This reverts commit 84f7a9de0602704bbec774a6c7f7c8c4994bee9c.
Because it introduces a problem that rq->__data_len is set to the wrong
value.
before the patch:
1) nr_bytes = rq->__data_len
2) rq->__data_len = sdp->sector_size
3) scsi_init_io()
4) rq->__data_len = nr_bytes
after the patch:
1) rq->__data_len = sdp->sector_size
2) scsi_init_io()
3) rq->__data_len = rq->__data_len -> __data_len is wrong
It will cause that io can only complete one segment each time, and the io
will requeue in scsi_io_completion_action(), which will cause severe
performance degradation.
Scsi write same is removed in commit e383e16e84e9 ("scsi: sd: Remove
WRITE_SAME support") from mainline, hence this patch is only needed for
stable kernels.
Fixes: 84f7a9de0602 ("scsi: sd: Remove a local variable")

LTS 5.15 pulled in several lpfc "SLI Path split" patches. The Path
Split mods were a 14-patch set, which refactors the driver from
to split the sli-3 hw (now eol) from the sli-4 hw and use sli4
structures natively. The patches are highly inter-related.

where FLOGI's fail, thus SLI Ports can't start communication.

commit 0b863257c17c5f57a41e0a48de140ed026957a63 upstream.
One of the sysfs values reported for supported_speeds was not valid (20Gb/s
reported instead of 64Gb/s). Instead of driver internal speed mask
definition, use speed mask defined in transport_fc for reporting
host->supported_speeds.

[ Upstream commit dc8e483f684a24cc06e1d5fa958b54db58855093 ]
Commit 5e633302ace1 ("scsi: lpfc: vmid: Add support for VMID in mailbox
command") introduced allocations for the VMID resources in
lpfc_create_port() after the call to scsi_host_alloc(). Upon failure on the
VMID allocations, the new code would branch to the 'out' label, which
returns NULL without unwinding anything, thus skipping the call to
scsi_host_put().
Fix the problem by creating a separate label 'out_free_vmid' to unwind the
VMID resources and make the 'out_put_shost' label call only
scsi_host_put(), as was done before the introduction of allocations for
VMID.

The original code will "goto out_disable_device" and call
pci_disable_device() if pci_enable_device() fails. The kernel will generate
a warning message like "3w-9xxx 0000:00:05.0: disabling already-disabled

We shouldn't disable a device that failed to be enabled. A simple return is
fine.

[ Upstream commit 57569c37f0add1b6489e1a1563c71519daf732cf ]
Fix a NULL pointer crash that occurs when we are freeing the socket at the
same time we access it via sysfs.
The problem is that:
1. iscsi_sw_tcp_conn_get_param() and iscsi_sw_tcp_host_get_param() take
the frwd_lock and do sock_hold() then drop the frwd_lock. sock_hold()
does a get on the "struct sock".
2. iscsi_sw_tcp_release_conn() does sockfd_put() which does the last put
on the "struct socket" and that does __sock_release() which sets the
sock->ops to NULL.
3. iscsi_sw_tcp_conn_get_param() and iscsi_sw_tcp_host_get_param() then
call kernel_getpeername() which accesses the NULL sock->ops.
Above we do a get on the "struct sock", but we needed a get on the "struct
socket". Originally, we just held the frwd_lock the entire time but in
commit bcf3a2953d36 ("scsi: iscsi: iscsi_tcp: Avoid holding spinlock while
calling getpeername()") we switched to refcount based because the network
layer changed and started taking a mutex in that path, so we could no
longer hold the frwd_lock.
Instead of trying to maintain multiple refcounts, this just has us use a
mutex for accessing the socket in the interface code paths.

