userfaultfd: fix a crash in UFFDIO_MOVE when PMD is a migration entry
When UFFDIO_MOVE encounters a migration PMD entry, it proceeds with
obtaining a folio and accessing it even though the entry is swp_entry_t.
Add the missing check and let split_huge_pmd() handle migration entries.
While at it also remove unnecessary folio check.
[surenb@google.com: remove extra folio check, per David]

mm: pass page directly instead of using folio_page
In commit_anon_folio_batch(), we iterate over all pages pointed to by the
PTE batch. Therefore we need to know the first page of the batch;
currently we derive that via folio_page(folio, 0), but, that takes us to
the first (head) page of the folio instead - our PTE batch may lie in the
middle of the folio, leading to incorrectness.
Bite the bullet and throw away the micro-optimization of reusing the folio
in favour of code simplicity. Derive the page and the folio in
change_pte_range, and pass the page too to commit_anon_folio_batch to fix
the aforementioned issue.

selftests/proc: fix string literal warning in proc-maps-race.c
This change resolves non literal string format warning invoked for
proc-maps-race.c while compiling.
proc-maps-race.c:205:17: warning: format not a string literal and no format arguments [-Wformat-security]
205 | printf(text);
| ^~~~~~
proc-maps-race.c:209:17: warning: format not a string literal and no format arguments [-Wformat-security]
209 | printf(text);
| ^~~~~~
proc-maps-race.c: In function `print_last_lines':
proc-maps-race.c:224:9: warning: format not a string literal and no format arguments [-Wformat-security]
224 | printf(start);
| ^~~~~~
Add string format specifier %s for the printf calls in both
print_first_lines() and print_last_lines() thus resolving the warnings.
The test executes fine after this change thus causing no effect to the
functional behavior of the test.

mm/smaps: fix race between smaps_hugetlb_range and migration
smaps_hugetlb_range() handles the pte without holdling ptl, and may be
concurrenct with migration, leaing to BUG_ON in pfn_swap_entry_to_page().
The race is as follows.
smaps_hugetlb_range migrate_pages
huge_ptep_get
remove_migration_ptes
folio_unlock
pfn_swap_entry_folio
BUG_ON
To fix it, hold ptl lock in smaps_hugetlb_range().

mm: fix the race between collapse and PT_RECLAIM under per-vma lock
The check_pmd_still_valid() call during collapse is currently only
protected by the mmap_lock in write mode, which was sufficient when
pt_reclaim always ran under mmap_lock in read mode. However, since
madvise_dontneed can now execute under a per-VMA lock, this assumption is
no longer valid. As a result, a race condition can occur between collapse
and PT_RECLAIM, potentially leading to a kernel panic.

mm/kmemleak: avoid soft lockup in __kmemleak_do_cleanup()
A soft lockup warning was observed on a relative small system x86-64 system with 16 GB of memory when running a debug kernel with kmemleak enabled. watchdog: BUG: soft lockup - CPU#8 stuck for 33s! [kworker/8:1:134] The test system was running a workload with hot unplug happening in parallel. Then kemleak decided to disable itself due to its inability to allocate more kmemleak objects. The debug kernel has its CONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE set to 40,000. The soft lockup happened in kmemleak_do_cleanup() when the existing kmemleak objects were being removed and deleted one-by-one in a loop via a workqueue. In this particular case, there are at least 40,000 objects that need to be processed and given the slowness of a debug kernel and the fact that a raw_spinlock has to be acquired and released in __delete_object(), it could take a while to properly handle all these objects. As kmemleak has been disabled in this case, the object removal and deletion process can be further optimized as locking isn't really needed. However, it is probably not worth the effort to optimize for such an edge case that should rarely happen. So the simple solution is to call cond_resched() at periodic interval in the iteration loop to avoid soft lockup.

mm/kmemleak: avoid deadlock by moving pr_warn() outside kmemleak_lock
When netpoll is enabled, calling pr_warn_once() while holding
kmemleak_lock in mem_pool_alloc() can cause a deadlock due to lock
inversion with the netconsole subsystem. This occurs because
pr_warn_once() may trigger netpoll, which eventually leads to
__alloc_skb() and back into kmemleak code, attempting to reacquire
kmemleak_lock.
This is the path for the deadlock.
mem_pool_alloc()
-> raw_spin_lock_irqsave(&kmemleak_lock, flags);
-> pr_warn_once()
-> netconsole subsystem
-> netpoll
-> __alloc_skb
-> __create_object
-> raw_spin_lock_irqsave(&kmemleak_lock, flags);
Fix this by setting a flag and issuing the pr_warn_once() after
kmemleak_lock is released.

