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.

Andrew Dunham	e1bdbfe710	tailcfg, control/controlhttp, control/controlclient: add ControlDialPlan field (#5648 ) * tailcfg, control/controlhttp, control/controlclient: add ControlDialPlan field This field allows the control server to provide explicit information about how to connect to it; useful if the client's link status can change after the initial connection, or if the DNS settings pushed by the control server break future connections.

Aaron Klotz	acc7baac6d	tailcfg, util/deephash: add DataPlaneAuditLogID to Node and DomainDataPlaneAuditLogID to MapResponse We're adding two log IDs to facilitate data-plane audit logging: a node-specific log ID, and a domain-specific log ID.

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. Fixes #5617 Fixes tailscale/corp#1475 Change-Id: I72404e1789f9e56ec47f9b7021b44c025f7a373a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Brad Fitzpatrick	58abae1f83	net/dns/{publicdns,resolver}: add NextDNS DoH support NextDNS is unique in that users create accounts and then get user-specific DNS IPs & DoH URLs. For DoH, the customer ID is in the URL path. For IPv6, the IP address includes the customer ID in the lower bits. For IPv4, there's a fragile "IP linking" mechanism to associate your public IPv4 with an assigned NextDNS IPv4 and that tuple maps to your customer ID. We don't use the IP linking mechanism. Instead, NextDNS is DoH-only. Which means using NextDNS necessarily shunts all DNS traffic through 100.100.100.100 (programming the OS to use 100.100.100.100 as the global resolver) because operating systems can't usually do DoH themselves. Once it's in Tailscale's DoH client, we then connect out to the known NextDNS IPv4/IPv6 anycast addresses. If the control plane sends the client a NextDNS IPv6 address, we then map it to the corresponding NextDNS DoH with the same client ID, and we dial that DoH server using the combination of v4/v6 anycast IPs.
