Pull sh updates from John Paul Adrian Glaubitz:
"Fixes and improvements for various boards as well as the generic sh
kernel:
- help the mach-x3proto and ecovec24 boards get rid off the use of
the old platform data API in the kernel. For the former board,
software nodes are being used for gpio-keys now while for the
latter board, static device properties are used to describe the
touchscreen (Dmitry Torokhov)
- a build fix when CONFIG_BUILTIN_DTB is enabled, and fix an issue
with __get_user_u64() and __put_user_u64() using wrong memory
operands which could cause the kernel build to fail with "invalid
'asm'" or an internal compiler error in GCC's change_address_1
(Florian Fuchs)
- update various default configuration files of several boards to
replace the removed CONFIG_USB_GADGET_M66592 with the new
CONFIG_USB_M66592 Kconfig option (Pengpeng Hou)
- fix two issues with the SH-7785LCR evaluation board: fix a kernel
memory leak which occurred as a result of the prio and sense lists
being sorted too early in register_intc_controller(), and fix the
the registration of the PCA9564 controller so that the RTC works
properly again (Karl Mehltretter)
- fix missing cookies when calling free_irq() in the maple bus driver
which ensures that IRQ handlers can be properly unregistered and
the kernel does not emit a WARN message (Runyu Xiao)
- select BINFMT_FLAT_NO_DATA_START_OFFSET for !MMU configurations
such that there is no gap at the end of text and init runs which
causes the GOT register to point below the real GOT, so every GOT
load reads the neighbouring slot and gets a wrong pointer (Waldemar
Brodkorb)"

Pull ext4 updates from Ted Ts'o:
"Add support for buffered iomap support in ext4. This is not enabled by
default, but requires the buffered_iomap mount option, as this mode
does not support online defragmentation, inline data, fsverify,
fscrypt, non-extent inodes, and data=journal mode. If buffered_iomap
is enabled, ext4 will fall back to the original I/O code path
automatically if necessary. Large writes show significant performance
improvements when buffered iomap is enabled.
There are also miscellaneous bug fixes and improvements, including for
fast commit and avoiding deadlocks and out-of-bound reads when
handling corner cases involving corrupted file systems"

git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs
Pull ntfs updates from Namjae Jeon:
"New features:
- Implement ioctls to list, read, write, and remove named streams on
files and directories. Provide optional file:stream pathname access
through streams_interface=windows, exposing streams as regular file
descriptors with support for mmap, locking, truncation, and
allocation.
- Support file attribute queries and updates through FS_IOC_GETFLAGS
and FS_IOC_SETFLAGS. Store immutable, append-only, nodump, and
noatime settings in the private $LINUXFLAGS extended attribute and
restore them when loading inodes. Also report compression,
encryption, and the mount-wide case-folding policy as read-only
attributes.
Other changes:
- Expose the existing NTFS volume serial number through FS_IOC_GETFSUUID
by registering it as an eight-byte filesystem identifier.
- Validate MFT I/O geometry and write MFT records and mirror data
through mapped I/O units, keeping neighboring records intact when
multiple records share a native 4Kn block. Track folio writeback
until all BIOs complete, serialize raw record updates against
writeback, and use the caller's requested completion mode.
- Discard stale uninitialized cache data before extending initialized
size, ensure shared mmap writes update initialized size after
native 4Kn size extension, and synchronize attribute inode sizes
after internal resizes. Keep VFS and NTFS sizes consistent when
write-error rollback fails and record the volume error.
- Wait for existing folio writeback before updating attribute data,
require page alignment for full-page write optimizations, and
include the final partial cluster in synchronous writes. Skip
duplicate VFS page-cache truncation under the MFT record lock to
avoid a truncate and writeback deadlock.
- Restart allocation zone searches after failed hints and prevent
contiguous allocation requests from returning additional disjoint
runs that callers leave uninitialized. Allow fallocate after
MFT-zone exhaustion and interrupt allocation loops only for fatal
signals, avoiding spurious interruptions from io_uring task-work
notifications.
- Wait for the initial bitmap scan before extending the MFT bitmap,
bound direct allocation candidates by the volume size, update
free-space accounting, and undo only newly allocated clusters after
run coalescing. Update attribute-list inode size before reserving
additional space.
- Hold runlist locks while expanding non-resident attributes, balance
locks during MFT extension error handling, and avoid pointers
invalidated by runlist reallocation. Keep source runlists available
for rollback and allocate enough room for runlist markers and
terminators.
- Return errors for unmappable runlist fragments instead of treating
them as holes or delayed allocation. Check non-resident attribute
sizes against their allocation and fail mounts when $MFT needs
extent records outside the decoded runlist to describe itself,
preventing silent zero reads and mount hangs.
- Load and validate $BadClus:$Bad at mount time and reserve known bad
clusters before the free-space scan. Fall back to read-only
operation when bad-cluster metadata cannot be validated and prevent
subsequent read-write remounts.
- Serialize volume flag updates and retain the dirty bit after
metadata changes while the volume remains mounted read-write.
Persist recorded errors after final metadata commits, fail ordinary
read-only remounts on sync, commit, or flush errors, and retain the
dirty bit on forced remounts.
- Flush the device write cache when syncing directories and report
flush failures from both file and directory fsync. Drain in-flight
direct I/O before buffered write fallback and keep nonblocking
requests from entering the blocking fallback path.
- Mount hibernated volumes, or volumes whose hibernation state cannot
be determined, read-only regardless of the errors= policy. Prevent
mount-time and dirty-state updates from modifying hibernated
volumes.
- Validate complete EA chains, link zero-terminated tails when
appending entries, retain the EA presence flag, and distinguish
empty values from removal. Propagate lookup, write, and truncate
errors, restore both EA attributes after failed updates, and shut
down the volume if restoration fails.
- Restore the previous ACL xattr when a subsequent WSL mode update
fails, including replacement and removal cases. Record rollback
failures so an unsuccessful permission change cannot silently leave
inconsistent ACL and mode state.
- Apply MST fixups to individual index blocks on large-page systems
and use fixed 512-byte VCN units when an index block is smaller
than its cluster. Support lookup and removal of POSIX names
containing Windows-invalid characters and identify directory
symlinks and junctions during enumeration.
- Report the stored creation time for symbolic links through statx()
when querying the link itself with AT_SYMLINK_NOFOLLOW.
- Use wider decompression offsets to avoid overflow on 64 KB pages,
accept the standard sparse compression unit, and require the
compressed-size field only on the first attribute extent. Block
direct reads and skip readahead for encrypted files to prevent
returning raw ciphertext.
- Validate index entry offsets, logfile update sequence array counts,
attribute-list sizes, and index collation key lengths to prevent
out-of-bounds accesses, NULL pointer dereferences, and excessive
allocations from corrupt volume metadata.
- Derive FITRIM bitmap indexes from the page size and retain the full
64-bit minimum discard length. Balance highmem mappings in logfile
and MFT mirror checks and propagate specific errors from extent,
attribute, and reparse operations.
- Compare streams_interface with the mounted volume's setting during
remount, make named-stream UAPI padding explicit, document stream
access and Linux file attributes, and add the NTFS UAPI header to
MAINTAINERS"

