commit 9dd631fa99dc0a0dfbd191173bf355ba30ea786a upstream.
The driver reporting IEEE80211_TX_STAT_ACK is not being handled
correctly. The driver should only report on TSR_TMO flag is not
set indicating no transmission errors and when not IEEE80211_TX_CTL_NO_ACK
is being requested.

commit d579c43c82f093e63639151625b2139166c730fd upstream.
It appears that the drivers does not go into power save correctly the
NULL data packets are not being transmitted because it not enabled
in mac80211.
The driver needs to capture ieee80211_is_nullfunc headers and
copy the duration_id to it's own duration data header.

commit d971fdd3412f8342747778fb59b8803720ed82b1 upstream.
It appears that the driver still transmits in CTS protect mode even
though it is not enabled in mac80211.
That is both packet types PK_TYPE_11GA and PK_TYPE_11GB both use CTS protect.
The only difference between them GA does not use B rates.
Find if only B rate in GB or GA in protect mode otherwise transmit packets
as PK_TYPE_11A.

commit 4cc41cbce536876678b35e03c4a8a7bb72c78fa9 upstream.
Currently when the call to prism2sta_ifst fails a netdev_err error
is reported, error return variable result is set to -1 but the
function always returns 0 for success. Fix this by returning
the error value in variable result rather than 0.

commit 4d1356ac12f4d5180d0df345d85ff0ee42b89c72 upstream.
If the length of the socket buffer is 0xFFFFFFFF (max size for an
unsigned int), then payload_len becomes 0xFFFFFFF1 after subtracting 14
(ETH_HLEN). Then, mdp_len is set to payload_len + 16 (MDP_HDR_LEN)
which overflows and results in a value of 2. These values for
payload_len and mdp_len will pass current buffer size checks.
This patch checks if derived from skb->len sum may overflow.
The check is based on the following idea:
For any `unsigned V1, V2` and derived `unsigned SUM = V1 + V2`,
`V1 + V2` overflows iif `SUM < V1`.

commit 9fea3a40f6b07de977a2783270c8c3bc82544d45 upstream.
This patch fixes a regression on setting up asynchronous commands to use
external trigger sources when board-specific routing information is
missing.
`ni_find_device_routes()` (called via `ni_assign_device_routes()`) finds
the table of register values for the device family and the set of valid
routes for the specific board. If both are found,
`tables->route_values` is set to point to the table of register values
for the device family and `tables->valid_routes` is set to point to the
list of valid routes for the specific board. If either is not found,
both `tables->route_values` and `tables->valid_routes` are left set at
their initial null values (initialized by `ni_assign_device_routes()`)
and the function returns `-ENODATA`.
Returning an error results in some routing functionality being disabled.
Unfortunately, leaving `table->route_values` set to `NULL` also breaks
the setting up of asynchronous commands that are configured to use
external trigger sources. Calls to `ni_check_trigger_arg()` or
`ni_check_trigger_arg_roffs()` while checking the asynchronous command
set-up would result in a null pointer dereference if
`table->route_values` is `NULL`. The null pointer dereference is fixed
in another patch, but it now results in failure to set up the
asynchronous command. That is a regression from the behavior prior to
commit 347e244884c3 ("staging: comedi: tio: implement global tio/ctr
routing") and commit 56d0b826d39f ("staging: comedi: ni_mio_common:
implement new routing for TRIG_EXT").
Change `ni_find_device_routes()` to set `tables->route_values` and/or
`tables->valid_routes` to valid information even if the other one can
only be set to `NULL` due to missing information. The function will
still return an error in that case. This should result in
`tables->valid_routes` being valid for all currently supported device
families even if the board-specific routing information is missing.
That should be enough to fix the regression on setting up asynchronous
commands to use external triggers for boards with missing routing
information.
Fixes: 347e244884c3 ("staging: comedi: tio: implement global tio/ctr routing")
Fixes: 56d0b826d39f ("staging: comedi: ni_mio_common: implement new routing for TRIG_EXT").

commit 01e20b664f808a4f3048ca3f930911fd257209bd upstream.
In `ni_find_route_source()`, `tables->route_values` gets dereferenced.
However it is possible that `tables->route_values` is `NULL`, leading to
a null pointer dereference. `tables->route_values` will be `NULL` if
the call to `ni_assign_device_routes()` during board initialization
returned an error due to missing device family routing information or
missing board-specific routing information. For example, there is
currently no board-specific routing information provided for the
PCIe-6251 board and several other boards, so those are affected by this
bug.
The bug is triggered when `ni_find_route_source()` is called via
`ni_check_trigger_arg()` or `ni_check_trigger_arg_roffs()` when checking
the arguments for setting up asynchronous commands. Fix it by returning
`-EINVAL` if `tables->route_values` is `NULL`.
Even with this fix, setting up asynchronous commands to use external
trigger sources for boards with missing routing information will still
fail gracefully. Since `ni_find_route_source()` only depends on the
device family routing information, it would be better if that was made
available even if the board-specific routing information is missing.
That will be addressed by another patch.

