x86/stackprotector: Work around strict Clang TLS symbol requirements
GCC and Clang both implement stack protector support based on Thread Local
Storage (TLS) variables, and this is used in the kernel to implement per-task
stack cookies, by copying a task's stack cookie into a per-CPU variable every
time it is scheduled in.
Both now also implement -mstack-protector-guard-symbol=, which permits the TLS
variable to be specified directly. This is useful because it will allow to
move away from using a fixed offset of 40 bytes into the per-CPU area on
x86_64, which requires a lot of special handling in the per-CPU code and the
runtime relocation code.
However, while GCC is rather lax in its implementation of this command line
option, Clang actually requires that the provided symbol name refers to a TLS
variable (i.e., one declared with __thread), although it also permits the
variable to be undeclared entirely, in which case it will use an implicit
declaration of the right type.
The upshot of this is that Clang will emit the correct references to the stack
cookie variable in most cases, e.g.,
10d: 64 a1 00 00 00 00 mov %fs:0x0,%eax
10f: R_386_32 __stack_chk_guard
However, if a non-TLS definition of the symbol in question is visible in the
same compilation unit (which amounts to the whole of vmlinux if LTO is
enabled), it will drop the per-CPU prefix and emit a load from a bogus
address.
Work around this by using a symbol name that never occurs in C code, and emit
it as an alias in the linker script.

x86/CPU/AMD: Clear virtualized VMLOAD/VMSAVE on Zen4 client
A number of Zen4 client SoCs advertise the ability to use virtualized VMLOAD/VMSAVE, but using these instructions is reported to be a cause of a random host reboot. These instructions aren't intended to be advertised on Zen4 client so clear the capability.

mm: multi-gen LRU: use {ptep,pmdp}_clear_young_notify()
When the MM_WALK capability is enabled, memory that is mostly accessed by
a VM appears younger than it really is, therefore this memory will be less
likely to be evicted. Therefore, the presence of a running VM can
significantly increase swap-outs for non-VM memory, regressing the
performance for the rest of the system.
Fix this regression by always calling {ptep,pmdp}_clear_young_notify()
whenever we clear the young bits on PMDs/PTEs.

mm: multi-gen LRU: remove MM_LEAF_OLD and MM_NONLEAF_TOTAL stats
Patch series "mm: multi-gen LRU: Have secondary MMUs participate in
MM_WALK".
Today, the MM_WALK capability causes MGLRU to clear the young bit from
PMDs and PTEs during the page table walk before eviction, but MGLRU does
not call the clear_young() MMU notifier in this case. By not calling this
notifier, the MM walk takes less time/CPU, but it causes pages that are
accessed mostly through KVM / secondary MMUs to appear younger than they
should be.
We do call the clear_young() notifier today, but only when attempting to
evict the page, so we end up clearing young/accessed information less
frequently for secondary MMUs than for mm PTEs, and therefore they appear
younger and are less likely to be evicted. Therefore, memory that is
*not* being accessed mostly by KVM will be evicted *more* frequently,
worsening performance.
ChromeOS observed a tab-open latency regression when enabling MGLRU with a
setup that involved running a VM:
Tab-open latency histogram (ms)
Version p50 mean p95 p99 max
base 1315 1198 2347 3454 10319
mglru 2559 1311 7399 12060 43758
fix 1119 926 2470 4211 6947
This series replaces the final non-selftest patchs from this series[1],
which introduced a similar change (and a new MMU notifier) with KVM
optimizations. I'll send a separate series (to Sean and Paolo) for the
KVM optimizations.
This series also makes proactive reclaim with MGLRU possible for KVM
memory. I have verified that this functions correctly with the selftest
from [1], but given that that test is a KVM selftest, I'll send it with
the rest of the KVM optimizations later. Andrew, let me know if you'd
like to take the test now anyway.
[1]: https://lore.kernel.org/linux-mm/20240926013506.860253-18-jthoughton@google.com/
This patch (of 2):
The removed stats, MM_LEAF_OLD and MM_NONLEAF_TOTAL, are not very helpful
and become more complicated to properly compute when adding
test/clear_young() notifiers in MGLRU's mm walk.

