[Devel] [PATCH hci-8.1 1/1] udp: let rx-udp-gro-forwarding aggregate under encapsulation

[no-reply at sashiko.virtuozzo.com]

> The rx-udp-gro-forwarding checks of the veth selftest fail with "got
> 10 packets, expected 1" on a host where something uses UDP encap,
> for example a vxlan, and pass on a host where nothing does.
> 
> Since commit f2e9de210d50 ("udp: gro behind static key") the receiving
> socket is looked up only once a tunnel socket exists, and commit
> 36707061d6ba ("udp: allow forwarding of plain (non-fraglisted) UDP GRO
> packets") takes "no socket found" for "forwarded" and aggregates only
> then. So the device setting works on a host without a tunnel and stops
> working with one.
> 
> Aggregate whenever the device asks, socket found or not. That is what
> every host without a tunnel has done all along: a local socket without
> UDP_GRO gets the packets resegmented on delivery, and a tunnel socket
> keeps its own receive path.
