nyghtowl	cfbbcf6d07	cmd/nginx-auth/nginx-auth: update auth to allow for new domains ... With MagicDNS GA, we are giving every tailnet a tailnet-<hex>.ts.net name. We will only parse out if legacy domains include beta.tailscale.net; otherwise, set tailnet to the full domain format going forward. Signed-off-by: nyghtowl <warrick@tailscale.com>	2 years ago
Andrew Dunham	c72caa6672	wgengine/magicsock: use AF_PACKET socket + BPF to read disco messages ... This is entirely optional (i.e. failing in this code is non-fatal) and only enabled on Linux for now. Additionally, this new behaviour can be disabled by setting the TS_DEBUG_DISABLE_AF_PACKET environment variable.

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
Xe Iaso	122bd667dc	cmd/gitops-pusher: be less paranoid about external modifications (#5488) ... This makes a "modified externally" error turn into a "modified externally" warning.

Mihai Parparita	2c18517121	cmd/tsconnect: add npm publish workflow ... Adds an on-demand GitHub Action that publishes the package to the npm registry (currently under tailscale-connect, will be moved to @tailscale/connect once we get control of the npm org). Makes the package.json for the NPM package be dynamically generated to have the current Tailscale client version. Updates #5415 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. Updates #5415 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Will Norris	b3cc719add	cmd/nginx-auth: allow use of shared nodes ... When sharing nodes, the name of the sharee node is not exposed (instead it is hardcoded to "device-of-shared-to-user"), which means that we can't determine the tailnet of that node. Don't immediately fail when that happens, since it only matters if "Expected-Tailnet" is used. Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Mihai Parparita	78b90c3685	cmd/tsconnect: stop writing build artifacts into src/ ... We can't write to src/ when tsconnect is used a dependency in another repo (see also b763a12331). We therefore need to switch from writing to src/ to using esbuild plugins to handle the requests for wasm_exec.js (the Go JS runtime for Wasm) and the Wasm build of the Go module. This has the benefit of allowing Go/Wasm changes to be picked up without restarting the server when in dev mode (Go compilation is fast enough that we can do this on every request, CSS compilation continues to be the long pole).

Joe Tsai	1f7479466e	util/deephash: use sha256x (#5339) ... Switch deephash to use sha256x.Hash. We add sha256x.HashString to efficiently hash a string. It uses unsafe under the hood to convert a string to a []byte. We also modify sha256x.Hash to export the underlying hash.Hash for testing purposes so that we can intercept all hash.Hash calls. Performance: name old time/op new time/op delta Hash-24 19.8µs ± 1% 19.2µs ± 1% -3.01% (p=0.000 n=10+10) HashPacketFilter-24 2.61µs ± 0% 2.53µs ± 1% -3.01% (p=0.000 n=8+10) HashMapAcyclic-24 31.3µs ± 1% 29.8µs ± 0% -4.80% (p=0.000 n=10+9) TailcfgNode-24 1.83µs ± 1% 1.82µs ± 2% ~ (p=0.305 n=10+10) HashArray-24 344ns ± 2% 323ns ± 1% -6.02% (p=0.000 n=9+10) The performance gains is not as dramatic as sha256x over sha256 due to: 1. most of the hashing already occurring through the direct memory hashing logic, and 2. what does not go through direct memory hashing is slowed down by reflect.

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.

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	617a2ec7cc	cmd/tsconnect: add Tailwind CSS support and switch to using it ... Integrates Tailwind CSS as an esbuild plugin that invokes the CLI to process the input. It takes ~400ms, so it seems like the easiest option (vs running a separate process for dev mode). Existing minimal look and feel is replicated with Tailwind classes, mostly to prove that the entire system works, including unused class removal.

Xe Iaso	898695e312	cmd/gitops-pusher: add etag cache file for the three version problem (#5124) ... This allows gitops-pusher to detect external ACL changes. I'm not sure what to call this problem, so I've been calling it the "three version problem" in my notes. The basic problem is that at any given time we only have two versions of the ACL file at any given point: the version in CONTROL and the one in the git repo. In order to check if there has been tampering of the ACL files in the admin panel, we need to have a _third_ version to compare against. In this case I am not storing the old ACL entirely (though that could be a reasonable thing to add in the future), but only its sha256sum. This allows us to detect if the shasum in control matches the shasum we expect, and if that expectation fails, then we can react accordingly. This will require additional configuration in CI, but I'm sure that can be done. Signed-off-by: Xe <xe@tailscale.com>	2 years ago

Mihai Parparita	b763a12331	cmd/tsconnect: allow building static resources in a different directory ... When using tsconnect as a module in another repo, we cannot write to the ./dist directory (modules directories are read-only by default - there is a -modcacherw flag for `go get` but we can't count on it). We add a -distdir flag that is honored by both the build and serve commands for where to place output in. Somewhat tedious because esbuild outputs paths relative to the working directory, so we need to do some extra munging to make them relative to the output directory.

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

Brad Fitzpatrick	88c2afd1e3	ipn/ipnlocal, net/dns*, util/cloudenv: specialize DNS config on Google Cloud ... This does three things: * If you're on GCP, it adds a *.internal DNS split route to the metadata server, so we never break GCP DNS names. This lets people have some Tailscale nodes on GCP and some not (e.g. laptops at home) without having to add a Tailnet-wide *.internal DNS route. If you already have such a route, though, it won't overwrite it. * If the 100.100.100.100 DNS forwarder has nowhere to forward to, it forwards it to the GCP metadata IP, which forwards to 8.8.8.8. This means there are never errNoUpstreams ("upstream nameservers not set") errors on GCP due to e.g. mangled /etc/resolv.conf (GCP default VMs don't have systemd-resolved, so it's likely a DNS supremacy fight) * makes the DNS fallback mechanism use the GCP metadata IP as a fallback before our hosted HTTP-based fallbacks I created a default GCP VM from their web wizard. It has no systemd-resolved. I then made its /etc/resolv.conf be empty and deleted its GCP hostnames in /etc/hosts. I then logged in to a tailnet with no global DNS settings. With this, tailscaled writes /etc/resolv.conf (direct mode, as no systemd-resolved) and sets it to 100.100.100.100, which then has regular DNS via the metadata IP and *.internal DNS via the metadata IP as well. If the tailnet configures explicit DNS servers, those are used instead, except for *.internal. This also adds a new util/cloudenv package based on version/distro where the cloud type is only detected once. We'll likely expand it in the future for other clouds, doing variants of this change for other popular cloud environments.
