* TLV: add new "vTvLV" type for GANHarald Welte2012-07-142-1/+22
| | | | | | | | | | | | | This new TLV type is specific to TS 44.318. Contrary to the TvLV type of TS 08.16/08.18, it has an inverted meaning of the extension (0x80) bit: * if the extension bit is not set, 1-byte length * if the extension bit is set, 2-byte length Futhermore, it has support for variable-length tags, where the tag part can be optionally two bytes in length. As this esoteric option hasn't been seen in the wild yet, we only add encoding support but skip decoding for now.
* gsm48_decode_lai(): return real integers for mcc/mnc, not hex!Harald Welte2012-07-131-6/+13
| | | | This is to make it orthogonal with gsm48_encode_lai()
* add gsm48_decode_lai() to map fileHarald Welte2012-07-131-0/+1
|
* import gsm48_decode_lai() function from osmocom-bb/mobile sysinfo.cHarald Welte2012-07-131-0/+14

* 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>
* ganc: add value_strings for GAN message type and protocol discriminatorHarald Welte2012-06-243-1/+81
|
* LAPDm: Ensure there is no payload in DISC framesHarald Welte2012-04-261-1/+6
| | | | | | When we send DISC frames (especially generated from RSL), we don't want any remaining bytes from the RSL message showing up as bogus DISC payload.
* doc: Fix the Doxygen section endingsSylvain Munaut2012-04-185-5/+5

* libosmogsm: Add tvlv_att_def to exported symbolsHarald Welte2012-04-051-0/+1
|
* misc: Fix make distcheck, add the new libosmogsm.map file to the tarballHolger Hans Peter Freyther2012-04-051-0/+2
|
* lapdm: fix RSL message format in RLL ERROR INDICATIONHarald Welte2012-04-051-1/+0
| | | | | | In rsl_rll_error() we don't need to re-set the msg->l2h as that would corrupt the message. The recipient would interpret any cause value as 0.
* libosmogsm: Introduce explicit list of exported symbolsHarald Welte2012-04-043-3/+233
| | | | | | | | 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
* auth_milenage/osmo-auc-gen: compute OPC in case only OP is knownHarald Welte2012-03-211-2/+13
|
* milenage: Add function to compute OPC from OP and KHarald Welte2012-03-212-0/+17
|
* lapd: Remove unused variable t200_start in lapd_acknowledge.Holger Hans Peter Freyther2012-03-161-2/+1
| | | | | lapd_core.c: In function 'lapd_acknowledge': lapd_core.c:710:38: warning: variable 't200_start' set but not used [-Wunused-but-set-variable]
* gsm/a5: Rewrite equation doc with proper numberingSylvain Munaut2012-03-021-4/+4
| | | | | | | No idea where I copied the original from but here we use the other notation. (matches wikipedia and sources) Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
* GSM 08.08: change gsm0808_create_classmark_update() prototypeHarald Welte2012-01-261-3/+6
| | | | | The caller explicitly specifies CM2 and CM3, rather than one blob containing both.
* GSM 08.08: Cleanup the code, remove lots of magic hard-coded numbersHarald Welte2012-01-261-116/+60
| | | | | | | Rather than manually hard-coding numbers and using byte-arrays, we use the msgb_*_{push,put}() function family of libosmocore/libosmogsm. This is currently untested.
* lapdm: Make sure that the msgb_l3len(msg) == length...Holger Hans Peter Freyther2012-01-121-4/+4
| | | | | | | | | | This code should not play with the internals of the msgb like this, this code got introduced in af48bed55607931307 and is breaking the osmo-bts usecase of forwarding an RSL message. Add a test case that fails without the new code. I would prefer if we could get rid of the manipulating the msgb like this, it is prone to errors like this one.
* lapd: Warn if someone attempts to send an empty messageHolger Hans Peter Freyther2012-01-121-0/+7
| | | | | | DATA REQ with a msgb_l3len(msg) == 0 message does not make any sense, log an error and return immediately before attempting to send an empty I frame in lapd_send_i.
* lapd: Mention the L3 size of the payload being sentHolger Hans Peter Freyther2012-01-121-1/+2
|
* libosmocore/lapd: Fixed handling of sequence errors at lapd_core.cAndreas.Eversberg2012-01-101-3/+21
| | | | | | | | | | | | | | | If a sequence error is received, the N(R) variable must still be used to acknowledge previously transmitted frames. If there are two subsequent sequence errors received, ignore it. (Ignore every second subsequent error.) This happens if our reply with the REJ is too slow, so the remote gets a T200 timeout and sends another frame with a sequence error. Test showed that replying with two subsequent REJ messages could the remote L2 process to abort. Replying too slow shouldn't happen, but may happen over serial link between BB and LAPD.

* Fix generation of GPRS Routing Area in case of 3-digit MNCGus Bourg2011-12-141-1/+1
| | | | | This fixes a simple typo that causes erroneous GPRS Routing Area encoding if you use 3-digit MNCs.
* auth_core: add missing string.h include to reduce warningsHarald Welte2011-12-071-0/+1
|
* auth_core: don't use anonymous unions to make certain gcc versions happyHarald Welte2011-12-072-7/+7
|
* auth_milenage: we now copy RAND in auth_core, no need to do it twiceHarald Welte2011-12-071-1/+0
|
* auth_core: Make sure we always save the RAND in the vectorHarald Welte2011-12-071-1/+8

* 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

| | | | | The same functions are e.g. required by the NITZ code in 04.08, and we don't want copy+paste.

* 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.
