[ Upstream commit f5779b529240b715f0e358489ad0ed933bf77c97 ]
Because file_name and phba->ModelName are both declared a size 80 bytes,
the extra ".grp" file extension could cause an overflow into file_name.
Define a ELX_FW_NAME_SIZE macro with value 84. 84 incorporates the 4 extra
characters from ".grp". file_name is changed to be declared as a char and
initialized to zeros i.e. null chars.

[ Upstream commit c6087b82a9146826564a55c5ca0164cac40348f5 ]
A static code analysis tool flagged the possibility of buffer overflow when
using copy_from_user() for a debugfs entry.
Currently, it is possible that copy_from_user() copies more bytes than what
would fit in the mybuf char array. Add a min() restriction check between
sizeof(mybuf) - 1 and nbytes passed from the userspace buffer to protect
against buffer overflow.

[ Upstream commit 91a0c0c1413239d0548b5aac4c82f38f6d53a91e ]
When if_type equals zero and pci_resource_start(pdev, PCI_64BIT_BAR4)
returns false, drbl_regs_memmap_p is not remapped. This passes a NULL
pointer to iounmap(), which can trigger a WARN() on certain arches.
When if_type equals six and pci_resource_start(pdev, PCI_64BIT_BAR4)
returns true, drbl_regs_memmap_p may has been remapped and
ctrl_regs_memmap_p is not remapped. This is a resource leak and passes a
NULL pointer to iounmap().
To fix these issues, we need to add null checks before iounmap(), and
change some goto labels.

[ Upstream commit 2850b23e9f9ae3696e472d2883ea1b43aafa884e ]
If the &epd_pool->list is empty when executing
lpfc_get_io_buf_from_expedite_pool() the function would return an invalid
pointer. Even in the case if the list is guaranteed to be populated, the
iterator variable should not be used after the loop to be more robust for
future changes.
Linus proposed to avoid any use of the list iterator variable after the
loop, in the attempt to move the list iterator variable declaration into
the macro to avoid any potential misuse after the loop [1].

[ Upstream commit 336d63615466b4c06b9401c987813fd19bdde39b ]
After issuing a LIP, a specific target vendor does not ACC the FLOGI that
lpfc sends. However, it does send its own FLOGI that lpfc ACCs. The
target then establishes the port IDs by sending a PLOGI. lpfc PLOGI_ACCs
and starts the RPI registration for DID 0x000001. The target then sends a
LOGO to the fabric DID. lpfc is currently treating the LOGO from the
fabric DID as a link down and cleans up all the ndlps. The ndlp for DID
0x000001 is put back into NPR and discovery stops, leaving the port in
stuck in bypassed mode.
Change lpfc behavior such that if a LOGO is received for the fabric DID in
PT2PT topology skip the lpfc_linkdown_port() routine and just move the
fabric DID back to NPR.

[ Upstream commit df0101197c4d9596682901631f3ee193ed354873 ]
When recovering from a pci-parity error the driver is failing to re-create
queues, causing recovery to fail. Looking deeper, it was found that the
interrupt vector count allocated on the recovery was fewer than the vectors
originally allocated. This disparity resulted in CPU map entries with stale
information. When the driver tries to re-create the queues, it attempts to
use the stale information which indicates an eq/interrupt vector that was
no longer created.
Fix by clearng the cpup map array before enabling and requesting the IRQs
in the lpfc_sli_reset_slot_s4 routine().

commit 7f4c5a26f735dea4bbc0eb8eb9da99cda95a8563 upstream.
When connected point to point, the driver does not know the FC4's supported
by the other end. In Fabrics, it can query the nameserver. Thus the driver
must send PRLIs for the FC4s it supports and enable support based on the
acc(ept) or rej(ect) of the respective FC4 PRLI. Currently the driver
supports SCSI and NVMe PRLIs.
Unfortunately, although the behavior is per standard, many devices have
come to expect only SCSI PRLIs. In this particular example, the NVMe PRLI
is properly RJT'd but the target decided that it must LOGO after seeing the
unexpected NVMe PRLI. The LOGO causes the sequence to restart and login is
now in an infinite failure loop.
Fix the problem by having the driver, on a pt2pt link, remember NVMe PRLI
accept or reject status across logout as long as the link stays "up". When
retrying login, if the prior NVMe PRLI was rejected, it will not be sent on
the next login.

