[ Upstream commit 79a7482249a7353bc86aff8127954d5febf02472 ]
Both cxgb4 and csiostor drivers run on their own independent Physical
Function. But when cxgb4 and csiostor are both being loaded in parallel via
modprobe, there is a race when firmware upgrade is attempted by both the
drivers.
When the cxgb4 driver initiates the firmware upgrade, it halts the firmware
and the chip until upgrade is complete. When the csiostor driver is coming
up in parallel, the firmware mailbox communication fails with timeouts and
the csiostor driver probe fails.
Add a module soft dependency on cxgb4 driver to ensure loading csiostor
triggers cxgb4 to load first when available to avoid the firmware upgrade
race.

[ Upstream commit 4a0a542fe5e4273baf9228459ef3f75c29490cba ]
The MSI-X and MSI calls fails in kdump kernel. Because of this
qla2xxx_create_qpair() fails leading to .create_queue callback failure.
The fix is to return existing qpair instead of allocating new one and
allocate a single hw queue.

[ Upstream commit 4e28550829258f7dab97383acaa477bd724c0ff4 ]
ISCSI_NET_PARAM_IFACE_ENABLE belongs to enum iscsi_net_param instead of
iscsi_iface_param so move it to ISCSI_NET_PARAM. Otherwise, when we call
into the driver, we might not match and return that we don't want attr
visible in sysfs. Found in code review.

commit 7215e909814fed7cda33c954943a4050d8348204 upstream.
Reporting zones on a SCSI device sometimes fail with the following error:
[76248.516390] ata16.00: invalid transfer count 131328
[76248.523618] sd 15:0:0:0: [sda] REPORT ZONES start lba 536870912 failed
The error (from drivers/ata/libata-scsi.c:ata_scsi_zbc_in_xlat()) indicates
that buffer size is not aligned to SECTOR_SIZE.
This happens when the __vmalloc() failed. Consider we are reporting 4096
zones, then we will have "bufsize = roundup((4096 + 1) * 64,
SECTOR_SIZE)" = (513 * 512) = 262656. Then, __vmalloc() failure halves
the bufsize to 131328, which is no longer aligned to SECTOR_SIZE.
Use rounddown() to ensure the size is always aligned to SECTOR_SIZE and fix
the comment as well.

commit c8fadf019964d0eb1da410ba8b629494d3339db9 upstream.
The first invocation of function find_first_zero_bit will return 0 and
queue_id gets set to 0.
An index of queue_pair_map also gets set to 0.
qpair_id = find_first_zero_bit(ha->qpair_qid_map, ha->max_qpairs);
set_bit(qpair_id, ha->qpair_qid_map);
ha->queue_pair_map[qpair_id] = qpair;
In the alloc_queue callback driver checks the map, if queue is already
allocated:
ha->queue_pair_map[qidx]
This works fine as long as max_qpairs is greater than nvme_max_hw_queues(8)
since the size of the queue_pair_map is equal to max_qpair. In case nr_cpus
is less than 8, max_qpairs is less than 8. This creates wrong value
returned as qpair.

[ Upstream commit ccc89737aa6b9f248cf1623014038beb6c2b7f56 ]
This driver has some left over "return 1" on failure style code mixed with
"return negative error codes" style code. The caller doesn't care so we
should just convert everything to return negative error codes.
Then there was a problem that there were two variables used to store error
codes which just resulted in confusion. If qedf_alloc_bdq() returned a
negative error code, we accidentally returned success instead of
propagating the error code. So get rid of the "rc" variable and use
"status" every where.
Also remove the "status = 0" initialization so that these sorts of bugs
will be detected by the compiler in the future.

[ Upstream commit 4dbe57d46d54a847875fa33e7d05877bb341585e ]
This function had some left over code that returned 1 on error instead
negative error codes. Convert everything to use negative error codes. The
caller treats all non-zero returns the same so this does not affect run
time.
A couple places set "rc" instead of "status" so those error paths ended up
returning success by mistake. Get rid of the "rc" variable and use
"status" everywhere.
Remove the bogus "status = 0" initialization, as a future proofing measure
so the compiler will warn about uninitialized error codes.

