2025-02-18scsi: hpsa: Replace deprecated strncpy() with strscpy_pad()Thorsten Blum
strncpy() is deprecated for NUL-terminated destination buffers. Replace memset() and strncpy() with strscpy_pad() to copy the version string and fill the remaining bytes in the destination buffer with NUL bytes. This avoids zeroing the memory before copying the string. Compile-tested only.

2025-02-18scsi: hpsa: Remove deprecated and unnecessary strncpy()Thorsten Blum
While replacing strncpy() with strscpy(), Bart Van Assche pointed out that the code occurs inside sysfs write callbacks, which already uses NUL-terminated strings. This allows the string to be passed directly to sscanf() without requiring a temporary copy. Remove the deprecated and unnecessary strncpy() and the corresponding local variables, and pass the buffer buf directly to sscanf(). Replace sscanf() with kstrtoint() to silence checkpatch warnings. Compile-tested only.

2024-12-04scsi: Convert SCSI drivers to .sdev_configure()Bart Van Assche
The only difference between the .sdev_configure() and .slave_configure() methods is that the former accepts an additional 'limits' argument. Convert all SCSI drivers that define a .slave_configure() method to .sdev_configure(). This patch prepares for removing the .slave_configure() method. No functionality has been changed.

2024-12-04scsi: Rename .slave_alloc() and .slave_destroy()Bart Van Assche
Rename .slave_alloc() into .sdev_init() and .slave_destroy() into .sdev_destroy(). The new names make it clear that these are actions on SCSI devices. Make this change in the SCSI core, SCSI drivers and also in the ATA drivers. No functionality has been changed. This patch has been created as follows: * Change the text "slave_alloc" into "sdev_init" in all source files except those in drivers/net/ and Documentation/. * Change the text "slave_destroy" into "sdev_destroy" in all source files except those in drivers/net/ and Documentation/. * Rename lpfc_no_slave() into lpfc_no_sdev(). * Manually adjust whitespace where necessary to restore vertical alignment (dc395x driver and include/linux/libata.h).

2021-02-22scsi: hpsa: Correct dev cmds outstanding for retried cmdsDon Brace
Prevent incrementing device->commands_outstanding for ioaccel command retries that are driver initiated. If the command goes through the retry path, the device->commands_outstanding counter has already accounted for the number of commands outstanding to the device. Only commands going through function hpsa_cmd_resolve_events decrement this counter. - ioaccel commands go to either HBA disks or to logical volumes comprised of SSDs. The extra increment is causing device resets to hang. - Resets wait for all device outstanding commands to complete before returning. Replace unused field abort_pending with retry_pending. This is a maintenance driver so these changes have the least impact/risk.

2020-11-25scsi: hpsa: Use generic power managementVaibhav Gupta
Drivers should do only device-specific jobs. But in general, drivers using legacy PCI PM framework for .suspend()/.resume() have to manage many PCI PM-related tasks themselves which can be done by PCI Core itself. This brings extra load on the driver and it directly calls PCI helper functions to handle them. Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove unnecessary calls to the PCI Helper functions along with the legacy .suspend & .resume bindings.

2020-10-29scsi: hpsa: Fix memory leak in hpsa_init_one()Keita Suzuki
When hpsa_scsi_add_host() fails, h->lastlogicals is leaked since it is missing a free() in the error handler. Fix this by adding free() when hpsa_scsi_add_host() fails.

2020-03-26scsi: hpsa: correct race condition in offload enabledDon Brace
Correct race condition where ioaccel is re-enabled before the raid_map is updated. For RAID_1, RAID_1ADM, and RAID 5/6 there is a BUG_ON called which is bad. - Change event thread to disable ioaccel only. Send all requests down the RAID path instead. - Have rescan thread handle offload_enable. - Since there is only one rescan allowed at a time, turning offload_enabled on/off should not be racy. Each handler queues up a rescan if one is already in progress. - For timing diagram, offload_enabled is initially off due to a change (transformation: splitmirror/remirror), ... otbe = offload_to_be_enabled oe = offload_enabled Time Event Rescan Completion Request Worker Worker Thread Thread ---- ------ ------ ---------- ------- T0 | | + UA | T1 | + rescan started | 0x3f | T2 + Event | | 0x0e | T3 + Ack msg | | | T4 | + if (!dev[i]->oe && | | T5 | | dev[i]->otbe) | | T6 | | get_raid_map | | T7 + otbe = 1 | | | T8 | | | | T9 | + oe = otbe | | T10 | | | + ioaccel request T11 * BUG_ON T0 - I/O completion with UA 0x3f 0x0e sets rescan flag. T1 - rescan worker thread starts a rescan. T2 - event comes in T3 - event thread starts and issues "Acknowledge" message ... T6 - rescan thread has bypassed code to reload new raid map. ... T7 - event thread runs and sets offload_to_be_enabled ... T9 - rescan thread turns on offload_enabled. T10- request comes in and goes down ioaccel path. T11- BUG_ON. - After the patch is applied, ioaccel_enabled can only be re-enabled in the re-scan thread.
