o Create directory sys/netpfil, where all packet filters should
reside, and move there ipfw(4) and pf(4). o Move most modified parts of pf out of contrib. Actual movements: sys/contrib/pf/net/*.c -> sys/netpfil/pf/ sys/contrib/pf/net/*.h -> sys/net/ contrib/pf/pfctl/*.c -> sbin/pfctl contrib/pf/pfctl/*.h -> sbin/pfctl contrib/pf/pfctl/pfctl.8 -> sbin/pfctl contrib/pf/pfctl/*.4 -> share/man/man4 contrib/pf/pfctl/*.5 -> share/man/man5 sys/netinet/ipfw -> sys/netpfil/ipfw The arguable movement is pf/net/*.h -> sys/net. There are future plans to refactor pf includes, so I decided not to break things twice. Not modified bits of pf left in contrib: authpf, ftp-proxy, tftp-proxy, pflogd. The ipfw(4) movement is planned to be merged to stable/9, to make head and stable match. Discussed with: bz, luigi
