McVittie) • If BecomeMonitor is called with a syntactically invalid match rule, don't crash with an assertion failure, fixing a regression in 1.9.10. This was not exploitable as a denial of service, because the check for a privileged user is done first. (fd.o #92298, Simon McVittie) • On Linux with --enable-user-session, add the bus address to the environment of systemd services for better backwards compatibility (fd.o #92612, Jan Alexander Steffens) • On Windows, fix the logic for replacing the installation prefix in service files' Exec lines (fd.o #83539; Milan Crha, Simon McVittie) • On Windows, if installed in the conventional layout with ${prefix}/etc and ${prefix}/share, use relative paths between bus configuration files to allow the tree to be relocated (fd.o #92028, Simon McVittie) • Make more of the regression tests pass in Windows builds (fd.o #92538, Simon McVittie) D-Bus 1.10.0 (2015-08-25) == The “0x20” release. This is a new stable branch, recommended for use in OS distributions. Fixes since 1.9.20: • distribute test/tap-test.sh.in, even if the tarball was built without tests enabled (fd.o #91684, Simon McVittie) • work around a fd leak in libcap-ng < 0.7.7 (fd.o #91684, Simon McVittie) Summary of major changes since 1.8.0: • The basic setup for the well-known system and session buses is now done in read-only files in ${datadir} (normally /usr/share). See the NEWS entry for 1.9.18 for details. • AppArmor integration has been merged, with features similar to the pre-existing SELinux integration. It is mostly compatible with the patches previously shipped by Ubuntu, with one significant change: Ubuntu's GetConnectionAppArmorSecurityContext method has been superseded by GetConnectionCredentials and was not included. • The --enable-user-session configure option can be enabled by OS integrators intending to use systemd to provide a session bus per user (in effect, treating all concurrent graphical and non-graphical login sessions as one large session). • The new listenable address mode "unix:runtime=yes" listens on $XDG_RUNTIME_DIR/bus, the same AF_UNIX socket used by the systemd user session. libdbus and "dbus-launch --autolaunch" will connect to this address by default. GLib ≥ 2.45.3 and sd-bus ≥ 209 have a matching default. • All executables are now dynamically linked to libdbus-1. Previously, some executables, most notably dbus-daemon, were statically linked to a specially-compiled variant of libdbus. This results in various private functions in the _dbus namespace being exposed by the shared library. These are not API, and must not be used outside the dbus source tree. • On platforms with ELF symbol versioning, all public symbols are versioned LIBDBUS_1_3. New bus APIs: • org.freedesktop.DBus.GetConnectionCredentials returns LinuxSecurityLabel where supported • org.freedesktop.DBus.Monitoring interface (privileged) · BecomeMonitor method supersedes match rules with eavesdrop=true, which are now deprecated • org.freedesktop.DBus.Stats interface (semi-privileged) · now enabled by default · new GetAllMatchRules method • org.freedesktop.DBus.Verbose interface (not normally compiled) · toggles the effect of DBUS_VERBOSE New executables: • dbus-test-tool • dbus-update-activation-environment New optional dependencies: • The systemd: pseudo-transport requires libsystemd or libsd-daemon • Complete documentation requires Ducktype and yelp-tools • Full test coverage requires GLib 2.36 and PyGI • AppArmor integration requires libapparmor and optionally libaudit Dependencies removed: • dbus-glib D-Bus 1.9.20 (2015-08-06) == The “Remember Tomorrow” release. This is a release-candidate for D-Bus 1.10.0. OS distribution vendors should test it. Fixes: • Don't second-guess what the ABI of poll() is, allowing it to be used on Integrity RTOS and other unusual platforms (fd.o #90314; Rolland Dudemaine, Simon McVittie) • Don't duplicate audit subsystem integration if AppArmor and SELinux are both enabled (fd.o #89225, Simon McVittie) • Log audit events for AppArmor/SELinux policy violations whenever we have CAP_AUDIT_WRITE, even if not the system bus (fd.o #83856, Laurent Bigonville) D-Bus 1.9.18 (2015-07-21) == The “Pirate Elite” release. Configuration changes: • The basic setup for the well-known system and session buses is now done in read-only files in ${datadir}, moving a step closer to systems that can operate with an empty /etc directory. In increasing order of precedence: · ${datadir}/dbus-1/s*.conf now perform the basic setup such as setting the default message policies. · ${sysconfdir}/dbus-1/s*.conf are now optional. By default dbus still installs a trivial version of each, for documentation purposes; putting configuration directives in these files is deprecated. · ${datadir}/dbus-1/s*.d/ are now available for third-party software to install "drop-in" configuration snippets (any packages using those directories should explicitly depend on at least this version of dbus). · ${sysconfdir}/dbus-1/s*.d/ are also still available for sysadmins or third-party software to install "drop-in" configuration snippets · ${sysconfdir}/dbus-1/s*-local.conf are still available for sysadmins' overrides ${datadir} is normally /usr/share, ${sysconfdir} is normally /etc, and "s*" refers to either system or session as appropriate. (fd.o #89280, Dimitri John Ledkov) Fixes: • Fix a memory leak when GetConnectionCredentials() succeeds (fd.o #91008, Jacek Bukarewicz) • Ensure that dbus-monitor does not reply to messages intended for others, resulting in its own disconnection (fd.o #90952, Simon McVittie) D-Bus 1.9.16 (2015-05-14) == The “titanium barns” release. Dependencies: • Automake 1.13 is now required when compiling from git or modifying the build system. Security hardening: • On Unix platforms, change the default configuration for the session bus to only allow EXTERNAL authentication (secure kernel-mediated credentials-passing), as was already done for the system bus. This avoids falling back to DBUS_COOKIE_SHA1, which relies on strongly unpredictable pseudo-random numbers. If you are using D-Bus over the (unencrypted!) tcp: or nonce-tcp: transport, in conjunction with DBUS_COOKIE_SHA1 and a shared home directory using NFS or similar, you will need to reconfigure the session bus to accept DBUS_COOKIE_SHA1 by commenting out the element. This configuration is not recommended. (fd.o #90414, Simon McVittie) • When asked for random numbers for DBUS_COOKIE_SHA1, the nonce-tcp: transport, UUIDs or any other reason, fail if we cannot obtain entropy (from /dev/urandom or CryptGenRandom()) or an out-of-memory condition occurs, instead of silently falling back to low-entropy pseudorandom numbers from rand(). (fd.o #90414; Simon McVittie, Ralf Habacker) Enhancements: • Add dbus_message_iter_get_element_count() (fd.o #30350; Christian Dywan, Simon McVittie) • Introduce new internal DBusSocket and DBusPollable types so we can stop treating the Windows SOCKET type as if it was int. DBusSocket is specifically a socket, cross-platform. DBusPollable is whatever _dbus_poll() can act on, i.e. a fd on Unix or a SOCKET on Windows. (fd.o #89444; Ralf Habacker, Simon McVittie) • All regression tests now output TAP (fd.o #89846, Simon McVittie) • Internal APIs consistently use signed values for timestamps (fd.o #18494, Peter McCurdy) • Improve diagnostics when UpdateActivationEnvironment calls are rejected (fd.o #88812, Simon McVittie) • Clean up a lot of compiler warnings (fd.o #17289, fd.o #89284; Ralf Habacker, Simon McVittie) Fixes: • Add locking to DBusCounter's reference count and notify function (fd.o #89297, Adrian Szyndela) • Ensure that DBusTransport's reference count is protected by the corresponding DBusConnection's lock (fd.o #90312, Adrian Szyndela) • Correctly release DBusServer mutex before early-return if we run out of memory while copying authentication mechanisms (fd.o #90021, Ralf Habacker) • Make dbus-test-tool and dbus-update-activation-environment portable to Windows (fd.o #90089, Ralf Habacker) • Correctly initialize all fields of DBusTypeReader (fd.o #90021; Ralf Habacker, Simon McVittie) • Fix some missing \n in verbose (debug log) messages (fd.o #90004, Ralf Habacker) • Clean up some memory and fd leaks in test code and tools (fd.o #90021, Ralf Habacker) • Fix a NULL dereference if the dbus-daemon cannot read a configuration directory for a reason that is not ENOENT (fd.o #90021, Ralf Habacker) • CMake generates a versioned shared library even if the revision is 0, as it usually is on the development branch. (fd.o #89450, Ralf Habacker) D-Bus 1.9.14 (2015-03-02) == The “don't stand in the poison cloud” release. Dependencies: • dbus-daemon and dbus-daemon-launch-helper now require libdbus. They were previously linked to a static version of libdbus. • The tests no longer require dbus-glib in order to exercise the libdbus shared library; they are always linked to libdbus now. Build-time configuration: • The new --enable-user-session option, off by default, can be enabled by OS integrators intending to use systemd to provide a session bus per user (in effect, treating all concurrent graphical and non-graphical login sessions as one large session) Enhancements: • All executables are now linked dynamically to libdbus. (fd.o #83115; Bertrand SIMONNET, Simon McVittie, Ralf Habacker) • On platforms that support them (GNU libc and possibly others), libdbus now has versioned symbols for its public API. All public symbols (visible in the header files) are currently versioned as LIBDBUS_1_3; private symbols starting with _dbus or dbus_internal have a version that changes with each release, and must not be used by applications. (also fd.o #83115) • New listenable address mode "unix:runtime=yes" which listens on a real filesystem (non-abstract) socket $XDG_RUNTIME_DIR/bus (fd.o #61303; Colin Walters, Alexander Larsson, Simon McVittie) • Add optional systemd units for a per-user bus listening on $XDG_RUNTIME_DIR/bus (fd.o #61301; Simon McVittie, Colin Walters) • On Unix platforms, both libdbus and "dbus-launch --autolaunch" default to connecting to $XDG_RUNTIME_DIR/bus if it is a socket (also fd.o #61301) • New dbus-update-activation-environment tool uploads environment variables to "dbus-daemon --session" and optionally "systemd --user", primarily as a way to keep the per-user bus compatible with distributions' existing X11 login scripts (also fd.o #61301) • elements in dbus-daemon configuration are now silently ignored if the directory does not exist. (fd.o #89280, Dimitri John Ledkov) • Add microsecond-resolution timestamps to the default output of dbus-monitor and dbus-send (fd.o #88896; Ralf Habacker, Simon McVittie) Fixes: • Fix a race condition in the 'monitor' test introduced in 1.9.10 (fd.o #89222, Simon McVittie) D-Bus 1.9.12 (2015-02-19) == The “monster lasagna” release. Dependencies: • Ducktype and yelp-tools are now required to build complete documentation (they are optional for normal builds). Enhancements: • D-Bus Specification version 0.26 · GetConnectionCredentials can return LinuxSecurityLabel or WindowsSID · document the BecomeMonitor method • On Linux, add LinuxSecurityLabel to GetConnectionCredentials (fd.o #89041; Tyler Hicks, Simon McVittie) • On Linux, add support for AppArmor mediation of message sending and receiving and name ownership (paralleling existing SELinux mediation support), and eavesdropping (a new check, currently AppArmor-specific) (fd.o #75113; John Johansen, Tyler Hicks, Simon McVittie) • In dbus-send and dbus-monitor, pretty-print \0-terminated bytestrings that have printable ASCII contents; we previously only did this for unterminated bytestrings (fd.o #89109, Simon McVittie) • Add a guide to designing good D-Bus APIs (fd.o #88994, Philip Withnall) • On Windows, add WindowsSID to GetConnectionCredentials (fd.o #54445, Ralf Habacker) • Improve clarity of dbus-monitor --profile output and add more columns (fd.o #89165, Ralf Habacker) • Add a man page for dbus-test-tool, and build it under CMake as well as Autotools (fd.o#89086, Simon McVittie) • If dbus-daemon was compiled with --enable-verbose, add a D-Bus API to control it at runtime, overriding the DBUS_VERBOSE environment variable (fd.o #88896, Ralf Habacker) Fixes: • Reduce the number of file descriptors used in the fd-passing test, avoiding failure under the default Linux fd limit, and automatically skip it if the rlimit is too small (fd.o #88998, Simon McVittie) D-Bus 1.9.10 (2015-02-09) == The “sad cyborgs” release. Security fixes merged from 1.8.16: • Do not allow non-uid-0 processes to send forged ActivationFailure messages. On Linux systems with systemd activation, this would allow a local denial of service: unprivileged processes could flood the bus with these forged messages, winning the race with the actual service activation and causing an error reply to be sent back when service auto-activation was requested. This does not prevent the real service from being started, so the attack only works while the real service is not running. (CVE-2015-0245, fd.o #88811; Simon McVittie) Enhancements: • The new Monitoring interface in the dbus-daemon lets dbus-monitor and similar tools receive messages without altering the security properties of the system bus, by calling the new BecomeMonitor method on a private connection. This bypasses the normal and rules entirely, so to preserve normal message-privacy assumptions, only root is allowed to do this on the system bus. Restricted environments, such as Linux with LSMs, should lock down access to the Monitoring interface. (fd.o #46787, Simon McVittie) • dbus-monitor uses BecomeMonitor to capture more traffic, if the dbus-daemon supports it and access permissions allow it. It still supports the previous approach ("eavesdropping" match rules) for compatibility with older bus daemons. (fd.o #46787, Simon) • dbus-monitor can now log the message stream as binary data for later analysis, with either no extra framing beyond the normal D-Bus headers, or libpcap-compatible framing treating each D-Bus message as a captured packet. (fd.o #46787, Simon) Other fixes: • Fix some CMake build regressions (fd.o #88964, Ralf Habacker) • On Unix, forcibly terminate regression tests after 60 seconds to prevent them from blocking continuous integration frameworks (fd.o #46787, Simon) D-Bus 1.9.8 (2015-02-03) == The “all the types of precipitation” release. Dependencies: • full test coverage now requires GLib 2.36 • full test coverage now requires PyGI (PyGObject 3, "import gi.repository.GObject") instead of the obsolete PyGObject 2 ("import gobject") Enhancements: • add GLib-style "installed tests" (fd.o #88810, Simon McVittie) • better regression test coverage, including systemd activation (fd.o #57952, #88810; Simon McVittie) Fixes: • fatal errors correctly make the dbus-daemon exit even if is turned off (fd.o #88808, Simon McVittie) • TCP sockets on Windows no longer fail to listen approximately 1 time in 256, caused by a logic error that should have always made it fail but was mitigated by incorrect endianness for the port number (fd.o #87999, Ralf Habacker) • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker) • on Windows, allow up to 8K connections to the dbus-daemon instead of the previous 64, completing a previous fix which only worked under Autotools (fd.o #71297, Ralf Habacker) • on Windows, if the IP family is unspecified only use IPv4, to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker) • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie) • lcov code coverage analysis works again (fd.o #88808, Simon McVittie) • fix an unused function error with --disable-embedded-tests (fd.o #87837, Thiago Macieira) D-Bus 1.9.6 (2015-01-05) == The “I do have a bread knife” release. Security hardening: • Do not allow calls to UpdateActivationEnvironment from uids other than the uid of the dbus-daemon. If a system service installs unsafe security policy rules that allow arbitrary method calls (such as CVE-2014-8148) then this prevents memory consumption and possible privilege escalation via UpdateActivationEnvironment. We believe that in practice, privilege escalation here is avoided by dbus-daemon-launch-helper sanitizing its environment; but it seems better to be safe. • Do not allow calls to UpdateActivationEnvironment or the Stats interface on object paths other than /org/freedesktop/DBus. Some system services install unsafe security policy rules that allow arbitrary method calls to any destination, method and interface with a specified object path; while less bad than allowing arbitrary method calls, these security policies are still harmful, since dbus-daemon normally offers the same API on all object paths and other system services might behave similarly. Other fixes: • Add missing initialization so GetExtendedTcpTable doesn't crash on Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко) D-Bus 1.9.4 (2014-11-24) == The “extra-sturdy caramel” release. Fixes: • Partially revert the CVE-2014-3639 patch by increasing the default authentication timeout on the system bus from 5 seconds back to 30 seconds, since this has been reported to cause boot regressions for some users, mostly