Josh Bleecher Snyder	63cd581c3f	safesocket: add ConnectionStrategy, provide control over fallbacks `fee2d9fad` added support for cmd/tailscale to connect to IPNExtension. It came in two parts: If no socket was provided, dial IPNExtension first, and also, if dialing the socket failed, fall back to IPNExtension. The second half of that support caused the integration tests to fail when run on a machine that was also running IPNExtension. The integration tests want to wait until the tailscaled instances that they spun up are listening. They do that by dialing the new instance. But when that dial failed, it was falling back to IPNExtension, so it appeared (incorrectly) that tailscaled was running. Hilarity predictably ensued. If a user (or a test) explicitly provides a socket to dial, it is a reasonable assumption that they have a specific tailscaled in mind and don't want to fall back to IPNExtension. It is certainly true of the integration tests. Instead of adding a bool to Connect, split out the notion of a connection strategy. For now, the implementation remains the same, but with the details hidden a bit. Later, we can improve that. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

David Crawshaw	e67f1b5da0	client/tailscale, cmd/tailscale/cli: plumb --socket through Without this, `tailscale status` ignores the --socket flag on macOS and always talks to the IPNExtension, even if you wanted it to inspect a userspace tailscaled.

Brad Fitzpatrick	f11cb811cc	safesocket: support finding tailscale port/auth token from sandboxed CLI Previously the CLI could only find the HTTP auth token when running the CLI outside the sandbox, not like /Applications/Tailscale.app/Contents/MacOS/Tailscale when that was from the App Store.

Brad Fitzpatrick	54d0d83b67	safesocket: on Linux, make /var/run/tailscale be 0755 Continuation of earlier two umask changes, `5611f290eb` and `d6e9fb1df0`. This change mostly affects us, running tailscaled as root by hand (wit a umask of 0077), not under systemd. End users running tailscaled under systemd won't have a umask.

Brad Fitzpatrick	5611f290eb	ipn, ipnserver: only require sudo on Linux for mutable CLI actions This partially reverts `d6e9fb1df0`, which modified the permissions on the tailscaled Unix socket and thus required "sudo tailscale" even for "tailscale status". Instead, open the permissions back up (on Linux only) but have the server look at the peer creds and only permit read-only actions unless you're root. In the future we'll also have a group that can do mutable actions. On OpenBSD and FreeBSD, the permissions on the socket remain locked down to 0600 from `d6e9fb1df0`.

David Anderson	4460bd638b	safesocket: simplify API. On unix, we want to provide a full path to the desired unix socket. On windows, currently we want to provide a TCP port, but someday we'll also provide a "path-ish" object for a named pipe. For now, simplify the API down to exactly a path and a TCP port.
