The options are needed for MTK desktop device to boot
and avoid adding CONFIG_ARCH_MEDIATEK to gki_defconfig.
The options are enabled as hidden because of dependency
on CONFIG_ARCH_MEDIATEK. Being selected from hidden
overrides the dependency.

This updates the proxy-exec logic in android16-6.12
which was added at v14, to be synced with the v18
series of the patchset.
v14 series:
https://github.com/johnstultz-work/linux-dev/commits/proxy-exec-v14-6.12
v18 series:
https://github.com/johnstultz-work/linux-dev/commits/proxy-exec-v18-6.12
Changes since v14:
* Improved naming consistency and using the guard macro where
appropriate
* Improved comments
* Build fixes for !CONFIG_SMP
* Fixes for when sched_proxy_exec() is disabled
* Renamed update_curr_se to update_se_times, as suggested by
Steven Rostedt.
* Use put_prev_set_next_task as suggested by K Prateek Nayak
* Try to rework find_proxy_task() locking to use guard and
proxy_deactivate_task() in the way Peter suggested.
* Simplified changes to enqueue_task_rt to match deadline's
logic, as pointed out by Peter
* Get rid of preserve_need_resched flag and rework per Peter's
suggestion
* Rework find_proxy_task() to use guard to cleanup the exit
gotos as Peter suggested.
* Reworked the forced return-migration from find_proxy_task to
use Peter’s dequeue+wakeup approach, which helps resolve the
cpuhotplug issues I had also seen, caused by the manual return
migration sending tasks to offline cpus.
* A number of improvements to the commit messages and comments
suggested by Juri Lelli and Peter Zijlstra
* Added missing logic to put_prev_task_dl as pointed out by
K Prateek Nayak
* Add lockdep_assert_held_once and drop the READ_ONCE in
__get_task_blocked_on(), as suggested by Juri Lelli
* Moved update_curr_task logic into update_curr_se to simplify
things
* Renamed update_se_times to update_se, as suggested by Peter
* Reworked logic to fix an issue Peter pointed out with thread
group accounting being done on the donor, rather than the
running execution context.
* Fixed typos caught by Metin Kaya
* Suleiman Souhlal noticed an inefficiency in that we evaluate
if the lock owner’s task_cpu() is the current cpu, before we
look to see if the lock owner is on_rq at all. With v17 this
would result in us proxy-migrating a donor to a remote cpu,
only to then realize the task wasn’t even on the runqueue,
and doing the sleeping owner enqueuing. Suleiman suggested
instead that we evaluate on_rq first, so we can immediately do
sleeping owner enqueueing. Then only if the owner is on a
runqueue do we proxy-migrate the donor (which requires the
more costly lock juggling). While not a huge logical change,
it did uncover other problems, which needed to be resolved.
* One issue found was there was a race where if
do_activate_blocked_waiter() from the sleeping owner wakeup
was delayed and the task had already been woken up elsewhere.
It’s possible if that task was running and called into
schedule() to be blocked, it would be dequeued from the
runqueue, but before we switched to the new task,
do_activate_blocked_waiter() might try to activate it on a
different cpu. Clearly the do_activate_blocked_waiter() needed
to check the task on_cpu value as well.
* I found that we still can hit wakeups that end up skipping the
BO_WAKING -> BO_RUNNALBE transition (causing find_proxy_task()
to end up spinning waiting for that transition), so I re-added
the logic to handle doing return migrations from
find_proxy_task() if we hit that case.
* Hupu suggested a tweak in ttwu_runnable() to evaluate
proxy_needs_return() slightly earlier.
* Kuyo Chang reported and isolated a fix for a problem with
__task_is_pushable() in the !sched_proxy_exec case, which was
folded into the “sched: Fix rt/dl load balancing via chain
level balance” patch
* Reworked some of the logic around releasing the rq->donor
reference on migrations, using rq->idle directly.
* Sueliman also pointed out that some added task_struct elements
were not being initialized in the init_task code path, so that
was good to fix.

