[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Added SOFIAPUBFUN to few functions in msg_parser(). Added new C++ wrappers for C files that need C++ linkage in tport_test. Fixed setlocal braino in build_sources.cmd. * Compiling and linking torture_su_bm and torture_su_port as static on win32. * Added more warnings to ignore on VC to win32/config.h.in. * Added files missing from dist to win32/Makefile.am * Added msg_get_address() and msg_set_address() functions to Trying to solve ai_addrlen problem. * Put last fixes into RELEASE file. * Fixed binding problems in nua and nta.c. Returning more appropriate error code from tport_tbind(), too. This patch fixes tracked bugs #1485624 (nua not binding to 5060), #1485625 (nua_create() fails if STUN init fails) and #1485632 (ncorrect error message for nua bind error). Nua now also binds both to NUTAG_URL and NUTAG_SIPS_URL() URIs, nua_create() fails if binding either of them fails. * Fixed msg_addrlen() usage. msg_addrlen() returns a pointer to ai_addrlen field of struct addrinfo inside the msg_t object. ai_addrlen has type size_t. However, system calls taking a return valur pointer to address length, use type socklen_t. Typically size_t is unsigned long, socklen_t is int, so casting msg_addrlen() return value to (socklen_t *) will break on (high-endian) 64-bit platforms. svsp. * Re-enable natify in test_nua.c. * Updated nua_register() and NUTAG_OUTBOUND() documentation. Taking NUTAG_OUTBOUND() options correctly into account in outbound.c. Improved the contact validation process in outbound.c, too. * Silenced warnings caused by mismatching integral types. In nua_session, unsigned v. sip_time_t. In tport.c, size_t v. socklen_t. * Fixed socket semantics on test_nat.c for BSD, too. * Fixed type of msg_addrlen() to size_t in msg_addr.h/msg.c. POSIX socklen_t is not used in addrinfo. We use addrinfo. * Added Changes to RELEASE. * Fixed DIST_SUBDIRS at toplevel Makefile.am. * Fixed AM_LDFLAGS in sresolv/Makefile.am. * Not declaring inline functions with global scope in * Added su_source_create() prototype to su-glib/so_source.c. 2006-05-11 Pekka Pessi * Added more info about outbound, gruu and win32 DLL to RELEASE. * sres.c: storing last dot into the error record, too. Bug reported by Thomas Rosenblatt. * Added new files to dist, too. - libsofia-sip-ua/sresolv/sofia-resolv/sres_config.h - win32/libsofia-sip-ua-static/libsofia_sip_ua_static.dsp - win32/tests/test_nua/test_nat_tags.cpp * Now building libsofia_sip_ua.dll on win32. We define both IN_LIBSOFIA_SIP_UA and IN_LIBSOFIA_SRES in libsofia_sip_ua.dsp. Because of DLL linkage, we compile tags typedefs as C++ (see win32/tests/test_nua/test_nat_tags.cpp). Removed LIBSOFIA_SIP_UA_STATIC from win32/sofia-sip/su_configure.h. Added libsofia_sip_ua_static.lib, too. If you want to compile against that, you need define LIBSOFIA_SIP_UA_STATIC by yourself. Added libsofia-sip-ua-static/libsofia_sip_ua_static.dsp. Using multithreaded DLL runtime for all projects. * Added SOFIAPUBFUN/SOFIAPUBVAR to stun module, too. * Added test_nat_tags.c to nua module. * Fixed a memory leak in nta_outgoing_mcreate(). * Added SRESPUBFUN and sres_config.h to sresolv module. * Updated headers.

Removed some deprecated functions and macros. * Avoid #include ordering problem with sip_parser.h in sip_test_msg.c, too. * Silenced warnings in tport_type_tcp.c. * Added @deprecated to deprecated sip functions. * Moved ntlm functions to auth_ntlm.h from auth_plugin.h> in iptsec module. * Reordered #includes in http module. Avoid #include ordering problem with . * Removed utf8 and unicode-related stuff from library. Source files are still included in source tar. * Reordered #includes in sip module. Avoid #include ordering problem with sip_parser.h. * Updated ADD-A-HEADER file in sip module. * Added SOFIAPUBFUN and SOFIAPUBVAR to all public nua functions and variables. 2006-05-10 Pekka Pessi * nua/outbound.c: Adding Accept-Contact (a) to keepalive OPTIONS, too. Just in case the message gets forwarded. * Remove dependency to Makefile in targets for marshal file generation in nua_glib. * Fixed includes in outbound.[hc]. * Added Doxyfiles to libsofia-sip-ua-glib. Note that the files are not actually commented. * nua, soa: Adding Warnings to the response if appropriate. * Refactored outbound code in nua module.

Allow SIPS uris in contacts, too. * nua_register.c: ignoring bad received parameters in Via header. * Updated config file handling in sresolv/sres.c. Using reference counting with config structure when copying resolver objects. Trying harder to avoid re-parsing resolv.conf and checking for updated servers. Changed SRES_UPDATE_INTERVAL_SECS to 5 for non-WIN32 platforms. * su/su_alloc.c, su/sofia-sip/su_alloc.h: su_home_ref() takes const pointer. 2006-05-08 kai.vehmanen@nokia.com * Added sip_dig and stunc to VC6/win32 workspace file. * Fixed sip_dig errors when building on VC6/win32. * Fixed STUN bugs when build with VC6/win32. * Updated STUN NAT type check interface to utilize current IETF BEHAVE terms. * Print sofia-sip version in stunc usage. 2006-05-08 Pekka Pessi * url module: using SOFIAPUBFUN and SOFIAPUBVAR instead of URL_DLL. * Fixed overflow problem with su_timer_run(). After 25 days the su_timer_run() timer started to misbehave, 1 < <31 milliseconds is bit more than 24 days, 20 hours, 31 minutes... 2006-05-06 kai.vehmanen@nokia.com * Pretty-print the NAT type check results with STUN stunc. * Do not use resend when doing NAT type checking with STUN. The resends do not currently include the request attribute bytes as they should do. * Minor mods to STUN module. * Added optional local port randomization to stunc. Making repeated checks from the same local port will produce unreliable results. * Fixed STUN's Test-IV. * Added lots more documentation about the STUN nattype algorithm. Added a Test-IV step that is improved over the RFC3489 algorithm. * Refactored the STUN nattype checks.

It is now possible to given STUN server address as a hostname instead of requiring a dotted decimal IP-address. * Always install auth_ntlm.h as it is needed by auth_client.h. 2006-05-04 kai.vehmanen@nokia.com * Updated developer docs w.r.t. VCS system. Darcs is now the primary version control system and sf.net CVS is only used as a backup. * Fixed header paths and added missing libraries that caused errors with debug/release builds. * Added sip_options to the win32 SofiaSIP workspace. 2006-05-04 Pekka Pessi * sres_cache.c: fixed problem using macro as offsetof() argument. * test_sresolv.v: added more tests for A6 record parsing. * sres.c, sres_cache.c: records are now allocated in a single chunk. Bug hunted down by Thomas Rosenblatt: strings and domains belonging to record were allocated from resolver home, not from cache home. * Fixed problem with config without search domains in sresolv/sres.c. * Added information for COPYRIGHTS file to README.developers. * Setting send buffer size to at least 64K in Windows in tport_type_tcp.c. * Using SOFIAPUBFUN and SOFIAPUBVAR in bnf.h. * Silenced sprious warnings by MSG_HEADER_INIT() in msg_header.h. * NUTAG_KEEPALIVE() now uses milliseconds.

Using nat by default. Added --symmetric and -N options, enabling symmetric nat and logging, respectively. * Added tags to nua/test_nat.[hc]. TESTNATTAG_SYMMETRIC(1) enables symmetric nat. TESTNATTAG_LOGGING(1) enables logging of nat binding changes. * Updated outbound protocol engine in nua/nua_register.c We enable rport and disable outbound by default. Fixed problem when nat binding was changed. Fixed syntax error problems when creating Accept-Contact header in OPTIONS request used to validate registration. * Added nua_generate_instance_identifier() to nua module. * Changed default values in nua_params.c.

Registrar was not returning all contacts in 200 OK to response to REGISTER. * iptsec module: * Added auc_copy_credentials(). Implementation in iptsec/auth_client.c, prototype in . Replaced msg_param_t with char const *, too. * Added SOFIAPUBFUN to auth_struct_copy(), too. * iptsec module (by Martti Mela): * ntlm support now compiles, not working. * added auth_ntlm.[ch] * more NTLM methods and header file auth_ntlm.h * still more ifdefs for NTLM enabling * added configure flag for enabling NTLM (disabled by default) * fixed gssapidatas * NTLM implementation continued. 2006-05-02 Pekka Pessi * iptsec module: * Updated headers in iptsec module. Added SOFIAPUBFUN and SOFIAPUBVAR where needed. Removed auc_with_uicc(). * Fixed memory management problems in iptsec module. The authenticator client in auth_client.c leaked memory when re-challenged. The client did not duplicate strings from challenge, and tried to use freed values after challenge was freed. Now we are actually running the tests in test_auth_digest.c, too. The problem was reported and patch submitted by Colin Whittaker. * sresolv module: * Updated sresolv API. Added sres_search() and sres_search_cached_answers() to the sresolv API. Added sres_blocking_search().

Problem reported by Colin Whittaker. * Updated documentation of auc_authorize() in iptsec/auth_client.c. * Added null pointer check to auc_authorize() in iptsec/auth_client.c. Patch proposed by Colin Whittaker. * Destroying session when initial INVITE is CANCELed. Patch proposed by Colin Whittaker. 2006-04-27 Pekka Pessi * sresolv module: Added SRESTAG_CACHE() to . Added ends0 and no-edns0 options in resolv.conf to sresolv/sres.c. Fixed sresolv #includes. Added #include and into sresolv/sres.c Added prerequisite #includes to sresolv files. Added @todo about cache poisoning. Updated sresolv documentation. Fixed bugs in sresolv/sres_blocking.c. Silenced printing spurious network errors in sresolv/sres.c. Added sres_is_blocking() to sres_blocking.c. Updated sres_resolver_get_async(), too. Added sip-dig.c to sresolv module. * tport module: Added missing "typedef" keyword to tport_pri_type_t in sofia-sip/tport_tag.h Fixed TPTAG_CONNECT() usage in tport/tport.c. Now running some SCTP tests in test_tport.c Updated tport_tls.c: - Not requiring client certificate in tls. - Tried to improve error handling, too. Now using stream-like sending semantics with SCTP. Updated datagram reception in tport_type_udp.c. We now avoid peeking and fussing around with message size, and simply allocate 64K buffer, receive(), then reduce the buffer size. Updated tport_recv_stun_dgram() in tport_stub_stun.c. Now using already received data within a msg_t. Updated SigComp interface in tport_stub_sigcomp.c and tport_sigcomp.c. Added a slot for stun handle to all primary transports. Changed tport_primary_t in tport_internal.h, updated tport_type_stun.c. Moved rest of the threadpool stuff into tport_threadpool.c. tport_threadpool.c does not work at the moment, disable it. Updated tport_connect() interface. Calling tport_alloc_seconary() when client socket has been created, making it possible to set socket options before connecting the socket. Currently, this benefits SCTP and TLS. This change affects tport_internal.h, tport.c, tport_type_sctp.c, tport_type_tcp.c, and tport_type_tls.c. Added TPORT_DLL to tport_keepalive(), too. Added tport_ref() and tport_unref() to tport module. Fixed bug #1473936 in tport/tport.c. tport_primary_by_name() now returns transports regardless of their protocol family if tpn->tpn_host is not a literal IP address. * msg module: Updated msg_recv_buffer() prototype. Reclaiming the un-committed part of buffer in msg/msg_parser.c. The allocation pattern for UDP has changed: now we allocate 64K, then realloc to the actual size. * nta module: Fixed bug #1472683 in nta/nta.c. The rport parameter was missing from ACK. The CANCEL had Via line with duplicate branch parameter. Fixed merge artifact in nta/test_nta_api.c. Always having NTATAG_SIGCOMP_OPTIONS() and storing its value. * nua module: Added explicit check for NULL pointers to unregister_expires_contacts(). Added missing events to nua.docs. More fixes to nua/nua_publish.c. nua_unpublish uses tags from initial nua_publish() 900 status is returned when there is no Expires header in 2XX response to PUBLISH. Re-indented nua_publish.c. Added better error checking to nua_creq_msg(). Fixed Service-Route header processing, too. Added nua_add_contact_by_aor() to nua_register.c. The nua_add_contact_by_aor() takes care of adding other registration-related headers like Service-Route, too. Moved nua_publish() documentation from nua.c/nua.docs to nua_publish.c. Updated documentation, added nua_r_unpublish documentation. Improved PUBLISH handling in nua/nua_publish.c. Saving the initial PUBLISH message along with message body and content type. They are re-used if 412 is received or if 2XX response contains Expires: 0. If 2XX response is received without Expires header, we report internal error to application. Fixed route handling in SUBSCRIBE in the file nua/nua_subnotref.c. There was a problem using dialog route set when there was an initial route original SUBSCRIBE. * Updated copyright year in sofia-footer.html.in. * Fixed prototype of host_is_domain(). * Fixed doxygen warnings in su module. * Updated sofia-sip.spec.in. Separated glib library to sofia-sip-glib and sofia-sip-glib-devel packages.

When PRACK is sent using nta_outgoing_tmcreate(), there is functions nta_outgoing_setrseq() and nta_outgoing_rseq() for updating the rseq number within transaction. * Corrected su_torture.c, Shutdown semantics differ on WINSOCK/BSDSOCK. * Fixed su_wait() with 0 wait objects in windows. * Fixed win32-compatibility problems in test programs. * Not using NULL restart pointer in ua_authenticate(). 2006-02-14 Pekka Pessi * Fixed problems with sofia-sip/ header prefix in win32. * Fixed win32/VC configuration problems. * Fixed win32 pthread dist. * Fixed include paths. * Use #include . * Be explicit with input when generating source files. * Added make target clean-built-sources. * Fixed #include su_module_debug.h. * Moved public include files to sofia-sip subdirectories. All public include files installed in ${sofiadir} are now in sofia-sip subdirectories. They are installed to ${sofiadir}/sofia-sip, too. ${sofiadir} is defined by configure script relative to your ${prefix}, by default ${sofidir} is ${prefix}/include/sofia-sip-1.11. The default prefix is /usr/local and ${sofiadir} is /usr/local/include/sofia-sip-1.11. When using package manager, the ${prefix} is usually /usr and ${sofiadir} is /usr/include/sofia-sip-1.11. The public include files should be referenced using sofia-sip path, e.g., . You can either fix your applications to use the new include file names with the fix-include-sofia-sip sed script found in scripts/ directory, or add both ${sofiadir} and ${sofiadir}/sofia-sip into your include path, e.g., INCLUDES = -I/usr/include/sofia-1.11 -I/usr/include/sofia-1.11/sofia-sip At the same time, I took the liberty to rename two include files sofia_sip_features.h => sofia-sip/features.h su_memmem.h => sofia-sip/su_bm.h The fix-include-sofia-sip sed script takes care of both of them. * Improved 100rel handling in nua. Added test_100rel to test_nua.c. * Using CONDITION_PARAMS macro instead of CONDITION_FUNCTION in test_nua.c * Improving getaddrinfo replacements. Testing functions getaddrinfo()/freeaddrinfo(), getnameinfo() and gai_strerror() separately. There is no gai_strerror() in windows, I think. 2006-02-03 Pekka Pessi * Code cleanup and memory leak fix in soa/sdp. Fixed memory leak related to parsing sdp in soa.

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. Quick start ----------- Sofia-SIP uses the GNU autotools, so building procedure is the usual: sh> sh autogen.sh (if building from darcs) sh> ./configure sh> make sh> make install See also 'docs/devel_platform_notes.txt' for notes on compiling Sofia-SIP in different environments. See the "options-client-example" (available using darcs at http://sofia-sip.org/repos/options-client-example/ or with CVS as a module in Sofia-SIP CVS tree) for an example of a small app that is utilizing Sofia-SIP, and specifically the libsofia-sip-ua library component. There are also multiple example clients under the "sofia-sip/utils" directory: - sip-options, query using SIP OPTIONS method - sip-date, SIP date printer/parser The Sofia-SIP su submodule also provides some small utilities: - addrinfo (libsofia-sip-ua/su), resolve host names - localinfo (libsofia-sip-ua/su), prints information about local network interfaces References ---------- Project website: - http://sofia-sip.sourceforge.net - http://www.sourceforge.net/projects/sofia-sip Mailing list: - http://sourceforge.net/mail/?group_id=143636 Version control repositories: - see the project website (link above) Licensing --------- Sofia-SIP is licensed under terms of the GNU LGPL. See the file "COPYING" for more information. sofia-sip-1.12.11+20110422.1/README.developers000066400000000000000000000101151223300710500176130ustar00rootroot00000000000000=============================================================== README.developers - Sofia-SIP development practices =============================================================== Introduction ============ This file is a collection of practices and rules for Sofia-SIP development. If you have questions, or would like to make changes, raise the issue on sofia-sip-devel (see http://lists.sourceforge.net/lists/listinfo/sofia-sip-devel ). Important files for developers ============================== AUTHORS List of contributors. When contributing new code, add yourself to AUTHORS, and also remember to update the per source file copyright statements. COPYRIGHTS List of licenses and related copyright statements. While majority of Sofia-SIP is licensed under LGPL, there are a few files with different, but LGPL compatible, licensing terms. README.developers This file. TODO Not in active use yet. /ChangeLog files All non-trivial changes to the source code should be documented in the ChangeLog files. See also the top-level ChangeLog. Version numbering ================= Package version --------------- For public releases, the package version is: vMAJOR.MINOR.REVISION, where MINOR is even For development releases and snaphots the version is one of: vMAJOR.MINOR.REVISION, where minor is odd vMAJOR.MINOR.REVISION.YEAR.MONTH.DAY, where minor is odd For all releases, the version should be changed in configure.ac and committed to Darcs/CVS before making the release package. The person doing the release is responsible for updating the version number. Library interface versions -------------------------- Sofia-SIP libraries utilize libtool interface versioning. See - http://www.gnu.org/software/libtool/manual.html#Versioning - http://www.gnu.org/software/libtool/manual.html#Using-Automake The interface versions are set in top-level 'configure.ac' file. Additionally, the SONAME version (CURRENT-AGE) is set in the same place. These version numbers are available for use as autoconf variables (see the library 'Makefile.am' files and 'packages/sofia-sip.spec.in'). All changes to the library versions should be marked to the appropriate library 'ChangeLog' file. The library version should be changed at the same time as the first interface change is committed since the previous release. The interface version is frozen (should be marked to the 'ChangeLog' file) at the time the next release is tagged (in other words, intra-release changes need not be tracked with libtool versions). The goal should always be to avoid breaking the API/ABIs until absolutely necessary. Interfaces clearly marked as private can be changed without change to library interface version, but otherwise all public functions, types, variables and definitions fall under interface change control. Version control tags ==================== Tagging releases and snapshots ------------------------------ - source repository (*) - master Darcs tree at: http://sofia-sip.org/repos/sofia-sip - CVS tree (only used to track major releases) at: http://sourceforge.net/cvs/?group_id=143636 - tags: rel-sofia-sip-x_y_z - stable and development releases (matches release version sofia-sip-x.y.z) - tags: snapshot_rel_YEARMMDD - snapshot releases at http://sofia-sip.sourceforge.net/snapshots/ Notes (*): - Information about Darcs: http://abridgegame.org/darcs/ http://lwn.net/Articles/110516/ Sending patches =============== People without Darcs access --------------------------- Send your patches to sofia-sip-devel. Someone from the development team (see AUTHORS) will handle the patch. People with Darcs access ------------------------ Trivial changes can be committed without review. For non-trivial changes, you should first send a proposal to sofia-sip-devel and wait for comments. There are no strict approval rules so use of common sense is recommended. ;) Tips for making patches ----------------------- - test your patch on a clean checkout from version control system - remember to check for updates before pushing your changes to the master repository sofia-sip-1.12.11+20110422.1/RELEASE000066400000000000000000000072651223300710500156030ustar00rootroot00000000000000============================================== Release notes for current version of Sofia-SIP ============================================== Changes since last release -------------------------- Bugs in blaa and foo have been fixed. The stack now supports use of foobar... API/ABI changes and versioning ------------------------------ **template**: New features in API are marked with Doxytag macro @VERSION_1_XX_X. libsofia-sip-ua: - **template**: Added foobar() function (sofia-sip/foobar.h). - Added SOATAG_USER_O_LINE() tag (sofia-sip/soa_tag.h) - Added msg_q_value() function (sofia-sip/msg_mime.h). - Added msg_accept_match() function (sofia-sip/msg_mime.h). - Added NUTAG_AUTO100() tag (sofia-sip/nua_tag.h) - Added NUTAG_ACCEPT_MULTIPART() tag (sofia-sip/nua_tag.h). - Added NUTAG_MAX_RETRY_AFTER() tag (sofia-sip/nua_tag.h) - Added NUTAG_APPL_EVENT() tag (sofia-sip/nua_tag.h) - Added NUTAG_DEFERRABLE_TIMERS() tag (sofia-sip/nua_tag.h). - Added typedef su_time64_t and functions su_now64(), su_stamp64(), su_time64_to_time(), su_time_to_time64(), su_time64_add(), and su_duration64() (sofia-sip/su_time.h). - Added su_root_stamp64() and su_root_stamp64_offset() (sofia-sip/su_wait.h). - 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 ---------------------------- - - **template**: First Surname (patch to nua/soa/msg) See the AUTHORS file in the distribution package.

