Currently, NETFILTER_PKT records lack source and destination
port information, which is often valuable for troubleshooting.
This patch series adds ports numbers, to NETFILTER_PKT records.

The first patch refactors netfilter-related code, by moving
duplicated code to audit.c, creating two helper functions:
'audit_log_packet_ip4' and 'audit_log_packet_ip6'.
The second one, improves the NETFILTER_PKT records, by
including source and destination ports for protocols of
interest.

Ricardo Robaina (2):
audit: add audit_log_packet_ip4 and audit_log_packet_ip6 helper
functions
audit: include source and destination ports to NETFILTER_PKT
