Misc driver fix for 6.6-rc4
Here is a single, much requested, fix for a set of misc drivers to resolve a much reported regression in the -rc series that has also propagated back to the stable releases.

eventfs: Test for dentries array allocated in eventfs_release()
The dcache_dir_open_wrapper() could be called when a dynamic event is
being deleted leaving a dentry with no children. In this case the
dlist->dentries array will never be allocated. This needs to be checked
for in eventfs_release(), otherwise it will trigger a NULL pointer
dereference.

tracing/user_events: Align set_bit() address for all archs
All architectures should use a long aligned address passed to set_bit().
User processes can pass either a 32-bit or 64-bit sized value to be
updated when tracing is enabled when on a 64-bit kernel. Both cases are
ensured to be naturally aligned, however, that is not enough. The
address must be long aligned without affecting checks on the value
within the user process which require different adjustments for the bit
for little and big endian CPUs.
Add a compat flag to user_event_enabler that indicates when a 32-bit
value is being used on a 64-bit kernel. Long align addresses and correct
the bit to be used by set_bit() to account for this alignment. Ensure
compat flags are copied during forks and used during deletion clears.

tracing: relax trace_event_eval_update() execution with cond_resched()
When kernel is compiled without preemption, the eval_map_work_func() (which calls trace_event_eval_update()) will not be preempted up to its complete execution. This can actually cause a problem since if another CPU call stop_machine(), the call will have to wait for the eval_map_work_func() function to finish executing in the workqueue before being able to be scheduled. This problem was observe on a SMP system at boot time, when the CPU calling the initcalls executed clocksource_done_booting() which in the end calls stop_machine(). We observed a 1 second delay because one CPU was executing eval_map_work_func() and was not preempted by the stop_machine() task. Adding a call to cond_resched() in trace_event_eval_update() allows other tasks to be executed and thus continue working asynchronously like before without blocking any pending task at boot time.

ring-buffer: Update "shortest_full" in polling
It was discovered that the ring buffer polling was incorrectly stating that read would not block, but that's because polling did not take into account that reads will block if the "buffer-percent" was set. Instead, the ring buffer polling would say reads would not block if there was any data in the ring buffer. This was incorrect behavior from a user space point of view. This was fixed by commit |

=======
The memory hotplug events are notified very quickly and very many, while
the handling of crash hotplug is much slower relatively. So the atomic
variable __kexec_lock and kexec_trylock() can't guarantee the
serialization of crash hotplug handling.
Here, add a new mutex lock __crash_hotplug_lock to serialize crash hotplug
handling specifically. This doesn't impact the usage of __kexec_lock.

While stress-testing zswap a memory corruption was happening when writing

attempting to store a page in zswap, this was because if the store fails
the old entry isn't removed from the tree. This change removes duplicate

arm64: hugetlb: fix set_huge_pte_at() to work with all swap entries
When called with a swap entry that does not embed a PFN (e.g. PTE_MARKER_POISONED or PTE_MARKER_UFFD_WP), the previous implementation of set_huge_pte_at() would either cause a BUG() to fire (if CONFIG_DEBUG_VM is enabled) or cause a dereference of an invalid address and subsequent panic. arm64's huge pte implementation supports multiple huge page sizes, some of which are implemented in the page table with multiple contiguous entries. So set_huge_pte_at() needs to work out how big the logical pte is, so that it can also work out how many physical ptes (or pmds) need to be written. It previously did this by grabbing the folio out of the pte and querying its size. However, there are cases when the pte being set is actually a swap entry. But this also used to work fine, because for huge ptes, we only ever saw migration entries and hwpoison entries. And both of these types of swap entries have a PFN embedded, so the code would grab that and everything still worked out. But over time, more calls to set_huge_pte_at() have been added that set swap entry types that do not embed a PFN. And this causes the code to go bang. The triggering case is for the uffd poison test, commit |

mm: hugetlb: add huge page size param to set_huge_pte_at()
Patch series "Fix set_huge_pte_at() panic on arm64", v2. This series fixes a bug in arm64's implementation of set_huge_pte_at(), which can result in an unprivileged user causing a kernel panic. The problem was triggered when running the new uffd poison mm selftest for HUGETLB memory. This test (and the uffd poison feature) was merged for v6.5-rc7. Ideally, I'd like to get this fix in for v6.6 and I've cc'ed stable (correctly this time) to get it backported to v6.5, where the issue first showed up.

maple_tree: add MAS_UNDERFLOW and MAS_OVERFLOW states
When updating the maple tree iterator to avoid rewalks, an issue was
introduced when shifting beyond the limits. This can be seen by trying to
go to the previous address of 0, which would set the maple node to
MAS_NONE and keep the range as the last entry.
Subsequent calls to mas_find() would then search upwards from mas->last
and skip the value at mas->index/mas->last. This showed up as a bug in
mprotect which skips the actual VMA at the current range after attempting
to go to the previous VMA from 0.
Since MAS_NONE may already be set when searching for a value that isn't
contained within a node, changing the handling of MAS_NONE in mas_find()
would make the code more complicated and error prone. Furthermore, there
was no way to tell which limit was hit, and thus which action to take
(next or the entry at the current range).
This solution is to add two states to track what happened with the
previous iterator action. This allows for the expected behaviour of the
next command to return the correct item (either the item at the range
requested, or the next/previous).
Tests are also added and updated accordingly.

