audit: include source and destination ports to NETFILTER_PKT

Browse source

NETFILTER_PKT records show both source and destination
addresses, in addition to the associated networking protocol.
However, it lacks the ports information, which is often
valuable for troubleshooting.

This patch adds both source and destination port numbers,
'sport' and 'dport' respectively, to TCP, UDP, UDP-Lite and
SCTP-related NETFILTER_PKT records.

 $ TESTS="netfilter_pkt" make -e test &> /dev/null
 $ ausearch -i -ts recent |grep NETFILTER_PKT
 type=NETFILTER_PKT ... proto=icmp
 type=NETFILTER_PKT ... proto=ipv6-icmp
 type=NETFILTER_PKT ... proto=udp sport=46333 dport=42424
 type=NETFILTER_PKT ... proto=udp sport=35953 dport=42424
 type=NETFILTER_PKT ... proto=tcp sport=50314 dport=42424
 type=NETFILTER_PKT ... proto=tcp sport=57346 dport=42424
