Brad Fitzpatrick	0d991249e1	types/netmap: remove NetworkMap.{Addresses,MachineStatus} And convert all callers over to the methods that check SelfNode. Now we don't have multiple ways to express things in tests (setting fields on SelfNode vs NetworkMap, sometimes inconsistently) and don't have multiple ways to check those two fields (often only checking one or the other).

Brad Fitzpatrick	9538e9f970	ipn/ipnlocal: keep internal map updated of latest Nodes post mutations We have some flaky integration tests elsewhere that have no one place to ask about the state of the world. This makes LocalBackend be that place (as it's basically there anyway) but doesn't yet add the ForTest accessor method. This adds a LocalBackend.peers map[NodeID]NodeView that is incrementally updated as mutations arrive. And then we start moving away from using NetMap.Peers at runtime (UpdateStatus no longer uses it now). And remove another copy of NodeView in the LocalBackend nodeByAddr map. Change that to point into b.peers instead. Future changes will then start streaming whole-node-granularity peer change updates to WatchIPNBus clients, tracking statefully per client what each has seen. This will get the GUI clients from receiving less of a JSON storm of updates all the time.

Brad Fitzpatrick	ea4425d8a9	ipn/ipnlocal, wgengine/magicsock: move UpdateStatus stuff around Upcoming work on incremental netmap change handling will require some replumbing of which subsystems get notified about what. Done naively, it could break "tailscale status --json" visibility later. To make sure I understood the flow of all the updates I was rereading the status code and realized parts of ipnstate.Status were being populated by the wrong subsystems. The engine (wireguard) and magicsock (data plane, NAT traveral) should only populate the stuff that they uniquely know. The WireGuard bits were fine but magicsock was populating stuff stuff that LocalBackend could've better handled, so move it there.

Brad Fitzpatrick	4511e7d64e	ipn/ipnstate: add PeerStatus.AltSharerUserID, stop mangling Node.User In `b987b2ab18` (2021-01-12) when we introduced sharing we mapped the sharer to the userid at a low layer, mostly to fix the display of "tailscale status" and the client UIs, but also some tests. The commit earlier today, `7dec09d169`, removed the 2.5yo option to let clients disable that automatic mapping, as clearly we were never getting around to it. This plumbs the Sharer UserID all the way to ipnstatus so the CLI itself can choose to print out the Sharer's identity over the node's original owner. Then we stop mangling Node.User and let clients decide how they want to render things. To ease the migration for the Windows GUI (which currently operates on tailcfg.Node via the NetMap from WatchIPNBus, instead of PeerStatus), a new method Node.SharerOrUser is added to do the mapping of Sharer-else-User.

Andrew Lytvynov	c1ecae13ab	ipn/{ipnlocal,localapi}: actually renew certs before expiry (#8731 ) While our `shouldStartDomainRenewal` check is correct, `getCertPEM` would always bail if the existing cert is not expired. Add the same `shouldStartDomainRenewal` check to `getCertPEM` to make it proceed with renewal when existing certs are still valid but should be renewed. The extra check is expensive (ARI request towards LetsEncrypt), so cache the last check result for 1hr to not degrade `tailscale serve` performance. Also, asynchronous renewal is great for `tailscale serve` but confusing for `tailscale cert`. Add an explicit flag to `GetCertPEM` to force a synchronous renewal for `tailscale cert`.

The core issue this addresses for now is that when run on Windows there can be no code paths that attempt to use an invalid UID string, which on Windows is described in [1]. For the goos="linux" tests, we now explicitly skip the affected migration code if runtime.GOOS=="windows", and for the Windows test we explicitly use the running users uid, rather than just the string "user1". We also now make the case where a profile exists and has already been migrated a non-error condition toward the outer API.

Maisem Ali	c3ef6fb4ee	ipn/ipnlocal: handle masquerade addresses in PeerAPI Without this, the peer fails to do anything over the PeerAPI if it has a masquerade address. ``` Apr 19 13:58:15 hydrogen tailscaled[6696]: peerapi: invalid request from <ip>:58334: 100.64.0.1/32 not found in self addresses ``` Updates #8020 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Mihai Parparita	d0906cda97	net/sockstats: expose debug info Exposes some internal state of the sockstats package via the C2N and PeerAPI endpoints, so that it can be used for debugging. For now this includes the estimated radio on percentage and a second-by-second view of the times the radio was active. Also fixes another off-by-one error in the radio on percentage that was leading to >100% values (if n seconds have passed since we started to monitor, there may be n + 1 possible seconds where the radio could have been on).

Andrew Dunham	280255acae	various: add golangci-lint, fix issues (#7905 ) This adds an initial and intentionally minimal configuration for golang-ci, fixes the issues reported, and adds a GitHub Action to check new pull requests against this linter configuration.

Mihai Parparita	9a655a1d58	net/dnsfallback: more explicitly pass through logf function Redoes the approach from #5550 and #7539 to explicitly pass in the logf function, instead of having global state that can be overridden. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
James Tucker	8dec1a8724	.github/workflows: reenable Windows CI, disable broken tests We accidentally switched to ./tool/go in `4022796484` which resulted in no longer running Windows builds, as this is attempting to run a bash script. I was unable to quickly fix the various tests that have regressed, so instead I've added skips referencing #7876, which we need to back and fix.

Mihai Parparita	cef0a474f8	ipn/ipnlocal: check that sockstatLogger is available in c2n endpoint Otherwise there may be a panic if it's nil (and the control side of the c2n call will just time out). Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	03b2c44a21	ipn/ipnlocal: more explicitly say if sockstats are not available Makes it more apparent in the PeerAPI endpoint that the client was not built with the appropriate toolchain or build tags.

Will Norris	5a3da3cd7f	ipn: add sockstat logger to stable builds This makes the sockstat logger available on all builds, but only enables it by default for unstable. For stable builds, the logger must be explicitly enabled via C2N component logger. Updates tailscale/corp#9230 Updates #3363 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Aaron Klotz	90fd04cbde	ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled I realized that a lot of the problems that we're seeing around migration and LocalBackend state can be avoided if we drive Windows pref migration entirely from within tailscaled. By doing it this way, tailscaled can automatically perform the migration as soon as the connection with the client frontend is established. Since tailscaled is already running as LocalSystem, it already has access to the user's local AppData directory. The profile manager already knows which user is connected, so we simply need to resolve the user's prefs file and read it from there. Of course, to properly migrate this information we need to also check system policies. I moved a bunch of policy resolution code out of the GUI and into a new package in util/winutil/policy.

Maisem Ali	e0d291ab8a	ipn/store: add support for stores to hook into a custom dialer For stores like k8s secrets we need to dial out to the k8s API as though Tailscale wasn't running. The issue currently only manifests when you try to use an exit node while running inside a k8s cluster and are trying to use Kubernetes secrets as the backing store. This doesn't address cmd/containerboot, which I'll do in a follow up. Updates #7695 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Andrew Dunham	c98652c333	doctor/permissions: add new check to print process permissions Since users can run tailscaled in a variety of ways (root, non-root, non-root with process capabilities on Linux), this check will print the current process permissions to the log to aid in debugging.
