lib/crypto: riscv/poly1305: Import OpenSSL/CRYPTOGAMS implementation
This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305 implementation for riscv authored by Andy Polyakov. The file 'poly1305-riscv.pl' is taken straight from https://github.com/dot-asm/cryptogams commit 5e3fba73576244708a752fa61a8e93e587f271bb. This patch was tested on SpacemiT X60, with 2~2.5x improvement over generic implementation.

lib/crypto: poly1305: Consolidate into single module
Consolidate the Poly1305 code into a single module, similar to various other algorithms (SHA-1, SHA-256, SHA-512, etc.): - Each arch now provides a header file lib/crypto/$(SRCARCH)/poly1305.h, replacing lib/crypto/$(SRCARCH)/poly1305*.c. The header defines poly1305_block_init(), poly1305_blocks(), poly1305_emit(), and optionally poly1305_mod_init_arch(). It is included by lib/crypto/poly1305.c, and thus the code gets built into the single libpoly1305 module, with improved inlining in some cases. - Whether arch-optimized Poly1305 is buildable is now controlled centrally by lib/crypto/Kconfig instead of by lib/crypto/$(SRCARCH)/Kconfig. The conditions for enabling it remain the same as before, and it remains enabled by default. (The PPC64 one remains unconditionally disabled due to 'depends on BROKEN'.) - Any additional arch-specific translation units for the optimized Poly1305 code, such as assembly files, are now compiled by lib/crypto/Makefile instead of lib/crypto/$(SRCARCH)/Makefile. A special consideration is needed because the Adiantum code uses the poly1305_core_*() functions directly. For now, just carry forward that approach. This means retaining the CRYPTO_LIB_POLY1305_GENERIC kconfig symbol, and keeping the poly1305_core_*() functions in separate translation units. So it's not quite as streamlined I've done with the other hash functions, but we still get a single libpoly1305 module. Note: to see the diff from the arm, arm64, and x86 .c files to the new .h files, view this commit with 'git show -M10'.

kunit: Enable direct registration of parameter arrays to a KUnit test
KUnit parameterized tests currently support two primary methods f
or getting parameters:
1. Defining custom logic within a generate_params() function.
2. Using the KUNIT_ARRAY_PARAM() and KUNIT_ARRAY_PARAM_DESC()
macros with a pre-defined static array and passing
the created *_gen_params() to KUNIT_CASE_PARAM().
These methods present limitations when dealing with dynamically
generated parameter arrays, or in scenarios where populating parameters
sequentially via generate_params() is inefficient or overly complex.
This patch addresses these limitations by adding a new `params_array`
field to `struct kunit`, of the type `kunit_params`. The
`struct kunit_params` is designed to store the parameter array itself,
along with essential metadata including the parameter count, parameter
size, and a get_description() function for providing custom descriptions
for individual parameters.
The `params_array` field can be populated by calling the new
kunit_register_params_array() macro from within a param_init() function.
This will register the array as part of the parameterized test context.
The user will then need to pass kunit_array_gen_params() to the
KUNIT_CASE_PARAM_WITH_INIT() macro as the generator function, if not
providing their own. kunit_array_gen_params() is a KUnit helper that will
use the registered array to generate parameters.
The arrays passed to KUNIT_ARRAY_PARAM(,DESC) will also be registered to
the parameterized test context for consistency as well as for higher
availability of the parameter count that will be used for outputting a KTAP
test plan for a parameterized test.
This modification provides greater flexibility to the KUnit framework,
allowing testers to easily register and utilize both dynamic and static
parameter arrays.

kunit: Pass parameterized test context to generate_params()
To enable more complex parameterized testing scenarios, the generate_params() function needs additional context beyond just the previously generated parameter. This patch modifies the generate_params() function signature to include an extra `struct kunit *test` argument, giving test users access to the parameterized test context when generating parameters. The `struct kunit *test` argument was added as the first parameter to the function signature as it aligns with the convention of other KUnit functions that accept `struct kunit *test` first. This also mirrors the "this" or "self" reference found in object-oriented programming languages. This patch also modifies xe_pci_live_device_gen_param() in xe_pci.c and nthreads_gen_params() in kcsan_test.c to reflect this signature change.

kunit: Add parent kunit for parameterized test context
Currently, KUnit parameterized tests lack a mechanism to share resources across parameter runs because the same `struct kunit` instance is cleaned up and reused for each run. This patch introduces parameterized test context, enabling test users to share resources between parameter runs. It also allows setting up resources that need to be available for all parameter runs only once, which is helpful in cases where setup is expensive. To establish a parameterized test context, this patch adds a parent pointer field to `struct kunit`. This allows resources added to the parent `struct kunit` to be shared and accessible across all parameter runs. In kunit_run_tests(), the default `struct kunit` created is now designated to act as the parameterized test context whenever a test is parameterized. Subsequently, a new `struct kunit` is made for each parameter run, and its parent pointer is set to the `struct kunit` that holds the parameterized test context.

lib/crypto: sparc/md5: Migrate optimized code into library

lib/crypto: md5: Add MD5 and HMAC-MD5 library functions
Add library functions for MD5, including HMAC support. The MD5 implementation is derived from crypto/md5.c. This closely mirrors the corresponding SHA-1 and SHA-2 changes. Like SHA-1 and SHA-2, support for architecture-optimized MD5 implementations is included. I originally proposed dropping those, but unfortunately there is an AF_ALG user of the PowerPC MD5 code (https://lore.kernel.org/r/c4191597-341d-4fd7-bc3d-13daf7666c41@csgroup.eu/), and dropping that code would be viewed as a performance regression. We don't add new software algorithm implementations purely for AF_ALG, as escalating to kernel mode merely to do calculations that could be done in userspace is inefficient and is completely the wrong design. But since this one already existed, it gets grandfathered in for now. An objection was also raised to dropping the SPARC64 MD5 code because it utilizes the CPU's direct support for MD5, although it remains unclear that anyone is using that. Regardless, we'll keep these around for now. Note that while MD5 is a legacy algorithm that is vulnerable to practical collision attacks, it still has various in-kernel users that implement legacy protocols. Switching to a simple library API, which is the way the code should have been organized originally, will greatly simplify their code. For example: MD5: drivers/md/dm-crypt.c (for lmk IV generation) fs/nfsd/nfs4recover.c fs/ecryptfs/ fs/smb/client/ net/{ipv4,ipv6}/ (for TCP-MD5 signatures) HMAC-MD5: fs/smb/client/ fs/smb/server/ (Also net/sctp/ if it continues using HMAC-MD5 for cookie generation. However, that use case has the flexibility to upgrade to a more modern algorithm, which I'll be proposing instead.) As usual, the "md5" and "hmac(md5)" crypto_shash algorithms will also be reimplemented on top of these library functions. For "hmac(md5)" this will provide a faster, more streamlined implementation.

ref_tracker: use %p instead of %px in debugfs dentry name
As Kees points out, this is a kernel address leak, and debugging is
not a sufficiently good reason to expose the real kernel address.

lib/crc: Use underlying functions instead of crypto_simd_usable()
Since crc_kunit now tests the fallback code paths without using crypto_simd_disabled_for_test, make the CRC code just use the underlying may_use_simd() and irq_fpu_usable() functions directly instead of crypto_simd_usable(). This eliminates an unnecessary layer. Take the opportunity to add likely() and unlikely() annotations as well.

lib/crc: crc_kunit: Test CRC computation in interrupt contexts
Test that if CRCs are computed in task, softirq, and hardirq context concurrently, then all results are as expected. Implement this using kunit_run_irq_test() which is also used by the lib/crypto/ tests. As with the corresponding lib/crypto/ tests, the purpose of this is to test fallback code paths and to exercise edge cases in the architecture's support for in-kernel FPU/SIMD/vector. Remove the code from crc_test() that sometimes disabled interrupts, as that was just an incomplete attempt to achieve similar test coverage.

lib/sbitmap: convert shallow_depth from one word to the whole sbitmap
Currently elevators will record internal 'async_depth' to throttle asynchronous requests, and they both calculate shallow_dpeth based on sb->shift, with the respect that sb->shift is the available tags in one word. However, sb->shift is not the availbale tags in the last word, see __map_depth: if (index == sb->map_nr - 1) return sb->depth - (index << sb->shift); For consequence, if the last word is used, more tags can be get than expected, for example, assume nr_requests=256 and there are four words, in the worst case if user set nr_requests=32, then the first word is the last word, and still use bits per word, which is 64, to calculate async_depth is wrong. One the ohter hand, due to cgroup qos, bfq can allow only one request to be allocated, and set shallow_dpeth=1 will still allow the number of words request to be allocated. Fix this problems by using shallow_depth to the whole sbitmap instead of per word, also change kyber, mq-deadline and bfq to follow this, a new helper __map_depth_with_shallow() is introduced to calculate available bits in each word.

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.

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.

kho: add test for kexec handover
Testing kexec handover requires a kernel driver that will generate some data and preserve it with KHO on the first boot and then restore that data and verify it was preserved properly after kexec. To facilitate such test, along with the kernel driver responsible for data generation, preservation and restoration add a script that runs a kernel in a VM with a minimal /init. The /init enables KHO, loads a kernel image for kexec and runs kexec reboot. After the boot of the kexeced kernel, the driver verifies that the data was properly preserved.

Summary of significant series in this pull request:
- The 4 patch series "mm: ksm: prevent KSM from breaking merging of new
VMAs" from Lorenzo Stoakes addresses an issue with KSM's
PR_SET_MEMORY_MERGE mode: newly mapped VMAs were not eligible for
merging with existing adjacent VMAs.

test_bits: add tests for __GENMASK() and __GENMASK_ULL()
The definitions of GENMASK() and GENMASK_ULL() do not depend any more
on __GENMASK() and __GENMASK_ULL(). Duplicate the existing unit tests
so that __GENMASK{,ULL}() are still covered.
Because __GENMASK() and __GENMASK_ULL() do use GENMASK_INPUT_CHECK(),
drop the TEST_GENMASK_FAILURES negative tests.
It would be good to have a small assembly test case for GENMASK*() in
case somebody decides to unify both in the future. However, I lack
expertise in assembly to do so. Instead add a FIXME message to
highlight the absence of the asm unit test.

kunit: test: Drop CONFIG_MODULE ifdeffery
The function stubs exposed by module.h allow the code to compile properly without the ifdeffery. The generated object code stays the same, as the compiler can optimize away all the dead code.

