3.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Thomas Graf <tgraf@xxxxxxx> [ 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.
