Brad Fitzpatrick 95a9adbb97 wgengine/netstack: implement UDP relaying to advertised subnets ... TCP was done in 662fbd4a09. This does the same for UDP. Tested by hand. Integration tests will have to come later. I'd wanted to do it in this commit, but the SOCKS5 server needed for interop testing between two userspace nodes doesn't yet support UDP and I didn't want to invent some whole new userspace packet injection interface at this point, as SOCKS seems like a better route, but that's its own bug. Fixes #2302 RELNOTE=netstack mode can now UDP relay to subnets Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>		2021-07-21 22:32:26 -07:00
