cgroup: Changes for v6.12
- cpuset isolation improvements. - cpuset cgroup1 support is split into its own file behind the new config option CONFIG_CPUSET_V1. This makes it the second controller which makes cgroup1 support optional after memcg. - Handling of unavailable v1 controller handling improved during cgroup1 mount operations. - union_find applied to cpuset. It makes code simpler and more efficient. - Reduce spurious events in pids.events. - Cleanups and other misc changes. - Contains a merge of cgroup/for-6.11-fixes to receive cpuset fixes that further changes build upon. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCZuNU3Q4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGdMsAP9yqPxu//LiJ3lPWhKcVVKtdwrA3AYDLE81VSJO 5VZJhAD+Ic+Ly/jZjDtjjQpZ1U3JsBpBRcVBqzeH0gD7eXaJgwk= =h/+c -----END PGP SIGNATURE----- Merge tag 'cgroup-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup updates from Tejun Heo: - cpuset isolation improvements - cpuset cgroup1 support is split into its own file behind the new config option CONFIG_CPUSET_V1.

tpm: Drop explicit initialization of struct i2c_device_id::driver_data to 0
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own.

tpm: Clean up TPM space after command failure
tpm_dev_transmit prepares the TPM space before attempting command
transmission. However if the command fails no rollback of this
preparation is done. This can result in transient handles being leaked
if the device is subsequently closed with no further commands performed.
Fix this by flushing the space in the event of command transmission
failure.

sound updates for 6.12-rc1
A fairly big update at this time, both in core and driver sides.
The core received rewrites in PCM buffer allocation handling and
locking optimizations, PCM rate updates followed by lots of cleanups.
In ASoC side, the legacy Intel drivers have been deprecated by AVS
drivers which leaded to the significant amount of code reduction.
SoundWire driver updates and other cleanups contributed more code
reduction, too.
USB-audio driver received a large cleanup of its big quirk table, and
the old snd_print*() API usages in many legacy drivers are replaced
with the standard print API.
Here are some highlights:
Core:
- More optimized locking in ALSA control code
- Rewrites of memalloc helpers for better DMA API usage
- Drop of obsoleted vmalloc PCM buffer helper API
- Continued MIDI2 UMP updates
- Support of a new user-space driven timer instance
- Update for more PCM support rates and cleanups
- Xrun counter report in the proc files
ASoC:
- Continued simplification and cleanup works for ASoC
- Extensive cleanups and refactoring of the Soundwire drivers
- Removal of Intel machine support obsoleted by the AVS driver
- Lots of DT schema conversions
- Machine support for many AMD and Intel x86 platforms
- Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320
SoundWire and rev C, and Texas Instruments TAS2563
USB-audio:
- Add support of multiple control interfaces
- A large rewrite of quirk table with macros
- Support for RME Digiface USB
HD-audio:
- Cleanup of quirk code for Samsung Galaxy laptops
- Clean up of detection of Cirrus codecs
- C-Media CM9825 HD-audio codec support
Others:
- Rewrites to standard print API in a lot of legacy drivers

Updates for x86 timers:
- Use the topology information of number of packages for making the
decision about TSC trust instead of using the number of online nodes
which is not reflecting the real topology.
- Stop the PIT timer 0 when its not in use as to stop pointless emulation
in the VMM.
- Fix the PIT timer stop sequence for timer 0 so it truly stops both real
hardware and buggy VMM emulations.

Pull x86 timer updates from Thomas Gleixner:
- Use the topology information of number of packages for making the
decision about TSC trust instead of using the number of online nodes
which is not reflecting the real topology.
- Stop the PIT timer 0 when its not in use as to stop pointless
emulation in the VMM.
- Fix the PIT timer stop sequence for timer 0 so it truly stops both
real hardware and buggy VMM emulations.

- Rework kcpuid to handle the the autogenerated CSV file correctly and
update the CSV file to cover the whole zoo of CPUID.

