Brad Fitzpatrick	4007601f73	cmd/controlclient: wire up PingRequest peerapi pings too Updates tailscale/corp#754 Change-Id: I61ac3fc44783b54bd02455bcb0baf19159b7a9d2 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	fbc079d82d	ipn/ipnlocal: prevent attempting to run SSH on Synology for now On DSM7 as a non-root user it'll run into problems. And we haven't tested on DSM6, even though it might work, but I doubt it.

Brad Fitzpatrick	a9b4bf1535	ipn/ipnserver, cmd/tailscaled: fix peerapi on Windows We weren't wiring up netstack.Impl to the LocalBackend in some cases on Windows. This fixes Windows 7 when run as a service.

Maisem Ali	7cd8c3e839	ssh/tailssh: terminate sessions when tailscaled shutsdown Ideally we would re-establish these sessions when tailscaled comes back up, however we do not do that yet so this is better than leaking the sessions.

Brad Fitzpatrick	da601c23e1	ipn/ipnlocal: add missing place where we set the SSH atomic This fixes the "tailscale up --authkey=... --ssh" path (or any "up" path that used Start instead of EditPrefs) which wasn't setting the bit.

Maisem Ali	c60cbca371	control/controlclient: store netinfo and hostinfo separately Currently, when SetNetInfo is called it sets the value on hostinfo.NetInfo. However, when SetHostInfo is called it overwrites the hostinfo field which may mean it also clears out the NetInfo it had just received. This commit stores NetInfo separately and combines it into Hostinfo as needed so that control is always notified of the latest values. Also, remove unused copies of Hostinfo from ipn.Status and controlclient.Auto. Updates #tailscale/corp#4824 (maybe fixes) Signed-off-by: Maisem Ali <maisem@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.

Maisem Ali	5a1ef1bbb9	net/tsdial: add SystemDial as a wrapper on netns.Dial The connections returned from SystemDial are automatically closed when there is a major link change.

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	e96dd00652	ipn/ipnlocal: add capability for debugging peers over peerapi The default is still users can debug their own nodes. But like `cd916b728b` did, this adds support for admins to grant additional capabilities with the new tailcfg.CapabilityDebugPeer cap.

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" ....
