ALSA: hda/realtek: Fix built-mic regression on other ASUS models
A few ASUS models use the ALC256_FIXUP_ASUS_HEADSET_MODE although they
have no built-in mic pin on NID 0x13, as found in the commit
c1732ede5e80 ("ALSA: hda/realtek - Fix headset and mic on several Asus
laptops with ALC256"). This was relatively harmless in the past as
NID 0x13 was assigned as the secondary mic. But since the fix for the
pin sort order, this pin became the primary one, hence user started
noticing the broken input, and we've fixed already for a few ASUS
models to switch to ALC256_FIXUP_ASUS_MIC_NO_PRESENCE.
This patch corrects the other ASUS models to use the right quirk entry
for fixing the built-in mic regression. Here we cover X541SA
(1043:12e0), X541UV (1043:12f0), Z550SA (1043:13bf0) and X555UB
(1043:1ccd).

ALSA: usb-audio: Fix duplicated name in MIDI substream names
The MIDI substream name string is constructed from the combination of
the card shortname (which is taken from USB iProduct) and the USB
iJack. The problem is that some devices put the product name to the
iJack field, too. For example, aplaymidi -l output on the Lanchkey MK
49 are like:
% aplaymidi -l
Port Client name Port name
44:0 Launchkey MK4 49 Launchkey MK4 49 Launchkey MK4
44:1 Launchkey MK4 49 Launchkey MK4 49 Launchkey MK4
where the actual iJack name can't be seen because it's truncated due
to the doubly words.
For resolving those situations, this patch compares the iJack string
with the card shortname, and drops if both start with the same words.
Then the result becomes like:
% aplaymidi -l
Port Client name Port name
40:0 Launchkey MK4 49 Launchkey MK4 49 MIDI In
40:1 Launchkey MK4 49 Launchkey MK4 49 DAW In
A caveat is that there are some pre-defined names for certain
devices in the driver code, and this workaround shouldn't be applied
to them. Similarly, when the iJack isn't specified, we should skip
this check, too. The patch added those checks in addition to the
string comparison.

ALSA: ump: Fix buffer overflow at UMP SysEx message conversion
The conversion function from MIDI 1.0 to UMP packet contains an
internal buffer to keep the incoming MIDI bytes, and its size is 4, as
it was supposed to be the max size for a MIDI1 UMP packet data.
However, the implementation overlooked that SysEx is handled in a
different format, and it can be up to 6 bytes, as found in
do_convert_to_ump(). It leads eventually to a buffer overflow, and
may corrupt the memory when a longer SysEx message is received.
The fix is simply to extend the buffer size to 6 to fit with the SysEx
UMP message.

firmware: cs_dsp: test_bin_error: Fix uninitialized data used as fw version
Call cs_dsp_mock_xm_header_get_fw_version() to get the firmware version

Make the same change to cs_dsp_bin_test_common_init() and remove the
cs_dsp_mock_xm_header_get_fw_version_from_regmap() function.
The code in cs_dsp_test_bin.c was correctly calling
cs_dsp_mock_xm_header_get_fw_version_from_regmap() to fetch the fw version
from a dummy header it wrote to XM registers. However in
cs_dsp_test_bin_error.c the test doesn't stuff a dummy header into XM, it
populates it the normal way using a wmfw file. It should have called
cs_dsp_mock_xm_header_get_fw_version() to get the data from its blob
buffer, but was calling cs_dsp_mock_xm_header_get_fw_version_from_regmap().
As nothing had been written to the registers this returned the value of
uninitialized data.
The only other use of cs_dsp_mock_xm_header_get_fw_version_from_regmap()
was cs_dsp_test_bin.c, but it doesn't need to use it. It already has a
blob buffer containing the dummy XM header so it can use
cs_dsp_mock_xm_header_get_fw_version() to read from that.

Commit
a42e988 ("ASoC: dwc: add DMA handshake control") changed the
behavior of the driver to not enable or disable i2s irqs if using DMA. This
breaks platforms such as AMD ACP. Audio playback appears to work but no
audio can be heard. Revert to the old behavior by always enabling and
disabling i2s irqs while keeping DMA handshake control.

Disable SLUB_TINY for build testing
... and don't error out so hard on missing module descriptions.
Before commit
6c6c1fc09de3 ("modpost: require a MODULE_DESCRIPTION()")
we used to warn about missing module descriptions, but only when
building with extra warnigns (ie 'W=1').
After that commit the warning became an unconditional hard error.
And it turns out not all modules have been converted despite the claims
to the contrary. As reported by Damian Tometzki, the slub KUnit test
didn't have a module description, and apparently nobody ever really
noticed.
The reason nobody noticed seems to be that the slub KUnit tests get
disabled by SLUB_TINY, which also ends up disabling a lot of other code,
both in tests and in slub itself. And so anybody doing full build tests
didn't actually see this failre.
So let's disable SLUB_TINY for build-only tests, since it clearly ends
up limiting build coverage. Also turn the missing module descriptions
error back into a warning, but let's keep it around for non-'W=1'
builds.

