Some older SCSI devices return a SCSI-2 style vpd page 0x83, instead of a SPC-2/3 format one. The SCSI-2 page 83 format returns an IEEE WWN in binary encoded hexi-decimal in the 16 bytes following the initial 4-byte page 83 reply header. Check the 7th byte of the vpd page 83 buffer to determine whether this is a SCSI-2 or SPC-2/3 confomant one. Byte 7 is the 3rd byte of first Identification descriptor in a SPC-2/3 confromant vpd page 83. This is a reserved field, and is guaranteed to be 0. If it is not zero, then it is likely the 3rd byte of a SCSI-2 Identifier (The first 3 bytes of the ID are the Organizationally Unique Identifier). Both the sg_inq and scsi_id commands handle vpd page 83 this way. To make sure that the WWID which multipath reads directly from the device matches, it should handle this format as well.

We map PATH_TIMEOUT to PATH_DOWN in pathinfo(), but not in get_new_state(). Do it there, too, to treat the states consistently. This avoids logging "checker timed out" twice in update_path_state(), even if log_checker_err is set to "once".

A crafted GPT table with num_partition_entries >= 0x02000000 can trigger
an integer overflow in kpartx. Fix it by casting one operand of the
multiplication to size_t.
Same as kernel commit c5082b70adfe ("partitions/efi: Fix integer overflow
in GPT size calculation").

(cherry picked from commit 15310a3)
A maliciously crafted partition table could cause an unnecessarily large memory allocation. By using mmap(), we can calculate the checksum without needing to allocate space for more than the supported number of partitions. Tested with odd values of MAX_SLICES like 1, 2, 4, 7, 8, 19.

The kernel prints an error message when a bio-based multipath device sets a hardware handler, since bio-based devices only support using the already attached hardware handler as-is. Change select_hwhandler() to not set a hardware handler for bio-based devices.

Update ALUA asymmetric access state descriptions in the prioritizer to
match the shorter names defined in the SCSI kernel subsystem:
$ grep "{ SCSI_ACCESS_STATE_" linux/drivers/scsi/scsi_sysfs.c
{ SCSI_ACCESS_STATE_OPTIMAL, "active/optimized" },
{ SCSI_ACCESS_STATE_ACTIVE, "active/non-optimized" },
{ SCSI_ACCESS_STATE_STANDBY, "standby" },
{ SCSI_ACCESS_STATE_UNAVAILABLE, "unavailable" },
{ SCSI_ACCESS_STATE_LBA, "lba-dependent" },
{ SCSI_ACCESS_STATE_OFFLINE, "offline" },
{ SCSI_ACCESS_STATE_TRANSITIONING, "transitioning" },
This unifies diagnostic strings across the stack and replaces the misleading
"ARRAY BUG: invalid TPGs state!" message with the standard SPC "reserved"
designation. These codes are explicitly reserved for future standard
definitions rather than being treated as malformed states.

Avoid that "git clang-format" wrongly indents the invocations of the macros make_test_vpd_str() and make_test_vpd_prespc3 in tests/vpd.c, by appending semicolons to the macro invocation as we did for other macros in the same file. Note: The indentation issue could also be fixed by adding these macros to the "StatementMacros:" directive in .clang-format. Signed-off-by: Martin Wilck <mwilck@suse.com>
