I added a RemoveAll() method on tka.Chonk in #17946, but it's only used
in the node to purge local AUMs. We don't need it in the SQLite storage,
which currently implements tka.Chonk, so move it to CompactableChonk
instead.
Also add some automated tests, as a safety net.

The REST API does not return a node name
with a trailing dot, while the internal node name
reported in the netmap does have one.
In order to be consistent with the API,
strip the dot when recording node information.

Perform a path check first before attempting exec of `true`.
Try /usr/bin/true first, as that is now and increasingly so, the more
common and more portable path.
Fixes tests on macOS arm64 where exec was returning a different kind of
path error than previously checked.

DA protection is not super helpful because we don't set an authorization
password on the key. But if authorization fails for other reasons (like
TPM being reset), we will eventually cause DA lockout with tailscaled
trying to load the key. DA lockout then leads to (1) issues for other
processes using the TPM and (2) the underlying authorization error being
masked in logs.

This patch changes the behaviour of `tailscale lock log --json` to make
it more useful for users. It also introduces versioning of our JSON output.
## Changes to `tailscale lock log --json`
Previously this command would print the hash and base64-encoded bytes of
each AUM, and users would need their own CBOR decoder to interpret it in
a useful way:
```json
[
{
"Hash": [
80,
136,
151,
…
],
"Change": "checkpoint",
"Raw": "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"
}
]
```
Now we print the AUM in an expanded form that can be easily read by scripts,
although we include the raw bytes for verification and auditing.
```json
{
"SchemaVersion": "1",
"Messages": [
{
"Hash": "KCEJPRKNSXJG2TPH3EHQRLJNLIIK2DV53FUNPADWA7BZJWBDRXZQ",

}

}
```
This output was previously marked as unstable, and it wasn't very useful,
so changing it should be fine.
## Versioning our JSON output
This patch introduces a way to version our JSON output on the CLI, so we
can make backwards-incompatible changes in future without breaking existing
scripts or integrations.
You can run this command in two ways:
```
tailscale lock log --json
tailscale lock log --json=1
```
Passing an explicit version number allows you to pick a specific JSON schema.
If we ever want to change the schema, we increment the version number and
users must opt-in to the new output.
A bare `--json` flag will always return schema version 1, for compatibility
with existing scripts.

This adds the --proxy-protocol flag to 'tailscale serve' and
'tailscale funnel', which tells the Tailscale client to prepend a PROXY
protocol[1] header when making connections to the proxied-to backend.
I've verified that this works with our existing funnel servers without
additional work, since they pass along source address information via
PeerAPI already.

Remove the State enum (StateNew, StateNotAuthenticated, etc.) from
controlclient and replace it with two explicit boolean fields:
- LoginFinished: indicates successful authentication
- Synced: indicates we've received at least one netmap
This makes the state more composable and easier to reason about, as
multiple conditions can be true independently rather than being
encoded in a single enum value.
The State enum was originally intended as the state machine for the
whole client, but that abstraction moved to ipn.Backend long ago.
This change continues moving away from the legacy state machine by
representing state as a combination of independent facts.
Also adds test helpers in ipnlocal that check independent, observable
facts (hasValidNetMap, needsLogin, etc.) rather than relying on
derived state enums, making tests more robust.

The key.NewEmptyHardwareAttestationKey hook returns a non-nil empty
attestationKey, which means that the nil check in Clone doesn't trigger
and proceeds to try and clone an empty key. Check IsZero instead to
reduce log spam from Clone.
As a drive-by, make tpmAvailable check a sync.Once because the result
won't change.

Most /etc/os-release files set the VERSION_ID to a `MAJOR.MINOR`
string, but we were trying to compare this numerically against a major
version number. I can only assume that Linux Mint used switched from a
plain integer, since shells only do integer comparisons.
This patch extracts a VERSION_MAJOR from the VERSION_ID using
parameter expansion and unifies all the other ad-hoc comparisons to
use it.

LinkChangeLogLimiter keeps a subscription to track rate limits for log
messages. But when its context ended, it would exit the subscription loop,
leaving the subscriber still alive. Ensure the subscriber gets cleaned up
when the context ends, so we don't stall event processing.

On the corp tailnet (using Mullvad exit nodes + bunch of expired
devices + subnet routers), these were generating big ~35 KB blobs of
logging regularly.
This logging shouldn't even exist at this level, and should be rate
limited at a higher level, but for now as a bandaid, make it less
spammy.

When TS_LOG_TARGET is set to an invalid URL, url.Parse returns an error

Now we check the error from url.Parse and log a helpful message while

As a baby step towards eventbus-ifying controlclient, make the

This also means callers that don't care (like this network lock test,

This commit replaces usage of local.Client in net/udprelay with DERPMap
plumbing over the eventbus. This has been a longstanding TODO. This work
was also accelerated by a memory leak in net/http when using
local.Client over long periods of time. So, this commit also addresses
said leak.

updates tailscale/corp#31571
It appears that on the latest macOS, iOS and tVOS versions, the work
that netns is doing to bind outgoing connections to the default interface (and all
of the trimmings and workarounds in netmon et al that make that work) are
not needed. The kernel is extension-aware and doing nothing, is the right
thing. This is, however, not the case for tailscaled (which is not a
special process).
To allow us to test this assertion (and where it might break things), we add a
new node cap that turns this behaviour off only for network-extension equipped clients,
making it possible to turn this off tailnet-wide, without breaking any tailscaled
macos nodes.
