apenwarr 5b06c50669 Bug report template: remove empty 'title' field.
Mysteriously, GitHub can't parse it if it's an empty string rather than
just missing.

Avery Pennarun 9c3ae750da Bug template: remove "[Bug]: " prefix for the common case.
Also shorten "[FR]:" to "FR:" to save precious subject line space.

I don't mind a prefix to distinguish feature requests, but the majority
of cases are bugs. Let's preserve as many chars as possible for the
specific topic when looking at subject lines in gmail.

(Now, if only it wouldn't include [tailscale/tailscale] on every
message...)

Smitty b382161fe5 tsdns: don't forward transient DNS errors
When a DNS server claims to be unable or unwilling to handle a request,
instead of passing that refusal along to the client, just treat it as
any other error trying to connect to the DNS server. This prevents DNS
requests from failing based on if a server can respond with a transient
error before another server is able to give an actual response. DNS
requests only failing *sometimes* is really hard to find the cause of
(#1033).

Avery Pennarun 0d4a0bf60e magicsock: if STUN failed to send before, rebind before STUNning again.
On iOS (and possibly other platforms), sometimes our UDP socket would
get stuck in a state where it was bound to an invalid interface (or no
interface) after a network reconfiguration. We can detect this by
actually checking the error codes from sending our STUN packets.

If we completely fail to send any STUN packets, we know something is
very broken. So on the next STUN attempt, let's rebind the UDP socket
to try to correct any problems.

This fixes a problem where iOS would sometimes get stuck using DERP
instead of direct connections until the backend was restarted.

Fixes #2994

Brad Fitzpatrick 7cf8ec8108 net/tlsdial: bake in LetsEncrypt's ISRG Root X1 root
We still try the host's x509 roots first, but if that fails (like if
the host is old), we fall back to using LetsEncrypt's root and
retrying with that.

tlsdial was used in the three main places: logs, control, DERP. But it
was missing in dnsfallback. So added it there too, so we can run fine
now on a machine with no DNS config and no root CAs configured.

Also, move SSLKEYLOGFILE support out of DERP. tlsdial is the logical place
for that support.

Brad Fitzpatrick 3618e8d8ac cmd/tailscaled: rename outbound HTTP proxy flag
The old name invited confusion:

* is this the HTTP proxy to use ourselves? (no, that's
  via an environment variable, per proxy conventions)
* is this for LetsEncrypt https-to-localhost-http
  proxying? (no, that'll come later)

So rename to super verbose --outbound-http-proxy-listen
before the 1.16.0 release to make it clear what it is.
It listens (serves) and it's for outbound, not inbound.

Aaron Klotz e016eaf410 cmd/tailscaled: conditionally flush Windows DNS cache on SessionChange
For the service, all we need to do is handle the `svc.SessionChange` command.
Upon receipt of a `windows.WTS_SESSION_UNLOCK` event, we fire off a goroutine to flush the DNS cache.
(Windows expects responses to service requests to be quick, so we don't want to do that synchronously.)

This is gated on an integral registry value named `FlushDNSOnSessionUnlock`,
whose value we obtain during service initialization.

(See [this link](https://docs.microsoft.com/en-us/windows/win32/api/winsvc/nc-winsvc-lphandler_function_ex) for information re: handling `SERVICE_CONTROL_SESSIONCHANGE`.)
