Brad Fitzpatrick	bcc47d91ca	cmd/tailscale/cli: use new Go 1.23 slices.Sorted And a grammatical nit. Updates #12912 Change-Id: I9feae53beb4d28dfe98b583373e2e0a43c801fc4 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago
Andrea Gottardo	d060b3fa02	cli: implement `tailscale dns status` (#13353 ) Updates tailscale/tailscale#13326 This PR begins implementing a `tailscale dns` command group in the Tailscale CLI. It provides an initial implementation of `tailscale dns status` which dumps the state of the internal DNS forwarder. Two new endpoints were added in LocalAPI to support the CLI functionality: - `/netmap`: dumps a copy of the last received network map (because the CLI shouldn't have to listen to the ipn bus for a copy) - `/dns-osconfig`: dumps the OS DNS configuration (this will be very handy for the UI clients as well, as they currently do not display this information) My plan is to implement other subcommands mentioned in tailscale/tailscale#13326, such as `query`, in later PRs.

Irbe Krumina	8e1c00f841	cmd/k8s-operator,k8s-operator/sessionrecording: ensure recording header contains terminal size for terminal sessions (#12965 ) * cmd/k8s-operator,k8s-operator/sessonrecording: ensure CastHeader contains terminal size For tsrecorder to be able to play session recordings, the recording's CastHeader must have '.Width' and '.Height' fields set to non-zero. Kubectl (or whoever is the client that initiates the 'kubectl exec' session recording) sends the terminal dimensions in a resize message that the API server proxy can intercept, however that races with the first server message that we need to record. This PR ensures we wait for the terminal dimensions to be processed from the first resize message before any other data is sent, so that for all sessions with terminal attached, the header of the session recording contains the terminal dimensions and the recording can be played by tsrecorder.

Nick Khyl	961ee321e8	ipn/{ipnauth,ipnlocal,ipnserver,localapi}: start baby step toward moving access checks from the localapi.Handler to the LocalBackend Currently, we use PermitRead/PermitWrite/PermitCert permission flags to determine which operations are allowed for a LocalAPI client. These checks are performed when localapi.Handler handles a request. Additionally, certain operations (e.g., changing the serve config) requires the connected user to be a local admin. This approach is inherently racey and is subject to TOCTOU issues. We consider it to be more critical on Windows environments, which are inherently multi-user, and therefore we prevent more than one OS user from connecting and utilizing the LocalBackend at the same time. However, the same type of issues is also applicable to other platforms when switching between profiles that have different OperatorUser values in ipn.Prefs. We'd like to allow more than one Windows user to connect, but limit what they can see and do based on their access rights on the device (e.g., an local admin or not) and to the currently active LoginProfile (e.g., owner/operator or not), while preventing TOCTOU issues on Windows and other platforms. Therefore, we'd like to pass an actor from the LocalAPI to the LocalBackend to represent the user performing the operation. The LocalBackend, or the profileManager down the line, will then check the actor's access rights to perform a given operation on the device and against the current (and/or the target) profile. This PR does not change the current permission model in any way, but it introduces the concept of an actor and includes some preparatory work to pass it around. Temporarily, the ipnauth.Actor interface has methods like IsLocalSystem and IsLocalAdmin, which are only relevant to the current permission model. It also lacks methods that will actually be used in the new model. We'll be adding these gradually in the next PRs and removing the deprecated methods and the Permit* flags at the end of the transition.

Nick Khyl	03acab2639	cmd/cloner, cmd/viewer, util/codegen: add support for aliases of cloneable types We have several checked type assertions to types.Named in both cmd/cloner and cmd/viewer. As Go 1.23 updates the go/types package to produce Alias type nodes for type aliases, these type assertions no longer work as expected unless the new behavior is disabled with gotypesalias=0. In this PR, we add codegen.NamedTypeOf(t types.Type), which functions like t.(types.Named) but also unrolls type aliases. We then use it in place of type assertions in the cmd/cloner and cmd/viewer packages where appropriate. We also update type switches to include types.Alias alongside types.Named in relevant cases, remove *types.Struct cases when switching on types.Type.Underlying and update the tests with more cases where type aliases can be used.

Nick Khyl	a9dc6e07ad	util/codegen, cmd/cloner, cmd/viewer: update codegen.LookupMethod to support alias type nodes Go 1.23 updates the go/types package to produce Alias type nodes for type aliases, unless disabled with gotypesalias=0. This new default behavior breaks codegen.LookupMethod, which uses checked type assertions to types.Named and types.Interface, as only named types and interfaces have methods. In this PR, we update codegen.LookupMethod to perform method lookup on the right-hand side of the alias declaration and clearly switch on the supported type nodes types. We also improve support for various edge cases, such as when an alias is used as a type parameter constraint, and add tests for the LookupMethod function. Additionally, we update cmd/viewer/tests to include types with aliases used in type fields and generic type constraints.

Brad Fitzpatrick	3904e4d175	cmd/tta, tstest/natlab/vnet: remove unneeded port 124 log hack, add log buffer The natlab Test Agent (tta) still had its old log streaming hack in place where it dialed out to anything on TCP port 124 and those logs were streamed to the host running the tests. But we'd since added gokrazy syslog streaming support, which made that redundant. So remove all the port 124 stuff. And then make sure we log to stderr so gokrazy logs it to syslog. Also, keep the first 1MB of logs in memory in tta too, exported via localhost:8034/logs for interactive debugging. That was very useful during debugging when I added IPv6 support.

