Push the file layout driver into a subdirectory

2014-05-30T00:21:56+00:00

The object and block layouts already exist in their own subdirectories. This patch completes the set! Note that as a layout denotes nfs4 already, I stripped that prefix out of the file names. Signed-off-by: Tom Haynes Acked-by: Jeff Layton Signed-off-by: Trond Myklebust

nfs: fix dead code of ipv6_addr_scope

2014-01-05T20:38:21+00:00

The correct way to check on IPV6_ADDR_SCOPE_LINKLOCAL is to check with the ipv6_addr_src_scope function. Currently this can't be work, because ipv6_addr_scope returns a int with a mask of IPV6_ADDR_SCOPE_MASK (0x00f0U) and IPV6_ADDR_SCOPE_LINKLOCAL is 0x02. So the condition is always false.

NFSv4.1: Ensure memory ordering between nfs4_ds_connect and nfs4_fl_prepare_ds

2013-09-29T19:58:35+00:00

We need to ensure that the initialisation of the data server nfs_client structure in nfs4_ds_connect is correctly ordered w.r.t. the read of ds->ds_clp in nfs4_fl_prepare_ds. Signed-off-by: Trond Myklebust

NFSv4.1: nfs4_fl_prepare_ds - fix bugs when the connect attempt fails

2013-09-29T19:56:35+00:00

- Fix an Oops when nfs4_ds_connect() returns an error. - Always check the device status after waiting for a connect to complete. Reported-by: Andy Adamson Reported-by: Jeff Layton Signed-off-by: Trond Myklebust Cc: # v3.10+

NFSv4.1 Fix gdia_maxcount calculation to fit in ca_maxresponsesize

2013-06-28T19:34:43+00:00

The GETDEVICEINFO gdia_maxcount represents all of the data being returned within the GETDEVICEINFO4resok structure and includes the XDR overhead. The CREATE_SESSION ca_maxresponsesize is the maximum reply and includes the RPC headers (including security flavor credentials and verifiers). Split out the struct pnfs_device field maxcount which is the gdia_maxcount from the pglen field which is the reply (the total) buffer length.

NFSv4.1: Use layout credentials for get_deviceinfo calls

2013-06-06T20:24:37+00:00

This is not strictly needed, since get_deviceinfo is not allowed to return NFS4ERR_ACCESS or NFS4ERR_WRONG_CRED, but lets do it anyway for consistency with other pNFS operations. Signed-off-by: Trond Myklebust

NFS4.1 Fix data server connection race

2013-05-08T21:19:32+00:00

Unlike meta data server mounts which support multiple mount points to the same server via struct nfs_server, data servers support a single connection. Concurrent calls to setup the data server connection can race where the first call allocates the nfs_client struct, and before the cache struct nfs_client pointer can be set, a second call also tries to setup the connection, finds the already allocated nfs_client, bumps the reference count, re-initializes the session,etc. This results in a hanging data server session after umount.

sunrpc: move address copy/cmp/convert routines and prototypes from clnt.h to addr.h

2013-02-05T14:41:14+00:00

These routines are used by server and client code, so having them in a separate header would be best. Signed-off-by: Jeff Layton Acked-by: Trond Myklebust Signed-off-by: J. Bruce Fields

NFSv4.1: Cleanup move session slot management to fs/nfs/nfs4session.c

NFSv4.1 session management is getting complex enough to deserve a separate file. Signed-off-by: Trond Myklebust
