Provides support for a new field ipaddr within the SELinux AVC audit log, relying in task_struct->curr_ip (ipv4 only) provided by the task-curr_ip or grSecurity patch to be applied before.It was first implemented by Joshua Brindle (a.k.a Method) from the Hardened Gentoo project.
An example of the audit messages with ipaddr field: audit(1110432234.161:0): avc: denied { search } for pid=19057 exe=/usr/bin/wget name=portage dev=hda3 ino=1024647 ipaddr=192.168.1.30 scontext=root:sysadm_r:portage_fetch_t tcontext=system_u:object_r:portage_tmp_t tclass=dir
