fbdev: vga16fb: Drop unused assignment of platform_device_id driver data
The driver explicitly sets the .driver_data member of struct platform_device_id to zero without relying on that value. Drop these unused assignments. While touching this array unify spacing and usage of commas and use named initializers for .name.

Staging driver updates for 7.2-rc1
Here is the big set of staging driver updates for 7.2-rc1.
Nothing major in here, just constant grind of tiny cleanups and coding
style fixes and wrapper removals. Overall more code was removed than
added, always a nice sign that things are progressing forward.
Changes outside of drivers/staging/ was due to the octeon driver
changes, which for some reason also lives partially in the mips
subsystem, someday that all will be untangled and cleaned up, or just
removed entirely, it's hard to tell which is going to be its fate.
Other than octeon driver cleanups, in here are the usual:
- rtl8723bs driver reworking and cleanups, being the bulk of this
merge window given all of the issues and wrappers involved in that
beast of a driver.
- most driver cleanups
- sm750fb driver cleanups (which might be done, as this really should
be moved to the drm layer one of these days...)
- other tiny staging driver cleanups and fixes
All of these have been in linux-next for many weeks with no reported
issues.

SPDX patches for 7.2-rc1
Here is a "big" set of SPDX-like patches for 7.2-rc1. It is the addition of the ability for the kernel build process to generate a Software Bill of Materials (SBOM) in the SPDX format, that matches up exactly with just the files that are actually built for the specific kernel image generated. To generate a sbom, after the kernel has been built, just do: make sbom and marvel at the JSON file that is generated... This is needed by users for environments in which a SBOM is required (medical, automotive, anything shipped in the EU, etc.) and cuts down by a massive size the "naive" SBOM solution that many vendors have done by just including _all_ of the kernel files in the resulting document. This result is still a giant JSON file, that I am told parses properly, so we just have to trust that it is properly inclusive as attempting to parse that thing by hand is impossible. The scripts here are self-contained python scripts, no additional libraries or tools to create the SBOM are needed, which is important for many build systems. Overall it's just a bit over 4000 lines of "simple" python code, the most complex part is the regex matching lines, but those are nothing compared to what we maintain in scripts/checkpatch.pl today... The various parts where the tool touches the kbuild subsystem have been acked by the kbuild maintainer, so all should be good here. All of these patches have been in linux-next for weeks with no reported problems.

Merge tag 'slab-for-7.2-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull more slab updates from Vlastimil Babka:
- Introduce and wire up a new alloc_flags parameter for modifying
slab-specific behavior without adding or reusing gfp flags. Also
introduce slab_alloc_context to keep function parameter bloat in
check. Both are similar to what the page allocator does.
kmalloc_flags() exposes alloc_flags for mm-internal users.
- SLAB_ALLOC_NOLOCK flag is used to implement kmalloc_nolock()
behavior without relying on lack of __GFP_RECLAIM, which caused
false positives with workarounds like

lib: Add stale 'raid6' directory to .gitignore file
I keep having to do this, because people think they can just move
directories around and move the gitignore files around with them.
You really can't do that - the old generated files stay around for
others, and still need to be ignored in the old location.
So when moving gitignore entries around because you moved the files (or
when moving a whole gitignore file around because the directory it was
in moved), the old gitignore situation needs to be dealt with.
Yes, those files may have moved in *your* tree when you moved the
directory. And yes, new repositories will never even have seen them.
But all those other developers that see the result of your move still
likely have a working tree with the old state, and the files that were
hidden from git by an old gitignore file do not suddenly become
relevant.

NAND changes:
- Extend SPI NAND continuous read to Winbond devices, which requires
numerous changes in the spi-{mem,nand} layers such as the need for a
secondary read operation template.
- Continuous reads in general have also been enhanced/fixed for avoiding
potential issues at probe time and at block boundaries.
SPI NOR changes:
- Big set of cleanups and improvements to the locking support. This
series contains some cleanups and bug fixes for code and documentation
around write protection. Then support is added for complement locking,
which allows finer grained configuration of what is considered locked
and unlocked. Then complement locking is enabled on a bunch of Winbond
W25 flashes.
- Fix die erase support on Spansion flashes. Die erase is only supported
on multi-die flashes, but the die erase opcode was set for all. When
the opcode is set, it overrides the default chip erase opcode which
should be used for single-die flashes. Only set the opcode on
multi-die flashes. Also, the opcode was not set on multi-die s28hx-t
flashes. Set it so they can use die-erase correctly.
General changes:
- A few drivers and mappings have been removed following SoCs support
removal.
- And again, there is the usual load of misc improvements and fixes.

