-Subject: [PATCH] cgroup: fix cgroup_sk_alloc() for sk_clone_lock()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-When we clone a socket in sk_clone_lock(), its sk_cgrp_data is
-copied, so the cgroup refcnt must be taken too. And, unlike the
-sk_alloc() path, sock_update_netprioidx() is not called here.
-Therefore, it is safe and necessary to grab the cgroup refcnt
-even when cgroup_sk_alloc is disabled.
-
-sk_clone_lock() is in BH context anyway, the in_interrupt()
-would terminate this function if called there. And for sk_alloc()
-skcd->val is always zero. So it's safe to factor out the code
-to make it more readable.
-
-Fixes: 090e28b229af92dc5b ("netprio_cgroup: Fix unlimited memory leak of v2 cgroups")
