The logic at get_atomisp_parameters32() is broken, as pointed by smatch: drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:737:21: warning: dereference of noderef expression drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:744:60: warning: dereference of noderef expression drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:763:21: warning: dereference of noderef expression drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:770:60: warning: dereference of noderef expression drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:788:21: warning: dereference of noderef expression drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:795:60: warning: dereference of noderef expression drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:812:21: warning: dereference of noderef expression drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:819:60: warning: dereference of noderef expression It tries to access userspace data directly, without calling get_user(). That should generate OOPS. Thankfully, the right logic is already there (although commented out). Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
