David, what's the right way to fix that ?

There is no doubt that sock_fprog is the correct datastructure to use.

Ok, so the right fix is to email anybody who posted code using struct
bpf_program to fix their code ? :-)

Actually, the right fix is for anybody using pcap-bpf.h to not
use SO_ATTACH_FILTER directly but to use pcap_setfilter() which
handles the compatibility.

I'll start spamming web sites who tell people to do the wrong thing.

Cheers,
Ben.
