mm/debug_vm_pgtable: fix BUG_ON with pud advanced test
Architectures like powerpc add debug checks to ensure we find only devmap
PUD pte entries. These debug checks are only done with CONFIG_DEBUG_VM.
This patch marks the ptes used for PUD advanced test devmap pte entries so
that we don't hit on debug checks on architecture like ppc64 as below.

mm: cachestat: fix folio read-after-free in cache walk
In cachestat, we access the folio from the page cache's xarray to compute
its page offset, and check for its dirty and writeback flags. However, we
do not hold a reference to the folio before performing these actions,
which means the folio can concurrently be released and reused as another
folio/page/slab.
Get around this altogether by just using xarray's existing machinery for
the folio page offsets and dirty/writeback states.
This changes behavior for tmpfs files to now always report zeroes in their
dirty and writeback counters. This is okay as tmpfs doesn't follow
conventional writeback cache behavior: its pages get "cleaned" during
swapout, after which they're no longer resident etc.

mm/vmscan: fix a bug calling wakeup_kswapd() with a wrong zone index
With numa balancing on, when a numa system is running where a numa node
doesn't have its local memory so it has no managed zones, the following
oops has been observed. It's because wakeup_kswapd() is called with a
wrong zone index, -1. Fixed it by checking the index before calling
wakeup_kswapd().

kasan: revert eviction of stack traces in generic mode

stackdepot: use variable size records for non-evictable entries
With the introduction of stack depot evictions, each stack record is now
fixed size, so that future reuse after an eviction can safely store
differently sized stack traces. In all cases that do not make use of
evictions, this wastes lots of space.
Fix it by re-introducing variable size stack records (up to the max
allowed size) for entries that will never be evicted. We know if an entry
will never be evicted if the flag STACK_DEPOT_FLAG_GET is not provided,
since a later stack_depot_put() attempt is undefined behavior.
With my current kernel config that enables KASAN and also SLUB owner
tracking, I observe (after a kernel boot) a whopping reduction of 296
stack depot pools, which translates into 4736 KiB saved. The savings here
are from SLUB owner tracking only, because KASAN generic mode still uses
refcounting.
Before:
pools: 893
allocations: 29841
frees: 6524
in_use: 23317
freelist_size: 3454
After:
pools: 597

kasan: guard release_free_meta() shadow access with kasan_arch_is_ready()
release_free_meta() accesses the shadow directly through the path
kasan_slab_free
__kasan_slab_free
kasan_release_object_meta
release_free_meta
kasan_mem_to_shadow
There are no kasan_arch_is_ready() guards here, allowing an oops when the
shadow is not initialized. The oops can be seen on a Power8 KVM guest.
This patch adds the guard to release_free_meta(), as it's the first level
that specifically requires the shadow.
It is safe to put the guard at the start of this function, before the
stack put: only kasan_save_free_info() can initialize the saved stack,
which itself is guarded with kasan_arch_is_ready() by its caller
poison_slab_object(). If the arch becomes ready before
release_free_meta() then we will not observe KASAN_SLAB_FREE_META in the
object's shadow, so we will not put an uninitialized stack either.

mm/damon/lru_sort: fix quota status loss due to online tunings
For online parameters change, DAMON_LRU_SORT creates new schemes based on
latest values of the parameters and replaces the old schemes with the new
one. When creating it, the internal status of the quotas of the old
schemes is not preserved. As a result, charging of the quota starts from
zero after the online tuning. The data that collected to estimate the
throughput of the scheme's action is also reset, and therefore the
estimation should start from the scratch again. Because the throughput
estimation is being used to convert the time quota to the effective size
quota, this could result in temporal time quota inaccuracy. It would be
recovered over time, though. In short, the quota accuracy could be
temporarily degraded after online parameters update.
Fix the problem by checking the case and copying the internal fields for
the status.

