Brad Fitzpatrick	1a963342c7	util/set: add Of variant of SetOf that takes variadic parameter ... set.Of(1, 2, 3) is prettier than set.SetOf([]int{1, 2, 3}). I was going to change the signature of SetOf but then I noticed its name has stutter anyway, so I kept it for compatibility. People can prefer to use set.Of for new code or slowly migrate. Also add a lazy Make method, which I often find myself wanting, without having to resort to uglier mak.Set(&set, k, struct{}{}).

Will Norris	46980c9664	tsweb: ensure in-flight requests are always marked as finished ... The inflight request tracker only starts recording a new bucket after the first non-error request. Unfortunately, it's written in such a way that ONLY successful requests are ever marked as being finished. Once a bucket has had at least one successful request and begun to be tracked, all subsequent error cases are never marked finished and always appear as in-flight. This change ensures that if a request is recorded has having been started, we also mark it as finished at the end.

Brad Fitzpatrick	e42c4396cf	net/netcheck: don't spam on ICMP socket permission denied errors ... While debugging a failing test in airplane mode on macOS, I noticed netcheck logspam about ICMP socket creation permission denied errors. Apparently macOS just can't do those, or at least not in airplane mode. Not worth spamming about.

Brad Fitzpatrick	15fc6cd966	derp/derphttp: fix netcheck HTTPS probes ... The netcheck client, when no UDP is available, probes distance using HTTPS. Several problems: * It probes using /derp/latency-check. * But cmd/derper serves the handler at /derp/probe * Despite the difference, it work by accident until c8f4dfc8c0 which made netcheck's probe require a 2xx status code. * in tests, we only use derphttp.Handler, so the cmd/derper-installed mux routes aren't preesnt, so there's no probe. That breaks tests in airplane mode. netcheck.Client then reports "unexpected HTTP status 426" (Upgrade Required) This makes derp handle both /derp/probe and /derp/latency-check equivalently, and in both cmd/derper and derphttp.Handler standalone modes. I notice this when wgengine/magicsock TestActiveDiscovery was failing in airplane mode (no wifi). It still doesn't pass, but it gets further.

Irbe Krumina	19b31ac9a6	cmd/{k8s-operator,k8s-nameserver},k8s-operator: update nameserver config with records for ingress/egress proxies (#11019) ... cmd/k8s-operator: optionally update dnsrecords Configmap with DNS records for proxies. This commit adds functionality to automatically populate DNS records for the in-cluster ts.net nameserver to allow cluster workloads to resolve MagicDNS names associated with operator's proxies. The records are created as follows: * For tailscale Ingress proxies there will be a record mapping the MagicDNS name of the Ingress device and each proxy Pod's IP address. * For cluster egress proxies, configured via tailscale.com/tailnet-fqdn annotation, there will be a record for each proxy Pod, mapping the MagicDNS name of the exposed tailnet workload to the proxy Pod's IP. No records will be created for any other proxy types. Records will only be created if users have configured the operator to deploy an in-cluster ts.net nameserver by applying tailscale.com/v1alpha1.DNSConfig. It is user's responsibility to add the ts.net nameserver as a stub nameserver for ts.net DNS names. https://kubernetes.io/docs/tasks/administer-cluster/dns-custom-nameservers/#configuration-of-stub-domain-and-upstream-nameserver-using-coredns https://cloud.google.com/kubernetes-engine/docs/how-to/kube-dns#upstream_nameservers See also https://github.com/tailscale/tailscale/pull/11017 Updates tailscale/tailscale#10499 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	6 months ago

Jonathan Nobels	fa1303d632	net/netmon: swap to swift-derived defaultRoute on macos (#11936) ... Updates tailscale/corp#18960 iOS uses Apple's NetworkMonitor to track the default interface and there's no reason we shouldn't also use this on macOS, for the same reasons noted in the comments for why this change was made on iOS. This eliminates the need to load and parse the routing table when querying the defaultRouter() in almost all cases. A slight modification here (on both platforms) to fallback to the default BSD logic in the unhappy-path rather than making assumptions that may not hold. If netmon is eventually parsing AF_ROUTE and able to give a consistently correct answer for the default interface index, we can fall back to that and eliminate the Swift dependency.

Irbe Krumina	44aa809cb0	cmd/{k8s-nameserver,k8s-operator},k8s-operator: add a kube nameserver, make operator deploy it (#11919) ... * cmd/k8s-nameserver,k8s-operator: add a nameserver that can resolve ts.net DNS names in cluster. Adds a simple nameserver that can respond to A record queries for ts.net DNS names. It can respond to queries from in-memory records, populated from a ConfigMap mounted at /config. It dynamically updates its records as the ConfigMap contents changes. It will respond with NXDOMAIN to queries for any other record types (AAAA to be implemented in the future). It can respond to queries over UDP or TCP. It runs a miekg/dns DNS server with a single registered handler for ts.net domain names. Queries for other domain names will be refused. The intended use of this is: 1) to allow non-tailnet cluster workloads to talk to HTTPS tailnet services exposed via Tailscale operator egress over HTTPS 2) to allow non-tailnet cluster workloads to talk to workloads in the same cluster that have been exposed to tailnet over their MagicDNS names but on their cluster IPs. DNSConfig CRD can be used to configure the operator to deploy kube nameserver (./cmd/k8s-nameserver) to cluster.

Shaw Drastin	1fe073098c	Reset dial plan when switching profile (#11933) ... When switching profile, the server URL can change (e.g. because of switching to a self-hosted headscale instance). If it is not reset here, dial plans returned by old server (e.g. tailscale control server) will be used to connect to new server (e.g. self-hosted headscale server), and the register request will be blocked by it until timeout, leading to very slow profile switches.