This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

The instructions are aimed at developers. Quick start =========== To build Sofia-SIP:: sh> ``./autogen.sh`` (if building from a fresh Git checkout) sh> ``./configure`` sh> ``make`` Note that autogen.sh expects to have automake 1.9. If using a newer automake, generate the GNU autotool files using the command autoreconf. Autotool notes ============== Macros ------ Sofia-SIP specific macros are prefixed with "``SAC\_``" and are defined in files under the toplevel "m4/" directory. Makefile target notes --------------------- - all optionally compiled source files should be listed separately in ``DIST_SOURCES`` variable (otherwise ``make dist`` will fail) Makefile fragments ------------------ Some common makefile rules are in 'rules' subdirectory. Maintainer mode --------------- Sofia-SIP tree is by default configured with automake maintainer mode disabled. In other words, Makefiles do not contain rules for recreating or updating configure, Makefiles or other autotool-generated files. To update these files, you need to run top-level autogen.sh script. Those developers who need to often modify configure.ac, Makefile.am and macro files, can enable maintainer mode with configure option '--enable-maintainer-mode'. Running tests ============= Sofia-SIP has quite complete suite of test cases. It is prudent to run them while making changes and before committing them to revision control system. However, running certain tests takes quite a long time to execture. Therefore, they are run only if the environment variable EXPENSIVE_CHECKS has been set. EXPENSIVE_CHECKS is also set by the build system if configure option '--enable-expensive-checks' has been used. On selectes architectures, it is possible to run tests under valgrind. Use the make target 'valcheck' for that purpose. Code-tree layout ================ Most of the code resides in the libsofia-sip-ua directory. The main library, libsofia-sip-ua.so, is created by collecting object files (for example bnf/bnf_objs.o) from individual modules. There are some portability issues with the way the shared library is currently built, and we are looking for ways to improve the situation. Making releases =============== See sofia-sip/docs/release_management.txt Developer documentation ======================= Generating reference documentation from source code --------------------------------------------------- The libsofia-sip-ua library has a top-level make target "doxygen" for generating the HTML reference documentation. The pages will be created to libsofia-sip-ua/docs subdirectory. This special target is primarily meant for use by the Sofia-SIP website admins, but can be used by anyone with the proper set of tools: - Doxygen, http://www.stack.nl/~dimitri/doxygen/ - Dot graph tool, http://www.research.att.com/sw/tools/graphviz/ sofia-sip-1.12.11+20110422.1/docs/devel_platform_notes.txt000066400000000000000000000027171223300710500225010ustar00rootroot00000000000000====================================================== Notes on compiling Sofia-SIP in different environments ====================================================== Using GNU Autotools ------------------- If you modify autoconf or automake files (configure.ac or Makefile.am) or if you compile Sofia SIP that you pulled from darcs or CVS repo, you need up-to-date autotools. Autoconf should be at least 2.57 and automake should be at least 1.7. You can avoid running autoreconf explicitly if you use ./configure option --enable-maintainer-mode. Notes to distributors ---------------------- Build options such as "--disable-stun" (HAVE_SOFIA_STUN) and "--disable-nth" (HAVE_SOFIA_NTH) modify the public library API/ABI, by omitting certain interfaces from the resulting library and installed header files. Options such as '--disable-size-compat' modify the library ABI by changing the types used in public library function signatures. Generic POSIX (GNU/Linux, BSD, ...) ----------------------------------- Sofia-SIP should compile out-of-the-box on generic POSIX machines. Use the standard GNU autotool 'configure+make' procedure to build the software. See top-level README file for more information. The configure script accepts various options. See "./configure --help" for the full list.

Links to other resources ======================== sofia-sip/README.developers The release notes ================= The release notes should contain the following sections: - about Sofia-SIP - copied verbatim from sofia-sip/README - list of changes since last release - maintained in sofia-sip/RELEASE - see diff between cvs/darcs between previous and this version - written in freshmeat.net "Changes:" style - notes on API/ABI interface changes - maintained in sofia-sip/RELEASE - all changes in public interfaces, plus other notes that developers should be aware of - contributors to this release - maintained in sofia-sip/RELEASE - also sofia-sip/AUTHORS should be updated (file should list all persons/companies who have code/scripts/etc copyrighted to them in the sofia-sip tree) See the RELEASE.template file for a full list of release note sections. Making the release tarball ========================== - basics: check system clock of the build host ;) - update the version number in sofia-sip/configure.ac - make sure the library versions are correct, and you've frozen all library interfaces (with correct entries in ChangeLog files), see README.developers for more information on library versioning in general - make sure everything that is supposed to be in the release is in the master darcs tree - run 'make distcheck' to verify everything is ready for release (requires automake-1.7 or newer) - tag repos (git and any slave trees) with release tag 'rel-sofia-sip-x_y_z', where x_y_z is the version number (see README.developers): sh> git tag "rel-sofia-sip-x_y_z" - take a fresh checkout of the release using the tag in separate clone: sh> git clone . ../release_x_y_z sh> cd ../release_x_y_z sh> git co rel-sofia-sip-x_y_z - create the release tarball with "make distcheck" (make sure depcomp et al libtool scripts are correctly created) - calculate md5 and sha1 hashes using md5sum and sha1sum utilities, and copy the values to the release-notes (see below) Creating the release notes and updating the website =================================================== - combine the sofia-sip/RELEASE contents with the template found from sfnet_www/templates/relnotes.txt - store the resulting release notes to sfnet_www/relnotes/relnotes-sofia-sip-x.y.z.txt - add explicit link to the release notes to sfnet_www/download.html (three most recent releases, see guidelines in the html comments) - update sfnet_www/index.html to mention the latest release - commit the change to sf.net website CVS, and run the sfnet_www/put_online.sh script Uploading the release to sourceforge.net ======================================== - use the the 'Admin' -> 'File releases' tool for creating a new release - to upload the file, you can use for example rsync: rsync -avP -e ssh sofia-sip-x.y.z.tar.gz USER@frs.sourceforge.net:uploads/ - attach the release notes (relnotes-sofia-sip-x.y.z.txt) to the file release Announcing releases =================== - send an announcement mail, containing the release notes, to sofia-sip-devel@lists.sourceforge.net - post a news item to freshmeat.net 'sofia-sip' project (current project owner: Kai Vehmanen) After release ============= - replace the RELEASE file with RELEASE.template, and commit it to master source repository (see sofia-sip/README.developers) - change version in configure.ac from "X.Y.Z" to "X.Y.Zdevel" (as it is in many cases unknown what the next version will be) - make a "tree open for development" commit Checking API/ABI compatibility ============================== - Use a unit test binary built against an old library, to verify a new library version (forwards-compatibility). - Use the 'icheck' tool (in Debian) to make comparison between two released versions. sofia-sip-1.12.11+20110422.1/install-sh000077500000000000000000000332551223300710500166020ustar00rootroot00000000000000#!/bin/sh # install - install a program, script, or datafile scriptversion=2011-11-20.07; # UTC # This originates from X11R5 (mit/util/scripts/install.sh), which was # later released in X11R6 (xc/config/util/install.sh) with the # following copyright and license. # # Copyright (C) 1994 X Consortium # # Permission is hereby granted, free of charge, to any person obtaining a copy # of this software and associated documentation files (the "Software"), to # deal in the Software without restriction, including without limitation the # rights to use, copy, modify, merge, publish, distribute, sublicense, and/or # sell copies of the Software, and to permit persons to whom the Software is # furnished to do so, subject to the following conditions: # # The above copyright notice and this permission notice shall be included in # all copies or substantial portions of the Software. # # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR # IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, # FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Feature Supported Notes
@RFC3261: Basic SIP Protocol The SIP registration and dialog level implementation enables the application to operate as a SIP UA, SIP proxy or a redirect server according to the @RFC3261. The @RFC3261 functionality is divided into five layers: -# message syntax and encoding -# transport -# transaction -# transaction user (UAS and UAC cores, proxy core) -# SIP elements: user agent client and server, proxies, registrars  
@RFC3261 Sections 19 and 20:
Syntax and encoding 		The supported @RFC3261 methods are: @b REGISTER, @b OPTIONS, @b INVITE, @b ACK, @b CANCEL, @b BYE, as well as extension methods INFO, PRACK, SUBSCRIBE, NOTIFY, UPDATE, MESSAGE, REFER, and PUBLISH. Sofia-SIP supports the following SIP headers as specified in @RFC3261 or its extensions (generating, parsing and syntax checking): @ref sip_accept "Accept", @ref sip_accept_encoding "Accept-Encoding", @ref sip_accept_language "Accept-Language", @ref sip_alert_info "Alert-Info" (extension in @VERSION_1_12_7), @ref sip_allow "Allow", @ref sip_authentication_info "Authentication-Info", @ref sip_authorization "Authorization", @ref sip_call_id "Call-ID" ("i"), @ref sip_call_info "Call-Info", @ref sip_contact "Contact" ("m"), @ref sip_content_disposition "Content-Disposition", @ref sip_content_encoding "Content-Encoding" ("e"), @ref sip_content_language "Content-Language", @ref sip_content_length "Content-Length" ("l"), @ref sip_content_type "Content-Type" ("c"), @ref sip_cseq "CSeq", @ref sip_date "Date", @ref sip_error_info "Error-Info", @ref sip_expires "Expires", @ref sip_from "From" ("f"), @ref sip_in_reply_to "In-Reply-To", @ref sip_max_forwards "Max-Forwards", @ref sip_min_expires "Min-Expires", @ref sip_mime_version "MIME-Version", @ref sip_organization "Organization", @ref sip_p_asserted_identity "P-Asserted-Identity" (extension in @VERSION_1_12_7), @ref sip_p_preferred_identity "P-Preferred-Identity" (extension in @VERSION_1_12_7), @ref sip_priority "Priority", @ref sip_proxy_authenticate "Proxy-Authenticate", @ref sip_proxy_authorization "Proxy-Authorization", @ref sip_proxy_require "Proxy-Require", @ref sip_record_route "Record-Route", @ref sip_refer_sub "Refer-Sub" (@VERSION_1_12_5), @ref sip_remote_party_id "Remote-Party-ID" (extension in @VERSION_1_12_7), @ref sip_reply_to "Reply-To" (extension in @VERSION_1_12_7), @ref sip_require "Require", @ref sip_retry_after "Retry-After", @ref sip_route "Route", @ref sip_server "Server", @ref sip_subject "Subject" ("s"), @ref sip_supported "Supported" ("k"), @ref sip_timestamp "Timestamp", @ref sip_to "To" ("t"), @ref sip_unsupported "Unsupported", @ref sip_user_agent "User-Agent", @ref sip_via "Via" ("v"), @ref sip_warning "Warning", and @ref sip_www_authenticate "WWW-Authenticate". Unknown headers (extension headers) are supported and can be passed to/received from application as name-value pairs. It is possible to extend SIP parser in run-time with header-specific parsers. - Automatic escaping of reserved characters has not been implemented. - Using NUL (zero byte) in double-quoted strings has not been implemented
@RFC3261 Section 18:
UDP and TCP transports 		UDP and TCP on both IP4 and IP6 are supported. The UDP size limit of 1300 bytes is enforced by default. If limit is exceeded, TCP is tried instead. If TCP connection is refused, UDP is tried if message size is less than 64 kilobytes. Limit is adjustable via parameter NTATAG_UDP_MTU(). TCP connections are reused by client. However, server closes connections after idle time of 30 minutes (by default). The idle time limit is adjustable with TPTAG_IDLE() (given as argument to nta_agent_add_tport() or nta_agent_create()). Server tries to use same TCP connection to return response as the request was received. Only one SIP message is accepted per UDP message, as per @RFC3261. There is experimental support for SCTP, too.
@RFC3261 Section 17:
Transactions 		Transaction state engines function as specified in @RFC3261 section 17. There is special handling of methods @b INVITE, @b ACK, and @b CANCEL. There are two modes for transaction state engines, User-Agent and Proxy modes. Default values for SIP timers are those specified by @RFC3261. The values for T1, T1x64, T2 and T4 can be changed via configuration tags defined in . The SIP timer C is implemented from @VERSION_1_12_7. Also, its value can be changed via configuration tag NTATAG_TIMER_C() defined in .  
@RFC3261 Section 26:
Security 		TLS and SIPS URIs has been implemented. Currently, TLS does not require certificate from client nor it does check it if one is provided. Missing: - Authorizing connections with TLS certificates - S/MIME
@RFC2617: HTTP Digest Authentication Sofia-SIP includes authentication client and server modules implementing HTTP Digest authentication. HTTP Digest is a simple challenge-response authentication scheme defined in @RFC2617 based on the UA sending a checksum calculated over specific values in response to a challenge sent by the server (proxy or UA). Checksum calculation supports MD5 (@RFC1321). The algorithm for calculating MD5 digest hash can be MD5, MD5sess or be @RFC2069-compatible algorithm. The quality-of-protection (qop) parameters "auth", "auth-int" and none (missing) are supported. The "opaque" parameter is supported. The SIP authentication headers supported (generating, parsing and syntax checking) are: @ref sip_authorization "Authorization", @ref sip_authentication_info "Authentication-Info", @ref sip_proxy_authenticate "Proxy-Authenticate", @ref sip_proxy_authentication_info "Proxy-Authentication-Info", @ref sip_proxy_authorization "Proxy-Authorization", and @ref sip_www_authenticate "WWW-Authenticate". SIP interface to the modules is implemented as defined in @RFC3261 (sections 8.1.3.5, 22.2, 22.3, 22.4). An @RFC2617 header @ref sip_proxy_authentication_info "Proxy-Authentication-Info" is not listed in @RFC3261 but it is nevertheless supported by Sofia-SIP. Missing: - Using nextnonce - Mutual authentication
@RFC3262: PRACK and 100rel PRACK method is supported within dialog as defined in RFC3262. Semantics of reliable provisional responses are supported: - including 100rel Required header in provisional responses if request had 100rel - generation of PRACK based on 100rel option tag in Require header of a provisional response, and - automatic re-transmission of provisional responses.

@RFC2806: tel URI Sofia-SIP supports handling of any URI type. Sofia-SIP parses tel: URIs. Missing: - Resolving the tel: URIs
@RFC2976: INFO INFO method is supported within a dialog natively. Not implemented: - Generating or processing contents of INFO requests
@RFC3311: UPDATE UPDATE method as defined in RFC3311. UPDATE allows a client to update parameters of a session (such as the set of media streams and their codecs) even within early dialogs. Offer-Answer negotiation with UPDATE is implemented in nua. Application must take care of: - Initiating UPDATE requests
@RFC3313: Media Authentication Sofia-SIP provides generic support for extension headers and parameters. P-Media-Authorization header is supported as an @ref sip_unknown "extension header". Application must take care of: - Passing the authorization token to QoS reservation request
@RFC3323: Privacy @ref sip_privacy "Privacy" header is supported (generating, parsing and syntax checking). Call-Id header is generated from cryptographically random id without host name or IP address. By default, @ref sip_contact "Contact" and @ref sip_via "Via" headers contain only IP address that can be dynamically allocated. Application can enter any SIP URI and display name to From header, e.g., @code Anonymous @endcode. Application must take care of: - Properly populating the URIs and display names within SIP headers - Not including any optional headers that could reveal identity - Generating of Privacy header with appropriate values - Generating of Proxy-Require: privacy - Using anonymous callback URIs etc.

Application must take care of: - Generating subscriptions for "reg" event - Processing notifications for "reg" event - Handling of XML document in notifications
@RFC3824: ENUM Tel URIs are supported in any headers including URI parameters, e.g., To, From, Contact headers, and Request-URI of the outgoing SIP request provided that the next hop is given as SIP or SIPS URI. Stack can not resolve E.164 number to address of next hop. A proxy in the network must resolve E.164 numbers with ENUM.
@RFC3840: Callee Capabilities Feature parameters can be added to SIP profiles and sent within Contact header of REGISTER request as header parameters. UAC can optionally generate media tags for Contact header using local media profile. Feature parameters can also be sent within any other SIP request as extension parameters of Contact header. Application must take care of: - Processing the feature parameters received in the Contact header
@RFC3841: Caller Preferences Built-in support for user-agent behavior. UAC can optionally generate Accept-Contact header using local media profile. SIP parser parses the Accept-Contact and Reject-Contact headers.

Referred-by token can be sent and received in text-based SIP message body. Application must take care of: - Generating or processing @ref sip_referred_by "Referred-By" headers - Generating (and encrypting) or verifying (and decrypting) of Referred-by tokens
@RFC3903: PUBLISH PUBLISH method is supported natively. The SIP headers explicitly supported (generating, parsing and syntax checking) are @ref sip_etag "SIP-ETag" and @ref sip_if_match "SIP-If-Match". The user-agent engine keep published data refreshed until nua_unpublish() is called. Application must take care of: - Including correct @ref sip_event "Event" in the request - Permanently storing @SIPETag
@RFC4028: Session Timers The SIP session-timer ("timer") extension is supported. The session-expires value and refreshing party is negotiated in user-agent engine. When user-agent engine is responsible for refreshes, it will initiate re-INVITE or UPDATE transaction at regular intervals. If there has been no SIP activity in session during the refresh period, it will try to automatically terminate the call by sending a @b BYE request. The SIP headers explicitly supported (generating, parsing and syntax checking) are @ref sip_session_expires "Session-Expires" ("x") and @ref sip_min_se "Min-SE".  
@RFC4168: SCTP as Transport for SIP The transport=sctp URI parameter is supported. The SCTP transport protocol is supported as experimental.

It is possible to send SIP messages smaller than 64K over SCTP.  
@RFC4320: Actions Addressing Identified Issues with SIP's Non-INVITE Transaction The action 1 (make the best use of provisional responses) is supported when NTATAG_EXTRA_100(1) is used with nua_create() or nta_agent_create(). The 100 Trying provisional response is sent after T2 is expired or when a retransmission is received after T2/2 after the initial request. The action 2 (remove the useless late-response storm) is supported by default. The 408 timeout response is not forwarded by default (it's forwarding can be enabled with NTATAG_PASS_408(1), however). Application must include NTATAG_EXTRA_100(1) with nua_create() or nta_agent_create() tags.
@RFC4488: Suppression of REFER Implicit Subscription Sofia-SIP supports @ref sip_refer_sub "Refer-Sub" header (generating, parsing and syntax checking). The implicit subscription is suppressed by @nua, if the @ReferSub: true header is included in the REFER request (@ref nua_refer "on server side") or response (@ref nua_i_refer "on client side"). @NEW_1_12_5 The REFER client application must include SIPTAG_REFER_SUB_STR("true") in the nua_refer() tags.
@RFC5057: Multiple Dialog Usages in SIP Sofia-SIP provides function sip_response_terminates_dialog() that can be used to determine the effect of error response with dialog. The nua UA engine uses sip_response_terminates_dialog(). The client application must either use NUA or sip_response_terminates_dialog().

Its home page is at http://www.doxygen.org. The Sofia documentation is written using Doxygen. Doxygen works by extracting the documentation data both from the actual C/C++ source code and from the specially formatted comments. The comments can contain some Javadoc-like @ref doxycommands "special commands". In general the the style of the comments and documentation should follow the javadoc style guide. A Doxygen comment must either contain reference about the entity it is describing, e.g., command \@file when describing files: @verbatim /** * @file foo.c * * Implementation of foo. The foo takes care of grokking xyzzy. * * @author Jaska Jokunen \n * * @date Created: Wed Oct 20 15:06:51 EEST 2004 jasjoku */ @endverbatim Usually the entity that is documented comes straight after the documentation comment. For example, documenting a function happens like this: @anchor orch @verbatim /** * Orches a candometer. If orching candometer is not possible, it * tries to schadule hearping. * * @param[in] k pointer to a candometer * @param[in] level orching level * @param[out] return_hearping return value for schaduled hearping * * @return * The function orch() returns the candometer value, or #ERROR upon an error. * If the returned value is 0, the newly schaduled hearping is returned in * @a return_hearping. */ int orch(cando_t *k, int level, hearping_t *return_hearping) { ... } @endverbatim @subsection doxyfile Doxyfile and Doxyfile.conf The doxygen options are specified through a configuration file, Doxyfile. As a convention, a module-specific Doxyfile includes a common file libsofia-sip-ua/docs/Doxyfile.conf. This makes it possible to keep the module-specific Doxyfiles as clean as possible: @code PROJECT_NAME = "ipt" OUTPUT_DIRECTORY = ../docs/ipt INPUT = ipt.docs . @INCLUDE = ../Doxyfile.conf TAGFILES += ../docs/docs/doxytags=../docs TAGFILES += ../docs/su/doxytags=../su GENERATE_TAGFILE = ../docs/ipt/doxytags @endcode From the file above, you can observe some conventions. The Doxygen-generated HTML documentation is collected in @b docs subdirectory at top level. A separate output directory is created for each submodule under it. Doxytags for the module are generated in the @e doxytags file in the output directory. @subsection module_docs Module documentation in \.docs Each module contains a documentation file containing at least the module mainpage called @e \.docs. There should be the module boilerplate information, for instance the following example is excerpt contents of file @e ipt.docs: @verbatim /** @MODULEPAGE "ipt" - Utility Module @section ipt_meta Module Meta Information Utility library for IP Telephony applications. @CONTACT Pekka Pessi @STATUS @SofiaSIP Core library @LICENSE LGPL @section ipt_overview Overview This module contain some routines useful for IPT applications, like - ... - ... */ @endverbatim @section doxycommands Common Doxygen Commands In this section we go through the most common Doxygen commands. All the commands are explained in the manual. The commands include - @ref doxystyle "style commands (@@a, @@b, @@c, @@e, @@em, @@p)" - @ref doxyfuncs "function parameters and return values (@@param, @@return, @@retval)" @subsection doxystyle Style Commands - @a, @b, @c, @e The text style can be changed with @@b @b (bold), @@c @c (code), or @@e @e (italic) commands. Function argument names use style command @@a. For example, a sentence "The @b Content-Type header @a ct specifies the @e media-type of the message body, e.g., @c audio/amr would be AMR-encoded audio." is produced with commands like @code The @b Content-Type header @a ct specifies the @e media-type of the message body, e.g., @c audio/amr would be AMR-encoded audio. @endcode The style commands have synonyms, e.g., @@em and @@e mean same, as well as @@c and @@p. @subsection doxyfuncs Function Parameters and Return Values - @param, @return, @retval Parameters to a function are documented with @@param commands. (See the @ref orch "orch()" function above.) As a convention, the data flow direction [in], [out] or [in,out] is indicated in the brackets after the @@param command keyword. Return values can be documented in two alternative manners, either using @@return command (see @ref orch "orch()") or @@retval command. The latter is used if the function returns a small number of possible values, e.g., enumeration or success/failure indication. @verbatim /**Schadule hearping. * * The function schadule() schadules a hearping. * * @param[in] h pointer to hearping * * @retval 0 hearping was successful * @retval -1 an error occurred */ int schadule(hearping_t *h) { ... } @endverbatim @subsection doxyexamples Example Blocks - @code, @endcode An example code fragment can be included using @@code and @@endcode commands. @verbatim /**Destroy a hearping. * * The function hearping_destroy() deinitializes a hearping and * reclaims the memory allocated for it. * * @param[in,out] h pointer to pointer to hearping * * The function clears the pointer to hearping, so it must be called * with a pointer to pointer: * @code * hearping_destroy(&x->hearping); * @endcode */ void hearping_destroy(hearping_t **h) { @endverbatim @subsection docpar Paragraphs The command @@par can be used to divide text into paragraphs. The text on the same line with @@par is used as a subtitle for the paragraph. The commands @@date, @@note, @@bug, @@todo, @@sa (See Also) and @@deprecated can be used to add common paragraphs to documentation entries. @subsection docfiles Documenting Files In most files there is documentation entry for the file itself. It is usually at top after the LGPL reference, containing @@file command or alias @@CFILE/@@IFILE. There are Emacs macros for creating the boilerplate entry. @subsection docgrouping Grouping Entries When the structure of the documentation does not follow directory or file structure, it is possible to use grouping commands @@defgroup and @@ingroup. The command @@defgroup creates a group, and @@ingroup adds an entry to an group. @subsection doclinking Creating Links Normally, Doxygen creates links to classes (and C structs) when it encounters the struct/class name. It is also possible to add links to functions, type names and variables. If the function name is followed by pair of parenthesis (), Doxygen creates a link to it. If a type name or variable is prefixed with hash @#, Doxygen creates a link to it. It is also possible to create links with freely selected link to documentation entries with @@link and @@endlink commands. When the link target is a named page, section, or subsection, it is possible to use the @@ref command. @subsection doctext Writing Body Text The main body of the documentation is specified with @@mainpage command. The contents of the @@mainpage entry become the HTML home page of the documentation set. In each documentation set generated with Doxygen there can be only one @@mainpage command. Commands @@section, @@subsection, and @@subsubsection can be used to structure the body text. It is also possible to add individual HTML pages to the documentation. It happens with @@page command. These individual pages are like the home page added with @@mainpage, they can be accessed with the Related Pages link from the navigation bar. @subsection docimages Adding Images Images are added with @@image command. As the different documentation formats support different image formats, the @@image has list the image file name for each supported documentation format. The following example uses bitmap image for HTML documentation and Encapsulate PostScript for print documents: @code @image html sip-parser.gif @image latex sip-parser.eps @endcode */ sofia-sip-1.12.11+20110422.1/libsofia-sip-ua/docs/mainpage.docs000066400000000000000000000627711223300710500231520ustar00rootroot00000000000000/* -*- text -*- */ /**@mainpage Sofia SIP User Agent Library - sofia-sip-ua @section Introduction This document contains automatically generated reference documentation for Sofia-SIP components.