with parallel boot (systemd) on slower hardware. On fast systems where local users are considered particularly hostile, administrators can return to the 5 second timeout (or any other value in milliseconds) by saving this as /etc/dbus-1/system-local.conf: 5000 (fd.o #86431, Simon McVittie) • Add a message in syslog/the Journal when the auth_timeout is exceeded (fd.o #86431, Simon McVittie) • Send back an AccessDenied error if the addressed recipient is not allowed to receive a message (and in builds with assertions enabled, don't assert under the same conditions). (fd.o #86194, Jacek Bukarewicz) D-Bus 1.9.2 (2014-11-10) == The “structurally unsound flapjack” release. Security fixes: • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536 so that CVE-2014-3636 part A cannot exhaust the system bus' file descriptors, completing the incomplete fix in 1.8.8. (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy) Enhancements: • D-Bus Specification version 0.25 · new value 'const' for EmitsChangedSignal annotation (fd.o #72958, Lennart Poettering) · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar (fd.o #83449; Lennart Poettering, Simon McVittie) · annotate table of types with reserved/basic/container, and for basic types, fixed/string-like · clarify arbitrary limits by quoting them in mebibytes • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag (fd.o #83449, Simon McVittie) • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands, useful for debugging and performance testing: · dbus-test-tool spam: send repeated messages · dbus-test-tool echo: send an empty reply for all method calls · dbus-test-tool black-hole: do not reply to method calls (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson) • Add support for process ID in credentials-passing on NetBSD (fd.o #69702, Patrick Welche) • Add an example script to find potentially undesired match rules (fd.o #84598, Alban Crequy) • Document the central assumption that makes our use of credentials-passing secure (fd.o #83499, Simon McVittie) • Replace the dbus-glib section of the tutorial with a GDBus recommendation, and add some links to GDBus and QtDBus documentation (fd.o #25140, Simon McVittie) Fixes: • Use a less confusing NoReply message when disconnected with a reply pending (fd.o #76112, Simon McVittie) • Make the .pc file relocatable by letting pkg-config do all variable expansion itself (fd.o #75858, Руслан Ижбулатов) • Fix a build failure on platforms with kqueue, which regressed in 1.9.0 (fd.o #85563, Patrick Welche) • Consistently save errno after socket calls (fd.o #83625, Simon McVittie) • In dbus-spawn, when the grandchild process exits due to a failed exec(), do not lose the exec() errno (fd.o #24821, Simon McVittie) • Do not fail the tests if a parent process has leaked non-close-on-exec file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie) • Do not fail the tests on Unix platforms with incomplete credentials-passing support, but do fail if we can't pass credentials on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD (fd.o #69702, Simon McVittie) • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing when building with cmake, and expand test coverage there (fd.o #73689; Ralf Habacker, Simon McVittie) D-Bus 1.9.0 (2014-10-01) == The “tiered cheeses” release. Requirements: • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now requires either the libsystemd or libsd-daemon shared library, dropping the embedded convenience copy of sd-daemon (fd.o #71818, Simon) Build-time configuration changes: • The Stats interface is now enabled by default, and locked-down to root-only on the system bus. Configure with --disable-stats to disable it altogether on memory- or disk-constrained systems, or see ${docdir}/examples/ to open it up to non-root users on the system bus or restrict access on the session bus. (fd.o #80759; Simon McVittie, Alban Crequy) • The CMake build system now builds the same shared library name as Autotools on at least Linux and Windows: - on Linux (and perhaps other Unix platforms), it previously built libdbus-1.so, but now builds libdbus-1.so.3.* with development symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3 - on Windows, it previously built either libdbus-1.dll (release) or libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to libdbus-1.dll for compatibility with older applications. (fd.o #74117, Ralf Habacker) Enhancements: • D-Bus Specification version 0.24 · document how to quote match rules (fd.o #24307, Simon McVittie) · explicitly say that most message types never expect a reply regardles of whether they have NO_REPLY_EXPECTED (fd.o #75749, Simon McVittie) • on Unix platforms, disable Nagle's algorithm on TCP connections to improve initial latency (fd.o #75544, Matt Hoosier) • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD (fd.o #69702, Patrick Welche) • in dbus-monitor, print more information about file descriptors (fd.o #80603, Alban Crequy) • do not install system bus configuration if built for Windows (fd.o #83583; Ralf Habacker, Simon McVittie) • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy) • Add a regression test for file descriptor passing (fd.o #83622, Simon McVittie) Fixes: • fix an incorrect error message if a Unix socket path is too long (fd.o #73887, Antoine Jacoutot) • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto, fixing documentation generation (fd.o #75860, Руслан Ижбулатов) • in Unix with X11, avoid giving dbus-launch a misleading argv[0] in ps(1) (fd.o #69716, Chengwei Yang) • avoid calling poll() with timeout < -1, which is considered invalid on FreeBSD and NetBSD (fd.o #78480, Jaap Boender) • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc (like Mac OS X 10.6), or available in libc but unsupported by the kernel (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche) • Fix include path for test/internal/*.c with cmake (Ralf Habacker) • Documentation improvements (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen) • in dbus-monitor, do not leak file descriptors that we have monitored (fd.o #80603, Alban Crequy) • Set the close-on-exec flag for the inotify file descriptor, even if built with CMake or older libc (fd.o #73689, Simon McVittie) • Remove some LGPL code from the Windows dbus-daemon (fd.o #57272, Ralf Habacker) D-Bus 1.8.8 (2014-09-16) == The "smashy smashy egg man" release. Security fixes: • Do not accept an extra fd in the padding of a cmsg message, which could lead to a 4-byte heap buffer overrun. (CVE-2014-3635, fd.o #83622; Simon McVittie) • Reduce default for maximum Unix file descriptors passed per message from 1024 to 16, preventing a uid with the default maximum number of connections from exhausting the system bus' file descriptors under Linux's default rlimit. Distributors or system administrators with a more restrictive fd limit may wish to reduce these limits further. Additionally, on Linux this prevents a second denial of service in which the dbus-daemon can be made to exceed the maximum number of fds per sendmsg() and disconnect the process that would have received them. (CVE-2014-3636, fd.o #82820; Alban Crequy) • Disconnect connections that still have a fd pending unmarshalling after a new configurable limit, pending_fd_timeout (defaulting to 150 seconds), removing the possibility of creating an abusive connection that cannot be disconnected by setting up a circular reference to a connection's file descriptor. (CVE-2014-3637, fd.o #80559; Alban Crequy) • Reduce default for maximum pending replies per connection from 8192 to 128, mitigating an algorithmic complexity denial-of-service attack (CVE-2014-3638, fd.o #81053; Alban Crequy) • Reduce default for authentication timeout on the system bus from 30 seconds to 5 seconds, avoiding denial of service by using up all unauthenticated connection slots; and when all unauthenticated connection slots are used up, make new connection attempts block instead of disconnecting them. (CVE-2014-3639, fd.o #80919; Alban Crequy) Other fixes: • Check for libsystemd from systemd >= 209, falling back to the older separate libraries if not found (Umut Tezduyar Lindskog, Simon McVittie) • On Linux, use prctl() to disable core dumps from a test executable that deliberately raises SIGSEGV to test dbus-daemon's handling of that condition (fd.o #83772, Simon McVittie) • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232; Alban Crequy) • Improve documentation for running tests on Windows (fd.o #41252, Ralf Habacker) D-Bus 1.8.6 (2014-06-02) == Security fixes: • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop the message. This prevents an attack in which a malicious client can make dbus-daemon disconnect a system service, which is a local denial of service. (fd.o #80163, CVE-2014-3532; Alban Crequy) • Track remaining Unix file descriptors correctly when more than one message in quick succession contains fds. This prevents another attack in which a malicious client can make dbus-daemon disconnect a system service. (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez, Simon McVittie, Alban Crequy) Other fixes: • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot attach to a session, kill the dbus-daemon as intended (fd.o #74698, Роман Донченко) D-Bus 1.8.4 (2014-06-10) == Security fix: • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service flaw in dbus-daemon, part of the reference implementation of D-Bus. Additionally, in highly unusual environments the same flaw could lead to a side channel between processes that should not be able to communicate. (CVE-2014-3477, fd.o #78979) D-Bus 1.8.2 (2014-04-30) == The “nobody wants red” release. Enhancements: • in the CMake build system, add some hints for Linux users cross-compiling Windows D-Bus binaries to be able to run tests under Wine (fd.o #41252, Ralf Habacker) • add Documentation key to dbus.service (fd.o #77447, Cameron Norman) Fixes: • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id to /var/lib/dbus/machine-id instead of generating an entirely new ID (fd.o #77941, Simon McVittie) • if dbus-launch receives an X error very quickly, do not kill unrelated processes (fd.o #74698, Роман Донченко) • on Windows, allow up to 8K connections to the dbus-daemon, instead of the previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker) • cope with \r\n newlines in regression tests, since on Windows, dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов) D-Bus 1.8.0 (2014-01-20) == The “Wolverine distrusts my printer” release. This starts a new stable branch. The 1.6.x branch is now considered to be outdated, and will only receive fixes for serious bugs such as security flaws. The 1.4.x and 1.2.x branches no longer have upstream support and are unlikely to get any more releases, but if distributors still need to support them, please share security patches via upstream. Summary of changes since 1.6.x: • libdbus always behaves as if dbus_threads_init_default() had been called (thread-safety by default) • new dbus-run-session tool, replacing certain misuses of dbus-launch • dbus-monitor can talk to outdated versions of dbus-daemon again • new org.freedesktop.DBus.GetConnectionCredentials method • GetConnectionUnixProcessID also works correctly on Windows, returning the Windows process ID • GetConnectionWindowsSID returns the correct SID on Windows • expat is required, libxml2 can no longer be used as a substitute • the userDB cache is required, and cannot be disabled • a 64-bit integer type (either int, long, long long or _int64) is required • better systemd-journald integration on Linux • fixed long-standing fd and array leaks when failing to parse a message • fixed referenced-but-never-freed parent nodes (effectively memory leaks) when using certain object-path allocation patterns, notably in Avahi • better defaults for Windows support • better CMake support • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd • the source language for the man pages is now Docbook XML Enhancements since 1.7.10: • Enhance the CMake build system to check for GLib and compile/run a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker) Fixes since 1.7.10: • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840, Ralf Habacker) • fix compilation of systemd journal support on older systemd versions where sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker) • fix compilation on older MSVC versions by including stdlib.h (fd.o #73455, Ralf Habacker) • Allow to appear in an included configuration file (fd.o #73475, Matt Hoosier) Test behaviour changes since 1.7.10: • If the tests crash with an assertion failure, they no longer default to blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the environment if you want the old behaviour. • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests can be run with an external dbus-daemon by setting DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require an unusually-configured dbus-daemon are skipped. D-Bus 1.7.10 (2014-01-06) == The “weighted companion cube” release. This is a release candidate for D-Bus 1.8. D-Bus Specification 0.23: • don't require messages with no INTERFACE to be dispatched (fd.o #68597, Simon McVittie) • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301, Chengwei Yang) • define "listenable" and "connectable" addresses, and discuss the difference (fd.o #61303, Simon McVittie) Enhancements: • support printing Unix file descriptors in dbus-send, dbus-monitor (fd.o #70592, Robert Ancell) • don't install systemd units if --disable-systemd is given (fd.o #71818, Chengwei Yang) Fixes: • don't leak memory on out-of-memory while listing activatable or active services (fd.o #71526, Radoslaw Pajak) • fix undefined behaviour in a regression test (fd.o #69924, DreamNik) • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang) • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC and DBUS__SEND_MSG are numerically equal to their values in the reference policy (fd.o #88719, osmond sun) • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers (fd.o #71366, Matt Fischer) • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and winsock2.h (fd.o #71405, Matt Fischer) • do not return failure from _dbus_read_nonce() with no error set, preventing a potential crash (fd.o #72298, Chengwei Yang) • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue, preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang) • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets, which doesn't do anything anyway on at least Linux and FreeBSD (fd.o #69492, Simon McVittie) • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from sendmsg() with SCM_CREDS (retrying with plain send()), and looking for credentials more correctly (fd.o #69492, Simon McVittie) • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid getting mixed up in XDG/systemd "user sessions" (fd.o #61301, Simon McVittie) • refresh cached policy rules for existing connections when bus configuration changes (fd.o #39463, Chengwei Yang) D-Bus 1.7.8 (2013-11-01) == The “extreme hills” release. Dependencies: • If systemd support is enabled, libsystemd-journal is now required. Enhancements: • When activating a non-systemd service under systemd, annotate its stdout/stderr with its bus name in the Journal. Known limitation: because the socket is opened before forking, the process will still be logged as if it had dbus-daemon's process ID and user ID. (fd.o #68559, Chengwei Yang) • Document more configuration elements in dbus-daemon(1) (fd.o #69125, Chengwei Yang) Fixes: • Don't leak string arrays or fds if dbus_message_iter_get_args_valist() unpacks them and then encounters an error (fd.o #21259, Chengwei Yang) • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write disallowed method calls to the audit log, fixing a regression in 1.7.6 (fd.o #49062, Colin Walters) • path_namespace='/' in match rules incorrectly matched nothing; it now matches everything. (fd.o #70799, Simon McVittie) D-Bus 1.7.6 (2013-10-09) == The “CSI Shrewsbury” release. Build-time configuration changes: • Directory change notification via dnotify on Linux is no longer supported; it hadn't compiled successfully since 2010 in any case. If you don't have inotify (Linux) or kqueue (*BSD), you will need to send SIGHUP to the dbus-daemon when its configuration changes. (fd.o #33001, Chengwei Yang) • Compiling with --disable-userdb-cache is no longer supported; it didn't work since at least 2008, and would lead to an extremely slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947; Chengwei Yang) • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent with the Autotools build system. (fd.o #66142, Chengwei Yang) • --with-valgrind=auto enables Valgrind instrumentation if and only if valgrind headers are available. The default is still --with-valgrind=no. (fd.o #56925, Simon McVittie) Dependencies: • Platforms with no 64-bit integer type are no longer supported. (fd.o #65429, Simon McVittie) • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie) • Full test coverage no longer requires dbus-glib, although the tests do not exercise the shared library (only a static copy) if dbus-glib is missing. (fd.o #68852, Simon McVittie) Enhancements: • D-Bus Specification 0.22 · Document GetAdtAuditSessionData() and GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon) · Fix example .service file (fd.o #66481, Chengwei Yang) · Don't claim D-Bus is "low-latency" (lower than what?), just give factual statements about it supporting async use (fd.o #65141, Justin Lee) · Document the contents of .service files, and the fact that system services' filenames are constrained (fd.o #66608; Simon McVittie, Chengwei Yang) • Be thread-safe by default on all platforms, even if dbus_threads_init_default() has not been called. For compatibility with older libdbus, library users should continue to call dbus_threads_init_default(): it is harmless to do so. (fd.o #54972, Simon McVittie) • Add GetConnectionCredentials() method (fd.o #54445, Simon) • New API: dbus_setenv(), a simple wrapper around setenv(). Note that this is not thread-safe. (fd.o #39196, Simon) • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection, like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS (connect to a given bus, like dbus-monitor --address=ADDRESS). dbus-send --address still exists for backwards compatibility, but is no longer documented. (fd.o #48816, Andrey Mazo) • Windows-specific: · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852, Simon McVittie) Fixes: • Avoid an infinite busy-loop if a signal interrupts waitpid() (fd.o #68945, Simon McVittie) • Clean up memory for parent nodes when objects are unexported (fd.o #60176, Thomas Fitzsimmons) • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as documented. Previously, it assumed its second parameter was TRUE. (fd.o #69165, Chengwei Yang) • Escape addresses containing non-ASCII characters correctly (fd.o #53499, Chengwei Yang) • Document search order correctly (fd.o #66994, Chengwei Yang) • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4. (fd.o #65923, Chengwei Yang) • If malloc() returns NULL in _dbus_string_init() or similar, don't free an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang) • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list that was never va_start()ed (fd.o #66300, Chengwei Yang) • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang) • fix a regression test on platforms with strict alignment (fd.o #67279, Colin Walters) • Avoid calling function parameters "interface" since certain Windows headers have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov) • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang) • Various thread-safety improvements to static variables (fd.o #68610, Simon McVittie) • Make "make -j check" work (fd.o #68852, Simon McVittie) • Fix a NULL pointer dereference on an unlikely error path (fd.o #69327, Sviatoslav Chagaev) • Improve valgrind memory pool tracking (fd.o #69326, Sviatoslav Chagaev) • Don't over-allocate memory in dbus-monitor (fd.o #69329, Sviatoslav Chagaev) • dbus-monitor can monitor dbus-daemon < 1.5.6 again (fd.o #66107, Chengwei Yang) • Unix-specific: · If accept4() fails with EINVAL, as it can on older Linux kernels with newer glibc, try accept() instead of going into a busy-loop. (fd.o #69026, Chengwei Yang) · If socket() or socketpair() fails with EINVAL or EPROTOTYPE, for instance on Hurd or older Linux with a new glibc, try without SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang) · Fix a file descriptor leak on an error code path. (fd.o #69182, Sviatoslav Chagaev) · dbus-run-session: clear some unwanted environment variables (fd.o #39196, Simon) · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang) · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon) · Use dbus-launch from the builddir for testing, not the installed copy (fd.o #37849, Chengwei Yang) · Fix compilation if writev() is unavailable (fd.o #69409, Vasiliy Balyasnyy) · Remove broken support for LOCAL_CREDS credentials passing, and document where each credential-passing scheme is used (fd.o #60340, Simon McVittie) · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality (fd.o #35881, #69787; Chengwei Yang) · dbus-monitor: be portable to NetBSD (fd.o #69842, Chengwei Yang) · dbus-launch: stop using non-portable asprintf (fd.o #37849, Simon) · Improve error reporting from the setuid activation helper (fd.o #66728, Chengwei Yang) • Windows-specific: · Remove unavailable command-line options from 'dbus-daemon --help' (fd.o #42441, Ralf Habacker) · Add support for looking up local TCPv4 clients' credentials on Windows XP via the undocumented AllocateAndGetTcpExTableFromStack function (fd.o #66060, Ralf Habacker) · Fix insufficient dependency-tracking (fd.o #68505, Simon McVittie) · Don't include wspiapi.h, fixing a compiler warning (fd.o #68852, Simon McVittie) • Internal changes: · add DBUS_ENABLE_ASSERT, DBUS_ENABLE_CHECKS for less confusing conditionals (fd.o #66142, Chengwei Yang) · improve verbose-mode output (fd.o #63047, Colin Walters) · consolidate Autotools and CMake build (fd.o #64875, Ralf Habacker) · fix various unused variables, unusual build configurations etc. (fd.o #65712, #65990, #66005, #66257, #69165, #69410, #70218; Chengwei Yang, Vasiliy Balyasnyy) D-Bus 1.7.4 (2013-06-13) == The “but is your thread-safety thread-safe?” release. Security fixes: • CVE-2013-2168: Fix misuse of va_list that could be used as a denial of service for system services. Vulnerability reported by Alexandru Cornea. (Simon) Dependencies: • The Windows version of libdbus now contains a C++ source file, used to provide global initialization when the library is loaded. gcc (mingw*) users should ensure that g++ is also installed. • The libxml2-based configuration reader (which hasn't worked for 2.5 years, and was never the recommended option) has been removed. Expat is now a hard dependency. Enhancements: • It should now be safe to call dbus_threads_init_default() from any thread, at any time. Authors of loadable modules and plugins that use libdbus should consider doing so during initialization. (fd.o #54972, Simon McVittie) • Improve dbus-send documentation and command-line parsing (fd.o #65424, Chengwei Yang) Unix-specific: · dbus-run-session: experimental new tool to start a temporary D-Bus session, e.g. for regression tests or a text console, replacing certain uses of dbus-launch which weren't really correct (fd.o #39196, Simon) Other fixes: • In dbus-daemon, don't crash if a .service file starts with key=value (fd.o #60853, Chengwei Yang) • Unix-specific: · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog on a platform not defining LOG_PERROR, such as Solaris or QNX. This regressed in 1.7.0. (Simon) · Fix an assertion failure if we try to activate systemd services before systemd connects to the bus (fd.o #50199, Chengwei Yang) · Avoid compiler warnings for ignoring the return from write() (Chengwei Yang) • Windows-specific: · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/ so that Windows finds them (fd.o #59733, Ralf Habacker) D-Bus 1.7.2 (2013-04-25) == The “only partially opaque” release. Configuration changes: • On non-QNX Unix platforms, the default limit on fds per message in the session bus configuration has reduced from 4096 to 1024. The default limit used on the system bus was already 1024. On QNX, both limits are reduced further, to 128. Enhancements: • D-Bus Specification 0.21 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF, U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072, Simon McVittie) Fixes: • Diagnose incorrect use of dbus_connection_get_data() with negative slot (i.e. before allocating the slot) rather than returning junk (fd.o #63127, Dan Williams) • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker, Simon McVittie) • Unix-specific: · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie) · Under systemd, log to syslog only, not stderr, avoiding duplication (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen) · Under systemd, remove unnecessary dependency on syslog.socket (fd.o #63531, Cristian Rodríguez) · Include alloca.h for alloca() if available, fixing compilation on Solaris 10 (fd.o #63071, Dagobert Michelsen) · Allow use of systemd-logind without the rest of systemd (fd.o #62585, Martin Pitt) · When built with CMake, link to librt and use the right path for meinproc's XSLT stylesheets (fd.o #61637, Ralf Habacker) · Reduce the default limit on number of fds per message to 128 under QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer) • Windows-specific: · Do not claim that all bus clients have the dbus-daemon's credentials; pick up local TCPv4 clients' credentials (process ID and security identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787, Ralf Habacker) D-Bus 1.7.0 (2013-02-22) == The "Disingenuous Assertions" release. This is a new development release, starting the 1.7.x branch. D-Bus 1.6 remains the recommended version for long-term-supported distributions or the upcoming GNOME 3.8 release. Build-time configuration changes: • The --with-dbus-session-bus-default-address configure option is no longer supported. Use the new --with-dbus-session-bus-connect-address and --with-dbus-session-bus-listen-address options instead. On Windows, you usually want them to have the same argument; on Unix, the defaults are usually correct. • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead. • cmake/cross-compile.sh has been removed. Instead, please use a cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at ; or use Autotools as documented in "info automake Cross-Compilation", and set PKG_CONFIG_PATH appropriately. Requirements: • Man pages now require xmlto (or either xmlto or meinproc, if using CMake). • man2html is no longer used. Enhancements: • D-Bus Specification 0.20 · actually say that /org/freedesktop/DBus is the object that implements o.fd.DBus (fd.o #51865, Colin Walters) · various reorganisation for better clarity (fd.o #38252, Simon McVittie) · stop claiming that all basic types work just like INT32 (strings don't!) • The "source code" for the man pages is now Docbook XML, eliminating the outdated duplicate copies used when building with CMake. (fd.o #59805; Ralf Habacker, Simon McVittie) Fixes: • In the activation helper, when compiled for tests, do not reset the system bus address, fixing the regression tests. (fd.o #52202, Simon) • Fix building with Valgrind 3.8, at the cost of causing harmless warnings with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan) • Merge from system-local.conf if necessary (fd.o #51560, Krzysztof Konopko) • Under CMake, prefer xmlto over meinproc (fd.o #59733, Ralf Habacker) • Stop duplicating CMake's own logic to find libexpat (fd.o #59733, Ralf Habacker) • Don't assume CMake host and build system are the same (fd.o #59733, Ralf Habacker) • Avoid deprecation warnings for GLib 2.35 (fd.o #59971, Simon McVittie) • Unix-specific: · Check for functions in libpthread correctly, fixing compilation on (at least) OpenBSD (fd.o #47239, Simon) · Don't leak temporary fds pointing to /dev/null (fd.o #56927, Michel HERMIER) · Update sd-daemon.[ch] from systemd (fd.o #60681) · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer) • Windows-specific: · The default session bus listening and connecting address is now "autolaunch:", which makes D-Bus on Windows interoperate with itself and GDBus "out of the box". Use the configure options and cmake variables described above if you require a different autolaunch scope. (fd.o #38201, Simon McVittie) · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker) • Create session.d, system.d directories under CMake (fd.o #41319, Ralf Habacker) D-Bus 1.6.8 (2012-09-28) == The "Fix one thing, break another" release. • Follow up to CVE-2012-3524: The additional hardening work to use __secure_getenv() as a followup to bug #52202 broke certain configurations of gnome-keyring. Given the difficulty of making this work without extensive changes to gnome-keyring, use of __secure_getenv() is deferred. D-Bus 1.6.6 (2012-09-28) == The "Clear the environment in your setuid binaries, please" release. • CVE-2012-3524: Don't access environment variables (fd.o #52202) Thanks to work and input from Colin Walters, Simon McVittie, Geoffrey Thomas, and others. • Unix-specific: · Fix compilation on Solaris (fd.o #53286, Jonathan Perkin) · Work around interdependent headers on OpenBSD by including sys/types.h before each use of sys/socket.h (fd.o #54418, Brad Smith) D-Bus 1.6.4 (2012-07-18) == • Detect that users are "at the console" correctly when configured with a non-default path such as --enable-console-auth-dir=/run/console (fd.o #51521, Dave Reisner) • Remove an incorrect assertion from DBusTransport (fd.o #51657, Simon McVittie) • Make --enable-developer default to "no" (regression in 1.6.2; fd.o #51657, Simon McVittie) • Windows-specific: · Launch dbus-daemon correctly if its path contains a space (fd.o #49450, Wolfgang Baron) D-Bus 1.6.2 (2012-06-27) == The "Ice Cabbage" release. • Change how we create /var/lib/dbus so it works under Automake >= 1.11.4 (fd.o #51406, Simon McVittie) • Don't return from dbus_pending_call_set_notify with a lock held on OOM (fd.o #51032, Simon McVittie) • Disconnect "developer mode" (assertions, verbose mode etc.) from Automake maintainer mode. D-Bus developers should now configure with --enable-developer. Automake maintainer mode is now on by default; distributions can disable it with --disable-maintainer-mode. (fd.o #34671, Simon McVittie) • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds, fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie) • Unix-specific: · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie) D-Bus 1.6.0 (2012-06-05) == The “soul of this machine has improved” release. This version starts a new stable branch of D-Bus: only bug fixes will be accepted into 1.6.x. Other changes will now go to the 1.7.x branch. Summary of changes since 1.4.x: • New requirements · PTHREAD_MUTEX_RECURSIVE on Unix · compiler support for 64-bit integers (int64_t or equivalent) • D-Bus Specification v0.19 • New dbus-daemon features · rules allow the service to own names like com.example.Service.Instance3 · optional systemd integration when checking at_console policies · --nopidfile option, mainly for use by systemd · path_namespace and arg0namespace may appear in match rules · eavesdropping is disabled unless the match rule contains eavesdrop=true • New public API · functions to validate various string types (dbus_validate_path() etc.) · dbus_type_is_valid() · DBusBasicValue, a union of every basic type • Bug fixes · removed an unsafe reimplementation of recursive mutexes · dbus-daemon no longer busy-loops if it has far too many file descriptors · dbus-daemon.exe --print-address works on Windows · all the other bug fixes from 1.4.20 • Other major implementation changes · on Linux, dbus-daemon uses epoll if supported, for better scalability · dbus_threads_init() ignores its argument and behaves like dbus_threads_init_default() instead · removed the per-connection link cache, improving dbus-daemon performance • Developer features · optional Valgrind instrumentation (--with-valgrind) · optional Stats interface on the dbus-daemon (--enable-stats) · optionally abort whenever malloc() fails (--enable-embedded-tests and export DBUS_MALLOC_CANNOT_FAIL=1) Changes since 1.5.12: • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1 spec-compliance (fd.o #48580, David Zeuthen) • Don't use install(1) within the source/build trees, fixing the build as non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot) • Add missing commas in some tcp and nonce-tcp addresses, and remove an unused duplicate copy of the nonce-tcp transport in Windows builds (fd.o #45896, Simon McVittie) D-Bus 1.5.12 (2012-03-27) == The “Big Book of Science” release. • Add public API to validate various string types: dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(), dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8() (fd.o #39549, Simon McVittie) • Turn DBusBasicValue into public API so bindings don't need to invent their own "union of everything" type (fd.o #11191, Simon McVittie) • Enumerate data files included in the build rather than using find(1) (fd.o #33840, Simon McVittie) • Add support for policy rules like in dbus-daemon (fd.o #46273, Alban Crequy) • Windows-specific: · make dbus-daemon.exe --print-address (and --print-pid) work again on Win32, but not on WinCE (fd.o #46049, Simon McVittie) · fix duplicate case value when compiling against mingw-w64 (fd.o #47321, Andoni Morales Alastruey) D-Bus 1.5.10 (2012-02-21) == The "fire in Delerium" release. On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base and SUSv2) is now required. • D-Bus Specification 0.19: · Formally define unique connection names and well-known bus names, and document best practices for interface, bus, member and error names, and object paths (fd.o #37095, Simon McVittie) · Document the search path for session and system services on Unix, and where they should be installed by build systems (fd.o #21620, fd.o #35306; Simon McVittie) · Document the systemd transport (fd.o #35232, Lennart Poettering) • Make dbus_threads_init() use the same built-in threading implementation