2016-04-29	Start to use struct osmo_auth_vector from gsm_auth_tuple	Harald Welte	1	-3/+3
	Rather than having a 'private' structure for kc, sres and rand, we now finally (with 4 years delay) use osmo_auth_vector from libosmogsm, which encapsulates authentication vectors that can be either GSM triplets or UMTS quintuples or a combination of both. gsm_auth_tuple becomes a wrapper around osmo_auth_vector, adding use_count and key_seq to it. key_seq is no longer initialized inside gprs_gsup_messages.c, as there is no CKSN / key_seq inside the message anyway. If a usre of the code needs key_seq, they need to manage it themselves.
2016-03-31	Fix MM Auth: zero-initialize auth tuple before first use	Neels Hofmeyr	2	-1/+27
	Make sure a new auth tuple is initialized after db_get_lastauthtuple_for_subscr() returns an error, i.e. if no tuple is present for the subscriber yet. Before this patch, the first key_seq depended on the typically uninitialized value that was present in auth tuple's key_seq upon calling auth_get_tuple_for_subscr(). The very first key_seq used for a new subscriber will now always be 0. Before, it used to be mostly 1 ("(0 + 1) % 7"), but depended on whether the key_seq was indeed initialized with 0, actually by random.
2016-03-31	Fix MM Auth: disallow key_seq mismatch	Neels Hofmeyr	2	-0/+38
	In auth_get_tuple_for_subscr(), add missing condition to match incoming key_seq with stored key_seq, so that re-authentication is requested for mismatching key_seqs. Add test for this issue.
2016-03-31	MM Auth: introduce AUTH_ERROR constant.	Neels Hofmeyr	2	-2/+2
	Instead of using hardcoded -1 for errors, include -1 in the enum auth_action type; apply its use. In the mm_auth test, the string output changes from '(internal error)' to 'AUTH_ERROR', since now the proper enum value is used in auth_action_names[].
2016-03-31	MM Auth test: add test to re-use existing auth	Neels Hofmeyr	2	-0/+37

2016-03-31	MM Auth test: add two tests for AUTH_THEN_CIPH	Neels Hofmeyr	2	-0/+152
	Test two situations for AUTH_DO_AUTH_THEN_CIPH: - when no auth tuple is available - when the key sequence from LU is marked invalid Add convenience auth tuple comparison function using stringification.
2016-03-31	Add MM Auth test; add auth_action_str() function	Neels Hofmeyr	3	-0/+148
	Add basic MM Authentication test setup, with fake DB access and RAND_bytes(). So far implement simple tests for IO error during DB access and missing auth entry. To print the auth action during tests, add struct auth_action_names and auth_action_str() inline function in auth.[hc].
