Subject: [patch 1/1] SELinux AVC audit log ipaddr field support (for task_struct->curr_ip)
Date: Thu, 10 Mar 2005 16:05:40 +0100 [thread overview]
Message-ID: <1110467140.9190.9.camel@localhost.localdomain> (raw)
[-- Attachment #1: Type: text/plain, Size: 1702 bytes --]
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
It's also available at http://pearls.tuxedo-es.org/patches/selinux-avc_audit-log-curr_ip.patch