[ Upstream commit f1d269765ee29da56b32818b7a08054484ed89f2 ]
We don't always want to run the recv path from the network softirq because
when we have to have multiple sessions sharing the same CPUs, some sessions
can eat up the NAPI softirq budget and affect other sessions or users.
Allow us to queue the recv handling to the iscsi workqueue so we can have
the scheduler/wq code try to balance the work and CPU use across all
sessions' worker threads.
Note: It wasn't the original intent of the change but a nice side effect is
that for some workloads/configs we get a nice performance boost. For a
simple read heavy test:
fio --direct=1 --filename=/dev/dm-0 --rw=randread --bs=256K
--ioengine=libaio --iodepth=128 --numjobs=4
where the iscsi threads, fio jobs, and rps_cpus share CPUs we see a 32%
throughput boost. We also see increases for small I/O IOPs tests but it's
not as high.

[ Upstream commit 46ba53c30666717cb06c2b3c5d896301cd00d0c0 ]
When executing SMP task failed, the smp_execute_task_sg() calls del_timer()
to delete "slow_task->timer". However, if the timer handler
sas_task_internal_timedout() is running, the del_timer() in
smp_execute_task_sg() will not stop it and a UAF will happen. The process
is shown below:
(thread 1) | (thread 2)
smp_execute_task_sg() | sas_task_internal_timedout()
... |
del_timer() |
... | ...
sas_free_task(task) |
kfree(task->slow_task) //FREE|
| task->slow_task->... //USE
Fix by calling del_timer_sync() in smp_execute_task_sg(), which makes sure
the timer handler have finished before the "task->slow_task" is
deallocated.

[ Upstream commit fbfe96869b782364caebae0445763969ddb6ea67 ]
In __qedf_probe(), if qedf->cdev is NULL which means
qed_ops->common->probe() failed, then the program will goto label err1, and
scsi_host_put() will free lport->host pointer. Because the memory qedf
points to is allocated by libfc_host_alloc(), it will be freed by
scsi_host_put(). However, the if statement below label err0 only checks
whether qedf is NULL but doesn't check whether the memory has been freed.
So a UAF bug can occur.
There are two ways to reach the statements below err0. The first one is
described as before, "qedf" should be set to NULL. The second one is goto
"err0" directly. In the latter scenario qedf hasn't been changed and it has
the initial value NULL. As a result the if statement is not reachable in
any situation.

[ Upstream commit c0a50cd389c3ed54831e240023dd12bafa56b3a6 ]
When the driver hits an internal error condition returning DID_REQUEUE the
I/O will be retried on the same ITL nexus. This will inhibit multipathing,
resulting in endless retries even if the error could have been resolved by
using a different ITL nexus. Return DID_TRANSPORT_DISRUPTED to allow for
multipath to engage and route I/O to another ITL nexus.

This partially reverts commit d2b292c3f6fd ("scsi: qla2xxx: Enable ATIO
interrupt handshake for ISP27XX")
For some workloads where the host sends a batch of commands and then
pauses, ATIO interrupt coalesce can cause some incoming ATIO entries to be
ignored for extended periods of time, resulting in slow performance,
timeouts, and aborted commands.
Disable interrupt coalesce and re-enable the dedicated ATIO MSI-X
interrupt.

commit d957e7ffb2c72410bcc1a514153a46719255a5da upstream.
storvsc_error_wq workqueue should not be marked as WQ_MEM_RECLAIM as it
doesn't need to make forward progress under memory pressure. Marking this
workqueue as WQ_MEM_RECLAIM may cause deadlock while flushing a
non-WQ_MEM_RECLAIM workqueue. In the current state it causes the following

[ Upstream commit b1f707146923335849fb70237eec27d4d1ae7d62 ]
On some platforms, the current logic of relying on finding new packet
solely based on signature pattern can lead to driver reading stale
packets. Though this is a bug in those platforms, reduce such exposures by
limiting reading packets until the IN pointer.
Two module parameters are introduced:
ql2xrspq_follow_inptr:
When set, on newer adapters that has queue pointer shadowing, look for
response packets only until response queue in pointer.
When reset, response packets are read based on a signature pattern
logic (old way).
ql2xrspq_follow_inptr_legacy:
Like ql2xrspq_follow_inptr, but for those adapters where there is no
queue pointer shadowing.
