Mihai Parparita	8343b243e7	all: consistently initialize Logf when creating tsdial.Dialers Most visible when using tsnet.Server, but could have resulted in dropped messages in a few other places too. Fixes #5743 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	8158dd2edc	cmd/tsconnect: allow SSH connection timeout to be overridden 5 seconds may not be enough if we're still loading the derp map and connecting to a slow machine. Updates #5693 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	c312e0d264	cmd/tsconnect: allow hostname to be specified The auto-generated hostname is nice as a default, but there are cases where the client has a more specific name that it can generate. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	2400ba28b1	cmd/tsconnect: handle terminal resizes before the SSH session is created Store the requested size is a struct field, and use that when actually creating the SSH session. Fixes #5567 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	27f36f77c3	cmd/tsconnect: output errors to the JS console too We were just outputting them to the terminal, but that's hard to debug because we immediately tear down the terminal when getting an error. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	1a093ef482	cmd/tsconnect: extract NPM package for reusing in other projects `src/` is broken up into several subdirectories: - `lib/` and `types`/ for shared code and type definitions (more code will be moved here) - `app/` for the existing Preact-app - `pkg/` for the new NPM package A new `build-pkg` esbuild-based command is added to generate the files for the NPM package. To generate type definitions (something that esbuild does not do), we set up `dts-bundle-generator`. Includes additional cleanups to the Wasm type definitions (we switch to string literals for enums, since exported const enums are hard to use via packages). Also allows the control URL to be set a runtime (in addition to the current build option), so that we don't have to rebuild the package for dev vs. prod use.

Charlotte Brandhorst-Satzkorn	0f12ead567	tsconnect: pass in authkey in dev mode (#5320 ) This change allows for an auth key to be specified as a url query param for use in development mode. If an auth key is specified and valid, it will authorize the client for use immediately. Updates #5144 Signed-off-by: Charlotte Brandhorst-Satzkorn <charlotte@tailscale.com>	2 years ago
Mihai Parparita	ab159f748b	cmd/tsconnect: switch UI to Preact Reduces the amount of boilerplate to render the UI and makes it easier to respond to state changes (e.g. machine getting authorized, netmap changing, etc.) Preact adds ~13K to our bundle size (5K after Brotli) thus is a neglibible size contribution. We mitigate the delay in rendering the UI by having a static placeholder in the HTML. Required bumping the esbuild version to pick up evanw/esbuild#2349, which makes it easier to support Preact's JSX code generation. Fixes #5137 Fixes #5273 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Charlotte Brandhorst-Satzkorn	5055e00cf1	tsconnect: add flag to specify control server (#5294 ) To improve the local development experience, this change allows a control url to be passed in with the `--dev-control=` flag. If the flag is passed in when not specifying dev, an error is returned. If no flag is passed, the default remains the Tailscale controlled control server set by `ipn.DefaultControlURL`.

Mihai Parparita	f371a1afd9	cmd/tsconnect: make logtail uploading work Initialize logtail and provide an uploader that works in the browser (we make a no-cors cross-origin request to avoid having to open up the logcatcher servers to CORS). Fixes #5147 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	adc5ffea99	cmd/tsconnect: make PeerAPI work JS -> native nodes worked already, tested by exposing a fetch() method to JS (it's Promise-based to be consistent with the native fetch() API). Native nodes -> JS almost worked, we just needed to set the LocalBackend on the userspace netstack. Fixes #5130 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	9a2171e4ea	cmd/tsconnect: make terminal resizable Makes the terminal container DOM node as large as the window (except for the header) via flexbox. The xterm.js terminal is then sized to fit via xterm-addon-fit. Once we have a computed rows/columns size, and we can tell the SSH session of the computed size. Required introducing an IPNSSHSession type to allow the JS to control the SSH session once opened. That alse allows us to programatically close it, which we do when the user closes the window with the session still active. I initially wanted to open the terminal in a new window instead (so that it could be resizable independently of the main window), but xterm.js does not appear to work well in that mode (possibly because it adds an IntersectionObserver to pause rendering when the window is not visible, and it ends up doing that when the parent window is hidden -- see xtermjs/xterm.js@87dca56dee) Fixes #5150 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	c06758c83b	cmd/tsconnect: allow SSH username to be specified Redoes the UI to be a form, with a username field and a host drop-down. Fixes #5139 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	a3d74c4548	cmd/tsconnect: add basic panic handling The go wasm process exiting is a sign of an unhandled panic. Also add a explicit recover() call in the notify callback, that's where most logic bugs are likely to happen (and they may not be fatal). Also fixes the one panic that was encountered (nill pointer dereference when generating the JS view of the netmap). Fixes #5132 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	389629258b	cmd/tsconnect: switch to TypeScript Continues to use esbuild for development mode and building. Also includes a `yarn lint` script that uses tsc to do full type checking. Fixes #5138 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Brad Fitzpatrick	a12aad6b47	all: convert more code to use net/netip directly perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.) perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. ) goimports -w . Then delete some stuff from the net/netaddr shim package which is no longer neeed.

Mihai Parparita	6f5096fa61	cmd/tsconnect: initial scaffolding for Tailscale Connect browser client Runs a Tailscale client in the browser (via a WebAssembly build of the wasm package) and allows SSH access to machines. The wasm package exports a newIPN function, which returns a simple JS object with methods like start(), login(), logout() and ssh(). The golang.org/x/crypto/ssh package is used for the SSH client. Terminal emulation and QR code renedring is done via NPM packages (xterm and qrcode respectively), thus we also need a JS toolchain that can install and bundle them. Yarn is used for installation, and esbuild handles loading them and bundling for production serving. Updates #3157 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