firewire updates for v7.2
This update includes the following changes. Unit drivers have been able to assign an arbitrary value in the mod_device entry, which is typed as kernel_ulong_t. While storing the pointer value is legitimate, conversion back to a pointer has been performed without preserving const qualifier. Uwe Kleine-König introduced an union to provide safer and more robust conversions, as part of the ongoing CHERI enhancement work for ARM and RISC-V architectures. This update includes changes in the sound subsystem, since the conversion pattern is widely used in ALSA firewire stack. The userspace applications can request the core function to perform isochronous resource management procedures. Dingsoul reported reference-count leak when these procedures are processed in workqueue contexts. This update refactors the relevant code paths following a divide and conquer approach. Consequently, it became clear that the issue still remain only in the path when userspace applications delegate automatic resource reallocation after bus resets to the core. In practice, the leak is rarely triggered, and a complete fix is still in progress. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQQE66IEYNDXNBPeGKSsLtaWM8LwEwUCajZH8gAKCRCsLtaWM8Lw E5zDAP4gyY1cTSdvIeKay8yYRLqZXtBQTzMeqfSsptLBQgemCAEAwAFP+KKghjU7 sDhDPgBD4bTDvYtjyh/RFb0lkTGV7wA= =3J0T -----END PGP SIGNATURE----- Merge tag 'firewire-updates-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire updates from Takashi Sakamoto: - firewire drivers have been able to assign an arbitrary value in the mod_device entry, which is typed as kernel_ulong_t.

SPI NOR changes for 7.2
Notable changes: - Big set of cleanups and improvements to the locking support. This series contains some cleanups and bug fixes for code and documentation around write protection. Then support is added for complement locking, which allows finer grained configuration of what is considered locked and unlocked. Then complement locking is enabled on a bunch of Winbond W25 flashes. - Fix die erase support on Spansion flashes. Die erase is only supported on multi-die flashes, but the die erase opcode was set for all. When the opcode is set, it overrides the default chip erase opcode which should be used for single-die flashes. Only set the opcode on multi-die flashes. Also, the opcode was not set on multi-die s28hx-t flashes. Set it so they can use die-erase correctly. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQQTlUWNzXGEo3bFmyIR4drqP028CQUCajKB6hQccHJhdHl1c2hA a2VybmVsLm9yZwAKCRAR4drqP028Ca/wAQCL6gEVL6OXpBrHRxmwt5l8/m7h9ZML fYf15pwRE2fg5gD+NSavIqhuSp9yAF1PhNTAirE0iKDTo7t12Z9HM8LYGQ4= =w7Eg -----END PGP SIGNATURE----- Merge tag 'spi-nor/for-7.2' into mtd/next SPI NOR changes for 7.2 Notable changes: - Big set of cleanups and improvements to the locking support.

9p: skip nlink update in cacheless mode to fix WARN_ON
v9fs_dec_count() unconditionally calls drop_nlink() on regular files,
even when the inode's nlink is already zero. In cacheless mode the
client refetches inode metadata from the server (the source of truth)
on every operation, so by the time v9fs_remove() returns, the locally
cached nlink may already reflect the post-unlink value:
1. Client initiates unlink, server processes it and sets nlink to 0
2. Client refetches inode metadata (nlink=0) before unlink returns
3. Client's v9fs_remove() completes successfully
4. Client calls v9fs_dec_count() which calls drop_nlink() on nlink=0
This race is easily triggered under heavy unlink workloads, such as
stress-ng's unlink stressor, producing the following warning:
WARNING: fs/inode.c:417 at drop_nlink+0x4c/0xc8
Call trace:
drop_nlink+0x4c/0xc8
v9fs_remove+0x1e0/0x250 [9p]
v9fs_vfs_unlink+0x20/0x38 [9p]
vfs_unlink+0x13c/0x258
...
In cacheless mode the server is authoritative and the inode is on its
way out, so locally adjusting nlink buys nothing. Skip v9fs_dec_count()
entirely when neither CACHE_META nor CACHE_LOOSE is set, which both
avoids the warning and removes a class of nlink races (two concurrent
unlinkers observing nlink > 0 and both calling drop_nlink()) that an
nlink == 0 guard alone would only narrow rather than close.

