This has been another busy cycle for documentation, with a lot of
build-system thrashing. That work should slow down from here on out.
- The various scripts and tools for documentation were spread out in
several directories; now they are (almost) all coalesced under
tools/docs/. The holdout is the kernel-doc script, which cannot be
easily moved without some further thought.
- As the amount of Python code increases, we are accumulating modules that
are imported by multiple programs. These modules have been pulled
together under tools/lib/python/ -- at least, for documentation-related
programs. There is other Python code in the tree that might eventually
want to move toward this organization.
- The Perl kernel-doc.pl script has been removed. It is no longer used by
default, and nobody has missed it, least of all anybody who actually had
to look at it.
- The docs build was controlled by a complex mess of makefilese that few
dared to touch. Mauro has moved that logic into a new program
(tools/docs/sphinx-build-wrapper) that, with any luck at all, will be far
easier to understand and maintain.
- The get_feat.pl program, used to access information under
Documentation/features/, has been rewritten in Python, bringing an end to
the use of Perl in the docs subsystem.
- The top-level README file has been reorganized into a more
reader-friendly presentation.
- A lot of Chinese translation additions
- Typo fixes and documentation updates as usual

While simple, the drawback is that it is not possible to differentiate between memfd and tmpfs files. This adds a call to the security_inode_init_security_anon() LSM hook and wires up SELinux to provide a set of memfd specific access controls, including the ability to control the execution of memfds. As usual, the commit message has more information. - Improve the SELinux AVC lookup performance Adopt MurmurHash3 for the SELinux AVC hash function instead of the custom hash function currently used. MurmurHash3 is already used for the SELinux access vector table so the impact to the code is minimal, and performance tests have shown improvements in both hash distribution and latency. See the commit message for the performance measurments. - Introduce a Kconfig option for the SELinux AVC bucket/slot size While we have the ability to grow the number of AVC hash buckets today, the size of the buckets (slot size) is fixed at 512. This pull request makes that slot size configurable at build time through a new Kconfig knob, CONFIG_SECURITY_SELINUX_AVC_HASH_BITS. * tag 'selinux-pr-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: improve bucket distribution uniformity of avc_hash() selinux: Move avtab_hash() to a shared location for future reuse selinux: Introduce a new config to make avc cache slot size adjustable memfd,selinux: call security_inode_init_security_anon() |

Most of the patches, and diffstat, is due to splitting out the initialization code into security/lsm_init.c and cleaning up some of the mess that was there. While not strictly necessary, it does cleanup the code signficantly, and hopefully makes the upkeep a bit easier in the future. Aside from the new LSM_STARTED_ALL notification, these changes also ensure that individual LSM initcalls are only called when the LSM is enabled at boot time. There should be a minor reduction in boot times for those who build multiple LSMs into their kernels, but only enable a subset at boot.

dt-bindings: kbuild: Skip validating empty examples
Extracting empty examples results in just the empty template being generated and then validated. That's pointless and not free, so filter out the schemas without any examples from the targets. There's currently a little less than 10% of the binding schema files without examples. Removing them improves the build time by ~6%.

ipe: Update documentation for script enforcement
This patch adds explanation of script enforcement mechanism in admin guide documentation. Describes how IPE supports integrity enforcement for indirectly executed scripts through the AT_EXECVE_CHECK flag, and how this differs from kernel enforcement for compiled executables.

ipe: Add AT_EXECVE_CHECK support for script enforcement
This patch adds a new ipe_bprm_creds_for_exec() hook that integrates with the AT_EXECVE_CHECK mechanism. To enable script enforcement, interpreters need to incorporate the AT_EXECVE_CHECK flag when calling execveat() on script files before execution. When a userspace interpreter calls execveat() with the AT_EXECVE_CHECK flag, this hook triggers IPE policy evaluation on the script file. The hook only triggers IPE when bprm->is_check is true, ensuring it's being called from an AT_EXECVE_CHECK context. It then builds an evaluation context for an IPE_OP_EXEC operation and invokes IPE policy. The kernel returns the policy decision to the interpreter, which can then decide whether to proceed with script execution. This extends IPE enforcement to indirectly executed scripts, permitting trusted scripts to execute while denying untrusted ones.

arm64 FPSIMD buffer on-stack for 6.19
In v6.8, the size of task_struct on arm64 increased by 528 bytes due to the new 'kernel_fpsimd_state' field. This field was added to allow kernel-mode FPSIMD code to be preempted. Unfortunately, 528 bytes is kind of a lot for task_struct. This regression in the task_struct size was noticed and reported. Recover that space by making this state be allocated on the stack at the beginning of each kernel-mode FPSIMD section. To make it easier for all the users of kernel-mode FPSIMD to do that correctly, introduce and use a 'scoped_ksimd' abstraction. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCaSuxbxQcZWJpZ2dlcnNA a2VybmVsLm9yZwAKCRDzXCl4vpKOKysnAQCbN4Jed8IqwGUEkkjZrnMeN0pEO4RI lAhb2Obj3n/grQEAiPBmqWVjXaIPO4lSgLQxY6XoVLr+utMod4TMTYHfnAY= =0zQQ -----END PGP SIGNATURE----- Merge tag 'fpsimd-on-stack-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux Pull arm64 FPSIMD on-stack buffer updates from Eric Biggers: "This is a core arm64 change.

