Pull CRC updates from Eric Biggers:
"Accelerate CRC64-NVME for 32-bit ARM by refactoring the arm64 NEON
intrinsics implementation to be shared by 32-bit and 64-bit.
Also apply a similar cleanup to the 32-bit ARM NEON implementation of
xor_gen(), where it now reuses code from the 64-bit implementation"

Pull slab updates from Vlastimil Babka:
- Support for "allocation tokens" (currently available in Clang 22+)
for smarter partitioning of kmalloc caches based on the allocated
object type, which can be enabled instead of the "random"
per-caller-address-hash partitioning.
It should be able to deterministically separate types containing a
pointer from those that do not (Marco Elver)
- Improvements and simplification of the kmem_cache_alloc_bulk() and
mempool_alloc_bulk() API. This includes adaptation of callers
(Christoph Hellwig)
- Performance improvements and cleanups related mostly to sheaves
refill (Hao Li, Shengming Hu, Vlastimil Babka)

Pull spi updates from Mark Brown:
"This has been quite a busy release, mainly due to the subsystem wide
work Johan Hovold has done to modernise resource allocation for the
subsystem on probe, the subsystem did some very clever allocation
management pre devm which didn't quite mesh comfortably with managed

removal bugs.
- Cleanup and simplification of controller struct allocation, moving
everything over to devm and making the devm APIs more robust, from

Add test_iou_zcrx_large_buf, which runs iou-zcrx with rx_buf_len >
page size (-x 2) through a netkit-leased RX queue. The netkit ifindex
is opaque to io_uring, but rx_page_size is honoured by the leased
physical qops via netif_mp_open_rxq()'s lease redirect.
Originally, I also added a BIG TCP variant on top, but dropped it
here as fbnic (and the QEMU fbnic model) has no BIG TCP support
to exercise it as this point.
Tested against the QEMU fbnic emulation. The new test exercises
the > page rx_buf_len path only when the leased NIC advertises
QCFG_RX_PAGE_SIZE; otherwise it skips.
For fbnic, I used Bjorn's patches locally [0]:

The HW counterpart of nk_qlease.py was carrying its lease setup in main()
and stashing src_queue / nk_queue / nk_*_ifname on cfg, which had drawbacks
called out during the review at [0].
This is the deferred half of the cleanup that landed in commit e254ffb9502c
("selftests/net: Split netdevsim tests from HW tests in nk_qlease") which
was the SW counterpart of nk_qlease.py.
While at it, convert the open-coded "ip netns exec" prefixes in the test

Several places in perf need to check whether an evsel is a kprobe or
uprobe, which requires looking up the PMU by name via evsel__find_pmu().
This lookup walks the PMU list each time, which is wasteful when the
same evsel is checked repeatedly.
Add evsel__is_kprobe(), evsel__is_uprobe(), and evsel__is_probe() that
resolve the probe type on first call via evsel__pmu_name() and cache
the result in a 3-bit field (probe_type) in struct evsel. The field
fits in existing padding after the bool fields, so struct size does not
grow.
The enum uses PROBE__UNKNOWN (0) as the uninitialized sentinel —
explicitly set in evsel__init() — so the lookup happens on first use.
PROBE__NOPE (1) caches "not a probe" to avoid repeated negative lookups.
PMU-based probes (kprobe/uprobe PMU) are detected by PMU name.
Ftrace-based dynamic probes (created via tracefs, reported as PMU
"tracepoint") are detected by the __probe_ip field that the kernel
adds to all dynamic probe formats. This covers kprobes, uprobes, and
fprobes regardless of their group/system name.

metadata[j][CS_ETM_CPU] is a u64 from perf.data, but the comparison
with max_cpu casts it to (int). A crafted value like 0xFFFFFFFF becomes
-1 after the cast, which compares less than max_cpu (0), so the queue
array is never sized to accommodate it. When the value is later passed
to cs_etm__get_queue(), it indexes queue_array with the original large
value, causing an out-of-bounds access.
Validate that CS_ETM_CPU fits in an int before using it in the signed
comparison.

