Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support ... As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114. Fixes #5617 Fixes tailscale/corp#1475 Change-Id: I72404e1789f9e56ec47f9b7021b44c025f7a373a Signed-off-by: Brad Fitzpatrick <bradfitz@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	11fcc3a7b0	cmd/tsconnect: fix xterm.js link opening not working when rendered into another window ... The default WebLinksAddon handler uses window.open(), but that gets blocked by the popup blocker when the event being handled is another window. We instead need to invoke open() on the window that the event was triggered in. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Will Norris	f03a63910d	cmd/tailscale: add licenses link to web UI ... The `tailscale web` UI is the primary interface for Synology and Home Assistant users (and perhaps others), so is the logical place to put our open source license notices. I don't love adding things to what is currently a very minimal UI, but I'm not sure of a better option. Updates tailscale/corp#5780 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago

Mihai Parparita	62035d6485	cmd/tsconnect: switch back to public version of xterm npm package ... xtermjs/xterm.js#4069 was merged and published (in 5.0.0-beta.58), no need for the fork added by 01e6565e8a. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago

Brad Fitzpatrick	58abae1f83	net/dns/{publicdns,resolver}: add NextDNS DoH support ... NextDNS is unique in that users create accounts and then get user-specific DNS IPs & DoH URLs. For DoH, the customer ID is in the URL path. For IPv6, the IP address includes the customer ID in the lower bits. For IPv4, there's a fragile "IP linking" mechanism to associate your public IPv4 with an assigned NextDNS IPv4 and that tuple maps to your customer ID. We don't use the IP linking mechanism. Instead, NextDNS is DoH-only. Which means using NextDNS necessarily shunts all DNS traffic through 100.100.100.100 (programming the OS to use 100.100.100.100 as the global resolver) because operating systems can't usually do DoH themselves. Once it's in Tailscale's DoH client, we then connect out to the known NextDNS IPv4/IPv6 anycast addresses. If the control plane sends the client a NextDNS IPv6 address, we then map it to the corresponding NextDNS DoH with the same client ID, and we dial that DoH server using the combination of v4/v6 anycast IPs.

Mihai Parparita	01e6565e8a	cmd/tsconnect: temporarily switch to xterm.js fork that handles popup windows ... Allows other work to be unblocked while xtermjs/xterm.js#4069 is worked through.

Mihai Parparita	2f702b150e	cmd/tsconnect: add dev-pkg command for two-sided development ... Allows imports of the NPM package added by 1a093ef482 to be replaced with import("http://localhost:9090/pkg/pkg.js"), so that changes can be made in parallel to both the module and code that uses it (without any need for NPM publishing or even building of the package).

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.

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.
