089ea22e37 scsi: lpfc: Abort outstanding ELS cmds when mailbox timeout error is detected
A mailbox timeout error usually indicates something has gone wrong, and a
follow up reset of the HBA is a typical recovery mechanism.  Introduce a
MBX_TMO_ERR flag to detect such cases and have lpfc_els_flush_cmd abort ELS
commands if the MBX_TMO_ERR flag condition was set.  This ensures all of
the registered SGL resources meant for ELS traffic are not leaked after an
HBA reset.

b9951e1cff scsi: lpfc: Change firmware upgrade logging to KERN_NOTICE instead of TRACE_EVENT
A firmware upgrade does not necessitate dumping of phba->dbg_log[] to kmsg
via LOG_TRACE_EVENT.  A simple KERN_NOTICE log message should suffice to
notify the user of successful or unsuccessful firmware upgrade.  As such,
firmware upgrade log messages are updated to use KERN_NOTICE instead of
LOG_TRACE_EVENT.  Additionally, in order to notify the user of reset type
for instantiating newly downloaded firmware, lpfc_log_msg's default
KERN_LEVEL is updated to 5 or KERN_NOTICE.

a7b94c1592 scsi: lpfc: Replace blk_irq_poll intr handler with threaded IRQ
It has been determined that the threaded IRQ API accomplishes effectively
the same performance metrics as blk_irq_poll.  As blk_irq_poll is mostly
scheduled by the softirqd and handled in softirq context, this is not
entirely desired from a Fibre Channel driver context.  A threaded IRQ model
fits cleaner.  This patch replaces the blk_irq_poll logic with threaded
IRQ.

91a0c0c141 scsi: lpfc: Fix ioremap issues in lpfc_sli4_pci_mem_setup()
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.

Bjorn Helgaas <helgaas@kernel.org> says:

Since f26e58bf6f ("PCI/AER: Enable error reporting when AER is native"),

all devices during enumeration.

e891681b1d scsi: lpfc: Drop redundant pci_enable_pcie_error_reporting()
pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since commit f26e58bf6f ("PCI/AER: Enable error reporting when
AER is native"), the PCI core does this for all devices during enumeration,
so the driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

27c2bcf00a scsi: lpfc: Skip waiting for register ready bits when in unrecoverable state
During tolerance tests that force an HBA to become unresponsive, rmmod
hangs resulting in the inability to remove the driver.

The lpfc_pci_remove_one_s4() routine attempts to submit a clean up mailbox
command via the lpfc_sli4_post_sync_mbox() routine, but ends up waiting
forever for a mailbox register to set its ready bit.  Because the HBA is in
an unrecoverable and unresponsive state, the ready bit will never be set.

Create a new routine called lpfc_sli4_unrecoverable_port(), which checks a
port status register's error notification bits.

Use the lpfc_sli4_unrecoverable_port() routine in ready bit check routines
to early return error if port is deemed unrecoverable.

Also, when the lpfc_handle_eratt_s4() handler detects an unrecoverable
state, call the lpfc_sli4_offline_eratt() routine to kick off flushing
outstanding I/O.

Currently, an early return error is thrown from lpfc_read_object() to

8ca09d5fa3 cpumask: fix incorrect cpumask scanning result checks
It turns out that commit 596ff4a09b ("cpumask: re-introduce
constant-sized cpumask optimizations") exposed a number of cases of
drivers not checking the result of "cpumask_next()" and friends
correctly.

The documented correct check for "no more cpus in the cpumask" is to
check for the result being equal or larger than the number of possible
CPU ids, exactly _because_ we've always done those constant-sized
cpumask scans using a widened type before.  So the return value of a
cpumask scan should be checked with

	if (cpu >= nr_cpu_ids)
		...

because the cpumask scan did not necessarily stop exactly *at* that
maximum CPU id.

But a few cases ended up instead using checks like

	if (cpu == nr_cpumask_bits)
		...

which used that internal "widened" number of bits.  And that used to
work pretty much by accident (ok, in this case "by accident" is simply
because it matched the historical internal implementation of the cpumask
scanning, so it was more of a "intentionally using implementation
details rather than an accident").

But the extended constant-sized optimizations then did that internal
implementation differently, and now that code that did things wrong but
matched the old implementation no longer worked at all.

