wifi: cfg80211: add regulatory flag to allow VLP AP operation
Add a regulatory flag to allow VLP AP operation even on channels otherwise marked NO_IR, which may be possible in some regulatory domains/countries. Note that this requires checking also when the beacon is changed, since that may change the regulatory power type.

uprobe: Wire up uretprobe system call
Wiring up uretprobe system call, which comes in following changes. We need to do the wiring before, because the uretprobe implementation needs the syscall number. Note at the moment uretprobe syscall is supported only for native 64-bit process.

"Misc:
- Restore debugfs behavior of ignoring unknown mount options
- Fix kernel doc for netfs_wait_for_oustanding_io()
- Fix struct statx comment after new addition for this cycle
- Fix a check in find_next_fd()
iomap:
- Fix data zeroing behavior when an extent spans the block that
contains i_size
- Restore i_size increasing in iomap_write_end() for now to avoid
stale data exposure on xfs with a realtime device
Cachefiles:
- Remove unneeded fdtable.h include
- Improve trace output for cachefiles_obj_{get,put}_ondemand_fd()
- Remove requests from the request list to prevent accessing already
freed requests
- Fix UAF when issuing restore command while the daemon is still
alive by adding an additional reference count to requests
- Fix UAF by grabbing a reference during xarray lookup with xa_lock()
held
- Simplify error handling in cachefiles_ondemand_daemon_read()
- Add consistency checks read and open requests to avoid crashes
- Add a spinlock to protect ondemand_id variable which is used to
determine whether an anonymous cachefiles fd has already been
closed
- Make on-demand reads killable allowing to handle broken cachefiles
daemon better
- Flush all requests after the kernel has been marked dead via
CACHEFILES_DEAD to avoid hung-tasks
- Ensure that closed requests are marked as such to avoid reusing
them with a reopen request
- Defer fd_install() until after copy_to_user() succeeded and thereby
get rid of having to use close_fd()
- Ensure that anonymous cachefiles on-demand fds are reused while
they are valid to avoid pinning already freed cookies"

dlm: introduce DLM_LSFL_SOFTIRQ_SAFE
Introduce a new external lockspace flag DLM_LSFL_SOFTIRQ_SAFE. A lockspace user will set this flag if it can handle dlm running the callback functions from softirq context. When not set, dlm will continue to run callback functions from the dlm_callback workqueue. The new lockspace flag cannot be used for user space lockspaces, so a uapi placeholder definition is used for the new flag value.

KVM: x86: Add KVM_RUN_X86_GUEST_MODE kvm_run flag
When a vCPU is interrupted by a signal while running a nested guest, KVM will exit to userspace with L2 state. However, userspace has no way to know whether it sees L1 or L2 state (besides calling KVM_GET_STATS_FD, which does not have a stable ABI). This causes multiple problems: The simplest one is L2 state corruption when userspace marks the sregs as dirty. See this mailing list thread [1] for a complete discussion. Another problem is that if userspace decides to continue by emulating instructions, it will unknowingly emulate with L2 state as if L1 doesn't exist, which can be considered a weird guest escape. Introduce a new flag, KVM_RUN_X86_GUEST_MODE, in the kvm_run data structure, which is set when the vCPU exited while running a nested guest. Also introduce a new capability, KVM_CAP_X86_GUEST_MODE, to advertise the functionality to userspace.

KVM: x86: Add a capability to configure bus frequency for APIC timer
Add KVM_CAP_X86_APIC_BUS_CYCLES_NS capability to configure the APIC
bus clock frequency for APIC timer emulation.
Allow KVM_ENABLE_CAPABILITY(KVM_CAP_X86_APIC_BUS_CYCLES_NS) to set the
frequency in nanoseconds. When using this capability, the user space
VMM should configure CPUID leaf 0x15 to advertise the frequency.
Vishal reported that the TDX guest kernel expects a 25MHz APIC bus
frequency but ends up getting interrupts at a significantly higher rate.
The TDX architecture hard-codes the core crystal clock frequency to
25MHz and mandates exposing it via CPUID leaf 0x15. The TDX architecture
does not allow the VMM to override the value.
In addition, per Intel SDM:
"The APIC timer frequency will be the processor’s bus clock or core
crystal clock frequency (when TSC/core crystal clock ratio is
enumerated in CPUID leaf 0x15) divided by the value specified in
the divide configuration register."
The resulting 25MHz APIC bus frequency conflicts with the KVM hardcoded
APIC bus frequency of 1GHz.
The KVM doesn't enumerate CPUID leaf 0x15 to the guest unless the user
space VMM sets it using KVM_SET_CPUID. If the CPUID leaf 0x15 is
enumerated, the guest kernel uses it as the APIC bus frequency. If not,
the guest kernel measures the frequency based on other known timers like
the ACPI timer or the legacy PIT. As reported by Vishal the TDX guest
kernel expects a 25MHz timer frequency but gets timer interrupt more
frequently due to the 1GHz frequency used by KVM.
To ensure that the guest doesn't have a conflicting view of the APIC bus
frequency, allow the userspace to tell KVM to use the same frequency that
TDX mandates instead of the default 1Ghz.

dma-buf: align fd_flags and heap_flags with dma_heap_allocation_data
dma_heap_allocation_data defines the UAPI as follows:
struct dma_heap_allocation_data {
__u64 len;
__u32 fd;
__u32 fd_flags;
__u64 heap_flags;
};
However, dma_heap_buffer_alloc() casts both fd_flags and heap_flags
into unsigned int. We're inconsistent with types in the non UAPI
arguments. This patch fixes it.

TTY fix for 6.10-rc2
Here is a single revert for a much-reported regression in 6.10-rc1 when it comes to a few older architectures.

RDMA/bnxt_re: Expose the MSN table capability for user library
BNXT_RE_COMP_MASK_UCNTX_HW_RETX_ENABLED was introduced to share the HW retransmit capability between driver and lib. The main difference in implementation for HW Retransmit support is the usage of MSN table or PSN table . When HW retrans is enabled, HW expects MSN table to be allocated by driver/lib, else PSN table (for older adapters). FW expose a new field which gives MSN capability. Drivers and libs can depend on the new field instead of HW Retrasns capability. For adapters which support HW_RETX feature, MSN table capability will be set. For older adapters, this value will be 0(to maintain backward compatibility with older FW). Rename UAPI just to capture the correct name of the HW capability that driver/library is interested in. No functional impact even if older rdma-core is used.

mseal: wire up mseal syscall
Patch series "Introduce mseal", v10.
This patchset proposes a new mseal() syscall for the Linux kernel.
In a nutshell, mseal() protects the VMAs of a given virtual memory range
against modifications, such as changes to their permission bits.
Modern CPUs support memory permissions, such as the read/write (RW) and
no-execute (NX) bits. Linux has supported NX since the release of kernel
version 2.6.8 in August 2004 [1]. The memory permission feature improves
the security stance on memory corruption bugs, as an attacker cannot
simply write to arbitrary memory and point the code to it. The memory
must be marked with the X bit, or else an exception will occur.
Internally, the kernel maintains the memory permissions in a data
structure called VMA (vm_area_struct). mseal() additionally protects the
VMA itself against modifications of the selected seal type.
Memory sealing is useful to mitigate memory corruption issues where a
corrupted pointer is passed to a memory management system. For example,
such an attacker primitive can break control-flow integrity guarantees
since read-only memory that is supposed to be trusted can become writable
or .text pages can get remapped. Memory sealing can automatically be
applied by the runtime loader to seal .text and .rodata pages and
applications can additionally seal security critical data at runtime. A
similar feature already exists in the XNU kernel with the
VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall
[4]. Also, Chrome wants to adopt this feature for their CFI work [2] and
this patchset has been designed to be compatible with the Chrome use case.
Two system calls are involved in sealing the map: mmap() and mseal().
The new mseal() is an syscall on 64 bit CPU, and with following signature:
int mseal(void addr, size_t len, unsigned long flags)
addr/len: memory range.
flags: reserved.
mseal() blocks following operations for the given memory range.
1> Unmapping, moving to another location, and shrinking the size,
via munmap() and mremap(), can leave an empty space, therefore can
be replaced with a VMA with a new set of attributes.
2> Moving or expanding a different VMA into the current location,
via mremap().
3> Modifying a VMA via mmap(MAP_FIXED).
4> Size expansion, via mremap(), does not appear to pose any specific
risks to sealed VMAs. It is included anyway because the use case is
unclear. In any case, users can rely on merging to expand a sealed VMA.
5> mprotect() and pkey_mprotect().
6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous
memory, when users don't have write permission to the memory. Those
behaviors can alter region contents by discarding pages, effectively a
memset(0) for anonymous memory.
The idea that inspired this patch comes from Stephen Röttger’s work in
V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this
API.
Indeed, the Chrome browser has very specific requirements for sealing,
which are distinct from those of most applications. For example, in the
case of libc, sealing is only applied to read-only (RO) or read-execute
(RX) memory segments (such as .text and .RELRO) to prevent them from
becoming writable, the lifetime of those mappings are tied to the lifetime
of the process.
Chrome wants to seal two large address space reservations that are managed
by different allocators. The memory is mapped RW- and RWX respectively
but write access to it is restricted using pkeys (or in the future ARM
permission overlay extensions). The lifetime of those mappings are not
tied to the lifetime of the process, therefore, while the memory is
sealed, the allocators still need to free or discard the unused memory.
For example, with madvise(DONTNEED).
However, always allowing madvise(DONTNEED) on this range poses a security
risk. For example if a jump instruction crosses a page boundary and the
second page gets discarded, it will overwrite the target bytes with zeros
and change the control flow. Checking write-permission before the discard
operation allows us to control when the operation is valid. In this case,
the madvise will only succeed if the executing thread has PKEY write
permissions and PKRU changes are protected in software by control-flow
integrity.
Although the initial version of this patch series is targeting the Chrome
browser as its first user, it became evident during upstream discussions
that we would also want to ensure that the patch set eventually is a
complete solution for memory sealing and compatible with other use cases.
The specific scenario currently in mind is glibc's use case of loading and
sealing ELF executables. To this end, Stephen is working on a change to
glibc to add sealing support to the dynamic linker, which will seal all
non-writable segments at startup. Once this work is completed, all
applications will be able to automatically benefit from these new
protections.
In closing, I would like to formally acknowledge the valuable
contributions received during the RFC process, which were instrumental in
shaping this patch:
Jann Horn: raising awareness and providing valuable insights on the
destructive madvise operations.
Liam R. Howlett: perf optimization.
Linus Torvalds: assisting in defining system call signature and scope.
Theo de Raadt: sharing the experiences and insight gained from
implementing mimmutable() in OpenBSD.
MM perf benchmarks
==================
This patch adds a loop in the mprotect/munmap/madvise(DONTNEED) to
check the VMAs’ sealing flag, so that no partial update can be made,
when any segment within the given memory range is sealed.
To measure the performance impact of this loop, two tests are developed.
[8]
The first is measuring the time taken for a particular system call,
by using clock_gettime(CLOCK_MONOTONIC). The second is using
PERF_COUNT_HW_REF_CPU_CYCLES (exclude user space). Both tests have
similar results.
The tests have roughly below sequence:
for (i = 0; i < 1000, i++)
create 1000 mappings (1 page per VMA)
start the sampling
for (j = 0; j < 1000, j++)
mprotect one mapping
stop and save the sample
delete 1000 mappings
calculates all samples.
Below tests are performed on Intel(R) Pentium(R) Gold 7505 @ 2.00GHz,
4G memory, Chromebook.

Based on the result, for 6.8 kernel, sealing check adds
20-40 nano seconds, or around 50-100 CPU cycles, per VMA.
In addition, I applied the sealing to 5.10 kernel:

From 5.10 to 6.8
munmap: added 250-550 ns in time, or 500-1100 in cpu cycle, per vma.
mprotect: added 200-750 ns in time, or 500-1200 in cpu cycle, per vma.
madvise: added 33-50 ns in time, or 70-110 in cpu cycle, per vma.
In comparison to mseal, which adds 20-40 ns or 50-100 CPU cycles, the
increase from 5.10 to 6.8 is significantly larger, approximately ten times
greater for munmap and mprotect.
When I discuss the mm performance with Brian Makin, an engineer who worked
on performance, it was brought to my attention that such performance
benchmarks, which measuring millions of mm syscall in a tight loop, may
not accurately reflect real-world scenarios, such as that of a database
service. Also this is tested using a single HW and ChromeOS, the data
from another HW or distribution might be different. It might be best to
take this data with a grain of salt.
This patch (of 5):
Wire up mseal syscall for all architectures.

net: Add additional bit to support clockid_t timestamp type
tstamp_type is now set based on actual clockid_t compressed into 2 bits. To make the design scalable for future needs this commit bring in the change to extend the tstamp_type:1 to tstamp_type:2 to support other clockid_t timestamp. We now support CLOCK_TAI as part of tstamp_type as part of this commit with existing support CLOCK_MONOTONIC and CLOCK_REALTIME.

