alloc_tag: fix allocation tag reporting when CONFIG_MODULES=n
codetag_module_init() is used to initialize sections containing allocation
tags. This function is used to initialize module sections as well as core
kernel sections, in which case the module parameter is set to NULL. This
function has to be called even when CONFIG_MODULES=n to initialize core
kernel allocation tag sections. When CONFIG_MODULES=n, this function is a
NOP, which is wrong. This leads to /proc/allocinfo reported as empty.
Fix this by making it independent of CONFIG_MODULES.

mm: vmalloc: optimize vmap_lazy_nr arithmetic when purging each vmap_area
When running the vmalloc stress on a 448-core system, observe the average

The worst case is over 16-33 seconds, so soft lockup is triggered [2].
[Root Cause]
1) Each purge_list has the long list. The following shows the number of
vmap_area is purged.
crash> p vmap_nodes
vmap_nodes = $27 = (struct vmap_node *) 0xff2de5a900100000
crash> vmap_node 0xff2de5a900100000 128 | grep nr_purged
nr_purged = 663070
...
nr_purged = 821670
nr_purged = 692214
nr_purged = 726808
...
2) atomic_long_sub() employs the 'lock' prefix to ensure the atomic
operation when purging each vmap_area. However, the iteration is over
600000 vmap_area (See 'nr_purged' above).
Here is objdump output:
$ objdump -D vmlinux
ffffffff813e8c80 <purge_vmap_node>:
...
ffffffff813e8d70: f0 48 29 2d 68 0c bb lock sub %rbp,0x2bb0c68(%rip)
...
Quote from "Instruction tables" pdf file [3]:
Instructions with a LOCK prefix have a long latency that depends on
cache organization and possibly RAM speed. If there are multiple
processors or cores or direct memory access (DMA) devices, then all
locked instructions will lock a cache line for exclusive access,
which may involve RAM access. A LOCK prefix typically costs more
than a hundred clock cycles, even on single-processor systems.
That's why the latency of purge_vmap_node() dramatically increases
on a many-core system: One core is busy on purging each vmap_area of
the *long* purge_list and executing atomic_long_sub() for each
vmap_area, while other cores free vmalloc allocations and execute
atomic_long_add_return() in free_vmap_area_noflush().
[Solution]
Employ a local variable to record the total purged pages, and execute
atomic_long_sub() after the traversal of the purge_list is done. The
experiment result shows the latency improvement is 99%.
[Experiment Result]
1) System Configuration: Three servers (with HT-enabled) are tested.
* 72-core server: 3rd Gen Intel Xeon Scalable Processor*1
* 192-core server: 5th Gen Intel Xeon Scalable Processor*2
* 448-core server: AMD Zen 4 Processor*2
2) Kernel Config
* CONFIG_KASAN is disabled
3) The data in column "w/o patch" and "w/ patch"
* Unit: micro seconds (us)
* Each data is the average of 3-time measurements

codetag: debug: mark codetags for poisoned page as empty
When PG_hwpoison pages are freed they are treated differently in
free_pages_prepare() and instead of being released they are isolated.
Page allocation tag counters are decremented at this point since the page
is considered not in use. Later on when such pages are released by
unpoison_memory(), the allocation tag counters will be decremented again
and the following warning gets reported:

mm/memcontrol: respect zswap.writeback setting from parent cg too
Currently, the behavior of zswap.writeback wrt. the cgroup hierarchy
seems a bit odd. Unlike zswap.max, it doesn't honor the value from parent
cgroups. This surfaced when people tried to globally disable zswap
writeback, i.e. reserve physical swap space only for hibernation [1] -
disabling zswap.writeback only for the root cgroup results in subcgroups
with zswap.writeback=1 still performing writeback.
The inconsistency became more noticeable after I introduced the
MemoryZSwapWriteback= systemd unit setting [2] for controlling the knob.
The patch assumed that the kernel would enforce the value of parent
cgroups. It could probably be workarounded from systemd's side, by going
up the slice unit tree and inheriting the value. Yet I think it's more
sensible to make it behave consistently with zswap.max and friends.

kexec_file: fix elfcorehdr digest exclusion when CONFIG_CRASH_HOTPLUG=y
Fix the condition to exclude the elfcorehdr segment from the SHA digest
calculation.
The j iterator is an index into the output sha_regions[] array, not into
the input image->segment[] array. Once it reaches
image->elfcorehdr_index, all subsequent segments are excluded. Besides,
if the purgatory segment precedes the elfcorehdr segment, the elfcorehdr
may be wrongly included in the calculation.