Updates for x86 memory management:
- Make LAM enablement safe vs. kernel threads using a process mm
temporarily as switching back to the process would not update CR3 and
therefore not enable LAM causing faults in user space when using tagged
pointers. Cure it by synchronizing LAM enablement via IPIs to all CPUs
which use the related mm.
- Cure a LAM harmless inconsistency between CR3 and the state during
context switch. It's both confusing and prone to lead to real bugs
- Handle alt stack handling for threads which run with a non-zero
protection key. The non-zero key prevents the kernel to access the
alternate stack. Cure it by temporarily enabling all protection keys for
the alternate stack setup/restore operations.
- Provide a EFI config table identity mapping for kexec kernel to prevent
kexec fails because the new kernel cannot access the config table array
- Use GB pages only when a full GB is mapped in the identity map as
otherwise the CPU can speculate into reserved areas after the end of
memory which causes malfunction on UV systems.
- Remove the noisy and pointless SRAT table dump during boot
- Use is_ioremap_addr() for iounmap() address range checks instead of
high_memory. is_ioremap_addr() is more precise.

Updates for x86 FRED:
- Enable FRED right after init_mem_mapping() because at that point the
early IDT fault handler is replaced by the real fault handler. The real
fault handler retrieves the faulting address from the stack frame and
not from CR2 when the FRED feature is set. But that obviously only
works when FRED is enabled in the CPU as well.
- Set SS to __KERNEL_DS when enabling FRED to prevent a corner case where
ERETS can observe a SS mismatch and raises a #GP.

powerpc/atomic: Use YZ constraints for DS-form instructions
The 'ld' and 'std' instructions require a 4-byte aligned displacement because they are DS-form instructions. But the "m" asm constraint doesn't enforce that. That can lead to build errors if the compiler chooses a non-aligned displacement, as seen with GCC 14: /tmp/ccuSzwiR.s: Assembler messages: /tmp/ccuSzwiR.s:2579: Error: operand out of domain (39 is not a multiple of 4) make[5]: *** [scripts/Makefile.build:229: net/core/page_pool.o] Error 1 Dumping the generated assembler shows: ld 8,39(8) # MEM[(const struct atomic64_t *)_29].counter, t Use the YZ constraints to tell the compiler either to generate a DS-form displacement, or use an X-form instruction, either of which prevents the build error.

Updates for the x86 APIC code:
- Handle an allocation failure in the IO/APIC code gracefully instead of
crashing the machine.
- Remove support for APIC local destination mode on 64bit
Logical destination mode of the local APIC is used for systems with up
to 8 CPUs. It has an advantage over physical destination mode as it
allows to target multiple CPUs at once with IPIs. That advantage was
definitely worth it when systems with up to 8 CPUs were state of the
art for servers and workstations, but that's history.
In the recent past there were quite some reports of new laptops failing
to boot with logical destination mode, but they work fine with physical
destination mode. That's not a suprise because physical destination
mode is guaranteed to work as it's the only way to get a CPU up and
running via the INIT/INIT/STARTUP sequence. Some of the affected
systems were cured by BIOS updates, but not all OEMs provide them.
As the number of CPUs keep increasing, logical destination mode becomes
less used and the benefit for small systems, like laptops, is not
really worth the trouble. So just remove logical destination mode
support for 64bit and be done with it.
- Code and comment cleanups in the APIC area.

Pull x86 APIC updates from Thomas Gleixner:
- Handle an allocation failure in the IO/APIC code gracefully instead
of crashing the machine.
- Remove support for APIC local destination mode on 64bit
Logical destination mode of the local APIC is used for systems with
up to 8 CPUs. It has an advantage over physical destination mode as
it allows to target multiple CPUs at once with IPIs. That advantage
was definitely worth it when systems with up to 8 CPUs were state of
the art for servers and workstations, but that's history.
In the recent past there were quite some reports of new laptops
failing to boot with logical destination mode, but they work fine
with physical destination mode. That's not a suprise because physical
destination mode is guaranteed to work as it's the only way to get a
CPU up and running via the INIT/INIT/STARTUP sequence. Some of the
affected systems were cured by BIOS updates, but not all OEMs provide
them.
As the number of CPUs keep increasing, logical destination mode
becomes less used and the benefit for small systems, like laptops, is
not really worth the trouble. So just remove logical destination mode
support for 64bit and be done with it.
- Code and comment cleanups in the APIC area.

soc: driver updates for 6.12
The driver updates seem larger this time around, with changes
is many of the SoC specific drivers, both the custom drivers/soc
ones and the closely related subsystems (memory, bus, firmware,
reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and
power management code. This is the latest variant of one of the
oldest still supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in many
of their drivers to add more features and additional SoC support. Most
of these are somewhat firmware related as the platform has a number of
firmware based interfaces to the kernel. A notable addition here is the
inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly cleanups.
The Arm SCMI firmware driver gets a major rework to modularize
the existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a
number of smaller updates.
The Arm FF-A firmware driver gets a feature update to support
the v1.2 version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring
for Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
mediatek) drivers and their DT bindings.

