[PATCH 00/25] qla2xxx: Bug fixes and cleanups

[Himanshu Madhani]

Hi Martin, 

This series contains bug fixes and cleanups for the driver that we posted in 4.11. 

Patches 1-10 needs to go in 4.12.0-rcX. Rest of the patches can be queued to for-next branch.
Please let me know if the series is okay to be included in 4.12.0-rcX. if we are too late
for big series in rcX then would you please queue patches 10-25 for 4.13/scsi-queue.

Thanks,
Himnanshu

[PATCH 05/25] qla2xxx: Fix number of queue pairs creation for MQ

[Himanshu Madhani]

From: Sawan Chandak <sawan.chandak@cavium.com>

when driver is loaded with Multi Queue enabled, it was
noticed that there was one less queue pair created.

Following message would indicate this

"No resources to create additional q pair."

The result of one less queue pair means that system can crash,
if the block mq layer thinks there is an extra hardware queue
available, and the driver will use a NULL ptr qpair in that instance.

Following stack trace is seen in one of the crash

[PATCH 12/25] qla2xxx: Fix path recovery

[Himanshu Madhani]

From: Quinn Tran <quinn.tran@cavium.com>

If the port is moved/changed, current code would trigger
a deletion. If the port is already deleted, then do relogin.

[PATCH 13/25] tcm_qla2xxx: Do not allow aborted cmd to advance.

[Himanshu Madhani]

From: Quinn Tran <quinn.tran@cavium.com>

In case of hardware queue full, commands can loop between
TCM stack and tcm_qla2xx shim layers for retry. While command
is waiting for retry, task mgmt can get ahead and abort the
cmmand that encountered queue full condition. Fix this by
dropping the command, if task mgmt has already started the
command free process.

[PATCH 14/25] qla2xxx: Use flag PFLG_DISCONNECTED.

[Himanshu Madhani]

From: Sawan Chandak <sawan.chandak@cavium.com>

There is already flag defined PFLG_DISCONNECTED, which is set
for PCI or register disconnect error condition. There is no need to have
flag PCI_ERR, which has same purpose. Remove use of PCI_ERR flag and use
PFLG_DISCONNECTED flag during error condition.

[PATCH 16/25] qla2xxx: Fix name server relogin

[Himanshu Madhani]

From: Quinn Tran <quinn.tran@cavium.com>

Name server login is normally handle by FW. In some
rare case where one of the switches is being updated,
name server login could get affected. Trigger relogin
to name server when driver detects this condition.

[PATCH 18/25] qla2xxx: Turn on FW option for exchange check

[Himanshu Madhani]

From: Quinn Tran <quinn.tran@cavium.com>

Tell FW to track exchange/cmd state to prevent driver
from using stale exchange or exchange that is not meant
for this command.

[PATCH 19/25] qla2xxx: Replace ql2xexchoffld & ql_dm_tgt_ex_pct parameter

[Himanshu Madhani]

From: Quinn Tran <quinn.tran@cavium.com>

Replace driver parameters ql2xexchoffld & ql_dm_tgt_ex_pct with
ql2xtgtexchg & ql2xiniexchg for readability.

Previously, the ql2xexchoffld module parameter was used to control
the max number of exchanges to be offload onto host memory.
Module parameter ql_dm_tgt_ex_pct was used to control the percentage
of exchanges allocated to the Target side.

With the updated module parameters, users can control the exact number
of exchanges for either Initiator or Target. The exchange offload feature
will be automatically enabled when the total number of exchanges exceeds
2048 limit.

[PATCH 20/25] qla2xxx: Remove redundant code

[Himanshu Madhani]

From: Quinn Tran <quinn.tran@cavium.com>

During ABTS or Abort task, qla2xxx does a pre-search for
the se_cmd, based on command's tag. The same search is
performed by TCM. Remove the extra search from qla2xxx.

[PATCH 21/25] qla2xxx: Remove redundant wait when target is stopped.