kasan/test: fix protection against compiler elision
The kunit test is using assignments to
"static volatile void *kasan_ptr_result" to prevent elision of memory
loads, but that's not working:
In this variable definition, the "volatile" applies to the "void", not to
the pointer.
To make "volatile" apply to the pointer as intended, it must follow
after the "*".
This makes the kasan_memchr test pass again on my system. The
kasan_strings test is still failing because all the definitions of
load_unaligned_zeropad() are lacking explicit instrumentation hooks and
ASAN does not instrument asm() memory operands.

f2fs-for-6.17-rc1
In this round, we've mainly updated three parts: 1) folio conversion by Matthew, 2) switch to a new mount API by Hongbo and Eric, and 3) several sysfs entries to tune GCs for ZUFS with finer granularity by Daeho. There are also patches to address bugs and issues in the existing features such as GCs, file pinning, write-while-dio-read, contingous block allocation, and memory access violations. Enhancement: - switch to new mount API and folio conversion - add sysfs nodes to controle F2FS GCs for ZUFS - improve performance on the nat entry cache - drop inode from the donation list when the last file is closed - avoid splitting bio when reading multiple pages Bug fix: - fix to trigger foreground gc during f2fs_map_blocks() in lfs mode - make sure zoned device GC to use FG_GC in shortage of free section - fix to calculate dirty data during has_not_enough_free_secs() - fix to update upper_p in __get_secs_required() correctly - wait for inflight dio completion, excluding pinned files read using dio - don't break allocation when crossing contiguous sections - vm_unmap_ram() may be called from an invalid context - fix to avoid out-of-boundary access in dnode page - fix to avoid panic in f2fs_evict_inode - fix to avoid UAF in f2fs_sync_inode_meta() - fix to use f2fs_is_valid_blkaddr_raw() in do_write_page() - fix UAF of f2fs_inode_info in f2fs_free_dic - fix to avoid invalid wait context issue - fix bio memleak when committing super block - handle nat.blkaddr corruption in f2fs_get_node_info() In addition, there are also clean-ups and minor bug fixes. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmiRJ+oACgkQQBSofoJI UNInMA//ekJJCf/0UyMYiPA9ag4KBb/VA0VaVJbw6BA/DoT5ZII6+lCIfllyELbk 78+ZppTrKq5OyImwiajcNijEwyDbh/asfUu+uNVsC85fjoboiBgDGVHbUEtSQ20Q 5JVXIL5PhDDVGdVNPh57ijYK/PxhzBPaFNuaGECYrqnWhkQEb//HmN20KRfzcOjZ 19QnOyEh0HED/izMjLhtZaCBQP53kfB7VjhTxMdY86l6IZ22gJHPRrnqBQHRTfyb iHcMJj4WRd7SpvbD/6bSdnUfpxOYPIm3GwQHdG46cHBEH1scnyQxx2OULlSLUbz6 yeiG36jcuQQWOev8ikBjNzfAozD0VvUAulPpfIbAoHc5jBYkA1sP3N7JOiao1H4Z FnPgw/FyIQE+d9NkbyeVW+6f9WfmKlJlIJ4zKoURbZvARYCZKmiPiI9vPWWe18qV nchWniQMJ45TYsABUGmGJwTEe/SFaOkgLpLjAlzCy7ZY9/6LKVUlnxR0E1ZDcjSp 5/E5fXQhds0Nn7F1jQXV3afxkECW+MNOLS/31ggL+ym6Pce3HPJCxBeRU4XaKrvA O0wP7n3g5jhVVWce0PBghF0mwTVVBwohTaUhL7lIIJMxKGkr4A8kH1j8tLLBdD3b hqcesDCtqqOZhogbwHXEgUDSikak4/1R1gDXnK0KhL1gg0Z6wR4= =XIPU -----END PGP SIGNATURE----- Merge tag 'f2fs-for-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "Three main updates: folio conversion by Matthew, switch to a new mount API by Hongbo and Eric, and several sysfs entries to tune GCs for ZUFS with finer granularity by Daeho.

Pull apparmor updates from John Johansen:
"This has one major feature, it pulls in a cleaned up version of
af_unix mediation that Ubuntu has been carrying for years. It is
placed behind a new abi to ensure that it does cause policy
regressions. With pulling in the af_unix mediation there have been
cleanups and some refactoring of network socket mediation. This
accounts for the majority of the changes in the diff.
In addition there are a few improvements providing minor code
optimizations. several code cleanups, and bug fixes.
Features:
- improve debug printing
- carry mediation check on label (optimization)
- improve ability for compiler to optimize

apparmor: fix: oops when trying to free null ruleset
profile allocation is wrongly setting the number of entries on the
rules vector before any ruleset is assigned. If profile allocation
fails between ruleset allocation and assigning the first ruleset,
free_ruleset() will be called with a null pointer resulting in an
oops.