git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/exfat
Pull exfat updates from Namjae Jeon:
- Use the recalculated append position when advancing valid_size, dirty
all pages involved in valid-data extension, and zero invalid tails on
partial overwrites. Write-protect the folio spanning the old EOF and
zero its post-EOF range when extending a file, ensuring subsequent
mmap writes advance valid_size.
- Make valid_size and zeroed_size atomic to prevent torn reads and lost
updates. Hold the invalidate lock during truncation, and drain
in-flight direct I/O before buffered writes, buffered fallback, and
page-cache operations that extend valid_size.
- Fall back to single-cluster allocation when a buffered write cannot
allocate its entire range, allowing writes to consume the remaining
free space and return a short count.
- Free clusters allocated beyond EOF after failed or short writes to
prevent leaked space and spurious ENOSPC errors on later writes or
file extensions.
- Clean block-device buffer aliases when allocating clusters so delayed
directory metadata writeback cannot overwrite file data after cluster
reuse.
- Update used_clusters as each cluster is allocated so
partial-allocation cleanup keeps free-space accounting consistent.
Acquire bitmap_lock before checking available space to serialize the
check with allocation.
- Use swap-specific iomap operations to report allocated extents beyond
valid_size as unwritten during swap activation, retaining
byte-accurate SEEK_HOLE and SEEK_DATA reporting in regular I/O.
- Check allocation flags, vendor GUIDs, cluster numbers, data lengths,
and contiguous extents in Vendor Allocation directory entries. Read
complete entry sets during lookup so malformed trailing entries
cannot bypass validation.
- Follow directory FAT chains to their actual end when the recorded
size is too small, supporting devices that leave directory sizes
stale. Handle reads after seeking past the directory end.
- Clear the volume dirty flag during remount only when switching to
read-only without SB_FORCE. Update percent_in_use when changing
volume flags, reporting unknown usage while the volume is dirty or
persistent flags prevent marking it clean.
- Replace runtime division by powers of two with bit operations.
- Document supported mount options, and exfatprogs, and add the
documentation path to MAINTAINERS.

git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/smb
Pull smb server updates from Namjae Jeon:
- Add extended SMB2 directory information support.
Implement FileIdExtdDirectoryInformation, FileId64ExtdDirectoryInformation,
FileId64ExtdBothDirectoryInformation, FileIdAllExtdDirectoryInformation,
and FileIdAllExtdBothDirectoryInformation, including reparse tags, file
attributes, and initialized response padding.
- Track unsigned 64-bit lock ranges in the server lock index, with
conflict detection, blocking waits, cancellation, rollback, and
cleanup for ranges beyond the VFS signed-offset limit.
- Add configurable per-connection session limits.
Reserve slots for new sessions and multichannel bindings, release
them during failure and cleanup, and expose the configured limit
through procfs.
- Validate POSIX negotiate and CREATE contexts, including payload
lengths, extension tags, duplicate contexts, dialect
requirements, and share eligibility. Require POSIX opens for
POSIX file, directory, and filesystem information queries.
- Apply requested POSIX create modes, including mode zero, and NFS
mode ACEs with special permission bits. Enforce append-only
writes and base byte-range lock checks on each open's POSIX
state.
- Complete POSIX metadata responses with filenames, file types,
permission bits, and filesystem device identifiers. Query
filesystem information through the requested open and report the
filesystem fragment size and response length.
- Validate SMB3 encryption transform flags and ensure decrypted
compound requests use the session authenticated by the transform,
including requests containing compressed payloads.
- Serialize negotiation with receive processing, size CREATE
responses for their contexts, reserve UTF-16 terminator space in
stream information, and validate WRITE data against the active
compound request to prevent buffer overruns and stale-data
writes.
- Validate security descriptor offsets before pointer arithmetic,
handle DACL offset overflow on 32-bit systems, and propagate
inode ACL lookup failures safely.
- Deny access through empty DACLs while retaining the owner's
implicit security-management rights. Add KUnit regression
coverage for DACL walk boundaries and maximal-access
calculations.
- Validate RPC pipe ownership for IPC$ reads and writes, and fix
FSCTL_PIPE_TRANSCEIVE handle lookup and response file IDs.
- Fix durable reconnect path validation for symlinked share paths,
shares exporting "/", and handles opened at the share root. Check
path boundaries before comparisons to prevent out-of-bounds reads
and cross-share confusion.
- Rebind completed durable CREATE replays to surviving channels
without draining unrelated requests on the old channel. Transfer
open accounting with the binding and avoid consuming additional
open-file budget during durable reconnects.
- Scope AppInstanceId takeovers to the matching share, path,
stream, and client identity. Check access and AppInstanceVersion
before closing an existing open.
- Retry oplock and lease break notifications through other live
channels, track queued TCP delivery, serialize acknowledgment
updates, and expire unacknowledged breaks while waking blocked
requests.
- Keep lease tables and byte-range lock indexes independent of
their original connection so surviving channels and detached
durable opens retain access to lease and lock state.
- Reclaim ended sessions after logoff and expiration, hold
connection references for session channels, and drain procfs
readers before releasing session table references. Avoid
deadlocks during previous-session teardown and connection
scavenging.
- Prevent file publication after tree disconnect and retain tree
references until final file release. Take parent dentry
references during directory enumeration and serialize directory
emptiness checks with readdir.
- Prevent share-root removal through empty removal paths and return
appropriate errors for directory zero-data requests and temporary
directory attributes.
- Fix named-stream writes, EOF changes, end-of-file reads, and
content copying into rename targets. Reuse existing xattr names,
report sizes by exact xattr name, and avoid emptying streams
after lookup or permission failures.
- Round allocation requests to the advertised allocation unit and
avoid allocation changes that leave on-disk EOF inconsistent with
the in-memory size.
- Inherit FileIds across related compound requests, including
CHANGE_NOTIFY, and use the existing async request machinery for
notify waiting and cancellation.
- Restore share configuration and Kerberos authentication
compatibility with released ksmbd-tools. Advertise extended
session security for raw NTLMSSP when requested by the client.
- Improve Windows chained-compression compatibility, synthesized
AFP_AfpInfo headers, generated short names, and UTF-16 alignment
in partial normalized-name responses.
- Fix interface-query locking, response chaining, link-speed
reporting, and independent IPv4/IPv6 address enumeration. Display
native IPv6 client addresses accurately in procfs.
- Improve SMB Direct socket cleanup by reclaiming failed pending
connections, skipping failed sockets during accept, avoiding
indefinite disconnect waits, and handling unexpected receive
opcodes without triggering kernel warnings.
- Select CRYPTO_AES for SMB3 encryption, replace deprecated system
workqueues, and update feature status documentation and POSIX
specification references.

