From ece23711dd956cd5053c9cb03e9fe0668f9c8894 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 28 Oct 2018 10:35:12 -0700 Subject: net: Properly unlink GRO packets on overflow. Just like with normal GRO processing, we have to initialize skb->next to NULL when we unlink overflow packets from the GRO hash lists. Fixes: d4546c2509b1 ("net: Convert GRO SKB handling to list_head.") Reported-by: Oleksandr Natalenko Tested-by: Oleksandr Natalenko Signed-off-by: David S.
