Hi Martin,
The patch series contains fixes for qla2xxx and solves two visible
issues:
- Target port in N2N topology doesn't perform login if it has higher
WWPN than initiator
- ABORT TASK TMF leads to crash if it's received shortly after ACL of
an initiator is deleted and there's active I/O from the initiator
It also contains reliability improvements and cleanups.
Unfortunately, there's still an issue the latest patch. The discard
works but ELS IOCB for LOGO is likely built incorrectly by
qla24xx_els_dcmd_iocb(). The issue can also be exposed when "1" is
written to fc_host/hostN/device/issue_logo file with logging turned on.
Changes since v1 (https://patchwork.kernel.org/cover/11141979/):
- Fixes target port in N2N mode were added (patches 5-11);
- Target port makes explicit LOGO on session teardown in the patch made
by Quinn. Together with patch 1, it helps to immediately turn
fc_remote_port to the Blocked stated on client side and avoids visibly
stuck session;
- The last three patches address violation of FCP specification with
regards to handling of ABTS-LS from ports that are not currently
logged in.
Thank you,
Roman

If ABTS cannot be completed in target mode, the driver attempts to free
related management command and crashes:

The crash can be triggered by ACL deletion when there's active I/O.
During ACL deletion, qla2xxx performs implicit LOGO that's invisible for
the initiator. Only the driver and firmware are aware of the logout.
Therefore the initiator continues to send SCSI commands and the target
always responds with SAM STATUS BUSY as it can't find the session.
The command times out after a while and initiator invokes ABORT TASK TMF
for the command. The TMF is mapped to ABTS-LS in FCP. The target can't
find session for S_ID originating ABTS-LS so it never allocates mcmd.
And since N_Port handle was deleted after LOGO, it is no longer valid
and ABTS Response IOCB is returned from firmware with status 31. Then
free_mcmd is invoked on NULL pointer and the kernel crashes.

Target creation triggers a new BUG_ON introduced in in 4d43d395fed12

The BUG_ON reveals an attempt to flush free_work in qla24xx_do_nack_work

Target creation triggers a new BUG_ON introduced in in 4d43d395fed12
("workqueue: Try to catch flush_work() without INIT_WORK().").
The BUG_ON reveals an attempt to flush free_work in qla24xx_do_nack_work
before it's initialized in qlt_unreg_sess:

del_work is already initialized inside qla2x00_alloc_fcport, there's no
need to overwrite it. Indeed, it might prevent complete traversal of
workqueue list.

When a port sends PLOGI, discovery state should be changed to login
pending, otherwise RELOGIN_NEEDED bit is set in
qla24xx_handle_plogi_done_event(). RELOGIN_NEEDED triggers another
PLOGI, and it never goes out of the loop until login timer expires.

According to FC-LS-3 (Fibre Channel Link Services) 6.3.2.4
"N_Port Login - No Fabric present", if both parties in the point-to-point
connection know N_Port_Names of each other, Nx_Port with the highest
N_Port_name shall transmit PLOGI. The specification sets no restrictions
on the port role that should send PLOGI.
However, FCP-4 (Fibre Channel Protocol for SCSI, Fourth Version) 6.2
"Overview of Process Login and Process Logout", instructs that in
point-to-point topology, initiator shall send explicit PRLI ELS.
The change fixes stuck P2P login, when target WWPN is higher than
initiator WWPN.

MBA_PORT_UPDATE generates duplicate log lines in target mode because
qlt_async_event is called twice. Drop the calls within the case as
the function will be called right after the switch statement.

qla2x00_configure_local_loop initializes PLOGI payload for PLOGI ELS
using Get Parameters mailbox command.
In the case when the driver is running in target mode, the topology is
N2N and the target port has higher WWPN, LOCAL_LOOP_UPDATE bit is
cleared too early and PLOGI payload is not initialized by the Get
Parameters command. That causes a failure of ELS IOCB carrying the
PLOGI with 0x15 aka Data Underrun error.
LOCAL_LOOP_UPDATE has to be set to initialize PLOGI payload.

qlt_handle_login schedules session for deletion even if a login is in
progress. That causes login bouncing, i.e. a few logins are made before
it settles down.
Complete the first login by sending Notify Acknowledge IOCB via
qlt_plogi_ack_unref if the session is pending login completion.

qla2x00_configure_local_loop sets RELOGIN_NEEDED bit and calls
qla24xx_fcport_handle_login to perform the login. This bit triggers
a wake up of DPC later after a successful login.
The deferred call is not needed if login succeeds, and it's set in
qla24xx_fcport_handle_login in case of errors, hence it should be safe
to drop.

