gro: Re-fix different skb headrooms
The patch: "gro: fix different skb headrooms" in its part: "2) allocate a minimal skb for head of frag_list" is buggy. The copied skb has p->data set at the ip header at the moment, and skb_gro_offset is the length of ip + tcp headers. So, after the change the length of mac header is skipped. Later skb_set_mac_header() sets it into the NET_SKB_PAD area (if it's long enough) and ip header is misaligned at NET_SKB_PAD + NET_IP_ALIGN offset. There is no reason to assume the original skb was wrongly allocated, so let's copy it as it was. bugzilla : https://bugzilla.kernel.org/show_bug.cgi?id=16626 fixes commit: 3d3be4333fdf6faa080947b331a6a19bce1a4f57 Reported-by: Plamen Petrov <pvp-lsts@fs.uni-ruse.bg> Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> CC: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Tested-by: Plamen Petrov <pvp-lsts@fs.uni-ruse.bg> Signed-off-by: David S.