Pull nfsd updates from Chuck Lever:
"Jeff Layton extended the netlink listener-set operation so that
a management daemon can register NFSD's programs with rpcbind
itself. This prevents an unresponsive rpcbind from stalling NFSD
administration for a minute at a time.
Bulk delegation recall now adjusts the number of delegations it
wants returned, based on memory pressure. The previous mechanism
was spec-conformant, but it requested all delegations to be
returned at once. Clients are free to return few or none in such
cases, but requesting smaller batches of delegations is more
neighborly.
In preparation for handling TLS KeyUpdate, the server's TCP
receive path has been reworked to handle control records. In the
process, the use of sock_recvmsg was replaced with ->read_sock,
which contends less with other holders of the socket lock.
NFSv2 XDR code is now generated by xdrgen, which mechanically
generates the encoders and decoders from the RPC language
specification for the protocol. Replacing hand-built XDR code
makes prototyping new protocol elements faster, reduces errors,
and improves memory safety. Replacement of XDR code for newer NFS
versions will continue in subsequent releases of NFSD.
The remaining bulk of changes in v7.4 is bug fixes, clean-ups, and
small optimizations. Sincere thanks to all contributors,
reviewers, testers, and bug reporters who participated in the v7.4
NFSD development cycle"

If the orangefs userspace client died while writeback was
occurring it led to a gpf. This allows the kernel to finish
the writeback. Reported by Farhad Alemi.
- Don't wait on service operation on system shutdown
This avoids waiting an already dead userspace to process an
unmount operation if the system is shutdown while orangefs
filesystems are still mounted.

used to collect a string size, or possibly a negative error

- Winbond: Add support for W25N04LW and W25N08LW
- Support for ISSI SPI NAND flashes
SPI NOR:
- Support for new Macronix and (lots of) Winbond flash devices
- Rewrite the status register handling. There were many small helper
functions to enable quad I/O mode in many different ways. That's
now consolidated in one generic function.
- Rework the SFPD handling. It used to be only parsed for flashes
present in the in-kernel database which had any of the multi-I/O
bit set - or with the addition of generic flash driver for any
unknown flashes. This left a gap where SFDP wasn't handled and it
turns out newer flashes (with SFDP support) will reused IDs of just
these old flashed. With the rework, SFDP is tried to be parsed for
any flashes and will amend the information which is already present
in the in-kernel database.
- Increase SFDP size limit to 16KiB. There are flashes which have
some larger gaps between tables and thus exceeds the former 4KiB
limit.
- Flash fixups are getting more and more common. Due to this, the
fixups are now a separate list (per manufacturer) instead of being
attached to a specific flash. A new .match() callback makes them
more flexible, when one is applied.
- Support 1-1-8 and 1-8-8 modes with larger flashes which need 4byte
addresses

Pull firewire updates from Takashi Sakamoto:
- Guarantee asynchronous packet and transaction callbacks in process
context
Both the 1394 OHCI driver and the core transaction layer have been
changed to guarantee that asynchronous packet and transaction
callbacks are invoked in process context. In v6.17, the execution
context depended on the transaction destination: callbacks for
transactions destined for remote nodes were invoked from a workqueue,
whereas callbacks for transactions destined for the local node or
terminated due to internal errors were invoked in the transaction
initiator's context.
All such callbacks are now guaranteed to execute in process context,
eliminating the need to account for different execution contexts when
implementing callback functions.
- Fill kerneldoc for transaction layer
The above change guarantees a consistent execution context for packet
and transaction callbacks, making it possible to document their
execution context in kerneldoc.
- Enable compiler-based context analysis for the transaction layer
The core transaction layer is sufficiently complex that
compiler-based context analysis can help detect invalid call paths.
- Fix a reference count leak in the cdev layer
A reference count leak was reported when a user space application
delegated isochronous resource management. This issue has now been
fixed.
- Add KUnit tests for the configuration ROM parser and generator
In recent years, questions have been raised about how the
configuration ROM parser and generator handle boundary conditions and
edge cases. KUnit tests have been added to verify their behavior in
these situations. KUNIT_STATIC_STUB_REDIRECT is used to stub the
transaction responder so that it returns the configuration ROM
contents.

Pull SCSI updates from James Bottomley:
"Small number of driver updates (mpi3mr, ufs, scsi_debug).
By far the biggest core change (at 4000+ lines) is the sense code
rework to make our sense handling follow the 16 bit defines in the
SCSI standard rather than our split ASC and ASCQ handling which ends
up being confusing and difficult to grep.
The changes should all be functionally equivalent and so far the bots
and AI seem to agree; the code has been incubating in -next since 16
September with one reported issue fixed.

