Handling CD-ROM devices from libsas is decidedly odd, as libata relies
on SCSI EH to be started to figure out that no medium is present. So we
cannot do asynchronous aborts for SATA devices.

When an I/O is returned with an srb_status of SRB_STATUS_INVALID_LUN
which has zero good_bytes it must be assigned an error. Otherwise the
I/O will be continuously requeued and will cause a deadlock in the case
where disks are being hot added and removed. sd_probe_async will wait
forever for its I/O to complete while holding scsi_sd_probe_domain.
Also returning the default error of DID_TARGET_FAILURE causes multipath
to not retry the I/O resulting in applications receiving I/O errors
before a failover can occur.

As it turned out device_get() doesn't use kref_get_unless_zero(), so we
will be always getting a device pointer. Consequently, we need to check
for the device state in __scsi_remove_target() to avoid tripping over
deleted objects.

"FIB_CONTEXT_FLAG_TIMEDOUT" flag is set in aac_eh_abort to indicate
command timeout. Using the same flag in reset handler causes the command
to time out and the I/Os were dropped.
Define a new flag "FIB_CONTEXT_FLAG_EH_RESET" to make sure I/O is
properly handled in eh_reset handler.

Avoid that scsi_show_rq() triggers a NULL pointer dereference if called
after sd_uninit_command(). Swap the NULL pointer assignment and the
mempool_free() call in sd_uninit_command() to make it less likely that
scsi_show_rq() triggers a use-after-free. Note: even with these changes
scsi_show_rq() can trigger a use-after-free but that's a lesser evil
than e.g. suppressing debug information for T10 PI Type 2 commands
completely. This patch fixes the following oops:

The return value of smp_execute_task_sg() is the untransferred residual,
but bsg_job_done() requires the length of payload received. This makes
SMP passthrough commands from userland by sg ioctl to libsas get a wrong
response. The userland tools such as smp_utils failed because of these
wrong responses:
~#smp_discover /dev/bsg/expander-2\:13
response too short, len=0
~#smp_discover /dev/bsg/expander-2\:134
response too short, len=0
Fix this by passing the actual received length to bsg_job_done(). And if
smp_execute_task_sg() returns 0, this means received length is exactly
the buffer length.

This changes the code back to shost_priv() once more, but encapsulates
it in an inline function to document the rather unusual way of
using the private data only as a pointer to the previously allocated
structure.
I did not try to get rid of the extra indirection level entirely,

Before commit 0df21c86bdbf ("scsi: implement .get_budget and .put_budget
for blk-mq"), we run queue after 3ms if queue is idle and SCSI device
queue isn't ready, which is done in handling BLK_STS_RESOURCE. After
commit 0df21c86bdbf is introduced, queue won't be run any more under
this situation.
IO hang is observed when timeout happened, and this patch fixes the IO
hang issue by running queue after delay in scsi_dev_queue_ready, just
like non-mq. This issue can be triggered by the following script[1].
There is another issue which can be covered by running idle queue: when
.get_budget() is called on request coming from hctx->dispatch_list, if
one request just completes during .get_budget(), we can't depend on
SCSI's restart to make progress any more. This patch fixes the race too.
With this patch, we basically recover to previous behaviour (before
commit 0df21c86bdbf) of handling idle queue when running out of
resource.

As reported by Meelis Roos, my previous patch causes an incorrect
calculation of the timeout, through an undefined signed integer
overflow:
[ 12.228155] UBSAN: Undefined behaviour in drivers/scsi/aacraid/commsup.c:2514:49
[ 12.228229] signed integer overflow:
[ 12.228283] 964297611 * 250 cannot be represented in type 'long int'
The problem is that doing a multiplication with HZ first and then
dividing by USEC_PER_SEC worked correctly for 32-bit microseconds,
but not for 32-bit nanoseconds, which would require up to 41 bits.
This reworks the calculation to first convert the nanoseconds into
jiffies, which should give us the same result as before and not overflow.
Unfortunately I did not understand the exact intention of the algorithm,
in particular the part where we add half a second, so it's possible that
there is still a preexisting problem in this function. I added a comment
that this would be handled more nicely using usleep_range(), which
generally works better for waking up at a particular time than the
current schedule_timeout() based implementation. I did not feel
comfortable trying to implement that without being sure what the
intent is here though.

