Description of problem: When the host has FIPS enabled both the nova and cinder clients fail. This is reflected in the attached stack trace during a 'server list` operations as an example. The similar issue is encountered during a 'volume list' [0]. Example of the failures: ---------- [root@openshift-jump-1 ~]# openstack server list error:060800A3:digital envelope routines:EVP_DigestInit_ex:disabled for fips [root@openshift-jump-1 ~]# openstack volume list error:060800A3:digital envelope routines:EVP_DigestInit_ex:disabled for fips ---------- Host Details: ---------- [cloud-user@openshift-jump-1 openstack]$ cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.6 (Maipo) [cloud-user@openshift-jump-1 openstack]$ sysctl crypto.fips_enabled crypto.fips_enabled = 1 [cloud-user@openshift-jump-1 openstack]$ cat /proc/sys/crypto/fips_enabled 1 Packages: python2-cinderclient-4.0.1-0.20180809133302.460229c.el7ost.noarch python2-novaclient-11.0.0-0.20180809174649.f1005ce.el7ost.noarch ---------- This appears to be the result in one of the functions under the completion_cache in the {nova,cinder}client/base.py:314 file [1] which uses md5 hashing function and fails as a result of md5 not an approved hashing function under the FIPS [2]. This is reproducible 100% of the time on a FIPS enabled host.
