cmd/netlogfmt: handle any stream of network logs (#6108)
Make netlogfmt useful regardless of the exact schema of the input.
If a JSON object looks like a network log message,
then unmarshal it as one and then print it.
This allows netlogfmt to support both a stream of JSON objects
directly serialized from netlogtype.Message, or the schema
returned by the /api/v2/tailnet/{{tailnet}}/network-logs API endpoint.

types/netlogtype: new package for network logging types (#6092)
The netlog.Message type is useful to depend on from other packages,
but doing so would transitively cause gvisor and other large packages
to be linked in.

Avoid this problem by moving all network logging types to a single package.

We also update staticcheck to take in:

Brad Fitzpatrick e24de8a617 ssh/tailssh: add password-forcing workaround for buggy SSH clients
If the username includes a suffix of +password, then we accept
password auth and just let them in like it were no auth.

This exists purely for SSH clients that get confused by seeing success
to their initial auth type "none".

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.

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.

Fixes #4911

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.

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.

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

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.

Maxime VISONNEAU 4528f448d6 ipn/store/aws, cmd/tailscaled: add AWS SSM ipn.StateStore implementation
From https://github.com/tailscale/tailscale/pull/1919 with
edits by bradfitz@.

This change introduces a new storage provider for the state file. It
allows users to leverage AWS SSM parameter store natively within
tailscaled, like:

    $ tailscaled --state=arn:aws:ssm:eu-west-1:123456789:parameter/foo

Known limitations:
- it is not currently possible to specific a custom KMS key ID

RELNOTE=tailscaled on Linux supports using AWS SSM for state

Brad Fitzpatrick 7cf8ec8108 net/tlsdial: bake in LetsEncrypt's ISRG Root X1 root
We still try the host's x509 roots first, but if that fails (like if
the host is old), we fall back to using LetsEncrypt's root and
retrying with that.

tlsdial was used in the three main places: logs, control, DERP. But it
was missing in dnsfallback. So added it there too, so we can run fine
now on a machine with no DNS config and no root CAs configured.

Also, move SSLKEYLOGFILE support out of DERP. tlsdial is the logical place
for that support.

Fixes #1609

tstest/integration/vms: codegen for top level tests (#2441)
This moves the distribution definitions into a maintainable hujson file
instead of just existing as constants in `distros.go`. Comments are
maintained from the inline definitions.

This uses jennifer[1] for hygenic source tree creation. This allows us
to generate a unique top-level test for each VM run. This should
hopefully help make the output of `go test` easier to read.

This also separates each test out into its own top-level test so that we
can better track the time that each distro takes. I really wish there
was a way to have the `test_codegen.go` file _always_ run as a part of
the compile process instead of having to rely on people remembering to
run `go generate`, but I am limited by my tools.

This will let us remove the `-distro-regex` flag and use `go test -run`
to pick which distros are run.

tstest/integration/vms: download images from s3 (#2035)
This makes integration tests pull pristine VM images from Amazon S3 if
they don't exist on disk. If the S3 fetch fails, it will fall back to
grabbing the image from the public internet. The VM images on the public
internet are known to be updated without warning and thusly change their
SHA256 checksum. This is not ideal for a test that we want to be able to
fire and forget, then run reliably for a very long time.

This requires an AWS profile to be configured at the default path. The
S3 bucket is rigged so that the requester pays. The VM images are
currently about 6.9 gigabytes. Please keep this in mind when running
these tests on your machine.

Documentation was added to the integration test folder to aid others in
running these tests on their machine.

Some wording in the logs of the tests was altered.

Josh Bleecher Snyder b3ceca1dd7 wgengine/...: split into multiple receive functions
Upstream wireguard-go has changed its receive model.
NewDevice now accepts a conn.Bind interface.

The conn.Bind is stateless; magicsock.Conns are stateful.
To work around this, we add a connBind type that supports
cheap teardown and bring-up, backed by a Conn.

The new conn.Bind allows us to specify a set of receive functions,
rather than having to shoehorn everything into ReceiveIPv4 and ReceiveIPv6.
This lets us plumbing DERP messages directly into wireguard-go,
instead of having to mux them via ReceiveIPv4.

One consequence of the new conn.Bind layer is that
closing the wireguard-go device is now indistinguishable
from the routine bring-up and tear-down normally experienced
by a conn.Bind. We thus have to explicitly close the magicsock.Conn
when the close the wireguard-go device.

One downside of this change is that we are reliant on wireguard-go
to call receiveDERP to process DERP messages. This is fine for now,
but is perhaps something we should fix in the future.

control/controlclient: sign RegisterRequest (#1549)
control/controlclient: sign RegisterRequest

Some customers wish to verify eligibility for devices to join their
tailnets using machine identity certificates. TLS client certs could
potentially fulfill this role but the initial customer for this feature
has technical requirements that prevent their use. Instead, the
certificate is loaded from the Windows local machine certificate store
and uses its RSA public key to sign the RegisterRequest message.

There is room to improve the flexibility of this feature in future and
it is currently only tested on Windows (although Darwin theoretically
works too), but this offers a reasonable starting place for now.

David Anderson ce45f4f3ff wgengine/filter: inline ip6InList into match.
matchIPsOnly gets 5% slower when inlining, despite significantly reduced
memory ops and slightly tighter code.

Part of #19.

tsweb: refactor JSONHandler to take status code from error if it is present (#905)
This change is to make JSONHandler error handling intuitive, as before there would be two sources of HTTP status code when HTTPErrors were generated: one as the first return value of the handler function, and one nested inside the HTTPError. Previously, it took the first return value as the status code, and ignored the code inside the HTTPError. Now, it should expect the first return value to be 0 if there is an error, and it takes the status code of the HTTPError to set as the response code.