mm/slub: add check for s->flags in the alloc_tagging_slab_free_hook
When enable CONFIG_MEMCG & CONFIG_KFENCE & CONFIG_KMEMLEAK, the following
warning always occurs,This is because the following call stack occurred:
mem_pool_alloc
kmem_cache_alloc_noprof
slab_alloc_node
kfence_alloc
Once the kfence allocation is successful,slab->obj_exts will not be empty,
because it has already been assigned a value in kfence_init_pool.
Since in the prepare_slab_obj_exts_hook function,we perform a check for
s->flags & (SLAB_NO_OBJ_EXT | SLAB_NOLEAKTRACE),the alloc_tag_add function
will not be called as a result.Therefore,ref->ct remains NULL.
However,when we call mem_pool_free,since obj_ext is not empty, it
eventually leads to the alloc_tag_sub scenario being invoked. This is
where the warning occurs.
So we should add corresponding checks in the alloc_tagging_slab_free_hook.
For __GFP_NO_OBJ_EXT case,I didn't see the specific case where it's using
kfence,so I won't add the corresponding check in
alloc_tagging_slab_free_hook for now.

nilfs2: fix missing cleanup on rollforward recovery error
In an error injection test of a routine for mount-time recovery, KASAN
found a use-after-free bug.
It turned out that if data recovery was performed using partial logs
created by dsync writes, but an error occurred before starting the log
writer to create a recovered checkpoint, the inodes whose data had been
recovered were left in the ns_dirty_files list of the nilfs object and
were not freed.
Fix this issue by cleaning up inodes that have read the recovery data if
the recovery routine fails midway before the log writer starts.

nilfs2: protect references to superblock parameters exposed in sysfs
The superblock buffers of nilfs2 can not only be overwritten at runtime
for modifications/repairs, but they are also regularly swapped, replaced
during resizing, and even abandoned when degrading to one side due to
backing device issues. So, accessing them requires mutual exclusion using
the reader/writer semaphore "nilfs->ns_sem".
Some sysfs attribute show methods read this superblock buffer without the
necessary mutual exclusion, which can cause problems with pointer
dereferencing and memory access, so fix it.

userfaultfd: don't BUG_ON() if khugepaged yanks our page table
Since khugepaged was changed to allow retracting page tables in file
mappings without holding the mmap lock, these BUG_ON()s are wrong - get
rid of them.
We could also remove the preceding "if (unlikely(...))" block, but then we
could reach pte_offset_map_lock() with transhuge pages not just for file
mappings but also for anonymous mappings - which would probably be fine
but I think is not necessarily expected.

userfaultfd: fix checks for huge PMDs
Patch series "userfaultfd: fix races around pmd_trans_huge() check", v2.
The pmd_trans_huge() code in mfill_atomic() is wrong in three different
ways depending on kernel version:
1. The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit
the right two race windows) - I've tested this in a kernel build with
some extra mdelay() calls. See the commit message for a description
of the race scenario.
On older kernels (before 6.5), I think the same bug can even
theoretically lead to accessing transhuge page contents as a page table
if you hit the right 5 narrow race windows (I haven't tested this case).
2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for
detecting PMDs that don't point to page tables.
On older kernels (before 6.5), you'd just have to win a single fairly
wide race to hit this.
I've tested this on 6.1 stable by racing migration (with a mdelay()
patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86
VM, that causes a kernel oops in ptlock_ptr().
3. On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed
to yank page tables out from under us (though I haven't tested that),
so I think the BUG_ON() checks in mfill_atomic() are just wrong.
I decided to write two separate fixes for these (one fix for bugs 1+2, one
fix for bug 3), so that the first fix can be backported to kernels
affected by bugs 1+2.
This patch (of 2):
This fixes two issues.
I discovered that the following race can occur:
mfill_atomic other thread
============ ============
<zap PMD>
pmdp_get_lockless() [reads none pmd]
<bail if trans_huge>
<if none:>
<pagefault creates transhuge zeropage>
__pte_alloc [no-op]
<zap PMD>
<bail if pmd_trans_huge(*dst_pmd)>
BUG_ON(pmd_none(*dst_pmd))
I have experimentally verified this in a kernel with extra mdelay() calls;
the BUG_ON(pmd_none(*dst_pmd)) triggers.
On kernels newer than commit

