There are two problems with meson8b_devm_clk_prepare_enable(),
introduced in commit a54dc4a490 ("net: stmmac: dwmac-meson8b:
Make the clock enabling code re-usable"):
- It doesn't pass the clk argument, but instead always the
rgmii_tx_clk of the device.
- It silently ignores the return value of devm_add_action_or_reset().
The former didn't become an actual bug until another user showed up in
the next commit 9308c47640 ("net: stmmac: dwmac-meson8b: add support
for the RX delay configuration"). The latter means the callers could
end up with the clock not actually prepared/enabled.

If we're doing device replace on a zoned filesystem and discover in
scrub_enumerate_chunks() that we don't have to copy the block group it is
unlocked before it gets skipped.
But as the block group hasn't yet been locked before it leads to a locking
imbalance. To fix this simply remove the unlock.

This reverts commit 786672e9e1.
[BUG]
Since commit 786672e9e1 ("btrfs: scrub: use larger block size for data
extent scrub"), btrfs scrub no longer reports errors if the corruption
is not in the first sector of a STRIPE_LEN.
The following script can expose the problem:
mkfs.btrfs -f $dev
mount $dev $mnt
xfs_io -f -c "pwrite -S 0xff 0 8k" $mnt/foobar
umount $mnt
# 13631488 is the logical bytenr of above 8K extent
btrfs-map-logical -l 13631488 -b 4096 $dev
mirror 1 logical 13631488 physical 13631488 device /dev/test/scratch1
# Corrupt the 2nd sector of that extent
xfs_io -f -c "pwrite -S 0x00 13635584 4k" $dev
mount $dev $mnt
btrfs scrub start -B $mnt
scrub done for 54e63f9f-0c30-4c84-a33b-5c56014629b7
Scrub started: Mon Nov 7 07:18:27 2022
Status: finished
Duration: 0:00:00
Total to scrub: 536.00MiB
Rate: 0.00B/s
Error summary: no errors found <<<
[CAUSE]
That offending commit enlarges the data extent scrub size from sector
size to BTRFS_STRIPE_LEN, to avoid extra scrub_block to be allocated.
But unfortunately the data extent scrub is still heavily relying on the
fact that there is only one scrub_sector per scrub_block.
Thus it will only check the first sector, and ignoring the remaining
sectors.
Furthermore the error reporting is not able to handle multiple sectors
either.
[FIX]
For now just revert the offending commit.
The consequence is just extra memory usage during scrub.
We will need a proper change to make the remaining data scrub path to
handle multiple sectors before we enlarging the data scrub size.

Add ENOMEM among the error codes that don't print stack trace on
transaction abort. We've got several reports from syzbot that detects
stacks as errors but caused by limiting memory. As this is an artificial
condition we don't need to know where exactly the error happens, the
abort and error cleanup will continue like e.g. for EIO.
As the transaction aborts code needs to be inline in a lot of code, the
implementation cases about minimal bloat. The error codes are in a
separate function and the WARN uses the condition directly. This
increases the code size by 571 bytes on release build.
Alternatives considered: add -ENOMEM among the errors, this increases
size by 2340 bytes, various attempts to combine the WARN and helper
calls, increase by 700 or more bytes.

This can be triggered when we set devid to (u64)-1 by ioctl. In this
case, the match of devid will be skipped and the match of device may
succeed incorrectly.
Patch 562d7b1512 introduced this function which is used to match device.
This function contains two matching scenarios, we can distinguish them by
checking the value of args->missing rather than check whether args->devid

The conversion looks harmless, however the addr value is updated inside

for_each_vma_range() iterating over stuff outside the range we care
about. Fix this by storing the end value separately. Also fix the case
where the range doesn't intersect with any vma, or if the vma itself
doesn't extend the entire range, which must mean we have hole at the
end. Both should result in an error, as per the previous behaviour.

Currently we are observing mouse cursor stuttering when using
xrandr --scaling=1.2x1.2. X scaling/transformation seems to be
doing fronbuffer rendering. When moving mouse cursor X seems to
perform several invalidates and only one DirtyFB. I.e. it seems
to be assuming updates are sent to panel while drawing is done.
Earlier we were disabling PSR in frontbuffer invalidate call back
(when drawing in X started). PSR was re-enabled in frontbuffer
flush callback (dirtyfb ioctl). This was working fine with X
scaling/transformation. Now we are just enabling continuous full
frame (cff) in PSR invalidate callback. Enabling cff doesn't
trigger any updates. It just configures PSR to send full frame
when updates are sent. I.e. there are no updates on screen before
PSR flush callback is made. X seems to be doing several updates
in frontbuffer before doing dirtyfb ioctl.
Fix this by sending single update on every invalidate callback.

In commit a6d190f8c7 ("can: skb: drop tx skb if in listen only
mode") the priv->ctrlmode element is read even on virtual CAN
interfaces that do not create the struct can_priv at startup. This
out-of-bounds read may lead to CAN frame drops for virtual CAN
interfaces like vcan and vxcan.
This patch mainly reverts the original commit and adds a new helper
for CAN interface drivers that provide the required information in
struct can_priv.