Which then causes subsequent odd problems due to using what ends up
being an invalid CPU ID.

Most of these cases require either unusual hardware or special uses to
hit, but the random.c one triggers quite easily.

All you really need is to have a sufficiently small CONFIG_NR_CPUS value
for the bit scanning optimization to be triggered, but not enough CPUs
to then actually fill that widened cpumask.  At that point, the cpumask
scanning will return the NR_CPUS constant, which is _not_ the same as
nr_cpumask_bits.

This just does the mindless fix with

   sed -i 's/== nr_cpumask_bits/>= nr_cpu_ids/'

to fix the incorrect uses.

The ones in the SCSI lpfc driver in particular could probably be fixed
more cleanly by just removing that repeated pattern entirely, but I am
not emptionally invested enough in that driver to care.

Failure) and 0x9 (Link Reset Protocol Event).

Both attention types are meant to be informational-only type ACQEs with no

0x8 is reported for diagnostic purposes, while 0x9 is posted during a
normal link up transition when activating BB Credit Recovery feature.

As such, modify lpfc_sli4_async_fc_evt() logic to log the attention types

Adapter configurations with limited EQ resources may fail to initialize.

Firmware resources are queried in lpfc_sli4_read_config().  The driver
parameters cfg_irq_chann and cfg_hdw_queue are adjusted from defaults if
constrained by firmware resources.

The minimum resource check includes a special allocation for queues such as

applied to EQ resources.

Reordered WQ|CQ|EQ resource checks to apply the special allocation
adjustment to WQ and CQ resources only.

dc8e483f68 scsi: lpfc: Fix memory leak in lpfc_create_port()
Commit 5e633302ac ("scsi: lpfc: vmid: Add support for VMID in mailbox
command") introduced allocations for the VMID resources in
lpfc_create_port() after the call to scsi_host_alloc(). Upon failure on the
VMID allocations, the new code would branch to the 'out' label, which
returns NULL without unwinding anything, thus skipping the call to
scsi_host_put().

Fix the problem by creating a separate label 'out_free_vmid' to unwind the
VMID resources and make the 'out_put_shost' label call only
scsi_host_put(), as was done before the introduction of allocations for
VMID.

 2. Initialize vlan_id to LPFC_FCOE_NULL_VID.

 3. prg->dist is a 2 bit field. Its value can only be between 0-3.
    Remove redundent check 'if (prg->dist < 4)'.

 4. Fix inconsistent indenting.  Moved logic into helper function
    lpfc_fill_vpd().

    Also, check for return value of pci_irq_vector() and log message in
    case of failure.

 6. Initialize 'ext_cnt' to 0.

 7. Initialize 'ext_size' to 0.

 8. Use alloc_percpu_gfp() with GFP_ATOMIC flag.

 9. 'rc' was not updated when dma_pool_create() fails.  Update 'rc =
     -ENOMEM' when dma_pool_create() fails before calling goto statement.

10. Add check for 'phba->pport' in lpfc_cpuhp_remove().

11. Initialize 'hash_value' to NULL, same like 'aug_chal' variable.

6e5c5d246e scsi: lpfc: Move scsi_host_template outside dynamically allocated/freed phba
On a PCI hotplug capable system, it is possible for scsi_device_put() to
happen after lpfc_pci_remove_one() is called.  As a result, the
sdev->host->hostt->module dereference is for a previously freed memory
location because the phba structure containing the hostt template was
already freed when lpfc_pci_remove_one() returned.

Since the lpfc module is still loaded during power slot disable, all
scsi_host_templates should be declared as part of the global data segment
instead of inside the heap allocated phba structure.  This way the
sdev->host->hostt memory area is always valid as long as the module is
loaded regardless if PCI hotplug dynamically allocates or frees phba
structures.

Move all scsi_host_templates in the phba structure to global variables.
Create a small helper routine to determine appropriate sg_tablesize during
shost allocation.

The kernel test robot reported the following sparse warning:

arch/arm64/include/asm/cmpxchg.h:88:1: sparse: sparse: cast truncates
   bits from constant value (369 becomes 69)

On arm64, atomic_xchg only works on 8-bit byte fields.  Thus, the macro
usage of LPFC_RXMONITOR_TABLE_IN_USE can be unintentionally truncated
leading to all logic involving the LPFC_RXMONITOR_TABLE_IN_USE macro to not
work properly.