A single fix for posix CPU timers
When a thread is cloned, the posix CPU timers are not inherited. If the parent has a CPU timer armed the corresponding tick dependency in the tasks tick_dep_mask is set and copied to the new thread, which means the new thread and all decendants will prevent the system to go into full NOHZ operation. Clear the tick dependency mask in copy_process() to fix this. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmcnT/oTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoZw5D/0bqjjMYiE0ws8nuuXN1gL2T1wt6P2C 2zzEKnk6nsxnGbMfFs7XifDkqSOHNVro7F6kCkz6cH4U/VSK6R2nNONbufz4mNWk 6uDvdlZps30ekmxN+C3fB6S/4MNVOhXFFXjsQhT/PxX/CfibVP5fATLtcRLq9Lfx mV3nnxKTHPjDGz2/2QRyYpA3G1fzOj/l2QeJsVAIC8GxCo7drLVe0yn5Yt+13zhU JMjgt9ox4PKFsjaXrqvt1yKNTtb+evjYSIVXxIg60oxUkfva6XFLXJv3rjbARUNj aqBHfkZ1/d2Hwc0WexDZfvhNWeCqnfUA+db7ALSYICbNd37EVxWVZA2TwfkkWKSt RDq3xX6NJSd71h0lxDvzv7Ph3NUq23rq3LycAkjqfhiFjPQmE6axtnioXcR5mtVp q9tilB/3I4zj4BIYPfd9KowkdclRSK+B3Oo0DTyuVhKLggF0UD3poDxT4HxnBCFB uKDV8GDsoD8Ksjsl0/X/D4oorqLYAT0tG9gxMw1Kii16gijhhu5qeqTWY+qs9ieg 2J+Ku83QLQgljvy2s7y0AnMZMxaeKN5YMs6zNV+yGAoTFyft3CnBMKalPHfOCI0A fdKHi2aKm+lLrp/UIG2Yw9N1xfcrGWA2moH+9dw6zTyAei+TInP+WYndI7VR5EDf 3KvW3OoRf0sywA== =83r/ -----END PGP SIGNATURE----- Merge tag 'timers-urgent-2024-11-03' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer fix from Thomas Gleixner: "A single fix for posix CPU timers.

A few scheduler fixes:
- Plug a race between pick_next_task_fair() and try_to_wake_up() where
both try to write to the same task, even though both paths hold a
runqueue lock, but obviously from different runqueues.
The problem is that the store to task::on_rq in __block_task() is
visible to try_to_wake_up() which assumes that the task is not queued.
Both sides then operate on the same task.
Cure it by rearranging __block_task() so the the store to task::on_rq is
the last operation on the task.
- Prevent a potential NULL pointer dereference in task_numa_work()
task_numa_work() iterates the VMAs of a process. A concurrent unmap of
the address space can result in a NULL pointer return from vma_next()
which is unchecked.
Add the missing NULL pointer check to prevent this.
- Operate on the correct scheduler policy in task_should_scx()
task_should_scx() returns true when a task should be handled by sched
EXT. It checks the tasks scheduling policy.
This fails when the check is done before a policy has been set.
Cure it by handing the policy into task_should_scx() so it operates
on the requested value.
- Add the missing handling of sched EXT in the delayed dequeue
mechanism. This was simply forgotten.

Two fixes for the interrupt subsystem:
- Fix an off-by-one error in the failure path of msi_domain_alloc(),
which causes the cleanup loop to terminate early and leaking the first
allocated interrupt.
- Handle a corner case in GIC-V4 versus a lazily mapped Virtual
Processing Element (VPE). If the VPE has not been mapped because the
guest has not yet emitted a mapping command, then the set_affinity()
callback returns an error code, which causes the vCPU management to fail.
Return success in this case without touching the hardware. This will be
done later when the guest issues the mapping command.

