docs/sched_ext: document that cgroup CPU knobs are scheduler-dependent
The scheduler core communicates the initial cpu controller settings to the BPF scheduler through ops.cgroup_init() and reports subsequent changes through the corresponding ops.cgroup_set_*() callbacks. Whether and how a knob takes effect is up to the loaded scheduler: it may implement the corresponding callback partially or not at all, so cpu.max, cpu.weight and friends can silently have no effect. Document this in the basics section of sched-ext.rst. Signed-off-by: Tao Cui <cuitao@kylinos.cn> Reviewed-by: Andrea Righi <arighi@nvidia.com> Signed-off-by: Tejun Heo <tj@kernel.org> |

Docs/admin-guide/cgroup-v2: document BPF scheduler callbacks for cpu.max and cpu.idle
The cpu.weight and cpu.weight.nice entries already state that the files also affect a BPF scheduler through the cgroup_set_weight callback. However, cpu.max, cpu.max.burst and cpu.idle only mention the fair-class scheduler, even though sched_ext implements the cgroup_set_bandwidth (notified with the period/quota from cpu.max and the burst from cpu.max.burst) and cgroup_set_idle callbacks from these interfaces. Mirror the cpu.weight wording for the three entries and generalize the category preamble to refer to the corresponding cgroup_set_* callback so it keeps covering the entries below.

sched_ext: Fix nonexistent field in sched-ext.rst example
The ops.exit() example in sched-ext.rst reads ei->type, but
struct scx_exit_info has never had a type field - the exit reason is
exposed as ei->kind since the struct was introduced. A scheduler
written following the example fails to compile with
error: no member named 'type' in 'struct scx_exit_info'
Use ei->kind.

bpf: Support __arena and __arena__nullable on struct_ops arguments
A struct_ops callback cannot receive an arena pointer directly, so passing one takes two steps. The pointer arrives as a bare u64 that the callback casts, and because the two sides address the arena through different bases it also has to be rebased by hand on the way in. Add the __arena and __arena__nullable stub argument suffixes to make this convenient. The callback declares the parameter as an arena pointer, receives it as a PTR_TO_ARENA register, and dereferences it directly, while the kernel caller just passes the natural kernel arena address (kaddr). The trampoline converts the value while saving the arguments into the BPF ctx, ctx[slot] = (u32)(kaddr - kern_vm_start), so the program never sees a kernel address and nothing rewrites the ctx after the fact. The converted value keeps the upper 32 bits clear as the JITs require of arena pointer registers and behaves like any cast_kern'ed arena pointer, so cast_user recovers the full user-visible address. __arena converts unconditionally and the kernel caller must not pass NULL. __arena__nullable preserves NULL, tested on the full 64-bit kernel pointer, and surfaces to the verifier as PTR_TO_ARENA (but not as a PTR_TO_ARENA | PTR_MAYBE_NULL). The reason is that PTR_TO_ARENA in the program's type state already encompasses NULL-ness, so it is not meaningful to force a NULL check for the program. The composite suffix intentionally ends in __nullable. Classify __arena__nullable before the generic suffix so scalar arena pointees do not take the generic nullable BTF pointer path. This patch adds the generic side. prepare_arg_info() records arena and nullable argument flags in the struct_ops function model, and bpf_tramp_arena_base() returns the arena base for a single-program struct_ops indirect trampoline. Only that trampoline converts: its program's arena is fixed at generation time. Generic trampolines can mix programs with different arenas and reject arena context arguments defensively, which is unreachable today as only struct_ops programs carry them. Architectures that do not implement the conversion are gated out at verification time with bpf_jit_supports_arena_args().

