2017-03-09	vlr: fix: don't send CM Service Accept after Ciphering Command	Neels Hofmeyr	1	-1/+4
	Ciphering Mode Command is an implicit CM Service Accept, if we're sending both we're confusing the MS. Change-Id: I3a04debe9b01c086e7f44b6139cb8796fcc71d38 Conflicts: openbsc/tests/msc_vlr/msc_vlr_test_umts_authen.c openbsc/tests/msc_vlr/msc_vlr_test_umts_authen.err
2017-03-09	fix: vlr: clear last_tuple when receiving auth tuples	Neels Hofmeyr	1	-0/+3
	When receiving more than one auth tuple during AUTS resync, the VLR would go on to send the second tuple instead of the first. The unit test didn't catch that because its fake HLR message contained only one tuple. Adjust the test to send two tuples to catch this error. Fix the code to clear vlr_subscr->last_tuple whenever new auth tuples are received. Change-Id: I1f84e7d2619aa8d9a0dcdfb50745feeb040264b9
2017-03-09	gsup_client: allow passing a unit id to identify with HLR	Neels Hofmeyr	1	-3/+4
	Before, each GSUP client would contact the HLR with an identical unit id, i.e. "SGSN-00-00-00-00-00-00", with the result that some messages were sucked off by the wrong client. Pass explicit unit name from each gsup client user, so that OsmoMSC is "MSC" and OsmoSGSN is "SGSN". Hence the HLR can properly route the messages. Todo: also set some values instead of the zeros.

2017-03-09	vlr: get SMS working, by SMS recipient MSISDN round-robin	Neels Hofmeyr	1	-0/+4
	The SQL based lookup of SMS for attached subscribers no longer works since the SQL database no longer has the subscriber data. Replace with a round-robin on the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the subscriber is currently attached. If there are many SMS for not-attached subscribers in the SMS database, this will become inefficient: a DB hit returns a pending SMS, the RAM lookup will reveal that the subscriber is not attached, after which the DB is hit for the next SMS. It would become more efficient e.g. by having an MSISDN based hash list for the VLR subscribers and by marking non-attached SMS recipients in the SMS database so that they can be excluded with the SQL query already. There is a sanity limit to do at most 100 db hits per attempt to find a pending SMS. So if there are more than 100 stored SMS waiting for their recipients to actually attach to the MSC, it may take more than one SMS queue trigger to deliver SMS for subscribers that are actually attached. This is not very beautiful, but is merely intended to carry us over to a time when we have a proper separate SMSC entity. Change-Id: I1acf9debb6ba9164e6edcfd5bc5e48e8c98f2b01

2017-03-09	Use libvlr in libmsc (large refactoring)	Neels Hofmeyr	1	-0/+1
	Original libvlr code is by Harald Welte <laforge@gnumonks.org>, polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>. This is a long series of development collapsed in one patch. The original history may still be available as branch neels/vlr_orig. TODO: This commit may be split in several smaller changes before merging to master.
