Subject[PATCH net v1 0/2] net: gro: add flush/flush_id checks and fix wrong offset in udp
Date
This series fixes a bug in the complete phase of UDP in GRO, in which
socket lookup fails due to using network_header when parsing encapsulated
packets. The fix is to pass p_off (previous offset, offset to the start of
the previous layer) parameter in *_gro_complete.

The original series includes a change to a vxlan test which adds the local
parameter to prevent similar future bugs. I plan to submit it separately
to net-next.

In addition p->flush/flush_id should be checked in relevant UDP flows. Same
logic from tcp_gro_receive is applied for the relevant flows in
udp_gro_receive_segment.

This series is part of a previously submitted series to net-next:
