2024-08-28Merge patch series "smartpqi updates"Martin K. Petersen
Don Brace <don.brace@microchip.com> says: These patches are based on Martin Petersen's 6.12/scsi-queue tree https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git 6.12/scsi-queue There are two functional changes: smartpqi-add-fw-log-to-kdump smartpqi-add-counter-for-parity-write-stream-requests There are three minor bug fixes: smartpqi-fix-stream-detection smartpqi-fix-rare-system-hang-during-LUN-reset smartpqi-fix-volume-size-updates The other two patches add PCI-IDs for new controllers and change the driver version. This set of changes consists of: * smartpqi-add-fw-log-to-kdump During a kdump, the driver tells the controller to copy its logging information to some pre-allocated buffers that can be analyzed later. This is a "feature" driven capability and is backward compatible with existing controller FW. This patch renames some prefixes for OFA (Online-Firmware Activation ofa_*) buffers to host_memory_*. So, not a lot of actual functional changes to smartpqi_init.c, mainly determining the memory size allocation. We added a function to notify the controller to copy debug data into host memory before continuing kdump. Most of the functional changes are in smartpqi_sis.c where the actual handshaking is done. * smartpqi-fix-stream-detection Correct some false write-stream detections. The data structure used to check for write-streams was not initialized to all 0's causing some false write stream detections. The driver sends down streamed requests to the raid engine instead of using AIO bypass for some extra performance. (Potential full-stripe write verses Read Modify Write). False detections have not caused any data corruption. Found by internal testing. No known externally reported bugs. * smartpqi-add-counter-for-parity-write-stream-requests Adding some counters for raid_bypass and write streams. These two counters are related because write stream detection is only checked if an I/O request is eligible for bypass (AIO). The bypass counter (raid_bypass_cnt) was moved into a common structure (pqi_raid_io_stats) and changed to type __percpu. The write stream counter is (write_stream_cnt) has been added to this same structure. These counters are __percpu counters for performance. We added a sysfs entry to show the write stream count. The raid bypass counter sysfs entry already exists. Useful for checking streaming writes. The change in the sysfs entry write_stream_cnt can be checked during AIO eligible write operations. * smartpqi-add-new-controller-PCI-IDs Adding support for new controller HW. No functional changes. * smartpqi-fix-rare-system-hang-during-LUN-reset We found a rare race condition that can occur during a LUN reset. We were not emptying our internal queue completely. There have been some rare conditions where our internal request queue has requests for multiple LUNs and a reset comes in for one of the LUNs. The driver waits for this internal queue to empty. We were only clearing out the requests for the LUN being reset so the request queue was never empty causing a hang. The Fix: For all requests in our internal request queue: Complete requests with DID_RESET for queued requests for the device undergoing a reset. Complete requests with DID_REQUEUE for all other queued requests. Found by internal testing. No known externally reported bugs. * smartpqi-fix-volume-size-updates The current code only checks for a size change if there is also a queue depth change. We are separating the check for queue depth and the size changes. Found by internal testing. No known bugs were filed. * smartpqi-update-version-to-2.1.30-031 No functional changes.

Correct stream detection by initializing the structure pqi_scsi_dev_raid_map_data to 0s. When the OS issues SCSI READ commands, the driver erroneously considers them as SCSI WRITES. If they are identified as sequential IOs, the driver then submits those requests via the RAID path instead of the AIO path. The 'is_write' flag might be set for SCSI READ commands also. The driver may interpret SCSI READ commands as SCSI WRITE commands, resulting in IOs being submitted through the RAID path. Note: This does not cause data corruption.

In the event of system crash, host driver notifies the firmware about the crash and firmware posts all the necessary logs in the pre-allocated host buffer for firmware debugging. Once firmware notifies the completion of the log uploading to the host memory and host continues with the OS crash dump saving.

