Hi,
Fedora got a bug report of a new permission denied error with 5.0-rc2:
File "/usr/lib/python3.7/site-packages/rtslib_fb/utils.py", line 100, in fread
with open(path, 'r') as file_fd:
PermissionError: [Errno 13] Permission denied: '/sys/kernel/config/target/core/fileio_28/xxx/attrib/pi_prot_format'
This looks like an intentional behavior change with
commit 6baca7601bdee2e57f20c45d63eb53b89b33e816

scsi: target: drop unused pi_prot_format attribute storage
On write, the pi_prot_format configfs attribute invokes the device
format_prot() callback if present. Read dumps the contents of
se_dev_attrib.pi_prot_format which is always zero. Make the configfs
attribute write-only, and drop the always zero se_dev_attrib.pi_prot_format
storage.

Unfortunately, existing code that's opening with read permissions is now broken.
Can this be reverted? Full bug at https://bugzilla.redhat.com/show_bug.cgi?id=1667505
Thanks,
