When an FC-GS I/O is aborted by lpfc, the driver requires a node pointer for a dereference operation. In the abort I/O routine, the driver miscasts a context pointer to the wrong data type and overwrites a single byte outside of the allocated space. This miscast is done in the abort I/O function handler because the handler works on both FC-GS and FC-LS commands. However, the code neglected to get the correct job location for the node. Fix this by acquiring the necessary node pointer from the correct job structure depending on the I/O type.

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. 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.
