From: Rick Farrington <ricardo.farring...@cavium.com> This patchset addresses issues brought about by low memory conditions in a VM. These conditions were only seen when VM's were intentionally created with small amounts of memory (for stress testing).
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[0]' in octeon_setup_output_queues() and 'oct->instr_queue[0]' in octeon_setup_instr_queues(). drivers/net/ethernet/cavium/liquidio/octeon_device.c | 8 ++++---- drivers/net/ethernet/cavium/liquidio/octeon_droq.c | 6 ++++-- 2 files changed, 8 insertions(+), 6 deletions(-) -- 1.8.3.1