The guidelines include identifier naming conventions, indenting convention, and tool usage directions. Please note that C style is always a matter of taste. @section naming Naming Conventions Generally, identifiers within each module are prefixed with the name of that module. For instance, the functions within http parser module @b http have prefix @c http_. Identifiers composed of multiple words have an underscore "_" between the words, the words themselves are in lower case. For instance, http_request_create(). Macros should be in upper case. File names should be in lower case using underscore as delimiter if needed. Normal typedefs have suffix @c _t, however, function types have suffix @c _f. The enum names also sometimes have @c _e, struct names have @c _s and union names @c _u. It is recommended that type itself is typedef'ed, not a pointer to the type. It should be clear from variable declaration if the variable is a pointer or not. @code typedef struct foo_s foo_t; typedef int f_fun(foo_t *f, char const *s); @endcode Struct and union members should have common prefix. For instance, @code struct foo_s { int f_len; char *f_name; fun_f *f_fun; }; @endcode This prefix makes it easier to find where members are used. @section formatting Indenting and Formatting code Indentation in Sofia-SIP C code generally follows the @e K&R style with indent of 2 characters (so you can use the default "GNU" c-style in Emacs). The maximum line length should be 80 characters. For example, @code void kluge(int foo) { if (foo) { bar(); } else { switch (baz()) { case a: eeny(); break; case b: meeny(); break; default: moe(); break; } } } @endcode The default indentation can be achieved with GNU indent with options @code -nbad -bap -bbo -nbc -br -brs -c33 -cd33 -ncdb -ce -ci2 -cli0 -cp33 -cs -d0 -di1 -nfc1 -nfca -hnl -i2 -ip0 -l79 -lp -npcs -nprs -npsl -saf -sai -saw -nsc -nsob -nss @endcode Loops without condition use @c for @c (;;) instead of @c while @c (1). @code for (;;) { foo(); if (bar()) break; baz(); } @endcode There should be whitespace on both sides of infix operators, except . or ->, which require no space, or , (comma) which requires space only after). There should be whitespace between a keyword and parenthesis following it, but no whitespace between an identifier and parenthesis following it. E.g., @code while (i++ < n) baz(); for (;;) { x->x_foo(); if (bar()) break; z.z_baz++; } return (13 * i); @endcode */ /** @page programming Programming Guide @section porting Writing Portable Code Most of Sofia-SIP software is written as portable. All core modules are (or at least should be) written in ANSI C 89 with some ANSI C 99 features. If there are platform specific parts, they are collected to separate C files and isolated from the rest of the software with a wrapper interface. SU module handles abstraction to OS specific functionality such as memory management, sockets, threads and time functions. @subsection ansi_99 ANSI C 99 features The following ANSI C 99 features are to be used in Sofia-SIP software: - Integer types - functions va_copy() and snprintf() The following ANSI C 99 features shall not be used in Sofia-SIP software: - definition of a variable in the middle of function code. (so always define your variables in the beginning of the block) @subsection port_ints Integer Types As you should know, the length of native storage size depends on hardware, OS and compiler. This means in practice that the length of int or long is not necessarily 32 bits. As a consequence, you need to make sure that the value you intend to store in the int, can actually fit in int on different platforms. As a rule of thumb, if the integer value can exceed 8 bits, you should use types that have a defined length. Nevertheless its OK to use native integer types if you bear in mind what was said above. The original reason for having only native data type was performance. The int type is always stored in the fastest (and usually biggest size) possible. Never assume anything on the length of the type. Alway use sizeof() operator to find out the length. C 99 standard defines the following fixed length data types: - int64_t - uint64_t - int32_t - uint32_t - int16_t - uint16_t - int8_t - uint8_t To use these data types you must include the header, which takes care of including correct file. If @b su includes are not available, you must include the following code segment to each file where you plan to use them: @code #if HAVE_STDINT_H #include #elif HAVE_INTTYPES_H #include #else #error Define HAVE_STDINT_H as 1 if you have , \ or HAVE_INTTYPES_H if you have #endif @endcode @subsection port_byte_sex Byte order The host byte order on different platforms vary. When you do only local processing, need not to worry about the byte order. But as soon as you start writing code that send or receives anything to the network, you need to start worrying. If you wish to convert the byte order, it is simply done by calling one the following functions: The htonl() function converts the unsigned integer hostlong from host byte order to network byte order. The htons() function converts the unsigned short integer hostshort from host byte order to network byte order. The ntohl() function converts the unsigned integer netlong from network byte order to host byte order. The ntohs() function converts the unsigned short integer netshort from network byte order to host byte order. You need to include or to use these functions. @subsection port_struct Packing structures By default, compilers usually arrange structures so that they are quick to access. This means that most fields in the structure start at the 32 bit boundary. If you need to conserve memory, you may use structure packing. To tell the compiler that you only need certain amount of bits to store a variable, you can use bit-fields. Compiler may or may not pack the bit-fields. @code struct foo { unsigned bar:5; unsigned foo:2; unsigned :0; int something; } @endcode If compiler decides to pack this structure, this code generates a structure that has @a bar and @a foo in the first seven bits, and then @a something beginning from the next 32 bit boundary. One problem arises when using packed bit-fields: on ARM it is generally not possible to access a 32 bit field that does not start from the 32-bit boundary. Hence the example has the :0 padding member in the structure. Seems handy but beware: initialization of this structure fails on some ARM gcc compilers. (Ask Kai Vehmanen for details). A way to force packing of a structure is to use preprocessor directive @c @#pragma(pack). This directive is compiler specific, so if you plan to write truly portable code, you cannot use it. We have used it in some parts of the Sofia-SIP though. Only alternative is to write functions that fetch the desired bits from a 32 bit field with bit operations; not very handy and error prone. The same aligment problem also arises if you cast for example char buffer to a int32_t. You can only read int32_t from the 32bit boundary on ARM platform. So be careful. As a conclusion, when using bit-fields and stucture packing, beware of the pitfalls. If you don't really need to use them (as in parsing binary protocols), don't use them. @section file_organization File and Directory Structure A Sofia-SIP library module can be defined as a subdirectory under the libsofia-sip-ua directory hierarchy that contains a file \.docs (where the \ of course referes to the actual name of the module). In case you like to start developing a new module, please contact Sofia-SIP development team so that they can help you to set up the basic module for you. An overview of the contents of a module directory: - file \.docs \n Main documentation file for the module. See @ref module_docs for more information - subdirectory pictures \n Contains any pictures/images that are needed by the module documentation. The file formats to use are GIF (for html pages) and EPS (for latex). If some program (e.g. MS Visio) is used to create the pictures, also the original files must be stored here.\n (Note that old modules may have "images" subdirectory instead of "pictures") - files Makefile.am \n See section @ref build "dealing with GNU Autotools" below. - (optionally) source code file(s) of the module and module tests. The source code file(s) can also be located in subdirectories if necesary. @section oo_with_c Writing Object-Oriented Code While C does not provide any special object-oriented features on its own, it is possible to program in object-oriented way using C, too. Sofia code make use of many object-oriented features while being written entirely in C. @subsection oo_hiding Data Hiding Data hiding is a practice that makes separation between two modules very clear. Outside code cannot directly access the data within a module, but it has to use functions provided for that purpose. Data hiding also makes it easier to define a protocol between two objects - all communication happens using function calls. How to implement data hiding in C? Easiest answer is to only declare data structures in the header files, not to define them. We have a typedef #msg_t for @link msg_s struct msg_s @endlink in , but the actual structure is defined in "msg_internal.h". Programs outside @b msg module does not have access to the @link msg_s struct msg_s @endlink, but they have to to access the #msg_t object through method functions provided in . The @b msg implementation is also free to change the internal layout of the structure, only keeping the function interface unmodified. @subsection oo_interface Interfaces Abstract interface is another object-oriented practice used in Sofia. Parser headers, defined in , is a good example of abstract interface. The type for message headers, #msg_header_t, is defined using two C structures @link msg_common_s struct msg_common_s @endlink (#msg_common_t), and @link msg_hclass_s struct msg_hclass_s @endlink (#msg_hclass_t). Abstract interface is achieved using virtual function table in #msg_hclass_t structure, bit like C++ typically implements abstract classes and virtual functions. For implemenation of each header, the function table is initialized with functions responsible for decoding, encoding and manipulating the header structure. Unlike C++, the class of the object (#msg_hclass_t) is represented by a real data structure which also contains header-specific data, like header name. @dontinclude sip_basic.c @skipline msg_hclass_t sip_contact_class @skip {{ @until }}; @subsection oo_derived Inheritance and Derived Objects Inheritance is a object-oriented practice that has limited use in Sofia. Most common example of inheritance is use of #su_home_t. Many objects are derived from #su_home_t, which means that they can use the various home-based memory management functions from . In this sence, inheritance means that a pointer to a derived object can be casted as a pointer to a base object. In other words, the derived object must have the base object at the beginning of its memory area: @code struct derived { struct base base[1]; int extra; char *data; }; @endcode There are three alternatives to cast a pointer to derived to a pointer to base: @code struct base *base1 = (struct base *)derived; struct base *base2 = &derived->base; struct base *base3 = derived->base; @endcode The third alternative works because base was used as a 1-element array. @subsection oo_templates Templates There are a few template types implemented as macros in Sofia libraries. They include hash table, defined in , which can be used to define hash tables types and accessor functions for different object, and red-black tree, defined in . @section memory Memory Management The home-based memory management is useful when a lot of memory blocks are allocated for given task. The allocations are done via the memory home, which keeps a reference to each allocated memory block. When the memory home is then freed, it will free all memory blocks to which it has reference. This simplifies application logic because application code does not need to keep track of the allocated memory and free every allocated block separately. See documentation of and @ref su_alloc "memory managment tutorial" for more information of memory management services. @subsection contextdata Memory management of context data A typical example of use of a memory home is to have a memory home structure (#su_home_t) as part of operation context information structure. @code /* context info structure */ struct context { su_home_t ctx_home[1]; /* memory home */ other_t *ctx_other_stuff; /* example of memory areas */ ... }; /* context pointer */ struct context *ctx; /* Allocate memory for context structure and initialize memory home */ ctx = su_home_clone(NULL, sizeof (struct context)); /* Allocate memory and register it with memory home */ ctx->ctx_other_stuff = su_zalloc(ctx->ctx_home, sizeof(other_t)); ... processing and allocating more memory ... /* Release registered memory areas, home, and context structure */ su_home_zap(ctx->ctx_home); @endcode @subsection combining Combining allocations Another place where home-based memory management makes programmers life easier is case where a sub-procedure makes multiple memory allocations and, in case the sub-procedure fails, all the allocations must be released and, in case the sub-procedure is succesfull, all allocations must be controlled by upper level memory management. @code /* example sub-procedure. top_home is upper-level memory home */ int sub_procedure( su_home_t *top_home, ... ) { su_home_t temphome[1] = { SU_HOME_INIT(temphome) }; ... allocations and other processing ... /* was processing successfull ? */ if (success) { /* ok -> move registered allocated memory to upper level memory home */ su_home_move( top_home, temphome ); } /* destroy temporary memory home (and registered allocations) */ /* Note than in case processing was succesfull the memory */ /* registrations were already moved to upper level home. */ su_home_deinit(temphome); /* return ok/not-ok */ return success; } @endcode @section testing Testing Your Code See for example of how to write module tests with macros provided by Sofia. Here are some ideas of what you should test: - "Smoke test" \n See that the module compiles, links and executes. - Module API functions should be tested with\n - valid args - not valid args - Aim for 100% line coverage\n (If there is a line of code that you have not tested, you don't know if its working.) \n For selected part of code you should also aim for 100% branch/path coverage.\n But be anyway reasonable with these because in practise complete coverage is next to impossible to achive (so 80% is ok in practise). - Create test to check assumptions and/or tricks used in code.\n For example if you rely on some compiler feature, create a test that will fail with a compiler that does not have that feature. @subsection check Running Module Tests Automake, which is used to build Sofia SIP, has builtin support for unit tests. To add an automatically run test to your module, you just have to add the following few lines to your module's Makefile.am (of course, you have to write the test programs, too): @code TESTS = test_foo test_bar check_PROGRAMS = test_foo test_bar test_foo_SOURCES = foo.c foo.h test_foo_LDADD = -L. -lmy test_bar_SOURCES = bar.c bar.h test_foo_LDADD = -L. -lmy @endcode Each test program should either return zero for success or a non-zero error code in its main function. Now when you run "make check", @b my_test_foo and @b my_test_bar will be built and then run. Make will print a summary of how the tests went. As these tests are run from the build system, the tests must be non-interactive (no questions asked) and not rely on any files that are not in version control system. Sofia SIP's top-level makefile contains a recursive check target, so you can use "cd sofia-sip ; make check" to run all the existing tests with a single command. @section build Dealing with GNU Autotools Sofia-SIP build system is based on the GNU tools automake, autoconf and libtool. This toolset has become the de-facto way of building Linux software. Because of this there is a lot of publicly available documentation about these tools, and of course, lots and lots of examples. A good introduction to these tools is available at developer.gnome.org. Autobook provides more detailed documentation for autoconf and automake. The GNU make manual is also a good source of information. @subsection autogen_sh autogen.sh At top-level there is a shell script called @b autogen.sh. It calls a convenient tool called @b autoreconf which will generate configure script for you. It also fixes the mode bits: the mode bits are not stored in darcs version control system. @code $ sh autogen.sh $ ./configure ... with your configure options ... @endcode @subsection configure_ac configure.ac The @b configure.ac file (older autoconf versions used also @b configure.in) contains the primary configuration for autoconf. configure.ac contains checks for all external libraries, non-standard language and compiler features that are needed to build the target module. This file is created by the developer of the module. @subsection sofia_m4 m4 files Sofia-SIP's own autoconf macros are stored in the top-level direcry called @b m4. These macros, along with all other macros used by @b configure.ac, are copied into the module-specific @b aclocal.m4 file by an utility called aclocal. Contact Sofia-SIP development team, if you need changes to these files. @subsection aclocal_m4 aclocal.m4 The aclocal.m4 contains the definitions of the autoconf macros used in @b configure.ac. This file is generated by aclocal command. @subsection Makefile_am Makefile.am Makefile.am is where you define what programs and libraries should be built, and also what source files are needed to create them. When you run automake, it creates the file Makefile.in. This file is created by the developer of the module. @subsection configure configure When you run configure script, it performs all the checks defined in @b configure.ac and then replaces all @b xxx.in files with equivalent @b xxx files. All @c @@FOO@@ variables in the source @b *.in files are replaced with values found during the configuration process. For instance the variable @c @@srcdir@@ in @b Makefile.in is replaced in @b Makefile with the source directory path (useful when compiling outside the main source tree). This file is generated by autoconf command. @subsection config_status config.status This script stores the last parameters given to configre command. If necessary you can rerun the last given configure script (with given parameters) by using command "./config.status -r" or "./config.status --recheck". This file is generated by configure script. @subsection config_cache config.cache This file contains results of the various checks that configure script performed. In case the configure script failed, you might try to delete this file and run the configure script again. This file is generated by configure script. @subsection Makefile Makefile The @b Makefile contains the actual rules how to build the target libraries and program. It is used by the @c make program. @b Makefile is generated from @b Makefile.in when you run @c autoconf command. Ensure that "make dist" and "make install" targets work. This file is generated by config.status and configure scripts. @subsection config_h config.h This file contains C language defines of various confurable issues. This file is generated by config.status and configure script. @subsection sofia_sip_configure_h sofia-sip/su_configure.h This file contains C language defines describing how the Sofia SIP UA library is configured. This file is generated by config.status and configure script. */ /** @page debug_logs Debugging Logs The Sofia-SIP components can output various debugging information. The detail of the debugging output is determined by the debugging level. The level is usually module-specific and it can be modified by module-specific environment variable. There is also a default level for all modules, controlled by environment variable #SOFIA_DEBUG. The environment variables controlling the logging and other debug output are as follows: - #SOFIA_DEBUG Default debug level (0..9) - #NUA_DEBUG User Agent engine (nua) debug level (0..9) - #SOA_DEBUG SDP Offer/Answer engine (soa) debug level (0..9) - #NEA_DEBUG Event engine (nea) debug level (0..9) - #IPTSEC_DEBUG HTTP/SIP autentication module debug level (0..9) - #NTA_DEBUG Transaction engine debug level (0..9) - #TPORT_DEBUG Transport event debug level (0..9) - #TPORT_LOG If set, print out all parsed SIP messages on transport layer - #TPORT_DUMP Filename for dumping unparsed messages from transport - #SU_DEBUG su module debug level (0..9) The defined debug output levels are: - 0 SU_DEBUG_0() - fatal errors, panic - 1 SU_DEBUG_1() - critical errors, minimal progress at subsystem level - 2 SU_DEBUG_2() - non-critical errors - 3 SU_DEBUG_3() - warnings, progress messages - 5 SU_DEBUG_5() - signaling protocol actions (incoming packets, ...) - 7 SU_DEBUG_7() - media protocol actions (incoming packets, ...) - 9 SU_DEBUG_9() - entering/exiting functions, very verbatim progress In addition to the macros mentioned above, there is also functions for printing logging messages: - su_llog(), su_vllog() - su_perror(), su_perror2() The log level can be set (to a level defined in a configuration file, for instance) with following functions - su_log_set_level(), su_log_soft_set_level() The log output can be redirected to, e.g., system log or loggin server, with su_log_redirect(). */