Powering the machine back up is like losing a bunch of DIMMs. While there would be ways to add limited support, suspend+resume is more commonly used for VMs and "easier" to support cleanly. s2idle can be supported without any device dependencies. Similarly, one would expect suspend-to-ram (i.e., S3) to work out of the box. However, QEMU currently unplugs all device memory when resuming the VM, using a cold reset on the "wakeup" path. In order to support S3, we need a feature flag for the device to tell us if memory remains plugged when waking up. In the future, QEMU will implement this feature. So let's always support s2idle and support S3 with plugged memory only if the device indicates support. Block hibernation early using the PM notifier. Trying to hibernate now fails early: # echo disk > /sys/power/state [ 26.455369] PM: hibernation: hibernation entry [ 26.458271] virtio_mem virtio0: hibernation is not supported.

drm/xe/uapi: Expose the L3 bank mask
The L3 bank mask is already generated and stored internally with
the rest of the GT topology. In user space, the compute runtime
now needs this information to be added to the device properties
therefore the topology mask query is extended to provide a new
mask which represents the L3 banks enabled on the GT.
The changes in the compute runtime are ready and approved, see
link below.

drm/v3d: Deprecate the use of the Performance Counters enum
The Performance Counters enum used to identify the index of each performance counter and provide the total number of performance counters (V3D_PERFCNT_NUM). But, this enum is only valid for V3D 4.2, not for V3D 7.1. As we implemented a new flexible structure to retrieve performance counters information, we can deprecate this enum.

drm/v3d: Create new IOCTL to expose performance counters information
Userspace usually needs some information about the performance counters available. Although we could replicate this information in the kernel and user-space, let's use the kernel as the "single source of truth" to avoid issues in the future (e.g. list of performance counters is updated in user-space, but not in the kernel, generating invalid requests). Therefore, create a new IOCTL to expose the performance counters information, that is name, category, and description.

bcachefs changes for 6.10-rc1
- More safety fixes, primarily found by syzbot - Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is primarily for testing fsck/recovery in dry run mode, so it shouldn't change anything besides disabling writes and holding dirty metadata in memory. The idea here was to reduce the amount of activity if we can't write anything out, so that bringing up a filesystem in "super ro" mode would be more lilkely to work for data recovery - but norecovery is the correct option for this. - btree_trans->locked; we now track whether a btree_trans has any btree nodes locked, and this is used for improved assertions related to trans_unlock() and trans_relock(). We'll also be using it for improving how we work with lockdep in the future: we don't want lockdep to be tracking individual btree node locks because we take too many for lockdep to track, and it's not necessary since we have a cycle detector. - Trigger improvements that are prep work for online fsck - BTREE_TRIGGER_check_repair; this regularizes how we do some repair work for extents that goes with running triggers in fsck, and fixes some subtle issues with transaction restarts there. - bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot equivalence classes are for when snapshot deletion leaves behind redundant snapshot nodes, but snapshot deletion now cleans this up right away, so the abstraction doesn't need to leak. - Improvements to how we resume writing to the journal in recovery. The code for picking the new place to write when reading the journal is greatly simplified and we also store the position in the superblock for when we don't read the journal; this means that we preserve more of the journal for list_journal debugging. - Improvements to sysfs btree_cache and btree_node_cache, for debugging memory reclaim. - We now detect when we've blocked for 10 seconds on the allocator in the write path and dump some useful info. - Safety fixes for devices references: this is a big series that changes almost all device lookups to properly check if the device exists and take a reference to it. Previously we assumed that if a bkey exists that references a device then the device must exist, and this was enforced in .invalid methods, but this was incorrect because it meant device removal relied on accounting being correct to not leave keys pointing to invalid devices, and that's not something we can assume. Getting the "pointer to invalid device" checks out of our .invalid() methods fixes some long standing device removal bugs; the only outstanding bug with device removal now is a race between the discard path and deleting alloc info, which should be easily fixed. - The allocator now prefers not to expand the new member_info.btree_allocated bitmap, meaning if repair ever requires scanning for btree nodes (because of a corrupt interior nodes) we won't have to scan the whole device(s). - New coding style document, which among other things talks about the correct usage of assertions -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmZKJQgACgkQE6szbY3K bnZETg//SU9H0OHnBSMB/cteF6PKo9QR+dhT+3n+gWTxl0o/egbGTqwbzVqGtd2f J6II1BsDk8VoTOb/gFfLRShlmJfnj2jpRThU265faR/7LQYeSaqndDPkjOpTayAD Nj/DJyiSUTL753rZh3yUhOpOIHf7iapH6wuaZCPfhdfk+yvZNW8iz07JHjHLKRp8 I2cFH0r6kN916NdRkt9oDCz68WouT8eWTqwcKra04XsLEZjNJHxLpKMq4M8UdPc7 YynJPVt+aP8+VduGIq6pV8Co3afCP2oUywo11JpRmvLsw4tex/59wxOYtpMfgn6k 4H+9WqiBwkbmnLDrfFHWRameS6F/7+GRAOVuz9nkmfk61UPU15gLjSRffqZ6u2YC 7vbrXgebId/sZXtBpQd83RMMX52BnEJah0upNJ54IsSqfDYkU9lwl6CEyYpcX1hf YNBGBTbspZztc3AB13b3ow421FMhaySUg0FDmntMR9O8Z6/BXk7Ykc7b8DPEfrFs W6JY7q+ARBxr+EgFcV74fvMCf7NJTAhyv80AKryo7NFU2JZOyyaTxcTGSnolX4Mi lyHiOgicmOX+vy3vbC1dZoDcmIDJ4Uc0vixYcpKiZqxlR8XJ+wpevC50TEhxrcW+ ZO4SloQvgyjI34xu/gZgjRYb3BhXK3x+ougVFpRG8V8zQ/+ccWg= =MKrF -----END PGP SIGNATURE----- Merge tag 'bcachefs-2024-05-19' of https://evilpiepirate.org/git/bcachefs Pull bcachefs updates from Kent Overstreet: - More safety fixes, primarily found by syzbot - Run the upgrade/downgrade paths in nochnages mode.

NFSD 6.10 Release Notes
This is a light release containing mostly optimizations, code clean-
ups, and minor bug fixes. This development cycle has focused on non-
upstream kernel work:
1. Continuing to build upstream CI for NFSD, based on kdevops
2. Backporting NFSD filecache-related fixes to selected LTS kernels
One notable new feature in v6.10 NFSD is the addition of a new
netlink protocol dedicated to configuring NFSD. A new user space
tool, nfsdctl, is to be added to nfs-utils. Lots more to come here.
As always I am very grateful to NFSD contributors, reviewers,
testers, and bug reporters who participated during this cycle.

"Aside from the usual things this has an arch update for
__iowrite64_copy() used by the RDMA drivers.
This API was intended to generate large 64 byte MemWr TLPs on PCI.
These days most processors had done this by just repeating writel() in
a loop. S390 and some new ARM64 designs require a special helper to
get this to generate.

tracing ring buffer updates for v6.10:
- Add ring_buffer memory mappings The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release. It can be enabled by compiling the library with a special flag. This was used for testing applications that perform better with the buffer being mapped. Memory mapped buffers have limitations. The main one is that it can not be used with the snapshot logic. If the buffer is mapped, snapshots will be disabled. If any logic is set to trigger snapshots on a buffer, that buffer will not be allowed to be mapped. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZkYzDRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qttNAQCj3I0OpeI1vms85ShIa7Eha2qes5uC Yml2fnapkmRSwAEAp5UTGxtDctycWOk9B9PA7/oJmLgATaQwRKoEeTUwfAA= =TyEB -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing ring buffer updates from Steven Rostedt: "Add ring_buffer memory mappings.

drm/i915: Support replaying GPU hangs with captured context image
When debugging GPU hangs Mesa developers are finding it useful to replay the captured error state against the simulator. But due various simulator limitations which prevent replicating all hangs, one step further is being able to replay against a real GPU. This is almost doable today with the missing part being able to upload the captured context image into the driver state prior to executing the uploaded hanging batch and all the buffers. To enable this last part we add a new context parameter called I915_CONTEXT_PARAM_CONTEXT_IMAGE. It follows the existing SSEU configuration pattern of being able to select which context to apply against, paired with the actual image and its size. Since this is adding a new concept of debug only uapi, we hide it behind a new kconfig option and also require activation with a module parameter. Together with a warning banner printed at driver load, all those combined should be sufficient to guard against inadvertently enabling the feature. In terms of implementation we allow the legacy context set param to be used since that removes the need to record the per context data in the proto context, while still allowing flexibility of specifying context images for any context. Mesa MR using the uapi can be seen at: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27594 v2: * Fix whitespace alignment as per checkpatch. * Added warning on userspace misuse. * Rebase for extracting ce->default_state shadowing. v3: * Rebase for I915_CONTEXT_PARAM_LOW_LATENCY.

Pull CXL updates from Dave Jiang:
- Three CXL mailbox passthrough commands are added to support the
populating and clearing of vendor debug logs:
- Get Log Capabilities
- Get Supported Log Sub-List Commands
- Clear Log
- Add support of Device Phyiscal Address (DPA) to Host Physical Address
(HPA) translation for CXL events of cxl_dram and cxl_general media.
This allows user space to figure out which CXL region the event
occured via trace event.
- Connect CXL to CPER reporting.
If a device is configured for firmware first, CXL event records are
not sent directly to the host. Those records are reported through EFI
Common Platform Error Records (CPER). Add support to route the CPER
records through the CXL sub-system in order to provide DPA to HPA
translation and also event decoding and tracing. This is useful for
users to determine which system issues may correspond to specific
hardware events.
- A number of misc cleanups and fixes:
- Fix for compile warning of cxl_security_ops
- Add debug message for invalid interleave granularity
- Enhancement to cxl-test event testing
- Add dev_warn() on unsupported mixed mode decoder
- Fix use of phys_to_target_node() for x86

sound updates for 6.10-rc1
This one became bigger than usual, not in the total size but rather
containing lots of small changes all over the places. The majority of
changes are about ASoC, especially SOF / Intel stuff, and we see an
interesting work for ASoC DAPM graph visualization, while there are
many other code cleanup and refactoring, too.
Core:
- A deadlock fix at device disconnection
- A new tool dapm-graph for visualising the DAPM state
ASoC:
- Large updates throughout the Intel audio drivers
- Fixes and clarifications for the DAPM documentation
- Cleanups of accessors for driver data, module labelling, and for
constification
- Modernsation and cleanup work in the Mediatek drivers
- Several fixes and features for the DaVinci I2S driver
- New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
Rockchip RK3308 and Texas Instruments PCM6240
HD-audio:
- Cleanup for CONFIG_PM dependencies
- Cirrus HD-audio codec fixes and quirks
Others:
- Series of tree-wide fixes in Makefiles to use *-y
- Additions of missing module descriptions
- Scarlett2 USB mixer enhancements
- A series of legacy emu10k1 fixes and improvements

accel/ivpu: Add NPU profiling support
Implement time based Metric Streamer profiling UAPI. This is a generic mechanism allowing user mode tools to sample NPU metrics. These metrics are defined by the FW and transparent to the driver. The user space can check for this feature by checking DRM_IVPU_CAP_METRIC_STREAMER driver capability.

