* Update doxygen annotations in libosmocoreHarald Welte2016-05-0527-186/+374
| | | | | This adds and improves doxygen API descriptions all over libosmocore, reducing the 'white spots' that don't have any documentation.
* add new header file for TS 23.003Harald Welte2016-05-052-0/+24
|
* import gsm_04_08_gprs.[ch] from openbsc.gitHarald Welte2016-05-055-1/+546
| | | | | | 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 Welte2016-05-052-0/+16
| | | | | 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().
* auth_core: Add osmo_auth_3g_from_2g() to compute CK+IK from KcHarald Welte2016-05-052-0/+42
| | | | | This function performs the C5+C4 conversion to derive UMTS key material from a 2G-only subscriber.
* conv_gen: Use python2 to execute the scriptHolger Hans Peter Freyther2016-04-292-2/+2
| | | | | | | | | | | | | | | | | | | | | The script does not work with python3: $ python3 utils/conv_gen.py File "utils/conv_gen.py", line 124 def _print_term(self, fi, num_states, pack = False): Second there is no 'python' on FreeBSD and one needs to select the major version to use. GEN conv_cs3_gen.c GEN conv_xcch_gen.c GEN conv_cs2_gen.c python: not found python: not found python: not found By using python2 we solve both issues. On Debian python2 is located inside the python-minimal package.
* add two missing files (gsm0503.h / conv_gen.py) to previous commitHarald Welte2016-04-292-0/+568

* Add code generator for convolutional codesMax Suraev msuraev@sysmocom.de2016-04-297-195/+113
| | | | | | | | | | | | | | | | 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
* milenage/aes: Address undefined behavior on bitshiftHolger Hans Peter Freyther2016-04-241-1/+1

* doxygen: Remove the tag file on uninstall as wellHolger Hans Peter Freyther2016-04-241-1/+1
| | | | | | | | | | | Hopefully last patch: ERROR: files left in build directory after distclean: ./doc/libosmocore.tag ./doc/libosmovty.tag ./doc/libosmogsm.tag ./doc/libosmocodec.tag Makefile:800: recipe for target 'distcleancheck' failed
* doxygen: Next try to fix the uninstall handlingHolger Hans Peter Freyther2016-04-241-1/+1
| | | | Use /* to remove the files
* doxygen: Try to uninstall the search files as wellHolger Hans Peter Freyther2016-04-241-1/+1
| | | | | | | | | | | Try to fix this by putting the search directory first as I don't know how to pass -r to the RM command. rm -f doc/{core,gsm,vty,codec}/{html,latex}/* doc/html.tar doc/{core,gsm,vty,codec}/doxygen_sqlite3.db rm: cannot remove ‘doc/core/html/search’: Is a directory rm: cannot remove ‘doc/gsm/html/search’: Is a directory rm: cannot remove ‘doc/vty/html/search’: Is a directory rm: cannot remove ‘doc/codec/html/search’: Is a directory

* Add function for appending range1024 to bitvecMax2016-04-234-1/+51
| | | | | Add convenience function to append range1024 encoded data (see 3GPP TS 44.018 Annex J) to a given bitvec.
* Deprecate comp128Max2016-04-223-4/+13
| | | | | Mark function as deprecated to discourage its usage: people should use generic API in osmocom/crypt/auth.h
* Deprecate osmo_a5_1 and osmo_a5_2Max2016-04-222-52/+61
| | | | | Mark the functions as deprecated to discourage their use: people should use unified osmo_a5 which supports all the A5/1-4 ciphers.
* Improve code reuseMax2016-04-221-32/+3
| | | | Use generic functions covered by testsuit for SQN calculations.
* Update internal GPRS cipher APIMax2016-04-224-5/+30
| | | | | Update internal API (for GPRS cipher implementors): make it compliant with ETSI TS 155.22. External API left untouched.
* Addditional classmark check against A5/4 supportMax2016-04-221-1/+13
| | | | | Add classmark check function according to GSM 04.08 Chapter 10.5.1.7 Fix interface to use unsigned for unsigned value.
* Add function to get osmo_earfcn bit sizeMax2016-04-163-0/+26
| | | | | | This function returns the number of bits necessary to pack osmo_earfcn into Repeated E-UTRAN Neighbour Cells IE (3GPP TS 44.018 Table 10.5.2.33b.1).
* logging.c: assert category_token allocation (CID #57871)Neels Hofmeyr2016-04-161-0/+1

* jenkins: Enable tracing and error handling in bashHolger Hans Peter Freyther2016-04-131-0/+2
| | | | | Like jenkins we want to see what is actually being executed and fail if a subcommand has failed.
* jenkins: Add build script used by jenkins on our public CIHolger Hans Peter Freyther2016-04-131-0/+6
| | | | | | The actual script (removed unused and commented out handling) as invoked by jenkins. This can be used to locally try to reproduce the build.
* Add ubit <-> sbit convertorsMax2016-04-123-21/+29
| | | | | Move functions for conversion between soft and unpacked bits to main library as they are generally useful.
* gb: Add bssgp_pdu_str to libosmogb namespaceMax2016-04-121-0/+1
| | | | [hfreyther: To be used by osmo-pcu]
* Add missing docs for bssgp bvc reset vty commandMax2016-04-071-2/+8
| | | | Fixes the build failure with extended tests enabled.
* Add vty command to explicitly reset given BVCIMax2016-04-051-0/+20
| | | | | It's useful for debugging and is similar to existing reset command for nsvc.
* 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 Freyther2016-03-312-32/+57
| | | | | | | | | | | | | | | | 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
* Export names for gsm_chan_t and gsm48_chan_modeMax2016-03-304-1/+34
| | | | This can be used with get_value_string() to improve debugging output.
* sim: Fix compiler warning and by this fixing the test resultHolger Hans Peter Freyther2016-03-211-0/+1

* sim: make osim_reader_ops publicHarald Welte2016-03-192-9/+7
|
* Add new osmo_fd_get_by_fd() functionHarald Welte2016-03-192-0/+14
| | | | | | This function can be used to obtain the osmo_fd corresponding to a given fd. The latter can be useful when integrating libosmocore main loop with other libraries.
* sim: Add simplistic unit test for APDU class tablesHarald Welte2016-03-175-2/+76
|
* sim: add class_tables / card profilesHarald Welte2016-03-174-2/+359
| | | | | The tables permit code to determine the APDU class of an APDU based on it APDU/TPDU header (CLA/INS/P1/P2/P3).
* Improve BSSGP debug outputMax2016-03-172-17/+17
| | | | | Print string representation of Cause IE and PDU type instead of numerical value.
* add missing #include <stdbool.h>Harald Welte2016-03-171-0/+1

* Add basic EARFCN supportMax2016-03-173-1/+85
| | | | | | Add structure representing group of EARFCNs with common priority, threshold etc. Add functions to populate this structure.
* Add function to add bits from array to bitvecMax2016-03-174-0/+119
| | | | | | | | | 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 Hofmeyr2016-03-153-21/+39
| | | | | | | | | | 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: switch to r99 msg type bitmasks by defaultNeels Hofmeyr2016-03-151-1/+1
| | | | | [hfreyther: Separated from the previous patch to allow an easy revert]
* 04.08: add inline funcs for pdisc + msg type bitmasksNeels Hofmeyr2016-03-152-2/+58
| | | | | | | | | | | | | | | | 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]
* Add helper function to convert numerical BSSGP PDU type to stringMax2016-03-112-0/+47
