ctdb_mutex_ceph_rados_helper: revert strtoull_err() usage

2019-03-01T18:34:18+00:00

Compilation currently fails, as ctdb_mutex_ceph_rados_helper doesn't
include or link against the samba-util library. Revert back to the
previous strtoull() behaviour, which works fine.

ctdb-utils: Use wrapper for string to integer conversion

2019-03-01T00:32:11+00:00

In order to detect an value overflow error during
the string to integer conversion with strtoul/strtoull,
the errno variable must be set to zero before the execution and
checked after the conversion is performed. This is achieved by
using the wrapper function strtoul_err and strtoull_err.

ctdb_mutex_ceph_rados_helper: fix deadlock via lock renewals

2018-08-09T11:29:15+00:00

RADOS locks without expiry persist indefinitely. This results in CTDB
deadlock during failover if the recovery master dies unexpectedly, as
subsequently elected recovery master nodes can't obtain the recovery
lock.
Avoid deadlock by using a lock expiration time (10s by default), and
renewing it periodically.
