Nick Khyl 36b7449fea ipn/ipnlocal: rebuild allowed suggested exit nodes when syspolicy changes 
In this PR, we update LocalBackend to rebuild the set of allowed suggested exit nodes whenever
the AllowedSuggestedExitNodes syspolicy setting changes. Additionally, we request a new suggested
exit node when this occurs, enabling its use if the ExitNodeID syspolicy setting is set to auto:any.

kube/{kubeapi,kubeclient},ipn/store/kubestore,cmd/{containerboot,k8s-operator}: emit kube store Events (#14112) 
Adds functionality to kube client to emit Events.
Updates kube store to emit Events when tailscaled state has been loaded, updated or if any errors where
encountered during those operations.
This should help in cases where an error related to state loading/updating caused the Pod to crash in a loop-
unlike logs of the originally failed container instance, Events associated with the Pod will still be
accessible even after N restarts.

Brad Fitzpatrick da70a84a4b ipn/ipnlocal: fix build, remove another Notify.BackendLogID reference that crept in 
I merged 5cae7c51bf (removing Notify.BackendLogID) and 93db503565

Brad Fitzpatrick 93db503565 ipn/ipnlocal: add IPN Bus NotifyRateLimit watch bit NotifyRateLimit 
Limit spamming GUIs with boring updates to once in 3 seconds, unless
the notification is relatively interesting and the GUI should update
immediately.

This is basically @barnstar's #14119 but with the logic moved to be
per-watch-session (since the bit is per session), rather than
globally. And this distinguishes notable Notify messages (such as
state changes) and makes them send immediately.

client/tailscale,ipn/{ipnlocal,localapi}: add a pre-shutdown localAPI endpoint that terminates control connections. (#14028) 
Adds a /disconnect-control local API endpoint that just shuts down control client.
This can be run before shutting down an HA subnet router/app connector replica - it will ensure
that all connection to control are dropped and control thus considers this node inactive and tells
peers to switch over to another replica. Meanwhile the existing connections keep working (assuming
that the replica is given some graceful shutdown period).

This adds a new generic result type (motivated by golang/go#70084) to
try it out, and uses it in the new lineutil package (replacing the old

iterators over results of []byte, if errors might happen at runtime.

Nick Khyl e815ae0ec4 util/syspolicy, ipn/ipnlocal: update syspolicy package to utilize syspolicy/rsop 
In this PR, we update the syspolicy package to utilize syspolicy/rsop under the hood,
and remove syspolicy.CachingHandler, syspolicy.windowsHandler and related code
which is no longer used.

We mark the syspolicy.Handler interface and RegisterHandler/SetHandlerForTest functions
as deprecated, but keep them temporarily until they are no longer used in other repos.

We also update the package to register setting definitions for all existing policy settings
and to register the Registry-based, Windows-specific policy stores when running on Windows.

Finally, we update existing internal and external tests to use the new API and add a few more
tests and benchmarks.

Nick Khyl 874db2173b ipn/{ipnauth,ipnlocal,ipnserver}: send the auth URL to the user who started interactive login 
We add the ClientID() method to the ipnauth.Actor interface and updated ipnserver.actor to implement it.
This method returns a unique ID of the connected client if the actor represents one. It helps link a series
of interactions initiated by the client, such as when a notification needs to be sent back to a specific session,
rather than all active sessions, in response to a certain request.

We also add LocalBackend.WatchNotificationsAs and LocalBackend.StartLoginInteractiveAs methods,
which are like WatchNotifications and StartLoginInteractive but accept an additional parameter
specifying an ipnauth.Actor who initiates the operation. We store these actor identities in
watchSession.owner and LocalBackend.authActor, respectively,and implement LocalBackend.sendTo
and related helper methods to enable sending notifications to watchSessions associated with actors
(or, more broadly, identifiable recipients).

