NFS: Remove the "NFS_CAP_CHANGE_ATTR" capability

2015-07-22T21:15:54+00:00

Setting the change attribute has been mandatory for all NFS versions, since commit 3a1556e8662c ("NFSv2/v3: Simulate the change attribute"). We should therefore not have anything be conditional on it being set/unset. Signed-off-by: Trond Myklebust

nfs: Fix showing truncated fsid/dev in, /proc/net/nfsfs/volumes

2015-06-16T15:17:37+00:00

A truncated fsid showing from /proc/fs/nfsfs/volumes as, NV SERVER PORT DEV FSID FSC v4 c0a80881 801 0:43 34931f044c2a439b no It should be as, NV SERVER PORT DEV FSID FSC v4 c0a80881 801 0:43 34931f044c2a439b:954c5d830fa4be8c no The max buffer length for storing "%llx:%llx" format should be 16 + 1 + 16 + 1 = 34 (16 for %llx, 1 for ':', 1 for '\0'). Also, for storing "%u:%u" of MAJOR() and MINOR() should be 8 + 1 + 3 + 1 = 13 (8 for 2^24, 1 for ':', 3 for 2^8, 1 for '\0'). v2, add comments for dev/fsid buffer and use sizeof in snprintf.

NFS: Remove CONFIG_NFS_V4 checks from nfs_idmap.h

2015-04-23T19:16:13+00:00

The idmapper is completely internal to the NFS v4 module, so this macro will always evaluate to true. This patch also removes unnecessary includes of this file from the generic NFS client. Signed-off-by: Anna Schumaker Signed-off-by: Trond Myklebust

NFSv4: Fix a race in NFSv4.1 server trunking discovery

2015-03-04T01:42:23+00:00

We do not want to allow a race with another NFS mount to cause nfs41_walk_client_list() to establish a lease on our nfs_client before we're done checking for trunking. Signed-off-by: Trond Myklebust

nfs: fix duplicate proc entries

Commit 65b38851a174 ("NFS: Fix /proc/fs/nfsfs/servers and /proc/fs/nfsfs/volumes") updated the following function: static int nfs_volume_list_open(struct inode *inode, struct file *file) it used &nfs_server_list_ops instead of &nfs_volume_list_ops which means cat /proc/fs/nfsfs/volumes = /proc/fs/nfsfs/servers Signed-off-by: Fabian Frederick Fixes: 65b38851a174 (NFS: Fix /proc/fs/nfsfs/servers and...)
