A set of changes to consolidate the generic TIF bits accross architectures
All architectures define the same set of generic TIF bits. This makes it pointlessly hard to add a new generic TIF bit or to change an existing one. Provide a generic variant and convert the architectures which utilize the generic entry code over to use it. The TIF space is divided into 16 generic bits and 16 architecture specific bits, which turned out to provide enough space on both sides. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmjaP78THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoTKyD/9NEg3DiN6aM959o1MhvhDk7jNdECXm QOvZ85wJYhCv3Pb7RSgMxJL/dR9aWV2b24TSzEeki0awbR4nPeUz82vExmgS7rWX 9rQLPrOZsrYd76IcAVoV5Ua/g48c+9TM8kLzoZFa9JEYMPmyTEiA3gy4bgab/aov L2b903ZrCNkWRKM1Wz5V8xdyPEzhE+cLhbWoPbeCqfzxqbv4+WWKQlPmqamQw+yq /61Xhq0tmx3+4hn1IB/Rc8yMTbAK0EwN7SHM+l7yaJ3ijlkGSele4S3mKAHv2I3c vODIFwdQ8pRbC1C5eMBnUKRm7Cmf+8CB3m+OIA5ghj10TPFiTUzQ6iG6nUSVniJm QB21LHYSWroeQBRibnT5k7RiW5QjtTQmcsjvO7S2rZ/7CkMr7LMu6kN1P0TSiOvc SKxs3MO72KaRU/JrEjLqvT2tvdpg2hpffg69U0jA1xCeFULE1jrqo3GwL8dPDk7z zKbC73JNg4QJDdi+hIn5nl0fRGVszLzkDum5eyCpCLY/W7BSiQ7q/ayzt9upsSOm uc7sqeIgelQMRDMoMNcQUsMnApT0JHOS74WQ03SfahZESj8eFoOb8pr7vaqu4lfi 6LV4fpwZPBTMDcQ36r2JLuUTqHNHNtWn4xXjQ72ngovIVUL9A2H0DqK+1JhLJ6yX tknZ9WVmWVf+JQ== =6L98 -----END PGP SIGNATURE----- Merge tag 'core-core-2025-09-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull TIF bit unification updates from Thomas Gleixner: "A set of changes to consolidate the generic TIF (thread info flag) bits accross architectures.

- Add functionality to provide runtime firmware updates for the non-x86 parts
of an AMD platform like the security processor (ASP) firmware, modules etc, for example. The intent being that these updates are interim, live fixups before a proper BIOS update can be attempted - Add guest support for AMD's Secure AVIC feature which gives encrypted guests the needed protection against a malicious hypervisor generating unexpected interrupts and injecting them into such guest, thus interfering with its operation in an unexpected and negative manner. The advantage of this scheme is that the guest determines which interrupts and when to accept them vs leaving that to the benevolence (or not) of the hypervisor - Strictly separate the startup code from the rest of the kernel where former is executed from the initial 1:1 mapping of memory. The problem was that the toolchain-generated version of the code was being executed from a different mapping of memory than what was "assumed" during code generation, needing an ever-growing pile of fixups for absolute memory references which are invalid in the early, 1:1 memory mapping during boot. The major advantage of this is that there's no need to check the 1:1 mapping portion of the code for absolute relocations anymore and get rid of the RIP_REL_REF() macro sprinkling all over the place.

scsi: ufs: core: Include UTP error in INT_FATAL_ERRORS
When a UTP error occurs in isolation, UFS is not currently recoverable.
This is because the UTP error is not considered fatal in the error
handling code, leading to either an I/O timeout or an OCS error.
Add the UTP error flag to INT_FATAL_ERRORS so the controller will be
reset in this situation.