maple_tree: add mas_is_active() to detect in-tree walks
Patch series "maple_tree: Fix mas_prev() state regression". Pedro Falcato retported an mprotect regression [1] which was bisected back to the iterator changes for maple tree. Root cause analysis showed the mas_prev() running off the end of the VMA space (previous from 0) followed by mas_find(), would skip the first value. This patchset introduces maple state underflow/overflow so the sequence of calls on the maple state will return what the user expects. Users who encounter this bug may see mprotect(), userfaultfd_register(), and mlock() fail on VMAs mapped with address 0. This patch (of 2): Instead of constantly checking each possibility of the maple state, create a fast path that will skip over checking unlikely states.

nilfs2: fix potential use after free in nilfs_gccache_submit_read_data()
In nilfs_gccache_submit_read_data(), brelse(bh) is called to drop the
reference count of bh when the call to nilfs_dat_translate() fails. If
the reference count hits 0 and its owner page gets unlocked, bh may be
freed. However, bh->b_page is dereferenced to put the page after that,
which may result in a use-after-free bug. This patch moves the release
operation after unlocking and putting the page.
NOTE: The function in question is only called in GC, and in combination
with current userland tools, address translation using DAT does not occur
in that function, so the code path that causes this issue will not be
executed. However, it is possible to run that code path by intentionally
modifying the userland GC library or by calling the GC ioctl directly.

mm: report success more often from filemap_map_folio_range()
Even though we had successfully mapped the relevant page, we would rarely
return success from filemap_map_folio_range(). That leads to falling back
from the VMA lock path to the mmap_lock path, which is a speed &
scalability issue. Found by inspection.

fs: binfmt_elf_efpic: fix personality for ELF-FDPIC
The elf-fdpic loader hard sets the process personality to either
PER_LINUX_FDPIC for true elf-fdpic binaries or to PER_LINUX for normal ELF
binaries (in this case they would be constant displacement compiled with
-pie for example). The problem with that is that it will lose any other
bits that may be in the ELF header personality (such as the "bug
emulation" bits).
On the ARM architecture the ADDR_LIMIT_32BIT flag is used to signify a
normal 32bit binary - as opposed to a legacy 26bit address binary. This
matters since start_thread() will set the ARM CPSR register as required
based on this flag. If the elf-fdpic loader loses this bit the process
will be mis-configured and crash out pretty quickly.
Modify elf-fdpic loader personality setting so that it preserves the upper
three bytes by using the SET_PERSONALITY macro to set it. This macro in
the generic case sets PER_LINUX and preserves the upper bytes.
Architectures can override this for their specific use case, and ARM does
exactly this.
The problem shows up quite easily running under qemu using the ARM
architecture, but not necessarily on all types of real ARM hardware. If
the underlying ARM processor does not support the legacy 26-bit addressing
mode then everything will work as expected.

ATA fixes for 6.6-rc4
A larger than usual set of fixes for 6.6-rc4 due to the unexpected
number of fixes needed to address ATA disks suspend/resume issues.
In more details:
- Add missing additionalProperties on child nodes to the pata-common DT
bindings (Rob).
- Fix handling of the REPORT SUPPORTED OPERATION CODES command to
ignore reserved bits (Niklas).
- Increase port multiplier soft reset timeout to accomodate slow
devices and avoid issues on wakeup (Matthias).
- A couple of minor code fixes to avoid compilation warnings in
libata-core and libata-eh (me).
- Many patches from me to address suspend/resume issues, and in
particular a potential deadlock on resume due to the SCSI disk driver
resume operation not being synchronized with libata EH port resume
handling. This is addressed by changing the scsi disk driver disk
start/stop control to allow libata to execute disk suspend (spin
down) and resume (spin up) on its own during system suspend/resume.
Runtime suspend/resume control remains with the SCSI disk driver.
Other fixes include:
- Fix libata power management request issuing to avoid races.
- Establish a link between ATA ports and SCSI devices to order PM
operations.
- Fix device removal to avoid issues with driver rmmod removal.
- Fix synchronization of libata device rescan and SCSI disk resume
operation.
- Remove libsas PM operations as suspend/resume is handled directly
by the sas controller resume.
- Fix the SCSI disk driver to not issue commands to suspended disks,
thus avoiding potential system lock-up on resume.

- Fix the parent name of a clk in the Spreadtrum ums512 clk driver
- Fix a suspend/resume issue in Skyworks Si521xx clk driver where
regmap restoration fails because writes are wedged

io_uring/fs: remove sqe->rw_flags checking from LINKAT
This is unionized with the actual link flags, so they can of course be
set and they will be evaluated further down. If not we fail any LINKAT
that has to set option flags.

x86/sgx: Resolves SECS reclaim vs. page fault for EAUG race
The SGX EPC reclaimer (ksgxd) may reclaim the SECS EPC page for an
enclave and set secs.epc_page to NULL. The SECS page is used for EAUG
and ELDU in the SGX page fault handler. However, the NULL check for
secs.epc_page is only done for ELDU, not EAUG before being used.
Fix this by doing the same NULL check and reloading of the SECS page as
needed for both EAUG and ELDU.
The SECS page holds global enclave metadata. It can only be reclaimed
when there are no other enclave pages remaining. At that point,
virtually nothing can be done with the enclave until the SECS page is
paged back in.
An enclave can not run nor generate page faults without a resident SECS
page. But it is still possible for a #PF for a non-SECS page to race
with paging out the SECS page: when the last resident non-SECS page A
triggers a #PF in a non-resident page B, and then page A and the SECS
both are paged out before the #PF on B is handled.
Hitting this bug requires that race triggered with a #PF for EAUG.
Following is a trace when it happens.
