05c56e7b43 kasan: fix type cast in memory_is_poisoned_n
Commit bb6e04a173 ("kasan: use internal prototypes matching gcc-13
builtins") introduced a bug into the memory_is_poisoned_n implementation:
it effectively removed the cast to a signed integer type after applying
KASAN_GRANULE_MASK.

As a result, KASAN started failing to properly check memset, memcpy, and
other similar functions.

Fix the bug by adding the cast back (through an additional signed integer
variable to make the code more readable).

I am going to lose my vrull.eu address at the end of july, and while
adding it to mailmap I also realised that there are more old addresses
from me dangling, so update .mailmap for all of them.

ddcd91f4cb mailmap: update manpage link
Patch series "Update .mailmap for my work address and fix manpage".

While updating mailmap for the going-away address, I also found that on
current systems the manpage linked from the header comment changed.

And in fact it looks like the git mailmap feature got its own manpage.


This patch (of 2):

On recent systems the git-shortlog manpage only tells people to
    See gitmailmap(5)

So instead of sending people on a scavenger hunt, put that info into the
header directly.  Though keep the old reference around for older systems.

028725e733 bootmem: remove the vmemmap pages from kmemleak in free_bootmem_page
commit dd0ff4d12d ("bootmem: remove the vmemmap pages from kmemleak in
put_page_bootmem") fix an overlaps existing problem of kmemleak.  But the
problem still existed when HAVE_BOOTMEM_INFO_NODE is disabled, because in
this case, free_bootmem_page() will call free_reserved_page() directly.

Fix the problem by adding kmemleak_free_part() in free_bootmem_page() when
HAVE_BOOTMEM_INFO_NODE is disabled.

8344a3d44b writeback: account the number of pages written back
nr_to_write is a count of pages, so we need to decrease it by the number
of pages in the folio we just wrote, not by 1.  Most callers specify
either LONG_MAX or 1, so are unaffected, but writeback_sb_inodes() might
end up writing 512x as many pages as it asked for.

Dave added:

: XFS is the only filesystem this would affect, right?  AFAIA, nothing
: else enables large folios and uses writeback through
: write_cache_pages() at this point...
: 
: In which case, I'd be surprised if much difference, if any, gets
: noticed by anyone.

6dca4ac6fc mm: call arch_swap_restore() from do_swap_page()
Commit c145e0b47c ("mm: streamline COW logic in do_swap_page()") moved
the call to swap_free() before the call to set_pte_at(), which meant that
the MTE tags could end up being freed before set_pte_at() had a chance to
restore them.  Fix it by adding a call to the arch_swap_restore() hook
before the call to swap_free().

08bab74ae6 squashfs: fix cache race with migration
Migration replaces the page in the mapping before copying the contents and
the flags over from the old page, so check that the page in the page cache
is really up to date before using it.  Without this, stressing squashfs
reads with parallel compaction sometimes results in squashfs reporting
data corruption.

191fcdb6c9 mm/hugetlb.c: fix a bug within a BUG(): inconsistent pte comparison
The following crash happens for me when running the -mm selftests (below).
Specifically, it happens while running the uffd-stress subtests:

That happens because a BUG() statement in huge_pte_alloc() attempts to
check that a pte, if present, is a hugetlb pte, but it does so in a
non-lockless-safe manner that leads to a false BUG() report.

We got here due to a couple of bugs, each of which by itself was not quite
enough to cause a problem:

First of all, before commit c33c794828f2("mm: ptep_get() conversion"), the
BUG() statement in huge_pte_alloc() was itself fragile: it relied upon
compiler behavior to only read the pte once, despite using it twice in the
same conditional.

Next, commit c33c794828 ("mm: ptep_get() conversion") broke that
delicate situation, by causing all direct pte reads to be done via
READ_ONCE().  And so READ_ONCE() got called twice within the same BUG()
conditional, leading to comparing (potentially, occasionally) different
versions of the pte, and thus to false BUG() reports.

Fix this by taking a single snapshot of the pte before using it in the
BUG conditional.

Now, that commit is only partially to blame here but, people doing
bisections will invariably land there, so this will help them find a fix
for a real crash.  And also, the previous behavior was unlikely to ever
expose this bug--it was fragile, yet not actually broken.

So that's why I chose this commit for the Fixes tag, rather than the
commit that created the original BUG() statement.

2b4f3b4987 fork: lock VMAs of the parent process when forking
Patch series "Avoid memory corruption caused by per-VMA locks", v4.

