* xprtrdma: add separate Kconfig options for NFSoRDMA client and server supportJeff Layton2014-03-281-13/+26
| | | | | | | | | 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 <jlayton@redhat.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

| * SUNRPC: Load GSS kernel module by OIDChuck Lever2013-03-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | sunrpc: drop "select NETVM"Paul Bolle2013-04-051-1/+0
|/ | | | | | | | | | | | 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 <pebolle@tiscali.nl> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* nfs: enable swap on NFSMel Gorman2012-07-311-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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_DEBUGTrond Myklebust2012-03-201-0/+13
| | | | | | | | | | | | 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.

* nfsd4: remove spkm3J. Bruce Fields2010-10-011-19/+0
| | | | | | | | | | | | | | | 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 <bfields@redhat.com>