commit 7129ea6e242b00938532537da41ddf5fa3e21471 upstream.
Starting with Rust 1.88.0 (expected 2025-06-26) [1][2], `rustc` may
introduce a new lint that catches unnecessary transmutes, e.g.:
error: unnecessary transmute
--> rust/uapi/uapi_generated.rs:23242:18
|
23242 | unsafe { ::core::mem::transmute(self._bitfield_1.get(0usize, 1u8) as u8) }
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: replace this with: `(self._bitfield_1.get(0usize, 1u8) as u8 == 1)`
|
= note: `-D unnecessary-transmutes` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(unnecessary_transmutes)]`
There are a lot of them (at least 300), but luckily they are all in
`bindgen`-generated code.
Thus clean all up by allowing it there.
Since unknown lints trigger a lint itself in older compilers, do it
conditionally so that we can keep the `unknown_lints` lint enabled.

Patch series "Use kmem_cache for memcg alloc", v3.
(willy tldr: "you've gone from allocating 8 objects per 32KiB to
allocating 13 objects per 32KiB, a 62% improvement in memory consumption"
[1])
The mem_cgroup_alloc function creates mem_cgroup struct and it's
associated structures including mem_cgroup_per_node. Through detailed
analysis on our test machine (Arm64, 16GB RAM, 6.6 kernel, 1 NUMA node,
memcgv2 with nokmem,nosocket,cgroup_disable=pressure), we can observe the
memory allocation for these structures using the following shell commands:
# Enable tracing
echo 1 > /sys/kernel/tracing/events/kmem/kmalloc/enable
echo 1 > /sys/kernel/tracing/tracing_on
cat /sys/kernel/tracing/trace_pipe | grep kmalloc | grep mem_cgroup
# Trigger allocation if cgroup subtree do not enable memcg
echo +memory > /sys/fs/cgroup/cgroup.subtree_control
Ftrace Output:
# mem_cgroup struct allocation
sh-6312 [000] ..... 58015.698365: kmalloc:
call_site=mem_cgroup_css_alloc+0xd8/0x5b4
ptr=000000003e4c3799 bytes_req=2312 bytes_alloc=4096
gfp_flags=GFP_KERNEL|__GFP_ZERO node=-1 accounted=false
# mem_cgroup_per_node allocation
sh-6312 [000] ..... 58015.698389: kmalloc:
call_site=mem_cgroup_css_alloc+0x1d8/0x5b4
ptr=00000000d798700c bytes_req=2896 bytes_alloc=4096
gfp_flags=GFP_KERNEL|__GFP_ZERO node=0 accounted=false
Key Observations:
1. Both structures use kmalloc with requested sizes between 2KB-4KB
2. Allocation alignment forces 4KB slab usage due to pre-defined sizes
(64B, 128B,..., 2KB, 4KB, 8KB)
3. Memory waste per memcg instance:
Base struct: 4096 - 2312 = 1784 bytes
Per-node struct: 4096 - 2896 = 1200 bytes
Total waste: 2984 bytes (1-node system)
NUMA scaling: (1200 + 8) * nr_node_ids bytes
So, it's a little waste.
This patchset introduces dedicated kmem_cache:
Patch2 - mem_cgroup kmem_cache - memcg_cachep
Patch3 - mem_cgroup_per_node kmem_cache - memcg_pn_cachep
The benefits of this change can be observed with the following tracing
commands:
# Enable tracing
echo 1 > /sys/kernel/tracing/events/kmem/kmem_cache_alloc/enable
echo 1 > /sys/kernel/tracing/tracing_on
cat /sys/kernel/tracing/trace_pipe | grep kmem_cache_alloc | grep mem_cgroup
# In another terminal:
echo +memory > /sys/fs/cgroup/cgroup.subtree_control
The output might now look like this:
# mem_cgroup struct allocation
sh-9827 [000] ..... 289.513598: kmem_cache_alloc:
call_site=mem_cgroup_css_alloc+0xbc/0x5d4 ptr=00000000695c1806
bytes_req=2312 bytes_alloc=2368 gfp_flags=GFP_KERNEL|__GFP_ZERO node=-1
accounted=false
# mem_cgroup_per_node allocation
sh-9827 [000] ..... 289.513602: kmem_cache_alloc:
call_site=mem_cgroup_css_alloc+0x1b8/0x5d4 ptr=000000002989e63a
bytes_req=2896 bytes_alloc=2944 gfp_flags=GFP_KERNEL|__GFP_ZERO node=0
accounted=false
This indicates that the `mem_cgroup` struct now requests 2312 bytes and is
allocated 2368 bytes, while `mem_cgroup_per_node` requests 2896 bytes and
is allocated 2944 bytes. The slight increase in allocated size is due to
`SLAB_HWCACHE_ALIGN` in the `kmem_cache`.
Without `SLAB_HWCACHE_ALIGN`, the allocation might appear as:
# mem_cgroup struct allocation
sh-9269 [003] ..... 80.396366: kmem_cache_alloc:
call_site=mem_cgroup_css_alloc+0xbc/0x5d4 ptr=000000005b12b475
bytes_req=2312 bytes_alloc=2312 gfp_flags=GFP_KERNEL|__GFP_ZERO node=-1
accounted=false
# mem_cgroup_per_node allocation
sh-9269 [003] ..... 80.396411: kmem_cache_alloc:
call_site=mem_cgroup_css_alloc+0x1b8/0x5d4 ptr=00000000f347adc6
bytes_req=2896 bytes_alloc=2896 gfp_flags=GFP_KERNEL|__GFP_ZERO node=0
accounted=false
While the `bytes_alloc` now matches the `bytes_req`, this patchset
defaults to using `SLAB_HWCACHE_ALIGN` as it is generally considered more
beneficial for performance. Please let me know if there are any issues or
if I've misunderstood anything.
This patchset also move mem_cgroup_init ahead of cgroup_init() due to
cgroup_init() will allocate root_mem_cgroup, but each initcall invoke
after cgroup_init, so if each kmem_cache do not prepare, we need testing
NULL before use it.
This patch (of 3):
When cgroup_init() creates root_mem_cgroup through css_alloc callback,
some critical resources might not be fully initialized, forcing later
operations to perform conditional checks for resource availability.
This patch move mem_cgroup_init() to address the init order, it invoke
before cgroup_init, so, compare to subsys_initcall, it can use to prepare
some key resources before root_mem_cgroup alloc.

