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 fs/nfs/dir.c | 71 ++--- fs/nfs/getroot.c | 3 +- fs/nfs/inode.c | 147 +++++++++- fs/nfs/internal.h | 10 + fs/nfs/nfs3proc.c | 1 + fs/nfs/nfs4_fs.h | 31 +++ fs/nfs/nfs4file.c | 550 ++++++++++++++++++++++++++++++++++++++ fs/nfs/nfs4proc.c | 175 +++++++++++- fs/nfs/nfs4trace.h | 8 +- fs/nfs/nfs4xdr.c | 240 +++++++++++++++-- fs/nfs/nfstrace.c | 5 + fs/nfs/nfstrace.h | 9 +- fs/nfs/proc.c | 1 + include/linux/nfs4.h | 1 + include/linux/nfs_fs.h | 15 ++ include/linux/nfs_fs_sb.h | 2 +- include/linux/nfs_xdr.h | 80 ++++-- include/uapi/linux/nfs.h | 101 +++++++ 18 files changed, 1355 insertions(+), 95 deletions(-) -- 2.33.1
