[ Upstream commit 4050207485e47e00353e87f2fe2166083e282688 ]
The 258a:6a88 keyboard-dock shipped with the Prowise PT301 tablet is
likely another ITE based design. The controller die is directly bonded
to the PCB with a blob of black glue on top so there are no markings and
the 258a vendor-id used is unknown anywhere. But the keyboard has the
exact same hotkeys mapped to Fn+F1 - F10 as the other ITE8595 keyboard
I have *and* it has the same quirky behavior wrt the rfkill hotkey.
Either way as said this keyboard has the same quirk for its rfkill /
airplane mode hotkey as the ITE 8595 chip, it only sends a single release
event when pressed and released, it never sends a press event.
This commit adds the 258a:6a88 USB id to the hid-ite id-table, fixing
the rfkill key not working on this keyboard.

[ Upstream commit 614b1868a125a0ba24be08f3a7fa832ddcde6bca ]
We just changed the code so we apply bias disable on the correct
register but forgot to align the register calculation. The result
is that we apply the change on the correct register, but possibly
at the incorrect offset/bit
This went undetected because offsets tends to be the same between
REG_PULL and REG_PULLEN for a given pin the EE controller. This
is not true for the AO controller.

commit 01f54664a4db0d612de0ece8e0022f21f9374e9b upstream.
First, rename out_no_locality to out_locality for bailing out on
both tpm_cmd_ready() and tpm_request_locality() failure.
Second, ignore the return value of go_to_idle() as it may override
the return value of the actual tpm operation, the go_to_idle() error
will be caught on any consequent command.
Last, fix the wrong 'goto out', that jumped back instead of forward.

commit 3cc9ffbb1f51eb4320575a48e4805a8f52e0e26b upstream.
Add the missing adjustment of the month range on alarm reads from the
RTC, correcting an issue coming from commit 9c6dfed92c3e ("rtc: m41t80:
add alarm functionality"). The range is 1-12 for hardware and 0-11 for
`struct rtc_time', and is already correctly handled on alarm writes to
the RTC.
It was correct up until commit 48e9766726eb ("drivers/rtc/rtc-m41t80.c:

implementation of alarm support.

commit eafb27fa5283599ce6c5492ea18cf636a28222bb upstream.
Mediatek Preloader is a proprietary embedded boot loader for loading
Little Kernel and Linux into device DRAM.
This boot loader also handle firmware update. Mediatek Preloader will be
enumerated as a virtual COM port when the device is connected to Windows
or Linux OS via CDC-ACM class driver. When the USB enumeration has been
done, Mediatek Preloader will send out handshake command "READY" to PC
actively instead of waiting command from the download tool.
Since Linux 4.12, the commit "tty: reset termios state on device
registration" (93857edd9829e144acb6c7e72d593f6e01aead66) causes Mediatek
Preloader receiving some abnoraml command like "READYXX" as it sent.
This will be recognized as an incorrect response. The behavior change
also causes the download handshake fail. This change only affects
subsequent connects if the reconnected device happens to get the same minor
number.
By disabling the ECHO termios flag could avoid this problem. However, it
cannot be done by user space configuration when download tool open
/dev/ttyACM0. This is because the device running Mediatek Preloader will
send handshake command "READY" immediately once the CDC-ACM driver is
ready.
This patch wants to fix above problem by introducing "DISABLE_ECHO"
property in driver_info. When Mediatek Preloader is connected, the
CDC-ACM driver could disable ECHO flag in termios to avoid the problem.

commit 7172122be6a4712d699da4d261f92aa5ab3a78b8 upstream.
In crypto_alloc_context(), a DMA pool is allocated through dma_pool_alloc()
to hold the crypto context. The meta data of the DMA pool, including the
pool used for the allocation 'ndev->ctx_pool' and the base address of the
DMA pool used by the device 'dma', are then stored to the beginning of the
pool. These meta data are eventually used in crypto_free_context() to free
the DMA pool through dma_pool_free(). However, given that the DMA pool can
also be accessed by the device, a malicious device can modify these meta
data, especially when the device is controlled to deploy an attack. This
can cause an unexpected DMA pool free failure.
To avoid the above issue, this patch introduces a new structure
crypto_ctx_hdr and a new field chdr in the structure nitrox_crypto_ctx hold
the meta data information of the DMA pool after the allocation. Note that
the original structure ctx_hdr is not changed to ensure the compatibility.

commit 56c1723426d3cfd4723bfbfce531d7b38bae6266 upstream.
The IRQ handler bcm2835_spi_interrupt() first reads as much as possible
from the RX FIFO, then writes as much as possible to the TX FIFO.
Afterwards it decides whether the transfer is finished by checking if
the TX FIFO is empty.
If very few bytes were written to the TX FIFO, they may already have
been transmitted by the time the FIFO's emptiness is checked. As a
result, the transfer will be declared finished and the chip will be
reset without reading the corresponding received bytes from the RX FIFO.
The odds of this happening increase with a high clock frequency (such
that the TX FIFO drains quickly) and either passing "threadirqs" on the
command line or enabling CONFIG_PREEMPT_RT_BASE (such that the IRQ
handler may be preempted between filling the TX FIFO and checking its
emptiness).
Fix by instead checking whether rx_len has reached zero, which means
that the transfer has been received in full. This is also more
efficient as it avoids one bus read access per interrupt. Note that
bcm2835_spi_transfer_one_poll() likewise uses rx_len to determine
whether the transfer has finished.