Pull io_uring updates from Jens Axboe:
"The bulk of this is a big robustness pass over cancelation, io-wq,
timeouts, and poll. Outside of that:
- Large series from Josef hardening the cancelation, io-wq, timeout,
poll, and wait paths. Fixes for lost wakeups and lost cancels as
io-wq arms poll/timeouts, work stranding on worker exit, CQE32
resize handling, napi entry timeouts, and a pile of smaller
correctness issues across the board
- Rework of how io-wq posts completions, posting from the last
request reference and dropping the request file before the
completion, and running ring release cancelations synchronously -
canceling and waiting for all in-flight requests and dropping
registered files and buffers at release time
- Don't charge the SQ/CQ rings or provided buffer rings to
RLIMIT_MEMLOCK, which the region API conversion had started doing
- Split io_uring_cmd_set_res() out from io_uring_cmd_done() so a
command can set the result from its ->end_io() handler, used by
nvme
- CQE32 ring fixes for the free entry check, aux CQE big_cqe zeroing,
and the dummy skip CQE
- Timeout fixes for sequence handling and multishot updates
- net fixes for MSG_TRUNC buffer overconsumption and keeping recv

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Set supported_speeds in set_pcie_port_type() so sparc64 and
powerpc, which call it via of_create_pci_dev() instead of the usual
pci_setup_device(), correctly set the supported PCIe link speeds
(Stian Halseth)
- When pcie_set_mps() changes MPS, update the value in the saved
state so a subsequent restore doesn't restore an invalid value
(Niklas Cassel)
- Skip Target Speed quirk on clamped ports with no link (Maciej W.
Rozycki)
Driver binding:
- Assume control of portdrv-related features only when portdrv is
enabled, since we can't use them without portdrv (Kuppuswamy
Sathyanarayanan)
- Centralize feature ownership checking so code only needs to check
'host->native_X' and doesn't need to also check 'pcie_ports_native'
(Kuppuswamy Sathyanarayanan)
Error handling:
- Fix leaks when ACPI APEI/GHES error events overflow the kfifo or
mention a device that no longer exists (Priyank Rathod)
- Fix aer_process_err_devices() leak when a device is recorded as an
error source purely by being mentioned in the Root Port Error
Source and the device is inaccessible or logged only masked errors
(Priyank Rathod)
ASPM:
- Disable ASPM when drivers request that, even if the OS doesn't own
ASPM; otherwise drivers do it on their own, which is worse (Ilpo
Järvinen)
Power management:
- Align hibernate poweroff flow with suspend flow for bridges so they
can be powered down at hibernate as they are for suspend (Mario
Limonciello)
- Restore BARs after powering up during enumeration to fix a
regression on devices that don't preserve state in D3hot (Keng-Yu
Lin)
- Avoid D3 on PLX PEX 8532/8533/8548 downstream ports, where putting
them in D3hot takes down the whole switch (Imre Kaloz)
Power control:
- Add GPIO driver for Toshiba TC9563 embedded GPIO controller (Alex
Elder)
- Add DT documentation and pwrctrl driver support for TC9563 embedded
GPIO controller (Lorenzo Bianconi)
- Switch the tc9563 per-port reset to use the GPIO descriptor API
instead of direct regmap accesses (Lorenzo Bianconi)
- Only destroy devices created by pwrctrl core, so that when removing
a PCIe controller driver that uses pwrctrl, we don't remove devices
populated by another mechanism (Shawn Lin)
- Power off child devices on power-on failure (Lorenzo Bianconi)
PCIe native device hotplug:
- Make the 'pciehp_poll_mode' parameter read-only to prevent changes
via sysfs, which can cause errors when unbinding (Runyu Xiao)
Virtualization:
- Read SR-IOV VF Revision ID and Subsystem ID from VF instead of
assuming they're the same as VF 0; they may differ (Logan Odell)
- Add ACS quirk for Pericom PI7C9X2G304 switches (Hans de Goede)
Peer-to-peer DMA:
- Add Zhaoxin KX-6000, KH-40000, KX-6000G, KX-7000, and KH-50000 host
bridges to allowlist (LeoLiu-oc)
- Add Alibaba T-HEAD Yitian 710 host bridge to allowlist (Feng Tang)
- Add Intel Haswell client host bridge to allowlist (Scott Lee)
- Intel Xeon E3/E5/E7 0x6f00 host bridge to allowlist (kai zhang)
- Fix handling of errors in pci_p2pdma_add_resource() to avoid (a)
unmapping a BAR if registering another fails and (b) use after free
of p2p_pgmap (Leon Romanovsky)
- Wait for RCU readers before freeing state to avoid use-after-free
of pdev->p2pdma (Leon Romanovsky)
- Restrict pci_p2pmem_find_many() to providers backed by a pool (Leon
Romanovsky)
- Safely terminate ACS redirect lists to avoid out-of-bounds access
to the buffer (Leon Romanovsky)
- Silence 'Host bridge not in P2PDMA whitelist' warnings unless
caller, e.g., pci_p2pmem_find_many(), requests 'verbose' (Leon
Romanovsky)
Sysfs:
- Return -ENODEV or -EIO sysfs 'label' or 'acpi_index' attributes
when Device Name _DSM fails, not -1, which is interpreted as -EPERM
(Krzysztof Wilczyński)
- Return valid sysfs 'acpi_index' attribute even if the Device Name
_DSM returned an invalid 'label' (Krzysztof Wilczyński)
- Expose sysfs 'acpi_index' and 'label' based on whether the Device
Name _DSM returns valid data, not merely whether the _DSM is
implemented (Krzysztof Wilczyński)
- Avoid out-of-bounds reads of the label returned by the Device Name
_DSM, which is in UTF-16 characters, not bytes (Krzysztof
Wilczyński)
- Reject unaligned resource I/O port accesses, which can oops on
arm64 (Deepanshu Kartikey)
Endpoint framework:
- Pass the correct physical and virtual endpoint function numbers
when setting translation of inbound memory windows (Koichiro Den)
- Make embedded doorbell IRQ non-shared, since currently only the
first EPF can allocate doorbells (Koichiro Den)
- MSI doorbells currently target the first EPF attached to an EPC;
let other EPFs try the embedded doorbell instead of failing when
they can't use the MSI doorbell (Koichiro Den)
- Serialize scan of vNTB virtual PCI bus with other PCI topology
changes (Koichiro Den)
- Manage vNTB lifetimes to avoid leaking virtual devices and buses
and allow removal (Koichiro Den)
- Track vNTB link state from both sides so both see the same
effective link state (Koichiro Den)
- Configure vNTB MSI-X when supported to avoid IOMMU faults and
failure to deliver doorbell interrupts on RC (Koichiro Den)
APM X-Gene PCIe controller driver:
- Use devm for clocks so they're automatically disabled, unprepared,
and released if errors happen during probe (Yuho Choi)
ASPEED PCIe controller driver:
- Fix clk and PHY leaks in aspeed_pcie_port_init() error paths (Liu
Zhenlong)
Broadcom iProc PCIe controller driver:
- Expose devm_pci_alloc_host_bridge_release() so drivers can share a
devm release function even if they don't need the device tree
parsing done by devm_pci_alloc_host_bridge() (Bjorn Helgaas)
- Request only the memory window from BCMA Enumeration ROM and warn
if it doesn't match the one in DT, which fixes an iproc-bcma probe
failure (Semih Baskan)
Broadcom STB PCIe controller driver:
- Replace bool properties for each SoC configuration with a u32
bitvector and a BFLAG() helper (Jim Quinlan)
- Use a similar BQUIRK() helper to test various SoC quirks (Jim
Quinlan)
Cadence PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)
- Return error (not success) from cdns_plat_pcie_probe() if
pm_runtime_get_sync() or cdns_pcie_ep_setup() failed (Vladimir
Oltean)
- Correct the driver data pointer usage; previously .probe() stored
'struct cdns_plat_pcie *', but .shutdown() used the pointer as
'struct cdns_pcie *', resulting in accessing garbage (Linmao Li)
ESWIN PCIe controller driver:
- Publish the platform driver MODULE_DEVICE_TABLE so the driver can
be autoloaded when built as a module (Pengpeng Hou)
Freescale i.MX6 PCIe controller driver:
- Fix resource and pwrctrl device leaks .probe() (Zhijian Han)
- Improve i.MX95 Gen3 link stability by changing MPLLB_BANDWIDTH from
default 120 to 140 (Richard Zhu)
- Use dev_err_probe() in host init error path to silence
-EPROBE_DEFER messages (Alexander Stein)
- Avoid dereferencing NULL clock names when 'clocks' includes more
phandles than 'clock-names' has names (Rudi Heitbaum)
- Add suspend_poweroff flag so platforms like i.MX that power off RC
controllers during suspend can enter L2 so endpoints can get
PME_Turn_Off notifications before power loss (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Enable PROBE_PREFER_ASYNCHRONOUS to reduce probe time of the four
controllers on LX2160A (Vincent Jardin)
Intel VMD host bridge driver:
- Flush DMA writes before handling MSI on Meteor Lake: MSI may arrive
before write has completed, resulting in an nvme 30 second stall
before a QID timeout and possibly other similar problems (Rickey
Bartlett)
- Flush DMA writes before handling MSI on Arrow Lake (Vladimir
Nedoshivin)
Marvell Aardvark PCIe controller driver:
- Disable PHY on probe failures (Myeonghun Pak)
Marvell MVEBU PCIe controller driver:
- Refcount child OF nodes during .probe() to make a concurrent OF
overlay removal safe (Krzysztof Kozlowski)
MediaTek PCIe controller driver:
- Find INTx DT property by 'interrupt-controller' name instead of
assuming it's the first child node (Zhengping Zhang)
MediaTek PCIe Gen3 controller driver:
- Fix a 64-bit type truncation in mtk_pcie_set_trans_table() to avoid
issues with windows above or larger than 4GB (Sreeraj S Kurup)
NVIDIA Tegra264 PCIe controller driver:
- Fix the Link Capabilities offset so we read the correct register
(Bjorn Helgaas)
Qualcomm PCIe controller driver:
- Only collect reset GPIOs from PCI bridge DT nodes to avoid stealing
resets used by downstream devices like USB controllers (Christopher
Obbard)
- Block accesses to downstream devices on link down to reduce a storm
of Completion Timeout AER interrupts (Qiang Yu)
- Skip system suspend/resume for firmware-managed PCIe, where
firmware manages clocks, regulators, resets, etc (Mrinmay Sarkar)
- Honor IOMMU provider's #iommu-cells in qcom_pcie_config_sid_1_9_0()
(Manivannan Sadhasivam)
- Deinitialize endpoint on remove (Guangshuo Li)
- Treat Root Port error recovery as successful even if link doesn't
come up after reset because the device was hot-unplugged (Konrad
Dybcio)
- Skip unnecessary iMSI-RX initialization if DT 'msi-map' is present,
indicating an external MSI controller (Ayiluri Naga Rashmi)
Renesas R-Car PCIe controller driver:
- Limit Max_Read_Request_Size to 256 to avoid hardware erratum (Marek
Vasut)
- Support PERST# via reset subsystem as well as the existing GPIO
support to prepare for R-Car Gen5 SoCs (Marek Vasut)
- Add DT and driver support for the R-Car Gen 5 X5H (R8A78000) PCIe
Gen 4 core (Marek Vasut)
- Add Application/Local register reset DT description and driver
support for both host and endpoint mode (Marek Vasut)
- Add PM ops so controller works after suspend/resume (Marek Vasut)

