Offloading police with action TC_ACT_UNSPEC was erroneously disabled even
though it was supported by mlx5 matchall offload implementation, which
didn't verify the action type but instead assumed that any single police
action attached to matchall classifier is a 'continue' action. Lack of
action type check made it non-obvious what mlx5 matchall implementation
actually supports and caused implementers and reviewers of referenced
commits to disallow it as a part of improved validation code.

All callers of taprio_offload_get() and taprio_offload_free() prior to
the blamed commit are conditionally compiled based on CONFIG_NET_SCH_TAPRIO.
felix_vsc9959.c is different; it provides vsc9959_qos_port_tas_set()
even when taprio is compiled out.
Provide shim definitions for the functions exported by taprio so that
felix_vsc9959.c is able to compile. vsc9959_qos_port_tas_set() in that
case is dead code anyway, and ocelot_port->taprio remains NULL, which is
fine for the rest of the logic.

This adds a tracepoint event for 9p fid lifecycle tracing: when a fid
is created, its reference count increased/decreased, and freed.
The new 9p_fid_ref tracepoint should help anyone wishing to debug any
fid problem such as missing clunk (destroy) or use-after-free.

I was recently reminded that it is not clear that p9_client_clunk()
was actually just decrementing refcount and clunking only when that
reaches zero: make it clear through a set of helpers.
This will also allow instrumenting refcounting better for debugging

Increase akm_suites array size in struct cfg80211_crypto_settings to 10
and advertise the capability to userspace. This allows userspace to send
more than two AKMs to driver in netlink commands such as
NL80211_CMD_CONNECT.
This capability is needed for implementing WPA3-Personal transition mode
correctly with any driver that handles roaming internally. Currently,
the possible AKMs for multi-AKM connect can include PSK, PSK-SHA-256,
SAE, FT-PSK and FT-SAE. Since the count is already 5, increasing
the akm_suites array size to 10 should be reasonable for future
usecases.

The virtual time scheduler code has a number of issues:
- queues slowed down by hardware/firmware powersave handling were not properly
handled.
- on ath10k in push-pull mode, tx queues that the driver tries to pull from
were starved, causing excessive latency
- delay between tx enqueue and reported airtime use were causing excessively
bursty tx behavior
The bursty behavior may also be present on the round-robin scheduler, but there
it is much easier to fix without introducing additional regressions

br_switchdev_fdb_notify() creates an on-stack FDB info variable, and
initializes it member by member. As such, newly added fields which are
not initialized by br_switchdev_fdb_notify() will contain junk bytes
from the stack.
Other uses of struct switchdev_notifier_fdb_info have a struct
initializer which should put zeroes in the uninitialized fields.
Add a reminder above the structure for future developers. Recently
discussed during review.

When verdict is NF_STOLEN, the skb might have been freed.
When tracing is enabled, this can result in a use-after-free:
1. access to skb->nf_trace
2. access to skb->mark
3. computation of trace id
4. dump of packet payload
To avoid 1, keep a cached copy of skb->nf_trace in the
trace state struct.
Refresh this copy whenever verdict is != STOLEN.
Avoid 2 by skipping skb->mark access if verdict is STOLEN.
3 is avoided by precomputing the trace id.
Only dump the packet when verdict is not "STOLEN".

Currently, bond_opt_value are mostly used for bonding option settings. If
we want to set a value for slave, we need to re-alloc a string to store
both slave name and vlaue, like bond_option_queue_id_set() does, which
is complex and dumb.
As Jon suggested, let's add a union field slave_dev for bond_opt_value,
which will be benefit for future slave option setting. In function
__bond_opt_init(), we will always check the extra field and set it
if it's not NULL.

