davideger	f31546809f	cmd/tailscale: propagate tailscaled 403s as AccessDeniedErrors So Linux/etc CLI users get helpful advice to run tailscale with --operator=$USER when they try to 'tailscale file {cp,get}' but are mysteriously forbidden.

Brad Fitzpatrick	f3c0023add	wgengine/netstack: add an SSH server experiment Disabled by default. To use, run tailscaled with: TS_SSH_ALLOW_LOGIN=you@bar.com And enable with: $ TAILSCALE_USE_WIP_CODE=true tailscale up --ssh=true Then ssh [any-user]@[your-tailscale-ip] for a root bash shell.

Josh Bleecher Snyder	a076aaecc6	cmd/tailscale: use html/template for synoTokenRedirect The GitHub code scanner flagged this as a security vulnerability. I don't believe it was, but I couldn't convince myself of it 100%. Err on the safe side and use html/template to generate the HTML, with all necessary escaping.

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	7d9b1de3aa	netcheck,portmapper,magicsock: ignore some UDP write errors on Linux Treat UDP send EPERM errors as a lost UDP packet, not something super fatal. That's just the Linux firewall preventing it from going out. And add a leaf package net/neterror for that (and future) policy that all three packages can share, with tests.

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.

Josh Bleecher Snyder	de635ac0a8	cmd/tailscale: print more detail in connection failure error message Before: failed to connect to local tailscaled (which appears to be running). Got error: Get "http://local-tailscaled.sock/localapi/v0/status": EOF After: failed to connect to local tailscaled (which appears to be running as IPNExtension, pid 2118). 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.

Aaron Klotz	7d8feb2784	hostinfo: change Windows implementation to directly query version information using API and registry We replace the cmd.exe invocation with RtlGetNtVersionNumbers for the first three fields. On Windows 10+, we query for the fourth field which is available via the registry. The fourth field is not really documented anywhere; Firefox has been querying it successfully since Windows 10 was released, so we can be pretty confident in its longevity at this point.
