4 This is a bugfix release, it fixes one DoS (100% CPU Usage) and a regression
7 * Revert previous patch to check nlmsg_pid as it is bogus and breaks in
8 many cases, notably when using NetworkManager (Closes: #72)
9 * Replace with new SO_PASSCRED-based check of the sending UID, which
10 seems to work better (Closes: #72)
11 * Handle some errors in libdns_sd more gracefully the way the real
12 libdns_sd does (Closes: #64)
13 * Apply fix for Linux 2.6.19+ where IFA_RTA / IFLA_RTA is no longer
15 * Fix doxygen comments for avahi watch, thanks to tedp (Closes: #77)
16 * Make d-bus version detection work for >= 1.0 (Closes: #71)
17 * Dont dbus_connection_close on shared dbus connections (Closes: #68)

19 * Fix bogus assertion in client-publish-service.c example
20 * Mild fix to some doxygen docs for avahi-common/address.h
21 * Fix passing in custom priviledged group (previously ignored setting)
24 This release is backwards compatible with Avahi 0.6.x with x < 16.
29 This is a bugfix release, this bug is potentially security sensitive
31 * Check that netlink messages actually originate from the kernel
32 and not another process.
33 * Fix build on NetBSD (thanks to Daniel S. Haischt)
34 * Fix dbus_service_browser not setting AVAHI_LOOKUP_RESULT_OUR_OWN.
36 This release is backwards compatible with Avahi 0.6.x with x < 15.
41 This release fixes some bugs and includes a new component.
45 * Add new daemon "avahi-autoipd" which is an implementation of
46 IPv4LL as defined in RFC3927, a technology for assigning link-local IP
47 addresses without DHCP server. The same functionality has been available on
48 Windows under the name APIPA. While it is not the first implemenatation of
49 this technology for Free operating systems it is clearly the most powerful
50 and hopefully even the most secure. (Because it chroot()s and drops
51 priviliges and suchlike) For more information, especially about packaging
52 this new tool for distributions, please make sure to read:
53 http://avahi.org/wiki/AvahiAutoipd
54 and of course the man page included in the tarball. For the rationale for
55 adding this program to the Avahi toolset please read this mailing list
57 http://lists.freedesktop.org/archives/avahi/2006-September/000863.html
58 * Fix a segfault in the code handling static host name registrations
59 * Add a few new entries to the service type database
61 * Documentation updates
62 * Fix service type database building on Solaris
63 * Make use of newer D-Bus APIs
64 * Fix random seed initialization
65 * Install SFTP static service file by default
66 * Other minor code cleanups
68 This release is backwards compatible with Avahi 0.6.x with x < 14.
70 Please note that this version doesn't compile on NetBSD, patches
73 Please note that avahi-autoipd is available on Linux only for
74 now. Patches welcome. It is recommended to pass --disable-autoipd to
75 "configure" on non-Linux operating systems, otherwise the build will
81 This release fixes some bugs and includes minor enhancements.
84 * Add a new D-Bus method for changing the mDNS host name during
85 runtime. This functionality is only available to members of the
86 UNIX group "netdev", which is the same access group that is
87 enforced by GNOME's NetworkManager daemon. Since NM will probably
88 be the most prominent user of this new method, we decided to limit
89 access to the same group. The access group can be set by passing
90 --with-avahi-priv-access-group= to "configure". If you need more
91 sophisticated access control you can freely edit
92 /etc/dbus/system.d/avahi-dbus.conf.
93 * Add a new utility "avahi-set-host-name" which is a command line
94 wrapper around the aforementioned SetHostName() method.
95 * Bonjour API compatibility library:
96 * Implement DNSServiceUpdateRecord()
97 * Allow passing NULL as callback function for
99 * Implement subtype registration in DNSServiceRegister() in a
100 way that is compatible with Bonjour.
101 * Update to newer copy of dns_sd.h
102 * If the host name changes update names of static services wich
104 * Don't build documentation about embedding the Avahi mDNS stack into
105 other programs by default. This is a feature used only by embedded
106 developers. Pass --enable-core-docs to "configure" to enable
107 building these docs, like in Avahi <= 0.6.12.
108 * Build Qt documentation only when Qt support is enabled in
109 the configuration. Same for GLib.
110 * Change algorithm used to find a new host name on conflict. In
111 Avahi <= 0.6.12 a conflicting host name of "foobar" would be
112 changed to the new name "foobar2". With 0.6.13 "foobar-2" will be
113 picked instead. This follows Bonjour's behaviour and has the
114 advantage not confusing people with regular host names ending in
116 * Don't disable all static services when SIGHUP is recieved.
117 * Fix build when Avahi is configured without Gtk+ but with Python
119 * Fix build on MacOS X
120 * Support using Solaris DBM instead of gdbm for the service type
121 database. The latter is still recommended
122 * Minor other fixes and documentation updates
124 This release is backwards compatible with Avahi 0.6.x with x < 13.
129 This is a bugfix and general cleanups release.
132 * Compatibility with newer D-Bus releases (0.9x)
133 * Compatibility with DBUS builds with --disable-checks
134 * Fix an error in the DBUS event loop wrapping which
135 caused the avahi client libraries to dispatch some events
136 too late when used with D-BUS 0.62 and newer.
137 * avahi-daemon: fix a minor memory leak in the DBUS code.
138 * avahi-glib: some GLIB adapter cleanups
139 * avahi-dnsconfd: fix segfault when passing an invalid command
141 * avahi-test: portability patches for Solaris
142 * avahi-browse: flush STDOUT after each line, making it useful
144 * update service type database
146 This release is backwards compatible with Avahi 0.6.x with x < 12.
151 This is a bugfix and portability release.
155 * avahi-sharp: fix a fatal error in object disposal code
156 * add a few new entries to the servivce type database
157 * fix potential crash when the daemon shuts down
158 * compatibility with newer autoconf versions
160 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
161 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10.
166 This is mostly a bugfix release. Two of the bugs fixed are security
167 sensitive: a remote denial-of-service vulnerability and a buffer
168 overflow that can allow local users to become the 'avahi' user. We do
169 not consider either of them major security threats.
171 The DoS vulnerability can be exploited from a local network only. It
172 is not worth much, though, since mDNS can easily be flooded with
173 nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by
174 provoking a name conflict in perfect accordance with the specs.
176 The buffer overflow is hard to exploit remotely, only local users can
177 become the 'avahi' user. In addition the user is trapped inside a
178 chroot() environment (at least on Linux).
180 Anyhow, our security assessments are possibly as buggy as our
183 *** PLEASE UPDATE YOUR INSTALLATION ASAP! ***
186 * Fix a buffer overflow in avahi-core
187 * Refuse to process invalid UTF8 data
188 * Automatically reconnect to the DBUS if we're kicked. (Works only if
189 chroot() is disabled)
190 * Don't hit an assert() in the client libs when the Avahi daemon is
192 * Enumerate all service types in the database in the Service
193 Discovery Applet for Gnome
194 * Improve the Bonjour compatibility layer to make it survive
195 GnomeMeeting's broken usage
196 * Deal properly with local non-ASCII hostnames
197 * AMD64 and FreeBSD portability fixes
198 * Filter double DNS server entries in avahi-dnsconfd
199 * Fix a locking bug in avahi-sharp's EntryGroup.AddService()
200 * Ported to Solaris (incomplete)
201 * Add _airport._tcp to our service type database
203 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
204 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.8 and 0.6.9.

