This does not work, BTW, since the other peer gets upset! I will alter the spec to change the numbers not to clash... Done. Spec updated. |

Drafted and removed from milestone since it cannot be merged as is, due to failure scenarios that weren't considered. |

Importantly, this version no longer assumes features 34/35 are unused. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
The latest draft has a feature bit here. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
It now uses raw bitfields instead of a subtype, and only allows a single option for any upgrade. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
…FEATURES. We switched channel_types from optional to compulsory bits in cb22015. The result is infinite reconnects against older nodes; we reject what they send, and they reject what we send. The simplest fix is to neither send nor receive the (optional!) tlvs unless we both advertize option_quiesce, which we now do. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-EXPERIMENTAL: channel_upgrade draft upgraded: cannot upgrade channels until peers also upgrade.

We switched channel_types from optional to compulsory bits in
cb22015.
The result is infinite reconnects against older nodes.
We needed to upgrade the spec anyway, so I did that, and handle backwards compat.
