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.

Parameters

[in]	request	The current subrequest.
[in]	vps	List to hunt for triplets in.
[in]	idx	To write EAP-SIM triplets to.
