David Anderson	25ce9885a2	net/dns: don't use NM+resolved for NM >=1.26.6. NetworkManager fixed the bug that forced us to use NetworkManager if it's programming systemd-resolved, and in the same release also made NetworkManager ignore DNS settings provided for unmanaged interfaces... Which breaks what we used to do. So, with versions 1.26.6 and above, we MUST NOT use NetworkManager to indirectly program systemd-resolved, but thankfully we can talk to resolved directly and get the right outcome.

Josh Bleecher Snyder	8d7f7fc7ce	health, wgenegine: fix receive func health checks yet again The existing implementation was completely, embarrassingly conceptually broken. We aren't able to see whether wireguard-go's receive function goroutines are running or not. All we can do is model that based on what we have done. This commit fixes that model.

Josh Bleecher Snyder	5835a3f553	health, wgengine/magicsock: avoid receive function false positives Avery reported a sub-ms health transition from "receiveIPv4 not running" to "ok". To avoid these transient false-positives, be more precise about the expected lifetime of receive funcs. The problematic case is one in which they were started but exited prior to a call to connBind.Close. Explicitly represent started vs running state, taking care with the order of updates.

Brad Fitzpatrick	e40e5429c2	cmd/tailscale/cli: make 'tailscale up' protect --advertise-exit-node removal The new "tailscale up" checks previously didn't protect against --advertise-exit-node being omitted in the case that --advertise-routes was also provided. It wasn't done before because there is no corresponding pref for "--advertise-exit-node"; it's a helper flag that augments --advertise-routes. But that's an implementation detail and we can still help users. We just have to special case that pref and look whether the current routes include both the v4 and v6 /0 routes.

Josh Bleecher Snyder	a29b0cf55f	wgengine/wglog: allow wireguard-go receive routines to log I've spent two days searching for a theoretical wireguard-go bug around receive functions exiting early. I've found many bugs, but none of the flavor we're looking for. Restore wireguard-go's logging around starting and stopping receive functions, so that we can definitively rule in or out this particular theory.

Brad Fitzpatrick	91c9c33036	cmd/tailscaled: don't block ipnserver startup behind engine init on Windows With this change, the ipnserver's safesocket.Listen (the localhost tcp.Listen) happens right away, before any synchronous TUN/DNS/Engine/etc setup work, which might be slow, especially on early boot on Windows. Because the safesocket.Listen starts up early, that means localhost TCP dials (the safesocket.Connect from the GUI) complete successfully and thus the GUI avoids the MessageBox error. (I verified that pacifies it, even without a Listener.Accept; I'd feared that Windows localhost was maybe special and avoided the normal listener backlog). Once the GUI can then connect immediately without errors, the various timeouts then matter less, because the backend is no longer trying to race against the GUI's timeout. So keep retrying on errors for a minute, or 10 minutes if the system just booted in the past 10 minutes. This should fix the problem with Windows 10 desktops auto-logging in and starting the Tailscale frontend which was then showing a MessageBox error about failing to connect to tailscaled, which was slow coming up because the Windows networking stack wasn't up yet. Fingers crossed. Fixes #1313 (previously #1187, etc) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

David Anderson	6fd9e28bd0	ipn/ipnlocal: add arpa suffixes to MagicDNS for reverse lookups. This used to not be necessary, because MagicDNS always did full proxying. But with split DNS, we need to know which names to route to our resolver, otherwise reverse lookups break. This captures the entire CGNAT range, as well as our Tailscale ULA.

Brad Fitzpatrick	f99e63bb17	ipn: don't Logout when Windows GUI disconnects Logout used to be a no-op, so the ipnserver previously synthensized a Logout on disconnect. Now that Logout actually invalidates the node key that was forcing all GUI closes to log people out. Instead, add a method to LocalBackend to specifically mean "the Windows GUI closed, please forget all the state".