Networking changes for 6.10.
Core & protocols
----------------
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd passing
functionality. New method based on Tarjan's Strongly Connected Components
algorithm should be both faster and remove a lot of workarounds
we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP packets
and forwarding them together. Useful for small switches / routers which
lack basic checksum offload in some scenarios (e.g. PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't
use NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory accounting,
RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked,
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states.
State can be used either for input or output packet processing.
Things we sprinkled into general kernel code
--------------------------------------------
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter
---------
- Use GFP_KERNEL to clone elements, to deal better with OOM situations
and avoid failures in the .commit step.
BPF
---
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. "Session mode" is a common use-case for tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw tracepoint
programs in order to ease migration from classic to raw tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V JITs.
This allows inlining functions which need to access per-CPU state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86 instruction.
Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor process-context
bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API
----------
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line) config.
- Initial bits of a queue control API, for now allowing a single queue
to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling
-----------------
- Remove the need to create a config file to run the net forwarding tests
so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test machine).
Add a few such tests.
- Create a shared code library for writing Python tests. Expose the YAML
Netlink library from tools/ to the tests for easy Netlink access.
- Move netfilter tests under net/, extend them, separate performance tests
from correctness tests, and iron out issues found by running them
"on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF info,
TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers
-------
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application rather
than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- support multiple RSS contexts and steering traffic to them
- support XDP metadata
- make page pool allocations more NUMA aware
- Intel (100G, ice, idpf):
- extract datapath code common among Intel drivers into a library
- use fewer resources in switchdev by sharing queues with the PF
- add PFCP filter support
- add Ethernet filter support
- use a spinlock instead of HW lock in PTP clock ops
- support 5 layer Tx scheduler topology
- nVidia/Mellanox:
- 800G link modes and 100G SerDes speeds
- per-queue IRQ coalescing configuration
- Marvell Octeon:

Merge tag 'net-next-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd
passing functionality. New method based on Tarjan's Strongly
Connected Components algorithm should be both faster and remove a
lot of workarounds we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP
packets and forwarding them together. Useful for small switches /
routers which lack basic checksum offload in some scenarios (e.g.
PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't use
NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6
address labels, netdev threaded NAPI sysfs files, bonding driver's
sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics,
TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot
of the link information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory
accounting, RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2%
PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol
driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states. State can be
used either for input or output packet processing.
Things we sprinkled into general kernel code:
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter:
- Use GFP_KERNEL to clone elements, to deal better with OOM
situations and avoid failures in the .commit step.
BPF:
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function
entry and return, the entry program can decide if the return
program gets executed and the entry program can share u64 cookie
value with return program. "Session mode" is a common use-case for
tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw
tracepoint programs in order to ease migration from classic to raw
tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V
JITs. This allows inlining functions which need to access per-CPU
state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86
instruction. Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor
process-context bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto
APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API:
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by
rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line)
config.
- Initial bits of a queue control API, for now allowing a single
queue to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling:
- Remove the need to create a config file to run the net forwarding
tests so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test
machine). Add a few such tests.
- Create a shared code library for writing Python tests. Expose the
YAML Netlink library from tools/ to the tests for easy Netlink
access.
- Move netfilter tests under net/, extend them, separate performance
tests from correctness tests, and iron out issues found by running
them "on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF
info, TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers:
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application
rather than dmesg (large number of driver changes from Asbjørn
Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- support multiple RSS contexts and steering traffic to them
- support XDP metadata
- make page pool allocations more NUMA aware
- Intel (100G, ice, idpf):
- extract datapath code common among Intel drivers into a library
- use fewer resources in switchdev by sharing queues with the PF

Bluetooth: HCI: Remove HCI_AMP support
Since BT_HS has been remove HCI_AMP controllers no longer has any use so
remove it along with the capability of creating AMP controllers.
Since we no longer need to differentiate between AMP and Primary
controllers, as only HCI_PRIMARY is left, this also remove
hdev->dev_type altogether.

tracing: Allow user-space mapping of the ring-buffer
Currently, user-space extracts data from the ring-buffer via splice,
which is handy for storage or network sharing. However, due to splice
limitations, it is imposible to do real-time analysis without a copy.
A solution for that problem is to let the user-space map the ring-buffer
directly.
The mapping is exposed via the per-CPU file trace_pipe_raw. The first
element of the mapping is the meta-page. It is followed by each
subbuffer constituting the ring-buffer, ordered by their unique page ID:
* Meta-page -- include/uapi/linux/trace_mmap.h for a description
* Subbuf ID 0
* Subbuf ID 1
...
It is therefore easy to translate a subbuf ID into an offset in the
mapping:
reader_id = meta->reader->id;
reader_offset = meta->meta_page_size + reader_id * meta->subbuf_size;
When new data is available, the mapper must call a newly introduced ioctl:
TRACE_MMAP_IOCTL_GET_READER. This will update the Meta-page reader ID to
point to the next reader containing unread data.
Mapping will prevent snapshot and buffer size modifications.

ring-buffer: Introducing ring-buffer mapping functions
In preparation for allowing the user-space to map a ring-buffer, add
a set of mapping functions:
ring_buffer_{map,unmap}()
And controls on the ring-buffer:
ring_buffer_map_get_reader() /* swap reader and head */
Mapping the ring-buffer also involves:
A unique ID for each subbuf of the ring-buffer, currently they are
only identified through their in-kernel VA.
A meta-page, where are stored ring-buffer statistics and a
description for the current reader
The linear mapping exposes the meta-page, and each subbuf of the
ring-buffer, ordered following their unique ID, assigned during the
first mapping.
Once mapped, no subbuf can get in or out of the ring-buffer: the buffer
size will remain unmodified and the splice enabling functions will in
reality simply memcpy the data instead of swapping subbufs.

tcp: socket option to check for MPTCP fallback to TCP
A way for an application to know if an MPTCP connection fell back to TCP is to use getsockopt(MPTCP_INFO) and look for errors. The issue with this technique is that the same errors -- EOPNOTSUPP (IPv4) and ENOPROTOOPT (IPv6) -- are returned if there was a fallback, *or* if the kernel doesn't support this socket option. The userspace then has to look at the kernel version to understand what the errors mean. It is not clean, and it doesn't take into account older kernels where the socket option has been backported. A cleaner way would be to expose this info to the TCP socket level. In case of MPTCP socket where no fallback happened, the socket options for the TCP level will be handled in MPTCP code, in mptcp_getsockopt_sol_tcp(). If not, that will be in TCP code, in do_tcp_getsockopt(). So MPTCP simply has to set the value 1, while TCP has to set 0. If the socket option is not supported, one of these two errors will be reported: - EOPNOTSUPP (95 - Operation not supported) for MPTCP sockets - ENOPROTOOPT (92 - Protocol not available) for TCP sockets, e.g. on the socket received after an 'accept()', when the client didn't request to use MPTCP: this socket will be a TCP one, even if the listen socket was an MPTCP one. With this new option, the kernel can return a clear answer to both "Is this kernel new enough to tell me the fallback status?" and "If it is new enough, is it currently a TCP or MPTCP socket?" questions, while not breaking the previous method.

"The bulk of the changes here are related to refactoring and expanding
the KUnit tests for string helper and fortify behavior.
Some trivial strncpy replacements in fs/ were carried in my tree. Also
some fixes to SCSI string handling were carried in my tree since the
helper for those was introduce here. Beyond that, just little fixes
all around: objtool getting confused about LKDTM+KCFI, preparing for
future refactors (constification of sysctl tables, additional
__counted_by annotations), a Clang UBSAN+i386 crash fix, and adding
more options in the hardening.config Kconfig fragment.

MSG_ZEROCOPY already does this with send(2) and sendmsg(2), but the io_uring side did not. In local testing, the crossover point for send zerocopy being faster is now around 3000 byte packets, and it performs better than the sync syscall variants as well. This feature relies on a shared branch with net-next, which was pulled into both branches. - Unification of how async preparation is done across opcodes. Previously, opcodes that required extra memory for async retry would allocate that as needed, using on-stack state until that was the case. If async retry was needed, the on-stack state was adjusted appropriately for a retry and then copied to the allocated memory. This led to some fragile and ugly code, particularly for read/write handling, and made storage retries more difficult than they needed to be. Allocate the memory upfront, as it's cheap from our pools, and use that state consistently both initially and also from the retry side. - Move away from using remap_pfn_range() for mapping the rings. This is really not the right interface to use and can cause lifetime issues or leaks. Additionally, it means the ring sq/cq arrays need to be physically contigious, which can cause problems in production with larger rings when services are restarted, as memory can be very fragmented at that point. Move to using vm_insert_page(s) for the ring sq/cq arrays, and apply the same treatment to mapped ring provided buffers. This also helps unify the code we have dealing with allocating and mapping memory. Hard to see in the diffstat as we're adding a few features as well, but this kills about ~400 lines of code from the codebase as well. - Add support for bundles for send/recv. When used with provided buffers, bundles support sending or receiving more than one buffer at the time, improving the efficiency by only needing to call into the networking stack once for multiple sends or receives. - Tweaks for our accept operations, supporting both a DONTWAIT flag for skipping poll arm and retry if we can, and a POLLFIRST flag that the application can use to skip the initial accept attempt and rely purely on poll for triggering the operation. Both of these have identical flags on the receive side already. - Make the task_work ctx locking unconditional. We had various code paths here that would do a mix of lock/trylock and set the task_work state to whether or not it was locked. All of that goes away, we lock it unconditionally and get rid of the state flag indicating whether it's locked or not. The state struct still exists as an empty type, can go away in the future. - Add support for specifying NOP completion values, allowing it to be used for error handling testing. - Use set/test bit for io-wq worker flags. Not strictly needed, but also doesn't hurt and helps silence a KCSAN warning. - Cleanups for io-wq locking and work assignments, closing a tiny race where cancelations would not be able to find the work item reliably. - Misc fixes, cleanups, and improvements * tag 'for-6.10/io_uring-20240511' of git://git.kernel.dk/linux: (97 commits) io_uring: support to inject result for NOP io_uring: fail NOP if non-zero op flags is passed in io_uring/net: add IORING_ACCEPT_POLL_FIRST flag io_uring/net: add IORING_ACCEPT_DONTWAIT flag io_uring/filetable: don't unnecessarily clear/reset bitmap io_uring/io-wq: Use set_bit() and test_bit() at worker->flags io_uring/msg_ring: cleanup posting to IOPOLL vs !IOPOLL ring io_uring: Require zeroed sqe->len on provided-buffers send io_uring/notif: disable LAZY_WAKE for linked notifs io_uring/net: fix sendzc lazy wake polling io_uring/msg_ring: reuse ctx->submitter_task read using READ_ONCE instead of re-reading it io_uring/rw: reinstate thread check for retries io_uring/notif: implement notification stacking io_uring/notif: simplify io_notif_flush() net: add callback for setting a ubuf_info to skb net: extend ubuf_info callback to ops structure io_uring/net: support bundles for recv io_uring/net: support bundles for send io_uring/kbuf: add helpers for getting/peeking multiple buffers io_uring/net: add provided buffer support for IORING_OP_SEND ... |

Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual fses.
Features:
- Free up FMODE_* bits. I've freed up bits 6, 7, 8, and 24. That
means we now have six free FMODE_* bits in total (but bit #6
already got used for FMODE_WRITE_RESTRICTED)
- Add FOP_HUGE_PAGES flag (follow-up to FMODE_* cleanup)
- Add fd_raw cleanup class so we can make use of automatic cleanup
provided by CLASS(fd_raw, f)(fd) for O_PATH fds as well
- Optimize seq_puts()
- Simplify __seq_puts()
- Add new anon_inode_getfile_fmode() api to allow specifying f_mode
instead of open-coding it in multiple places
- Annotate struct file_handle with __counted_by() and use
struct_size()
- Warn in get_file() whether f_count resurrection from zero is
attempted (epoll/drm discussion)
- Folio-sophize aio
- Export the subvolume id in statx() for both btrfs and bcachefs
- Relax linkat(AT_EMPTY_PATH) requirements
- Add F_DUPFD_QUERY fcntl() allowing to compare two file descriptors
for dup*() equality replacing kcmp()
Cleanups:
- Compile out swapfile inode checks when swap isn't enabled
- Use (1 << n) notation for FMODE_* bitshifts for clarity
- Remove redundant variable assignment in fs/direct-io
- Cleanup uses of strncpy in orangefs
- Speed up and cleanup writeback
- Move fsparam_string_empty() helper into header since it's currently
open-coded in multiple places
- Add kernel-doc comments to proc_create_net_data_write()
- Don't needlessly read dentry->d_flags twice
Fixes:
- Fix out-of-range warning in nilfs2
- Fix ecryptfs overflow due to wrong encryption packet size
calculation
- Fix overly long line in xfs file_operations (follow-up to FMODE_*
cleanup)
- Don't raise FOP_BUFFER_{R,W}ASYNC for directories in xfs (follow-up
to FMODE_* cleanup)
- Don't call xfs_file_open from xfs_dir_open (follow-up to FMODE_*
cleanup)
- Fix stable offset api to prevent endless loops
- Fix afs file server rotations
- Prevent xattr node from overflowing the eraseblock in jffs2
- Move fdinfo PTRACE_MODE_READ procfs check into the .permission()
operation instead of .open() operation since this caused userspace
regressions"

used to provide a barrier between different parts of an SoC
- Lots of updates for the Qualcomm platform drivers, in particular
SCM, which gets a rewrite of its initialization code
- Firmware driver updates for Arm FF-A notification interrupts
and indirect messaging, SCMI firmware support for pin control
and vendor specific interfaces, and TEE firmware interface
changes across multiple TEE drivers
- A larger cleanup of the Mediatek CMDQ driver and some related bits
- Kconfig changes for riscv drivers to prepare for adding Kanaan
k230 support
- Multiple minor updates for the TI sysc bus driver, memory controllers,
hisilicon hccs and more

drm/panthor: Relax the constraints on the tiler chunk size
The field used to store the chunk size if 12 bits wide, and the encoding
is chunk_size = chunk_header.chunk_size << 12, which gives us a
theoretical [4k:8M] range. This range is further limited by
implementation constraints, and all known implementations seem to
impose a [128k:8M] range, so do the same here.
We also relax the power-of-two constraint, which doesn't seem to
exist on v10. This will allow userspace to fine-tune initial/max
tiler memory on memory-constrained devices.
v4:
- Actually fix the range in the kerneldoc
v3:
- Add R-bs
- Fix valid range in the kerneldoc
v2:
- Turn the power-of-two constraint into a page-aligned constraint to allow
fine-tune of the initial/max heap memory size
- Fix the panthor_heap_create() kerneldoc

landlock: Add IOCTL access right for character and block devices
Introduces the LANDLOCK_ACCESS_FS_IOCTL_DEV right and increments the Landlock ABI version to 5. This access right applies to device-custom IOCTL commands when they are invoked on block or character device files. Like the truncate right, this right is associated with a file descriptor at the time of open(2), and gets respected even when the file descriptor is used outside of the thread which it was originally opened in. Therefore, a newly enabled Landlock policy does not apply to file descriptors which are already open. If the LANDLOCK_ACCESS_FS_IOCTL_DEV right is handled, only a small number of safe IOCTL commands will be permitted on newly opened device files. These include FIOCLEX, FIONCLEX, FIONBIO and FIOASYNC, as well as other IOCTL commands for regular files which are implemented in fs/ioctl.c. Noteworthy scenarios which require special attention: TTY devices are often passed into a process from the parent process, and so a newly enabled Landlock policy does not retroactively apply to them automatically. In the past, TTY devices have often supported IOCTL commands like TIOCSTI and some TIOCLINUX subcommands, which were letting callers control the TTY input buffer (and simulate keypresses). This should be restricted to CAP_SYS_ADMIN programs on modern kernels though. Known limitations: The LANDLOCK_ACCESS_FS_IOCTL_DEV access right is a coarse-grained control over IOCTL commands. Landlock users may use path-based restrictions in combination with their knowledge about the file system layout to control what IOCTLs can be done.

