[PATCH v2 0/8] Support btime and other NFSv4 specific attributes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

NFSv4 has support for a number of extra attributes that are of interest
to Samba when it is used to re-export a filesystem to Windows clients.
Aside from the btime, which is of interest in statx(), Windows clients
have an interest in determining the status of the 'hidden', and 'system'
flags.
Backup programs want to read the 'archive' flags and the 'time backup'
attribute.
Finally, the 'offline' flag can tell whether or not a file needs to be
staged by an HSM system before it can be read or written to.

The patch series also adds an ioctl() to allow userspace retrieval and
setting of these attributes where appropriate. It also adds an ioctl()
to allow retrieval of the raw NFSv4 ACCESS information, to allow more
fine grained determination of the user's access rights to a file or
directory. All of this information is of use for Samba.


- v2: Rebase on top of Anna's linux-next

Anne Marie Merritt (3):
  nfs: Add timecreate to nfs inode
  nfs: Add 'archive', 'hidden' and 'system' fields to nfs inode
  nfs: Add 'time backup' to nfs inode

Richard Sharpe (1):
  NFS: Support statx_get and statx_set ioctls

Trond Myklebust (4):
  NFS: Expand the type of nfs_fattr->valid
  NFS: Return the file btime in the statx results when appropriate
  NFSv4: Support the offline bit
  NFSv4: Add an ioctl to allow retrieval of the NFS raw ACCESS mask