This lets a non-operator at least start the app and see the status, even if they can't change everything. (the web UI is unaffected by operator) A future change can add a LocalAPI call to check permissions and guide people through adding a user as an operator (perhaps the web client can do that?)

Will Norris	3c66ee3f57	cmd/systray: add a basic linux systray app This adds a systray app for linux, similar to the apps for macOS and windows. There are already a number of community-developed systray apps, but most of them are either long abandoned, are built for a specific desktop environment, or simply wrap the tailscale CLI. This uses fyne.io/systray (a fork of github.com/getlantern/systray) which uses newer D-Bus specifications to render the tray icon and menu. This results in a pretty broad support for modern desktop environments. This initial commit lacks a number of features like profile switching, device listing, and exit node selection. This is really focused on the application structure, the interaction with LocalAPI, and some system integration pieces like the app icon, notifications, and the clipboard.

Anton Tolchanov	151b77f9d6	cmd/tl-longchain: tool to re-sign nodes with long rotation signatures In Tailnet Lock, there is an implicit limit on the number of rotation signatures that can be chained before the signature becomes too long. This program helps tailnet admins to identify nodes that have signatures with long chains and prints commands to re-sign those node keys with a fresh direct signature. It's a temporary mitigation measure, and we will remove this tool as we design and implement a long-term approach for rotation signatures. Example output: ``` 2024/08/20 18:25:03 Self: does not need re-signing 2024/08/20 18:25:03 Visible peers with valid signatures: 2024/08/20 18:25:03 Peer xxx2.yy.ts.net.

Jordan Whited	df6014f1d7	net/tstun,wgengine{/netstack/gro}: refactor and re-enable gVisor GRO for Linux (#13172 ) In `2f27319baf` we disabled GRO due to a data race around concurrent calls to tstun.Wrapper.Write(). This commit refactors GRO to be thread-safe, and re-enables it on Linux. This refactor now carries a GRO type across tstun and netstack APIs with a lifetime that is scoped to a single tstun.Wrapper.Write() call. In `25f0a3fc8f` we used build tags to prevent importation of gVisor's GRO package on iOS as at the time we believed it was contributing to additional memory usage on that platform. It wasn't, so this commit simplifies and removes those build tags.

This is only useful if the etag cache is persistent or otherwise reliable. This flag should not be used in ephemeral CI workers that won't persist the cache.

Jordan Whited	f0230ce0b5	go.mod,net/tstun,wgengine/netstack: implement gVisor TCP GRO for Linux (#12921 ) This commit implements TCP GRO for packets being written to gVisor on Linux. Windows support will follow later. The wireguard-go dependency is updated in order to make use of newly exported IP checksum functions. gVisor is updated in order to make use of newly exported stack.PacketBuffer GRO logic. TCP throughput towards gVisor, i.e. TUN write direction, is dramatically improved as a result of this commit. Benchmarks show substantial improvement, sometimes as high as 2x. High bandwidth-delay product paths remain receive window limited, bottlenecked by gVisor's default TCP receive socket buffer size. This will be addressed in a follow-on commit. The iperf3 results below demonstrate the effect of this commit between two Linux computers with i5-12400 CPUs. There is roughly ~13us of round trip latency between them. The first result is from commit `57856fc` without TCP GRO. Starting Test: protocol: TCP, 1 streams, 131072 byte blocks - - - - - - - - - - - - - - - - - - - - - - - - - Test Complete.

Jordan Whited	7bc2ddaedc	go.mod,net/tstun,wgengine/netstack: implement gVisor TCP GSO for Linux (#12869 ) This commit implements TCP GSO for packets being read from gVisor on Linux. Windows support will follow later. The wireguard-go dependency is updated in order to make use of newly exported GSO logic from its tun package. A new gVisor stack.LinkEndpoint implementation has been established (linkEndpoint) that is loosely modeled after its predecessor (channel.Endpoint). This new implementation supports GSO of monster TCP segments up to 64K in size, whereas channel.Endpoint only supports up to 32K. linkEndpoint will also be required for GRO, which will be implemented in a follow-on commit. TCP throughput from gVisor, i.e. TUN read direction, is dramatically improved as a result of this commit. Benchmarks show substantial improvement through a wide range of RTT and loss conditions, sometimes as high as 5x. The iperf3 results below demonstrate the effect of this commit between two Linux computers with i5-12400 CPUs. There is roughly ~13us of round trip latency between them.

Note that even with `PreferDualStack` set, testing a dual-stack GKE cluster with the default DNS setup of kube-dns did not correctly set both A and AAAA records for the headless service, and instead only did so when switching the cluster DNS to Cloud DNS. For both IPv4 and IPv6 to work simultaneously in a dual-stack cluster, we require headless services to return both A and AAAA records. If the host doesn't support IPv6 but the FQDN specified only has IPv6 addresses available, containerboot will exit with error code 1 and an error message because there is no viable egress route.