maintain I/O coherency, so scsi's block queue should be aligned to the
value returned by dma_get_cache_alignment(). Otherwise, If a DMA buffer

structure has dirty data, cache_invalidate (no writeback) will cause

As part of the scsi EH path, aacraid performs a reinitialization of the
adapter, which encompass freeing resources and IRQs, NULLifying lots of
pointers, and then initialize it all over again. We've identified a
problem during the free IRQ portion of this path if CONFIG_DEBUG_SHIRQ
is enabled on kernel config file.
Happens that, in case this flag was set, right after free_irq()
effectively clears the interrupt, it checks if it was requested as
IRQF_SHARED. In positive case, it performs another call to the IRQ
handler on driver. Problem is: since aacraid currently free some
resources *before* freeing the IRQ, once free_irq() path calls the
handler again (due to CONFIG_DEBUG_SHIRQ), aacraid crashes due to NULL
pointer dereference with the following trace:
aac_src_intr_message+0xf8/0x740 [aacraid]
__free_irq+0x33c/0x4a0
free_irq+0x78/0xb0
aac_free_irq+0x13c/0x150 [aacraid]

scsi_eh_ready_devs+0xc70/0x1510
scsi_error_handler+0x624/0xa20
This patch prevents the crash by changing the order of the
deinitialization in this path of aacraid: first we clear the IRQ, then
we free other resources. No functional change intended.

Currently the driver accepts two ways of requesting an initialization
reset on the adapter: by passing aac_reset_devices module parameter,
or the generic kernel parameter reset_devices.
It's working as intended...but if we end up reaching a scsi hang and
the scsi EH mechanism takes place, aacraid performs resets as part of
the scsi error recovery procedure. These EH routines might reinitialize
the device, and if we have provided some of the reset parameters in the
kernel command-line, we again perform an "initialization" reset.
So, to avoid this duplication of resets in case of scsi EH path, this
patch adds a field to aac_dev struct to keep per-adapter track of the
init reset request - once it's done, we set it to false and don't
proactively reset anymore in case of reinitializations.

Commit 16ae9dd35d37 ("scsi: aacraid: Fix for excessive prints on EEH")
introduced checks about the state of device before any PCI operations in
the driver. Basically, this prevents it to perform PCI accesses when
device is in the process of recover from a PCI error. In PowerPC, such
mechanism is called EEH, and the aforementioned commit introduced checks
that are based on EEH-specific primitives for that.
The potential problems with this approach are three: first, these checks
are "locked" to powerpc only - another archs could have error recovery
methods too, like AER in Intel. Also, the powerpc primitives perform
expensive FW accesses to validate the precise PCI state of a device.
Finally, code becomes more complicated and needs ifdef validation based
on arch config being set.
So, this patch makes use of generic PCI state checks, which are
lightweight and non-dependent of arch configs - also, it makes the code
cleaner.

Pull IPMI updates from Corey Minyard:
"This is a fairly large rework of the IPMI code, along with a bunch of
smaller fixes. The major changes have been in the next tree for a
couple of months, so they should be good to do in.
- Some users had IPMI systems where the GUID of the IPMI controller
could change. So rescanning of the GUID was added. The naming of
some sysfs things was dependent on the GUID, however, so this
resulted in the sysfs interface code in IPMI changing to remove
that dependency and name the IPMI BMCs like other sysfs devices.

Pull rdma updates from Doug Ledford:
"This is a fairly plain pull request. Lots of driver updates across the
stack, a huge number of static analysis cleanups including a close to
50 patch series from Bart Van Assche, and a number of new features
inside the stack such as general CQ moderation support.
Nothing really stands out, but there might be a few conflicts as you
take things in. In particular, the cleanups touched some of the same
lines as the new timer_setup changes.
Everything in this pull request has been through 0day and at least two
days of linux-next (since Stephen doesn't necessarily flag new
errors/warnings until day2). A few more items (about 30 patches) from
Intel and Mellanox showed up on the list on Tuesday. I've excluded
those from this pull request, and I'm sure some of them qualify as
fixes suitable to send any time, but I still have to review them
fully. If they contain mostly fixes and little or no new development,
then I will probably send them through by the end of the week just to
get them out of the way.
There was a break in my acceptance of patches which coincides with the
computer problems I had, and then when I got things mostly back under
control I had a backlog of patches to process, which I did mostly last
Friday and Monday. So there is a larger number of patches processed in
that timeframe than I was striving for.
Summary:
- Add iWARP support to qedr driver
- Lots of misc fixes across subsystem
- Multiple update series to hns roce driver
- Multiple update series to hfi1 driver
- Updates to vnic driver
- Add kref to wait struct in cxgb4 driver
- Updates to i40iw driver

