Brad Fitzpatrick	3ae701f0eb	net/tsaddr, wgengine/netstack: add IPv6 range that forwards to site-relative IPv4 This defines a new magic IPv6 prefix, fd7a:115c:a1e0:b1a::/64, a subset of our existing /48, where the final 32 bits are an IPv4 address, and the middle 32 bits are a user-chosen "site ID". (which must currently be 0000:00xx; the top 3 bytes must be zero for now) e.g., I can say my home LAN's "site ID" is "0000:00bb" and then advertise its 10.2.0.0/16 IPv4 range via IPv6, like: tailscale up --advertise-routes=fd7a:115c:a1e0:b1a::bb:10.2.0.0/112 (112 being /128 minuse the /96 v6 prefix length) Then people in my tailnet can: $ curl '[fd7a:115c:a1e0:b1a::bb:10.2.0.230]' <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ....

Brad Fitzpatrick	5df12b9059	client/tailscale, cmd/tailscale, localapi: add 'tailscale nc' (actually) Adds missing file from `fc12cbfcd3`. GitHub was having issues earlier and it was all green because the checks never actually ran, but the DCO non-Actions check at least did, so "green" and I merged, not realizing it hadn't really run anything.

Brad Fitzpatrick	fc12cbfcd3	client/tailscale, cmd/tailscale, localapi: add 'tailscale nc' This adds a "tailscale nc" command that acts a bit like "nc", but dials out via tailscaled via localapi. This is a step towards a "tailscale ssh", as we'll use "tailscale nc" as a ProxyCommand for in some cases (notably in userspace mode). But this is also just useful for debugging & scripting.

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.

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>	2 years ago

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).

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.

Got error: Get "http://local-tailscaled.sock/localapi/v0/status": EOF This was useful just now, as it made it clear that tailscaled I thought I was connecting to might not in fact be running; there was a second tailscaled running that made the error message slightly misleading.