Significant patch series in this pull request:
- The 2 patch series "squashfs: Remove page->mapping references" from
Matthew Wilcox gets us closer to being able to remove page->mapping.
- The 5 patch series "relayfs: misc changes" from Jason Xing does some
maintenance and minor feature addition work in relayfs.
- The 5 patch series "kdump: crashkernel reservation from CMA" from Jiri
Bohac switches us from static preallocation of the kdump crashkernel's
working memory over to dynamic allocation. So the difficulty of
a-priori estimation of the second kernel's needs is removed and the
first kernel obtains extra memory.
- The 5 patch series "generalize panic_print's dump function to be used
by other kernel parts" from Feng Tang implements some consolidation and
rationalizatio of the various ways in which a faiing kernel splats
information at the operator.

tracing cleanups for v6.17:
- Remove unneeded goto out statements
Over time, the logic was restructured but left a "goto out" where the
out label simply did a "return ret;". Instead of jumping to this out
label, simply return immediately and remove the out label.
- Add guard(ring_buffer_nest)
Some calls to the tracing ring buffer can happen when the ring buffer is
already being written to at the same context (for example, a
trace_printk() in between a ring_buffer_lock_reserve() and a
ring_buffer_unlock_commit()).
In order to not trigger the recursion detection, these functions use
ring_buffer_nest_start() and ring_buffer_nest_end(). Create a guard() for
these functions so that their use cases can be simplified and not need to
use goto for the release.
- Clean up the tracing code with guard() and __free() logic
There were several locations that were prime candidates for using guard()
and __free() helpers. Switch them over to use them.
- Fix output of function argument traces for unsigned int values
The function tracer with "func-args" option set will record up to 6 argument
registers and then use BTF to format them for human consumption when the
trace file is read. There's several arguments that are "unsigned long" and
even "unsigned int" that are either and address or a mask. It is easier to
understand if they were printed using hexadecimal instead of decimal.
The old method just printed all non-pointer values as signed integers,
which made it even worse for unsigned integers.
For instance, instead of:
__local_bh_disable_ip(ip=-2127311112, cnt=256) <-handle_softirqs
Show:
__local_bh_disable_ip(ip=0xffffffff8133cef8, cnt=0x100) <-handle_softirqs

This is a small set of changes for modules, primarily to extend module users
to use the module data structures in combination with the already no-op stub module functions, even when support for modules is disabled in the kernel configuration. This change follows the kernel's coding style for conditional compilation and allows kunit code to drop all CONFIG_MODULES ifdefs, which is also part of the changes. This should allow others part of the kernel to do the same cleanup. Note that this had a conflict with sysctl changes [1] but should be fixed now as I rebased on top. The remaining changes include a fix for module name length handling which could potentially lead to the removal of an incorrect module, and various cleanups. The module name fix and related cleanup has been in linux-next since Thursday (July 31) while the rest of the changes for a bit more than 3 weeks. Note that this currently has conflicts in next with kbuild's tree [2].