'at_least' array sizes for 6.19
C supports lower bounds on the sizes of array parameters, using the static keyword as follows: 'void f(int a[static 32]);'. This allows the compiler to warn about a too-small array being passed.

AES-GCM optimizations for 6.19
More optimizations and cleanups for the x86_64 AES-GCM code:
- Add a VAES+AVX2 optimized implementation of AES-GCM. This is very
helpful on CPUs that have VAES but not AVX512, such as AMD Zen 3.
- Make the VAES+AVX512 optimized implementation of AES-GCM handle
large amounts of associated data efficiently.
- Remove the "avx10_256" implementation of AES-GCM. It's superseded by
the VAES+AVX2 optimized implementation.
- Rename the "avx10_512" implementation to "avx512".
Overall, this fills in a gap where AES-GCM wasn't fully optimized on
some recent CPUs. It also drops code that won't be as useful as
initially expected due to AVX10/256 being dropped from the AVX10 spec.

Crypto library updates for 6.19
This is the main crypto library pull request for 6.19. It includes:
- Add SHA-3 support to lib/crypto/, including support for both the
hash functions and the extendable-output functions. Reimplement the
existing SHA-3 crypto_shash support on top of the library.
This is motivated mainly by the upcoming support for the ML-DSA
signature algorithm, which needs the SHAKE128 and SHAKE256
functions. But even on its own it's a useful cleanup.
This also fixes the longstanding issue where the
architecture-optimized SHA-3 code was disabled by default.
- Add BLAKE2b support to lib/crypto/, and reimplement the existing
BLAKE2b crypto_shash support on top of the library.
This is motivated mainly by btrfs, which supports BLAKE2b checksums.
With this change, all btrfs checksum algorithms now have library
APIs. btrfs is planned to start just using the library directly.
This refactor also improves consistency between the BLAKE2b code and
BLAKE2s code. And as usual, it also fixes the issue where the
architecture-optimized BLAKE2b code was disabled by default.
- Add POLYVAL support to lib/crypto/, replacing the existing POLYVAL
support in crypto_shash. Reimplement HCTR2 on top of the library.
This simplifies the code and improves HCTR2 performance. As usual,
it also makes the architecture-optimized code be enabled by default.
The generic implementation of POLYVAL is greatly improved as well.
- Clean up the BLAKE2s code.
- Add FIPS self-tests for SHA-1, SHA-2, and SHA-3.

Pull power management updates from Rafael Wysocki:
"There are quite a few interesting things here, including new hardware
support, new features, some bug fixes and documentation updates. In
addition, there are a usual bunch of minor fixes and cleanups all
over.
In the new hardware support category, there are intel_pstate and
intel_rapl driver updates to support new processors, Panther Lake,
Wildcat Lake, Noval Lake, and Diamond Rapids in the OOB mode, OPP and
bandwidth allocation support in the tegra186 cpufreq driver, and
JH7110S SOC support in dt-platdev cpufreq.
The new features are the PM QoS CPU latency limit for suspend-to-idle,
the netlink support for the energy model management, support for
terminating system suspend via a wakeup event during the sync of file
systems, configurable number of hibernation compression threads, the
runtime PM auto-cleanup macros, and the "poweroff" PM event that is
expected to be used during system shutdown.
Bugs are mostly fixed in cpuidle governors, but there are also fixes
elsewhere, like in the amd-pstate cpufreq driver.
Documentation updates include, but are not limited to, a new doc on
debugging shutdown hangs, cross-referencing fixes and cleanups in the
intel_pstate documentation, and updates of comments in the core
hibernation code.
Specifics:
- Introduce and document a QoS limit on CPU exit latency during
wakeup from suspend-to-idle (Ulf Hansson)

