| |
Hi all, I wanted to bring up an issue with ip_conntrack in 2.4.23, 2.4.22, and at least 2.4.21 (sorry, didn't try 2.4.20).
The issue is that as long as there are connections being tracked, the ip_conntrack module will not unload. I can understand why this might be, but the problem is that ip_conntrack will hang rmmod and modprobe -r until such time as all the connections have been closed.
I think we need something like an ip_conntrack_flush or else completely drop the connections when the module is unloaded (as previously done) as this becomes an issue for people who need to drop their ip_tables and reload the modules (perhaps to correct other issues) especially ip_conntrack...
The only way to reload the modules right now (yes, I know removing modules from a running kernel is dodgey anyway) is to completely drop the network interfaces which kills off the connections *anyway*. So, dropping the connections shouldn't be an issue.
Thanks for the consideration.
Regards James
