c41cfae42c spi: Updates for v7.2 
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
 allocations and made it far too easy to introduce error handling and
 removal bugs.
 
  - Cleanup and simplification of controller struct allocation, moving
    everything over to devm and making the devm APIs more robust, from
    Johan Hovold
  - Support for spi-mem devices that don't assert chip select and support
    for a secondary read command for memory mapped flashes, some commits
    for this are shared with mtd.
  - Support for SpacemiT K1.
 
 There will be a simple add/add conflict with the i2c-host tree in the
 x86 quirk data in drivers/acpi/acpi_apd.c.

Merge tag 'gpio-updates-for-v7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "There's one new driver, one legacy driver removed, a kunit test-suite
  for the GPIO core, support for new models in existing drivers and a
  slew of various changes in many places though I can't think of
  anything controversial that would stand out - it's been a relatively
  calm cycle.

  GPIO core:
   - Add an initial set of kunit test cases for the GPIO subsystem
   - Use the devres owner as the GPIO chip's parent in absence of any
     other parent
   - Fix const-correctness of GPIO chip SRCU guards
   - Provide new GPIO consumer interfaces: gpiod_is_single_ended() and
     fwnode_gpiod_get()
   - Quarantine all legacy GPIO APIs in linux/gpio/legacy.h
   - Use __ro_after_init where applicable

  New drivers:
   - Add driver for the GPIO controller on Waveshare DSI TOUCH panels

  Removed drivers:
   - Remove the obsolete ts5500 GPIO driver

  Driver updates:
   - Modernize gpio-timberdale: remove platform data support and use
     generic device property accessors
   - Extend test build coverage by enabling COMPILE_TEST for more GPIO
     drivers
   - Add some missing dependencies in Kconfig
   - Add support for sparse fixed direction to gpio-regmap
   - Remove dead code from gpio-nomadik
   - use BIT() in gpio-mxc
   - use bitmap_complement() in gpio-xilinx and gpio-pca953x
   - Use more appropriate printing functions where applicable
   - Use named initializers for platform_device_id and i2c_device_id
     arrays
   - Convert gpio-altera to using the generic GPIO chip helper library
   - Add support for new models to gpio-dwapb, gpio-zynq, gpio-usbio and
     gpio-tegra186
   - Unify the naming convention for Qualcomm in GPIO drivers
   - Fix interrupt bank mapping to GPIO chips in gpio-mt7621
   - Add support for the lines-initial-states property to gpio-74x164
   - Switch to using dynamic GPIO base in gpio-ixp4xx
   - Move the handling of an OF quirk from ASoC to gpiolib-of.c where
     other such quirks live
   - Use handle_bad_irq() in gpio-ep93xx
   - Some other minor tweaks and refactorings

  Devicetree bindings:
   - Document the Waveshare GPIO controller for DSI TOUCH panels
   - Document new models: Tegra238 in gpio-tegra186 and EIO GPIO in
     gpio-zynq
   - Add new properties for gpio-dwapb and fairchild,74hc595
   - Fix whitespace issues
   - Sort compatibles alphabetically in gpio-zynq

  Documentation:
   - Fix kerneldoc warnings in gpio-realtek-otto

  Misc:
   - Attach software nodes representing GPIO chips to the actual struct
     device objects associated with them in some legacy platforms
     enabling real firmware node lookup instead of string matching
   - Drop unneeded dependencies on OF_GPIO from bus and staging drivers"

5024cfc8a3 selftests/net: Add netkit io_uring ZC test for large rx_buf_len 
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]:

  # ./nk_qlease.py

9212e395c6 perf evsel: Add lazy-initialized probe type detection helpers 
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.

033e85edfb perf bpf: Bounds-check array offsets in bpil_offs_to_addr() 
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.

2d6ea08750 perf bpf: Reject oversized BPF metadata events that truncate header.size 
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.

   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.

cfafef390c perf hwmon: Fix fd check to accept fd 0 in hwmon_pmu__describe_items() 
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.

7b0df6f4d4 perf tools: Use snprintf() for root_dir path construction 
get_kernel_version() in machine.c and dso__load_guest_kernel_sym() in
symbol.c use sprintf() to construct paths by prepending root_dir to
"/proc/version" and "/proc/kallsyms" respectively.  Both write into
PATH_MAX stack buffers, but root_dir comes from --guestmount or KVM
configuration and is not length-checked.  A root_dir at or near
PATH_MAX causes a stack buffer overflow.