It also provides parsing of MIME headers and MIME multipart messages common to these protocols. @CONTACT Pekka Pessi @STATUS @SofiaSIP Core library @LICENSE LGPL @par Contributor(s): - Pekka Pessi @section msg_contents Contents of msg Module The msg module contains the public header files as follows: - base message interfaces - message and header struct definitions and typedefs - prototypes of header-specific functions for generic headers - function prototypes and macros for manipulating message headers - functions for accessing network addresses and I/O vectors associated with the message - types and functions for handling dates and times - types, function prototypes and macros for MIME headers and @ref msg_multipart "multipart messages" - prototypes of MIME-header-specific functions In addition to this interface, the @ref msg_parser "parser documentation" contains description of the functionality required when an existing parser is extended by a new header or a parser is created for a completely new protocol. It is possible to add new headers to the parser or extend the definition of existing ones. The header files used for constructing these parsers are as follows: - parsing functions, macros - message factory object definition - hashing of header names @section msg_overview Parsers, Messages and Headers The Sofia @b msg module contains interface to the text-based parsers for RFC822-like message, the header and message objects. Currently, there are three parsers defined: SIP, HTTP, and MIME. The C structure corresponding to each header is defined either in a or in a protocol-specific header file. These protocol-specific header files include , , and . For each header, there is defined a @em header @em class structure, some standard functions, and tags for including them in tag lists. As a convention, all the identifiers for SIP headers start with prefix @c sip and all the macros with @c SIP. Same thing holds for HTTP, too: it uses prefix @c http. However, the MIME headers and the functions related to them are defined within the @b msg module and they use prefix @c msg. If a SIP or HTTP header uses a structure defined in , there is a typedef suitable for the particular protocol, for example @b Accept header is defined multiple times: @code typedef struct msg_accept_s sip_accept_t; typedef struct msg_accept_s http_accept_t; @endcode For header @e X of protocol @e NS, there are types, functions, macros and header class as follows: - @c ns_X_t is the structure used to store parsed header, - @c ns_hclass_t @c ns_X_class[] contains the @em header @em class for header X, - @c NS_X_INIT() initializes a static instance of @c ns_X_t, - @c ns_X_init() initializes a dynamic instance of @c ns_X_t, - @c ns_is_X() tests if header object is instance of header X, - @c ns_X_make() creates a header X object by decoding given string, - @c ns_X_format() creates a header X object by decoding given @c printf() list, - @c ns_X_dup() duplicates (deeply copies) the header X, - @c ns_X_copy() copies the header X, - @c NSTAG_X() is used include instance of @c ns_X_t in a tag list, and - @c NSTAG_X_STR() is used to include string containing value header in a tag list. The declarations of header tags and the prototypes for these functions can be imported separately from the type definitions, for instance, the tags related to SIP headers are declared in the include file , and the header-specific functions in . @section parser_intro Parsing Text Messages Sofia text parser follows @em recursive-descent principle. In other words, it is a program that descends the syntax tree top-down recursively. (All syntax trees have root at top and they grow downwards.) In the case of SIP, HTTP and other similar protocols, such a parser is very efficient. The parser can choose between different forms based on each token, as the protocol syntax is carefully designed so that it requires only minimal scan-ahead. It is also easy to extend a recursive-descent parser via a standard API, unlike, for instance, a LALR parser generated by @em Bison. The abstract message module @b msg contains a high-level parser engine that drives the parsing process and invokes the protocol-specific parser for each header. As there is no low-layer framing between the RFC822-style messages, the parser considers any received data, be it a UDP datagram or a TCP stream, as a @em byte @em stream. The protocol-specific parsers controls how a byte stream is split into separate messages or if it consists of a single message only. The parser engine works by separating stream into fragments, then passing the fragment to a suitable parser. A fragment is a piece of message that is parsed during a single step: the first line, each header, the empty line between headers and message body, the message body. (In case of HTTP, the message body can consists of multiple fragments known as chunks.) The parser starts by separating the first line (e.g., request or status line) from the byte stream, then passing the line to the suitable parser. After first line comes the message headers. The parser continues parsing process by extracting headers, each on their own line, from the stream and passing contents of each header to its parser. The message structure is populated based on the parsing results. When an empty line - indicating end of headers - is encountered, the control is passed to the protocol-specific parser. Protocol-specific functions take care of extracting the possible message body from the byte stream. After parsing process is completed, it can be given to the upper layers (typically a protocol state machine). The parser continues processing the stream and feeding the messages to protocol engine until the end of the stream is reached. @image html sip-parser.gif Separating byte stream to messages @image latex sip-parser.eps Separating byte stream to messages When the parsing process has completed, the first line, each header, separator and the message body are all in their own fragment structure. The fragments form a dual-linked list known as @e fragment @e chain as shown in the above figure. The memory buffers for the message, the fragment chain, and a whole lot of other stuff is held by the generic message type, #msg_t, defined in . The internal structure of #msg_t is known only within @b msg module and it is opaque to other modules. The @b msg parser engine also drives the reverse process, invoking the encoding method of each fragment so that the whole outgoing message can be encoded properly. @section msg_header_struct Message Header as a C struct Just separating headers from each other and from the message body is not usually enough. When a header contains structured data, the header contents should be converted to a form that is convenient to use from C programs. For that purpose, the message parser needs a parsing function specific to each individual header. This parsing function divides the contents of the header into semantically meaningful segments and stores the result in the structure specific to each header. The parser engine passes the fragment contents to the parsing function after it has separated the fragment from the rest of the message. The parser engine selects correct @e header @e class either by implication (in case of first line), or it searches for the header class from the hash table using the header name as the hash key. The @e header @e class contains a pointer to the parsing function. The parser has also special header classes for headers with errors and @e unknown headers, header with a name that is not regocnized by the parser. For instance, the Accept header has following syntax: @code Accept = "Accept" ":" #( media-range [ accept-params ] ) media-range = ( "*" "/" "*" | ( type "/" "*" ) | ( type "/" subtype ) ) *( ";" parameter ) accept-params = ";" "q" "=" qvalue *( accept-extension ) accept-extension = ";" token [ "=" ( token | quoted-string ) ] @endcode When an Accept header is parsed, the header parser function (msg_accept_d()) separates the @e type, @e subtype, and each parameter in the list to strings. The parsing result is assigned to a #msg_accept_t structure, which is defined as follows: @code typedef struct msg_accept_s { msg_common_t ac_common[1]; //< Common fragment info msg_accept_t *ac_next; //< Pointer to next Accept header char const *ac_type; //< Pointer to type/subtype char const *ac_subtype; //< Points after first slash in type msg_param_t const *ac_params; //< List of parameters msg_param_t ac_q; //< Value of q parameter } msg_accept_t; @endcode The string containing the @e type is put into the @c ac_type field, the @e subtype after slash in the can be found in the @c ac_subtype field, and the list of @e accept-params (together with media-specific-parameters) is put in the @c ac_params array. If there is a @e q parameter present, a pointer to the @c qvalue is assigned to @c ac_q field. In the beginning of the header structure there are two boilerplate members. The @c ac_common[1] contains information common to all message fragments. The @c ac_next is a pointer to next header field with the same name, in case a message contains multiple @b Accept headers or multiple comma-separated header fields are located in a single line. @section msg_object_example Representing a Message as a C struct It is not enough to represent a message as a list of headers following each other. The programmer also needs a convenient way to access certain headers at the message level, for example, accessing directly the @b Accept header instead of going through all headers and examining their name. The structured view to the message is provided via a message-specific C struct. In general, its type is msg_pub_t (it provides public view to message). The protocol-specific type is #sip_t, #http_t or #msg_multipart_t for SIP, HTTP and MIME, respectively. So, a single message is represented by two objects, first object (#msg_t) is private to the @b msg module and opaque by an application programmer, second (#sip_t, #http_t or #msg_multipart_t) is a public protocol-specific structure accessible by all. @note The application programmer can obtain a pointer to the protocol-specific structure from an #msg_t object using msg_public() function. The msg_public() takes a protocol tag, a well-known identifier, as its argument. The SIP, HTTP and MIME already define a wrapper around msg_public(), for example, a #sip_t structure can be obtained with sip_object() function (or macro). As an example, the #sip_t structure is defined as follows: @code typedef struct sip_s { msg_common_t sip_common[1]; // Used with recursive inclusion msg_pub_t *sip_next; // Ditto void *sip_user; // Application data unsigned sip_size; // Size of the structure with // extension headers int sip_flags; // Parser flags sip_error_t *sip_error; // Erroneous headers sip_request_t *sip_request; // Request line sip_status_t *sip_status; // Status line sip_via_t *sip_via; // Via (v) sip_route_t *sip_route; // Route sip_record_route_t *sip_record_route; // Record-Route sip_max_forwards_t *sip_max_forwards; // Max-Forwards ... } sip_t; @endcode As you can see above, the public #sip_t structure contains the common header members that are also found in the beginning of a header structure. The @e sip_size indicates the size of the structure - the application can extend the parser and #sip_t structure beyond the original size. The @e sip_flags contains various flags used during the parsing and printing process. They are documented in the . These boilerplate members are followed by the pointers to various message elements and headers. @section msg_parsing_example Result of Parsing Process Let us now show how a simple message is parsed and presented to the applications. As an exampe, we choose a SIP request message with method BYE, including only the mandatory fields: @code BYE sip:joe@example.com SIP/2.0 Via: SIP/2.0/UDP sip.example.edu;branch=d7f2e89c.74a72681 Via: SIP/2.0/UDP pc104.example.edu:1030;maddr=110.213.33.19 From: Bobby Brown ;tag=77241a86 To: Joe User ;tag=7c6276c1 Call-ID: 4c4e911b@pc104.example.edu CSeq: 2 @endcode The figure below shows the layout of the BYE message above after parsing: @image html sip-parser2.gif BYE message and its representation in C @image latex sip-parser2.eps BYE message and its representation in C The leftmost box represents the message of type #msg_t. Next box from the left reprents the #sip_t structure, which contains pointers to a header objects. The next column contains the header objects. There is one header object for each message fragment. The rightmost box represents the I/O buffer used when the message was received. Note that the I/O buffer may be non-continous and composed of many separate memory areas. The message object has link to the public message structure (@a m_object), to the dual-linked fragment chain (@a m_frags) and to the I/O buffer (@a m_buffer). The public message structure contains pointers to the headers according to their type. If there are multiple headers of the same type (like there are two Via headers in the above message), the headers are put into a single-linked list. Each fragment has pointers to successing and preceding fragment. It also contains pointer to the corresponding data within the I/O buffer and its length. The main purpose of the fragment chain is to preserve the original order of the headers. If there were an third Via header after CSeq in the message, the fragment representing it would be after the CSeq header in the fragment chain but after second Via in the header list. @section msg_parsing_memory Example: Parsing a Complete Message The following code fragment is an example of parsing a complete message. The parsing process is more hairy when there is stream to be parsed. @code msg_t *parse_memory(msg_mclass_t const *mclass, char const data[], int len) { msg_t *msg; int m; msg_iovec_t iovec[2] = {{ 0 }}; msg = msg_create(mclass, 0); if (!msg) return NULL; m = msg_recv_iovec(msg, iovec, 2, n, 1); if (m < 0) { msg_destroy(msg); return NULL; } assert(m <= 2); assert(iovec[0].mv_len + iovec[1].mv_len == n); memcpy(iovec[0].mv_base, data, n = iovec[0].mv_len); if (m == 2) memcpy(iovec[1].mv_base + n, data + n, iovec[1].mv_len); msg_recv_commit(msg, iovec[0].mv_len + iovec[1].mv_len, 1); m = msg_extract(msg); assert(m != 0); if (m < 0) { msg_destroy(msg); return NULL; } return msg; } @endcode Let's go through this simple function, step by step. First, we get the @a data pointer and its size in bytes, @a len. We first initialize an I/O vector used to represent message with the parser. @code msg_t *parse_memory(msg_mclass_t const *mclass, char const data[], int len) { msg_t *msg; int m; msg_iovec_t iovec[2] = {{ 0 }}; @endcode The message class @a mclass (a parser driver object, #msg_mclass_t) is used to represent a particular protocol-specific parser instance. When a message object is created, it is given as an argument to msg_create() function: @code msg = msg_create(mclass, 0); if (!msg) return NULL; @endcode Next we obtain a memory buffer for data with msg_recv_iovec(). The memory buffer is usually a single continous memory area, but in some cases it may consist of two distinct areas. Therefore the @a iovec is used here to pass the buffers around. The @a iovec is also very handly as it can be directly passed to various system I/O calls. @code m = msg_recv_iovec(msg, iovec, 2, n, 1); if (m < 0) { msg_destroy(msg); return NULL; } @endcode These assumptions hold always true when you call msg_recv_iovec() first time with a complete message: @code assert(m >= 1 && m <= 2); assert(iovec[0].mv_len + iovec[1].mv_len == n); @endcode Next, we copy the data to the I/O vector and commit the copied data to the message. Earlier with msg_recv_iovec() we allocated buffer space for data, now calling msg_recv_commit() indicates that valid data has been copied to the buffer. The last parameter to msg_recv_commit() indicates that the end of stream is encountered and no more data is to be expected. @code memcpy(iovec[0].mv_base, data, n = iovec[0].mv_len); if (m == 2) memcpy(iovec[1].mv_base + n, data + n, iovec[1].mv_len); msg_recv_commit(msg, iovec[0].mv_len + iovec[1].mv_len, 1); @endcode We call msg_extract() next; it takes care of parsing the message. A fatal parsing error is indicated by returning -1. If the message is incomplete, msg_extract() returns 0. When a complete message has been parsed, a positive value is returned. We know that a message cannot be incomplete, as a call to msg_recv_commit() indicated to the parser that the end-of-stream has been encountered. @code m = msg_extract(msg); assert(m != 0); if (m < 0) { msg_destroy(msg); return NULL; } return msg; } @endcode */ /**@class msg_s msg.h * * @brief Message object. * * The message object is used by Sofia parsers for SIP and HTTP * protocols.

Note that the semantics of a part differ from the * semantics of a message, as described in the text.> * * encapsulation := delimiter transport-padding CRLF * body-part * * close-delimiter := delimiter "--" * * delimiter := CRLF dash-boundary * * epilogue := discard-text * * @endcode * * @par Parsing a Multipart Message * * When a message body contains a multipart entity (in other words, it has a * MIME media type of "multipart"), the application can split the multipart * entity into body parts * * The parsing is relatively simple, the application just gives a memory * home object, a Content-Type header object and message body object as an * argument to msg_multipart_parse() function: * @code * if (sip->sip_content_type && * su_casenmatch(sip->sip_content_type, "multipart/", 10)) { * msg_multipart_t *mp; * * if (sip->sip_multipart) * mp = sip->sip_multipart; * else * mp = msg_multipart_parse(msg_home(msg), * sip->sip_content_type, * (sip_payload_t *)sip->sip_payload); * * if (mp) * ... processing multipart ... * else * ... error handling ... * } * @endcode * * The resulting list of msg_multipart_t structures contain the parts of the * multipart entity, each part represented by a separate #msg_multipart_t * structure. Please note that in order to make error recovery possible, the * parsing is not recursive - if multipart contains another multipart, the * application is responsible for scanning for it and parsing it. * * @par Constructing a Multipart Message * * Constructing a multipart body is a bit more hairy. The application needs * a message object (#msg_t), which is used to buffer the encoding of * multipart components. * * As an example, let us create a "multipart/mixed" multipart entity with a * HTML and GIF contents, and convert it into a #sip_payload_t structure: * @code * msg_t *msg = msg_create(sip_default_mclass, 0); * su_home_t *home = msg_home(msg); * sip_t *sip = sip_object(msg); * sip_content_type_t *c; * msg_multipart_t *mp = NULL; * msg_header_t *h = NULL; * char *b; * size_t len, offset; * * mp = msg_multipart_create(home, "text/html;level=3", html, strlen(html)); * mp->mp_next = msg_multipart_create(home, "image/gif", gif, giflen); * * c = sip_content_type_make(home, "multipart/mixed"); * * // Add delimiters to multipart, and boundary parameter to content-type * if (msg_multipart_complete(home, c, mp) < 0) * return -1; // Error * * // Combine multipart components into the chain * h = NULL; * if (msg_multipart_serialize(&h, mp) < 0) * return -1; // Error * * // Encode all multipart components * len = msg_multipart_prepare(msg, mp, 0); * if (len < 0) * return -1; // Error * * pl = sip_payload_create(home, NULL, len); * * // Copy each element from multipart to pl_data * b = pl->pl_data; * for (offset = 0, h = mp; offset < len; h = h->sh_succ) { * memcpy(b + offset, h->sh_data, h->sh_len); * offset += h->sh_len; * } * @endcode * */ /**Create a part for MIME multipart entity. * * The function msg_multipart_create() allocates a new #msg_multipart_t * object from memory home @a home.

Interface used both in client and server sides * is presented in . * * @CONTACT Pekka Pessi * * @STATUS @SofiaSIP Core library * * @LICENSE LGPL * * @section Creating NEA server and events * * @section nea_server_create Creating NEA server * * NEA server generates, receives and sends events to subscribed * parties. The server is presentity specific, ie. a different server * is created for every presentity. * * First, a server object is created. The object uses the NTA @e agent * (#nta_agent_t) that handles incoming and outgoing SIP messages. * * The example below provides a way to create the NEA server. The * function nea_server_create() creates the server. Parameters @e * agent, @e root define the transaction engine. Third parameter is * the address of the presentity. event_callback is a callback * function pointer and is called every time a new user subscribes to * an event that does not exist or requests for payload type that * doesn't match. * * @code * presence_t *presence_create(su_root_t *root, * nta_agent_t *agent, * sip_contact_t const *m) * { * presentity_t *pr = su_home_clone(p->p_home, sizeof (*pr)); * ... * pr->pr_nes = * nea_server_create(agent, root, * m->m_url, * MAX_SUBSCRIBERS, * event_callback, pr, * SIPTAG_CONTACT(m), * SIPTAG_SERVER_STR("Sofia-SIP NEA"), * TAG_NULL()); * ... * } * @endcode * * @section nea_event_create Creating Events * * Next, events are created. The function nea_event_create () defines * an event, its package and content types (a comma separated * list). The parameter presence_callback defines the callback * function that is called when a someone subscribes to a defined * event. * * @code * #define PRESENCE_PACKAGE "presence" * #define XPIDF_MIME_TYPE "application/xpidf+xml" * #define PIDF_MIME_TYPE "application/cpim-pidf+xml" * ne = nea_event_create(pr->pr_nes, presence_callback, ep, * PRESENCE_PACKAGE, NULL, * PIDF_MIME_TYPE, * PIDF_MIME_TYPE "," XPIDF_MIME_TYPE); * @endcode * * @section nea_server_update Operating with event payloads * * A new payload can be inserted to a event with the function * nea_server_update(). The 4th parameter describes if the updated * content is a fake (for unauthorized subscribers). A real payload is * inserted (updated) with the 4th parameter being 0. If the event is * not updated with the content type @a ct before, a new content type * format for the event is created. Otherwise the old payload is * replaced with the new one. * * After the update, subscribers of the event are notified (with SIP * NOTIFY) of the changed payload with nea_server_update (). * * @code * nea_server_update(pr->pr_nes, home, event, 1, * SIPTAG_CONTENT_TYPE(ct), * SIPTAG_PAYLOAD(pl), * TAG_END()); * nea_server_notify(pr->pr_nes, event); * @endcode * * Obtaining the event's payload and removing it is presented in the * example below. The event is defined as a part of the @a package_t * structure. Function nea_payloads_get() is used to return a payload * (in this case content type being predefined * "application/cpim-pidf+xml"). The real and fake payloads are stored * in the structure #nea_payloads_t. Finally, the payload is removed * with nea_payload_remove(). * * @code * int remove_old_payload(package_t *ep) * { * nea_payloads_t *np; * sip_content_type_t *ct; * sip_payload_t *real; * sip_payload_t *fake; * event = ep->ep_event; * np = nea_payloads_get(event, PIDF_MIME_TYPE); * ct = nea_content_type_get(np); * real = nea_payload_get(np); * fake = nea_fake_get(np); * nea_payload_remove(ep->ep_home, np); * return 0; * } * @endcode */ sofia-sip-1.12.11+20110422.1/libsofia-sip-ua/nea/nea_debug.c000066400000000000000000000047731223300710500224050ustar00rootroot00000000000000/* * This file is part of the Sofia-SIP package * * Copyright (C) 2005 Nokia Corporation. * * Contact: Pekka Pessi * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public License * as published by the Free Software Foundation; either version 2.1 of * the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, but * WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[::] means that only * the IPv6 addresses are used. If a domain name or a specific IP address * is given as "host" part, an additional "maddr" parameter can be used to * control which addresses are used by the stack when binding listen * sockets for incoming requests. * * The "port" determines what port is used in contact, and to which port the * stack binds in order to listen for incoming requests. Empty or missing * port means that default port should be used (5060 for sip, 5061 for * sips). An "*" in "port" part means any port, i.e., the stack binds to an * ephemeral port. * * The "transport" parameter determines the transport protocol that is used * and how they are preferred. If no protocol is specified, both UDP and TCP * are used for SIP URL and TLS for SIPS URL. The preference can be * indicated with a comma-separated list of transports, for instance, * parameter @code transport=tcp,udp @endcode indicates that TCP is * preferred to UDP. * * The "maddr" parameter determines to which address the stack binds in * order to listen for incoming requests.

