Dear colleagues, [all below is for 4-STABLE]
I'm trying to write effective arp scanner for multi-interface router (esp. multi-vlan); I plan to use multiple bpf devices attached to different interfaces emitting ARP requests and filters listening to ARP replies; the most natural way to multiplex them for me is select(). However, my tests show that select()ing bpf fd does not lead to trigger packets available to bpf filter; the process hangs in select state while parallel tcpdump process shows packets desired *and* is in bpf state. Am I missing something "base"? References (surely, I'd already read manpages for bpf, pcap and related -- but did I still missed something serious?) would be greatly appreciated. Thanks for your time, as always.
