2017-02-09utils/conv_gen.py: improve application flexibilityVadim Yanitskiy1-8/+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
2017-02-08fix various compiler warnings (on FreeBSD-11.0)Harald Welte1-3/+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
2017-02-06osmo-auc-gen: cmdline help: list algorithms; error messagesNeels Hofmeyr1-1/+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
2017-02-04osmo-auc-gen: cosmetic: clarify output upon AUTSNeels Hofmeyr1-1/+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
2017-02-02GSUP, OAP, osmo-gen-vec: fix AUTS length to 14, not 16Neels Hofmeyr1-1/+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
2016-12-24utils/conv_gen.py: separate code definitionsVadim Yanitskiy2-714/+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
2016-12-24utils/conv_gen.py: use shared tables if possibleVadim Yanitskiy1-37/+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
2016-11-26osmo-sim-test.c: Fix rmsg checkHarald Welte1-1/+1

2016-11-02utils/conv_gen.py: explicitly import reduce()Vadim Yanitskiy1-0/+1
This change finally makes the script able to be executed in Python 3 environment. Due to new Python 3 restrictions, the reduce() should be imported explicitly. Change-Id: Icbc81c29f1a226aeed2c1245a5d60809fe124005
2016-11-02utils/conv_gen.py: don't mix print and write()Vadim Yanitskiy1-32/+34

2016-10-23utils/conv_gen.py: improve output formattingVadim Yanitskiy1-6/+32
To keep the generated tables readable, line with should be limited. So, now there are the following limitations: - _print_term(): up to 12 numbers per line, - _print_puncture(): up to 12 numbers per line, - _print_x(): up to 4 blocks per line. Change-Id: I95256c4ad402a3c088bdb6c5a5cda8b17c31881c
2016-10-23utils/conv_gen.py: generate a single fileVadim Yanitskiy1-318/+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
