commit a66307d473 upstream.
The ASMedia 1092 has a configuration mode which will present a
dummy device; sadly the implementation falsely claims to provide
a device with 100M which doesn't actually exist.
So disable this device to avoid errors during boot.

commit f971a85439 upstream.
Checking if DMA is enabled should be done via the
ata_dma_enabled helper function, since the init state
0xff indicates disabled.
This meant that ATA_CMD_READ_LOG_DMA_EXT was used and probed
for before DMA was enabled, which caused hangs for some combinations
of controllers and devices.
It might also have caused it to be incorrectly disabled as broken,
but there have been no reports of that.

commit 7a8526a5cd upstream.
Many users are reporting that the Samsung 860 and 870 SSD are having
various issues when combined with AMD/ATI (vendor ID 0x1002) SATA
controllers and only completely disabling NCQ helps to avoid these
issues.
Always disabling NCQ for Samsung 860/870 SSDs regardless of the host
SATA adapter vendor will cause I/O performance degradation with well
behaved adapters. To limit the performance impact to ATI adapters,
introduce the ATA_HORKAGE_NO_NCQ_ON_ATI flag to force disable NCQ
only for these adapters.
Also, two libata.force parameters (noncqati and ncqati) are introduced
to disable and enable the NCQ for the system which equipped with ATI
SATA adapter and Samsung 860 and 870 SSDs. The user can determine NCQ
function to be enabled or disabled according to the demand.
After verifying the chipset from the user reports, the issue appears
on AMD/ATI SB7x0/SB8x0/SB9x0 SATA Controllers and does not appear on
recent AMD SATA adapters. The vendor ID of ATI should be 0x1002.
Therefore, ATA_HORKAGE_NO_NCQ_ON_AMD was modified to
ATA_HORKAGE_NO_NCQ_ON_ATI.

commit 8a6430ab9c upstream.
Commit ca6bfcb2f6 ("libata: Enable queued TRIM for Samsung SSD 860")
limited the existing ATA_HORKAGE_NO_NCQ_TRIM quirk from "Samsung SSD 8*",
covering all Samsung 800 series SSDs, to only apply to "Samsung SSD 840*"
and "Samsung SSD 850*" series based on information from Samsung.
But there is a large number of users which is still reporting issues
with the Samsung 860 and 870 SSDs combined with Intel, ASmedia or
Marvell SATA controllers and all reporters also report these problems
going away when disabling queued trims.
Note that with AMD SATA controllers users are reporting even worse
issues and only completely disabling NCQ helps there, this will be
addressed in a separate patch.

commit 3b5455636f upstream.
All three generations of Sandisk SSDs lock up hard intermittently.
Experiments showed that disabling NCQ lowered the failure rate significantly
and the kernel has been disabling NCQ for some models of SD7's and 8's,
which is obviously undesirable.
Karthik worked with Sandisk to root cause the hard lockups to trim commands
larger than 128M. This patch implements ATA_HORKAGE_MAX_TRIM_128M which
limits max trim size to 128M and applies it to all three generations of
Sandisk SSDs.

With KASAN also enabled, we may also get many use-after-free reports.
The issue is that when CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, we may
attempt to detach the ata_port before it has been probed.
This is because the ata_ports are async probed, meaning that there is no
guarantee that the ata_port has probed prior to detach. When the ata_port
does probe in this scenario, we get all sorts of issues as the detach may
have already happened.
Fix by ensuring synchronisation with async_synchronize_full(). We could
alternatively use the cookie returned from the ata_port probe
async_schedule() call, but that means managing the cookie, so more
complicated.

commit 240630e618 upstream.
There have been several reports of LPM related hard freezes about once
a day on multiple Lenovo 50 series models. Strange enough these reports
where not disk model specific as LPM issues usually are and some users
with the exact same disk + laptop where seeing them while other users
where not seeing these issues.
It turns out that enabling LPM triggers a firmware bug somewhere, which
has been fixed in later BIOS versions.
This commit adds a new ahci_broken_lpm() function and a new ATA_FLAG_NO_LPM
for dealing with this.
The ahci_broken_lpm() function contains DMI match info for the 4 models
which are known to be affected by this and the DMI BIOS date field for
known good BIOS versions. If the BIOS date is older then the one in the
table LPM will be disabled and a warning will be printed.
Note the BIOS dates are for known good versions, some older versions may
work too, but we don't know for sure, the table is using dates from BIOS
versions for which users have confirmed that upgrading to that version
makes the problem go away.
Unfortunately I've been unable to get hold of the reporter who reported
that BIOS version 2.35 fixed the problems on the W541 for him. I've been
able to verify the DMI_SYS_VENDOR and DMI_PRODUCT_VERSION from an older
dmidecode, but I don't know the exact BIOS date as reported in the DMI.
Lenovo keeps a changelog with dates in their release notes, but the
dates there are the release dates not the build dates which are in DMI.
So I've chosen to set the date to which we compare to one day past the
release date of the 2.34 BIOS. I plan to fix this with a follow up
commit once I've the necessary info.

