* 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.

* 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.

| | | | ... 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.

| | | | | 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.

* Split of LAPDm into a core part and a GSM specific partroot2011-10-103-1621/+2456
| | | | | | | | | | | | | | Instead of mixing together the GSM layer 1 interface and RSL interface with the implementation of LAPD, the core function of LAPD is now extracted from LAPDm. The core implementation is now in lapd_core.c and lapd_core.h respectively. The lapd_core.c implements exactly one datalink instance for one SAP. The surrounding implementation "lapdm.c" codes/decodes the layer 2 headers and handles multiplexing and datalink instances, as well as translates primitives from/to RSL layer. lapd_core.c can now be used for other LAPD implementations.
