James Tucker 24bac27632 util/rands: add Shuffle and Perm functions with on-stack RNG state
The new math/rand/v2 package includes an m-local global random number
generator that can not be reseeded by the user, which is suitable for
most uses without the RNG pools we have in a number of areas of the code
base.

The new API still does not have an allocation-free way of performing a
seeded operations, due to the long term compiler bug around interface
parameter escapes, and the Source interface.

This change introduces the two APIs that math/rand/v2 can not yet
replace efficiently: seeded Perm() and Shuffle() operations. This
implementation chooses to use the PCG random source from math/rand/v2,
as with sufficient compiler optimization, this source should boil down
to only two on-stack registers for random state under ideal conditions.

 - the management client in tailscaled is not started (though if it is

 - the client does not prompt the user to login or switch to the

cmd/{containerboot,k8s-operator/deploy/manifests}: optionally allow proxying cluster traffic to a cluster target via ingress proxy (#11036)
* cmd/containerboot,cmd/k8s-operator/deploy/manifests: optionally forward cluster traffic via ingress proxy.

If a tailscale Ingress has tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation, configure the associated ingress proxy to have its tailscale serve proxy to listen on Pod's IP address. This ensures that cluster traffic too can be forwarded via this proxy to the ingress backend(s).

In containerboot, if EXPERIMENTAL_PROXY_CLUSTER_TRAFFIC_VIA_INGRESS is set to true
and the node is Kubernetes operator ingress proxy configured via Ingress,
make sure that traffic from within the cluster can be proxied to the ingress target.

Will Norris 13f8a669d5 cmd/gitops-pusher: fix logic for checking credentials
gitops-pusher supports authenticating with an API key or OAuth
credentials (added in #7393). You shouldn't ever use both of those
together, so we error if both are set.

In tailscale/gitops-acl-action#24, OAuth support is being added to the
GitHub action. In that environment, both the TS_API_KEY and OAuth
variables will be set, even if they are empty values.  This causes an
error in gitops-pusher which expects only one to be set.

Update gitops-pusher to check that only one set of environment variables
are non-empty, rather than just checking if they are set.

cmd/k8s-operator: fix base truncating for extra long Service names (#10825)
cmd/k8s-operator: fix base truncating for extra long Service names

StatefulSet names for ingress/egress proxies are calculated
using Kubernetes name generator and the parent resource name
as a base.
The name generator also cuts the base, but has a higher max cap.
This commit fixes a bug where, if we get a shortened base back
from the generator, we cut off too little as the base that we
have cut will be passed into the generator again, which will
then itself cut less because the base is shorter- so we end up
with a too long name again.

to their tailnet.

Also adds various CRD related machinery to

This means that users who don't want to use the alpha
Connector custom resource don't have to install the Connector
CRD to their cluster.
For users who do want to use it the flow is:
- install the CRD
- install the operator (via Helm chart or using static manifests).
For Helm users set .values.enableConnector to true, for static
manifest users, set ENABLE_CONNECTOR to true in the static manifest.

`tailscaled` and `tailscale` expect the socket to be at
`/var/run/tailscale/tailscaled.sock`, however containerboot
would set up the socket at `/tmp/tailscaled.sock`. This leads to a
poor UX when users try to use any `tailscale` command as they
have to prefix everything with `--socket /tmp/tailscaled.sock`.

To improve the UX, this adds a symlink to
`/var/run/tailscale/tailscaled.sock` to point to `/tmp/tailscaled.sock`.

This approach has two benefits, 1 users are able to continue to use
existing scripts without this being a breaking change. 2. users are
able to use the `tailscale` CLI without having to add the `--socket` flag.

Change `MaskedPrefs` and `ApplyEdits` to support `FooSet` struct fields
that map to a nested struct of `ipn.Prefs` like `AutoUpdates`. Each
struct field in `MaskedPrefs` is just a bundle of more `Set` bool fields
or other structs. This allows you to have a `Set` flag for any
arbitrarily-nested field of `ipn.Prefs`.

Also, make `ApplyEdits` match fields between `Prefs` and `MaskedPrefs`
by name instead of order, to make it a bit less finicky. It's probably
slower but `ipn.ApplyEdits` should not be in any hot path.

As a result, `AutoUpdate.Check` and `AutoUpdate.Apply` fields don't
clobber each other when set individually.

Marwan Sulaiman b819f66eb1 tsweb: propagate RequestID via context and entire request
The recent addition of RequestID was only populated if the
HTTP Request had returned an error. This meant that the underlying
handler has no access to this request id and any logs it may have
emitted were impossible to correlate to that request id. Therefore,
this PR adds a middleware to generate request ids and pass them
through the request context. The tsweb.StdHandler automatically
populates this request id if the middleware is being used. Finally,
inner handlers can use the context to retrieve that same request id
and use it so that all logs and events can be correlated.

Marwan Sulaiman 2dc0645368 ipn/ipnlocal,cmd/tailscale: persist tailnet name in user profile
This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled
clients can use this value to disambiguate fast user switching from one tailnet
to another that are under the same exact login. We will also try to backfill
this information during backend starts and profile switches so that users don't
have to re-authenticate their profile. The first client to use this new
information is the CLI in 'tailscale switch -list' which now uses text/tabwriter
to display the ID, Tailnet, and Account. Since account names are ambiguous, we
allow the user to pass 'tailscale switch ID' to specify the exact tailnet they
want to switch to.

Aaron Klotz 855f79fad7 cmd/tailscaled, util/winutil: changes to process and token APIs in winutil
This PR changes the internal getTokenInfo function to use generics.
I also removed our own implementations for obtaining a token's user
and primary group in favour of calling the ones now available in
x/sys/windows.

Furthermore, I added two new functions for working with tokens, logon
session IDs, and Terminal Services / RDP session IDs.

I modified our privilege enabling code to allow enabling of multiple
privileges via one single function call.

Finally, I added the ProcessImageName function and updated the code in
tailscaled_windows.go to use that instead of directly calling the
underlying API.

All of these changes will be utilized by subsequent PRs pertaining to
this issue.

Now that 1.54 has released, and the new web client will be included in

all 1.55 unstable builds, and then eventually the 1.56 build, will work
without setting the node capability.

The web client still requires the "webclient" user pref, so this does
NOT mean that the web client will be on by default for all devices.