net/9p: fix race condition on rdma->state in trans_rdma.c
The rdma->state field is modified without holding req_lock in both
recv_done() and p9_cm_event_handler(), while rdma_request() accesses
the same field under the req_lock spinlock. This inconsistent locking
creates a race condition:
- recv_done() running in softirq completion context sets
rdma->state = P9_RDMA_FLUSHING without acquiring req_lock
- p9_cm_event_handler() modifies rdma->state at multiple points
(ADDR_RESOLVED, ROUTE_RESOLVED, ESTABLISHED, CLOSED) without
req_lock
- rdma_request() uses spin_lock_irqsave(&rdma->req_lock, flags) to
protect the read-modify-write of rdma->state
The race can cause lost state transitions: recv_done() or the CM
event handler could set state to FLUSHING/CLOSED while rdma_request()
is concurrently checking or modifying state under the lock, leading to
the FLUSHING transition being silently overwritten by CLOSING. This
corrupts the connection state machine and can cause use-after-free on
RDMA request objects during teardown.
Fix by adding req_lock protection to all rdma->state modifications in
recv_done() and p9_cm_event_handler(), matching the pattern already
used in rdma_request(). Use spin_lock_irqsave/spin_unlock_irqrestore
in the CM event handler since it can race with recv_done() which runs
in softirq context.
Tested with a kernel module that races two threads (simulating
rdma_request and recv_done/CM handler) on rdma->state with proper
locking: 5.5M+ FLUSHING writes over 27M iterations with 0 lost
transitions.

9p: Enable symlink caching in page cache
Currently, when cache=loose is enabled, file reads are cached in the page cache, but symlink reads are not. This patch allows the results of p9_client_readlink() to be stored in the page cache, eliminating the need for repeated 9P transactions on subsequent symlink accesses. This change improves performance for workloads that involve frequent symlink resolution.

9p: Add mount option for negative dentry cache retention
Introduce a new mount option, negtimeout, for v9fs that allows users to specify how long negative dentries are retained in the cache. The retention time can be set in milliseconds (e.g. negtimeout=10000 for a 10secs retention time) or a negative value (e.g. negtimeout=-1) to keep negative entries until the buffer cache management removes them. For consistency reasons, this option should only be used in exclusive or read-only mount scenarios, aligning with the cache=loose usage.

Not caching negative dentries can result in poor performance for workloads that repeatedly look up non-existent paths. Each such lookup triggers a full 9P transaction with the server, adding unnecessary overhead. A typical example is source compilation, where multiple cc1 processes are spawned and repeatedly search for the same missing header files over and over again. This change enables caching of negative dentries, so that lookups for known non-existent paths do not require a full 9P transaction. The cached negative dentries are retained for a configurable duration (expressed in milliseconds), as specified by the ndentry_timeout field in struct v9fs_session_info. If set to -1, negative dentries are cached indefinitely. This optimization reduces lookup overhead and improves performance for workloads involving frequent access to non-existent paths.

9p: avoid returning ERR_PTR(0) from mkdir operations
When mkdir succeeds, v9fs_vfs_mkdir_dotl() and v9fs_vfs_mkdir() return
ERR_PTR(0) which is incorrect. They should return NULL instead for
success and ERR_PTR() only with negative error codes for failure.
Return NULL instead of passing to ERR_PTR while err is zero
Fixes smatch warnings:
fs/9p/vfs_inode_dotl.c:420 v9fs_vfs_mkdir_dotl() warn: passing zero to 'ERR_PTR'
fs/9p/vfs_inode.c:695 v9fs_vfs_mkdir() warn: passing zero to 'ERR_PTR'
The v9fs_vfs_mkdir() code was further simplified because v9fs_create()
can never return NULL, so we do not need to check for fid being set
separately, and the error path can be a simple return immediately after
v9fs_create() failure.
There is no intended functional change.

9p: avoid putting oldfid in p9_client_walk() error path
When p9_client_walk() is called with clone set to false, fid aliases
oldfid. If the walk subsequently fails after the request has been sent,
the error path jumps to clunk_fid, which currently calls p9_fid_put(fid)
unconditionally.
This drops a reference to oldfid even though ownership of oldfid remains
with the caller. If this is the last reference, oldfid can be clunked and
destroyed while the caller still expects it to be valid. A later use or
put of oldfid can then trigger a use-after-free or refcount underflow.
Fix this by only putting fid in the clunk_fid error path when it does not
alias oldfid, matching the existing guard in the error path below.
This can be triggered when a multi-component walk is split into multiple
p9_client_walk() calls and a later non-cloning walk fails. A reproducer
and refcount warning logs are available on request.

validation for attributes, attribute lists, index roots and entries,
EA entries, mapping pairs, and $LogFile restart areas. These changes
fix several out-of-bounds access, integer overflow, and inconsistent
metadata handling issues.
- Preventing a writeback deadlock involving extent MFT records
- Fixing resource leaks in fill_super() failure paths and the name cache
- Serializing volume label access and improving its error handling
- Fixing mapping-pairs decoding bounds and LCN overflow checks
- Keeping resident index root metadata consistent during resize
- Fixing the reported size of symbolic links
- Avoiding an unnecessary allocation for resident inline data
- Adds support for following and creating Windows native symbolic links.
Relative links, absolute links, and junctions are handled, with new
mount options controlling native symlink creation and absolute target
translation. The existing WSL symlink behavior remains the default.
- The unsupported quota code is removed, along with several smaller
cleanups.

