2007-03-24[NETFILTER]: tcp conntrack: accept SYN|URG as validPatrick McHardy

2006-08-26ulog: fix panic on SMP kernelsMark Huang
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.

Performance tests showed that ULOG may fail on heavy loaded systems because of failed order-N allocations (N >= 1). The default value of 4096 is not optimal in the sense that it actually allocates _two_ contigous physical pages. Reasoning: ULOG uses alloc_skb(), which adds another ~300 bytes for skb_shared_info.

2005-12-01[NETFILTER]: Ignore ACKs ACKs on half open connections in TCP conntrackJozsef Kadlecsik
Mounting NFS file systems after a (warm) reboot could take a long time if firewalling and connection tracking was enabled. The reason is that the NFS clients tends to use the same ports (800 and counting down). Now on reboot, the server would still have a TCB for an existing TCP connection client:800 -> server:2049. The client sends a SYN from port 800 to server:2049, which elicits an ACK from the server. The firewall on the client drops the ACK because (from its point of view) the connection is still in half-open state, and it expects to see a SYNACK. The client will eventually time out after several minutes. The following patch corrects this, by accepting ACKs on half open connections as well.
