2021-06-22scsi: libsas: Add LUN number check in .slave_alloc callbackYufen Yu
Offlining a SATA device connected to a hisi SAS controller and then scanning the host will result in detecting 255 non-existent devices: # lsscsi [2:0:0:0] disk ATA Samsung SSD 860 2B6Q /dev/sda [2:0:1:0] disk ATA WDC WD2003FYYS-3 1D01 /dev/sdb [2:0:2:0] disk SEAGATE ST600MM0006 B001 /dev/sdc # echo "offline" > /sys/block/sdb/device/state # echo "- - -" > /sys/class/scsi_host/host2/scan # lsscsi [2:0:0:0] disk ATA Samsung SSD 860 2B6Q /dev/sda [2:0:1:0] disk ATA WDC WD2003FYYS-3 1D01 /dev/sdb [2:0:1:1] disk ATA WDC WD2003FYYS-3 1D01 /dev/sdh ... [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.

2021-06-22scsi: aic7xxx: Fix unintentional sign extension issue on left shift of u8Colin Ian King
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 f58eb66c0b0a ("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.

debugfs_create_xxx routines, which return pointers, are being checked for error by looking for NULL values. The routines may return pointer-munged -Exxx codes, so they should be using IS_ERR() to adapt. There are two cases: - The first case is on initial directory creation, which actually doesn't need to be checked. So remove the check. - Creation of the sessions subdirectory. Modify this creation to create under the initial directory created, and fix failure check.