commit efe1dc571a5b808baa26682eef16561be2e356fd upstream.
Contention for the mailbox interface may occur during driver initialization
(immediately after a function reset), between mailbox commands initiated
via ioctl (bsg) and those driver requested by the driver.
After setting SLI_ACTIVE flag for a port, there is a window in which the
driver will allow an ioctl to be initiated while the adapter is
initializing and issuing mailbox commands via polling. The polling logic
then gets confused.
Correct by having thread setting SLI_ACTIVE spot an active mailbox command
and allow it complete before proceeding.

commit 5852ed2a6a39c862c8a3fdf646e1f4e01b91d710 upstream.
Messages around firmware download were incorrectly tagged as being related
to discovery trace events. Thus, firmware download status ended up dumping
the trace log as well as the firmware update message. As there were a
couple of log messages in this state, the trace log was dumped multiple
times.
Resolve this by converting from trace events to SLI events.

commit c80b27cfd93ba9f5161383f798414609e84729f3 upstream.
The driver is initiating NVMe PRLIs to determine device NVMe support. This
should not be occurring if CONFIG_NVME_FC support is disabled.
Correct this by changing the default value for FC4 support. Currently it
defaults to FCP and NVMe. With change, when NVME_FC support is not enabled
in the kernel, the default value is just FCP.

[ Upstream commit 99154581b05c8fb22607afb7c3d66c1bace6aa5d ]
When parsing the txq list in lpfc_drain_txq(), the driver attempts to pass
the requests to the adapter. If such an attempt fails, a local "fail_msg"
string is set and a log message output. The job is then added to a
completions list for cancellation.
Processing of any further jobs from the txq list continues, but since
"fail_msg" remains set, jobs are added to the completions list regardless
of whether a wqe was passed to the adapter. If successfully added to
txcmplq, jobs are added to both lists resulting in list corruption.
Fix by clearing the fail_msg string after adding a job to the completions
list. This stops the subsequent jobs from being added to the completions
list unless they had an appropriate failure.

[ Upstream commit e30d55137edef47434c40d7570276a0846fe922c ]
An 'unexpected timeout' message may be seen in a point-2-point topology.
The message occurs when a PLOGI is received before the driver is notified
of FLOGI completion. The FLOGI completion failure causes discovery to be
triggered for a second time. The discovery timer is restarted but no new
discovery activity is initiated, thus the timeout message eventually
appears.
In point-2-point, when discovery has progressed before the FLOGI completion
is processed, it is not a failure. Add code to FLOGI completion to detect
that discovery has progressed and exit the FLOGI handling (noop'ing it).

[ Upstream commit e1364711359f3ced054bda9920477c8bf93b74c5 ]
In devloss timer handler and in backend calls to terminate remote port I/O,
there is logic to walk through all active IOCBs and validate them to
potentially trigger an abort request. This logic is causing illegal memory
accesses which leads to a crash. Abort IOCBs, which may be on the list, do
not have an associated lpfc_io_buf struct. The driver is trying to map an
lpfc_io_buf struct on the IOCB and which results in a bogus address thus
the issue.
Fix by skipping over ABORT IOCBs (CLOSE IOCBs are ABORTS that don't send
ABTS) in the IOCB scan logic.

SLI-4 does not contain a PORT_CAPABILITIES mailbox command (only SLI-3
does, and SLI-3 doesn't use it), yet there are SLI-4 code paths that have
code to issue the command. The command will always fail.
Remove the code for the mailbox command and leave only the resulting
"failure path" logic.