222 This release fixes some bugs and adds a few new features. Users of 0.6.7,
225 * Fix broken parsing of static hosts file
226 * Improve out-of-the-box Debian support
227 * Add configuration option to allow mDNS over POINTOPOINT links.
228 This is a potential security hole and YMMV. See man page for details.
229 * Create $(localstatedir)/run on installation
231 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
232 0.6.3, 0.6.4, 0.6.5, 0.6.6 and 0.6.7.
237 This release fixes some bugs and adds a few new features

240 * Work around kernel bugs regarding multicast group membership
241 * ia64 portability fixes
242 * Don't require X11 to run avahi-bookmarks
243 * API: Return AVAHI_ERR_IS_EMPTY when the user tries to commit an
245 * Improved Slackware and Fedora suppport
247 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,

267 0.6.3, 0.6.4 and 0.6.5.
272 This release fixes some bugs and adds a new API function.
274 * avahi-browse: properly show services that are removed from the
276 * fix build on bi-arch platforms, on GNU/kFreeBSD, on MIPS and
278 * add new API function avahi_nss_support() and DBUS function
279 IsNSSSupportAvailable() which may be used to detect whether
280 libc's gethostbyname() supports mDNS domain names.
281 * patch avahi-bookmarks to make use of
282 IsNSSSupportAvailable(). avahi-bookmarks will now generate links
283 with real hostnames instead of numeric IP addresses if mDNS support
284 is detected for gethostbyname().
285 * add init script for Mandriva Linux
286 * speed up avahi_client_free()
288 * install missing header thread-watch.h
289 * fix avahi-bookmarks to work with certain twisted versions
290 * fix record updating
291 * Use pkg-config's Requires.private directive where it makes sense
293 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,