bpf: Support __arena and __arena__nullable kfunc argument suffixes
Passing an arena pointer to a kfunc takes two steps today. There is no arena pointer argument type, so the pointer crosses the boundary as a bare scalar, and the kfunc then offsets it by the arena base and casts it before it can touch the memory. Every such kfunc open-codes the same translation. Add the __arena and __arena__nullable argument suffixes to make this more convenient. The kfunc declares the parameter by its real pointer type and dereferences it directly, with the JIT rebasing the value at the call site, rN = kern_vm_start + (u32)rN. No bounds check is needed: the u32 offset stays within the guard-padded arena kernel mapping, and a fault on an unpopulated page recovers through the per-arena scratch page. A suffixed argument accepts a PTR_TO_ARENA or scalar register, matching global subprog arena arguments. __arena rebases unconditionally, so the kfunc never sees NULL and a value with zero in the low 32 bits arrives as the arena base. __arena__nullable preserves NULL for optional arguments by skipping the rebase when the truncated value, arena offset 0, is zero. Keeping the plain form NULL-free saves the NULL test on every call. The double separator makes the annotations composable: __arena__nullable also ends in __nullable and naturally follows the common nullable argument path. Plain __arena follows that path too for verifier type checking because both forms accept a constant zero; the function-model flag still determines whether the JIT preserves NULL or rebases it to the arena base. This patch adds the verifier side: the suffixes are recognized in check_kfunc_args() and distilled into argument flags in the function model stored in the kfunc descriptor. JITs retrieve the model while emitting the call, avoiding per-call state in insn_aux_data. JITs declare support with bpf_jit_supports_arena_args() and verification fails with -ENOTSUPP elsewhere.

Including fixes from netfilter.
Looks like our attempt to keep the PRs smaller have only prevented
this one from getting even bigger. In the last 9 days there were
405 postings explicitly tagged with [PATCH net], vs 687
with [PATCH net-next]. 37% of posted patches being fixes is pretty
crazy, and that's likely undercounting because LLM "researchers"
more often post fixes without knowing to tag the patches for specific
trees. I don't have historic data.
In any case, we keep adjusting the criteria. The next PR will be smaller.
Current release - regressions:
- net: defer netdev KOBJ_ADD uevent until the device is published,
previously rtnl_lock would serialize the accesses vs publishing
- net: explicitly cancel work to avoid races with ref tracker exit
- qrtr: ns: raise lookup limit to 128
- eth: hns3: fix speed configuration residue after driver reload
Previous releases - regressions:

regressed flows with MSS and scaling_ratio variability
- Revert "net: thunderbolt: Enable end-to-end flow control also
in transmit", broke some platforms (no packets coming thru)
- eth: stmmac: resume PHY before hardware setup when opening
the interface

bpf: Split kfunc map argument into __const_map and __map
Kfuncs used a single '__map' suffix (KF_ARG_PTR_TO_MAP) for two different things: a verifier-known map matched by map_uid against a bound timer/wq/task_work object (bpf_wq_init, bpf_task_work_schedule*), and an opaque 'struct bpf_map *' used only at runtime (bpf_arena_*), which may be a map fd or a PTR_TO_BTF_ID struct bpf_map (e.g. a bpf_map iterator's ctx->map). That combined path only accepted the btf map form due to type confusion. The 'if (!reg->map_ptr)' check reads reg->map_ptr, which aliases reg->btf in the bpf_reg_state union. A PTR_TO_BTF_ID register always has a non-NULL reg->btf, so the guard silently passed and validation fell through to process_kf_arg_ptr_to_btf_id(). It also recorded PTR_TO_BTF_ID info in meta->map, which would be meaningless. Split the annotation to avoid such type confusion and to align with helper: - '__const_map' -> KF_ARG_CONST_MAP_PTR: verifier-known map, handled by process_map_ptr_arg() like helper ARG_CONST_MAP_PTR. - '__map' -> KF_ARG_PTR_TO_BTF_ID: opaque struct bpf_map, validated by process_kf_arg_ptr_to_btf_id(). A map fd still matches via reg2btf_ids[CONST_PTR_TO_MAP], so bpf_arena_alloc_pages(&map) keeps working.

io.latency is documented only in terms of average latency and the avg_lat stat, which matches rotational devices. On non-rotational devices a group misses its target once enough of the IOs in the window individually exceed it, and io.stat reports missed/total rather than avg_lat/win. Describe both cases: how a miss is detected, note that the avg_lat tuning guidance is rotational-only, and update the io.stat field list (mark avg_lat/win as rotational-only, document missed/total).

ovpn: limit keepalive values to one day
Large keepalive values can overflow the delayed-work delay on 32-bit systems, causing the keepalive worker to be repeatedly scheduled. A correct configuration should not require such large keepalive values, and an upper limit of one day is already generous and unnecessary in practice. Limit both the keepalive interval and timeout to 86400 seconds. Signed-off-by: Marco Baffo <marco@mandelbit.com> Signed-off-by: Antonio Quartulli <antonio@openvpn.net> |

