ublk: refactor common helper ublk_shmem_remove_ranges()
Extract the shared walk+erase+unpin+kfree loop into ublk_shmem_remove_ranges(). When buf_index >= 0, only ranges matching that index are removed; when buf_index < 0, all ranges are removed. Also extract ublk_unpin_range_pages() to share the page unpinning loop. Convert both __ublk_ctrl_unreg_buf() and ublk_buf_cleanup() to use the new helper.

ublk: fix maple tree lockdep warning in ublk_buf_cleanup
ublk_buf_cleanup() iterates the maple tree with mas_for_each()
without holding mas_lock, triggering a lockdep splat on
CONFIG_PROVE_RCU kernels since mas_find() internally uses
rcu_dereference_check() which requires either RCU or the tree lock.
Fix by holding mas_lock around the iteration, and call mas_erase()
before freeing each range to avoid dangling pointers in the tree.

selftests: ublk: add ublk auto integrity test
The end-to-end integrity ublk selftest test_integrity_02 requires a relatively recent fio version to support I/O with integrity buffers. Add a version test_integrity_03 that uses the block layer's auto integrity path instead. The auto integrity code doesn't check the application tag, and doesn't indicate the bad guard/ref tag (just returns EILSEQ). But it's a good smoke-test of the ublk integrity code and provides coverage of the auto integrity path as well.

block: only restrict bio allocation gfp mask asked to block
If the caller is asking for a non-blocking allocation, we should not

block: relax pgmap check in bio_add_page for compatible zone device pages
bio_add_page() and bio_integrity_add_page() reject pages from different
dev_pagemaps entirely, returning 0 even when those pages have compatible
DMA mapping requirements. This forces callers to start a new bio when
buffers span pgmap boundaries, even though the pages could safely coexist
as separate bvec entries.
This matters for guests where memory is registered through
devm_memremap_pages() with MEMORY_DEVICE_GENERIC in multiple calls,
creating separate dev_pagemaps for each chunk. When a direct I/O buffer
spans two such chunks, bio_add_page() rejects the second page, forcing an
unnecessary bio split or I/O failure.
Introduce zone_device_pages_compatible() in blk.h to check whether two
pages can coexist in the same bio as separate bvec entries. The block DMA
iterator (blk_dma_map_iter_start) caches the P2PDMA mapping state from the
first segment and applies it to all others, so P2PDMA pages from different
pgmaps must not be mixed, and neither must P2PDMA and non-P2PDMA pages.
All other combinations (MEMORY_DEVICE_GENERIC pages from different pgmaps,
or MEMORY_DEVICE_GENERIC with normal RAM) use the same dma_map_phys path
and are safe.
Replace the blanket zone_device_pages_have_same_pgmap() rejection with
zone_device_pages_compatible(), while keeping
zone_device_pages_have_same_pgmap() as a merge guard.
Pages from different pgmaps can be added as separate bvec entries but
must not be coalesced into the same segment, as that would make
it impossible to recover the correct pgmap via page_pgmap().

block: add pgmap check to biovec_phys_mergeable
biovec_phys_mergeable() is used by the request merge, DMA mapping,
and integrity merge paths to decide if two physically contiguous
bvec segments can be coalesced into one. It currently has no check
for whether the segments belong to different dev_pagemaps.
When zone device memory is registered in multiple chunks, each chunk
gets its own dev_pagemap. A single bio can legitimately contain
bvecs from different pgmaps -- iov_iter_extract_bvecs() breaks at
pgmap boundaries but the outer loop in bio_iov_iter_get_pages()
continues filling the same bio. If such bvecs are physically
contiguous, biovec_phys_mergeable() will coalesce them, making it
impossible to recover the correct pgmap for the merged segment
via page_pgmap().
Add a zone_device_pages_have_same_pgmap() check to prevent merging
bvec segments that span different pgmaps.

