Pull arm64 updates from Will Deacon:
"There's good stuff across the board, including some nice mm
improvements for CPUs with the 'noabort' BBML2 feature and a clever
patch to allow ptdump to play nicely with block mappings in the
vmalloc area.
Confidential computing:
- Add support for accepting secrets from firmware (e.g. ACPI CCEL)
and mapping them with appropriate attributes.
CPU features:
- Advertise atomic floating-point instructions to userspace
- Extend Spectre workarounds to cover additional Arm CPU variants
- Extend list of CPUs that support break-before-make level 2 and
guarantee not to generate TLB conflict aborts for changes of
mapping granularity (BBML2_NOABORT)
- Add GCS support to our uprobes implementation.
Documentation:
- Remove bogus SME documentation concerning register state when
entering/exiting streaming mode.
Entry code:
- Switch over to the generic IRQ entry code (GENERIC_IRQ_ENTRY)
- Micro-optimise syscall entry path with a compiler branch hint.
Memory management:
- Enable huge mappings in vmalloc space even when kernel page-table
dumping is enabled
- Tidy up the types used in our early MMU setup code
- Rework rodata= for closer parity with the behaviour on x86
- For CPUs implementing BBML2_NOABORT, utilise block mappings in the
linear map even when rodata= applies to virtual aliases
- Don't re-allocate the virtual region between '_text' and '_stext',
as doing so confused tools parsing /proc/vmcore.
Miscellaneous:
- Clean-up Kconfig menuconfig text for architecture features
- Avoid redundant bitmap_empty() during determination of supported
SME vector lengths
- Re-enable warnings when building the 32-bit vDSO object
- Avoid breaking our eggs at the wrong end.
Perf and PMUs:
- Support for v3 of the Hisilicon L3C PMU
- Support for Hisilicon's MN and NoC PMUs
- Support for Fujitsu's Uncore PMU
- Support for SPE's extended event filtering feature
- Preparatory work to enable data source filtering in SPE
- Support for multiple lanes in the DWC PCIe PMU
- Support for i.MX94 in the IMX DDR PMU driver
- MAINTAINERS update (Thank you, Yicong)
- Minor driver fixes (PERF_IDX2OFF() overflow, CMN register offsets).
Selftests:
- Add basic LSFE check to the existing hwcaps test
- Support nolibc in GCS tests
- Extend SVE ptrace test to pass unsupported regsets and invalid
vector lengths
- Minor cleanups (typos, cosmetic changes).
System registers:
- Fix ID_PFR1_EL1 definition
- Fix incorrect signedness of some fields in ID_AA64MMFR4_EL1
- Sync TCR_EL1 definition with the latest Arm ARM (L.b)
- Be stricter about the input fed into our AWK sysreg generator
script
- Typo fixes and removal of redundant definitions.
ACPI, EFI and PSCI:
- Decouple Arm's "Software Delegated Exception Interface" (SDEI)
support from the ACPI GHES code so that it can be used by platforms
booted with device-tree
- Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
runtime calls
- Fix a node refcount imbalance in the PSCI device-tree code.
CPU Features:
- Ensure register sanitisation is applied to fields in ID_AA64MMFR4
- Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM
guests can reliably query the underlying CPU types from the VMM
- Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
to our context-switching, signal handling and ptrace code"

Pull hardening updates from Kees Cook:
"One notable addition is the creation of the 'transitional' keyword for
kconfig so CONFIG renaming can go more smoothly.
This has been a long-standing deficiency, and with the renaming of
CONFIG_CFI_CLANG to CONFIG_CFI (since GCC will soon have KCFI
support), this came up again.

bcachefs was marked 'externally maintained' in 6.17 but the code
remained to make the transition smoother.
It's now a DKMS module, making the in-kernel code stale, so remove

Pull vfs mount updates from Christian Brauner:
"This contains some work around mount api handling:
- Output the warning message for mnt_too_revealing() triggered during
fsmount() to the fscontext log. This makes it possible for the
mount tool to output appropriate warnings on the command line.
For example, with the newest fsopen()-based mount(8) from
util-linux, the error messages now look like:
# mount -t proc proc /tmp
mount: /tmp: fsmount() failed: VFS: Mount too revealing.
dmesg(1) may have more information after failed mount system call.
- Do not consume fscontext log entries when returning -EMSGSIZE
Userspace generally expects APIs that return -EMSGSIZE to allow for
them to adjust their buffer size and retry the operation.
However, the fscontext log would previously clear the message even
in the -EMSGSIZE case.
Given that it is very cheap for us to check whether the buffer is
too small before we remove the message from the ring buffer, let's
just do that instead.
- Drop an unused argument from do_remount()"

