Rick Farrington says: ==================== liquidio: avoid vm low memory crashes This patchset addresses issues brought about by low memory conditions in a VM. These conditions were not seen when the driver was exercised normally. Rather, they were brought about through manual fault injection. They are being included in the interest of hardening the driver against unforeseen circumstances. 1. Fix GPF in octeon_init_droq(); zero the allocated block 'recv_buf_list'. This prevents a GPF trying to access an invalid 'recv_buf_list[i]' entry in octeon_droq_destroy_ring_buffers() if init didn't alloc all entries. 2. Don't dereference a NULL ptr in octeon_droq_destroy_ring_buffers(). 3. For defensive programming, zero the allocated block 'oct->droq' in octeon_setup_output_queues() and 'oct->instr_queue' in octeon_setup_instr_queues(). change log: V1 -> V2: 1. Corrected syntax in 'Subject' lines; no functional or code changes. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
