net: Reset secmark when scrubbing packet
[ Upstream commit b8fb4e0648a2ab3734140342002f68fb0c7d1602 ]
skb_scrub_packet() is called when a packet switches between a context
such as between underlay and overlay, between namespaces, or between
L3 subnets.
While we already scrub the packet mark, connection tracking entry,
and cached destination, the security mark/context is left intact.
It seems wrong to inherit the security context of a packet when going
from overlay to underlay or across forwarding paths.
