c1ef55249a types/ipproto: import and test string parsing for ipproto
IPProto has been being converted to and from string formats in multiple
locations with variations in behavior. TextMarshaller and JSONMarshaller
implementations are now added, along with defined accepted and preferred
formats to centralize the logic into a single cross compatible
implementation.

9d96e05267 net/packet: split off checksum munging into different pkg
The current structure meant that we were embedding netstack in
the tailscale CLI and in the GUIs. This removes that by isolating
the checksum munging to a different pkg which is only called from
`net/tstun`.

fbfee6a8c0 cmd/containerboot: use linuxfw.NetfilterRunner
This migrates containerboot to reuse the NetfilterRunner used
by tailscaled instead of manipulating iptables rule itself.
This has the added advantage of now working with nftables and
we can potentially drop the `iptables` command from the container
image in the future.

net/dns/resolver: race UDP and TCP queries (#9544)
Instead of just falling back to making a TCP query to an upstream DNS
server when the UDP query returns a truncated query, also start a TCP
query in parallel with the UDP query after a given race timeout. This
ensures that if the upstream DNS server does not reply over UDP (or if
the response packet is blocked, or there's an error), we can still make
queries if the server replies to TCP queries.

This also adds a new package, util/race, to contain the logic required for
racing two different functions and returning the first non-error answer.

4823a7e591 cmd/containerboot: set TS_AUTH_ONCE default to true.
1.50.0 switched containerboot from using `tailscale up`
to `tailscale login`. A side-effect is that a re-usable
authkey is now re-applied on every boot by `tailscale login`,
where `tailscale up` would ignore an authkey if already
authenticated.

Though this looks like it is changing the default, in reality
it is setting the default to match what 1.48 and all
prior releases actually implemented.

4669e7f7d5 cmd/containerboot: add iptables based MSS clamping for ingress/egress proxies

results in packets being dropped when they make it to proxy pods as the tailscale0 interface
has a 1280 MTU.

As the primary use of this functionality is TCP, add iptables based MSS clamping to allow
connectivity.

19a9d9037f tailcfg: add NodeCapMap
Like PeerCapMap, add a field to `tailcfg.Node` which provides
a map of Capability to raw JSON messages which are deferred to be
parsed later by the application code which cares about the specific
capabilities. This effectively allows us to prototype new behavior
without having to commit to a schema in tailcfg, and it also opens up
the possibilities to develop custom behavior in tsnet applications w/o
having to plumb through application specific data in the MapResponse.

7c1ed38ab3 ipn/ipnlocal: fix missing controlknobs.Knobs plumbing
I missed connecting some controlknobs.Knobs pieces in 4e91cf20a8
resulting in that breaking control knobs entirely.

Whoops.

The fix in ipn/ipnlocal (where it makes a new controlclient) but to
atone, I also added integration tests. Those integration tests use
a new "tailscale debug control-knobs" which by itself might be useful
for future debugging.

4e91cf20a8 control/controlknobs, all: add plumbed Knobs type, not global variables
Previously two tsnet nodes in the same process couldn't have disjoint
sets of controlknob settings from control as both would overwrite each
other's global variables.

This plumbs a new controlknobs.Knobs type around everywhere and hangs
the knobs sent by control on that instead.

If the user's running "go test" by hand, no need to spam stderr with

on actual failure, or verbose mode) which is enough to tell users it's

        time.Sleep(3 * time.Second)
        os.Exit(1)
        t.Fatal("boom")
    }

Those three seconds let the other parallel tests (with all their
tailscaled child processes) start up and start running their tests,
but then we violently os.Exit(1) the test driver and all the children
were kept alive (and were spinning away, using all available CPU in
gvisor scheduler code, which is a separate scary issue)

While investigating the fix in 7538f38671,
I was curious why the testwrapper didn't fail. Turns out if the test
times out and there was no explicit failure, the only message we get
is that the overall pkg failed and no failure information about the
individual test. This resulted in a 0 exit code.