We then use the above to change who receives the BrowseToURL notifications:
 - For user-initiated, interactive logins, the notification is delivered only to the user who initiated the
   process. If the initiating actor represents a specific connected client, the URL notification is sent back
   to the same LocalAPI client that called StartLoginInteractive. Otherwise, the notification is sent to all
   clients connected as that user.
   Currently, we only differentiate between users on Windows, as it is inherently a multi-user OS.
 - In all other cases (e.g., node key expiration), we send the notification to all connected users.

When a rotation signature chain reaches a certain size, remove the
oldest rotation signature from the chain before wrapping it in a new
rotation signature.

Since all previous rotation signatures are signed by the same wrapping
pubkey (node's own tailnet lock key), the node can re-construct the
chain, re-signing previous rotation signatures. This will satisfy the
existing certificate validation logic.

cli: implement `tailscale dns status` (#13353) 
Updates tailscale/tailscale#13326

This PR begins implementing a `tailscale dns` command group in the Tailscale CLI. It provides an initial implementation of `tailscale dns status` which dumps the state of the internal DNS forwarder.

Two new endpoints were added in LocalAPI to support the CLI functionality:

- `/netmap`: dumps a copy of the last received network map (because the CLI shouldn't have to listen to the ipn bus for a copy)
- `/dns-osconfig`: dumps the OS DNS configuration (this will be very handy for the UI clients as well, as they currently do not display this information)

My plan is to implement other subcommands mentioned in tailscale/tailscale#13326, such as `query`, in later PRs.

Nick Khyl 5bc9fafab8 ipn/ipnlocal: always send auth URL notifications when a user requests interactive login 
This PR changes how LocalBackend handles interactive (initiated via StartLoginInteractive) and non-interactive (e.g., due to key expiration) logins,
and when it sends the authURL to the connected clients.

Specifically,
 - When a user initiates an interactive login by clicking Log In in the GUI, the LocalAPI calls StartLoginInteractive.
   If an authURL is available and hasn't expired, we immediately send it to all connected clients, suggesting them to open that URL in a browser.
   Otherwise, we send a login request to the control plane and set a flag indicating that an interactive login is in progress.
 - When LocalBackend receives an authURL from the control plane, we check if it differs from the previous one and whether an interactive login
   is in progress. If either condition is true, we notify all connected clients with the new authURL and reset the interactive login flag.

We reset the auth URL and flags upon a successful authentication, when a different user logs in and when switching Tailscale login profiles.

Finally, we remove the redundant dedup logic added to WatchNotifications in #12096 and revert the tests to their original state to ensure that
calling StartLoginInteractive always produces BrowseToURL notifications, either immediately or when the authURL is received from the control plane.

Nick Khyl b48c8db69c ipn/ipnlocal: set WantRunning upon an interactive login, but not during a seamless renewal or a profile switch 
The LocalBackend's state machine starts in NoState and soon transitions to NeedsLogin if there's no auto-start profile,
with the profileManager starting with a new empty profile. Notably, entering the NeedsLogin state blocks engine updates.
We expect the user to transition out of this state by logging in interactively, and we set WantRunning to true when
controlclient enters the StateAuthenticated state.

While our intention is correct, and completing an interactive login should set WantRunning to true, our assumption
that logging into the current Tailscale profile is the only way to transition out of the NeedsLogin state is not accurate.
Another common transition path includes an explicit profile switch (via LocalBackend.SwitchProfile) or an implicit switch
when a Windows user connects to the backend. This results in a bug where WantRunning is set to true even when it was
previously set to false, and the user expressed no intention of changing it.

A similar issue occurs when switching from (sic) a Tailnet that has seamlessRenewalEnabled, regardless of the current state
of the LocalBackend's state machine, and also results in unexpectedly set WantRunning. While this behavior is generally
undesired, it is also incorrect that it depends on the control knobs of the Tailnet we're switching from rather than
the Tailnet we're switching to. However, this issue needs to be addressed separately.

This PR updates LocalBackend.SetControlClientStatus to only set WantRunning to true in response to an interactive login
as indicated by a non-empty authURL.