commit e7607f7d6d81af71dcc5171278aadccc94d277cd upstream.
ld.lld prior to 21.0.0 does not support using the KEEP keyword within an
overlay description, which may be needed to avoid discarding necessary
sections within an overlay with '--gc-sections', which can be enabled
for the kernel via CONFIG_LD_DEAD_CODE_DATA_ELIMINATION.
Disallow CONFIG_LD_DEAD_CODE_DATA_ELIMINATION without support for KEEP
within OVERLAY and introduce a macro, OVERLAY_KEEP, that can be used to
conditionally add KEEP when it is properly supported to avoid breaking
old versions of ld.lld.

Originally init/Kconfig.gki was just excluded on 32-bit, which works
fine for allmodconfig builds, but breaks downstream boards trying to
build specific drivers modularly (in a 'mixed tree' configuration)
for 32-bit ARM with Kleaf. Replace the workaround with a new one.

commit 5daa0c35a1f0e7a6c3b8ba9cb721e7d1ace6e619 upstream.
The kernel cannot currently self-parse BTF containing Rust debug
information. pahole uses the language of the CU to determine whether to
filter out debug information when generating the BTF. When LTO is
enabled, Rust code can cross CU boundaries, resulting in Rust debug
information in CUs labeled as C. This results in a system which cannot
parse its own BTF.