nfs/localio: avoid issuing misaligned IO using O_DIRECT
Add nfsd_file_dio_alignment and use it to avoid issuing misaligned IO
using O_DIRECT. Any misaligned DIO falls back to using buffered IO.
Because misaligned DIO is now handled safely, remove the nfs modparam
'localio_O_DIRECT_semantics' that was added to require users opt-in to
the requirement that all O_DIRECT be properly DIO-aligned.
Also, introduce nfs_iov_iter_aligned_bvec() which is a variant of
iov_iter_aligned_bvec() that also verifies the offset associated with
an iov_iter is DIO-aligned. NOTE: in a parallel effort,
iov_iter_aligned_bvec() is being removed along with
iov_iter_is_aligned().
Lastly, add pr_info_ratelimited if underlying filesystem returns
-EINVAL because it was made to try O_DIRECT for IO that is not
DIO-aligned (shouldn't happen, so its best to be louder if it does).
Fixes:

- Add support for new AMD family 0x1a models to amd64_edac
- Add an EDAC driver for the AMD VersalNET memory controller which
reports hw errors from different IP blocks in the fabric using an
IPC-type transport
- Drop the silly static number of memory controllers in the Intel EDAC
drivers (skx, i10nm) in favor of a flexible array so that former
doesn't need to be increased with every new generation which adds more
memory controllers; along with a proper refactoring
- Add support for two Alder Lake-S SOCs to ie31200_edac
- Add an EDAC driver for ADM Cortex A72 cores, and specifically for
reporting L1 and L2 cache errors

With few exceptions, KVM's exported APIs are intended (and safe) for KVM-
internal usage only.
Keep kvm_get_kvm(), kvm_get_kvm_safe(), and kvm_put_kvm() as normal
exports, as they are needed by VFIO, and are generally safe for external
usage (though ideally even the get/put APIs would be KVM-internal, and
VFIO would pin a VM by grabbing a reference to its associated file).
Implement a framework in kvm_types.h in anticipation of providing a macro
to restrict KVM-specific kernel exports, i.e. to provide symbol exports
for KVM if and only if KVM is built as one or more modules.

Scheduler updates for v6.18:
Core scheduler changes:
- Make migrate_{en,dis}able() inline, to improve performance
(Menglong Dong)
- Move STDL_INIT() functions out-of-line (Peter Zijlstra)
- Unify the SCHED_{SMT,CLUSTER,MC} Kconfig (Peter Zijlstra)
Fair scheduling:
- Defer throttling when tasks exit to user-space, to reduce the
chance & impact of throttle-preemption with held locks and
other resources. (Aaron Lu, Valentin Schneider)
- Get rid of sched_domains_curr_level hack for tl->cpumask(),
as the warning was getting triggered on certain topologies.
(Peter Zijlstra)
Misc cleanups & fixes:
- Header cleanups (Menglong Dong)
- Fix race in push_dl_task() (Harshit Agarwal)

