* Add helper functions for AMR codecMax2016-05-311-0/+31
| | | | | | | | | | | | | | | | | | | * add functions to encode/decode various codec paramters from RTP payload with AMR frame according to RFC 4867 * those functions are extended version based on code from osmo-bts' amr.c by Andreas Eversberg * add corresponding enum types and strings for logging * add regression tests It's useful both to replace manual parsing in osmo-bts with fuctions covered by test suite and as a debugging helpers for issues related to AMR.

* logging: Use __BASE_FILE__ instead of __FILE__Harald Welte2016-05-122-5/+5
| | | | | | | | | | | | | | Apparently __FILE__ expands to nasty '../../..' paths when BUILDDIR != SRCDIR. This in turn leads to ugly log lines like: <0000> ../../../../osmo-bts/src/common/rsl.c:1642 (bts=0,trx=0,ts=0,ss=0) Handing RLL msg UNIT_DATA_IND from LAPDm to MEAS REP Where we certainly wouldn't want the "../../../../osmo-bts" part.

* GSUP: Add support for RAND in SendAuthInfo.reqHarald Welte2016-05-061-0/+1
| | | | | | In the autentication re-sync case, we need not only the AUTS from the MS/UE, but also the RAND that we sent as part of the failed authentication challenge.
* GSUP: Add OSMO_GSUP_CN_DOMAIN_IE to differentiate CS and PS planeHarald Welte2016-05-061-0/+7
| | | | | We're starting to use GSUP for circuit-switched (CS) plane, so we need to differentiate the two planes somehow from each other.
* import gprs_gsup_message.[ch] from openbsc as gsup.[ch]Harald Welte2016-05-063-1/+142
| | | | | | | Move those routines from OpenBSC to libosmogsm, so they can be re-used from other programs. I think it was a mistake to add them only inside the openbsc repository in the first place. We need to pay more attention to this in the future.

| | | | | These routines have nothing to do with specifically the BSC, so import them to the TLV parser we keep in libosmogsm.
* Update doxygen annotations in libosmocoreHarald Welte2016-05-059-139/+162
| | | | | This adds and improves doxygen API descriptions all over libosmocore, reducing the 'white spots' that don't have any documentation.

* import gsm_04_08_gprs.[ch] from openbsc.gitHarald Welte2016-05-052-0/+398
| | | | | | The definitions in this header file (and associated strings in the c file) are generic about the GPRS Layer3 signalling protocols, and thus should be part of the library.
* Add log_fini() function to release all memory allocated by logging frameworkHarald Welte2016-05-051-0/+1
| | | | | This is e.g. quite useful to call at the end of test code, in order to show that all memory allocated actually is released before exit().

* Add code generator for convolutional codesMax Suraev msuraev@sysmocom.de2016-04-291-0/+1
| | | | | | | | | | | | | | | | Add python utility to generate .c code with convolutional encoder/decoder based on polynomial description of the code. If argument given it'll be interpreted as intended output directory, otherwise current working directory is used. Codes for *CCH, CS2/3 and TCH/AFS are generated. Corresponding manual implementations are removed from tests. This introduce build-time dependency on python. The main work for this patch was generously contributed by Sylvain Munaut. Fixes: OS#1629

* vty: Make a reservation for the osmo-sip-connectorHolger Hans Peter Freyther2016-03-311-0/+1
| | | | | The osmo-sip-connector is a new application and is a MNCC to SIP bridge. It is not implementing transcoding or RTP proxying at all.
* select: Externalize fd_set filling and dispatchHolger Hans Peter Freyther2016-03-311-0/+6
| | | | | | | | | | | | | | | | To integrate with an external event loop (in this case glib) we need to allow an application to get a filled out fd_set and then dispatch it. osmo_fds and maxfds are static and I decided to keep it that way and instead create two routines to fill the fdset and then one to dispatch the result. The public header file does not include sys/select.h and we can compile the library without select, so I didn't want to require having to include this file, and used void * for the parameter. Mark the routines as inline to avoid a call from the select function. I have confirmed that inlining has an effect on x86 using Debian's gcc-4.9.2-10 compiler