Networking changes for 6.17.
Core & protocols
----------------
- Wrap datapath globals into net_aligned_data, to avoid false sharing.
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
- Add SO_INQ and SCM_INQ support to AF_UNIX.
- Add SIOCINQ support to AF_VSOCK.
- Add TCP_MAXSEG sockopt to MPTCP.
- Add IPv6 force_forwarding sysctl to enable forwarding per interface.
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB.
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users.
- Convert TCP send queue handling from tasklet to BH workque.
- Improve BPF iteration over TCP sockets to see each socket exactly once.
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel NAPI
thread when threaded NAPI gets disabled. Previously thread would stick
around until ifdown due to tricky synchronization.
- Allow multicast routing to take effect on locally-generated packets.
- Add output interface argument for End.X in segment routing.
- MCTP: add support for gateway routing, improve bind() handling.
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed.
- Support NUD_PERMANENT for proxy neighbor entries.
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
- Add sequence numbers to netconsole messages. Unregister netconsole's
console when all net targets are removed. Code refactoring.
Add a number of selftests.
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup.
- Support inspecting ref_tracker state via DebugFS.
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links.
- Allow providing upcall pid for the 'execute' command in openvswitch.
- Remove DCCP support from Netfilter's conntrack.
- Disallow multiple packet duplications in the queuing layer.
- Prevent use of deprecated iptables code on PREEMPT_RT.
Driver API
----------
- Support RSS and hashing configuration over ethtool Netlink.
- Add dedicated ethtool callbacks for getting and setting hashing fields.

Merge tag 'net-next-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Wrap datapath globals into net_aligned_data, to avoid false sharing
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container)
- Add SO_INQ and SCM_INQ support to AF_UNIX
- Add SIOCINQ support to AF_VSOCK
- Add TCP_MAXSEG sockopt to MPTCP
- Add IPv6 force_forwarding sysctl to enable forwarding per interface
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users
- Convert TCP send queue handling from tasklet to BH workque
- Improve BPF iteration over TCP sockets to see each socket exactly
once
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel
NAPI thread when threaded NAPI gets disabled. Previously thread
would stick around until ifdown due to tricky synchronization
- Allow multicast routing to take effect on locally-generated packets
- Add output interface argument for End.X in segment routing
- MCTP: add support for gateway routing, improve bind() handling
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed
- Support NUD_PERMANENT for proxy neighbor entries
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM
- Add sequence numbers to netconsole messages. Unregister
netconsole's console when all net targets are removed. Code
refactoring. Add a number of selftests
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup
- Support inspecting ref_tracker state via DebugFS
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links
- Allow providing upcall pid for the 'execute' command in openvswitch
- Remove DCCP support from Netfilter's conntrack
- Disallow multiple packet duplications in the queuing layer
- Prevent use of deprecated iptables code on PREEMPT_RT
Driver API:
- Support RSS and hashing configuration over ethtool Netlink
- Add dedicated ethtool callbacks for getting and setting hashing
fields

Summary
* Move sysctls out of the kern_table array
This is the final move of ctl_tables into their respective subsystems. Only 5
(out of the original 50) will remain in kernel/sysctl.c file; these handle
either sysctl or common arch variables.
By decentralizing sysctl registrations, subsystem maintainers regain control
over their sysctl interfaces, improving maintainability and reducing the
likelihood of merge conflicts.
* docs: Remove false positives from check-sysctl-docs
Stopped falsely identifying sysctls as undocumented or unimplemented in the
check-sysctl-docs script. This script can now be used to automatically
identify if documentation is missing.
* Testing
All these have been in linux-next since rc3, giving them a solid 3 to 4 weeks
worth of testing. Additionally, sysctl selftests and kunit were also run
locally on my x86_64

s390 updates for 6.17 merge window
- Standardize on the __ASSEMBLER__ macro that is provided by GCC and Clang compilers and replace __ASSEMBLY__ with __ASSEMBLER__ in both uapi and non-uapi headers - Explicitly include <linux/export.h> in architecture and driver files which contain an EXPORT_SYMBOL() and remove the include from the files which do not contain the EXPORT_SYMBOL() - Use the full title of "z/Architecture Principles of Operation" manual and the name of a section where facility bits are listed - Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid unnecessary slowing down of the build and confusing external kABI tools that process symtypes data - Print additional unrecoverable machine check information to make the root cause analysis easier - Move cmpxchg_user_key() handling to uaccess library code, since the generated code is large anyway and there is no benefit if it is inlined - Fix a problem when cmpxchg_user_key() is executing a code with a non-default key: if a system is IPL-ed with "LOAD NORMAL", and the previous system used storage keys where the fetch-protection bit was set for some pages, and the cmpxchg_user_key() is located within such page, a protection exception happens - Either the external call or emergency signal order is used to send an IPI to a remote CPU. Use the external order only, since it is at least as good and sometimes even better, than the emergency signal - In case of an early crash the early program check handler prints more or less random value of the last breaking event address, since it is not initialized properly. Copy the last breaking event address from the lowcore to pt_regs to address this - During STP synchronization check udelay() can not be used, since the first CPU modifies tod_clock_base and get_tod_clock_monotonic() might return a non-monotonic time. Instead, busy-loop on other CPUs, while the the first CPU actually handles the synchronization operation - When debugging the early kernel boot using QEMU with the -S flag and GDB attached, skip the decompressor and start directly in kernel - Rename PAI Crypto event 4210 according to z16 and z17 "z/Architecture Principles of Operation" manual - Remove the in-kernel time steering support in favour of the new s390 PTP driver, which allows the kernel clock steered more precisely - Remove a possible false-positive warning in pte_free_defer(), which could be triggered in a valid case KVM guest process is initializing -----BEGIN PGP SIGNATURE----- iI0EABYKADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCaIJQThccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8FI2APwPnlrj6ZVXzNA6dw0fSUt697rS NlaHEORXL8KcfoQh8QD/WwHUe1VNtDG1R5bBn0guR+UytVgR9Tt7LxyKfIgT3ws= =tdMb -----END PGP SIGNATURE----- Merge tag 's390-6.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Standardize on the __ASSEMBLER__ macro that is provided by GCC and Clang compilers and replace __ASSEMBLY__ with __ASSEMBLER__ in both uapi and non-uapi headers - Explicitly include <linux/export.h> in architecture and driver files which contain an EXPORT_SYMBOL() and remove the include from the files which do not contain the EXPORT_SYMBOL() - Use the full title of "z/Architecture Principles of Operation" manual and the name of a section where facility bits are listed - Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid unnecessary slowing down of the build and confusing external kABI tools that process symtypes data - Print additional unrecoverable machine check information to make the root cause analysis easier - Move cmpxchg_user_key() handling to uaccess library code, since the generated code is large anyway and there is no benefit if it is inlined - Fix a problem when cmpxchg_user_key() is executing a code with a non-default key: if a system is IPL-ed with "LOAD NORMAL", and the previous system used storage keys where the fetch-protection bit was set for some pages, and the cmpxchg_user_key() is located within such page, a protection exception happens - Either the external call or emergency signal order is used to send an IPI to a remote CPU.

Scheduler updates for v6.17:
Core scheduler changes:
- Better tracking of maximum lag of tasks in presence of different
slices duration, for better handling of lag in the fair
scheduler. (Vincent Guittot)
- Clean up and standardize #if/#else/#endif markers throughout
the entire scheduler code base (Ingo Molnar)
- Make SMP unconditional: build the SMP scheduler's
data structures and logic on UP kernel too, even though
they are not used, to simplify the scheduler and remove
around 200 #ifdef/[#else]/#endif blocks from the
scheduler. (Ingo Molnar)
- Reorganize cgroup bandwidth control interface handling
for better interfacing with sched_ext (Tejun Heo)
Balancing:
- Bump sd->max_newidle_lb_cost when newidle balance fails (Chris Mason)
- Remove sched_domain_topology_level::flags to simplify the code (Prateek Nayak)
- Simplify and clean up build_sched_topology() (Li Chen)
- Optimize build_sched_topology() on large machines (Li Chen)
Real-time scheduling:
- Add initial version of proxy execution: a mechanism for mutex-owning
tasks to inherit the scheduling context of higher priority waiters.
Currently limited to a single runqueue and conditional on CONFIG_EXPERT,
and other limitations. (John Stultz, Peter Zijlstra, Valentin Schneider)
- Deadline scheduler (Juri Lelli):
- Fix dl_servers initialization order (Juri Lelli)
- Fix DL scheduler's root domain reinitialization logic (Juri Lelli)
- Fix accounting bugs after global limits change (Juri Lelli)
- Fix scalability regression by implementing less agressive dl_server handling
(Peter Zijlstra)
PSI:
- Improve scalability by optimizing psi_group_change() cpu_clock() usage
(Peter Zijlstra)
Rust changes:
- Make Task, CondVar and PollCondVar methods inline to avoid unnecessary
function calls (Kunwu Chan, Panagiotis Foliadis)
- Add might_sleep() support for Rust code: Rust's "#[track_caller]"
mechanism is used so that Rust's might_sleep() doesn't need to be
defined as a macro (Fujita Tomonori)
- Introduce file_from_location() (Boqun Feng)
Debugging & instrumentation:
- Make clangd usable with scheduler source code files again (Peter Zijlstra)
- tools: Add root_domains_dump.py which dumps root domains info (Juri Lelli)
- tools: Add dl_bw_dump.py for printing bandwidth accounting info (Juri Lelli)
Misc cleanups & fixes:
- Remove play_idle() (Feng Lee)
- Fix check_preemption_disabled() (Sebastian Andrzej Siewior)
- Do not call __put_task_struct() on RT if pi_blocked_on is set
(Luis Claudio R. Goncalves)
- Correct the comment in place_entity() (wang wei)

Updates for the timekeeping and VDSO code:
- Introduce support for auxiliary timekeepers
PTP clocks can be disconnected from the universal CLOCK_TAI reality
for various reasons including regularatory requirements for
functional safety redundancy.
The kernel so far only supports a single notion of time, which means
that all clocks are correlated in frequency and only differ by
offset to each other.
Access to non-correlated PTP clocks has been available so far only
through the file descriptor based "POSIX clock IDs", which are
subject to locking and have to go all the way out to the hardware.
The access is not only horribly slow, as it has to go all the way out
to the NIC/PTP hardware, but that also prevents the kernel to read
the time of such clocks e.g. from the network stack, where it is
required for TSN networking both on the transmit and receive side
unless the hardware provides offloading.
The auxiliary clocks provide a mechanism to support arbitrary clocks
which are not correlated to the system clock. This is not restricted
to the PTP use case on purpose as there is no kernel side association
of these clocks to a particular PTP device because that's a pure user
space configuration decision. Having them independent allows to
utilize them for other purposes and also enables them to be tested
without hardware dependencies.
To avoid pointless overhead these clocks have to be enabled
individualy via a new sysfs interface to reduce the overhead to a
single compare in the hotpath if they are enabled at the Kconfig
level at all.
These clocks utilize the existing timekeeping/NTP infrastructures,
which has been made possible over the recent releases by incrementaly
converting these infrastructures over from a single static instance
to a multi-instance pointer based implementation without any
performance regression reported.
The auxiliary clocks provide the same "emulation" of a "correct"
clock as the existing CLOCK_* variants do with an independent
instance of data and provide the same steering mechanism through the
existing sys_clock_adjtime() interface, which has been confirmed to
work by the chronyd(8) maintainer.
That allows to provide lockless kernel internal and VDSO support so
that applications and kernel internal functionalities can access
these clocks without restrictions and at the same performance as the
existing system clocks.
- Avoid double notifications in the adjtimex() syscall. Not a big issue,
but a trivial to avoid latency source.

