When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of the packet, the frag_list is not updated to reflect the trimming. This will usually work fine until you hit something that uses the packet length or tail from the frag_list. Examples include esp_output and ip_fragment. Another problem caused by this is that you can end up with a linear packet with a frag_list attached. It is possible to get away with this if we audit everything to make sure that they always consult skb->len before going down onto frag_list. In fact we can do the samething for the paged part as well to avoid copying the data area of the skb. For now though, let's do the conservative fix and update frag_list. Many thanks to Marco Berizzi for helping me to track down this bug. This 4-year old bug took 3 months to track down. Marco was very patient indeed :) Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net> |
