Avahi 0.6.21 ============ This is an important bugfix release. * Make avahi-autoipd actually produce correct ARP packets (Identified and patched by Pauline Yeung) * Add FreeBSD kqueue support for watching /etc/avahi/services (Contributed by Marcus Clarke) * Use search domain from /etc/resolv.conf as additional browse domains. * No longer return a conflict error when two local applications register identical RRs. * Properly find alternative service/host names for very long names * DNS name compression fix (Sjoerd Simons) * Fedora init script order fix * Several fixes to make gcc produces less warnings * Minor documentation and build fixes This release is backwards compatible with Avahi 0.6.x with x < 21. Avahi 0.6.20 ============ This is a bugfix release and contains a fix for a low risk security vulnerability. * Fix a local DoS vulnerability, where an assert() could be hit by passing empty TXT data over D-Bus to the Avahi daemon. (Low Risk) * Solaris/dbm portability fixes * Close all open file descriptors when daemonizing. Is generally safer and fixes a few issues with broken init systems of several distributions. * avahi-autoipd: allow passing the path of the action script on the command line. * Several minor build fixes and other cleanups This release is backwards compatible with Avahi 0.6.x with x < 20. Avahi 0.6.19 ============ This is a bugfix release, but also adds a new component "avahi-ui-sharp". * Rename zssh/zvnc to bssh/bvnc to avoid a name collision with another free software tool, on request of the Debian developers. I hope this name change early in the life of bssh/bvnc won't be too difficult to handle by the distributors. * Add man page for bssh/bvnc * avahi-ui: fix segfault when browsing in empty domains * avahi-ui: allow GTK_RESPONSE_OK, _YES and _APPLY besides _ACCEPT as positive dialog response codes * avahi-ui-sharp: Add Mono/C# API wrapper for avahi-ui * Don't pick the first and the last 256 IP addresses from the IPV4LL range in avahi-autoipd, as required by RC3927 section 2.1 * No longer publish the Avahi service identification cookie anymore by default. It was a bad idea in the first place. A better replacement will hopefully be made available in Avahi eventually. * Properly set umask before writing to /var/lib/avahi-autoipd * Update .deskop files to work around KDE menu issue * Various build fixes and other minor fixes and updates This release is backwards compatible with Avahi 0.6.x with x < 19. Avahi 0.6.18 ============ This is a bugfix release, adds a few new features and includes a new component. * Add a new library libavahi-ui which contains a standard Gtk dialog for browsing for services, and a new tool "zssh" that makes use of it, which allows browsing for SSH and VNC servers and starts ssh or xvncviewer if one item is selected. * avahi-autoipd has been ported to FreeBSD (original patch from Bruce M Simpson) * Improve OpenBSD, Solaris, MacOS X compatibility * Linux inotify support for monitoring /etc/avahi/services/ and /etc/avahi/hosts for changes. (Original patch from "behanw") * Add the ability to dump the service type database from avahi-browse with the new option "-b". * Enable GCC stack smashing protection if available and working (Patch from tedp) * Improve compatibility with Bonjour's libdns_sd (patch from Chris Rivera) * Various updates to the service type database (based on patches from uws) * Fix a local DoS vulnerability (very low priority, all you can do is make Avahi hit an assert()); problem identified by "jamesh" * Fix a problem when constantly generating conflict events for an RR * Fix registration of very large RRs (original patch from Sjoerd Simons) * Various minor fixes This release is backwards compatible with Avahi 0.6.x with x < 18. Avahi 0.6.17 ============ This is a bugfix release. * Don't accept "localhost" as a local mDNS host name * Allow running avahi-bookmarks as CGI script * Improve libdns_sd compatibility * Stability: libdns_sd mutex locking order fix * Publish IPv6 addresses via IPv4 and vice versa * IA64 fixes * A lot of minor cleanups and fixes This release is backwards compatible with Avahi 0.6.x with x < 17. Avahi 0.6.16 ============ This is a bugfix release, it fixes one DoS (100% CPU Usage) and a regression from the last release * Revert previous patch to check nlmsg_pid as it is bogus and breaks in many cases, notably when using NetworkManager (Closes: #72) * Replace with new SO_PASSCRED-based check of the sending UID, which seems to work better (Closes: #72) * Handle some errors in libdns_sd more gracefully the way the real libdns_sd does (Closes: #64) * Apply fix for Linux 2.6.19+ where IFA_RTA / IFLA_RTA is no longer defined (Closes: #86) * Fix doxygen comments for avahi watch, thanks to tedp (Closes: #77) * Make d-bus version detection work for >= 1.0 (Closes: #71) * Dont dbus_connection_close on shared dbus connections (Closes: #68) * Fix potential endless loop in dns label unpacking code (Closes: #84) * Fix bogus assertion in