The receiving node: ...

below the agreed upon transaction `feerate`

We consolidate to the latest/singular RFC patch for dual-funding, so
there's just a single patchfile for the change. Plus we move back to the
opener setting the desired feerate, the accepter merely declines to
participate if they disagree with the set rate.
Just a security measure to avoid alternative use-cases of the hsmd
running into the issue that they need to send a `WIRE_HSMD_INIT`
message as first message. If that is not done, the `secretstuff` won't
get initialized and we'd be producing signatures from uninitialized
memory, which are completely useless.
Changelog-None: Internal change only
Looks like #4394 treated a symptom but not the root cause. We were
actually sending the message framed with the WIRE_CUSTOMMSG_OUT and
the length prefix over the encrypted connection to the peer. It just
happened to be a valid custommsg...
This fixes the issue, and this time I made sure we actually send the
raw message over the wire. However for backward compatibility we
needed to imitate the faulty behavior which is 90% of this patch :-)
Changelog-Fixed: plugin: `dev-sendcustommsg` included the type and length prefix when sending a message.
We were getting a memleak error that the open_attempt isnt' being
cleaned up in test_rbf_reconnect_tx_construct. I had some trouble
reproducing it, so I removed the reliance on using `tmpctx` to clean it
up and was more surgical about cleaning it up inline.
Changelog-Added: JSON-RPC: `listpeers` now includes 'last_feerate', 'next_feerate', 'initial_feerate' and 'next_fee_step' for channels in state DUALOPEND_AWAITING_LOCKIN
fixup! listpeers: include feerate info for RBF-candidate channels
If we're doing an RBF, it's possible that the peer will send us a
funding_locked, shutdown, or tx_signatures message. (We get tx_sigs out
of order on a reconnect)
This lets us gracefully handle a shutdown or funding_locked
sent at any time (after first funding tx) as well.
We move over to the new "warning" paradigm, instead of using
an "rbf_fail" message.
Every failure is either a warning or an error; on warnings we
hang up and reconnect later, effectively resetting the state.
We're *mostly* set up for both sides doing RBF, except that it reverses
the callback flow (using the plugin vs RPC calls) and we're not
currently smart enough to flip between them gracefully
Users have no idea what they would pay for unilateral closes.
At least this gives them a clue!

only needed for moving the subd->channel from an uncommitted_channel to
a channel; we removed uncommitted_channel from dual_open so it's no
longer necessary