commit a9d3a9cedc1330c720e0ddde1978a8e7771da5ab upstream.
The Advantech PCI-1713 has 32 analog input channels, but an incorrect
bit-mask in the definition of the `PCI171X_MUX_CHANH(x)` and
PCI171X_MUX_CHANL(x)` macros is causing channels 16 to 31 to be aliases
of channels 0 to 15. Change the bit-mask value from 0xf to 0xff to fix
it. Note that the channel numbers will have been range checked already,
so the bit-mask isn't really needed.

commit ab42b48f32d4c766420c3499ee9c0289b7028182 upstream.
The "auto-attach" handler function `gsc_hpdi_auto_attach()` calls
`dma_alloc_coherent()` in a loop to allocate some DMA data buffers, and
also calls it to allocate a buffer for a DMA descriptor chain. However,
it does not check the return value of any of these calls. Change
`gsc_hpdi_auto_attach()` to return `-ENOMEM` if any of these
`dma_alloc_coherent()` calls fail. This will result in the comedi core
calling the "detach" handler `gsc_hpdi_detach()` as part of the
clean-up, which will call `gsc_hpdi_free_dma()` to free any allocated
DMA coherent memory buffers.

[ Upstream commit a0219deefe9ee5006a28d48522f76b217d198c51 ]
devm_regulator_get may return an error but mipi_csis_phy_init misses
a check for it.
This may lead to problems when regulator_set_voltage uses the unchecked
pointer.
This patch adds a check for devm_regulator_get to avoid potential risk.

[ Upstream commit 06eff2150d4db991ca236f3d05a9dc0101475aea ]
We need to shift and mask values at different occasions to fill up
cedrus registers. This was done using macros that don't explicitly
treat arguments as unsigned, leading to possibly undefined behavior.
Introduce the SHIFT_AND_MASK_BITS macro and use it where possible.
In cases where it doesn't apply as-is, explicitly cast to unsigned
instead.
This macro should be moved to include/linux/bits.h eventually.

[ Upstream commit 228241944a48113470d3c3b46c88ba7fbe0a274b ]
Inside a nested 'else' block at the beginning of this function is a
call that assigns 'psta' to the return value of 'rtw_get_stainfo()'.
If 'rtw_get_stainfo()' returns NULL and the flow of control reaches
the 'else if' where 'psta' is dereferenced, then we will dereference
a NULL pointer.
Fix this by checking if 'psta' is not NULL before reading its
'psta->qos_option' data member.

commit 58c93a548b0248fad6437f8c8921f9b031c3892a upstream.
The picture order count table only makes sense for profiles
higher than Baseline. This is confirmed by the H.264 specification
(See 8.2.1 Decoding process for picture order count), which
clarifies how POC are used for features not present in Baseline.
"""
Picture order counts are used to determine initial picture orderings
for reference pictures in the decoding of B slices, to represent picture
order differences between frames or fields for motion vector derivation
in temporal direct mode, for implicit mode weighted prediction in B slices,
and for decoder conformance checking.
"""
As a side note, this change matches various vendors downstream codebases,
including ChromiumOS and IMX VPU libraries.

commit 658f9d9921d7e76af03f689b5f0ffde042b8bf5b upstream.
The setting of the motion vectors usage and the setting of motion
vectors address are currently done under different conditions.
When decoding pre-recorded videos, this results of leaving the motion
vectors address unset, resulting in faulty memory accesses. Fix it
by using the same condition everywhere, which matches the profiles
that support motion vectors.

Commit 953aaa1492c53 ("media: rockchip/vpu: Prepare things to support decoders")
changed the conditions under S_FMT was allowed for OUTPUT
CAPTURE buffers.
However, and according to the mem-to-mem stateless decoder specification,
in order to support dynamic resolution changes, S_FMT should be allowed
even if OUTPUT buffers have been allocated.
Relax decoder S_FMT restrictions on OUTPUT buffers, allowing a
resolution modification, provided the pixel format stays the same.
Tested on RK3288 platforms using ChromiumOS Video Decode/Encode
Accelerator Unittests.

commit 17a29fea086ba18b000d28439bd5cb4f2b0a527b upstream.
When building for a non-Cavium MIPS system with COMPILE_TEST=y, the
Octeon ethernet driver hits a number of issues due to use of macros
provided only for CONFIG_CAVIUM_OCTEON_SOC=y configurations. For
example:
drivers/staging/octeon/ethernet-rx.c:190:6: error:
'CONFIG_CAVIUM_OCTEON_CVMSEG_SIZE' undeclared (first use in this function)
drivers/staging/octeon/ethernet-rx.c:472:25: error:
'OCTEON_IRQ_WORKQ0' undeclared (first use in this function)
These come from various asm/ headers that a non-Octeon build will be
using a non-Octeon version of.
Fix this by using the octeon-stubs.h header for non-Cavium MIPS builds,
and only using the real asm/octeon/ headers when building a Cavium
Octeon kernel configuration.
This requires that octeon-stubs.h doesn't redefine XKPHYS_TO_PHYS, which
is defined for MIPS by asm/addrspace.h which is pulled in by many other
common asm/ headers.

commit b7aa39a2ed0112d07fc277ebd24a08a7b2368ab9 upstream.
The variable skb is released via kfree_skb() when the return value of
_rtl92e_tx is not zero. However, after that, skb is accessed again to
read its length, which may result in a use after free bug. This patch
fixes the bug by moving the release operation to where skb is never
used later.
