fuse: add FUSE_NO_OPEN_SUPPORT flag to INIT

2014-07-22T14:37:43+00:00

Here some additional changes to set a capability flag so that clients can
detect when it's appropriate to return -ENOSYS from open.

This amends the following commit introduced in 3.14:

  7678ac50615d  fuse: support clients that don't implement 'open'

However we can only add the flag to 3.15 and later since there was no
protocol version update in 3.14.

fuse: s_time_gran fix

2014-07-22T14:37:42+00:00

Default s_time_gran is 1, don't overwrite that if userspace didn't
explicitly specify one.

fuse: handle large user and group ID

2014-07-07T13:28:51+00:00

If the number in "user_id=N" or "group_id=N" mount options was larger than
INT_MAX then fuse returned EINVAL.

Fix this to handle all valid uid/gid values.

fuse: inode: drop cast

2014-07-07T13:28:51+00:00

This patch removes the cast on data of type void * as it is not needed.
The following Coccinelle semantic patch was used for making the change:

@r@
expression x;
void* e;
type T;
identifier f;
@@

(
  *((T *)e)
|
  ((T *)x)[...]
|
  ((T *)x)->f
|
- (T *)
  e
)

fuse: clear MS_I_VERSION

2014-04-28T12:19:25+00:00

Fuse doesn't support i_version (yet).

fuse: trust kernel i_ctime only

2014-04-28T12:19:24+00:00

Let the kernel maintain i_ctime locally: update i_ctime explicitly on
truncate, fallocate, open(O_TRUNC), setxattr, removexattr, link, rename,
unlink.

The inode flag I_DIRTY_SYNC serves as indication that local i_ctime should
be flushed to the server eventually.  The patch sets the flag and updates
i_ctime in course of operations listed above.

fuse: fuse: add time_gran to INIT_OUT

2014-04-28T12:19:23+00:00

Allow userspace fs to specify time granularity.

This is needed because with writeback_cache mode the kernel is responsible
for generating mtime and ctime, but if the underlying filesystem doesn't
support nanosecond granularity then the cache will contain a different
value from the one stored on the filesystem resulting in a change of times
after a cache flush.

Make the default granularity 1s.

fuse: add .write_inode

2014-04-28T12:19:23+00:00

...and flush mtime from this.  This allows us to use the kernel
infrastructure for writing out dirty metadata (mtime at this point, but
ctime in the next patches and also maybe atime).

fuse: do not use uninitialized i_mode

2014-04-28T12:19:21+00:00

When inode is in I_NEW state, inode->i_mode is not initialized yet. Do not
use it before fuse_init_inode() is called.

Pull ext4 updates from Ted Ts'o:
 "Major changes for 3.14 include support for the newly added ZERO_RANGE
  and COLLAPSE_RANGE fallocate operations, and scalability improvements
  in the jbd2 layer and in xattr handling when the extended attributes
  spill over into an external block.

  Other than that, the usual clean ups and minor bug fixes"
