* [NETFILTER]: ebtables: don't compute gap before checking struct typeChuck Ebbert2007-01-04
| | | | | | | | | | | | We cannot compute the gap until we know we have a 'struct ebt_entry' and not 'struct ebt_entries'. Failure to check can cause crash.

| * [NETFILTER]: bridge netfilter: deal with martians correctlyBart De Schuymer2006-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch resolves an issue where a IP DNATed packet with a martian source is forwarded while it's better to drop it. It also resolves messages complaining about ip forwarding being disabled while it's actually enabled. Thanks to lepton <ytht.net@gmail.com> for reporting this problem.

* [NETFILTER]: ulog: fix panic on SMP kernelsMark Huang2006-08-13
| | | | | | | | | | | | | | | | Fix kernel panic on various SMP machines. The culprit is a null ub->skb in ulog_send(). If ulog_timer() has already been scheduled on one CPU and is spinning on the lock, and ipt_ulog_packet() flushes the queue on another CPU by calling ulog_send() right before it exits, there will be no skbuff when ulog_timer() acquires the lock and calls ulog_send(). Cancelling the timer in ulog_send() doesn't help because it has already been scheduled and is running on the first CPU. Similar problem exists in ebt_ulog.c and nfnetlink_log.c.

* [NET]: Added GSO header verificationHerbert Xu2006-06-29
| | | | | | | | | | | | | | | | | | | | | | When GSO packets come from an untrusted source (e.g., a Xen guest domain), we need to verify the header integrity before passing it to the hardware. Since the first step in GSO is to verify the header, we can reuse that code by adding a new bit to gso_type: SKB_GSO_DODGY. Packets with this bit set can only be fed directly to devices with the corresponding bit NETIF_F_GSO_ROBUST. If the device doesn't have that bit, then the skb is fed to the GSO engine which will allow the packet to be sent to the hardware if it passes the header check. This patch changes the sg flag to a full features flag. The same method can be used to implement TSO ECN support. We simply have to mark packets with CWR set with SKB_GSO_ECN so that only hardware with a corresponding NETIF_F_TSO_ECN can accept them. The GSO engine can either fully segment the packet, or segment the first MTU and pass the rest to the hardware for further segmentation.
