* Add header file with definitions for GSM TS 04.14 / 3GPP TS 44.014Harald Welte2017-06-121-1/+1
| | | | Change-Id: I1f4fc2761b55a4f83544c1c3793ab67fec9fc120
* add libpseudotalloc as super-simplistic talloc replacementHarald Welte2017-05-171-0/+4
| | | | | | | | | | | In tightly embedded builds (--enable-embedded), we want the ability to replace talloc with a very simple heap allocator to avoid the complexity of talloc without modifying all our code that assumes talloc. This will break the hierarchical notion of the allocator, but libosmo{core,gsm,coding,codec} don't rely on that anyway. Change-Id: Ie341034076f242a813f081919dd09d845775ad35
* gsm0808: Add utils for AoIP Transport Layer AddressPhilipp Maier2017-04-081-1/+1
| | | | | | | | | | The planned support for true A over IP requires the encoding and decoding of a so called "AoIP Transport Layer Address" element. This commt adds parsing functionality and tests for the element mentioned above, however, it is not yet actively used. Change-Id: I57933b0a06a3f54ec2a41e6ecb6ced9fbbc89332
* build: fix build dependencies for generated sourcesNeels Hofmeyr2017-03-201-1/+3
| | | | | | | | Ensure that a changed conv_gen.py and/or conv_codes_gsm.py result in regeneration of the gsm0503* generated sources. Before this patch, manual cleaning of the generated files was necessary to benefit from a code update. Change-Id: Ib4328662c21280c0ea6aa9391a64ada2c6598704
* utils/conv_gen.py: improve application flexibilityVadim Yanitskiy2017-02-091-1/+1
| | | | | | | | | | This change makes the conv_gen application more interactive and flexible, allowing to generate not only code definitions but also the test vectors and header files in the future. Moreover, it becomes possible to select exact code family, such as GSM, GMR etc. Change-Id: I0b476b00234c17f78b41d695cf3bfd13edb64c28
* Catch-up with git version tagsMax2016-12-211-2/+3
| | | | | | | | | | | | * update debian/changelog * update TODO-RELEASE * add comments to Makefile.am and TODO-RELEASE to simplify the process in future * add link to libtool docs to Makefile.am to simplify LIBVERSION maintenance Related: OS#1861 Change-Id: I22c257e357f597519120232d742d6a61289db021
* import oap message parsing / encoding from openbsc.git; AGPL->GPLHarald Welte2016-12-111-1/+1
| | | | | | | | | | | | | | | | | | | In the process, also: * Change the license from AGPLv3 to GPLv2-or-later; * correct spelling of 'sysmocom' to lowercase; * add '2016' to the copyright; * rename to osmo_*; * add API docs; * add logging category DLOAP: define id and add to internal_cat; * redirect all oap.c logging to DLOAP. A unit test will follow in a subsequent patch, since it needs a minor tweak for decoding of boolean values. The related openbsc change-id is I2f06aaa6eb54eafa860cfed8e72e41d82ff1c4cf.

