Eric Dumazet 817c7cd204 gve: fix frag_list chaining ... gve_rx_append_frags() is able to build skbs chained with frag_list, like GRO engine. Problem is that shinfo->frag_list should only be used for the head of the chain. All other links should use skb->next pointer. Otherwise, built skbs are not valid and can cause crashes. Equivalent code in GRO (skb_gro_receive()) is: if (NAPI_GRO_CB(p)->last == p) skb_shinfo(p)->frag_list = skb; else NAPI_GRO_CB(p)->last->next = skb; NAPI_GRO_CB(p)->last = skb; Fixes: 9b8dd5e5ea ("gve: DQO: Add RX path") Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Bailey Forrest <bcf@google.com> Cc: Willem de Bruijn <willemb@google.com> Cc: Catherine Sullivan <csully@google.com> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: David S.
