Brad Fitzpatrick	cc575fe4d6	net/dns: schedule DoH upgrade explicitly, fix Resolver.Addr confusion Two changes in one: * make DoH upgrades an explicitly scheduled send earlier, when we come up with the resolvers-and-delay send plan. Previously we were getting e.g. four Google DNS IPs and then spreading them out in time (for back when we only did UDP) but then later we added DoH upgrading at the UDP packet layer, which resulted in sometimes multiple DoH queries to the same provider running (each doing happy eyeballs dialing to 4x IPs themselves) for each of the 4 source IPs. Instead, take those 4 Google/Cloudflare IPs and schedule 5 things: first the DoH query (which can use all 4 IPs), and then each of the 4 IPs as UDP later. * clean up the dnstype.Resolver.Addr confusion; half the code was using it as an IP string (as documented) as half was using it as an IP:port (from some prior type we used), primarily for tests. Instead, document it was being primarily an IP string but also accepting an IP:port for tests, then add an accessor method on it to get the IPPort and use that consistently everywhere.

Brad Fitzpatrick	e96dd00652	ipn/ipnlocal: add capability for debugging peers over peerapi The default is still users can debug their own nodes.

Brad Fitzpatrick	8ee044ea4a	ssh/tailssh: make the SSH server a singleton, register with LocalBackend Remove the weird netstack -> tailssh dependency and instead have tailssh register itself with ipnlocal when linked.

Maisem Ali	50b4b8b2c6	ipn/ipnlocal: make peerIPs return a sorted slice Currently peerIPs doesn't do any sorting of the routes it returns. This is typically fine, however imagine the case of an HA subnet router failover. When a route R moves from peer A to peer B, the output of peerIPs changes. This in turn causes all the deephash check inside wgengine to fail as the hashed value of [R1, R2] is different than the hashed value of [R2, R1]. When the hash check failes, it causes wgengine to reconfigure all routes in the OS. This is especially problematic for macOS and iOS where we use the NetworkExtension. This commit makes it that the peerIPs are always sorted when returned, thus making the hash be consistent as long as the list of routes remains static.

Brad Fitzpatrick	3ae701f0eb	net/tsaddr, wgengine/netstack: add IPv6 range that forwards to site-relative IPv4 This defines a new magic IPv6 prefix, fd7a:115c:a1e0:b1a::/64, a subset of our existing /48, where the final 32 bits are an IPv4 address, and the middle 32 bits are a user-chosen "site ID". (which must currently be 0000:00xx; the top 3 bytes must be zero for now) e.g., I can say my home LAN's "site ID" is "0000:00bb" and then advertise its 10.2.0.0/16 IPv4 range via IPv6, like: tailscale up --advertise-routes=fd7a:115c:a1e0:b1a::bb:10.2.0.0/112 (112 being /128 minuse the /96 v6 prefix length) Then people in my tailnet can: $ curl '[fd7a:115c:a1e0:b1a::bb:10.2.0.230]' <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ....

Maisem Ali	6fecc16c3b	ipn/ipnlocal: do not process old status messages received out of order When `setWgengineStatus` is invoked concurrently from multiple goroutines, it is possible that the call invoked with a newer status is processed before a call with an older status. e.g. a status that has endpoints might be followed by a status without endpoints. This causes unnecessary work in the engine and can result in packet loss. This patch adds an `AsOf time.Time` field to the status to specifiy when the status was calculated, which later allows `setWgengineStatus` to ignore any status messages it receives that are older than the one it has already processed.

Brad Fitzpatrick	d5f8f38ac6	tailcfg: rename map request version to "capability version" And add a CapabilityVersion type, primarily for documentation. This makes MapRequest.Version, RegisterRequest.Version, and SetDNSRequest.Version all use the same version, which will avoid confusing in the future if Register or SetDNS ever changed their semantics on Version change. (Currently they're both always 1) This will requre a control server change to allow a SetDNSRequest.Version value other than 1 to be deployed first.

Brad Fitzpatrick	bb94561c96	net/netutil: fix regression where peerapi would get closed after 1st req I introduced a bug in `8fe503057d` when unifying oneConnListener implementations. The NewOneConnListenerFrom API was easy to misuse (its Close method closes the underlying Listener), and we did (via http.Serve, which closes the listener after use, which meant we were close the peerapi's listener, even though we only wanted its Addr) Instead, combine those two constructors into one and pass in the Addr explicitly, without delegating through to any Listener.
