Brad Fitzpatrick	f18bb6397b	cmd/tailscale: tell gokrazy to not manage the CLI as a daemon In the future we'll probably want to run the "tailscale web" server instead, but for now stop the infinite restart loop. See https://gokrazy.org/userguide/process-interface/ for details. Updates #1866 Change-Id: I4133a5fdb859b848813972620495865727fe397a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
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	4686224e5a	cmd/tailscaled: add a no-op test for profiling init-time memory allocs Turns out we're pretty good already at init-time work in tailscaled.

Aaron Klotz	e31d68d64e	hostinfo: use the sentinel value set by the MSI installer to detect MSI package type The MSI installer sets a special sentinel value that we can use to detect it. I also removed the code that bails out when the installation path is not `Program Files`, as both the NSIS and MSI installers permit the user to install to a different path.

Brad Fitzpatrick	a80cef0c13	cmd/derper: fix regression from bootstrap DNS optimization The commit `b9c92b90db` earlier today caused a regression of serving an empty map always, as it was JSON marshalling an atomic.Value instead of the DNS entries map it just built.

Joe Tsai	0173a50bf0	cmd/derper: add a rate limiter for accepting new connection (#3908 ) A large influx of new connections can bring down DERP since it spins off a new goroutine for each connection, where each routine may do significant amount of work (e.g., allocating memory and crunching numbers for TLS crypto). The momentary spike can cause the process to OOM. This commit sets the groundwork for limiting connections, but leaves the limit at infinite by default.

Aaron Klotz	3a74f2d2d7	cmd/tailscaled, util/winutil: add accessor functions for Windows system policies. This patch adds new functions to be used when accessing system policies, and revises callers to use the new functions. They first attempt the new registry path for policies, and if that fails, attempt to fall back to the legacy path. We keep non-policy variants of these functions because we should be able to retain the ability to read settings from locations that are not exposed to sysadmins for group policy edits. The remaining changes will be done in corp. Updates https://github.com/tailscale/tailscale/issues/3584 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	3 years ago

Brad Fitzpatrick	1af26222b6	go.mod: bump netstack, switch to upstream netstack Now that Go 1.17 has module graph pruning (https://go.dev/doc/go1.17#go-command), we should be able to use upstream netstack without breaking our private repo's build that then depends on the tailscale.com Go module. This is that experiment.

Brad Fitzpatrick	e6626366a2	cmd/tailscale: let 'tailscale up --reset' do a pref edit The --reset shouldn't imply that a Backend.Start is necessary. With this, it can do a Backend.EditPrefs instead, which then doesn't do all the heavy work that Start does. Also, Start on Windows behaves slightly differently than Linux etc in some cases because of tailscaled running in client mode on Windows (where the GUI supplies the prefs).
