Brad Fitzpatrick	01bd789c26	ipn/ipnserver: add Server.LocalBackend accessor Was done as part of `e6fbc0cd54` for ssh work, but wasn't committed yet. Including it here both to minimize the ssh diff size, and because I need it for a separate change.

Brad Fitzpatrick	e6fbc0cd54	cmd/tailscaled, ipn/ipnserver: refactor ipnserver More work towards removing the massive ipnserver.Run and ipnserver.Options and making composable pieces. Work remains. (The getEngine retry loop on Windows complicates things.) For now some duplicate code exists. Once the Windows side is fixed to either not need the retry loop or to move the retry loop into a custom wgengine.Engine wrapper, then we can unify tailscaled_windows.go too.

Brad Fitzpatrick	c7bff35fee	ipn/ipnlocal: add owner-only debug handler to get process env For debugging Synology. Like the existing goroutines handler, in that it's owner-only. Change-Id: I852f0626be8e1c0b6794c1e062111d14adc3e6ac Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Josh Bleecher Snyder	c467ed0b62	wgengine/wgcfg: always close io.Pipe In DeviceConfig, we did not close r after calling FromUAPI. If FromUAPI returned early due to an error, then it might not have read all the data that IpcGetOperation wanted to write. As a result, IpcGetOperation could hang, as in #3220. We were also closing the wrong end of the pipe after IpcSetOperation in ReconfigDevice. To ensure that we get all available information to diagnose such a situation, include all errors anytime something goes wrong. This should fix the immediate crashing problem in #3220. We'll then need to figure out why IpcGetOperation was failing. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	3fd5f4380f	util/multierr: new package github.com/go-multierror/multierror served us well. But we need a few feature from it (implement Is), and it's not worth maintaining a fork of such a small module. Instead, I did a clean room implementation inspired by its API.