IMA and EVM still calculate the file data/metadata hashes respectively. - Introduce support for removing IMA measurement list records stored in kernel memory The IMA measurement list can grow large depending on policy, but removing records breaks remote attestation, unless they are safely preserved and made available for attestation requests. Until environments are prepared to preserve the measurement records, a new CONFIG_IMA_STAGING Kconfig option is introduced to guard against deletion. Several approaches for removing measurement list records were evaluated but rejected due to filesystem constraints, the introduction of a new critical data record, and locking concerns. Two methods are being upstreamed: staged deletion with confirmation, and staged deletion of N records without confirmation. Both methods minimize the period during which new measurements are blocked from being appended to the measurement list by staging the measurement list. A comparison of the two methods is included in the documentation. - Some code cleanup, and a couple of bug fixes * tag 'integrity-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: doc: security: Add documentation of exporting and deleting IMA measurements ima: Support staging and deleting N measurements records ima: Add support for flushing the hash table when staging measurements ima: Add support for staging measurements with prompt ima: Introduce ima_dump_measurement() ima: Use snprintf() in create_securityfs_measurement_lists ima: Mediate open/release method of the measurements list ima: Introduce _ima_measurements_start() and _ima_measurements_next() ima: Introduce per binary measurements list type binary_runtime_size value ima: Introduce per binary measurements list type ima_num_records counter ima: Replace static htable queue with dynamically allocated array ima: Remove ima_h_table structure evm: terminate and bound the evm_xattrs read buffer integrity: Add support for sigv3 verification using ML-DSA keys integrity: Refactor asymmetric_verify for reusability integrity: Check that algo parameter is within valid range integrity: Check for NULL returned by asymmetric_key_public_key ima: return error early if file xattr cannot be changed ima: Fix sigv3 signature handling for EVM_IMA_XATTR_DIGSIG |

- The 2 patch series "selftests/mm: clean up build output and verbosity"
from Li Wang removes some noise from the MM selftests build out.
- The 3 patch series "mm: Free contiguous order-0 pages efficiently"
from Ryan Roberts speeds up the freeing of a batch of 0-order pages by
first scanning them for coalescing opportunities. This is applicable to
vfree() and to the releasing of frozen pages.
- The 11 patch series "mm/damon: introduce DAMOS failed region quota
charge ratio" from SeongJae Park addresses a DAMOS usability issue: The
DAMOS quota often exhausts prematurely because it charges for all memory
attempted, causing slow and inconsistent performance when actions fail
on unreclaimable memory.
To fix this, a new feature lets users set a smaller, flexible quota
charge ratio (via a numerator and denominator) for failed regions.
Since failed actions cause less overhead, reducing their quota cost
ensures more predictable and efficient DAMOS processing

reclaim loop and dirty writeback handling. Large performance
improvements are measured.
- The 3 patch series "use vma locks for proc/pid/{smaps|numa_maps}

force_thp_readahead gate to support mappings with any usefully large
maximum folio order under the cache cap.
- The 6 patch series "userfaultfd/pagemap: pre-existing fixes" from
Kiryl Shutsemau fixes a bunch of minor issues in the

charge ratio (via a numerator and denominator) for failed regions.
Since failed actions cause less overhead, reducing their quota cost
ensures more predictable and efficient DAMOS processing

