fuse: wakeup pollers on connection release/abort

2011-03-21T12:58:05+00:00

If a fuse dev connection is broken, wake up any
processes that are blocking, in a poll system call,
on one of the files in the now defunct filesystem.

fuse: fix hang of single threaded fuseblk filesystem

2011-02-25T13:44:58+00:00

Single threaded NTFS-3G could get stuck if a delayed RELEASE reply
triggered a DESTROY request via path_put().

Fix this by

 a) making RELEASE requests synchronous, whenever possible, on fuseblk
 filesystems

 b) if not possible (triggered by an asynchronous read/write) then do
 the path_put() in a separate thread with schedule_work().

fuse: fix ioctl ABI

2010-12-07T19:16:56+00:00

In kernel ABI version 7.16 and later FUSE_IOCTL_RETRY reply from a
unrestricted IOCTL request shall return with an array of 'struct
fuse_ioctl_iovec' instead of 'struct iovec'.  This fixes the ABI
ambiguity of 32bit vs. 64bit.

fuse: verify ioctl retries

Verify that the total length of the iovec returned in FUSE_IOCTL_RETRY
doesn't overflow iov_length().

fuse: fix ioctl when server is 32bit

2010-11-30T15:39:27+00:00

If a 32bit CUSE server is run on 64bit this results in EIO being
returned to the caller.

The reason is that FUSE_IOCTL_RETRY reply was defined to use 'struct
iovec', which is different on 32bit and 64bit archs.

Work around this by looking at the size of the reply to determine
which struct was used.  This is only needed if CONFIG_COMPAT is
defined.

A more permanent fix for the interface will be to use the same struct
on both 32bit and 64bit.

fuse: fix attributes after open(O_TRUNC)

2010-11-24T21:50:41+00:00

The attribute cache for a file was not being cleared when a file is opened
with O_TRUNC.

If the filesystem's open operation truncates the file ("atomic_o_trunc"
feature flag is set) then the kernel should invalidate the cached st_mtime
and st_ctime attributes.

Also i_size should be explicitly be set to zero as it is used sometimes
without refreshing the cache.

fuse: fix lock annotations

Sparse doesn't understand lock annotations of the form
__releases(&foo->lock).  Change them to __releases(foo->lock).  Same

fuse: add store request

2010-07-12T12:41:40+00:00

Userspace filesystem can request data to be stored in the inode's
mapping.  This request is synchronous and has no reply.  If the write
to the fuse device returns an error then the store request was not
fully completed (but may have updated some pages).

If the stored data overflows the current file size, then the size is
extended, similarly to a write(2) on the filesystem.

Pages which have been completely stored are marked uptodate.
