In get_rule_avail(), even p->second is 0, it's possible to be used as divisor and quotient is infinity, then is converted to an integer which is negative value. So we should check p->second value before calculation. It fixes BUG ceph#13840. Signed-off-by: Chengyuan Li <chengyli@ebay.com> (cherry picked from commit 18713e6)

@liewegas does this backport look good to merge ? It passed a run of the hammer rados suite ( see http://tracker.ceph.com/issues/13356#note-34 for details ) and the upgrade/hammer suite ( see http://tracker.ceph.com/issues/13356#note-37 for details ). |
