nfsd: add get_uint for u32's

2012-11-17T21:16:12Z

commit a007c4c3e943ecc054a806c259d95420a188754b upstream. I don't think there's a practical difference for the range of values these interfaces should see, but it would be safer to be unambiguous. Signed-off-by: J. Bruce Fields Cc: Sasha Levin Signed-off-by: Greg Kroah-Hartman

SUNRPC: Fix a UDP transport regression

2012-10-28T17:14:13Z

commit f39c1bfb5a03e2d255451bff05be0d7255298fa4 and commit 84e28a307e376f271505af65a7b7e212dd6f61f4 upstream. Commit 43cedbf0e8dfb9c5610eb7985d5f21263e313802 (SUNRPC: Ensure that we grab the XPRT_LOCK before calling xprt_alloc_slot) is causing hangs in the case of NFS over UDP mounts. Since neither the UDP or the RDMA transport mechanism use dynamic slot allocation, we can skip grabbing the socket lock for those transports. Add a new rpc_xprt_op to allow switching between the TCP and UDP/RDMA case. Note that the NFSv4.1 back channel assigns the slot directly through rpc_run_bc_task, so we can ignore that case.

SUNRPC: new svc_bind() routine introduced

2012-07-16T16:04:39Z

upstream commit 9793f7c88937e7ac07305ab1af1a519225836823. This new routine is responsible for service registration in a specified network context. The idea is to separate service creation from per-net operations. Note also: since registering service with svc_bind() can fail, the service will be destroyed and during destruction it will try to unregister itself from rpcbind. In this case unregistration has to be skipped. Signed-off-by: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields Signed-off-by: Greg Kroah-Hartman

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: Add API to acquire source address

2012-03-02T20:36:53Z

NFSv4.0 clients must send endpoint information for their callback service to NFSv4.0 servers during their first contact with a server. Traditionally on Linux, user space provides the callback endpoint IP address via the "clientaddr=" mount option. During an NFSv4 migration event, it is possible that an FSID may be migrated to a destination server that is accessible via a different source IP address than the source server was. The client must update callback endpoint information on the destination server so that it can maintain leases and allow delegation. Without a new "clientaddr=" option from user space, however, the kernel itself must construct an appropriate IP address for the callback update. Provide an API in the RPC client for upper layer RPC consumers to acquire a source address for a remote. The mechanism used by the mount.nfs command is copied: set up a connected UDP socket to the designated remote, then scrape the source address off the socket. We are careful to select the correct network namespace when setting up the temporary UDP socket. Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust

SUNRPC: Move clnt->cl_server into struct rpc_xprt

2012-03-02T20:36:41Z

When the cl_xprt field is updated, the cl_server field will also have to change. Since the contents of cl_server follow the remote endpoint of cl_xprt, just move that field to the rpc_xprt.
