This patch series adds ports numbers, to NETFILTER_PKT records. The first patch refactors netfilter-related code, by moving duplicated code to audit.c, by creating audit_log_nf_skb() helper function. The second one, improves the NETFILTER_PKT records, by including source and destination ports for protocols of interest.