commit dbc944115eed48af110646992893dc43321368d8 upstream.
If submission of a DMA TX transfer succeeds but submission of the
corresponding RX transfer does not, the BCM2835 SPI driver terminates
the TX transfer but neglects to reset the dma_pending flag to false.
Thus, if the next transfer uses interrupt mode (because it is shorter
than BCM2835_SPI_DMA_MIN_LENGTH) and runs into a timeout,
dmaengine_terminate_all() will be called both for TX (once more) and
for RX (which was never started in the first place). Fix it.

commit 81b1e6e6a8590a19257e37a1633bec098d499c57 upstream.
Since the addition of platform MSI support, there were two helpers
supposed to allocate/free IRQs for a device:
platform_msi_domain_alloc_irqs()
platform_msi_domain_free_irqs()
In these helpers, IRQ descriptors are allocated in the "alloc" routine
while they are freed in the "free" one.
Later, two other helpers have been added to handle IRQ domains on top
of MSI domains:
platform_msi_domain_alloc()
platform_msi_domain_free()
Seen from the outside, the logic is pretty close with the former
helpers and people used it with the same logic as before: a
platform_msi_domain_alloc() call should be balanced with a
platform_msi_domain_free() call. While this is probably what was
intended to do, the platform_msi_domain_free() does not remove/free
the IRQ descriptor(s) created/inserted in
platform_msi_domain_alloc().
One effect of such situation is that removing a module that requested
an IRQ will let one orphaned IRQ descriptor (with an allocated MSI
entry) in the device descriptors list. Next time the module will be
inserted back, one will observe that the allocation will happen twice
in the MSI domain, one time for the remaining descriptor, one time for
the new one. It also has the side effect to quickly overshoot the
maximum number of allocated MSI and then prevent any module requesting
an interrupt in the same domain to be inserted anymore.
This situation has been met with loops of insertion/removal of the
mvpp2.ko module (requesting 15 MSIs each time).

commit 102cd909635612c0be784a519651954a7924c786 upstream.
SIMCOM are reusing a single device ID for many (all of their?)
different modems, based on different chipsets and firmwares. Newer
Qualcomm chipset generations require setting DTR to wake the QMI
function. The SIM7600E modem is using such a chipset, making it
fail to work with this driver despite the device ID match.
Fix by unconditionally enabling the SET_DTR quirk for all SIMCOM
modems using this specific device ID. This is similar to what
we already have done for another case of device IDs recycled over
multiple chipset generations: 14cf4a771b30 ("drivers: net: usb:
qmi_wwan: add QMI_QUIRK_SET_DTR for Telit PID 0x1201")
Initial testing on an older SIM7100 modem shows no immediate side
effects.

r8a66597_endpoint_disable()
commit c85400f886e3d41e69966470879f635a2b50084c upstream.
The function r8a66597_endpoint_disable() and r8a66597_urb_enqueue() may
be concurrently executed.
The two functions both access a possible shared variable "hep->hcpriv".
This shared variable is freed by r8a66597_endpoint_disable() via the
call path:
r8a66597_endpoint_disable
kfree(hep->hcpriv) (line 1995 in Linux-4.19)
This variable is read by r8a66597_urb_enqueue() via the call path:
r8a66597_urb_enqueue
spin_lock_irqsave(&r8a66597->lock)
init_pipe_info
enable_r8a66597_pipe
pipe = hep->hcpriv (line 802 in Linux-4.19)
The read operation is protected by a spinlock, but the free operation
is not protected by this spinlock, thus a concurrency use-after-free bug
may occur.
To fix this bug, the spin-lock and spin-unlock function calls in
r8a66597_endpoint_disable() are moved to protect the free operation.

The problem is that _memcpy_toio/_memcpy_fromio are not available on
that platform, and we have to prevent building the driver there.
In case we want to backport this to older kernels: between linux-4.8

but had the same problem.

[ Upstream commit cf0b70e71b32137ccf9c1f3dd9fb30cbf89b4322 ]
During the firmware flash process, some of the EMADs get timed out, which
causes the driver to send them again with a limit of 5 retries. There are
some situations in which 5 retries is not enough and the EMAD access fails.
If the failed EMAD was related to the flashing process, the driver fails
the flashing.
The reason for these timeouts during firmware flashing is cache misses in
the CPU running the firmware. In case the CPU needs to fetch instructions
from the flash when a firmware is flashed, it needs to wait for the
flashing to complete. Since flashing takes time, it is possible for pending
EMADs to timeout.
Fix by increasing EMADs' timeout while flashing firmware.