Prabhakar)
- Add RZ/G3L (R9A08G046) DT and driver support (Biju Das)
Rockchip PCIe controller driver:
- Limit host and endpoint controllers to 2.5 GT/s since 5.0 GT/s is
unsafe per Rockchip (Geraldo Nascimento)
Synopsys DesignWare PCIe controller driver:
- Set DMA_BYPASS bit in outbound IATU CTRL2 register to avoid data
corruption if the iATU translates DMA engine transactions (Sumit
Kumar)
- Use FIELD_PREP() to remove need for *_SHIFT definitions (Hans
Zhang)
TI DRA7xx PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)
- Fix optional clock leak when .probe() fails by using
devm_clk_get_optional_enabled() (Felix Gu)
TI Keystone PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)
UltraRISC PCIe controller driver:
- Allow DWC drivers to skip outbound iATU setup if they don't need
translation between CPU and PCI addresses (Xincheng Zhang)

Commit fbb22ceaaf8f ("powerpc/irq: Make irqstats array based") made
arch_show_interrupts() call irq_proc_emit_counts(). That function lives
in kernel/irq/proc.c, which is only built with CONFIG_PROC_FS, so
kernels without procfs no longer link:
powerpc64-linux-ld: arch/powerpc/kernel/irq.o: in function `arch_show_interrupts':
arch/powerpc/kernel/irq.c:134:(.text+0x4b8c): undefined reference to `irq_proc_emit_counts'
arch_show_interrupts() is only called from irq_seq_show(), which is in
kernel/irq/proc.c as well, so build it only with CONFIG_PROC_FS, as x86
already does.