Nick Khyl 80b2b45d60 ipn/ipnlocal: refactor and cleanup profileManager 
In preparation for multi-user and unattended mode improvements, we are
refactoring and cleaning up `ipn/ipnlocal.profileManager`. The concept of the
"current user", which is only relevant on Windows, is being deprecated and will
soon be removed to allow more than one Windows user to connect and utilize
`LocalBackend` according to that user's access rights to the device and specific
Tailscale profiles.

We plan to pass the user's identity down to the `profileManager`, where it can
be used to determine the user's access rights to a given `LoginProfile`. While
the new permission model in `ipnauth` requires more work and is currently
blocked pending PR reviews, we are updating the `profileManager` to reduce its
reliance on the concept of a single OS user being connected to the backend at
the same time.

We extract the switching to the default Tailscale profile, which may also
trigger legacy profile migration, from `profileManager.SetCurrentUserID`. This
introduces `profileManager.DefaultUserProfileID`, which returns the default
profile ID for the current user, and `profileManager.SwitchToDefaultProfile`,
which is essentially a shorthand for `pm.SwitchProfile(pm.DefaultUserProfileID())`.
Both methods will eventually be updated to accept the user's identity and
utilize that user's default profile.

We make access checks more explicit by introducing the `profileManager.checkProfileAccess`
method. The current implementation continues to use `profileManager.currentUserID`
and `LoginProfile.LocalUserID` to determine whether access to a given profile
should be granted. This will be updated to utilize the `ipnauth` package and the
new permissions model once it's ready. We also expand access checks to be used
more widely in the `profileManager`, not just when switching or listing
profiles. This includes access checks in methods like `SetPrefs` and, most notably,
`DeleteProfile` and `DeleteAllProfiles`, preventing unprivileged Windows users
from deleting Tailscale profiles owned by other users on the same device,
including profiles owned by local admins.

We extract `profileManager.ProfilePrefs` and `profileManager.SetProfilePrefs`
methods that can be used to get and set preferences of a given `LoginProfile` if
`profileManager.checkProfileAccess` permits access to it.

We also update `profileManager.setUnattendedModeAsConfigured` to always enable
unattended mode on Windows if `Prefs.ForceDaemon` is true in the current
`LoginProfile`, even if `profileManager.currentUserID` is `""`. This facilitates
enabling unattended mode via `tailscale up --unattended` even if
`tailscale-ipn.exe` is not running, such as when a Group Policy or MDM-deployed
script runs at boot time, or when Tailscale is used on a Server Code or otherwise
headless Windows environments. See #12239, #2137, #3186 and
https://github.com/tailscale/tailscale/pull/6255#issuecomment-2016623838 for

Nick Khyl 961ee321e8 ipn/{ipnauth,ipnlocal,ipnserver,localapi}: start baby step toward moving access checks from the localapi.Handler to the LocalBackend 
Currently, we use PermitRead/PermitWrite/PermitCert permission flags to determine which operations are allowed for a LocalAPI client.
These checks are performed when localapi.Handler handles a request. Additionally, certain operations (e.g., changing the serve config)
requires the connected user to be a local admin. This approach is inherently racey and is subject to TOCTOU issues.
We consider it to be more critical on Windows environments, which are inherently multi-user, and therefore we prevent more than one
OS user from connecting and utilizing the LocalBackend at the same time. However, the same type of issues is also applicable to other
platforms when switching between profiles that have different OperatorUser values in ipn.Prefs.

We'd like to allow more than one Windows user to connect, but limit what they can see and do based on their access rights on the device
(e.g., an local admin or not) and to the currently active LoginProfile (e.g., owner/operator or not), while preventing TOCTOU issues on Windows
and other platforms. Therefore, we'd like to pass an actor from the LocalAPI to the LocalBackend to represent the user performing the operation.
The LocalBackend, or the profileManager down the line, will then check the actor's access rights to perform a given operation on the device
and against the current (and/or the target) profile.

This PR does not change the current permission model in any way, but it introduces the concept of an actor and includes some preparatory
work to pass it around. Temporarily, the ipnauth.Actor interface has methods like IsLocalSystem and IsLocalAdmin, which are only relevant
to the current permission model. It also lacks methods that will actually be used in the new model. We'll be adding these gradually in the next
PRs and removing the deprecated methods and the Permit* flags at the end of the transition.