310 A quick introduction how to use the new AvahiThreadedPool interface is
311 available in our Wiki:
313 http://avahi.org/wiki/RunningAvahiClientAsThread
318 This is a bugfix release. Everyone should update ASAP!
320 * avahi-sharp: make sure to append a trailing NUL byte to all C strings
321 * avahi-core: fix a double free() which occurs when wide area lookups timeout
323 This release is fully compatible with Avahi 0.6, 0.6.1 and 0.6.2.
328 This is mostly a bugfix release.
330 * Compatibility with DBUS 0.60 (Full compatibility with DBUS 0.3x and
332 * Fix introspection for some auxiliary DBUS objects
333 * Miscellaneous documentation updates
334 * Improve Autoconf support for detecting PTHREADS library
335 * Fix avahi-publish --help
336 * Workaround a DBUS limitation which might cause Avahi to die when a
337 user sends an empty TXT entry over DBUS
338 * Increase number of resolver/browser objects a DBUS client may create
339 * Remove fprintf() call in avahi_client_new()
342 This release is both up and downwards compatible with Avahi 0.6 and 0.6.1.
344 Avahi now has its own Domain (http://avahi.org) and a new Website!
346 And, most importantly, we now have a Logo:
347 http://avahi.org/chrome/site/avahi-trac.png
352 This is mostly a bugfix release.
354 * Fix a segfault when shutting down the daemon. Please note that this
355 issue was not security sensitive in any way but had the ugly side
356 effect that the daemon's PID file was not removed properly.
357 * Added init scripts for ArchLinux and FreeBSD
358 * Add DBUS API versioning through the new method GetAPIVersion()
359 * Build the HOWL compatibility library as "libhowl.so", instead of
360 "libavahi-compat-howl.so". This will help distributors to ensure
361 full API/ABI compatibility with HOWL out-of-the-box.
362 * Same for the Bonjour compatibility library
365 We encourage Linux users to update to libdaemon 0.10 since logging
366 does not work from a chroot() environment with older versions.
368 This release is fully API and ABI compatible with Avahi 0.6. This is
369 true for both the C libraries and the DBUS interface.
371 Packagers should read the new documentation file doc/COMPAT-LAYERS
372 which contains some information about maintaining full build system
373 compatibility in addition to ABI/API compatibility.

446 - Add option to generate links with hostnames instead of IPs
448 Avahi 0.2, the 'Dzień Dobry' release
449 ====================================
451 * Unfortunately this release broke the API/ABI of libavahi-client
452 with the following function removals
454 Removal of these functions may affect users of the 0.1 API
455 - avahi_service_resolver_block()
457 The following functions were simply for debugging information
458 and their removal should not affect anyone
459 - avahi_entry_group_get_dbus_path()
460 - avahi_domain_browser_get_dbus_path()
461 - avahi_service_type_browser_get_dbus_path()

468 * avahi-daemon will now ignore local IP addresses with the "link" scope
469 unless it is the only IP address on the interface.
470 * avahi-daemon will no longer fail to start if D-BUS is not
471 available (if configured with enable-dbus=warn)

479 * Fixed a typo in avahi-glib.pc that stopped programs using
480 the GLIB api from compiling correctly
481 * A critical bug in the reflector was fixed where it may go into a
482 state of constantly flooding queries out to the network.

496 * Fixed compilation and runtime issues on 64-bit distributions
500 Avahi 0.1, the "Guten Tag" release
501 ==================================
503 The Avahi team would like to announce the immediate availability of
504 Avahi 0.1 "Guten Tag".
506 Avahi is a fully LGPL framework for Multicast DNS Service Discovery.
507 It allows programs to publish and discover services and hosts
508 running on a local network with no specific configuration. For
509 example you can plug into a network and instantly find printers to
510 print to, files to look at and people to talk to.
512 Avahi is designed to be compatible with the mDNS/DNS-SD specification
513 and boasts the following features
515 * Fully open source and freely available under the LGPL
516 * Full IPv4 and IPv6 support
517 * An embeddable mDNS stack
518 * Dynamic adjustment to network reconfiguration
519 * Daemon with DBUS API for desktop applications
520 * C library to interface with the DBUS API
521 * Compatible with other mDNS/DNS-SD implementations such as
522 Howl and Apple Bonjour (previously Rendezvous)
523 * Ability to correctly "reflect" mDNS between two or more LAN segments
524 * Ability to configure DNS servers based on mDNS/DNS-SD published
525 information, a feature that is very usefull on IPv6
526 which has no other mechanism for this.
527 * Combined with nss-mdns, allows hostname lookup such as
528 'laptop.local' without the configuration of a DNS server.
529 http://0pointer.de/lennart/projects/nss-mdns/
530 * Easy integration into GLIB, GTK other mainloop applications.
531 * Documentation and examples of both developer APIs and utilities.
533 mDNS/DNS-SD is part of a larger set of specifications for easy
534 configuration of networking known as "ZeroConf"
535 (http://www.zeroconf.org/), with the aim of allowing you to plug into
536 a network and instantly be able to interact with it's services.
538 Avahi was designed to be a fully free implementation, and is
539 available under the LGPL. Many other implementations of the mDNS/DNS-SD
540 specification were previously non-free, restricting their use in many
541 platforms such as the GNOME desktop and many distributions.
543 While Avahi is a 0.1 release, we feel it is feature complete and
544 available for immediate use, developers can make use of the Avahi
545 client library to provide above mentioned functionality in their
548 We unfortunately do not have a logo yet! We would love if someone
549 could suggest ideas for a logo or even design us one. If you think