Pull KVM updates from Paolo Bonzini:
"ARM:
- pKVM state isolation: years after pKVM started being enabled
upstream, we finally get the basics in the form of state isolation.
The vcpu state is now off-limit for the host for protected VMs
- pKVM also grows a hypervisor-private memory allocator, allowing it
to deal with sub-page allocation, much like everywhere else
- pKVM also lands a trace_printk() equivalent, which hopefully will
make debugging a bit easier
- First shot at annotating portions of the KVM/arm64 code to be
extracted and built on s390. The real fun is yet to come
- Allow pre-faulting of stage-2 canonical mappings from userspace,
joining x86 and s390 in implementing this feature
- Add a reverse mapping infrastructure for shadow stage-2,
significantly improving performance when MMU notifiers kick in, and
avoiding full unmap of all shadow tables for this VM
- Next step of GICv5 enablement, adding support for the IRS block,
and providing both SPI and LPI support. This is the first point
where KVM/arm64 can support an SMP GICv5 guest
- As a preliminary to eventually enabling CCA, add a bunch of
infrastructure to KVM/arm64, splitting some of the basic operations
into individual backends (normal VM, normal pKVM VM, protected pKVM
VM). This allows CCA to later slot in without polluting the rest of
KVM with its firmware-driven nonsense
- Make ID registers immutable from the point where a vcpu is able to
run, even if it fails to run. This prevents KVM from sampling
untrusted values
- Restore some type checking to the EL2 object. KVM/arm64 originally
had some strong type checking between the kernel and the EL2
object, but lost it along the way when the private hypercall
interface was (somewhat pointlessly) converted to SMCCC. Type
checking is back, syscall style, and with added sparse goodies
- Expand the FFA support to FFA_NOTIFICATION_*, and add some
sanitisation of the protocol that pKVM relays to the "trusted"
runtime
- Make GICv3 RD assignment more robust to userspace nonsense
- Convert the remaining MMU fault handler backends to
kvm_s2_fault_vma_info and co., fixing a number of bugs in the
process
- Fix the SError/SEA selftests to be both more robust and less
braindead
- Fix a smattering of documentation bugs, some of them as a result of
our AI friends spitting out credible assertions based on
non-existing symbols
- The usual collection of low impact bug fixes (SMCCC, timers, PMU)
Loongarch:
- Add separate vmid support
- Simplify MSI interrupt injection
- Add crash hypercall support
- Allow to set pv_feature until vCPU run
- Enable HW page table walk automatically in selftests
s390:
- rework page allocation for secure guest variable storage
- Selftests and documentation improvements
- Replace get_zeroed_page with kzalloc
- Fix corner cases of floating interrupt injection
- Initial arm64 on s390 support
x86:
- Clean up the handling of vcpu->arch.xen.long_mode to be consistent
and correctly handle 32-bit/64-bit alignment, and various other bug
fixes have accumulated over the months since v1
- Grab KVM's SRCU "lock" in kvm_zap_gfn_range() to fix a recurring
bug where callers fail to do so
- Fix a variety of issues in the pre-fault code that are mostly
benign in the current code base, but will show up in big ways
if/when the pre-faulting logic is used to implementing
prefetch-on-fault for the TDP MMU
- For PREEMPT_RT=y kernels, drop the rmaps' individual bit-spinlock
and just walk the rmaps' with mmu_lock taken. On the write side
(which always uses mmu_lock), the bit-spinlock was assuming that
preemption was disabled, but that is *not* true when rwlocks become
sleepable
- Prepare a memory_fault exit (paired with -EFAULT) when KVM hits an
error PFN, e.g. so that userspace can resolve transient issues
instead of killing the guest. Convert a variety of WARN()+EFAULT
paths into KVM_BUG_ON()+EIO so that KVM can hard commit to filling
memory_fault on -EFAULTs that occur in the page fault path
- Fix a NX hugepage un-accounting bug where KVM would always uncharge
the shadow MMU, even when handling TDP MMU pages
- Mask off the address space ID when checking for illegal usage of
kvm_set_internal_memslot() to prevent false negatives on the sanity
check
- Explicitly zero reserved flags when delivering a SynIC message to
avoid leaking a byte of stack information to the guest
- Rework TDX's handling of the canonical MMU root level to not rely
on userspace to fill CPUID correctly, as doing so lets userspace
trivially trigger a KVM_BUG_ON()
- Reject KVM_SET_NESTED_STATE if userspace "restores" L1 with
EFER.LMA=1 && EFER.LME=0, which confuses KVM into trying to
configure an 64-bit MMU without PAE
- Ignore EFER.LMA (clear it from KVM's cached save state) if
EFER.LME=0 when preparing L2 state, to fix another way to confuse
KVM's MMU (and because real hardware also ignores EFER.LMA)
- Improve KVM's sanity checks for a misconfigured MMU to (hopefully)
detect all of the ways KVM can botch EFER.LMA vs. CR4.PAE
- Remove the "full" out-param from kvm_x86_ops.flush_tlb_gva() as the
param is only used to avoid what effectively amounts to a single
memory write
- Fix a mostly-benign bug where KVM can write through a guest's
read-only mapping due to not checking the error code when
expediting emulated MMIO page faults
- Honor the guest's view of the "EFER.LMSLE must be zero" defeature
so that userspace can provide migration compatibility between Rome
and Milan+
- Pend a KVM_REQ_EVENT request when an exception is morphed into a
nested VM-Exit, otherwise KVM can fail to actually deliver the
nested VM-Exit, e.g. when injecting a page fault
- Add support for PML on SVM
- Add support for virtualizing Bus Lock Detect on SVM, and fix a
number of DR6 bugs and warts along the way
- Fix a variety of warts in KVM's handling of guest TSC, kvmclock,
and timekeeping in general, as a (big) first step towards
addressing several longstanding problems with the kvmclock
implementation. Most notably, fix a precision issue where
get_kvmclock_ns() computed the clock from the *host* TSC without
applying guest TSC scaling, causing systemic drift from the values
the guest computes from its own TSC
- Rip out KVM's shadow timekeeping structures, now that ktime
snapshots are powerful enough to replace it
- Misc fixes and cleanups
x86 (AMD):
- Fix a benign-in-practice bug where KVM unintentionally sets a
non-zero error code when delivering exceptions to SEV-ES+ guests
- Force a new ASID in both VMCBs on pCPU migration to fix a bug where
KVM can run a VMCB with a stale ASID due to the tracking being
per-CPU, not per-VMCB
- Return INVALID_INPUT to the guest instead of exiting to userspace
with -EIO if KVM can't access "guest request" buffer, i.e. try to
keep the guest alive if the guest or userspace goofs
x86 (Intel):
- Enable Notify VM-Exits (now called Instruction Timeout in the SDM)
and Bus Lock VM-Exits for TDX guests when they're enabled by
userspace (KVM forgot to wire up the TDX Module knobs)
- Move all common (between VMX and TDX) APIs/helpers to
common.h/main.c, and change all namespace prefixes from "vmx" to
"vt"
- Fix a thankfully benign bug (due to other areas of KVM being
hardened) where userspace can bypass INIT_MEM_REGION's address wrap
check by providing a nr_pages that will overflow a u64 when
converted to bytes, and fix an also- benign off-by-one bug in the
check (inclusive vs. exclusive)
- Set the vmcs.GUEST_ACTIVITY_STATE back to ACTIVE when userspace
sets KVM's mp_state to anything other than HALTED, e.g. so that a
vCPU doesn't get stuck in HLT if userspace emulates RESET
guest_memfd:
- Take the invalidate lock when unbinding a dying file to fix a race
with kvm_gmem_invalidate_end() that results in KVM leaving the MMU
invalidation count elevated. Not taking the lock in the first place
was pure misguided paranoid
- When binding a memslot, purge the bindings if storing the new
memslot fails, as Xarray's "store range" API can subtly fail
partway through
- Establish memslot<=>guest_memfd bindings *after* the memslot is
ready, as the memslot becomes reachable the instant the binding is
installed
- Don't grab a page refcount when reloading an SNP VMSA and stop
returning a "struct page" from guest_memfd's PFN lookup altogether,
to ensure that KVM doesn't hold any unnecessary refcounts (the
lifetime of the page is ensured by MMU notifiers and similar
hooks). Preventing unnecessary refcounts greatly simplifies
supporting in-place SHARED=>PRIVATE conversions
- Add support for in-place PRIVATE<=>SHARED conversion, i.e. allow a
single guest_memfd instance to be used for both PRIVATE and SHARED
variations of CoCo guests' memory (though not at the same time).
This eliminates the need to double allocate guest memory for TDX
and SNP, and is basically a hard requirement for pKVM, which relies
on being able to preserve memory contents on conversions
- Hack-a-fix a deadlock bug in ->error_remove_folio() by returning
-EBUSY if the filemap invalidate lock is contended. Punt on a
proper fix for the moment, as a proper fix likely involves
reworking truncate_error_folio()
- Add a pile of selftests for in-place conversions
- Misc guest_memfd cleanups
Generic:
- Move some configuration items to preprocessor symbols, to help with
arm-on-s390's need to compile the same code twice with different
values
- Allow KVM implementations to choose alternative device names, also
for s390's support of ARM virtualmachines
- Switch the KVM-VFIO interface and external consumers over to
standard file-based reference counting, eliminating all external
KVM symbol exports
Selftests:
- Rework KVM selftest's handling of memory regions all so that PPC
can force its page table allocations to be naturally aligned
- PPC support
- Fix emulation of VMPTRST and VMPTRLD when eVMCS is in-use to match
real Hyper-V's behavior
- Saturate L2's TSC frequency if stacking L1 and L2 scaling
multipliers exceeds what hardware supports, as attempting to run L2
with an illegal multiplier will either cause VM-Entry to fail (VMX)
or trigger a #GP when writing MSR_AMD64_TSC_RATIO (SVM). The #GP is
thankfully benign in the grand scheme as even "unsafe" WRMSRs have
exception fixup
- Rework KVM selftest's handling of memory regions so that PPC can
force its page table allocations to be naturally aligned
- Clean up selftest's VMX instruction helpers, and drop an absurd
number of completely useless return values, e.g. functions that
unconditionally return %true and then have every caller assert
success
- Add selftests support for Zhaoxin CPUs
- Overhaul the TSC scaling test to add a regression test for the
saturation behavior, and to increase its coverage in general
- Fix selftests usage various NUMA syscalls to account for an
undocumented, but known since 2007, off-by-one kernel bug. Add
helpers to try and avoid re-introducing the same flaws in the
future
- Automatically run xAPIC IPI migration test (between NUMA nodes)
when possible, as the entire point of the test is verify KVM's
handling of page migration of the APIC backing page
- Misc cleanups"

