For example, when mount opt is redundently specified
(e.g., "user=A,user=B,user=C"), kernel kept allocating new key/val
with kstrdup() and overwrite previous ptr (to be freed).
Althouhg mount.cifs in userspace performs a bit of sanitization
(e.g., forcing one user option), current implementation is not
robust. Other options such as iocharset and domainanme are similarly
vulnerable.

Under intermittent network outages, find_writable_file() is susceptible
to the following race condition, which results in a user-after-free in
the cifs_writepages code-path:
Thread 1 Thread 2
======== ========
inv_file = NULL
refind = 0
spin_lock(&cifs_file_list_lock)
// invalidHandle found on openFileList
inv_file = open_file
// inv_file->count currently 1
cifsFileInfo_get(inv_file)
// inv_file->count = 2
spin_unlock(&cifs_file_list_lock);
cifs_reopen_file() cifs_close()
// fails (rc != 0) ->cifsFileInfo_put()
spin_lock(&cifs_file_list_lock)
// inv_file->count = 1
spin_unlock(&cifs_file_list_lock)
spin_lock(&cifs_file_list_lock);
list_move_tail(&inv_file->flist,
&cifs_inode->openFileList);
spin_unlock(&cifs_file_list_lock);
cifsFileInfo_put(inv_file);
->spin_lock(&cifs_file_list_lock)
// inv_file->count = 0
list_del(&cifs_file->flist);
// cleanup!!
kfree(cifs_file);
spin_unlock(&cifs_file_list_lock);
spin_lock(&cifs_file_list_lock);
++refind;
// refind = 1
goto refind_writable;
At this point we loop back through with an invalid inv_file pointer
and a refind value of 1. On second pass, inv_file is not overwritten on
openFileList traversal, and is subsequently dereferenced.

While attempting to clone a file on a samba server, we receive a
STATUS_INVALID_DEVICE_REQUEST. This is mapped to -EOPNOTSUPP which
isn't handled in smb2_clone_range(). We end up looping in the while loop
making same call to the samba server over and over again.
The proposed fix is to exit and return the error value when encountered
with an unhandled error.

Merge misc updates from Andrew Morton:
"Bite-sized chunks this time, to avoid the MTA ratelimiting woes.
- fs/notify updates
- ocfs2
- some of MM"
That laconic "some MM" is mainly the removal of remap_file_pages(),
which is a big simplification of the VM, and which gets rid of a *lot*
of random cruft and special cases because we no longer support the
non-linear mappings that it used.
From a user interface perspective, nothing has changed, because the
remap_file_pages() syscall still exists, it's just done by emulating the
old behavior by creating a lot of individual small mappings instead of
one non-linear one.
The emulation is slower than the old "native" non-linear mappings, but
nobody really uses or cares about remap_file_pages(), and simplifying
the VM is a big advantage.

Since "BDI: Provide backing device capability information [try #3]" the
backing_dev_info structure also provides flags for the kind of mmap
operation available in a nommu environment, which is entirely unrelated
to it's original purpose.
Introduce a new nommu-only file operation to provide this information to
the nommu mmap code instead. Splitting this from the backing_dev_info
structure allows to remove lots of backing_dev_info instance that aren't
otherwise needed, and entirely gets rid of the concept of providing a
backing_dev_info for a character device. It also removes the need for
the mtd_inodefs filesystem.

Commit
c11f1df5003d534fd067f0168bfad7befffb3b5c
requires writers to wait for any pending oplock break handler to
complete before proceeding to write. This is done by waiting on bit
CIFS_INODE_PENDING_OPLOCK_BREAK in cifsFileInfo->flags. This bit is
cleared by the oplock break handler job queued on the workqueue once it
has completed handling the oplock break allowing writers to proceed with
writing to the file.
While testing, it was noticed that the filehandle could be closed while
there is a pending oplock break which results in the oplock break
handler on the cifsiod workqueue being cancelled before it has had a
chance to execute and clear the CIFS_INODE_PENDING_OPLOCK_BREAK bit.
Any subsequent attempt to write to this file hangs waiting for the
CIFS_INODE_PENDING_OPLOCK_BREAK bit to be cleared.
We fix this by ensuring that we also clear the bit
CIFS_INODE_PENDING_OPLOCK_BREAK when we remove the oplock break handler
from the workqueue.
The bug was found by Red Hat QA while testing using ltp's fsstress
command.

It really needs to check that src is non-directory *and* use
{un,}lock_two_nodirectories(). As it is, it's trivial to cause
double-lock (ioctl(fd, CIFS_IOC_COPYCHUNK_FILE, fd)) and if the
last argument is an fd of directory, we are asking for trouble
by violating the locking order - all directories go before all
non-directories. If the last argument is an fd of parent
directory, it has 50% odds of locking child before parent,
which will cause AB-BA deadlock if we race with unlink().

In spite of different file type,
if file is same name and same inode number, old inode cache is used.
This causes that you can not cd directory, can not cat SymbolicLink.
So this patch is that if file type is different, return error.
Reproducible sample :
1. create file 'a' at cifs client.
2. repeat rm and mkdir 'a' 4 times at server, then direcotry 'a' having same inode number is created.
(Repeat 4 times, then same inode number is recycled.)
(When server is under RHEL 6.6, 1 time is O.K. Always same inode number is recycled.)
3. ls -li at client, then you can not cd directory, can not remove directory.
SymbolicLink has same problem.

A user complained that they were unable to login to their cifs share
after a kernel update. From the wiretrace we can see that the server
returns different UIDs as response to NTLMSSP_NEGOTIATE and NTLMSSP_AUTH
phases.
With changes in the authentication code, we no longer set the
cifs_sess->Suid returned in response to the NTLM_AUTH phase and continue
to use the UID sent in response to the NTLMSSP_NEGOTIATE phase. This
results in the server denying access to the user when the user attempts
to do a tcon connect.