Anton Tolchanov 151b77f9d6 cmd/tl-longchain: tool to re-sign nodes with long rotation signatures 
In Tailnet Lock, there is an implicit limit on the number of rotation
signatures that can be chained before the signature becomes too long.

This program helps tailnet admins to identify nodes that have signatures
with long chains and prints commands to re-sign those node keys with a
fresh direct signature. It's a temporary mitigation measure, and we will
remove this tool as we design and implement a long-term approach for
rotation signatures.

Example output:

```
2024/08/20 18:25:03 Self: does not need re-signing
2024/08/20 18:25:03 Visible peers with valid signatures:

2024/08/20 18:25:03 Peer xxx4.yy.ts.net. (100.85.253.53) nodeid=nmZfVygzkB21KTM59, current signature kind=rotation: chain length 4, printing command to re-sign
tailscale lock sign nodekey:530bddbfbe69e91fe15758a1d6ead5337aa6307e55ac92dafad3794f8b3fc661 tlpub:4bf07597336703395f2149dce88e7c50dd8694ab5bbde3d7c2a1c7b3e231a3c2
```

To support this, the NetworkLockStatus localapi response now includes
information about signatures of all peers rather than just the invalid
ones. This is not displayed by default in `tailscale lock status`, but
will be surfaced in `tailscale lock status --json`.

clientupdate: return true for CanAutoUpdate for macsys (#12746) 
While `clientupdate.Updater` won't be able to apply updates on macsys,
we use `clientupdate.CanAutoUpdate` to gate the EditPrefs endpoint in
localAPI. We should allow the GUI client to set AutoUpdate.Apply on
macsys for it to properly get reported to the control plane. This also
allows the tailnet-wide default for auto-updates to propagate to macsys
clients.

health: include DERP region name in bad derp notifications (#12530) 
Fixes tailscale/corp#20971

We added some Warnables for DERP failure situations, but their Text currently spits out the DERP region ID ("10") in the UI, which is super ugly. It would be better to provide the RegionName of the DERP region that is failing. We can do so by storing a reference to the last-known DERP map in the health package whenever we fetch one, and using it when generating the notification text.

This way, the following message...

> Tailscale could not connect to the relay server '10'. The server might be temporarily unavailable, or your Internet connection might be down.

becomes:

> Tailscale could not connect to the 'Seattle' relay server. The server might be temporarily unavailable, or your Internet connection might be down.

which is a lot more user-friendly.

health: begin work to use structured health warnings instead of strings, pipe changes into ipn.Notify (#12406) 
Updates tailscale/tailscale#4136

This PR is the first round of work to move from encoding health warnings as strings and use structured data instead. The current health package revolves around the idea of Subsystems. Each subsystem can have (or not have) a Go error associated with it. The overall health of the backend is given by the concatenation of all these errors.

This PR polishes the concept of Warnable introduced by @bradfitz a few weeks ago. Each Warnable is a component of the backend (for instance, things like 'dns' or 'magicsock' are Warnables). Each Warnable has a unique identifying code. A Warnable is an entity we can warn the user about, by setting (or unsetting) a WarningState for it. Warnables have:

- an identifying Code, so that the GUI can track them as their WarningStates come and go
- a Title, which the GUIs can use to tell the user what component of the backend is broken
- a Text, which is a function that is called with a set of Args to generate a more detailed error message to explain the unhappy state

Additionally, this PR also begins to send Warnables and their WarningStates through LocalAPI to the clients, using ipn.Notify messages. An ipn.Notify is only issued when a warning is added or removed from the Tracker.

In a next PR, we'll get rid of subsystems entirely, and we'll start using structured warnings for all errors affecting the backend functionality.

Adrian Dewhurst 0219317372 ipn/ipnlocal: improve sticky last suggestion 
The last suggested exit node needs to be incorporated in the decision
making process when a new suggestion is requested, but currently it is
not quite right: it'll be used if the suggestion code has an error or a
netmap is unavailable, but it won't be used otherwise.

