[XFRM]: RFC4303 compliant auditing
This patch adds a number of new IPsec audit events to meet the auditing requirements of RFC4303. This includes audit hooks for the following events: * Could not find a valid SA [sections 2.1, 3.4.2] . xfrm_audit_state_notfound() . xfrm_audit_state_notfound_simple() * Sequence number overflow [section 3.3.3] . xfrm_audit_state_replay_overflow() * Replayed packet [section 3.4.3] . xfrm_audit_state_replay() * Integrity check failure [sections 3.4.4.1, 3.4.4.2] . xfrm_audit_state_icvfail() While RFC4304 deals only with ESP most of the changes in this patch apply to IPsec in general, i.e. both AH and ESP. The one case, integrity check failure, where ESP specific code had to be modified the same was done to the AH code for the sake of consistency.