Arm:
"This is a bit of an odd merge window on the KVM/arm64 front. There is
absolutely no new feature in the pull request. It is purely fixes,
because it is simply becoming too hard to review new stuff when so
many AI-fuelled fixes hit the list".
- Significant cleanup of the vgic-v5 PPI support which was merged in
7.1. This makes the code more maintainable, and squashes a couple
of bugs in the meantime.
- Set of fixes for the handling of the MMU in an NV context,
particularly VNCR-triggered faults. S1POE support is fixed
as well.
- Large set of pKVM fixes, mostly addressing recurring issues
around hypervisor tracking of donated pages in obscure cases
where the donation could fail and leave things in a bizarre
state.
- Fixes for the so-called "lazy vgic init", which resulted in
sleeping operations in non-preemptible sections. This turned
out to be far more invasive than initially expected...
- Reduce the overhead of L1/L2 context switch by not touching
the FP registers.
- Fix the way non-implemented page sizes are dealt with when
a guest insist on using them for S2 translation.
- The usual set of low-impact fixes and cleanups all over the map.
Loongarch:
- On a request for lazy FPU load, load all FPU state that the VM
supports instead of enabling only the part (FPU, LSX or LASX)
that caused the FPU load request.
- Some enhancements about interrupt injection.
- Some bug fixes and other small changes.
RISC-V:
- Batch G-stage TLB flushes for GPA range based page table updates
- Convert HGEI line management to fully per-HART
- Fix missing CSR dirty marking when FWFT state updated via ONE_REG
- Fix stale FWFT feature exposure to Guest/VM
- Speed up dirty logging write faults using MMU rwlock and atomic
PTE updates using cmpxchg() for permission-only changes
- Use flexible array for APLIC IRQ state
- Use kvm_slot_dirty_track_enabled() for logging enable check on
a memslot
- Avoid skipping valid pages in kvm_riscv_gstage_wp_range()
- Avoid skipping valid pages in kvm_riscv_gstage_unmap_range()
- Use endian-specific __lelong for NACL shared memory
S390:
- KVM_PRE_FAULT_MEMORY support
- Support for 2G hugepages
- Support for the ASTFLEIE 2 facility
- Support for fast inject using kvm_arch_set_irq_inatomic
- Fix potential leak of uninitialized bytes
- A few more misc gmap fixes.
x86:
- Generic support for the more granular permissions allowed by EPT,
namely "read" (which was previously usurping the U bit) and
separate execution bits for kernel and userspace.
- Do not assume that all page tables start with U=1/W=1/NX=0 at the
root, as AMD GMET needs to have U=0 at the root.
- Introduce common assembly macros for use within Intel and AMD
vendor-specific vmentry code. This touches the SPEC_CTRL handling,
which is now entirely done in assembly for Intel (by reusing the
AMD code that already existed), and register save/restore which
uses some macro magic to compute the offsets in the struct. Both
of these are preparatory changes for upcoming APX support.
- Clean up KVM's register tracking and storage, primarily to prepare for
APX support, which expands the maximum number of GPRs from 16 to 32.
- Keep a single copy of the PDPTRs rather than two, since architecturally
there is just one.
- Handle EXIT_FASTPATH_EXIT_USERSPACE in vendor code to ensure vendor code
gets a chance to handle things like reaping the PML buffer.
- Update KVM's view of PV async enabling if and only if the MSR write fully
succeeds.
- Fix a variety of issues where the emulator doesn't honor guest-debug state,
and clean up related code along the way.
- Synthesize EPT Violation and #NPF "error code" bits when injecting faults
into L1 that didn't originate in hardware (in which case the VMCS/VMCB
doesn't hold relevant information).
- Add support for virtualizing (well, emulating) AMD's flavor of CPL>0 CPUID
faulting.
- Clean up the GPR APIs so that KVM's use of "raw" is consistent, and fix a
variety of minor bugs along the way.
- Fix an OOB memory access due to not checking the VP ID when handling a
Hyper-V PV TLB flush for L2.
- Fix a bug in the mediated PMU's handling of fixed counters that allowed the
guest to bypass the PMU event filter.
- Allow userspace to return EAGAIN when handling SNP and TDX hypercalls, so
the KVM can forward a "retry" status code to the guest, and reserve all
unused error codes for future usage.
- Overhaul the TDP MMU => S-EPT code to move as much S-EPT specific logic as
possible into the TDX code, and to funnel (almost) all S-EPT updates into
a single chokepoint. The motivation is largely to prepare for upcoming
Dynamic PAMT support, but the cleanups are nice to have on their own.
- Plug a hole in shadow page table handling, where KVM fails to recursively
zap nested EPT/NPT shadow page tables when the nested hypervisor tears
down its own EPT/NPT page tables from the bottom up
x86 (Intel):
- Support for nested MBEC (Mode-Based Execute Control), see above in the
generic section; also run with MBEC enabled even for non-nested mode.
- Use the kernel's "enum pg_level" in the TDX APIs instead of the TDX-Module's
level definitions (which are 0-based).
- Rework the TDX memory APIs to not require/assume that guest memory is
backed by "struct page" (in prepartion for guest_memfd hugepage support).
- Fix a largely benign bug where KVM TDX would incorrectly state it could
emulate several x2APIC MSRs.
- Use the "safe" WRMSR API when proxying LBR MSR writes as the to-be-written
value is guest controlled and completely unvalidated.
x86 (AMD):
- Support for nested GMET (Guest Mode Execution Trap), see above in the
generic section; also run with GMET enabled even for non-nested mode.
- Fixes and minor cleanups to GHCB handling, on top of the earlier work
already merged into 7.1-rc.
- Ensure KVM's copy of CR0 and CR3 are up-to-date prior to invoking
fastpath handlers.
- Add support for virtualizing gPAT (KVM previously just used L1's PAT when
running L2).
- Fix goofs where KVM mishandles side effects (e.g. single-step and PMC
updates) when emulating VMRUN.
- Fix a variety of bugs in AVIC's handling of x2APIC MSR interception, most
notably where KVM didn't disable interception of IRR, ISR, and TMR regs.
- Add support for virtualizing Host-Only/Guest-Only bits in the mediated PMU.
- Don't advertise support for unusable VM types, and account for VM types
that are disabled by firmware, e.g. to mitigate security vulnerabilities.
- Rewrite the SEV {en,de}crypt debug ioctls as they were riddle with bugs and
unnecessarily complicated, and add comprehensive tests.
- Clean up and deduplicate the SEV page pinning code.
- Fix minor goofs related to writing back CPUID information after firmware
rejects a CPUID page for an SNP vCPU.
Generic:
- Rename invalidate_begin() to invalidate_start() throughout KVM to follow
the kernel's nomenclature, e.g. for mmu_notifiers.
- Use guard() to cleanup up various KVM+VFIO flows.
- Minor cleanups.
guest_memfd:
- Return -EEXIST instead of -EINVAL if userspace attempts to bind a gmem
range to multiple memslots, and fix the test that was supposed to ensure
KVM returns -EEXIST.
- Treat memslot binding offsets and sizes as unsigned values to fix a bug
where KVM interprets a large "offset + size" as a negative value and allows
a nonsensical offset.
- Use the inode number instead of the page offset for the NUMA interleaving
index to fix a bug where the effective index would jump by two for
consecutive pages (the caller also adds in the page offset).
Selftests:
- Randomize the dirty log test's delay when reaping the bitmap on the first
pass, as always waiting only 1ms hid a KVM RISC-V bug as the test reaped the
bitmap before KVM could build up enough state to hit the bug.
- A pile of one-off fixes and cleanups.

