xprtrdma: add separate Kconfig options for NFSoRDMA client and server support

2014-03-28T22:02:12Z

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 Signed-off-by: J. Bruce Fields

sunrpc: drop "select NETVM"

2013-04-05T21:03:52Z

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.

SUNRPC: Load GSS kernel module by OID

2013-03-29T19:43:18Z

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.

net/sunrpc: remove depends on CONFIG_EXPERIMENTAL

2013-01-11T19:40:02Z

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs. CC: Trond Myklebust CC: "J. Bruce Fields" CC: "David S.

nfs: enable swap on NFS

2012-08-01T01:42:48Z

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.

SUNRPC/NFS: Add Kbuild dependencies for NFS_DEBUG/RPC_DEBUG

2012-03-20T17:08:26Z

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.

SUNRPC: sunrpc should not explicitly depend on NFS config options

2011-07-15T13:12:23Z

Change explicit references to CONFIG_NFS_V4_1 to implicit ones Get rid of the unnecessary defines in backchannel_rqst.c and bc_svc.c: the Makefile takes care of those dependency. Signed-off-by: Trond Myklebust

SUNRPC: Fix the SUNRPC Kerberos V RPCSEC_GSS module dependencies

2011-04-15T22:28:18Z

Since kernel 2.6.35, the SUNRPC Kerberos support has had an implicit dependency on a number of additional crypto modules. The following patch makes that dependency explicit. Signed-off-by: Trond Myklebust

nfsd4: remove spkm3

2010-10-01T22:09:55Z

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
