default y
select SUNRPC_GSS
select CRYPTO_KRB5
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_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_DEBUG_TRACE
bool "RPC: Send dfprintk() output to the trace buffer"
depends on SUNRPC_DEBUG && TRACING
default n
help
dprintk() output can be voluminous, which can overwhelm the
kernel's logging facility as it must be sent to the console.
This option causes dprintk() output to go to the trace buffer
instead of the kernel log.
This will cause warnings about trace_printk() being used to be
logged at boot time, so say N unless you are debugging a problem
with sunrpc-based clients or services.
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.