[ Upstream commit 8742beb50f2db903d3b6d69ddd81d67ce9914453 ]
Even though the link is down before entering hibernation,
there is an issue that the network interface always links up after resuming
from hibernation.
If the link is still down before enabling the network interface,
and after resuming from hibernation, the phydev->state is forcibly set
to PHY_UP in mdio_bus_phy_restore(), and the link becomes up.
In suspend sequence, only if the PHY is attached, mdio_bus_phy_suspend()
calls phy_stop_machine(), and mdio_bus_phy_resume() calls
phy_start_machine().
In resume sequence, it's enough to do the same as mdio_bus_phy_resume()
because the state has been preserved.
This patch fixes the issue by calling phy_start_machine() in
mdio_bus_phy_restore() in the same way as mdio_bus_phy_resume().

normal code path of ibmveth_xmit_start() that was originally introduced by

fix missed the error path where dma_unmap_page is wrongly called on the

result a failure to DMA map any of the frags results in a dmesg warning

commit 505b5240329b922f21f91d5b5d1e535c805eca6d upstream.
nr is indirectly controlled by user-space, hence leading to a
potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/gpu/drm/drm_ioctl.c:805 drm_ioctl() warn: potential spectre issue 'dev->driver->ioctls' [r]
drivers/gpu/drm/drm_ioctl.c:810 drm_ioctl() warn: potential spectre issue 'drm_ioctls' [r] (local cap)
drivers/gpu/drm/drm_ioctl.c:892 drm_ioctl_flags() warn: potential spectre issue 'drm_ioctls' [r] (local cap)
Fix this by sanitizing nr before using it to index dev->driver->ioctls
and drm_ioctls.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

commit e59f5e08ece1060073d92c66ded52e1f2c43b5bb upstream.
Commit 78d3a92edbfb ("gpiolib-acpi: Register GpioInt ACPI event handlers
from a late_initcall") deferred the entire acpi_gpiochip_request_interrupt
call for each event resource.
This means it also delays the gpiochip_request_own_desc(..., "ACPI:Event")
call. This is a problem if some AML code reads the GPIO pin before we
run the deferred acpi_gpiochip_request_interrupt, because in that case
acpi_gpio_adr_space_handler() will already have called
gpiochip_request_own_desc(..., "ACPI:OpRegion") causing the call from
acpi_gpiochip_request_interrupt to fail with -EBUSY and we will fail to
register an event handler.
acpi_gpio_adr_space_handler is prepared for acpi_gpiochip_request_interrupt
already having claimed the pin, but the other way around does not work.
One example of a problem this causes, is the event handler for the OTG
ID pin on a Prowise PT301 tablet not registering, keeping the port stuck
in whatever mode it was in during boot and e.g. only allowing charging
after a reboot.
This commit fixes this by only deferring the request_irq call and the
initial run of edge-triggered IRQs instead of deferring all of
acpi_gpiochip_request_interrupt.

commit 0b479790684192ab7024ce6a621f93f6d0a64d92 upstream.
While booting with rootfs on MMC, the following warning is encountered
on OMAP4430:
omap-dma-engine 4a056000.dma-controller: DMA-API: mapping sg segment longer than device claims to support [len=69632] [max=65536]
This is because the DMA engine has a default maximum segment size of 64K
but HSMMC sets:
mmc->max_blk_size = 512; /* Block Length at max can be 1024 */
mmc->max_blk_count = 0xFFFF; /* No. of Blocks is 16 bits */
mmc->max_req_size = mmc->max_blk_size * mmc->max_blk_count;
mmc->max_seg_size = mmc->max_req_size;
which ends up telling the block layer that we support a maximum segment
size of 65535*512, which exceeds the advertised DMA engine capabilities.
Fix this by clamping the maximum segment size to the lower of the
maximum request size and of the DMA engine device used for either DMA
channel.

commit e3ae3401aa19432ee4943eb0bbc2ec704d07d793 upstream.
Some eMMCs from Micron have been reported to need ~800 ms timeout, while
enabling the CACHE ctrl after running sudden power failure tests. The
needed timeout is greater than what the card specifies as its generic CMD6
timeout, through the EXT_CSD register, hence the problem.
Normally we would introduce a card quirk to extend the timeout for these
specific Micron cards. However, due to the rather complicated debug process
needed to find out the error, let's simply use a minimum timeout of 1600ms,
the double of what has been reported, for all cards when enabling CACHE

commit ba9f39a785a9977e72233000711ef1eb48203551 upstream.
In commit 5320226a0512 ("mmc: core: Disable HPI for certain Hynix eMMC
cards"), then intent was to prevent HPI from being used for some eMMC
cards, which didn't properly support it. However, that went too far, as
even BKOPS and CACHE ctrl became prevented. Let's restore those parts and
allow BKOPS and CACHE ctrl even if HPI isn't supported.

commit a0741ba40a009f97c019ae7541dc61c1fdf41efb upstream.
During a re-initialization of the eMMC card, we may fail to re-enable HPI.
In these cases, that isn't properly reflected in the card->ext_csd.hpi_en
bit, as it keeps being set. This may cause following attempts to use HPI,
even if's not enabled. Let's fix this!
