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	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	6b71568eb7	util/cloudenv: add Azure support & DNS IPs And rewrite cloud detection to try to do only zero or one metadata discovery request for all clouds, only doing a first (or second) as confidence increases.

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.

James Tucker	8d6793fd70	wgengine/router,util/kmod: load & log xt_mark Attempt to load the xt_mark kernel module when it is not present. If the load fails, log error information. It may be tempting to promote this failure to an error once it has been in use for some time, so as to avoid reaching an error with the iptables invocation, however, there are conditions under which the two stages may disagree - this change adds more useful breadcrumbs. Example new output from tailscaled running under my WSL2: ``` router: ensure module xt_mark: "/usr/sbin/modprobe xt_mark" failed: exit status 1; modprobe: FATAL: Module xt_mark not found in directory /lib/modules/5.10.43.3-microsoft-standard-WSL2 ``` Background: There are two places to lookup modules, one is `/proc/modules` "old", the other is `/sys/module/` "new". There was query_modules(2) in linux <2.6, alas, it is gone. In a docker container in the default configuration, you would get /proc/modules and /sys/module/ both populated. lsmod may work file, modprobe will fail with EPERM at `finit_module()` for an unpriviliged container. In a priviliged container the load may succeed, if some conditions are met. This condition should be avoided, but the code landing in this change does not attempt to avoid this scenario as it is both difficult to detect, and has a very uncertain impact. In an nspawn container `/proc/modules` is populated, but `/sys/module` does not exist. Modern `lsmod` versions will fail to gather most module information, without sysfs being populated with module information. In WSL2 modules are likely missing, as the in-use kernel typically is not provided by the distribution filesystem, and WSL does not mount in a module filesystem of its own. Notably the WSL2 kernel supports iptables marks without listing the xt_mark module in /sys/module, and /proc/modules is empty. On a recent kernel, we can ask the capabilities system about SYS_MODULE, that will help to disambiguate between the non-privileged container case and just being root. On older kernels these calls may fail. Update #4329 Signed-off-by: James Tucker <james@tailscale.com>	3 years ago

Xe Iaso	4f1d6c53cb	cmd/nginx-auth: create new Tailscale NGINX auth service (#4400 ) This conforms to the NGINX subrequest result authentication protocol[1] using the NGINX module `ngx_http_auth_request_module`. This is based on the example that @peterkeen provided on Twitter[2], but with several changes to make things more tightly locked down: * This listens over a UNIX socket instead of a TCP socket to prevent leakage to the network * This uses systemd socket activation so that systemd owns the socket and can then lock down the service to the bare minimum required to do its job without having to worry about dropping permissions * This provides additional information in HTTP response headers that can be useful for integrating with various services * This has a script to automagically create debian and redhat packages for easier distribution This will be written about on the Tailscale blog. There is more information in README.md.

James Tucker	2550acfd9d	go.mod: bump netstack for clone reset fix (#4379 ) In tracking down issue #4144 and reading through the netstack code in detail, I discovered that the packet buf Clone path did not reset the packetbuf it was getting from the sync.Pool. The fix was sent upstream https://github.com/google/gvisor/pull/7385, and this bump pulls that in. At this time there is no known path that this fixes, however at the time of upstream submission this reset at least one field that could lead to incorrect packet routing if exercised, a situation that could therefore lead to an information leak.

Brad Fitzpatrick	39ffa16853	net/dnscache, net/tsdial: add DNS caching to tsdial UserDial This is enough to handle the DNS queries as generated by Go's net package (which our HTTP/SOCKS client uses), and the responses generated by the ExitDNS DoH server. This isn't yet suitable for putting on 100.100.100.100 where a number of different DNS clients would hit it, as this doesn't yet do EDNS0. It might work, but it's untested and likely incomplete. Likewise, this doesn't handle anything about truncation, as the exchanges are entirely in memory between Go or DoH. That would also need to be handled later, if/when it's hooked up to 100.100.100.100.