This fixes that by failing the explicit case of the pkg failing when
there is nothing to retry for that pkg.

d74c771fda client/web: always use new web client; remove old client
This uses the new react-based web client for all builds, not just with
the --dev flag.

If the web client assets have not been built, the client will serve a
message that Tailscale was built without the web client, and link to
build instructions. Because we will include the web client in all of our
builds, this should only be seen by developers or users building from
source. (And eventually this will be replaced by attempting to download
needed assets as runtime.)

We do now checkin the build/index.html file, which serves the error
message when assets are unavailable.  This will also eventually be used
to trigger in CI when new assets should be built and uploaded to a
well-known location.

c8dea67cbf cmd/k8s-operator: add support for Ingress resources
Previously, the operator would only monitor Services and create
a Tailscale StatefulSet which acted as a L3 proxy which proxied
traffic inbound to the Tailscale IP onto the services ClusterIP.

This extends that functionality to also monitor Ingress resources
where the `ingressClassName=tailscale` and similarly creates a
Tailscale StatefulSet, acting as a L7 proxy instead.

Users can override the desired hostname by setting:

```
- tls
  hosts:
  - "foo"
```

Hostnames specified under `rules` are ignored as we only create a single
host. This is emitted as an event for users to see.

320f77bd24 cmd/containerboot: add support for setting ServeConfig
This watches the provided path for a JSON encoded ipn.ServeConfig.
Everytime the file changes, or the nodes FQDN changes it reapplies
the ServeConfig.

At boot time, it nils out any previous ServeConfig just like tsnet does.

As the ServeConfig requires pre-existing knowledge of the nodes FQDN to do
SNI matching, it introduces a special `${TS_CERT_DOMAIN}` value in the JSON
file which is replaced with the known CertDomain before it is applied.

1. Add TCP port forwarding.
   For example: ./sniproxy -forwards=tcp/22/github.com
   will forward SSH to github.

   % ssh -i ~/.ssh/id_ecdsa.pem -T git@github.com
   Hi GitHubUser! You've successfully authenticated, but GitHub does not
   provide shell access.

   % ssh -i ~/.ssh/id_ecdsa.pem -T git@100.65.x.y
   Hi GitHubUser! You've successfully authenticated, but GitHub does not
   provide shell access.

2. Additionally export clientmetrics as prometheus metrics for local
   scraping over the tailnet: http://sniproxy-hostname:8080/debug/varz

5fb1695bcb util/osdiag, util/osdiag/internal/wsc: add code to probe the Windows Security Center for installed software
The Windows Security Center is a component that manages the registration of
security products on a Windows system. Only products that have obtained a
special cert from Microsoft may register themselves using the WSC API.
Practically speaking, most vendors do in fact sign up for the program as it
enhances their legitimacy.

From our perspective, this is useful because it gives us a high-signal
source of information to query for the security products installed on the
system. I've tied this query into the osdiag package and is run during
bugreports.

It uses COM bindings that were automatically generated by my prototype
metadata processor, however that program still has a few bugs, so I had
to make a few manual tweaks. I dropped those binding into an internal
package because (for the moment, at least) they are effectively
purpose-built for the osdiag use case.

We also update the wingoes dependency to pick up BSTR.

4511e7d64e ipn/ipnstate: add PeerStatus.AltSharerUserID, stop mangling Node.User
In b987b2ab18 (2021-01-12) when we introduced sharing we mapped
the sharer to the userid at a low layer, mostly to fix the display of
"tailscale status" and the client UIs, but also some tests.

The commit earlier today, 7dec09d169, removed the 2.5yo option
to let clients disable that automatic mapping, as clearly we were never
getting around to it.

This plumbs the Sharer UserID all the way to ipnstatus so the CLI
itself can choose to print out the Sharer's identity over the node's
original owner.

Then we stop mangling Node.User and let clients decide how they want
to render things.

To ease the migration for the Windows GUI (which currently operates on
tailcfg.Node via the NetMap from WatchIPNBus, instead of PeerStatus),
a new method Node.SharerOrUser is added to do the mapping of
Sharer-else-User.
