[CIFS] CIFS should honour umask

2007-06-08T14:55:14+00:00

This patch makes CIFS honour a process' umask like other filesystems.
Of course the server is still free to munge the permissions if it wants
to; but the client will send the "right" permissions to begin with.

A few caveats:

1) It only applies to filesystems that have CAP_UNIX (aka support unix
extensions)
2) It applies the correct mode to the follow up CIFSSMBUnixSetPerms()
after remote creation

When mode to CIFS/NTFS ACL mapping is complete we can do the
same thing for that case for servers which do not
support the Unix Extensions.

[CIFS] Missing flag on negprot needed for some servers to force packet signing

2007-06-05T21:31:16+00:00

A related signature issue that I came across.
There's a bug in win2k that when NT error codes are not negotiated, the
server doesn't response that signatures are mandatory. Since there's
(currently) no way turn on signatures in such case, I had to force NT
error codes, so that this bug will not occur

[CIFS] fix mempool destroy done in wrong order in cifs error path

2007-06-04T16:14:59+00:00

Slab cache used as memory pool can not be destroyed before the memory
pool destruction. Because the memory pool still holds some objects and
kmem_cache_destroy() says "Can't free all objects".

[CIFS] Fix oops on failed cifs mount (in kthread_stop)

2007-05-23T14:45:36+00:00

If the cifs demultiplex thread wakes up and exits
(zeroing server->tsk) before kthread_stop is called, the
cifs_mount code could pass a null pointer to kthread_stop

Thanks to akpm, Dave Young and Shaggy for suggesting
earlier versions of this patch.

SLAB_CTOR_CONSTRUCTOR is always specified. No point in checking it.

header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07+00:00

Remove includes of  where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

slab allocators: Remove SLAB_DEBUG_INITIAL flag

2007-05-07T19:12:57+00:00

I have never seen a use of SLAB_DEBUG_INITIAL.  It is only supported by
SLAB.

I think its purpose was to have a callback after an object has been freed
to verify that the state is the constructor state again?  The callback is
performed before each freeing of an object.

I would think that it is much easier to check the object state manually
before the free.  That also places the check near the code object
manipulation of the object.

Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was
compiled with SLAB debugging on.  If there would be code in a constructor
handling SLAB_DEBUG_INITIAL then it would have to be conditional on
SLAB_DEBUG otherwise it would just be dead code.  But there is no such code
in the kernel.  I think SLUB_DEBUG_INITIAL is too problematic to make real
use of, difficult to understand and there are easier ways to accomplish the
same effect (i.e.  add debug code before kfree).

There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be
clear in fs inode caches.  Remove the pointless checks (they would even be
pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors.

This is the last slab flag that SLUB did not support.  Remove the check for
unimplemented flags from SLUB.