KVM SEV-SNP CipherText Hiding support for 6.18
Add support for SEV-SNP's CipherText Hiding, an opt-in feature that prevents unauthorized CPU accesses from reading the ciphertext of SNP guest private memory, e.g. to attempt an offline attack. Instead of ciphertext, the CPU will always read back all FFs when CipherText Hiding is enabled. Add new module parameter to the KVM module to enable CipherText Hiding and control the number of ASIDs that can be used for VMs with CipherText Hiding, which is in effect the number of SNP VMs. When CipherText Hiding is enabled, the hared SEV-ES/SEV-SNP ASID space is split into separate ranges for SEV-ES and SEV-SNP guests, i.e. ASIDs that can be used for CipherText Hiding cannot be used to run SEV-ES guests. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKTobbabEP7vbhhN9OlYIJqCjN/0FAmjXG0EACgkQOlYIJqCj N/1TKQ//UlPcGwoR9cl9V5YRz0b+wNOHNh7JqOTdQsEa00qqIXaAnK+M77Jynvmj YqnQbFCxnQS2pQWkSKv3eJ9Kc9ndTBA7+lL3rrHot6ccks3xM0cHe8Bquu8Of/Ht 1qla1OazrYjJBjFdYCzO+ZQdUvSNAr5RkOPO1KrnHZPELPOQt0+LbxlewRRbKHIj hea8KgmRqmlRJYDJlOGh+G/FFDCFqaeXyOfEkeBuYyCAL60r+0IMHKMwrwlDx/1+ Kzlrf65YuMZlgg7AjhA2mXj4DvlSQkPnMkmkNmNgPXI1XNgHDS/7M1f2m/QbgGV8 Y1D1/GY5u5YD30zDHCmmqPocs5sxrsVoAH8cHalMQsiDlr/HfoKlQ+w0aHEQnHFJ j4GnfCIkyx77tPHeS8e8RJk8qXs+0Bf2bzOAQkv0f/k6JaWhiLzISTFOTyztaf8v m7gPWJORWGZyWVBk+Ad+KGh5Ww2o+sY3aufp81JBT12kC17G0xsHrO1XvUV6YDQ7 wSINQap0TQFY2Lh9Vr1GDNx4jk+YnQOjqKbqd6efyv8No4+j75eaCkbAItma9YVc EPGYa+LaRoC58f7LIChT0uXTAkK7lgdAuGwice7CPsRTjPJqxneIL7u6ohO9jAkz EysFgzsozLynnVUPmXqf5SDots1G5RrAne8Bj+6tLaGxCjW+lLI= =mc41 -----END PGP SIGNATURE----- Merge tag 'kvm-x86-ciphertext-6.18' of https://github.com/kvm-x86/linux into HEAD KVM SEV-SNP CipherText Hiding support for 6.18 Add support for SEV-SNP's CipherText Hiding, an opt-in feature that prevents unauthorized CPU accesses from reading the ciphertext of SNP guest private memory, e.g. to attempt an offline attack.

KVM/arm64 updates for 6.18
- Add support for FF-A 1.2 as the secure memory conduit for pKVM, allowing more registers to be used as part of the message payload. - Change the way pKVM allocates its VM handles, making sure that the privileged hypervisor is never tricked into using uninitialised data. - Speed up MMIO range registration by avoiding unnecessary RCU synchronisation, which results in VMs starting much quicker. - Add the dump of the instruction stream when panic-ing in the EL2 payload, just like the rest of the kernel has always done. This will hopefully help debugging non-VHE setups. - Add 52bit PA support to the stage-1 page-table walker, and make use of it to populate the fault level reported to the guest on failing to translate a stage-1 walk. - Add NV support to the GICv3-on-GICv5 emulation code, ensuring feature parity for guests, irrespective of the host platform. - Fix some really ugly architecture problems when dealing with debug in a nested VM. This has some bad performance impacts, but is at least correct. - Add enough infrastructure to be able to disable EL2 features and give effective values to the EL2 control registers. This then allows a bunch of features to be turned off, which helps cross-host migration. - Large rework of the selftest infrastructure to allow most tests to transparently run at EL2. This is the first step towards enabling NV testing. - Various fixes and improvements all over the map, including one BE fix, just in time for the removal of the feature. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEn9UcU+C1Yxj9lZw9I9DQutE9ekMFAmjVhSsACgkQI9DQutE9 ekOSIg//YdbA/zo17GrLnJnlGdUnS0e3/357n3e5Lypx1UFRDTmNacpVPw4VG/jt eVpQn7AgYwyvKfCq46eD+hBBqNv1XTn4DeXttv7CmVqhCRythsEvDkTBWSt7oYUZ xfYXCMKNhqUElH4AbYYx3y7nb2E9/KVGr+NBn6Vf5c14OZ3MGVc/fyp4jM1ih5dR kcV2onAYohlIGvFEyZMBtJ+jkYkqfIbfxfqCL0RAET0aEBFcmM1aXybWZj47hlLM f2j+E6cFQ0ZzUt+3pFhT75wo43lHGtIFDjVd60uishyU+NXTVvqRmXDTRU4k546W 18HHX1yijbzuXIatVhVRo2hIq3jKU37T9wtj46BejbDHRdAPENEyN/Qopm7rNS+X mCwOT7He6KR+H4rU6nFaTcsS7bNRCvIbZP9i9zb6NElbvXu5QnM8BUQsYFCDUa/n xtbtQlckbo/7zeoUsBDrGj2XmCf0d45FTHb7fdWOYEmMSmJhXYpUKdM4JcLyhKoQ DD0ox2S+pt2lwNw3XOSABdES0KJxCvDASAMIgn2h2sGpY8FxsBcVW/BufXopdafG UeInxWaILp2iCDM4tH2GLjKqlvMAOwcA+mAEZToXypxlJAnYA6J1pXCF8WEaM6+D BGrLli8Zd8JRs87byq6K7tp8oLNzZdliJp73j5jfOHTJA4MnvFI= =iAL3 -----END PGP SIGNATURE----- Merge tag 'kvmarm-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 updates for 6.18 - Add support for FF-A 1.2 as the secure memory conduit for pKVM, allowing more registers to be used as part of the message payload. - Change the way pKVM allocates its VM handles, making sure that the privileged hypervisor is never tricked into using uninitialised data. - Speed up MMIO range registration by avoiding unnecessary RCU synchronisation, which results in VMs starting much quicker. - Add the dump of the instruction stream when panic-ing in the EL2 payload, just like the rest of the kernel has always done.