Replace the Rx Table atomic_t indexing logic with a new
lpfc_rx_info_monitor structure that holds a circular ring buffer.  For
locking semantics, a spinlock_t is used.

e6f5104145 scsi: lpfc: Alter FPIN stat accounting logic
When configuring CMF management based on signals instead of FPINs, FPIN
alarm and warning statistics are not tracked.

Change the behavior so that FPIN alarms and warnings are always tracked
regardless of the configured mode.

Similar changes are made in the CMF signal stat accounting logic.  Upon
receipt of a signal, only track signaled alarms and warnings. FPIN stats
should not be incremented upon receipt of a signal.

de3ec318fe scsi: lpfc: Rework FDMI initialization after link up
After a link up, it's possible for the switch to change FDMI support (e.g.
FDMI1 vs FDMI2 vs SmartSAN).  If the switch reverts to FDMI1, then the
revert is currently not detected.

Additionally, when NPIV is configured, it's possible the physical port's
RHBA is unprocessed by the switch before reciept of an NPIV port issued
RPRT.  This causes some switches vendors to reject the NPIV's RPRT.

Fix by reinitializing base FDMI mode on link up, and defer FDMI vport RPRT
submission until after confirming physical port's RHBA is completed.

1b6f71f7fc scsi: lpfc: Change FA-PWWN detection methodology
Do not rely on vendor version field of the CSPs to determine if we are in a
FA-PWWN environment. Instead, use the following procedure:

First, during HBA initialization, driver does a READ_CONFIG to determine if
FA-PWWN is configured on the HBA. A LPFC_FAWWPN_CONFIG hba_flag is set
accordingly.

Next, when the link comes up before the driver gets a link up event, the
firmware logs into the fabric with FA-PWWN. If the fabric port does not
support FA-PWWN, the driver will get a Misconfigured FA-WWN async event
before the link up. A LPFC_FAWWPN_FABRIC hba_flag will be set accordingly.

Finally, if the fabric supports FA-PWWN, the firmware will replace its CSPs
WWN with the Fabric Assigned ones. Then after link up, the driver will
retrieve the Fabric Assigned WWN when it does a READ_SPARAM mbox command.

ef47575fd9 scsi: lpfc: Refactor cleanup of mailbox commands
The intention of this patch is to refactor mailbox memory allocation and
cleanup steps in one routine respectively to prevent memory leaks or memory
errors related to mailbox commands.  There are trivial localized fixes as
well.

Provide lpfc_mbox_rsrc_prep() - this routine allocates the dmabuf and the
mbuf associated with it.  It also catches allocation errors and returns
status.

Provide lpfc_mbox_rsrc_cleanup() - this routine verifies a dmabuf exists
and if so releases the associated mbuf and the dmabuf memory.  It then sets
the ctx_buf to NULL and releases the mailbox memory to the mailbox pool.

d51cf5bd92 scsi: lpfc: Fix field overload in lpfc_iocbq data structure
The lpfc_iocbq data structure has void * pointers that are overloaded to be
as many as 8 different data types and the driver translates the void * by
casting.  This patch removes the void * pointers by declaring the specific
types needed by the driver.  It also expands the context_un to include more
seldom used pointer types to save structure bytes.  It also groups the u8
types together to pack the 8 bytes needed.  This work allows the lpfc_iocbq
data structure to be more strongly typed and keeps it from being allocated
from the 512 byte slab.

[mkp: rolled in zeroday fix]

a6de9a2fa0 scsi: lpfc: Fix diagnostic fw logging after a function reset
The lpfc_sli4_ras_setup() routine is only called from the
lpfc_pci_probe_one_s4() routine, which means diagnostic fw logging
initialization only occurs during probing.

Thus, any path involving a reset of the HBA that restarts the state of the
SLI port does not reinitialize diagnostic fw logging.

Move lpfc_sli4_ras_setup() into lpfc_sli4_hba_setup() so that the
LOWLEVEL_SET_DIAG_LOG_OPTIONS mailbox command can be sent after a function
reset.