Crypto library tests for 6.17
Add KUnit test suites for the Poly1305, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 library functions. These are the first KUnit tests for lib/crypto/. So in addition to being useful tests for these specific algorithms, they also establish some conventions for lib/crypto/ testing going forwards. The new tests are fairly comprehensive: more comprehensive than the generic crypto infrastructure's tests. They use a variety of techniques to check for the types of implementation bugs that tend to occur in the real world, rather than just naively checking some test vectors. (Interestingly, poly1305_kunit found a bug in QEMU.) The core test logic is shared by all six algorithms, rather than being duplicated for each algorithm. Each algorithm's test suite also optionally includes a benchmark. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCaIZ+WhQcZWJpZ2dlcnNA a2VybmVsLm9yZwAKCRDzXCl4vpKOK+C4AQCOi7iOlFLouUfu9klrovp3i/iSMhyQ gUEHPGSelBy4wQD+NnrLGIdpCcaDAzyWpT4TxG6esN2/97ewh4VUa2MDuQQ= =rS0F -----END PGP SIGNATURE----- Merge tag 'libcrypto-tests-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux Pull crypto library test updates from Eric Biggers: "Add KUnit test suites for the Poly1305, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 library functions.

Crypto library updates for 6.17
This is the main crypto library pull request for 6.17. The main focus
this cycle is on reorganizing the SHA-1 and SHA-2 code, providing
high-quality library APIs for SHA-1 and SHA-2 including HMAC support,
and establishing conventions for lib/crypto/ going forward:
- Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares
most of the SHA-512 code) into lib/crypto/. This includes both the
generic and architecture-optimized code. Greatly simplify how the
architecture-optimized code is integrated. Add an easy-to-use
library API for each SHA variant, including HMAC support. Finally,
reimplement the crypto_shash support on top of the library API.
- Apply the same reorganization to the SHA-256 code (and also SHA-224
which shares most of the SHA-256 code). This is a somewhat smaller
change, due to my earlier work on SHA-256. But this brings in all
the same additional improvements that I made for SHA-1 and SHA-512.
There are also some smaller changes:
- Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code
from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For
these algorithms it's just a move, not a full reorganization yet.
- Fix the MIPS chacha-core.S to build with the clang assembler.
- Fix the Poly1305 functions to work in all contexts.
- Fix a performance regression in the x86_64 Poly1305 code.
- Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.
Note that since the new organization of the SHA code is much simpler,
the diffstat of this pull request is negative, despite the addition of
new fully-documented library APIs for multiple SHA and HMAC-SHA
variants. These APIs will allow further simplifications across the
kernel as users start using them instead of the old-school crypto API.
(I've already written a lot of such conversion patches, removing over
1000 more lines of code. But most of those will target 6.18 or later.)

CRC updates for 6.17
Updates for the kernel's CRC (cyclic redundancy check) code:
- Reorganize the architecture-optimized CRC code. It now lives in
lib/crc/$(SRCARCH)/ rather than arch/$(SRCARCH)/lib/, and it is no
longer artificially split into separate generic and arch modules.
This allows better inlining and dead code elimination. The generic
CRC code is also no longer exported, simplifying the API. (This
mirrors the similar changes to SHA-1 and SHA-2 in lib/crypto/,
which can be found in the "Crypto library updates" pull request.)
- Improve crc32c() performance on newer x86_64 CPUs on long messages

- Reorganize the architecture-optimized CRC code
It now lives in lib/crc/$(SRCARCH)/ rather than arch/$(SRCARCH)/lib/,
and it is no longer artificially split into separate generic and arch
modules. This allows better inlining and dead code elimination
The generic CRC code is also no longer exported, simplifying the API.
(This mirrors the similar changes to SHA-1 and SHA-2 in lib/crypto/,
which can be found in the "Crypto library updates" pull request)

stackleak: Rename STACKLEAK to KSTACK_ERASE
In preparation for adding Clang sanitizer coverage stack depth tracking that can support stack depth callbacks: - Add the new top-level CONFIG_KSTACK_ERASE option which will be implemented either with the stackleak GCC plugin, or with the Clang stack depth callback support. - Rename CONFIG_GCC_PLUGIN_STACKLEAK as needed to CONFIG_KSTACK_ERASE, but keep it for anything specific to the GCC plugin itself. - Rename all exposed "STACKLEAK" names and files to "KSTACK_ERASE" (named for what it does rather than what it protects against), but leave as many of the internals alone as possible to avoid even more churn. While here, also split "prev_lowest_stack" into CONFIG_KSTACK_ERASE_METRICS, since that's the only place it is referenced from.

The assembly code that does all 80 rounds of SHA-1 is highly repetitive. Replace it with 20 expansions of a macro that does 4 rounds, using the macro arguments and .if directives to handle the slight variations between rounds. This reduces the length of sha1-ni-asm.S by 129 lines while still producing the exact same object file. This mirrors sha256-ni-asm.S which uses this same strategy.

lib/crypto: x86/sha1-ni: Minor optimizations and cleanup
- Store the previous state in %xmm8-%xmm9 instead of spilling it to the stack. There are plenty of unused XMM registers here, so there is no reason to spill to the stack. (While 32-bit code is limited to %xmm0-%xmm7, this is 64-bit code, so it's free to use %xmm8-%xmm15.) - Remove the unnecessary check for nblocks == 0. sha1_ni_transform() is always passed a positive nblocks. - To get an XMM register with 'e' in the high dword and the rest zeroes, just zeroize the register using pxor, then load 'e'. Previously the code loaded 'e', then zeroized the lower dwords by AND-ing with a constant, which was slightly less efficient. - Instead of computing &DATA_PTR[NBLOCKS << 6] and stopping when DATA_PTR reaches that value, instead just decrement NBLOCKS on each iteration and stop when it reaches 0. This is fewer instructions. - Rename DIGEST_PTR to STATE_PTR. It points to the SHA-1 internal state, not a SHA-1 digest value. This commit shrinks the code size of sha1_ni_transform() from 624 bytes to 589 bytes and also shrinks rodata by 16 bytes.

lib/crc: x86/crc32c: Enable VPCLMULQDQ optimization where beneficial
Improve crc32c() performance on lengths >= 512 bytes by using
crc32_lsb_vpclmul_avx512() instead of crc32c_x86_3way(), when the CPU
supports VPCLMULQDQ and has a "good" implementation of AVX-512. For now
that means AMD Zen 4 and later, and Intel Sapphire Rapids and later.
Pass crc32_lsb_vpclmul_avx512() the table of constants needed to make it
use the CRC-32C polynomial.
Rationale: VPCLMULQDQ performance has improved on newer CPUs, making
crc32_lsb_vpclmul_avx512() faster than crc32c_x86_3way(), even though
crc32_lsb_vpclmul_avx512() is designed for generic 32-bit CRCs and does
not utilize x86_64's dedicated CRC-32C instructions.
Performance results for len=4096 using crc_kunit:
CPU Before (MB/s) After (MB/s)
====================== ============= ============
AMD Zen 4 (Genoa) 19868 28618
AMD Zen 5 (Ryzen AI 9 365) 24080 46940
AMD Zen 5 (Turin) 29566 58468
Intel Sapphire Rapids 22340 73794
Intel Emerald Rapids 24696 78666
Performance results for len=512 using crc_kunit:
CPU Before (MB/s) After (MB/s)
====================== ============= ============
AMD Zen 4 (Genoa) 7251 7758
AMD Zen 5 (Ryzen AI 9 365) 17481 19135
AMD Zen 5 (Turin) 21332 25424
Intel Sapphire Rapids 18886 29312
Intel Emerald Rapids 19675 29045
That being said, in the above benchmarks the ZMM registers are "warm",
so they don't quite tell the whole story. While significantly improved
from older Intel CPUs, Intel still has ~2000 ns of ZMM warm-up time
where 512-bit instructions execute 4 times more slowly than they
normally do. In contrast, AMD does better and has virtually zero ZMM
warm-up time (at most ~60 ns). Thus, while this change is always
beneficial on AMD, strictly speaking there are cases in which it is not
beneficial on Intel, e.g. a small number of 512-byte messages with
"cold" ZMM registers. But typically, it is beneficial even on Intel.
Note that on AMD Zen 3--5, crc32c() performance could be further
improved with implementations that interleave crc32q and VPCLMULQDQ
instructions. Unfortunately, it appears that a different such
implementation would be optimal on *each* of these microarchitectures.
Such improvements are left for future work. This commit just improves
the way that we choose the implementations we already have.

lib/crc: x86: Reorganize crc-pclmul static_call initialization
Reorganize the crc-pclmul static_call initialization to place more of the logic in the *_mod_init_arch() functions instead of in the INIT_CRC_PCLMUL macro. This provides the flexibility to do more than a single static_call update for each CPU feature check. Right away, optimize crc64_mod_init_arch() to check the CPU features just once instead of twice, doing both the crc64_msb and crc64_lsb static_call updates together. A later commit will also use this to initialize an additional static_key when crc32_lsb_vpclmul_avx512() is enabled.

lib/math/gcd: use static key to select implementation at runtime
Patch series "Optimize GCD performance on RISC-V by selecting implementation at runtime", v3. The current implementation of gcd() selects between the binary GCD and the odd-even GCD algorithm at compile time, depending on whether CONFIG_CPU_NO_EFFICIENT_FFS is set. On platforms like RISC-V, however, this compile-time decision can be misleading: even when the compiler emits ctz instructions based on the assumption that they are efficient (as is the case when CONFIG_RISCV_ISA_ZBB is enabled), the actual hardware may lack support for the Zbb extension. In such cases, ffs() falls back to a software implementation at runtime, making the binary GCD algorithm significantly slower than the odd-even variant. To address this, we introduce a static key to allow runtime selection between the binary and odd-even GCD implementations. On RISC-V, the kernel now checks for Zbb support during boot. If Zbb is unavailable, the static key is disabled so that gcd() consistently uses the more efficient odd-even algorithm in that scenario. Additionally, to further reduce code size, we select CONFIG_CPU_NO_EFFICIENT_FFS automatically when CONFIG_RISCV_ISA_ZBB is not enabled, avoiding compilation of the unused binary GCD implementation entirely on systems where it would never be executed. This series ensures that the most efficient GCD algorithm is used in practice and avoids compiling unnecessary code based on hardware capabilities and kernel configuration. This patch (of 3): On platforms like RISC-V, the compiler may generate hardware FFS instructions even if the underlying CPU does not actually support them. Currently, the GCD implementation is chosen at compile time based on CONFIG_CPU_NO_EFFICIENT_FFS, which can result in suboptimal behavior on such systems. Introduce a static key, efficient_ffs_key, to enable runtime selection between the binary GCD (using ffs) and the odd-even GCD implementation. This allows the kernel to default to the faster binary GCD when FFS is efficient, while retaining the ability to fall back when needed.

kunit: test: Export kunit_attach_mm()
Tests can allocate from virtual memory using kunit_vm_mmap(), which transparently creates and attaches an mm_struct to the test runner if one is not already attached. This is suitable for most cases, except for when the code under test must access a task's mm before performing an mmap. Expose kunit_attach_mm() as part of the interface for those cases. This does not change the existing behavior.

kunit/fortify: Add back "volatile" for sizeof() constants
It seems the Clang can see through OPTIMIZER_HIDE_VAR when the constant
is coming from sizeof. Adding "volatile" back to these variables solves
this false positive without reintroducing the issues that originally led
to switching to OPTIMIZER_HIDE_VAR in the first place[1].

lib/crypto: sha2: Add hmac_sha*_init_usingrawkey()
While the HMAC library functions support both incremental and one-shot computation and both prepared and raw keys, the combination of raw key + incremental was missing. It turns out that several potential users of the HMAC library functions (tpm2-sessions.c, smb2transport.c, trusted_tpm1.c) want exactly that. Therefore, add the missing functions hmac_sha*_init_usingrawkey(). Implement them in an optimized way that directly initializes the HMAC context without a separate key preparation step. Reimplement the one-shot raw key functions hmac_sha*_usingrawkey() on top of the new functions, which makes them a bit more efficient.

