Task states (NONE, INIT, READY, ENABLED) were defined in a separate enum with
unshifted values and then shifted when stored in scx_entity.flags. Simplify by
defining them as pre-shifted values directly in scx_ent_flags and removing the
separate scx_task_state enum. This removes the need for shifting when
reading/writing state values.
scx_get_task_state() now returns the masked flags value directly.
scx_set_task_state() accepts the pre-shifted state value. scx_dump_task()
shifts down for display to maintain readable output.
No functional changes.

scx_bpf_dsq_reenq() currently only supports local DSQs. Extend it to support
user-defined DSQs by adding a deferred re-enqueue mechanism similar to the
local DSQ handling.
Add per-cpu deferred_reenq_user_node/flags to scx_dsq_pcpu and
deferred_reenq_users list to scx_rq. When scx_bpf_dsq_reenq() is called on a
user DSQ, the DSQ's per-cpu node is added to the current rq's deferred list.
process_deferred_reenq_users() then iterates the DSQ using the cursor helpers
and re-enqueues each task.

Factor out cursor-based DSQ iteration from bpf_iter_scx_dsq_next() into
nldsq_cursor_next_task() and the task-lost check from scx_dsq_move() into
nldsq_cursor_lost_task() to prepare for reuse.
As ->priv is only used to record dsq->seq for cursors, update
INIT_DSQ_LIST_CURSOR() to take the DSQ pointer and set ->priv from dsq->seq
so that users don't have to read it manually. Move scx_dsq_iter_flags enum
earlier so nldsq_cursor_next_task() can use SCX_DSQ_ITER_REV.
bypass_lb_cpu() now sets cursor.priv to dsq->seq but doesn't use it.

Add per-CPU data structure to dispatch queues. Each DSQ now has a percpu
scx_dsq_pcpu which contains a back-pointer to the DSQ. This will be used by
future changes to implement per-CPU reenqueue tracking for user DSQs.
init_dsq() now allocates the percpu data and can fail, so it returns an
error code. All callers are updated to handle failures. exit_dsq() is added
to free the percpu data and is called from all DSQ cleanup paths.
In scx_bpf_create_dsq(), init_dsq() is called before rcu_read_lock() since
alloc_percpu() requires GFP_KERNEL context, and dsq->sched is set
afterwards.
v2: Fix err_free_pcpu to only exit_dsq() initialized bypass DSQs (Andrea

The else-if and else branches in rht_key_get_hash() both compute a hash
using either params.hashfn or jhash, differing only in the source of
key_len (params.key_len vs ht->p.key_len). Merge the two branches into
one by using the ternary `params.key_len ?: ht->p.key_len` to select
the key length, removing the duplicated logic.
This also improves the performance of the else branch which previously
always used jhash and never fell through to jhash2. This branch is going
to be used by BPF resizable hashmap, which wraps rhashtable:

Commit c7159e960f14 ("usbnet: limit max_mtu based on device's hard_mtu")
capped net->max_mtu to the device's hard_mtu in usbnet_probe(). While
this correctly prevents oversized packets on standard USB network
devices, it breaks the qmi_wwan driver.
qmi_wwan relies on userspace (e.g. ModemManager) setting a large MTU on
the wwan0 interface to configure rx_urb_size via usbnet_change_mtu().
QMI modems negotiate USB transfer sizes of 16,383 or 32,767 bytes, and
the USB receive buffers must be sized accordingly. With max_mtu capped
to hard_mtu (~1500 bytes), userspace can no longer raise the MTU, the
receive buffers remain small, and download speeds drop from >300 Mbps
to ~0.8 Mbps.
Introduce a FLAG_NOMAXMTU driver flag that allows individual usbnet
drivers to opt out of the max_mtu cap. Set this flag in qmi_wwan's
driver_info structures to restore the previous behavior for QMI devices,
while keeping the safety fix in place for all other usbnet drivers.

The preceding changes implemented the framework to support cgroup
sub-scheds and updated scheduling paths and kfuncs so that they have
minimal but working support for sub-scheds. However, actual sub-sched
enabling/disabling hasn't been implemented yet and all tasks stayed on
scx_root.
Implement cgroup sub-sched enabling and disabling to actually activate
sub-scheds:
- Both enable and disable operations bypass only the tasks in the subtree
of the child being enabled or disabled to limit disruptions.
- When enabling, all candidate tasks are first initialized for the child
sched. Once that succeeds, the tasks are exited for the parent and then
switched over to the child. This adds a bit of complication but
guarantees that child scheduler failures are always contained.
- Disabling works the same way in the other direction. However, when the
parent may fail to initialize a task, disabling is propagated up to the
parent. While this means that a parent sched fail due to a child sched
event, the failure can only originate from the parent itself (its
ops.init_task()). The only effect a malfunctioning child can have on the
parent is attempting to move the tasks back to the parent.
After this change, although not all the necessary mechanisms are in place
yet, sub-scheds can take control of their tasks and schedule them.

