| * qla2xxx: Fix NVMe entry_type for iocb packet on BE systemHimanshu Madhani2017-07-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes incorrect assignment for entry_type field for Continuation Type iocb packet on BE system. This was caught by -Woverflow warning on BE system compilation. For Continuation Type iocb driver needs to write complete 32 bit value to initialize other field members in structure to 0. Following warning is seen on BE system compile: drivers/scsi/qla2xxx/qla_nvme.c: In function 'qla2x00_start_nvme_mq': include/uapi/linux/byteorder/big_endian.h:32:26: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define __cpu_to_le32(x) ((__force __le32)__swab32((x))) [mkp: fixed typo] Signed-off-by: Himanshu Madhani <himanshu.madhani@cavium.com> Signed-off-by: Martin K.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When NVMe support is disabled, we get a couple of harmless warnings: drivers/scsi/qla2xxx/qla_nvme.c:667:13: error: 'qla_nvme_unregister_remote_port' defined but not used [-Werror=unused-function] drivers/scsi/qla2xxx/qla_nvme.c:634:13: error: 'qla_nvme_abort_all' defined but not used [-Werror=unused-function] drivers/scsi/qla2xxx/qla_nvme.c:604:12: error: 'qla_nvme_wait_on_rport_del' defined but not used [-Werror=unused-function] This replaces the preprocessor checks in the code with equivalent compiler conditionals, which lets gcc drop the unused functions without warning, and is nicer to read.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we allocate 3 sets of DMA memories from separate pools for each slot. This is inefficient in terms of memory usage (buffers are less than 1 page in size, so we lose due to alignment), and also time spent in doing 3 allocations + de-allocations per slot, instead of 1. To optimise, combine the 3 DMA buffers into a single buffer from a single pool.

| * scsi: cxlflash: Update debug prints in reset handlersMatthew R. Ochs2017-07-011-15/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device and host reset handler contain debug prints to help identify the entities being reset. Today these reset handlers are based on a SCSI EH design that uses a SCSI command reference as a means of identifying the target entity. As such, the debug trace includes the SCSI command pointer and associated CDB. This is not necessary as the SCSI command is simply the messenger in these scenarios. Refactor the debug prints in the host and reset handlers to only present information that is applicable given the function scope. Signed-off-by: Matthew R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current send_tmf() implementation is based on the caller providing a SCSI command reference. In reality all that is needed is a SCSI device reference as the routine uses a private command. Refactor send_tmf() to pass the private adapter configuration reference and a SCSI device reference. As a nice side effect, this will ease the burden of converting caller routines to be based solely off of a SCSI device reference. Signed-off-by: Matthew R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device_unregister() service used when cleaning up the character device is already responsible for the internal state associated with the device upon successful creation. As the cxlflash driver does not obtain a second reference to the character device, the explicit call to put_device() is not required and can lead to an inconsistent sysfs among other issues as the reference is no longer valid after the first put_device() is performed. Remove the unnecessary put_device() to remedy this issue. Fixes: a834a36b57d9 ("scsi: cxlflash: Create character device to provide host management interface") Signed-off-by: Matthew R.

| * scsi: Add STARGET_CREATED_REMOVE state to scsi_target_stateEwan D. Milne2017-07-013-4/+10

However, if an rport loss occurs while a target is being scanned, it can happen that scsi_remove_target() will be called while the starget is still in the STARGET_CREATED state. In this case, the starget->state will be set to STARGET_REMOVE, and as a result, scsi_target_reap_ref_release() will take the wrong path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libsas uses scsi_queue_work() to queue its internal event notifications. scsi_queue_work() can return -EINVAL if the work queue doesn't exist and it does call queue_work() which can return false if the work is already queued. Make the SAS event code capable of returning errors up to the caller, which is handy when changing to dynamically allocated work in libsas as well, as discussed here: https://lkml.org/lkml/2017/6/14/121.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added logic to change the login process into an optional PRIL step for FC-NVMe ports as a separate operation, such that we can change type to 0x28 (NVMe). Currently, the driver performs the PLOGI/PRLI together as one operation, but if the discovered port is an NVMe port then we first issue the PLOGI and then we issue the PRLI. Also, the fabric discovery logic was changed to mark each discovered FC NVMe port, so that we can register them with the FC-NVMe transport later.