Originally I've added memsize logic to track memblock memory allocated
at the obsolete_checksetup and do_early_param. That showed size with its
param name.
But nowadays we don't see that big memory allocation in that early
param. To simplify memsize code, let me remove related code. Some code
like memblock_memsize_free will be remained for the next commits.

result in memblock allocation. This patch tries to distinguish memblock
changes done at early param.
A region in memsize will be created with name as the param string. And
the region size will be updated during the param function.

This partially reverts commit 1cf1608b4a.
(https://android-review.googlesource.com/c/kernel/common/+/3216798
on android-mainline from before 6.12 branch)
We still need this to support XFRM on 32-bit userspace on aarch64,
the Android way to do this involves not doing compat translation.

This `depends on` currently causes KASAN builds to run with
CONFIG_RUST=n. However, the relevant fix has been backported and is
available in Android's prebuilt for rustc 1.82.0, thus update the
version requirement to match.

Previously, two things stopped Rust from using MODVERSIONS:
1. Rust symbols are occasionally too long to be represented in the
original versions table
2. Rust types cannot be properly hashed by the existing genksyms
approach because:
* Looking up type definitions in Rust is more complex than C
* Type layout is potentially dependent on the compiler in Rust,
not just the source type declaration.
CONFIG_EXTENDED_MODVERSIONS addresses the first point, and
CONFIG_GENDWARFKSYMS the second. If Rust wants to use MODVERSIONS, allow
it to do so by selecting both features.

Track the blocked-on relation for mutexes, to allow following this
relation at schedule time.
task
| blocked-on
v
mutex
| owner
v
task
Also add a blocked_on_state value so we can distinguish when a
task is blocked_on a mutex, but is either blocked, waking up, or
runnable (such that it can try to acquire the lock its blocked
on).
This avoids some of the subtle & racy games where the blocked_on
state gets cleared, only to have it re-added by the
mutex_lock_slowpath call when it tries to acquire the lock on
wakeup
Also add blocked_lock to the task_struct so we can safely
serialize the blocked-on state.
Finally add wrappers that are useful to provide correctness
checks. Folded in from a patch by:
Valentin Schneider <valentin.schneider@arm.com>
This all will be used for tracking blocked-task/mutex chains
with the prox-execution patch in a similar fashion to how
priority inheritance is done with rt_mutexes.

Bug: 306081722
---
v2:
* Fixed blocked_on tracking in error paths that was causing crashes
v4:
* Ensure we clear blocked_on when waking ww_mutexes to die or wound.
This is critical so we don't get circular blocked_on relationships
that can't be resolved.
v5:
* Fix potential bug where the skip_wait path might clear blocked_on
when that path never set it
* Slight tweaks to where we set blocked_on to make it consistent,
along with extra WARN_ON correctness checking
* Minor comment changes
v7:
* Minor commit message change suggested by Metin Kaya
* Fix WARN_ON conditionals in unlock path (as blocked_on might already
be cleared), found while looking at issue Metin Kaya raised.
* Minor tweaks to be consistent in what we do under the
blocked_on lock, also tweaked variable name to avoid confusion

[ Upstream commit e017671f534dd3f568db9e47b0583e853d2da9b5 ]
The initramfs filename field is defined in
Documentation/driver-api/early-userspace/buffer-format.rst as:
37 cpio_file := ALGN(4) + cpio_header + filename + "\0" + ALGN(4) + data
...
55 ============= ================== =========================
56 Field name Field size Meaning
57 ============= ================== =========================
...
70 c_namesize 8 bytes Length of filename, including final \0
When extracting an initramfs cpio archive, the kernel's do_name() path
handler assumes a zero-terminated path at @collected, passing it
directly to filp_open() / init_mkdir() / init_mknod().
If a specially crafted cpio entry carries a non-zero-terminated filename
and is followed by uninitialized memory, then a file may be created with
trailing characters that represent the uninitialized memory. The ability
to create an initramfs entry would imply already having full control of
the system, so the buffer overrun shouldn't be considered a security
vulnerability.
Append the output of the following bash script to an existing initramfs
and observe any created /initramfs_test_fname_overrunAA* path. E.g.
./reproducer.sh | gzip >> /myinitramfs
It's easiest to observe non-zero uninitialized memory when the output is
gzipped, as it'll overflow the heap allocated @out_buf in __gunzip(),
rather than the initrd_start+initrd_size block.