Since most of the work in this function is duplicated for the two, split it up into separate functions that each use one of them. The combined stack usage is still the same here, but there is no warning any more, and the code is still safe because of the known call chain.

maple_tree: fix status setup on restore to active
During the initial call with a maple state, an error status may be set
before a valid node is populated into the maple state node. Subsequent
calls with the maple state may restore the state into an active state with
no node set. This was masked by the mas_walk() always resetting the
status to ma_start and result in an extra walk in this rare scenario.
Don't restore the state to active unless there is a value in the structs
node. This also allows mas_walk() to be fixed to use the active state
without exposing an issue.
User visible results are marginal performance improvements when an active
state can be restored and used instead of rewalking the tree.
Stable is not Cc'ed because the existing code is stable and the
performance gains are not worth the risk.

lib/test_vmalloc.c: restrict default test mask to avoid test warnings
When the vmalloc test is built into the kernel, it runs automatically during the boot. The current-default "run_test_mask" includes all test cases, including those which are designed to fail and which trigger kernel warnings. These kernel splats can be misinterpreted as actual kernel bugs, leading to false alarms and unnecessary reports. To address this, limit the default test mask to only the first few tests which are expected to pass cleanly. These tests are safe and should not generate any warnings unless there is a real bug. Users who wish to explicitly run specific test cases have to pass the run_test_mask as a boot parameter or at module load time.

lib/test_vmalloc.c: use late_initcall() if built-in for init ordering
When the vmalloc test code is compiled as a built-in, use late_initcall() instead of module_init() to defer a vmalloc test execution until most subsystems are up and running. It avoids interfering with components that may not yet be initialized at module_init() time. For example, there was a recent report of memory profiling infrastructure not being ready early enough leading to kernel crash. By using late_initcall() in the built-in case, we ensure the tests are run at a safer point during a boot sequence.

mm/percpu: conditionally define _shared_alloc_tag via CONFIG_ARCH_MODULE_NEEDS_WEAK_PER_CPU
Recently discovered this entry while checking kallsyms on ARM64: ffff800083e509c0 D _shared_alloc_tag If ARCH_NEEDS_WEAK_PER_CPU is not defined(it is only defined for s390 and alpha architectures), there's no need to statically define the percpu variable _shared_alloc_tag. Therefore, we need to implement isolation for this purpose. When building the core kernel code for s390 or alpha architectures, ARCH_NEEDS_WEAK_PER_CPU remains undefined (as it is gated by #if defined(MODULE)). However, when building modules for these architectures, the macro is explicitly defined. Therefore, we remove all instances of ARCH_NEEDS_WEAK_PER_CPU from the code and introduced CONFIG_ARCH_MODULE_NEEDS_WEAK_PER_CPU to replace the relevant logic. We can now conditionally define the perpcu variable _shared_alloc_tag based on CONFIG_ARCH_MODULE_NEEDS_WEAK_PER_CPU. This allows architectures (such as s390/alpha) that require weak definitions for percpu variables in modules to include the definition, while others can omit it via compile-time exclusion.

alloc_tag: keep codetag iterator active between read()
When reading /proc/allocinfo, for each read syscall, seq_file would invoke
start/stop callbacks. In start callback, a memory is alloced to store
iterator and the iterator would start from beginning to walk linearly to
current read position.
seq_file read() takes at most 4096 bytes, even if read with a larger user
space buffer, meaning read out all of /proc/allocinfo, tens of read
syscalls are needed. For example, a 306036 bytes allocinfo files need 76
reads:
$ sudo cat /proc/allocinfo | wc
3964 16678 306036
$ sudo strace -T -e read cat /proc/allocinfo
...
read(3, " 4096 1 arch/x86/k"..., 131072) = 4063 <0.000062>
...
read(3, " 0 0 sound/core"..., 131072) = 4021 <0.000150>
...
For those n=3964 lines, each read takes about m=3964/76=52 lines,
since iterator restart from beginning for each read(),
it would move forward
m steps on 1st read
2*m steps on 2nd read
3*m steps on 3rd read
...
n steps on last read
As read() along, those linear seek steps make read() calls slower and
slower. Adding those up, codetag iterator moves about O(n*n/m) steps,
making data structure traversal take significant part of the whole
reading. Profiling when stress reading /proc/allocinfo confirms it:
vfs_read(99.959% 1677299/1677995)
proc_reg_read_iter(99.856% 1674881/1677299)
seq_read_iter(99.959% 1674191/1674881)
allocinfo_start(75.664% 1266755/1674191)
codetag_next_ct(79.217% 1003487/1266755) <---
srso_return_thunk(1.264% 16011/1266755)
__kmalloc_cache_noprof(0.102% 1296/1266755)
...
allocinfo_show(21.287% 356378/1674191)
allocinfo_next(1.530% 25621/1674191)
codetag_next_ct() takes major part.
A private data alloced at open() time can be used to carry iterator alive
across read() calls, and avoid the memory allocation and iterator reset
for each read(). This way, only O(1) memory allocation and O(n) steps
iterating, and `time` shows performance improvement from ~7ms to ~4ms.
Profiling with the change:
vfs_read(99.865% 1581073/1583214)
proc_reg_read_iter(99.485% 1572934/1581073)
seq_read_iter(99.846% 1570519/1572934)
allocinfo_show(87.428% 1373074/1570519)
seq_buf_printf(83.695% 1149196/1373074)
seq_buf_putc(1.917% 26321/1373074)
_find_next_bit(1.531% 21023/1373074)
...
codetag_to_text(0.490% 6727/1373074)
...
allocinfo_next(6.275% 98543/1570519)
...
allocinfo_start(0.369% 5790/1570519)
...
Now seq_buf_printf() takes major part.

alloc_tag: add sequence number for module and iterator
Codetag iterator use <id,address> pair to guarantee the validness. But both id and address can be reused, there is theoretical possibility when module inserted right after another module removed, kmalloc returns an address same as the address kfree by previous module and IDR key reuses the key recently removed. Add a sequence number to codetag_module and code_iterator, the sequence number is strickly incremented whenever a module is loaded. An iterator is valid if and only if its sequence number match codetag_module's.

xarray: add a BUG_ON() to ensure caller is not sibling
Suppose xas is pointing somewhere near the end of the multi-entry batch. Then it may happen that the computed slot already falls beyond the batch, thus breaking the loop due to !xa_is_sibling(), and computing the wrong order. For example, suppose we have a shift-6 node having an order-9 entry => 8 - 1 = 7 siblings, so assume the slots are at offset 0 till 7 in this node. If xas->xa_offset is 6, then the code will compute order as 1 + xas->xa_node->shift = 7. Therefore, the order computation must start from the beginning of the multi-slot entries, that is, the non-sibling entry. Thus ensure that the caller is aware of this by triggering a BUG when the entry is a sibling entry. Note that this BUG_ON() is only active while running selftests, so there is no overhead in a running kernel.

On destroy, we should set each node dead. But current code miss this when

The reason is mt_destroy_walk() leverage mte_destroy_descend() to set node
dead, but this is skipped since the only root node is a leaf.

lib/alloc_tag: do not acquire non-existent lock in alloc_tag_top_users()
alloc_tag_top_users() attempts to lock alloc_tag_cttype->mod_lock even
when the alloc_tag_cttype is not allocated because:
1) alloc tagging is disabled because mem profiling is disabled
(!alloc_tag_cttype)
2) alloc tagging is enabled, but not yet initialized (!alloc_tag_cttype)
3) alloc tagging is enabled, but failed initialization
(!alloc_tag_cttype or IS_ERR(alloc_tag_cttype))
In all cases, alloc_tag_cttype is not allocated, and therefore
alloc_tag_top_users() should not attempt to acquire the semaphore.
This leads to a crash on memory allocation failure by attempting to
acquire a non-existent semaphore:

As I did for sha512_blocks(), reorganize x86's sha256_blocks() to be just a static_call. To achieve that, for each assembly function add a C function that handles the kernel-mode FPU section and fallback. While this increases total code size slightly, the amount of code actually executed on a given system does not increase, and it is slightly more efficient since it eliminates the extra static_key. It also makes the assembly functions be called with standard direct calls instead of static calls, eliminating the need for ANNOTATE_NOENDBR.

lib/crypto: sha256: Consolidate into single module
Consolidate the CPU-based SHA-256 code into a single module, following what I did with SHA-512: - Each arch now provides a header file lib/crypto/$(SRCARCH)/sha256.h, replacing lib/crypto/$(SRCARCH)/sha256.c. The header defines sha256_blocks() and optionally sha256_mod_init_arch(). It is included by lib/crypto/sha256.c, and thus the code gets built into the single libsha256 module, with proper inlining and dead code elimination. - sha256_blocks_generic() is moved from lib/crypto/sha256-generic.c into lib/crypto/sha256.c. It's now a static function marked with __maybe_unused, so the compiler automatically eliminates it in any cases where it's not used. - Whether arch-optimized SHA-256 is buildable is now controlled centrally by lib/crypto/Kconfig instead of by lib/crypto/$(SRCARCH)/Kconfig. The conditions for enabling it remain the same as before, and it remains enabled by default. - Any additional arch-specific translation units for the optimized SHA-256 code (such as assembly files) are now compiled by lib/crypto/Makefile instead of lib/crypto/$(SRCARCH)/Makefile.

