Reword comments and docs that still named the removed gRPC stack, rename
the GRPCSortable test interface, and drop the dead gRPC port note from the
dev README.
Unit-test formatOutput across json/json-line/yaml for every printed API
type and exercise the node table renderers, whose manual key/IP decode
had no coverage. These paths only ran in -o json before.
Generated API types have a pointer-receiver MarshalJSON that omits unset
optional fields. The CLI marshalled them by value, so stdlib reflection
called Opt*.MarshalJSON directly and failed with "unexpected end of JSON
input", breaking every -o json/-o yaml command. Make values addressable
first so the generated marshaler runs.
A CLI command issued right after startup can beat headscale to binding
its unix socket. Retry the dial until the CLI timeout, matching the old
blocking gRPC dial, instead of failing on a missing socket file.
Drop grpc_listen_addr/grpc_allow_insecure config, the gRPC auth integration
tests, GrpcSocketDialer, and stale gRPC comments now that the API is HTTP-only.
Serve the API over the unix socket (auth bypassed; socket permissions are the
trust boundary) and convert every CLI command from the gRPC client to the
generated ogen client. Remote CLI now uses the HTTP API URL.
Prints the tailscale versions integration tests use, with optional
filter and format flags. Source of truth stays in hscontrol/capver;
CI shells out to this instead of duplicating the version list in
YAML.
Examples:
hi list-versions
hi list-versions --set=must --exclude=head
hi list-versions --set=all --format=json
Every Go-identifier reference in // and /* */ comments now uses
godoc's [Name] linking syntax so pkg.go.dev and `go doc` render
them as clickable cross-references. No behaviour change.
Pattern applied across the tree:
In-package [Foo], [Foo.Bar]
Cross-package [pkg.Foo], [pkg.Foo.Bar]
Stdlib [netip.Prefix], [errors.Is], [context.Context]
Tailscale [tailcfg.MapResponse], [tailcfg.Node.CapMap],
[tailcfg.NodeAttrSuggestExitNode]
Skip rules:
- File:line refs left as plain text
- HuJSON wire keys inside backtick raw strings untouched
- ACL/policy syntax tokens (tag:foo, autogroup:self, ...) not Go
symbols, left as plain text
- JSON/OIDC wire keys, gorm tags, RFC IPv6 placeholders, markdown
link tags, decorative dividers — all left as-is
Constants the operator/test reader benefits from centralising.
Tests stay verbatim (the .golangci.yaml goconst tune skips them);
extraction here applies only where the same literal acts as
shared vocabulary across files.
cmd/headscale/cli/strings.go (new)
Cobra subcommand verbs and aliases shared by every list / show
/ new / delete / expire command across api_key, nodes, policy,
preauthkeys, users — plus the Result / Created / Expiration
column headers used in printOutput maps.
hscontrol/templates/design.go
cssBorderHS, cssBreakWord, cssCenter, cssOverflowWrap — shared
styles applied across design.go, ping.go, register_confirm.go.
spaceS already existed; switch raw "0.5rem" literals to it.
integration/hsic/hsic.go
binHeadscale, flagOutput, acceptJSON — names invoked across
hsic.go and config.go.
integration/tsic/tsic.go
tailscaleBin — used across docker exec call sites.
Anonymous Hub pulls trip the 100/6h IP cap on shared CI runners, turning
into singleton FAIL reports whenever the runner egress IP crosses the
quota. Route every pull through Docker Hub credentials when present, and
retry transient errors with backoff. tsic and hi use the same helper so
both surfaces honour ~/.docker/config.json and the GHA secrets.
Tailscale models the randomize-client-port toggle as a top-level
field on the ACL policy. Headscale now matches that shape: the
server-config randomize_client_port key is removed, the toggle
lives in the policy file as randomizeClientPort, and per-node
opt-in via nodeAttrs is also supported.
Operators upgrading from a config-set randomize_client_port hit
depr.fatalWithHint at startup, which prints the deprecation message
and points at the new policy field rather than silently dropping
the toggle. The default carries over (false) so operators who never
set it are unaffected. config-example.yaml ships a REMOVED stanza
showing the migration.
types/node.go drops the cfg.RandomizeClientPort read from
TailNode -- the cap is now policy-driven through compileNodeAttrs
and the tail_test.go expectations follow.
v2 silently dropped policy.tests, so a policy that contradicted its
own assertions still applied. Resolve src/dst via the existing Alias
machinery, walk the compiled global filter rules (acls and grants
both contribute), and run on every user-write boundary: SetPolicy,
the file watcher, and `headscale policy check`. A failing test
rejects the write before it mutates live state.
Boot-time reload skips evaluation; an already-stored policy that
references a deleted user shouldn't lock the server out.
`headscale policy check` is a thin frontend for the new CheckPolicy
gRPC method. The server-side handler builds a fresh PolicyManager
from the request bytes and the state's live users/nodes, runs
SetPolicy on the sandbox so the tests block executes, and returns
the result through gRPC status. No persistence, no policy_mode
coupling. --bypass-grpc-and-access-database-directly opens the DB
directly when the server is not running.
cmd/headscale/cli/root.go no longer special-cases `policy check` in
init() (the early return from PR #2580 broke --config registration
and viper priming for --bypass).
integration/cli_policy_test.go covers policy_mode={file,database} x
fixture={acl-only, acl+passing-tests, acl+failing-tests} x
bypass={false,true} = 12 rows.
