There are two bugs in the follow-MAC code: * it treats the radiotap header as the 802.11 header (therefore it can't possibly work) * it doesn't verify that the skb data it accesses is actually present in the header, which is mitigated by the first point Fix this by moving all of this out into a separate function. This function copies the data it needs using skb_copy_bits() to make sure it can be accessed if it's paged, and offsets that by the possibly present vendor radiotap header. This also makes all those conditions more readable. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