- Fixes to the TLB match process and TLB invalidation range for
managing the VCNR pseudo-TLB
- Prevent SPE from erroneously profiling guests due to UNKNOWN reset
values in PMSCR_EL1
- Fix save/restore of host MDCR_EL2 to account for eagerly programming
at vcpu_load() on VHE systems
- Correct lock ordering when dealing with VGIC LPIs, avoiding scenarios
where an xarray's spinlock was nested with a *raw* spinlock
- Permit stage-2 read permission aborts which are possible in the case
of NV depending on the guest hypervisor's stage-2 translation
- Call raw_spin_unlock() instead of the internal spinlock API

bonding: fix xfrm offload feature setup on active-backup mode
The active-backup bonding mode supports XFRM ESP offload. However, when
a bond is added using command like `ip link add bond0 type bond mode 1
miimon 100`, the `ethtool -k` command shows that the XFRM ESP offload is
disabled. This occurs because, in bond_newlink(), we change bond link
first and register bond device later. So the XFRM feature update in
bond_option_mode_set() is not called as the bond device is not yet
registered, leading to the offload feature not being set successfully.
To resolve this issue, we can modify the code order in bond_newlink() to
ensure that the bond device is registered first before changing the bond
link parameters. This change will allow the XFRM ESP offload feature to be
correctly enabled.
Fixes:

Documentation: net: add flow control guide and document ethtool API
Introduce a new document, flow_control.rst, to provide a comprehensive guide on Ethernet Flow Control in Linux. The guide explains how flow control works, how autonegotiation resolves pause capabilities, and how to configure it using ethtool and Netlink. In parallel, document the pause and pause-stat attributes in the ethtool.yaml netlink spec. This enables the ynl tool to generate kernel-doc comments for the corresponding enums in the UAPI header, making the C interface self-documenting. Finally, replace the legacy flow control section in phy.rst with a reference to the new document and add pointers in the relevant C source files.

dpll: add phase-offset-avg-factor device attribute to netlink spec
Add dpll device level attribute DPLL_A_PHASE_OFFSET_AVG_FACTOR to allow control over a calculation of reported phase offset value. Attribute is present, if the driver provides such capability, otherwise attribute shall not be present.

