default y
select SUNRPC_GSS
help
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.
If unsure, say Y.
config SUNRPC_DISABLE_INSECURE_ENCTYPES
bool "Secure RPC: Disable insecure Kerberos encryption types"
depends on RPCSEC_GSS_KRB5
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.
config SUNRPC_DEBUG
bool "RPC: Enable dprintk debugging"
depends on SUNRPC && SYSCTL
select DEBUG_FS
help
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.
If unsure, say Y.
config SUNRPC_XPRT_RDMA
tristate "RPC-over-RDMA transport"
depends on SUNRPC && INFINIBAND && INFINIBAND_ADDR_TRANS
default SUNRPC && INFINIBAND
select SG_POOL
help
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.
