* add milenage internal headers to ensure 'make dist' worksHarald Welte2011-12-071-0/+5
|
* Auth: Import milenage implementation from hostap (Jouni Malinen)Harald Welte2011-12-0614-3/+1659
| | | | ... and add integration into the osmo_auth core.
* Add a generic abstraction for GSM/3G authentication algorithmsHarald Welte2011-12-063-1/+141
| | | | | Indiidual algorithms can be implemented as plugins. libosmogsm itself only provides COMP128v1 via this generic interface.
* comp128: mark ki and srand as 'const' input parametersHarald Welte2011-12-061-1/+1
|
* increment LIBVERSION of libosmocore for new apiHarald Welte2011-12-011-1/+1
|
* SMS: export gsm411_bcdify() and gsm411_unbcdify() functionsHarald Welte2011-12-011-20/+20
| | | | | The same functions are e.g. required by the NITZ code in 04.08, and we don't want copy+paste.
* libosmocore: Update LIBVERSION because of ABI chaangesSylvain Munaut2011-11-241-1/+1
| | | | | | The recent convolutional code changes break the ABI. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

* core/conv: Add support for other termination types (trunc & tail biting)Sylvain Munaut2011-11-241-32/+94
| | | | | | | | Note that this breaks the ABI and the low level API. But it shouldn't break the high level API, nor the conv code definitions (because fields default to 0, and for new fields '0' is the previous behavior) Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
* core/conv: Really only consider error for non-zero soft valuesSylvain Munaut2011-11-241-3/+6
| | | | | | | | This should have been done with 1dd7c84733b20ba776510369e9daba1a822c5b44 but somehow was missed and only applied to the 'finish' method and not the 'scan' method. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

* gsm/sms: Rewrite of SMR process, extracted from OpenBSCAndreas Eversberg2011-11-122-1/+452
| | | | | | | | | | | 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.
