| Choose Y here to enable Secure RPC using the Kerberos version 5 |
| GSS-API mechanism (RFC 1964). |
| |
| Secure RPC calls with Kerberos require an auxiliary user-space |
| daemon which may be found in the Linux nfs-utils package |
| available from http://linux-nfs.org/. In addition, user-space |
| Kerberos support should be installed. |
| |

| default n |
| help |
| Choose Y here to disable the use of deprecated encryption types |
| with the Kerberos version 5 GSS-API mechanism (RFC 1964). The |
| deprecated encryption types include DES-CBC-MD5, DES-CBC-CRC, |
| and DES-CBC-MD4. These types were deprecated by RFC 6649 because |
| they were found to be insecure. |
| |
| N is the default because many sites have deployed KDCs and |
| keytabs that contain only these deprecated encryption types. |
| Choosing Y prevents the use of known-insecure encryption types |
| but might result in compatibility problems. |

| This option enables a sysctl-based debugging interface |
| that is be used by the 'rpcdebug' utility to turn on or off |
| logging of different aspects of the kernel RPC activity. |
| |
| Disabling this option will make your kernel slightly smaller, |
| but makes troubleshooting NFS issues significantly harder. |

| This option allows the NFS client and server to use RDMA |
| transports (InfiniBand, iWARP, or RoCE). |
| |
| To compile this support as a module, choose M. The module |
| will be called rpcrdma.ko. |
| |
| If unsure, or you know there is no RDMA capability on your |
| hardware platform, say N. |
