commitf18fa5de5bupstream. This patch initialize stack variables which are used in frag_lowpan_compare_key to zero. In my case there are padding bytes in the structures ieee802154_addr as well in frag_lowpan_compare_key. Otherwise the key variable contains random bytes. The result is that a compare of two keys by memcmp works incorrect.

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.