KVM: s390: Fall back to short-term pinning in MAP ioctl
FOLL_LONGTERM pinning fails for some memory types, such as file-backed
guest memory. As a result, kvm_s390_adapter_map() returns -EINVAL and
irqfd adapter registration fails even though interrupt delivery could
still work via the existing non-atomic path.
When FOLL_LONGTERM pinning fails, verify that the page is accessible
using a short-term pin instead. If the short-term pin succeeds, unpin
the page and add a map entry with pinned=false to preserve MAP/UNMAP
symmetry. The non-atomic irqfd path already performs short-term pinning
for interrupt delivery, so this restores the previous behavior for
memory that cannot be pinned long-term.
get_map_info() is updated to return NULL for unpinned entries so that
the atomic irqfd fast path falls back to the non-atomic path.
kvm_s390_adapter_unmap() and kvm_s390_unmap_all_adapters() skip dirty
marking and unpin for unpinned entries.
Update Documentation/virt/kvm/devices/s390_flic.rst to reflect the
new MAP/UNMAP behavior.

sched_ext: Bound per-task reenqueues and eject the owning scheduler
Unlike local reenqueues, cap rejections have no repeat limit. A
malfunctioning scheduler can keep re-inserting a task to a cid it lacks caps
on, cycling the task through reject and reenqueue. This was assumed safe
because a task that never runs trips the stall watchdog. However, the
reenqueue irq_work re-arms itself and outranks the timer vector, blocking
everything else on the CPU including stall detection and recovery, until the
NMI hardlockup detector fires.
Local reenqueues already have a repeat cap, SCX_REENQ_LOCAL_MAX_REPEAT,
which needs generalizing to cover all reenqueues. It also has an attribution
problem. Counted per-cpu on root, it tears down the whole hierarchy even
when a sub-scheduler caused the repeated reenqueues.
Generalize by bounding every reenqueue with one per-task counter. reenq_cnt
is bumped in scx_do_enqueue_task() on each SCX_ENQ_REENQ, the single path
every reenqueue producer passes through, and cleared in clr_task_runnable()
when the task is picked to run and in scx_disable_task() when it leaves the
scheduler's control. Past SCX_REENQ_MAX_REPEAT the task's owning scheduler
is ejected with a new SCX_EXIT_ERROR_REENQ and the task is left stranded to
be picked up during sched exit.
The SCX_EV_REENQ_LOCAL_REPEAT event becomes SCX_EV_REENQ_REPEAT, counting
repeat reenqueues from all sources.
v2: Count SCX_EV_REENQ_REPEAT only when a reenqueue leads to another
reenqueue, not on every reenqueue.
v3: - Also clear reenq_cnt in scx_disable_task() so that the count doesn't
carry over to the next owner across sched class switches, scheduler
replacement or sub-scheduler rehoming (Andrea Righi).
- Update the stale SCX_EV_REENQ_LOCAL_REPEAT references in sched-ext.rst
(Andrea Righi).

xsk: reclaim invalid Tx descriptors in ZC batch path
The zero-copy Tx batch parser stops when it encounters an invalid
descriptor. If this happens after one or more continuation descriptors,
the Tx consumer can be advanced past fragments that are neither submitted
to the driver nor returned to userspace through the completion ring.
A similar problem occurs when a packet exceeds xdp_zc_max_segs. The
descriptors consumed up to the limit are released without completion, and
the remaining continuation descriptors can subsequently be interpreted
as the beginning of another packet.
Parse Tx batches in packet units and distinguish descriptors belonging to
complete valid packets from descriptors consumed while draining an
invalid or oversized packet. Return the former to the driver and append
the latter to the CQ address area so userspace can reclaim their UMEM
frames.
Treat a standalone invalid descriptor as a one-descriptor reclaim-only
packet. Advancing the Tx-ring consumer releases the ring slot, but does
not by itself return ownership of the referenced UMEM frame to userspace.
Once draining starts, continue until the packet's end-of-packet
descriptor is consumed. Preserve the drain state on the socket when EOP
has not yet been supplied, so draining can continue during a later call.
Leave incomplete but otherwise valid packets on the Tx ring.
Shared-UMEM pools using multi-buffer Tx also need packet-framed parsing.
Walk their Tx sockets one packet at a time, preserving the existing
per-socket fairness scheme, instead of using the legacy one-descriptor
fallback. Keep that fallback for shared pools that do not use
multi-buffer Tx. Since the drain state is maintained per socket and both
the singular and shared paths can resume an interrupted drain, changing
the socket list from singular to shared requires no special bind-time
transition.
CQ entries are positional, and drivers may complete only part of the Tx
work returned by xsk_tx_peek_release_desc_batch(). Therefore, reclaim-only
entries cannot be published immediately when earlier driver-visible
descriptors are still outstanding.
Track the number of driver-visible CQ entries preceding the reclaim
entries. Let xsk_tx_completed() publish partial hardware Tx completions,
and publish the reclaim entries only after every earlier Tx descriptor
has completed. Complete a reclaim-only batch immediately when there is no
driver-visible work in front of it, and prevent another Tx batch from
being appended while reclaim entries remain pending.
Also cap batch processing by the size of the pool's temporary descriptor
array, as Tx rings belonging to sockets sharing a UMEM may have different
sizes.
This ensures that every invalid Tx descriptor consumed by the ZC batch
path is either submitted to the driver as part of a valid packet or
returned to userspace without violating CQ completion ordering.

