commit ef222f551e7c4e2008fc442ffc9edcd1a7fd8f63 upstream.
While performing certain power-off sequences, PCI drivers are called to
suspend and resume their underlying devices through PCI PM (power
management) interface. However the hardware does not support PCI PM
suspend/resume operations so system wide suspend/resume leads to bad MFW
(management firmware) state which causes various follow-up errors in driver
when communicating with the device/firmware.
To fix this driver implements PCI PM suspend handler to indicate
unsupported operation to the PCI subsystem explicitly, thus avoiding system
to go into suspended/standby mode.

commit 5a43b07a87835660f91d88a4db11abfea8c523b7 upstream.
fnic_clean_pending_aborts() was returning a non-zero value irrespective of
failure or success. This caused the caller of this function to assume that
the device reset had failed, even though it would succeed in most cases. As
a consequence, a successful device reset would escalate to host reset.

commit 175544ad48cbf56affeef2a679c6a4d4fb1e2881 upstream.
Hyper-V provides the ability to connect Fibre Channel LUNs to the host
system and present them in a guest VM as a SCSI device. I/O to the vFC
device is handled by the storvsc driver. The storvsc driver includes a
partial integration with the FC transport implemented in the generic
portion of the Linux SCSI subsystem so that FC attributes can be displayed
in /sys. However, the partial integration means that some aspects of vFC
don't work properly. Unfortunately, a full and correct integration isn't
practical because of limitations in what Hyper-V provides to the guest.
In particular, in the context of Hyper-V storvsc, the FC transport timeout
function fc_eh_timed_out() causes a kernel panic because it can't find the
rport and dereferences a NULL pointer. The original patch that added the
call from storvsc_eh_timed_out() to fc_eh_timed_out() is faulty in this
regard.
In many cases a timeout is due to a transient condition, so the situation
can be improved by just continuing to wait like with other I/O requests
issued by storvsc, and avoiding the guaranteed panic. For a permanent
failure, continuing to wait may result in a hung thread instead of a panic,
which again may be better.
So fix the panic by removing the storvsc call to fc_eh_timed_out(). This
allows storvsc to keep waiting for a response. The change has been tested
by users who experienced a panic in fc_eh_timed_out() due to transient
timeouts, and it solves their problem.
In the future we may want to deprecate the vFC functionality in storvsc
since it can't be fully fixed. But it has current users for whom it is
working well enough, so it should probably stay for a while longer.

commit 9426d3cef5000824e5f24f80ed5f42fb935f2488 upstream.
(lightly modified commit message mostly by Linus Torvalds)
The parsing code for /proc/scsi/scsi is disgusting and broken. We should
have just used 'sscanf()' or something simple like that, but the logic may
actually predate our kernel sscanf library routine for all I know. It
certainly predates both git and BK histories.
And we can't change it to be something sane like that now, because the
string matching at the start is done case-insensitively, and the separator
parsing between numbers isn't done at all, so *any* separator will work,
including a possible terminating NUL character.
This interface is root-only, and entirely for legacy use, so there is
absolutely no point in trying to tighten up the parsing. Because any
separator has traditionally worked, it's entirely possible that people have
used random characters rather than the suggested space.
So don't bother to try to pretty it up, and let's just make a minimal patch
that can be back-ported and we can forget about this whole sorry thing for
another two decades.
Just make it at least not read past the end of the supplied data.

commit 010c1e1c5741365dbbf44a5a5bb9f30192875c4c upstream.
The Hyper-V host is queried to get the max transfer size that it supports,
and this value is used to set max_sectors for the synthetic SCSI
controller. However, this max transfer size may be too large for virtual
Fibre Channel devices, which are limited to 512 Kbytes. If a larger
transfer size is used with a vFC device, Hyper-V always returns an error,
and storvsc logs a message like this where the SRB status and SCSI status
are both zero:
hv_storvsc <GUID>: tag#197 cmd 0x8a status: scsi 0x0 srb 0x0 hv 0xc0000001
Add logic to limit the max transfer size to 512 Kbytes for vFC devices.

struct MPI2_RAID_SCSI_IO_REQUEST ends with a single SGL, but expects to
copy multiple. Add a flexible array member so the compiler can reason about
the size of the memcpy(). This will avoid the run-time false positive

[ Upstream commit 4e81a6cba517cb33584308a331f14f5e3fec369b ]
In a SCSI request, storvsc pre-allocates space for up to
MAX_PAGE_BUFFER_COUNT physical frame numbers to be passed to Hyper-V. If
the size of the I/O request requires more PFNs, a separate memory area of
exactly the correct size is dynamically allocated.
But when the pre-allocated area is used, current code always passes
MAX_PAGE_BUFFER_COUNT PFNs to Hyper-V, even if fewer are needed. While
this doesn't break anything because the additional PFNs are always zero,
more bytes than necessary are copied into the VMBus channel ring buffer.
This takes CPU cycles and wastes space in the ring buffer. For a typical 4
Kbyte I/O that requires only a single PFN, 248 unnecessary bytes are
copied.
Fix this by setting the payload_sz based on the actual number of PFNs
required, not the size of the pre-allocated space.

[ Upstream commit db651ec22524eb8f9c854fbb4d9acd5d7e5be9e4 ]
A fabric controller can sometimes send an RDP request right before a link
down event. Because of this outstanding RDP request, the driver does not
remove the last reference count on its ndlp causing a potential leak of RPI
resources when devloss tmo fires.
In lpfc_cmpl_els_rsp(), modify the NPIV clause to always allow the
lpfc_drop_node() routine to execute when not registered with SCSI
transport.
This relaxes the contraint that an NPIV ndlp must be in a specific state in
order to call lpfc_drop node. Logic is revised such that the
lpfc_drop_node() routine is always called to ensure the last ndlp decrement
occurs.

Note:

A driver may require this feature for when SATA device per-SCSI cmnd

decides.

valid, which results in receiving only the 4-byte header for the

The root cause is traced to an error-handling path in qla2x00_probe_one()
when the adapter "base_vha" initialize failed. The fab_scan_rp "scan.l" is
used to record the port information and it is allocated in
qla2x00_create_host(). However, it is not released in the error handling
path "probe_failed".
Fix this by freeing the memory of "scan.l" when an error occurs in the
adapter initialization process.

[ Upstream commit d684a7a26f7d2c7122a4581ac966ed64e88fb29c ]
_base_allocate_sense_dma_pool() already prints out the sense pool
information, so don't print it a second time after calling it in
_base_allocate_memory_pools(). In addition the version in
_base_allocate_memory_pools() was using the wrong size value, sz, which was
last assigned when doing some nvme calculations instead of sense_sz to
determine the pool size in kilobytes.

When a physical disk is attached directly "without JBOD MAP support" (see
megasas_get_tm_devhandle()) then there is no real error handling in the
driver. Return FAILED instead of SUCCESS.
