Cornelia Huck 8a82472f86 driver core: Introduce device_move(): move a device to a new parent.
Provide a function device_move() to move a device to a new parent device. Add
auxilliary functions kobject_move() and sysfs_move_dir().
kobject_move() generates a new uevent of type KOBJ_MOVE, containing the
previous path (DEVPATH_OLD) in addition to the usual values. For this, a new
interface kobject_uevent_env() is created that allows to add further
environmental data to the uevent at the kobject layer.

Thomas Maier 035ed7a494 sysfs: sysfs_write_file() writes zero terminated data
since most of the files in sysfs are text files,
it would be nice, if the "store" function called
during sysfs_write_file() gets a zero terminated
string / data.
The current implementation seems not to ensure this.
(But only if it is the first time the zeroed buffer
page is allocated.)

So the buffer can be scanned by sscanf() easily,
for example.

This patch simply sets a \0 char behind the
data in buffer->page.

Mike Christie ad2d722570 [PATCH] block: kill length alignment test in bio_map_user()
The target mode support is mapping in bios using bio_map_user. The
current targets do not need their len to be aligned with a queue limit
so this check is causing some problems. Note: pointers passed into the
kernel are properly aligned by usersapace tgt code so the uaddr check
in bio_map_user is ok.

The major user, blk_bio_map_user checks for the len before mapping
so it is not affected by this patch.

And the semi-newly added user blk_rq_map_user_iov has been failing
out when the len is not aligned properly so maybe people have been
good and not sending misaligned lens or that path is not used very
often and this change will not be very dangerous. st and sg do not
check the length and we have not seen any problem reports from those
wider used paths so this patch should be fairly safe - for mm
and wider testing at least.

Miklos Szeredi 2d51013ed2 [PATCH] fuse: fix Oops in lookup
Fix bug in certain error paths of lookup routines.  The request object was
reused for sending FORGET, which is illegal.  This bug could cause an Oops
in 2.6.18.  In earlier versions it might silently corrupt memory, but this
is very unlikely.

These error paths are never triggered by libfuse, so this wasn't noticed
even with the 2.6.18 kernel, only with a filesystem using the raw kernel
interface.

Thanks to Russ Cox for the bug report and test filesystem.

Hugh Dickins 68589bc353 [PATCH] hugetlb: prepare_hugepage_range check offset too
(David:)

If hugetlbfs_file_mmap() returns a failure to do_mmap_pgoff() - for example,
because the given file offset is not hugepage aligned - then do_mmap_pgoff
will go to the unmap_and_free_vma backout path.

But at this stage the vma hasn't been marked as hugepage, and the backout path
will call unmap_region() on it.  That will eventually call down to the
non-hugepage version of unmap_page_range().  On ppc64, at least, that will
cause serious problems if there are any existing hugepage pagetable entries in
the vicinity - for example if there are any other hugepage mappings under the
same PUD.  unmap_page_range() will trigger a bad_pud() on the hugepage pud
entries.  I suspect this will also cause bad problems on ia64, though I don't
have a machine to test it on.

(Hugh:)

prepare_hugepage_range() should check file offset alignment when it checks
virtual address and length, to stop MAP_FIXED with a bad huge offset from
unmapping before it fails further down.  PowerPC should apply the same
prepare_hugepage_range alignment checks as ia64 and all the others do.

Then none of the alignment checks in hugetlbfs_file_mmap are required (nor
is the check for too small a mapping); but even so, move up setting of
VM_HUGETLB and add a comment to warn of what David Gibson discovered - if
hugetlbfs_file_mmap fails before setting it, do_mmap_pgoff's unmap_region
when unwinding from error will go the non-huge way, which may cause bad
behaviour on architectures (powerpc and ia64) which segregate their huge
mappings into a separate region of the address space.

David Chinner 4c60658e0f [XFS] Prevent a deadlock when xfslogd unpins inodes.
The previous fixes for the use after free in xfs_iunpin left a nasty log
deadlock when xfslogd unpinned the inode and dropped the last reference to
the inode. the ->clear_inode() method can issue transactions, and if the
log was full, the transaction could push on the log and get stuck trying
to push the inode it was currently unpinning.

To fix this, we provide xfs_iunpin a guarantee that it will always have a
valid xfs_inode <-> linux inode link or a particular flag will be set on
the inode. We then use log forces during lookup to ensure transactions are
completed before we recycle the inode. This ensures that xfs_iunpin will
never use the linux inode after it is being freed, and any lookup on an
inode on the reclaim list will wait until it is safe to attach a new linux
inode to the xfs inode.

J. Bruce Fields 088406bcf6 [PATCH] nfsd: fix spurious error return from nfsd_create in async case
Commit 6264d69d7d modified the nfsd_create()
error handling in such a way that nfsd_create will usually return
nfserr_perm even when succesful, if the export has the async export option.

This introduced a regression that could cause mkdir() to always return a
permissions error, even though the directory in question was actually
succesfully created.

J. Bruce Fields 81ac95c556 [PATCH] nfsd4: fix open-create permissions
In the case where an open creates the file, we shouldn't be rechecking
permissions to open the file; the open succeeds regardless of what the new
file's mode bits say.

This patch fixes the problem, but only by introducing yet another parameter
to nfsd_create_v3.  This is ugly.  This will be fixed by later patches.

Steve French 6e659c6399 [CIFS] Fix mount failure when domain not specified
Fixes Samba bugzilla #4176

    When users do not specify their domain on mount, 2.6.18 started sending
    default domain instead of a null domain (which was the only way on some
    servers to use a default domain).  Users of 2.6.18 who did not specify
    their domain name on mounts to certain common Windows servers that were
    members of a domain, but not the domain controller, would get mount
    failures which they did not get in 2.6.18

    This fixes that issue and should remove complaints about mount
    behavior changing.

Patrick Caulfield e2de7f5655 [DLM] fix oops in kref_put when removing a lockspace
Now that the lockspace struct is freed when the last sysfs object is released
this patch prevents use of that lockspace by sysfs. We attempt to re-get the
lockspace from the lockspace list and fail the request if it has been removed.

This patch fixes the recounting on the lockspace kobject. Previously the lockspace was freed while userspace could have had a
reference to one of its sysfs files, causing an oops in kref_put.

Now the lockspace kfree is moved into the kobject release() function

This adds a sync_fs superblock operation for GFS2 and removes
the journal flush from write_super in favour of sync_fs where it
ought to be. This is more or less identical to the way in which ext3
does this.