caused the FPU load request
- Some enhancements about interrupt injection
- Some bug fixes and other small changes
RISC-V:
- Batch G-stage TLB flushes for GPA range based page table updates
- Convert HGEI line management to fully per-HART
- Fix missing CSR dirty marking when FWFT state updated via ONE_REG
- Fix stale FWFT feature exposure to Guest/VM
- Speed up dirty logging write faults using MMU rwlock and atomic PTE
updates using cmpxchg() for permission-only changes
- Use flexible array for APLIC IRQ state
- Use kvm_slot_dirty_track_enabled() for logging enable check on a
memslot
- Avoid skipping valid pages in kvm_riscv_gstage_wp_range()
- Avoid skipping valid pages in kvm_riscv_gstage_unmap_range()
- Use endian-specific __lelong for NACL shared memory
S390:
- KVM_PRE_FAULT_MEMORY support
- Support for 2G hugepages
- Support for the ASTFLEIE 2 facility
- Support for fast inject using kvm_arch_set_irq_inatomic
- Fix potential leak of uninitialized bytes
- A few more misc gmap fixes
x86:
- Generic support for the more granular permissions allowed by EPT,
namely "read" (which was previously usurping the U bit) and
separate execution bits for kernel and userspace
- Do not assume that all page tables start with U=1/W=1/NX=0 at the
root, as AMD GMET needs to have U=0 at the root
- Introduce common assembly macros for use within Intel and AMD
vendor-specific vmentry code. This touches the SPEC_CTRL handling,
which is now entirely done in assembly for Intel (by reusing the
AMD code that already existed), and register save/restore which
uses some macro magic to compute the offsets in the struct. Both of
these are preparatory changes for upcoming APX support
- Clean up KVM's register tracking and storage, primarily to prepare
for APX support, which expands the maximum number of GPRs from 16
to 32
- Keep a single copy of the PDPTRs rather than two, since
architecturally there is just one
- Handle EXIT_FASTPATH_EXIT_USERSPACE in vendor code to ensure vendor
code gets a chance to handle things like reaping the PML buffer
- Update KVM's view of PV async enabling if and only if the MSR write
fully succeeds
- Fix a variety of issues where the emulator doesn't honor
guest-debug state, and clean up related code along the way
- Synthesize EPT Violation and #NPF "error code" bits when injecting
faults into L1 that didn't originate in hardware (in which case the
VMCS/VMCB doesn't hold relevant information)
- Add support for virtualizing (well, emulating) AMD's flavor of
CPL>0 CPUID faulting
- Clean up the GPR APIs so that KVM's use of "raw" is consistent, and
fix a variety of minor bugs along the way
- Fix an OOB memory access due to not checking the VP ID when
handling a Hyper-V PV TLB flush for L2
- Fix a bug in the mediated PMU's handling of fixed counters that
allowed the guest to bypass the PMU event filter
- Allow userspace to return EAGAIN when handling SNP and TDX
hypercalls, so the KVM can forward a "retry" status code to the
guest, and reserve all unused error codes for future usage
- Overhaul the TDP MMU => S-EPT code to move as much S-EPT specific
logic as possible into the TDX code, and to funnel (almost) all
S-EPT updates into a single chokepoint. The motivation is largely
to prepare for upcoming Dynamic PAMT support, but the cleanups are
nice to have on their own
- Plug a hole in shadow page table handling, where KVM fails to
recursively zap nested EPT/NPT shadow page tables when the nested
hypervisor tears down its own EPT/NPT page tables from the bottom
up
x86 (Intel):
- Support for nested MBEC (Mode-Based Execute Control), see above in
the generic section; also run with MBEC enabled even for non-nested
mode
- Use the kernel's "enum pg_level" in the TDX APIs instead of the
TDX-Module's level definitions (which are 0-based)
- Rework the TDX memory APIs to not require/assume that guest memory
is backed by "struct page" (in prepartion for guest_memfd hugepage
support)
- Fix a largely benign bug where KVM TDX would incorrectly state it
could emulate several x2APIC MSRs
- Use the "safe" WRMSR API when proxying LBR MSR writes as the
to-be-written value is guest controlled and completely unvalidated
x86 (AMD):
- Support for nested GMET (Guest Mode Execution Trap), see above in
the generic section; also run with GMET enabled even for non-nested
mode
- Fixes and minor cleanups to GHCB handling, on top of the earlier
work already merged into 7.1-rc
- Ensure KVM's copy of CR0 and CR3 are up-to-date prior to invoking
fastpath handlers
- Add support for virtualizing gPAT (KVM previously just used L1's
PAT when running L2)
- Fix goofs where KVM mishandles side effects (e.g. single-step and
PMC updates) when emulating VMRUN
- Fix a variety of bugs in AVIC's handling of x2APIC MSR
interception, most notably where KVM didn't disable interception of
IRR, ISR, and TMR regs
- Add support for virtualizing Host-Only/Guest-Only bits in the
mediated PMU
- Don't advertise support for unusable VM types, and account for VM
types that are disabled by firmware, e.g. to mitigate security
vulnerabilities
- Rewrite the SEV {en,de}crypt debug ioctls as they were riddle with
bugs and unnecessarily complicated, and add comprehensive tests
- Clean up and deduplicate the SEV page pinning code
- Fix minor goofs related to writing back CPUID information after
firmware rejects a CPUID page for an SNP vCPU
Generic:
- Rename invalidate_begin() to invalidate_start() throughout KVM to
follow the kernel's nomenclature, e.g. for mmu_notifiers
- Use guard() to cleanup up various KVM+VFIO flows
- Minor cleanups
guest_memfd:
- Return -EEXIST instead of -EINVAL if userspace attempts to bind a
gmem range to multiple memslots, and fix the test that was supposed
to ensure KVM returns -EEXIST
- Treat memslot binding offsets and sizes as unsigned values to fix a
bug where KVM interprets a large "offset + size" as a negative
value and allows a nonsensical offset
- Use the inode number instead of the page offset for the NUMA
interleaving index to fix a bug where the effective index would
jump by two for consecutive pages (the caller also adds in the page
offset)
Selftests:
- Randomize the dirty log test's delay when reaping the bitmap on the
first pass, as always waiting only 1ms hid a KVM RISC-V bug as the
test reaped the bitmap before KVM could build up enough state to
hit the bug
- A pile of one-off fixes and cleanups"