KVM: arm64: Reject guest_memfd memslots when the VM has MTE
The user cannot use MTE on VMAs created by mapping a guest_memfd file,
as arch_calc_vm_flag_bits() does not set VM_MTE_ALLOWED.
When creating a guest_memfd backed memslot,
kvm_arch_prepare_memory_region() rejects the memslot if MTE is enabled for
the VM and if guest_memfd has been mapped in a VMA that intersects the
memslot.
However, the documentation for KVM_SET_USER_MEMORY_REGION2 explicitly
states that the only condition for userspace_addr is for it to be a legal
userspace address, but the mapping is not required to be valid nor
populated at memslot creation.
If userspace sets userspace_addr to an address that hasn't been mapped, or
if userspace_addr belongs to a VMA that isn't backed by the guest_memfd
file, or if the VMA doesn't intersect the memslot, memslot creation is
successful and KVM ends up with a VM with MTE and guest_memfd-backed
memslots.
The same happens if the order is reversed: when userspace enables MTE, KVM
does not check if memslots backed by guest_memfd are already present.
Fix both issues by rejecting guest_memfd-backed memslots when MTE is
enabled, and by rejecting MTE when guest_memfd-backed memslots are already
present.

KVM: arm64: vgic: Avoid double-deactivate of IRQs in the nested context
In the nested state, the physical interrupt has already been
deactivated through the HW bit in the LR. The extra deactivation
would be harmless but can hit an errata case on AmpereOne, so
avoid it here.
On AmpereOne, deactivating a physical interrupt through
ICC_DIR_EL1 or ICC_EOIR1_EL1 (depending on EOImode) which is not
active, but is the highest priority pending interrupt causes the
cpu to lose the interrupt pending state and also prevents the
delivery of future interrupts.

netlink: specs: rt-link: convert bridge port flag attributes to u8
A number of IFLA_BRPORT_* attributes are documented in the rt-link spec
as having the "flag" type, i.e. a payload-less NLA_FLAG attribute whose
meaning is presence-only. This does not match the kernel, which emits
these attributes with nla_put_u8() and validates them as NLA_U8 in
br_port_policy[]. The values are not mere presence flags but carry a u8
payload (0/1).
Convert these bridge port attributes from "flag" to "u8" so the spec
reflects the actual wire format.

Pull RISC-V fixes from Paul Walmsley:
"The most notable change involves the rseq kselftest common Makefile
(as it is not RISC-V-specific). The basic approach in the patch
appears similar to one used in the KVM and S390 selftests (grep for
LINUX_TOOL_ARCH_INCLUDE and SUBARCH), and the rseq kselftests pass a
quick build test on x86 after this.

Documentation/bpf: Add BPF signing and enforcement doc
Describe the BPF signing design end to end: why a trusted loader is
needed, the signature(insns || metadata) contract, load-time
verification via fd_array (exclusive + frozen maps), the binary
BPF_SIG_{UNSIGNED,VERIFIED} verdict, and how [BPF] LSMs can enforce
policy on it.
This writes down the contract on the discussion points with the LSM /
integrity folks [0][1]: by the time security_bpf_prog_load() is
called, signature verification has fully completed and covers the
instructions plus the frozen contents of every bound exclusive map;
there is no intermediate "loader verified, payload pending" state
to reason about; and what BPF_SIG_VERIFIED means at each hook is
spelled out explicitly.