A memory corruption was reported in [1] with bisection pointing to the
patch [2] enabling per-VMA locks for x86.  Based on the reproducer
provided in [1] we suspect this is caused by the lack of VMA locking while
forking a child process.

Patch 1/2 in the series implements proper VMA locking during fork.  I
tested the fix locally using the reproducer and was unable to reproduce
the memory corruption problem.

This fix can potentially regress some fork-heavy workloads.  Kernel build
time did not show noticeable regression on a 56-core machine while a
stress test mapping 10000 VMAs and forking 5000 times in a tight loop
shows ~7% regression.  If such fork time regression is unacceptable,
disabling CONFIG_PER_VMA_LOCK should restore its performance.  Further
optimizations are possible if this regression proves to be problematic.

Patch 2/2 disables per-VMA locks until the fix is tested and verified.


This patch (of 2):

When forking a child process, parent write-protects an anonymous page and
COW-shares it with the child being forked using copy_present_pte(). 
Parent's TLB is flushed right before we drop the parent's mmap_lock in
dup_mmap().  If we get a write-fault before that TLB flush in the parent,
and we end up replacing that anonymous page in the parent process in
do_wp_page() (because, COW-shared with the child), this might lead to some
stale writable TLB entries targeting the wrong (old) page.  Similar issue
happened in the past with userfaultfd (see flush_tlb_page() call inside
do_wp_page()).

Lock VMAs of the parent process when forking a child, which prevents
concurrent page faults during fork operation and avoids this issue.  This
fix can potentially regress some fork-heavy workloads.  Kernel build time
did not show noticeable regression on a 56-core machine while a stress
test mapping 10000 VMAs and forking 5000 times in a tight loop shows ~7%
regression.  If such fork time regression is unacceptable, disabling
CONFIG_PER_VMA_LOCK should restore its performance.  Further optimizations
are possible if this regression proves to be problematic.

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

956578e3d3 NTB: EPF: fix possible memory leak in pci_vntb_probe()
As ntb_register_device() don't handle error of device_register(),
if ntb_register_device() returns error in pci_vntb_probe(), name of kobject
which is allocated in dev_set_name() called in device_add() is leaked.

As comment of device_add() says, it should call put_device() to drop the
reference count that was set in device_initialize()
when it fails, so the name can be freed in kobject_cleanup().

8623ccbfc5 NTB: ntb_transport: fix possible memory leak while device_register() fails
If device_register() returns error, the name allocated by
dev_set_name() need be freed. As comment of device_register()
says, it should use put_device() to give up the reference in
the error path. So fix this by calling put_device(), then the
name can be freed in kobject_cleanup(), and client_dev is freed
in ntb_transport_client_release().

A problem about ntb_hw_intel create debugfs failed is triggered with the

The reason is that intel_ntb_pci_driver_init() returns
pci_register_driver() directly without checking its return value, if
pci_register_driver() failed, it returns without destroy the newly created

b1472a60a5 x86/smp: Don't send INIT to boot CPU
Parking CPUs in INIT works well, except for the crash case when the CPU
which invokes smp_park_other_cpus_in_init() is not the boot CPU. Sending
INIT to the boot CPU resets the whole machine.

Prevent this by validating that this runs on the boot CPU. If not fall back
and let CPUs hang in HLT.

8066178f53 Tracing fixes for 6.5:
- Fix bad git merge of #endif in arm64 code
   A merge of the arm64 tree caused #endif to go into the wrong place
 
 - Fix crash on lseek of write access to tracefs/error_log
   Opening error_log as write only, and then doing an lseek() causes
   a kernel panic, because the lseek() handle expects a "seq_file"
   to exist (which is not done on write only opens). Use tracing_lseek()
   that tests for this instead of calling the default seq lseek handler.
 
 - Check for negative instead of -E2BIG for error on strscpy() returns
   Instead of testing for -E2BIG from strscpy(), to be more robust,
   check for less than zero, which will make sure it catches any error
   that strscpy() may someday return.

Pull vfs fixes from Christian Brauner:
 "This contains two minor fixes for Jan's rename locking work:

   - Unlocking the source inode was guarded by a check whether source
     was non-NULL. This doesn't make sense because source must be
     non-NULL and the commit message explains in detail why

   - The lock_two_nondirectories() helper called WARN_ON_ONCE() and
     dereferenced the inodes unconditionally but the underlying
     lock_two_inodes() helper and the kernel documentation for that
     function are clear that it is valid to pass NULL arguments, so a
     non-NULL check is needed. No callers currently pass NULL arguments
     but let's not knowingly leave landmines around"

  fs: don't assume arguments are non-NULL
  fs: no need to check source