floppy: fix reference leak on platform_device_register() failure
When platform_device_register() fails in do_floppy_init(), the embedded
struct device in floppy_device[drive] has already been initialized by
device_initialize(), but the failure path jumps to out_remove_drives
without dropping the device reference for the current drive.
Previously registered floppy devices are cleaned up in out_remove_drives,
but the device for the drive that fails registration is not, leading to
a reference leak.
The issue was identified by a static analysis tool I developed and
confirmed by manual review. Fix this by calling put_device() for the
current floppy device before jumping to the common cleanup path.

ublk: use unchecked copy helpers for bio page data
Bio pages may originate from slab caches that lack a usercopy region
(e.g. jbd2 frozen metadata buffers allocated via jbd2_alloc()).
When CONFIG_HARDENED_USERCOPY is enabled, copy_to_iter() calls
check_copy_size() which rejects these slab pages, triggering a
kernel BUG in usercopy_abort().
This is a false positive: the data is ordinary block I/O content —
the same data the loop driver writes to its backing file via
vfs_iter_write(). The bvec length is always trusted, so the size
check in check_copy_size() is not needed either.
Switch to _copy_to_iter()/_copy_from_iter() which skip the
check_copy_size() wrapper while the underlying copy_to_user()
remains unchanged.

sched_ext: Changes for v7.1
- Cgroup sub-scheduler groundwork. Multiple BPF schedulers can be attached to cgroups and the dispatch path is made hierarchical. This involves substantial restructuring of the core dispatch, bypass, watchdog, and dump paths to be per-scheduler, along with new infrastructure for scheduler ownership enforcement, lifecycle management, and cgroup subtree iteration. The enqueue path is not yet updated and will follow in a later cycle. - scx_bpf_dsq_reenq() generalized to support any DSQ including remote local DSQs and user DSQs. Built on top of this, SCX_ENQ_IMMED guarantees that tasks dispatched to local DSQs either run immediately or get reenqueued back through ops.enqueue(), giving schedulers tighter control over queueing latency. Also useful for opportunistic CPU sharing across sub-schedulers. - ops.dequeue() was only invoked when the core knew a task was in BPF data structures, missing scheduling property change events and skipping callbacks for non-local DSQ dispatches from ops.select_cpu(). Fixed to guarantee exactly one ops.dequeue() call when a task leaves BPF scheduler custody. - Kfunc access validation moved from runtime to BPF verifier time, removing runtime mask enforcement. - Idle SMT sibling prioritization in the idle CPU selection path. - Documentation, selftest, and tooling updates.

Pull pid_namespace updates from Christian Brauner:
- pid_namespace: make init creation more flexible
Annotate ->child_reaper accesses with {READ,WRITE}_ONCE() to protect
the unlocked readers from cpu/compiler reordering, and enforce that
pid 1 in a pid namespace is always the first allocated pid (the
set_tid path already required this).
On top of that, allow opening pid_for_children before the pid
namespace init has been created. This lets one process create the pid
namespace and a different process create the init via setns(), which
makes clone3(set_tid) usable in all cases evenly and is particularly
useful to CRIU when restoring nested containers.
A new selftest covers both the basic create-pidns-then-init flow and
the cross-process variant, and a MAINTAINERS entry for the pid
namespace code is added.
- unrelated signal cleanup: update outdated comment for the removed
freezable_schedule()