PORT UPDATE asynchronous event is generated on the host that issues PLOGI
ELS (in the case of higher WWPN). In that case, the event shouldn't be
handled as it sets unwanted DPC flags (i.e. LOOP_RESYNC_NEEDED) that
trigger link flap.
Ignore the event if the host has higher WWPN, but handle otherwise.

* [PATCH v2 11/15] scsi: qla2xxx: Ignore PORT UPDATE after N2N PLOGI

PORT UPDATE asynchronous event is generated on the host that issues PLOGI
ELS (in the case of higher WWPN). In that case, the event shouldn't be
handled as it sets unwanted DPC flags (i.e. LOOP_RESYNC_NEEDED) that
trigger link flap.
Ignore the event if the host has higher WWPN, but handle otherwise.

Target makes implicit LOGO on session teardown. LOGO ELS is not send on
the wire and initiator is not aware that target no longer wants talking
to it. Initiator keeps sending I/O requests, target responds with
BA_RJT, they time out and then initiator sends ABORT TASK (ABTS-LS).
Current behaviour incurs unneeded I/O timeout and can be fixed by making
explicit LOGO on session deletion.

qla24xx_els_dcmd_iocb() performs LOGO and might be invoked in contexts where it
is prohibited to sleep. The new wait parameter provides a way to use the
function in such context, similarly to qla24xx_els_dcmd2_iocb().

Fibre Channel Protocol for SCSI, Fourth Version (FCP-4) 12.3.3, "Target
FCP_Port response to Exchange termination" states:
When an ABTS-LS is received at the target FCP_Port, it shall abort the
designated Exchange and return one of the following responses:
a) the target FCP_Port shall discard the ABTS-LS and transmit a LOGO ELS if
the Nx_Port issuing the ABTS-LS is not currently logged in (i.e., no
N_Port Login exists);
However, current implementation tries to send a real BA_RJT in response to ABTS
from logged-out ports. The oparation fails because N_Port handle was freed
shortly after logout and ABTS Recieved IOCB contains 0xFFFF N_Port handle.
Existing implementation doesn't send LOGO at all.
The correct way to discard ABTS-LS frame when N_Port handle wasn't found is to
set Terminate ABTS Exchange bit in control flags of ABTS Response IOCB.
LOGO is sent after that.
To avoid a deadlock in qla2x00_start_sp(), hardware_lock should be released.
The unlocking should be safe because ABTS Recieved IOCB is not needed after
s_id is saved on the stack and qlt_24xx_send_abts_resp() is invoked.

According to FC-LS-3 (Fibre Channel Link Services) 6.3.2.4 "N_Port Login - No Fabric present", if both parties in the point-to-point connection know N_Port_Names of each other, Nx_Port with the highest N_Port_name shall transmit PLOGI. The specification sets no restrictions on the port role that should send PLOGI.
However, FCP-4 (Fibre Channel Protocol for SCSI, Fourth Version) 6.2 "Overview of Process Login and Process Logout", instructs that in point-to-point topology, initiator shall send explicit PRLI ELS.
The change fixes stuck P2P login, when target WWPN is higher than initiator WWPN.

qla2x00_configure_local_loop initializes PLOGI payload for PLOGI ELS using Get Parameters mailbox command.
In the case when the driver is running in target mode, the topology is N2N and the target port has higher WWPN, LOCAL_LOOP_UPDATE bit is cleared too early and PLOGI payload is not initialized by the Get Parameters command. That causes a failure of ELS IOCB carrying the PLOGI with 0x15 aka Data Underrun error.
LOCAL_LOOP_UPDATE has to be set to initialize PLOGI payload.

Subject: [EXT] [PATCH v2 09/15] scsi: qla2xxx: Send Notify ACK after N2N PLOGI
External Email
----------------------------------------------------------------------
qlt_handle_login schedules session for deletion even if a login is in progress. That causes login bouncing, i.e. a few logins are made before it settles down.
Complete the first login by sending Notify Acknowledge IOCB via qlt_plogi_ack_unref if the session is pending login completion.

