The error message buffer overflow 'dc->links' 12 <= 12 suggests that the
code is trying to access an element of the dc->links array that is
beyond its bounds. In C, arrays are zero-indexed, so an array with 12
elements has valid indices from 0 to 11. Trying to access dc->links[12]
would be an attempt to access the 13th element of a 12-element array,
which is a buffer overflow.
To fix this, ensure that the loop does not go beyond the last valid
index when accessing dc->links[i + 1] by subtracting 1 from the loop
condition.
This would ensure that i + 1 is always a valid index in the array.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_dp_dpia_bw.c:208 get_host_router_total_dp_tunnel_bw() error: buffer overflow 'dc->links' 12 <= 12

Add a NULL check for the kzalloc call that allocates memory for
dummy_updates in the amdgpu_dm_atomic_commit_tail function. Previously,
if kzalloc failed to allocate memory and returned NULL, the code would
attempt to use the NULL pointer.
The fix is to check if kzalloc returns NULL, and if so, log an error
message and skip the rest of the current loop iteration with the
continue statement. This prevents the code from attempting to use the
NULL pointer.

syzbot has found a type mismatch between a USB pipe and the transfer
endpoint, which is triggered by the bcm5974 driver[1].
This driver expects the device to provide input interrupt endpoints and
if that is not the case, the driver registration should terminate.
Repros are available to reproduce this issue with a certain setup for
the dummy_hcd, leading to an interrupt/bulk mismatch which is caught in
the USB core after calling usb_submit_urb() with the following message:
"BOGUS urb xfer, pipe 1 != type 3"
Some other device drivers (like the appletouch driver bcm5974 is mainly
based on) provide some checking mechanism to make sure that an IN
interrupt endpoint is available. In this particular case the endpoint
addresses are provided by a config table, so the checking can be
targeted to the provided endpoints.
Add some basic checking to guarantee that the endpoints available match
the expected type for both the trackpad and button endpoints.
This issue was only found for the trackpad endpoint, but the checking
has been added to the button endpoint as well for the same reasons.
Given that there was never a check for the endpoint type, this bug has
been there since the first implementation of the driver (f89bd95c5c94).

A last minute revert in 6.7-final introduced a potential deadlock when

The deadlock can easily be reproduced on machines like the Lenovo ThinkPad

probe where another thread can take a write lock.
Add a new pci_set_power_state_locked() and associated helper functions that
can be called with the PCI bus semaphore held to avoid taking the read lock
twice.

Geert Uytterhoeven reported that commit 4e244c10eab3 ("kconfig: remove
unneeded symbol_empty variable") changed the default value of
CONFIG_LOG_CPU_MAX_BUF_SHIFT from 12 to 0.
As it turned out, this is an undefined behavior because sym_calc_value()
stopped setting the sym->curr.tri field for 'int', 'hex', and 'string'
symbols.
This commit restores the original behavior, where 'int', 'hex', 'string'
symbols are interpreted as false if used in boolean contexts.
CONFIG_LOG_CPU_MAX_BUF_SHIFT will default to 12 again, irrespective
of CONFIG_BASE_SMALL. Presumably, this is not the intended behavior,
as already reported [1], but this is another issue that should be
addressed by a separate patch.

DMA buffers allocated from the CMA dma-buf heap get counted under
RssFile for processes that map them and trigger page faults. In
addition to the incorrect accounting reported to userspace, reclaim
behavior was influenced by the MM_FILEPAGES counter until linux 6.8, but
this memory is not reclaimable. [1] Change the CMA dma-buf heap to set
VM_PFNMAP on the VMA so MM does not poke at the memory managed by this
dma-buf heap, and use vmf_insert_pfn to correct the RSS accounting.
The system dma-buf heap does not suffer from this issue since
remap_pfn_range is used during the mmap of the buffer, which also sets
VM_PFNMAP on the VMA.

The new installkernel application that is now included in systemd-udev
package allows installation although destination files are already present
in the boot directory of the kernel package, but is failing with the
implemented workaround for the old installkernel application from grubby
package.
For the new installkernel application, as Davide says:
<<The %post currently does a shuffling dance before calling installkernel.
This isn't actually necessary afaict, and the current implementation
ends up triggering downstream issues such as
https://github.com/systemd/systemd/issues/29568
This commit simplifies the logic to remove the shuffling. For reference,
the original logic was added in commit 3c9c7a14b627("rpm-pkg: add %post
section to create initramfs and grub hooks").>>
But we need to keep the old behavior as well, because the old installkernel
application from grubby package, does not allow this simplification and
we need to be backward compatible to avoid issues with the different
packages.
Mimic Fedora shipping process and store vmlinuz, config amd System.map
in the module directory instead of the boot directory. In this way, we will
avoid the commented problem for all the cases, because the new destination
files are not going to exist in the boot directory of the kernel package.
Replace installkernel tool with kernel-install tool, because the latter is
more complete.
Besides, after installkernel tool execution, check to complete if the
correct package files vmlinuz, System.map and config files are present
in /boot directory, and if necessary, copy manually for install operation.
In this way, take into account if files were not previously copied from
/usr/lib/kernel/install.d/* scripts and if the suitable files for the
requested package are present (it could be others if the rpm files were
replace with a new pacakge with the same release and a different build).
Tested with Fedora 38, Fedora 39, RHEL 9, Oracle Linux 9.3,
openSUSE Tumbleweed and openMandrive ROME, using dnf/zypper and rpm tools.

