Tom DNetto	9dee6adfab	cmd/tailscaled,ipn/ipnlocal,wgengine/...: pass dns.Manager into netstack ... Needed for a following commit which moves magicDNS handling into netstack. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
Maisem Ali	3012a2e1ca	ssh/tailssh,ipn/ipnlocal: terminate any active sessions on `up --ssh=false` ... Currently the ssh session isn't terminated cleanly, instead the packets are just are no longer routed to the in-proc SSH server. This makes it so that clients get a disconnection when the `RunSSH` pref changes to `false`. Updates #3802 Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Mihai Parparita	2ec371fe8b	ipn: remove FakeExpireAfter Backend function ... No callers remain (last one was removed with tailscale/corp@1c095ae08f), and it's pretty esoteric. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	3 years ago
Mihai Parparita	316523cc1e	ipn: remove enforceDefaults option from PrefsFromBytes ... The Mac client was using it, but it had the effect of the `RouteAll` ("Use Tailscale subnets") pref always being enabled at startup, regardless of the persisted value. enforceDefaults was added to handle cases from ~2 years ago where we ended up with persisted `"RouteAll": false` values in the keychain, but that should no longer be a concern. New users will get the default of it being enabled via `NewPrefs`. There will be a corresponding Mac client change to stop passing in enforceDefaults.

Brad Fitzpatrick	7a097ccc83	ipn/ipnlocal: close peerapi listeners on LocalBackend.Shutdown ... For tests. Now that we can always listen (whereas we used to fail prior to a2c330c496), some goroutine leak checks were failing in tests in another repo after that change.

Brad Fitzpatrick	a2c330c496	ipn/ipnlocal: use the fake peerapi listener as fallback if netstack available ... The previous commit (1b89662eff) this for Android, but we can also use this on any platform if we we would otherwise fail.

Brad Fitzpatrick	1b89662eff	ipn/ipnlocal: make peerapi listener on Android avoid the kernel ... We intercept the peerapi port in netstack anyway, so there's no reason the linux kernel on Android needs to know about it. It's only getting in the way and causing problems for reasons we don't fully understand. But we don't even need to understand it because it's not relevant anymore. Instead, provide a dummy net.Listener that just sits and blocks to pacify the rest of the code that assumes it can be stuck in a Listener.Accept call and call Listener.Close and Listener.Addr. We'll likely do this for all platforms in the future, if/when we also link in netstack on iOS.

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	8ee044ea4a	ssh/tailssh: make the SSH server a singleton, register with LocalBackend ...

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.