----------------------------------------------------------------------
qla2x00_configure_local_loop sets RELOGIN_NEEDED bit and calls qla24xx_fcport_handle_login to perform the login. This bit triggers a wake up of DPC later after a successful login.
The deferred call is not needed if login succeeds, and it's set in qla24xx_fcport_handle_login in case of errors, hence it should be safe to drop.

According to FC-LS-3 (Fibre Channel Link Services) 6.3.2.4 "N_Port Login - No Fabric present", if both parties in the point-to-point connection know N_Port_Names of each other, Nx_Port with the highest N_Port_name shall transmit PLOGI. The specification sets no restrictions on the port role that should send PLOGI.
However, FCP-4 (Fibre Channel Protocol for SCSI, Fourth Version) 6.2 "Overview of Process Login and Process Logout", instructs that in point-to-point topology, initiator shall send explicit PRLI ELS.
The change fixes stuck P2P login, when target WWPN is higher than initiator WWPN.

qla2x00_configure_local_loop initializes PLOGI payload for PLOGI ELS
using Get Parameters mailbox command.
In the case when the driver is running in target mode, the topology is
N2N and the target port has higher WWPN, LOCAL_LOOP_UPDATE bit is
cleared too early and PLOGI payload is not initialized by the Get
Parameters command. That causes a failure of ELS IOCB carrying the
PLOGI with 0x15 aka Data Underrun error.
LOCAL_LOOP_UPDATE has to be set to initialize PLOGI payload.

qlt_handle_login schedules session for deletion even if a login is in
progress. That causes login bouncing, i.e. a few logins are made before
it settles down.
Complete the first login by sending Notify Acknowledge IOCB via
qlt_plogi_ack_unref if the session is pending login completion.

qla24xx_els_dcmd_iocb() performs LOGO and might be invoked in contexts where it is prohibited to sleep. The new wait parameter provides a way to use the function in such context, similarly to qla24xx_els_dcmd2_iocb().

Would this not result in a memory leak in the 'else' path - skiping sp->free(sp)?

External Email
----------------------------------------------------------------------
qla24xx_els_dcmd_iocb() performs LOGO and might be invoked in contexts where it is prohibited to sleep. The new wait parameter provides a way to use the function in such context, similarly to qla24xx_els_dcmd2_iocb().

Would this not result in a memory leak in the 'else' path - skipping sp->free(sp)?
QT: Good point. This mean the patch is missing qla2x00_els_dcmd_sp_done checking for SRB_WAKEUP_ON_COMP to wake up or free the sp.

External Email
----------------------------------------------------------------------
qla24xx_els_dcmd_iocb() performs LOGO and might be invoked in contexts where it is prohibited to sleep. The new wait parameter provides a way to use the function in such context, similarly to qla24xx_els_dcmd2_iocb().

Well, I investigated two distinct crash-at-rmmod cases, and one was
already fixed by the earlier commit f45bca8c5052 ("scsi: qla2xxx: Fix
double scsi_done for abort path"), whereas the other is still present,
even after applying this series.
Not to say the series is bad - we just shouldn't raise expectations
too high.

Well, I investigated two distinct crash-at-rmmod cases, and one was
already fixed by the earlier commit f45bca8c5052 ("scsi: qla2xxx: Fix

even after applying this series.
Not to say the series is bad - we just shouldn't raise expectations
too high.

Hi Martin,
This patch series only fixes a crash when there's active I/O and ACL of
the initiator is getting deleted. The issue can be reproduced quite
easily:
1. Configure a target with 1 LUN and 1 ACL (and 1 Mapped LUN inside)
2. Run I/O from initiator
3. Delete ACL while running the I/O
The crash happens ~30s after the ACL is deleted when the initiator
starts sending ABORT TASK TMF to abort timed out I/O. It might happen at
rmmod time but that's just coincidence of ABORT TASK being processed. It
might not happen if a rig shuts off in less than 30 seconds.
Thanks,
Roman

Hi Mark,
Good catch, it definetely will be a leak. I had this on mind but forgot
while rushing to post v2. I'll add proper cleanup in v3.
Thank you,