Pull misc vfs updates from Christian Brauner:
"This contains the usual selections of misc updates for this cycle.
Features:
- Add "initramfs_options" parameter to set initramfs mount options.
This allows to add specific mount options to the rootfs to e.g.,
limit the memory size
- Add RWF_NOSIGNAL flag for pwritev2()
Add RWF_NOSIGNAL flag for pwritev2. This flag prevents the SIGPIPE
signal from being raised when writing on disconnected pipes or
sockets. The flag is handled directly by the pipe filesystem and
converted to the existing MSG_NOSIGNAL flag for sockets
- Allow to pass pid namespace as procfs mount option
Ever since the introduction of pid namespaces, procfs has had very
implicit behaviour surrounding them (the pidns used by a procfs
mount is auto-selected based on the mounting process's active
pidns, and the pidns itself is basically hidden once the mount has
been constructed)
This implicit behaviour has historically meant that userspace was
required to do some special dances in order to configure the pidns
of a procfs mount as desired. Examples include:
* In order to bypass the mnt_too_revealing() check, Kubernetes
creates a procfs mount from an empty pidns so that user
namespaced containers can be nested (without this, the nested
containers would fail to mount procfs)
But this requires forking off a helper process because you cannot
just one-shot this using mount(2)
* Container runtimes in general need to fork into a container
before configuring its mounts, which can lead to security issues
in the case of shared-pidns containers (a privileged process in
the pidns can interact with your container runtime process)
While SUID_DUMP_DISABLE and user namespaces make this less of an
issue, the strict need for this due to a minor uAPI wart is kind
of unfortunate
Things would be much easier if there was a way for userspace to
just specify the pidns they want. So this pull request contains
changes to implement a new "pidns" argument which can be set
using fsconfig(2):
fsconfig(procfd, FSCONFIG_SET_FD, "pidns", NULL, nsfd);
fsconfig(procfd, FSCONFIG_SET_STRING, "pidns", "/proc/self/ns/pid", 0);
or classic mount(2) / mount(8):
// mount -t proc -o pidns=/proc/self/ns/pid proc /tmp/proc
mount("proc", "/tmp/proc", "proc", MS_..., "pidns=/proc/self/ns/pid");
Cleanups:
- Remove the last references to EXPORT_OP_ASYNC_LOCK
- Make file_remove_privs_flags() static
- Remove redundant __GFP_NOWARN when GFP_NOWAIT is used
- Use try_cmpxchg() in start_dir_add()
- Use try_cmpxchg() in sb_init_done_wq()
- Replace offsetof() with struct_size() in ioctl_file_dedupe_range()
- Remove vfs_ioctl() export
- Replace rwlock() with spinlock in epoll code as rwlock causes

- Fix spelling mistake
- Always return zero from replace_fd() instead of the file descriptor
number
- Limit the size for copy_file_range() in compat mode to prevent a
signed overflow
- Fix debugfs mount options not being applied
- Verify the inode mode when loading it from disk in minixfs
- Verify the inode mode when loading it from disk in cramfs
- Don't trigger automounts with RESOLVE_NO_XDEV

through automounts, but could still trigger them

tracepoints

Add a dtschema for the ECC engine on the Realtek RTL93xx SoCs.
The engine supports BCH6 and BCH12 parity for 512 byte blocks.
The hardware can make use of interrupts but this is not yet
supported by the driver. From the known datasheets it is
connected to the LXB (lexra bus) and propably depends on its
clock. Provide an optional clock property that can describe
the relation.

Add drm_modes_size_dumb(), a helper to calculate the dumb-buffer
scanline pitch and allocation size. Implementations of struct
drm_driver.dumb_create can call the new helper for their size
computations.
There is currently quite a bit of code duplication among DRM's
memory managers. Each calculates scanline pitch and buffer size
from the given arguments, but the implementations are inconsistent
in how they treat alignment and format support. Later patches will
unify this code on top of drm_mode_size_dumb() as much as possible.
drm_mode_size_dumb() uses existing 4CC format helpers to interpret
the given color mode. This makes the dumb-buffer interface behave
similar the kernel's video= parameter. Current per-driver implementations
again likely have subtle differences or bugs in how they support color
modes.
The dumb-buffer UAPI is only specified for known color modes. These
values describe linear, single-plane RGB color formats or legacy index
formats. Other values should not be specified. But some user space
still does. So for unknown color modes, there are a number of known
exceptions for which drm_mode_size_dumb() calculates the pitch from
the bpp value, as before. All other values work the same but print
an error.

- document additional use cases for DUMB_CREATE2 in TODO list (Tomi)
- fix typos in documentation (Tomi)

- clarify parameters for hardware alignment
- add a TODO item for DUMB_CREATE2

IEEE 802.3ck-2022 defines counters for FEC bins and 802.3df-2024
clarifies it a bit further. Implement reporting interface through as
addition to FEC stats available in ethtool. Drivers can leave bin
counter uninitialized if per-lane values are provided. In this case the
core will recalculate summ for the bin.
