In commit 1ee7053180, the
ctdb_rec_buffer_traverse always passes NULL for header. So explicitly
extract header from the data.

Logging that node has lost election is less useful than knowing which

The ipalloc code doesn't need a CTDB context so neither should the

At the moment IP is short-circuited when there are no available IP
addresses. However, if some IP addresses are already allocated then
"no available IP addresses" means that all the addresses should
(probably) be released. The current short-circuit means that no
already hosted IP addresses will be released.
The short-circuit exists to avoid lots of messages saying that all IP
addresses can not be assigned at startup time. So, add a check to
ipalloc_can_host_ips() so that it succeeds if IP addresses are already
allocated to nodes.

Factor out new function ctdb_fetch_remote_public_ips() to fetch known

This also drops the hack where the array from a

It is only run during a takeover run and only logs errors. It doesn't
actually do anything to fix potential errors. The takeover run should
fix any inconsistencies anyway.
Instead, leave a comment in the recovery daemon's monitoring loop to
add proper remote IP verification later.

This pointer is for an array that is always allocated. The check is
meant to skip a node that has no IP addresses. However, when there
are no IP addresses the loop below will not do anything anyway.
Add this as a check at the beginning of the function instead.

If there is per-node data then each chunk is read in a separate call
and is cherry-picked out into known_public_ips[] for each node. This
is confusing.
Instead, a single call now reads all data for multiple nodes and
returns complete arrays of known and available IP addresses.
