Because the "timeout" as set by setsockopt() is converted into number
of retransmits.
> We receive a pure ACK (wihout DATA).

No, we will receive other ones because the socket remains in SYN_RECV
and since the local system ignores this ACK, it will send a SYN-ACK
again, triggering a new ACK from the client.
Although the concept looks strange at first, I think its implementation
is in fact very smart because it manages to defer acceptation with an
approximate timeout without using another timer.
The most common requirement should only be to wait for an HTTP request
to come in, and setting the timeout to anything non-zero is enough to
just drop the first empty ACK and immediately accept on the data
segment, so this method fits this purpose perfectly.

Willy

Why does it ignore the ACK? Just because that's the simplest
implementation of defer_accept?

Indeed, thanks for this detailed explanation, I missed the SYN-ACK timer
and retransmits.
I played some years ago with TCP_DEFER_ACCEPT and got some unexpected results
on transmitted packets (server was consuming more bandwidth), and I know understand
it was very broken until today !

And here it is another one, this time triggered by postfix, where mor
drbd nor vserver are involved.
This is not the same server where the other oopses were grabbed.

Actually i found another oops which is very similar to the previous one.
Here, vserver is not involved, and the problem starts at drbd which
lives in kernel space (the other oops started at ocfs2).
Both ocfs2 and drbd make heavy use of network I/O so i guess the problem
is something in the network layer.
Anything i can do to help to debugging and solving this issue ?
Thanks
Max

Hi Craig
This particular problem should/could be fixed in 2.6.31.4 by commit
d99927f4d93f36553699573b279e0ff98ad7dea6
(net: Fix sock_wfree() race)
Please try to reproduce your tickless problem on 2.6.31.4 or latest Linus git tree
Thanks

Problem is kfree_skb() is called from irq context, wich is not allowed.
static void skb_release_head_state(struct sk_buff *skb)
{
...
if (skb->destructor) {
WARN_ON(in_irq());
skb->destructor();
}
...
}
virtio_net start_xmit() function calls free_old_xmit_skbs() and
free_old_xmit_skbs() ultimately calls kfree_skb()
Quick fix would be to use dev_kfree_skb_any() instead,
because netpoll can definitly calls start_xmit()
with irq disabled.
Could you please following patch ?

Is all of your traffic going over virtio_net?

Indeed, because of netpoll(), that is something drivers
must be able to cope with.

Indeed, let us know how Eric's patch works.
Thanks Eric!

Thank you very much.
Compiling.
It' will be in production in a few minutes.
I'll let you know if the problem arises again.
give me a couple of days because this problem is randomly triggered.
Sometimes it happens multiple times a day, sometimes none.

The more I think about the less this makes sense.
There is no way to setup these semantics of lower level
routes and satisfy every reasonable use case.
We'll need to provide another facility or suggest other
methods to control marking of encapsulated routes from
the socket level, sorry.

Yes, it's crummy how things work now, indeed.

It should be.
I've applied your patch, thanks!
