Brad Fitzpatrick	86e0f9b912	net/ipset, wgengine/filter/filtertype: add split-out packages This moves NewContainsIPFunc from tsaddr to new ipset package. And wgengine/filter types gets split into wgengine/filter/filtertype, so netmap (and thus the CLI, etc) doesn't need to bring in ipset, bart, etc. Then add a test making sure the CLI deps don't regress.

Brad Fitzpatrick	64ac64fb66	net/tsaddr: use bart in NewContainsIPFunc, add tests, benchmarks NewContainsIPFunc was previously documented as performing poorly if there were many netip.Prefixes to search over. As such, we never it used it in such cases. This updates it to use bart at a certain threshold (over 6 prefixes, currently), at which point the bart lookup overhead pays off. This is currently kinda useless because we're not using it. But now we can and get wins elsewhere. And we can remove the caveat in the docs. goos: darwin goarch: arm64 pkg: tailscale.com/net/tsaddr │ before │ after │ │ sec/op │ sec/op vs base │ NewContainsIPFunc/empty-8 2.215n ± 11% 2.239n ± 1% +1.08% (p=0.022 n=10) NewContainsIPFunc/cidr-list-1-8 17.44n ± 0% 17.59n ± 6% +0.89% (p=0.000 n=10) NewContainsIPFunc/cidr-list-2-8 27.85n ± 0% 28.13n ± 1% +1.01% (p=0.000 n=10) NewContainsIPFunc/cidr-list-3-8 36.05n ± 0% 36.56n ± 13% +1.41% (p=0.000 n=10) NewContainsIPFunc/cidr-list-4-8 43.73n ± 0% 44.38n ± 1% +1.50% (p=0.000 n=10) NewContainsIPFunc/cidr-list-5-8 51.61n ± 2% 51.75n ± 0% ~ (p=0.101 n=10) NewContainsIPFunc/cidr-list-10-8 95.65n ± 0% 68.92n ± 0% -27.94% (p=0.000 n=10) NewContainsIPFunc/one-ip-8 4.466n ± 0% 4.469n ± 1% ~ (p=0.491 n=10) NewContainsIPFunc/two-ip-8 8.002n ± 1% 7.997n ± 4% ~ (p=0.697 n=10) NewContainsIPFunc/three-ip-8 27.98n ± 1% 27.75n ± 0% -0.82% (p=0.012 n=10) geomean 19.60n 19.07n -2.71% Updates #12486 Change-Id: I2e2320cc4384f875f41721374da536bab995c1ce Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 months ago

James Tucker	8d1249550a	net/netcheck,wgengine/magicsock: add potential workaround for Palo Alto DIPP misbehavior Palo Alto firewalls have a typically hard NAT, but also have a mode called Persistent DIPP that is supposed to provide consistent port mapping suitable for STUN resolution of public ports. Persistent DIPP works initially on most Palo Alto firewalls, but some models/software versions have a bug which this works around. The bug symptom presents as follows: - STUN sessions resolve a consistent public IP:port to start with - Much later netchecks report the same IP:Port for a subset of sessions, most often the users active DERP, and/or the port related to sustained traffic. - The broader set of DERPs in a full netcheck will now consistently observe a new IP:Port. - After this point of observation, new inbound connections will only succeed to the new IP:Port observed, and existing/old sessions will only work to the old binding. In this patch we now advertise the lowest latency global endpoint discovered as we always have, but in addition any global endpoints that are observed more than once in a single netcheck report. This should provide viable endpoints for potential connection establishment across a NAT with this behavior.

Irbe Krumina	b5dbf155b1	cmd/k8s-operator: default nameserver image to tailscale/k8s-nameserver:unstable (#11991 ) We are now publishing nameserver images to tailscale/k8s-nameserver, so we can start defaulting the images if users haven't set them explicitly, same as we already do with proxy images. The nameserver images are currently only published for unstable track, so we have to use the static 'unstable' tag. Once we start publishing to stable, we can make the operator default to its own tag (because then we'll know that for each operator tag X there is also a nameserver tag X as we always cut all images for a given tag.

Brad Fitzpatrick	e968b0ecd7	cmd/tailscale,controlclient,ipnlocal: fix 'up', deflake tests more The CLI's "up" is kinda chaotic and LocalBackend.Start is kinda chaotic and they both need to be redone/deleted (respectively), but this fixes some buggy behavior meanwhile. We were previously calling StartLoginInteractive (to start the controlclient's RegisterRequest) redundantly in some cases, causing test flakes depending on timing and up's weird state machine. We only need to call StartLoginInteractive in the client if Start itself doesn't. But Start doesn't tell us that. So cheat a bit and a put the information about whether there's a current NodeKey in the ipn.Status. It used to be accessible over LocalAPI via GetPrefs as a private key but we removed that for security. But a bool is fine. So then only call StartLoginInteractive if that bool is false and don't do it in the WatchIPNBus loop.

Brad Fitzpatrick	f3d2fd22ef	cmd/tailscale/cli: don't start WatchIPNBus until after up's initial Start The CLI "up" command is a historical mess, both on the CLI side and the LocalBackend side. We're getting closer to cleaning it up, but in the meantime it was again implicated in flaky tests. In this case, the background goroutine running WatchIPNBus was very occasionally running enough to get to its StartLoginInteractive call before the original goroutine did its Start call. That meant integration tests were very rarely but sometimes logging in with the default control plane URL out on the internet (controlplane.tailscale.com) instead of the localhost control server for tests. This also might've affected new Headscale etc users on initial "up".

Nick Khyl	caa3d7594f	ipn/ipnlocal, net/tsdial: plumb routes into tsdial and use them in UserDial We'd like to use tsdial.Dialer.UserDial instead of SystemDial for DNS over TCP. This is primarily necessary to properly dial internal DNS servers accessible over Tailscale and subnet routes. However, to avoid issues when switching between Wi-Fi and cellular, we need to ensure that we don't retain connections to any external addresses on the old interface. Therefore, we need to determine which dialer to use internally based on the configured routes. This plumbs routes and localRoutes from router.Config to tsdial.Dialer, and updates UserDial to use either the peer dialer or the system dialer, depending on the network address and the configured routes.

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.

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

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.

Metrics cannot currently be enabled for proxies that egress traffic to tailnet and for Ingress proxies with tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation (because they currently forward all cluster traffic to their respective backends).

For now, though, it just always returns the temporary health.Global value. That permits incremental plumbing over a number of changes. When the second to last health.Global reference is gone, then the tsd.System.HealthTracker implementation can return a private Tracker. The primary plumbing this does is adding it to LocalBackend and its dozen and change health calls. A few misc other callers are also plumbed.

Containerboot will periodically (every 10 minutes) attempt to resolve the DNS name and ensure that all traffic sent to the node's tailnet IP gets forwarded to the resolved backend IP addresses. Currently: - if the firewall mode is iptables, traffic will be load balanced accross the backend IP addresses using round robin. There are no health checks for whether the IPs are reachable. - if the firewall mode is nftables traffic will only be forwarded to the first IP address in the list. This is to be improved. * cmd/k8s-operator: support ExternalName Services Adds support for exposing endpoints, accessible from within a cluster to the tailnet via DNS names using ExternalName Services. This can be done by annotating the ExternalName Service with tailscale.com/expose: "true" annotation.