modpost: fix input MODULE_DEVICE_TABLE() built for 64-bit on 32-bit host
When building a 64-bit kernel on a 32-bit build host, incorrect
input MODULE_ALIAS() entries may be generated.
For example, when compiling a 64-bit kernel with CONFIG_INPUT_MOUSEDEV=m
on a 64-bit build machine, you will get the correct output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*r*0,*1,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*r*a*0,*1,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*r*a*0,*1,*18,*1C,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*r*a*0,*1,*m*l*s*f*w*");
However, building the same kernel on a 32-bit machine results in
incorrect output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*130,*r*0,*1,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*16A,*r*a*0,*1,*20,*21,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*165,*r*a*0,*1,*18,*1C,*20,*21,*38,*3C,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*130,*r*a*0,*1,*20,*21,*m*l*s*f*w*");
A similar issue occurs with CONFIG_INPUT_JOYDEV=m. On a 64-bit build
machine, the output is:
$ grep MODULE_ALIAS drivers/input/joydev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*0,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*2,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*8,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*6,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*120,*r*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*130,*r*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*2C0,*r*a*m*l*s*f*w*");
However, on a 32-bit machine, the output is incorrect:
$ grep MODULE_ALIAS drivers/input/joydev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*0,*20,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*2,*22,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*8,*28,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*6,*26,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*11F,*13F,*r*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*11F,*13F,*r*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*2C0,*2E0,*r*a*m*l*s*f*w*");
When building a 64-bit kernel, BITS_PER_LONG is defined as 64. However,
on a 32-bit build machine, the constant 1L is a signed 32-bit value.
Left-shifting it beyond 32 bits causes wraparound, and shifting by 31
or 63 bits makes it a negative value.

modpost: fix acpi MODULE_DEVICE_TABLE built with mismatched endianness
When CONFIG_SATA_AHCI_PLATFORM=m, modpost outputs incorect acpi
MODULE_ALIAS() if the endianness of the target and the build machine
do not match.
When the endianness of the target kernel and the build machine match,
the output is correct:
$ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:010601:*");
However, when building a little-endian kernel on a big-endian machine
(or vice versa), the output is incorrect:
$ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:0601??:*");
The 'cls' and 'cls_msk' fields are 32-bit.
DEF_FIELD() must be used instead of DEF_FIELD_ADDR() to correctly handle
endianness of these 32-bit fields.
The check 'if (cls)' was unnecessary; it never became NULL, as it was
the pointer to 'symval' plus the offset to the 'cls' field.

Rust fixes for v6.12 (3nd)
Toolchain and infrastructure:
- Avoid build errors with old 'rustc's without LLVM patch version
(important since it impacts people that do not even enable Rust).
- Update LLVM version for 'HAVE_CFI_ICALL_NORMALIZE_INTEGERS' in
'depends on' condition (the fix was eventually backported rather than
land in LLVM 19).

In summary, cxl_acpi and cxl_mem race and previously worked because of a bus_rescan_devices() while testing without modules built in. Unfortunately with modules built in the rescan would fail due to the cxl_port driver being registered late via the build order. Furthermore it was found bus_rescan_devices() did not guarantee a probe barrier which CXL was expecting. Additional fixes to cxl-test and decoder allocation came along as they were found in this debugging effort. The other fixes are pretty minor but one affects trace point data seen by user space.

