From 206b49500df558dbc15d8836b09f6397ec5ed8bb Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Wed, 18 Nov 2015 16:40:19 +0100 Subject: net/ip6_tunnel: fix dst leak the commit cdf3464e6c6b ("ipv6: Fix dst_entry refcnt bugs in ip6_tunnel") introduced percpu storage for ip6_tunnel dst cache, but while clearing such cache it used raw_cpu_ptr to walk the per cpu entries, so cached dst on non current cpu are not actually reset. This patch replaces raw_cpu_ptr with per_cpu_ptr, properly cleaning such storage.
