James Tucker 1858ad65c8 cmd/cloner: do not allocate slices when the source is nil
tailcfg.Node zero-value clone equality checks failed when I added a

Marwan Sulaiman f3a5bfb1b9 cmd/tailscale/cli: add set serve validations
This PR adds validations for the new new funnel/serve
commands under the following rules:
1. There is always a single config for one port (bg or fg).
2. Foreground configs under the same port cannot co-exists (for now).
3. Background configs can change as long as the serve type is the same.

Brad Fitzpatrick 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.

Brad Fitzpatrick 055fdb235f cmd/tailscaled, tstest/integration: make tailscaled die when parent dies
I noticed that failed tests were leaving aroudn stray tailscaled processes
on macOS at least.

To repro, add this to tstest/integration:

    func TestFailInFewSeconds(t *testing.T) {
        t.Parallel()
        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)

individual test. This resulted in a 0 exit code.

Will Norris 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.

Maisem Ali c8dea67cbf cmd/k8s-operator: add support for Ingress resources

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"
```

host. This is emitted as an event for users to see.

Aaron Klotz 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.

Brad Fitzpatrick 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.

Previously, tailscale upgrade was doing the bare minimum for checking
authenticode signatures via `WinVerifyTrustEx`. This is fine, but we can do
better:

* WinVerifyTrustEx verifies that the binary's signature is valid, but it doesn't
  determine *whose* signature is valid; tailscale upgrade should also ensure that
  the binary is actually signed *by us*.
* I added the ability to check the signatures of MSI files.
* In future PRs I will be adding diagnostic logging that lists details about
  every module (ie, DLL) loaded into our process. As part of that metadata, I
  want to be able to extract information about who signed the binaries.

Charlotte Brandhorst-Satzkorn 35bdbeda9f cli: introduce exit-node subcommand to list and filter exit nodes
This change introduces a new subcommand, `exit-node`, along with a
subsubcommand of `list` and a `--filter` flag.

Exit nodes without location data will continue to be displayed when
`status` is used. Exit nodes with location data will only be displayed
behind `exit-node list`, and in status if they are the active exit node.

The `filter` flag can be used to filter exit nodes with location data by
country.

Exit nodes with Location.Priority data will have only the highest
priority option for each country and city listed. For countries with
multiple cities, a <Country> <Any> option will be displayed, indicating
the highest priority node within that country.

Define PeerCapabilty and PeerCapMap as the new way of sending down

Previously, this was unstructured and you could only send down strings

Brad Fitzpatrick 88cc0ad9f7 util/linuxfw: remove yet-unused code to fix linux/arm64 crash
The util/linuxfw/iptables.go had a bunch of code that wasn't yet used
(in prep for future work) but because of its imports, ended up
initializing code deep within gvisor that panicked on init on arm64
systems not using 4KB pages.

This deletes the unused code to delete the imports and remove the
panic. We can then cherry-pick this back to the branch and restore it
later in a different way.

A new test makes sure we don't regress in the future by depending on
the panicking package in question.

logtail: be less aggressive about re-uploads (#8117)
The retry logic was pathological in the following ways:

* If we restarted the logging service, any pending uploads
would be placed in a retry-loop where it depended on backoff.Backoff,
which was too aggresive. It would retry failures within milliseconds,
taking at least 10 retries to hit a delay of 1 second.

* In the event where a logstream was rate limited,
the aggressive retry logic would severely exacerbate the problem
since each retry would also log an error message.
It is by chance that the rate of log error spam
does not happen to exceed the rate limit itself.

We modify the retry logic in the following ways:

* We now respect the "Retry-After" header sent by the logging service.

* Lacking a "Retry-After" header, we retry after a hard-coded period of
30 to 60 seconds. This avoids the thundering-herd effect when all nodes
try reconnecting to the logging service at the same time after a restart.

* We do not treat a status 400 as having been uploaded.
This is simply not the behavior of the logging service.

If a endpoint has not been used before, an address is randomly selected
to be used based on information we know about, such as if they are able
to use IPv4 or IPv6. When an address is initially selected, we also
initiate a new ICMP ping to the endpoints addresses to determine which
endpoint offers the best latency. This information is then used to
update which endpoint we should be using based on the best possible
route. If the latency is the same for a IPv4 and an IPv6 address, IPv6
will be used.

Anton Tolchanov 8546ff98fb tsweb: move varz handler(s) into separate modules
This splits Prometheus metric handlers exposed by tsweb into two
modules:
- `varz.Handler` exposes Prometheus metrics generated by our expvar
  converter;
- `promvarz.Handler` combines our expvar-converted metrics and native
  Prometheus metrics.

By default, tsweb will use the promvarz handler, however users can keep
using only the expvar converter. Specifically, `tailscaled` now uses
`varz.Handler` explicitly, which avoids a dependency on the
(heavyweight) Prometheus client.

to, so devs don't have to edit the ACLs in the admin console to add a
custom DERP map.

3. Explaining how the -dev and -a command lines args to derper
interact.

To use this:

1. Run derper with -dev.

2. Run tailscaled with TS_DEBUG_USE_DERP_HTTP=1 and
TS_DEBUG_USE_DERP_ADDR=localhost

This will result in the client connecting to derp via HTTP on port
3340.

Aaron Klotz 90fd04cbde ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled
I realized that a lot of the problems that we're seeing around migration and
LocalBackend state can be avoided if we drive Windows pref migration entirely
from within tailscaled. By doing it this way, tailscaled can automatically
perform the migration as soon as the connection with the client frontend is
established.

Since tailscaled is already running as LocalSystem, it already has access to
the user's local AppData directory. The profile manager already knows which
user is connected, so we simply need to resolve the user's prefs file and read
it from there.

Of course, to properly migrate this information we need to also check system
policies. I moved a bunch of policy resolution code out of the GUI and into
a new package in util/winutil/policy.

Andrew Dunham 8d3acc9235 util/sysresources, magicsock: scale DERP buffer based on system memory
This adds the util/sysresources package, which currently only contains a
function to return the total memory size of the current system.

Then, we modify magicsock to scale the number of buffered DERP messages
based on the system's available memory, ensuring that we never use a
value lower than the previous constant of 32.

Allow the directory to be passed in via a -rootdir flag (the repo that
depends on it can then use `go list -m -f '{{.Dir}}' tailscale.com`

Maisem Ali be027a9899 control/controlclient: improve handling of concurrent lite map requests
This reverts commit 6eca47b16c and fixes forward.

Previously the first ever streaming MapRequest that a client sent would also
set ReadOnly to true as it didn't have any endpoints and expected/relied on the
map poll to restart as soon as it got endpoints. However with 48f6c1eba4,
we would no longer restart MapRequests as frequently as we used to, so control
would only ever get the first streaming MapRequest which had ReadOnly=true.

Control would treat this as an uninteresting request and would not send it
any further netmaps, while the client would happily stay in the map poll forever
while litemap updates happened in parallel.

This makes it so that we never set `ReadOnly=true` when we are doing a streaming
MapRequest. This is no longer necessary either as most endpoint discovery happens
over disco anyway.

Enabled on iOS, macOS and Android only, since mobile platforms are the
ones we're most interested in, and we are less sensitive to any
throughput degradation due to the per-I/O callback overhead (macOS is
also enabled for ease of testing during development).

For now just exposed as counters on a /v0/sockstats PeerAPI endpoint.