Merge tag 'vfs-7.1-rc1.mount.v2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs mount updates from Christian Brauner:
- Add FSMOUNT_NAMESPACE flag to fsmount() that creates a new mount
namespace with the newly created filesystem attached to a copy of the
real rootfs. This returns a namespace file descriptor instead of an
O_PATH mount fd, similar to how OPEN_TREE_NAMESPACE works for
open_tree().
This allows creating a new filesystem and immediately placing it in a
new mount namespace in a single operation, which is useful for
container runtimes and other namespace-based isolation mechanisms.
This accompanies OPEN_TREE_NAMESPACE and avoids a needless detour via
OPEN_TREE_NAMESPACE to get the same effect. Will be especially useful
when you mount an actual filesystem to be used as the container
rootfs.
- Currently, creating a new mount namespace always copies the entire
mount tree from the caller's namespace. For containers and sandboxes
that intend to build their mount table from scratch this is wasteful:
they inherit a potentially large mount tree only to immediately tear
it down.
This series adds support for creating a mount namespace that contains
only a clone of the root mount, with none of the child mounts. Two
new flags are introduced:
- CLONE_EMPTY_MNTNS (0x400000000) for clone3(), using the 64-bit flag space
- UNSHARE_EMPTY_MNTNS (0x00100000) for unshare()
Both flags imply CLONE_NEWNS. The resulting namespace contains a
single nullfs root mount with an immutable empty directory. The
intended workflow is to then mount a real filesystem (e.g., tmpfs)
over the root and build the mount table from there.
- Allow MOVE_MOUNT_BENEATH to target the caller's rootfs, allowing to
switch out the rootfs without pivot_root(2).
The traditional approach to switching the rootfs involves
pivot_root(2) or a chroot_fs_refs()-based mechanism that atomically
updates fs->root for all tasks sharing the same fs_struct. This has
consequences for fork(), unshare(CLONE_FS), and setns().
This series instead decomposes root-switching into individually
atomic, locally-scoped steps:
fd_tree = open_tree(-EBADF, "/newroot", OPEN_TREE_CLONE | OPEN_TREE_CLOEXEC);
fchdir(fd_tree);
move_mount(fd_tree, "", AT_FDCWD, "/", MOVE_MOUNT_BENEATH | MOVE_MOUNT_F_EMPTY_PATH);
chroot(".");
umount2(".", MNT_DETACH);
Since each step only modifies the caller's own state, the
fork/unshare/setns races are eliminated by design.
A key step to making this possible is to remove the locked mount
restriction. Originally MOVE_MOUNT_BENEATH doesn't support mounting
beneath a mount that is locked. The locked mount protects the
underlying mount from being revealed. This is a core mechanism of
unshare(CLONE_NEWUSER | CLONE_NEWNS). The mounts in the new mount
namespace become locked. That effectively makes the new mount table
useless as the caller cannot ever get rid of any of the mounts no
matter how useless they are.
We can lift this restriction though. We simply transfer the locked
property from the top mount to the mount beneath. This works because
what we care about is to protect the underlying mount aka the parent.
The mount mounted between the parent and the top mount takes over the
job of protecting the parent mount from the top mount mount. This
leaves us free to remove the locked property from the top mount which
can consequently be unmounted:
unshare(CLONE_NEWUSER | CLONE_NEWNS)
and we inherit a clone of procfs on /proc then currently we cannot
unmount it as:
umount -l /proc
will fail with EINVAL because the procfs mount is locked.
After this series we can now do:
mount --beneath -t tmpfs tmpfs /proc
umount -l /proc
after which a tmpfs mount has been placed beneath the procfs mount.
The tmpfs mount has become locked and the procfs mount has become
unlocked.
This means you can safely modify an inherited mount table after
unprivileged namespace creation.
Afterwards we simply make it possible to move a mount beneath the
rootfs allowing to upgrade the rootfs.
Removing the locked restriction makes this very useful for containers
created with unshare(CLONE_NEWUSER | CLONE_NEWNS) to reshuffle an
inherited mount table safely and MOVE_MOUNT_BENEATH makes it possible
to switch out the rootfs instead of using the costly pivot_root(2).

