2021-08-17scsi: target: Allows backend drivers to fail with specific sense codesSergey Samoylenko1-3/+12
Currently, backend drivers can fail I/O with SAM_STAT_CHECK_CONDITION which gets us TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE. Add a new helper that allows backend drivers to fail with specific sense codes. This is based on a patch from Mike Christie <michael.christie@oracle.com>.

2021-08-17scsi: smartpqi: Replace one-element array with flexible-array memberGustavo A. R. Silva2-3/+2
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members"[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code a bit according to the use of a flexible-array member in struct pqi_event_config instead of a one-element array, and use the struct_size() helper. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy(). This issue was found with the help of Coccinelle and audited and fixed, manually.

2021-08-17scsi: target: pscsi: Fix possible null-pointer dereference in ↵Tuo Li1-9/+9
pscsi_complete_cmd() The return value of transport_kmap_data_sg() is assigned to the variable buf: buf = transport_kmap_data_sg(cmd); And then it is checked: if (!buf) { This indicates that buf can be NULL. However, it is dereferenced in the following statements: if (!(buf[3] & 0x80)) buf[3] |= 0x80; if (!(buf[2] & 0x80)) buf[2] |= 0x80; To fix these possible null-pointer dereferences, dereference buf and call transport_kunmap_data_sg() only when buf is not NULL.

2021-08-16scsi: qedf: Fix error codes in qedf_alloc_global_queues()Dan Carpenter1-5/+5
This driver has some left over "return 1" on failure style code mixed with "return negative error codes" style code. The caller doesn't care so we should just convert everything to return negative error codes. Then there was a problem that there were two variables used to store error codes which just resulted in confusion. If qedf_alloc_bdq() returned a negative error code, we accidentally returned success instead of propagating the error code. So get rid of the "rc" variable and use "status" every where. Also remove the "status = 0" initialization so that these sorts of bugs will be detected by the compiler in the future.

This function had some left over code that returned 1 on error instead negative error codes. Convert everything to use negative error codes. The caller treats all non-zero returns the same so this does not affect run time. A couple places set "rc" instead of "status" so those error paths ended up returning success by mistake. Get rid of the "rc" variable and use "status" everywhere. Remove the bogus "status = 0" initialization, as a future proofing measure so the compiler will warn about uninitialized error codes.

2021-08-11scsi: qla2xxx: Sync queue idx with queue_pair_map idxSaurav Kashyap1-2/+3
The first invocation of function find_first_zero_bit will return 0 and queue_id gets set to 0. An index of queue_pair_map also gets set to 0. qpair_id = find_first_zero_bit(ha->qpair_qid_map, ha->max_qpairs); set_bit(qpair_id, ha->qpair_qid_map); ha->queue_pair_map[qpair_id] = qpair; In the alloc_queue callback driver checks the map, if queue is already allocated: ha->queue_pair_map[qidx] This works fine as long as max_qpairs is greater than nvme_max_hw_queues(8) since the size of the queue_pair_map is equal to max_qpair. In case nr_cpus is less than 8, max_qpairs is less than 8. This creates wrong value returned as qpair.

2021-08-11scsi: qedi: Add support for fastpath doorbell recoveryShai Malin3-12/+39
Driver fastpath employs doorbells to indicate to the device that work is available. Each doorbell translates to a message sent to the device over PCI. These messages are queued by the doorbell queue HW block, and handled by the HW. If a sufficient amount of CPU cores are sending messages at a sufficient rate, the queue can overflow, and messages can be dropped. There are many entities in the driver which can send doorbell messages. When overflow happens, a fatal HW attention is indicated, and the Doorbell HW block stops accepting new doorbell messages until recovery procedure is done. When overflow occurs, all doorbells are dropped. Since doorbells are aggregatives, if more doorbells are sent nothing has to be done. But if the "last" doorbell is dropped, the doorbelling entity doesn’t know this happened, and may wait forever for the device to perform the action. The doorbell recovery mechanism addresses just that - it sends the last doorbell of every entity.
