It would be good to have some general purpose coprocessor (for walking IPv6 header chain and other operations), but that would probably be difficult to agree and standardise amongst the vendors.Which speaks to BPF needing new instructions or a new instruction set that can handle those tasks.
Many many years ago I already suggested the limited-duration "LOOP" instruction as a means to handle IPv6 chains in a way that doesn't lead to deadlocks/etc by having a generic loop ability. https://lists.freebsd.org/pipermail/freebsd-hackers/2013-October/043602.html If you want to support 'v6 better, maybe take a look at that? -- Paul "LeoNerd" Evans leonerd () leonerd org uk http://www.leonerd.org.uk/ | https://metacpan.org/author/PEVANS _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
