scsi: hpsa: Fix DMA mapping leak on IOACCEL2 reset path

2026-07-13T02:21:22Z

If phys_disk->in_reset is set, the function returns directly without undoing the resources acquired for the command. Add the missing error cleanup by unmapping the IOACCEL2 SG chain block when needed, unmapping the SCSI command, and dropping the outstanding IOACCEL command count before returning.

scsi: elx: efct: Fix refcount leak in efct_hw_io_abort()

2026-07-13T02:21:22Z

When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path returns -ENOSPC without releasing the reference obtained via kref_get_unless_zero() earlier in the function. All other error paths correctly drop the reference. This causes a permanent reference leak on the io_to_abort object. Additionally, the abort_in_progress flag is left set to true on this path, which means future abort attempts for the same I/O will immediately return -EINPROGRESS even though the abort was never submitted, effectively blocking recovery. Fix this by adding the missing kref_put() call and reset abort_in_progress to false, matching the cleanup done in the efct_hw_wq_write() failure path below.

scsi: elx: efct: Fix I/O leak on unsupported additional CDB

2026-07-13T02:21:22Z

efct_dispatch_fcp_cmd() allocates an efct_io before dispatching an unsolicited FCP command. If the command has an unsupported additional CDB, the function returns -EIO before handing the IO to the SCSI layer. Free the allocated IO before returning from this error path.

scsi: core: wake eh reliably when using scsi_schedule_eh

2026-07-13T02:21:22Z

Drivers which use the scsi_schedule_eh function to run the error handler currently risk the error handler thread never waking once all commands are timed out or inactive. There is no enforced memory order between setting the host into error recovery state and counting busy commands. This can result in a race with scsi_dec_host_busy where neither CPU sees both conditions of all commands inactive and the host error state to request waking the error handler. To fix this, run the scsi_schedule_eh's scsi_eh_wakeup from a new work item which will use rcu to ensure scsi_schedule_eh's call to scsi_host_busy will occur after the error state is globally visible and will be seen by any current scsi_dec_host_busy callers.

scsi: sg: Report request-table problems when any status is set

2026-07-09T01:59:45Z

SG_GET_REQUEST_TABLE reports per-request diagnostic state through sg_req_info::problem. The field is meant to indicate whether there is an error to report for a completed request. sg_fill_request_table() currently combines masked_status, host_status and driver_status with bitwise AND. This only reports a problem when all three status fields are non-zero at the same time. A normal target check condition, for example, has masked_status set while host_status and driver_status may both be zero, so the request is incorrectly reported as clean. Use the same condition as sg_new_read(), which sets SG_INFO_CHECK when any of the three status fields is non-zero.

treewide: fix transposed "sign" typos and update spelling.txt

2026-06-17T22:37:47Z

Several comments transpose the letters in "assigned" and "unsigned", spelling them with "sing" instead of "sign". Correct all of them. Of these, the misspelling of "assigned" is not yet flagged by checkpatch, so also add it to scripts/spelling.txt. The remaining matches of `grep -ri singed` are RISINGEDGE register and enum names, not typos.
