This feature wasn't working until I realized that we also need to opt into
the events. MSDN wasn't so generous as to make this easy to deduce.

A couple of gnarly assumptions in this code, as always with the async
message thing.
UI button is based on the DNS settings in the admin panel.

iOS and Android no longer use these. They both now (as of today)
use the hostinfo.SetFoo setters instead.

Turns out the iOS client has been only sending the OS version it first
started at. This whole hostinfo-via-prefs mechanism was never a good idea.
Start removing it.

This config update will let tailscale use bencher without worrying about the bencher check appearing as failed due to a benchmark regressing.

This exists purely to keep "go mod tidy" happy.

Lot of people have been hitting this.
Now it says:
$ tailscale cert tsdev.corp.ts.net
Access denied: cert access denied
Use 'sudo tailscale cert' or 'tailscale up --operator=$USER' to not require 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.

DNSSEC is an availability issue, as recently demonstrated by the
Slack issue, with limited security advantage. DoH on the other hand
is a critical security upgrade. This change adds DoH support for the
non-DNSSEC endpoints of Quad9.

It was in the wrong filter direction before, per CPU profiles
we now have.
Updates #1526 (maybe fixes? time will tell)
Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
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.

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`.)

This adds support for tailscaled to be an HTTP proxy server.
It shares the same backend dialing code as the SOCK5 server, but the
client protocol is HTTP (including CONNECT), rather than SOCKS.

This fixes "tailscale cert" on Synology where the var directory is
typically like /volume2/@appdata/Tailscale, or any other tailscaled
user who specifies a non-standard state file location.
This is a interim fix on the way to #2932.

In a56520c3c7 dependabot attempted to bump

not the self-hosted VM builder. Revert for now.

We unconditionally set appropriate perms on the statefile dir.
We look at the basename of the statefile dir, and if it is "tailscale", then
we set perms as appropriate.

Because the macOS CLI runs in the sandbox, including the filesystem,
so users would be confused that -cpu-profile=prof.cpu succeeds but doesn't
write to their current directory, but rather in some random Library/Containers
directory somewhere on the machine (which varies depending on the Mac build
type: App Store vs System Extension)

This was already possible on Linux if you ran tailscaled with --debug
(which runs net/http/pprof), but it requires the user have the Go
toolchain around.
Also, it wasn't possible on macOS, as there's no way to run the IPNExtension
with a debug server (it doesn't run tailscaled).
And on Windows it's super tedious: beyond what users want to do or
what we want to explain.
Instead, put it in "tailscale debug" so it works and works the same on
all platforms. Then we can ask users to run it when we're debugging something
and they can email us the output files.

pfSense stores its SSL certificate and key in the PHP config.
We wrote PHP code to pull the two out of the PHP config and
into environment variables before running "tailscale web".
The pfSense web UI is served over https, we need "tailscale web"
to also support https in order to put it in an <iframe>.