Symlink filename fields handled in do_symlink() won't overrun past the
data segment, due to the explicit zero-termination of the symlink
target.
Fix filename buffer overrun by aborting the initramfs FSM if any cpio
entry doesn't carry a zero-terminator at the expected (name_len - 1)
offset.

In certain audio use cases, scheduling RT threads on cores that
are handling softirqs can lead to glitches. Prevent this
behavior in cases where the softirq is likely to take a long
time. To avoid unnecessary migrations, the old behavior is
preserved for RCU, SCHED and TIMER irqs which are expected to be
relatively quick.

The HAVE_CFI_ICALL_NORMALIZE_INTEGERS option has some tricky conditions
when KASAN or GCOV are turned on, as in that case we need some clang and
rustc fixes [1][2] to avoid boot failures. The intent with the current
setup is that you should be able to override the check and turn on the
option if your clang/rustc has the fix. However, this override does not
work in practice. Thus, use the new RUSTC_LLVM_VERSION to correctly
implement the check for whether the fix is available.
Additionally, remove KASAN_HW_TAGS from the list of incompatible
options. The CFI_ICALL_NORMALIZE_INTEGERS option is incompatible with
KASAN because LLVM will emit some constructors when using KASAN that are
assigned incorrect CFI tags. These constructors are emitted due to use
of -fsanitize=kernel-address or -fsanitize=kernel-hwaddress that are
respectively passed when KASAN_GENERIC or KASAN_SW_TAGS are enabled.
However, the KASAN_HW_TAGS option relies on hardware support for MTE
instead and does not pass either flag. (Note also that KASAN_HW_TAGS
does not `select CONSTRUCTORS`.)

To reduce static memory allocated in the task_struct to accommodate
vendor data, the move to a dynamically sized task_struct is being made.
As part of this effort, add padding after the init_task structure.
This has to be done because init_task is statically allocated and hence
will not benefit from the dynamic addition of size to all task_structs.

There is a bug in the LLVM implementation of KASAN and GCOV that makes
these options incompatible with the CFI_ICALL_NORMALIZE_INTEGERS option.
The bug has already been fixed in llvm/clang [1] and rustc [2]. However,
Kconfig currently has no way to gate features on the LLVM version inside
rustc, so we cannot write down a precise `depends on` clause in this
case. Instead, a `def_bool` option is defined for whether
CFI_ICALL_NORMALIZE_INTEGERS is available, and its default value is set
to false when GCOV or KASAN are turned on. End users using a patched
clang/rustc can turn on the HAVE_CFI_ICALL_NORMALIZE_INTEGERS option
directly to override this.
An alternative solution is to inspect a binary created by clang or rustc
to see whether the faulty CFI tags are in the binary. This would be a
precise check, but it would involve hard-coding the *hashed* version of
the CFI tag. This is because there's no way to get clang or rustc to
output the unhased version of the CFI tag. Relying on the precise
hashing algorithm using by CFI seems too fragile, so I have not pursued
this option. Besides, this kind of hack is exactly what lead to the LLVM
bug in the first place.
If the CFI_ICALL_NORMALIZE_INTEGERS option is used without CONFIG_RUST,
then we actually can perform a precise check today: just compare the
clang version number. This works since clang and llvm are always updated
in lockstep. However, encoding this in Kconfig would give the
HAVE_CFI_ICALL_NORMALIZE_INTEGERS option a dependency on CONFIG_RUST,
which is not possible as the reverse dependency already exists.
HAVE_CFI_ICALL_NORMALIZE_INTEGERS is defined to be a `def_bool` instead
of `bool` to avoid asking end users whether they want to turn on the
option. Turning it on explicitly is something only experts should do, so
making it hard to do so is not an issue.
I added a `depends on CFI_CLANG` clause to the new Kconfig option. I'm
not sure whether that makes sense or not, but it doesn't seem to make a
big difference.
In a future kernel release, I would like to add a Kconfig option similar
to CLANG_VERSION/RUSTC_VERSION for inspecting the version of the LLVM
inside rustc. Once that feature lands, this logic will be replaced with
a precise version check. This check is not being introduced here to
avoid introducing a new _VERSION constant in a fix.

