[NETFILTER]: Fix recent match jiffies wrap mismatches
Around jiffies wrap time (i.e. within first 5 mins after boot), recent
match rules which contain both --seconds and --hitcount arguments
experience false matches.
This is because the last_pkts array is filled with zeros on creation, and
when comparing 'now' to 0 (+ --seconds argument), time_before_eq thinks it
has found a hit.
Below patch adds a break if the packet value is zero. This has the
unfortunate side effect of causing mismatches if a packet was received
when jiffies really was equal to zero. The odds of that happening are
slim compared to the problems caused by not adding the break however.
Plus, the author used this same method just below, so it is "good enough".

[NETFILTER]: Ignore ACKs ACKs on half open connections in TCP conntrack
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.

which we'd like to remove. But that's irrelevant to your pain, except...
One extract from the patches I'd like to send Doug and Kai for 2.6.15
or 2.6.16 is this below: since the incomplete get_user_pages path omits
to reset res, but has already released all the pages, it will result in
premature freeing of user pages, and behaviour just like you've seen.
Though I'd have thought incomplete get_user_pages was an exceptional
case, and a bit surprised you'd encounter it. Perhaps there's some
other premature freeing in the driver, and this instance has nothing
whatever to do with it.
If the problem were easily reproducible, it'd be great if you could
try this patch; but I think you've said it's not :-(

Graceful channel stop can take up to 1 frame time, so I've added
