Josh Bleecher Snyder	0868329936	all: use any instead of interface{} ... My favorite part of generics. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
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
Josh Bleecher Snyder	1b57b0380d	wgengine/magicsock: remove final alloc from ReceiveFrom ... And now that we don't have to play escape analysis and inlining games, simplify the code. 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. Updates #4146 (but not enough to fix it, something's still wrong) Updates #3802 Change-Id: I496d8cd7e31d45fe9ede88fc8894f35dc096de67 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
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 ...

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/.

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.

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.

This is for use by the Windows GUI client to log via when an exit node is in use, so the logs don't go out via the exit node and instead go directly, like tailscaled's. The dialer tried to do that in the unprivileged GUI by binding to a specific interface, but the "Internet Kill Switch" installed by tailscaled for exit nodes precludes that from working and instead the GUI fails to dial out. So, go through tailscaled (with a CONNECT request) instead.

Examples that weren't logged to disk: * logtail unable to dial out, * DNS flush messages from the service * svc.ChangeRequest messages (#3581) This is basically the same fix as #3571 but staying in the Logf type, and avoiding build-tagged file (which wasn't quite a goal, but happened and seemed nice) Fixes #3570 Co-authored-by: Aaron Klotz <aaron@tailscale.com> Change-Id: Iacd80c4720b7218365ec80ae143339d030842702	3 years ago

Brad Fitzpatrick	adc97e9c4d	cmd/tailscale: make --accept-routes default true on Windows, macOS GUI ... One of the most annoying parts of using the Tailscale CLI on Windows and the macOS GUI is that Tailscale's GUIs default to running with "Route All" (accept all non-exitnode subnet routes) but the CLI--being originally for Linux--uses the Linux default, which is to not accept subnets. Which means if a Windows user does, e.g.: tailscale up --advertise-exit-node Or: tailscale up --shields-up ... then it'd warn about reverting the --accept-routes option, which the user never explicitly used. Instead, make the CLI's default match the platform/GUI's default. Change-Id: I15c804b3d9b0266e9ca8651e0c09da0f96c9ef8d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
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
Brad Fitzpatrick	39ffa16853	net/dnscache, net/tsdial: add DNS caching to tsdial UserDial ... This is enough to handle the DNS queries as generated by Go's net package (which our HTTP/SOCKS client uses), and the responses generated by the ExitDNS DoH server. This isn't yet suitable for putting on 100.100.100.100 where a number of different DNS clients would hit it, as this doesn't yet do EDNS0. It might work, but it's untested and likely incomplete. Likewise, this doesn't handle anything about truncation, as the exchanges are entirely in memory between Go or DoH. That would also need to be handled later, if/when it's hooked up to 100.100.100.100.

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.
