11 daysscsi: st: Tighten the page format heuristics with MODE SELECTKai Mäkisara
In the days when SCSI-2 was emerging, some drives did claim SCSI-2 but did not correctly implement it. The st driver first tries MODE SELECT with the page format bit set to set the block descriptor. If not successful, the non-page format is tried. The test only tests the sense code and this triggers also from illegal parameter in the parameter list. The test is limited to "old" devices and made more strict to remove false alarms.

11 daysscsi: lpfc: Restore clearing of NLP_UNREG_INP in ndlp->nlp_flagEwan D. Milne
Commit 32566a6f1ae5 ("scsi: lpfc: Remove NLP_RELEASE_RPI flag from nodelist structure") introduced a regression with SLI-3 adapters (e.g. LPe12000 8Gb) where a Link Down / Link Up such as caused by disabling an host FC switch port would result in the devices remaining in the transport-offline state and multipath reporting them as failed. This problem was not seen with newer SLI-4 adapters. The problem was caused by portions of the patch which removed the functions __lpfc_sli_rpi_release() and lpfc_sli_rpi_release() and all their callers. This was presumably because with the removal of the NLP_RELEASE_RPI flag there was no need to free the rpi. However, __lpfc_sli_rpi_release() and lpfc_sli_rpi_release() which calls it reset the NLP_UNREG_INP flag. And, lpfc_sli_def_mbox_cmpl() has a path where __lpfc_sli_rpi_release() was called in a particular case where NLP_UNREG_INP was not otherwise cleared because of other conditions. Restoring the else clause of this conditional and simply clearing the NLP_UNREG_INP flag appears to resolve the problem with SLI-3 adapters. It should be noted that the code path in question is not specific to SLI-3, but there are other SLI-4 code paths which may have masked the issue.

11 daysscsi: hisi_sas: Fixed failure to issue vendor specific commandsXingui Yang
At present, we determine the protocol through the cmd type, but other cmd types, such as vendor-specific commands, default to the PIO protocol. This strategy often causes the execution of different vendor-specific commands to fail. In fact, for these commands, a better way is to use the protocol configured by the command's tf to determine its protocol.

2025-02-24scsi: scsi_debug: Do not sleep in atomic sectionsBart Van Assche
Function stop_qc_helper() is called while the debug_scsi_cmd lock is held, and from here we may call cancel_work_sync(), which may sleep. Sleeping in atomic sections is not allowed. Hence change the cancel_work_sync() call into a cancel_work() call. However now it is not possible to know if the work callback is running when we return. This is relevant for eh_abort_handler handling, as the semantics of that callback are that success means that we do not keep a reference to the scsi_cmnd - now this is not possible. So return FAIL when we are unsure if the callback still running.

Simplify command handling by moving struct sdebug_defer into the private SCSI command data instead of allocating it separately. The only functional change is that aborting a SCSI command now fails and is retried at a later time if the completion handler can't be cancelled.

This structure is not used, so delete it. It was originally intended for supporting checking for atomic writes overlapping with ongoing reads and writes, but that support never got added. SBC-4 r22 section 4.29.3.2 "Performing operations during an atomic write operation" describes two methods of handling overlapping atomic writes.

2025-02-24scsi: mpi3mr: Check admin reply queue from WatchdogRanjan Kumar
Admin reply processing can be called from multiple contexts. The driver uses an atomic flag for synchronization among multiple threads/context for draining the admin replies. Upon entering the admin processing routine, the driver will set the atomic flag and start reply processing. When exiting the routine, the driver resets the flag. However, there is a race condition when one thread (Thread 1) has processed replies and is about to reset the flag but in the meantime few more replies are posted and another thread (Thread 2) is called to process replies. Since the synchronization flag is still set, Thread 2 will return without processing replies and those new replies will not be flushed. Make the watchdog thread monitor cases where admin ISR/poll call returns due to another thread processing admin replies. If such an instance is found, make driver call admin ISR to drain replies (if any).

2025-02-24Merge patch series "scsi: scsi_debug: Add more tape support"Martin K. Petersen
Kai Mäkisara <Kai.Makisara@kolumbus.fi> says: Currently, the scsi_debug driver can create tape devices and the st driver attaches to those. Nothing much can be done with the tape devices because scsi_debug does not have support for the tape-specific commands and features. These patches add some more tape support to the scsi_debug driver. The end result is simulated drives with a tape having one or two partitions (one partition is created initially). The tape is implemented as fixed number (10 000) of 8-byte units. The first four bytes of a unit contain the type of the unit (data block, filemark or end-of-data mark). If the units is a data block, the first four bytes also contain the block length and the remaining four bytes the first bytes of written data. This allows the user to use tags to see that the read block is what it was supposed to be. The following SCSI operations are added or modified: FORMAT MEDIUM - added LOCATE - added MODE SELECT - modified to allow use without page(s) (just header and block descriptor) - store density and block size - partition page added MODE SENSE - modified to allow use without page(s) (just header and block descriptor) - set density and block size - partition page added READ BLOCK LIMITS - added READ POSITION - added READ - added tape support for READ (6) REWIND - modified to set the tape position SPACE - added START STOP (LOAD) - modified to return New Medium Unit Attention if tape loaded (not according to the standard, but enables testing this UA) WRITE - added tape support for WRITE (6) WRITE FILEMARKS - added Link: https://lore.kernel.org/r/20250213092636.2510-1-Kai.Makisara@kolumbus.fi Signed-off-by: Martin K.

Notice that cpumask_next() followed by cpumask_first() in the worst case of an empty mask may traverse the mask twice. Cpumask_next_wrap() takes care of that correctly.
