Also it's not perfect like BPF VM, check: https://lkml.org/lkml/2012/3/30/384a

Presumably meaning


as the link didn't work with the final "a".

Don't know if such instruction can happen in BPF filter generated by libpcap (Guy?).

I'll give a look at that...

might do in a future release, so even if it doesn't generate them now, it might do so in the future.

If yes we should not enable in on kernels before it was fixed.
