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. The first result is from commit 57856fc without TCP GSO. Starting Test: protocol: TCP, 1 streams, 131072 byte blocks - - - - - - - - - - - - - - - - - - - - - - - - - Test Complete.

Andrea Gottardo	949b15d858	net/captivedetection: call SetHealthy once connectivity restored (#12974) ... Fixes tailscale/tailscale#12973 Updates tailscale/tailscale#1634 There was a logic issue in the captive detection code we shipped in https://github.com/tailscale/tailscale/pull/12707. Assume a captive portal has been detected, and the user notified. Upon switching to another Wi-Fi that does *not* have a captive portal, we were issuing a signal to interrupt any pending captive detection attempt. However, we were not also setting the `captive-portal-detected` warnable to healthy. The result was that any "captive portal detected" alert would not be cleared from the UI. Also fixes a broken log statement value. Signed-off-by: Andrea Gottardo <andrea@gottardo.me>	2 months ago

Irbe Krumina	57856fc0d5	ipn,wgengine/magicsock: allow setting static node endpoints via tailscaled configfile (#12882) ... wgengine/magicsock,ipn: allow setting static node endpoints via tailscaled config file. Adds a new StaticEndpoints field to tailscaled config that can be used to statically configure the endpoints that the node advertizes. This field will replace TS_DEBUG_PRETENDPOINTS env var that can be used to achieve the same. Additionally adds some functionality that ensures that endpoints are updated when configfile is reloaded. Also, refactor configuring/reconfiguring components to use the same functionality when configfile is parsed the first time or subsequent times (after reload). Previously a configfile reload did not result in resetting of prefs. Now it does- but does not yet tell the relevant components to consume the new prefs. This is to be done in a follow-up.

Nick Khyl	1608831c33	wgengine/router: use quad-100 as the nexthop on Windows ... Windows requires routes to have a nexthop. Routes created using the interface's local IP address or an unspecified IP address ("0.0.0.0" or "::") as the nexthop are considered on-link routes. Notably, Windows treats on-link subnet routes differently, reserving the last IP in the range as the broadcast IP and therefore prohibiting TCP connections to it, resulting in WSA error 10049: "The requested address is not valid in its context. This does not happen with single-host routes, such as routes to Tailscale IP addresses, but becomes a problem with advertised subnets when all IPs in the range should be reachable. Before Windows 8, only routes created with an unspecified IP address were considered on-link, so our previous approach of using the interface's own IP as the nexthop likely worked on Windows 7. This PR updates configureInterface to use the TailscaleServiceIP (100.100.100.100) and its IPv6 counterpart as the nexthop for subnet routes.

Paul Scott	d97cddd876	tsweb: swallow panics ... With this change, the error handling and request logging are all done in defers after calling inner.ServeHTTP.

Which if you're using StdHandler there always is. We prefer this to ensure that we are able to write a 500 Internal Server Error to the client.

With this change, only the outermost StdHandler/logHandler actually logs the request or invokes OnStart or OnCompletion callbacks. The error-rendering part of retHandler lives on in errorHandler, and errorHandler passes those errors up the stack to logHandler through a callback that logHandler places in the request.Context().
