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	58f35261d0	cmd/tsconnect: remove debugging code Remove test prefix added to validate the error code from `27f36f77c3`. 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
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. It means CI won't fail if someone does something manually in the admin console. Signed-off-by: Xe <xe@tailscale.com>	2 years ago
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

Brad Fitzpatrick	c66f99fcdc	tailcfg, control/controlclient, ipn/ipnlocal: add c2n (control-to-node) system This lets the control plane can make HTTP requests to nodes. Then we can use this for future things rather than slapping more stuff into MapResponse, etc. Change-Id: Ic802078c50d33653ae1f79d1e5257e7ade4408fd Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Mihai Parparita	7d1357162e	cmd/tsconnect: expose runSSHSession in npm package Move it to lib/ so that it can be used in both the app and the package. 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).

Maisem Ali	9197dd14cc	net/dns: [win] add MagicDNS entries to etc/hosts This works around the 2.3s delay in short name lookups when SNR is enabled. C:\Windows\System32\drivers\etc\hosts file. We only add known hosts that match the search domains, and we populate the list in order of Search Domains so that our matching algorithm mimics what Windows would otherwise do itself if SNR was off.

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.

Tom DNetto	4001d0bf25	assorted: plumb tka initialization & network-lock key into tailscaled - A network-lock key is generated if it doesn't already exist, and stored in the StateStore.

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).

Mihai Parparita	52d769d35c	cmd/tsconnect: prefetch main.wasm when serving Avoids waterfalling of requests from the file (its load is triggered from JavaScript).

Mihai Parparita	f04bc31820	cmd/tsconnect: add -fast-compression option Changes Gzip and Brotli to optimize for speed instead of size.

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
