When a command to a W-LU is timed out via scsi, error handling will treat it as any other LU and send commands such as START_STOP with wrong format or task abort. Those commands are illegal for W-LU according to the UFS spec. To solve it, when an error is recognized those steps are skipped and the last step, reset and restore process, is initiated.

Although on most systems va_end is a no-op, it is good practice to use va_end on the function return path, especially since the va_start documenation states: "Each invocation of va_start() must be matched by a corresponding invocation of va_end() in the same function."

After TPE recovery, CID table needs to be repopulated as per CIDs in WRBQ creation responses. SGL handles table needs to be recreated for posting and its indices need to be resetted. This is achieved by calling beiscsi_cleanup_port when disabling and beiscsi_init_port in enabling port. Signed-off-by:

Added check in beiscsi_process_cq for pio_handle. pio_handle is cleared in beiscsi_put_wrb_handle. This catches any case where task gets cleaned up just before completion. Use back_lock before accessing pio_handle. Signed-off-by:

invalid bit in WRB indicates to FW that IO was invalidated before WRB was fetched from host memory. For SkyHawk, this invalid bit in WRB is at a different offset. Use amap_iscsi_wrb_v2 to mark invalid bit for SkyHawk. Signed-off-by:

Hold the reference of iscsi_task till invalidation completes. This prevents use of ICD when invalidation of that ICD is being processed. Use frwd_lock for iscsi_tasks looping and back_lock to access beiscsi_io_task structures. Rewrite mgmt_invalidation_icds to handle allocation and freeing of IOCTL buffer in one place. Signed-off-by:

Remove shared structure inv_tbl in phba for all sessions to post invalidation IOCTL. Always allocate and then free the table after use in reset handler. Abort handler needs just one instance so define it on stack. Add checks for BE_INVLDT_CMD_TBL_SZ to not exceed invalidation command table size in IOCTL. Signed-off-by:

There are two places where adpt_i2o_online_hba() is called. Both callers call adpt_i2o_delete_hba(pHba) if adpt_i2o_online_hba() fails and since we also free it here that causes a double free bug. Signed-off-by:

On loosely ordered memory systems (PPC for example), the WQE elements were being updated in memory, but not necessarily flushed before the separate doorbell was written to hw which would cause hw to dma the WQE element. Thus, the hardware occasionally received partially updated WQE data. Add the memory barrier after updating the WQE memory. Signed-off-by:

On I/O errors, the Windows driver doesn't set data_transfer_length on error conditions other than SRB_STATUS_DATA_OVERRUN. In these cases we need to set data_transfer_length to 0, indicating there is no data transferred. On SRB_STATUS_DATA_OVERRUN, data_transfer_length is set by the Windows driver to the actual data transferred. Reported-by:
