[Serusers] Re: [Serdev] ser 0.8.12 released

We have just released a new ser stable version: ser 0.8.12. This version fixes a lots of bugs, has some performance improvements (it's a little faster :-)) a.s.o (for more information read the attached NEWS file). The code is based on the cvs head from 14 Oct 2003. The following things which are on the current CVS head are not part of this release: - tcp aliases - automatic content-length updating (this means nathelper won't work as well as with the HEAD version, so for nat traversal stick to the unstable version) - latest permissions updates All 0.8.11 users which are using tcp a lot should upgrade, since 0.8.12 contains many tcp fixes which were not backported to 0.8.11-r1. Three new modules were added to the default build process and to the binary distribution: - auth_diameter (diameter based authentication with disc) - mangler (changes Contact and SDP ip addresses/ports, can be used in some nat traversal scenarios) - pdt (translates numerical codes into domains, based on prefixes, and updates the URI) This release was tested on: linux/x86, linux/arm, freebsd 4.5 & 5.1/x86, netbsd 1.6/sparc64, openbsd 3.2/x86, solaris 8/sparc64. The new release can be downloaded from: ftp://ftp.berlios.de/pub/ser/0.8.12 (source code, pre-compiled binaries for various arhitectures, packages for various operating systems and linux distributions; for more informations see ftp://ftp.berlios.de/pub/ser/0.8.11/README). You can also use cvs, just remember to add -r rel_0_8_12 to your cvs checkout command. Andrei

Release notes for SIP Express Router (ser) *********************************************** $Id: NEWS,v 1.17.2.2 2003/11/20 10:57:22 andrei Exp $ *********************************************** * Changes/fixes introduced in 0.8.12 *********************************************** +--------------------------------------------------------+ | WARNING: if you want to use a 0.8.11 config script | | with 0.8.12, replace if ( len_gt(number) ) with: | | if ( msg:len > bumber ) | +--------------------------------------------------------+ New Features ============ texops: - subst('s/re/repl/flags') support core: - added switch to check the config file (-c) - changes: removed len_gt() and replaced with if (msg:len op number|max_len) - multiple operator support: ==, != for special operations (e.g myself, ip) ==, !=, ~= for strings ==, !=, >, <, >=, <= for integers - new config variables: advertised_address= ip | string address advertised in via and in the DST_* lumps (e.g RR) This is the default value, if empty (default) the socket address will be used. WARNING: - don't set it unless you know what you are doing (e.g. nat traversal) - you can set anything here, no check is made (e.g. foo.bar will be accepted even if foo.bar doesn't exist) advertised_port= no port advertised in via and in the DST_*lumps (e.g. RR) This is the default value, if empty (default) the socket port will be used. Same warnings as above. - new script commands: set_advertised_address(ip|string) same as advertised_address but it affects only the current message: Message host/lump address= the set_advertised one if present, else advertised_address else socket address. set_advertised_port(no) same as advertised_port but it affects only the current message; see set_advertised_address & s/address/port/g usrloc: - usernames are case insensitive registrar: - lookup function succeeds when appending of a branch failed auth_db: - support for rpid stored in database (thanks to Jakob Schlyter) Bug fixes ========= - memory leak in digest credentials parser fixed - authenticathion ha1 didn't include domain if username was of the form user@domain and calculate_ha1 was set to yes (modules/auth_db) - tm reply processing race condition (modules/tm), special thanks go to Dong Liu - Many bugs in pa module fixed, works with registrar again. Security updates ================ - fifo processing code will write responses only to other fifos and only if they are not hard-linked, also default ser fifo persmissions were changed to 0600. Performance improvements ======================== - tuned internal malloc implementation parameters to better reflect the actual workload (malloc is a little bit faster now) *********************************************** * Changes introduced in 0.8.11 *********************************************** +--------------------------------------------------------+ | CAUTION: the 0.8.11 release include changes which | | are incompatible with scripts and databases used | | in previous versions. Care is advised when upgrading | | from previous releases to 0.8.11. | +--------------------------------------------------------+ New features ============= - RFC3261 support - TCP support and cross-transport forwarding [core] - loose routing support [rr module] - New modules - vm -- voicemail interface [vm] - ENUM support [enum] - presence agent [pa] - dynamic