2024-08-22scsi: Expand all create*_workqueue() invocationsBart Van Assche
The workqueue maintainer wants to remove the create*_workqueue() macros because these macros always set the WQ_MEM_RECLAIM flag and because these only support literal workqueue names. Hence this patch that replaces the create*_workqueue() invocations with the definition of this macro. The WQ_MEM_RECLAIM flag has been retained because I think that flag is necessary for workqueues created by storage drivers. This patch has been generated by running spatch and git clang-format. spatch has been invoked as follows: spatch --in-place --sp-file expand-create-workqueue.spatch $(git grep -lEw 'create_(freezable_|singlethread_|)workqueue' */scsi */ufs) The contents of the expand-create-workqueue.spatch file is as follows: @@ expression name; @@ -create_workqueue(name) +alloc_workqueue("%s", WQ_MEM_RECLAIM, 1, name) @@ expression name; @@ -create_freezable_workqueue(name) +alloc_workqueue("%s", WQ_FREEZABLE | WQ_UNBOUND | WQ_MEM_RECLAIM, 1, name) @@ expression name; @@ -create_singlethread_workqueue(name) +alloc_ordered_workqueue("%s", WQ_MEM_RECLAIM, name) Reviewed-by: Peter Wang <peter.wang@mediatek.com> Signed-off-by: Bart Van Assche <bvanassche@acm.org> Link: https://lore.kernel.org/r/20240822195944.654691-2-bvanassche@acm.org Signed-off-by: Martin K.

2024-08-22scsi: sd: Ignore command SYNCHRONIZE CACHE error if format in progressYihang Li
If formatting a suspended disk (such as formatting with different DIF type), the disk will be resuming first, and then the format command will submit to the disk through SG_IO ioctl. When the disk is processing the format command, the system does not submit other commands to the disk. Therefore, the system attempts to suspend the disk again and sends the SYNCHRONIZE CACHE command. However, the SYNCHRONIZE CACHE command will fail because the disk is in the formatting process. This will cause the runtime_status of the disk to error and it is difficult for user to recover it. Error info like: [ 669.925325] sd 6:0:6:0: [sdg] Synchronizing SCSI cache [ 670.202371] sd 6:0:6:0: [sdg] Synchronize Cache(10) failed: Result: hostbyte=0x00 driverbyte=DRIVER_OK [ 670.216300] sd 6:0:6:0: [sdg] Sense Key : 0x2 [current] [ 670.221860] sd 6:0:6:0: [sdg] ASC=0x4 ASCQ=0x4 To solve the issue, ignore the error and return success/0 when format is in progress.

The kref_put() function will call nport->release if the refcount drops to zero. The nport->release release function is _efc_nport_free() which frees "nport". But then we dereference "nport" on the next line which is a use after free. Re-order these lines to avoid the use after free.

2024-08-22scsi: aacraid: Fix double-free on probe failureBen Hutchings
aac_probe_one() calls hardware-specific init functions through the aac_driver_ident::init pointer, all of which eventually call down to aac_init_adapter(). If aac_init_adapter() fails after allocating memory for aac_dev::queues, it frees the memory but does not clear that member. After the hardware-specific init function returns an error, aac_probe_one() goes down an error path that frees the memory pointed to by aac_dev::queues, resulting.in a double-free.

2024-08-12Merge patch series "NCR5380: Bug fixes and other improvements"Martin K. Petersen
Finn Thain <fthain@linux-m68k.org> says: This series begins with some work on the mac_scsi driver to improve compatibility with SCSI2SD v5 devices. Better error handling is needed there because the PDMA hardware does not tolerate the write latency spikes which SD cards can produce. A bug is fixed in the 5380 core driver so that scatter/gather can be enabled in mac_scsi. Several patches at the end of this series improve robustness and correctness in the core driver. This series has been tested on a variety of mac_scsi hosts. A variety of SCSI targets was also tested, including Quantum HDD, Fujitsu HDD, Iomega FDD, Ricoh CD-RW, Matsushita CD-ROM, SCSI2SD and BlueSCSI.
