[ Upstream commit 4414b3ed74be0e205e04e12cd83542a727d88255 ]
Some ethernet drivers (like TI CPSW) may connect and manage >1 Net PHYs per
one netdevice, as result such drivers will produce warning during system
boot and fail to connect second phy to netdevice when PHYLIB framework
will try to create sysfs link netdev->phydev for second PHY
in phy_attach_direct(), because sysfs link with the same name has been
created already for the first PHY. As result, second CPSW external
port will became unusable.
Fix it by relaxing error checking when PHYLIB framework is creating sysfs
link netdev->phydev in phy_attach_direct(), suppressing warning by using
sysfs_create_link_nowarn() and adding error message instead.
After this change links (phy->netdev and netdev->phy) creation failure is not
fatal any more and system can continue working, which fixes TI CPSW issue.

commit cd3f1790b006d91786728c20a01da21ee277aff1 upstream.
xhci_disable_slot() allows the invoker to pass a command pointer
as paramenter. Otherwise, it will allocate one. This will cause
memory leak when a command structure was allocated inside of this
function while queuing command trb fails. Another problem comes up
when the invoker passed a command pointer, but xhci_disable_slot()
frees it when it detects a dead host.
This patch fixes these two problems by removing the command parameter
from xhci_disable_slot().

commit b64149ca016c25f30b39ac5a8f37cfb9017e19bb upstream.
xhci_disable_slot() is a helper for disabling a slot when a device
goes away or recovers from error situations. Currently, it checks
the corespoding virt-dev pointer and returns directly (w/o issuing
disable slot command) if it's null.
This is unnecessary and will cause problems in case where virt-dev
allocation fails and xhci_disable_slot() is called to roll back the
hardware state. Refer to the implementation of xhci_alloc_dev().
This patch removes lines to check virt-dev in xhci_disable_slot().

Dave pointed out that clearing the syncobj->file from

opens a can of worm since we assumed that the syncobj->file was never
unset. Stop trying to reuse the same struct file for every fd pointing
to the drm_syncobj, and allocate one file for each fd instead.

commit 746201235b3f876792099079f4c6fea941d76183 upstream.
While waiting for the TX object to send an RTR, an external message with a
matching id can overwrite the TX data. In this case we must call the rx
routine and then try transmitting the message that was overwritten again.
The queue was being stalled because the RX event did not generate an
interrupt to wake up the queue again and the TX event did not happen
because the TXRQST flag is reset by the chip when new data is received.
According to the CC770 datasheet the id of a message object should not be
changed while the MSGVAL bit is set. This has been fixed by resetting the
MSGVAL bit before modifying the object in the transmit function and setting
it after. It is not enough to set & reset CPUUPD.
It is important to keep the MSGVAL bit reset while the message object is
being modified. Otherwise, during RTR transmission, a frame with matching
id could trigger an rx-interrupt, which would cause a race condition
between the interrupt routine and the transmit function.

commit 880dd464b4304583c557c4e5f5ecebfd55d232b1 upstream.
The new version of the IFI CANFD core has significantly less complex
error state indication logic. In particular, the warning/error state
bits are no longer all over the place, but are all present in the
STATUS register. Moreover, there is a new IRQ register bit indicating
transition between error states (active/warning/passive/busoff).
This patch makes use of this bit to weed out the obscure selective
INTERRUPT register clearing, which was used to carry over the error
state indication into the poll function. While at it, this patch
fixes the handling of the ACTIVE state, since the hardware provides
indication of the core being in ACTIVE state and that in turn fixes
the state transition indication toward userspace. Finally, register
reads in the poll function are moved to the matching subfunctions
since those are also no longer needed in the poll function.

commit 455f3e76cfc0d893585a5f358b9ddbe9c1e1e53b upstream.
The firmware has a requirement that the P2P_DEVICE address should
be different from the address of the primary interface. When not
specified by user-space, the driver generates the MAC address for
the P2P_DEVICE interface using the MAC address of the primary
interface and setting the locally administered bit. However, the MAC
address of the primary interface may already have that bit set causing
the creation of the P2P_DEVICE interface to fail with -EBUSY. Fix this
by using a random address instead to determine the P2P_DEVICE address.

Prior to 25520d55cdb6 ("block: Inline blk_integrity in struct gendisk")
we needed to temporarily add a zero-capacity disk before registering for
blk-integrity. But adding a zero-capacity disk caused the partition
table scanning to bail early, and this resulted in partitions not coming
up after a probe of the BTT or blk namespaces.
We can now register for integrity before the disk has been added, and
this fixes the rescan problems.

commit 73a88250b70954a8f27c2444e1c2411bba3c29d9 upstream.
When validating legacy surfaces, the backup bo might be destroyed at
surface validate time. However, the kms resource validation code may have
the bo reserved, so we will destroy a locked mutex. While there shouldn't
be any other users of that mutex when it is destroyed, it causes a lock
leak and thus throws a lockdep error.
Fix this by having the kms resource validation code hold a reference to
the bo while we have it reserved. We do this by introducing a validation
context which might come in handy when the kms code is extended to validate
multiple resources or buffers.

