All bind_class callbacks are directly returned when n arg is empty.

IEEE 802.1Q clause 12.29.1.1 "The queueMaxSDUTable structure and data
types" and 8.6.8.4 "Enhancements for scheduled traffic" talk about the
existence of a per traffic class limitation of maximum frame sizes, with
a fallback on the port-based MTU.
As far as I am able to understand, the 802.1Q Service Data Unit (SDU)
represents the MAC Service Data Unit (MSDU, i.e. L2 payload), excluding
any number of prepended VLAN headers which may be otherwise present in
the MSDU. Therefore, the queueMaxSDU is directly comparable to the
device MTU (1500 means L2 payload sizes are accepted, or frame sizes of
1518 octets, or 1522 plus one VLAN header). Drivers which offload this
are directly responsible of translating into other units of measurement.
To keep the fast path checks optimized, we keep 2 arrays in the qdisc,
one for max_sdu translated into frame length (so that it's comparable to
skb->len), and another for offloading and for dumping back to the user.

When adding optional new features to Qdisc offloads, existing drivers
must reject the new configuration until they are coded up to act on it.
Since modifying all drivers in lockstep with the changes in the Qdisc
can create problems of its own, it would be nice if there existed an
automatic opt-in mechanism for offloading optional features.
Jakub proposes that we multiplex one more kind of call through
ndo_setup_tc(): one where the driver populates a Qdisc-specific
capability structure.
First user will be taprio in further changes. Here we are introducing
the definitions for the base functionality.

To work around a misbehavior of the compiler's ability to see into
composite flexible array structs (as detailed in the coming memcpy()
hardening series[1]), use unsafe_memcpy(), as the sizing,
bounds-checking, and allocation are all very tightly coupled here.
This silences the false-positive reported by syzbot:
memcpy: detected field-spanning write (size 80) of single field "&n->sel" at net/sched/cls_u32.c:1043 (size 16)

taprio_dev_notifier() subscribes to netdev state changes in order to
determine whether interfaces which have a taprio root qdisc have changed
their link speed, so the internal calculations can be adapted properly.
The 'qdev' temporary variable serves no purpose, because we just use it
only once, and can just as well use qdisc_dev(q->root) directly (or the
"dev" that comes from the netdev notifier; this is because qdev is only
interesting if it was the subject of the state change, _and_ its root
qdisc belongs in the taprio list).
The 'found' variable also doesn't really serve too much of a purpose
either; we can just call taprio_set_picos_per_byte() within the loop,
and exit immediately afterwards.

Since commit 13511704f8d7 ("net: taprio offload: enforce qdisc to netdev
queue mapping"), taprio_dequeue_soft() and taprio_peek_soft() are de
facto the only implementations for Qdisc_ops :: dequeue and Qdisc_ops ::
peek that taprio provides.
This is because in full offload mode, __dev_queue_xmit() will select a
txq->qdisc which is never root taprio qdisc. So if nothing is enqueued
in the root qdisc, it will never be run and nothing will get dequeued
from it.
Therefore, we can remove the private indirection from taprio, and always
point Qdisc_ops :: dequeue to taprio_dequeue_soft (now simply named
taprio_dequeue) and Qdisc_ops :: peek to taprio_peek_soft (now simply
named taprio_peek).

taprio_enqueue
Since commit 13511704f8d7 ("net: taprio offload: enforce qdisc to netdev
queue mapping"), __dev_queue_xmit() will select a txq->qdisc for the
full offload case of taprio which isn't the root taprio qdisc, so
qdisc enqueues will never pass through taprio_enqueue().
That commit already introduced one safety precaution check for
FULL_OFFLOAD_IS_ENABLED(); a second one is really not needed, so
simplify the conditional for entering into the GSO segmentation logic.
Also reword the comment a little, to appear more natural after the code
change.

The locking in taprio_offload_config_changed() is wrong (but also
inconsequentially so). The current_entry_lock does not serialize changes
to the admin and oper schedules, only to the current entry. In fact, the
rtnl_mutex does that, and that is taken at the time when taprio_change()
is called.
Replace the rcu_dereference_protected() method with the proper RCU
annotation, and drop the unnecessary spin lock.

