Brad Fitzpatrick	1e2e319e7d	util/slicesx: add MapKeys and MapValues from golang.org/x/exp/maps Importing the ~deprecated golang.org/x/exp/maps as "xmaps" to not shadow the std "maps" was getting ugly. And using slices.Collect on an iterator is verbose & allocates more. So copy (x)maps.Keys+Values into our slicesx package instead.

James Tucker	aa04f61d5e	net/netcheck: adjust HTTPS latency check to connection time and avoid data race The go-httpstat package has a data race when used with connections that are performing happy-eyeballs connection setups as we are in the DERP client. There is a long-stale PR upstream to address this, however revisiting the purpose of this code suggests we don't really need httpstat here. The code populates a latency table that may be used to compare to STUN latency, which is a lightweight RTT check. Switching out the reported timing here to simply the request HTTP request RTT avoids the problematic package.

Brad Fitzpatrick	c3306bfd15	control/controlhttp/controlhttpserver: split out Accept to its own package Otherwise all the clients only using control/controlhttp for the ts2021 HTTP client were also pulling in WebSocket libraries, as the server side always needs to speak websockets, but only GOOS=js clients speak it. This doesn't yet totally remove the websocket dependency on Linux because Linux has a envknob opt-in to act like GOOS=js for manual testing and force the use of WebSockets for DERP only (not control). We can put that behind a build tag in a future change to eliminate the dep on all GOOSes.

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.

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.

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.

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.

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.

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.

Joe Tsai	85febda86d	all: use zstdframe where sensible (#11491 ) Use the zstdframe package where sensible instead of plumbing around our own zstd.Encoder just for stateless operations. This causes logtail to have a dependency on zstd, but that's arguably okay since zstd support is implicit to the protocol between a client and the logging service. Also, virtually every caller to logger.NewLogger was manually setting up a zstd.Encoder anyways, meaning that zstd was functionally always a dependency.

James Tucker	24bac27632	util/rands: add Shuffle and Perm functions with on-stack RNG state The new math/rand/v2 package includes an m-local global random number generator that can not be reseeded by the user, which is suitable for most uses without the RNG pools we have in a number of areas of the code base. The new API still does not have an allocation-free way of performing a seeded operations, due to the long term compiler bug around interface parameter escapes, and the Source interface. This change introduces the two APIs that math/rand/v2 can not yet replace efficiently: seeded Perm() and Shuffle() operations. This implementation chooses to use the PCG random source from math/rand/v2, as with sufficient compiler optimization, this source should boil down to only two on-stack registers for random state under ideal conditions.

This will be used to run the new full management web client, which will only be accessible over Tailscale (with an extra auth check step over noise) from the daemon. This switch also allows us to run the web interface as a long-lived service in environments where the CLI version is restricted to CGI, allowing us to manage certain auth state in memory. ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for ios builds to satisfy ios restriction from adding "text/template" and "html/template" dependencies.

Aaron Klotz	95671b71a6	ipn, safesocket: use Windows token in LocalAPI On Windows, the idiomatic way to check access on a named pipe is for the server to impersonate the client on its current OS thread, perform access checks using the client's access token, and then revert the OS thread's access token back to its true self. The access token is a better representation of the client's rights than just a username/userid check, as it represents the client's effective rights at connection time, which might differ from their normal rights. This patch updates safesocket to do the aforementioned impersonation, extract the token handle, and then revert the impersonation. We retain the token handle for the remaining duration of the connection (the token continues to be valid even after we have reverted back to self). Since the token is a property of the connection, I changed ipnauth to wrap the concrete net.Conn to include the token. I then plumbed that change through ipnlocal, ipnserver, and localapi as necessary. I also added a PermitLocalAdmin flag to the localapi Handler which I intend to use for controlling access to a few new localapi endpoints intended for configuring auto-update.
