[ Upstream commit 59a5e266c3f5c1567508888dd61a45b86daed0fa ]
My static checker complains that "devno" can be negative, meaning that
we read before the start of the loop. I've looked at the code, and I
think the warning is right. This come from /proc so it's root only or
it would be quite a quite a serious bug. The call tree looks like this:
proc_scsi_write() <- gets id and channel from simple_strtoul()
-> scsi_add_single_device() <- calls shost->transportt->user_scan()
-> ata_scsi_user_scan()
-> ata_find_dev()

[ Upstream commit 2dae99558e86894e9e5dbf097477baaa5eb70134 ]
For an ATA device supporting the sense data reporting feature set, a
failed command will trigger the execution of ata_eh_request_sense if
the result task file of the failed command has the ATA_SENSE bit set
(sense data available bit). ata_eh_request_sense executes the REQUEST
SENSE DATA EXT command to retrieve the sense data of the failed
command. On success of REQUEST SENSE DATA EXT, the ATA_SENSE bit will
NOT be set (the command succeeded) but ata_eh_request_sense
nevertheless tests the availability of sense data by testing that bit
presence in the result tf of the REQUEST SENSE DATA EXT command. This
leads us to falsely assume that request sense data failed and to the
warning message:
atax.xx: request sense failed stat 50 emask 0
Upon success of REQUEST SENSE DATA EXT, set the ATA_SENSE bit in the
result task file command so that sense data can be returned by
ata_eh_request_sense.

[ Upstream commit 72d8c36ec364c82bf1bf0c64dfa1041cfaf139f7 ]
sas_ata_strategy_handler() adds the works of the ata error handler to
system_unbound_wq. This workqueue asynchronously runs work items, so the
ata error handler will be performed concurrently on different CPUs. In
this case, ->host_failed will be decreased simultaneously in
scsi_eh_finish_cmd() on different CPUs, and become abnormal.
It will lead to permanently inequality between ->host_failed and
->host_busy, and scsi error handler thread won't start running. IO
errors after that won't be handled.
Since all scmds must have been handled in the strategy handler, just
remove the decrement in scsi_eh_finish_cmd() and zero ->host_busy after
the strategy handler to fix this race.

[ Upstream commit 17dcc37e3e847bc0e67a5b1ec52471fcc6c18682 ]
On some SOCs PORTS_IMPL register value is never programmed by the
firmware and left at zero value. Which means that no sata ports are
available for software. AHCI driver used to cope up with this by
fabricating the port_map if the PORTS_IMPL register is read zero,
but recent patch broke this workaround as zero value was valid for
NVMe disks.
This patch adds ports-implemented DT bindings as workaround for this issue
in a way that DT can can override the PORTS_IMPL register in cases where
the firmware did not program it already.

[ Upstream commit 287e6611ab1eac76c2c5ebf6e345e04c80ca9c61 ]
As reported by Soohoon Lee, the HDIO_GET_32BIT ioctl does not
work correctly in compat mode with libata.
I have investigated the issue further and found multiple problems
that all appeared with the same commit that originally introduced
HDIO_GET_32BIT handling in libata back in linux-2.6.8 and presumably
also linux-2.4, as the code uses "copy_to_user(arg, &val, 1)" to copy
a 'long' variable containing either 0 or 1 to user space.
The problems with this are:
* On big-endian machines, this will always write a zero because it
stores the wrong byte into user space.
* In compat mode, the upper three bytes of the variable are updated
by the compat_hdio_ioctl() function, but they now contain
uninitialized stack data.
* The hdparm tool calling this ioctl uses a 'static long' variable
to store the result. This means at least the upper bytes are
initialized to zero, but calling another ioctl like HDIO_GET_MULTCOUNT
would fill them with data that remains stale when the low byte
is overwritten. Fortunately libata doesn't implement any of the
affected ioctl commands, so this would only happen when we query
both an IDE and an ATA device in the same command such as
"hdparm -N -c /dev/hda /dev/sda"
* The libata code for unknown reasons started using ATA_IOC_GET_IO32
and ATA_IOC_SET_IO32 as aliases for HDIO_GET_32BIT and HDIO_SET_32BIT,
while the ioctl commands that were added later use the normal
HDIO_* names. This is harmless but rather confusing.
This addresses all four issues by changing the code to use put_user()
on an 'unsigned long' variable in HDIO_GET_32BIT, like the IDE subsystem
does, and by clarifying the names of the ioctl commands.

[ Upstream commit 8eee1d3ed5b6fc8e14389567c9a6f53f82bb7224 ]
The bulk of ATA host state machine is implemented by
ata_sff_hsm_move(). The function is called from either the interrupt
handler or, if polling, a work item. Unlike from the interrupt path,
the polling path calls the function without holding the host lock and
ata_sff_hsm_move() selectively grabs the lock.
This is completely broken. If an IRQ triggers while polling is in
progress, the two can easily race and end up accessing the hardware
and updating state machine state at the same time. This can put the
state machine in an illegal state and lead to a crash like the
following.

