Harald Welte | 3666e0e | 2001-04-12 22:24:29 +0000 | [diff] [blame] | 45 | FUTURE extensions: |
Harald Welte | b961e6b | 2001-05-05 00:01:55 +0000 | [diff] [blame] | 46 | - dealing with fragmented expectation-causes (i.e. DCC chat split |
| 47 | over two packets, etc.) |
Harald Welte | 3666e0e | 2001-04-12 22:24:29 +0000 | [diff] [blame] | 48 | - conntrack / nat failover [HW] |
| 49 | - brainstorming about 2.5 conntrack code |
| 50 | - netlink interface for conntrack manipulation from userspace [HW] |
| 51 | - unified nfnetlink for queue,ulog,conntrack (and more?) (2.5 issue) |
| 52 | |
James Morris | 47a026d | 2001-11-30 10:55:10 +0000 | [diff] [blame] | 53 | Userspace queuing for 2.5: |
| 54 | - Integration with nfnetlink. |
| 55 | - Multiple queues per protocol. |
| 56 | - Netlink broadcast support. |
| 57 | - Allow multiple reader/writers in userspace. |
| 58 | - How to handle multiple protocols (e.g. use separate queue handlers |
| 59 | or a multiplexer like ipqmpd). |
| 60 | - Peformance improvements: multipart messages, mmaped socket (possibly). |
| 61 | - Simplify queuing logic, which is quite ugly at the moment. (BC suggested |
| 62 | removing logic from kernel). |
| 63 | - Allow userspace to set nfmark. |
| 64 | - Allow userspace to set queue length etc. |
| 65 | - Possibly pass conntrack/NAT info to userspace with packet. |