taprio can only operate as root qdisc, and to that end, there exists the
following check in taprio_init(), just as in mqprio:
if (sch->parent != TC_H_ROOT)
return -EOPNOTSUPP;
And indeed, when we try to attach taprio to an mqprio child, it fails as
expected:
$ tc qdisc add dev swp0 root handle 1: mqprio num_tc 8 \
map 0 1 2 3 4 5 6 7 \
queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 hw 0
$ tc qdisc replace dev swp0 parent 1:2 taprio num_tc 8 \
map 0 1 2 3 4 5 6 7 \
queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \
base-time 0 sched-entry S 0x7f 990000 sched-entry S 0x80 100000 \
flags 0x0 clockid CLOCK_TAI
Error: sch_taprio: Can only be attached as root qdisc.
(extack message added by me)
But when we try to attach a taprio child to a taprio root qdisc,
surprisingly it doesn't fail:
$ tc qdisc replace dev swp0 root handle 1: taprio num_tc 8 \
map 0 1 2 3 4 5 6 7 queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \
base-time 0 sched-entry S 0x7f 990000 sched-entry S 0x80 100000 \
flags 0x0 clockid CLOCK_TAI
$ tc qdisc replace dev swp0 parent 1:2 taprio num_tc 8 \
map 0 1 2 3 4 5 6 7 \
queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \
base-time 0 sched-entry S 0x7f 990000 sched-entry S 0x80 100000 \
flags 0x0 clockid CLOCK_TAI
This is because tc_modify_qdisc() behaves differently when mqprio is
root, vs when taprio is root.
In the mqprio case, it finds the parent qdisc through
p = qdisc_lookup(dev, TC_H_MAJ(clid)), and then the child qdisc through
q = qdisc_leaf(p, clid). This leaf qdisc q has handle 0, so it is
ignored according to the comment right below ("It may be default qdisc,
ignore it"). As a result, tc_modify_qdisc() goes through the
qdisc_create() code path, and this gives taprio_init() a chance to check
for sch_parent != TC_H_ROOT and error out.
Whereas in the taprio case, the returned q = qdisc_leaf(p, clid) is
different. It is not the default qdisc created for each netdev queue
(both taprio and mqprio call qdisc_create_dflt() and keep them in
a private q->qdiscs[], or priv->qdiscs[], respectively). Instead, taprio
makes qdisc_leaf() return the _root_ qdisc, aka itself.
When taprio does that, tc_modify_qdisc() goes through the qdisc_change()
code path, because the qdisc layer never finds out about the child qdisc
of the root. And through the ->change() ops, taprio has no reason to
check whether its parent is root or not, just through ->init(), which is
not called.
The problem is the taprio_leaf() implementation. Even though code wise,
it does the exact same thing as mqprio_leaf() which it is copied from,
it works with different input data. This is because mqprio does not
attach itself (the root) to each device TX queue, but one of the default
qdiscs from its private array.
In fact, since commit 13511704f8d7 ("net: taprio offload: enforce qdisc
to netdev queue mapping"), taprio does this too, but just for the full
offload case. So if we tried to attach a taprio child to a fully
offloaded taprio root qdisc, it would properly fail too; just not to a
software root taprio.
To fix the problem, stop looking at the Qdisc that's attached to the TX
queue, and instead, always return the default qdiscs that we've
allocated (and to which we privately enqueue and dequeue, in software
scheduling mode).
Since Qdisc_class_ops :: leaf is only called from tc_modify_qdisc(),
the risk of unforeseen side effects introduced by this change is
minimal.

In an incredibly strange API design decision, qdisc->destroy() gets
called even if qdisc->init() never succeeded, not exclusively since
commit 87b60cfacf9f ("net_sched: fix error recovery at qdisc creation"),
but apparently also earlier (in the case of qdisc_create_dflt()).
The taprio qdisc does not fully acknowledge this when it attempts full
offload, because it starts off with q->flags = TAPRIO_FLAGS_INVALID in
taprio_init(), then it replaces q->flags with TCA_TAPRIO_ATTR_FLAGS
parsed from netlink (in taprio_change(), tail called from taprio_init()).
But in taprio_destroy(), we call taprio_disable_offload(), and this
determines what to do based on FULL_OFFLOAD_IS_ENABLED(q->flags).
But looking at the implementation of FULL_OFFLOAD_IS_ENABLED()
(a bitwise check of bit 1 in q->flags), it is invalid to call this macro
on q->flags when it contains TAPRIO_FLAGS_INVALID, because that is set
to U32_MAX, and therefore FULL_OFFLOAD_IS_ENABLED() will return true on
an invalid set of flags.
As a result, it is possible to crash the kernel if user space forces an
error between setting q->flags = TAPRIO_FLAGS_INVALID, and the calling
of taprio_enable_offload(). This is because drivers do not expect the
offload to be disabled when it was never enabled.
The error that we force here is to attach taprio as a non-root qdisc,
but instead as child of an mqprio root qdisc:
$ tc qdisc add dev swp0 root handle 1: \
mqprio num_tc 8 map 0 1 2 3 4 5 6 7 \
