dbus 1.13.0 (UNRELEASED)
========================

This is a new development branch for the adventurous, and comes with a
risk of regressions. OS distributions should stay with the 1.12.x branch,
unless they can commit to following the 1.13.x branch until it reaches
a 1.14.0 stable release at an unspecified point in the future.

Behaviour changes:

 DBusServer (and hence the dbus-daemon) no longer accepts usernames
  (login names) for the recommended EXTERNAL authentication mechanism,
  only numeric user IDs or the empty string. This is not believed to
  affect real D-Bus clients in practice, because most D-Bus clients
  send numeric user IDs: the only known client implementation that
  sends usernames is dbus-java, and that only when run on a system
  where the com.sun.security.auth.module.UnixSystem.getUid() method is
  not available. (fd.o #104588, Simon McVittie)

• GLib >= 2.40 is required if full test coverage is enabled.
• [Linux] libselinux >= 2.0.86 is required if SELinux support is
  enabled.
• [Unix] dbus now requires an <inttypes.h> that defines C99 constants
  such as PRId64 and PRIu64, except when building for Windows.
• [Autotools] Building from git (but not from tarballs) with Autotools
  now requires macros from the GNU Autoconf Archive.

• [CMake] Builds done using CMake now require CMake 3.0.2.
153 154 155 156 157 158 159 160 161 162 163 164 165 166

Build-time configuration changes:

• Expat is now found using pkg-config. See the release notes for
  1.11.14.
• The --disable-compiler-optimisations and --enable-compiler-coverage
  options no longer exist.  See the release notes for 1.11.4 and 1.11.8.
• [Unix] The --enable-abstract-sockets and --disable-abstract-sockets
  options no longer exist. See the release notes for 1.11.20.
• [Unix] Flag files in /var/run/console/${username} are no longer
  checked for at_console by default. See the release notes for 1.11.18.
• [Unix, Cygwin] Init scripts are no longer provided by upstream dbus,
  and packagers will now need to add these downstream (most already do).
  See the release notes for 1.11.18.

• [Unix] The process ID file no longer has a different default location
  on Red Hat derivatives. See the release notes for 1.11.18.
• [Unix] ${runstatedir} is now independent of ${localstatedir} with
  recent Autotools versions. See the release notes for 1.11.16.

• [Windows] The WINDRES variable is no longer used. See the release
  notes for 1.11.22.

Deprecations:

• Eavesdropping is officially deprecated in favour of BecomeMonitor.
  See the release notes for spec version 0.31 (in dbus 1.11.14).
• [Unix] Flag files in /var/run/console/${username} are deprecated.
  See the release notes for 1.11.18.

New APIs:

• <allow> and <deny> rules in dbus-daemon configuration can now
  include send_broadcast="true", send_broadcast="false",
  max_unix_fds="N", min_unix_fds="N" (for some integer N).
  See the release notes for 1.11.18.
• dbus_try_get_local_machine_id() is like
  dbus_get_local_machine_id(), but returns a DBusError.
• New APIs around DBusMessageIter to simplify cleanup.
  See the release notes for 1.11.16.
• The message bus daemon now implements the standard Introspectable,
  Peer and Properties interfaces. See the release notes for
  dbus 1.11.14 and spec version 0.31.
• DTDs for introspection XML and bus configuration are installed.
• dbus can be compiled to be relocatable, making it more suitable for
  binary bundling with other software. On Windows, this is on by
  default.
• [Unix] A new unix:dir=… address family resembles unix:tmpdir=… but
  never uses Linux abstract sockets, which is advantageous for
  containers. On non-Linux it is equivalent to unix:tmpdir=….
  See the release notes for dbus 1.11.14 and spec version 0.31.
• [Unix] New option "dbus-launch --exit-with-x11".
• [Unix] Session managers can create transient .service files in
  $XDG_RUNTIME_DIR/dbus-1/services. See the release notes for 1.11.12.
• [Unix] A sysusers.d snippet can create the messagebus user on-demand.

Miscellaneous behaviour changes:

• [Unix] The session bus now logs to syslog if it was started by
  dbus-launch.
• [Unix] Internal warnings are logged to syslog if configured.

• On Windows, embed a manifest in dbus-update-activation-environment.exe
  so that the heuristics used for UAC do not assume it needs elevated
  privileges due to its name containing "update"

The “vampire conquistador” release.

