As this dereference directly follows a list_for_each_entry_rcu line, we have already taken a read barrier with respect to getting an entry from the list. This read barrier guarantees that all values read out of fa are valid. In particular, the contents of structure pointed to by fa->fa_info is initialised before fa->fa_info is actually set (see fn_trie_insert); the setting of fa->fa_info itself is further separated with a write barrier from the insertion of fa into the list. Therefore by taking a read barrier after obtaining fa from the list (which is given by list_for_each_entry_rcu), we can be sure that fa->fa_info contains a valid pointer, as well as the fact that the data pointed to by fa->fa_info is itself valid.

It has usually been blamed on foreign operating systems. However, some of those reports implicate Linux as both systems are running Linux or the TCP connection is going across the loopback interface. In fact, there really is a bug in the Linux TCP header prediction code that's been there since at least 2.1.8. This bug was tracked down with help from Dale Blount. The effect of this bug ranges from harmless "Treason uncloaked" messages to hung/aborted TCP connections. The details of the bug and fix is as follows. When snd_wnd is updated, we only update pred_flags if tcp_fast_path_check succeeds. When it fails (for example, when our rcvbuf is used up), we will leave pred_flags with an out-of-date snd_wnd value. When the out-of-date pred_flags happens to match the next incoming packet we will again hit the fast path and use the current snd_wnd which will be wrong. In the case of the treason messages, it just happens that the snd_wnd cached in pred_flags is zero while tp->snd_wnd is non-zero. Therefore when a zero-window packet comes in we incorrectly conclude that the window is non-zero. In fact if the peer continues to send us zero-window pure ACKs we will continue making the same mistake. It's only when the peer transmits a zero-window packet with data attached that we get a chance to snap out of it. This is what triggers the treason message at the next retransmit timeout.

That's a little bit _too_ much of a reminder that the driver is using an old API. Change this to printing out the message once, per kernel boot.

This doesn't work because the timer may have already fired when we acquire the write lock in neigh_changeaddr. The result is that the timer may keep firing for quite a while until the entry reaches NEIGH_FAILED. It should be setting the nud_state straight away so that if the timer has already fired it can simply exit once we relinquish the lock. In fact, this whole function is simply duplicating the logic in neigh_ifdown which in turn is already doing the right thing when it comes to deleting timers and setting nud_state. So all we have to do is take that code out and put it into a common function and make both neigh_changeaddr and neigh_ifdown call it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

The reason is that by the time it has obtained the write lock someone else (e.g., neigh_update) could have already added a new timer.

I found a double-free on an skb that could explain this though. dccp_sendmsg and dccp_write_xmit are a little confused as to what should free the packet when something goes wrong. Sometimes they both go for the ball and end up in each other's way. This patch makes dccp_write_xmit always free the packet no matter what. This makes sense since dccp_transmit_skb which in turn comes from the fact that ip_queue_xmit always frees the packet.
