Rusty Russell	d2b4e09e27	lightningd: re-allow closing negotiation when CLOSINGD_COMPLETE `d822ba1ee` accidentally removed this case, which is important: if the other side didn't get our final matching closing_signed, it will reconnect and try again. We consider the channel no longer "active" and thus ignore it, and get upset when it send the `channel_reestablish` message. We could just consider CLOSINGD_COMPLETE to be active, but then we'd have to wait for the closing transaction to be mined before we'd allow another connection. We can't special case it when the peer reconnects, because there could be (in theory) multiple channels for that peer in CLOSINGD_COMPLETE, and we don't know which one to reestablish. So, we need to catch this when they send the reestablish, and hand that msg to closingd to do negotiation again. We already have code to note that we're in CLOSINGD_COMPLETE and thus ignore any result it gives us. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	7 years ago

lightningd: re-allow closing negotiation when CLOSINGD_COMPLETE

d822ba1ee accidentally removed this case, which is important: if the
other side didn't get our final matching closing_signed, it will
reconnect and try again.  We consider the channel no longer "active"
and thus ignore it, and get upset when it send the
`channel_reestablish` message.

We could just consider CLOSINGD_COMPLETE to be active, but then we'd
have to wait for the closing transaction to be mined before we'd allow
another connection.

We can't special case it when the peer reconnects, because there
could be (in theory) multiple channels for that peer in CLOSINGD_COMPLETE,
and we don't know which one to reestablish.

So, we need to catch this when they send the reestablish, and hand
that msg to closingd to do negotiation again.  We already have code
to note that we're in CLOSINGD_COMPLETE and thus ignore any result
it gives us.
