Cannot set NVME segment counts to a large number
The existing module parameter lpfc_sg_seg_cnt is used for both
SCSI and NVME.
Limit the module parameter lpfc_sg_seg_cnt to 128 with the
default being 64 for both NVME and NVMET, assuming NVME is enabled in the
driver for that port. The driver will set max_sgl_segments in the
NVME/NVMET template to lpfc_sg_seg_cnt + 1.

When RPI is not available, driver sends WQE with invalid RPI value and
rejected by HBA.
lpfc 0000:82:00.3: 1:3154 BLS ABORT RSP failed, data: x3/xa0320008
and
lpfc :2753 PLOGI failure DID:FFFFFA Status:x3/xa0240008
In this case, driver accesses rpi_ids array out of bounds.
Fix:
Check return value of lpfc_sli4_alloc_rpi(). Do not allocate
lpfc_nodelist entry if RPI is not available.
When RPI is not available, we will get discovery timeouts and
command drops for some of the vports as seen below.
lpfc :0273 Unexpected discovery timeout, vport State x0
lpfc :0230 Unexpected timeout, hba link state x5
lpfc :0111 Dropping received ELS cmd Data: x0 xc90c55 x0

The symptom is that the driver will fail to login to the fabric.
The reason is because it is out of iocb resources.
There is a one to one relationship between MRQs
(receive buffers for NVMET-FC) and iocbs and the default number of
IOCBs was not accounting for the number of MRQs that were being created.
This fix aligns the number of MRQ resources with the total resources so
that it can handle fabric events when needed.
Also the initialization of ctxlock to be on FCP commands, NOT LS commands.
And modified log messages so that the log output can be correlated with
the analyzer trace.

Fix nvme initiator handline when CONFIG_LPFC_NVME_INITIATOR is not enabled.
With update nvme upstream driver sources, loading
the driver with nvme enabled resulting in this Oops.
BUG: unable to handle kernel NULL pointer dereference at 0000000000000018
IP: lpfc_nvme_update_localport+0x23/0xd0 [lpfc]
PGD 0
Oops: 0000 [#1] SMP
CPU: 0 PID: 10256 Comm: lpfc_worker_0 Tainted
Hardware name: ...
task: ffff881028191c40 task.stack: ffff880ffdf00000
RIP: 0010:lpfc_nvme_update_localport+0x23/0xd0 [lpfc]
RSP: 0018:ffff880ffdf03c20 EFLAGS: 00010202
Cause: As the initiator driver completes discovery at different stages,
it call lpfc_nvme_update_localport to hint that the DID and role may have
changed. In the implementation of lpfc_nvme_update_localport, the driver
was not validating the localport or the lport during the execution
of the update_localport routine. With the recent upstream additions to
the driver, the create_localport routine didn't run and so the localport
was NULL causing the page-fault Oops.
Fix: Add the CONFIG_LPFC_NVME_INITIATOR preprocessor inclusions to
lpfc_nvme_update_localport to turn off all routine processing when
the running kernel does not have NVME configured. Add NULL pointer
checks on the localport and lport in lpfc_nvme_update_localport and
dump messages if they are NULL and just exit.
Also one alingment issue fixed.

There are two versions of a structure for queue creation and setup that the
driver shares with FW. The driver was only treating as version 0.
Verify WQ_CREATE with 128B WQEs in V0 and V1.
Code review of another bug showed the driver passing
128B WQEs and 8 pages in WQ CREATE and V0.
Code inspection/instrumentation showed that the driver
uses V0 in WQ_CREATE and if the caller passes queue->entry_size
128B, the driver sets the hdr_version to V1 so all is good.
When I tested the V1 WQ_CREATE, the mailbox failed causing
the driver to unload.

There are couple of different load/unload issues fixed with this patch.
One of the issues was reported by Junichi Nomura, a patch was submitted
by Johannes Thumsrhirn which did fix one of the problems but the fix in
this patch separates the pring free from the queue free and does not set
the parameter passed in to NULL.
issues:
(1) driver could not be unloaded and reloaded without some Oops or
Panic occurring.
(2) The driver was panicking because of a corruption in the Memory
Manager when the iocb list was getting allocated.
Root cause for the memory corruption was a double free of the Work Queue
ring pointer memory - Freed once in the lpfc_sli4_queue_free when the CQ
was destroyed and again in lpfc_sli4_queue_free when the WQ was destroyed.
The pring free and the queue free were separated, the pring free was moved
to the wq destroy routine because it a better fit logically to delete the
ring with the wq.
The checkpatch flagged several alignmenet issues that were also corrected
with this patch.
The mboxq was never initialed correctly before it was used by the driver
this patch corrects that issue.