selftests: mm: fix build errors on armhf
The __NR_mmap isn't found on armhf. The mmap() is commonly available
system call and its wrapper is present on all architectures. So it should
be used directly. It solves problem for armhf and doesn't create problem
for other architectures.
Remove sys_mmap() functions as they aren't doing anything else other than
calling mmap(). There is no need to set errno = 0 manually as glibc
always resets it.
For reference errors are as following:
CC seal_elf
seal_elf.c: In function 'sys_mmap':
seal_elf.c:39:33: error: '__NR_mmap' undeclared (first use in this function)
39 | sret = (void *) syscall(__NR_mmap, addr, len, prot,

A set of X86 fixes:
- x2apic_disable() clears x2apic_state and x2apic_mode unconditionally,
even when the state is X2APIC_ON_LOCKED, which prevents the kernel to
disable it thereby creating inconsistent state.
Reorder the logic so it actually works correctly
- The XSTATE logic for handling LBR is incorrect as it assumes that
XSAVES supports LBR when the CPU supports LBR. In fact both conditions
need to be true. Otherwise the enablement of LBR in the IA32_XSS MSR
fails and subsequently the machine crashes on the next XRSTORS
operation because IA32_XSS is not initialized.
Cache the XSTATE support bit during init and make the related functions
use this cached information and the LBR CPU feature bit to cure this.
- Cure a long standing bug in KASLR
KASLR uses the full address space between PAGE_OFFSET and vaddr_end to
randomize the starting points of the direct map, vmalloc and vmemmap
regions. It thereby limits the size of the direct map by using the
installed memory size plus an extra configurable margin for hot-plug
memory. This limitation is done to gain more randomization space
because otherwise only the holes between the direct map, vmalloc,
vmemmap and vaddr_end would be usable for randomizing.
The limited direct map size is not exposed to the rest of the kernel, so
the memory hot-plug and resource management related code paths still
operate under the assumption that the available address space can be
determined with MAX_PHYSMEM_BITS.
request_free_mem_region() allocates from (1 << MAX_PHYSMEM_BITS) - 1
downwards. That means the first allocation happens past the end of the
direct map and if unlucky this address is in the vmalloc space, which
causes high_memory to become greater than VMALLOC_START and consequently
causes iounmap() to fail for valid ioremap addresses.
Cure this by exposing the end of the direct map via PHYSMEM_END and use
that for the memory hot-plug and resource management related places
instead of relying on MAX_PHYSMEM_BITS. In the KASLR case PHYSMEM_END
maps to a variable which is initialized by the KASLR initialization and
otherwise it is based on MAX_PHYSMEM_BITS as before.
- Prevent a data leak in mmio_read(). The TDVMCALL exposes the value of
an initialized variabled on the stack to the VMM. The variable is only
required as output value, so it does not have to exposed to the VMM in
the first place.
- Prevent an array overrun in the resource control code on systems with
Sub-NUMA Clustering enabled because the code failed to adjust the index
by the number of SNC nodes per L3 cache.

The recent conversion of the PLIC driver to a platform driver broke
Allwinnder D1 systems due to the deferred probing of platform drivers.
Due to that the only timer available on D1 systems cannot get an
interrupt, which causes the system to hang at boot. Other RISCV
platforms are not affected because they provide the architected SBI
timer which uses the built in core interrupt controller.
Cure this by probing PLIC early on D1 systems
- Cure a regression in ARM/GIC-V3 on 32-bit ARM systems caused by the
recent addition of a initialization function, which accesses system
registers before they are enabled. On 64-bit ARM they are enabled
prior to that by sheer luck.
Ensure they are enabled.
- Cure a use before check problem in the MSI library. The existing NULL
pointer check is too late.
- Cure a lock order inversion in the ARM/GIC-V4 driver

bcachefs: Mark more errors as autofix
errors that are known to always be safe to fix should be autofix: this should be most errors even at this point, but that will need some thorough review. note that errors are still logged in the superblock, so we'll still know that they happened.

