netfilter: audit target to record accepted/dropped packets
This patch adds a new netfilter target which creates audit records
for packets traversing a certain chain.
It can be used to record packets which are rejected administraively
as follows:
-N AUDIT_DROP
-A AUDIT_DROP -j AUDIT --type DROP
-A AUDIT_DROP -j DROP
a rule which would typically drop or reject a packet would then
invoke the new chain to record packets before dropping them.
-j AUDIT_DROP
The module is protocol independant and works for iptables, ip6tables
and ebtables.
The following information is logged:
- netfilter hook
- packet length
- incomming/outgoing interface
- MAC src/dst/proto for ethernet packets
- src/dst/protocol address for IPv4/IPv6
- src/dst port for TCP/UDP/UDPLITE
- icmp type/code