In this case, the NVME initiator is sending an LS REQ command on an NDLP
that is not MAPPED. The FW rejects it.
The lpfc_nvme_ls_req routine checks for a NULL ndlp pointer
but does not check the NDLP state. This allows the routine
to send an LS IO when the ndlp is disconnected.
Check the ndlp for NULL, actual node, Target and MAPPED
or Initiator and UNMAPPED. This avoids Fabric nodes getting
the Create Association or Create Connection commands. Initiators
are free to Reject either Create.
Also some of the messages numbers in lpfc_nvme_ls_req were changed because
they were already used in other log messages.

During some link event testing it was observed that the

The initiator is claiming the nvme_fc_unregister_remoteport upcall is
not completing the unregister in the time allotted.
[ 2186.151317] lpfc 0000:07:00.0: 0:(0):6169 Unreg nvme wait failed 0
The wait_for_completion_timeout returns 0 when the wait has
been outstanding for the jiffies passed by the caller. In this error
message, the nvme initiator passed value 5 - meaning 5 jiffies -
and this is just wrong.
Calculate 5 seconds in Jiffies and pass that value
from the current jiffies.
Also the log message for the unregister timeout was reduced
because timeout failure is the same as timeout.

This patch actually does quite a few things. When looking to add
controller reset support, the organization modeled after rdma was
very fragmented. rdma duplicates the reset and teardown paths and does
different things to the block layer on the two paths. The code to build
up the controller is also duplicated between the initial creation and
the reset/error recovery paths. So I decided to make this sane.
I reorganized the controller creation and teardown so that there is a
connect path and a disconnect path. Initial creation obviously uses
the connect path. Controller teardown will use the disconnect path,
followed last access code. Controller reset will use the disconnect
path to stop operation, and then the connect path to re-establish
the controller.
Along the way, several things were fixed
- aens were not properly set up. They are allocated differently from
the per-request structure on the blk queues.
- aens were oddly torn down. the prior patch corrected to abort, but
we still need to dma unmap and free relative elements.
- missed a few ref counting points: in aen completion and on i/o's
that fail
- controller initial create failure paths were still confused vs teardown
before converting to ref counting vs after we convert to refcounting.

Add abort support for aens. Commonized the op abort to apply to aen or
real ios (caused some reorg/routine movement). Abort path sets termination
flag in prep for next patch that will be watching i/o abort completion
before proceeding with controller teardown.
Now that we're aborting aens, the "exit" code that simply cleared out
their context no longer applies.
Also clarified how we detect an AEN vs a normal io - by a flag, not
by whether a rq exists or the a rqno is out of range.
Note: saw some interesting cases where if the queues are stopped and
we're waiting for the aborts, the core layer can call the complete_rq
callback for the io. So the io completion synchronizes link side completion
with possible blk layer completion under error.

If the CONFIG_SRCU option is not selected, for example, when building
arch/tile allnoconfig, the following build errors appear:
kernel/rcu/tree.o: In function `srcu_online_cpu':
tree.c:(.text+0x4248): multiple definition of `srcu_online_cpu'
kernel/rcu/srcutree.o:srcutree.c:(.text+0x2120): first defined here

tree.c:(.text+0x4250): multiple definition of `srcu_offline_cpu'
kernel/rcu/srcutree.o:srcutree.c:(.text+0x2160): first defined here
The corresponding .config file shows CONFIG_TREE_SRCU=y, but no sign
of CONFIG_SRCU, which fatally confuses SRCU's #ifdefs, resulting in
the above errors. The reason this occurs is the folowing line in
init/Kconfig's definition for TREE_SRCU:
default y if !TINY_RCU && !CLASSIC_SRCU
If CONFIG_CLASSIC_SRCU=n, as it will be in for allnoconfig, and if
CONFIG_SMP=y, then we will get CONFIG_TREE_SRCU=y but no CONFIG_SRCU,
as seen in the .config file, and which will result in the above errors.
This error did not show up during rcutorture testing because rcutorture
forces CONFIG_SRCU=y, as it must to prevent build errors in rcutorture.c.
This commit therefore conditions TREE_SRCU (and TINY_SRCU, while it is
at it) with SRCU, like this:
default y if SRCU && !TINY_RCU && !CLASSIC_SRCU

Fix this atomic counter and, in order to avoid taking an irq lock on the

Also, in the case that a significant number of blocks become bad in a