Switch to snprintf() with sizeof(path) to prevent overflow.

d2c6069d68 perf dso: Set error code when open() fails on uncompressed fallback path 
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.

dso__get_filename() allocates name with malloc(PATH_MAX), but the
dso__filename_with_chroot() path replaces name with an asprintf'd
exact-size string (e.g. 8 bytes for "/a/b.ko").  When the DSO needs
decompression, dso__decompress_kmodule_path() writes the temp path
("/tmp/perf-kmod-XXXXXX", 22 bytes) into newpath, and strcpy(name,
newpath) overflows the smaller allocation.

Replace the strcpy with strdup(newpath) + free(name) so the buffer
is always correctly sized for its content.

063c647b24 perf symbols: Break infinite loop on zero-filled notes in sysfs__read_build_id() 
sysfs__read_build_id() iterates ELF note headers from sysfs files in a
while(1) loop.  If the file contains a zero-filled note header (both
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.

2a37165443 perf symbols: Validate p_filesz before use in filename__read_build_id() 
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.

081b387c73 perf symbols: Fix bswap copy-paste error for 32-bit ELF p_filesz 
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.

3277e605ac ionic: Get "link_down_count" ext link stat from firmware 
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.

cb683ff6ee ionic: Report "rx_bits_phy" stat to ethtool 
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.

433bc50081 ionic: Update ionic_if.h with new extra port stats 
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.

 - Skip SNP initialization in the CCP driver immediately when the
   preparation step fails rather than proceeding to an operation that
   will certainly fail

 - Abort SNP preparation and return an error when not all CPUs are
   online, since the firmware enforces that every CPU enables SNP and
   will fail init if not

 - Simplify the VMM communication exception entry path by replacing
   separate kernel and user mode macros with a single handler that
   dispatches based on the current privilege level

1959005463 Merge branch 'net-dsa-mxl862xx-serdes-ports' 
Daniel Golle says:

====================
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.

13ea4d4888 net: dsa: mxl862xx: add support for SerDes ports 
The MxL862xx has two XPCS/SerDes interfaces (XPCS0 for ports 9-12,
XPCS1 for ports 13-16). Each can operate in various single-lane modes
(SGMII, 1000Base-X, 2500Base-X, 10GBase-R, 10GBase-KR, USXGMII) or as
QSGMII or 10G_QXGMII providing four sub-ports per interface.

Implement phylink PCS operations using the firmware's XPCS API:

  - pcs_enable/pcs_disable: refcount the sub-ports sharing an XPCS
    and power it down once the last sub-port is released.
  - pcs_config: configure negotiation mode and CL37/SGMII advertising.
  - pcs_get_state: read link state and the link-partner ability word
    from firmware and decode using phylink's standard CL37, SGMII, and
    USXGMII decoders.
  - pcs_an_restart: restart CL37 or CL73 auto-negotiation.
  - pcs_link_up: force speed/duplex for SGMII.
  - pcs_inband_caps: report per-mode in-band status capabilities.

Register a PCS instance for each SerDes interface and
QSGMII/10G_QXGMII sub-ports during setup. Advertise the supported
interface modes in phylink_get_caps based on port number.

Firmware older than 1.0.84 lacks the XPCS API and instead configures
the SerDes itself, using defaults stored in flash. mac_select_pcs()
returns NULL in that case while the single-lane interface modes stay
advertised, so a CPU port keeps working in the firmware-configured
mode.

Lacking support for expressing PHY-side role modes in Linux only the
MAC-side of SGMII, QSGMII, USXGMII and 10G_QXGMII are implemented for
now.

7dab839724 net: dsa: mxl862xx: move API macros to mxl862xx-host.h 
Move the MXL862XX_API_WRITE, MXL862XX_API_READ and
MXL862XX_API_READ_QUIET convenience macros from mxl862xx.c to
mxl862xx-host.h next to the mxl862xx_api_wrap() prototype they wrap.
This makes them available to other compilation units that include
mxl862xx-host.h, which is needed once the SerDes PCS code in
mxl862xx-phylink.c also calls firmware commands.

No functional change.

c103433200 net: dsa: mxl862xx: move phylink stubs to mxl862xx-phylink.c 
Move the phylink MAC operations and get_caps callback from mxl862xx.c
into a dedicated mxl862xx-phylink.c file. This prepares for the SerDes
PCS implementation which adds substantial phylink/PCS code -- keeping
it in a separate file avoids function-position churn in the main
driver file.

No functional change.

937137db79 net: dsa: mxl862xx: store firmware version for feature gating 
Query the firmware version at init (already done in wait_ready),
cache it in priv->fw_version, and provide MXL862XX_FW_VER_MIN()
for version-gated code paths throughout the driver.

MXL862XX_FW_VER() packs major/minor/revision into a u32 with
bitwise shifts so that versions compare with natural ordering,
independent of host endianness.