Both errors are caused by parse_cpu_str() reaching its limit of CPU_SUBSET_MAXCPUS.
It's a good idea to limit the maximum cpu number being parsed, but 1024 is too low.

in mainline because both architectures which enable that code have
hierarchical domains enabled. Though it breaks the ia64 build,
which enables the functionality, but does not have hierarchical
domains.

"A revert to fix a adjtimex() regression:
The recent change to prevent that time goes backwards for the coarse
time getters due to immediate multiplier adjustments via adjtimex(),
changed the way how the timekeeping core treats that.
That change result in a regression on the adjtimex() side, which is
user space visible:
1) The forwarding of the base time moves the update out of the
original period and establishes a new one. That's changing the
behaviour of the [PF]LL control, which user space expects to be
applied periodically.
2) The clearing of the accumulated NTP error due to #1, changes the
behaviour as well.
An attempt to delay the multiplier/frequency update to the next tick
did not solve the problem as userspace expects that the multiplier or
frequency updates are in effect, when the syscall returns.

kbuild: rpm-pkg: build a debuginfo RPM
The rpm-pkg make target currently suffers from a few issues related to
debuginfo:
1. debuginfo for things built into the kernel (vmlinux) is not available
in any RPM produced by make rpm-pkg. This makes using tools like
systemtap against a make rpm-pkg kernel impossible.
2. debug source for the kernel is not available. This means that
commands like 'disas /s' in gdb, which display source intermixed with
assembly, can only print file names/line numbers which then must be
painstakingly resolved to actual source in a separate editor.
3. debuginfo for modules is available, but it remains bundled with the
.ko files that contain module code, in the main kernel RPM. This is a
waste of space for users who do not need to debug the kernel (i.e.
most users).
Address all of these issues by additionally building a debuginfo RPM
when the kernel configuration allows for it, in line with standard
patterns followed by RPM distributors. With these changes:
1. systemtap now works (when these changes are backported to 6.11, since
systemtap lags a bit behind in compatibility), as verified by the
following simple test script:
# stap -e 'probe kernel.function("do_sys_open").call { printf("%s\n", $$parms); }'
dfd=0xffffffffffffff9c filename=0x7fe18800b160 flags=0x88800 mode=0x0
...

3. The size of the main kernel package goes down substantially,
especially if many modules are built (quite typical). Here is a
comparison of installed size of the kernel package (configured with
allmodconfig, dwarf4 debuginfo, and module compression turned off)
before and after this patch:
# rpm -qi kernel-6.13* | grep -E '^(Version|Size)'
Version : 6.13.0postpatch+
Size :
1382874089
Version : 6.13.0prepatch+
Size :
17870795887
This is a ~92% size reduction.
Note that a debuginfo package can only be produced if the following
configs are set:
- CONFIG_DEBUG_INFO=y
- CONFIG_MODULE_COMPRESS=n
- CONFIG_DEBUG_INFO_SPLIT=n
The first of these is obvious - we can't produce debuginfo if the build
does not generate it. The second two requirements can in principle be
removed, but doing so is difficult with the current approach, which uses
a generic rpmbuild script find-debuginfo.sh that processes all packaged
executables. If we want to remove those requirements the best path
forward is likely to add some debuginfo extraction/installation logic to
the modules_install target (controllable by flags). That way, it's
easier to operate on modules before they're compressed, and the logic
can be reused by all packaging targets.

kconfig: merge_config: use an empty file as initfile
The scripts/kconfig/merge_config.sh script requires an existing
$INITFILE (or the $1 argument) as a base file for merging Kconfig
fragments. However, an empty $INITFILE can serve as an initial starting
point, later referenced by the KCONFIG_ALLCONFIG Makefile variable
if -m is not used. This variable can point to any configuration file
containing preset config symbols (the merged output) as stated in
Documentation/kbuild/kconfig.rst. When -m is used $INITFILE will
contain just the merge output requiring the user to run make (i.e.
KCONFIG_ALLCONFIG=<$INITFILE> make <allnoconfig/alldefconfig> or make
olddefconfig).
Instead of failing when `$INITFILE` is missing, create an empty file and
use it as the starting point for merges.

sh: Align .bss section padding to 8-byte boundary
J2-based devices expect to find a device tree blob at the end of the
.bss section. As of
a77725a9a3c5 ("scripts/dtc: Update to upstream
version
v1.6.1-19-g0a3a9d3449c8"), libfdt enforces 8-byte alignment
for the DTB, causing J2 devices to fail early in sh_fdt_init().
As the J2 loader firmware calculates the DTB location based on the kernel
image .bss section size rather than the __bss_stop symbol offset, the
required alignment can't be enforced with BSS_SECTION(0, PAGE_SIZE, 8).
To fix this, inline a modified version of the above macro which grows
.bss by the required size. While this change affects all existing SH
boards, it should be benign on platforms which don't need this alignment.

