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...

...but bear in mind that what the current release of libpcap, or even the top of the trunk, does now isn't all that it 
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.

Yes.
