Does it happen when you unload only nf_conntrack_ipv4, or do you need to unload other modules previously? Does it really lock up?

I can't tell which module it stopped on because that computer is at home today. And yes, it really locks up until it's caught by the softlockup watchdog. Has only happened on a uniprocessor i686 system so far, but happens every time on shutdown. > Please also send your config. Standard Fedora 6 i686 config, updated for 2.6.20, not released yet. I'll attach it.

[-- Attachment #2: x --] [-- Type: text/plain, Size: 11995 bytes --] [NETFILTER]: conntrack: fix {nf,ip}_ct_iterate_cleanup endless loops {nf,ip}_ct_iterate_cleanup iterate over the unconfirmed list for cleaning up conntrack entries, which is wrong for multiple reasons: - unconfirmed entries can not be killed manually, which means we might iterate forever without making forward progress. This can happen in combination with the conntrack event cache, which holds a reference to the conntrack entry, which is only released when the packet makes it all the way through the stack or a different packet is handled. - taking references to an unconfirmed entry and using it outside the locked section doesn't work, the list entries are not refcounted and another CPU might already be waiting to destroy the entry Split ip_ct_iterate_cleanup in ip_ct_iterate, which iterates over both confirmed and unconfirmed entries, but doesn't attempt to kill them, and ip_ct_cleanup, which makes sure no unconfirmed entries exist by calling synchronize_net() prior to walking the conntrack hash.

What about this case: 1. Conntrack entry is created and placed on the unconfirmed list 2. The event cache bumps the refcount of the conntrack entry 3. module removal of ip_conntrack unregisters all hooks 4. packet is dropped by an iptables rule 5. packet is freed but we still have a refcount on the conntrack entry Now there's no way to get that refcount to decrease as that only happens when the event cache receives another packet or the current packet makes it through the stack as you wrote above. And neither of this will happen since we unregistered the hooks providing the packets and dropped the packet. I ran into this case a while ago during stresstesting and rewrote the event cache to not increase the refcount, but this has the drawback that events caused by dropped packets won't be reported. This may not be a good thing...

The event cache is flushed on conntrack module unload after the hooks have been unregistered, which should release all references. ^ permalink raw reply [flat|nested] 12+ messages in thread

This patch takes a simpler approach and keeps the unconfirmed list iteration, but makes sure to make forward progress. [-- Attachment #2: x --] [-- Type: text/plain, Size: 3702 bytes --] [NETFILTER]: conntrack: fix {nf,ip}_ct_iterate_cleanup endless loops Fix {nf,ip}_ct_iterate_cleanup unconfirmed list handling: - unconfirmed entries can not be killed manually, they are removed on confirmation or final destruction of the conntrack entry, which means we might iterate forever without making forward progress. This can happen in combination with the conntrack event cache, which holds a reference to the conntrack entry, which is only released when the packet makes it all the way through the stack or a different packet is handled. - taking references to an unconfirmed entry and using it outside the locked section doesn't work, the list entries are not refcounted and another CPU might already be waiting to destroy the entry What the code really wants to do is make sure the references of the hash table to the selected conntrack entries are released, so they will be destroyed once all references from skbs and the event cache are dropped. Since unconfirmed entries haven't even entered the hash yet, simply mark them as dying and skip confirmation based on that.