When enabling both KASAN and RETHUNK, objtool emits the following
warnings:
rust/core.o: warning: objtool: asan.module_ctor+0x13: 'naked' return found in MITIGATION_RETHUNK build
rust/core.o: warning: objtool: asan.module_dtor+0x13: 'naked' return found in MITIGATION_RETHUNK build
This is caused by the -Zfunction-return=thunk-extern flag in rustc not
informing LLVM about the mitigation at the module level (it does so at
the function level only currently, which covers most cases, but both
are required), which means that the KASAN functions asan.module_ctor
and asan.module_dtor are generated without the rethunk mitigation.
The other mitigations that we enabled for Rust (SLS, RETPOLINE) do not
have the same bug, as they're being applied through the target-feature
functionality instead.
This is being fixed for rustc 1.83.0, so update Kconfig to reject this
configuration on older compilers.

Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Support 'MITIGATION_{RETHUNK,RETPOLINE,SLS}' (which cleans up
objtool warnings), teach objtool about 'noreturn' Rust symbols and
mimic '___ADDRESSABLE()' for 'module_{init,exit}'. With that, we
should be objtool-warning-free, so enable it to run for all Rust
object files.
- KASAN (no 'SW_TAGS'), KCFI and shadow call sanitizer support.
- Support 'RUSTC_VERSION', including re-config and re-build on
change.
- Split helpers file into several files in a folder, to avoid
conflicts in it. Eventually those files will be moved to the right
places with the new build system. In addition, remove the need to
manually export the symbols defined there, reusing existing
machinery for that.
- Relax restriction on configurations with Rust + GCC plugins to just
the RANDSTRUCT plugin.
'kernel' crate:
- New 'list' module: doubly-linked linked list for use with reference
counted values, which is heavily used by the upcoming Rust Binder.
This includes 'ListArc' (a wrapper around 'Arc' that is guaranteed
unique for the given ID), 'AtomicTracker' (tracks whether a
'ListArc' exists using an atomic), 'ListLinks' (the prev/next
pointers for an item in a linked list), 'List' (the linked list
itself), 'Iter' (an iterator over a 'List'), 'Cursor' (a cursor
into a 'List' that allows to remove elements), 'ListArcField' (a
field exclusively owned by a 'ListArc'), as well as support for
heterogeneous lists.
- New 'rbtree' module: red-black tree abstractions used by the
upcoming Rust Binder.
This includes 'RBTree' (the red-black tree itself), 'RBTreeNode' (a
node), 'RBTreeNodeReservation' (a memory reservation for a node),
'Iter' and 'IterMut' (immutable and mutable iterators), 'Cursor'
(bidirectional cursor that allows to remove elements), as well as
an entry API similar to the Rust standard library one.
- 'init' module: add 'write_[pin_]init' methods and the
'InPlaceWrite' trait. Add the 'assert_pinned!' macro.
- 'sync' module: implement the 'InPlaceInit' trait for 'Arc' by
introducing an associated type in the trait.
- 'alloc' module: add 'drop_contents' method to 'BoxExt'.
- 'types' module: implement the 'ForeignOwnable' trait for
'Pin<Box<T>>' and improve the trait's documentation. In addition,
add the 'into_raw' method to the 'ARef' type.
- 'error' module: in preparation for the upcoming Rust support for
32-bit architectures, like arm, locally allow Clippy lint for
those.
Documentation:
- https://rust.docs.kernel.org has been announced, so link to it.
- Enable rustdoc's "jump to definition" feature, making its output a
bit closer to the experience in a cross-referencer.
- Debian Testing now also provides recent Rust releases (outside of
the freeze period), so add it to the list.