lib/crypto: sha256: Propagate sha256_block_state type to implementations
The previous commit made the SHA-256 compression function state be strongly typed, but it wasn't propagated all the way down to the implementations of it. Do that now.

lib/crypto: sha256: Make library API use strongly-typed contexts
Currently the SHA-224 and SHA-256 library functions can be mixed arbitrarily, even in ways that are incorrect, for example using sha224_init() and sha256_final(). This is because they operate on the same structure, sha256_state. Introduce stronger typing, as I did for SHA-384 and SHA-512. Also as I did for SHA-384 and SHA-512, use the names *_ctx instead of *_state. The *_ctx names have the following small benefits: - They're shorter. - They avoid an ambiguity with the compression function state. - They're consistent with the well-known OpenSSL API. - Users usually name the variable 'sctx' anyway, which suggests that *_ctx would be the more natural name for the actual struct. Therefore: update the SHA-224 and SHA-256 APIs, implementation, and calling code accordingly. In the new structs, also strongly-type the compression function state.

lib/crypto: sha256: Add sha224() and sha224_update()
Add a one-shot SHA-224 computation function sha224(), for consistency with sha256(), sha384(), and sha512() which all already exist. Similarly, add sha224_update(). While for now it's identical to sha256_update(), omitting it makes the API harder to use since users have to "know" which functions are the same between SHA-224 and SHA-256. Also, this is a prerequisite for using different context types for each.

lib/crypto: sha256: Remove sha256_blocks_simd()
Instead of having both sha256_blocks_arch() and sha256_blocks_simd(), instead have just sha256_blocks_arch() which uses the most efficient implementation that is available in the calling context. This is simpler, as it reduces the API surface. It's also safer, since sha256_blocks_arch() just works in all contexts, including contexts where the FPU/SIMD/vector registers cannot be used. This doesn't mean that SHA-256 computations *should* be done in such contexts, but rather we should just do the right thing instead of corrupting a random task's registers. Eliminating this footgun and simplifying the code is well worth the very small performance cost of doing the check. Note: in the case of arm and arm64, what used to be sha256_blocks_arch() is renamed back to its original name of sha256_block_data_order(). sha256_blocks_arch() is now used for the higher-level dispatch function. This renaming also required an update to lib/crypto/arm64/sha512.h, since sha2-armv8.pl is shared by both SHA-256 and SHA-512.

lib/crypto: sha256: Reorder some code
First, move the declarations of sha224_init/update/final to be just above the corresponding SHA-256 code, matching the order that I used for SHA-384 and SHA-512. In sha2.h, the end result is that SHA-224, SHA-256, SHA-384, and SHA-512 are all in the logical order. Second, move sha224_block_init() and sha256_block_init() to be just below crypto_sha256_state. In later changes, these functions as well as struct crypto_sha256_state will no longer be used by the library functions. They'll remain just for some legacy offload drivers. This gets them into a logical place in the file for that. No code changes other than reordering.

error: uninitialized symbol 'errmsg'.
This static checker warning only showed up after a recent refactoring

group_cpu_evenly()

alloc_nodes_groups()
# allocated total groups may be less than numgrps when
# active total CPU number is less then numgrps
In this case, the caller will do an out of bound access because the
caller assumes the masks returned has numgrps.
Return the number of groups created so the caller can limit the access
range accordingly.

lib/crc: Prepare for arch-optimized code in subdirs of lib/crc/
Rework how lib/crc/ supports arch-optimized code. First, instead of the arch-optimized CRC code being in arch/$(SRCARCH)/lib/, it will now be in lib/crc/$(SRCARCH)/. Second, the API functions (e.g. crc32c()), arch-optimized functions (e.g. crc32c_arch()), and generic functions (e.g. crc32c_base()) will now be part of a single module for each CRC type, allowing better inlining and dead code elimination. The second change is made possible by the first. As an example, consider CONFIG_CRC32=m on x86. We'll now have just crc32.ko instead of both crc32-x86.ko and crc32.ko. The two modules were already coupled together and always both got loaded together via direct symbol dependency, so the separation provided no benefit. Note: later I'd like to apply the same design to lib/crypto/ too, where often the API functions are out-of-line so this will work even better. In those cases, for each algorithm we currently have 3 modules all coupled together, e.g. libsha256.ko, libsha256-generic.ko, and sha256-x86.ko. We should have just one, inline things properly, and rely on the compiler's dead code elimination to decide the inclusion of the generic code instead of manually setting it via kconfig. Having arch-specific code outside arch/ was somewhat controversial when Zinc proposed it back in 2018. But I don't think the concerns are warranted. It's better from a technical perspective, as it enables the improvements mentioned above. This model is already successfully used in other places in the kernel such as lib/raid6/. The community of each architecture still remains free to work on the code, even if it's not in arch/. At the time there was also a desire to put the library code in the same files as the old-school crypto API, but that was a mistake; now that the library is separate, that's no longer a constraint either.

lib/crc32: Remove unused combination support
Remove crc32_le_combine() and crc32_le_shift(), since they are no longer used. Although combination is an interesting thing that can be done with CRCs, it turned out that none of the users of it in the kernel were even close to being worthwhile. All were much better off simply chaining the CRCs or processing zeroes. Let's remove the CRC32 combination code for now. It can come back (potentially optimized with carryless multiplication instructions) if there is ever a case where it would actually be worthwhile.

lib/crypto: mips/chacha: Fix clang build and remove unneeded byteswap
The MIPS32r2 ChaCha code has never been buildable with the clang
assembler. First, clang doesn't support the 'rotl' pseudo-instruction:
error: unknown instruction, did you mean: rol, rotr?
Second, clang requires that both operands of the 'wsbh' instruction be
explicitly given:
error: too few operands for instruction
To fix this, align the code with the real instruction set by (1) using
the real instruction 'rotr' instead of the nonstandard pseudo-
instruction 'rotl', and (2) explicitly giving both operands to 'wsbh'.
To make removing the use of 'rotl' a bit easier, also remove the
unnecessary special-casing for big endian CPUs at
.Lchacha_mips_xor_bytes. The tail handling is actually
endian-independent since it processes one byte at a time. On big endian
CPUs the old code byte-swapped SAVED_X, then iterated through it in
reverse order. But the byteswap and reverse iteration canceled out.
Tested with chacha20poly1305-selftest in QEMU using "-M malta" with both
little endian and big endian mips32r2 kernels.

lib/crypto: x86: Move arch/x86/lib/crypto/ into lib/crypto/
Move the contents of arch/x86/lib/crypto/ into lib/crypto/x86/. The new code organization makes a lot more sense for how this code actually works and is developed. In particular, it makes it possible to build each algorithm as a single module, with better inlining and dead code elimination.

Since HMAC support is commonly needed and is fairly simple, include it as a first-class citizen of the SHA-512 library.

Add basic support for SHA-384 and SHA-512 to lib/crypto/. Various in-kernel users will be able to use this instead of the old-school crypto API, which is harder to use and has more overhead. The basic support added by this commit consists of the API and its documentation, backed by a C implementation of the algorithms. sha512_block_generic() is derived from crypto/sha512_generic.c.

This should only manifest on MMU=n kernels. * A fix for context save/restore on systems using the T-Head vector extensions. * A fix for a conflicting "+r"/"r" register constraint in the VDSO getrandom syscall wrapper, which is undefined behavior in clang. * A fix for a missing register clobber in the RVV raid6 implementation. This manifests as a NULL pointer reference on some compilers, but could trigger in other ways. * Misaligned accesses from userspace at faulting addresses are now handled correctly. * A fix for an incorrect optimization that allowed access_ok() to mark invalid addresses as accessible, which can result in userspace triggering BUG()s. * A few fixes for build warnings, and an update to Drew's email address. -----BEGIN PGP SIGNATURE----- iQJNBAABCAA3FiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmhe80kZHHBhbG1lcmRh YmJlbHRAZ29vZ2xlLmNvbQAKCRAuExnzX7sYicV6EACT/5384tdpYSQ6WQ4K2mT2 XxPbrYTJ4jrhZMugnfe1LHBokeBGoGPRK11Dr/PyNJ71oeeDF7opv0kxAfqsiOO3 QrwUE/4zhGgEzs7Z6D8UgYiqVDfb4aMU+oZ0qIfy+r+cB4F9M65TIejdVj99V6Hu V9cjJ4ABM9KfaZhD5BvoqflblYtwuSg/VYsUmZH6aolDyadzTy4rWcPk1jdFJDQt tIEsXjc92KNAKGSFe8DDZjjhM216Th/nUsZcxI2DLRQjjHPNEthkAgLNltQGocU9 gJ8U3IqfazgnqcZAlrr7BXlWYlBFH/wGXVsxuBL5LPov19RcTkjl2PWH7T08yyuv lCGXrfkz3hSu+Sa9A40w4LptrKNWUEFJztaPkQ68gn1ZQP7KB/rsWp+82dCqhT35 RNxmSznLyTsHFRXR2n9fZrWX/F/LwxY7vaH7cTZUDkMHI8F7WP/3tlihxPCQaUHD dIb+osch8puxG3YjO7H99WrpJamNNw3+L1l2lXtXTRmXdxE+x7fyatmHX98mY8IC 7NXGOdNNIEvv4i9vzSphYQHBOT3tBVfz40z878qfSL3xYHG3ZLMIsWuynaWDMI73 QprwAPmdFxdmJrHyIY6gIiyrscNHz5WLMjkG4K+jXlsBBmDxJMAY5zzNdFoeUVDz tjnDY4DYc4fCnteKSA/hpw== =42TO -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-5.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V Fixes for 5.16-rc4 - .rodata is no longer linkd into PT_DYNAMIC.

kunit: Make default kunit_test timeout configurable via both a module parameter and a Kconfig option
To accommodate varying hardware performance and use cases, the default kunit test case timeout (currently 300 seconds) is now configurable. Users can adjust the timeout by either setting the 'timeout' module parameter or the KUNIT_DEFAULT_TIMEOUT Kconfig option to their desired timeout in seconds.

ref_tracker: do xarray and workqueue job initializations earlier
The kernel test robot reported an oops that occurred when attempting to
deregister a dentry from the xarray during subsys_initcall().
The ref_tracker xarrays and workqueue job are being initialized in
late_initcall() which is too late. Move those to postcore_initcall()
instead.

mm/alloc_tag: fix the kmemleak false positive issue in the allocation of the percpu variable tag->counters
When loading a module, as long as the module has memory allocation
operations, kmemleak produces a false positive report that resembles the
following:
unreferenced object (percpu) 0x7dfd232a1650 (size 16):
comm "modprobe", pid 1301, jiffies 4294940249
hex dump (first 16 bytes on cpu 2):

This is because the module can only indirectly reference
alloc_tag_counters through the alloc_tag section, which misleads kmemleak.
However, we don't have a kmemleak ignore interface for percpu allocations
yet. So let's create one and invoke it for tag->counters.