soc: devicetree updates for 6.12
New SoC support for Broadcom bcm2712 (Raspberry Pi 5) and Renesas
R9A09G057 (RZ/V2H(P)) and Qualcomm Snapdragon 414 (MSM8929), all three
of these are variants of already supported chips, in particular the last
one is almost identical to MSM8939.
Lots of updates to Mediatek, ASpeed, Rockchips, Amlogic, Qualcomm,
STM32, NXP i.MX, Sophgo, TI K3, Renesas, Microchip at91, NVIDIA Tegra,
and T-HEAD.
The added Qualcomm platform support once again dominates the changes,
with seven phones and three laptops getting added in addition to
many new features on existing machines. The Snapdragon X1E support
specifically keeps improving.
The other new machines are:
- eight new machines using various 64-bit Rockchips SoCs, both
on the consumer/gaming side and developer boards
- three industrial boards with 64-bit i.MX, which is a very
low number for them.
- four more servers using a 32-bit Speed BMC
- three boards using STM32MP1 SoCs
- one new machine each using allwinner, amlogic, broadcom
and renesas chips.

Pull SoC devicetree updates from Arnd Bergmann:
"New SoC support for Broadcom bcm2712 (Raspberry Pi 5) and Renesas
R9A09G057 (RZ/V2H(P)) and Qualcomm Snapdragon 414 (MSM8929), all three
of these are variants of already supported chips, in particular the
last one is almost identical to MSM8939.
Lots of updates to Mediatek, ASpeed, Rockchips, Amlogic, Qualcomm,
STM32, NXP i.MX, Sophgo, TI K3, Renesas, Microchip at91, NVIDIA Tegra,
and T-HEAD.
The added Qualcomm platform support once again dominates the changes,
with seven phones and three laptops getting added in addition to many
new features on existing machines. The Snapdragon X1E support
specifically keeps improving.
The other new machines are:
- eight new machines using various 64-bit Rockchips SoCs, both on the
consumer/gaming side and developer boards
- three industrial boards with 64-bit i.MX, which is a very low
number for them.
- four more servers using a 32-bit Speed BMC
- three boards using STM32MP1 SoCs
- one new machine each using allwinner, amlogic, broadcom and renesas
chips"

spi: Updates for v6.12
This is quite a quiet release for sPI. The one new core feature here is
support for configuring the state of the MOSI pin when the bus is idle,
there are some devices which are very fragile in this regard even when
the chip select signal is not asserted. Otherwise we have some new
driver support, a bunch of small fixes and some general cleanup work.
- Support for configuring the state of the MOSI pin when the the bus is
idle.
- Add the Elgin JG0309-01 in spidev.
- Support for Marvell xSPI, Mediatek MTK7981, Microchip PIC64GX,
NXP i.MX8ULP, and Rockchip RK3576 controllers.
I also accidentally pulled in an IIO DT bindings update due to a typo
when applying the MOSI idle state patches.

mm/hugetlb.c: fix UAF of vma in hugetlb fault pathway
Syzbot reports a UAF in hugetlb_fault(). This happens because
vmf_anon_prepare() could drop the per-VMA lock and allow the current VMA
to be freed before hugetlb_vma_unlock_read() is called.
We can fix this by using a modified version of vmf_anon_prepare() that
doesn't release the VMA lock on failure, and then release it ourselves
after hugetlb_vma_unlock_read().

Some callers of vmf_anon_prepare() may not want us to release the per-VMA

the callers drop the lock when desired.
Also, make vmf_anon_prepare() a wrapper that releases the per-VMA lock
itself for any callers that don't care.