RISC-V updates for v7.2
- Prevent get_free_mem_region() from returning regions that are
unmappable in certain circumstances by defining
DIRECT_MAP_PHYSMEM_END for RISC-V
- Fix an early boot problem with kexec_file when the amount of
installed physical memory installed on the system exceeds the direct
map size, which is possible in certain RISC-V virtual memory modes
- Unconditionally sfence.vma in the new vmalloc area handling code in
the page fault handler, since even the presence of Svvptc doesn't
guarantee that the CPU won't immediately fault again after the
exception handler completes and subsequently crash
- Fix ftrace_graph_ret_addr() to use the correct task pointer
(aligning with what other architectures do)
- Fix the misaligned access performance checking code in cases when
performance is specified on the kernel command line and when CPUs
have been brought offline and back online
- Get rid of a bogus address offset in the non-frame-pointer version
of walk_stackframe(), aligning it with the frame pointer-based code
- Fix a RISC-V kfence issue causing bogus use-after-free warnings
- Add ARCH_HAS_CC_CAN_LINK for RISC-V, which needs different compiler
command line flags than other architectures
- Implement _THIS_IP_ using RISC-V-specific assembly, which seems to
be less brittle (from a compiler point of view) than taking the
address of a label
- Reduce kernel startup overhead by defining
HAVE_BUILDTIME_MCOUNT_SORT, since arch/riscv meets all the
requirements
- Patch the CFI vDSO during alternatives processing, not only the
standard vDSO
- Fix a potential memory leak in the cacheinfo code
- Clean up kernel/setup.c:add_resource() to pass along the return
value from insert_resource() and to improve the display of
resource ranges
- Clean up our purgatory.[ch] by aligning our purgatory() prototype
to what's in arch/x86, and by cleaning up verify_sha256_digest()
- Clean up cpu_is_stopped() to align its function a little more
closely to its name
- Replace some unbounded string function usage in get_early_cmdline()
and the ptdump code with strscpy()
- Replace sprintf() with sysfs_emit() in cpu_show_ghostwrite() for
safer bounds checking
- Standardize how compiler output flags are specified in the RISC-V

