Hi,
CoverityScan found an issue with the following part of the patch:
- if (likely(!reserv))
- blk_mq_complete_request(rq, -ENODEV);
- else if (test_bit(MTIP_PF_IC_ACTIVE_BIT, &dd->port->flags)) {
+ if (likely(!reserv)) {
+ cmd->status = -ENODEV;
+ blk_mq_complete_request(rq, 0);
+ } else if (test_bit(MTIP_PF_IC_ACTIVE_BIT, &dd->port->flags)) {
The issue is:
static void mtip_no_dev_cleanup(struct request *rq, void *data, bool reserv)
{
struct driver_data *dd = (struct driver_data *)data;
struct mtip_cmd *cmd;
if (likely(!reserv)) {
cmd->status = -ENODEV;
CID 1430258 (#1 of 1): Uninitialized pointer write (UNINIT)4.
uninit_use: Using uninitialized value cmd.
..basically a null ptr dereference on cmd.
