	Multicast and broadcast packets can be looped from egress to ingress pre segmentation with dev_loopback_xmit. That function unconditionally sets ip_summed to CHECKSUM_UNNECESSARY. udp_rcv_segment segments gso packets in the udp rx path. Segmentation usually executes on egress, and does not expect packets of this type. __udp_gso_segment interprets !CHECKSUM_PARTIAL as CHECKSUM_NONE. But the offsets are not correct for gso_make_checksum. UDP GSO packets are of type CHECKSUM_PARTIAL, with their uh->check set to the correct pseudo header checksum. Reset ip_summed to this type. (CHECKSUM_PARTIAL is allowed on ingress, see comments in skbuff.h) Reported-by: syzbot <syzkaller@googlegroups.com> Fixes: cf329aa42b66 ("udp: cope with UDP GRO packet misdirection") Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

	The old netem mailing list was inactive and recently was targeted by spammers. Switch to just using netdev mailing list which is where all the real change happens. Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S. Miller <davem@davemloft.net>
