* Add function to check GMM encryptabilityMax2016-07-071-0/+25
| | | | | | | | Check if particular GMM message can be encrypted according to 3GPP TS 24.008 ยง 4.7.1.2 Related: OS#1582 Change-Id: I7ad0e03c2c738d174dd6bc3453f332eeb8da1e7d
* Revert "gsm48: move to hex TMSI representation"Holger Freyther2016-05-201-1/+2
| | | | | | | | | | | | | | | | | This is a "flag" day change. Old OpenBSC break with new libosmocore because suddenly there is the 0x in front. I am afraid we need to find a better solution here. I think we will need to create a gsm48_mi_to_string variant that takes a mode parameter to enable the TMSI mode and deprecate the old method. Right now we should not break old versions of OpenBSC. This reverts commit 78ad042f94afd5bf7de477ae634e9d2fdd9c9dc4.

* gsm48: move to hex TMSI representationVadim Yanitskiy2016-05-201-2/+1
| | | | | | | | | | | | | Previously, we traditionally displayed a TMSI in its integer representation, which is quite unusual in the telecom world. A TMSI is normally printed as a series of 8 hex digits.

* gsm48: factor out MCC+MNC BCD parsing for re-use in UMTSNeels Hofmeyr2016-03-151-21/+34
| | | | | | | | | | For 3G, I need a BCD composer/parser similar to gsm48_generate_lai()/ gsm48_decode_lai(). Those functions also handle a trivial extra member (lac) which I don't need in this way for 3G. So create new functions to take on the MCC+MNC BCD handling and call those from gsm48_generate_lai() and gsm48_decode_lai(). In this way, the 3G code in openbsc can use only the BCD functionality without code duplication.

* gsm48: Added 'Network Daylight Saving Time' info elementJacob Erlbeck2013-09-161-0/+1
| | | | | | | | This information element has been added to the MM Information message in GSM24.008. This patch adds it to the tlv_definition to keep the TLV parser from breaking. Ticket: OW#978
* gsm0408: Avoid unaligned memory access in gsm48_generate_mid_from_tmsiHolger Hans Peter Freyther2013-07-031-2/+2
| | | | | | | | The &buf[3] is unlikely to be aligned properly. Use memcpy instead of an assignment. Add a small testcase that verifies that I didn't mess up the conversion. Alignment trap: osmo-nitb (3293) PC=0x492b7094 Instr=0xe5803003 Address=0xbeb259db FSR 0x801
* GSM48: Avoid unaligned access in gsm48_construct_raAndreas Eversberg2012-11-051-1/+3
| | | | | This avoids an unaligned access on platforms that don't support them, such as ARMv4/ARMv5.

| | | | | | | | | | | | This patch moves all GSM-specific definitions to include/osmocom/gsm. Moreover, the headers in include/osmocore/ have been moved to include/osmocom/core.

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>
