Brad Fitzpatrick	db85384f9c	cmd/tailscaled: default to userspace-networking mode on gokrazy, set paths One of the current few steps to run Tailscale on gokrazy is to specify the --tun=userspace-networking flag: https://gokrazy.org/userguide/install/tailscale/ Instead, make it the default for now. Later we can change the default to kernel mode if available and fall back to userspace mode like Synology, once #391 is done. Likewise, set default paths for Gokrazy, as its filesystem hierarchy is not the Linux standard one. Instead, use the conventional paths as documented at https://gokrazy.org/userguide/install/tailscale/.

Brad Fitzpatrick	a28d280b95	cmd/tailscaled: move start-up failure logging to one place The caller of func run said: // No need to log; the func already did But that wasn't true. Some return paths didn't log. So instead, return rich errors and have func main do the logging, so we can't miss anything in the future. Prior to this, safesocket.Listen for instance was causing tailscaled to os.Exit(1) on failure without any clue as to why.

Brad Fitzpatrick	adc5997592	net/tsdial: give netstack a Dialer, start refactoring name resolution This starts to refactor tsdial.Dialer's name resolution to have different stages: in-memory MagicDNS vs system resolution. A future change will plug in ExitDNS resolution. This also plumbs a Dialer into netstack and unexports the dnsMap internals. And it removes some of the async AddNetworkMapCallback usage and replaces it with synchronous updates of the Dialer's netmap from LocalBackend, since the LocalBackend has the Dialer too.

Brad Fitzpatrick	c37af58ea4	net/tsdial: move more weirdo dialing into new tsdial package, plumb Not done yet, but this move more of the outbound dial special casing from random packages into tsdial, which aspires to be the one unified place for all outbound dialing shenanigans. Then this plumbs it all around, so everybody is ultimately holding on to the same dialer. As of this commit, macOS/iOS using an exit node should be able to reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt to stay within the Network Extension. A number of steps remain, including but limited to: * move a bunch more random dialing stuff * make netstack-mode tailscaled be able to use exit node's DNS proxy, teaching tsdial's resolver to use it when an exit node is in use.

Brad Fitzpatrick	d5405c66b7	net/tsdial: start of new package to unify all outbound dialing complexity For now this just deletes the net/socks5/tssocks implementation (and the DNSMap stuff from wgengine/netstack) and moves it into net/tsdial. Then initialize a Dialer early in tailscaled, currently only use for the outbound and SOCKS5 proxies. It will be plumbed more later. Notably, it needs to get down into the DNS forwarder for exit node DNS forwading in netstack mode. But it will also absorb all the peerapi setsockopt and netns Dial and tlsdial complexity too.

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.

Josh Bleecher Snyder	3fd5f4380f	util/multierr: new package github.com/go-multierror/multierror served us well.

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.

Brad Fitzpatrick	a7cb241db1	cmd/tailscaled: add support for running an HTTP proxy This adds support for tailscaled to be an HTTP proxy server.

Brad Fitzpatrick	7f7a81e5ae	cmd/tailscaled: add func to create ipnserver.Opts To unify the Windows service and non-service/non-Windows paths a bit. And provides a way to make Linux act like Windows for testing. (notably, for testing the fix to #2137) One perhaps visible change of this is that tailscaled.exe when run in cmd.exe/powershell (not as a Windows Service) no longer uses the "_daemon" autostart key. But in addition to being naturally what falls out of this change, that's also what Windows users would likely want, as otherwise the unattended mode user is ignored when the "_daemon" autostart key is specified. Notably, this would let people debug what their normally-run-as-a-service tailscaled is doing, even when they're running in Unattended Mode.