If param_offset > buff_len then the memcpy() statement in
ufshcd_read_desc_param() corrupts memory since it copies 256 + buff_len -
param_offset bytes into a buffer with size buff_len. Since param_offset <

commit 02c6dcd543f8f051973ee18bfbc4dc3bd595c558 upstream.
We found a hang, the steps to reproduce are as follows:
1. blocking device via scsi_device_set_state()
2. dd if=/dev/sda of=/mnt/t.log bs=1M count=10
3. echo none > /sys/block/sda/queue/scheduler
4. echo "running" >/sys/block/sda/device/state
Step 3 and 4 should complete after step 4, but they hang.

[ Upstream commit f0f82e2476f6adb9c7a0135cfab8091456990c99 ]
After adding physical volumes to a volume group through vgextend, the
kernel will rescan the partitions. This in turn will cause the device
capacity to be queried.
If the device status is set to offline through sysfs at this time, READ
CAPACITY command will return a result which the host byte is
DID_NO_CONNECT, and the capacity of the device will be set to zero in
read_capacity_error(). After setting device status back to running, the
capacity of the device will remain stuck at zero.
Fix this issue by rescanning device when the device state changes to
SDEV_RUNNING.

Avoid printing a 'target allocation failed' error if the driver
target_alloc() callback function returns -ENXIO. This return value
indicates that the corresponding H:C:T:L entry is empty.
Removing this error reduces the scan time if the user issues SCAN_WILD_CARD
scan operation through sysfs parameter on a host with a lot of empty
H:C:T:L entries.
Avoiding the printk on -ENXIO matches the behavior of the other callback
functions during scanning.

The list_for_each_entry() iterator, "adapter" in this code, can never be

"adapter" points invalid memory that is an offset from the list head. This
will eventually lead to memory corruption and presumably a kernel crash.

Media event code 3 is defined in the MMC-6 spec as follows:
"MediaRemoval: The media has been removed from the specified slot, and
the Drive is unable to access the media without user intervention. This
applies to media changers only."
This indicated that treating the condition as an EJECT_REQUEST was
appropriate. However, doing so had the unfortunate side-effect of causing
the drive tray to be physically ejected on resume. Instead treat the event
as a MEDIA_CHANGE request.

A ISCSI_IFACE_PARAM can have the same value as a ISCSI_NET_PARAM so when
iscsi_iface_attr_is_visible tries to figure out the type by just checking
the value, we can collide and return the wrong type. When we call into the
driver we might not match and return that we don't want attr visible in
sysfs. The patch fixes this by setting the type when we figure out what the

[ Upstream commit 49da96d77938db21864dae6b7736b71e96c1d203 ]
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.

[ Upstream commit 332a9dd1d86f1e7203fc7f0fd7e82f0b304200fe ]
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.

[ Upstream commit 030e4138d11fced3b831c2761e4cecf347bae99c ]
If an error occurs after a pci_enable_pcie_error_reporting() call, it must
be undone by a corresponding pci_disable_pcie_error_reporting() call, as
already done in the remove function.

[ Upstream commit 52e1b3b3daa9d53f0204bf474ee1d4b1beb38234 ]
Hyper-V is observed to sometimes set multiple flags in the srb_status, such
as ABORTED and ERROR. Current code in storvsc_handle_error() handles only a
single flag being set, and does nothing when multiple flags are set. Fix
this by changing the case statement into a series of "if" statements
testing individual flags. The functionality for handling each flag is
unchanged.

[ Upstream commit 0c72191da68638a479602dd515b587ada913184a ]
Drivers shouldn't be calling block/unblock session for cmd cleanup because
the functions can change the session state from under libiscsi. This adds
a new a driver level bit so it can block all I/O the host while it drains
the card.

[ Upstream commit 2819b4ae2873d50fd55292877b0231ec936c3b2e ]
Drivers shouldn't be calling block/unblock session for tmf handling because
the functions can change the session state from under libiscsi.
iscsi_queuecommand's call to iscsi_prep_scsi_cmd_pdu->
iscsi_check_tmf_restrictions will prevent new cmds from being sent to qedi
after we've started handling a TMF. So we don't need to try and block it in
the driver, and we can remove these block calls.