client-publish-service.c example * Mild fix to some doxygen docs for avahi-common/address.h * Fix passing in custom priviledged group (previously ignored setting) (Closes: #85) This release is backwards compatible with Avahi 0.6.x with x < 16. Avahi 0.6.15 ============ This is a bugfix release, this bug is potentially security sensitive * Check that netlink messages actually originate from the kernel and not another process. * Fix build on NetBSD (thanks to Daniel S. Haischt) * Fix dbus_service_browser not setting AVAHI_LOOKUP_RESULT_OUR_OWN. This release is backwards compatible with Avahi 0.6.x with x < 15. Avahi 0.6.14 ============ This release fixes some bugs and includes a new component. Changes: * Add new daemon "avahi-autoipd" which is an implementation of IPv4LL as defined in RFC3927, a technology for assigning link-local IP addresses without DHCP server. The same functionality has been available on Windows under the name APIPA. While it is not the first implemenatation of this technology for Free operating systems it is clearly the most powerful and hopefully even the most secure. (Because it chroot()s and drops priviliges and suchlike) For more information, especially about packaging this new tool for distributions, please make sure to read: http://avahi.org/wiki/AvahiAutoipd and of course the man page included in the tarball. For the rationale for adding this program to the Avahi toolset please read this mailing list thread: http://lists.freedesktop.org/archives/avahi/2006-September/000863.html * Fix a segfault in the code handling static host name registrations * Add a few new entries to the service type database * s/D-?BUS/D-Bus/g * Documentation updates * Fix service type database building on Solaris * Make use of newer D-Bus APIs * Fix random seed initialization * Install SFTP static service file by default * Other minor code cleanups This release is backwards compatible with Avahi 0.6.x with x < 14. Please note that this version doesn't compile on NetBSD, patches welcome. Please note that avahi-autoipd is available on Linux only for now. Patches welcome. It is recommended to pass --disable-autoipd to "configure" on non-Linux operating systems, otherwise the build will fail. Avahi 0.6.13 ============ This release fixes some bugs and includes minor enhancements. Changes: * Add a new D-Bus method for changing the mDNS host name during runtime. This functionality is only available to members of the UNIX group "netdev", which is the same access group that is enforced by GNOME's NetworkManager daemon. Since NM will probably be the most prominent user of this new method, we decided to limit access to the same group. The access group can be set by passing --with-avahi-priv-access-group= to "configure". If you need more sophisticated access control you can freely edit /etc/dbus/system.d/avahi-dbus.conf. * Add a new utility "avahi-set-host-name" which is a command line wrapper around the aforementioned SetHostName() method. * Bonjour API compatibility library: * Implement DNSServiceUpdateRecord() * Allow passing NULL as callback function for DNSServiceRegister() * Implement subtype registration in DNSServiceRegister() in a way that is compatible with Bonjour. * Update to newer copy of dns_sd.h * If the host name changes update names of static services wich contain wildcards. * Don't build documentation about embedding the Avahi mDNS stack into other programs by default. This is a feature used only by embedded developers. Pass --enable-core-docs to "configure" to enable building these docs, like in Avahi <= 0.6.12. * Build Qt documentation only when Qt support is enabled in the configuration. Same for GLib. * Change algorithm used to find a new host name on conflict. In Avahi <= 0.6.12 a conflicting host name of "foobar" would be changed to the new name "foobar2". With 0.6.13 "foobar-2" will be picked instead. This follows Bonjour's behaviour and has the advantage not confusing people with regular host names ending in digits. * Don't disable all static services when SIGHUP is recieved. * Fix build when Avahi is configured without Gtk+ but with Python support * Fix build on MacOS X * Support using Solaris DBM instead of gdbm for the service type database. The latter is still recommended * Minor other fixes and documentation updates This release is backwards compatible with Avahi 0.6.x with x < 13. Avahi 0.6.12 ============ This is a bugfix and general cleanups release. Changes: * Compatibility with newer D-Bus releases (0.9x) * Compatibility with DBUS builds with --disable-checks * Fix an error in the DBUS event loop wrapping which caused the avahi client libraries to dispatch some events too late when used with D-BUS 0.62 and newer. * avahi-daemon: fix a minor memory leak in the DBUS code. * avahi-glib: some GLIB adapter cleanups * avahi-dnsconfd: fix segfault when passing an invalid command line option * avahi-test: portability patches for Solaris * avahi-browse: flush STDOUT after each line, making