2017-02-22logging: use central filter and ctx consts from libosmocoreNeels Hofmeyr6-40/+32
The LCHAN and BTS filter contexts are actually never used, so drop them until someone adds them properly. For now use only LOGGING_{FILTER,CTX}_VLR_SUBSCR. Some of these will change to _BSC_SUBSCR once struct bsc_subscriber is introduced, and later on, struct gsm_subscriber will be replaced by vlr_subscriber so that the names will match.

2017-02-19subscr_update_expire_lu(): fix (obscure) segfaultNeels Hofmeyr1-0/+10
To be paranoid, catch a NULL subscriber and/or bts in subscr_update_expire_lu(): print an error log and avoid segfault. (I'm not sure this would really happen in a normal situation.) During aggressive testing of Paging timeout, I came across this segfault in msc_release_connection() when conn->expire_timer_stopped is set but conn->subscr is NULL, at the subscr dereference after: if (conn->expire_timer_stopped) subscr_update_expire_lu(conn->subscr, conn->bts); I brought this situation about by a fabricated Paging fault, i.e. in gsm48_rx_rr_pag_resp() return 0 and don't call gsm48_handle_paging_resp() at all. Thus conn->subscr is still NULL when expire_timer_stopped is 1. When looking at CM Service Request handling, the conn->subscr is set before setting expire_timer_stopped = 1, which is a saner thing to do. But without my mad 'return 0', there is in fact no way to have a NULL subscriber there. It looks like all other code paths already do the same, but it's not that obvious (e.g. _gsm48_rx_mm_serv_req_sec_cb()). So rather catch this case of NULL conn->subscr, and while at it catch NULL bts as well. Change-Id: I430dd952b2b928bea7f8360f1e01bb3cccb0a395

2017-02-08vty: remove ignored logging parametersMax9-11/+11
Since ce9fec3e896571835ac5bfd2980d6836f2b29f0d libosmocore ignores parameters to log_vty_command_* functions. Hence parameter of logging_vty_add_cmds() is ignored too. As we depend on much later libosmocore version anyway, we can simplify code somewhat by removing parameters which will be ignored anyway. Change-Id: I62f752fd88f1d8fefa563648f9864c7c31f87991

2017-02-06gsm_04_08: implement parsing of UMTS Auth responsesNeels Hofmeyr1-5/+221
Parse the longer UMTS res from the extended Auth Response Parameter IE. Parse the R99 Authentication Failure and AUTS in case of cause GSM_REJECT_SYNCH_FAILURE which indicates a SQN re-sync request. Both still end in 'not implemented' error logs, which are the places where the upcoming VLR that supports UMTS AKA will integrate.

2017-02-03gsm0408_rcv_cc: guard against NULL subscriberNeels Hofmeyr1-0/+5
Check conn->subscr against NULL. gsm0408_rcv_cc() dereferences many conn members without checking presence: the bts and lchan members may be expected to be NULL in the ongoing MSC split and 3G developments. But the conn->subscr is initially NULL, so an MS sending a CC message before something like a LU or CM Service Request will result in a segfault. Prevent that. Note: the upcoming VLR will be more restrictive on what messages are processed, this is a "backport" to the situation on current master. Change-Id: If067db7cc0dd3210d9eb1da15be6b637795a3ecf

2016-12-23sndcp: Allow empty SNDCP-XID indicationsPhilipp2-32/+47
In some rare cases the modem might send a xid indication that does not contain anything except the version number field. The sgsn ignors such SNDCP-XID indications by stripping the entire field from the response. We found a modem in the wild that started to act problematic when the empty SNDCP-XID was missing in the response. This patch changes the XID negotiation behaviour in a way that if a modem should send empty SNDCP-XID indications, the reply will also contain an empty SNDCP-XID indication. Apart from that the SNDCP-XID version number is now parsed and echoed in the response. This ensures that we always reply with the version number that the modem expects. (The version was 0 in all cases we observed so far) Change-Id: I097a770cb4907418f53e620a051ebb8cd110c5f2 Related: OS#1794