* utils/conv_gen.py: generate a single fileVadim Yanitskiy2016-10-231-7/+5
| | | | | | | | | | | | | | | | Instead of generating every convolutional code into a separate file (such as conv_xcch_gen.c, conv_cs3_gen.c), it is better to have a single file, containing all definitions, because as many convolutional codes we add, as many entries we will have to add into 'src/gsm/Makefile.am'. This approach increases readability of the Makefile.am, and also makes us able to share some data between some convolutional code definitions. For example: xCCH, RACH, SCH, TCH/F, both CS2 and CS3 may use the same *_state[][2] and *_output[][2] arrays within a single file. This optimization is currently WIP. Change-Id: Ib4e4ee5fdde38429e68e3b2fa50ec03a18f59daa
* gsm/Makefile.am: use proper top_builddir/top_srcdir pathsNeels Hofmeyr2016-10-121-3/+3
| | | | | | | | | | This fixes the conv*gen.c targets when building in a different directory than the source tree. Notably, building in a different dir worked when the generated sources were already present from a previous build inside the source directory. Change-Id: I5a9b780ad4ba607ea39854dcf7207ed05f5447bc
* egprs: Add CPS tables from TS 04.60Tom Tsou2016-07-251-1/+1
| | | | | | | | Includes EGPRS coding and puncturing scheme (CPS) tables from 3GPP TS 04.60. Currently osmo-bts-trx is the only user of CPS table values, but this may change with gprsdecode and other utilities. Change-Id: I09fe6514a0e2e51bb3206f8387633f7e0255345f
* Add GEA3 & GEA4 ciphersMax2016-07-111-2/+2
| | | | | | | | | | | Corresponding test code include both official test vectors from the specs and data from over-the-air tests. This obsoletes libosmo-crypt-a53 as it was last missing piece unimplemented in libosmogsm. Change-Id: I939e4f6b91b4a7c591ef3761fe2d46ed1c2fb2d3 Related: OS#1582
* import gprs_gsup_message.[ch] from openbsc as gsup.[ch]Harald Welte2016-05-061-1/+2
| | | | | | | 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.
* import gsm_04_08_gprs.[ch] from openbsc.gitHarald Welte2016-05-051-1/+1
| | | | | | 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.
* conv_gen: Use python2 to execute the scriptHolger Hans Peter Freyther2016-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | 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 code generator for convolutional codesMax Suraev msuraev@sysmocom.de2016-04-291-0/+8
| | | | | | | | | | | | | | | | 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
* remove our internal copy of talloc, use system libtallocHarald Welte2015-12-051-2/+2
| | | | | | | Shipping our own private copy of talloc was a good idea in 2008, when it was not readily available on most target platforms. Today, the situation is quite different, as it is a standard library on major Linux distributions.
* build: have a disable-static build succeedJan Engelhardt2015-09-161-2/+6
| | | | | | | | | | | | | When using configure --disable-static, no libosmogsm.a will be created, and the tests fail to link because symbols like _a5_3 and _a5_4 are not exported through the only remaining libosmogsm.so. A method to overcome this is an intermediate private non-distributed library, examples of which are present in e.g. libabc, kmod and systemd. With this, disable-static can now be the default and practical compile time be halved.
* Add APN utility function to libosmogsmHarald Welte2015-05-251-1/+1
| | | | | | The current functions are used to 'qualify' an APN from the user-supplied APN name (name identifier) towards the fully-qualified APN name which is used in the .grps DNS zone.
* add gsm0341_test to generate SMSCB hex stringsHarald Welte2014-12-291-1/+1
| | | | Those hex strings can then be copy+pasted into the OSmoNITB VTY
* build: remove unused all_includes and use AM_CPPFLAGSJan Engelhardt2014-10-031-1/+2
| | | | | Preprocessor flags are best placed in AM_CPPFLAGS. Remove use of the unused all_includes variable, which is never set.
* misc: Look into the build directory for generated filesHolger Hans Peter Freyther2014-09-251-1/+1
| | | | | | the bits/crc files are not inside the sourcedirectory but will end in the build directory. Go and look there as well. This somehow doesn't fail with make distcheck but when building for Yocto Dizzy.
* prepare for 0.7.0 releaseHarald Welte2014-08-211-1/+1
|
* ipa: rename functions for consistencyHarald Welte2014-08-201-1/+1
| | | | | | | | As we are breaking builds by moving functions from libosmo-abis to libosmocore anyway, we might as well give functions more appropriate names. ipaccess is a company, while IPA is the multiplex protocol, and CCM is the protocol used for establishing identities on the IPA multiplex.
* import various generic IPA related functions from libosmo-abisHarald Welte2014-08-201-1/+1
| | | | | | | | | libosmo-abis is about forming A-bis interfaces/lines by means of E1 or the IPA multiplex (or possibly other link layers). The IPA multiplex is used in other contexts, such as the Control interface, or the A interface. In that context, it makes sense to have generic IPA related functions in libosmocore.

* build: use LT_INIT(pic-only) instead of forcing -fPIC.Diego Elio Pettenò2012-06-301-1/+1
| | | | | | | | This actually allows for the user to override the decision and at the same time supports compilers that might not be able to use -fPIC at all. Signed-off-by: Diego Elio Pettenò <flameeyes@flameeyes.eu>

* misc: Fix make distcheck, add the new libosmogsm.map file to the tarballHolger Hans Peter Freyther2012-04-051-0/+2
|
* libosmogsm: Introduce explicit list of exported symbolsHarald Welte2012-04-041-2/+2
| | | | | | | | There is now a "libosmogsm.map" file containing an explicit list of to-be-exported symbols. This should prevent us from leaking non-static symbols into the global namespace. A similar scheme should be adopted by all other osmocom libraries

* Add a generic abstraction for GSM/3G authentication algorithmsHarald Welte2011-12-061-1/+1
| | | | | Indiidual algorithms can be implemented as plugins. libosmogsm itself only provides COMP128v1 via this generic interface.

* gsm/sms: Rewrite of SMR process, extracted from OpenBSCAndreas Eversberg2011-11-121-1/+1
| | | | | | | | | | | The SMR process is used to transfer SMS TPDUs. It is now extracted from OpenBSC. It includes a real state machine now for easier debugging. Also it implements the TR1M and TR2M timers. The memory notification procedure is missing, but not required for network side.

* Split of LAPDm into a core part and a GSM specific partroot2011-10-101-1/+1
| | | | | | | | | | | | | | Instead of mixing together the GSM layer 1 interface and RSL interface with the implementation of LAPD, the core function of LAPD is now extracted from LAPDm. The core implementation is now in lapd_core.c and lapd_core.h respectively. The lapd_core.c implements exactly one datalink instance for one SAP. The surrounding implementation "lapdm.c" codes/decodes the layer 2 headers and handles multiplexing and datalink instances, as well as translates primitives from/to RSL layer. lapd_core.c can now be used for other LAPD implementations.
