From c243d7e20996254f89c28d4838b5feca735c030d Mon Sep 17 00:00:00 2001 From: Ying Xue Date: Mon, 16 Mar 2015 18:19:12 +0800 Subject: [PATCH] net: kernel socket should be released in init_net namespace Creating a kernel socket with sock_create_kern() happens in "init_net" namespace, however, releasing it with sk_release_kernel() occurs in the current namespace which may be different with "init_net" namespace. Therefore, we should guarantee that the namespace in which a kernel socket is created is same as the socket is created. Signed-off-by: Ying Xue Signed-off-by: David S.