In preparation of multiple scheduler support, add p->scx.sched which points
to the scx_sched instance that the task is scheduled by, which is currently
always scx_root. Add scx_task_sched[_rcu]() accessors which return the
associated scx_sched of the specified task and replace the raw scx_root
dereferences with it where applicable. scx_task_on_sched() is also added to
test whether a given task is on the specified sched.
As scx_root is still the only scheduler, this shouldn't introduce
user-visible behavior changes.

A system often runs multiple workloads especially in multi-tenant server
environments where a system is split into partitions servicing separate
more-or-less independent workloads each requiring an application-specific
scheduler. To support such and other use cases, sched_ext is in the process
of growing multiple scheduler support.
When partitioning a system in terms of CPUs for such use cases, an
oft-taken approach is hard partitioning the system using cpuset. While it
would be possible to tie sched_ext multiple scheduler support to cpuset
partitions, such an approach would have fundamental limitations stemming
from the lack of dynamism and flexibility.
Users often don't care which specific CPUs are assigned to which workload
and want to take advantage of optimizations which are enabled by running
workloads on a larger machine - e.g. opportunistic over-commit, improving
latency critical workload characteristics while maintaining bandwidth
fairness, employing control mechanisms based on different criteria than
on-CPU time for e.g. flexible memory bandwidth isolation, packing similar
parts from different workloads on same L3s to improve cache efficiency,
and so on.
As this sort of dynamic behaviors are impossible or difficult to implement
with hard partitioning, sched_ext is implementing cgroup sub-sched support
where schedulers can be attached to the cgroup hierarchy and a parent
scheduler is responsible for controlling the CPUs that each child can use
at any given moment. This makes CPU distribution dynamically controlled by
BPF allowing high flexibility.
This patch adds the skeletal sched_ext cgroup sub-sched support:
- sched_ext_ops.sub_cgroup_id and .sub_attach/detach() are added. Non-zero
sub_cgroup_id indicates that the scheduler is to be attached to the
identified cgroup. A sub-sched is attached to the cgroup iff the nearest
ancestor scheduler implements .sub_attach() and grants the attachment. Max
nesting depth is limited by SCX_SUB_MAX_DEPTH.
- When a scheduler exits, all its descendant schedulers are exited
together. Also, cgroup.scx_sched added which points to the effective
scheduler instance for the cgroup. This is updated on scheduler
init/exit and inherited on cgroup online. When a cgroup is offlined, the
attached scheduler is automatically exited.
- Sub-sched support is gated on CONFIG_EXT_SUB_SCHED which is
automatically enabled if both SCX and cgroups are enabled. Sub-sched
support is not tied to the CPU controller but rather the cgroup
hierarchy itself. This is intentional as the support for cpu.weight and
cpu.max based resource control is orthogonal to sub-sched support. Note
that CONFIG_CGROUPS around cgroup subtree iteration support for
scx_task_iter is replaced with CONFIG_EXT_SUB_SCHED for consistency.
- This allows loading sub-scheds and most framework operations such as
propagating disable down the hierarchy work. However, sub-scheds are not
operational yet and all tasks stay with the root sched. This will serve
as the basis for building up full sub-sched support.
- DSQs point to the scx_sched they belong to.
- scx_qmap is updated to allow attachment of sub-scheds and also serving
as sub-scheds.
- scx_is_descendant() is added but not yet used in this patch. It is used by
later changes in the series and placed here as this is where the function
belongs.

