scsi: message: mptfc: Switch from pci_ to dma_ API
The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'mptfc_GetFcDevPage0()' GFP_KERNEL can be used because it is already used in this function and no lock is acquired in the between. When memory is allocated in 'mptfc_GetFcPortPage0()' and 'mptfc_GetFcPortPage1()' GFP_KERNEL can be used because they already call 'mpt_config()' which has an explicit 'might_sleep()'. While at it, also remove some useless casting. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Link: https://lore.kernel.org/r/95afc589713ade2110e7812159ce3e9ab453ec18.1623568121.git.christophe.jaillet@wanadoo.fr Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Martin K.

scsi: libsas: Add LUN number check in .slave_alloc callback

[2:0:1:255] disk ATA WDC WD2003FYYS-3 1D01 /dev/sdjb After a REPORT LUN command issued to the offline device fails, the SCSI midlayer tries to do a sequential scan of all devices whose LUN number is not 0. However, SATA does not support LUN numbers at all. Introduce a generic sas_slave_alloc() handler which will return -ENXIO for SATA devices if the requested LUN number is larger than 0 and make libsas drivers use this function as their .slave_alloc callback.

scsi: aic7xxx: Fix unintentional sign extension issue on left shift o…
…f u8 The shifting of the u8 integer returned fom ahc_inb(ahc, port+3) by 24 bits to the left will be promoted to a 32 bit signed int and then sign-extended to a u64. In the event that the top bit of the u8 is set then all then all the upper 32 bits of the u64 end up as also being set because of the sign-extension. Fix this by casting the u8 values to a u64 before the 24 bit left shift. [ This dates back to 2002, I found the offending commit from the git history git://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git, commit f58eb66 ("Update aic7xxx driver to 6.2.10...") ] Link: https://lore.kernel.org/r/20210621151727.20667-1-colin.king@canonical.com Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Martin K.

scsi: elx: efct: Fix vport list linkage in LIO backend
vport is linked onto the driver's vport list at allocation, but failure path fails to remove it from the list. Change location of linkage until after complete vport completion.

scsi: aha1740: Avoid over-read of sense buffer
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. SCtmp->sense_buffer is 96 bytes, but ecbptr->sense is 14 bytes. Instead of over-reading ecbptr->sense, copy only the actual contents and zero pad the remaining bytes, avoiding potential over-reads.

scsi: arcmsr: Avoid over-read of sense buffer
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. pcmd->sense_buffer is 96 bytes, and was being manually zero-filled. However, struct SENSE_DATA is 18 bytes, with ccb->arcmsr_cdb.SenseData only being 15 bytes, resulting in a 3 byte over-read. Copy only the contents of ccb->arcmsr_cdb.SenseData and zero fill the remainder, avoiding potential over-reads.