[Himanshu Madhani]

From: Quinn Tran <quinn.tran@cavium.com>

Current code already destroy all target sessions when
target Mode is stopped. Target core would waits for
all commands that belong to each session to purge.
The extra wait for interrupts to settle down is not
relevant.

stop phase 2 is not using the correct vha pointer
for npiv case.

[PATCH 23/25] qla2xxx: Remove unused irq_cmd_count field.

[Himanshu Madhani]

From: Quinn Tran <quinn.tran@cavium.com>

When driver is unloaded, all sessions are torn down, all
commmands are flushed, chip is reset to ensure there is
no knowledge of target mode in ISP. The irq_cmd_count field
was used to make sure all commands are processed on top of that.
The irq_cmd_count is now redundant and not needed.

Hello Himanshu,

If the above host port name assignment is redundant, what is the host
port name assignment it is redundant with?

Which of the removed statements could trigger a NULL pointer access, and
from what context? Is there perhaps a call trace available of the NULL
pointer access?

Thanks,

Bart.

Hello Himanshu,

Sorry but this description sounds rather mysterious to me?

Hello Himanshu and Quinn,

Did you perhaps mean that the command lists can be accessed from interrupt
context? If so, please mention this in the patch description.

Thanks,

Hello Himanshu and Quinn,

A LIO target driver should not make any assumptions about whether or not LUN 0
exists. Please modify this patch such that the LUN through which the task
management function was received is passed to the LIO core instead of passing 0.

Hello Himanshu and Quinn,

This kind of whitespace changes makes the code harder to read and is not useful in
any way. Please remove all whitespace changes from this patch.

Thanks,

Bart.

Hello Himanshu and Quinn,

Renaming internal variables is fine but renaming module parameters is not
acceptable. Please don't do this.

Hello Himanshu and Quinn,

Please drop this patch. If a command has already been submitted to the LIO
core and an ABTS is received then the LIO core should be requested to perform
the abort. This patch changes the behavior of the qla2xxx target driver such
that the LIO core is not informed at all if abort_cmd_for_tag() finds the
command that has to be aborted in one of the command lists maintained by the
qla2xxx driver. That can lead to the presence of overlapping writes in the
command set on the target system and hence to data corruption. Please note
that I had proposed a better approach on the target-devel mailing list and
that I'm still waiting for someone from Cavium to review these patches:
* [PATCH v6 09/33] target: Make it possible to specify I_T nexus for SCSI
  abort (http://www.spinics.net/lists/target-devel/msg14534.html).
* [PATCH v6 10/33] tcm_qla2xxx: Let the target core look up the LUN of the
  aborted cmd (http://www.spinics.net/lists/target-devel/msg14563.html).

Bart.

This analysis is wrong.

The three lists abort_cmd_for_tag() walks from __qlt_24xx_handle_abts()
are used to track descriptors only before __qlt_do_work() is reached,
and before a descriptor is submitted into tcm_qla2xxx code.

Or rather, the three lists in abort_cmd_for_tag() only contain
qla_tgt_cmd or qla_tgt_sess_op descriptors that have not yet reached
qla_tgt_func_tmpl->handle_cmd() code.

Both qlt_do_work() and qlt_create_sess_from_atio() drop their respective
descriptors from ->cmd_list before dispatching into tcm_qla2xxx ->
target-core, which means there is no way for a descriptor to be part of
internal lists once __qlt_do_work() is called.

That said, the patch is correct and removes the redundant lookup.

Aside from the typo to hard-code LUN=0 in __qlt_24xx_handle_abts() Bart

As your comment above mentions, there is a known issue in target-core
when queue-full occurs repeatably and a se_cmd descriptor is explicitly
stopped via session shutdown, TMR ABORT_TASK / LUN_RESET or otherwise.

We hit this scenario a while back in iser-target with iw_cxgb hw, which
due to a separate bug was constantly triggering queue-full under load to
uncover this same case.

So I'm still considering the different approaches to address this in
target-core proper, but don't have a problem with merging this as-is as
it won't logically conflict with any of those changes.

