This is in line with the warnings draft, where all-zeroes in a channel_id is no longer special (i.e. it will be ignored). But gossipd would send these if it got upset with us, so it's best practice to ignore them for now anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-Added: Protocol: we treat error messages from peer which refer to "all channels" as warnings, not errors.
