[ Upstream commit 25dbc20deab5165f847b4eb42f376f725a986ee8 ]
The qedf_dbg_fp_int_cmd_read() function invokes sprintf() directly on a
__user pointer, which may crash the kernel.
Avoid doing that by vmalloc()'ating a buffer for scnprintf() and then
calling simple_read_from_buffer() which does a proper copy_to_user() call.
Fixes: 61d8658b4a43 ("scsi: qedf: Add QLogic FastLinQ offload FCoE driver framework.")

qedf_dbg_stop_io_on_error_cmd_read() directly
[ Upstream commit 7d3d20dee4f648ec44e9717d5f647d594d184433 ]
The qedf_dbg_stop_io_on_error_cmd_read() function invokes sprintf()
directly on a __user pointer, which may crash the kernel.
Avoid doing that by using a small on-stack buffer for scnprintf() and then
calling simple_read_from_buffer() which does a proper copy_to_user() call.

Pull SCSI updates from James Bottomley:
"This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc,
xfcp, hisi_sas, cxlflash, qla2xxx.
In the absence of Nic, we're also taking target updates which are
mostly minor except for the tcmu refactor.
The only real core change to worry about is the removal of high page
bouncing (in sas, storvsc and iscsi). This has been well tested and no
problems have shown up so far"

The prototype for qedf_dbg_fops/qedf_debugfs_ops doesn't match the definition,
which causes the final link to fail with link-time optimizations:
drivers/scsi/qedf/qedf_main.c:34: error: type of 'qedf_dbg_fops' does not match original declaration [-Werror=lto-type-mismatch]
extern struct file_operations qedf_dbg_fops;
drivers/scsi/qedf/qedf_debugfs.c:443: note: 'qedf_dbg_fops' was previously declared here
const struct file_operations qedf_dbg_fops[] = {
drivers/scsi/qedf/qedf_main.c:33: error: type of 'qedf_debugfs_ops' does not match original declaration [-Werror=lto-type-mismatch]
extern struct qedf_debugfs_ops qedf_debugfs_ops;
drivers/scsi/qedf/qedf_debugfs.c:102: note: 'qedf_debugfs_ops' was previously declared here
struct qedf_debugfs_ops qedf_debugfs_ops[] = {
This corrects the prototype and moves it into a shared header file where it
belongs. The file operations can also be marked 'const' like the
qedf_debugfs_ops.

Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. These were identified during
allyesconfig builds of x86, arm, and arm64, with most initializer fixes
extracted from grsecurity.
For these cases, terminate the list with { }, which will be zero-filled,
instead of undesignated NULLs.