'commit_schemes_quota_goals' command handler,
damos_sysfs_set_quota_scores() assumes the number of schemes sysfs

The swapaccount deprecation warning is throwing false positives. Since we

affirmation that always-enabling was the right choice, we certainly don't
want to warn when users request the supported mode.
Only warn when disabling is requested, and clarify the warning.

mm/swap: fix race when skipping swapcache
When skipping swapcache for SWP_SYNCHRONOUS_IO, if two or more threads
swapin the same entry at the same time, they get different pages (A, B).
Before one thread (T0) finishes the swapin and installs page (A) to the
PTE, another thread (T1) could finish swapin of page (B), swap_free the
entry, then swap out the possibly modified page reusing the same entry.
It breaks the pte_same check in (T0) because PTE value is unchanged,
causing ABA problem. Thread (T0) will install a stalled page (A) into the
PTE and cause data corruption.
One possible callstack is like this:
CPU0 CPU1
---- ----
do_swap_page() do_swap_page() with same entry
<direct swapin path> <direct swapin path>
<alloc page A> <alloc page B>
swap_read_folio() <- read to page A swap_read_folio() <- read to page B
<slow on later locks or interrupt> <finished swapin first>
... set_pte_at()
swap_free() <- entry is free
<write to page B, now page A stalled>
<swap out page B to same swap entry>
pte_same() <- Check pass, PTE seems
unchanged, but page A
is stalled!
swap_free() <- page B content lost!
set_pte_at() <- staled page A installed!
And besides, for ZRAM, swap_free() allows the swap device to discard the
entry content, so even if page (B) is not modified, if swap_read_folio()
on CPU0 happens later than swap_free() on CPU1, it may also cause data
loss.
To fix this, reuse swapcache_prepare which will pin the swap entry using
the cache flag, and allow only one thread to swap it in, also prevent any
parallel code from putting the entry in the cache. Release the pin after
PT unlocked.
Racers just loop and wait since it's a rare and very short event. A
schedule_timeout_uninterruptible(1) call is added to avoid repeated page
faults wasting too much CPU, causing livelock or adding too much noise to
perf statistics. A similar livelock issue was described in commit

mm/swap_state: update zswap LRU's protection range with the folio locked
When a folio is swapped in, the protection size of the corresponding zswap
LRU is incremented, so that the zswap shrinker is more conservative with
its reclaiming action. This field is embedded within the struct lruvec,
so updating it requires looking up the folio's memcg and lruvec. However,
currently this lookup can happen after the folio is unlocked, for instance
if a new folio is allocated, and swap_read_folio() unlocks the folio
before returning. In this scenario, there is no stability guarantee for
the binding between a folio and its memcg and lruvec:
* A folio's memcg and lruvec can be freed between the lookup and the
update, leading to a UAF.
* Folio migration can clear the now-unlocked folio's memcg_data, which
directs the zswap LRU protection size update towards the root memcg
instead of the original memcg. This was recently picked up by the
syzbot thanks to a warning in the inlined folio_lruvec() call.
Move the zswap LRU protection range update above the swap_read_folio()
call, and only when a new page is allocated, to prevent this.

mm: zswap: fix missing folio cleanup in writeback race path
In zswap_writeback_entry(), after we get a folio from
__read_swap_cache_async(), we grab the tree lock again to check that the
swap entry was not invalidated and recycled. If it was, we delete the
folio we just added to the swap cache and exit.
However, __read_swap_cache_async() returns the folio locked when it is
newly allocated, which is always true for this path, and the folio is
ref'd. Make sure to unlock and put the folio before returning.
This was discovered by code inspection, probably because this path handles
a race condition that should not happen often, and the bug would not crash
the system, it will only strand the folio indefinitely.

