From 54bb06645bcb9423b6e98622189414a1d7172428 Mon Sep 17 00:00:00 2001 From: mlaier Date: Sat, 28 Feb 2004 21:50:50 +0000 Subject: Add skeleton build dirs for pf userland: libexec/ftp-proxy - ftp proxy for pf sbin/pfctl - equivalent to sbin/ipf sbin/pflogd - deamon logging packets via if_pflog in pcap format usr.sbin/authpf - authentification shell to modify pf rulesets Bring along some altq headers used to satisfy pfctl/authpf compile. This helps to keep the diff down and will make it easy to have a altq-patchset use the full powers of pf. Also make sure that the pf headers are installed. This does not link anything to the build. There will be a NO_PF switch for make.conf once pf userland is linked.
