scsi: lpfc: Reduce log messages seen after firmware download

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.

scsi: lpfc: Remove NVMe support if kernel has NVME_FC disabled

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.

scsi: ufs: Add checking lifetime attribute for WriteBooster

Because WB performs writes in SLC mode, it is not possible to use
WriteBooster indefinitely. Vendors can set a lifetime limit in the device.
If the lifetime exceeds this limit, the device ican disable the WB feature.

The feature is defined in the "bWriteBoosterBufferLifeTimeEst (IDN = 1E)"
attribute.

With lifetime exceeding the limit value, the current driver continuously
performs the following query:

- Write Flag: WB_ENABLE / DISABLE
- Read attr: Available Buffer Size
- Read attr: Current Buffer Size

This patch recognizes that WriteBooster is no longer supported by the
device, and prevents unnecessary queries.

scsi: pm8001: Fix use-after-free for aborted SSP/STP sas_task

Currently a use-after-free may occur if a sas_task is aborted by the upper
layer before we handle the I/O completion in mpi_ssp_completion() or
mpi_sata_completion().

In this case, the following are the two steps in handling those I/O
completions:

 - Call complete() to inform the upper layer handler of completion of
   the I/O.

 - Release driver resources associated with the sas_task in
   pm8001_ccb_task_free() call.

When complete() is called, the upper layer may free the sas_task. As such,
we should not touch the associated sas_task afterwards, but we do so in the
pm8001_ccb_task_free() call.

Fix by swapping the complete() and pm8001_ccb_task_free() calls ordering.

scsi: core: Reallocate device's budget map on queue depth change

We currently use ->cmd_per_lun as initial queue depth for setting up the
budget_map. Martin Wilck reported that it is common for the queue_depth to
be subsequently updated in slave_configure() based on detected hardware
characteristics.

As a result, for some drivers, the static host template settings for
cmd_per_lun and can_queue won't actually get used in practice. And if the
default values are used to allocate the budget_map, memory may be consumed
unnecessarily.

Fix the issue by reallocating the budget_map after ->slave_configure()
returns. At that time the device queue_depth should accurately reflect what
the hardware needs.

scsi: scsi_debug: Use TASK SET FULL more

When the internal in_use bit array in this driver is full returning
SCSI_MLQUEUE_HOST_BUSY leads to the mid-level reissuing the request which
is unhelpful. Previously TASK SET FULL status was only returned if ALL_TSF
[0x400] is placed in the opts variable (at load time or via sysfs). Now

full. Also set DID_ABORT together with TASK SET FULL so the mid-level gives
up immediately.

Aside: the situations addressed by this patch lead to lockups and
timeouts. They have only been detected when blk_poll() is used. That
mechanism is relatively new in the SCSI subsystem suggesting the mid-level
may need more work in that area.

scsi: scsi_debug: Address races following module load

When scsi_debug is loaded as a module with many (simulated) hosts, targets,
and devices (LUs), modprobe can take a long time to return.  Only a small
amount of this time is spent in the scsi_debug_init(); the rest is other
parts of the kernel reacting to to the appearance of new storage
devices. As soon as scsi_debug_init() has completed the user space may call
'rmmod scsi_debug' and this was found to cause race problems as outlined
here:

    https://bugzilla.kernel.org/show_bug.cgi?id=212337

To reliably generate this race a sysfs parameter called rm_all_hosts was
added and the code was strengthened in this area. The main change was to
make the count of scsi_debug hosts present an atomic.  Then it was found
that the handling of the existing add_host parameter needed the same
strengthening. Further: 'echo -9999 >
/sys/bus/pseudo/drivers/scsi_debug/add_host has the same effect as
rm_all_hosts so rm_all_hosts was not needed.

To inhibit a race between two invocations of writes to add_host, a mutex

still being added.

The logic to remove (all) hosts is rather crude: it works backwards down a
linked lists of hosts. Any pending requests are terminated with
DID_NO_CONNECT as are any new requests. In the case where not all hosts are
being removed, the ones that remain may have lost requests as just
outlined. The lowest numbered host (id) hosts will remain.

scsi: qla2xxx: Implement ref count for SRB

The timeout handler and the done function are racing. When
qla2x00_async_iocb_timeout() starts to run it can be preempted by the
normal response path (via the firmware?). qla24xx_async_gpsc_sp_done()
releases the SRB unconditionally. When scheduling back to
qla2x00_async_iocb_timeout() qla24xx_async_abort_cmd() will access an freed
sp->qpair pointer:

  qla2xxx [0000:83:00.0]-2871:0: Async-gpsc timeout - hdl=63d portid=234500 50:06:0e:80:08:77:b6:21.

  IP: qla24xx_async_abort_cmd+0x1b/0x1c0 [qla2xxx]

Obvious solution to this is to introduce a reference counter. One reference
is taken for the normal code path (the 'good' case) and one for the timeout
path. As we always race between the normal good case and the timeout/abort
handler we need to serialize it. Also we cannot assume any order between
the handlers. Since this is slow path we can use proper synchronization via
locks.