resource: fix region_intersects() vs add_memory_driver_managed()
On a system with CXL memory, the resource tree (/proc/iomem) related to
CXL memory may look like something as follows.
490000000-50fffffff : CXL Window 0
490000000-50fffffff : region0
490000000-50fffffff : dax0.0
490000000-50fffffff : System RAM (kmem)
Because drivers/dax/kmem.c calls add_memory_driver_managed() during
onlining CXL memory, which makes "System RAM (kmem)" a descendant of "CXL
Window X". This confuses region_intersects(), which expects all "System
RAM" resources to be at the top level of iomem_resource. This can lead to
bugs.
For example, when the following command line is executed to write some
memory in CXL memory range via /dev/mem,
$ dd if=data of=/dev/mem bs=$((1 << 10)) seek=$((0x490000000 >> 10)) count=1
dd: error writing '/dev/mem': Bad address
1+0 records in
0+0 records out
0 bytes copied, 0.0283507 s, 0.0 kB/s
the command fails as expected. However, the error code is wrong. It
should be "Operation not permitted" instead of "Bad address". More
seriously, the /dev/mem permission checking in devmem_is_allowed() passes
incorrectly. Although the accessing is prevented later because ioremap()
isn't allowed to map system RAM, it is a potential security issue. During
command executing, the following warning is reported in the kernel log for
calling ioremap() on system RAM.
ioremap on RAM at 0x0000000490000000 - 0x0000000490000fff
WARNING: CPU: 2 PID: 416 at arch/x86/mm/ioremap.c:216 __ioremap_caller.constprop.0+0x131/0x35d
Call Trace:
memremap+0xcb/0x184
xlate_dev_mem_ptr+0x25/0x2f
write_mem+0x94/0xfb
vfs_write+0x128/0x26d
ksys_write+0xac/0xfe
do_syscall_64+0x9a/0xfd
entry_SYSCALL_64_after_hwframe+0x4b/0x53
The details of command execution process are as follows. In the above
resource tree, "System RAM" is a descendant of "CXL Window 0" instead of a
top level resource. So, region_intersects() will report no System RAM
resources in the CXL memory region incorrectly, because it only checks the
top level resources. Consequently, devmem_is_allowed() will return 1
(allow access via /dev/mem) for CXL memory region incorrectly.
Fortunately, ioremap() doesn't allow to map System RAM and reject the
access.
So, region_intersects() needs to be fixed to work correctly with the
resource tree with "System RAM" not at top level as above. To fix it, if
we found a unmatched resource in the top level, we will continue to search
matched resources in its descendant resources. So, we will not miss any
matched resources in resource tree anymore.
In the new implementation, an example resource tree
|------------- "CXL Window 0" ------------|
|-- "System RAM" --|
will behave similar as the following fake resource tree for
region_intersects(, IORESOURCE_SYSTEM_RAM, ),
|-- "System RAM" --||-- "CXL Window 0a" --|
Where "CXL Window 0a" is part of the original "CXL Window 0" that
isn't covered by "System RAM".

zsmalloc: use unique zsmalloc caches names
Each zsmalloc pool maintains several named kmem-caches for zs_handle-s and
zspage-s. On a system with multiple zsmalloc pools and CONFIG_DEBUG_VM
this triggers kmem_cache_sanity_check():
kmem_cache of name 'zspage' already exists

WARNING: at mm/slab_common.c:108 do_kmem_cache_create_usercopy+0xb5/0x310

We provide zram device name when init its zsmalloc pool, so we can use
that same name for zsmalloc caches and, hence, create unique names that
can easily be linked to zram device that has created them.
So instead of having this
cat /proc/slabinfo
slabinfo - version: 2.1
zspage 46 46 ...
zs_handle 128 128 ...
zspage 34270 34270 ...
zs_handle 34816 34816 ...
zspage 0 0 ...
zs_handle 0 0 ...
We now have this
cat /proc/slabinfo