kunit: Adjust kunit_test timeout based on test_{suite,case} speed
Currently, the in-kernel kunit test case timeout is 300 seconds. (There is a separate timeout mechanism for the whole test execution in kunit.py, but that's unrelated.) However, tests marked 'slow' or 'very slow' may timeout, particularly on slower machines. Implement a multiplier to the test-case timeout, so that slower tests have longer to complete: - DEFAULT -> 1x default timeout - KUNIT_SPEED_SLOW -> 3x default timeout - KUNIT_SPEED_VERY_SLOW -> 12x default timeout A further change is planned to allow user configuration of the default/base timeout to allow people with faster or slower machines to adjust these to their use-cases.

char: misc: add test cases
Add test cases for static and dynamic minor number allocation and
deallocation.
While at it, improve description and test suite name.
Some of the cases include:
- that static and dynamic allocation reserved the expected minors.
- that registering duplicate minors or duplicate names will fail.
- that failing to create a sysfs file (due to duplicate names) will
deallocate the dynamic minor correctly.
- that dynamic allocation does not allocate a minor number in the static
range.
- that there are no collisions when mixing dynamic and static allocations.
- that opening devices with various minor device numbers work.
- that registering a static number in the dynamic range won't conflict with
a dynamic allocation.
This last test verifies the bug fixed by commit

maple_tree: fix MA_STATE_PREALLOC flag in mas_preallocate()
Temporarily clear the preallocation flag when explicitly requesting
allocations. Pre-existing allocations are already counted against the
request through mas_node_count_gfp(), but the allocations will not happen
if the MA_STATE_PREALLOC flag is set. This flag is meant to avoid
re-allocating in bulk allocation mode, and to detect issues with
preallocation calculations.
The MA_STATE_PREALLOC flag should also always be set on zero allocations
so that detection of underflow allocations will print a WARN_ON() during
consumption.
User visible effect of this flaw is a WARN_ON() followed by a null pointer
dereference when subsequent requests for larger number of nodes is
ignored, such as the vma merge retry in mmap_region() caused by drivers
altering the vma flags (which happens in v6.6, at least)

ref_tracker: automatically register a file in debugfs for a ref_tracker_dir
Currently, there is no convenient way to see the info that the ref_tracking infrastructure collects. Attempt to create a file in debugfs when called from ref_tracker_dir_init(). The file is given the name "class@%px", as having the unmodified address is helpful for debugging. This should be safe since this directory is only accessible by root While ref_tracker_dir_init() is generally called from a context where sleeping is OK, ref_tracker_dir_exit() can be called from anywhere. Thus, dentry cleanup must be handled asynchronously. Add a new global xarray that has entries with the ref_tracker_dir pointer as the index and the corresponding debugfs dentry pointer as the value. Instead of removing the debugfs dentry, have ref_tracker_dir_exit() set a mark on the xarray entry and schedule a workqueue job. The workqueue job then walks the xarray looking for marked entries, and removes their xarray entries and the debugfs dentries. Because of this, the debugfs dentry can outlive the corresponding ref_tracker_dir. Have ref_tracker_debugfs_show() take extra care to ensure that it's safe to dereference the dir pointer before using it.

ref_tracker: add a static classname string to each ref_tracker_dir
A later patch in the series will be adding debugfs files for each ref_tracker that get created in ref_tracker_dir_init(). The format will be "class@%px". The current "name" string can vary between ref_tracker_dir objects of the same type, so it's not suitable for this purpose. Add a new "class" string to the ref_tracker dir that describes the the type of object (sans any individual info for that object). Also, in the i915 driver, gate the creation of debugfs files on whether the dentry pointer is still set to NULL. CI has shown that the ref_tracker_dir can be initialized more than once.

ref_tracker: have callers pass output function to pr_ostream()
In a later patch, we'll be adding a 3rd mechanism for outputting ref_tracker info via seq_file. Instead of a conditional, have the caller set a pointer to an output function in struct ostream. As part of this, the log prefix must be explicitly passed in, as it's too late for the pr_fmt macro.

As Thomas Weißschuh points out [1], it is now preferable to use %p instead of hashed pointers with printk(), since raw pointers should no longer be leaked into the kernel log.

raid6: riscv: Fix NULL pointer dereference caused by a missing clobber
When running the raid6 user-space test program on RISC-V QEMU, there's a
segmentation fault which seems caused by accessing a NULL pointer,
which is the pointer variable p/q in raid6_rvv*_gen/xor_syndrome_real(),
p/q should have been equal to dptr[x], but when I use GDB command to
see its value, which was 0x10 like below:
"
Program received signal SIGSEGV, Segmentation fault.
0x0000000000011062 in raid6_rvv2_xor_syndrome_real (disks=<optimized out>, start=0, stop=<optimized out>, bytes=4096, ptrs=<optimized out>) at rvv.c:386
(gdb) p p
$1 = (u8 *) 0x10 <error: Cannot access memory at address 0x10>
"
The issue was found to be related with:
1) Compile optimization
There's no segmentation fault if compiling the raid6test program with
the optimization flag -O0.
2) The RISC-V vector command vsetvli
If not used t0 as the first parameter in vsetvli, there's no
segmentation fault either.
This patch selects the 2nd solution to fix the issue.
[Palmer: The actual issue here is a missing clobber in the vsetvli code.
It's a little tricky: we've already probed for VLENB so we don't need to
look at the output register, we just need to have an X register in the
instruction as that's the form required to actually set VL. Thus we
clobber a register, and without describing that we end up breaking
compilers.]

slab: Decouple slab_debug and no_hash_pointers
Some system owners use slab_debug=FPZ (or similar) as a hardening option,
but do not want to be forced into having kernel addresses exposed due
to the implicit "no_hash_pointers" boot param setting.[1]
Introduce the "hash_pointers" boot param, which defaults to "auto"
(the current behavior), but also includes "always" (forcing on hashing
even when "slab_debug=..." is defined), and "never". The existing
"no_hash_pointers" boot param becomes an alias for "hash_pointers=never".
This makes it possible to boot with "slab_debug=FPZ hash_pointers=always".

iov_iter: use iov_offset for length calculation in iov_iter_aligned_bvec
If iov_offset is non-zero, then we need to consider iov_offset in length
calculation, otherwise we might pass smaller IOs such as 512 bytes, in
below scenario [1].
This issue is reproducible using lib-uring test/fixed-seg.c application
with fixed buffer on a 512 LBA formatted device.
[1]
At present we pass the alignment check, for 512 LBA formatted devices,
len_mask = 511 when IO is smaller, i->count = 512 has an offset,
i->io_offset = 3584 with bvec values, bvec->bv_offset = 256,
bvec->bv_len = 3840. In short, the first 256 bytes are in the current
page, next 256 bytes are in the another page. Ideally we expect to
fail the IO.
I can think of 2 userspace scenarios where we experience this.
a: From userspace, we observe a different behaviour when device LBA
size is 512 vs 4096 bytes. For 4096 LBA formatted device, I see the
same liburing test [2] failing, whereas 512 the test passes without
this. This is reproducible everytime.
[2] https://github.com/axboe/liburing/
b: Although I was not able to reproduce the below condition, but I
suspect below case should be possible from user space for devices
with 512 LBA formatted device. Lets say from userspace while
allocating a virtually single chunk of memory, if we get 2 physical
chunk of memory, and IO happens to be at the boundary of first
physical chunk with length crossing first chunk, then we allow IOs
to proceed and hence we might map wrong physical address length and
proceed with IO rather than failing.

alloc_tag: handle module codetag load errors as module load failures
Failures inside codetag_load_module() are currently ignored. As a result an error there would not cause a module load failure and freeing of the associated resources. Correct this behavior by propagating the error code to the caller and handling possible errors. With this change, error to allocate percpu counters, which happens at this stage, will not be ignored and will cause a module load failure and freeing of resources. With this change we also do not need to disable memory allocation profiling when this error happens, instead we fail to load the module.

iov: remove copy_page_from_iter_atomic()
All callers now use copy_folio_from_iter_atomic(), so convert copy_page_from_iter_atomic(). While I'm in there, use kmap_local_folio() and pagefault_disable() instead of kmap_atomic(). That allows preemption and/or task migration to happen during the copy_from_user(). Also use the new folio_test_partial_kmap() predicate instead of open-coding it.

- The 3 patch series "hung_task: extend blocking task stacktrace dump to
semaphore" from Lance Yang enhances the hung task detector. The
detector presently dumps the blocking tasks's stack when it is blocked
on a mutex. Lance's series extends this to semaphores.
- The 2 patch series "nilfs2: improve sanity checks in dirty state
propagation" from Wentao Liang addresses a couple of minor flaws in
nilfs2.
- The 2 patch series "scripts/gdb: Fixes related to lx_per_cpu()" from
Illia Ostapyshyn fixes a couple of issues in the gdb scripts.
- The 9 patch series "Support kdump with LUKS encryption by reusing LUKS
volume keys" from Coiby Xu addresses a usability problem with kdump.
When the dump device is LUKS-encrypted, the kdump kernel may not have
the keys to the encrypted filesystem. A full writeup of this is in the
series [0/N] cover letter.
- The 2 patch series "sysfs: add counters for lockups and stalls" from
Max Kellermann adds /sys/kernel/hardlockup_count and
/sys/kernel/hardlockup_count and /sys/kernel/rcu_stall_count.
- The 3 patch series "fork: Page operation cleanups in the fork code"
from Pasha Tatashin implements a number of code cleanups in fork.c.
- The 3 patch series "scripts/gdb/symbols: determine KASLR offset on
s390 during early boot" from Ilya Leoshkevich fixes some s390 issues in
the gdb scripts.

