Joe Tsai	7a77a2edf1	logtail: optimize JSON processing (#11671 ) Changes made: * Avoid "encoding/json" for JSON processing, and instead use "github.com/go-json-experiment/json/jsontext". Use jsontext.Value.IsValid for validation, which is much faster. Use jsontext.AppendQuote instead of our own JSON escaping. * In drainPending, use a different maxLen depending on lowMem. In lowMem mode, it is better to perform multiple uploads than it is to construct a large body that OOMs the process. * In drainPending, if an error is encountered draining, construct an error message in the logtail JSON format rather than something that is invalid JSON. * In appendTextOrJSONLocked, use jsontext.Decoder to check whether the input is a valid JSON object. This is faster than the previous approach of unmarshaling into map[string]any and then re-marshaling that data structure. This is especially beneficial for network flow logging, which produces relatively large JSON objects. * In appendTextOrJSONLocked, enforce maxSize on the input. If too large, then we may end up in a situation where the logs can never be uploaded because it exceeds the maximum body size that the Tailscale logs service accepts. * Use "tailscale.com/util/truncate" to properly truncate a string on valid UTF-8 boundaries. * In general, remove unnecessary spaces in JSON output.

Aaron Klotz	4d5d669cd5	net/dns: unconditionally write NRPT rules to local settings We were being too aggressive when deciding whether to write our NRPT rules to the local registry key or the group policy registry key. After once again reviewing the document which calls itself a spec (see issue), it is clear that the presence of the DnsPolicyConfig subkey is the important part, not the presence of values set in the DNSClient subkey. Furthermore, a footnote indicates that the presence of DnsPolicyConfig in the GPO key will always override its counterpart in the local key. The implication of this is important: we may unconditionally write our NRPT rules to the local key. We copy our rules to the policy key only when it contains NRPT rules belonging to somebody other than us.

James Tucker	8fa3026614	tsweb: switch to fastuuid for request ID generation Request ID generation appears prominently in some services cumulative allocation rate, and while this does not eradicate this issue (the API still makes UUID objects), it does improve the overhead of this API and reduce the amount of garbage that it produces.

James Tucker	d0f3fa7d7e	util/fastuuid: add a more efficient uuid generator This still generates github.com/google/uuid UUID objects, but does so using a ChaCha8 CSPRNG from the stdlib rand/v2 package. The public API is backed by a sync.Pool to provide good performance in highly concurrent operation. Under high load the read API produces a lot of extra garbage and overhead by way of temporaries and syscalls. This implementation reduces both to minimal levels, and avoids any long held global lock by utilizing sync.Pool.

Joe Tsai	b4ba492701	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.

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>	7 months ago

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.
