Brad Fitzpatrick	7e016c1d90	ipn/ipnserver: remove IPN protocol server Unused in this repo as of the earlier #6450 (`300aba61a6`) and unused in the Windows GUI as of tailscale/corp#8065. With this ipn.BackendServer is no longer used and could also be removed from this repo. The macOS and iOS clients still temporarily depend on it, but I can move it to that repo instead while and let its migration proceed on its own schedule while we clean this repo up.

Brad Fitzpatrick	1fdfb0dd08	ipn/localapi: add "enginestatus" debug command to LocalAPI To force an EngineStatus update to the IPN bus. This is a temporary measure while migrating the Windows GUI entirely to the LocalAPI and off the old IPN protocol. The old IPN protocol had RequestEngineStatus and LocalAPI didn't.

Maisem Ali	dd50dcd067	ipn/ipnlocal: handle untagging nodes better We would end up with duplicate profiles for the node as the UserID would have chnaged. In order to correctly deduplicate profiles, we need to look at both the UserID and the NodeID. A single machine can only ever have 1 profile per NodeID and 1 profile per UserID. Note: UserID of a Node can change when the node is tagged/untagged, and the NodeID of a device can change when the node is deleted so we need to check for both.

Maisem Ali	235309adc4	all: store NL keys per profile This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct. This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey. It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional to be able to delete the "/tka" dir if it exists. This means that we will have a unique key per profile, and a unique directory per profile. Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not delete the ChonkDir. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago

Brad Fitzpatrick	3f8e185003	health: add Warnable, move ownership of warnable items to callers The health package was turning into a rando dumping ground. Make a new Warnable type instead that callers can request an instance of, and then Set it locally in their code without the health package being aware of all the things that are warnable. (For plenty of things the health package will want to know details of how Tailscale works so it can better prioritize/suppress errors, but lots of the warnings are pretty leaf-y and unrelated) This just moves two of the health warnings.

Aaron Klotz	73b8968404	ipn/ipnlocal: ensure Persist information is saved to server mode start state Numerous issues have been filed concerning an inability to install and run Tailscale headlessly in unattended mode, particularly after rebooting. The server mode `Prefs` stored in `server-state.conf` were not being updated with `Persist` state once the node had been succesfully logged in. Users have been working around this by finagling with the GUI to make it force a state rewrite. This patch makes that unnecessary by ensuring the required server mode state is updated when prefs are updated by the control client.

Brad Fitzpatrick	9be8d15979	ipn/localapi: refactor some cert code in prep for a move I want to move the guts (after the HTTP layer) of the certificate fetching into the ipnlocal package, out of localapi.

One of the methods needed nothing from its receiver. This will make a future change easier to reason about.

This happens in the first place because we release b.mu during network RPCs.

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.

Brad Fitzpatrick	88c2afd1e3	ipn/ipnlocal, net/dns, util/cloudenv: specialize DNS config on Google Cloud This does three things: If you're on GCP, it adds a .internal DNS split route to the metadata server, so we never break GCP DNS names. This lets people have some Tailscale nodes on GCP and some not (e.g. laptops at home) without having to add a Tailnet-wide .internal DNS route. If you already have such a route, though, it won't overwrite it. * If the 100.100.100.100 DNS forwarder has nowhere to forward to, it forwards it to the GCP metadata IP, which forwards to 8.8.8.8. This means there are never errNoUpstreams ("upstream nameservers not set") errors on GCP due to e.g. mangled /etc/resolv.conf (GCP default VMs don't have systemd-resolved, so it's likely a DNS supremacy fight) * makes the DNS fallback mechanism use the GCP metadata IP as a fallback before our hosted HTTP-based fallbacks I created a default GCP VM from their web wizard. It has no systemd-resolved. I then made its /etc/resolv.conf be empty and deleted its GCP hostnames in /etc/hosts. I then logged in to a tailnet with no global DNS settings. With this, tailscaled writes /etc/resolv.conf (direct mode, as no systemd-resolved) and sets it to 100.100.100.100, which then has regular DNS via the metadata IP and .internal DNS via the metadata IP as well. If the tailnet configures explicit DNS servers, those are used instead, except for .internal. This also adds a new util/cloudenv package based on version/distro where the cloud type is only detected once. We'll likely expand it in the future for other clouds, doing variants of this change for other popular cloud environments.