The @b nta interface is * intended for both network and user elements. The public interface for @b * nta is mostly defined in , but tag parameters are * defined in . * * @CONTACT Pekka Pessi * * @STATUS @SofiaSIP Core library * * @LICENSE LGPL * * @section nta_objects NTA Objects * * The NTA deals with a few kinds of objects: @e agent (#nta_agent_t), @e * call @e legs (#nta_leg_t), @e outgoing @e client @e requests * (#nta_outgoing_t), and @e incoming @e server @e requests * (#nta_incoming_t). * * NTA also uses SIP message objects #msg_t and #sip_t for handling * messages, as defined in and , * respectively. The various SIP headers are also defined in * . * * @section nta_agent_t Creating an NTA Agent * * Most of the SIP entities, like @e user @e agent or @e proxy, consist of a * SIP server and a SIP client working together. The NTA provides a simple * interface to SIP server and client with the #nta_agent_t objects. * * The #nta_agent_t object is created by calling nta_agent_create(). The * object listens for incoming connections, receives messages, parses them, * and pass them to the application. It also takes care of resolving the * domain names and sending the messages. * * The agent needs a #su_root_t object to schedule its execution. A root * object is used to wait for the network events, schedule the timer * routines, and pass messages asyncronously. A root object can be created * by, e.g., the function su_root_create(). The root object can be have its * own thread, or its main loop can be executed by an application thread by * calling the function su_root_run(). The main loop can be terminated by * calling the function su_root_break(). * * A simple agent could be created as follows: * @code * registrar->reg_root = su_root_create(NULL); * * if (registrar->reg_root) { * registrar->reg_agent = nta_agent_create(registrar->reg_root, * (url_string_t*)argv[1], * NULL, * NULL, * NULL); * * if (registrar->reg_agent) { * su_root_run(registrar->reg_root); * nta_agent_destroy(registrar->reg_agent); * } * * su_root_destroy(registrar->reg_root); * } * @endcode * * @section nta_server SIP Server Action * * A SIP server responds to the transactions sent by a client. The SIP * server can operate in two modes; it can be stateless or stateful. This * section describes how a stateful SIP server uses NTA. * * @subsection nta_leg_t The NTA Legs * * A leg is required for stateful transaction processing. A default * leg is created like this: * @code * default_leg = nta_leg_tcreate(agent, process_requests, context, * URLTAG_URL(url), * NTATAG_NO_DIALOG(1), * TAG_END()); * @endcode * * The @a url parameter is used to specify which URLs match to the leg. If * it is given, only requests with requestURI matching are processed by the * leg. The nta_leg_tcreate() is a @ref tagarg "tagarg" function, taking a * tagged argument list as its arguments. * * Other, ordinary legs can be used to match incoming requests with existing * dialogs, calls or transaction contexts, or to provide outgoing requests * with consistent headers. When a call leg is created, it is provided with * @From and @To headers, and optionally with other headers like * @CallID, @Route, or @CSeq. * * A new call leg can be created as follows: * @code * call_leg = nta_leg_tcreate(agent, * process_call_requests, call_context, * SIPTAG_CALL_ID(sip->sip_call_id), * SIPTAG_TO(sip->sip_from), * SIPTAG_FROM(sip->sip_to), * TAG_END()); * @endcode * * @note In the example above, the @From and @To are reversed. This * happens if the headers are taken from an incoming request; the @From * and @To headers change direction when an outgoing request is initiated. * * @note An existing leg can be used in any direction, however. If the leg * was created for an incoming INVITE transaction, it is also possible to * use the leg for an outgoing BYE transaction. * * @subsection nta_leg_tag Tagging the Call Leg * * All the SIP UAS elements are required to tag the @To header in their * final responses. The function nta_leg_tag() adds a tag to the leg's local * address. Local address is used as the @To header in the reply messages, * and as the @From header in the requests. The function nta_incoming_tag() * adds a tag to a incoming transaction. They are usually used in together, * using the tag from initial response to the dialog, too: * e.g., * @code * if (!nta_leg_tag(leg, nta_incoming_tag(irq, NULL))) * nta_incoming_treply(irq, SIP_500_INTERNAL_SERVER_ERROR, TAG_END()); * @endcode * * @subsection nta_incoming_t Incoming Transactions * * An incoming transaction object (nta_incoming_t) is created by NTA for * each unique incoming request message. When NTA has created the incoming * transaction object, it invokes the callback function provided with * nta_leg_tcreate(). * * The simplest way to reply to the request is to return a valid status code * from the callback function. Valid status codes are in range of 100 to * 699, inclusive. If no automatic response is desired, the callback * function should return 0. * * @note If the status code is final, the incoming transaction object will * be destroyed immediately after the callback function returns. It can not * be used afterwards. * * @note It is not possible to respond with a 2xx status code to an incoming * INVITE transaction by returning the status code from the callback. * * Valid return values for callback function are as follows: * @li 0, 100 .. 699 for requests other than INVITE, and * @li 0, 100 .. 199, 300..699 for INVITE requests. * * All other return codes are interpreted as 500, that is, a @e 500 @e * Internal @e Server @e Error reply message is sent back to the client and * the request is immediately destroyed. * * The simple registrar/redirect server may have a incoming request callback * as follows: * @code * int process_request(server_t *server, * nta_leg_t *leg, * nta_incoming_t *irq, * sip_t const *sip) * { * sip_contact_t *m; * * switch (sip->sip_request->rq_method) { * case sip_method_register: * return registrar_add(server, leg, reply, sip); * * case sip_method_ack: * return 500; * * case sip_method_cancel: * return 200; * * default: * if (registrar_find(server, sip->sip_request->rq_url, &m) { * nta_incoming_treply(irq, SIP_302_MOVED_TEMPORARILY, * SIPTAG_CONTACT(m), TAG_END()); * return 302; * } * else { * nta_incoming_treply(irq, SIP_404_NOT_FOUND, TAG_END()); * return 404; * } * } * } * @endcode * * The default reply message will contain the status line with default * phrase, then @Via, @To, @From, @CallID, @CSeq, and @ContentLength headers. * If a more complex response message is required, the application should * respond using the function nta_incoming_treply(): * @code * nta_incoming_treply(reply, SIP_200_OK, * SIPTAG_CONTACT(contact), * SIPTAG_CONTENT_TYPE_STR("application/sdp"), * SIPTAG_PAYLOAD(sdp), * TAG_END()); * @endcode * * The nta_incoming_treply() is a @ref tagarg "tagarg" function, taking a * tagged argument list as its argument. * * @note It is possible to send provisional replies (containing 1xx status * codes) several times with nta_incoming_treply(), but only one final * reply (containing status codes 2xx..6xx) can be sent. However, with * INVITE requests, a proxy can send a final 2xx reply even after an error * reply (3xx..6xx). * * @section nta_100rel Reliable Provisional Responses - "100rel" * * The 100rel SIP extension * provides reliable provisional responses, provisional responses that are * retransmitted until a special acknowledgement request, PRACK, is * received. In addition the PRACK method, the extension defines two * headers, @RSeq and @RAck, that are used to identify different * response messages. PRACK method is usable on INVITE requests only. * * Using reliable responses is negotiated using the "100rel" option tag. The * UAC (party sending the INVITE) can include the option tag to the * @Supported or @Require header. In the first case, the UAC just * announces support for reliable responses, in the second case, the UAC * requires that the UAS (party responding to the call) always sends * provisional responses in reliable manner. * * When reliable responses are enabled with NTATAG_REL100() tag, the @b nta * engine automatically inserts the "100rel" option tag to the @Supported * header in the INVITE requests. * * @subsection nta_reliable_t Responding Reliably * * When a UAS wants to respond reliably to a INVITE request, instead of * familiar nta_incoming_treply() or nta_incoming_mreply() it uses the * functions nta_reliable_treply() or nta_reliable_mreply(). These functions * return a pointer to a special object, nta_reliable_t, that is used to * keep track of unacknowledged responses and respond to the the PRACK * acknowledgement request. * * Both the functions nta_reliable_treply () and nta_reliable_mreply() take * a callback funtion pointer and an application context pointer as their * arguments. The callback function is similar to the leg callback function. * The callback is invoked when a corresponding PRACK request is received, * or when there is a timeout. * * The @b nta takes care of assigning a serial number to each reliable * response and resending them if no PRACK request is received. It also * automatically adds the 100rel option tag to the @Require header. * * Also, if a request with 100rel in @Require header is responded with usual * nta_incoming_treply()/nta_incoming_mreply() functions, the @b nta creates * a reliable response object for each provisional response in behalf of * application. As the application can not provide a PRACK callback function * to @b nta, the PRACK requests are not delivered to the application. * * @subsection early_dialog UAC Receives a Reliable Response * * When a UAC receives a provisional response with a @RSeq header, it is * required to acknowledge it. In order to do that, it must establish an @e * early @e dialog with the UAS. In another view, a reliable response is * used to establish the early dialog. UAC establishes a leg object for the * early dialog by calling nta_leg_tcreate() with the parameters derived * from the response message. * * @code * int invite_callback(call_t *call, * nta_outgoing_t *orq, * sip_t const *sip) * { * int status = sip->sip_status->st_status; * * if (!call->has_dialog && * (status >= 200 || (status > 100 && sip->sip_rseq))) { * nta_leg_t *early = * nta_leg_tcreate(call->nta_agent, mid_dialog_request, call, * SIPTAG_TO(sip->sip_to), * SIPTAG_FROM(sip->sip_from), * SIPTAG_CALL_ID(sip->sip_call_id), * SIPTAG_CSEQ(sip->sip_cseq), * TAG_END()); * * nta_leg_client_route(early, * sip->sip_record_route, * sip->sip_contact); * * fork = call_fork(call, leg = early); * * if (!fork){ * handle error; * } * call = fork; * } * @endcode * * The original dialog object and client transaction object are used to * process other call forks. For instance, if the early dialog is * established with an announcement server it will never lead to an fully * established call, but an another dialog will be used when the call is * completed. * * @subsection nta_prack Acknowledging Reliable Response * * After an early dialog has been established, acknowledging the reliable * response is trivial. The application can create a PRACK client * transaction object by calling nta_outgoing_prack() * * @section nta_client SIP Client Action * * A SIP client initiates the transactions. In some cases, a SIP client is * also required to invoke additional transactions, like @b ACK or @b * CANCEL, to finalize the original transaction. This section describes how * a SIP client uses NTA to make transactions. * * @subsection client_nta_leg_t Creating the Call Leg * * If the client does not have a suitable call leg, it must create it by * calling the function nta_leg_tcreate(): * @code * context->leg = nta_leg_tcreate(agent, * callback, context, * SIPTAG_CALL_ID(call_id), * SIPTAG_FROM(from), * SIPTAG_TO(to), * TAG_END()); * @endcode * * The @p callback function and @p context pointer are used for incoming * transactions, and they may be @c NULL if no such transactions are * expected. If the callback is @c NULL, NTA responds to incoming * transactions with status @e 403 @e Forbidden. * * The @a call_id may be @c NULL or left out. In that case, NTA generates a * new call ID. * * The @a from and @a to are used in outgoing transactions. They are also * used to select which incoming messages belong to this leg. * * The initial sequence number can be supplied with SIPTAG_CSEQ() (taking a * @CSeq structure as parameter). * * The additional parameters (after @a to) are included in outgoing messages * using this leg. Currently, only @c SIPTAG_ROUTE() is supported. * * @note Additional tagged parameters are ignored. * * @subsection nta_outgoing_t Outgoing requests * * The outgoing request is created and sent by nta_outgoing_tcreate(). It * can be used as follows: * @code * oreq = nta_outgoing_tcreate(leg, response_to_register, reg, * proxy_url, * SIP_METHOD_REGISTER, * registrar_url, * SIPTAG_CONTACT(my_contact), * TAG_END()); * @endcode * * NTA invokes the callback function response_to_register() each time a * provisional answer is received, and when a final answer is received. * * @note There may be multiple final answers to the INVITE request. * * If NTA does not receive answer in timely manner, it will generate a * @e 408 @e Timeout response and hand that back to the application. * * @note After a provisional answer to the INVITE request, no timeout will * occur inside NTA. Application must itself timeout the INVITE * transactions if any answer has been received. * * The request can be destroyed with NTA function nta_outgoing_destroy(). * If no final answer has been received, the request is cancelled when it is * destroyed, too. The application can also cancel the outgoing request by * calling nta_outgoing_cancel(). * * @subsection nta_ack Acknowledging Answers to INVITE * * The final answers to the INVITE request must be acknowledged. NTA takes * care of acknowledging automatically the 3xx..6xx answers; the appliction * must explicitly create a separate acknowledge transaction to final 2xx * answers. * * The final answer can be acknowledged like this: * @code * url = sip->sip_contact ? sip->sip_contact->m_url : original_url; * ack = nta_outgoing_tcreate(leg, NULL, NULL, * SIP_METHOD_ACK, * (url_string_t*)url, * SIPTAG_CSEQ(sip->sip_cseq), * SIPTAG_PAYLOAD(sdp), * TAG_END()); * @endcode * * @note The ACK transaction should be sent to the @Contact specified in the * 2xx reply. * * * @section nta_stateless_callback Stateless Processing of SIP Messages * * When an NTA agent is created, it is possible to provide it with a * stateless callback function. The callback function will be called when an * incoming SIP request or response message does not match with an existing * transaction. * * Before invoking the stateless callback the agent will try to match the * incoming request message with an existing dialog or dialog-less leg (or * default leg). So, if you have created a default leg, all request messages * are processed statefully by it instead of being passed to the stateless * callback function. * * If you want to process request messages with stateless callback and still * use dialog-less legs (for instance, in order to look up domains with * nta_leg_by_uri()), you have to switch over to @em stateless @em mode by * including NTATAG_STATELESS(1) in nta_agent_create() or * nta_agent_set_params() arguments. * * Also, if a response message does not match with an existing client * transaction, the agent will try to use the default outgoing (client) * transaction. If you have created an default outgoing transaction, all * stray response messages are passed to it instead of the stateless * processing function. * * @section nta_message_f_example Stateless Callback Function * * In addition to the message (@a msg) and its * parsed contents (@a sip) the callback function gets the * application-specific context pointer (in this case, @a registrar) and a * pointer to the NTA agent (@a agent) as its arguments: * * @code * int process_message(nta_agent_context_t *registrar, * nta_agent_t *agent, * msg_t *msg, * sip_t *sip); * @endcode * * The application has three functions that can be used to process the * messages in stateless manner: * @li nta_msg_discard() ignores and destroys the message, * @li nta_msg_tsend() forwards a request or response message, and * @li nta_msg_treply() replies to a request message in a stateless way. * * Additionally, it is possible to process a request message statefully with * nta_incoming_create(). * * The functionality of the stateless callback function can vary greatly, * depending the purpose of the application. An user-agent, a proxy or a * registrar/redirect server each have very different callback functions. * * A simple redirect server could have a message callback function as * follows. * * @code * int process_message(redirect_t *r, * nta_agent_t *agent, * msg_t *msg, * sip_t *sip) * { * sip_contact_t *m; * sip_unsupported_t *u; * * @endcode * * The incoming response messages are simply ignored. The @b ACK requests can * safely be discarded, too, because the redirect server keeps no state. * * @code * if (!sip->sip_request || sip->sip_request->rq_method == sip_method_ack) { * nta_msg_discard(agent, msg); * return 0; * } * @endcode * * Next, the redirect server first checks if processing the request requires * a feature that is not supported by it: * @code * u = sip_unsupported(msg_home(msg), sip->sip_require, r->r_supported); * if (u) { * nta_msg_treply(agent, msg, SIP_420_BAD_EXTENSION, * SIPTAG_SUPPORTED(r->r_supported), * SIPTAG_UNSUPPORTED(u), * TAG_END()); * return 0; * } * @endcode * * The @b CANCEL requests terminate a transacton. A stateless redirect * server does not have transactions, so it redirect replies with a @e 481 * @e Call @e Leg/Transaction @e Does @e Not @e Exist message: * @code * if (sip->sip_request->rq_method == sip_method_cancel) { * nta_msg_treply(agent, msg, SIP_481_NO_TRANSACTION, TAG_END()); * return 0; * } * @endcode * * All other requests are answered normally with a 302 response. * The location service is * searched for the request uri, and if a matching address was found, a * list of active bindings is returned to the client. * @code * m = location_find(redirect, sip->sip_request->rq_url); * if (m) { * nta_msg_treply(agent, msg, SIP_302_MOVED_TEMPORARILY, * SIPTAG_CONTACT(m), * TAG_END()); * } * @endcode * * Otherwise, @e 404 @e Not @e Found is sent: * @code * else { * nta_msg_treply(agent, msg, SIP_404_NOT_FOUND, TAG_END()); * } * * return 0; * } * @endcode * */ /**@page internal NTA Semantics and Internal Data Flows * * NTA implements simple state machines at transaction level.

