This patch shortens every init_timer in lpfc module followed by function
and data assignment using setup_timer. This is purely cleanup patch, it
does not add new functionality nor remove any existing functionality.
An init_timer call in this form:
init_timer(&vport->fc_disctmo);
vport->fc_disctmo.function = lpfc_disc_timeout;
vport->fc_disctmo.data = vport;
is shortened to:
setup_timer(&vport->fc_disctmo, lpfc_disc_timeout, vport);
It increases readability and reduces chances of mistakes done by
developers.

NVME Initiator: Base modifications
This patch adds base modifications for NVME initiator support.
The base modifications consist of:
- Formal split of SLI3 rings from SLI-4 WQs (sometimes referred to as
rings as well) as implementation now widely varies between the two.
- Addition of configuration modes:
SCSI initiator only; NVME initiator only; NVME target only; and
SCSI and NVME initiator.
The configuration mode drives overall adapter configuration,
offloads enabled, and resource splits.
NVME support is only available on SLI-4 devices and newer fw.
- Implements the following based on configuration mode:
- Exchange resources are split by protocol; Obviously, if only
1 mode, then no split occurs. Default is 50/50. module attribute
allows tuning.
- Pools and config parameters are separated per-protocol
- Each protocol has it's own set of queues, but share interrupt
vectors.
SCSI:
SLI3 devices have few queues and the original style of queue
allocation remains.
SLI4 devices piggy back on an "io-channel" concept that
eventually needs to merge with scsi-mq/blk-mq support (it is
underway). For now, the paradigm continues as it existed
prior. io channel allocates N msix and N WQs (N=4 default)
and either round robins or uses cpu # modulo N for scheduling.
A bunch of module parameters allow the configuration to be
tuned.
NVME (initiator):
Allocates an msix per cpu (or whatever pci_alloc_irq_vectors
gets)
Allocates a WQ per cpu, and maps the WQs to msix on a WQ #
modulo msix vector count basis.
Module parameters exist to cap/control the config if desired.
- Each protocol has its own buffer and dma pools.
I apologize for the size of the patch.

Instead define the timeout behavior purely based on the host_template
eh_timed_out method and wire up the existing transport implementations
in the host templates. This also clears up the confusion that the
transport template method overrides the host template one, so some
drivers have to re-override the transport template one.

The BUG_ON() recently introduced in lpfc_sli_ringtxcmpl_put() is hit in
the lpfc_els_abort() > lpfc_sli_issue_abort_iotag() >
lpfc_sli_abort_iotag_issue() function path [similar names], due to
'piocb->vport == NULL':
BUG_ON(!piocb || !piocb->vport);
This happens because lpfc_sli_abort_iotag_issue() doesn't set the
'abtsiocbp->vport' pointer -- but this is not the problem.
Previously, lpfc_sli_ringtxcmpl_put() accessed 'piocb->vport' only if
'piocb->iocb.ulpCommand' is neither CMD_ABORT_XRI_CN nor
CMD_CLOSE_XRI_CN, which are the only possible values for
lpfc_sli_abort_iotag_issue():
lpfc_sli_ringtxcmpl_put():
if ((unlikely(pring->ringno == LPFC_ELS_RING)) &&
(piocb->iocb.ulpCommand != CMD_ABORT_XRI_CN) &&
(piocb->iocb.ulpCommand != CMD_CLOSE_XRI_CN) &&
(!(piocb->vport->load_flag & FC_UNLOADING)))
lpfc_sli_abort_iotag_issue():
if (phba->link_state >= LPFC_LINK_UP)
iabt->ulpCommand = CMD_ABORT_XRI_CN;
else
iabt->ulpCommand = CMD_CLOSE_XRI_CN;
So, this function path would not have hit this possible NULL pointer
dereference before.
In order to fix this regression, move the second part of the BUG_ON()
check prior to the pointer dereference that it does check for.
For reference, this is the stack trace observed. The problem happened
because an unsolicited event was received - a PLOGI was received after
our PLOGI was issued but not yet complete, so the discovery state
machine goes on to sw-abort our PLOGI.

'size_t' is always the same width as 'long' in the kernel, but the
compiler doesn't know that. The %z modifier is what the standard expects

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static. So this
patch marks these functions with 'static'.

When building with -Wextra, we get a lot of warnings for the lpfc driver
concerning expressions that are always true, starting with:
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_enable_npiv_init':
drivers/scsi/lpfc/lpfc_attr.c:2786:77: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_enable_rrq_init':
drivers/scsi/lpfc/lpfc_attr.c:2802:76: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_suppress_link_up_init':
drivers/scsi/lpfc/lpfc_attr.c:2812:2050: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_log_verbose_init':
drivers/scsi/lpfc/lpfc_attr.c:3064:1930: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
The code works as intended, but it would be nice to shut up the warning
so we don't clutter up build logs with this. Using a separate inline
function for it makes it clear to the compiler that the comparison is
necessary in the caller but still lets it do the constant-folding.
