Mihai Parparita	9d04ffc782	net/wsconn: add back custom wrapper for turning a websocket.Conn into a net.Conn We removed it in #4806 in favor of the built-in functionality from the nhooyr.io/websocket package. However, it has an issue with deadlines that has not been fixed yet (see nhooyr/websocket#350). Temporarily go back to using a custom wrapper (using the fix from our fork) so that derpers will stop closing connections too aggressively.

Joe Tsai	82f5f438e0	wgengine/wgcfg: plumb down audit log IDs (#5855 ) The node and domain audit log IDs are provided in the map response, but are ultimately going to be used in wgengine since that's the layer that manages the tstun.Wrapper.

Brad Fitzpatrick	8a0cb4ef20	control/controlclient: fix recent set-dns regression SetDNS calls were broken by `6d04184325` the other day. Unreleased. Caught by tests in another repo. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	fb4e23506f	control/controlclient: stop restarting map polls on health change At some point we started restarting map polls on health change, but we don't remember why. Maybe it was a desperate workaround for something. I'm not sure it ever worked. Rather than have a haunted graveyard, remove it. In its place, though, and somewhat as a safety backup, send those updates over the HTTP/2 noise channel if we have one open. Then if there was a reason that a map poll restart would help we could do it server-side. But mostly we can gather error stats and show machine-level health info for debugging.

Brad Fitzpatrick	6d04184325	control/controlclient: add a noiseClient.post helper method In prep for a future change that would've been very copy/paste-y. And because the set-dns call doesn't currently use a context, so timeouts/cancelations are plumbed. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Mihai Parparita	1ce0e558a7	cmd/derper, control/controlhttp: disable WebSocket compression The data that we send over WebSockets is encrypted and thus not compressible. Additionally, Safari has a broken implementation of compression (see nhooyr/websocket#218) that makes enabling it actively harmful.

Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114.

Maisem Ali	c60cbca371	control/controlclient: store netinfo and hostinfo separately Currently, when SetNetInfo is called it sets the value on hostinfo.NetInfo. However, when SetHostInfo is called it overwrites the hostinfo field which may mean it also clears out the NetInfo it had just received. This commit stores NetInfo separately and combines it into Hostinfo as needed so that control is always notified of the latest values. Also, remove unused copies of Hostinfo from ipn.Status and controlclient.Auto. Updates #tailscale/corp#4824 (maybe fixes) Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
