> From: Rick Farrington <ricardo.farring...@cavium.com> > > 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[0]' in > octeon_setup_output_queues() and 'oct->instr_queue[0]' in > octeon_setup_instr_queues(). > > change log: > V1 -> V2: > 1. Corrected syntax in 'Subject' lines; no functional or code changes. Series applied. I removed the "[0]" in this commit log message. Thanks.
