A race condition may occur if the user calls close() on another thread during a write() operation on the device node of the efi capsule. This is a race condition that occurs between the efi_capsule_write() and efi_capsule_flush() functions of efi_capsule_fops, which ultimately results in UAF. So, the page freeing process is modified to be done in efi_capsule_release() instead of efi_capsule_flush().

When trying to get a file lock on an AFS file, the server may return UAEAGAIN to indicate that the lock is already held. This is currently translated by the default path to -EREMOTEIO.

Actually, 'compressedlcs' stores compressed block count rather than lcluster count. Therefore, the number of bits for shifting the count should be 'LOG_BLOCK_SIZE' rather than 'lclusterbits' although current lcluster size is 4K. The value of 'm_plen' will be wrong once we enable the non 4K-sized lcluster.

-Wformat was recently re-enabled for builds with clang, then quickly re-disabled, due to concerns stemming from the frequency of default argument promotion related warning instances. commit 258fafcd ("Makefile.extrawarn: re-enable -Wformat for clang") commit 21f9c8a1 ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"") ISO WG14 has ratified N2562 to address default argument promotion explicitly for printf, as part of the upcoming ISO C2X standard. The behavior of clang was changed in clang-16 to not warn for the cited cases in all language modes. Add a version check, so that users of clang-16 now get the full effect of -Wformat. For older clang versions, re-enable flags under the -Wformat group that way users still get some useful checks related to format strings, without noisy default argument promotion warnings. I intentionally omitted -Wformat-y2k and -Wformat-security from being re-enabled, which are also part of -Wformat in clang-16.

The mmap lock protects the page walker from changes to the page tables during the walk. However a read lock is insufficient to protect those areas which don't have a VMA as munmap() detaches the VMAs before downgrading to a read lock and actually tearing down PTEs/page tables. For users of walk_page_range() the solution is to simply call pte_hole() immediately without checking the actual page tables when a VMA is not present. We now never call __walk_page_range() without a valid vma. For walk_page_range_novma() the locking requirements are tightened to require the mmap write lock to be taken, and then walking the pgd directly with 'no_vma' set. This in turn means that all page walkers either have a valid vma, or it's that special 'novma' case for page table debugging. As a result, all the odd '(!walk->vma && !walk->no_vma)' tests can be removed.

LoongArch hasn't been upstream yet at that time and can be still built successfully without adjustment because this function has a weak version with the correct prototype.

Ensure that all input sections are listed explicitly in the linker script, and issue a warning otherwise. This ensures that the binary image matches the PE/COFF and other image metadata exactly, which is important for things like code signing.

Pull io_uring fixes from Jens Axboe: - A single fix for over-eager retries for networking (Pavel) - Revert the notification slot support for zerocopy sends. It turns out that even after more than a year or development and testing, there's not full agreement on whether just using plain ordered notifications is Good Enough to avoid the complexity of using the notifications slots. Because of that, we decided that it's best left to a future final decision. We can always bring back this feature, but we can't really change it or remove it once we've released 6.0 with it enabled. The reverts leave the usual CQE notifications as the primary interface for knowing when data was sent, and when it was acked.

Pull landlock fix from Mickaël Salaün: "This fixes a mis-handling of the LANDLOCK_ACCESS_FS_REFER right when multiple rulesets/domains are stacked. The expected behaviour was that an additional ruleset can only restrict the set of permitted operations, but in this particular case, it was potentially possible to re-gain the LANDLOCK_ACCESS_FS_REFER right" * tag 'landlock-6.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: landlock: Fix file reparenting without explicit LANDLOCK_ACCESS_FS_REFER
