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. Then we can use this for future things rather than slapping more stuff into MapResponse, etc. Change-Id: Ic802078c50d33653ae1f79d1e5257e7ade4408fd Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

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).

Brad Fitzpatrick	b7f1fe7b0d	tailcfg: remove old DNS fields ... The control plane server doesn't send these to modern clients so we don't need them in the tree. The server has its own serialization code to generate legacy MapResponses when needed.

Brad Fitzpatrick	6b71568eb7	util/cloudenv: add Azure support & DNS IPs ... And rewrite cloud detection to try to do only zero or one metadata discovery request for all clouds, only doing a first (or second) as confidence increases. Work remains for Windows, but a start. And add Cloud to tailcfg.Hostinfo, which helped with testing using "tailcfg debug hostinfo".

Ross Zurowski	bb67999808	tailcfg: add TailscaleSSHEnabled helper check (#4812) ... This commit adds a helper to check if Tailscale SSH is enabled. We're currently checking the SSH_HostKeys field in a few places, but later plan to add an explicit bool. This helper makes the check and any future changes easier.

Brad Fitzpatrick	373176ea54	util/codegen: format generated code with goimports, not gofmt ... goimports is a superset of gofmt that also groups imports. (the goimports tool also adds/removes imports as needed, but that part is disabled here) Change-Id: Iacf0408dfd9497f4ed3da4fa50e165359ce38498 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Tom DNetto	24cd26534f	hostinfo, tailcfg: add desktop detection on Linux to hostinfo ... From the machines tab its hard to differenciate desktop Linux installs from server Linux installs. Transmitting this information should make this determination a lot easier. Due to the reality that tailscaled is likely a system process, the standard checks based on XDG_SESSION_TYPE or DISPLAY environment variables are not possible (those variables won't be set). Instead, we look for listening unix sockets that are typical of desktop installs. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