domain management -- allows to manipulate hosting of multiple domains in run-time [module] - flat-text-file database support [dbtext] - rich access control lists [permissions] - Feature Improvements - click-to-dial, which is based on improved tm/FIFO that better supports external applications [tm module] - web accounting -- acc module can report to serweb on placed calls [acc module] - improved exec module (header fields passed now as environment variables to scripts) [exec module] - Architectural Improvements - powerpc fast locking support - netbsd support - 64 bits arch. support (e.g. netbsd/sparc64). - New Experimental Features (not tested at all yet) - nathelper utility for Cisco/ATA NAT traversal [nathelper] - another NAT traversal utility [mangler] - postgress support [postgress] - fcp module [fcp] - pdt module (prefix2domain) [pdt] Changes to use of ser scripts ============================= About Multiple Transport Support -------------------------------- SER now suports multiple transport protocols: UDP and TCP. As there may be UAs which support only either protocol and cannot speak to each other directly, we recommend to alway record-route SIP requests, to keep the transport-translating SER in path. Also, if a destination transport is not known, stateful forwarding is recommended -- use of stateless forwarding for TCP2UDP would result in loss of reliability. core ---- - reply_route has been renamed to failure_route -- the old name caused too much confusion - forward_tcp and forward_udp can force SER to forward via specific transport protocol acc module: ----------- - radius and sql support integrated in this module; you need to recompile to enable it - acc_flag is now called log_flag to better reflect it relates to the syslog mode (as opposed to sql/radius); for the same reasons, the accounting action is now called "acc_log_request" and the option for missed calls "log_missed_calls" - log_fmt allows now to specify what will be printed to syslog auth module: ------------ - auth module has been split in auth, auth_db, auth_radius, group group_radius, uri and uri_radius - all the parameters that were part of former auth module are now part of auth_db module - auth_db module contains all functions needed for database authentication - auth_radius contains functions needed for radius authentication - group module contains group membership checking functions - group_radius contains radius group membeship checking functions - is_in_group has been renamed to is_user_in and places to groups module - check_to and check_from have been moved to the uri module im module: ---------- - im is no longer used and has been obsoleted by TM exec module: ------------ - exec_uri and exec_user have been obsoleted by exec_dset; exec_dset is identical to exec_uri in capabilities; it additionaly passes content of request elements (header fields and URI parts) in environment variables; users of exec_user can use exec_dset now and use the "URI_USER" variable to learn user part of URI - exec_dset and exec_msg return false, if return value of script does not euqal zero - exec_dset takes an additional parameter, which enables validation of SIP URIs returned by external application jabber module: -------------- - presence support for Jabber users is enabled loading the PA module and using handle_subscribe("jabber") for SUBSCRIBE requests to jabber user msilo module: ------------- - m_store has now a parameter to set what should be considered for storing as destination uri. This enables support for saving the messages on negative replies. radius_acc module: ------------------ - radius_acc module has been removed and radius accounting is now part of acc module registrar/usrloc modules: ------------------------- - multi domain support, the modules user username@domain as AOR if enabled - descent modification time ordering of contacts - case sensitive/insensitive comparison of URI can be enabled rr module: ---------- - addRecordRoute has been replaced with record_route - rewriteFromRoute has been replaced with loose_route() - a new option, "enable_full_lr" can be set to make life with misimplemented UAs easier and put LR in from "lr=on" - rr module can insert two Record-Route header fields when necesarry (disconnected networks, UDP->TCP and so on) tm module: ---------- - t_reply_unsafe, used in former versions within reply_routes, is deprecated; now t_reply is used from any places in script - t_on_negative is renamed to t_on_failure -- the old name just caused too much confusion - FIFO t_uac used by some applications (like serweb) has been replaced with t_uac_dlg (which allows easier use by dialog- oriented applications, like click-to-dial) - if you wish to do forward to another destination from failure_route (reply_route formerly), you need to call t_relay or t_relay_to explicitely now - t_relay_to has been replaced with t_relay_to_udp and t_relay_to_tcp
