Mihai Parparita	a9f32656f5	control/controlhttp: allow client and server to communicate over WebSockets ... We can't do Noise-over-HTTP in Wasm/JS (because we don't have bidirectional communication), but we should be able to do it over WebSockets. Reuses derp WebSocket support that allows us to turn a WebSocket connection into a net.Conn. Updates #3157 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Maisem Ali	67325d334e	cmd/tailscale/cli: add lose-ssh risk ... This makes it so that the user is notified that the action they are about to take may result in them getting disconnected from the machine. It then waits for 5s for the user to maybe Ctrl+C out of it. It also introduces a `--accept-risk=lose-ssh` flag for automation, which allows the caller to pre-acknowledge the risk. The two actions that cause this are: - updating `--ssh` from `true` to `false` - running `tailscale down` Updates #3802 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Brad Fitzpatrick	4d85cf586b	cmd/tailscale, ipn/ipnlocal: add "peerapi" ping type ... For debugging when stuff like #4750 isn't working. RELNOTE=tailscale ping -peerapi Change-Id: I9c52c90fb046e3ab7d2b121387073319fbf27b99 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Aaron Klotz	b005b79236	net/dns, paths, util/winutil: change net/dns/windowsManager NRPT management to support more than 50 domains. ... AFAICT this isn't documented on MSDN, but based on the issue referenced below, NRPT rules are not working when a rule specifies > 50 domains. This patch modifies our NRPT rule generator to split the list of domains into chunks as necessary, and write a separate rule for each chunk. For compatibility reasons, we continue to use the hard-coded rule ID, but as additional rules are required, we generate new GUIDs. Those GUIDs are stored under the Tailscale registry path so that we know which rules are ours. I made some changes to winutils to add additional helper functions in support of both the code and its test: I added additional registry accessors, and also moved some token accessors from paths to util/winutil.

Aaron Klotz	c163b2a3f1	util/winutil, util/winutil/vss: remove winrestore and vss as they are unnecessary. ... I wrote this code way back at the beginning of my tenure at Tailscale when we had concerns about needing to restore deleted machine keys from backups. We never ended up using this functionality, and the code is now getting in the way, so we might as well remove it. Signed-off-by: Aaron Klotz <aaron@tailscale.com>	2 years ago
Mihai Parparita	eda647cb47	cmd/tailscale/cli: fix ssh CLI command breaking the Wasm build ... Adds a stub for syscall.Exec when GOOS=js.

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.

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.

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