Updates #1803

Move the headscale vendorHash out of flake.nix into a content-
addressed flakehashes.json maintained by a small Go tool. The
schema and goModFingerprint algorithm mirror upstream tailscale's
tool/updateflakes so a future shared library extraction is trivial.
vendorhash check verifies flakehashes.json against the current
go.mod/go.sum. Hot path is a sha256 over those two files, so
re-runs without input change are essentially free; only an actual
fingerprint drift triggers go mod vendor + nardump.SRI.
vendorhash update recomputes both fields and rewrites the JSON.
The nix-vendor-sri devShell shim now wraps it.
Add --bypass-grpc-and-access-database-directly to policy check so
the new ambiguous-user validator runs against the live user list.
Without the flag, policy check stays a syntax-only check and the
success message says so.
Updates #3160
dev derives additional ports from --port + offsets (metrics, gRPC,
debug). A --port near uint16 max would overflow silently; add up-front
validation that rejects values that would push derived ports over 65535.
Updates #3157
Add a lightweight dev tool that starts a headscale server on localhost
with a pre-created user and pre-auth key, ready for connecting real
tailscale nodes via mts.
The tool builds the headscale binary, writes a minimal dev config
(SQLite, public DERP, debug logging), starts the server as a
subprocess, and prints a banner with the server URL, auth key, and
mts usage instructions.
Usage: go run ./cmd/dev
make dev-server
Replace zcache with golang-lru/v2/expirable for both the state auth
cache and the OIDC state cache. Add tuning.register_cache_max_entries
(default 1024) to cap the number of pending registration entries.
Introduce types.RegistrationData to replace caching a full *Node;
only the fields the registration callback path reads are retained.
Remove the dead HSDatabase.regCache field. Drop zgo.at/zcache/v2
from go.mod.
Generalise the registration pipeline to a more general auth pipeline
supporting both node registrations and SSH check auth requests.
Rename RegistrationID to AuthID, unexport AuthRequest fields, and
introduce AuthVerdict to unify the auth finish API.
Add the urlParam generic helper for extracting typed URL parameters
from chi routes, used by the new auth request handler.
Updates #1850
Add --disable flag to "headscale nodes expire" CLI command and
disable_expiry field handling in the gRPC API to allow disabling
key expiry for nodes. When disabled, the node's expiry is set to
NULL and IsExpired() returns false.
The CLI follows the new grpcRunE/RunE/printOutput patterns
introduced in the recent CLI refactor.
Also fix NodeSetExpiry to persist directly to the database instead
of going through persistNodeToDB which omits the expiry field.
Fixes#2681

Remove dead if-resp-nil checks in tagCmd and approveRoutesCmd; gRPC
returns either an error or a valid response, never (nil, nil).
Rename HasMachineOutputFlag to hasMachineOutputFlag since it has a
single internal caller in root.go.
Add bypassDatabase() to consolidate the repeated LoadServerConfig +
NewHeadscaleDatabase pattern in getPolicy and setPolicy.
Replace os.Open + io.ReadAll with os.ReadFile in setPolicy and
checkPolicy, removing the manual file-handle management.
Move errMissingParameter from users.go to utils.go alongside the
other shared sentinel errors; the variable is referenced by
api_key.go and preauthkeys.go.
Move the Error constant-error type from debug.go to mockoidc.go,
its only consumer.
Replace five hardcoded "2006-01-02 15:04:05" strings with the
HeadscaleDateTimeFormat constant already defined in utils.go.
Replace two literal 10 base arguments to strconv.FormatUint with
util.Base10 to match the convention in api_key.go and nodes.go.
Flags registered on a cobra.Command cannot fail to read at runtime;
GetString/GetUint64/GetStringSlice only error when the flag name is
unknown. The error-handling blocks for these calls are unreachable
dead code.
Adopt the value, _ := pattern already used in api_key.go,
preauthkeys.go and users.go, removing ~40 lines of dead code from
nodes.go and debug.go.
The --namespace flag on nodes list/register and debug create-node was
never wired to the --user flag, so its value was silently ignored.
Remove it along with the deprecateNamespaceMessage constant.
Also remove the namespace/ns command aliases on users and
machine/machines aliases on nodes, which have been deprecated since
the naming changes in 0.23.0.
Add expirationFromFlag helper that parses the --expiration flag into a
timestamppb.Timestamp, replacing identical duration-parsing blocks in
api_key.go and preauthkeys.go.
Add apiKeyIDOrPrefix helper to validate the mutually-exclusive --id and
--prefix flags, replacing the duplicated switch block in expireAPIKeyCmd
and deleteAPIKeyCmd.
Centralise the repeated force-flag-check + YesNo-prompt logic into a
single confirmAction(cmd, prompt) helper. Callers still decide what
to return on decline (error, message, or nil).
Replace three inconsistent MarkFlagRequired error-handling styles
(stdlib log.Fatal, zerolog log.Fatal, silently discarded) with a
single mustMarkRequired helper that panics on programmer error.
Also fixes a bug where renameNodeCmd.MarkFlagRequired("new-name")
targeted the wrong command (should be renameUserCmd), making the
--new-name flag effectively never required on "headscale users rename".
Add a helper that checks the --output flag and either serialises as
JSON/YAML or invokes a table-rendering callback. This removes the
repeated format,_ := cmd.Flags().GetString("output") + if-branch from
the five list commands.
