From fd778461524849afd035679030ae8e8873c72b81 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Tue, 3 Jan 2012 12:25:16 -0500 Subject: security: remove the security_netlink_recv hook as it is equivalent to capable() Once upon a time netlink was not sync and we had to get the effective capabilities from the skb that was being received. Today we instead get the capabilities from the current task. This has rendered the entire purpose of the hook moot as it is now functionally equivalent to the capable() call.
