Brad Fitzpatrick	e6983baa73	cmd/tailscale/cli: fix macOS crash reading envknob in init (#11667) ... And add a test. Regression from a5e1f7d703 Fixes tailscale/corp#19036 Change-Id: If90984049af0a4820c96e1f77ddf2fce8cb3043f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 weeks ago
Chloé Vulquin	0f3a292ebd	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. Updates #11645 Signed-off-by: Chloé Vulquin <code@toast.bunkerlabs.net>	3 weeks ago

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.

Maisem Ali	3f4c5daa15	wgengine/netstack: remove SubnetRouterWrapper ... It was used when we only supported subnet routers on linux and would nil out the SubnetRoutes slice as no other router worked with it, but now we support subnet routers on ~all platforms. The field it was setting to nil is now only used for network logging and nowhere else, so keep the field but drop the SubnetRouterWrapper 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.

Joe Tsai	e2586bc674	logtail: always zstd compress with FastestCompression and LowMemory (#11583) ... This is based on empirical testing using actual logs data. FastestCompression only incurs a marginal <1% compression ratio hit for a 2.25x reduction in memory use for small payloads (which are common if log uploads happen at a decently high frequency). The memory savings for large payloads is much lower (less than 1.1x reduction). LowMemory only incurs a marginal <5% hit on performance for a 1.6-2.0x reduction in memory use for small or large payloads. The memory gains for both settings justifies the loss of benefits, which are arguably minimal. tailscale/corp#18514 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	1 month ago
