commit b76d26d69ecc97ebb24aaf40427a13c808a4f488 upstream.
There is no reason to assume that the IRQ rising edge (indicating that
the device start up phase is done) will happen after we request the IRQ.
If the device is already up by the time we request it, the call to
'wait_for_completion_timeout()' will timeout and we will fail the device
probe even though there's nothing wrong.
Fix it by just polling the status register until we get the indication that
the device is up and running. As a side effect of this fix, requesting the
IRQ is also moved to after the setup function.

commit 8b07e990fb254fcbaa919616ac77f981cb48c73d upstream.
The check mixes pages (vm_pgoff) with bytes (vm_start, vm_end) on one
side of the comparison, and uses resource address (rather than just the
resource size) on the other side of the comparison.
This can allow malicious userspace to easily bypass the boundary check and
map pages that are located outside memory-region reserved by the driver.

commit a89f355e469dcda129c2522be4fdba00c1c74c83 upstream.
In "qmp_cooling_devices_register", the count value is initially
QMP_NUM_COOLING_RESOURCES, which is 2. Based on the initial count value,
the memory for cooling_devs is allocated. Then while calling the
"qmp_cooling_device_add" function, count value is post-incremented for
each child node.
This makes the out of bound access to the cooling_dev array. Fix it by
passing the QMP_NUM_COOLING_RESOURCES definition to devm_kzalloc() and
initializing the count to 0.
While at it, let's also free the memory allocated to cooling_dev if no
cooling device is found in DT and during unroll phase.

commit 1b73e588f47397dee6e4bdfd953e0306c60b5fe5 upstream.
Casting a small array of u8 to an unsigned long is *never* OK:
- it does funny thing when the array size is less than that of a long,
as it accesses random places in the stack
- it makes everything even more fun with a BE kernel
Fix this by building the unsigned long used as a bitmap byte by byte,
in a way that works across endianess and has no undefined behaviours.
An extra BUILD_BUG_ON() catches the unlikely case where the array
would be larger than a single unsigned long.

commit 1a519dc7a73c977547d8b5108d98c6e769c89f4b upstream.
When running as Xen PV guest, masking MSI-X is a responsibility of the
hypervisor. The guest has no write access to the relevant BAR at all - when
it tries to, it results in a crash like this:

(...)
The recently introduced function msix_mask_all() does not check the global

of MSI[-X] interrupts.
Add the check to make this function XEN PV compatible.

array, which is required by the loop in the driver:
/* Count, allocate, and register clock muxes */
for (n = 0; desc[n].name;)
n++;
Here n will go out of bounds and then call clk_register_mux() on random
memory contents after the mux clock.
Fix this by terminating the array with a blank entry.

commit 79fad92f2e596f5a8dd085788a24f540263ef887 upstream.
Currently there are (at least) two problems in the way pwm_bl starts
managing the enable_gpio pin. Both occur when the backlight is initially
off and the driver finds the pin not already in output mode and, as a
result, unconditionally switches it to output-mode and asserts the signal.
Problem 1: This could cause the backlight to flicker since, at this stage
in driver initialisation, we have no idea what the PWM and regulator are
doing (an unconfigured PWM could easily "rest" at 100% duty cycle).
Problem 2: This will cause us not to correctly honour the
post_pwm_on_delay (which also risks flickers).
Fix this by moving the code to configure the GPIO output mode until after
we have examines the handover state. That allows us to initialize
enable_gpio to off if the backlight is currently off and on if the
backlight is on.

vga16fb_check_var() is failing to detect multiplication overflow.
if (vxres * vyres > maxmem) {

overflow happens, let's reject in the common path.

commit bb2853a6a421a052268eee00fd5d3f6b3504b2b1 upstream.
The ops->receive_buf() may be accessed concurrently from these two
functions. If the driver flushes data to the line discipline
receive_buf() method while tiocsti() is waiting for the
ops->receive_buf() to finish its work, the data race will happen.
For example:
tty_ioctl |tty_ldisc_receive_buf
->tioctsi | ->tty_port_default_receive_buf
| ->tty_ldisc_receive_buf
->hci_uart_tty_receive | ->hci_uart_tty_receive
->h4_recv | ->h4_recv
In this case, the h4 receive buffer will be overwritten by the
latecomer, and we will lost the data.
Hence, change tioctsi() function to use the exclusive lock interface
from tty_buffer to avoid the data race.

