Josh Bleecher Snyder	997b19545b	syncs: use TryLock and TryRLock instead of unsafe The docs say: Note that while correct uses of TryLock do exist, they are rare, and use of TryLock is often a sign of a deeper problem in a particular use of mutexes. Rare code! Or bad code! Who can tell! Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	ead16b24ec	cmd/tailscaled: fail early with nice error on macOS with go1.18 Due to golang/go#51759 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Denton Gentry	d8953bf2ba	cmd/derpprobe: don't alert for smaller failures. There is a Cosmic Background level of DERP Unreachability, with individual nodes or regions becoming unreachable briefly and returning a short time later. This is due to hosting provider outages or just the Internet sloshing about. Returning a 500 error pages a human. Being awoken at 3am for a transient error is annoying. For relatively small levels of badness don't page a human, just post to Slack. If the outage impacts a significant fraction of the DERP fleet, then page a human.

Josh Bleecher Snyder	8c2cb4b431	go.mod: update to latest certstore It includes a fix to allow us to use Go 1.18. We can now remove our Tailscale-only build tags. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	1f22507c06	version: use Go 1.18's git stamping as default implementation No more manual version bumps! Fixes #81 Change-Id: I3a9e544a7248f0b83bcbacbaabbc4dabc435e62d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	26021b07ec	control/controlclient: only build certstore-related code with the Tailscale Go toolchain The certstore code is impacted by golang/go#51726. The Tailscale Go toolchain fork contains a temporary workaround, so it can compile it. Once the upstream toolchain can compile certstore, presumably in Go 1.18.1, we can revert this change. Note that depaware runs with the upstream toolchain. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	ba1adf6c24	ssh/tailssh: make pty termios options match OpenSSH Still not sure the exact rules of how/when/who's supposed to set these, but this works for now on making them match. Baby steps. Will research more and adjust later.

Aaron Klotz	f8a4df66de	cmd/tailscale/cli, ipn: move exit node IP parsing and validation from cli into prefs. We need to be able to provide the ability for the GUI clients to resolve and set the exit node IP from an untrusted string, thus enabling the ability to specify that information via enterprise policy. This patch moves the relevant code out of the handler for `tailscale up`, into a method on `Prefs` that may then be called by GUI clients. We also update tests accordingly.

Joonas Kuorilehto	c1b3500a05	cmd/tailscale: allow use of flags in gokrazy Enable use of command line arguments with tailscale cli on gokrazy. Before this change using arguments like "up" would cause tailscale cli to be repeatedly restarted by gokrazy process supervisor. We never want to have gokrazy restart tailscale cli, even if user would manually start the process. Expected usage is that user creates files: flags/tailscale.com/cmd/tailscale/flags.txt: up flags/tailscale.com/cmd/tailscaled/flags.txt: --statedir=/perm/tailscaled/ --tun=userspace-networking Then tailscale prints URL for user to log in with browser. Alternatively it should be possible to use up with auth key to allow unattended gokrazy installs. Signed-off-by: Joonas Kuorilehto <joneskoo@derbian.fi>	3 years ago

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.

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	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.

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.