Instead, this makes the last suggestion into a tiebreaker when making a
random selection between equally-good options. If the last suggestion
does not make it to the final selection pool, then a different
suggestion will be made.

Since LocalBackend.SuggestExitNode is back to being a thin shim that
sets up the parameters to suggestExitNode, it no longer needs a test.
Its test was unable to be comprehensive anyway as the code being tested
contains an uncontrolled random number generator.

Adrian Dewhurst 3bf2bddbb5 ipn/ipnlocal: improve testability of random node selection 
In order to test the sticky last suggestion code, a test was written for
LocalBackend.SuggestExitNode but it contains a random number generator
which makes writing comprehensive tests very difficult. This doesn't
change how the last suggestion works, but it adds some infrastructure to
make that easier in a later PR.

This adds func parameters for the two randomized parts: breaking ties
between DERP regions and breaking ties between nodes. This way tests can
validate the entire list of tied options, rather than expecting a
particular outcome given a particular random seed.

As a result of this, the global random number generator can be used
rather than seeding a local one each time.

In order to see the tied nodes for the location based (i.e. Mullvad)
case, pickWeighted needed to return a slice instead of a single
arbitrary option, so there is a small change in how that works.

Anton Tolchanov 01847e0123 ipn/ipnlocal: discard node keys that have been rotated out 
A non-signing node can be allowed to re-sign its new node keys following
key renewal/rotation (e.g. via `tailscale up --force-reauth`). To be
able to do this, node's TLK is written into WrappingPubkey field of the
initial SigDirect signature, signed by a signing node.

The intended use of this field implies that, for each WrappingPubkey, we
typically expect to have at most one active node with a signature
tracing back to that key. Multiple valid signatures referring to the
same WrappingPubkey can occur if a client's state has been cloned, but
it's something we explicitly discourage and don't support:
https://tailscale.com/s/clone

This change propagates rotation details (wrapping public key, a list
of previous node keys that have been rotated out) to netmap processing,
and adds tracking of obsolete node keys that, when found, will get
filtered out.

doesn't. But Start doesn't tell us that. So cheat a bit and a put the
information about whether there's a current NodeKey in the ipn.Status.
It used to be accessible over LocalAPI via GetPrefs as a private key but
we removed that for security. But a bool is fine.

So then only call StartLoginInteractive if that bool is false and don't
do it in the WatchIPNBus loop.

Nick Khyl caa3d7594f ipn/ipnlocal, net/tsdial: plumb routes into tsdial and use them in UserDial 
We'd like to use tsdial.Dialer.UserDial instead of SystemDial for DNS over TCP.
This is primarily necessary to properly dial internal DNS servers accessible
over Tailscale and subnet routes. However, to avoid issues when switching
between Wi-Fi and cellular, we need to ensure that we don't retain connections
to any external addresses on the old interface. Therefore, we need to determine
which dialer to use internally based on the configured routes.

This plumbs routes and localRoutes from router.Config to tsdial.Dialer,
and updates UserDial to use either the peer dialer or the system dialer,
depending on the network address and the configured routes.

We'll still ultimately need the stringified form for the CLI and
LocalAPI for compatibility but we'll next convert all these warnings
into Warnables that have severity levels and such, and legacy
stringification will just be something each Warnable thing can do.

Reset dial plan when switching profile (#11933) 
When switching profile, the server URL can change (e.g.
because of switching to a self-hosted headscale instance).

If it is not reset here, dial plans returned by old
server (e.g. tailscale control server) will be used to
connect to new server (e.g. self-hosted headscale server),
and the register request will be blocked by it until
timeout, leading to very slow profile switches.

The goal is to move more network state accessors to netmon.Monitor

we need to make sure the one netmon.Monitor is plumbed everywhere.

Some notable bits:

* tsdial.NewDialer is added, taking a now-required netmon

* because a tsdial.Dialer always has a netmon, anything taking both
  a Dialer and a NetMon is now redundant; take only the Dialer and
  get the NetMon from that if/when needed.

* netmon.NewStatic is added, primarily for tests