When we are running without fbdev, transitioning from the login screen to
X or gnome-shell/wayland will cause a vt switch and the driver will disable

will cause device errors when we try to bind an fb to the crtc, and the

commit d418ff56b8f2d2b296daafa8da151fe27689b757 upstream.
When commit 9c7be59fc519af ("libata: Apply NOLPM quirk to Crucial MX100
512GB SSDs") was added it inherited the ATA_HORKAGE_NO_NCQ_TRIM quirk
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.

commit 3bf7b5d6d017c27e0d3b160aafb35a8e7cfeda1f upstream.
Commit b17e5729a630 ("libata: disable LPM for Crucial BX100 SSD 500GB
drive"), introduced a ATA_HORKAGE_NOLPM quirk for Crucial BX100 500GB SSDs
but limited this to the MU02 firmware version, according to:
http://www.crucial.com/usa/en/support-ssd-firmware
MU02 is the last version, so there are no newer possibly fixed versions
and if the MU02 version has broken LPM then the MU01 almost certainly
also has broken LPM, so this commit changes the quirk to apply to all
firmware versions.

commit 62ac3f7305470e3f52f159de448bc1a771717e88 upstream.
There have been reports of the Crucial M500 480GB model not working
with LPM set to min_power / med_power_with_dipm level.
It has not been tested with medium_power, but that typically has no
measurable power-savings.
Note the reporters Crucial_CT480M500SSD3 has a firmware version of MU03
and there is a MU05 update available, but that update does not mention any
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 b17e5729a630d8326a48ec34ef02e6b4464a6aef 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 9c7be59fc519af9081c46c48f06f2b8fadf55ad8 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 2c1ec6fda2d07044cda922ee25337cf5d4b429b3 upstream.
syzkaller hit a WARN() in ata_bmdma_qc_issue() when writing to /dev/sg0.
This happened because it issued an ATA pass-through command (ATA_16)
where the protocol field indicated that NCQ should be used -- but the
device did not support NCQ.
We could just remove the WARN() from libata-sff.c, but the real problem
seems to be that the SCSI -> ATA translation code passes through NCQ
commands without verifying that the device actually supports NCQ.
Fix this by adding the appropriate check to ata_scsi_pass_thru().
Here's 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[53] = { 0 };
buf[36] = 0x85; /* ATA_16 */
buf[37] = (12 << 1); /* FPDMA */
buf[38] = 0x1; /* Has data */
buf[51] = 0xC8; /* ATA_CMD_READ */
write(open("/dev/sg0", O_RDWR), buf, sizeof(buf));
}

commit 9173e5e80729c8434b8d27531527c5245f4a5594 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

commit 058f58e235cbe03e923b30ea7c49995a46a8725f upstream.
syzkaller reported a crash in ata_bmdma_fill_sg() when writing to
/dev/sg1. The immediate cause was that the ATA command's scatterlist
was not DMA-mapped, which causes 'pi - 1' to underflow, resulting in a
write to 'qc->ap->bmdma_prd[0xffffffff]'.
Strangely though, the flag ATA_QCFLAG_DMAMAP was set in qc->flags. The
root cause is that when __ata_scsi_queuecmd() is preparing to relay a
SCSI command to an ATAPI device, it doesn't correctly validate the CDB
length before copying it into the 16-byte buffer 'cdb' in 'struct
ata_queued_cmd'. Namely, it validates the fixed CDB length expected
based on the SCSI opcode but not the actual CDB length, which can be
larger due to the use of the SG_NEXT_CMD_LEN ioctl. Since 'flags' is
the next member in ata_queued_cmd, a buffer overflow corrupts it.
Fix it by requiring that the actual CDB length be <= 16 (ATAPI_CDB_LEN).
[Really it seems the length should be required to be <= dev->cdb_len,
but the current behavior seems to have been intentionally introduced by
commit 607126c2a21c ("libata-scsi: be tolerant of 12-byte ATAPI commands
in 16-byte CDBs") to work around a userspace bug in mplayer. Probably
the workaround is no longer needed (mplayer was fixed in 2007), but
continuing to allow lengths to up 16 appears harmless for now.]
Here's a reproducer that works in QEMU when /dev/sg1 refers to the
CD-ROM drive that qemu-system-x86_64 creates by default:
#include <fcntl.h>
#include <sys/ioctl.h>
#include <unistd.h>
#define SG_NEXT_CMD_LEN 0x2283
int main()
{
char buf[53] = { [36] = 0x7e, [52] = 0x02 };
int fd = open("/dev/sg1", O_RDWR);
ioctl(fd, SG_NEXT_CMD_LEN, &(int){ 17 });
write(fd, buf, sizeof(buf));
}
The crash was:

commit f44cb4b19ed40b655c2d422c9021ab2c2625adb6 upstream.
The Atheros 1525/QCA6174 BT doesn't seem working properly on the
recent kernels, as it tries to load a wrong firmware
ar3k/AthrBT_0x00000200.dfu and it fails.
This seems to have been a problem for some time, and the known
workaround is to apply BTUSB_QCA_ROM quirk instead of BTUSB_ATH3012.