arm64 updates for 6.18
Confidential computing:
- Add support for accepting secrets from firmware (e.g. ACPI CCEL)
and mapping them with appropriate attributes.
CPU features:
- Advertise atomic floating-point instructions to userspace.
- Extend Spectre workarounds to cover additional Arm CPU variants.
- Extend list of CPUs that support break-before-make level 2 and
guarantee not to generate TLB conflict aborts for changes of mapping
granularity (BBML2_NOABORT).
- Add GCS support to our uprobes implementation.
Documentation:
- Remove bogus SME documentation concerning register state when
entering/exiting streaming mode.
Entry code:
- Switch over to the generic IRQ entry code (GENERIC_IRQ_ENTRY).
- Micro-optimise syscall entry path with a compiler branch hint.
Memory management:
- Enable huge mappings in vmalloc space even when kernel page-table
dumping is enabled.
- Tidy up the types used in our early MMU setup code.
- Rework rodata= for closer parity with the behaviour on x86.
- For CPUs implementing BBML2_NOABORT, utilise block mappings in the
linear map even when rodata= applies to virtual aliases.
- Don't re-allocate the virtual region between '_text' and '_stext',
as doing so confused tools parsing /proc/vmcore.
Miscellaneous:
- Clean-up Kconfig menuconfig text for architecture features.
- Avoid redundant bitmap_empty() during determination of supported
SME vector lengths.
- Re-enable warnings when building the 32-bit vDSO object.
- Avoid breaking our eggs at the wrong end.
Perf and PMUs:
- Support for v3 of the Hisilicon L3C PMU.
- Support for Hisilicon's MN and NoC PMUs.
- Support for Fujitsu's Uncore PMU.
- Support for SPE's extended event filtering feature.
- Preparatory work to enable data source filtering in SPE.
- Support for multiple lanes in the DWC PCIe PMU.
- Support for i.MX94 in the IMX DDR PMU driver.
- MAINTAINERS update (Thank you, Yicong).
- Minor driver fixes (PERF_IDX2OFF() overflow, CMN register offsets).
Selftests:
- Add basic LSFE check to the existing hwcaps test.
- Support nolibc in GCS tests.
- Extend SVE ptrace test to pass unsupported regsets and invalid vector
lengths.
- Minor cleanups (typos, cosmetic changes).
System registers:
- Fix ID_PFR1_EL1 definition.
- Fix incorrect signedness of some fields in ID_AA64MMFR4_EL1.
- Sync TCR_EL1 definition with the latest Arm ARM (L.b).
- Be stricter about the input fed into our AWK sysreg generator script.
- Typo fixes and removal of redundant definitions.
ACPI, EFI and PSCI:
- Decouple Arm's "Software Delegated Exception Interface" (SDEI)
support from the ACPI GHES code so that it can be used by platforms
booted with device-tree.
- Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
runtime calls.
- Fix a node refcount imbalance in the PSCI device-tree code.
CPU Features:
- Ensure register sanitisation is applied to fields in ID_AA64MMFR4.
- Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM guests
can reliably query the underlying CPU types from the VMM.
- Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
to our context-switching, signal handling and ptrace code.

"One notable addition is the creation of the 'transitional' keyword for
kconfig so CONFIG renaming can go more smoothly.
This has been a long-standing deficiency, and with the renaming of
CONFIG_CFI_CLANG to CONFIG_CFI (since GCC will soon have KCFI
support), this came up again.
The breadth of the diffstat is mainly this renaming.

Crypto library updates for 6.18
- Add a RISC-V optimized implementation of Poly1305. This code was
written by Andy Polyakov and contributed by Zhihang Shao.
- Migrate the MD5 code into lib/crypto/, and add KUnit tests for MD5.
Yes, it's still the 90s, and several kernel subsystems are still using
MD5 for legacy use cases. As long as that remains the case, it's
helpful to clean it up in the same way as I've been doing for other
algorithms. Later, I plan to convert most of these users of MD5 to use
the new MD5 library API instead of the generic crypto API.
- Simplify the organization of the ChaCha, Poly1305, BLAKE2s, and
Curve25519 code. Consolidate these into one module per algorithm,
and centralize the configuration and build process. This is the same
reorganization that has already been successful for SHA-1 and SHA-2.
- Remove the unused crypto_kpp API for Curve25519.
- Migrate the BLAKE2s and Curve25519 self-tests to KUnit.
- Always enable the architecture-optimized BLAKE2s code.
Due to interdependencies between test and non-test code, both are

Besides the new RISC-V code which is an addition, there are quite a
few simplifications due to the improved code organization for multiple
algorithms, the removal of the unused crypto_kpp API for Curve25519
and redundant tests, and the redesign of the BLAKE2s test.

Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux
Pull crypto library updates from Eric Biggers:
- Add a RISC-V optimized implementation of Poly1305. This code was
written by Andy Polyakov and contributed by Zhihang Shao.
- Migrate the MD5 code into lib/crypto/, and add KUnit tests for MD5.
Yes, it's still the 90s, and several kernel subsystems are still
using MD5 for legacy use cases. As long as that remains the case,
it's helpful to clean it up in the same way as I've been doing for
other algorithms.
Later, I plan to convert most of these users of MD5 to use the new
MD5 library API instead of the generic crypto API.
- Simplify the organization of the ChaCha, Poly1305, BLAKE2s, and
Curve25519 code.
Consolidate these into one module per algorithm, and centralize the
configuration and build process. This is the same reorganization that
has already been successful for SHA-1 and SHA-2.
- Remove the unused crypto_kpp API for Curve25519.
- Migrate the BLAKE2s and Curve25519 self-tests to KUnit.
- Always enable the architecture-optimized BLAKE2s code.

CRC updates for 6.18
Update crc_kunit to test the CRC functions in softirq and hardirq contexts, similar to what the lib/crypto/ KUnit tests do. Move the helper function needed to do this into a common header. This is useful mainly to test fallback code paths for when FPU/SIMD/vector registers are unusable. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCaNgevxQcZWJpZ2dlcnNA a2VybmVsLm9yZwAKCRDzXCl4vpKOK42cAP4qrRd2p4lLm4lntiL9igO0AVUl7Lsj 2hhYcVWNj24wwgD/bBb5aCCKfreOQbjMldYjL+UlRiYqQAsstlfcwY7EegM= =aEsr -----END PGP SIGNATURE----- Merge tag 'crc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux Pull CRC updates from Eric Biggers: "Update crc_kunit to test the CRC functions in softirq and hardirq contexts, similar to what the lib/crypto/ KUnit tests do.

dlm for 6.18
This set of patches add a dlm_release_lockspace() flag to request that node-failure recovery be performed for the node leaving the lockspace.

Merge tag 'hfs-v6.18-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/vdubeyko/hfs
Pull hfs updates from Viacheslav Dubeyko:
"This contains several fixes of syzbot reported issues, HFS/HFS+ fixes
of xfstests failures, and rework of HFS/HFS+ debug output subsystem.
- Kang Chen fixed a slab-out-of-bounds issue in hfsplus_uni2asc()
when hfsplus_uni2asc() is called from hfsplus_listxattr().
- Yang Chenzhi fixed a crash in hfsplus_bmap_alloc() if record offset
or length is larger than node_size.
- Yangtao Li corrected the error code from hfsplus_fill_super() if
Catalog File contains corrupted record for the case of hidden
directory's type.
- KMSAN uninit-value fixes: hfs_find_set_zero_bits() and
__hfsplus_ext_cache_extent() use kzalloc() instead of kmalloc(),
and in hfsplus_delete_cat() by proper initialization of struct
hfsplus_inode_info in the hfsplus_iget() logic.
- A slab-out-of-bounds issue could happen in hfsplus_strcasecmp() if
the length field of struct hfsplus_unistr is bigger than
HFSPLUS_MAX_STRLEN. Fixed by checking the length of comparing
strings, and if the strings' length is bigger than
HFSPLUS_MAX_STRLEN, then the length is corrected to this value.
- The generic/736 xfstest failed for HFS because the HFS volume
becomes corrupted after the test run.
The main reason was the absence of logic that corrects
mdb->drNxtCNID/HFS_SB(sb)->next_id (next unused CNID) after
deleting a record in Catalog File. That was fixed by implementing
the necessary logic in hfs_correct_next_unused_CNID()"

"This contains further preparatory changes for the asynchronous directory

- Add lookup_one_positive_killable() which allows overlayfs to
perform lookup that won't block on a fatal signal

only happen within a single mount
- Introduce kern_path_parent() for audit which sets the path to the
parent and returns a dentry for the target without holding any
locks on return

removal of an object from the filesystem:

kern_path_create() => start_creating_path()
user_path_create() => start_creating_user_path()