[ Upstream commit 566d1827df2ef0cbe921d3d6946ac3007b1a6938 ]
Some early controllers incorrectly reported zero ports in PORTS_IMPL
register and the ahci driver fabricates PORTS_IMPL from the number of

be honored.

When a read command returns less data than specified in the PRDs (for
example, there are two PRDs for this command, but the device returns a
number of bytes which is less than in the first PRD), the second PRD of
this command is not read out of the PRD FIFO, causing the next command
to use this PRD erroneously.

commit 91f15fb30c77d4a0d0d9b97e5cec647650853145 upstream.
On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at
function 1 doesn't work if it is powered on before the SATA controller at
function 0. The result is that PATA doesn't work after resume, and we
print messages like this:
pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3
irq 17: nobody cared (try booting with the "irqpoll" option)
Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep:
Asynchronous threads for resume_noirq"). Prior to that, we powered on
the functions in order, so this problem shouldn't happen.
e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361")
solved the problem for JMicron 361 and 363 devices. With async suspend
disabled, we always power on function 0 before function 1.
Barto then reported the same problem with a JMicron 368 (see comment #57 in
the bugzilla).
Rather than extending the blacklist piecemeal, disable async suspend for
all JMicron multi-function SATA/PATA/AHCI devices.
This quirk could stay in the ahci and pata_jmicron drivers, but it's likely
the problem will occur even if pata_jmicron isn't loaded until after the
suspend/resume. Making it a PCI quirk ensures that we'll preserve the
power-on order even if the drivers aren't loaded.

commit 945b47441d83d2392ac9f984e0267ad521f24268 upstream.
This commit adds the necessary quirk to make the Marvell 4140 SATA PMP
work properly. This PMP doesn't like SRST on port number 4 (the host
port) so this commit marks this port as not supporting SRST.

commit eab6ee1ce3c4678224d70338134f7a02005768cb upstream.
Commit 5d3abf8ff67f ("libata: Fall back to unqueued READ LOG EXT if
the DMA variant fails") allowed us to fall back to the unqueued READ
LOG variant if the queued version failed. However, if the device did
not support the page at all we would end up looping due to a merge
snafu.
Ensure we only take the fallback path once.

limit
commit af34d637637eabaf49406eb35c948cd51ba262a6 upstream.
Since no longer limiting max_sectors to BLK_DEF_MAX_SECTORS (commit 34b48db66e08),
data corruption may occur on ST380013AS drive configured on 82801JI (ICH10 Family)
SATA controller. This patch will allow the driver to limit max_sectors as before
# cat /sys/block/sdb/queue/max_sectors_kb
512
I was able to double the max_sectors_kb value up to 16384 on linux-4.2.0-rc2
before seeing corruption, but seems safer to use previous limit. Without this
patch max_sectors_kb will be 32767.

Some devices advertise support for the READ/WRITE LOG DMA EXT commands

commit d531be2ca2f27cca5f041b6a140504999144a617 upstream.
I have a ST4000DM000 disk. If Linux is booted while the disk is spun down,
the command that sets transfer mode causes the disk to spin up. The
spin-up takes longer than the default 5s timeout, so the command fails and
timeout is reported.
Fix this by increasing the timeout to 15s, which is enough for the disk to
spin up.

According to the Armada 38x datasheet, the window base address
registers value is set in bits [31:4] of the register and corresponds
to the transaction address bits [47:20].
Therefore, the 32bit base address value should be shifted right by
20bits and left by 4bits, resulting in 16 bit shift right.
The bug as not been noticed yet because if the memory available on
the platform is less than 2GB, then the base address is zero.

"Rather big for fixes pull.
- SCC controllers never lived to see the light of the day. Both

- In some configurations, link power management policy changes
sometimes cause delayed spurious PHY events which can develop into

years. Gabriele's patches suppress PHY events for a while after
LPM policy changes which should help most of these failures without
causing too much problem for hotplug use cases.
- A few controller specific fixes"

When the LPM policy is set to ATA_LPM_MAX_POWER, the device might
generate a spurious PHY event that cuases errors on the link.
Ignore this event if it occured within 10s after the policy change.
The timeout was chosen observing that on a Dell XPS13 9333 these
spurious events can occur up to roughly 6s after the policy change.

Brian noticed while working on another SATA driver that uses libahci_platform,
an error in this driver; it tries to the the driver data for its
device, while libata also thinks it can set the driver data. See:
ahci_platform_init_host()
-> ata_host_alloc_pinfo()
-> ata_host_alloc()
-> dev_set_drvdata()
So instead of sticking the IP-specific platform data into drvdata, let's
use the plat_data variable that is reserved for this use.
Addtionally plat_data isn't set until ahci_platform_init_host() has been
called further down in probe(). So re-work the st_ahci_probe_resets and
st_ahci_deassert_resets functions to take ahci_host_priv *hpriv as a
parameter.
