ae56fb1633 [PATCH] eCryptfs: CIFS nlink fixes
When CIFS is the lower filesystem, the old lower dentry needs to be explicitly
dropped from inside eCryptfs to force a revalidate.  In addition, when CIFS is
the lower filesystem, the inode attributes need to be copied back up from the
lower inode to the eCryptfs inode on an eCryptfs revalidate.

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.

ba8df43c0e [PATCH] autofs4: panic after mount fail
Resolve the panic on failed mount of an autofs filesystem originally
reported by Mao Bibo.

It addresses two issues that happen after the mount fail.  The first a NULL
pointer reference to a field (pipe) in the autofs superblock info structure
and second the lack of super block cleanup by the autofs and autofs4
modules.

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.

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.

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.

f1f2d8713d [PATCH] Fix user.* xattr permission check for sticky dirs
The user.* extended attributes are only allowed on regular files and
directories.  Sticky directories further restrict write access to the owner
and privileged users.  (See the attr(5) man page for an explanation.)

The original check in ext2/ext3 when user.* xattrs were merged was more
restrictive than intended, and when the xattr permission checks were moved
into the VFS, read access to user.* attributes on sticky directores ended
up being denied in addition.

	                return error;

	        if (!dir->i_op || !dir->i_op->rmdir)
        	        return -EPERM;

	        DQUOT_INIT(dir);

	        mutex_lock(&dentry->d_inode->i_mutex);
	...

So I have developed the patch to overcome this problem.

87c2b7c045 [PATCH] sys_pselect7 vs compat_sys_pselect7 uaccess error handling
758333458a fixes the not checked copy_to_user
return value of compat_sys_pselect7.  I ran into this too because of an old
source tree, but my fix would look quite a bit different to Andi's fix.

The reason is that the compat function IMHO should behave the very same as
the non-compat function if possible.  Since sys_pselect7 does not return
-EFAULT in this specific case, change the compat code so it behaves like
sys_pselect7.
