TODO List for netfilter / iptables. Currently maintained by Harald Welte Please inform me, if you want to work on any of the TODO items, so I can update this list and thus prevent two people doing the same work. CVS ID: $Id: TODO,v 1.29 2001/04/24 00:02:33 laforge Exp $ IMPORTANT issues: - solution for nostate / notrack (we don't want to track specific conn's) - multiple related connections [HW] - ip_conntrack rmmod loop (sometimes, Yan's patch?) - conntrack helper not called for first packet (udp!) - why is nat_helper's expect() function called for all helpers? X full tcp window tracking incompatibility with nat helpers [HW] ? Hard lockup with ip_queue under heavy load (was possibly some unrelated 2.3 problem) [JM] - mangle table should use all five netfilter hooks [HW] - merge EPRT / EPSV ftp stuff X runme error with IPv6 stuff! [HW] - wrong 'Out of window' error message from tcp-windowtracking [HW] - SMP conntrack race [RR] NICE to have: - multicast connection tracking - sysctl support for ftp-multi, irc-conntrack/nat, ftp-fxp - integrate HOPLIMIT for ipv6 in patch-o-matic [HW] - static 1:1 NAT (only ip address NAT in both directions) - u32 classifier (port from tc -> iptables) [YU] - pktlen match (not needed, when u32 available) - MARK match / target with boolean OR / AND (to use nfmark bitwise) - documentation for libiptc - port conntrack to IPv6 (code reuse?) [BB] X port matches (owner, limit, multiport, owner) to IPv6 [RJ] - make patch-o-matic more generic (any subdir), and reversible - CONFIG_NF_IP_NAT_LOCAL - fix and test the netfilter bridging stuff X integrate the ipt_NETLINK target from gianni@ecsc.co.uk [HW] X integrate PSD target / port it as match [HW] - various NAT performance optimizations possible! (which? ask HW) - ip_nat_ident module - provide daily CVS snapshots via ftp [HW] - 10.1.2.3.4 is accepted as a valid IP address by iptables -s / -d ? - make iptables / ip6tables use the same codebase (as libiptc) FUTURE extensions: - conntrack / nat failover [HW] - brainstorming about 2.5 conntrack code - netlink interface for conntrack manipulation from userspace [HW] - unified nfnetlink for queue,ulog,conntrack (and more?)