When we are able to cancel a timer (del_timer returns 1) we know there
can't be any error handling in progress because the timeout handler hasn't
expired yet, thus we can safely decrement the refcounter by one.

If we are not able to cancel the timer, we know an abort handler is
running. We have to make sure we call sp->done() in the abort handlers
before calling kref_put().

scsi: zfcp: Fix failed recovery on gone remote port with non-NPIV FCP devices

Suppose we have an environment with a number of non-NPIV FCP devices
(virtual HBAs / FCP devices / zfcp "adapter"s) sharing the same physical
FCP channel (HBA port) and its I_T nexus. Plus a number of storage target
ports zoned to such shared channel. Now one target port logs out of the
fabric causing an RSCN. Zfcp reacts with an ADISC ELS and subsequent port
recovery depending on the ADISC result. This happens on all such FCP
devices (in different Linux images) concurrently as they all receive a copy
of this RSCN. In the following we look at one of those FCP devices.

Requests other than FSF_QTCB_FCP_CMND can be slow until they get a
response.

Depending on which requests are affected by slow responses, there are
different recovery outcomes. Here we want to fix failed recoveries on port
or adapter level by avoiding recovery requests that can be slow.

We need the cached N_Port_ID for the remote port "link" test with ADISC.
Just before sending the ADISC, we now intentionally forget the old cached
N_Port_ID. The idea is that on receiving an RSCN for a port, we have to
assume that any cached information about this port is stale.  This forces a
fresh new GID_PN [FC-GS] nameserver lookup on any subsequent recovery for
the same port. Since we typically can still communicate with the nameserver
efficiently, we now reach steady state quicker: Either the nameserver still
does not know about the port so we stop recovery, or the nameserver already
knows the port potentially with a new N_Port_ID and we can successfully and
quickly perform open port recovery.  For the one case, where ADISC returns
successfully, we re-initialize port->d_id because that case does not
involve any port recovery.

This also solves a problem if the storage WWPN quickly logs into the fabric
again but with a different N_Port_ID. Such as on virtual WWPN takeover
during target NPIV failover.
[https://www.redbooks.ibm.com/abstracts/redp5477.html] In that case the
RSCN from the storage FDISC was ignored by zfcp and we could not
successfully recover the failover. On some later failback on the storage,
we could have been lucky if the virtual WWPN got the same old N_Port_ID
from the SAN switch as we still had cached.  Then the related RSCN
triggered a successful port reopen recovery.  However, there is no
guarantee to get the same N_Port_ID on NPIV FDISC.

Even though NPIV-enabled FCP devices are not affected by this problem, this
code change optimizes recovery time for gone remote ports as a side effect.
The timely drop of cached N_Port_IDs prevents unnecessary slow open port
attempts.

While the problem might have been in code before v2.6.32 commit
799b76d09aee ("[SCSI] zfcp: Decouple gid_pn requests from erp") this fix
depends on the gid_pn_work introduced with that commit, so we mark it as
culprit to satisfy fix dependencies.

Note: Point-to-point remote port is already handled separately and gets its
N_Port_ID from the cached peer_d_id. So resetting port->d_id in general
does not affect PtP.

scsi: pm8001: Fix bogus FW crash for maxcpus=1

According to the comment in check_fw_ready() we should not check the
IOP1_READY field in register SCRATCH_PAD_1 for 8008 or 8009 controllers.

However we check this very field in process_oq() for processing the highest
index interrupt vector. The highest interrupt vector is checked as the FW
is programmed to signal fatal errors through this irq.

Change that function to not check IOP1_READY for those mentioned
controllers, but do check ILA_READY in both cases.

The reason I assume that this was not hit earlier was because we always
allocated 64 MSI(X), and just did not pass the vector index check in
process_oq(), i.e.  the handler never ran for vector index 63.

Pull ftrace fix from Steven Rostedt:
 "Fix s390 breakage from sorting mcount tables.

  The latest merge of the tracing tree sorts the mcount table at build
  time. But s390 appears to do things differently (like always) and
  replaces the sorted table back to the original unsorted one. As the
  ftrace algorithm depends on it being sorted, bad things happen when it
  is not, and s390 experienced those bad things.

  Add a new config to tell the boot if the mcount table is sorted or
  not, and allow s390 to opt out of it"

* tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
  ftrace: Fix assuming build time sort works for s390

ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.

Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

  perf record -c 10000 -e arm_spe_0// -- sleep 1

Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.

This patch restores the previous behaviour for non-libpfm4 events.

Fixes: ae5dcc8abe31 (“perf record: Prevent override of attr->sample_period for libpfm4 events”)

perf script: Fix printing 'phys_addr' failure issue

Perf script was failed to print the phys_addr for SPE profiling.
One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR
attribute set, perf script then exits with error.

Now referring to 'addr', use evsel__do_check_stype() to check the type.

Before:

  # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
  # perf script -F pid,tid,addr,phys_addr
  Samples for 'dummy:u' event do not have PHYS_ADDR attribute set. Cannot print 'phys_addr' field.

After:

  # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
  # perf script -F pid,tid,addr,phys_addr
