Use DEVICE_ATTR_RO() macro helper instead of plain DEVICE_ATTR(), which
makes the code a bit shorter and easier to read.

qedi_clear_session_ctx() could race with the in-kernel or userspace driven
recovery/removal and we could access a NULL conn or do a double free.
We should be using iscsi_host_remove() to start the removal process from
the driver. It will start the in-kernel recovery and notify userspace that
the driver's scsi_hosts are being removed. iscsid will then drive the
session removal like is done when the logout command is run. When the
sessions are removed, iscsi_host_remove() will return so qedi can finish
knowing there are no running sessions and no new sessions will be allowed.
This also fixes an issue where we check for a NULL conn after already
accessing it introduced in commit 27e986289e73 ("scsi: iscsi: Drop suspend
calls from ep_disconnect") by just removing the function completely.

If we got a response then we should always wake up the conn. For both the
cmd_cleanup_req == 0 or cmd_cleanup_req > 0, we shouldn't dig into
iscsi_itt_to_task because we don't know what the upper layers are doing.
We can also remove the qedi_clear_task_idx call here because once we signal
success libiscsi will loop over the affected commands and end up calling
the cleanup_task callout which will release it.

We need to make sure that abort and reset completion work has completed
before ep_disconnect returns. After ep_disconnect we can't manipulate
cmds because libiscsi will call conn_stop and take onwership.
We are trying to make sure abort work and reset completion work has
completed before we do the cmd clean up in ep_disconnect. The problem is
that:
1. the work function sets the QEDI_CONN_FW_CLEANUP bit, so if the work was
still pending we would not see the bit set. We need to do this before
the work is queued.
2. If we had multiple works queued then we could break from the loop in
qedi_ep_disconnect early because when abort work 1 completes it could
clear QEDI_CONN_FW_CLEANUP. qedi_ep_disconnect could then see that
before work 2 has run.
3. A TMF reset completion work could run after ep_disconnect starts
cleaning up cmds via qedi_clearsq. ep_disconnect's call to qedi_clearsq
-> qedi_cleanup_all_io would might think it's done cleaning up cmds,
but the reset completion work could still be running. We then return
from ep_disconnect while still doing cleanup.
This replaces the bit with a counter to track the number of queued TMF
works, and adds a bool to prevent new works from starting from the
completion path once a ep_disconnect starts.

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.

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.

qedi_iscsi_abort_work and qedi_tmf_work both allocate a tid then call
qedi_send_iscsi_tmf which also allocates a tid. This removes the tid

If qedi_tmf_work's qedi_wait_for_cleanup_request call times out we will
also force the clean up of the qedi_work_map but
qedi_process_cmd_cleanup_resp could still be accessing the qedi_cmd.
To fix this issue we extend where we hold the tmf_work_lock and back_lock
so the qedi_process_cmd_cleanup_resp access is serialized with the cleanup
done in qedi_tmf_work and any completion handling for the iscsi_task.

If the SCSI cmd completes after qedi_tmf_work calls iscsi_itt_to_task then
the qedi qedi_cmd->task_id could be freed and used for another cmd. If we
then call qedi_iscsi_cleanup_task with that task_id we will be cleaning up
the wrong cmd.
Wait to release the task_id until the last put has been done on the
iscsi_task. Because libiscsi grabs a ref to the task when sending the
abort, we know that for the non-abort timeout case that the task_id we are
referencing is for the cmd that was supposed to be aborted.
A latter commit will fix the case where the abort times out while we are
running qedi_tmf_work.

The iscsi offload drivers are setting the shost->max_id to the max number
of sessions they support. The problem is that max_id is not the max number
of targets but the highest identifier the targets can have. To use it to
limit the number of targets we need to set it to max sessions - 1, or we
can end up with a session we might not have preallocated resources for.

During ep_disconnect we have been doing iscsi_suspend_tx/queue to block new
I/O but every driver except cxgbi and iscsi_tcp can still get I/O from
__iscsi_conn_send_pdu() if we haven't called iscsi_conn_failure() before
ep_disconnect. This could happen if we were terminating the session, and
the logout timed out before it was even sent to libiscsi.
Fix the issue by adding a helper which reverses the bind_conn call that
allows new I/O to be queued. Drivers implementing ep_disconnect can use this
to make sure new I/O is not queued to them when handling the disconnect.

While aborting the I/O, the firmware cleanup task timed out and driver
deleted the I/O from active command list. Some time later the firmware
sent the cleanup task response and driver again deleted the I/O from

I/O and list_del corruption of active command list.
Add fix to check if I/O is present before deleting it from the active
command list to ensure firmware sends valid I/O completion and protect
against list_del corruption.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Smatch complains that the "path_data->handle" variable is user controlled.
It comes from iscsi_set_path() so that seems possible. It's harmless to
add a limit check.
The qedi->ep_tbl[] array has qedi->max_active_conns elements (which is
always ISCSI_MAX_SESS_PER_HBA (4096) elements). The array is allocated in
the qedi_cm_alloc_mem() function.

For an unreachable target, offload_work is not initialized and the endpoint
state is set to OFLDCONN_NONE. This results in a WARN_ON due to the check
of the work function field being set to zero.

While parsing the iSCSI TLV data to MFW request, a newline was added to the
firmware boot target iqnname string. Because of this, we were getting the
following error even after the boot target was successfully logged in:
"[qedi_get_protocol_tlv_data:1197]:1: Boot target not set"
Remove the trailing newline.

The new route handling in ip_mc_finish_output() from 'net' overlapped
with the new support for returning congestion notifications from BPF
programs.
In order to handle this I had to take the dev_loopback_xmit() calls
out of the switch statement.
The aquantia driver conflicts were simple overlapping changes.