Driver core fixes for 6.8-rc5
Here are some driver core fixes, a kobject fix, and a documentation
update for 6.8-rc5. In detail these changes are:
- devlink fixes for reported issues with 6.8-rc1
- topology scheduling regression fix that has been reported by many
- kobject loosening of checks change in -rc1 is now reverted as some
codepaths seemed to need the checks
- documentation update for the CVE process. Has been reviewed by
many, the last minute change to the document was to bring the .rst
format back into the the new style rules, the contents did not
change.
All of these, except for the documentation update, have been in
linux-next for over a week. The documentation update has been reviewed
for weeks by a group of developers, and in public for a week and the
wording has stabilized for now. If future changes are needed, we can do
so before 6.8-final is out (or anytime after that.)

tracing/probes: Fix to search structure fields correctly
Fix to search a field from the structure which has anonymous union
correctly.
Since the reference `type` pointer was updated in the loop, the search
loop suddenly aborted where it hits an anonymous union. Thus it can not
find the field after the anonymous union. This avoids updating the
cursor `type` pointer in the loop.

* Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if and only

QEMU's global mutex, to the point where the BSP is unable to make forward
progress.
* Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl being

Selftests cleanups and fixes:

* Delete an unused variable in the AMX test (which causes build failures when
compiling with -Werror).
* Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails with an

and the test eventually got skipped).
* Fix TSC related bugs in several Hyper-V selftests.
* Fix a bug in the dirty ring logging test where a sem_post() could be left
pending across multiple runs, resulting in incorrect synchronization between
the main thread and the vCPU worker thread.
* Relax the dirty log split test's assertions on 4KiB mappings to fix false
positives due to the number of mappings for memslot 0 (used for code and

Tracing fixes for v6.8:
- Fix the #ifndef that didn't have CONFIG_ on HAVE_DYNAMIC_FTRACE_WITH_REGS The fix to have dynamic trampolines work with x86 broke arm64 as the config used in the #ifdef was HAVE_DYNAMIC_FTRACE_WITH_REGS and not CONFIG_HAVE_DYNAMIC_FTRACE_WITH_REGS which removed the fix that the previous fix was to fix. - Fix tracing_on state The code to test if "tracing_on" is set used ring_buffer_record_is_on() which returns false if the ring buffer isn't able to be written to. But the ring buffer disable has several bits that disable it. One is internal disabling which is used for resizing and other modifications of the ring buffer. But the "tracing_on" user space visible flag should only report if tracing is actually on and not internally disabled, as this can cause confusion as writing "1" when it is disabled will not enable it. Instead use ring_buffer_record_is_set_on() which shows the user space visible settings. - Fix a false positive kmemleak on saved cmdlines Now that the saved_cmdlines structure is allocated via alloc_page() and not via kmalloc() it has become invisible to kmemleak. The allocation done to one of its pointers was flagged as a dangling allocation leak. Make kmemleak aware of this allocation and free. - Fix synthetic event dynamic strings. A update that cleaned up the synthetic event code removed the return value of trace_string(), and had it return zero instead of the length, causing dynamic strings in the synthetic event to always have zero size. - Clean up documentation and header files for seq_buf -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZc92CxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qiD6AQCCtF9hBWq7slLlBQ+k07hWXOi1h4nR Ae6UmoGlu3u4ugEA6/g8mO2vjABagnK7RSk/R+s1SvSGqWkmAsWeEKirEAY= =Eqjs -----END PGP SIGNATURE----- Merge tag 'trace-v6.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix the #ifndef that didn't have the 'CONFIG_' prefix on HAVE_DYNAMIC_FTRACE_WITH_REGS The fix to have dynamic trampolines work with x86 broke arm64 as the config used in the #ifdef was HAVE_DYNAMIC_FTRACE_WITH_REGS and not CONFIG_HAVE_DYNAMIC_FTRACE_WITH_REGS which removed the fix that the previous fix was to fix. - Fix tracing_on state The code to test if "tracing_on" is set incorrectly used ring_buffer_record_is_on() which returns false if the ring buffer isn't able to be written to.