- The 11 patch series "Add folio_mk_pte()" from Matthew Wilcox
simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - The 8 patch series "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - The 3 patch series "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - The 2 patch series "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction. In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - The 8 patch series "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - The 6 patch series "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments. At this time we can alter only "system call information that are used by strace system call tampering, namely, syscall number, syscall arguments, and syscall return value. This series should have been incorporated into mm.git's "non-MM" branch, but I goofed. - The 3 patch series "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl against /proc/pid/pagemap. This permits CRIU to more efficiently get at the info about guard regions. - The 2 patch series "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan implements that fix. No runtime effect is expected because validate_page_before_insert() happens to fix up this error. - The 3 patch series "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David Hildenbrand basically brings uprobe text poking into the current decade. Remove a bunch of hand-rolled implementation in favor of using more current facilities. - The 3 patch series "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman Khandual provides enhancements and generalizations to the pte dumping code. This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - The 12 patch series "Always call constructor for kernel page tables" from Kevin Brodsky "ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables". This permits the addition of more functionality such as "insert hooks to protect page tables". This change does result in various architectures performing unnecesary work, but this is fixed up where it is anticipated to occur. - The 9 patch series "Rust support for mm_struct, vm_area_struct, and mmap" from Alice Ryhl adds plumbing to permit Rust access to core MM structures. - The 3 patch series "fix incorrectly disallowed anonymous VMA merges" from Lorenzo Stoakes takes advantage of some VMA merging opportunities which we've been missing for 15 years. - The 4 patch series "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from SeongJae Park optimizes process_madvise()'s TLB flushing. Instead of flushing each address range in the provided iovec, we batch the flushing across all the iovec entries. The syscall's cost was approximately halved with a microbenchmark which was designed to load this particular operation. - The 6 patch series "Track node vacancy to reduce worst case allocation counts" from Sidhartha Kumar makes the maple tree smarter about its node preallocation. stress-ng mmap performance increased by single-digit percentages and the amount of unnecessarily preallocated memory was dramaticelly reduced. - The 3 patch series "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes a few unnecessary things which Baoquan noted when reading the code. - The 3 patch series ""Enhance sysfs handling for memory hotplug in weighted interleave" from Rakie Kim "enhances the weighted interleave policy in the memory management subsystem by improving sysfs handling, fixing memory leaks, and introducing dynamic sysfs updates for memory hotplug support". Fixes things on error paths which we are unlikely to hit. - The 7 patch series "mm/damon: auto-tune DAMOS for NUMA setups including tiered memory" from SeongJae Park introduces new DAMOS quota goal metrics which eliminate the manual tuning which is required when utilizing DAMON for memory tiering. - The 5 patch series "mm/vmalloc.c: code cleanup and improvements" from Baoquan He provides cleanups and small efficiency improvements which Baoquan found via code inspection. - The 2 patch series "vmscan: enforce mems_effective during demotion" from Gregory Price "changes reclaim to respect cpuset.mems_effective during demotion when possible". because "presently, reclaim explicitly ignores cpuset.mems_effective when demoting, which may cause the cpuset settings to violated." "This is useful for isolating workloads on a multi-tenant system from certain classes of memory more consistently." - The 2 patch series ""Clean up split_huge_pmd_locked() and remove unnecessary folio pointers" from Gavin Guo provides minor cleanups and efficiency gains in in the huge page splitting and migrating code. - The 3 patch series "Use kmem_cache for memcg alloc" from Huan Yang creates a slab cache for `struct mem_cgroup', yielding improved memory utilization. - The 4 patch series "add max arg to swappiness in memory.reclaim and lru_gen" from Zhongkun He adds a new "max" argument to the "swappiness=" argument for memory.reclaim MGLRU's lru_gen. This directs proactive reclaim to reclaim from only anon folios rather than file-backed folios. - The 17 patch series "kexec: introduce Kexec HandOver (KHO)" from Mike Rapoport is the first step on the path to permitting the kernel to maintain existing VMs while replacing the host kernel via file-based kexec. At this time only memblock's reserve_mem is preserved. - The 7 patch series "mm: Introduce for_each_valid_pfn()" from David Woodhouse provides and uses a smarter way of looping over a pfn range. By skipping ranges of invalid pfns. - The 2 patch series "sched/numa: Skip VMA scanning on memory pinned to one NUMA node via cpuset.mems" from Libo Chen removes a lot of pointless VMA scanning when a task is pinned a single NUMA mode. Dramatic performance benefits were seen in some real world cases. - The 2 patch series "JFS: Implement migrate_folio for jfs_metapage_aops" from Shivank Garg addresses a warning which occurs during memory compaction when using JFS. - The 4 patch series "move all VMA allocation, freeing and duplication logic to mm" from Lorenzo Stoakes moves some VMA code from kernel/fork.c into the more appropriate mm/vma.c. - The 6 patch series "mm, swap: clean up swap cache mapping helper" from Kairui Song provides code consolidation and cleanups related to the folio_index() function. - The 2 patch series "mm/gup: Cleanup memfd_pin_folios()" from Vishal Moola does that. - The 8 patch series "memcg: Fix test_memcg_min/low test failures" from Waiman Long addresses some bogus failures which are being reported by the test_memcontrol selftest. - The 3 patch series "eliminate mmap() retry merge, add .mmap_prepare hook" from Lorenzo Stoakes commences the deprecation of file_operations.mmap() in favor of the new file_operations.mmap_prepare(). The latter is more restrictive and prevents drivers from messing with things in ways which, amongst other problems, may defeat VMA merging. - The 4 patch series "memcg: decouple memcg and objcg stocks"" from Shakeel Butt decouples the per-cpu memcg charge cache from the objcg's one. This is a step along the way to making memcg and objcg charging NMI-safe, which is a BPF requirement. - The 6 patch series "mm/damon: minor fixups and improvements for code, tests, and documents" from SeongJae Park is "yet another batch of miscellaneous DAMON changes. Fix and improve minor problems in code, tests and documents." - The 7 patch series "memcg: make memcg stats irq safe" from Shakeel Butt converts memcg stats to be irq safe. Another step along the way to making memcg charging and stats updates NMI-safe, a BPF requirement. - The 4 patch series "Let unmap_hugepage_range() and several related functions take folio instead of page" from Fan Ni provides folio conversions in the hugetlb code. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCaDt5qgAKCRDdBJ7gKXxA ju6XAP9nTiSfRz8Cz1n5LJZpFKEGzLpSihCYyR6P3o1L9oe3mwEAlZ5+XAwk2I5x Qqb/UGMEpilyre1PayQqOnct3aSL9Ao= =tYYm -----END PGP SIGNATURE----- Merge tag 'mm-stable-2025-05-31-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - "Add folio_mk_pte()" from Matthew Wilcox simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction.

require gcc-8 and binutils-2.30
x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those. Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler but additionally include toolchains that remain supported. With the new minimum toolchain versions, a number of workarounds for older versions can be dropped, in particular on x86_64 and arm64. Importantly, the updated compiler version allows removing two of the five remaining gcc plugins, as support for sancov and structeak features is already included in modern compiler versions. I tried collecting the known changes that are possible based on the new toolchain version, but expect that more cleanups will be possible. Since this touches multiple architectures, I merged the patches through the asm-generic tree. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmg6vNMACgkQmmx57+YA GNkOmg/+LtR9B2P27GPBeG8HnLTZ8hKELiyYeSk6ZFgQv5hevE37HV35Yru7e7gu wcF6CgYr8ff4CVcHM7y0790oGew1thkqq5CklFIH0EwCDJx/mWfZR1SS2jfZIEWM HSDOlQQd1S8oWia14tSnQos3nW3CB9/ABVTHH+Wvl3xn48WMRvgK2LJgGLuxJrt8 5DD9auHiLjchWB5tB4DU98IgWWgFUGMTsI6IayZ4dkF4CdWqd89h0Y3pjJYeBgHS mPxzR2q8WjEmG9hp7QuZQgn/pAYleJAwHvvkoLrkQ2ieqx3FjWiwFbQp4CG1Sc8L eBR1lnkqS2z/e7xJLfe86fOoKWWu4I0tZKhRan/0+UOGm5nXrGpqSxKS8ZDsRuAp 3fvyhIp1cYSa7Xkok8BFhLEFR0tguXJXnXBc3tWE5VXIfFNd0Ohh1GUYhXDAqWKh i0jN9dSNhokM3AqBi6qZl5kmBnRA3UsIaOg3QRrqN8IlBPp+u7i5xsrJIUWvD95o TO06admmLcCJT8n6ZfNVfRjBgzu8+t54UVaDx9YYwxoNGOSFwqOb8CSPTWPxLmDr RKDUOvO8DBlP7uFz9neP+LxluA3DjurRZvb0z0AmCZ8/RXEmTMCyfP5a6esxquXt 0Bqo6hM9q+TeXTHNS1CNvqLSWWikw+AzS/ZPPvriYFn5lxtbq6c= =pdDC -----END PGP SIGNATURE----- Merge tag 'gcc-minimum-version-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull compiler version requirement update from Arnd Bergmann: "Require gcc-8 and binutils-2.30 x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those.

ARM:
* Add large stage-2 mapping (THP) support for non-protected guests when pKVM is enabled, clawing back some performance. * Enable nested virtualisation support on systems that support it, though it is disabled by default. * Add UBSAN support to the standalone EL2 object used in nVHE/hVHE and protected modes. * Large rework of the way KVM tracks architecture features and links them with the effects of control bits. While this has no functional impact, it ensures correctness of emulation (the data is automatically extracted from the published JSON files), and helps dealing with the evolution of the architecture. * Significant changes to the way pKVM tracks ownership of pages, avoiding page table walks by storing the state in the hypervisor's vmemmap. This in turn enables the THP support described above. * New selftest checking the pKVM ownership transition rules * Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests even if the host didn't have it. * Fixes for the address translation emulation, which happened to be rather buggy in some specific contexts. * Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N from the number of counters exposed to a guest and addressing a number of issues in the process. * Add a new selftest for the SVE host state being corrupted by a guest. * Keep HCR_EL2.xMO set at all times for systems running with the kernel at EL2, ensuring that the window for interrupts is slightly bigger, and avoiding a pretty bad erratum on the AmpereOne HW. * Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers from a pretty bad case of TLB corruption unless accesses to HCR_EL2 are heavily synchronised. * Add a per-VM, per-ITS debugfs entry to dump the state of the ITS tables in a human-friendly fashion. * and the usual random cleanups. LoongArch: * Don't flush tlb if the host supports hardware page table walks. * Add KVM selftests support. RISC-V: * Add vector registers to get-reg-list selftest * VCPU reset related improvements * Remove scounteren initialization from VCPU reset * Support VCPU reset from userspace using set_mpstate() ioctl x86: * Initial support for TDX in KVM. This finally makes it possible to use the TDX module to run confidential guests on Intel processors. This is quite a large series, including support for private page tables (managed by the TDX module and mirrored in KVM for efficiency), forwarding some TDVMCALLs to userspace, and handling several special VM exits from the TDX module. This has been in the works for literally years and it's not really possible to describe everything here, so I'll defer to the various merge commits up to and including commit |

ubsan: integer-overflow: depend on BROKEN to keep this out of CI
Depending on !COMPILE_TEST isn't sufficient to keep this feature out of
CI because we can't stop it from being included in randconfig builds.
This feature is still highly experimental, and is developed in lock-step
with Clang's Overflow Behavior Types[1]. Depend on BROKEN to keep it
from being enabled by anyone not expecting it.
Link: https://discourse.llvm.org/t/rfc-v2-clang-introduce-overflowbehaviortypes-for-wrapping-and-non-wrapping-arithmetic/86507 [1]
Reported-by: kernel test robot <oliver.sang@intel.com>