In commit 4b7fe92c06 ("can: isotp: add local echo tx processing for
consecutive frames") the data flow for consecutive frames (CF) has been
reworked to improve the reliability of long data transfers.
This rework did not touch the transmission and the tx state changes of
single frame (SF) transfers which likely led to the WARN in the
isotp_tx_timer_handler() catching a wrong tx state. This patch makes use
of the improved frame processing for SF frames and sets the ISOTP_SENDING
state in isotp_sendmsg() within the cmpxchg() condition handling.
A review of the state machine and the timer handling additionally revealed
a missing echo timeout handling in the case of the burst mode in
isotp_rcv_echo() and removes a potential timer configuration uncertainty
in isotp_rcv_fc() when the receiver requests consecutive frames.
Fixes: 4b7fe92c06 ("can: isotp: add local echo tx processing for consecutive frames")

It causes NULL pointer dereference when testing as following:
(a) use syscall(__NR_socket, 0x10ul, 3ul, 0) to create netlink socket.
(b) use syscall(__NR_sendmsg, ...) to create bond link device and vxcan
link device, and bind vxcan device to bond device (can also use
ifenslave command to bind vxcan device to bond device).
(c) use syscall(__NR_socket, 0x1dul, 3ul, 1) to create CAN socket.
(d) use syscall(__NR_bind, ...) to bind the bond device to CAN socket.
The bond device invokes the can-raw protocol registration interface to
receive CAN packets. However, ml_priv is not allocated to the dev,
dev_rcv_lists is assigned to NULL in can_rx_register(). In this case,
it will occur the NULL pointer dereference issue.

We have accessing P2SB from a very few places for quite known hardware.
When a new SoC appears in intel-family.h it's not obvious that it needs
to be added to p2sb.c as well. Instead, provide default BDF and refactor
p2sb_get_devfn() to always succeed. If in the future we would need to
exclude something, we may add a list of unsupported IDs.

Wifi is soft blocked by checking rfkill. When unblocked manually,
after few seconds it would be soft blocked again. So I was suspecting
something triggered rfkill to soft block wifi. At the end it was
fixed by removing hp_wmi module.
The root cause is the way hp-wmi driver handles command 1B on
post-2009 BIOS. In pre-2009 BIOS, command 1Bh return 0x4 to indicate
that BIOS no longer controls the power for the wireless devices.

Changes in v2:
- Add a comment that this needs to be revisited when dynamic-mux
support gets added (suggested by: Daniel Dadap)
Testing has shown that there are quite a few laptop models which rely
on native backlight control and which do not support ACPI video bus
backlight control, causing __acpi_video_get_backlight_type() to return
vendor. Known Windows laptop models affected by this are:
Acer Aspire 1640
HP Compaq nc6120
IBM ThinkPad X40
System76 Starling Star1
and the following MacBook models are affected too:
Apple MacBook 2.1
Apple MacBook 4.1
Apple MacBook Pro 7.1
the list of affected Windows laptop models is likely just the top of
the iceberg. So for now lets undo the change to not register native
backlight class devices when __acpi_video_get_backlight_type() != native.
Since as part of the backlight-detect refactor the detection code now
relies on the GPU drivers calling acpi_video_backlight_use_native() to
learn that native backlight support is available we cannot just remove
the acpi_video_backlight_use_native() calls from the GPU drivers.
Instead modify acpi_video_backlight_use_native() to always return true
for now. This is meant as a temporary work-around, which will be removed
again when the heuristics from __acpi_video_get_backlight_type() have
been improved so that they will return native on affected models.

The warning is caused in the following steps:
1. a socket named socketA is created
2. socketA enters repair mode without build a connection
3. socketA calls connect() and its state is changed to TCP_ESTABLISHED
directly
4. socketA leaves repair mode
5. socketA calls sendmsg() to send data, packets_out and sack_outs(dup
ack receives) increase
6. socketA enters repair mode again
7. socketA calls setsockopt with TCPOPT_SACK_PERM to enable sack
8. retransmit timer expires, it calls tcp_timeout_mark_lost(), lost_out
increases
9. sack_outs + lost_out > packets_out triggers since lost_out and
sack_outs increase repeatly
In function tcp_timeout_mark_lost(), tp->sacked_out will be cleared if
Step7 not happen and the warning will not be triggered. As suggested by
Denis and Eric, TCP_REPAIR_OPTIONS should be prohibited if data was
already sent.

[ 420.333904] failed to register platform driver vc4_hvs_driver [vc4]: -16

The reason is that vc4_drm_register() returns platform_driver_register()

fails, it returns without unregistering all the vc4 drivers, resulting the
vc4 can never be installed later.
A simple call graph is shown as below:

platform_driver_register()

fixed microcode revisions checking quirk
- Update Icelake and Sapphire Rapids events constraints
- Use the standard energy unit for Sapphire Rapids in RAPL
- Fix the hw_breakpoint test to fail more graciously on !SMP configs

- Enforce that TDX guests are successfully loaded only on TDX hardware
where virtualization exception (#VE) delivery on kernel memory is
disabled because handling those in all possible cases is "essentially
impossible"
- Add the proper include to the syscall wrappers so that BTF can see the
real pt_regs definition and not only the forward declaration
