Not sure if skb_trim needs fixing, or IP is broken.. Should be fixed by: e9fa4f7bd291c29a785666e2fa5a9cf3241ee6c3 [INET]: Use pskb_trim_unique when trimming paged unique skbs The IPv4/IPv6 datagram output path was using skb_trim to trim paged packets because they know that the packet has not been cloned yet (since the packet hasn't been given to anything else in the system). This broke because skb_trim no longer allows paged packets to be trimmed. Paged packets must be given to one of the pskb_trim functions instead. This patch adds a new pskb_trim_unique function to cover the IPv4/IPv6 datagram output path scenario and replaces the corresponding skb_trim calls with it.