RISC-V Fixes for 6.11-rc6
* A fix that avoids accessing the early boot ACPI tables via unsafe memory attributes, which can result in incorrect ACPI table data appearing. This can cause all sorts of bad behavior. * A fix to avoid compiler-insert library calls in the VDSO. * GCC+Rust builds have been disabled, to avoid issues related to ISA string mismatched between the GCC and LLVM Rust implementations. * The NX flag is now set in the EFI PE/COFF headers, which is necessary for some distro GRUB versions to boot images. * A fix to avoid leaking DT node reference counts on ACPI systems during cache info parsing. * CPU numbers are now printed as unsigned values during hotplug. * A pair of build fixes for usused macros, which can trigger warnings on some configurations. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmck63wTHHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYiZiID/4kBXBpJ3vAt3xmu7tlt/Y29EICJeMs aVZTHtH89K3VhN9M3F6a+loJquKyg7mhDoz5diEiJ5yzRPlrXzqhPePlilQD+Akz P33B/2jHNv7xs/wZ6e0GOSF0J5baIWBnL2rJ43daGXfj+Qw4RvQEN2yt2+GxqJq7 vXeLQRC4RLfRjKPMMC3sT4ihNsDzFuOUYQG9kAHo6sJy8+N6NqXx3IOEh8z6qZmF 8RpWCrxxIwZJKWm0d47NrHPn/ztXdHcrKbANND3/5uye7WNEt++o5Kc6nCuxp5mo R1M+OoonTBMLXzeqZ9SSDpTywHYlrXmzl3IAyrbO2XYm+4sERN7AV1FwS9AzgiF4 b1pe5LnwWRzZstcnmgSQylU31gSTeswGi25jd+zMJIdZLreEUim3eIE2Hp3sh1ys YGtkDqW3VLGnJKGlvmfM2m4iFhYNTMj2GEuIymFyECa4Kv3qiMPsbPmZLHKvTYaq 3II4oCx4wdYHiBbV3FvCdp6QkJjr6VdqC2dIYuNE/06mNhN+1ccZ60z/llL39wda EWFEK5R5RES2DHmGEz0mhMRcqBilEWhdi4+S1Wi/E06dtGBJpcsTkLXfzCWbYGxw 4l2K91jDMV/EiuG57dX2CfuavgThhGyOeLxgId+17n28CYPNExy8BKprZjDI0p2L 4mzwbcP/KcO3XA== =sqa0 -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-6.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V fixes from Palmer Dabbelt: - Avoid accessing the early boot ACPI tables via unsafe memory attributes, which can result in incorrect ACPI table data appearing.

- Fix handling of POR_EL0 during signal delivery so that pushing the
signal context doesn't fail based on the pkey configuration of the
interrupted context and align our user-visible behaviour with that of
x86.
- Fix a bogus pointer being passed to the CPU hotplug code from the
Arm SDEI driver.
- Re-enable software tag-based KASAN with GCC by using an alternative
implementation of '__no_sanitize_address'.

"The important one is a change to the way in which we handle protection
keys around signal delivery so that we're more closely aligned with
the x86 behaviour, however there is also a revert of the previous fix
to disable software tag-based KASAN with GCC, since a workaround
materialised shortly afterwards.
I'd love to say we're done with 6.12, but we're aware of some
longstanding fpsimd register corruption issues that we're almost at
the bottom of resolving.

bcachefs fixes for 6.12-rc6
Various syzbot fixes, and the more notable ones:
- Fix for pointers in an extent overflowing the max (16) on a filesystem
with many devices: we were creating too many cached copies when moving
data around. Now, we only create at most one cached copy if there's a
promote target set.
Caching will be a bit broken for reflinked data until 6.13: I have
larger series queued up which significantly improves the plumbing for
data options down into the extent (bch_extent_rebalance) to fix this.
- Fix for deadlock on -ENOSPC on tiny filesystems
Allocation from the partial open_bucket list wasn't correctly
accounting partial open_buckets as free: this fixes the main cause of
tests timing out in the automated tests.

vmscan,migrate: fix page count imbalance on node stats when demoting pages
When numa balancing is enabled with demotion, vmscan will call
migrate_pages when shrinking LRUs. migrate_pages will decrement the
the node's isolated page count, leading to an imbalanced count when
invoked from (MG)LRU code.
The result is dmesg output like such:
$ cat /proc/sys/vm/stat_refresh
[77383.088417] vmstat_refresh: nr_isolated_anon -103212
[77383.088417] vmstat_refresh: nr_isolated_file -899642
This negative value may impact compaction and reclaim throttling.
The following path produces the decrement:
shrink_folio_list
demote_folio_list
migrate_pages
migrate_pages_batch
migrate_folio_move
migrate_folio_done
mod_node_page_state(-ve) <- decrement
This path happens for SUCCESSFUL migrations, not failures. Typically
callers to migrate_pages are required to handle putback/accounting for
failures, but this is already handled in the shrink code.
When accounting for migrations, instead do not decrement the count when
the migration reason is MR_DEMOTION. As of v6.11, this demotion logic
is the only source of MR_DEMOTION.