Networking changes for 7.1.
Core & protocols
----------------
- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP.
- Number of code moves to help the compiler with inlining.
Avoid output arguments for returning drop reason where possible.
- Rework drop handling within qdiscs to include more metadata
about the reason and dropping qdisc in the tracepoints.
- Remove the rtnl_lock use from IP Multicast Routing.
- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two.
- Report TCP delayed ack timer information via socket diag.
- Add ip_local_port_step_width sysctl to allow distributing the randomly
selected ports more evenly throughout the allowed space.
- Add support for per-route tunsrc in IPv6 segment routing.
- Start work of switching sockopt handling to iov_iter.
- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up.
- Support MSG_EOR in MPTCP.
- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage.
- Remove UDP-Lite support (as announced in 2023).
- Remove support for building IPv6 as a module.
Remove the now unnecessary function calling indirection.
Cross-tree stuff
----------------
- Move Michael MIC code from generic crypto into wireless,
it's considered insecure but some WiFi networks still need it.
Netfilter
---------
- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.
Florian W reports this gets us ~13% higher packet rate.
- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex.
- Add more opinionated input validation to lower security exposure.
- Make IPVS hash tables to be per-netns and resizable.
Wireless
--------
- Finished assoc frame encryption/EPPKE/802.1X-over-auth.
- Radar detection improvements.
- Add 6 GHz incumbent signal detection APIs.
- Multi-link support for FILS, probe response templates and
client probing.
- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware.
Driver API
----------
- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs.
- Add standard counters for reporting pause storm events
(implement in mlx5 and fbnic).
- Add configuration API for completion writeback buffering
(implement in mana).
- Support driver-initiated change of RSS context sizes.
- Support DPLL monitoring input frequency (implement in zl3073x).
- Support per-port resources in devlink (implement in mlx5).
Misc
----
- Expand the YAML spec for Netfilter.

Pull bpf updates from Alexei Starovoitov:
- Welcome new BPF maintainers: Kumar Kartikeya Dwivedi, Eduard
Zingerman while Martin KaFai Lau reduced his load to Reviwer.
- Lots of fixes everywhere from many first time contributors. Thank you
All.
- Diff stat is dominated by mechanical split of verifier.c into
multiple components:
- backtrack.c: backtracking logic and jump history
- states.c: state equivalence
- cfg.c: control flow graph, postorder, strongly connected
components
- liveness.c: register and stack liveness
- fixups.c: post-verification passes: instruction patching, dead
code removal, bpf_loop inlining, finalize fastcall
8k line were moved. verifier.c still stands at 20k lines.
Further refactoring is planned for the next release.
- Replace dynamic stack liveness with static stack liveness based on
data flow analysis.
This improved the verification time by 2x for some programs and
equally reduced memory consumption. New logic is in liveness.c and
supported by constant folding in const_fold.c (Eduard Zingerman,
Alexei Starovoitov)
- Introduce BTF layout to ease addition of new BTF kinds (Alan Maguire)
- Use kmalloc_nolock() universally in BPF local storage (Amery Hung)
- Fix several bugs in linked registers delta tracking (Daniel Borkmann)
- Improve verifier support of arena pointers (Emil Tsalapatis)
- Improve verifier tracking of register bounds in min/max and tnum
domains (Harishankar Vishwanathan, Paul Chaignon, Hao Sun)
- Further extend support for implicit arguments in the verifier (Ihor
Solodrai)
- Add support for nop,nop5 instruction combo for USDT probes in libbpf
(Jiri Olsa)
- Support merging multiple module BTFs (Josef Bacik)
- Extend applicability of bpf_kptr_xchg (Kaitao Cheng)
- Retire rcu_trace_implies_rcu_gp() (Kumar Kartikeya Dwivedi)
- Support variable offset context access for 'syscall' programs (Kumar
Kartikeya Dwivedi)
- Migrate bpf_task_work and dynptr to kmalloc_nolock() (Mykyta
Yatsenko)
- Fix UAF in in open-coded task_vma iterator (Puranjay Mohan)

linux_kselftest-kunit-7.1-rc1
Fixes kunit tool to
-- terminate kernel under test on SIGINT when it catches SIGINT
to make sure the TTY isn't messed up and terminate the running
kernel.
-- recommend --raw_output=all when KTAP header isn't found in the kernel
output, it's useful to re-run the test with --raw_output=all to find
out the reasons why the test didn't complete.
-- skip stty when stdin is not a tty to avoid writing noise to stderr.
-- show suites when user runs --list_suites option instead of entire
list of tests to make the output user friendly and concise.