* sim: add class_tables / card profilesHarald Welte2016-03-172-0/+43

* Add function to add bits from array to bitvecMax2016-03-171-0/+3
| | | | | | | | | Add function which adds specified number of bits from each element of array to the bit vector prefixing each addition with one and finishing entire sequence with adding 0. This is very common patter for various repetitive data structures described with CSN.1 in 3GPP standards. Corresponding test vectors and doxygen headers are added too.
* gsm48: factor out MCC+MNC BCD parsing for re-use in UMTSNeels Hofmeyr2016-03-151-0/+3
| | | | | | | | | | For 3G, I need a BCD composer/parser similar to gsm48_generate_lai()/ gsm48_decode_lai(). Those functions also handle a trivial extra member (lac) which I don't need in this way for 3G. So create new functions to take on the MCC+MNC BCD handling and call those from gsm48_generate_lai() and gsm48_decode_lai(). In this way, the 3G code in openbsc can use only the BCD functionality without code duplication.
* 04.08: add inline funcs for transaction id bitsNeels Hofmeyr2016-03-151-0/+19
| | | | | | Various users of gsm48_hdr apply the same hardcoded shifts/bitmasks to obtain the transaction ID encoded in the upper nibble of the protocol discriminator. Centralize. Patch for openbsc.git will follow.

* 04.08: add inline funcs for pdisc + msg type bitmasksNeels Hofmeyr2016-03-151-0/+56
| | | | | | | | | | | | | | | | Add inline functions for both release <= 98 and release >= 99 as well as a default define. Use the release 98 by default since the current code base uses the r98 bitmasks. These inline functions relieve callers of the decision on masking bits of the protocol discriminator and message type octets. Also add a define for the protocol discriminator extension to one octet length (GSM48_PDISC_EXTEND). Apply new pdisc function in gsm0480.c. [hfreyther: Make the hdr param const]

* log: Add conditional logging based on log_check_levelJacob Erlbeck2016-02-291-4/+20
| | | | | | | | | | | | | | Currently the LOGP/DEBUGP arguments are always evaluated even if no logging will happen at all. This can be expensive, for instance if hexdumps or pretty printed object names are generated. This causes high base load especially on embedded devices and is a major part of CPU usage e.g. of the osmo-pcu. This commit uses the log_check_level function to avoid the evaluation of the parameters if it is known in advance, that no logging entry will be generated. Sponsored-by: On-Waves ehf
* log: Add log_check_level functionJacob Erlbeck2016-02-291-0/+1
| | | | | | | | | | | | | | | | | | This commit adds this predicate function which can be used to avoid the execution of code if a certain log level is not enabled. The function will only return 0 (false), if it is sure that a logging call for the same facility and level will not produce any output. This safety criterion shall ensure, that no logging output is lost due to the use of this predicate as a guard. On the other hand, even if the predicate returns != 0 (true), no logging output might get generated by a similar logging command. Note that the current implementation is not focussed on performance, which could be improved by using a lookup table instead of iterating through every target. Sponsored-by: On-Waves ehf

* Add byte printing macrosMax2016-02-251-0/+21
| | | | | | It's sometimes handy for debugging to be able to immediately see which bits are set in a given byte. Generalize macro used for that in bitvec tests and make it available for the rest of the library.
* vty: add ctrl section for Control interface bind addressNeels Hofmeyr2016-02-253-2/+12
| | | | | | | | | | | | | | | | | | | | | | | This may seem like overkill for a mere const char * config item, but it makes the Control interface VTY commands reusable in any main() scope (inspired by libosmo-abis' VTY config). Add API functions ctrl_vty_init() and ctrl_vty_get_bind_addr(), in new files src/ctrl/control_vty.c and include/osmocom/ctrl/control_vty.h, compiled and/or installed dependent on ENABLE_VTY. Using these functions allows configuring a static const char* with the VTY commands ctrl bind A.B.C.D which callers shall subsequently use to bind the Control interface to a specific local interface address, by passing the return value of ctrl_vty_get_bind_addr() to control_interface_setup(). Add CTRL_NODE to enum node_type, "eating" RESERVED4_NODE to heed that comment on avoiding ABI changes.
* add ctrl_interface_setup_dynip() for bind addressNeels Hofmeyr2016-02-251-0/+4
| | | | | | Make the ctrl interface bind address configurable, so that it may be made available on other addresses than 127.0.0.1. The specific aim is to allow running multiple osmo-nitbs alongside each other (commits in openbsc follow).
* vty: add bind command for telnet vty lineNeels Hofmeyr2016-02-251-0/+3
| | | | | | | | | | | | | | | | | | | | Add VTY command line vty bind A.B.C.D The command merely stores the configured IP-address, which can then be used by the calling main program to set the telnet port of the VTY line. (Commits in openbsc and osmo-iuh will follow up on this.) Add function vty_get_bind_addr() to publish the address in the vty.h API. Add static vty_bind_addr to store. For allocation/freeing reasons, a NULL address defaults to 127.0.0.1. BTW, I decided against allowing keywords 'any' and 'localhost' in place of an actual IP address to make sure a written config is always identical to the parsed config.
