2025-03-17scsi: 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.

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.

2025-02-24scsi: lpfc: switch lpfc_irq_rebalance() to using cpumask_next_wrap()Yury Norov
Calling cpumask_next_wrap_old() with starting CPU equal to wrapping CPU is the same as request to find next CPU, wrapping around if needed. cpumask_next_wrap() is the proper replacement for that. Reviewed-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: Yury Norov <yury.norov@gmail.com>
2025-02-24cpumask: deprecate cpumask_next_wrap()Yury Norov
The next patch aligns implementation of cpumask_next_wrap() with the find_next_bit_wrap(), and it changes function signature. To make the transition smooth, this patch deprecates current implementation by adding an _old suffix. The following patches switch current users to the new implementation one by one. No functional changes were intended. Signed-off-by: Yury Norov <yury.norov@gmail.com>
2025-02-23scsi: scsi_debug: Add support for partitioning the tapeKai Mäkisara
This patch adds support for MEDIUM PARTITION PAGE in MODE SELECT and the FORMAT MEDIUM command for tapes. After these additions, the virtual tape can be partitioned containing either one or two partitions. The POFM flag in the mode page is set, meaning that the FORMAT MEDIUM command must be used to create the partitioning defined in the mode page.

2025-02-23scsi: scsi_debug: Add write support with block lengths and 4 bytes of dataKai Mäkisara
The tape is implemented as fixed number (10 000) of 8-byte units. The first four bytes of a unit contains the type of the unit (data block, filemark or end-of-data mark). If the units is a data block, the first four bytes 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 tape can contain two partitions. Initially it is formatted as one partition consisting of all 10 000 units. This patch adds the WRITE(6) command for tapes and the WRITE FILEMARKS (6) command. The REWIND command is updated.