Its functionality includes call management, messaging and event retrieval. @CONTACT Pekka Pessi @STATUS @SofiaSIP Core library @LICENSE LGPL @par Contributor(s): - Pekka Pessi - Pasi Rinne-Rahkola - Kai Vehmanen - Martti Mela @section nua_overview Overview The NUA API gives the high-level application programmer transparent and full control to the SIP protocol enginebelow it. NUA provides the call semantics on top of existing transaction semantics found in nta module. With NUA it is possible to create different kind of SIP User Agents, like terminals, gateways or MCUs. The @b nua engine hides many low-level signaling and media management aspects from the application programmer. It is possible to use different kind of media interfaces - even remote ones - in a fully transparent way. The application and the protocol engine within User Agent library can be run in separate threads. The protocol engine communicates with the application using @ref nua_event_e "events", delivered to the application with a a callback function. The callback function is called within the thread context of the application, represented with a #su_root_t object. @section nua_concepts_user Sofia Concepts for NUA User @subsection nua_intro Introduction The Sofia software suite is based on certain basic ideas and concepts that are used in all levels of Sofia software. Many of those are implemented in Sofia utility library (su) providing unified interface to the most important OS services and utilities . The following sections contain descriptions of the concepts that a user of NUA library must understand to create a working application. The other utilities (in the SU library and other libraries of Sofia software suite) might also be useful for an application developer but one must be careful when using them because they might change the behavior of the Sofia software suite in a way that causes NUA library to work incorrectly. See [su] for more detailed description of the SU services. @subsection nua_root Event loop - root object The NUA uses the reactor pattern (also known as dispatcher pattern and notifier pattern) for event driven systems (see [Using Design Patterns to Develop Reusable Object-oriented Communication Software, D.C. Schmidt, CACM October '95, 38(10): 65-74]). Sofia uses a task as basic execution unit for the programming model. According to the model, the program can ask that the event loop invokes a callback function when a certain event occurs. Such events include I/O activity, timers or a asynchronously delivered messages from other task. The root object is a handle representing the task in the application. Another way of seeing the same thing is that the root object represents the main event loop of the task. Through the root object the task code can access its context information (magic) and thread-synchronization features like wait objects, timers, and messages. An application using NUA services must create a root object and the callback routine to handle @ref nua_event_e "NUA events". The root object is created with su_root_create() function and the callback routine is registered with nua_create() function. Root object has type #su_root_t. See documentation of and for more information of root object. See section #nua_event_e for more information of the callback function. @subsection nua_magic Magic The magic is a term used for the context pointer that can be bound to various objects in Sofia stack (for example root object and operation handle) by the application code. This context pointer is passed back to the application code when a registered callback function is called by the main event loop. The Sofia stack retains the context information between calls to the callback function. An application can use the context information to store any information it needs for processing the events. @subsection nua_memmgmt Memory Handling The home-based memory management is useful when a lot of memory blocks are allocated for given task. The allocations are done via the memory home, which keeps a reference to each allocated memory block. When the memory home is then freed, it will free all memory blocks to which it has reference. This simplifies application logic because application code does not need to keep track of the allocated memory and free every allocated block separately. An application using NUA services can use the memory management services provided by the SU library but it is not mandatory. See documentation of for more information of memory management services. @subsection nua_tags Tags Tagging is the mechanism used in Sofia software for packing parameters to functions. It enables passing a variable number of parameters having non-fixed types. For an application programmer the tagging is visible as macros that are used to encapsulate the passed parameters. When evaluated a tagging macro creates a structure that contains a tag (telling what is the type of a parameter) and a value (pointer to opaque data). By checking the tag the layers of Sofia software check whether they can handle the parameter or should it just be passed to lower layers for processing. There are some tags with special meaning: - TAG_NULL() (synonymous to TAG_END()) end of tag list - TAG_SKIP() empty tag item - TAG_NEXT() tag item pointing to another tag list, ends the current tag list - TAG_ANY() filter tag accepting any tag - TAG_IF() conditional inclusion of tag item The NUA functions can be called with a list of tagged values if they have following parameters at the end of parameter list: @code tag_type_t tag, tag_value_t value, ...); @endcode The last tagged value on the parameter list must be TAG_NULL() (or TAG_END(), synonym for TAG_NULL()). Every tag has two versions: \n NUTAG_ \n which takes a value parameter and \n NUTAG__REF \n which takes a reference parameter. The latter is used with tl_gets() function to retrieve tag values from tag list. For SIP headers there exists also additional version of tags: \n SIPTAG__STR \n This tag version takes a C-language character string as parameter. The corresponding tag without _STR suffix takes a parsed value structure as parameter. The following is an example of call to NUA function containing tagged values: @code nua_unregister(op->op_handle, TAG_IF(use_registrar, NUTAG_REGISTRAR(registrar)), SIPTAG_CONTACT_STR("*"), SIPTAG_EXPIRES_STR("0"), TAG_NULL()); @endcode An application using NUA services must use tagged arguments for passing the parameters to functions. See nua_invite() for discussion on how a SIP message is constructed from the tags. See documentation of for more information of tags and the module-specific documentation of each Sofia module for information of tags specific for that module. @subsection nua_debugandlogging Debugging and Logging The modules of Sofia stack contain configurable debugging and logging functionality based on the services defined in . The debugging and logging details (for example level of details on output and output file name) can be configured by environment variables, directives in configuration files and compilation directives in the source files. Examples of useful directives/ environment variables are: - #SOFIA_DEBUG Default debug level (0..9) - #NUA_DEBUG NUA debug level (0..9) - #NTA_DEBUG Transaction engine debug level (0..9) - #TPORT_DEBUG Transport event debug level (0..9) - #TPORT_LOG If set, print out all parsed SIP messages on transport layer - #TPORT_DUMP Filename for dumping unparsed messages from transport The defined debug output levels are: - 0 fatal errors, panic - 1 critical errors, minimal progress at subsystem level - 2 non-critical errors - 3 warnings, progress messages - 5 signaling protocol actions (incoming packets, ...) - 7 media protocol actions (incoming packets, ...) - 9 entering/exiting functions, very verbatim progress An application using NUA services can also use the debugging and logging services provided by the Sofia stack but it is not mandatory. See documentation of for more information of debugging and logging services. @section nua_concepts NUA Concepts @subsection nua_stackobject NUA Stack Object Stack object represents an instance of SIP stack and media engine. It contains reference to root object of that stack, user-agent-specific settings, and reference to the SIP transaction engine, for example. A NUA stack object is created by nua_create() function and deleted by nua_destroy() function. The nua_shutdown() function is used to gracefully release active the sessions by @b nua engine. NUA stack object has type nua_t. @subsection nua_operationhandle NUA Operation Handle Operation handle represents an abstract SIP call/session. It contains information of SIP dialog and media session, and state machine that takes care of the call, high-level SDP offer-answer protocol, registration, subscriptions, publications and simple SIP transactions. An operation handle may contain list of tags used when SIP messages are created by NUA (e.g. From and To headers). An operation handle is created explicitly by the application using NUA for sending messages (function nua_handle()) and by stack for incoming calls/sessions (starting with INVITE or MESSAGE). The handle is destroyed by the application using NUA (function nua_handle_destroy()). Indication and response events are associated with an operation handle. NUA operation handle has type nua_handle_t. @subsection nua_stacktread Stack Thread and Message Passing Concepts The stack thread is a separate thread from application that provides the real-time protocol stack operations so that application thread can for example block or redraw UI as it likes. The communication between stack thread and application thread is asynchronous. Most of the NUA API functions cause a send of a message to the stack thread for processing and similarly when something happens in the stack thread it sends a message to the application thread. The messages to the application thread are delivered as invokes of the application callback function when the application calls su_root_run() or su_root_step() function. @subsection nua_sip_message SIP Message and Header Manipulation SIP messages are manipulated with typesafe SIPTAG_ tags. There are three versions of each SIP tag: - SIPTAG_() takes a parsed value as parameter. - SIPTAG__STR() takes an unparsed string as parameter. - SIPTAG__REF() takes a reference as parameter, is used with tl_gets() function to retrieve tag values from tag list. - SIPTAG___STR_REF() takes a reference as parameter, is used with tl_gets() function to retrieve string tag values from tag list. For example a header named "Example" would have tags names SIPTAG_EXAMPLE(), SIPTAG_EXAMPLE_STR(), and SIPTAG_EXAMPLE_REF(). When tags are used in NUA calls the corresponding headers are added to the message. In case the header can be present only once in a message and there already exists a value for the header the value given by tag replaces the existing header value. Passing tag value NULL has no effect on headers. Passing tag value (void *)-1 removes corresponding headers from the message. For example: - sending a SUBSCRIBE with @b Event: header and two @b Accept: headers: @code nua_subscribe(nh, SIPTAG_EVENT_STR("presence"), SIPTAG_ACCEPT(accept1), SIPTAG_ACCEPT(accept2), TAG_END()); @endcode - fetching tag values when processing nua_r_subscribe event: @code sip_accept_t *ac = NULL; sip_event_t *o = NULL; tl_gets(tl, SIPTAG_EVENT_REF(o), /* _REF takes a reference! */ SIPTAG_ACCEPT_REF(ac), TAG_END()); @endcode @section nua_tutorial SIP/NUA tutorial This section describes basic usage scenarios of NUA/Sofia stack using message sequence charts. @subsection nua_outgoingcall Outgoing Call @image latex SIP_outgoing_call.eps @image html SIP_outgoing_call.gif @subsection nua_incomingcall Incoming Call @image latex SIP_incoming_call.eps @image html SIP_incoming_call.gif @subsection nua_basicoutgoingoperation Basic Outgoing Operation @image latex SIP_basic_outgoing_operation.eps @image html SIP_basic_outgoing_operation.gif @subsection nua_basicincomingoperation Basic Incoming Operation @image latex SIP_basic_incoming_operation.eps @image html SIP_basic_incoming_operation.gif @subsection nua_outgoingoperationwithauth Outgoing Operation with Authentication @image latex SIP_outgoing_operation_with_auth.eps @image html SIP_outgoing_operation_with_auth.gif @section nua_simpleapplication Simple Application The following sections will present code examples from a simple application that uses services of NUA. The example is not complete but should present all relevant details of the basic use of NUA. On sourceforge.net there is available an example application sofisip_cli.c that can be studied for more complete example. @subsection nua_datastructures Data Structures & Defines An application using services of NUA normally defines data areas that are used to store context information (i.e., "magic"). The types of pointers to these context information areas are passed to NUA by defines. @code /* type for application context data */ typedef struct application application; #define NUA_MAGIC_T application /* type for operation context data */ typedef union oper_ctx_u oper_ctx_t; #define NUA_HMAGIC_T oper_ctx_t @endcode The information area contents themselves can be defined as C structures or unions: @code /* example of application context information structure */ typedef struct application { su_home_t home[1]; /* memory home */ su_root_t *root; /* root object */ nua_t *nua; /* NUA stack object */ /* other data as needed ... */ } application; /* Example of operation handle context information structure */ typedef union operation { nua_handle_t *handle; /* operation handle / struct { nua_handle_t *handle; /* operation handle / ... /* call-related information */ } call; struct { nua_handle_t *handle; /* operation handle / ... /* subscription-related information */ } subscription; /* other data as needed ... */ } operation; @endcode NUA stack object and handle are opaque to the application programmer. Likewise, the application context is completely opaque to the NUA stack module. NUA functions are passed a pointer, and that pointer is then given back to the application within the callback parameters. In this case the application context information structure is also used to store a root object and memory home for memory handling. The application context information also contains the NUA stack object information. @subsection nua_initanddeinit Initialization and deinitialization The following code is an example of application function that initializes the system, enters the main loop for processing the messages, and, after message processing is ended, deinitalizes the system. If the application is not just responding to incoming SIP messages there must also be means to send messages to NUA. This can be handled for example by having a separate thread that calls NUA functions to send messages or by having a socket connection to the application for sending commands to the application (see documentation of su_wait_create() and su_root_register()). @code /* Application context structure */ application appl[1] = {{{{(sizeof appl)}}}}; /* initialize system utilities */ su_init(); /* initialize memory handling */ su_home_init(appl->home); /* initialize root object */ appl->root = su_root_create(appl); if (appl->root != NULL) { /* create NUA stack */ appl->nua = nua_create(appl->root, app_callback, appl, /* tags as necessary ...*/ TAG_NULL()); if (appl->nua != NULL) { /* set necessary parameters */ nua_set_params(appl->nua, /* tags as necessary ... */ TAG_NULL()); /* enter main loop for processing of messages */ su_root_run(appl->root); /* destroy NUA stack */ nua_destroy(appl->nua); } /* deinit root object */ su_root_destroy(appl->root); appl->root = NULL; } /* deinitialize memory handling */ su_home_deinit(appl->home); /* deinitialize system utilities */ su_deinit(); @endcode @subsection nua_handlingevents Handling events Handling of the events coming from NUA stack is done in the callback function that is registered for NUA stack with the nua_create() function when the application is initialized. The content of callback function is in its simplest form just a switch/case statement that dispatches the incoming events for processing to separate functions. @code void app_callback(nua_event_t event, int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { switch (event) { case nua_i_invite: app_i_invite(status, phrase, nua, magic, nh, hmagic, sip, tags); break; case nua_r_invite: app_r_invite(status, phrase, nua, magic, nh, hmagic, sip, tags); break; /* and so on ... */ default: /* unknown event -> print out error message */ if (status > 100) { printf("unknown event %d: %03d %s\n", event, status, phrase); } else { printf("unknown event %d\n", event); } tl_print(stdout, "", tags); break; } } /* app_callback */ @endcode @subsection nua_placeacall Place a call The following three functions show an example of how a basic SIP call is created. The place_a_call() function creates an operation handle and invokes the SIP INVITE method. @code operation *place_a_call(char const *name, url_t const *url) { operation *op; sip_to_t *to; /* create operation context information */ op = su_zalloc(appl->home, (sizeof *op)); if (!op) return NULL; /* Destination address */ to = sip_to_create(NULL, url); if (!to) return NULL; to->a_display = name; /* create operation handle */ op->handle = nua_handle(appl->nua, op, SIPTAG_TO(to), TAG_END()); if (op->handle == NULL) { printf("cannot create operation handle\n"); return NULL; } nua_invite(op->handle, /* other tags as needed ... */ TAG_END()); } /* place_a_call */ @endcode The app_r_invite() function is called by callback function when response to INVITE message is received. Here it is assumed that automatic acknowledge is not enabled so ACK response must be sent explicitly. @code void app_r_invite(int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { if (status == 200) { nua_ack(nh, TAG_END()); } else { printf("response to INVITE: %03d %s\n", status, phrase); } } /* app_r_invite */ @endcode The nua_i_state event is sent (and app_i_state() function called by callback function) when the call state changes (see @ref nua_uac_call_model "client-side call model"). @code void app_i_state(int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { nua_callstate_t state = nua_callstate_init; tl_gets(tags, NUTAG_CALLSTATE_REF(state), NUTAG__REF(state), state = (nua_callstate_t)t->t_value; printf("call %s\n", nua_callstate_name(state)); } /* app_i_state */ @endcode @subsection nua_receiveacall Receive a call The app_i_invite() function is called by callback function when incoming INVITE message is received. This example assumes that autoanswer is not enabled so the response must be sent explicitly. @code void app_i_invite(int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { printf("incoming call\n"); nua_respond(nh, 200, "OK", SOA_USER_SDP(magic->sdp), TAG_END()); } /* app_i_invite */ @endcode The app_i_state() function is called by the callback function when call has been successfully set up and the media has been activated. @code void app_i_active(int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { printf("call active\n"); } /* app_i_active */ @endcode @subsection nua_terminatingcall Terminating a call The following three functions show an example of how a basic SIP call is terminated. The terminate_call() function sends the SIP BYE message. @code void terminate_call(void) { nua_bye(op->handle, TAG_END()); } /* terminate call */ @endcode The app_r_bye() function is called by the callback function when answer to the BYE message is received. The function destroys the call handle and releases the memory allocated to operation context information. @code void app_r_bye(int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { if (status < 200) return; printf("call released\n"); /* release operation handle */ nua_handle_destroy(hmagic->handle); op->handle = NULL; /* release operation context information */ su_free(appl->home, hmagic); } /* app_r_bye */ @endcode The app_i_bye() function is called by the callback function when an incoming BYE message is received. The function destroys the call handle and releases the memory allocated to operation context information. @code void app_i_bye(int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { printf("call released\n"); /* release operation handle */ nua_handle_destroy(hmagic->handle); op->handle = NULL; /* release operation context information */ su_free(appl->home, hmagic); } /* app_i_bye */ @endcode @subsection nua_sendamessage Sending a message The following functions show an example of how a SIP MESSAGE is sent. The send_message() function sends the SIP MESSAGE. @code void send_message(void) { op_t *op; /* create operation context information */ op = su_zalloc(appl->home, sizeof(op_t)); if (op = NULL) { printf("cannot create operation context information\n"); return; } /* how we create destination_address? */ /* create operation handle */ op->handle = nua_handle(appl->nua, op, NUTAG_URL(destination_address), TAG_END()); if (op->handle == NULL) { printf("cannot create operation handle\n"); return; } /* send MESSAGE */ nua_message(op->handle, SIPTAG_CONTENT_TYPE_STR("text/plain"), SIPTAG_PAYLOAD_STR("Hello, world!"), /* other tags as needed ... */ TAG_END()); } /* send_message */ @endcode The app_r_message() function is called by the callback function when answer to the MESSAGE is received. @code void app_r_message(int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { printf("response to MESSAGE: %03d %s\n", status, phrase); } /* app_r_message */ @endcode @subsection nua_receivemessage Receiving a message The following function shows an example of how a SIP MESSAGE is received. The app_i_message() function is called by the callback function when a SIP MESSAGE is received. @code void app_i_message(int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { printf("received MESSAGE: %03d %s\n", status, phrase); printf("From: %s%s" URL_PRINT_FORMAT "\n", sip->sip_from->a_display ? sip->sip_from->a_display : "", sip->sip_from->a_display ?

Status and phrase values of the app_callback function indicate the success of the creation. Authorization of an incoming subscription (to the local presence server) can be handled in the callback function. @code void app_callback(nua_event_t event, int status, char const *phrase, nua_t *nua, application_t *app, nua_handle_t *nh, oper_t *op, sip_t const *sip, tagi_t tags[]) { nea_sub_t *subscriber = NULL; switch (event) { case nua_i_subscription: tl_gets(tags, NEATAG_SUB_REF(subscriber), TAG_END()); nua_authorize(nua_substate_active); default: break; } @endcode @subsection nua_shutting_down Shutdown The following functions show an example of how application terminates the NUA stack. The shutdown() function starts the termination. @code void shutdown(void) { nua_shutdown(appl->nua); } /* shutdown */ @endcode The app_r_shutdown() function is called by the callback function when NUA stack termination is either finished or failed. @code void app_r_shutdown(int status, char const *phrase, nua_t *nua, nua_magic_t *magic, nua_handle_t *nh, nua_hmagic_t *hmagic, sip_t const *sip, tagi_t tags[]) { printf("shutdown: %d %s\n", status, phrase); if (status < 200) { /* shutdown in progress -> return */ return; } /* end the event loop. su_root_run() will return */ su_root_break(magic->root); } /* app_r_shutdown */ @endcode */ /** @page nua_call_model NUA Call Model The NUA call follows a relatively simple state model presented below. The call model is used to present changes in call: when media starts to flow, when call is considered established, when call is terminated. In the figure below, a simplified state diagram for a SIP call is presented. After the call state has changes the application will receive an #nua_i_state event indicating the change. The states in NUA call model are represented by @e enum #nua_callstate, and the current value of state is included as the tag NUTAG_CALLSTATE() with the #nua_i_state event. The @RFC3264 SDP Offer/Answer negotiation status is also included in the #nua_i_state event. The negotiation status includes the local SDP (in SOATAG_LOCAL_SDP()) sent and flags indicating whether the local SDP was an offer or answer (NUTAG_OFFER_SENT(), NUTAG_ANSWER_SENT()). Likewise, the received remote SDP is included in tag SOATAG_REMOTE_SDP() and flags indicating whether the remote SDP was an offer or an answer in tags NUTAG_OFFER_RECV() or NUTAG_ANSWER_RECV(). SOATAG_ACTIVE_AUDIO() and SOATAG_ACTIVE_VIDEO() are informational tags used to indicate what is the status of these media. The #nua_i_state event is not sent, however, if the change is invoked by application calling API functions like nua_bye() and there is no change in SDP offer/answer status. @code +---------------+ +------| INIT |-----+ INVITE/- | +---------------+ | INVITE/100 V | +------------+ +------------+ +----| CALLING |--+ +---| RECEIVED |--+ | +------------+ | | +------------+ | | | | | | | | | 18X/- | | | -/18X | | V | | V | | +------------+ | | +------------+ | |<---| PROCEEDING | | | | EARLY |->| | +------------+ | | +------------+ | -/[3456]XX | | | | | | | | 2XX/- | 2XX/- | -/2XX | -/2XX | or | V | | V | | + - - - - - -+ | | +------------+ | CANCEL/200,487 | : COMPLETING :<-+ +-->| COMPLETE | | | + - - - - - -+ +------------+ | | | | | | | -/ACK ACK/- | | | | | | | | | | | | +---------------+ | | | +----->| READY |<----+ | | +---------------+ | | | | | | BYE/200 | | -/BYE | | | | | | | V | | | +--------------+ | | [3456]XX/ACK | | TERMINATING | | | | +--------------+ | | | | | | | | [23456]XX/- | | V V | | +---------------+ | +---------------->| TERMINATED |<--------------+ +---------------+ @endcode The labels "input/output" along each transition indicates SIP messages received from and sent to network, for instance, state transition "INVITE/100" occurs when a SIP @b INVITE request is received, and it is immediately returned a 100 (Trying) response.

# Previous state Input Output Next state Offer/ Answer Description
C1 init nua_invite() INVITE calling Generate offer Client application starts call be invoking nua_invite(). By default, stack runs the initial offer/answer step and sends @b INVITE request with the SDP offer.
C2 calling18X-proceeding (Save answer) Stack receives a 18X response (a provisional response between 101 and 199). It establishes an early dialog with server. If the provisional response contains an SDP answer, a session with early media is established. The caller can be listen to, for instance, ring tone or announcements about call progress using the early media session.
C3a calling2XX -completing Save answer Client receives a 2XX response (usually 200 OK) indicating that call has been accepted by the server. If there is an SDP session description included with response, it is stored. Unless the @ref NUTAG_AUTOACK() "auto-ack" mode is explicitly turned off by application the client does not stay in @b completing state, but proceeds immediately to next state transition.
C3b proceeding
C4 completing nua_ack() or
@ref NUTAG_AUTOACK() "auto-ack" 		ACKready Process answer Client sends an ACK request in this state transition. If the initial offer was sent with INVITE, the answer must have been received by this time, usually in the 2XX response. Client now completes the SDP offer-answer exchange and activates the media.
C5 completing nua_ack() or
@ref NUTAG_AUTOACK() "auto-ack" and
media error		 ACK
BYE		 terminating Process answer If there was a failure in SDP negotiation or other failure with media, the stack will automatically terminate the call. The BYE follows immediately after the ACK.
C6a calling 3XX 4XX
5XX 6XX		 ACK* terminated - Call is terminated when client receives a final error response (from 300 to 699) to its INVITE request. In this case, the underlying transaction engine takes care of sending ACK even when application-driven-ack mode is requested by application.
C6b proceeding
C7a calling nua_cancel() CANCEL calling - Client can ask server to cancel the call attempt while in @b calling or @b proceeding state. There is no direct call state transition caused by nua_cancel(). The call state changes when the server returns a response. After receiving a CANCEL request the server will usually return a 487 Request Terminated response and call is terminated as in previous item. However, there is a race condition and the server can respond with a succesful 2XX response before receiving CANCEL. In that case, the call is established as usual. It is up to application to terminate the call with nua_bye().
C7b proceeding proceeding
C8a calling nua_bye() CANCEL terminating* - The call cannot be terminated with BYE before the dialog is established with a non-100 preliminary response. So, instead of a @b BYE, stack sends a @b CANCEL request, and enters terminating state. However, there is a race condition and the server can respond with a succesful 2XX response before receiving CANCEL. If the server responds with a 2XX response, the nua will automatically send a BYE request asking server to terminate the call.
C8b proceeding nua_bye() BYE Even an early session can be terminated after entering @b proceeding state with nua_bye(). Stack sends a @b BYE request, and enters terminating state. Unlike @b CANCEL, @b BYE affects only one fork. However, there is a race condition and the server can respond with a succesful 2XX response before receiving BYE. If the server responds with a 2XX response, the nua will automatically send a BYE request asking server to terminate the call.
C9 completingnua_bye()ACK
BYE		terminating - If the stack is in @b completing state (it has already received 2XX response), it will have to @b ACK the final response, too.
C10 terminating* 2XX
to INVITE		 BYE terminating - There is a race condition between @b BYE and @b INVITE. The call may have been re-established with @b INVITE after @b BYE was processed. @b BYE is re-sent and call state transitions to normal terminating state.
C11 terminating* 3XX 4XX
5XX 6XX
to INVITE		 - terminated - The @b INVITE transaction is completed without a call being created. The call state transitions to terminated state.
C12 terminating 3XX 4XX
5XX 6XX
to BYE		 - terminated - Call is terminated when the final response to the BYE is received.

# Previous state Input Output Next state Offer/ Answer Description
S1 init INVITE 100 Trying received Save offer When a @b INVITE request for a new call is received, the server creates a fresh call handle for it, responds to the client with 100 Trying and enters in the @b received state by default. It saves the possible SDP offer included in @b INVITE and passes it to the application.
S2a received nua_respond() 18X early (Generate early answer) When server returns a preliminary response for the initial @b INVITE request, a early dialog is created. The server can also send an SDP answer with the preliminary answer and establish an early session, too. It can use the early session to send early media, e.g., ringing tone and announcements towards the client.
S2b init INVITE and @ref NUTAG_AUTOALERT() "auto-alert" 180 Ringing Save offer (and generate early answer) When @ref NUTAG_AUTOALERT() "auto-alert" option is enabled, stack sends 180 Ringing immediately after receiving INVITE and enters @b early state.
S3a received nua_respond() 2XX completed Generate answer When the server sends a 2XX response towards the client, it accepts the call. The @b INVITE transaction is now considered complete but unconfirmed at the server side. If the offer was sent in @b INVITE request, the answer should be included in the 2XX response.
S3b early
S3c init INVITE and @ref NUTAG_AUTOANSWER() "auto-answer" 200 OK Save offer and
generate answer		 When @ref NUTAG_AUTOANSWER() "auto-answer" option is enabled, stack send 200 OK immediately after receiving INVITE and enters @b completed state.
S4 completed ACK - ready - The ready state is entered at server side after receiving @b ACK request from client, indicating that the client have received server's 2XX response. The call is ready, the @b INVITE transaction is confirmed.
S5td> completed timeout BYE terminating - If the server does not receive an @b ACK request in timely fashion, it will terminate the call by sending a @b BYE request to client.
S6a received nua_respond() 3XX 4XX
5XX 6XX		 terminated - The server can reject the call by sending a 3XX, 4XX, 5XX, or 6XX response towards the client. The underlying transaction engine takes care of retransmitting the response when needed. It consumes the ACK response sent by the client, too.
S6b early
S7a received CANCEL 487 Request terminated terminated - The client can cancel the call attempt before it is completed with a @b CANCEL request. Server returns a 200 OK response to @b CANCEL and a 487 Request Terminated response to the @b INVITE transaction and the call is terminated.
S7b early
S8 early BYE 487 to INVITE
200 to BYE		 terminated - The client can terminate an early session with a @b BYE request, too. Like in the @b CANCEL case above, the server will terminate call immediately, return a 200 OK response to @b BYE and a 487 Request Terminated response to the @b INVITE transaction.
S9 completed BYE 200 to BYE terminated - The client can terminate a completed dialog with a @b BYE request. Server terminates call immediately, returns a 200 OK response to @b BYE and lets the underlying transaction engine to take care of consuming @b ACK.
@section nua_3pcc_call_model Third Party Call Control There is an alternative offer-answer model for third party call control (3pcc). The call setup involves a 3rd party, client C, which sends initial INVITE to server A without SDP. The call setup looks perfectly ordinary to server B, however. @code A C B | | | |<-------INVITE---------| | | | | | | | |------200 (offer)----->| | | |----INVITE (offer)---->| | | | | | | | |<-----200 (answer)-----| |<-----ACK (answer)-----| | | | | | |----------ACK--------->| | | | @endcode The modifications to the call model affect mainly offer-answer model. The detailed description of state transitions for 3pcc on the server side is as follows:
# Previous state Input Output Next state Offer/ Answer Description
S1' init INVITE 100 Trying received - There is no SDP to save.
S2b' init INVITE and @ref NUTAG_AUTOALERT() "auto-alert" 180 Ringing early - There is no SDP to save.
S3a' early nua_respond() 2XX completed Generate offer The offer is sent in 200 OK.
S3b' received
S3c' init INVITE and @ref NUTAG_AUTOANSWER() "auto-answer" 200 OK
S4' completed ACK - ready Save and process answer The answer is processed and media activated after receiving @b ACK.
S9b' completed ACK and O/A error BYE terminating Save and process answer If the offer/answer negotiation ends in error after the server receives answer in @b ACK request, the server will have to terminate call by sending a @b BYE request.
@section nua_terminate_call_model Model for Modifying and Terminating Call After the SIP session has been established, it can be further modified by @b INVITE transactions, initiated by either the original client or the original server. These so-called re-INVITE transactions can be used to upgrade session (add new media to it), put the session on hold or resume a held call. A session can be terminated with a @b BYE request at any time. If any in-dialog request (including re-INVITE) fails with certain response code, the session can be considered terminated, too. These response codes are documented with sip_response_terminates_dialog(). In some cases, the session should be terminated gracefully by sending a @b BYE request after the failed requests. @code +-------------------------------------------------------------+ | READY | +-------------------------------------------------------------+ | | | | | | | | (1) BYE/200 (2) nua_bye/BYE (4) graceful/BYE (5) fatal/- | | | | | V V | | +-----------------------------+ | | | TERMINATING | | | +-----------------------------+ | | | | | (3) [23456]XX/- | | | | V V V +-------------------------------------------------------------+ | TERMINATED | +-------------------------------------------------------------+ @endcode The detailed description of state transitions while call is terminated is as follows:
# Previous state Input Output Next state Description
T1 ready BYE 200 OK terminated When the @b BYE request is received, the recipient terminates the currently ongoing @b INVITE transaction, the session and its dialog usage (if there is another dialog usage active, e.g., a subscription creted by @b REFER.)
T2 ready nua_bye BYE terminating The application terminates the session by calling nua_bye(). All the call-related requests on the dialog are rejected while in terminating state with 487 No Such Call response.
T3 terminating 2XX 3XX 4XX 5XX 6XX - terminated The session is finally terminated when a final response to @b BYE is received. Note that nua stack does retry @b BYE requests.
T4 ready "graceful" response BYE terminating A call-related request (@b re-INVITE, @b UPDATE, @b INFO, @b PRACK, @b REFER) fails with a response code indicating that the client should gracefully terminate the call.
T5 ready "fatal" response - terminated A call-related request (@b re-INVITE, @b UPDATE, @b INFO, @b PRACK, @b REFER) fails with a response code indicating that the call has been terminated.

