[ Upstream commit ff02ac6216 ]
MSM8916 was originally using the "qcom,q6v5-pil" compatible for the
MSS remoteproc. Later it was decided to use SoC-specific compatibles
instead, so "qcom,msm8916-mss-pil" is now the preferred compatible.
Commit 60a05ed059 ("arm64: dts: qcom: msm8916: Add MSM8916-specific
compatibles to SCM/MSS") updated the MSM8916 device tree to make use of
the new compatible but still kept the old "qcom,q6v5-pil" as fallback.
This is inconsistent with other SoCs and conflicts with the description
in the binding documentation (which says that only one compatible should
be present). Also, it has no functional advantage since older kernels
could not handle this DT anyway (e.g. "power-domains" in the MSS node is
only supported by kernels that also support "qcom,msm8916-mss-pil").
Make this consistent with other SoCs by using only the
"qcom,msm8916-mss-pil" compatible.

[ Upstream commit 8898c9748a ]
Qualcomm MSM8996 Pro is a variant of MSM8996 with higher frequencies
supported both on CPU and GPU. There are other minor hardware
differencies in the CPU and GPU regulators and bus fabrics.
However this results in significant differences between 8996 and 8996
Pro CPU OPP tables. Judging from msm-3.18 there are only few common
frequencies supported by both msm8996 and msm8996pro. Rather than
hacking the tables for msm8996, split msm8996pro support into a separate
file. Later this would allow having additional customizations for the
CBF, CPR, retulators, etc.

allowed or possible.

commit 5adedd4224 upstream.
Commit cd3bc044af ("KEYS: encrypted: Instantiate key with
user-provided decrypted data") added key instantiation with user
provided decrypted data. The user data is hex-ascii-encoded but was
just memcpy'ed to the binary buffer. Fix this to use hex2bin instead.
Old keys created from user provided decrypted data saved with "keyctl
pipe" are still valid, however if the key is recreated from decrypted
data the old key must be converted to the correct format. This can be
done with a small shell script, e.g.:
BROKENKEY=abcdefABCDEF1234567890aaaaaaaaaa
NEWKEY=$(echo -ne $BROKENKEY | xxd -p -c32)
keyctl add user masterkey "$(cat masterkey.bin)" @u
keyctl add encrypted testkey "new user:masterkey 32 $NEWKEY" @u
However, NEWKEY is still broken: If for BROKENKEY 32 bytes were
specified, a brute force attacker knowing the key properties would only
need to try at most 2^(16*8) keys, as if the key was only 16 bytes long.
The security issue is a result of the combination of limiting the input
range to hex-ascii and using memcpy() instead of hex2bin(). It could
have been fixed either by allowing binary input or using hex2bin() (and
doubling the ascii input key length). This patch implements the latter.
The corresponding test for the Linux Test Project ltp has also been
fixed (see link below).

This is because in scatterwalk_copychunks(), we attempted to write to
a buffer (@sign) that was allocated in the stack (vmalloc area) by
crypt_message() and thus accessing its remaining 8 (x2) bytes ended up
crossing a page boundary.
To simply fix it, we could just pass @sign kmalloc'd from
crypt_message() and then we're done. Luckily, we don't seem to pass
any other vmalloc'd buffers in smb_rqst::rq_iov...
Instead, let's map the correct pages and offsets from vmalloc buffers
as well in cifs_sg_set_buf() and then avoiding such oopses.

commit 12c6223fc1 upstream.
Using an InterTech DMG-02 dongle, the led remains on when the system goes
into standby mode. After wakeup, it's no longer possible to control the
led.
It turned out that the register settings to enable or disable the led were
not correct. They worked for some dongles like the Edimax V2 but not for
others like the InterTech DMG-02.
This patch fixes the register settings. Bit 3 in the led_cfg2 register
controls the led status, bit 5 must always be set to be able to control
the led, bit 6 has no influence on the led. Setting the mac_pinmux_cfg
register is not necessary.
These settings were tested with Edimax V2 and InterTech DMG-02.

memcg_write_event_control() accesses the dentry->d_name of the specified
control fd to route the write call. As a cgroup interface file can't be
renamed, it's safe to access d_name as long as the specified file is a
regular cgroup file. Also, as these cgroup interface files can't be
removed before the directory, it's safe to access the parent too.
Prior to 347c4a8747 ("memcg: remove cgroup_event->cft"), there was a
call to __file_cft() which verified that the specified file is a regular
cgroupfs file before further accesses. The cftype pointer returned from
__file_cft() was no longer necessary and the commit inadvertently dropped
the file type check with it allowing any file to slip through. With the
invarients broken, the d_name and parent accesses can now race against
renames and removals of arbitrary files and cause use-after-free's.
Fix the bug by resurrecting the file type check in __file_cft(). Now that
cgroupfs is implemented through kernfs, checking the file operations needs
to go through a layer of indirection. Instead, let's check the superblock
and dentry type.
