[PATCH net 0/2] net: bridge: vlan tunnel egress path fixes

[Nikolay Aleksandrov <razor@xxxxxxxxxxxxx>]

From: Nikolay Aleksandrov <nikolay@xxxxxxxxxx>

Hi,
These two fixes take care of tunnel_dst problems in the vlan tunnel egress
path. Patch 01 fixes a null ptr deref due to the lockless use of tunnel_dst
pointer without checking it first, and patch 02 fixes a use-after-free
issue due to wrong dst refcounting (dst_clone() -> dst_hold_safe()).

Both fix the same commit and should be queued for stable backports:
11538d039ac6 ("bridge: vlan dst_metadata hooks in ingress and egress paths")

Thanks,
 Nik