as dbus_threads_init_default(); the user-specified primitives that it takes as a parameter are now ignored (fd.o #43744, Simon McVittie) • Allow all configured auth mechanisms, not just one (fd.o #45106, Pavel Strashkin) • Improve cmake build system (Ralf Habacker): · simplify XML parser dependencies (fd.o #41027) · generate build timestamp (fd.o #41029) · only create batch files on Windows · fix option and cache syntax · add help-options target · share dbus-arch-deps.h.in with autotools rather than having our own version (fd.o #41033) • Build tests successfully with older GLib, as found in e.g. Debian 6 (fd.o #41219, Simon McVittie) • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt) • Build documentation correctly if man2html doesn't support filenames on its command-line (fd.o #43875, Jack Nagel) • Improve test coverage. To get even more coverage, run the tests with DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie) • Reduce the size of the shared library by moving functionality only used by dbus-daemon, tests etc. into their internal library and deleting unused code (fd.o #34976, #39759; Simon McVittie) • Add dbus-daemon --nopidfile option, overriding the configuration, for setups where the default configuration must include to avoid breaking traditional init, but the pid file is in fact unnecessary; use it under systemd to improve startup time a bit (fd.o #45520, Lennart Poettering) • Optionally (if configured --with-valgrind) add instrumentation to debug libdbus and associated tools more meaningfully under Valgrind (fd.o #37286, Simon McVittie) • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie) • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz) • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment, abort on failure to malloc() (like GLib does), to turn runaway memory leaks into a debuggable core-dump if a resource limit is applied (fd.o #41048, Simon McVittie) • Don't crash if realloc() returns NULL in a debug build (fd.o #41048, Simon McVittie) • Unix-specific: · Replace our broken reimplementation of recursive mutexes, which has been broken since 2006, with an ordinary pthreads recursive mutex (fd.o #43744; Sigmund Augdal, Simon McVittie) · Use epoll(7) for a more efficient main loop in Linux; equivalent patches welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris event ports (fd.o #33337; Simon McVittie, Ralf Habacker) · When running under systemd, use it instead of ConsoleKit to check whether to apply at_console policies (fd.o #39609, Lennart Poettering) · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie) · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er) · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck' (fd.o #41218, Simon McVittie) · Stop pretending we respect XDG_DATA_DIRS for system services: the launch helper doesn't obey environment variables to avoid privilege escalation attacks, so make the system bus follow the same rules (fd.o #21620, Simon McVittie) • Windows-specific: · Find the dbus-daemon executable next to the shared library (fd.o #41558; Jesper Dam, Ralf Habacker) · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609, Simon McVittie) D-Bus 1.5.8 (2011-09-21) == The "cross-metering" release. In addition to dead code removal and refactoring, this release contains all of the bugfixes from 1.4.16. • Clean up dead code, and make more warnings fatal in development builds (fd.o #39231, fd.o #41012; Simon McVittie) • If full test coverage is requested via --enable-tests, strictly require Python, pygobject and dbus-python, which are required by some tests; if not, and Python is missing, skip those tests rather than failing (fd.o #37847, Simon McVittie) • When using cmake, provide the same version-info API in the installed headers as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker) • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie) • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters) • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636, Simon McVittie) • Fix duplicates in authors list (Ralf Habacker) • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir) (fd.o #39879, Chris Mayo) • Fix a small memory leak, and a failure to report errors, when updating a service file entry for activation (fd.o #39230, Simon McVittie) • Unix-specific: · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656; Brian Cameron, Simon McVittie) · On systems that use libcap-ng but not systemd, drop supplemental groups when switching to the daemon user (Red Hat #726953, Steve Grubb) · Make the cmake build work again on GNU platforms (fd.o #29228, Simon McVittie) · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h, like Solaris (fd.o #40313, Dagobert Michelsen) · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10 (fd.o #40235, Simon McVittie) · Cope with Unixes that don't have LOG_PERROR, like Solaris 10 (fd.o #39987, Simon McVittie) · Cope with platforms whose vsnprintf violates both POSIX and C99, like Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie) • Windows-specific: · Fix compilation on MSVC, which doesn't understand "inline" with its C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie) · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie) · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie) D-Bus 1.5.6 (2011-07-29) == The "weird, gravy-like aftertaste" release. In addition to new features and refactoring, this release contains all of the bugfixes from 1.4.14. Potentially incompatible (Bustle and similar debugging tools will need changes to work as intended): • Do not allow match rules to "eavesdrop" (receive messages intended for a different recipient) by mistake: eavesdroppers must now opt-in to this behaviour by putting "eavesdrop='true'" in the match rule, which will not have any practical effect on buses where eavesdropping is not allowed (fd.o #37890, Cosimo Alfarano) Other changes: • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252; Cosimo Alfarano, Simon McVittie) · add the "eavesdrop" keyword to match rules · define eavesdropping, unicast messages and broadcast messages · stop claiming that match rules are needed to match unicast messages to you · promote the type system to be a top-level section • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE, and simplify object-path registration (fd.o #38874, Jiří Klimeš) • Consistently use atomic operations on everything that is ever manipulated via atomic ops, as was done for changes to DBusConnection's refcount in 1.4.12 (fd.o #38005, Simon McVittie) • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258, Simon McVittie) • Make "make check" in a clean tree work, by not running tests until test data has been set up (fd.o #34405, Simon McVittie) • The dbus-daemon no longer busy-loops if it has a very large number of file descriptors (fd.o #23194, Simon McVittie) • Refactor message flow through dispatching to avoid locking violations if the bus daemon's message limit is hit; remove the per-connection link cache, which was meant to improve performance, but now reduces it (fd.o #34393, Simon McVittie) • Some cmake fixes (Ralf Habacker) • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610; Simon McVittie, Lennart Poettering) • Stop storing two extra byte order indicators in each D-Bus message (fd.o #38287, Simon McVittie) • Add an optional Stats interface which can be used to get statistics from a running dbus-daemon if enabled at configure time with --enable-stats (fd.o #34040, Simon McVittie) • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie) • Documentation (fd.o #36156, Simon McVittie): · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc · install more documentation automatically, including man2html output · put dbus.devhelp in the right place (it must go in ${htmldir}) • Unix-specific: · look for system services in /lib/dbus-1/system-services in addition to all the other well-known locations; note that this should always be /lib, even on platforms where shared libraries on the root FS would go in /lib64, /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering) · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie) • Windows-specific (Ralf Habacker): · fix use of a mutex for autolaunch server detection · don't crash on malloc failure in _dbus_printf_string_upper_bound D-Bus 1.5.4 (2011-06-10) == Security (local denial of service): • Byte-swap foreign-endian messages correctly, preventing a long-standing local DoS if foreign-endian messages are relayed through the dbus-daemon (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7) (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie) New