1 D-Bus 1.5.4 (UNRELEASED)
4 Security (local denial of service):
6 • Byte-swap foreign-endian messages correctly, preventing a long-standing
7 local DoS if foreign-endian messages are relayed through the dbus-daemon
8 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
9 (fd.o #38120, Debian #629938, no CVE number yet; Simon McVittie)
13 • The constant to use for an infinite timeout now has a name,
14 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
15 which can be used for source compatibility with older versions of libdbus.
17 • If GLib and DBus-GLib are already installed, more tests will be built,
18 providing better coverage. They can be installed via
19 ./configure --enable-installed-tests
20 for system integration testing, if required. (fd.o #34570, Simon McVittie)
24 • Consistently use atomic operations for the DBusConnection's refcount
25 (fd.o #38005, Simon McVittie)
27 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
28 small (300KiB on x86-64) and it frequently doesn't work in unusual
29 toolchains. To optimize for minimum installed size, you should benchmark
30 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
31 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
33 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
34 (fd.o #35880, Timothy Redaelli)
36 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
37 when not using a DESTDIR (fd.o #37870, Simon McVittie)
39 • Windows-specific changes:
40 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
42 D-Bus 1.5.2 (2011-06-01)
45 The "Boar Hunter" release.
47 Notes for distributors:
49 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
50 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
51 toolchain supports it reliably, via something like:
53 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
55 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
59 • D-Bus Specification v0.17

61 (fd.o #34529, Simon McVittie)
62 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
63 • Don't force -fPIE: distributions and libtool know better than we do whether
64 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
65 • Allow --disable-gc-sections, in case your toolchain offers the
66 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
67 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
68 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
69 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
70 • Ensure that maintainers upload documentation with the right permissions
71 (fd.o #36130, Simon McVittie)
72 • Don't force users of libdbus to be linked against -lpthread, -lrt
73 (fd.o #32827, Simon McVittie)

76 • Log messages dropped due to quotas to syslog (fd.o #35358,
78 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
79 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
80 (fd.o #35228, Lennart Poettering)
81 • In the regression tests, don't report fds as "leaked" if they were open
82 on startup (fd.o #35173, Simon McVittie)
83 • Make dbus-monitor bail out if asked to monitor more than one bus,
84 rather than silently using the last one (fd.o #26548, Will Thompson)
85 • Clarify documentation (fd.o #35182, Simon McVittie)

102 · Make argNpath support object paths, not just object-path-like strings,
103 and document it better (fd.o #31818, Will Thompson)
104 • Let the bus daemon implement more than one interface (fd.o #33757,
106 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
108 • Require user intervention to compile with missing 64-bit support
109 (fd.o #35114, Simon McVittie)
110 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
111 • Raise UnknownObject instead of UnknownMethod for calls to methods on
112 paths that are not part of the object tree, and UnknownInterface for calls
113 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
115 D-Bus 1.4.8 (2011-04-08)
118 The "It's like the beginning of a lobster" release.

122 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,

126 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
127 • Install the documentation, and an index for Devhelp (fd.o #13495,
128 Debian #454142; Simon McVittie, Matthias Clasen)
129 • If checks are not disabled, check validity of string-like types and
130 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
131 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
132 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
133 • Break up a huge conditional in config-parser so gcov can produce coverage
134 data (fd.o #10887, Simon McVittie)
135 • List which parts of the Desktop Entry specification are applicable to
136 .service files (fd.o #19159, Sven Herzberg)
137 • Don't suppress service activation if two services have the same Exec=
138 (fd.o #35750, Colin Walters)
140 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
142 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
143 (fd.o #32805, Mark Brand)
145 D-Bus 1.4.6 (2010-02-17)
148 The "1, 2, miss a few, 99, 100" release.

151 which were mistakenly included in 1.4.4
153 D-Bus 1.4.4 (2010-02-17)
156 • Switch back to using even micro versions for stable releases; 1.4.1
157 should have been called 1.4.2, so skip that version number
158 • Don't leave bad file descriptors being watched when spawning processes,
159 which could result in a busy-loop (fd.o #32992, NB#200248; possibly

161 • Check for MSG_NOSIGNAL correctly

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