The interstitial was the body of /oidc/callback, the URL carrying the
single-use code, so any reload re-entered the spent exchange. Redirect to
GET /register/confirm/{auth_id}, also missing from the route table.
Go 1.27 allows setting promoted fields of embedded structs directly in
composite literals, so gorm.Model wrappers go away. Plus strings.Cut,
errors.AsType, reflect.TypeAssert and one gofumpt nit.
/key handed out the Noise public key for any v>=39, a floor unrelated
to the handshake's capver.MinSupportedCapabilityVersion. Reject below
the supported floor, matching /ts2021, and drop the stale constant.
Fixes#3380
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
Add httpUserError() alongside httpError() for browser-facing error
paths. It renders a styled HTML page using the AuthError template
instead of returning plain text. Technical error details stay in
server logs; the HTML page shows actionable messages derived from
the HTTP status code:
401/403 → "You are not authorized. Please contact your administrator."
410 → "Your session has expired. Please try again."
400-499 → "The request could not be processed. Please try again."
500+ → "Something went wrong. Please try again later."
Convert all httpError calls in oidc.go (OIDC callback, SSH check,
registration confirm) to httpUserError. Machine-facing endpoints
(noise, verify, key, health, debug) are unchanged.
