Comment 1 Serguei Makarov 2012-05-23 13:41:29 UTC 
Yes, this is a known bug, which is why there's a test for it. There's some kind of extremely subtle issue with how derived probes are named.
Comment 2 Serguei Makarov 2012-05-23 13:46:46 UTC 
Yes, this is a known bug, which is why there's a test for it. There's some kind of extremely subtle issue with how derived probes are named. It is probably possible to bypass it with a complicated solution (such as defining a special tick counter for naming the netfilter hook functions). However, something like that will only be a last resort if for some reason we can't get the simple solution to work...