We see following NULL pointer access on a faster systems. So far its has been only seen on
couple systems in our env.

we had added module parameter “ ql2xmvasynctoatio” as part of the Improve RSCN handling patch 
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/scsi/qla2xxx?id=41dc529a4602ac737020f423f84686a81de38e6d

At the time when we submitted patch, we were setting bit for all ISPs which is not correct. Only ISP83XX/27XX should be allowed to set this bit. 

Setting this Bit will allow firmware to post ABTS/PUREX/RIDA IOCB’s via ATIO queue only when target/dual mode is operational.

I do not agree that this patch is makes ABTS handling fully robust. It seems
like you have not noticed that the following race can occur with or without
this patch applied: if abort_cmd_for_tag() and qlt_try_to_dequeue_unknown_atios()
are called concurrently, since the latter function calls list_del() after
qlt_send_term_exchange(), abort_cmd_for_tag() can return 1 and thereby trigger
a call to qlt_24xx_send_abts_resp() while qlt_try_to_dequeue_unknown_atios()
calls qlt_send_term_exchange() concurrently. I think an initiator could get
really confused if it receives two responses for the same exchange.

An existing issue that is not addressed by this patch is that if an ABTS is
received after qlt_do_work() has called list_del() and before __qlt_do_work()
triggers a call target_submit_cmd() that a command is not on any list and hence
that abort_cmd_for_tag() won't be able to find it anywhere.

Shouldn't these issues be addressed properly?

Bart.

    I do not agree that this patch is makes ABTS handling fully robust. It seems
    like you have not noticed that the following race can occur with or without
    this patch applied: if abort_cmd_for_tag() and qlt_try_to_dequeue_unknown_atios()
    are called concurrently, since the latter function calls list_del() after
    qlt_send_term_exchange(), abort_cmd_for_tag() can return 1 and thereby trigger
    a call to qlt_24xx_send_abts_resp() while qlt_try_to_dequeue_unknown_atios()
    calls qlt_send_term_exchange() concurrently. 

QT:  “[PATCH 03/25] qla2xxx: Allow ABTS RX, RIDA on ATIOQ for ISP83XX/27XX” attempts to reduce the describe concurrency by moving the IOCB from the RSPQ thread to the ATIOQ thread.  This helps preserve the ordering between SCSI cmd & ABTS.

I think an initiator could get
    really confused if it receives two responses for the same exchange.

QT:  I do see the window you’re describing in the qlt_try_to_dequeue_unknown_atios().  Will have to follow up with another patch.   This patch is not meant for this window you’ve just identify.

    
    An existing issue that is not addressed by this patch is that if an ABTS is
    received after qlt_do_work() has called list_del() and before __qlt_do_work()
    triggers a call target_submit_cmd() that a command is not on any list and hence
    that abort_cmd_for_tag() won't be able to find it anywhere.

QT:  Actually, we’re covered in this case.    There 2 responds for 2 IOCB/transactions.  1) The  abort_cmd_for_tag() finds the SCSI command on the qla_cmd_list and turns on the abort flag while cmd is in work queue & before __qlt_do_work is called.  When __qlt_do_work is call and sees the aborted flag, the thread will terminate/cleanup the SCSI command and will not submit to TCM.

As for the ABTS, the abort_cmd_for_tag() returns 1 after finding the command will trigger an ABTS respond.  

static void __qlt_do_work(struct qla_tgt_cmd *cmd)
{
       if (cmd->aborted) {
                ql_dbg(ql_dbg_tgt_mgt, vha, 0xf082,
                    "cmd with tag %u is aborted\n",
                    cmd->atio.u.isp24.exchange_addr);
                goto out_term;
        }
}

    Shouldn't these issues be addressed properly?

QT: Will follow up with another patch for the new problem. thanks for the extra eyes.
    
    Bart.

In that case, please tag the fixes patches with:

Patches 1-10 look innocuous enough that they should be OK. Patch
descriptions could be better, though. Please repost these ASAP.

11-25 are less critical. We still have a couple of weeks left for "big
things" in the 4.13 submission window.