it useful in shell scripts. * update service type database This release is backwards compatible with Avahi 0.6.x with x < 12. Avahi 0.6.11 ============ This is a bugfix and portability release. Changes: * Ported to Solaris * avahi-sharp: fix a fatal error in object disposal code * add a few new entries to the servivce type database * fix potential crash when the daemon shuts down * compatibility with newer autoconf versions This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2, 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10. Avahi 0.6.10 ============ This is mostly a bugfix release. Two of the bugs fixed are security sensitive: a remote denial-of-service vulnerability and a buffer overflow that can allow local users to become the 'avahi' user. We do not consider either of them major security threats. The DoS vulnerability can be exploited from a local network only. It is not worth much, though, since mDNS can easily be flooded with nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by provoking a name conflict in perfect accordance with the specs. The buffer overflow is hard to exploit remotely, only local users can become the 'avahi' user. In addition the user is trapped inside a chroot() environment (at least on Linux). Anyhow, our security assessments are possibly as buggy as our code. Hence: *** PLEASE UPDATE YOUR INSTALLATION ASAP! *** Changes: * Fix a buffer overflow in avahi-core * Refuse to process invalid UTF8 data * Automatically reconnect to the DBUS if we're kicked. (Works only if chroot() is disabled) * Don't hit an assert() in the client libs when the Avahi daemon is terminated * Enumerate all service types in the database in the Service Discovery Applet for Gnome * Improve the Bonjour compatibility layer to make it survive GnomeMeeting's broken usage * Deal properly with local non-ASCII hostnames * AMD64 and FreeBSD portability fixes * Filter double DNS server entries in avahi-dnsconfd * Fix a locking bug in avahi-sharp's EntryGroup.AddService() * Ported to Solaris (incomplete) * Add _airport._tcp to our service type database This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2, 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.8 and 0.6.9. Avahi 0.6.9 =========== This release fixes some bugs and includes minor enhancements. * Don't allow registration of address records with invalid host names * Clean up argument validity checking for AvahiHostNameResolver and AvahiAddressResolver * Fix Avahi builds without DBUS This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2, 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7 and 0.6.8. Avahi 0.6.8 =========== This release fixes some bugs and adds a few new features. Users of 0.6.7, please update ASAP! * Fix broken parsing of static hosts file * Improve out-of-the-box Debian support * Add configuration option to allow mDNS over POINTOPOINT links. This is a potential security hole and YMMV. See man page for details. * Create $(localstatedir)/run on installation This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2, 0.6.3, 0.6.4, 0.6.5, 0.6.6 and 0.6.7. Avahi 0.6.7 =========== This release fixes some bugs and adds a few new features * Add static hosts name mappings * Work around kernel bugs regarding multicast group membership * ia64 portability fixes * Don't require X11 to run avahi-bookmarks * API: Return AVAHI_ERR_IS_EMPTY when the user tries to commit an empty entry group. * Improved Slackware and Fedora suppport This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2, 0.6.3, 0.6.4, 0.6.5 and 0.6.6. Avahi 0.6.6 =========== This release fixes some bugs and includes some documentation updates * Add a bunch of new types to the service type database * Return errors of avahi_entry_group_commit() properly * Many doxygen documentation improvements * Fix destruction of AvahiEntryGroup objects using avahi_entry_group_free(). * Don't allow commiting of empty entry groups * Use a little less memory in avahi-qt * Don't accept empty TXT strings * Update example "client-publish-service.c" to show how to modify an existing service This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2, 0.6.3, 0.6.4 and 0.6.5. Avahi 0.6.5 =========== This release fixes some bugs and adds a new API function. * avahi-browse: properly show services that are removed from the network * fix build on bi-arch platforms, on GNU/kFreeBSD, on MIPS and for non-DBUS builds * add new API function avahi_nss_support() and DBUS function IsNSSSupportAvailable() which may be used to detect whether libc's gethostbyname() supports mDNS domain names. * patch avahi-bookmarks to make use of IsNSSSupportAvailable(). avahi-bookmarks will now generate links with real hostnames instead of numeric IP addresses if mDNS support is detected for gethostbyname(). * add init script for Mandriva Linux * speed up avahi_client_free() * man page updates * install missing header thread-watch.h * fix avahi-bookmarks to work with certain twisted versions * fix record updating * Use pkg-config's Requires.private directive where it makes sense This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2, 0.6.3 and 0.6.4. Avahi 0.6.4 =========== This is a bugfix release and adds a new event loop implementation to avahi-common's public interface. * avahi-common: add new AvahiThreadedPool event loop implementation * avahi-sharp: compatibility with newer mono versions * avahi-publish-service: don't ignore the port number specified * avahi-sharp: correct some flags definitions This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2 and 0.6.3. A quick introduction how to use the new AvahiThreadedPool interface is available in our Wiki: http://avahi.org/wiki/RunningAvahiClientAsThread Avahi 0.6.3 =========== This is a bugfix release. Everyone should update ASAP! * avahi-sharp: make sure to append a trailing NUL byte to all C strings * avahi-core: fix a double free() which occurs when wide area lookups timeout This release is fully compatible with Avahi 0.6, 0.6.1 and 0.6.2. Avahi 0.6.2 =========== This is mostly a bugfix release. * Compatibility with DBUS 0.60 (Full compatibility with DBUS 0.3x and 0.5 is retained) * Fix introspection for some auxiliary DBUS objects * Miscellaneous documentation updates * Improve Autoconf support for detecting PTHREADS library * Fix avahi-publish --help * Workaround a DBUS limitation which might cause Avahi to die when a user sends an empty TXT entry over DBUS * Increase number of resolver/browser objects a DBUS client may create * Remove fprintf() call in avahi_client_new() * Other minor fixes This release is both up and downwards compatible with Avahi 0.6 and 0.6.1. Avahi now has its own Domain (http://avahi.org) and a new Website! And, most importantly, we now have a Logo: http://avahi.org/chrome/site/avahi-trac.png Avahi 0.6.1 =========== This is mostly a bugfix release. * Fix a segfault when shutting down the daemon. Please note that this issue was not security sensitive in any way but had the ugly side effect that the daemon's PID file was not removed properly. * Added init scripts for ArchLinux and FreeBSD * Add DBUS API versioning through the new method GetAPIVersion() * Build the HOWL compatibility library as "libhowl.so", instead of "libavahi-compat-howl.so". This will help distributors to ensure full API/ABI compatibility with HOWL out-of-the-box. * Same for the Bonjour compatibility library * Other fixes We encourage Linux users to update to libdaemon 0.10 since logging does not work from a chroot() environment with older versions. This release is fully API and ABI compatible with Avahi 0.6. This is true for both the C libraries and the DBUS interface. Packagers should read the new documentation file doc/COMPAT-LAYERS which contains some information about maintaining full build system compatibility in addition to ABI/API compatibility. Avahi 0.6, the "Goddag" release =============================== * Support for (read-only) wide area support. (i.e. DNS-SD over unicast DNS) * Ported to FreeBSD, NetBSD, Darwin/MacOSX and to some extent OpenBSD * Portability fixes for ARM CPUs * Compatibility layers for the HOWL and Bonjour APIs * Support for registering/browsing arbitrary records * Proper support for DNS-SD service subtypes * Native C implementations of the client utilities * Now passes the Bonjour conformance test suite without any exceptions * "Passive observation of failures" * chroot() support * Many traffic reduction improvements * Bugfixes, cleanups This release is not API/ABI compatible with Avahi 0.5. Please see docs/API-CHANGES-0.6 for a rough overview over the changes. Avahi 0.5.2 =========== * Bug fix release. * Fix browing in QT applications (was totally broken) * Minor documentation update. Avahi 0.5.1 =========== * This is a bug fix release, before the big changes coming in 0.6 * Fix reporting of the NO_DAEMON error * Fix commit throttling algorithm for entry groups * Fix counting of the number of resources in an entry group Avahi 0.5, the 'Bom Dia' release ================================ * New Mono bindings, allowing you to use Avahi from any CLI language such as C# * Attempt auto-detection of the D-BUS system bus address * Include a 'cookie' in all published records which allows us to reliably determine if a service is the same as another. * Add API to determine if services are local * Better support for threading with AvahiSimplePoll * Add some new StringList functions to help binding to it in other languages * Various build and run-time bug fixes Avahi 0.4, the 'Hyvää päivää' release ===================================== * Renamed the include dirs for the Qt bindings to include the version number, as they may diverge in future. * Fix a critical bug in avahi-daemon triggered by configuring an interface with various DHCP clients when you have no other active addresses which caused avahi-daemon to abort. * Move to using python-gdbm exclusivly for the service type database. * Add support for SUSE * Various fixes to the build