Subject: [PATCH 0/6] audit: add restricted capability read-only netlink multicast socket

From: Richard Guy Briggs <rgb@...hat.com>

Hi,

This is a patch set Eric Paris and I have been working on to add a restricted
capability read-only netlink multicast socket to kaudit to enable 
userspace clients such as systemd to consume audit logs, in addition to the
bidirectional auditd userspace client.

Currently, auditd has the CAP_AUDIT_CONTROL and CAP_AUDIT_WRITE capabilities
(bot uses CAP_NET_ADMIN).  The CAP_AUDIT_READ capability will be added for use
by read-only AUDIT_NLGRP_READLOG multicast group clients to the kaudit
subsystem.

https://bugzilla.redhat.com/show_bug.cgi?id=887992

Feedback please!

Richard Guy Briggs (6):
  audit: refactor hold queue flush
  audit: flatten kauditd_thread wait queue code
  audit: move kaudit thread start from auditd registration to kaudit
    init
  netlink: add send and receive capability requirement and capability
    flags
  audit: add the first netlink multicast socket group
  audit: send multicast messages only if there are listeners
