Perf traces of network-related workload shows a measurable overhead inside the network-related selinux hooks while zeroing the lsm_network_audit struct. In most cases we can delay the initialization of such structure to the usage point, avoiding such overhead in a few cases. Additionally, the audit code accesses the IP address information only for AF_INET* families, and selinux_parse_skb() will fill-out the relevant fields in such cases. When the family field is zeroed or the initialization is followed by the mentioned parsing, the zeroing can be limited to the sk, family and netif fields. By factoring out the audit-data initialization to new helpers, this patch removes some duplicate code and gives small but measurable performance gain under UDP flood.