Patch #2 deals with GTP extension headers. This variable length extension header to decapsulate packets accordingly. Otherwise, packets are dropped when these extension headers are present which breaks interoperation with other non-Linux based GTP implementations. Patch #3 prepares for IPv6 support by moving IPv4 specific fields in PDP context objects to a union. Patch #4 adds IPv6 support while retaining backward compatibility. Three new attributes allows to declare an IPv6 GTP tunnel GTPA_FAMILY, GTPA_PEER_ADDR6 and GTPA_MS_ADDR6 as well as IFLA_GTP_LOCAL6 to declare the IPv6 GTP UDP socket. Up to this patch, only IPv6 outer in IPv6 inner is supported. Patch #5 uses IPv6 address /64 prefix for UE/MS in the inner headers. Unlike IPv4, which provides a 1:1 mapping between UE/MS, IPv6 tunnel encapsulates traffic for /64 address as specified by 3GPP TS. Patch has been split from Patch #4 to highlight this behaviour. Patch #6 passes up IPv6 link-local traffic, such as IPv6 SLAAC, for handling to userspace so they are handled as control packets. Patch #7 prepares to allow for GTP IPv4 over IPv6 and vice-versa by moving IP specific debugging out of the function to build IPv4 and IPv6 GTP packets. Patch #8 generalizes TOS/DSCP handling following similar approach as in the existing iptunnel infrastructure. Patch #9 adds a helper function to build an IPv4 GTP packet in the outer header. Patch #10 adds a helper function to build an IPv6 GTP packet in the outer header. Patch #11 adds support for GTP IPv4-over-IPv6 and vice-versa. Patch #12 allows to use the same TID/TEID (tunnel identifier) for inner IPv4 and IPv6 packets for better UE/MS dual stack integration. This series integrates with the osmocom.org project CI and TTCN-3 test infrastructure (Oliver Smith) as well as the userspace libgtpnl library.

fcntl: add F_DUPFD_QUERY fcntl()
Often userspace needs to know whether two file descriptors refer to the
same struct file. For example, systemd uses this to filter out duplicate
file descriptors in it's file descriptor store (cf. [1]) and vulkan uses
it to compare dma-buf fds (cf. [2]).
The only api we provided for this was kcmp() but that's not generally
available or might be disallowed because it is way more powerful (allows
ordering of file pointers, operates on non-current task) etc. So give
userspace a simple way of comparing two file descriptors for sameness
adding a new fcntl() F_DUDFD_QUERY.

io_uring/net: add IORING_ACCEPT_POLL_FIRST flag
Similarly to how polling first is supported for receive, it makes sense to provide the same for accept. An accept operation does a lot of expensive setup, like allocating an fd, a socket/inode, etc. If no connection request is already pending, this is wasted and will just be cleaned up and freed, only to retry via the usual poll trigger. Add IORING_ACCEPT_POLL_FIRST, which tells accept to only initiate the accept request if poll says we have something to accept. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

PCI/CXL: Fail bus reset if upstream CXL Port has SBR masked
Per CXL spec r3.1, sec 8.1.5.2, the Secondary Bus Reset (SBR) bit in the Bridge Control register of a CXL port has no effect unless the "Unmask SBR" bit is set. Return -ENOTTY if we attempt a bus reset on a device below a CXL Port where "Unmask SBR" is 0. Otherwise, the bus reset would appear to have succeeded even though setting the bridge SBR bit had no effect.

If none of these attributes are specified, default is still to IPv4 INADDR_ANY for backward compatibility. Add new attributes to set up family and IPv6 address of GTP tunnels: GTPA_FAMILY, GTPA_PEER_ADDR6 and GTPA_MS_ADDR6. If no GTPA_FAMILY is specified, AF_INET is assumed for backward compatibility. setsockopt IPV6_ADDRFORM allows to downgrade socket from IPv6 to IPv4 after socket is bound. Assumption is that socket listener that is attached to the gtp device needs to be either IPv4 or IPv6. Therefore, GTP socket listener does not allow for IPv4-mapped-IPv6 listener.

powerpc/dexcr: Add DEXCR prctl interface
Now that we track a DEXCR on a per-task basis, individual tasks are free to configure it as they like. The interface is a pair of getter/setter prctl's that work on a single aspect at a time (multiple aspects at once is more difficult if there are different rules applied for each aspect, now or in future). The getter shows the current state of the process config, and the setter allows setting/clearing the aspect.

netfilter: conntrack: fix ct-state for ICMPv6 Multicast Router Discovery
So far Multicast Router Advertisements and Multicast Router Solicitations from the Multicast Router Discovery protocol (RFC4286) would be marked as INVALID for IPv6, even if they are in fact intact and adhering to RFC4286. This broke MRA reception and by that multicast reception on IPv6 multicast routers in a Proxmox managed setup, where Proxmox would install a rule like "-m conntrack --ctstate INVALID -j DROP" at the top of the FORWARD chain with br-nf-call-ip6tables enabled by default. Similar to as it's done for MLDv1, MLDv2 and IPv6 Neighbor Discovery already, fix this issue by excluding MRD from connection tracking handling as MRD always uses predefined multicast destinations for its messages, too. This changes the ct-state for ICMPv6 MRD messages from INVALID to UNTRACKED. This issue was found and fixed with the help of the mrdisc tool (https://github.com/troglobit/mrdisc).

Merge tag 'drm-intel-gt-next-2024-04-26' of https://anongit.freedesktop.org/git/drm/drm-intel into drm-next
UAPI Changes:
- drm/i915/guc: Use context hints for GT frequency
Allow user to provide a low latency context hint. When set, KMD
sends a hint to GuC which results in special handling for this
context. SLPC will ramp the GT frequency aggressively every time
it switches to this context. The down freq threshold will also be
lower so GuC will ramp down the GT freq for this context more slowly.
We also disable waitboost for this context as that will interfere with
the strategy.
We need to enable the use of SLPC Compute strategy during init, but
it will apply only to contexts that set this bit during context
creation.
Userland can check whether this feature is supported using a new param-
I915_PARAM_HAS_CONTEXT_FREQ_HINT. This flag is true for all guc submission
enabled platforms as they use SLPC for frequency management.
The Mesa usage model for this flag is here -
https://gitlab.freedesktop.org/sushmave/mesa/-/commits/compute_hint
- drm/i915/gt: Enable only one CCS for compute workload
Enable only one CCS engine by default with all the compute sices
allocated to it.
While generating the list of UABI engines to be exposed to the
user, exclude any additional CCS engines beyond the first
instance
***
NOTE: This W/A will make all DG2 SKUs appear like single CCS SKUs by
default to mitigate a hardware bug. All the EUs will still remain
usable, and all the userspace drivers have been confirmed to be able
to dynamically detect the change in number of CCS engines and adjust.
For the smaller percent of applications that get perf benefit from
letting the userspace driver dispatch across all 4 CCS engines we will
be introducing a sysfs control as a later patch to choose 4 CCS each
with 25% EUs (or 50% if 2 CCS).
NOTE: A regression has been reported at
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/10895
However Andi has been triaging the issue and we're closing in a fix
to the gap in the W/A implementation:

TEE driver for Trusted Services
This introduces a TEE driver for Trusted Services [1]. Trusted Services is a TrustedFirmware.org project that provides a framework for developing and deploying device Root of Trust services in FF-A [2] Secure Partitions. The project hosts the reference implementation of Arm Platform Security Architecture [3] for Arm A-profile devices. The FF-A Secure Partitions are accessible through the FF-A driver in Linux.

media: v4l: subdev: Add len_routes field to struct v4l2_subdev_routing
The len_routes field is used to tell the size of the routes array in struct v4l2_subdev_routing. This way the number of routes returned from S_ROUTING IOCTL may be larger than the number of routes provided, in case there are more routes returned by the driver. Note that this uAPI is still disabled in the code, so this change can safely be done. Anyone who manually patched the code to enable this uAPI must update their code. The patch also increases the number of reserved fields in struct v4l2_subdev_routing.

media: v4l: Support line-based metadata capture
Many camera sensors, among other devices, transmit embedded data and image data for each CSI-2 frame. This embedded data typically contains register configuration of the sensor that has been used to capture the image data of the same frame. The embedded data is received by the CSI-2 receiver and has the same properties as the image data, including that it is line based: it has width, height and bytesperline (stride). Add these fields to struct v4l2_meta_format and document them. Also add V4L2_FMT_FLAG_META_LINE_BASED to tell a given format is line-based i.e. these fields of struct v4l2_meta_format are valid for it.

media: uapi: v4l: Add generic 8-bit metadata format definitions
Generic 8-bit metadata formats define the in-memory data layout but not the format of the data itself. The reasoning for having such formats is to allow CSI-2 receiver drivers to receive and DMA drivers to write the data to memory without knowing a large number of device-specific formats. These formats may be used only in conjunction with a Media Controller pipeline where the internal pad of the source sub-device defines the specific format of the data (using an mbus code).

media: uapi: Add generic serial metadata mbus formats
Add generic serial metadata mbus formats. These formats describe data width and packing but not the content itself. The reason for specifying such formats is that the formats as such are fairly device specific but they are still handled by CSI-2 receiver drivers that should not be aware of device specific formats. What makes generic metadata formats possible is that these formats are parsed by software only, after capturing the data to system memory. Also add a definition for "Data Unit" to cover what is essentially a pixel but is not image data.

bpf: add mrtt and srtt as BPF_SOCK_OPS_RTT_CB args
Two important arguments in RTT estimation, mrtt and srtt, are passed to tcp_bpf_rtt(), so that bpf programs get more information about RTT computation in BPF_SOCK_OPS_RTT_CB. The difference between bpf_sock_ops->srtt_us and the srtt here is: the former is an old rtt before update, while srtt passed by tcp_bpf_rtt() is that after update.

powerpc/papr_scm: Move duplicate definitions to common header files
papr_scm and ndtest share common PDSM payload structs like nd_papr_pdsm_health. Presently these structs are duplicated across papr_pdsm.h and ndtest.h header files. Since 'ndtest' is essentially arch independent and can run on platforms other than PPC64, a way needs to be deviced to avoid redundancy and duplication of PDSM structs in future. So the patch proposes moving the PDSM header from arch/powerpc/include- -/uapi/ to the generic include/uapi/linux directory. Also, there are some #defines common between papr_scm and ndtest which are not exported to the user space. So, move them to a header file which can be shared across ndtest and papr_scm via newly introduced include/linux/papr_scm.h.