- Use READ_ONCE() for reading refill queue entries
- Reject SEND_VECTORIZED for fixed buffer sends, as it isn't

The ext4_load_inode trace event uses %lld (signed) to print the ino
field which is u64 (unsigned). Use %llu instead.
Signed-off-by: Christian Brauner <brauner@kernel.org>

On 32-bit architectures, unsigned long is only 32 bits wide, which
causes 64-bit inode numbers to be silently truncated. Several
filesystems (NFS, XFS, BTRFS, etc.) can generate inode numbers that
exceed 32 bits, and this truncation can lead to inode number collisions
and other subtle bugs on 32-bit systems.
Change the type of inode->i_ino from unsigned long to u64 to ensure that
inode numbers are always represented as 64-bit values regardless of
architecture. Update all format specifiers treewide from %lu/%lx to
%llu/%llx to match the new type, along with corresponding local variable
types.
This is the bulk treewide conversion. Earlier patches in this series
handled trace events separately to allow trace field reordering for
better struct packing on 32-bit.

inode->i_ino is being converted to a u64. sock.sk_ino (which caches the
inode number) must also be widened to avoid truncation on 32-bit
architectures where unsigned long is only 32 bits.
Change sk_ino from unsigned long to u64, and update the return type
of sock_i_ino() to match. Fix all format strings that print the
result of sock_i_ino() (%lu -> %llu), and widen the intermediate
variables and function parameters in the diag modules that were
using int to hold the inode number.
Note that the UAPI socket diag structures (inet_diag_msg.idiag_inode,
unix_diag_msg.udiag_ino, etc.) are all __u32 and cannot be changed
without breaking the ABI. The assignments to those fields will
silently truncate, which is the existing behavior.

inode->i_ino is being widened from unsigned long to u64. The audit
subsystem uses unsigned long ino in struct fields, function parameters,
and local variables that store inode numbers from arbitrary filesystems.
On 32-bit platforms this truncates inode numbers that exceed 32 bits,
which will cause incorrect audit log entries and broken watch/mark
comparisons.
Widen all audit ino fields, parameters, and locals to u64, and update
the inode format string from %lu to %llu to match.

Change the inode hash/lookup VFS API functions to accept u64 parameters
instead of unsigned long for inode numbers and hash values. This is
preparation for widening i_ino itself to u64, which will allow
filesystems to store full 64-bit inode numbers on 32-bit architectures.
Since unsigned long implicitly widens to u64 on all architectures, this
change is backward-compatible with all existing callers.

S1G defines use of NDP Block Ack (BA) for aggregation, requiring negotiation
of NDP ADDBA/DELBA action frames. If the S1G recipient supports HT-immediate
block ack, the sender must send an NDP ADDBA Request indicating it expects
only NDP BlockAck frames for the agreement.
Introduce support for NDP ADDBA and DELBA exchange in mac80211. The
implementation negotiates the BA mechanism during setup based on station
capabilities and driver support (IEEE80211_HW_SUPPORTS_NDP_BLOCKACK).
If negotiation fails due to mismatched expectations, a rejection with status code
WLAN_STATUS_REJECTED_NDP_BLOCK_ACK_SUGGESTED is returned as per IEEE 802.11-2024.

The action code actually serves to identify the type of action
frame, so it really isn't part of the per-type structure. Pull
it out and have it in the general action frame format.
In theory, whether or not the action code is present in this
way is up to each category, but all categories that are defined
right now all have that value.
While at it, and since this change requires changing all users,
remove the 'u' and make it an anonymous union in this case, so
that all code using this changes.
Change IEEE80211_MIN_ACTION_SIZE to take an argument which says
how much of the frame is needed, e.g. category, action_code or
the specific frame type that's defined in the union. Again this
also ensures that all code is updated.
In some cases, fix bugs where the SKB length was checked after
having accessed beyond the checked length, in particular in FTM
code, e.g. ieee80211_is_ftm().

inet_ehashfn() and inet6_ehashfn() initialise random secrets
on the first call by net_get_random_once().
While the init part is patched out using static keys, with
CONFIG_STACKPROTECTOR_STRONG=y, this causes a compiler to
generate a stack canary due to an automatic variable,
unsigned long ___flags, in the DO_ONCE() macro being passed
to __do_once_start().
With FDO, this is visible in __inet_lookup_established() and
__inet6_lookup_established() too.
Let's initialise the secrets by get_random_sleepable_once()
in the slow paths: inet_hash() for listen(), and
inet_hash_connect() and inet6_hash_connect() for connect().
Note that IPv6 listener will initialise both IPv4 & IPv6 secrets
in inet_hash() for IPv4-mapped IPv6 address.
With the patch, the stack size is reduced by 16 bytes (___flags
+ a stack canary) and NOPs for the static key go away.
Before: __inet6_lookup_established()
...

sub $0x38,%rsp # stack is 56 bytes
mov %edx,%ebx # sport
mov %gs:0x299419f(%rip),%rax # load stack canary