Pull bpf updates from Alexei Starovoitov:
"Major changes:
- Introduce scalar evolution (SCEV) analysis in the verifier.
It infers how registers and stack slots change in a loop and lets
the verifier check bounded loops with induction variables as ranges
instead of walking every iteration. The number of processed insns
drops ten fold in programs with loops (Eduard Zingerman)
- Add 'callx' instruction: indirect call of a static BPF subprogram.
The address is taken with ld_imm64 or loaded from read-only data.
Supported by x86-64, arm64 and riscv64 JITs (Alexei Starovoitov, Pu
Lehui)
- Add unwind_goto and unwind_exit instructions, so that Rust panic or
C++ exception can run destructors of every frame it passes through.
The normal path is free of unwind code. Supported by x86-64 and
arm64 JITs (Alexei Starovoitov)
- Support programs compiled by rust-bpf: treat load and store through
a number as arena access with BPF_F_ARENA_SCALAR, accept rust names
in BTF (Alexei Starovoitov)
- Raise BPF program stack size from 512 bytes to 2 KiB on x86-64 and
arm64 (Kumar Kartikeya Dwivedi)

returned by value in BPF subprograms and kfuncs, and fix x86-64 and
arm64 trampolines for such arguments (Yonghong Song)
- Introduce a common way to attach struct_ops to a cgroup via
bpf_link. bpf_tcp_ops is the first user and mirrors TCP sock_ops
callbacks (Martin KaFai Lau, Amery Hung)
- Describe inlined functions in BTF. New kinds tell where the inline
sites are and how to fetch the arguments there.
CONFIG_DEBUG_INFO_BTF_INLINE keeps it apart from the main BTF in
.BTF.inline section or in btf_vmlinux_inline.ko (Alan Maguire)
- Fix many memory safety, lifetime and locking bugs in BPF core,
verifier, iterators, local storage, dynptr, devmap, cpumap and
seg6local (Josef Bacik, Alexei Starovoitov)
- Diff stat is dominated by selftests and by removal of
lib/test_bpf.c. Its 16k lines of instruction tests were converted
to BPF selftests that BPF CI runs on every architecture it covers
(Daniel Borkmann)
Other features and fixes:
- Add KASAN checks to memory accesses of JITed programs on x86-64
(Alexis Lothoré)
- Complete unification of helper, kfunc and subprog argument checks
in the verifier (Amery Hung)
- Add bpf_copy_from_user_mm[_str]() kfuncs (Anastasios Papagiannis)

- Add BPF_PROG_STREAM_OPEN command to read BPF streams through a
file descriptor with poll support
- Let kernel structs publish arena pointers with __arena type tag
- Fix __uninit kfunc output buffers and fastcall rewrite with