resume quirk is still needed for this system.

commit f0e8c61110c2c85903b136ba070daf643a8b6842 upstream.
Commit 1fdb92697469 ("Bluetooth: btusb: Use DMI matching for QCA
reset_resume quirking"), added the Lenovo Yoga 920 to the
btusb_needs_reset_resume_table.
Testing has shown that this is a false positive and the problems where
caused by issues with the initial fix: commit fd865802c66b ("Bluetooth:
btusb: fix QCA Rome suspend/resume"), which has already been reverted.
So the QCA Rome BT in the Yoga 920 does not need a reset-resume quirk at
all and this commit removes it from the btusb_needs_reset_resume_table.
Note that after this commit the btusb_needs_reset_resume_table is now
empty. It is kept around on purpose, since this whole series of commits
started for a reason and there are actually broken platforms around,
which need to be added to it.

commit 93b0beae721b3344923b4b8317e9d83b542f4ca6 upstream.
Driver uses alias from Device Tree as an index of pin controller data
array. In case of a wrong DTB or an out-of-tree DTB, the alias could be
outside of this data array leading to out-of-bounds access.
Depending on binary and memory layout, this could be handled properly
(showing error like "samsung-pinctrl 3860000.pinctrl: driver data not
available") or could lead to exceptions.

commit 655296c8bbeffcf020558c4455305d597a73bde1 upstream.
Fix bugs in signaling the Hyper-V host when freeing space in the
host->guest ring buffer:
1. The interrupt_mask must not be used to determine whether to signal
on the host->guest ring buffer
2. The ring buffer write_index must be read (via hv_get_bytes_to_write)
*after* pending_send_sz is read in order to avoid a race condition
3. Comparisons with pending_send_sz must treat the "equals" case as
not-enough-space
4. Don't signal if the pending_send_sz feature is not present. Older
versions of Hyper-V that don't implement this feature will poll.

There is not enough to simply change umem to point to NULL, because the

commit 5682e268350f9eccdbb04006605c1b7068a7b323 upstream.
When support for the A31/A31s CCU was first added, the clock ops for
the CLK_OUT_* clocks was set to the wrong type. The clocks are MP-type,
but the ops was set for div (M) clocks. This went unnoticed until now.
This was because while they are different clocks, their data structures
aligned in a way that ccu_div_ops would access the second ccu_div_internal
and ccu_mux_internal structures, which were valid, if not incorrect.
Furthermore, the use of these CLK_OUT_* was for feeding a precise 32.768
kHz clock signal to the WiFi chip. This was achievable by using the parent
with the same clock rate and no divider. So the incorrect divider setting
did not affect this usage.
Commit 946797aa3f08 ("clk: sunxi-ng: Support fixed post-dividers on MP
style clocks") added a new field to the ccu_mp structure, which broke
the aforementioned alignment. Now the system crashes as div_ops tries
to look up a nonexistent table.

commit 7997f3b2df751aab0b8e60149b226a32966c41ac upstream.
CM_PLLx and A2W_XOSC_CTRL registers are accessed by different clock
handlers and must be accessed with ->regs_lock held.
Update the sections where this protection is missing.

commit 49012d1bf5f78782d398adb984a080a88ba42965 upstream.
ana->maskX values are already '~'-ed in bcm2835_pll_set_rate(). Remove
the '~' in the definition to fix ANA setup.
Note that this commit fixes a long standing bug preventing one from
using an HDMI display if it's plugged after the FW has booted Linux.
This is because PLLH is used by the HDMI encoder to generate the pixel
clock.

commit 28b2182dad43f6f8fcbd167539a26714fd12bd64 upstream.
Like the Highpoint Rocketraid 642L and cards using a Marvel 88SE9235
controller in general, this RAID card also supports AHCI mode and short
of a custom driver, this is the only way to make it work under Linux.
Note that even though the card is called to 644L, it has a product-id
of 0x0645.

commit 1903be8222b7c278ca897c129ce477c1dd6403a8 upstream.
The Highpoint RocketRAID 644L uses a Marvel 88SE9235 controller, as with
other Marvel controllers this needs a function 1 DMA alias quirk.
Note the RocketRAID 642L uses the same Marvel 88SE9235 controller and
already is listed with a function 1 DMA alias quirk.
