audit: Use current instead of NETLINK_CREDS() in audit_filter
Get caller process uid and gid and pid values from the current task instead of the NETLINK_CB. This is simpler than passing NETLINK_CREDS from from audit_receive_msg to audit_filter_user_rules and avoid the chance of being hit by the occassional bugs in netlink uid/gid credential passing. This is a safe changes because all netlink requests are processed in the task of the sending process. Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Eric Paris <eparis@redhat.com> Signed-off-by: "Eric W.