Networking changes for 6.16.
Core
----
- Implement the Device Memory TCP transmit path, allowing zero-copy
data transmission on top of TCP from e.g. GPU memory to the wire.
- Move all the IPv6 routing tables management outside the RTNL scope,
under its own lock and RCU. The route control path is now 3x times
faster.
- Convert queue related netlink ops to instance lock, reducing
again the scope of the RTNL lock. This improves the control plane
scalability.
- Refactor the software crc32c implementation, removing unneeded
abstraction layers and improving significantly the related
micro-benchmarks.
- Optimize the GRO engine for UDP-tunneled traffic, for a 10%
performance improvement in related stream tests.
- Cover more per-CPU storage with local nested BH locking; this is a
prep work to remove the current per-CPU lock in local_bh_disable()
on PREMPT_RT.
- Introduce and use nlmsg_payload helper, combining buffer bounds
verification with accessing payload carried by netlink messages.
Netfilter
---------
- Rewrite the procfs conntrack table implementation, improving
considerably the dump performance. A lot of user-space tools
still use this interface.
- Implement support for wildcard netdevice in netdev basechain
and flowtables.
- Integrate conntrack information into nft trace infrastructure.
- Export set count and backend name to userspace, for better
introspection.
BPF
---
- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
programs and can be controlled in similar way to traditional qdiscs
using the "tc qdisc" command.
- Refactor the UDP socket iterator, addressing long standing issues
WRT duplicate hits or missed sockets.
Protocols
---------
- Improve TCP receive buffer auto-tuning and increase the default
upper bound for the receive buffer; overall this improves the single
flow maximum thoughput on 200Gbs link by over 60%.
- Add AFS GSSAPI security class to AF_RXRPC; it provides transport
security for connections to the AFS fileserver and VL server.
- Improve TCP multipath routing, so that the sources address always
matches the nexthop device.
- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
and thus preventing DoS caused by passing around problematic FDs.
- Retire DCCP socket. DCCP only receives updates for bugs, and major
distros disable it by default. Its removal allows for better
organisation of TCP fields to reduce the number of cache lines hit
in the fast path.
- Extend TCP drop-reason support to cover PAWS checks.
Driver API
----------
- Reorganize PTP ioctl flag support to require an explicit opt-in for
the drivers, avoiding the problem of drivers not rejecting new
unsupported flags.
- Converted several device drivers to timestamping APIs.
- Introduce per-PHY ethtool dump helpers, improving the support for
dump operations targeting PHYs.
Tests and tooling
-----------------
- Add support for classic netlink in user space C codegen, so that
ynl-c can now read, create and modify links, routes addresses and
qdisc layer configuration.
- Add ynl sub-types for binary attributes, allowing ynl-c to output
known struct instead of raw binary data, clarifying the classic
netlink output.
- Extend MPTCP selftests to improve the code-coverage.
- Add tests for XDP tail adjustment in AF_XDP.
New hardware / drivers
----------------------
- OpenVPN virtual driver: offload OpenVPN data channels processing
to the kernel-space, increasing the data transfer throughput WRT
the user-space implementation.
- Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.
- Broadcom asp-v3.0 ethernet driver.
- AMD Renoir ethernet device.
- ReakTek MT9888 2.5G ethernet PHY driver.
- Aeonsemi 10G C45 PHYs driver.

Isidoro Vazquez Ramos).
- Fix missing debugfs entry removal on failure by using the devm_
variant in the LVTS thermal driver (AngeloGioacchino Del Regno).
- Remove the unused lvts_debugfs_exit() function as the devm_ variant
introduced before takes care of removing the debugfs entry in the
LVTS driver (Arnd Bergmann).
- Add the Airoha EN7581 thermal sensor support along with its DT
bindings (Christian Marangi).
- Add ipq5018 compatible string DT binding, cleanup and add its suppot
to the QCom Tsens thermal driver (Sricharan Ramabadhran, George
Moussalem).
- Fix comments typos in the Airoha driver (Christian Marangi, Colin Ian
King).
- Address a sparse warning by making a local variable static in the
QCom thermal driver (George Moussalem).

Pull thermal control updates from Rafael Wysocki:
"These add support for a new feature, Platform Temperature Control
(PTC), to the Intel int340x thermal driver, add support for the Airoha
EN7581 thermal sensor and the IPQ5018 platform, fix up the ACPI
thermal zones handling, fix other assorted issues and clean up code
Specifics:
- Add Platform Temperature Control (PTC) support to the Intel int340x
thermal driver (Srinivas Pandruvada)
- Make the Hisilicon thermal driver compile by default when ARCH_HISI
is set (Krzysztof Kozlowski)
- Clean up printk() format by using %pC instead of %pCn in the
bcm2835 thermal driver (Luca Ceresoli)
- Fix variable name coding style in the AmLogic thermal driver
(Enrique Isidoro Vazquez Ramos)
- Fix missing debugfs entry removal on failure by using the devm_
variant in the LVTS thermal driver (AngeloGioacchino Del Regno)
- Remove the unused lvts_debugfs_exit() function as the devm_ variant
introduced before takes care of removing the debugfs entry in the
LVTS driver (Arnd Bergmann)
- Add the Airoha EN7581 thermal sensor support along with its DT
bindings (Christian Marangi)
- Add ipq5018 compatible string DT binding, cleanup and add its
suppot to the QCom Tsens thermal driver (Sricharan Ramabadhran,
George Moussalem)
- Fix comments typos in the Airoha driver (Christian Marangi, Colin
Ian King)
- Address a sparse warning by making a local variable static in the
QCom thermal driver (George Moussalem)
- Fix the usage of the _SCP control method in the driver for ACPI
thermal zones (Armin Wolf)"

sound updates for 6.16-rc1
We've received a lot of activities in this cycle, mostly about leaf
driver codes rather than the core part, but with a good mixture of
code cleanups and new driver additions. Below are some highlights:
* ASoC:
- Support for automatically enumerating DAIs from standards conforming
SoundWire SDCA devices; not much used as of this writing, rather for
future implementations
- Conversion of quite a few drivers to newer GPIO APIs
- Continued cleanups and helper usages in allover places
- Support for a wider range of Intel AVS platforms
- Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32
Everest Semiconductor ES8375 and ES8389, Longsoon-1 AC'97
controllers, nVidia Tegra264, Richtek ALC203 and RT9123 and Rockchip
SAI controllers
* HD-audio:
- Lots of cleanups of TAS2781 codec drivers
- A new HD-audio control bound via ACPI for Nvidia
- Support for Tegra264, Intel WCL, usual new codec quirks
* USB-audio:
- Fix a race at removal of MIDI device
- Pioneer DJM-V10 support, Scarlett2 driver cleanups
* Misc:
- Cleanups of deprecated PCI functions
- Removal of unused / dead function codes

lib/ratelimit: Reduce false-positive and silent misses
Changes ------- * Reduce open-coded use of ratelimit_state structure fields. * Convert the ->missed field to atomic_t. * Count misses that are due to lock contention. * Eliminate jiffies=0 special case. * Reduce ___ratelimit() false-positive rate limiting (Petr Mladek). * Allow zero ->burst to hard-disable rate limiting. * Optimize away atomic operations when a miss is guaranteed. * Warn if ->interval or ->burst are negative (Petr Mladek). * Simplify the resulting code. A smoke test and stress test have been created, but they are not yet ready for mainline. With luck, we will offer them for the v6.17 merge window. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmgzWdgTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jBnZD/wKD+5f8qwEuaib901yLb/s4ZkS3Aly mcPLAcTSFc7jp3c188V2qPAAgobQW+NnOLZ/TuB34tvS/Ngm/Yo1EPiHD2AXPzfY FPlgmjvOQQQo9dfA1PNOegh/aKYhMJrho85cilcM1TojuSSVbo1lG1FbuvqMJ9Ub jPHRB6KaFDnhwJkWHJ4Fjl1z1TQcyxjrBoswEcMCKapNqrm6IiXLvw03Nme3wa7F tr30xue5GV/FyHMa14g/8GSpZ88Lr5VGsOoC0wz2KhfMsZcFRkmslgm8mxHawwXj MbQaW7Th+fD7H0pC/lbHIiKaXvizYbQCPXr4qf5gfqNf4R/BHE1QdSTmP45kjEXO CmZEwwVx8cVdyoY9N9udDhNZly/U83G3F1n38jdM2SCPjn3F8BAanZRwakLEvmCC XUQ0bvzQvJl0LM5ktyaaMZdWf3p6uah7otryCPdsA5V7BFgyx5ZHniXY6v1JgfhX 2nmYRO3vEoQ39Z+vPtu7DvS64oe/aYgkSIoG68rKhSb4S+nIdIZ8zwB1af4Nkk8e YZwlwjIRw+RCu/QET4GXLE1tHQ031kWR/xG8nDnNGE3XCjnfRArAcdMZNDlc3U5k GT1g8zOJR2jmlEvWUZwpmclc1yeHXTK1P9nOHmzhxw26eiXmY353PZcND9Ktnt/a RH550D0vUqFM7A== =ivk+ -----END PGP SIGNATURE----- Merge tag 'ratelimit.2025.05.25a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull rate-limit updates from Paul McKenney: "lib/ratelimit: Reduce false-positive and silent misses: - Reduce open-coded use of ratelimit_state structure fields. - Convert the ->missed field to atomic_t. - Count misses that are due to lock contention. - Eliminate jiffies=0 special case. - Reduce ___ratelimit() false-positive rate limiting (Petr Mladek). - Allow zero ->burst to hard-disable rate limiting. - Optimize away atomic operations when a miss is guaranteed. - Warn if ->interval or ->burst are negative (Petr Mladek). - Simplify the resulting code.

Carve out the resctrl filesystem-related code into fs/resctrl/ so that
multiple architectures can share the fs API for manipulating their
respective hw resource control implementation. This is the second step
in the work towards sharing the resctrl filesystem interface, the next
one being plugging ARM's MPAM into the aforementioned fs API.

alloc_tag: allocate percpu counters for module tags dynamically
When a module gets unloaded it checks whether any of its tags are still in
use and if so, we keep the memory containing module's allocation tags
alive until all tags are unused. However percpu counters referenced by
the tags are freed by free_module(). This will lead to UAF if the memory
allocated by a module is accessed after module was unloaded.
To fix this we allocate percpu counters for module allocation tags
dynamically and we keep it alive for tags which are still in use after
module unloading. This also removes the requirement of a larger
PERCPU_MODULE_RESERVE when memory allocation profiling is enabled because
percpu memory for counters does not need to be reserved anymore.

alloc_tag: check mem_profiling_support in alloc_tag_init
If mem_profiling_support is false, for example by sysctl.vm.mem_profiling=never, alloc_tag_init should skip module tags allocation, codetag type registration and procfs init.

lib/crc32: remove unused support for CRC32C combination
crc32c_combine() and crc32c_shift() are no longer used (except by the KUnit test that tests them), and their current implementation is very slow. Remove them.

kunit: Fix wrong parameter to kunit_deactivate_static_stub()
kunit_deactivate_static_stub() accepts real_fn_addr instead of
replacement_addr. In the case, it always passes NULL to
kunit_deactivate_static_stub().
Fix it.