Merge tag 'printk-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
"This is the "last" part of the support for the new nbcon consoles.
Where "nbcon" stays for "No Big console lock CONsoles" aka not under
the console_lock.
New callbacks are added to struct console:
- write_thread() for flushing nbcon consoles in task context.
- write_atomic() for flushing nbcon consoles in atomic context,
including NMI.
- con->device_lock() and device_unlock() for taking the driver
specific lock, for example, port->lock.
New printk-specific kthreads are created:
- per-console kthreads which get responsible for flushing normal
priority messages on nbcon consoles.
- thread which gets responsible for flushing normal priority messages
on all consoles when CONFIG_RT enabled.
The new callbacks are called under a special per-console lock which
has already been added back in v6.7. It allows to distinguish three
severities: normal, emergency, and panic. A context with a higher
priority could take over the ownership when it is safe even in the
middle of handling a record. The panic context could do it even when
it is not safe. But it is allowed only for the final desperate flush
before entering the infinite loop.
The new lock helps to flush the messages directly in emergency and
panic contexts. But it is not enough in all situations:
- console_lock() is still need for synchronization against boot
consoles.
- con->device_lock() is need for synchronization against other
operations on the same HW, e.g. serial port speed setting,
non-printk related read/write.
The dependency on con->device_lock() is mutual. Any code taking the
driver specific lock has to acquire the related nbcon console context
as well. For example, see the new uart_port_lock() API. It provides
the necessary synchronization against emergency and panic contexts
where the messages are flushed only under the new per-console lock.
Maybe surprisingly, a quite tricky part is the decision how to flush
the consoles in various situations. It has to take into account:
- message priority: normal, emergency, panic
- scheduling context: task, atomic, deferred_legacy
- registered consoles: boot, legacy, nbcon
- threads are running: early boot, suspend, shutdown, panic
- caller: printk(), pr_flush(), printk_flush_in_panic(),
console_unlock(), console_start(), ...
The primary decision is made in printk_get_console_flush_type(). It
creates a hint what the caller should do:
- flush nbcon consoles directly or via the kthread
- call the legacy loop (console_unlock()) directly or via irq_work
The existing behavior is preserved for the legacy consoles. The only
exception is that they are not longer flushed directly from printk()
in panic() before CPUs are stopped. But this blocking happens only
when at least one nbcon console is registered. The motivation is to
increase a chance to produce the crash dump. They legacy consoles
might create a deadlock in compare with nbcon consoles. The nbcon
console should allow to see the messages even when the crash dump
fails.
There are three possible ways how nbcon consoles are flushed:
- The per-nbcon-console kthread is responsible for flushing messages
added with the normal priority. This is the default mode.
- The legacy loop, aka console_unlock(), is used when there is still
a boot console registered. There is no easy way how to match an
early console driver with a nbcon console driver. And the
console_lock() provides the only reliable serialization at the
moment.
The legacy loop uses either con->write_atomic() or
con->write_thread() callbacks depending on whether it is allowed to
schedule. The atomic variant has to be used from printk().
- In other situations, the messages are flushed directly using
write_atomic() which can be called in any context, including NMI.
It is primary needed during early boot or shutdown, in emergency
situations, and panic.
The emergency priority is used by a code called within
nbcon_cpu_emergency_enter()/exit(). At the moment, it is used in four
situations: WARN(), Oops, lockdep, and RCU stall reports.
Finally, there is no nbcon console at the moment. It means that the
changes should _not_ modify the existing behavior. The only exception
is CONFIG_RT which would force offloading the legacy loop, for normal
priority context, into the dedicated kthread"

A set of updates for debugobjects:
- Use the threshold to check for the pool refill condition and not the
run time recorded all time low fill value, which is lower than the
threshold and therefore causes refills to be delayed.
- KCSAN annotation updates and simplification of the fill_pool() code.

Updates for timers and timekeeping:
- Core:
- Overhaul of posix-timers in preparation of removing the
workaround for periodic timers which have signal delivery
ignored.
- Remove the historical extra jiffie in msleep()
msleep() adds an extra jiffie to the timeout value to ensure
minimal sleep time. The timer wheel ensures minimal sleep
time since the large rewrite to a non-cascading wheel, but the
extra jiffie in msleep() remained unnoticed. Remove it.
- Make the timer slack handling correct for realtime tasks.
The procfs interface is inconsistent and does neither reflect
reality nor conforms to the man page. Show the correct 0 slack
for real time tasks and enforce it at the core level instead of
having inconsistent individual checks in various timer setup
functions.
- The usual set of updates and enhancements all over the place.
- Drivers:
- Allow the ACPI PM timer to be turned off during suspend
- No new drivers
- The usual updates and enhancements in various drivers

Updates for the interrupt subsystem:
- Core:
- Remove a global lock in the affinity setting code
The lock protects a cpumask for intermediate results and the lock
causes a bottleneck on simultaneous start of multiple virtual
machines. Replace the lock and the static cpumask with a per CPU
cpumask which is nicely serialized by raw spinlock held when
executing this code.
- Provide support for giving a suffix to interrupt domain names.
That's required to support devices with subfunctions so that the
domain names are distinct even if they originate from the same
device node.
- The usual set of cleanups and enhancements all over the place
- Drivers:
- Support for longarch AVEC interrupt chip
- Refurbishment of the Armada driver so it can be extended for new
variants.
