| TODO List for netfilter / iptables. |
| Currently maintained by Harald Welte <laforge@gnumonks.org> |
| |
| 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. |

| IMPORTANT issues: |
| - erroneously too-fast dropped conntrack for half-open TCP connections [JK] |
| X wrong 'Out of window' error message from tcp-windowtracking [JK] |
| - --mac-source not working in FORWARD (manpage bug?) [BZ] |
| X update manpages to include recently submitted extensions [BZ] |
| - locally bound udp port can still be used for MASQ/SNAT [BZ] |
| X fix for ICMP DNAT info leak |
| - unaligned access of nulldevname during string match [BZ] |
| - update documentation to reflect newnat |
| - ip6_tables not working on ultrasparc [BZ] |
| (20020912155314.GA20741@paradigm.rfc822.org) |
| |
| TO BE INVESTIGATED: |
| - packet counters on sparc64 platform [BZ] |
| - ip_conntrack rmmod loop (sometimes, Yan's patch?) |
| - conntrack helper not called for first packet (udp!) |
| - different behaviour for first packet towards an l2-unresolved ip? |
| |
| NICE to have: |
| - endianness wrt. unnamed initializers in conntrack helpers after |
| pptp-patch applied |
| X make RPC conntrack work again |
| - multicast connection tracking |
| - sysctl support for ftp-multi, irc-conntrack/nat, ftp-fxp [BZ] |
| X integrate HOPLIMIT for ipv6 in patch-o-matic [HW] |
| X u32 classifier (port from tc -> iptables) [YU] |
| - port conntrack to IPv6 (code reuse?) [BC] |
| - ip_nat_ident module [BZ] |
| - make iptables / ip6tables use the same codebase (as libiptc) [KA] |
| - libipq reentrancy [JM] |
| - compiling without O2 issue [BZ] |
| - libipq runtime version, do before 1.2.5 [JM] |
| - add ICMP type-3-code-13 option to REJECT [BZ] |
| X export list of matches/targets via proc-fs [BZ] |
| X ip6tables mangle needs 'route_me_harder' equivalent [BZ] |
| |
| FUTURE extensions: |
| - dealing with fragmented expectation-causes (i.e. DCC chat split |
| over two packets, etc.) |
| - 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?) (2.5 issue) |
| |
| Userspace queuing for 2.5: |
| - Integration with nfnetlink. |
| - Multiple queues per protocol. |
| - Netlink broadcast support. |
| - Allow multiple reader/writers in userspace. |
| - How to handle multiple protocols (e.g. use separate queue handlers |
| or a multiplexer like ipqmpd). |
| - Peformance improvements: multipart messages, mmaped socket (possibly). |
| - Simplify queuing logic, which is quite ugly at the moment. (BC suggested |
| removing logic from kernel). |
| - Allow userspace to set nfmark. |
| - Allow userspace to set queue length etc. |
| - Possibly pass conntrack/NAT info to userspace with packet. |