Pull arm64 updates from Catalin Marinas:
"These are the arm64 updates for 6.19.
The biggest part is the Arm MPAM driver under drivers/resctrl/.
There's a patch touching mm/ to handle spurious faults for huge pmd
(similar to the pte version). The corresponding arm64 part allows us
to avoid the TLB maintenance if a (huge) page is reused after a write
fault. There's EFI refactoring to allow runtime services with
preemption enabled and the rest is the usual perf/PMU updates and
several cleanups/typos.
Summary:
Core features:
- Basic Arm MPAM (Memory system resource Partitioning And Monitoring)
driver under drivers/resctrl/ which makes use of the fs/rectrl/ API
Perf and PMU:
- Avoid cycle counter on multi-threaded CPUs
- Extend CSPMU device probing and add additional filtering support

exfat: fix remount failure in different process environments
The kernel test robot reported that the exFAT remount operation failed. The reason for the failure was that the process's umask is different between mount and remount, causing fs_fmask and fs_dmask are changed. Potentially, both gid and uid may also be changed. Therefore, when initializing fs_context for remount, inherit these mount options from the options used during mount. Reported-by: kernel test robot <oliver.sang@intel.com> Closes: https://lore.kernel.org/oe-lkp/202511251637.81670f5c-lkp@intel.com Signed-off-by: Yuezhang Mo <Yuezhang.Mo@sony.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> |

exfat: fix divide-by-zero in exfat_allocate_bitmap
The variable max_ra_count can be 0 in exfat_allocate_bitmap(),
which causes a divide-by-zero error in the subsequent modulo operation
(i % max_ra_count), leading to a system crash.
When max_ra_count is 0, it means that readahead is not used. This patch
load the bitmap without readahead.
Fixes:

exfat: validate the cluster bitmap bits of directory
Syzbot created this issue by testing an image that did not have the root cluster bitmap bit marked. After accessing a file through the root directory via exfat_lookup, when creating a file again with mkdir, the root cluster bit can be allocated for direcotry, which can cause the root cluster to be zeroed out and the same entry can be allocated in the same cluster. This patch improved this issue by adding exfat_test_bitmap to validate the cluster bits of the root directory and directory. And the first cluster bit of the root directory should never be unset except when storage is corrupted. This bit is set to allow operations after mount. Reported-by: syzbot+5216036fc59c43d1ee02@syzkaller.appspotmail.com Tested-by: syzbot+5216036fc59c43d1ee02@syzkaller.appspotmail.com Reviewed-by: Sungjong Seo <sj1557.seo@samsung.com> Reviewed-by: Yuezhang Mo <Yuezhang.Mo@sony.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> |

exfat: zero out post-EOF page cache on file extension
xfstests generic/363 was failing due to unzeroed post-EOF page
cache that allowed mmap writes beyond EOF to become visible
after file extension.
For example, in following xfs_io sequence, 0x22 should not be
written to the file but would become visible after the extension:
xfs_io -f -t -c "pwrite -S 0x11 0 8" \
-c "mmap 0 4096" \
-c "mwrite -S 0x22 32 32" \
-c "munmap" \
-c "pwrite -S 0x33 512 32" \
$testfile
This violates the expected behavior where writes beyond EOF via
mmap should not persist after the file is extended. Instead, the
extended region should contain zeros.
Fix this by using truncate_pagecache() to truncate the page cache
after the current EOF when extending the file.

exfat: fix refcount leak in exfat_find
Fix refcount leaks in `exfat_find` related to `exfat_get_dentry_set`. Function `exfat_get_dentry_set` would increase the reference counter of `es->bh` on success. Therefore, `exfat_put_dentry_set` must be called after `exfat_get_dentry_set` to ensure refcount consistency. This patch relocate two checks to avoid possible leaks. Fixes: |

This makes the way memory hotplug is handled on s390 much more similar to other architectures - Remove compat support. There shouldn't be any compat user space around anymore, therefore get rid of a lot of code which also doesn't need to be tested anymore - Add stackprotector support. GCC 16 will get new compiler options, which allow to generate code required for kernel stackprotector support - Merge pai_crypto and pai_ext PMU drivers into a new driver.

It represents the first time I can think of that the upper=>kernel/lower=>user address space convention is actually recognized by the hardware on x86. It ensures that userspace can not even get the hardware to _start_ page walks for the kernel address space. This, of course, is a really nice generic side channel defense. This is really only a down payment on LASS support. There are still some details to work out in its interaction with EFI calls and vsyscall emulation. For now, LASS is disabled if either of those features is compiled in (which is almost always the case). There's also one straggler commit in here which converts an under-utilized AMD CPU feature leaf into a generic Linux-defined leaf so more feature can be packed in there.

ring-buffer: Add helper functions for allocations
The allocation of the per CPU buffer descriptor, the buffer page
descriptors and the buffer page data itself can be pretty ugly:
kzalloc_node(ALIGN(sizeof(struct buffer_page), cache_line_size()),
GFP_KERNEL, cpu_to_node(cpu));
And the data pages:
page = alloc_pages_node(cpu_to_node(cpu),
GFP_KERNEL | __GFP_RETRY_MAYFAIL | __GFP_COMP | __GFP_ZERO, order);
if (!page)
return NULL;
bpage->page = page_address(page);
rb_init_page(bpage->page);
Add helper functions to make the code easier to read.
This does make all allocations of the data page (bpage->page) allocated
with the __GFP_RETRY_MAYFAIL flag (and not just the bulk allocator). Which
is actually better, as allocating the data page for the ring buffer tracing
should try hard but not trigger the OOM killer.