Nathan's research indicates that Darwin seems to support weak aliases
at least [1]. Although the situation might be improved in future Clang
versions, we can achieve a similar outcome without relying on it.
This commit makes fatal() a macro of error() + exit(1) in modpost.h, as

There currently exists two thinkpad headset jack fixups:
ALC285_FIXUP_THINKPAD_NO_BASS_SPK_HEADSET_JACK
ALC285_FIXUP_THINKPAD_HEADSET_JACK
The latter is applied to alc285 and alc287 thinkpads which contain
bass speakers.
However, the former was only being applied to alc285 thinkpads,
leaving non-bass alc287 thinkpads with no headset button controls.

When using hotplug and bringing up a 32-bit CPU, ask the firmware about the
BTLB information to set up the static (block) TLB entries.
For that write access to the static btlb_info struct is needed, but
since it is marked __ro_after_init the kernel segfaults with missing
write permissions.
Fix the crash by dropping the __ro_after_init annotation.

ASMedia have confirmed that all ASM106x parts currently listed in
ahci_pci_tbl[] suffer from the 43-bit DMA address limitation that we ran
into on the ASM1061, and therefore, we need to apply the quirk added by
commit 20730e9b2778 ("ahci: add 43-bit DMA address quirk for ASMedia
ASM1061 controllers") to the other supported ASM106x parts as well.

Follow the docs at Documentation/bpf/kfuncs.rst:
- declare the function with `__bpf_kfunc`
- disables missing prototype warnings, which allows to remove them from
include/linux/hid-bpf.h
Removing the prototypes is not an issue because we currently have to
redeclare them when writing the BPF program. They will eventually be
generated by bpftool directly AFAIU.

Turns out that I got my reference counts wrong and each successful
bus_find_device() actually calls get_device(), and we need to manually
call put_device().
Ensure each bus_find_device() gets a matching put_device() when releasing
the bpf programs and fix all the error paths.

When the kfunc hid_bpf_attach_prog() is called, we called twice fdget():
one for fetching the type of the bpf program, and one for actually
attaching the program to the device.
The problem is that between those two calls, we have no guarantees that
the prog_fd is still the same file descriptor for the given program.
Solve this by calling bpf_prog_get() earlier, and use this to fetch the
program type.

The original idea of the delay_time check was to not apply multicast
snooping too early when an MLD querier appears. And to instead wait at
least for MLD reports to arrive before switching from flooding to group
based, MLD snooped forwarding, to avoid temporary packet loss.
However in a batman-adv mesh network it was noticed that after 248 days of
uptime 32bit MIPS based devices would start to signal that they had
stopped applying multicast snooping due to missing queriers - even though
they were the elected querier and still sending MLD queries themselves.
While time_is_before_jiffies() generally is safe against jiffies
wrap-arounds, like the code comments in jiffies.h explain, it won't
be able to track a difference larger than ULONG_MAX/2. With a 32bit
large jiffies and one jiffies tick every 10ms (CONFIG_HZ=100) on these MIPS
devices running OpenWrt this would result in a difference larger than
ULONG_MAX/2 after 248 (= 2^32/100/60/60/24/2) days and
time_is_before_jiffies() would then start to return false instead of
true. Leading to multicast snooping not being applied to multicast
packets anymore.
Fix this issue by using a proper timer_list object which won't have this
ULONG_MAX/2 difference limitation.

One of the test cases in the test_bridge_backup_port.sh selftest relies
on a matchall classifier to drop unrelated traffic so that the Tx drop
counter on the VXLAN device will only be incremented as a result of
traffic generated by the test.
However, the configuration option for the matchall classifier is
missing from the configuration file which might explain the failures we
see in the netdev CI [1].
Fix by adding CONFIG_NET_CLS_MATCHALL to the configuration file.

The Lenovo Legion Go is a handheld gaming system, similar to a Steam Deck.
It has a gamepad (including rear paddles), 3 gyroscopes, a trackpad,
volume buttons, a power button, and 2 LED ring lights.
The Legion Go firmware presents these controls as a USB hub with various
devices attached. In its default state, the gamepad is presented as an
Xbox controller connected to this hub. (By holding a combination of
buttons, it can be changed to use the older DirectInput API.)
This patch teaches the existing Xbox controller module `xpad` to bind to
the controller in the Legion Go, which enables support for the:
- directional pad,
- analog sticks (including clicks),
- X, Y, A, B,
- start and select (or menu and capture),
- shoulder buttons, and
- rumble.
The trackpad, touchscreen, volume controls, and power button are already
supported via existing kernel modules. Two of the face buttons, the
gyroscopes, rear paddles, and LEDs are not.
After this patch lands, the Legion Go will be mostly functional in Linux,
out-of-the-box. The various components of the USB hub can be synthesized
into a single logical controller (including the additional buttons) in
userspace with [Handheld Daemon](https://github.com/hhd-dev/hhd), which
makes the Go fully functional.

In an entirely unrelated discussion where I pointed out a stupid thinko
of mine, Rasmus piped up and noted that that obvious mistake already
existed elsewhere in the kernel tree.
An "error pointer" is the negative error value encoded as a pointer,
making the whole "return error or valid pointer" use-case simple and
straightforward. We use it all over the kernel.
But the key here is that errors are _negative_ error numbers, not the
horrid UNIX user-level model of "-1 and the value of 'errno'".
The Apple mailbox driver used the positive error values, and thus just
returned invalid normal pointers instead of actual errors.
Of course, the reason nobody ever noticed is that the errors presumably
never actually happen, so this is fixing a conceptual bug rather than an
actual one.

which means that the memory acquired in the atomic update needs to
not be invalidated by the cleanup. The buffer objects in vmw_plane_state
instead of using the builtin map_and_cache were trying to handle
the lifetime of the mapped memory themselves, leading to crashes.
