Read the HEADSCALE_INTEGRATION_*_IMAGE knobs through one envknob helper and
assert required tooling is present instead of installing it at runtime (the
nix VM is offline). dsic waits for both the derper cert and key before starting
derper, so the container can't die between the two uploads. The nested-docker
VM is slower than a host daemon, so every integration timeout (convergence,
docker exec, peer sync, pool wait) now flows through one
dockertestutil.ScaleTimeout honouring HEADSCALE_INTEGRATION_TIMEOUT_SCALE.
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
Categorised timeouts in integrationutil/timeouts.go remove the drift
opportunity between same-purpose budgets repeated across the suite.
The auth, cli, dns, derp, ssh, and tags tests are swept; acl, route,
and general tests follow in later commits alongside their other
ergonomic fixes.
Add ScaledTimeout to scale EventuallyWithT timeouts by 2x on CI,
consistent with the existing PeerSyncTimeout (60s/120s) and
dockertestMaxWait (300s/600s) conventions.
Add assertCurlSuccessWithCollect and assertCurlFailWithCollect helpers
following the existing *WithCollect naming convention.
assertCurlFailWithCollect uses CurlFailFast internally for aggressive
timeouts, avoiding wasted retries when expecting blocked connections.
Apply these to the three flakiest ACL tests:
- TestACLTagPropagation: swap NetMap and curl verification order so
the fast NetMap check (confirms MapResponse arrived) runs before
the slower curl check. Use curl helpers and scaled timeouts.
- TestACLTagPropagationPortSpecific: use curl helpers and scaled
timeouts.
- TestACLHostsInNetMapTable: scale the 10s EventuallyWithT timeout.
Updates #3125
Make embedded DERP server and TLS the default configuration for all
integration tests, replacing the per-test opt-in model that led to
inconsistent and flaky test behavior.
Infrastructure changes:
- DefaultConfigEnv() includes embedded DERP server settings
- New() auto-generates a proper CA + server TLS certificate pair
- CA cert is installed into container trust stores and returned by
GetCert() so clients and internal tools (curl) trust the server
- CreateCertificate() now returns (caCert, cert, key) instead of
discarding the CA certificate
- Add WithPublicDERP() and WithoutTLS() opt-out options
- Remove WithTLS(), WithEmbeddedDERPServerOnly(), and WithDERPAsIP()
since all their behavior is now the default or unnecessary
Test cleanup:
- Remove all redundant WithTLS/WithEmbeddedDERPServerOnly/WithDERPAsIP
calls from test files
- Give every test a unique WithTestName by parameterizing aclScenario,
sshScenario, and derpServerScenario helpers
- Add WithTestName to tests that were missing it
- Document all non-standard options with inline comments explaining
why each is needed
Updates #3139
Errors should not start capitalised and they should not contain the word error
or state that they "failed" as we already know it is an error

This commit injects the per-test-generated tls certs into the tailscale
container and makes sure all can ping all. It does not test any of the
DERP isolation yet.