scsi: mpi3mr: Fix some kernel-doc warnings in scsi_bsg_mpi3mr.h
Correct the name of a struct in kernel-doc to match the actual function name. Add kernel-doc comments for 2 reserved fields to match comments for other reserved fields. Correct the kernel-doc comments for a nested struct to eliminate kernel-doc warnings for them. Warnings fixed here are: scsi_bsg_mpi3mr.h:419: warning: expecting prototype for struct mpi3mr_bsg_buf_entry_list. Prototype was for struct mpi3mr_buf_entry_list instead scsi_bsg_mpi3mr.h:435: warning: Function parameter or struct member 'rsvd2' not described in 'mpi3mr_bsg_mptcmd' scsi_bsg_mpi3mr.h:456: warning: Function parameter or struct member 'rsvd3' not described in 'mpi3mr_bsg_packet' scsi_bsg_mpi3mr.h:456: warning: Excess struct member 'drvrcmd' description in 'mpi3mr_bsg_packet' scsi_bsg_mpi3mr.h:456: warning: Excess struct member 'mptcmd' description in 'mpi3mr_bsg_packet' Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Link: https://lore.kernel.org/r/20240424055322.1400-1-rdunlap@infradead.org Cc: James E.J.

io_uring/net: support bundles for recv
If IORING_OP_RECV is used with provided buffers, the caller may also set IORING_RECVSEND_BUNDLE to turn it into a multi-buffer recv. This grabs buffers available and receives into them, posting a single completion for all of it. This can be used with multishot receive as well, or without it. Now that both send and receive support bundles, add a feature flag for it as well. If IORING_FEAT_RECVSEND_BUNDLE is set after registering the ring, then the kernel supports bundles for recv and send. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

io_uring/net: support bundles for send
If IORING_OP_SEND is used with provided buffers, the caller may also set IORING_RECVSEND_BUNDLE to turn it into a multi-buffer send. The idea is that an application can fill outgoing buffers in a provided buffer group, and then arm a single send that will service them all. Once there are no more buffers to send, or if the requested length has been sent, the request posts a single completion for all the buffers. This only enables it for IORING_OP_SEND, IORING_OP_SENDMSG is coming in a separate patch. However, this patch does do a lot of the prep work that makes wiring up the sendmsg variant pretty trivial. They share the prep side. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

ethtool: Expand Ethernet Power Equipment with c33 (PoE) alongside PoDL
In the current PSE interface for Ethernet Power Equipment, support is limited to PoDL. This patch extends the interface to accommodate the objects specified in IEEE 802.3-2022 145.2 for Power sourcing Equipment (PSE). The following objects are now supported and considered mandatory: - IEEE 802.3-2022 30.9.1.1.5 aPSEPowerDetectionStatus - IEEE 802.3-2022 30.9.1.1.2 aPSEAdminState - IEEE 802.3-2022 30.9.1.2.1 aPSEAdminControl To avoid confusion between "PoDL PSE" and "PoE PSE", which have similar names but distinct values, we have followed the suggestion of Oleksij Rempel and Andrew Lunn to maintain separate naming schemes for each, using c33 (clause 33) prefix for "PoE PSE".

udpencap: Remove Obsolete UDP_ENCAP_ESPINUDP_NON_IKE Support
The UDP_ENCAP_ESPINUDP_NON_IKE mode, introduced into the Linux kernel in 2004 [2], has remained inactive and obsolete for an extended period. This mode was originally defined in an early version of an IETF draft [1] from 2001. By the time it was integrated into the kernel in 2004 [2], it had already been replaced by UDP_ENCAP_ESPINUDP [3] in later versions of draft-ietf-ipsec-udp-encaps, particularly in version 06. Over time, UDP_ENCAP_ESPINUDP_NON_IKE has lost its relevance, with no known use cases. With this commit, we remove support for UDP_ENCAP_ESPINUDP_NON_IKE, simplifying the codebase and eliminating unnecessary complexity. Kernel will return an error -ENOPROTOOPT if the userspace tries to set this option.

drm: Introduce plane SIZE_HINTS property
Add a new immutable plane property by which a plane can advertise a handful of recommended plane sizes. This would be mostly exposed by cursor planes as a slightly more capable replacement for the DRM_CAP_CURSOR_WIDTH/HEIGHT caps, which can only declare a one size fits all limit for the whole device. Currently eg. amdgpu/i915/nouveau just advertize the max cursor size via the cursor size caps. But always using the max sized cursor can waste a surprising amount of power, so a better strategy is desirable. Most other drivers don't specify any cursor size at all, in which case the ioctl code just claims that 64x64 is a great choice. Whether that is actually true is debatable. A poll of various compositor developers informs us that blindly probing with setcursor/atomic ioctl to determine suitable cursor sizes is not acceptable, thus the introduction of the new property to supplant the cursor size caps. The compositor will now be free to select a more optimal cursor size from the short list of options. Note that the reported sizes (either via the property or the caps) make no claims about things such as plane scaling. So these things should only really be consulted for simple "cursor like" use cases. Userspace consumer in the form of mutter seems ready: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3165 v2: Try to add some docs v3: Specify that value 0 is reserved for future use (basic idea from Jonas) Drop the note about typical hardware (Pekka) v4: Update the docs to indicate the list is "in order of preference" Add a a link to the mutter MR v5: Limit to cursors only for now (Simon) Cc: Jonas Ådahl <jadahl@redhat.com> Cc: Sameer Lattannavar <sameer.lattannavar@intel.com> Reviewed-by: Sebastian Wick <sebastian.wick@redhat.com> Reviewed-by: Simon Ser <contact@emersion.fr> Acked-by: Daniel Stone <daniels@collabora.com> Acked-by: Harry Wentland <harry.wentland@amd.com> Acked-by: Pekka Paalanen <pekka.paalanen@collabora.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240318204408.9687-2-ville.syrjala@linux.intel.com |

mptcp: add last time fields in mptcp_info
This patch adds "last time" fields last_data_sent, last_data_recv and last_ack_recv in struct mptcp_sock to record the last time data_sent, data_recv and ack_recv happened. They all are initialized as tcp_jiffies32 in __mptcp_init_sock(), and updated as tcp_jiffies32 too when data is sent in __subflow_push_pending(), data is received in __mptcp_move_skbs_from_subflow(), and ack is received in ack_update_msk(). Similar to tcpi_last_data_sent, tcpi_last_data_recv and tcpi_last_ack_recv exposed with TCP, this patch exposes the last time "an action happened" for MPTCP in mptcp_info, named mptcpi_last_data_sent, mptcpi_last_data_recv and mptcpi_last_ack_recv, calculated in mptcp_diag_fill_info() as the time deltas between now and the newly added last time fields in mptcp_sock. Since msk->last_ack_recv needs to be protected by mptcp_data_lock/unlock, and lock_sock_fast can sleep and be quite slow, move the entire mptcp_data_lock/unlock block after the lock/unlock_sock_fast block. Then mptcpi_last_data_sent and mptcpi_last_data_recv are set in lock/unlock_sock_fast block, while mptcpi_last_ack_recv is set in mptcp_data_lock/unlock block, which is protected by a spinlock and should not block for too long. Also add three reserved bytes in struct mptcp_info not to have holes in this structure exposed to userspace.

ntsync: Introduce NTSYNC_IOC_CREATE_SEM.
This corresponds to the NT syscall NtCreateSemaphore(). Semaphores are one of three types of object to be implemented in this driver, the others being mutexes and events. An NT semaphore contains a 32-bit counter, and is signaled and can be acquired when the counter is nonzero. The counter has a maximum value which is specified at creation time. The initial value of the semaphore is also specified at creation time. There are no restrictions on the maximum and initial value. Each object is exposed as an file, to which any number of fds may be opened. When all fds are closed, the object is deleted. Objects hold a pointer to the ntsync_device that created them. The device's reference count is driven by struct file.

net: phy: Introduce ethernet link topology representation
Link topologies containing multiple network PHYs attached to the same net_device can be found when using a PHY as a media converter for use with an SFP connector, on which an SFP transceiver containing a PHY can be used. With the current model, the transceiver's PHY can't be used for operations such as cable testing, timestamping, macsec offload, etc. The reason being that most of the logic for these configuration, coming from either ethtool netlink or ioctls tend to use netdev->phydev, which in multi-phy systems will reference the PHY closest to the MAC. Introduce a numbering scheme allowing to enumerate PHY devices that belong to any netdev, which can in turn allow userspace to take more precise decisions with regard to each PHY's configuration. The numbering is maintained per-netdev, in a phy_device_list. The numbering works similarly to a netdevice's ifindex, with identifiers that are only recycled once INT_MAX has been reached. This prevents races that could occur between PHY listing and SFP transceiver removal/insertion. The identifiers are assigned at phy_attach time, as the numbering depends on the netdevice the phy is attached to. The PHY index can be re-used for PHYs that are persistent.

ethtool: add interface to read Tx hardware timestamping statistics
Multiple network devices that support hardware timestamping appear to have common behavior with regards to timestamp handling. Implement common Tx hardware timestamping statistics in a tx_stats struct_group. Common Rx hardware timestamping statistics can subsequently be implemented in a rx_stats struct_group for ethtool_ts_stats.

ASoC: Intel: avs: Fixes and cleanups for 6.10
Merge series from Cezary Rojewski <cezary.rojewski@intel.com>: Set of changes targeting the avs-driver only. No new features, patchset either fixes or fortifies existing code. Patchset starts off with a fix for debugbility on ICL+ platforms which I have forgotten to fixup when providing support for these initially. The next two address copier module initialization, most importantly, silence the gcc 'field-spanning write' false-positive. The following four: 6/13 ASoC: Intel: avs: Replace risky functions with safer variants 7/13 ASoC: Intel: avs: Fix potential integer overflow 8/13 ASoC: Intel: avs: Test result of avs_get_module_entry() 9/13 ASoC: Intel: avs: Remove dead code address problems found out by Coverity static analysis tool. The last two worth mentioning are: recommendation from the firmware team to wake subsystem from D0ix when starting any pipeline -and- shielding against invalid period/buffer sizes. Audio format shall be taken into consideration when calculating either of these.

net: ethtool: Add impedance mismatch result code to cable test
Some PHYs can recognize during a cable test if the impedance in the cable is okay. They can detect reflections caused by impedance discontinuity between a regular 100 Ohm cable and an abnormal part with a higher or lower impedance. This commit introduces a new result code: ETHTOOL_A_CABLE_RESULT_CODE_IMPEDANCE_MISMATCH, which represents the results of a cable test indicating issues with impedance integrity.

tee: tstee: Add Trusted Services TEE driver
The Trusted Services project provides a framework for developing and deploying device Root of Trust services in FF-A Secure Partitions. The FF-A SPs are accessible through the FF-A driver, but this doesn't provide a user space interface. The goal of this TEE driver is to make Trusted Services SPs accessible for user space clients. All TS SPs have the same FF-A UUID, it identifies the RPC protocol used by TS. A TS SP can host one or more services, a service is identified by its service UUID. The same type of service cannot be present twice in the same SP. During SP boot each service in an SP is assigned an interface ID, this is just a short ID to simplify message addressing. There is 1:1 mapping between TS SPs and TEE devices, i.e. a separate TEE device is registered for each TS SP. This is required since contrary to the generic TEE design where memory is shared with the whole TEE implementation, in case of FF-A, memory is shared with a specific SP. A user space client has to be able to separately share memory with each SP based on its endpoint ID.

crypto: remove CONFIG_CRYPTO_STATS
Remove support for the "Crypto usage statistics" feature (CONFIG_CRYPTO_STATS). This feature does not appear to have ever been used, and it is harmful because it significantly reduces performance and is a large maintenance burden. Covering each of these points in detail: 1. Feature is not being used Since these generic crypto statistics are only readable using netlink, it's fairly straightforward to look for programs that use them. I'm unable to find any evidence that any such programs exist. For example, Debian Code Search returns no hits except the kernel header and kernel code itself and translations of the kernel header: https://codesearch.debian.net/search?q=CRYPTOCFGA_STAT&literal=1&perpkg=1 The patch series that added this feature in 2018 (https://lore.kernel.org/linux-crypto/1537351855-16618-1-git-send-email-clabbe@baylibre.com/) said "The goal is to have an ifconfig for crypto device." This doesn't appear to have happened. It's not clear that there is real demand for crypto statistics. Just because the kernel provides other types of statistics such as I/O and networking statistics and some people find those useful does not mean that crypto statistics are useful too. Further evidence that programs are not using CONFIG_CRYPTO_STATS is that it was able to be disabled in RHEL and Fedora as a bug fix (https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/2947). Even further evidence comes from the fact that there are and have been bugs in how the stats work, but they were never reported. For example, before Linux v6.7 hash stats were double-counted in most cases. There has also never been any documentation for this feature, so it might be hard to use even if someone wanted to. 2. CONFIG_CRYPTO_STATS significantly reduces performance Enabling CONFIG_CRYPTO_STATS significantly reduces the performance of the crypto API, even if no program ever retrieves the statistics. This primarily affects systems with a large number of CPUs. For example, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2039576 reported that Lustre client encryption performance improved from 21.7GB/s to 48.2GB/s by disabling CONFIG_CRYPTO_STATS. It can be argued that this means that CONFIG_CRYPTO_STATS should be optimized with per-cpu counters similar to many of the networking counters. But no one has done this in 5+ years. This is consistent with the fact that the feature appears to be unused, so there seems to be little interest in improving it as opposed to just disabling it. It can be argued that because CONFIG_CRYPTO_STATS is off by default, performance doesn't matter. But Linux distros tend to error on the side of enabling options. The option is enabled in Ubuntu and Arch Linux, and until recently was enabled in RHEL and Fedora (see above). So, even just having the option available is harmful to users. 3. CONFIG_CRYPTO_STATS is a large maintenance burden There are over 1000 lines of code associated with CONFIG_CRYPTO_STATS, spread among 32 files. It significantly complicates much of the implementation of the crypto API. After the initial submission, many fixes and refactorings have consumed effort of multiple people to keep this feature "working". We should be spending this effort elsewhere.

