eap_is_valid()

static bool eap_is_valid ( TALLOC_CTX *  ctx, eap_packet_raw_t **  eap_packet_p  )

static

Basic EAP packet verifications & validations.

Parameters

[in]	ctx	talloc ctx for the eap packet.
[in]	eap_packet_p	to validate.

Returns

• true the packet is valid.
• false the packet is invalid.

[in]	eap_session	representing the outer eap method.
[in]	server_cs	The virtual server to send the request to.

Returns

• UNLANG_ACTION_PUSHED_CHILD on success

• UNLANG_ACTION_FAIL on error