Commit 184add2ca2 ("libata: Apply NOLPM quirk for SanDisk
SD7UB3Q*G1001 SSDs") disabled LPM for SanDisk SD7UB3Q*G1001 SSDs.
This has lead to several reports of users of that SSD where LPM
was working fine and who know have a significantly increased idle
power consumption on their laptops.
Likely there is another problem on the T450s from the original
reporter which gets exposed by the uncore reaching deeper sleep
states (higher PC-states) due to LPM being enabled. The problem as
reported, a hardfreeze about once a day, already did not sound like
it would be caused by LPM and the reports of the SSD working fine
confirm this. The original reporter is ok with dropping the quirk.
A X250 user has reported the same hard freeze problem and for him
the problem went away after unrelated updates, I suspect some GPU
driver stack changes fixed things.
TL;DR: The original reporters problem were triggered by LPM but not
an LPM issue, so drop the quirk for the SSD in question.

commit d418ff56b8 upstream.
When commit 9c7be59fc5 ("libata: Apply NOLPM quirk to Crucial MX100

from the existing "Crucial_CT*MX100*" entry, but that entry sets model_rev
to "MU01", where as the entry adding the NOLPM quirk sets it to NULL.
This means that after this commit we no apply the NO_NCQ_TRIM quirk to
all "Crucial_CT512MX100*" SSDs even if they have the fixed "MU02"
firmware. This commit splits the "Crucial_CT512MX100*" quirk into 2
quirks, one for the "MU01" firmware and one for all other firmware
versions, so that we once again only apply the NO_NCQ_TRIM quirk to the
"MU01" firmware version.

LPM fixes in its changelog, so the quirk matches all firmware versions.
In my experience the LPM problems with (older) Crucial SSDs seem to be
limited to higher capacity versions of the SSDs (different firmware?),
so this commit adds a NOLPM quirk for the 480 and 960GB versions of the
M500, to avoid LPM causing issues with these SSDs.

commit b17e5729a6 upstream.
After Laptop Mode Tools starts to use min_power for LPM, a user found
out Crucial BX100 SSD can't get mounted.
Crucial BX100 SSD 500GB drive don't work well with min_power. This also
happens to med_power_with_dipm.
So let's disable LPM for Crucial BX100 SSD 500GB drive.

commit 9c7be59fc5 upstream.
Various people have reported the Crucial MX100 512GB model not working
with LPM set to min_power. I've now received a report that it also does
not work with the new med_power_with_dipm level.
It does work with medium_power, but that has no measurable power-savings
and given the amount of people being bitten by the other levels not
working, this commit just disables LPM altogether.
Note all reporters of this have either the 512GB model (max capacity), or
are not specifying their SSD's size. So for now this quirk assumes this is
a problem with the 512GB model only.

commit 9173e5e807 upstream.
syzkaller hit a WARN() in ata_qc_issue() when writing to /dev/sg0. This
happened because it issued a READ_6 command with no data buffer.
Just remove the WARN(), as it doesn't appear indicate a kernel bug. The
expected behavior is to fail the command, which the code does.
Here's a reproducer that works in QEMU when /dev/sg0 refers to a disk of
the default type ("82371SB PIIX3 IDE"):
#include <fcntl.h>
#include <unistd.h>
int main()
{
char buf[42] = { [36] = 0x8 /* READ_6 */ };
write(open("/dev/sg0", O_RDWR), buf, sizeof(buf));
}

Signed-off-by: Tejun Heo <tj@kernel.org>
ATA-8 and later mirrors the TRUSTED COMPUTING SUPPORTED bit in word 48 of
the IDENTIFY DEVICE data. Check this before issuing a READ LOG PAGE
command to avoid issues with buggy devices. The only downside is that
we can't support Security Send / Receive for a device with an older
revision due to the conflicting use of this field in earlier
specifications.
tj: The reason we need this is because some devices which don't
support READ LOG PAGE lock up after getting issued that command.

The warning message "READ LOG DMA EXT failed, trying unqueued" in
ata_read_log_page() as well as the macro name ATA_HORKAGE_NO_NCQ_LOG
are confusing: the command READ LOG DMA EXT is not an queued NCQ command
unless it is encapsulated in a RECEIVE FPDMA QUEUED command.
From ACS-4 READ LOG DMA EXT description:
"The device processes the READ LOG DMA EXT command in the NCQ feature
set environment (see 4.13.6) if the READ LOG DMA EXT command is
encapsulated in a RECEIVE FPDMA QUEUED command (see 7.30) with the
inputs encapsulated as shown in 7.23.6."
To avoid confusion, fix the warning messsage to mention switching to PIO and
not "unqueued" and rename the macro ATA_HORKAGE_NO_NCQ_LOG to
ATA_HORKAGE_NO_DMA_LOG.

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.

NCQ prio support is enabled.