ip_tunnel: convert __be16 tunnel flags to bitmaps
Historically, tunnel flags like TUNNEL_CSUM or TUNNEL_ERSPAN_OPT have been defined as __be16. Now all of those 16 bits are occupied and there's no more free space for new flags. It can't be simply switched to a bigger container with no adjustments to the values, since it's an explicit Endian storage, and on LE systems (__be16)0x0001 equals to (__be64)0x0001000000000000. We could probably define new 64-bit flags depending on the Endianness, i.e. (__be64)0x0001 on BE and (__be64)0x00010000... on LE, but that would introduce an Endianness dependency and spawn a ton of Sparse warnings. To mitigate them, all of those places which were adjusted with this change would be touched anyway, so why not define stuff properly if there's no choice. Define IP_TUNNEL_*_BIT counterparts as a bit number instead of the value already coded and a fistful of <16 <-> bitmap> converters and helpers. The two flags which have a different bit position are SIT_ISATAP_BIT and VTI_ISVTI_BIT, as they were defined not as __cpu_to_be16(), but as (__force __be16), i.e. had different positions on LE and BE. Now they both have strongly defined places. Change all __be16 fields which were used to store those flags, to IP_TUNNEL_DECLARE_FLAGS() -> DECLARE_BITMAP(__IP_TUNNEL_FLAG_NUM) -> unsigned long[1] for now, and replace all TUNNEL_* occurrences to their bitmap counterparts. Use the converters in the places which talk to the userspace, hardware (NFP) or other hosts (GRE header). The rest must explicitly use the new flags only. This must be done at once, otherwise there will be too many conversions throughout the code in the intermediate commits. Finally, disable the old __be16 flags for use in the kernel code (except for the two 'irregular' flags mentioned above), to prevent any accidental (mis)use of them. For the userspace, nothing is changed, only additions were made. Most noticeable bloat-o-meter difference (.text): vmlinux: 307/-1 (306) gre.ko: 62/0 (62) ip_gre.ko: 941/-217 (724) [*] ip_tunnel.ko: 390/-900 (-510) [**] ip_vti.ko: 138/0 (138) ip6_gre.ko: 534/-18 (516) [*] ip6_tunnel.ko: 118/-10 (108) [*] gre_flags_to_tnl_flags() grew, but still is inlined [**] ip_tunnel_find() got uninlined, hence such decrease The average code size increase in non-extreme case is 100-200 bytes per module, mostly due to sizeof(long) > sizeof(__be16), as %__IP_TUNNEL_FLAG_NUM is less than %BITS_PER_LONG and the compilers are able to expand the majority of bitmap_*() calls here into direct operations on scalars.

SCSI fixes on 20240330
Fully half this pull is updates to lpfc and qla2xxx which got committed just as the merge window opened. A sizeable fraction of the driver updates are simple bug fixes (and lock reworks for bug fixes in the case of lpfc), so rather than splitting the few actual enhancements out, we're just adding the drivers to the -rc1 pull. The enhancements for lpfc are log message removals, copyright updates and three patches redefining types. For qla2xxx it's just removing a debug message on module removal and the manufacturer detail update. The two major fixes are the sg teardown race and a core error leg problem with the procfs directory not being removed if we destroy a created host that never got to the running state.

drm/xe/uapi: Define topology types as indexes rather than masks
The topology type is an index (not a mask) so define the values like other indexes instead of using powers of 2. This is also to make clear that the next type can use value 3. This commit does not change the existing values so it does not break compatibility.

scsi: mpi3mr: Avoid memcpy field-spanning write WARNING
When the "storcli2 show" command is executed for eHBA-9600, mpi3mr driver prints this WARNING message: memcpy: detected field-spanning write (size 128) of single field "bsg_reply_buf->reply_buf" at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 (size 1) WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr] The cause of the WARN is 128 bytes memcpy to the 1 byte size array "__u8 replay_buf[1]" in the struct mpi3mr_bsg_in_reply_buf. The array is intended to be a flexible length array, so the WARN is a false positive. To suppress the WARN, remove the constant number '1' from the array declaration and clarify that it has flexible length. Also, adjust the memory allocation size to match the change.

Prototype was for enum plink_actions instead This is because the documentation doesn't match the code. Normally the correct fix for such an issue is to modify the documentation to match the code.

Tracing updates for 6.9:
Main user visible change:
- User events can now have "multi formats"
The current user events have a single format. If another event is created
with a different format, it will fail to be created. That is, once an
event name is used, it cannot be used again with a different format. This
can cause issues if a library is using an event and updates its format.
An application using the older format will prevent an application using
the new library from registering its event.
A task could also DOS another application if it knows the event names, and
it creates events with different formats.
The multi-format event is in a different name space from the single
format. Both the event name and its format are the unique identifier.
This will allow two different applications to use the same user event name
but with different payloads.
- Added support to have ftrace_dump_on_oops dump out instances and
not just the main top level tracing buffer.
Other changes:
- Add eventfs_root_inode
Only the root inode has a dentry that is static (never goes away) and
stores it upon creation. There's no reason that the thousands of other
eventfs inodes should have a pointer that never gets set in its
descriptor. Create a eventfs_root_inode desciptor that has a eventfs_inode
descriptor and a dentry pointer, and only the root inode will use this.
- Added WARN_ON()s in eventfs
There's some conditionals remaining in eventfs that should never be hit,
but instead of removing them, add WARN_ON() around them to make sure that
they are never hit.
- Have saved_cmdlines allocation also include the map_cmdline_to_pid array
The saved_cmdlines structure allocates a large amount of data to hold its
mappings. Within it, it has three arrays. Two are already apart of it:
map_pid_to_cmdline[] and saved_cmdlines[]. More memory can be saved by
also including the map_cmdline_to_pid[] array as well.
- Restructure __string() and __assign_str() macros used in TRACE_EVENT().
Dynamic strings in TRACE_EVENT() are declared with:
__string(name, source)
And assigned with:
__assign_str(name, source)
In the tracepoint callback of the event, the __string() is used to get the
size needed to allocate on the ring buffer and __assign_str() is used to
copy the string into the ring buffer. There's a helper structure that is
created in the TRACE_EVENT() macro logic that will hold the string length
and its position in the ring buffer which is created by __string().
There are several trace events that have a function to create the string
to save. This function is executed twice. Once for __string() and again
for __assign_str(). There's no reason for this. The helper structure could
also save the string it used in __string() and simply copy that into
__assign_str() (it also already has its length).
By using the structure to store the source string for the assignment, it
means that the second argument to __assign_str() is no longer needed.
It will be removed in the next merge window, but for now add a warning if
the source string given to __string() is different than the source string
given to __assign_str(), as the source to __assign_str() isn't even used
and will be going away.
- Added checks to make sure that the source of __string() is also the
source of __assign_str() so that it can be safely removed in the next
merge window.
Included fixes that the above check found.
- Other minor clean ups and fixes

tracing/user_events: Introduce multi-format events
Currently user_events supports 1 event with the same name and must have
the exact same format when referenced by multiple programs. This opens
an opportunity for malicious or poorly thought through programs to
create events that others use with different formats. Another scenario
is user programs wishing to use the same event name but add more fields
later when the software updates. Various versions of a program may be
running side-by-side, which is prevented by the current single format
requirement.
Add a new register flag (USER_EVENT_REG_MULTI_FORMAT) which indicates
the user program wishes to use the same user_event name, but may have
several different formats of the event. When this flag is used, create
the underlying tracepoint backing the user_event with a unique name
per-version of the format. It's important that existing ABI users do
not get this logic automatically, even if one of the multi format
events matches the format. This ensures existing programs that create
events and assume the tracepoint name will match exactly continue to
work as expected. Add logic to only check multi-format events with
other multi-format events and single-format events to only check
single-format events during find.
Change system name of the multi-format event tracepoint to ensure that
multi-format events are isolated completely from single-format events.
This prevents single-format names from conflicting with multi-format
events if they end with the same suffix as the multi-format events.
Add a register_name (reg_name) to the user_event struct which allows for
split naming of events. We now have the name that was used to register
within user_events as well as the unique name for the tracepoint. Upon
registering events ensure matches based on first the reg_name, followed
by the fields and format of the event. This allows for multiple events
with the same registered name to have different formats. The underlying
tracepoint will have a unique name in the format of {reg_name}.{unique_id}.
For example, if both "test u32 value" and "test u64 value" are used with
the USER_EVENT_REG_MULTI_FORMAT the system would have 2 unique
tracepoints. The dynamic_events file would then show the following:
u:test u64 count
u:test u32 count
The actual tracepoint names look like this:
test.0
test.1
Both would be under the new user_events_multi system name to prevent the
older ABI from being used to squat on multi-formatted events and block
their use.
Deleting events via "!u:test u64 count" would only delete the first
tracepoint that matched that format. When the delete ABI is used all
events with the same name will be attempted to be deleted. If
per-version deletion is required, user programs should either not use
persistent events or delete them via dynamic_events.

S390:
* Changes to FPU handling came in via the main s390 pull request
* Only deliver to the guest the SCLP events that userspace has
requested.
* More virtual vs physical address fixes (only a cleanup since
virtual and physical address spaces are currently the same).
* Fix selftests undefined behavior.
x86:
* Fix a restriction that the guest can't program a PMU event whose
encoding matches an architectural event that isn't included in the
guest CPUID. The enumeration of an architectural event only says
that if a CPU supports an architectural event, then the event can be
programmed *using the architectural encoding*. The enumeration does
NOT say anything about the encoding when the CPU doesn't report support
the event *in general*. It might support it, and it might support it
using the same encoding that made it into the architectural PMU spec.
* Fix a variety of bugs in KVM's emulation of RDPMC (more details on
individual commits) and add a selftest to verify KVM correctly emulates
RDMPC, counter availability, and a variety of other PMC-related
behaviors that depend on guest CPUID and therefore are easier to
validate with selftests than with custom guests (aka kvm-unit-tests).
* Zero out PMU state on AMD if the virtual PMU is disabled, it does not
cause any bug but it wastes time in various cases where KVM would check
if a PMC event needs to be synthesized.
* Optimize triggering of emulated events, with a nice ~10% performance
improvement in VM-Exit microbenchmarks when a vPMU is exposed to the
guest.
* Tighten the check for "PMI in guest" to reduce false positives if an NMI
arrives in the host while KVM is handling an IRQ VM-Exit.
* Fix a bug where KVM would report stale/bogus exit qualification information
when exiting to userspace with an internal error exit code.
* Add a VMX flag in /proc/cpuinfo to report 5-level EPT support.
* Rework TDP MMU root unload, free, and alloc to run with mmu_lock held for
read, e.g. to avoid serializing vCPUs when userspace deletes a memslot.
* Tear down TDP MMU page tables at 4KiB granularity (used to be 1GiB). KVM
doesn't support yielding in the middle of processing a zap, and 1GiB
granularity resulted in multi-millisecond lags that are quite impolite
for CONFIG_PREEMPT kernels.
* Allocate write-tracking metadata on-demand to avoid the memory overhead when
a kernel is built with i915 virtualization support but the workloads use
neither shadow paging nor i915 virtualization.
* Explicitly initialize a variety of on-stack variables in the emulator that
triggered KMSAN false positives.
* Fix the debugregs ABI for 32-bit KVM.
* Rework the "force immediate exit" code so that vendor code ultimately decides
how and when to force the exit, which allowed some optimization for both
Intel and AMD.
* Fix a long-standing bug where kvm_has_noapic_vcpu could be left elevated if
vCPU creation ultimately failed, causing extra unnecessary work.
* Cleanup the logic for checking if the currently loaded vCPU is in-kernel.
* Harden against underflowing the active mmu_notifier invalidation
count, so that "bad" invalidations (usually due to bugs elsehwere in the
kernel) are detected earlier and are less likely to hang the kernel.
x86 Xen emulation:
* Overlay pages can now be cached based on host virtual address,
instead of guest physical addresses. This removes the need to
reconfigure and invalidate the cache if the guest changes the
gpa but the underlying host virtual address remains the same.
* When possible, use a single host TSC value when computing the deadline for
Xen timers in order to improve the accuracy of the timer emulation.
* Inject pending upcall events when the vCPU software-enables its APIC to fix
a bug where an upcall can be lost (and to follow Xen's behavior).
* Fall back to the slow path instead of warning if "fast" IRQ delivery of Xen
events fails, e.g. if the guest has aliased xAPIC IDs.
RISC-V:
* Support exception and interrupt handling in selftests
* New self test for RISC-V architectural timer (Sstc extension)
* New extension support (Ztso, Zacas)
* Support userspace emulation of random number seed CSRs.
ARM:
* Infrastructure for building KVM's trap configuration based on the
architectural features (or lack thereof) advertised in the VM's ID
registers
* Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to
x86's WC) at stage-2, improving the performance of interacting with
assigned devices that can tolerate it
* Conversion of KVM's representation of LPIs to an xarray, utilized to
address serialization some of the serialization on the LPI injection
path
* Support for _architectural_ VHE-only systems, advertised through the
absence of FEAT_E2H0 in the CPU's ID register
* Miscellaneous cleanups, fixes, and spelling corrections to KVM and
selftests
LoongArch:
* Set reserved bits as zero in CPUCFG.
* Start SW timer only when vcpu is blocking.
* Do not restart SW timer when it is expired.
* Remove unnecessary CSR register saving during enter guest.
* Misc cleanups and fixes as usual.
Generic:
* cleanup Kconfig by removing CONFIG_HAVE_KVM, which was basically always
true on all architectures except MIPS (where Kconfig determines the
available depending on CPU capabilities). It is replaced either by
an architecture-dependent symbol for MIPS, and IS_ENABLED(CONFIG_KVM)
everywhere else.
* Factor common "select" statements in common code instead of requiring
each architecture to specify it
* Remove thoroughly obsolete APIs from the uapi headers.
* Move architecture-dependent stuff to uapi/asm/kvm.h
* Always flush the async page fault workqueue when a work item is being
removed, especially during vCPU destruction, to ensure that there are no
workers running in KVM code when all references to KVM-the-module are gone,
i.e. to prevent a very unlikely use-after-free if kvm.ko is unloaded.
* Grab a reference to the VM's mm_struct in the async #PF worker itself instead
of gifting the worker a reference, so that there's no need to remember
to *conditionally* clean up after the worker.
Selftests:
* Reduce boilerplate especially when utilize selftest TAP infrastructure.
* Add basic smoke tests for SEV and SEV-ES, along with a pile of library
support for handling private/encrypted/protected memory.
* Fix benign bugs where tests neglect to close() guest_memfd files.