things: • The constant to use for an infinite timeout now has a name, DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX) which can be used for source compatibility with older versions of libdbus. • If GLib and DBus-GLib are already installed, more tests will be built, providing better coverage. The new tests can also be installed via ./configure --enable-installed-tests for system integration testing, if required. (fd.o #34570, Simon McVittie) Changes: • Consistently use atomic operations for the DBusConnection's refcount, fixing potential threading problems (fd.o #38005, Simon McVittie) • Don't use -Wl,--gc-sections by default: in practice the size decrease is small (300KiB on x86-64) and it frequently doesn't work in unusual toolchains. To optimize for minimum installed size, you should benchmark various possibilities for CFLAGS and LDFLAGS, and set the best flags for your particular toolchain at configure time. (fd.o #33466, Simon McVittie) • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD (fd.o #35880, Timothy Redaelli) • Use ln -fs to set up dbus for systemd, which should fix reinstallation when not using a DESTDIR (fd.o #37870, Simon McVittie) • Windows-specific changes: · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand) D-Bus 1.5.2 (2011-06-01) == The "Boar Hunter" release. Notes for distributors: This version of D-Bus no longer uses -fPIE by default. Distributions wishing to harden the dbus-daemon and dbus-launch-helper can re-enable this if their toolchain supports it reliably, via something like: ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro" or by using distribution-specific wrappers such as Debian's hardening-wrapper. Changes: • D-Bus Specification v0.17 · Reserve the extra characters used in signatures by GVariant (fd.o #34529, Simon McVittie) · Define the ObjectManager interface (fd.o #34869, David Zeuthen) • Don't force -fPIE: distributions and libtool know better than we do whether it's desirable (fd.o #16621, fd.o #27215; Simon McVittie) • Allow --disable-gc-sections, in case your toolchain offers the -ffunction-sections, -fdata-sections and -Wl,--gc-sections options but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie) • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato) • Ensure that maintainers upload documentation with the right permissions (fd.o #36130, Simon McVittie) • Don't force users of libdbus to be linked against -lpthread, -lrt (fd.o #32827, Simon McVittie) • Log system-bus activation information to syslog (fd.o #35705, Colin Walters) • Log messages dropped due to quotas to syslog (fd.o #35358, Simon McVittie) • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie) • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id (fd.o #35228, Lennart Poettering) • In the regression tests, don't report fds as "leaked" if they were open on startup (fd.o #35173, Simon McVittie) • Make dbus-monitor bail out if asked to monitor more than one bus, rather than silently using the last one (fd.o #26548, Will Thompson) • Clarify documentation (fd.o #35182, Simon McVittie) • Clean up minor dead code and some incorrect error handling (fd.o #33128, fd.o #29881; Simon McVittie) • Check that compiler options are supported before using them (fd.o #19681, Simon McVittie) • Windows: • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker) D-Bus 1.5.0 (2011-04-11) == The "you never know when you need to tow something from your giant flying shark" release. • D-Bus Specification v0.16 · Add support for path_namespace and arg0namespace in match rules (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie) · Make argNpath support object paths, not just object-path-like strings, and document it better (fd.o #31818, Will Thompson) • Let the bus daemon implement more than one interface (fd.o #33757, Simon McVittie) • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261, Roberto Guido) • Require user intervention to compile with missing 64-bit support (fd.o #35114, Simon McVittie) • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie) • Raise UnknownObject instead of UnknownMethod for calls to methods on paths that are not part of the object tree, and UnknownInterface for calls to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering) D-Bus 1.4.8 (2011-04-08) == The "It's like the beginning of a lobster" release. • Rename configure.in to configure.ac, and update it to modern conventions (fd.o #32245; Javier Jardón, Simon McVittie) • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496, Anders Kaseorg) • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add --disable-x11-autolaunch configure option to prevent it altogether in embedded environments (fd.o #19997, NB#219964; Simon McVittie) • Install the documentation, and an index for Devhelp (fd.o #13495, Debian #454142; Simon McVittie, Matthias Clasen) • If checks are not disabled, check validity of string-like types and booleans when sending them (fd.o #16338, NB#223152; Simon McVittie) • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly errors to dbus-shared.h (fd.o #34527, Lennart Poettering) • Break up a huge conditional in config-parser so gcov can produce coverage data (fd.o #10887, Simon McVittie) • List which parts of the Desktop Entry specification are applicable to .service files (fd.o #19159, Sven Herzberg) • Don't suppress service activation if two services have the same Exec= (fd.o #35750, Colin Walters) • Windows: · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h (Andre Heinecke) · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation (fd.o #32805, Mark Brand) D-Bus 1.4.6 (2010-02-17) == The "1, 2, miss a few, 99, 100" release. • Remove unfinished changes intended to support GTest-based tests, which were mistakenly included in 1.4.4 D-Bus 1.4.4 (2010-02-17) == • Switch back to using even micro versions for stable releases; 1.4.1 should have been called 1.4.2, so skip that version number • Don't leave bad file descriptors being watched when spawning processes, which could result in a busy-loop (fd.o #32992, NB#200248; possibly also LP#656134, LP#680444, LP#713157) • Check for MSG_NOSIGNAL correctly • Fix failure to detect abstract socket support (fd.o #29895) • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL (fd.o #32262, NB#180486) • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262, fd.o #33128, fd.o #33277, fd.o #33126, NB#180486) • Avoid possible symlink attacks in /tmp during compilation (fd.o #32854) • Tidy up dead code (fd.o #25306, fd.o #33128, fd.o #34292, NB#180486) • Improve gcc malloc annotations (fd.o #32710) • If the system bus is launched via systemd, protect it from the OOM killer • Documentation improvements (fd.o #11190) • Avoid readdir_r, which is difficult to use correctly (fd.o #8284, fd.o #15922, LP#241619) • Cope with invalid files in session.d, system.d (fd.o #19186, Debian #230231) • Don't distribute generated files that embed our builddir (fd.o #30285, fd.o #34292) • Raise the system bus's fd limit to be sufficient for its configuration (fd.o #33474, LP#381063) • Fix syslog string processing • Ignore -Waddress • Remove broken gcov parsing code and --enable-gcov, and replace them with lcov HTML reports and --enable-compiler-coverage (fd.o #10887) • Windows: · avoid live-lock in Windows CE due to unfair condition variables • OpenBSD: · support credentials-passing (fd.o #32542) • Solaris: · opt-in to thread safety (fd.o #33464) D-Bus 1.4.1 (20 December 2010) == • Fix for CVE-2010-4352: sending messages with excessively-nested variants can crash the bus. The existing restriction to 64-levels of nesting previously only applied to the static type signature; now it also applies to dynamic nesting using variants. Thanks to Rémi Denis-Courmont for discoving this issue. • OS X portability fixes, including launchd support. • Windows autolaunch improvements. • Various bug fixes. D-Bus 1.4.0 (6 Sep 2010) == - systemd hookup D-Bus 1.3.1 (23 June 2010) == - New standardized PropertiesChanged signal in the properties interface - Various portability fixes, in particular to Windows platforms - Support forking bus services, for compatibility D-Bus 1.3.0 (29 July 2009) == - ability for dbus-send to send to any bus (--address) - file descriptor passing on Unix socket transports - use of GCC atomic intrinsics for better processor support (requires -march=i486 or above for x86 compilation) - thread-safe FD_CLOEXEC setting on recent Linux kernels (2.6.24-27 and up) and glibc (2.9 for pipe2 and 2.10 for accept4) - feature negotiation in the bus daemon