While looking at it, there's another potential issue for those which should
be *registered* into driver core. If device_register() failed, we put
device once and freed bcma_device structures. In bcma_unregister_cores(),
they're treated as unregistered and we hit both UAF and double-free. That
smells not good and has also been fixed now.

[ Upstream commit b357d9717be7f95fde2c6c4650b186a995b71e59 ]
commit 3ba7f53f8bf1 ("ice: don't remove netdev->dev_addr from uc sync
list") introduced calls to netif_addr_lock_bh() and
netif_addr_unlock_bh() in the driver's ndo_set_mac() callback. This is
fine since the driver is updated the netdev's dev_addr, but since this
is a spinlock, the driver cannot sleep when the lock is held.
Unfortunately the functions to add/delete MAC filters depend on a mutex.
This was causing a trace with the lock debug kernel config options
enabled when changing the mac address via iproute.

[ Upstream commit 6f15a2a09cecb7a2faba4a75bbd101f6f962294b ]
If an error occurs after a successful 'clk_prepare_enable()' call, it must
be undone by a corresponding 'clk_disable_unprepare()' call.
This call is already present in the remove function.
Add this call in the error handling path and reorder the code so that the
'clk_prepare_enable()' call happens later in the function.
The goal is to have as much managed resources functions as possible
before the 'clk_prepare_enable()' call in order to keep the error handling
path simple.
While at it, remove the now unneeded 'clk' variable.

ehci_orion_drv_probe() did not account for possible errors of
clk_prepare_enable() that in particular could cause invocation of
clk_disable_unprepare() on clocks that were not prepared/enabled yet,

there were several patches fixing different issues with clocks in this
driver, they did not solve this problem.
Add handling of errors of clk_prepare_enable() in ehci_orion_drv_probe()
to avoid calls of clk_disable_unprepare() without previous successful
invocation of clk_prepare_enable().

Depending on the DMA driver being used, the struct dma_slave_config may
need to be initialized to zero for the unused data.
For example, we have three DMA drivers using src_port_window_size and

When adding the code to handle platform_get_irq*() errors in the commit
489447380a29 ("handle errors returned by platform_get_irq*()"), the
actual error code was enforced to be -ENXIO in the driver for some
strange reason. This didn't matter much until the deferred probing was
introduced -- which requires an actual error code to be propagated
upstream from the failure site.
While fixing this, also stop overriding the errors from request_irq() to
-EIO (done since the pre-git era).

[ Upstream commit d1f278da6b11585f05b2755adfc8851cbf14a1ec ]
When scsi_dispatch_cmd was moved to scsi_lib.c and made static, some
compilers (i.e., at least gcc 8.4.0) decided to compile this
inline. This is a problem for lkdtm.ko, which inserted a kprobe
on this function for the SCSI_DISPATCH_CMD crashpoint.
Move this crashpoint one function up the call chain to
scsi_queue_rq. Though this is also a static function, it should never be
inlined because it is assigned as a structure entry. Therefore,
kprobe_register should always be able to find it.

[ Upstream commit 1e7c57355a3bc617fc220234889e49fe722a6305 ]
When unbinding the firmware device we need to make sure it has no
consumers left. Otherwise we'd leave them with a firmware handle
pointing at freed memory.
Keep a reference count of all consumers and introduce rpi_firmware_put()
which will permit automatically decrease the reference count upon
unbinding consumer drivers.

[ Upstream commit 8d744da241b81f4211f4813b0d3c1981326fa9ca ]
The driver overrides the error codes returned by platform_get_irq() to
-ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the
error codes upstream.

[ Upstream commit cbfa6f33e3a685c329d78e06b0cf1dcb23c9d849 ]
Commit 0a0a66c984b3 ("clk: staging: Specify IOMEM dependency for Xilinx
Clocking Wizard driver") introduces a dependency on the non-existing config
IOMEM, which basically makes it impossible to include this driver into any
build. Fortunately, ./scripts/checkkconfigsymbols.py warns:
IOMEM
Referencing files: drivers/staging/clocking-wizard/Kconfig
The config for IOMEM support is called HAS_IOMEM. Correct this reference to
the intended config.

[ Upstream commit 0d45a1373e669880b8beaecc8765f44cb0241e47 ]
The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to request_threaded_irq() (which
takes *unsigned* IRQ #), causing it to fail with -EINVAL, overriding an
original error code. Stop calling request_threaded_irq() with the invalid
IRQ #s.
