Subject: net/ip6_tunnel: fix dst leak
From: Paolo Abeni <pabeni@xxxxxxxxxx>
[ Upstream commit 206b49500df558dbc15d8836b09f6397ec5ed8bb ]
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.
