If it is - this is a bug in ISN generation algo and must be fixed. It is the same situation, which would happen if you will spam remote side with RST packets with arbitrary sequence number in hope that it will reset some connection. Isn't it still possible that the connection that got reset is left open (possibly for days) until another connection using the same ports is using roughly the same sequence numbers?

Slow block devices can produce surprising effects. Ddsnap still qualifies as slow under certain circumstances (big linear write immediately following a new snapshot). Before we added throttling we would see as many as 800,000 bios in flight. Nice to Mmm, sounds tasty to work with such a system :) know the system can actually survive this... mostly. But memory deadlock is a clear and present danger under those conditions and we did hit it (not to mention that read latency sucked beyond belief). Anyway, we added a simple counting semaphore to throttle the bio traffic to a reasonable number and behavior became much nicer, but most importantly, this satisfies one of the primary requirements for avoiding block device memory deadlock: a strictly bounded amount of bio traffic in flight. In fact, we allow some bounded number of non-memalloc bios *plus* however much traffic the mm wants to throw at us in memalloc mode, on the assumption that the mm knows what it is doing and imposes its own bound of in flight bios per device. This needs auditing obviously, but the mm either does that or is buggy. In practice, with this throttling in place we never saw more than 2,000 in flight no matter how hard we hit it, which is about the number we were aiming at. Since we draw our reserve from the main memalloc pool, we can easily handle 2,000 bios in flight, even under extreme conditions. See: http://zumastor.googlecode.com/svn/trunk/ddsnap/kernel/dm-ddsnap.c down(info-throttle_sem); To be sure, I am not very proud of this throttling mechanism for various reasons, but the thing is, _any_ throttling mechanism no matter how sucky solves the deadlock problem. Over time I want to move the make_request_fn is always called in process context, we can wait in it for memory in mempool. Although that means we already in trouble. I agree, any kind of high-boundary leveling must be implemented in device itself, since block layer does not know what device is at the end and what it will need to process given block request. -- Evgeniy Polyakov - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

I meant to create a storage on top of several nodes one needs to have device mapper or something like that on top of NBD itself. To further export resulted device one needs another userspace NDB application and so on. DST simplifies that greatly. DST original code worked as device mapper plugin too, but its two additional allocations (io and clone) per block request ended up for me as a show stopper. -- Evgeniy Polyakov - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Autobinding during first sending can end up being a protection against DoS in some obscure rare case... accept()ed socket is by definition fully bound and already in established state.

I took a look at this, and it's not %100 trivial. Let's do this later, and only sendmsg for now in order to fix the bug in the stable branches. I've tested your patch, besides there was an offset in one of hooks, it works perfectly ok. Feel free to add my ack, tested-by or whatever is needed for this :) Your patch fixes the problem. It is already merged to Linus's tree long before you found a chance to test it :-) So it would be difficult for me to do so. - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
