In sg_common_write(), we free the block request and return -ENODEV if
the device is detached in the middle of the SG_IO ioctl().
Unfortunately, sg_finish_rem_req() also tries to free srp->rq, so we
end up freeing rq->cmd in the already free rq object, and then free
the object itself out from under the current user.
This ends up corrupting random memory via the list_head on the rq
object. The most common crash trace I saw is this:
------------[ cut here ]------------

The solution is straightforward: just set srp->rq to NULL in the
failure branch so that sg_finish_rem_req() doesn't attempt to re-free
it.
Additionally, since sg_rq_end_io() will never be called on the object
when this happens, we need to free memory backing ->cmd if it isn't
embedded in the object itself.
KASAN was extremely helpful in finding the root cause of this bug.

If MSI(X) interrupts are disabled via the kernel command line
(pci=nomsi), the pm8001 driver will kernel panic because it does not
detect that MSI interrupts are disabled and will soldier on and attempt to
configure MSI interrupts anyways. This leads to a kernel panic, most
likely because a required data structure is not available down the
line. Using the pci_msi_enabled() function in order to detect if MSI
interrupts are enabled before configuring them resolves this issue and
avoids a kernel panic when the module is loaded. Additionally, the
irq_vector structure must be initialized when legacy interrupts are
being used otherwise legacy interrupts will simply not function and
result in another panic.

Previuosly, all PMC Sierra 80xx controllers are assumed to be a
motherboard controller, except if the subsystem vendor ID was equal to
PCI_VENDOR_ID_ADAPTEC. The driver then attempts to load PHY settings
from NVRAM. While this may be correct behavior for most controllers, it
does not work with Adaptec and ATTO controllers since they do not store
PHY settings in NVRAM and choose to use either custom PHY settings or
chip defaults. Loading random values from NVRAM may cause the
controllers to malfunction in this edge case.

This patch fixes an issue seen with an IBM 2145 (SVC) where, following an error
injection test which results in paths going offline, when they came
back online, the path would timeout the REPORT_LUNS issued during the
scan. This timeout situation continued until retries were expired, resulting in
falling back to a sequential LUN scan. Then, since the target responds
with PQ=1, PDT=0 for all possible LUNs, due to the way the sequential
LUN scan code works, we end up adding 512 LUNs for each target, when there
is really only a small handful of LUNs that are actually present.
This patch increases the timeout used on the REPORT_LUNS to 30 seconds.
This patch solves the issue of 512 non existent LUNs showing up after
this event.

Implemented JBOD map which will provide quick access for JBOD path and
also provide sequence number. This will help hardware to fail command
to the FW in case of any sequence mismatch.
Fast Path I/O for JBOD will refer JBOD map (which has sequence number
per JBOD device) instead of RAID map. Previously, the driver used RAID
map to get device handle for fast path I/O and this not have sequence
number information. Now, driver will use JBOD map instead. As part of
error handling, if JBOD map is failed/not supported by firmware, driver
will continue using legacy behavior.
Now there will be three IO paths for JBOD (syspd):
- JBOD map with sequence number (Fast Path)
- RAID map without sequence number (Fast Path)
- FW path via h/w exception queue deliberately setup devhandle
0xFFFF (FW path).
Relevant data structures:
- Driver send new DCMD MR_DCMD_SYSTEM_PD_MAP_GET_INFO for this purpose.
- struct MR_PD_CFG_SEQ- This structure represent map of single physical
device.
- struct MR_PD_CFG_SEQ_NUM_SYNC- This structure represent whole JBOD
map in general(size, count of sysPDs configured, struct MR_PD_CFG_SEQ
of syspD with 0 index).
- JBOD sequence map size is: sizeof(struct MR_PD_CFG_SEQ_NUM_SYNC)
+ (sizeof(struct MR_PD_CFG_SEQ) * (MAX_PHYSICAL_DEVICES - 1)) which
is allocated while setting up JBOD map at driver load time.

The "compatible" matching algorithm used for looking up old-style
blacklist entries in a scsi_dev_info_list is buggy. The core of the
algorithm looks like this:
if (memcmp(devinfo->vendor, vendor,
min(max, strlen(devinfo->vendor))))
/* not a match */
where max is the length of the device's vendor string after leading
spaces have been removed but trailing spaces have not. Because of the
min() computation, either entry could be a proper substring of the
other and the code would still think that they match.
In the case originally reported, the device's vendor and product
strings were "Inateck " and " ". These matched against
the following entry in the global device list:
{"", "Scanner", "1.80", BLIST_NOLUN}
because "" is a substring of "Inateck " and "" (the result of removing
leading spaces from the device's product string) is a substring of
"Scanner". The mistaken match prevented the system from scanning and
finding the device's second Logical Unit.
This patch fixes the problem by making two changes. First, the code
for leading-space removal is hoisted out of the loop. (This means it
will sometimes run unnecessarily, but since a large percentage of all
lookups involve the "compatible" entries in global device list, this
should be an overall improvement.) Second and more importantly, the
patch removes trailing spaces and adds a check to verify that the two
resulting strings are exactly the same length. This prevents matches
where one entry is a proper substring of the other.
