Brad Fitzpatrick	58abae1f83	net/dns/{publicdns,resolver}: add NextDNS DoH support NextDNS is unique in that users create accounts and then get user-specific DNS IPs & DoH URLs. For DoH, the customer ID is in the URL path. For IPv6, the IP address includes the customer ID in the lower bits. For IPv4, there's a fragile "IP linking" mechanism to associate your public IPv4 with an assigned NextDNS IPv4 and that tuple maps to your customer ID. We don't use the IP linking mechanism. Instead, NextDNS is DoH-only. Which means using NextDNS necessarily shunts all DNS traffic through 100.100.100.100 (programming the OS to use 100.100.100.100 as the global resolver) because operating systems can't usually do DoH themselves. Once it's in Tailscale's DoH client, we then connect out to the known NextDNS IPv4/IPv6 anycast addresses. If the control plane sends the client a NextDNS IPv6 address, we then map it to the corresponding NextDNS DoH with the same client ID, and we dial that DoH server using the combination of v4/v6 anycast IPs.

Mihai Parparita	01e6565e8a	cmd/tsconnect: temporarily switch to xterm.js fork that handles popup windows Allows other work to be unblocked while xtermjs/xterm.js#4069 is worked through. To enable testing the popup window handling, the standalone app allows opening of SSH sessions in new windows by holding down the alt key while pressing the SSH button.

Brad Fitzpatrick	ad7546fb9f	tailcfg: fix broken test from comment change Fix broken build from `255c0472fb` "Oh, that's safe to commit because most tests are passing and it's just a comment change!", I thought, forgetting I'd added a test that parses its comments.

Brad Fitzpatrick	255c0472fb	tailcfg: reformat CurrentCapabilityVersion to be a bulleted list gofmt in 1.19 is now opinionated about structured text formatting in comments. It did not like our style and kept fighting us whenever we changed these lines. Give up the fight and be a bulleted list for it.

Andrew Dunham	9240f5c1e2	wgengine/netstack: only accept connection after dialing (#5503 ) If we accept a forwarded TCP connection before dialing, we can erroneously signal to a client that we support IPv6 (or IPv4) without that actually being possible. Instead, we only complete the client's TCP handshake after we've dialed the outbound connection; if that fails, we respond with a RST. Updates #5425 (maybe fixes!)

Mihai Parparita	2f702b150e	cmd/tsconnect: add dev-pkg command for two-sided development Allows imports of the NPM package added by `1a093ef482` to be replaced with import("http://localhost:9090/pkg/pkg.js"), so that changes can be made in parallel to both the module and code that uses it (without any need for NPM publishing or even building of the package).

James Tucker	672c2c8de8	wgengine/magicsock: add filter to ignore disco to old/other ports Incoming disco packets are now dropped unless they match one of the current bound ports, or have a zero port. The BPF filter passes all packets with a disco header to the raw packet sockets regardless of destination port (in order to avoid needing to reconfigure BPF on rebind). If a BPF enabled node has just rebound, due to restart or rebind, it may receive and reply to disco ping packets destined for ports other than those which are presently bound. If the pong is accepted, the pinging node will now assume that it can send WireGuard traffic to the pinged port - such traffic will not reach the node as it is not destined for a bound port. The zero port is ignored, if received. This is a speculative defense and would indicate a problem in the receive path, or the BPF filter. This condition is allowed to pass as it may enable traffic to flow, however it will also enable problems with the same symptoms this patch otherwise fixes.

James Tucker	be140add75	wgengine/magicsock: fix regression in initial bind for js `1f959edeb0` introduced a regression for JS where the initial bind no longer occurred at all for JS.

James Tucker	1f959edeb0	wgengine/magicksock: remove nullability of RebindingUDPConns Both RebindingUDPConns now always exist. the initial bind (which now just calls rebind) now ensures that bind is called for both, such that they both at least contain a blockForeverConn.

Andrew Dunham	b8596f2a2f	net/dnsfallback: cache most recent DERP map on disk (#5545 ) This is especially helpful as we launch newer DERPs over time, and older clients have progressively out-of-date static DERP maps baked in. After this, as long as the client has successfully connected once, it'll cache the most recent DERP map it knows about.

Maisem Ali	060ecb010f	docs/k8s: make run.sh handle SIGINT It was previously using jobcontrol to achieve this, but that apparently doesn't work when there is no tty.