Pull bootconfig updates from Masami Hiramatsu:
"Parser robustness and validation improvements:
- Skip printing early params to cmdline from bootconfig
Suppress early_param keys from /proc/cmdline and warn the user,
since bootconfig does not invoke early_param handlers and silently
ignoring them is misleading
- Reject unexpected data after null character
Detect and reject non-null data following an intermediate null
character in the bootconfig buffer, preventing silently ignored
configuration after an early termination
Code cleanups:
- Merge _xbc_exit() into xbc_exit()
Since memblock_free() now handles late freeing and NULL addresses,
the separate _xbc_exit() helper and its early argument are
unnecessary. Inline it into xbc_exit()
- Remove redundant assignment in xbc_parse_array()
The node->child = 0 assignment after the loop duplicates what
xbc_init_node() already did
- Skip internal tree sanity checks in kernel
Move the node index bounds loop from xbc_verify_tree() into a
userspace-only xbc_sanity_check_tree() to reduce boot-time
overhead, since out-of-bounds indices cannot be produced by
malformed input
- Move BOOTCONFIG_FOOTER_SIZE to include/linux/bootconfig.h
Share the footer size constant between kernel and user-space tools,
replacing the hardcoded (BOOTCONFIG_MAGIC_LEN + 8) expression in
init/main.c
Tooling improvements:
- Remove unused PAGE_SIZE macro from the bootconfig tool
- Consolidate xbc_init() to error message wrapper
Use init_xbc_with_error() for all bootconfig initialization paths
in the tool for simpler and more consistent error handling"

Pull probes updates from Masami Hiramatsu:
"Asynchronous optprobe optimizer and cleanups:
- Make optprobe optimizer multi-generational and asynchronous
Rework the optimizer as a state machine to avoid calling
time-consuming synchronize_rcu_tasks() while holding kprobe_mutex,
text_mutex, and cpus_read_lock(). Uses call_rcu_tasks() and a fixed
ring of generation slots instead, so locks are only held during the
brief instruction- patching window
- Use DEFINE_DEBUGFS_ATTRIBUTE for the kprobes enabled knob
Replace a hand-rolled debugfs read/write pair (dating from 2007)
with the proper DEFINE_DEBUGFS_ATTRIBUTE macro, removing dead code
and the stale XXX comment
Code quality and documentation cleanups:
- Add const qualifier to new_argv allocation type in trace_probe.c,
preparing for the type-aware kmalloc_obj allocator conversion
- Clarify btf_find_struct_member() container parameter
Rename the misleading @member_type parameter to @container_type and
add proper kernel-doc documentation for all parameters and return
values
Boot tracing test framework and testcases:
- Add a generic boot tracing test framework under
tools/testing/selftests/ftrace/boottime/
The test runner builds a minimal initramfs with busybox, boots
QEMU, and runs tracefs checker scripts, supporting bootconfig,
kernel command-line options, and multi-boot crash/reboot scenarios
- Add boot-time tracing testcases
Verify dynamic kprobe, synthetic events, eprobe, fprobe, tprobe,
and trace instance creation via bootconfig
- Add kernel cmdline tracing testcases
Verify ftrace, trace_event, trace_buf_size, trace_options,
trace_clock, and trace_instance kernel parameters
- Add persistent ring buffer testcases:
Verify memory reservation via reserve_mem= and trace data retention
across guest crash/reboot, as well as backup instance creation and
boot log preservation
- Change non-unique test symbol from name_show to init_once in
kprobe_non_uniq_symbol.tc for more reliable cross-architecture
testing"

Pull ring-buffer updates from Steven Rostedt:
- Add Vincent Donnefort as ring-buffer maintainer
Vincent has been doing a lot of updates to the ftrace ring buffer
lately. I'm going to start delegating updates for the ring buffer to
him.
- Use RING_BUFFER_MIN_NR_PAGES instead of open coding the number 2
Instead of using the number 2 as the minimum number of pages that a
ring buffer may have, create and use a macro
RING_BUFFER_MIN_NR_PAGES.
- Clean up the resize_disabled_checks
There's duplication of code to check for resize disabled. Create a
helper function rb_resize_disabled() and use that. Not only does it
put the code in one place, it also removed a redundant check.
- Remove unnecessary cpumask_test_cpu checks
The loop for_each_buffer_cpu(buffer, cpu) only loops over CPUs in the
buffer->cpumask. There's no reason to test if the CPU is set in that
same loop.
- Take cpus_read_lock() when changing the subbuf order
A CPU coming on line for the first time allocates its CPU buffer. But
if this happens while the subbuffer is being resized, it can cause an
inconsistent state of subbufer sizes in the buffer. Add a
cpus_read_lock() to ring_buffer_subbuf_order_set() to prevent this
race.

Pull ftrace updates from Steven Rostedt:
- Have the stacktrace option work with func-args
The func_stack_trace option has it's own ftrace handler and so does
the func-args option. When they are both set, neither would run. The
function tracer itself would error out.
Allow the stacktrace and function args to work together.
- Avoid BTF lookup in atomic context
The ftrace_dump() can call function graph tracing output from an
atomic context (like an NMI watchdog going off). The BTF lookup is
not safe to call from atomic context. Have btf_find_func_proto()
return if in atomic context.
- Build trace_btf.c when CONFIG_DEBUG_INFO_BTF is enabled
New code is depending on trace_btf.c but that only gets built when
BPF_SYSCALL is also enabled. As the new code doesn't depend on that,
have trace_btf.c get built with just DEBUG_INFO_BTF set.
- Have function graph return values have BTF processing
Have the return values printed by the function graph tracer use BTF
to print the values in better format. For example, if it's a char,
short, signed or unsigned, print according to the value defined by
BTF.
- Add a "max" field to the function profiler stats
The function profiler shows all the functions run in the kernel, the
number of times they are called, and the total time they took up.
Also add a "max" field which holds the longest time a function ran
for.
- Fix memory leak in module with all skipped functions
On module load, the ftrace entries are recorded to keep track of what
functions can be traced or not. Some functions may be skipped for
various reasons (some defined by the architecture). If all functions
in the module are skipped, its data page is not freed and can leak.
Catch this case and free the empty page.
- Allow architectures to reject functions from being traced
Allow architectures to skip a function address by returning zero from
ftrace_call_adjust().
- Initialize modname and offset in print_rec()
The variables modname and offset are initialized by
kallsyms_lookup(). If that fails, the values are not set, but the
code continues to print other information. The modname and offset are
used later, but if the kallsyms_lookup() failed, they will not be
set.
If a module is being loaded and unloaded at the same time as reading
the available_filter_functions file, it can cause a fault due to the
lookup failing and modname and offset being used uninitialized.
