If one or more nodes are misbehaving during recovery, keep track of
failures as ban_credits. If the node with the highest ban_credits exceeds
5 ban credits, then tell recovery daemon to assign banning credits.
This will ban only a single node at a time in case of recovery failure.

On a busy system, TRANS3_COMMIT control can take upto or longer than
3 seconds. On timeout, there are few possible outcomes.
1. The transaction has completed on all nodes and TRANS3_COMMIT control
has returned. In such a case, there is no problem.
2. The transaction has completed on the local node, but TRANS3_COMMIT
control is still active. In such a case, ctdb_transaction_commit()
can return successfully. If this is being called from ctdb, then
ctdb will exit. This will cause ctdb daemon to trigger recovery
since the client exited while transaction is active. This will cause
unnecessary recovery.
3. Database recovery was started and ctdb_transaction_commit() will
retry till the recovery completes the transaction.
Increasing the timeout to 30 seconds will avoid the spurious database
recoveries when TRANS3_COMMIT control takes longer to finish.

It does not make sense to update this statistic for the timeout case,
since this could skew the statistic. To keep it simple, just update
it for the usual case where there is lock contention, since this is
the usual case. So the daemon statistic measures time to test the
lock and the corresponding recovery daemon statistic measures time to
take the lock.
Additionally, the recovery daemon will eventually use this code to
take the lock, and the method of updating the latency statistic will
need to be pushed further out to a configurable handler that depends
on the calling context.

BUG: https://bugzilla.samba.org/show_bug.cgi?id=11707
The checks against database generation are not required since
the global generation is updated as part of updating vnnmap
before the actual database recovery. This change was done in
5aab31a39a.
Checking only against the database generation is incomplete. It can
cause CTDB to abort if the following sequence of events happen.
- CTDB gets REQ_DMASTER packet (gen1)
This packet processing gets deferred to get a record lock
- CTDB goes into recovery, marks RECOVERY_ACTIVE
CTDB recovery helper updates vnnmap (gen2)
- CTDB processes REQ_DMASTER packet (gen1)
The check against database generation (gen1) succeeds.
The check for lmaster is now invalid because VNNMAP has changed.
This will cause CTDB to abort due to protocol error.
Reverting the patch stops processing packets of older generation before
they get into call processing.

For continuity, the ctdb CLI tool code will call out to helper scripts
so that the current status information can still be provided. Those
helper scripts may then reinvoke the ctdb CLI tool to gather
information.
So, redo the tool testing using a "ctdb" stub command. This will

2. Script debugging is launched asynchronously
3. New instance of script is launched, creates temporary file(s)
4. Original hung script makes progress before asynchronous script
debugging kills it, so it removes temporary file(s)
5. New instance of script produces error due to missing files(s)
This is obviously rare.
Use more unique filenames to avoid step (4) removing the file(s)
