.New encryption types for the RPCSEC GSS Kerberos V5
The RPCSEC GSS Kerberos V5 mechanism now supports encryption types defined in RFC 6803 (Camellia Encryption for Kerberos 5) and RFC 8009 (AES Encryption with HMAC-SHA2 for Kerberos 5).
The following encryption types have been added:
* `camellia128-cts-cmac`
* `camellia256-cts-cmac`
* `aes128-cts-hmac-sha256-128`
* `aes256-cts-hmac-sha384-192`
This allows NFS clients and NFS servers to use stronger encryption types when negotiating GSS contexts.

Have verified NFS with Kerberos now can work on camellia128-cts-cmac/camellia256-cts-cmac E.g. https://beaker.engineering.redhat.com/jobs/7810883 https://beaker.engineering.redhat.com/jobs/7810999 -------------------- [21:34:46 root@ ~~]# cat /proc/fs/nfsd/supported_krb5_enctypes 20,19,26,25,18,17 {Info} 20 - the NFS server supports encryption aes256-cts-hmac-sha384-192 {Info} 19 - the NFS server supports encryption aes128-cts-hmac-sha256-128 {Info} 26 - the NFS server supports encryption camellia256-cts-cmac {Info} 25 - the NFS server supports encryption camellia128-cts-cmac {Info} 18 - the NFS server supports encryption aes256-cts-hmac-sha1-96 {Info} 17 - the NFS server supports encryption aes128-cts-hmac-sha1-96 [21:34:47 root@ ~~]# klist -e -k Keytab name: FILE:/etc/krb5.keytab KVNO Principal ---- -------------------------------------------------------------------------- 2 host/kvm-04-guest17.lab.eng.rdu2.redhat.com (camellia256-cts-cmac) 2 nfs/kvm-04-guest17.lab.eng.rdu2.redhat.com (camellia256-cts-cmac) 2 cifs/kvm-04-guest17.lab.eng.rdu2.redhat.com (camellia256-cts-cmac) [21:34:47 root@ ~~]# mount -t nfs -o sec=krb5 kvm-04-guest17.lab.eng.rdu2.redhat.com:/exportDir-krb5-crypto /mnt/nfsmp-krb5-crypto [21:34:47 root@ ~~]# nfsstat -m /mnt/nfsmp-krb5-crypto from kvm-04-guest17.lab.eng.rdu2.redhat.com:/exportDir-krb5-crypto Flags: rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp6,timeo=600,retrans=2,sec=krb5,clientaddr=2620:52:0:800:216:3eff:fe34:33c9,local_lock=none,addr=2620:52:0:800:216:3eff:fe34:33c9 [21:34:48 root@ ~~]# umount /mnt/nfsmp-krb5-crypto But camellia128/camellia256 with fips enabled get failed.

Maybe that's as > expected but I need to get some docs later. This should be as expected as https://pagure.io/freeipa/issue/8111 says, i.e., the camellia is not added into KRB5 encsalttypes in FIPS mode. I'm verifying this bug for now.