Modules changes for v7.1-rc1
Kernel symbol flags:
- Replace the separate *_gpl symbol sections (__ksymtab_gpl and
__kcrctab_gpl) with a unified symbol table and a new
__kflagstab section. This section stores symbol flags, such as
the GPL-only flag, as an 8-bit bitset for each exported symbol.
This is a cleanup that simplifies symbol lookup in the module
loader by avoiding table fragmentation and will allow a cleaner
way to add more flags later if needed.
Module signature UAPI:
- Move struct module_signature to the UAPI headers to allow reuse
by tools outside the kernel proper, such as kmod and
scripts/sign-file. This also renames a few constants for clarity
and drops unused signature types as preparation for hash-based
module integrity checking work that's in progress.
Sysfs:
- Add a /sys/module/<module>/import_ns sysfs attribute to show
the symbol namespaces imported by loaded modules. This makes it
easier to verify driver API access at runtime on systems that
care about such things (e.g. Android).
Cleanups and fixes:
- Force sh_addr to 0 for all sections in module.lds. This prevents
non-zero section addresses when linking modules with ld.bfd -r,
which confused elfutils.
- Fix a memory leak of charp module parameters on module unload
when the kernel is configured with CONFIG_SYSFS=n.
- Override the -EEXIST error code returned by module_init() to
userspace. This prevents confusion with the errno reserved by
the module loader to indicate that a module is already loaded.
- Simplify the warning message and drop the stack dump on positive
returns from module_init().
- Drop unnecessary extern keywords from function declarations and
synchronize parse_args() arguments with their implementation.

arm64 updates for 7.1:
Core features:
- Add support for FEAT_LSUI, allowing futex atomic operations without
toggling Privileged Access Never (PAN)
- Further refactor the arm64 exception handling code towards the
generic entry infrastructure
- Optimise __READ_ONCE() with CONFIG_LTO=y and allow alias analysis
through it
Memory management:
- Refactor the arm64 TLB invalidation API and implementation for better
control over barrier placement and level-hinted invalidation
- Enable batched TLB flushes during memory hot-unplug
- Fix rodata=full block mapping support for realm guests (when
BBML2_NOABORT is available)
Perf and PMU:
- Add support for a whole bunch of system PMUs featured in NVIDIA's
Tegra410 SoC (cspmu extensions for the fabric and PCIe, new drivers
for CPU/C2C memory latency PMUs)
- Clean up iomem resource handling in the Arm CMN driver
- Fix signedness handling of AA64DFR0.{PMUVer,PerfMon}
MPAM (Memory Partitioning And Monitoring):
- Add architecture context-switch and hiding of the feature from KVM
- Add interface to allow MPAM to be exposed to user-space using resctrl
- Add errata workaround for some existing platforms
- Add documentation for using MPAM and what shape of platforms can use
resctrl
Miscellaneous:
- Check DAIF (and PMR, where relevant) at task-switch time
- Skip TFSR_EL1 checks and barriers in synchronous MTE tag check mode
(only relevant to asynchronous or asymmetric tag check modes)
- Remove a duplicate allocation in the kexec code
- Remove redundant save/restore of SCS SP on entry to/from EL0
- Generate the KERNEL_HWCAP_ definitions from the arm64 hwcap
descriptions
- Add kselftest coverage for cmpbr_sigill()
- Update sysreg definitions

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
"The biggest changes are MPAM enablement in drivers/resctrl and new PMU
support under drivers/perf.
On the core side, FEAT_LSUI lets futex atomic operations with EL0
permissions, avoiding PAN toggling.
The rest is mostly TLB invalidation refactoring, further generic entry
work, sysreg updates and a few fixes.