311 312 313 314 315 316 317 318 319 320 321 322 323
Build-time configuration changes:

• By default, dbus-daemon on Unix no longer checks for flag files
  /var/run/console/${username} created by the obsolete pam_console and
  pam_foreground PAM modules when deciding whether ${username} is
  currently at the console. The old default behaviour can be restored
  by specifying --with-console-auth-dir=/var/run/console in the
  recommended Autotools build system, or
  -DDBUS_CONSOLE_AUTH_DIR=/var/run/console in CMake. This feature is
  now deprecated, and will be removed in dbus 1.13 unless feedback via
  fd.o #101629 indicates that this would be problematic.
  (fd.o #101629, Simon McVittie)

324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348
• LSB-style init scripts for Red Hat and Slackware, and a non-LSB init
  script for Cygwin, are no longer provided in the upstream dbus
  source. We recommend that distributors who support non-systemd service
  management should maintain their own init scripts or other service
  manager integration as part of their downstream packaging, similar to
  the way Debian distributes a Debian-specific LSB init script for dbus.

  The systemd unit continues to be maintained as part of the upstream
  dbus source, because it receives regular testing and maintenance.

  (fd.o #101706, Simon McVittie)

• The process ID file created by the system bus is no longer influenced
  by the --with-init-scripts=redhat configure option or the presence of
  /etc/redhat-release at build time. If your OS's init script or other
  service management relies on the Red Hat-style pid file, it can be
  restored by specifying --with-system-pid-file=/run/messagebus.pid at
  configure time or using the <pidfile> directive in bus configuration.

  Note that the upstream-supplied systemd unit runs dbus-daemon with
  the --nopidfile option, so it does not normally write a pid file,
  regardless of whether the OS is Red-Hat-derived or not.

Enhancements:

 <allow> and <deny> rules in dbus-daemon configuration can now

 <allow> and <deny> rules can now be configured to apply only to
  messages with or without Unix file descriptors attached. This would
  typically be used in rules like these:
  <allow send_destination="..." max_unix_fds="0"/>
  <deny send_destination="..." min_unix_fds="1"/>
  <deny receive_sender="..." min_unix_fds="1"/>
  but can also be used to set a nonzero upper limit on the number of
  file descriptors:
  <allow send_destination="..." max_unix_fds="4"/>

 On Unix platforms, the DBUS_COOKIE_SHA1 authentication mechanism
  now respects the HOME environment variable on the client side, and
  on the server side when the uid attempting to connect is the same
  as the uid of the server. This allows the automated tests to pass in
  environments where the user's "official" home directory in /etc/passwd
  is nonexistent, such as Debian autobuilders.

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.

Build-time configuration changes:

 We now use pkg-config to find libexpat in Autotools builds. This requires
  Expat 2.1.0 (March 2012) or later. In particular, this should remove the
  need to configure with LDFLAGS=-L/usr/local/lib on OpenBSD, which can
  itself cause compilation failures.

  As with all pkg-config-based configure checks, you can use
  PKG_CONFIG_PATH=/whatever/lib/pkgconfig to find expat.pc in a
  non-standard prefix, or EXPAT_CFLAGS="-I/whatever/include" and
  EXPAT_LIBS="-L/whatever/lib -lexpat" to avoid needing a .pc file
  at all.

Behaviour changes:

 Previously, /etc/machine-id could be copied to /var/lib/dbus/machine-id
  as a side-effect of a sufficiently privileged process merely reading the
  machine ID. It is no longer copied as a side-effect of reading.
  Running dbus-uuidgen --ensure, which should be done after installing dbus,
  continues to copy /etc/machine-id to /var/lib/dbus/machine-id if the
  former exists and the latter does not.
  (fd.o #101257, Simon McVittie)

 The undocumented Verbose interface, and the GetAllMatchRules method on
  the undocumented Stats interface, must now be used via the object path
  /org/freedesktop/DBus. Previously, they existed on all object paths.
  (fd.o #101257, Simon McVittie)

503 504 505 506 507 508 509
 AddMatch() with a match rule containing eavesdrop='true' will now fail
  unless called by either the same user as the dbus-daemon, or Unix uid 0
  (root), matching the restrictions applied to the newer BecomeMonitor()
  method. On the session bus this has no practical effect. On the system
  bus this will prevent certain configurations that already did not
  work well in practice. (fd.o #101567, Simon McVittie)

• dbus can be configured with --enable-relocation when building with
  Autotools, or with -DDBUS_RELOCATABLE=ON when building with cmake,
  to make the pkg-config metadata relocatable. This is useful for
  non-standard prefixes, and in particular for Windows installations.
  However, it is not recommended for system-wide installations into
  /usr, because it interferes with pkg-config's ability to filter out
  compiler default linker directories.

  With Autotools, the default is --enable-relocation when building
  for Windows or --disable-relocation otherwise. With CMake, the default
  is -DDBUS_RELOCATABLE=ON.

The “darkly whimsical” 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.

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
1200 1201
 org.freedesktop.DBus.Verbose interface (not normally compiled)
  · toggles the effect of DBUS_VERBOSE

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.

  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 <auth> element. This configuration
  is not recommended.
