2017-02-23Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication.Neels Hofmeyr6-0/+149
Add msc_ifaces.[hc], a_iface.c, with a general msc_tx_dtap() to redirect to different interfaces depending on the actual subscriber connection. While iu_tx() is going to be functional fairly soon, the a_tx() is going to be just a dummy for some time (see comment). Add via_iface marker to gsm_subscriber_connection with enum values IFACE_A and IFACE_IU so far. Add Iu specific fields in a sub-struct: the UE connection pointer and an indicator for the Integrity Protection status on Iu (to be fully implemented in later commits). Add lac member to gsm_subscriber_connection, to allow decoupling from bts->location_area_code. The conn->lac will actually be set in iu.c in an upcoming commit ("add iucs.[hc]").

the BSC-side of the API behind gsm0808_submit_dtap() is doing this resolving again anyway. So let's avoid doing it twice, and avoid having more dependency of the MSC down into the lchan details. Conflicts: openbsc/src/libmsc/gsm_04_08.c Change-Id: I14254be68ee1a48e9f1ce968233414d86c6ba9d5
2017-02-23cosmetic: rename struct osmo_msc_data to bsc_msc_dataNeels Hofmeyr14-107/+107
With the OsmoMSC program coming up, the name osmo_msc_data becomes even more confusing than it already is. Clearly indicate it as libbsc's data of a remote MSC by prefixing with bsc_. Also, the Osmocom community has in the meantime agreed to have the osmo_ prefix only in libosmocore, to avoid naming conflicts in case things are moved there. So while renaming anyway, also drop the osmo_ prefix. Change-Id: I0dfbcb7d1a579211180f71319982820d8700afab

2017-02-23logging fixup: shorter names for LOGGING_FILTER_* and LOGGING_CTX_*Neels Hofmeyr5-26/+26
In libosmocore, my patch was merged to master a bit too soon. To accomodate the request for naming that matches the general "LOG" prefix instead of "LOGGING", a fixup was committed to libosmocore. Adjust for that.

2017-02-22logging: use central filter and ctx consts from libosmocoreNeels Hofmeyr7-55/+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 parametersMax10-12/+12
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

2017-01-31Remove dependency to autoconf-archiveMax3-0/+80
It is generally not a good idea to add more and more external dependencies unless absolutely needed. autoconf-archive is a good example of that, as we need to update all build machines, and older OpenEmbedded versions do not appear to have (the right?) autoconf-archive recipe.