not cause any bug but it wastes time in various cases where KVM
would check if a PMC event needs to be synthesized
- Optimize triggering of emulated events, with a nice ~10%
performance improvement in VM-Exit microbenchmarks when a vPMU is
exposed to the guest
- Tighten the check for "PMI in guest" to reduce false positives if
an NMI arrives in the host while KVM is handling an IRQ VM-Exit
- Fix a bug where KVM would report stale/bogus exit qualification
information when exiting to userspace with an internal error exit
code
- Add a VMX flag in /proc/cpuinfo to report 5-level EPT support
- Rework TDP MMU root unload, free, and alloc to run with mmu_lock
held for read, e.g. to avoid serializing vCPUs when userspace
deletes a memslot
- Tear down TDP MMU page tables at 4KiB granularity (used to be
1GiB). KVM doesn't support yielding in the middle of processing a
zap, and 1GiB granularity resulted in multi-millisecond lags that
are quite impolite for CONFIG_PREEMPT kernels
- Allocate write-tracking metadata on-demand to avoid the memory
overhead when a kernel is built with i915 virtualization support
but the workloads use neither shadow paging nor i915 virtualization
- Explicitly initialize a variety of on-stack variables in the
emulator that triggered KMSAN false positives
- Fix the debugregs ABI for 32-bit KVM
- Rework the "force immediate exit" code so that vendor code
ultimately decides how and when to force the exit, which allowed
some optimization for both Intel and AMD
- Fix a long-standing bug where kvm_has_noapic_vcpu could be left
elevated if vCPU creation ultimately failed, causing extra
unnecessary work
- Cleanup the logic for checking if the currently loaded vCPU is
in-kernel
- Harden against underflowing the active mmu_notifier invalidation
count, so that "bad" invalidations (usually due to bugs elsehwere
in the kernel) are detected earlier and are less likely to hang the
kernel
x86 Xen emulation:
- Overlay pages can now be cached based on host virtual address,
instead of guest physical addresses. This removes the need to
reconfigure and invalidate the cache if the guest changes the gpa
but the underlying host virtual address remains the same
- When possible, use a single host TSC value when computing the
deadline for Xen timers in order to improve the accuracy of the
timer emulation
- Inject pending upcall events when the vCPU software-enables its
APIC to fix a bug where an upcall can be lost (and to follow Xen's
behavior)
- Fall back to the slow path instead of warning if "fast" IRQ
delivery of Xen events fails, e.g. if the guest has aliased xAPIC
IDs
RISC-V:
- Support exception and interrupt handling in selftests
- New self test for RISC-V architectural timer (Sstc extension)
- New extension support (Ztso, Zacas)
- Support userspace emulation of random number seed CSRs
ARM:
- Infrastructure for building KVM's trap configuration based on the
architectural features (or lack thereof) advertised in the VM's ID
registers
- Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to
x86's WC) at stage-2, improving the performance of interacting with
assigned devices that can tolerate it
- Conversion of KVM's representation of LPIs to an xarray, utilized
to address serialization some of the serialization on the LPI
injection path
- Support for _architectural_ VHE-only systems, advertised through
the absence of FEAT_E2H0 in the CPU's ID register
- Miscellaneous cleanups, fixes, and spelling corrections to KVM and
selftests
LoongArch:
- Set reserved bits as zero in CPUCFG
- Start SW timer only when vcpu is blocking
- Do not restart SW timer when it is expired
- Remove unnecessary CSR register saving during enter guest
- Misc cleanups and fixes as usual
Generic:
- Clean up Kconfig by removing CONFIG_HAVE_KVM, which was basically
always true on all architectures except MIPS (where Kconfig
determines the available depending on CPU capabilities). It is
replaced either by an architecture-dependent symbol for MIPS, and
IS_ENABLED(CONFIG_KVM) everywhere else
- Factor common "select" statements in common code instead of
requiring each architecture to specify it
- Remove thoroughly obsolete APIs from the uapi headers
- Move architecture-dependent stuff to uapi/asm/kvm.h
- Always flush the async page fault workqueue when a work item is
being removed, especially during vCPU destruction, to ensure that
there are no workers running in KVM code when all references to
KVM-the-module are gone, i.e. to prevent a very unlikely
use-after-free if kvm.ko is unloaded
- Grab a reference to the VM's mm_struct in the async #PF worker
itself instead of gifting the worker a reference, so that there's
no need to remember to *conditionally* clean up after the worker
Selftests:
- Reduce boilerplate especially when utilize selftest TAP
infrastructure
- Add basic smoke tests for SEV and SEV-ES, along with a pile of
library support for handling private/encrypted/protected memory
- Fix benign bugs where tests neglect to close() guest_memfd files"

- Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
from hotplugged memory rather than only from main memory. Series
"implement "memmap on memory" feature on s390".
- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"
"mm: convert mm counter to take a folio"
- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series "mm:
zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to
control the memmap_on_memory setting when the dax device is hotplugged
as system memory.
- Johannes Weiner has added the large series "mm: zswap: cleanups",
which does that.
- More DAMON work from SeongJae Park in the series
"mm/damon: make DAMON debugfs interface deprecation unignorable"
"selftests/damon: add more tests for core functionalities and corner cases"
"Docs/mm/damon: misc readability improvements"
"mm/damon: let DAMOS feeds and tame/auto-tune itself"
- In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension" Rakie Kim has developed a new mempolicy interleaving policy
wherein we allocate memory across nodes in a weighted fashion rather
than uniformly. This is beneficial in heterogeneous memory environments
appearing with CXL.
- Christophe Leroy has contributed some cleanup and consolidation work
against the ARM pagetable dumping code in the series "mm: ptdump:
Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute".
- Luis Chamberlain has added some additional xarray selftesting in the
series "test_xarray: advanced API multi-index tests".
- Muhammad Usama Anjum has reworked the selftest code to make its
human-readable output conform to the TAP ("Test Anything Protocol")
format. Amongst other things, this opens up the use of third-party
tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the process
has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown situations.
The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings" Ryan
Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's series
"Address some contpte nits" provides some followup work.
- In the series "mm/hugetlb: Restore the reservation" Breno Leitao has
fixed an obscure hugetlb race which was causing unnecessary page faults.
He has also added a reproducer under the selftest code.
- In the series "selftests/mm: Output cleanups for the compaction test",
Mark Brown did what the title claims.
- Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring".
- Even more zswap material from Nhat Pham. The series "fix and extend
zswap kselftests" does as claimed.
- In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in
our handling of DAX on archiecctures which have virtually aliasing data
caches. The arm architecture is the main beneficiary.
- Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic
improvements in worst-case mmap_lock hold times during certain
userfaultfd operations.
- Some page_owner enhancements and maintenance work from Oscar Salvador
in his series
"page_owner: print stacks and their outstanding allocations"
"page_owner: Fixup and cleanup"
- Uladzislau Rezki has contributed some vmalloc scalability improvements
in his series "Mitigate a vmap lock contention". It realizes a 12x
improvement for a certain microbenchmark.
- Some kexec/crash cleanup work from Baoquan He in the series "Split
crash out from kexec and clean up related config items".
- Some zsmalloc maintenance work from Chengming Zhou in the series
"mm/zsmalloc: fix and optimize objects/page migration"
"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"
- Zi Yan has taught the MM to perform compaction on folios larger than
order=0. This a step along the path to implementaton of the merging of
large anonymous folios. The series is named "Enable >0 order folio
memory compaction".
- Christoph Hellwig has done quite a lot of cleanup work in the
pagecache writeback code in his series "convert write_cache_pages() to
an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".
- Zi Yan has changed the page splitting code so we can split huge pages
into sizes other than order-0 to better utilize large folios. The
series is named "Split a folio to any lower order folios".
- David Hildenbrand has contributed the series "mm: remove
total_mapcount()", a cleanup.
- Matthew Wilcox has sought to improve the performance of bulk memory
freeing in his series "Rearrange batched folio freeing".
- Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
provides large improvements in bootup times on large machines which are
configured to use large numbers of hugetlb pages.
- Matthew Wilcox's series "PageFlags cleanups" does that.
- Qi Zheng's series "minor fixes and supplement for ptdesc" does that
also. S390 is affected.
- Cleanups to our pagemap utility functions from Peter Xu in his series
"mm/treewide: Replace pXd_large() with pXd_leaf()".
- Nico Pache has fixed a few things with our hugepage selftests in his
series "selftests/mm: Improve Hugepage Test Handling in MM Selftests".
- Also, of course, many singleton patches to many things. Please see
the individual changelogs for details.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
"The major features are support for LPA2 (52-bit VA/PA with 4K and 16K
pages), the dpISA extension and Rust enabled on arm64. The changes are
mostly contained within the usual arch/arm64/, drivers/perf, the arm64
Documentation and kselftests. The exception is the Rust support which
touches some generic build files.
Summary:
- Reorganise the arm64 kernel VA space and add support for LPA2 (at
stage 1, KVM stage 2 was merged earlier) - 52-bit VA/PA address
range with 4KB and 16KB pages
- Enable Rust on arm64
- Support for the 2023 dpISA extensions (data processing ISA), host
only
- arm64 perf updates:
- StarFive's StarLink (integrates one or more CPU cores with a
shared L3 memory system) PMU support
- Enable HiSilicon Erratum 162700402 quirk for HIP09
- Several updates for the HiSilicon PCIe PMU driver
- Arm CoreSight PMU support
- Convert all drivers under drivers/perf/ to use .remove_new()
- Miscellaneous:
- Don't enable workarounds for "rare" errata by default
- Clean up the DAIF flags handling for EL0 returns (in preparation
for NMI support)
- Kselftest update for ptrace()
- Update some of the sysreg field definitions
- Slight improvement in the code generation for inline asm I/O
accessors to permit offset addressing
- kretprobes: acquire regs via a BRK exception (previously done
via a trampoline handler)
- SVE/SME cleanups, comment updates
- Allow CALL_OPS+CC_OPTIMIZE_FOR_SIZE with clang (previously
disabled due to gcc silently ignoring -falign-functions=N)"

