[tcpdump-workers] Modular arithmetic
I don't see any discussion regarding adding modular operations to pcap, i.e. "header[offset:width] % 4 != 0". I've put together a patch that compiles & honors that (at least on the few systems I've tried), but was wondering if there were any fundamental reason to avoid it? Thanks. g ___ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers

Did I miss that this is a tcpdump change, not a pcap one :-( David ___ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