bcachefs: Revert lockless buffered IO path
We had a report of data corruption on nixos when building installer
images.
https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334
It seems that writes are being dropped, but only when issued by QEMU,
and possibly only in snapshot mode. It's undetermined if it's write
calls are being dropped or dirty folios.
Further testing, via minimizing the original patch to just the change
that skips the inode lock on non appends/truncates, reveals that it
really is just not taking the inode lock that causes the corruption: it
has nothing to do with the other logic changes for preserving write
atomicity in corner cases.
It's also kernel config dependent: it doesn't reproduce with the minimal
kernel config that ktest uses, but it does reproduce with nixos's distro
config. Bisection the kernel config initially pointer the finger at page
migration or compaction, but it appears that was erroneous; we haven't
yet determined what kernel config option actually triggers it.
Sadly it appears this will have to be reverted since we're getting too
close to release and my plate is full, but we'd _really_ like to fully
debug it.
My suspicion is that this patch is exposing a preexisting bug - the
inode lock actually covers very little in IO paths, and we have a
different lock (the pagecache add lock) that guards against races with
truncate here.

than "inode btree" blocks.
* Don't report the number of trimmed bytes via FITRIM because the underlying
storage isn't required to do anything and failed discard IOs aren't
reported to the caller anyway.
* Fix incorrect setting of rm_owner field in an rmap query.
* Report missing disk offset range in an fsmap query.
* Obtain m_growlock when extending realtime section of the filesystem.
* Reset rootdir extent size hint after extending realtime section of the

ARM: SoC fixes for 6.11, part 2
There is a fairly large number of bug fixes for Qualcomm platforms, most of them addressing issues with the devicetree files for the newly added Snapdragon X1 based laptops to make them more reliable. The Qualcomm driver changes address a few build-time issues as well as runtime problems in the tzmem and scm firmware, the USB Type-C driver, and the cmd-db and pmic_glink soc drivers. The NXP i.MX usually gets a bunch of devicetree fixes that is proportional to the number of supported machines. This includes both warning fixes and correctness for the 64-bit i.MX9, i.MX8 and layerscape platforms, as well as a single fix for a 32-bit i.MX6 based board. The other changes are the usual minor changes, including an update to the MAINTAINERS file, an omap3 dts file and a SoC driver for mpfs (risc-v). -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmbSNOgACgkQYKtH/8kJ UieuWg//eW9qg16Fw7ZeEDSrq7s7Mrr03zcF+Xqb1wpZZqDbUqgSWqaDDapd//bW st7eR2rxm5yySBRbYFNa/jjB7YQA1GSlYtFn3cBEe/lFiuhOeP5yWwKTT05yeWDr RzkPSDIt30YDsYV6+k5HpyzRNeuOd7QaVOz9XKqnEgzuRKC89OcSkHmXQUhvvbrg f+5/uSFTZBAYjUpuH3ZRX9elRYsHSYlsmLI71HWRIBZrvNWwv3O4N0nySbCdhE0V 8hb3fCo/39rdjWjKuGHigsvxMLLmooFNvu/r/oZtqUjFDIjOkVzxI14K/yl2al7v nmEHnwFqTsTIGP21CmRV4fzrS/80gld3ieLavC9kZaWqfV9yMjF1+jg40qsrUXcR /Gfzq7XCrqx9CpFA62uytjkQZI5tk9Ip9FQHK80+OsDq8/zCJs77NIwR26VNT3O/ HIf9yTdC4bzZW1hUpTsIy+/piSWja5kkSKHn5Zcqby05hPUjWe/utiBKW3lTE9OI EJ4swrHOenGea0AEeR2Rp5WOVfq26q12m4GYCi5YM+FGr64KHf5URQ1GoRTxorAx YLa8xGm88CfIU3rnW90b2/5lYgqAyL3xEq9p1qt9HmZx/0SuoGbV1EekgfPd52yV hrkn2gnNGS+A2ldqSRGZVJQSxKIpISORDj4y3sAI+JEQmm0UEM0= =tK5m -----END PGP SIGNATURE----- Merge tag 'arm-fixes-6.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Arnd Bergmann: "There is a fairly large number of bug fixes for Qualcomm platforms, most of them addressing issues with the devicetree files for the newly added Snapdragon X1 based laptops to make them more reliable.

Power management fixes for 6.11-rc6
- Remove checks for highest performance match on preferred cores when
updating preferred core ranking in amd-pstate (Mario Limonciello).
- Make amd-pstate call topology_logical_package_id() instead of
logical_die_id() to get a socked ID for a CPU (Gautham Shenoy).
- Fix uninitialized variable in amd_pstate_cpu_boost_update() (Dan
Carpenter).