Pull arm64 updates from Will Deacon:
"The big highlight is support for the Scalable Vector Extension (SVE)
which required extensive ABI work to ensure we don't break existing
applications by blowing away their signal stack with the rather large
new vector context (<= 2 kbit per vector register). There's further
work to be done optimising things like exception return, but the ABI
is solid now.
Much of the line count comes from some new PMU drivers we have, but
they're pretty self-contained and I suspect we'll have more of them in
future.
Plenty of acronym soup here:
- initial support for the Scalable Vector Extension (SVE)
- improved handling for SError interrupts (required to handle RAS
events)
- enable GCC support for 128-bit integer types
- remove kernel text addresses from backtraces and register dumps
- use of WFE to implement long delay()s
- ACPI IORT updates from Lorenzo Pieralisi
- perf PMU driver for the Statistical Profiling Extension (SPE)

geneve->sock4/6 were added with geneve_open and released with geneve_stop.
So when geneve link down, we will not able to show remote address and
checksum info after commit 11387fe4a98 ("geneve: fix fill_info when using
collect_metadata").
Fix this by avoid passing *_REMOTE{,6} for COLLECT_METADATA since they are
mutually exclusive, and always show UDP_ZERO_CSUM6_RX info.

The GetNtbFormat and SetNtbFormat requests operate on 16 bit little
endian values. We get away with ignoring this most of the time, because
we only care about USB_CDC_NCM_NTB16_FORMAT which is 0x0000. This
fails for USB_CDC_NCM_NTB32_FORMAT.
Fix comparison between LE value from device and constant by converting
the constant to LE.

and HP Elite book x360) support from Masaki Ota

iOS devices require the host to be "trusted" before servicing network
packets. Establishing trust requires the user to confirm a dialog on the
iOS device.Until trust is established, the iOS device will silently discard
network packets from the host. Currently, the ipheth driver does not detect
whether an iOS device has established trust with the host, and immediately
sets up the transmit queues.
This causes the following problems:
- Kernel taint due to WARN() in netdev watchdog.
- Dmesg spam ("TX timeout").
- Disruption of user space networking activity (dhcpd, etc...) when new
interface comes up but cannot be used.
- Unnecessary host and device wakeups and USB traffic
Example dmesg output:

[ 1101.320110] ipheth 1-5:4.2: ipheth_tx_timeout: TX timeout
The last message "TX timeout" is repeated every 5 seconds until trust is
established or the device is disconnected, filling up dmesg.
The proposed patch eliminates the problem by, upon connection, keeping the
TX queue and carrier disabled until a packet is first received from the iOS
device. This is reflected by the confirmed_pairing variable in the device
structure. Only after at least one packet has been received from the iOS
device, the transmit queue and carrier are brought up during the periodic
device poll in ipheth_carrier_set. Because the iOS device will always send
a packet immediately upon trust being established, this should not delay
the interface becoming useable. To prevent failed UBRs in
ipheth_rcvbulk_callback from perpetually re-enabling the queue if it was
disabled, a new check is added so only successful transfers re-enable the
queue, whereas failed transfers only trigger an immediate poll.
This has the added benefit of removing the periodic control requests to the
iOS device until trust has been established and thus should reduce wakeup
events on both the host and the iOS device.

We always poll tx for socket, this is sub optimal since this will
slightly increase the waitqueue traversing time and more important,
vhost could not benefit from commit 9e641bdcfa4e ("net-tun:
restructure tun_do_read for better sleep/wakeup efficiency") even if
we've stopped rx polling during handle_rx(), tx poll were still left
in the waitqueue.
Pktgen from a remote host to VM over mlx4 on two 2.00GHz Xeon E5-2650
shows 11.7% improvements on rx PPS. (from 1.28Mpps to 1.44Mpps)

Pull DeviceTree updates from Rob Herring:
"A bigger diffstat than usual with the kbuild changes and a tree wide
fix in the binding documentation.
Summary:
- kbuild cleanups and improvements for dtbs
- Code clean-up of overlay code and fixing for some long standing
memory leak and race condition in applying overlays
- Improvements to DT memory usage making sysfs/kobjects optional and
skipping unflattening of disabled nodes. This is part of kernel
tinification efforts.
- Final piece of removing storing the full path for every DT node.
The prerequisite conversion of printk's to use device_node format
specifier happened in 4.14.
- Sync with current upstream dtc. This brings additional checks to
dtb compiling.
- Binding doc tree wide removal of leading 0s from examples
- RTC binding documentation adding missing devices and some
consolidation of duplicated bindings
- Vendor prefix documentation for nutsboard, Silicon Storage
Technology, shimafuji, Tecon Microprocessor Technologies, DH
electronics GmbH, Opal Kelly, and Next Thing"
