* libosmocoding: migrate transcoding routines from OsmoBTSVadim Yanitskiy2017-03-071-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | There are some projects, such as GR-GSM and OsmocomBB, which would benefit from using one shared implementation of GSM 05.03 code. So, this commit introduces a new sub-library called libosmocoding, which (for now) provides GSM, GPRS and EDGE transcoding routines, migrated from OsmoBTS. The original GSM 05.03 code from OsmoBTS was relicensed under GPLv2-or-later with permission of copyright holders (Andreas Eversberg, Alexander Chemeris and Tom Tsou). The following data types are currently supported: - xCCH - PDTCH (CS 1-4 and MCS 1-9) - TCH/FR - TCH/HR - TCH/AFS - RCH/AHS - RACH - SCH Change-Id: I0c3256b87686d878e4e716d12393cad5924fdfa1

* utils/conv_gen.py: improve application flexibilityVadim Yanitskiy2017-02-091-8/+38
| | | | | | | | | | 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
* fix various compiler warnings (on FreeBSD-11.0)Harald Welte2017-02-081-3/+3
| | | | | | | FreeBSD 11.0 uses clang version 3.8.0 which spits various warnings during libosmocore compilation. Let's clean this up a bit. Change-Id: Ic14572e6970bd0b8916604fabf807f1608fa07e5
* osmo-auc-gen: cmdline help: list algorithms; error messagesNeels Hofmeyr2017-02-061-1/+10
| | | | | | | | | | | | In the -h help output, list the names of available algorithms. In case of option parsing failure, also print help() (so that e.g. for a typo in the algorithm, the list of algorithms is printed along with the error message). If there are -2/-3 or -a missing, show an error message that explains this. Change-Id: I76732b28d7a553a6293d1707fe398d28b5ef4886
* osmo-auc-gen: cosmetic: clarify output upon AUTSNeels Hofmeyr2017-02-041-1/+14
| | | | | | | | | | | | | | | | | | | | | When calculating a re-sync vector using AUTS, osmo-gen-vec used to print SQN.MS + 2, the new SQN after vector generation, labeled 'SEQ.MS'. Firstly, s/SEQ/SQN. Secondly, print SQN.MS as umts.sqn - 2, which is the actual SQN recovered from the AUTS. As explained in the comment, SQN.MS + 1 is used to generate the vector, and then umts.sqn is increased a second time to indicate the next SQN. With AUTS calculated from SQN.MS == 23, the output was: AUTS success: SEQ.MS = 25 Output now: AUTS success: SQN.MS = 23, generated vector with SQN = 24, next SQN = 25 Change-Id: I881bbe8246a5e7d3a5065b4b5b533255723b1a9e
* GSUP, OAP, osmo-gen-vec: fix AUTS length to 14, not 16Neels Hofmeyr2017-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS to our osmo_auth_gen_vec_auts() API. According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14 bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2 and AUTS being the V = 14. It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But writing 16 bytes to a GSUP struct is a potential problem when passing in a 14 byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer. The API implies the length, so far to be 16, so passing in a 14 byte buffer to GSUP would require copying to a larger buffer first. Fix this by using a length of 14 for AUTS everywhere instead. This constitues an ABI breakage, we may handle it as a "fix before an official release", otherwise we need a version bump. The OAP protocol document has also been updated, needs an update in the osmo-gsm-manuals as well. Change-Id: If25b173d9ec57ea4c504d860954912b7d82af455
* utils/conv_gen.py: separate code definitionsVadim Yanitskiy2016-12-242-714/+728
| | | | | | | | | This change separates the convolutional code definitions from the code generator logic, allowing us to make further changes in more specific way. For example, adding some new codes, you change the conv_codes.py only because such change isn't related to the generator. Change-Id: I3428561251b7d7a180d1e9b6fcaad50bdbbc37fa
* utils/conv_gen.py: use shared tables if possibleVadim Yanitskiy2016-12-241-37/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces the memory usage optimization, mentioned in d2d9760c08f35a231d32f0ebeb73b2927e5573b3. The aim is to make code generator able to detect, whether the same tables are used by several convolutional code definitions, and prevent one from writing these tables multiple times. For now, the detection process isn't fully automatic, so all shared polynomials should be placed inside the 'shared_polys' dictionary, for example: shared_polys = { "xcch" : [ ( G0, 1 ), ( G1, 1 ), ], "mcs" : [ ( G4, 1 ), ( G7, 1 ), ( G5, 1 ), ], } Change-Id: I84760f5cdfdaece376b801d2e6cb2954ee875a3b

* utils/conv_gen.py: explicitly import reduce()Vadim Yanitskiy2016-11-021-0/+1

* utils/conv_gen.py: improve output formattingVadim Yanitskiy2016-10-231-6/+32
| | | | | | | | | | | To keep the generated tables readable, line with should be limited.

* utils/conv_gen.py: generate a single fileVadim Yanitskiy2016-10-231-318/+315
| | | | | | | | | | | | | | | | 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.

Now it generates the following format: Change-Id: I2805615e0c2087ca632e0658b37a9e06929620b6 AUTN: f755bc47ded00000f9ed4b3f6c2a976f Reviewed-on: https://gerrit.osmocom.org/164 Reviewed-by: Harald Welte <laforge@gnumonks.org> Tested-by: Jenkins Builder
