Add a new protocol option, protocol.onion-msg-relay-all, that controls
whether incoming onion messages are required to come from peers with a
fully open channel. The default is false, which preserves the existing
behavior: the channel-presence gate drops messages from peers with no
channel before the rate limiters are consulted, so a new no-cost
identity cannot burn any per-peer byte budget and saturate the global
bucket. Setting the flag to true skips the gate so that onion messages
from any peer are admitted into the per-peer + global IngressLimiter
pipeline.
The flag is plumbed through ProtocolOptions in both the default and
integration build variants of lncfg/protocol*.go, threaded into the
peer subsystem as peer.Config.OnionRelayAll, and wired by the server
from s.cfg.ProtocolOptions.OnionMsgRelayAll alongside the existing
OnionLimiter field. allowOnionMessage gains a relayAll bool parameter;
the gate check becomes "if \!relayAll && \!hasChannel { drop }" so the
semantics of hasChannel stay pure — it still means "this peer has a
channel" — and the policy toggle lives entirely in the caller's
configuration rather than being spread across gate-state and flag
state.
sample-lnd.conf gains a commented-out entry for the new option with
the default value and an operator-facing note that enabling it trades
the Sybil-resistance property of the gate for reachability to peers
with whom we have no channel.
A new TestAllowOnionMessageRelayAll unit test exercises the four
(hasChannel, relayAll) combinations at the helper level, including
the key new behavior — a peer with hasChannel=false being rejected
under relayAll=false and admitted into the limiter under
relayAll=true — and the nil-limiter path under relayAll=true, which
must still accept. The existing allowOnionMessage tests were
extended with the new parameter set to false so they continue to
assert the gate semantics unchanged.