In SIP system this means that application can indicate to the remote end that it is engaged in other activity (another call, for instance) and does not wish to receive media from the remove end. The call hold is usully implemented using re-INVITE. Re-INVITE is an INVITE request sent on existing SIP session. Both original caller and callee can send re-INVITEs. The main use of re-INVITE is modifying sessions: adding media lines to the session, changing codecs on existing media, and, as you might expect, putting existing media on hold as well as resuming media from hold. A re-INVITE is sent by calling nua_invite() on handle with existing call. When putting call on hold, the application can include SOATAG_HOLD("audio") or SOATAG_HOLD("video") or SOATAG_HOLD("audio, video") or SOATAG_HOLD("*") as parameters to re-INVITE nua_invite(). (Note that last SOATAG_HOLD() in the tag list will override the SOATAG_HOLD() tags before it.) Another feature where nua tries to be helpful is autoanswer and auto-ACK on existing sessions: the re-INVITE is automatically responded with 200 OK and ACK is automatically sent. (If the application wants to respond and ACK by itself, it should explicitly set NUTAG_AUTOANSWER(0) and/or NUTAG_AUTOACK(0) in the handle; either include them in nua_invite() or nua_respond() parameters or call nua_set_hparams() explicitly. @code Alice Proxy Bob 0 nua_handle() | | | 1 | | | 2 nua_invite() -> |-----INVITE---->| | 3 nua_i_state <- | | | 4 | |-----INVITE---->| -> nua_i_invite 5 |<--100 Trying---| | -> nua_i_state 6 | | | 7 | | | 8 | | | 9 | |<--180 Ringing--| <- nua_respond(180) 10 nua_i_invite <- |<--180 Ringing--| | -> nua_i_state 11 nua_i_state <- | | | 12 | |<--200 OK-------| <- nua_respond(200) 13 nua_i_invite <- |<---200 OK------| | -> nua_i_state 14 nua_i_state <- | | | 15 nua_ack() -> |-----ACK------->| | 16 nua_i_state <- | |-----ACK------->| -> nua_i_ack 17 | | | -> nua_i_state 18 | | | 19 <<== Bi-Directional RTP Established ==>> 20 | | | 21 | | | 22 | |<--INVITE(hold)-| <- nua_invite(.. 21 | | | NUTAG_HOLD("*")..) 23 nua_i_invite <- |<-INVITE(hold)--| | -> nua_i_state 25 nua_i_state <- |----200 OK----->| | 26 | |----200 OK----->| -> nua_i_invite 28 | |<-----ACK-------| -> nua_i_state 29 nua_i_ack <- |<----ACK--------| | 24 | | | 30 <<== Uni-Directional RTP Established ==>> 24 | | | 31 | | | 32 | |<--INVITE-------| <- nua_invite(.. 21 | | | NUTAG_HOLD(NULL)..) 33 nua_i_invite <- |<--INVITE-------| | -> nua_i_state 35 nua_i_state <- |---200 OK------>| | 36 | |---200 OK------>| -> nua_i_invite 38 | |<----ACK--------| -> nua_i_state 39 nua_i_ack <- |<----ACK--------| | 40 nua_i_state <- | | | 19 <<== Bi-Directional RTP Established ==>> 42 | | | 43 nua_bye() -> |-----BYE------->| | 44 nua_i_state <- | |-----BYE------->| -> nua_i_bye 46 | |<----200 OK-----| -> nua_i_state 47 |<---200 OK------| | | | | @endcode @section nua_event_diagram_call_transfer Call Transfer This is the unattended call transfer case. 1st MSC showing Alice's end: @code Alice Bob Carol 0 | | | 1 nua_i_invite <- |<-----INVITE--------| | 2 nua_i_state <- | | | 2 | | | 3 nua_respond(180) -> |----180 Ringing---->| | 2 nua_i_state <- | | | 4 | | | 5 nua_respond(200) -> |------200 OK------->| | 6 nua_i_state <- | | | 8 | | | 7 nua_i_ack <- |<-------ACK---------| | 8 nua_i_state <- | | | 9 |<========RTP=======>| | 10 | | | 11 << Alice performs unattended transfer >> | 12 | | | 13 | | | 14 nua_refer() -> |---REFER("r: C")--->| | 15 | | | 16 nua_r_refer <- |<---202 Accepted----| | 17 | | | 18 nua_i_notify <- |<-----NOTIFY--------| | 19 | | | 20 |------200 OK------->| | 21 | |---INVITE("b: A")-->| 23 | | | 22 nua_bye() -> |-------BYE--------->| | 23 | | | 24 nua_r_bye <- |<----200 OK---------| | 25 nua_i_state <- | No RTP Session | | 28 | |<----180 Ringing----| 26 nua_i_notify <- |<- - -NOTIFY - - - -| | 27 | | | 20 |- - - 200 OK- - - ->| | 29 | | | 30 | |<------200 OK-------| 31 | | | 32 | |---------ACK------->| 33 | | RTP | 34 | |<==================>| 35 | | | 36 |<-----NOTIFY--------| | 37 | | | 38 |------200 OK------->| | | | | @endcode 2nd MSC showing Bobs's end: @code Alice Bob (nh1) Bob (nh2) Carol 0 | | | | 1 |<-----INVITE--------| | | 2 | | | | 3 |---180 Ringing----->| | | 4 | | | | 5 |------200 OK------->| | | 6 | | | | 7 |<-------ACK---------| | | 8 | RTP | | | 9 |<==================>| | | 10 | | | | 11<< Alice performs unattended transfer >> | | 12 | | | | 13 | Refer-To:C F5| | | 14 |-REFER------------->| -> nua_i_refer | | 15 | | | | 16 |<-202 Accepted------| | | 17 | | | | 18 |<-----NOTIFY--------| | | 19 | | | | 20 |------200 OK------->| -> nua_r_notify | | 21 | | | | 22 |-------BYE--------->| -> nua_i_bye | | 23 | | -> nua_i_state | | 24 |<----200 OK---------| nua_handle() -> | | 25 | No RTP Session | nua_invite() -> | | 26 | | |--INVITE("b: A")--->| 27 | | | | 28 | | nua_i_invite <- |<--180 Ringing------| 29 | | nua_i_state <- | | 30 | | nua_i_invite <- |<----200 OK---------| 31 | | nua_i_state <- | | 32 | | nua_ack -> |-------ACK--------->| 33 | | | | 34 | | |<=======RTP========>| 35 | | | | 36 |<-----NOTIFY--------| | | 37 | | 38 |------200 OK------->| -> nua_r_notify 39 | | <- nua_handle_destroy | | @endcode Bob includes nh1 in nua_invite()/25 as NUTAG_NOTIFY_REFER() parameter.

After the request is * complete, it is removed from the queue and destroyed by the default. The * exception is the client requests bound to a dialog usage: they are saved * and re-used when the dialog usage is refreshed (and sometimes when the * usage is terminated). * * The client request is subclassed and its behaviour modified using virtual * function table in #nua_client_methods_t. * * The first three methods (crm_template(), crm_init(), crm_send()) are * called when the request is sent first time. * * The crm_template() is called if a template request message is needed (for * example, in case of unregister, unsubscribe and unpublish, the template * message is taken from the request establishing the usage). * * The crm_init() is called when the template message and dialog leg has * been created and populated by the tags procided by the application. Its * parameters msg and sip are pointer to the template request message that * is saved in the nua_client_request::cr_msg field. * * The crm_send() is called with a copy of the template message that has * been populated with all the fields included in the request, including * @CSeq and @MaxForwards. The crm_send() function, such as * nua_publish_client_request(), usually calls nua_base_client_trequest() that * then creates the nta-level transaction. * * The response to the request is processed by crm_check_restart(), which * modifies and restarts the request when needed (e.g., when negotiating * expiration time). After the request has been suitably modified, e.g., the * expiration time has been increased, the restart function calls * nua_client_restart(), which restarts the request and relays the * intermediate response to the application with nua_client_restart() and * crm_report(). * * The final responses are processed by crm_recv() and and preliminary ones * by crm_preliminary(). All virtual functions should call * nua_base_client_response() beside method-specific processing. * * The nua_base_client_response() relays the response to the application with * nua_client_restart() and crm_report(). * * @par Terminating Dialog Usages and Dialogs * * The response is marked as terminating with nua_client_set_terminating(). * When a terminating request completes the dialog usage is removed and the * dialog is destroyed (unless there is an another active usage). */ static void nua_client_request_destroy(nua_client_request_t *cr);

It will obtain the schema, IP address * for the host and port number for the Contact URI from the transport * socket. The diplay name is taken from NUTAG_M_DISPLAY(), URL username * part is taken from NUTAG_M_USERNAME(), URI parameters from * NUTAG_M_PARAMS(), and Contact header parameters from NUTAG_M_FEATURES(). * If NUTAG_CALLEE_CAPS(1) is specified, additional Contact header * parameters are generated based on SDP capabilities and SIP @Allow header. * * Note that @b nua may append a identifier of its own to the @Contact URI * username. Such nua-generated identifier trailer always starts with "=" * (equal sign), rest of the nua-generated identifier may contain any * url-unreserved characters except "=". * * Likewise, nua may add transport parameters (such as "transport=tcp" or * "maddr") to the @Contact URI. It can add addtional header parameters, like * "+sip.instance" or "reg-id", too. * * For instance, if application uses tags like * @code * nua_register(nh, * NUTAG_M_DISPLAY("1"), * NUTAG_M_USERNAME("line-1"), * NUTAG_M_PARAMS("user=phone"), * NUTAG_M_FEATURES("audio"), * NUTAG_CALLEE_CAPS(0), * TAG_END()) * @endcode * @b nua can generate a Contact header like * @code * Contact: 1 * ;audio;reg-id=1 * ;+sip.instance=urn:uuid:97701ad9-39df-1229-1083-dbc0a85f029c * @endcode * * The incoming request from the proxy should contain the registered contact * URI as the request URI. The application can use the username prefix set * by NUTAG_M_USERNAME() and the non-transport parameters of the request URI * set by NUTAG_M_PARAMS() when determining to which registration the * incoming request belongs. * * For example, a request line correspoding to the @Contact in above example * may look like: * @code * INVITE sip:line-1=SSQAIbjv@192.168.1.200;user=phone SIP/2.0 * @endcode * * @sa NUTAG_M_DISPLAY(), NUTAG_M_USERNAME(), NUTAG_M_PARAMS(), * NUTAG_M_FEATURES(), NUTAG_CALLEE_CAPS(). * * @par NAT, Firewall and Outbound Support * * Normally, @b nua will start start a protocol engine for outbound * connections used for NAT and firewall traversal and connectivity checks * when registering. * * @note If the application provides @b nua with a * @Contact header of its own (or includes a SIPTAG_CONTACT(NULL) tag in * nua_register() tags), the outbound protocol engine is not started. It is * assumed that the application knows better what it is doing when it sets * the @Contact, or it is using experimental CPL upload as specified in * * draft-lennox-sip-reg-payload-01.txt. * * First, outbound engine will probe for NATs in between UA and registrar. * It will send a REGISTER request as usual. Upon receiving the response it * checks for the presence of "received" and "rport" parameters in the Via * header returned by registrar. The presence of NAT is determined from the * "received" parameter in a Via header. When a REGISTER request was sent, * the stack inserted the actual source IP address in the Via header: if * that is different from the source IP address seen by the registrar, the * registrar inserts the source IP address it sees into the "received" * parameter. * * Please note that an ALG (application-level gateway) modifying the Via * headers in outbound requests and again in incoming responses will make * the above-described NAT check to fail. * * The response to the initial REGISTER should also include option tags * indicating whether registrar supports various SIP extension options: @e * outbound, @e pref, @e path, @e gruu. * * Basically, @e outbound means that instead of registering its contact URI * with a particular address-of-record URI, the user-agent registers a * transport-level connection. Such a connection is identified on the * Contact header field with an instance identifier, application-provided * @ref NUTAG_INSTANCE() "unique string" identifying the user-agent instance * and a stack-generated numeric index identifying the transport-level * connection. * * If the @e outbound extension is supported, NUTAG_OUTBOUND() contains * option string "outbound" and the application has provided an instance * identifer to the stack with NUTAG_INSTANCE(), the nua_register() will try * to use outbound. * * If @e outbound is not supported, nua_register() has to generate a URI * that can be used to reach it from outside. It will check for public * transport addresses detected by underlying stack with, e.g., STUN, UPnP * or SOCKS. If there are public addresses, nua_register() will use them. If * there is no public address, it will try to generate a Contact URI from * the "received" and "rport" parameters found in the Via header of the * response message. * * @todo Actually generate public addresses. * * You can disable this kind of NAT traversal by setting "no-natify" into * NUTAG_OUTBOUND() options string. * * @par GRUU and Service-Route * * After a successful response to the REGISTER request has been received, * nua_register() will update the information about the registration based * on it. If there is a "gruu" parameter included in the response, * nua_register() will save it and use the gruu URI in the Contact header * fields of dialog-establishing messages, such as INVITE or SUBSCRIBE. * Also, if the registrar has included a Service-Route header in the * response, and the service route feature has not been disabled using * NUTAG_SERVICE_ROUTE_ENABLE(), the route URIs from the Service-Route * header will be used for initial non-REGISTER requests. * * The #nua_r_register message will include the contact header and route * used in with the registration. * * @par Registration Keep-Alive * * After the registration has successfully completed the nua_register() will * validate the registration and initiate the keepalive mechanism, too. The * user-agent validates the registration by sending a OPTIONS requests to * itself. If there is an error, nua_register() will indicate that to the * application using #nua_i_outbound event, and start unregistration * procedure (unless that has been explicitly disabled). * * You can disable validation by inserting "no-validate" into * NUTAG_OUTBOUND() string. * * The keepalive mechanism depends on the network features detected earlier. * If @a outbound extension is used, the STUN keepalives will be used. * Otherwise, NUA stack will repeatedly send OPTIONS requests to itself. In * order to save bandwidth, it will include Max-Forwards: 0 in the * keep-alive requests, however. The keepalive interval is determined by * NUTAG_KEEPALIVE() parameter. If the interval is 0, no keepalive messages * is sent. * * You can disable keepalive OPTIONS by inserting "no-options-keepalive" * into NUTAG_OUTBOUND() string. Currently there are no other keepalive * mechanisms available. * * The value of NUTAG_KEEPALIVE_STREAM(), if specified, is used to indicate * the desired transport-layer keepalive interval for stream-based * transports like TLS and TCP. * * As alternative to OPTIONS/STUN keepalives, the client can propose * a more frequent registration refresh interval with * NUTAG_M_FEATURES() (e.g. NUTAG_M_FEATURES("expires=120") given as * parameter to nua_register()). * * @sa #nua_r_register, nua_unregister(), #nua_r_unregister, * #nua_i_register, * @RFC3261 section 10, * @Expires, @Contact, @CallID, @CSeq, * @Path, @RFC3327, @ServiceRoute, @RFC3608, @RFC3680, * NUTAG_REGISTRAR(), NUTAG_INSTANCE(), NUTAG_OUTBOUND(), * NUTAG_KEEPALIVE(), NUTAG_KEEPALIVE_STREAM(), * SIPTAG_CONTACT(), SIPTAG_CONTACT_STR(), NUTAG_M_USERNAME(), * NUTAG_M_DISPLAY(), NUTAG_M_PARAMS(), NUTAG_M_FEATURES(), */ /** @NUA_EVENT nua_r_register * * Response to an outgoing REGISTER. * * The REGISTER may be sent explicitly by nua_register() or implicitly by * NUA state machines. * * When REGISTER request has been restarted the @a status may be 100 even * while the real response status returned is different. * * @param status response status code * (if the request is retried, @a status is 100, the @a * sip->sip_status->st_status contain the real status code * from the response message, e.g., 302, 401, or 407) * @param phrase a short textual description of @a status code * @param nh operation handle associated with the registration * @param hmagic application context associated with the registration * @param sip response message to REGISTER request or NULL upon an error * (status code is in @a status and * descriptive message in @a phrase parameters) * @param tags empty * * @sa nua_register(), nua_unregister(), #nua_r_unregister, * @Contact, @CallID, @CSeq, @RFC3261 section 10, * @Path, @RFC3327, @ServiceRoute, @RFC3608, @RFC3680 * * @END_NUA_EVENT */ /**@fn void nua_unregister(nua_handle_t *nh, tag_type_t tag, tag_value_t value, ...); * Unregister. * * Send a REGISTER request with expiration time 0.

When the INVITE message (or any other SIP message) is created, * the tagged values saved with nua_handle() are used first, next the tagged * values given with the operation (nua_invite()) are added. * * @par * When multiple tags for the same header are specified, the behaviour * depends on the header type. If only a single header field can be included * in a SIP message, the latest non-NULL value is used, e.g., @Subject. * However, if the SIP header can consist of multiple lines or header fields * separated by comma, e.g., @Accept, all the tagged * values are concatenated. * * @par * However, if a tag value is #SIP_NONE (-1 casted as a void pointer), the * values from previous tags are ignored. * * @par * Next, values previously set with nua_set_params() or nua_set_hparams() * are used: @Allow, @Supported, @Organization, and @UserAgent headers are * added to the request if they are not already set. * * @par * Now, the target URI for the request needs to be determined. * * @par * For initial INVITE requests, values from tags are used. If NUTAG_URL() is * given, it is used as target URI. Otherwise, if SIPTAG_TO() is given, it * is used as target URI. If neither is given, the complete request line * already specified using SIPTAG_REQUEST() or SIPTAG_REQUEST_STR() is used. * If none of the tags above are given, an internal error is returned to the * application. At this point, the target URI is stored in the request line, * together with method name ("INVITE") and protocol version ("SIP/2.0"). * The initial dialog information is also created: @CallID, @CSeq headers * are generated, if they do not exist, and an unique tag is added to @From * header. * * @par * For the initial INVITE requests, the @Route headers specified by * SIPTAG_ROUTE()/SIPTAG_ROUTER_STR() tags in nua_handle() and nua_invite() * calls are inserted to the request. Next the initial route set specified * by NUTAG_INITIAL_ROUTE()/NUTAG_INITIAL_ROUTE_STR() tags is prepended to * the route. Finally (unless NUTAG_SERVICE_ROUTE_ENABLE(0) is used) the * @ServiceRoute set received from the registrar is also appended to the * route set of the initial request message. * * @par * Next, the stack generates a @Contact header for the request (Unless the * application already gave a @Contact header or it does not want to use * @Contact and indicates that by including SIPTAG_CONTACT(NULL) or * SIPTAG_CONTACT(SIP_NONE) in the tagged parameters.) If the application * has a registration active, the @Contact header used with registration is * used. Otherwise, the @Contact header is generated from the local IP * address and port number, taking also the values from NUTAG_M_DISPLAY(), * NUTAG_M_FEATURES(), NUTAG_M_PARAMS(), and NUTAG_M_USERNAME(). * * @par * For in-dialog INVITE (re-INVITE), the request URI is taken from the * @Contact header received from the remote party during the dialog * establishment. Also, the @CallID and @CSeq headers and @From and @To tags * are generated based on the dialog information and added to the request. * If the dialog has a route (set by @RecordRoute headers), it is added to * the request, too. * * @par * @MaxForwards header (with default value set by NTATAG_MAX_FORWARDS()) is * also added now, if it does not exist. * * @par * The INVITE request message created by nua_invite() operation is saved as * a template for automatic re-INVITE requests sent by the session timer * ("timer") feature (see NUTAG_SESSION_TIMER() for more details). Please * note that the template message is not used when ACK, PRACK, UPDATE or * INFO requests are created (however, these requests will include * dialog-specific headers like @To, @From, and @CallID as well as * preference headers @Allow, @Supported, @UserAgent, @Organization). * * @par Tags Related to SIP Headers and Request-URI * NUTAG_URL(), SIPTAG_REQUEST(), SIPTAG_REQUEST_STR() \n * NUTAG_INITIAL_ROUTE(), NUTAG_INITIAL_ROUTE_STR(), * SIPTAG_ROUTE(), SIPTAG_ROUTE_STR(), * NUTAG_SERVICE_ROUTE_ENABLE() \n * SIPTAG_MAX_FORWARDS(), SIPTAG_MAX_FORWARDS_STR() \n * SIPTAG_PROXY_REQUIRE(), SIPTAG_PROXY_REQUIRE_STR() \n * SIPTAG_FROM(), SIPTAG_FROM_STR() \n * SIPTAG_TO(), SIPTAG_TO_STR() \n * SIPTAG_CALL_ID(), SIPTAG_CALL_ID_STR() \n * SIPTAG_CSEQ(), SIPTAG_CSEQ_STR() * (note that @CSeq value is incremented if request gets retried)\n * SIPTAG_CONTACT(), SIPTAG_CONTACT_STR() \n * SIPTAG_REQUEST_DISPOSITION(), SIPTAG_REQUEST_DISPOSITION_STR() \n * SIPTAG_ACCEPT_CONTACT(), SIPTAG_ACCEPT_CONTACT_STR() \n * SIPTAG_REJECT_CONTACT(), SIPTAG_REJECT_CONTACT_STR() \n * SIPTAG_EXPIRES(), SIPTAG_EXPIRES_STR() \n * SIPTAG_DATE(), SIPTAG_DATE_STR() \n * SIPTAG_TIMESTAMP(), SIPTAG_TIMESTAMP_STR() \n * SIPTAG_SUBJECT(), SIPTAG_SUBJECT_STR() \n * SIPTAG_PRIORITY(), SIPTAG_PRIORITY_STR() \n * SIPTAG_CALL_INFO(), SIPTAG_CALL_INFO_STR() \n * SIPTAG_ORGANIZATION(), SIPTAG_ORGANIZATION_STR() \n * NUTAG_USER_AGENT(), SIPTAG_USER_AGENT() and SIPTAG_USER_AGENT_STR() \n * SIPTAG_IN_REPLY_TO(), SIPTAG_IN_REPLY_TO_STR() \n * SIPTAG_ACCEPT(), SIPTAG_ACCEPT_STR() \n * SIPTAG_ACCEPT_ENCODING(), SIPTAG_ACCEPT_ENCODING_STR() \n * SIPTAG_ACCEPT_LANGUAGE(), SIPTAG_ACCEPT_LANGUAGE_STR() \n * NUTAG_ALLOW(), SIPTAG_ALLOW(), and SIPTAG_ALLOW_STR() \n * NUTAG_EARLY_MEDIA(), SIPTAG_REQUIRE(), and SIPTAG_REQUIRE_STR() \n * NUTAG_SUPPORTED(), SIPTAG_SUPPORTED(), and SIPTAG_SUPPORTED_STR() \n * SIPTAG_ALLOW_EVENTS(), SIPTAG_ALLOW_EVENTS_STR() \n * SIPTAG_PROXY_AUTHORIZATION(), SIPTAG_PROXY_AUTHORIZATION_STR() \n * SIPTAG_AUTHORIZATION(), SIPTAG_AUTHORIZATION_STR() \n * SIPTAG_REFERRED_BY(), SIPTAG_REFERRED_BY_STR() \n * SIPTAG_REPLACES(), SIPTAG_REPLACES_STR() \n * NUTAG_SESSION_TIMER(), NUTAG_SESSION_REFRESHER(), * SIPTAG_SESSION_EXPIRES(), SIPTAG_SESSION_EXPIRES_STR() \n * NUTAG_MIN_SE(), SIPTAG_MIN_SE(), SIPTAG_MIN_SE_STR() \n * SIPTAG_SECURITY_CLIENT(), SIPTAG_SECURITY_CLIENT_STR() \n * SIPTAG_SECURITY_VERIFY(), SIPTAG_SECURITY_VERIFY_STR() \n * SIPTAG_PRIVACY(), SIPTAG_PRIVACY_STR() \n * SIPTAG_MIME_VERSION(), SIPTAG_MIME_VERSION_STR() \n * SIPTAG_CONTENT_TYPE(), SIPTAG_CONTENT_TYPE_STR() \n * SIPTAG_CONTENT_ENCODING(), SIPTAG_CONTENT_ENCODING_STR() \n * SIPTAG_CONTENT_LANGUAGE(), SIPTAG_CONTENT_LANGUAGE_STR() \n * SIPTAG_CONTENT_DISPOSITION(), SIPTAG_CONTENT_DISPOSITION_STR() \n * SIPTAG_HEADER(), SIPTAG_HEADER_STR() \n * SIPTAG_PAYLOAD(), SIPTAG_PAYLOAD_STR() \n * * @par SDP Handling * By default the nua_invite() uses an @ref soa_session_t "SOA media * session" object to take care of the Offer/Answer exchange.

