Current lpfc bsg implementation allows a maximum fw read object size of
30KB. Implementation and support for read object mailbox commands for fw
objects larger than 30KB are now required for proprietary applications.
Thus, update the lpfc_sli_config_emb0_subsys structure and its associated
submission and completion paths to accommodate for an alternative form of
read object command that supports large fw objects.

In attempt to reduce the amount of unnecessary ndlp->lock acquisitions in
the lpfc driver, change save_flags into an unsigned long bitmask and use
clear_bit/test_bit bitwise atomic APIs instead of reliance on ndlp->lock
for synchronization.

When a LS_RJT is received with reason explanation authentication required,
current driver logic is to retry the PLOGI up to 48 times. In the worse
case scenario, 48 retries can take longer than dev_loss_tmo and if there is
an RSCN received indicating an authentication requirement change, the
driver may miss processing it. Fix by adding logic to specifically handle
reason explanation authentication required and set the max retry count to 8
times.

In lpfc_check_adisc, remove the requirement that the ndlp object must have
been RPI registered. Whether or not the ndlp is RPI registered is
unrelated to verifying that the received ADISC is intended for that ndlp
rport object.
After ADISC receipt, there's no need to put the ndlp state into NPR. Let
the cmpl routines from the actions taken earlier in ADISC handling set the
proper ndlp state.
Also, refactor when a RESUME_RPI mailbox command should be sent. It should
only be sent if the RPI registered flag is set.

Remove the NLP_TARGET_REMOVE flag as its usage is obsolete. The current
framework is to rely on the lpfc_dev_loss_tmo_callbk from upper layer to
notify final ndlp kref release. There's no need to specifically set
NLP_EVT_DEVICE_RM when a LOGO completes. The dev_loss_tmo_callbk is
responsible for the final kref put.

The only difference between the .sdev_configure() and .slave_configure()
methods is that the former accepts an additional 'limits' argument.
Convert all SCSI drivers that define a .slave_configure() method to
.sdev_configure(). This patch prepares for removing the
.slave_configure() method. No functionality has been changed.

Rename .slave_alloc() into .sdev_init() and .slave_destroy() into
.sdev_destroy(). The new names make it clear that these are actions on
SCSI devices. Make this change in the SCSI core, SCSI drivers and also
in the ATA drivers. No functionality has been changed.
This patch has been created as follows:
* Change the text "slave_alloc" into "sdev_init" in all source files
except those in drivers/net/ and Documentation/.
* Change the text "slave_destroy" into "sdev_destroy" in all source
files except those in drivers/net/ and Documentation/.
* Rename lpfc_no_slave() into lpfc_no_sdev().
* Manually adjust whitespace where necessary to restore vertical
alignment (dc395x driver and include/linux/libata.h).

An RPI is tightly bound to an NDLP structure and is freed only upon
release of an NDLP object. As such, there should be no logic that frees

Current dev_loss_tmo handling checks whether there has been a previous
call to unregister with SCSI transport. If so, the NDLP kref count is
decremented a second time in dev_loss_tmo as the final kref release.
However, this can sometimes result in a reference count underflow if
there is also a race to unregister with NVMe transport as well. Add a
check for NVMe transport registration before decrementing the final
kref. If NVMe transport is still registered, then the NVMe transport
unregistration is designated as the final kref decrement.

The lpfc_cmpl_ct_disc_fdmi() routine has incorrect logic that treats an
FDMI completion with error LOCAL_REJECT/SLI_ABORTED as a success status.
Under the erroneous assumption of successful completion, the routine
proceeds to issue follow up FDMI commands, which may never complete if
the HBA is in an errata state as indicated by the errored completion
status. Fix by freeing FDMI cmd resources and early return when the
LPFC_SLI_ACTIVE flag is not set and a LOCAL_REJECT/SLI_ABORTED or
SLI_DOWN status is received.

During firmware errata events, the lpfc_els_flush_cmd() routine is
responsible for the clean up of outstanding ELS and CT command
submissions. Thus, move the LPFC_SLI_ACTIVE flag check into the txcmplq
list walk and mark a piocb object for canceling if determined the HBA is
not active. Clean up should be regardless of application or driver
layer origin.

During initialization, the driver allocates wq->pring in lpfc_wq_create
and lpfc_sli4_queue_unset() is the only place where kfree(wq->pring) is
called.
There is a possible memory leak in lpfc_sli_brdrestart_s4() (restart)
and lpfc_pci_remove_one_s4() (rmmod) paths because there are no calls to
lpfc_sli4_queue_unset() to kfree() the wq->pring.
Fix by inserting a call to lpfc_sli4_queue_unset() in
lpfc_sli_brdrestart_s4() and lpfc_sli4_hba_unset() routines. Also, add
a check for the SLI_ACTIVE flag before issuing the Q_DESTROY mailbox
command. If not set, then the mailbox command will obviously fail. In
such cases, skip issuing the mailbox command and only execute the driver
resource clean up portions of the lpfc_*q_destroy routines.

