From c7bdb545d23026b18be53289fd866d1ac07f5f8c Mon Sep 17 00:00:00 2001 From: Darrel Goeddel Date: Tue, 27 Jun 2006 13:26:11 -0700 Subject: [NETLINK]: Encapsulate eff_cap usage within security framework. This patch encapsulates the usage of eff_cap (in netlink_skb_params) within the security framework by extending security_netlink_recv to include a required capability parameter and converting all direct usage of eff_caps outside of the lsm modules to use the interface. It also updates the SELinux implementation of the security_netlink_send and security_netlink_recv hooks to take advantage of the sid in the netlink_skb_params struct. This also enables SELinux to perform auditing of netlink capability checks. Please apply, for 2.6.18 if possible.
