It's possible to get a dump of the RPC task queue by writing a value to
/proc/sys/sunrpc/rpc_debug. If you write any value to that file, you get
a dump of the RPC client task list into the log buffer. This is a rather
inconvenient interface however, and makes it hard to get immediate info
about the task queue.Add a new directory hierarchy under debugfs:
sunrpc/
rpc_clnt/
/Within each clientid directory we create a new "tasks" file that will
dump info similar to what shows up in the log buffer, but with a few
small differences -- we avoid printing raw kernel addresses in favor of
symbolic names and the XID is also displayed.Signed-off-by: Jeff Layton

There are two entirely separate modules under xprtrdma/ and there's no
reason that enabling one should automatically enable the other. Add
config options for each one so they can be enabled/disabled separately.Signed-off-by: Jeff Layton

The Kconfig entry for SUNRPC_SWAP selects NETVM. That select statement
was added in commit a564b8f0398636ba30b07c0eaebdef7ff7837249 ("nfs:
enable swap on NFS"). But there's no Kconfig symbol NETVM. It apparently
was only in used in development versions of the swap over nfs
functionality but never entered mainline. Anyhow, it is a nop and can
safely be dropped.Signed-off-by: Paul Bolle

The current GSS mech switch can find and load GSS pseudoflavor
modules by name ("krb5") or pseudoflavor number ("390003"), but
cannot find GSS modules by GSS tuple:[ "1.2.840.113554.1.2.2", GSS_C_QOP_DEFAULT, RPC_GSS_SVC_NONE ]
This is important when dealing with a SECINFO request. A SECINFO
reply contains a list of flavors the server supports for the
requested export, but GSS flavors also have a GSS tuple that maps
to a pseudoflavor (like 390003 for krb5).If the GSS module that supports the OID in the tuple is not loaded,
our client is not able to load that module dynamically to support
that pseudoflavor.Add a way for the GSS mech switch to load GSS pseudoflavor support
by OID before searching for the pseudoflavor that matches the OID
and service.Signed-off-by: Chuck Lever

Implement the new swapfile a_ops for NFS and hook up ->direct_IO. This
will set the NFS socket to SOCK_MEMALLOC and run socket reconnect under
PF_MEMALLOC as well as reset SOCK_MEMALLOC before engaging the protocol
->connect() method.PF_MEMALLOC should allow the allocation of struct socket and related
objects and the early (re)setting of SOCK_MEMALLOC should allow us to
receive the packets required for the TCP connection buildup.[jlayton@redhat.com: Restore PF_MEMALLOC task flags in all cases]

This allows us to turn on/off the dprintk() debugging interfaces for
those distributions that don't ship the 'rpcdebug' utility.
It also allows us to add Kbuild dependencies. Specifically, we already
know that dprintk() in general relies on CONFIG_SYSCTL. Now it turns out
that the NFS dprintks depend on CONFIG_CRC32 after we added support
for the filehandle hash.Reported-by: Paul Gortmaker

Unfortunately, spkm3 never got very far; while interoperability with one
other implementation was demonstrated at some point, problems were found
with the spec that were deemed not worth fixing.The kernel code is useless on its own without nfs-utils patches which
were never merged into nfs-utils, and were only ever available from
citi.umich.edu. They appear not to have been updated since 2005.Therefore it seems safe to assume that this code has no users, and never
will.Signed-off-by: J. Bruce Fields

We just augmented the kernel's RPC service registration code so that
it automatically adjusts to what is supported in user space. Thus we
no longer need the kernel configuration option to enable registering
RPC services with v4 -- it's all done automatically.This patch is part of a series that addresses