'as_ptr_cast_mut', 'as_underscore', 'cast_lossless' and 'ref_as_ptr'.
These are intended to avoid type casts with the 'as' operator, which
are quite powerful, into restricted variants that are less powerful
and thus should help to avoid mistakes.
- Remove the 'author' key now that most instances were moved to the
plural one in the previous cycle.
'kernel' crate:
- New 'bug' module: add 'warn_on!' macro which reuses the existing
'BUG'/'WARN' infrastructure, i.e. it respects the usual sysctls and
kernel parameters:
warn_on!(value == 42);
To avoid duplicating the assembly code, the same strategy is followed
as for the static branch code in order to share the assembly between
both C and Rust. This required a few rearrangements on C arch headers
-- the existing C macros should still generate the same outputs, thus
no functional change expected there.
- 'workqueue' module: add delayed work items, including a 'DelayedWork'
struct, a 'impl_has_delayed_work!' macro and an 'enqueue_delayed'
method, e.g.:
/// Enqueue the struct for execution on the system workqueue,
/// where its value will be printed 42 jiffies later.
fn print_later(value: Arc<MyStruct>) {
let _ = workqueue::system().enqueue_delayed(value, 42);
}
- New 'bits' module: add support for 'bit' and 'genmask' functions,
with runtime- and compile-time variants, e.g.:
static_assert!(0b00010000 == bit_u8(4));
static_assert!(0b00011110 == genmask_u8(1..=4));
assert!(checked_bit_u32(u32::BITS).is_none());
- 'uaccess' module: add 'UserSliceReader::strcpy_into_buf', which reads
NUL-terminated strings from userspace into a '&CStr'.
Introduce 'UserPtr' newtype, similar in purpose to '__user' in C, to
minimize mistakes handling userspace pointers, including mixing them
up with integers and leaking them via the 'Debug' trait. Add it to
the prelude, too.
- Start preparations for the replacement of our custom 'CStr' type
with the analogous type in the 'core' standard library. This will
take place across several cycles to make it easier. For this one,
it includes a new 'fmt' module, using upstream method names and some
other cleanups.
Replace 'fmt!' with a re-export, which helps Clippy lint properly,
and clean up the found 'uninlined-format-args' instances.
- 'dma' module:
- Clarify wording and be consistent in 'coherent' nomenclature.
- Convert the 'read!()' and 'write!()' macros to return a 'Result'.
- Add 'as_slice()', 'write()' methods in 'CoherentAllocation'.
- Expose 'count()' and 'size()' in 'CoherentAllocation' and add the
corresponding type invariants.
- Implement 'CoherentAllocation::dma_handle_with_offset()'.
- 'time' module:
- Make 'Instant' generic over clock source. This allows the compiler
to assert that arithmetic expressions involving the 'Instant' use
'Instants' based on the same clock source.
- Make 'HrTimer' generic over the timer mode. 'HrTimer' timers take a
'Duration' or an 'Instant' when setting the expiry time, depending
on the timer mode. With this change, the compiler can check the
type matches the timer mode.
- Add an abstraction for 'fsleep'. 'fsleep' is a flexible sleep
function that will select an appropriate sleep method depending on
the requested sleep time.
- Avoid 64-bit divisions on 32-bit hardware when calculating
timestamps.
- Seal the 'HrTimerMode' trait. This prevents users of the
'HrTimerMode' from implementing the trait on their own types.
- Pass the correct timer mode ID to 'hrtimer_start_range_ns()'.
- 'list' module: remove 'OFFSET' constants, allowing to remove pointer
arithmetic; now 'impl_list_item!' invokes 'impl_has_list_links!' or
'impl_has_list_links_self_ptr!'. Other simplifications too.
- 'types' module: remove 'ForeignOwnable::PointedTo' in favor of a
constant, which avoids exposing the type of the opaque pointer, and
require 'into_foreign' to return non-null.
Remove the 'Either<L, R>' type as well. It is unused, and we want to
encourage the use of custom enums for concrete use cases.
- 'sync' module: implement 'Borrow' and 'BorrowMut' for 'Arc' types
to allow them to be used in generic APIs.
- 'alloc' module: implement 'Borrow' and 'BorrowMut' for 'Box<T, A>';
and 'Borrow', 'BorrowMut' and 'Default' for 'Vec<T, A>'.
- 'Opaque' type: add 'cast_from' method to perform a restricted cast
that cannot change the inner type and use it in callers of
'container_of!'. Rename 'raw_get' to 'cast_into' to match it.
- 'rbtree' module: add 'is_empty' method.
- 'sync' module: new 'aref' submodule to hold 'AlwaysRefCounted' and
'ARef', which are moved from the too general 'types' module which we
want to reduce or eventually remove. Also fix a safety comment in
'static_lock_class'.
'pin-init' crate:
- Add 'impl<T, E> [Pin]Init<T, E> for Result<T, E>', so results are now
(pin-)initializers.
- Add 'Zeroable::init_zeroed()' that delegates to 'init_zeroed()'.
- New 'zeroed()', a safe version of 'mem::zeroed()' and also provide
it via 'Zeroable::zeroed()'.
- Implement 'Zeroable' for 'Option<&T>', 'Option<&mut T>' and for
'Option<[unsafe] [extern "abi"] fn(...args...) -> ret>' for '"Rust"'
and '"C"' ABIs and up to 20 arguments.
- Changed blanket impls of 'Init' and 'PinInit' from 'impl<T, E>
[Pin]Init<T, E> for T' to 'impl<T> [Pin]Init<T> for T'.
- Renamed 'zeroed()' to 'init_zeroed()'.
- Upstream dev news: improve CI more to deny warnings, use
'--all-targets'. Check the synchronization status of the two '-next'
branches in upstream and the kernel.

When the first driver for Apple Silicon was upstreamed we accidentally included `default ARCH_APPLE` in its Kconfig which then spread to almost every subsequent driver. As soon as ARCH_APPLE is set to y this will pull in many drivers as built-ins which is not what we want. Thus, drop `default ARCH_APPLE` from Kconfig.
