Nick Khyl	f23932bd98	net/dns/resolver: log forwarded query details when TS_DEBUG_DNS_FORWARD_SEND is enabled ... Troubleshooting DNS resolution issues often requires additional information.

Andrew Lytvynov	c0c4791ce7	cmd/gitops-pusher: ignore previous etag if local acls match control (#13068) ... In a situation when manual edits are made on the admin panel, around the GitOps process, the pusher will be stuck if `--fail-on-manual-edits` is set, as expected. To recover from this, there are 2 options: 1. revert the admin panel changes to get back in sync with the code 2. check in the manual edits to code The former will work well, since previous and local ETags will match control ETag again. The latter will still fail, since local and control ETags match, but previous does not. For this situation, check the local ETag against control first and ignore previous when things are already in sync.

Andrew Lytvynov	ad038f4046	cmd/gitops-pusher: add --fail-on-manual-edits flag (#13066) ... For cases where users want to be extra careful about not overwriting manual changes, add a flag to hard-fail. 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	a93dc6cdb1	wgengine/magicsock: refactor batchingUDPConn to batchingConn interface (#13042) ... This commit adds a batchingConn interface, and renames batchingUDPConn to linuxBatchingConn. tryUpgradeToBatchingConn() may return a platform- specific implementation of batchingConn.

Jordan Whited	d9d9d525d9	wgengine/netstack: increase gVisor's TCP send and receive buffer sizes (#12994) ... This commit increases gVisor's TCP max send (4->6MiB) and receive (4->8MiB) buffer sizes on all platforms except iOS. These values are biased towards higher throughput on high bandwidth-delay product paths. The iperf3 results below demonstrate the effect of this commit between two Linux computers with i5-12400 CPUs. 100ms of RTT latency is introduced via Linux's traffic control network emulator queue discipline.

Andrea Gottardo	4055b63b9b	net/captivedetection: exclude cellular data interfaces (#13002) ... Updates tailscale/tailscale#1634 This PR optimizes captive portal detection on Android and iOS by excluding cellular data interfaces (`pdp*` and `rmnet`). As cellular networks do not present captive portals, frequent network switches between Wi-Fi and cellular would otherwise trigger captive detection unnecessarily, causing battery drain.

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.

Aaron Klotz	655b4f8fc5	net/netns: remove some logspam by avoiding logging parse errors due to unspecified addresses ... I updated the address parsing stuff to return a specific error for unspecified hosts passed as empty strings, and look for that when logging errors. I explicitly did not make parseAddress return a netip.Addr containing an unspecified address because at this layer, in the absence of any host, we don't necessarily know the address family we're dealing with. For the purposes of this code I think this is fine, at least until we implement #12588. Fixes #12979 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	4 months ago

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>	4 months ago
