WithSelfNode and buildTailPeers merge each node's policy CapMap
into the tailcfg.Node.CapMap they emit. State.NodeCapMap and
State.NodeCapMaps wrap the policy manager: NodeCapMap returns a
defensive clone per call; NodeCapMaps snapshots the full per-node
map once for batched callers, amortising pm.mu acquisition across
a peer build.
generateDNSConfig grew a per-node CapMap argument so it can apply
nodeAttr-driven DNS overlays. The nextdns DoH rewrite hardens against
policy-controlled inputs:
- nextDNSDoHHost anchors the prefix match instead of substring,
so a hostile resolver URL cannot smuggle a nextdns hostname in
a path or query.
- nextDNSProfileFromCapMap accepts only profile names matching
[A-Za-z0-9._-]{1,64} and picks the lexicographically first when
multiple are granted -- deterministic, no shell metacharacters
or URL fragments through.
- addNextDNSMetadata composes the rewritten URL via url.Parse +
url.Values rather than fmt.Sprintf, so existing query strings
on the resolver URL survive and metadata cannot inject a new
component.
WithTaildropEnabled in servertest controls cfg.Taildrop.Enabled per
test so cap/file-sharing emission can be toggled in tests that need
to verify the off path.