bpil_offs_to_addr() converts offsets stored in perf.data's
bpf_prog_info_linear structure into heap pointers by adding the offset
to the data allocation base. The offsets come from untrusted file input
and are not validated against data_len.
If an offset exceeds data_len, the computed address points outside the
allocated data buffer. Callers like synthesize_bpf_prog_name() then
dereference prog_tags[sub_id] or func_info pointers, reading arbitrary
heap memory.
Add a bounds check: when an offset exceeds data_len, zero the field
and skip the conversion. This prevents out-of-bounds pointer
construction from crafted perf.data files.

bpf_metadata_alloc() computes event_size from the number of BPF metadata
variables and stores it in header.size, which is __u16. With 204 or
more .rodata variables prefixed "bpf_metadata_", event_size exceeds
65535 and silently truncates.
The truncated header.size causes synthesize_perf_record_bpf_metadata()
to allocate a buffer sized by the truncated value, then memcpy the full
event data into it — a heap buffer overflow.
Add a check that event_size fits in __u16 before proceeding. BPF
programs with that many metadata variables are exotic enough that
silently dropping the metadata is acceptable.

synthesize_bpf_prog_name() computes a pointer into the func_info array
using sub_id * info->func_info_rec_size without validating either value.
Both come from perf.data and are untrusted:
- A func_info_rec_size smaller than sizeof(struct bpf_func_info) means
the finfo pointer would reference a truncated entry, reading past it
into adjacent data.
- A sub_id >= nr_func_info computes an offset past the func_info buffer,
causing an out-of-bounds read.
Add bounds checks for both values before computing the pointer offset.
When validation fails, fall through to the non-BTF name path instead
of reading garbage.

map__findnew_thread() marks color-pid threads by storing (void*)1 as
the thread private data via thread__set_priv(). This sentinel value
causes two problems:
1. thread__get_runtime() returns (void*)1 as a struct thread_runtime
pointer. Any field access (e.g. tr->shortname) dereferences address
1, which is an unmapped page — immediate segfault.
2. cmd_sched() registers free() as the thread priv destructor, so thread
cleanup calls free((void*)1) — undefined behavior that corrupts the
heap on many allocators.
Fix by adding a 'color' flag to struct thread_runtime and allocating a
real runtime struct for color-pid threads. thread__has_color() now
checks the flag instead of relying on priv being non-NULL.

hwmon_pmu__describe_items() checks 'if (fd > 0)' after openat(), which
incorrectly rejects fd 0. While fd 0 is normally stdin, if stdin has
been closed (common in daemon/service contexts), the kernel reuses fd 0
for the next open. With fd > 0, the sysfs file is not read and the fd
is leaked.
Change to 'if (fd >= 0)' to match the standard openat() error check.

filename__decompress() has an early return for files that are not
actually compressed, where it calls open() directly. When open()
fails, the function returns -1 but never sets *err. The caller chain
(decompress_kmodule → dso__decompress_kmodule_path → dso__get_filename)
then reads *dso__load_errno(dso) to set errno, but that field was never
populated, so errno gets a stale or zero value.
With errno=0, __open_dso() computes fd = -errno = 0, which is non-
negative, so callers treat fd 0 (stdin) as a valid DSO file descriptor.
Set *err = errno when open() fails on the uncompressed path, matching
the error handling on the compressed path at line 354.

n_namesz and n_descsz are 0), the code computes n = namesz + descsz = 0
and calls read(fd, bf, 0). read() with count 0 returns 0, which
matches the expected (ssize_t)n value, so the error check passes and
the loop repeats — reading the same zero bytes and spinning forever.
This can happen with corrupted or zero-padded sysfs pseudo-files.
Add a check for n == 0 before the read, since no valid ELF note has
both name and description of zero length.

