scsi: core: Improve type safety of scsi_rescan_device()

2023-10-10T20:00:35+00:00

[ Upstream commit 79519528a180c64a90863db2ce70887de6c49d16 ] Most callers of scsi_rescan_device() have the scsi_device pointer readily available. Pass a struct scsi_device pointer to scsi_rescan_device() instead of a struct device pointer. This change prevents that a pointer to another struct device would be passed accidentally to scsi_rescan_device(). Remove the scsi_rescan_device() declaration from the scsi_priv.h header file since it duplicates the declaration in .

scsi: aacraid: Reply queue mapping to CPUs based on IRQ affinity

2023-09-13T07:42:25+00:00

[ Upstream commit 9dc704dcc09eae7d21b5da0615eb2ed79278f63e ] Fix the I/O hang that arises because of the MSIx vector not having a mapped online CPU upon receiving completion. SCSI cmds take the blk_mq route, which is setup during init. Reserved cmds fetch the vector_no from mq_map after init is complete. Before init, they have to use 0 - as per the norm.

scsi: aacraid: Allocate cmd_priv with scsicmd

2023-03-10T08:34:28+00:00

commit 7ab734fc759828707dae22fe48b1eb4dcf70beea upstream. The aac_priv() helper assumes that the private cmd area immediately follows struct scsi_cmnd. Allocate this space as part of scsicmd, else there is a risk of heap overflow.

The main driver change that might cause issues on down the road is the conversion of some of our oldest surviving drivers to the DMA API (should only affect m68k).
