From a4c9a56e6a2cdeeab7caef1f496b7bfefd95b50e Mon Sep 17 00:00:00 2001 From: Anjali Kulkarni Date: Wed, 19 Jul 2023 13:18:17 -0700 Subject: netlink: Add new netlink_release function A new function netlink_release is added in netlink_sock to store the protocol's release function. This is called when the socket is deleted. This can be supplied by the protocol via the release function in netlink_kernel_cfg. This is being added for the NETLINK_CONNECTOR protocol, so it can free it's data when socket is deleted. Signed-off-by: Anjali Kulkarni Reviewed-by: Liam R.