See the @ref nua_call_model * for the detailed explanation of various options in call processing at * server end. * * The @b INVITE request takes care of session setup using SDP Offer-Answer * negotiation as specified in @RFC3264 (updated in @RFC3262 section 5, * @RFC3311, and @RFC3312). The Offer-Answer can be taken care by * application (if NUTAG_MEDIA_ENABLE(0) parameter has been set) or by the * built-in SDP Offer/Answer engine @soa (by default and when * NUTAG_MEDIA_ENABLE(1) parameter has been set). When @soa is enabled, it * will take care of parsing the SDP, negotiating the media and codecs, and * including the SDP in the SIP message bodies as required by the * Offer-Answer model. * * When @soa is enabled, the SDP in the incoming INVITE is parsed and feed * to a #soa_session_t object. The #nua_i_state event sent to the * application immediately after #nua_i_invite will contain the parsing * results in SOATAG_REMOTE_SDP() and SOATAG_REMOTE_SDP_STR() tags. * * Note that currently the parser within @nua does not handle MIME * multipart. The SDP Offer/Answer engine can get confused if the SDP offer * is included in a MIME multipart, therefore such an @b INVITE is rejected * with 415 Unsupported Media Type error response: the client is * expected to retry the INVITE without MIME multipart content. * * If the call is to be accepted, the application should include the SDP in * the 2XX response. If @soa is not disabled with NUTAG_MEDIA_ENABLE(0), the * SDP should be included in the SOATAG_USER_SDP() or SOATAG_USER_SDP_STR() * parameter given to nua_respond(). If it is disabled, the SDP should be * included in the response message using SIPTAG_PAYLOAD() or * SIPTAG_PAYLOAD_STR(). Also, the @ContentType should be set using * SIPTAG_CONTENT_TYPE() or SIPTAG_CONTENT_TYPE_STR(). * * @par Preliminary Responses and 100rel * * Call progress can be signaled with preliminary responses (with status * code in the range 101..199). It is possible to conclude the SDP * Offer-Answer negotiation using preliminary responses, too. If * NUTAG_EARLY_ANSWER(1), SOATAG_USER_SDP() or SOATAG_USER_SDP_STR() * parameter is included with in a preliminary nua_response(), the SDP * answer is generated and sent with the preliminary responses, too. * * The preliminary responses are sent reliably if feature tag "100rel" is * included in the @Require header of the response or if * NUTAG_EARLY_MEDIA(1) parameter has been given. The reliably delivery of * preliminary responses mean that a sequence number is included in the * @RSeq header in the response message and the response message is resent * until the client responds with a @b PRACK request with matching sequence * number in @RAck header. * * Note that only the "183" response is sent reliably if the * NUTAG_ONLY183_100REL(1) parameter has been given. The reliable * preliminary responses are acknowledged with @b PRACK request sent by the * client. * * Note if the SDP offer-answer is completed with the reliable preliminary * responses, the is no need to include SDP in 200 OK response (or other 2XX * response). However, it the tag NUTAG_INCLUDE_EXTRA_SDP(1) is included * with nua_respond(), a copy of the SDP answer generated earlier by @soa is * included as the message body. * * @sa nua_respond(), @ref nua_uas_call_model, #nua_i_state, * NUTAG_MEDIA_ENABLE(), SOATAG_USER_SDP(), SOATAG_USER_SDP_STR(), * @RFC3262, NUTAG_EARLY_ANSWER(), NUTAG_EARLY_MEDIA(), * NUTAG_ONLY183_100REL(), * NUTAG_INCLUDE_EXTRA_SDP(), * #nua_i_prack, #nua_i_update, nua_update(), * nua_invite(), #nua_r_invite * * @par * @par Third Party Call Control * * When so called 2rd party call control is used, the initial @b INVITE may * not contain SDP offer.

The parser also implements support for IPv6 addresses as per @RFC3266. The @RFC4566 should be supported, but we have not checked since draft-eitf-mmusic-sdp-new-17 or so. @CONTACT Pekka Pessi @STATUS @SofiaSIP Core library @LICENSE LGPL Contributor(s): - Pekka Pessi - Jari Selin @section sdp_parser SDP Parser SDP parser parses an SDP message and converts it to internally used SDP structure #sdp_session_t. Typically, the SDP parser is used as follows: @code sdp_parser_t *parser = sdp_parse(home, message, len, 0); if (!sdp_session(parser)) { show(sdp_parsing_error(parser)); } else { sdp_session_t *sdp = sdp_session(parser); @endcode Act upon session description, then free the parser: @code } sdp_parser_free(parser); @endcode There are various flags indicating what kind of SDP variants the sdp_parse() accepts. The sanity check run after parsing can be disabled by including flag #sdp_f_insane. The parser can be used to parse syntactically vague configuration files when using flag #sdp_f_config.

Typically, the SDP printer is used as follows: @code char buffer[512]; sdp_printer_t *printer = sdp_print(home, session, buffer, sizeof(buffer), 0); if (sdp_message(printer)) { char const *msg = sdp_message(printer); size_t msgsize = sdp_message_size(printer); @endcode At this point, application can use the SDP message contents, e.g., it can send them to network, and then free the message: @code } else { show_critical_error(sdp_printing_error(printer)); } sdp_printer_free(printer); @endcode @section sdp_example Example Examples on using SDP parser can be found from test_sdp.c and soa.c. Here is an simple example, which decodes an SDP text in @a original, increments the version number in the origin line, and encodes the SDP description again to @a buf. @code size_t increment_sdp_version(char buf[], size_t bsize, char const *original, size_t osize) { su_home_t home[1] = { SU_HOME_INIT(home) }; sdp_parser_t *parser = sdp_parse(home, original, osize, 0); sdp_printer_t *printer; size_t retval = 0; if (sdp_session(parser)) { sdp_session_t *sdp = sdp_session(parser); sdp->sdp_origin->o_version++; printer = sdp_print(home, sdp, buf, bsize, 0); if (sdp_message(printer)) { retval = sdp_message_size(printer); } else { fprintf(stderr, "increment_sdp_version: %s\n", sdp_printing_error(printer)); } sdp_printer_free(printer); } else { fprintf(stderr, "increment_sdp_version: %s\n", sdp_parsing_error(parser)); } sdp_parser_free(parser); su_home_deinit(home); return retval; } @endcode */ sofia-sip-1.12.11+20110422.1/libsofia-sip-ua/sdp/sdp_parse.c000066400000000000000000001427001223300710500224700ustar00rootroot00000000000000/* * This file is part of the Sofia-SIP package * * Copyright (C) 2005 Nokia Corporation. * * Contact: Pekka Pessi * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public License * as published by the Free Software Foundation; either version 2.1 of * the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, but * WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

In the text below, we use "Example" header as our example with following ABNF: sip-example = "Example" COLON 1*DIGIT IF YOUR HEADER IS A STANDARD ONE -------------------------------- * In , add: - Add typedef to the header structure. You should add a typedef line like this: typedef struct sip_example_s sip_example_t; Note that the typedefs are documented together with the implementation in the .c file. - Add the actual header structure: The header structure would look like below. The first field MUST be a sip_common_t structure, second field MUST be a pointer to next header with same name. As a convention, if there can be only one header field of this kind, the type of the "next" pointer is sip_error_t. The fields representing the header value are located after the mandatory fields, usually in the order they are present in the header contents. In this case, the Example header consist of a 32-bit integer: /**@ingroup sip_example * @brief Structure for Example header. */ struct sip_example_s { sip_common_t ex_common[1]; /**< Common fragment info. */ sip_error_t *ex_next; /**< Link to next (dummy). */ unsigned long ex_value; /**< Value of example. */ }; * Add entry to sip_extra_headers.txt: - In this case: example @NEW_2_0 /* Example header */ - The first is the base C name used for functions and types related to the type. The AWK script msg_parser.awk automatically creates the default prototypes and tags for the newly created header. It will complain about mismatches between header name and the base name. - If the entry is before #### DEFAULT HEADER LIST ENDS HERE #### the new header is added to the default parser - If after, the new header is added only to the extended parser. - The extended parser will be used after call to sip_update_default_mclass(NULL) * Write parsing tests for your new headers in torture_sip.c: Add all relevant parsing/processing cases you can think of at the end of function sip_header_test() or add a testing function of your own. * Add implementation in a suitable ".c" file - For an simple example, see implementation of Date header in sip_basic.c - Add a documentation group with @defgroup - Document the typedef - Add header class structure - Add parsing and printing functions: + sip_example_d(), sip_example_e() - Add functions used when copying the header structure: + sip_example_dup_xtra(), sip_example_dup_one() * If you added a .c file, add to the Makefile.am - remember to run autogen.sh unless you have given --enable-maintainer-mode to configure script * Run "make check" after you are ready * Run "make check" after you are ready. Really. IF YOUR HEADERS ARE COMPLETELY NON-STANDARD ------------------------------------------- * Add a separate library package for them - There is an example package sofia-sip-2543.tar.gz, available from sofia-sip.sourceforge.net See the extension package for 1) - Create a header template for your header just like sofia-sip/rfc2543.h.in (found in package), e.g, sip_example.h.in: ---8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--- /**@file sip_example.h.in * * Template for . */ #ifndef SIP_EXAMPLE_H /** Defined when has been included. */ #define SIP_EXAMPLE_H /**@file sip_example.h * * @brief Example header. * * #AUTO# * * @author Pekka Pessi . * * @date Created: Fri May 27 18:40:38 EEST 2005 ppessi */ #ifndef SIP_H #include #endif #ifndef SIP_HEADER_H #include #endif /**@ingroup sip_example * @brief Structure for @b Example header. */ struct sip_example_s { sip_common_t ex_common[1]; /**< Common fragment info */ sip_error_t *ex_next; /**< Link to next (dummy). */ uint32_t ex_value; /**< Value of Example */ }; typedef struct sip_example_s sip_example_t; struct sip_example_dummy_structure { /* === Headers start here */ sip_example_t *sip_example; /**< Example */ /* === Headers end here */ }; #endif /** !defined(SIP_EXAMPLE_H) */ --->8---->8---->8---->8---->8---->8---->8---->8---->8---->8---->8---->8--- sofia-sip-1.12.11+20110422.1/libsofia-sip-ua/sip/ChangeLog000066400000000000000000000034731223300710500221260ustar00rootroot000000000000002006-01-25 Kai Vehmanen * Doxyfile (INPUT): Missing sip_dll.c broke refdoc build.

In addition to the * header structure, there is defined a @em header @em class structure and * some standard functions for each header in the include file @b * . For header @c X, there are types, functions, * macros and header class declared in and * . See @ref sip_header_x for detailed description * of these header-specific boilerplate declarations. * * In addition to this interface, the @ref sip_parser "SIP parser documentation" * contains description of the functionality required when a parser is * extended by a new header. It is possible to add new headers to the SIP * parser or extend the definition of existing ones. * * @section sip_parser_intro Parsing SIP Messages * * Sofia SIP parser follows @em recursive-descent principle. In other words, * it is a program that descends the SIP syntax tree top-down recursively. * (All syntax trees have root at top and they grow downwards.) * * In the case of SIP such a parser is very efficient. The parser can choose * between different forms based on each token, as SIP syntax is carefully * designed so that it requires only minimal scan-ahead. It is also easy to * extend a recursive-descent parser via a standard API, unlike, for * instance, a LALR parser generated by @em Bison. * * The abstract message module @b msg contains a high-level parser engine * that drives the parsing process and invokes the SIP parser for each * header. As there are no framing between SIP messages, the parser * considers any received data, be it a UDP datagram or a TCP stream, as a * @em message @em stream, which may consist of one or more SIP messages. * The parser works by first separating stream into fragments, then building * a complete message based on parsing result. After a message is completed, * it can be given to the message stream customer (typically a protocol * state machine). The parser continues processing the stream and feeding * the messages to protocol engine until the end of the stream is reached. * * For each message, the parser starts by separating the first fragment, * which is either a request or status line. After the first line has been * processed, the parser engine continues by separating the headers * one-by-one from the message. After the parser encounters an empty line * separating the headers and the message body (payload), it invokes a * function parsing the separator and payload fragment(s). When the message * is complete, the parser can hand the message over to the protocol engine. * Then it is ready to start again with first fragment of the next message. * * @image html sip-parser.gif Separating byte stream to messages * @image latex sip-parser.eps Separating byte stream to messages * * When the parsing process has completed, the request or status line, each * header, separator and the payload are all in their own fragment * structure. The fragments form a dual-linked list known as @e fragment @e * chain as shown in the above figure. The buffers for the message, the * fragment chain, and a whole other stuff is held by the generic message * type, #msg_t, defined in . The internal structure of #msg_t is * known only within @b msg module and it is hidden from other modules. * * The abstract message module @b msg also drives the reverse process, * invoking the encoding method of each fragment so that the whole outgoing * SIP message is encoded properly. * * @section sip_header_struct SIP Header as a C struct * * Just separating headers from each other and from the message body is not * usually enough. When a header contains structured data, the header * contents should be converted to a form that is convenient to use from C * programs. For that purpose, the message parser needs a special function * for each individual header. The header-specific parsing function divides * the contents of the header into semantically meaningful segments and * stores the result in a header-specific structure. * * The parser passes the fragment contents to a parsing function immediately * after it has separated a fragment from the message. The parsing function * is defined by the @e header @e class. The header class is either * determined by the fragment position (first line, separator line or * payload), or it is found from the hash table using the header name as * key. There is also a special header class for @e unknown headers, headers * with a name that is not regocnized by the parser. * * For instance, the @From header has following syntax: * * @code * from = ("From" | "f") ":" * ( name-addr | addr-spec ) *( ";" addr-params ) * name-addr = [ display-name ] "<" addr-spec ">" * addr-spec = SIP-URL | URI * display-name = *token | quoted-string * addr-params = *( tag-param | generic-param ) * tag-param = "tag" "=" ( token | quoted-string ) * @endcode * * When a @From header is parsed, the header parser function sip_from_d() * separates the @e display-name, @e addr-spec and each parameter in the @e * addr-params list. The parsing result is assigned to a #sip_from_t * structure, which is defined as follows: * * @code * typedef struct sip_addr_s { * sip_common_t a_common[1]; * sip_unknown_t *a_next; * char const *a_display; * url_t a_url[1]; * sip_param_t const *a_params; * char const *a_tag; * } sip_from_t; * @endcode * * The string containing the @e display-name is put into the @c a_display * field, the URL contents can be found in the @c a_url field, and the list * of @e addr-params parameters is put in the @c a_params array. If there * is a @e tag-param present, a pointer to the parameter value is assigned * to @c a_tag field. * * @section sip_msg_struct SIP Message as a C struct * * It is not enough to represent a SIP message as a collection of headers * following each other. The programmer also needs a convenient way to * access certain headers at the SIP message level, for example, accessing * directly the @From header instead of going through all headers and * examining their name. The structured view to the SIP message is provided * via a C struct with type #sip_t. * * In other words, a single message is represented by two types, first type * (#msg_t) is private to the msg module and inaccessable by an application * programmer, second (#sip_t) is a public structure containing the parsed * headers. * * The #sip_t structure is defined as follows: * @code * typedef struct sip_s { * msg_common_t sip_common[1]; // Used with recursive inclusion * msg_pub_t *sip_next; // Ditto * void *sip_user; // Application data * unsigned sip_size; * int sip_flags; * * sip_error_t *sip_error; // Erroneous headers * * sip_request_t *sip_request; // Request line * sip_status_t *sip_status; // Status line * * sip_via_t *sip_via; // @Via (v) * sip_route_t *sip_route; // @Route * sip_record_route_t *sip_record_route; // @RecordRoute * sip_max_forwards_t *sip_max_forwards; // @MaxForwards * ... * } sip_t; * @endcode * * As you can see above, the public #sip_t structure contains the common * header members that are also found in the beginning of a header * structure. The @e sip_size indicates the size of the structure - the * application can extend the parser and #sip_t structure beyond the * original size. The @e sip_flags contains various flags used during the * parsing and printing process. They are documented in the . These * boilerplate members are followed by the pointers to various message * elements and headers. * * @note Within the @b msg module, the public structure is known as * #msg_pub_t. The application programmer can cast a #msg_t pointer to * #sip_t with sip_object() function (or macro). * * * @section sip_parsing_example Result of Parsing Process * * Let us now show how a simple message is parsed and presented to the * applications. As an exampe, we choose a BYE message with only the * mandatory fields included: * @code * BYE sip:joe@example.com SIP/2.0 * Via: SIP/2.0/UDP sip.example.edu;branch=d7f2e89c.74a72681 * Via: SIP/2.0/UDP pc104.example.edu:1030;maddr=110.213.33.19 * From: Bobby Brown ;tag=77241a86 * To: Joe User ;tag=7c6276c1 * Call-ID: 4c4e911b@pc104.example.edu * CSeq: 2 * @endcode * * The figure below shows the layout of the BYE message above after parsing: * * @image html sip-parser2.gif BYE message and its representation in C * @image latex sip-parser2.eps BYE message and its representation in C * * The leftmost box represents the message of type #msg_t. Next box from * the left reprents the #sip_t structure, which contains pointers to a * header objects. The next column contains the header objects. There is * one header object for each message fragment. The rightmost box represents * the I/O buffer used when the message was received. Note that the I/O * buffer may be non-continous and composed of many separate memory areas. * * The message object has link to the public message structure (@a * m_object), to the dual-linked fragment chain (@a m_frags) and to the I/O * buffer (@a m_buffer). The public message header structure contains * pointers to the headers according to their type. If there are multiple * headers of the same type (like there are two @Via headers in the above * message), the headers are put into a single-linked list. * * Each fragment has pointers to successing and preceding fragment. It also * contains pointer to the corresponding data within the I/O buffer and its * length. * * The main purpose of the fragment chain is to preserve the original order * of the headers. If there were an third @Via header after @CSeq in the * message, the fragment representing it would be after the @CSeq header in * the fragment chain but after the second @Via in the header list. * */ /**@defgroup sip_headers SIP Headers * * SIP headers and other SIP message elements. * * For each SIP header recognized by the SIP module, there is a header * structure containing the parsed value.