filename__read_build_id() stores ELF p_filesz in a ssize_t variable.
A crafted 32-bit ELF with p_filesz = 0xFFFFFFFF produces ssize_t value
-1. The comparison `p_filesz > buf_size` evaluates false because signed
-1 is less than any non-negative buf_size, so the realloc is skipped and
buf remains NULL.
The subsequent read(fd, NULL, -1) returns -1, which equals p_filesz,
passing the error check. read_build_id() then dereferences the NULL
buffer.
Add an explicit check for p_filesz <= 0 before using the value,
catching both zero-length and sign-wrapped negative sizes from crafted
ELF files.

filename__read_build_id() byte-swaps 32-bit ELF program headers on
cross-endian files, but line 178 passes p_offset to bswap_32() instead
of p_filesz:
hdrs.phdr32[i].p_filesz = bswap_32(hdrs.phdr32[i].p_offset);
This clobbers p_filesz with the already-swapped p_offset value. The
64-bit path on line 182 is correct and swaps p_filesz from p_filesz.
The consequence is that the PT_NOTE segment read uses the wrong size,
which can cause either a short read (missing the build-id) or an
oversized read (reading past the segment into adjacent data).
Fix by swapping the correct field.

====================
ionic: Expose more port stats to ethtool [part]
The primary aim of this patchset is to support the reporting of new port
statistics (and one old one) that firmware sends to the driver. A scheme
for these extra stats is introduced in order to prevent devices that
don't support these new statistics from unconditionally setting them or
reporting them in ethtool.

The number of times that link has gone down at the port level is tracked
by the firmware and sent to the driver via regular DMA writes to an
instance of struct ionic_port_status in the driver's memory.
This statistic was never reported in favor of a driver-derived stat, but
doing it in the driver was never necessary since firmware had been
reporting it the whole time. Since it would be more accurate and true to
the description of the statistic to get this count at the PHY level,
replace the driver-calculated statistic with one derived from the
firmware one and remove the driver-calculated one entirely.
The stat reported by the ethtool .get_link_ext_stats() handler is
normalized to 0 on driver load and any device resets that require the
driver to rebuild state while also handling overflows.

This stat contains the number of total bits that the PHY has received;
it's useful for BER calculations. Add it to the ethtool stats output.
However, since this is one of the new "extra port stats", it's reported
in a different manner than the existing port stats and only
conditionally added to the ethtool stats output list: both the
DEV_CAP_EXTRA_STATS capability must be supported by the firmware, and
the firmware must set the value of the statistic to something other than
IONIC_STAT_INVALID.
To help support this scheme, the extra port stats region is initialized to
0xff's/IONIC_STAT_INVALID by the driver, to ensure the statistics that
the driver knows about but the firmware does not are still invalid
to the driver.

Add a new structure to report additional statistics from the firmware to
struct ionic_port_info. This new struct currently only contains FEC
related statistics, but any new port-level statistics collected by the
firmware would go into it.
The new structure is located in the same area as the unused
ionic_port_pb_stats structure, so this patch also removes that and its
supporting enumerations since they was never used in this driver.
Finally, to indicate firmware support for the new structure, introduce a
new device capability that the driver can use to see if the attached
device supports reporting these extra stats.

The current check will fail if SR-IOV is not initialized for the
physical function; this is because is_physfn is 0 if sriov_init() isn't
run or fails. Change the check that prevents getting the link down count
to use is_virtfn instead so that VFs don't get this functionality, which
was the original intent.

====================
net: dsa: mxl862xx: SerDes ports
Add support for the two SerDes PCS interfaces of the MxL862xx switch
ICs, which can both either be used to connect PHYs or SFP cages, or as
CPU port(s). 1000Base-X, 2500Base-X, 10GBase-R, 10GBase-KR, SGMII,
QSGMII and USXGMII (single 10G or quad 2.5G) are supported.
The firmware only added the API to directly control the PCS as of
version 1.0.84, so the PCS features are gated behind a version check.
As the driver is growing do some refactoring to break out the phylink
parts into mxl862xx-phylink.h.
