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
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.

Eng Zer Jun	f0347e841f	refactor: move from io/ioutil to io and os packages The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit replaces the existing io/ioutil functions with their new definitions in io and os packages.

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	c66f99fcdc	tailcfg, control/controlclient, ipn/ipnlocal: add c2n (control-to-node) system This lets the control plane can make HTTP requests to nodes.

Tom DNetto	4001d0bf25	assorted: plumb tka initialization & network-lock key into tailscaled - A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration. - If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

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

Brad Fitzpatrick	d5f8f38ac6	tailcfg: rename map request version to "capability version" And add a CapabilityVersion type, primarily for documentation. This makes MapRequest.Version, RegisterRequest.Version, and SetDNSRequest.Version all use the same version, which will avoid confusing in the future if Register or SetDNS ever changed their semantics on Version change. (Currently they're both always 1) This will requre a control server change to allow a SetDNSRequest.Version value other than 1 to be deployed first.
