◆ fr_aka_sim_umts_resync_from_attrs()

int fr_aka_sim_umts_resync_from_attrs	(	uint64_t *	new_sqn,
		request_t *	request,
		fr_pair_t *	auts_vp,
		fr_aka_sim_keys_t *	keys
	)

Perform milenage AUTS validation and resynchronisation.

Parameters

[out]	new_sqn	The new sequence number provided by the AUTS.
[in]	request	The current request.
[in]	auts_vp	The AUTS response.
[in]	keys	UMTS keys.

Returns

1 if we do not have sufficient data (lacking ki).
0 on success.
-1 on validation failure.
