[ Upstream commit eccd25136386a04ebf46a64f3a34e8e0fab6d9e1 ]
In ath11k_mac_op_hw_scan(), the return value of kzalloc() is directly
used in memcpy(), which may lead to a NULL pointer dereference on
failure of kzalloc().
Fix this bug by adding a check of arg.extraie.ptr.
This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.
Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.
Builds with CONFIG_ATH11K=m show no new warnings, and our static
analyzer no longer warns about this code.

since the comment in the device-tree says it should be at 0xfe0000.

Move the cs_setup delay to the end of spi_set_cs.
From include/linux/spi/spi.h:
* @cs_setup: delay to be introduced by the controller after CS is
asserted
The cs_setup delay needs to happen *after* CS is asserted, that is, at
the end of spi_set_cs, not at the beginning. Otherwise we're just
delaying before the SPI transaction starts at all, which isn't very
useful.
No drivers use this right now, but that is likely to change soon with an
upcoming Apple SPI HID transport driver.

Extra crypto manager auto test were crashing or failling due
to 2 reasons:
- block in a dead loop (dues to issues in cipher end process management)
- crash due to read/write unmapped memory (this crash was also reported
when using openssl afalg engine)
Rework interrupt management, interrupts are masked as soon as they are
no more used: if input buffer is fully consumed, "Input FIFO not full"
interrupt is masked and if output buffer is full, "Output FIFO not
empty" interrupt is masked.
And crypto request finish when input *and* outpout buffer are fully
read/write.
About the crash due to unmapped memory, using scatterwalk_copychunks()
that will map and copy each block fix the issue.
Using this api and copying full block will also fix unaligned data
access, avoid early copy of in/out buffer, and make useless the extra
alignment constraint.

IIUC, this deadlock cannot actually happen, because command event
processing (which calls mwifiex_process_sta_tx_pause()) is
sequentialized with TX packet processing (e.g.,

Expedited RCU grace periods invoke sync_rcu_exp_select_node_cpus(), which
takes two passes over the leaf rcu_node structure's CPUs. The first
pass gathers up the current CPU and CPUs that are in dynticks idle mode.
The workqueue will report a quiescent state on their behalf later.
The second pass sends IPIs to the rest of the CPUs, but excludes the
current CPU, incorrectly assuming it has been included in the first
pass's list of CPUs.
Unfortunately the current CPU may have changed between the first and
second pass, due to the fact that the various rcu_node structures'
->lock fields have been dropped, thus momentarily enabling preemption.
This means that if the second pass's CPU was not on the first pass's
list, it will be ignored completely. There will be no IPI sent to
it, and there will be no reporting of quiescent states on its behalf.
Unfortunately, the expedited grace period will nevertheless be waiting
for that CPU to report a quiescent state, but with that CPU having no
reason to believe that such a report is needed.
The result will be an expedited grace period stall.
Fix this by no longer excluding the current CPU from consideration during
the second pass.

On an imx6dl-pico-pi board with a QCA9377 SDIO chip, simply trying to
connect via ssh to another machine causes:

[ 55.919887] ath10k_sdio mmc1:0001:1: failed to push frame: -12
, leading to an ssh connection failure.
One user inspected the size of frames on Wireshark and reported
the followig:
"I was able to narrow the issue down to the mtu. If I set the mtu for
the wlan0 device to 1486 instead of 1500, the issue does not happen.
The size of frames that I see on Wireshark is exactly 1500 after
setting it to 1486."
Clearing the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE avoids the problem and
the ssh command works successfully after that.
Introduce a 'credit_size_workaround' field to ath10k_hw_params for
the QCA9377 SDIO, so that the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE
is not set in this case.
Tested with QCA9377 SDIO with firmware WLAN.TF.1.1.1-00061-QCATFSWPZ-1.

Commit e955f959ac52 ("media: si2157: Better check for running tuner in
init") completely broke the "warm" tuner detection of the si2157 driver
due to a simple endian error: The Si2157 CRYSTAL_TRIM property code is
0x0402 and needs to be transmitted LSB first. However, it was inserted
MSB first, causing the warm detection to always fail and spam the kernel
log with tuner initialization messages each time the DVB frontend
device was closed and reopened:
[ 312.215682] si2157 16-0060: found a 'Silicon Labs Si2157-A30'

Also, the reinitializations were observed disturb _other_ tuners on
multi-tuner cards such as the Hauppauge WinTV-QuadHD, leading to missed
or errored packets when one of the other DVB frontend devices on that
card was opened.
Fix the order of the property code bytes to make the warm detection work
again, also reducing the tuner initialization message in the kernel log
to once per power-on, as well as fixing the interference with other
tuners.

API headers from libbpf should not be accessed directly from the source
directory. Instead, they should be exported with "make install_headers".
Make sure that samples/bpf/Makefile installs the headers properly when
building.
The object compiled from and exported by libbpf are now placed into a
subdirectory of sample/bpf/ instead of remaining in tools/lib/bpf/. We
attempt to remove this directory on "make clean". However, the "clean"
target re-enters the samples/bpf/ directory from the root of the
repository ("$(MAKE) -C ../../ M=$(CURDIR) clean"), in such a way that
$(srctree) and $(src) are not defined, making it impossible to use
$(LIBBPF_OUTPUT) and $(LIBBPF_DESTDIR) in the recipe. So we only attempt
to clean $(CURDIR)/libbpf, which is the default value.
Add a dependency on libbpf's headers for the $(TRACE_HELPERS).
We also change the output directory for bpftool, to place the generated
objects under samples/bpf/bpftool/ instead of building in bpftool's
directory directly. Doing so, we make sure bpftool reuses the libbpf
library previously compiled and installed.

Branch data available to BPF programs can be very useful to get stack traces
out of userspace application.
Commit fff7b64355ea ("bpf: Add bpf_read_branch_records() helper") added BPF
support to capture branch records in x86. Enable this feature also for other
architectures as well by removing checks specific to x86.
If an architecture doesn't support branch records, bpf_read_branch_records()
still has appropriate checks and it will return an -EINVAL in that scenario.
Based on UAPI helper doc in include/uapi/linux/bpf.h, unsupported architectures
should return -ENOENT in such case. Hence, update the appropriate check to
return -ENOENT instead.

condition for this exit path is incomplete. A task can wake up from an

such scenario would spuriously trigger the special case described above.
Also, a recent change made the idle task like a regular per-CPU kthread,
hence making that situation more likely to happen
(is_per_cpu_kthread(swapper) being true now).
Checking for task context makes sure select_idle_sibling() will not

[ Upstream commit 561ae1d46a8ddcbc13162d5771f5ed6c8249e730 ]
btmtksdio have to rely on MMC_PM_KEEP_POWER in pm_flags to avoid that
SDIO power is being shut off during the device is in suspend. That fixes
the SDIO command fails to access the bus after the device is resumed.