Revert "timekeeping: Fix possible inconsistencies in _COARSE clockids"
This reverts commit
757b000f7b936edf79311ab0971fe465bbda75ea.
Miroslav reported that the changes for handling the inconsistencies in the
coarse time getters result in a regression on the adjtimex() side.
There are two issues:
1) The forwarding of the base time moves the update out of the original
period and establishes a new one.
2) The clearing of the accumulated NTP error is changing the behaviour as
well.
Userspace expects that multiplier/frequency updates are in effect, when the
syscall returns, so delaying the update to the next tick is not solving the
problem either.
Revert the change, so that the established expectations of user space
implementations (ntpd, chronyd) are restored. The re-introduced
inconsistency of the coarse time getters will be addressed in a subsequent
fix.

genirq/migration: Use irqd_get_parent_data() in irq_force_complete_move()
Frank reported, that the common irq_force_complete_move() breaks the out of
tree build of ia64. The reason is that ia64 uses the migration code, but
does not have hierarchical interrupt domains enabled.
This went unnoticed in mainline as both x86 and RISC-V have hierarchical
domains enabled. Not that it matters for mainline, but it's still
inconsistent.
Use irqd_get_parent_data() instead of accessing the parent_data field
directly. The helper returns NULL when hierarchical domains are disabled
otherwise it accesses the parent_data field of the domain.
No functional change.

While at it rename the queue ID variable to rxq_idx in

The XArray insertion is reordered after the netdev_rx_queue_restart()

net: ibmveth: make veth_pool_store stop hanging
v2:
- Created a single error handling unlock and exit in veth_pool_store
- Greatly expanded commit message with previous explanatory-only text
Summary: Use rtnl_mutex to synchronize veth_pool_store with itself,
ibmveth_close and ibmveth_open, preventing multiple calls in a row to

Background: Two (or more) threads could call veth_pool_store through
writing to /sys/devices/vio/
30000002/pool*/*. You can do this easily
with a little shell script. This causes a hang.

ibmveth_close calls napi_disable at the top and ibmveth_open calls
napi_enable at the top.
https://docs.kernel.org/networking/napi.html]] says
The control APIs are not idempotent. Control API calls are safe
against concurrent use of datapath APIs but an incorrect sequence of
control API calls may result in crashes, deadlocks, or race
conditions. For example, calling napi_disable() multiple times in a
row will deadlock.
In the normal open and close paths, rtnl_mutex is acquired to prevent
other callers. This is missing from veth_pool_store. Use rtnl_mutex in
veth_pool_store fixes these hangs.

ipv6: Do not consider link down nexthops in path selection
Nexthops whose link is down are not supposed to be considered during
path selection when the "ignore_routes_with_linkdown" sysctl is set.
This is done by assigning them a negative region boundary.
However, when comparing the computed hash (unsigned) with the region
boundary (signed), the negative region boundary is treated as unsigned,
resulting in incorrect nexthop selection.
Fix by treating the computed hash as signed. Note that the computed hash
is always in range of [0, 2^31 - 1].

ipv6: Start path selection from the first nexthop
Cited commit transitioned IPv6 path selection to use hash-threshold
instead of modulo-N. With hash-threshold, each nexthop is assigned a
region boundary in the multipath hash function's output space and a
nexthop is chosen if the calculated hash is smaller than the nexthop's
region boundary.
Hash-threshold does not work correctly if path selection does not start
with the first nexthop. For example, if fib6_select_path() is always
passed the last nexthop in the group, then it will always be chosen
because its region boundary covers the entire hash function's output
space.
Fix this by starting the selection process from the first nexthop and do
not consider nexthops for which rt6_score_route() provided a negative
score.

usbnet:fix NPE during rx_complete
Missing usbnet_going_away Check in Critical Path.
The usb_submit_urb function lacks a usbnet_going_away
validation, whereas __usbnet_queue_skb includes this check.
This inconsistency creates a race condition where:
A URB request may succeed, but the corresponding SKB data
fails to be queued.
Subsequent processes:
(e.g., rx_complete → defer_bh → __skb_unlink(skb, list))
attempt to access skb->next, triggering a NULL pointer
dereference (Kernel Panic).

net: octeontx2: Handle XDP_ABORTED and XDP invalid as XDP_DROP
In the current implementation octeontx2 manages XDP_ABORTED and XDP