system Avahi 0.3, the 'Buenos Días' release ==================================== * New integration library for QT main-loop applications. * Fix a crash in avahi-dnsconfd * Documentation Updates * Fix building when you don't want Python DBUS or GTK * avahi-bookmarks - Add new help option - Fix handling of paths not starting with a / - You can now specify the port and IP to bind to - Add option to generate links with hostnames instead of IPs Avahi 0.2, the 'Dzień Dobry' release ==================================== * Unfortunately this release broke the API/ABI of libavahi-client with the following function removals Removal of these functions may affect users of the 0.1 API - avahi_service_resolver_block() The following functions were simply for debugging information and their removal should not affect anyone - avahi_entry_group_get_dbus_path() - avahi_domain_browser_get_dbus_path() - avahi_service_type_browser_get_dbus_path() - avahi_service_browser_get_dbus_path() Note that while the libavahi-client API changed slightly, the DBUS API itself has only had additions and no existing definitions have changed. * avahi-daemon will now ignore local IP addresses with the "link" scope unless it is the only IP address on the interface. * avahi-daemon will no longer fail to start if D-BUS is not available (if configured with enable-dbus=warn) * Fixed a potential crasher when resolving things in libavahi-core. * New example demonstrating integration into glib applications * Addtion of a set of convenience functions for AvahiStringList avahi_string_list_find() avahi_string_list_get_pair() avahi_string_list_add_pair() avahi_string_list_add_pair_arbitrary() * Fixed a typo in avahi-glib.pc that stopped programs using the GLIB api from compiling correctly * A critical bug in the reflector was fixed where it may go into a state of constantly flooding queries out to the network. * Introduced new asynchronous resolver API * libavahi-client gained an API for resolving HostNames and Addresses in addition to the ServiceResolver provided in 0.1 * Added support for Arch and Gentoo linux distributions. * Allowed configuration on non-supported distributions * Fixed a critical bug where you cannot use more than one AvahiClient or use it in an application already using D-BUS * Fixed assembly of empty string lists to RFC compliant TXT records * Added a new service type description database with human understandable descriptions of services with translations. * Fixed various minor memory corruption bugs * Fixed an issue where Avahi might think it encountered a conflict if the process or machine has been suspended * Fixed compilation and runtime issues on 64-bit distributions * ... * PROFIT!!! Avahi 0.1, the "Guten Tag" release ================================== The Avahi team would like to announce the immediate availability of Avahi 0.1 "Guten Tag". Avahi is a fully LGPL framework for Multicast DNS Service Discovery. It allows programs to publish and discover services and hosts running on a local network with no specific configuration. For example you can plug into a network and instantly find printers to print to, files to look at and people to talk to. Avahi is designed to be compatible with the mDNS/DNS-SD specification and boasts the following features * Fully open source and freely available under the LGPL * Full IPv4 and IPv6 support * An embeddable mDNS stack * Dynamic adjustment to network reconfiguration * Daemon with DBUS API for desktop applications * C library to interface with the DBUS API * Compatible with other mDNS/DNS-SD implementations such as Howl and Apple Bonjour (previously Rendezvous) * Ability to correctly "reflect" mDNS between two or more LAN segments * Ability to configure DNS servers based on mDNS/DNS-SD published information, a feature that is very usefull on IPv6 which has no other mechanism for this. * Combined with nss-mdns, allows hostname lookup such as 'laptop.local' without the configuration of a DNS server. http://0pointer.de/lennart/projects/nss-mdns/ * Easy integration into GLIB, GTK other mainloop applications. * Documentation and examples of both developer APIs and utilities. mDNS/DNS-SD is part of a larger set of specifications for easy configuration of networking known as "ZeroConf" (http://www.zeroconf.org/), with the aim of allowing you to plug into a network and instantly be able to interact with it's services. Avahi was designed to be a fully free implementation, and is available under the LGPL. Many other implementations of the mDNS/DNS-SD specification were previously non-free, restricting their use in many platforms such as the GNOME desktop and many distributions. While Avahi is a 0.1 release, we feel it is feature complete and available for immediate use, developers can make use of the Avahi client library to provide above mentioned functionality in their programs. We unfortunately do not have a logo yet! We would love if someone could suggest ideas for a logo or even design us one.
