======================================================= Release notes for Sofia-SIP version 1.12.6 (2007-04-25) ======================================================= Sofia-SIP is an open-source SIP User-Agent library, compliant with the IETF RFC3261 specification. It can be used as a building block for SIP client software for uses such as VoIP, IM, and many other real-time and person-to-person communication services. The primary target platform for Sofia-SIP is GNU/Linux. Sofia-SIP is based on a SIP stack developed at the Nokia Research Center. Sofia-SIP is licensed under the LGPL. Changes since last release -------------------------- Numerous nua bugs introduced in the release 1.12.5 have been fixed. Support for nextnonce in Authentication-Info header has been added. The nua engine now fully supports application-driven SDP. API/ABI changes and versioning ------------------------------ libsofia-sip-ua: - Use calling/received callstate in nua_i_state event sent because of UPDATE while call is ready - Added tag define NUTAG_WITH_CURRENT() as an alias to NUTAG_WITH_THIS() - Added tag NUTAG_DIALOG() controlling whether nua_method() creates a dialog. - Added tag NUTAG_AUTH_CACHE() determining when to include credentials in the request - Added kqueue and /dev/poll interfaces (su_devpoll_port_create(), su_devpoll_clone_start(), su_kqueue_port_create(), su_kqueue_clone_start() in ) - Added SIP_IS_ALLOWED() macro to - Fixed NUTAG_APPL_METHOD() implementation for UPDATE and PRACK as documented ("100rel" and "precondition" extensions now require explicit calls to nua_update() and nua_prack() if those methods are included in NUTAG_APPL_METHOD()) - Added auc_clear field and member to authentication client plugin interface in - Added nua_event_is_incoming_request() to - This release is ABI/API compatible with applications linked against any 1.12.x release. However, applications built against this release won't work against an older library. The ABI has been tested with the nua module unit test (test_nua) built against original 1.12.0 release. libsofia-sip-ua-glib: - No ABI/API changes, compatible with 1.12.0. Note, libsofia-sip-ua-glib interface is not considered stable and may change in a future 1.12.x release. Contributors to this release ---------------------------- - Pekka Pessi (/dev/poll interface to Solaris, kqueue) - Martti Mela (kqueue interface to Max OS X and FreeBSD) - Michael Jerris (Solaris patches) - Colin Whittaker (sresolv patch) See the AUTHORS file in the distribution package. Notes on new features --------------------- The Sofia-SIP has been compiled and tested on Solaris. The /dev/poll interface (in su_devpoll_port.c) has been added for Solaris. Likewise, the kqueue interface (in su_kqueue_port.c) has been added for FreeBSD and Mac OS X. There is also a select-based reactor for systems without poll(). The client authentication in nua has been updated. The nextnonce in Authentication-Info or Proxy-Authentication-Info headers is now used with the next authorized operation. The NUTAG_AUTH_CACHE() policy determines how the cached credentials are used. By default, the credentials are included in each request within the dialog, however, with the NUTAG_AUTH_CACHE(nua_auth_cache_challenged) the client authenticates requests only after they have been challenged. The application can now fully control the SDP negotiation (when soa is disabled with NUTAG_MEDIA_ENABLE(0)). The application can send UPDATE and PRACK requests and respond to them. The callstate sent in nua_i_state after UPDATE while the call has already been completed has been also changed. Bugs fixed in this release -------------------------- - Fixed nua failing to refresh publication with re-PUBLISH. Problem reported by Jan van den Bosch. - Fixed encoding of c= lines without IN address. Problem reported by Saurav Sahu. - Fixed status code sent to network and returned to the client if there was an internal error while responding to a request. The problem was reported by Michael Jerris and Joshua Engelbrecht. - Fixed #1685249, unclear termination of call in absence of credentials by nua_authenticate(). Problem reported by Mikhail Zabaluev. - Fixed status code reported to application when REGISTER transaction was restarted by nua stack. Problem reported by Mikhail Zabaluev. - An invalid Contact was used if STUN was disabled but there was no STUN server. Problem reported by Miguel Freitas. - Fixed problem logging long lines from with TPORT_LOG. Problem reported by Mike Murdock and Michael Jerris. - Nua now includes the SDP capabilities in the response to the OPTIONS - Fixed assertion failure because BYE destroyed a session twice. Problem reported by Michael Jerris. - Fixed crash caused by a 0-length UDP datagram. Problem reported by Michael Jerris. - Fixed the 305 response handling by nua stack. Bug #1676445 reported by Fabio Margarido. - Fixed authentication-related bugs #1685245 and #1570746. #1685245 reported by Mikhail Zabaluev. - Fixed problems resuming DNS after server or link downtime. Bug #1631198 reported and initial patch submitted by Colin Whittaker. - Fixed NUTAG_APPL_METHOD() implementation for UPDATE and PRACK as documented - Fixed crashes in nua state engines: - when nua_invite() was called second time before receiving final response to first INVITE - when UAS expected PRACK but received CANCEL - when UAC received error response to PRACK, it tried to send BYE and crashed - when UAS rejected initial request, the subsequent request with same dialog id (Call-ID, From-tag) crashed (dialog cleanup code left dialog dangling) Problems reported by Michael Jerris - Fixed crash in nta state engine: - DNS resolver failure in non-invite transactions crashed - Fixed SDP handling when soa is disabled (NUTAG_MEDIA_ENABLE(0)).
