2017-11-13Fix/Update copyright notices; Add SPDX annotationHarald Welte1-0/+2
Let's fix some erroneous/accidential references to wrong license, update copyright information where applicable and introduce a SPDX-License-Identifier to all files. Change-Id: I39af26c6aaaf5c926966391f6565fc5936be21af
2017-06-23doxygen: unify use of \file across the boardNeels Hofmeyr1-4/+5
Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec).

2017-06-23doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr1-35/+35
Especially for short descriptions, it is annoying to have to type \brief for every single API doc. Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes the first sentence of an API doc as the brief description. Change-Id: I11a8a821b065a128108641a2a63fb5a2b1916e87
2017-06-12update/extend doxygen documentationHarald Welte1-35/+87
It's a pity that even with this patch we still are fare away from having the whole API documented. However, at least we have a more solid foundation. Updates not only extend the documentation, but also make sure it is rendered properly in the doxygen HTML. Change-Id: I1344bd1a6869fb00de7c1899a8db93bba9bafce3
2014-01-13gsm/gsm48ie: Fix range 256 W[i] decoding0.6.5Jacob Erlbeck1-4/+4
Currently w[14]/w[15] and w[18]/w[19] are swapped in range 256 format decoding in gsm48_decode_freq_list(). This patch fixes this. Sponsored-by: On-Waves ehf
2012-08-24GSM 04.08: Add support for parsing CSD related bearer capabilitiesHarald Welte1-5/+90
Also adds a test case for both encoder and decoder of this IE

2011-09-02gsm/gsm48_ie: Fix other range format decodingAndreas.Eversberg1-66/+63
As it turns out, the other range were affected too, so Anreas wrote the fix for them as well. Written-by: Andreas.Eversberg <jolly@eversberg.eu> Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2011-09-01gsm/gsm48_ie: Fix Range 256 format decodingSylvain Munaut1-20/+35
From the mail: --- appended is another patch for fixing a bug in the calculation of the frequency lists. This time the patch is for the "Range 256 format". The problem is that the operand for the "smod" operation might be negative, in this case the simplified version won't work as expected. In the patch I introduced a separate function for "smod" which takes care of the sign. I have not yet checked if the other formats are also affected, this would be the case if the "smod" operand can be negative. There might be other solutions to fix the problem without the need for a separate function, however I have not thought further about it. A test vector is the following frequency list ("Range 256 format", first byte is the length): 09 8b 1c 83 8c 15 ef 02 2d 30 The correct ARFCNs are 569 571 576 578 586 608 712 715 719 The uncorrected version would instead return: 444 457 460 464 569 576 578 586 608 This means four ARFCNs are wrong which will cause problems if for example the frequency list contains the ARFCNs for hopping. ---- Written-by: Dieter Spaar <spaar@mirider.augusta.de> Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

2011-03-23include: reorganize headers file to include/osmocom/[gsm|core]0.2.0Pablo Neira Ayuso1-6/+6
This patch moves all GSM-specific definitions to include/osmocom/gsm. Moreover, the headers in include/osmocore/ have been moved to include/osmocom/core. This has been proposed by Harald Welte and Sylvain Munaunt. Tested with `make distcheck'. Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
2011-03-23This patch moves the GSM-specific functions to the new libraryPablo Neira Ayuso1-0/+1095
libosmogsm which is provided by libosmocore. I have also moved generate_backtrace() to backtrace.c instead of gsm_utils.c, otherwise the timer and msgfile tests depend on libosmogsm. Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
