[XFRM]: Assorted IPsec fixups
This patch fixes a number of small but potentially troublesome things in the XFRM/IPsec code: * Use the 'audit_enabled' variable already in include/linux/audit.h Removed the need for extern declarations local to each XFRM audit fuction * Convert 'sid' to 'secid' everywhere we can The 'sid' name is specific to SELinux, 'secid' is the common naming convention used by the kernel when refering to tokenized LSM labels, unfortunately we have to leave 'ctx_sid' in 'struct xfrm_sec_ctx' otherwise we risk breaking userspace * Convert address display to use standard NIP* macros Similar to what was recently done with the SPD audit code, this also also includes the removal of some unnecessary memcpy() calls * Move common code to xfrm_audit_common_stateinfo() Code consolidation from the "less is more" book on software development * Proper spacing around commas in function arguments Minor style tweak since I was already touching the code Signed-off-by: Paul Moore <paul.moore@hp.com> Acked-by: James Morris <jmorris@namei.org> Signed-off-by: David S. Miller <davem@davemloft.net>
