James Tucker db760d0bac cmd/tailscaled: move cleanup to an implicit action during startup
This removes a potentially increased boot delay for certain boot
topologies where they block on ExecStartPre that may have socket
activation dependencies on other system services (such as
systemd-resolved and NetworkManager).

Also rename cleanup to clean up in affected/immediately nearby places
per code review commentary.

logtail: require Buffer.Write to not retain the provided slice (#11617)
Buffer.Write has the exact same signature of io.Writer.Write.
The latter requires that implementations to never retain
the provided input buffer, which is an expectation that most
users will have when they see a Write signature.

The current behavior of Buffer.Write where it does retain
the input buffer is a risky precedent to set.
Switch the behavior to match io.Writer.Write.

There are only two implementations of Buffer in existence:
* logtail.memBuffer
* filch.Filch

The former can be fixed by cloning the input to Write.
This will cause an extra allocation in every Write,
but we can fix that will pooling on the caller side
in a follow-up PR.

The latter only passes the input to os.File.Write,
which does respect the io.Writer.Write requirements.

Brad Fitzpatrick b27238b654 derp/derphttp: don't block in LocalAddr method
The derphttp.Client mutex is held during connects (for up to 10
seconds) so this LocalAddr method (blocking on said mutex) could also
block for up to 10 seconds, causing a pileup upstream in
magicsock/wgengine and ultimately a watchdog timeout resulting in a

cli/configure: respect $KUBECONFIG (#11604)
cmd/tailscale/cli: respect $KUBECONFIG

* `$KUBECONFIG` is a `$PATH`-like: it defines a *list*.
`tailscale config kubeconfig` works like the rest of the
ecosystem so that if $KUBECONFIG is set it will write to the first existant file in the list, if none exist then
the final entry in the list.
* if `$KUBECONFIG` is an empty string, the old logic takes over.

Notes:

* The logic for file detection is inlined based on what `kind` does.
Technically it's a race condition, since the file could be removed/added
in between the processing steps, but the fallout shouldn't be too bad.
https://github.com/kubernetes-sigs/kind/blob/v0.23.0-alpha/pkg/cluster/internal/kubeconfig/internal/kubeconfig/paths.go

* The sandboxed (App Store) variant relies on a specific temporary
entitlement to access the ~/.kube/config file.
The entitlement is only granted to specific files, and so is not
applicable to paths supplied by the user at runtime.
While there may be other ways to achieve this access to arbitrary
kubeconfig files, it's out of scope for now.

Anton Tolchanov 5336362e64 prober: export probe class and metrics from bandwidth prober
- Wrap each prober function into a probe class that allows associating
  metric labels and custom metrics with a given probe;
- Make sure all existing probe classes set a `class` metric label;
- Move bandwidth probe size from being a metric label to a separate
  gauge metric; this will make it possible to use it to calculate
  average used bandwidth using a PromQL query;
- Also export transfer time for the bandwidth prober (more accurate than
  the total probe time, since it excludes connection establishment
  time).

Brad Fitzpatrick a5e1f7d703 ipn/{ipnlocal,localapi}: add API to toggle use of exit node
This is primarily for GUIs, so they don't need to remember the most
recently used exit node themselves.

This adds some CLI commands, but they're disabled and behind the WIP
envknob, as we need to consider naming (on/off is ambiguous with
running an exit node, etc) as well as automatic exit node selection in
the future. For now the CLI commands are effectively developer debug
things to test the LocalAPI.

as it's not useful.

Brad Fitzpatrick aa084a29c6 ipn/ipnlocal: name the unlockOnce type, plumb more, add Unlock method
This names the func() that Once-unlocked LocalBackend.mu. It does so
both for docs and because it can then have a method: Unlock, for the
few points that need to explicitly unlock early (the cause of all this
mess). This makes those ugly points easy to find, and also can then
make them stricter, panicking if the mutex is already unlocked. So a
normal call to the func just once-releases the mutex, returning false
if it's already done, but the Unlock method is the strict one.

Then this uses it more, so most the b.mu.Unlock calls remaining are
simple cases and usually defers.

Brad Fitzpatrick 5e7c0b025c ipn/ipnlocal: add some "lockedOnEntry" helpers + guardrails, fix bug
A number of methods in LocalBackend (with suffixed "LockedOnEntry")
require b.mu be held but unlock it on the way out. That's asymmetric
and atypical and error prone.

This adds a helper method to LocalBackend that locks the mutex and
returns a sync.OnceFunc that unlocks the mutex. Then we pass around
that unlocker func down the chain to make it explicit (and somewhat
type check the passing of ownership) but also let the caller defer
unlock it, in the case of errors/panics that happen before the callee
gets around to calling the unlock.

This revealed a latent bug in LocalBackend.DeleteProfile which double
unlocked the mutex.

James Tucker 6e334e64a1 net/netcheck,wgengine/magicsock: align DERP frame receive time heuristics
The netcheck package and the magicksock package coordinate via the
health package, but both sides have time based heuristics through
indirect dependencies. These were misaligned, so the implemented
heuristic aimed at reducing DERP moves while there is active traffic
were non-operational about 3/5ths of the time.

It is problematic to setup a good test for this integration presently,
so instead I added comment breadcrumbs along with the initial fix.