- Use the Linux-generic cmp_int() macro in place of an open-coded

ring-buffer: Updates for v7.2:
- Do not invalidate entire buffer for invalid sub-buffers For the persistent ring buffer, if one sub-buffer is found to be invalid, it invalidates the entire per CPU ring buffer. This can lose a lot of valuable data if there's some corruption with the writes to the buffer not syncing properly on a hard crash. Instead, if a sub-buffer is found to be invalid, simply zero it out and mark it for "missed events". When the persistent ring buffer is read and a sub-buffer that was cleared due to being invalid on boot up is discovered, the output will show "[LOST EVENTS]" to let the user know that events were missing at that location. Displaying the events from valid buffers can still be useful. - Add a test to be able to test corrupted sub-buffers If a persistent ring buffer is created as "ptraingtest" and the new config that adds the test is enabled, when a panic happens, the kernel will randomly corrupt one of the per CPU ring buffers.

This can lose a lot of valuable data if there's some corruption with the writes to the buffer not syncing properly on a hard crash. Instead, if a sub-buffer is found to be invalid, simply zero it out and mark it for "missed events". When the persistent ring buffer is read and a sub-buffer that was cleared due to being invalid on boot up is discovered, the output will show "[LOST EVENTS]" to let the user know that events were missing at that location. Displaying the events from valid buffers can still be useful. - Add a test to be able to test corrupted sub-buffers If a persistent ring buffer is created as "ptraingtest" and the new config that adds the test is enabled, when a panic happens, the kernel will randomly corrupt one of the per CPU ring buffers. On boot up, the sub-buffers with the corruption should be cleared and flagged. When reading this buffer, the missed events should should [LOST EVENTS]. - Add commit number in the sub-buffer meta debug info The commit is used to know the content of a meta page. Add it to the buffer_meta file that is shown for each per CPU buffer. - Clean up the persistent ring buffer validation code Add some helper functions and make variable names more consistent. * tag 'trace-ring-buffer-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Better comment the use of RB_MISSED_EVENTS ring-buffer: Show persistent buffer dropped events in trace_pipe file ring-buffer: Show persistent buffer dropped events in trace file ring-buffer: Have dropped subbuffers be persistent across reboots ring-buffer: Cleanup buffer_data_page related code ring-buffer: Cleanup persistent ring buffer validation ring-buffer: Show commit numbers in buffer_meta file ring-buffer: Add persistent ring buffer invalid-page inject test ring-buffer: Skip invalid sub-buffers when rewinding persistent ring buffer ring-buffer: Skip invalid sub-buffers when validating persistent ring buffer |
