David Crawshaw	131541c06d	derp: deflake test Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	72dbf26f63	derp: test that client a->b and a->c relaying do not interfere Without the recent write deadline introduction, this test fails. They still do interfere, but the interference is now bound by the write deadline. Many improvements are possible. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	e838b3fb59	derp: use a write timeout when sending to clients Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	3df1b97ea8	derp: do not treat failure to relay as the fault of the sender If Alice attempts to send a packet to Bob and the DERP server encounters an error on the socket to Bob, we should not disconnect Alice for that.

Brad Fitzpatrick	2cff9016e4	net/dnscache: add overly simplistic DNS cache package for selective use I started to write a full DNS caching resolver and I realized it was overkill and wouldn't work on Windows even in Go 1.14 yet, so I'm doing this tiny one instead for now, just for all our netcheck STUN derp lookups, and connections to DERP servers. (This will be caching a exactly 8 DNS entries, all ours.) Fixes #145 (can be better later, of course)	5 years ago
