| Summary | 0002065: ICMP support should be added | ||||
| Description | ICMPv6 is likely to be particularly critical for routing IPv6 traffic nicely (MTU-discovery!). | ||||
| Tags | No tags attached. | ||||
| related to | 0002064 | closed | Christian Grothoff | new VPN service (working with new exit/dns services) needs to be fully implemented and tested |
|
|
TUN library now has ICMP support. |
|
|
Exit daemon has ICMP support as of 19295. However, we might still want to restrict which ICMP types the exit will allow out to the Internet/Service and the mesh-message format might still change (or the data sent might be subject to additional sanitation). See FIXME's in the code. |
|
|
VPN now has rudimentary ICMP support. Code to translate ports/IP addresses in ICMP payload is missing. Also, there is no story yet for translating between ICMPv4 to ICMPv6 and back (that'll be a bit more funky stuff). |
|
|
Documented how ICMP PT should work with the messages. Also specified where we leave out the ICMP payload as it is useless to the other side due to NAT (the exit/vpn will have to make up the full IP+8-bytes of payload anyway for certain message types). |
|
|
Exit daemon now properly discards ICMP payload for messages from TUN to MESH. |
|
|
VPN service now properly discards ICMP payloads for messages from TUN to MESH. VPN also considers PT issues and modifies ICMP types from ICMPv4 to ICMPv6 as necessary (SVN 19302). Open issues include: 1) Synthesis of ICMP payload by exit for certain message types (done in SVN 19307) 2) Synthesis of ICMP payload by vpn for certain message types (done in SVN 19305) 3) ICMP protocol translation by exit (to service) towards TUN (done in SVN 19307) 4) ICMP protocol translation by vpn towards TUN (done in SVN 19304) 5) Might want to move ICMP PT code to TUN library... |

Declaring victory for now; (5) above does not seem very feasible or critical at this point. |