Should an rport remain in the NOTPRESENT state it is possible that
stgt_delete_work is scheduled after dev_loss_tmo_callbk. In such cases,
dev_loss_tmo_callbk would have cleaned up the NDLP object resulting in
stale ndlp pointers in lpfc_terminate_rport_io().
Check for the DEVLOSS_CALLBK_DONE flag to know if dev_loss_tmo_callbk
has been called. This is a more reliable way to avoid dereferencing
stale NDLP pointers.

As such, the loopback test path is updated to accommodate the extra

Changes include filling in APPID and WQES bit fields for XMIT_SEQUENCE64

data matches what is sent, and increasing ELS WQ size to accommodate the

Revise certain log messages marked as KERN_ERR LOG_TRACE_EVENT to
KERN_WARNING and use the lpfc_vlog_msg() macro to still log the event. The
benefit is that events of interest are still logged and the entire trace
buffer is not dumped with extraneous logging information when using default
lpfc_log_verbose driver parameter settings.
Also, delete the keyword "fail" from such log messages as they aren't
really causes for concern. The log messages are more for warnings to a SAN
admin about SAN activity.

With a FLOGI outstanding and loss of physical link connection to the fabric
for the duration of dev_loss_tmo, there is a fabric ndlp kref imbalance
that decrements the kref and sets the NLP_IN_RECOV_POST_DEV_LOSS flag at
the same time.
The issue is that when the FLOGI completion routine executes, the fabric
ndlp could already be freed because of the final kref put from the
dev_loss_tmo handler. Fix by early returning before the ndlp kref put if
the ndlp is deemed a candidate for NLP_IN_RECOV_POST_DEV_LOSS in the FLOGI
completion routine.

firmware during reset of the adapter. The phba link_state conditional
check is currently a strict == LPFC_LINK_DOWN, which does not cover
initialization states before reaching the LPFC_LINK_UP state.
Update the phba->link_state conditional to < LPFC_LINK_UP so that all
initialization states are covered before allowing sending CMF_SYNC_WQE.
Update taking of the hbalock to be during this link_state check as well.

During HBA stress testing, a spam of received PLOGIs exposes a resource
recovery bug causing leakage of lpfc_sqlq entries from the global
phba->sli4_hba.lpfc_els_sgl_list.
The issue is in lpfc_els_flush_cmd(), where the driver attempts to recover
outstanding ELS sgls when walking the txcmplq. Only CMD_ELS_REQUEST64_CRs
and CMD_GEN_REQUEST64_CRs are added to the abort and cancel lists. A check
for CMD_XMIT_ELS_RSP64_WQE is missing in order to recover LS_ACC usages of
the phba->sli4_hba.lpfc_els_sgl_list too.
Fix by adding CMD_XMIT_ELS_RSP64_WQE as part of the txcmplq walk when
adding WQEs to the abort and cancel list in lpfc_els_flush_cmd(). Also,
update naming convention from CRs to WQEs.

A NULL dev->dma_parms indicates either a bus that is not DMA capable or
grave bug in the implementation of the bus code.
There isn't much the driver can do in terms of error handling for either
case, so just warn and continue as DMA operations will fail anyway.

A kref imbalance occurs when handling an unsolicited PRLO in direct
attached topology.
Rework PRLO rcv handling when in MAPPED state. Save the state that we were
handling a PRLO by setting nlp_last_elscmd to ELS_CMD_PRLO. Then in the
lpfc_cmpl_els_logo_acc() completion routine, manually restart discovery.
By issuing the PLOGI, which nlp_gets, before nlp_put at the end of the
lpfc_cmpl_els_logo_acc() routine, we are saving us from a final nlp_put.
And, we are still allowing the unreg_rpi to happen.

topology
In direct attached topology, certain target vendors that are quick to issue
FLOGI followed by a cable pull for more than dev_loss_tmo may result in a
kref imbalance for the remote port ndlp object.
Add an nlp_get when the defer_flogi_acc flag is set. This is expected to
balance the nlp_put in the defer_flogi_acc clause in the
lpfc_issue_els_flogi() routine. Because we need to retain the ndlp ptr,
reorganize all of the defer_flogi_acc information into one
lpfc_defer_flogi_acc struct.

The vport->vmid_flag is unintentionally cleared twice after an issue_lip
via the lpfc_reinit_vmid routine().
The first call to lpfc_reinit_vmid() is in lpfc_cmpl_els_flogi(). Then
lpfc_cmpl_els_flogi_fabric() calls lpfc_register_new_vport(), which calls
lpfc_cmpl_reg_new_vport() when the mbox command completes and calls
lpfc_reinit_vmid() a second time.
Fix by moving the vmid_flag clear outside of the lpfc_reinit_vmid() routine
so that vmid_flag is only cleared once upon FLOGI completion.

When the HBA is undergoing a reset or is handling an errata event, NULL ptr
dereference crashes may occur in routines such as
lpfc_sli_flush_io_rings(), lpfc_dev_loss_tmo_callbk(), or
lpfc_abort_handler().
Add NULL ptr checks before dereferencing hdwq pointers that may have been
freed due to operations colliding with a reset or errata event handler.

During diagnostics, it has been determined that the 0115 log message for
receipt of unknown ELS cmds does not benefit from trace buffer dumps. The
trace buffer dump floods the console with unnecessary information, and the
singular LOG_ELS flag has proven more beneficial in debugging efforts when
dealing with unknown ELS cmds.
