Upstream fix: https://github.com/ceph/ceph-ansible/pull/5964

RHOSP13(queens): 'deploy gateway settings' was still in tasks/prerequisites.yml (moved later to tasks/common.yml), but has the same error (600 mode isn't specified for the iscsi-gateway.cfg file).
Comment 12 Sage McTaggart 2020-11-20 02:42:25 UTC 
Statement:

Red Hat OpenStack Platform 13 ships the flawed code, however RHOSP does not deploy ceph-iscsi-gw role in any supported scenario.  For this reason, a ceph-ansible update will not be provided at this time.

Red Hat Ceph Storage 3 and 4 create /etc/ceph/iscsi-gateway.conf with the insecure permissions.
Comment 14 errata-xmlrpc 2021-01-12 14:56:32 UTC
