This test ostensibly checks whether we record an error metric if a packet
is dropped because the network is down, but the network connectivity is
irrelevant -- the send error is actually because the arguments to Send()
are invalid:
RebindingUDPConn.WriteWireGuardBatchTo:
[unexpected] offset (0) != Geneve header length (8)
This patch changes the test so we try to send a valid packet, and we
verify this by sending it once before taking the network down. The new
error is:
magicsock: network down
which is what we're trying to test.
We then test sending an invalid payload as a separate test case.

endpointState is used for tracking UDP direct connection candidate
addresses. If it contains a DERP addr, then direct connection path
discovery will always send a wasteful disco ping over it. Additionally,
CLI "tailscale ping" via peer relay will race over DERP, leading to a
misleading result if pong arrives via DERP first.
Disco pongs arriving via DERP never influence path selection. Disco
ping/pong via DERP only serves "tailscale ping" reporting.

When you say --features=foo,bar, that was supposed to mean
to only show features "foo" and "bar" in the table.
But it was also being used as the set of all features that are
omittable, which was wrong, leading to misleading numbers
when --features was non-empty.

The Unix implementation of doExec propagates error codes by virtue of
the fact that it does an execve; the replacement binary will return the
exit code.
On non-Unix, we need to simulate these semantics by checking for an
ExitError and, when present, passing that value on to os.Exit.
We also add error handling to the doExec call for the benefit of
handling any errors where doExec fails before being able to execute
the desired binary.

Extend the client state management to generate a hardware attestation
key if none exists.
Extend MapRequest with HardwareAttestationKey{,Signature} fields that
optionally contain the public component of the hardware attestation key
and a signature of the node's node key using it. This will be used by
control to associate hardware attesation keys with node identities on a
TOFU basis.

This commit adds a new method to the tsnet.Server type named `Logger`
that returns the underlying logtail instance's Logf method.
This is intended to be used within the Kubernetes operator to wrap its
existing logger in a way such that operator specific logs can also be
sent to control for support & debugging purposes.

Nowadays it's the caller (func control) that curries the logf/netmon

Removes ACL edits from e2e tests in favour of trying to simplify the

logic as much as possible. Also aims to fit in with the requirements
that will generally be filled anyway for most devs working on the

This adds a file that's not compiled by default that exists just to
make it easier to do binary size checks, probing what a binary would
be like if it included reflect methods (as used by html/template, etc).
As an example, once tailscaled uses reflect.Type.MethodByName(non-const-string) anywhere,
the build jumps up by 14.5 MB:
$ GOOS=linux GOARCH=amd64 ./tool/go build -tags=ts_include_cli,ts_omit_webclient,ts_omit_systray,ts_omit_debugeventbus -o before ./cmd/tailscaled
$ GOOS=linux GOARCH=amd64 ./tool/go build -tags=ts_include_cli,ts_omit_webclient,ts_omit_systray,ts_omit_debugeventbus,ts_debug_forcereflect -o after ./cmd/tailscaled
$ ls -l before after
-rwxr-xr-x@ 1 bradfitz staff 41011861 Sep 9 07:28 before
-rwxr-xr-x@ 1 bradfitz staff 55610948 Sep 9 07:29 after
This is particularly pronounced with large deps like the AWS SDK. If you compare using ts_omit_aws:
-rwxr-xr-x@ 1 bradfitz staff 38284771 Sep 9 07:40 no-aws-no-reflect
-rwxr-xr-x@ 1 bradfitz staff 45546491 Sep 9 07:41 no-aws-with-reflect
That means adding AWS to a non-reflect binary adds 2.7 MB but adding
AWS to a reflect binary adds 10 MB.

Fix "file not found" errors when WebDAV clients access files/dirs inside
directories with spaces.
The issue occurred because StatCache was mixing URL-escaped and
unescaped paths, causing cache key mismatches.
Specifically, StatCache.set() parsed WebDAV responses containing
URL-escaped paths (ex. "Dir%20Space/file1.txt") and stored them
alongside unescaped cache keys (ex. "Dir Space/file1.txt").
This mismatch prevented StatCache.get() from correctly determining whether
a child file existed.
See https://github.com/tailscale/tailscale/issues/13632#issuecomment-3243522449
for the full explanation of the issue.
The decision to keep all paths references unescaped inside the StatCache
is consistent with net/http.Request.URL.Path and rewrite.go (sole consumer)
Update unit test to detect this directory space mishandling.
