Fri, 14 Aug 2026 05:38:45 +0200

scsi: leapraid: Serialize firmware log mmap with teardownleapraid_fw_log_exit() waits for mmap_refcnt to reach zero before it freesthe firmware log buffer. leapraid_fw_mmap() checks host_removing, but itdoes not increment mmap_refcnt until after dma_mmap_coherent() succeeds andthe VMA open callback runs.Removal can set host_removing and observe a zero mmap_refcnt between thecheck and the VMA open. It can then free the coherent buffer while themmap path is still establishing a userspace mapping of it.Claim a temporary mmap reference while looking up the adapter underleapraid_adapter_lock. Removal deletes the adapter from the same lockedlist after setting host_removing, so a mapping is either rejected orincluded in the count that removal waits for. Drop the temporary referenceon the common exit path, after a successful VMA open has acquired thereference covering the VMA lifetime.Fixes: 5597088c9e79 ("scsi: leapraid: Add new SCSI driver")Signed-off-by: Linmao Li Reviewed-by: Dongdong Hao Link: https://patch.msgid.link/20260814033845.2971706-3-lilinmao@kylinos.cnSigned-off-by: Martin K.

970f69b6bf71562df5afcefb89c77b4e971d68de - scsi: leapraid: Balance host references for firmware log VMAs

Fri, 14 Aug 2026 05:38:44 +0200

scsi: leapraid: Balance host references for firmware log VMAsleapraid_fw_mmap() keeps the Scsi_Host reference obtained while looking upthe adapter for the lifetime of the initial VMA. The VMA close callbackdrops that reference.The open callback is also invoked when a VMA is duplicated or split, but itonly increments mmap_refcnt. Since every corresponding close callbackdrops a host reference, cloning the mapping can release the host whileanother VMA still refers to the adapter.Take a host device reference for every VMA open and release the lookupreference once the initial mapping has acquired its own reference. Useget_device() because a VMA can be cloned after the host enters SHOST_DEL;an existing VMA still pins the host at that point and open cannot fail.Fixes: 5597088c9e79 ("scsi: leapraid: Add new SCSI driver")Signed-off-by: Linmao Li Reviewed-by: Dongdong Hao Link: https://patch.msgid.link/20260814033845.2971706-2-lilinmao@kylinos.cnSigned-off-by: Martin K.

Fri, 07 Aug 2026 17:59:18 +0200

Merge patch series "scsi: Add LeapRAID driver support"Dongdong Hao says:This series adds the LeapRAID driver and its documentation.This version addresses issues reported by Sashiko and the kernel testrobot, as well as issues identified through internal testing. Because[PATCH v4 1/2] exceeded the line-count limit of the public Sashikoservice, it was not analyzed. We therefore deployed Sashiko locallywith an increased line-count limit to complete the analysis and havefixed all identified issues.Link: https://patch.msgid.link/cover.1785823793.git.doubled@leap-io-kernel.comSigned-off-by: Martin K.

Tue, 04 Aug 2026 09:02:25 +0200

scsi: leapraid: Add new SCSI driverThe LeapRAID driver provides support for LeapRAID PCIe RAID controllers,enabling communication between the host operating system, firmware, andhardware for efficient storage management.The driver is organized into several logical modules, each with a clearresponsibility:leapraid_os.c: Integrates with the Linux SCSI subsystem, handling hosttemplate callbacks, PCIe device probing, and initialization.leapraid_func.c: Contains low-level routines for firmware/hardwareinteraction, interrupt handling, and reset logic.leapraid_app.c: Provides the ioctl interface for user-space tools.leapraid_transport.c: Manages interactions with the SCSI transportlayer for SAS PHYs and ports.leapraid_func.h: Contains internal definitions shared among drivermodules.leapraid.h: Contains low-level hardware definitions fordriver/firmware interaction.The leapraid_probe() function orchestrates the setup: it allocates theadapter structure and SCSI host, configures hardware interfaces, andregisters it with the SCSI mid-layer. Following registration,scsi_scan_host() is invoked to initiate device discovery, with firmwarereporting devices via interrupt-driven events.This initial commit provides the necessary infrastructure forsubsequent development of full I/O path handling, error recovery,and advanced management features.Reviewed-by: Damien Le Moal Reviewed-by: Hannes Reinecke Signed-off-by: Dongdong Hao Link: https://patch.msgid.link/0cbc6245aabdc6e8c90587675e76ba316c5b549e.1785823793.git.doubled@leap-io-kernel.comSigned-off-by: Martin K.