sound updates for 6.9-rc1
This was a relatively calm development cycle. Most of changes are
rather small device-specific fixes and enhancements. The only
significant changes in ALSA core are code refactoring with the recent
cleanup infrastructure, which should bring no functionality changes.
Some highlights below:
Core:
- Lots of cleanups in ALSA core code with automatic kfree cleanup
and locking guard macros
- New ALSA core kunit test
ASoC:
- SoundWire support for AMD ACP 6.3 systems
- Support for reporting version information for AVS firmware
- Support DSPless mode for Intel Soundwire systems
- Support for configuring CS35L56 amplifiers using EFI calibration
data
- Log which component is being operated on as part of power management
trace events.
- Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x
HD- and USB-audio:
- More Cirrus HD-audio codec support
- TAS2781 HD-audio codec fixes
- Scarlett2 mixer fixes
Others:
- Enhancement of virtio driver for audio control supports
- Cleanups of legacy PM code with new macros
- Firewire sound updates

gpio updates for v6.9
Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to GPIO device
structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being unbound while
the API calls are in progress
- don't dereference the SRCU-protected chip pointer if the information we need
can be obtained from the GPIO device structure
- move some of the information contained in struct gpio_chip to struct
gpio_device to further reduce the need to dereference the former
- pass the GPIO device struct instead of the GPIO chip to sysfs callback to,
again, reduce the need for accessing the latter
- get GPIO descriptors from the GPIO device, not from the chip for the same
reason
- allow for mostly lockless operation of the GPIO driver API: assure
consistency with SRCU and atomic operations
- remove the global GPIO spinlock
- remove the character device RW semaphore
Core GPIOLIB:
- constify pointers in GPIO API where applicable
- unify the GPIO counting APIs for ACPI and OF
- provide a macro for iterating over all GPIOs, not only the ones that are
requested
- remove leftover typedefs
- pass the consumer device to GPIO core in devm_fwnode_gpiod_get_index() for
improved logging
- constify the GPIO bus type
- don't warn about removing GPIO chips with descriptors still held by users as
we can now handle this situation gracefully
- remove unused logging helpers
- unexport functions that are only used internally in the GPIO subsystem
- set the device type (assign the relevant struct device_type) for GPIO devices
New drivers:
- add the ChromeOS EC GPIO driver
Driver improvements:
- allow building gpio-vf610 with COMPILE_TEST as well as disabling it in
menuconfig (before it was always built for i.MX cofigs)
- count the number of EICs using the device properties instead of hard-coding
it in gpio-eic-sprd
- improve the device naming, extend the debugfs output and add lockdep asserts
to gpio-sim
DT bindings:
- document the 'label' property for gpio-pca9570
- convert aspeed,ast2400-gpio bindings to DT schema
- disallow unevaluated properties for gpio-mvebu
- document a new model in renesas,rcar-gpio
Documentation:
- improve the character device kerneldocs in user-space headers
- add proper documentation for the character device uAPI (both v1 and v2)
- move the sysfs and gpio-mockup docs into the "obsolete" section
- improve naming consistency for GPIO terms
- clarify the line values description for sysfs
- minor docs improvements
- improve the driver API contract for setting GPIO direction
- mark unsafe APIs as deprecated in kerneldocs and suggest replacements
Other:
- remove an obsolete test from selftests

Pull gpio updates from Bartosz Golaszewski:
"The biggest feature is the locking overhaul. Up until now the
synchronization in the GPIO subsystem was broken. There was a single
spinlock "protecting" multiple data structures but doing it wrong (as
evidenced by several places where it would be released when a sleeping
function was called and then reacquired without checking the protected
state).
We tried to use an RW semaphore before but the main issue with GPIO is
that we have drivers implementing the interfaces in both sleeping and
non-sleeping ways as well as user-facing interfaces that can be called
both from process as well as atomic contexts. Both ends converge in
the same code paths that can use neither spinlocks nor mutexes. The
only reasonable way out is to use SRCU and go mostly lockless. To that
end: we add several SRCU structs in relevant places and use them to
assure consistency between API calls together with atomic reads and
writes of GPIO descriptor flags where it makes sense.
This code has spent several weeks in next and has received several
fixes in the first week or two after which it stabilized nicely. The
GPIO subsystem is now resilient to providers being suddenly unbound.
We managed to also remove the existing character device RW semaphore
and the obsolete global spinlock.
Other than the locking rework we have one new driver (for Chromebook
EC), much appreciated documentation improvements from Kent and the
regular driver improvements, DT-bindings updates and GPIOLIB core
tweaks.
Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to
GPIO device structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being

Prior to the start of the LSM stacking work it was important that IMA/EVM were separate from the rest of the LSMs, complete with their own hooks, infrastructure, etc. as it was the only way to enable IMA/EVM at the same time as a LSM. However, now that the bulk of the LSM infrastructure supports multiple simultaneous LSMs, we can simplify things greatly by bringing IMA/EVM into the LSM infrastructure as proper LSMs. This is something I've wanted to see happen for quite some time and Roberto was kind enough to put in the work to make it happen. - Use the LSM hook default values to simplify the call_int_hook() macro Previously the call_int_hook() macro required callers to supply a default return value, despite a default value being specified when the LSM hook was defined. This simplifies the macro by using the defined default return value which makes life easier for callers and should also reduce the number of return value bugs in the future (we've had a few pop up recently, hence this work). - Use the KMEM_CACHE() macro instead of kmem_cache_create() The guidance appears to be to use the KMEM_CACHE() macro when possible and there is no reason why we can't use the macro, so let's use it. - Fix a number of comment typos in the LSM hook comment blocks Not much to say here, we fixed some questionable grammar decisions in the LSM hook comment blocks. * tag 'lsm-pr-20240312' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (28 commits) cred: Use KMEM_CACHE() instead of kmem_cache_create() lsm: use default hook return value in call_int_hook() lsm: fix typos in security/security.c comment headers integrity: Remove LSM ima: Make it independent from 'integrity' LSM evm: Make it independent from 'integrity' LSM evm: Move to LSM infrastructure ima: Move IMA-Appraisal to LSM infrastructure ima: Move to LSM infrastructure integrity: Move integrity_kernel_module_request() to IMA security: Introduce key_post_create_or_update hook security: Introduce inode_post_remove_acl hook security: Introduce inode_post_set_acl hook security: Introduce inode_post_create_tmpfile hook security: Introduce path_post_mknod hook security: Introduce file_release hook security: Introduce file_post_open hook security: Introduce inode_post_removexattr hook security: Introduce inode_post_setattr hook security: Align inode_setattr hook definition with EVM ... |

Networking changes for 6.9.
Core & protocols
----------------
- Large effort by Eric to lower rtnl_lock pressure and remove locks:
- Make commonly used parts of rtnetlink (address, route dumps etc.)
lockless, protected by RCU instead of rtnl_lock.
- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core
instead of once for each driver / callback.
- Remove locks / serialization in the socket diag interface.
- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
- Remove the dev_base_lock, depend on RCU where necessary.
- Support busy polling on a per-epoll context basis. Poll length
and budget parameters can be set independently of system defaults.
- Introduce struct net_hotdata, to make sure read-mostly global config
variables fit in as few cache lines as possible.
- Add optional per-nexthop statistics to ease monitoring / debug
of ECMP imbalance problems.
- Support TCP_NOTSENT_LOWAT in MPTCP.
- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.
- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.
- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.
- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.
- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for
use on fastpaths).
- Speed up scanning for expired routes by keeping a dedicated list.
- Speed up "generic" XDP by trying harder to avoid large allocations.
- Support attaching arbitrary metadata to netconsole messages.
Things we sprinkled into general kernel code
--------------------------------------------
- Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce
VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena).
- Rework selftest harness to enable the use of the full range of
ksft exit code (pass, fail, skip, xfail, xpass).
Netfilter
---------
- Allow userspace to define a table that is exclusively owned by a daemon
(via netlink socket aliveness) without auto-removing this table when
the userspace program exits. Such table gets marked as orphaned and
a restarting management daemon can re-attach/regain ownership.
- Speed up element insertions to nftables' concatenated-ranges set type.
Compact a few related data structures.
BPF
---
- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.
- Introduce bpf_arena which is sparse shared memory region between BPF
program and user space where structures inside the arena can have
pointers to other areas of the arena, and pointers work seamlessly
for both user-space programs and BPF programs.
- Introduce may_goto instruction that is a contract between the verifier
and the program. The verifier allows the program to loop assuming it's
behaving well, but reserves the right to terminate it.
- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.
- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops type.
- Add support for retrieval of cookies for perf/kprobe multi links.
- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF firewalls.
- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF objects.
Wireless
--------
- Add SPP (signaling and payload protected) AMSDU support.
- Support wider bandwidth OFDMA, as required for EHT operation.
Driver API
----------
- Major overhaul of the Energy Efficient Ethernet internals to support
new link modes (2.5GE, 5GE), share more code between drivers
(especially those using phylib), and encourage more uniform behavior.
Convert and clean up drivers.
- Define an API for querying per netdev queue statistics from drivers.
- IPSec: account in global stats for fully offloaded sessions.
- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.
- Enable Rx hashing (RSS) on GTP protocol fields.
Misc
----
- Improvements and refactoring all over networking selftests.
- Create uniform module aliases for TC classifiers, actions,
and packet schedulers to simplify creating modprobe policies.
- Address all missing MODULE_DESCRIPTION() warnings in networking.
- Extend the Netlink descriptions in YAML to cover message encapsulation
or "Netlink polymorphism", where interpretation of nested attributes
depends on link type, classifier type or some other "class type".

drm/xe/uapi: Add IP version and stepping to GT list query
For modern platforms (MTL and later), both kernel and userspace drivers are expected to apply GT programming and workarounds based on the IP version and stepping self-reported by the GT hardware via the GMD_ID registers. Since userspace drivers can't access these registers directly, pass along the version and stepping information via the GT list query. Note that the new query fields will remain 0's when running on pre-GMD_ID platforms. Userspace is expected to continue using PCI devid / revid on those older platforms. Although the hardware also has a GMD_ID register for display version/stepping, that value is intentionally *not* included anywhere in the Xe uapi. Display userspace should be using platform-agnostic APIs and auto-detecting platform capabilities rather than matching specific IP versions. v2: - s/revid/rev/ (Lucas) - Fix kerneldoc copy/paste mistakes Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240312211229.2871288-4-matthew.d.roper@intel.com |

Merge tag 'for-6.9-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"Mostly stabilization, refactoring and cleanup changes. There rest are
minor performance optimizations due to caching or lock contention
reduction and a few notable fixes.
Performance improvements:
- minor speedup in logging when repeatedly allocated structure is
preallocated only once, improves latency and decreases lock
contention
- minor throughput increase (+6%), reduced lock contention after
clearing delayed allocation bits, applies to several common
workload types
- skip full quota rescan if a new relation is added in the same
transaction
Fixes:
- zstd fix for inline compressed file in subpage mode, updated
version from the 6.8 time
- proper qgroup inheritance ioctl parameter validation
- more fiemap followup fixes after reduced locking done in 6.8:
- fix race when detecting delalloc ranges
Core changes:
- more debugging code:
- added assertions for a very rare crash in raid56 calculation
- tree-checker dumps page state to give more insights into
possible reference counting issues
- add checksum calculation offloading sysfs knob, for now enabled
under DEBUG only to determine a good heuristic for deciding the
offload or synchronous, depends on various factors (block group
profile, device speed) and is not as clear as initially thought
(checksum type)
- error handling improvements, added assertions
- more page to folio conversion (defrag, truncate), cached size and
shift

Input: allocate keycode for Display refresh rate toggle
Newer Lenovo Yogas and Legions with 60Hz/90Hz displays send a wmi event when Fn + R is pressed. This is intended for use to switch between the two refresh rates. Allocate a new KEY_REFRESH_RATE_TOGGLE keycode for it.

The main changes are: 1) Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce VM_SPARSE kind and vm_area_[un]map_pages to be used in bpf_arena, from Alexei. 2) Introduce bpf_arena which is sparse shared memory region between bpf program and user space where structures inside the arena can have pointers to other areas of the arena, and pointers work seamlessly for both user-space programs and bpf programs, from Alexei and Andrii. 3) Introduce may_goto instruction that is a contract between the verifier and the program. The verifier allows the program to loop assuming it's behaving well, but reserves the right to terminate it, from Alexei. 4) Use IETF format for field definitions in the BPF standard document, from Dave. 5) Extend struct_ops libbpf APIs to allow specify version suffixes for stuct_ops map types, share the same BPF program between several map definitions, and other improvements, from Eduard. 6) Enable struct_ops support for more than one page in trampolines, from Kui-Feng. 7) Support kCFI + BPF on riscv64, from Puranjay. 8) Use bpf_prog_pack for arm64 bpf trampoline, from Puranjay. 9) Fix roundup_pow_of_two undefined behavior on 32-bit archs, from Toke. ==================== Link: https://lore.kernel.org/r/20240312003646.8692-1-alexei.starovoitov@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
