bcafad6c2d scsi: qla2xxx: Fix IOPS drop seen in some adapters
Removing the response queue processing in the send path is showing IOPS
drop. Add back the process_response_queue() call in the send path.

9e67600ed6 scsi: iscsi: Fix race condition between login and sync thread
A kernel panic was observed due to a timing issue between the sync thread
and the initiator processing a login response from the target. The session
reopen can be invoked both from the session sync thread when iscsid
restarts and from iscsid through the error handler. Before the initiator
receives the response to a login, another reopen request can be sent from
the error handler/sync session. When the initial login response is
subsequently processed, the connection has been closed and the socket has
been released.

To fix this a new connection state, ISCSI_CONN_BOUND, is added:

 - Set the connection state value to ISCSI_CONN_DOWN upon
   iscsi_if_ep_disconnect() and iscsi_if_stop_conn()

 - Set the connection state to the newly created value ISCSI_CONN_BOUND
   after bind connection (transport->bind_conn())

 - In iscsi_set_param(), return -ENOTCONN if the connection state is not
   either ISCSI_CONN_BOUND or ISCSI_CONN_UP

e8cfe8fa22 SCSI fixes on 20210327
Seven fixes, all in drivers (qla2xxx, mkt3sas, qedi, target,
 ibmvscsi).  The most serious are the target pscsi oom and the qla2xxx
 revert which can otherwise cause a use after free.

c2255ece2b scsi: pm8001: Avoid -Wrestrict warning
On some configurations, gcc warns about overlapping source and destination
arguments to snprintf:

drivers/scsi/pm8001/pm8001_init.c: In function 'pm8001_request_msix':
drivers/scsi/pm8001/pm8001_init.c:977:3: error: 'snprintf' argument 4 may overlap destination object 'pm8001_ha' [-Werror=restrict]
  977 |   snprintf(drvname, len, "%s-%d", pm8001_ha->name, i);
      |   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/pm8001/pm8001_init.c:962:56: note: destination object referenced by 'restrict'-qualified argument 1 was declared here
  962 | static u32 pm8001_request_msix(struct pm8001_hba_info *pm8001_ha)
      |                                ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~

I first assumed this was a gcc bug, as that should not happen, but a
reduced test case makes it clear that this happens when the loop counter is
not bounded by the array size.

Help the compiler out by adding an explicit limit here to make the code
slightly more robust and avoid the warning.

adb253433d scsi: bnx2i: Make bnx2i_process_iscsi_error() simpler and more robust
Instead of strcpy'ing into a stack buffer, just let additional_notice point
to a string literal living in .rodata. This is better in a few ways:

 - Smaller .text - instead of gcc compiling the strcpys as a bunch of
   immediate stores (effectively encoding the string literal in the
   instruction stream), we only pay the price of storing the literal in
   .rodata.

 - Faster, because there's no string copying.

 - Smaller stack usage (with my compiler, 72 bytes instead of 176 for the
   sole caller, bnx2i_indicate_kcqe)

Moreover, it's currently possible for additional_notice[] to get used
uninitialized, so some random stack garbage would be passed to printk() -
in the worst case without any '\0' anywhere in those 64 bytes. That could
be fixed by initializing additional_notice[0], but the same is achieved
here by initializing the new pointer variable to "".

Also give the message pointer a similar treatment - there's no point making
temporary copies on the stack of those two strings.

39c0c8553b scsi: Revert "qla2xxx: Make sure that aborted commands are freed"
Calling vha->hw->tgt.tgt_ops->free_cmd() from qlt_xmit_response() is wrong
since the command for which a response is sent must remain valid until the
SCSI target core calls .release_cmd(). It has been observed that the
following scenario triggers a kernel crash:

 - qlt_xmit_response() calls qlt_check_reserve_free_req()

 - qlt_check_reserve_free_req() returns -EAGAIN

 - qlt_xmit_response() calls vha->hw->tgt.tgt_ops->free_cmd(cmd)

 - transport_handle_queue_full() tries to retransmit the response

Fix this crash by reverting the patch that introduced it.

62fc266148 scsi: ibmvfc: Make ibmvfc_wait_for_ops() MQ aware
During MQ enablement of the ibmvfc driver ibmvfc_wait_for_ops() was
missed. This function is responsible for waiting on commands to complete
that match a certain criteria such as LUN or cancel key. The implementation
as is only scans the CRQ for events ignoring any sub-queues and as a result
will exit successfully without doing anything when operating in MQ
channelized mode.

Check the MQ and channel use flags to determine which queues are
applicable, and scan each queue accordingly. Note in MQ mode SCSI commands
are only issued down sub-queues and the CRQ is only used for driver
specific management commands. As such the CRQ events are ignored when
operating in MQ mode with channels.

8b1c9b2025 scsi: ibmvfc: Fix potential race in ibmvfc_wait_for_ops()
For various EH activities the ibmvfc driver uses ibmvfc_wait_for_ops() to
wait for the completion of commands that match a given criteria be it
cancel key, or specific LUN. With recent changes commands are completed
outside the lock in bulk by removing them from the sent list and adding
them to a private completion list. This introduces a potential race in
ibmvfc_wait_for_ops() since the criteria for a command to be outstanding is
no longer simply being on the sent list, but instead not being on the free
list.

Avoid this race by scanning the entire command event pool and checking that
any matching command that ibmvfc needs to wait on is not already on the
free list.
