That can be much shorter.
Also add a fast exit path to the concurrency on match. Doing 5 all at
once is still pretty gratuitous, though.

net/captivedetection: set Timeout on net.Dialer (#13613)
Updates tailscale/tailscale#1634 Updates tailscale/tailscale#13265 Captive portal detection uses a custom `net.Dialer` in its `http.Client`. This custom Dialer ensures that the socket is bound specifically to the Wi-Fi interface. This is crucial because without it, if any default routes are set, the outgoing requests for detecting a captive portal would bypass Wi-Fi and go through the default route instead. The Dialer did not have a Timeout property configured, so the default system timeout was applied. This caused issues in #13265, where we attempted to make captive portal detection requests over an IPsec interface used for Wi-Fi Calling. The call to `connect()` would fail and remain blocked until the system timeout (approximately 1 minute) was reached. In #13598, I simply excluded the IPsec interface from captive portal detection. This was a quick and safe mitigation for the issue. This PR is a follow-up to make the process more robust, by setting a 3 seconds timeout on any connection establishment on any interface (this is the same timeout interval we were already setting on the HTTP client).

net/captivedetection: exclude ipsec interfaces from captive portal detection (#13598)
Updates tailscale/tailscale#1634 Logs from some iOS users indicate that we're pointlessly performing captive portal detection on certain interfaces named ipsec*. These are tunnels with the cellular carrier that do not offer Internet access, and are only used to provide internet calling functionality (VoLTE / VoWiFi). ``` attempting to do captive portal detection on interface ipsec1 attempting to do captive portal detection on interface ipsec6 ``` This PR excludes interfaces with the `ipsec` prefix from captive portal detection.

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.

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> |
