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: use release_pages()

2010-10-28T01:03:17+00:00

Replace iterated page_cache_release() with release_pages(), which is
faster and shorter.

Needs release_pages() to be exported to modules.

fuse: use clear_highpage() and KM_USER0 instead of KM_USER1

2010-10-26T23:52:13+00:00

Commit 7909b1c640 ("fuse: don't use atomic kmap") removed KM_USER0 usage
from fuse/dev.c.  Switch KM_USER1 uses to KM_USER0 for clarity.  Also
replace open coded clear_highpage().

use clear_page()/copy_page() in favor of memset()/memcpy() on whole pages

2010-10-26T23:52:13+00:00

After all that's what they are intended for.