[ Upstream commit 304ee43238fed517faa123e034b593905b8679f8 ]
In SLI-4, when performing a mailbox command with MBX_POLL, the driver uses
the BMBX register to send the command rather than the MQ. A flag is set
indicating the BMBX register is active and saves the mailbox job struct
(mboxq) in the mbox_active element of the adapter. The routine then waits
for completion or timeout. The mailbox job struct is not freed by the
routine. In cases of timeout, the adapter will be reset. The
lpfc_sli_mbox_sys_flush() routine will clean up the mbox in preparation for
the reset. It clears the BMBX active flag and marks the job structure as
MBX_NOT_FINISHED. But, it never frees the mboxq job structure. Expectation
in both normal completion and timeout cases is that the issuer of the mbx
command will free the structure. Unfortunately, not all calling paths are
freeing the memory in cases of error.
All calling paths were looked at and updated, if missing, to free the mboxq
memory regardless of completion status.

[ Upstream commit fffd18ec6579c2d9c72b212169259062fe747888 ]
Fix a crash caused by a double put on the node when the driver completed an
ACC for an unsolicted abort on the same node. The second put was executed
by lpfc_nlp_not_used() and is wrong because the completion routine executes
the nlp_put when the iocbq was released. Additionally, the driver is
issuing a LOGO then immediately calls lpfc_nlp_set_state to put the node
into NPR. This call does nothing.
Remove the lpfc_nlp_not_used call and additional set_state in the
completion routine. Remove the lpfc_nlp_set_state post issue_logo. Isn't
necessary.

With the conversion to blk_io_poll for better interrupt latency in normal
cases, it introduced this code path, executed when I/O aborts or logouts
are seen, which attempts to allocate memory for a mailbox command to be
issued. The allocation is GFP_KERNEL, thus it could attempt to sleep.
Fix by creating a work element that performs the event handling for the
remote port. This will have the mailbox commands and other items performed
in the work element, not the irq. A much better method as the "irq" routine
does not stall while performing all this deep handling code.
Ensure that allocation failures are handled and send LOGO on failure.
Additionally, enlarge the mailbox memory pool to reduce the possibility of
additional allocation in this path.

In a prior patch, the READ_SPARAM command was re-ordered to post after
CONFIG_LINK as the driver is expected to update the driver's copy of the
service parameters for the FLOGI payload. If the bb-credit recovery feature
is enabled, this is fine. But on adapters were bb-credit recovery isn't

Fix by restoring the original command order (READ_SPARAM before

support and reissuing READ_SPARAM to obtain the updated service parameters
(effectively adding in the fix command order).

The driver is unable to successfully login with remote device. During pt2pt
login, the driver completes its FLOGI request with the remote device having
WWN precedence. The remote device issues its own (delayed) FLOGI after
accepting the driver's and, upon transmitting the FLOGI, immediately
recognizes it has already processed the driver's FLOGI thus it transitions
to sending a PLOGI before waiting for an ACC to its FLOGI.
In the driver, the FLOGI is received and an ACC sent, followed by the PLOGI
being received and an ACC sent. The issue is that the PLOGI reception
occurs before the response from the adapter from the FLOGI ACC is
received. Processing of the PLOGI sets state flags to perform the REG_RPI
mailbox command and proceed with the rest of discovery on the port. The
same completion routine used by both FLOGI and PLOGI is generic in
nature. One of the things it does is clear flags, and those flags happen to
drive the rest of discovery. So what happened was the PLOGI processing set
the flags, the FLOGI ACC completion cleared them, thus when the PLOGI ACC
completes it doesn't see the flags and stops.
Fix by modifying the generic completion routine to not clear the rest of
discovery flag (NLP_ACC_REGLOGIN) unless the completion is also associated
with performing a mailbox command as part of its handling. For things such
as FLOGI ACC, there isn't a subsequent action to perform with the adapter,
thus there is no mailbox cmd ptr. PLOGI ACC though will perform REG_RPI
upon completion, thus there is a mailbox cmd ptr.

Some systems are reporting the following log message during driver unload
or system shutdown:
ics_rtas_set_affinity: No online cpus in the mask
A prior commit introduced the writing of an empty affinity mask in calls to
irq_set_affinity_hint() when disabling interrupts or when there are no
remaining online CPUs to service an eq interrupt. At least some ppc64
systems are checking whether affinity masks are empty or not.
Do not call irq_set_affinity_hint() with an empty CPU mask.

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.
