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 1.24 2001/02/28 11:15:01 laforge Exp $ IMPORTANT before iptables-1.2.1 release: X generic tcp sequence number offset support for nat helpers [HW] X prerelease make target (for applying certain p-o-m stuff) [RR] X header files in seperate directory, build all extensions, even when current kernel not patched [RR] X restore counters for individual rules (iptables / iptables-restore) [HW] - add libipulog / libiptc to DEVEL target [RR] INDEPENDENT from iptables-1.2.1 release: - netlink interface for conntrack manipulation from userspace [HW] - unified nfnetlink for queue,ulog,conntrack (and more?) (2.5 issue) - 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) - SMP locking for IRC buggy? - MARK match / target with boolean OR / AND (to use nfmark bitwise) X full tcp window tracking incompatibility with nat helpers [HW] X multiple related connections [HW] - documentation for libiptc - port conntrack to IPv6 (code reuse?) [BB] X port matches (owner, limit, multiport, owner) to IPv6 [RJ] - multicast connection tracking - conntrack / nat failover [HW] - Hard lockup with ip_queue under heavy load - mangle table should use all five netfilter hooks - make patch-o-matic more generic (any subdir), and reversible - CONFIG_NF_IP_NAT_LOCAL - fix and test the netfilter bridging stuff - integrate the ipt_NETLINK target from gianni@ecsc.co.uk 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 fto [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) ====================================================================== [RR] Paul 'Rusty' Russel [MB] Marc Boucher [JM] James Morris [HW] Harald Welte [YU] Yon Uriarte [RJ] Jan Rekorajski [BB] Bastian Blank