Commit 8a59f9d1e3d4 ("sock: Introduce sk->sk_prot->psock_update_sk_prot()")
has moved the inet_csk_has_ulp(sk) check from sk_psock_init() to
the new tcp_bpf_update_proto() function. I'm guessing that this
was done to allow creating psocks for non-inet sockets.
Unfortunately the destruction path for psock includes the ULP
unwind, so we need to fail the sk_psock_init() itself.
Otherwise if ULP is already present we'll notice that later,
and call tcp_update_ulp() with the sk_proto of the ULP
itself, which will most likely result in the ULP looping
its callbacks.

unix_table_locks are to protect the global hash table, unix_socket_table.
The previous commit removed it, so let's clean up the unnecessary locks.
Here is a test result on EC2 c5.9xlarge where 10 processes run concurrently
in different netns and bind 100,000 sockets for each.
without this series : 1m 38s
with this series : 11s
It is ~10x faster because the global hash table is split into 10 netns in
this case.

This commit adds a per netns hash table for AF_UNIX, which size is fixed
as UNIX_HASH_SIZE for now.
The first implementation defines a per-netns hash table as a single array
of lock and list:
struct unix_hashbucket {
spinlock_t lock;
struct hlist_head head;
};
struct netns_unix {
struct unix_hashbucket *hash;
...
};
But, Eric pointed out memory cost that the structure has holes because of
sizeof(spinlock_t), which is 4 (or more if LOCKDEP is enabled). [0] It
could be expensive on a host with thousands of netns and few AF_UNIX
sockets. For this reason, a per-netns hash table uses two dense arrays.
struct unix_table {
spinlock_t *locks;
struct hlist_head *buckets;
};
struct netns_unix {
struct unix_table table;
...
};
Note the length of the list has a significant impact rather than lock
contention, so having shared locks can be an option. But, per-netns
locks and lists still perform better than the global locks and per-netns
lists. [1]
Also, this patch adds a change so that struct netns_unix disappears from
struct net if CONFIG_UNIX is disabled.

Currently, the size of AF_UNIX hash table is UNIX_HASH_SIZE * 2,
the first half for bind()ed sockets and the second half for unbound
ones. UNIX_HASH_SIZE * 2 is used to define the table and iterate
over it.
In some places, we use ARRAY_SIZE(unix_socket_table) instead of
UNIX_HASH_SIZE * 2. However, we cannot use it anymore because we
will allocate the hash table dynamically. Then, we would have to
add UNIX_HASH_SIZE * 2 in many places, which would be troublesome.
This patch adapts the UNIX_HASH_SIZE definition to include bound
and unbound sockets and defines a new UNIX_HASH_MOD macro to ease
calculations.

The MLO links used for connection with an MLD AP are decided by the
driver in case of SME offloaded to driver.
Add support for the drivers to indicate the information of links used
for MLO connection in connect and roam callbacks, update the connected
links information in wdev from connect/roam result sent by driver.
Also, send the connected links information to userspace.
Add a netlink flag attribute to indicate that userspace supports
handling of MLO connection. Drivers must not do MLO connection when this
flag is not set. This is to maintain backwards compatibility with older
supplicant versions which doesn't have support for MLO connection.

Add some optional callbacks for link add/remove so that
drivers can react here. Initially, I thought it would be
sufficient to just create the link in start_ap etc., but
it turns out that's not so simple, since there are quite
a few callbacks that can be called: if they're erroneously
without start_ap, things might crash.
Thus it might be easier for drivers to allocate all the
necessary data structures immediately, to not have to
worry about it in each callback, since cfg80211 checks
that the link ID is valid (has been added.)

Add the necessary infrastructure, including a new driver
method, to add/remove links to/from a station. To do this,
refactor the link alloc/free a bit, splitting that so we
can do it without linking them, to handle failures better.
Note that a station entry must be created representing an
MLD or a non-MLD STA, it cannot change between the two.
When representing an MLD, the 'deflink' is used for the
first link, which might be removed later, in which case
the memory isn't reused.

If the interface is an MLD, then we don't know which band
the frame will be transmitted on, and we don't know how to
look up the band. Set the band information to zero in that
case, the driver cannot rely on it anyway.

bigger now.

Add the necessary infrastructure, including a new driver
method, to add/remove links to/from an interface.
Also add the missing link address to bss_conf (which we
use as link_conf too), and fill it, in station mode for
now just randomly, in AP mode we get the address from
cfg80211 since the link must be created with an address
first.

For authentication, we need the BSS, the link_id and the AP
MLD address to create the link and station, (for now) the
driver assigns a link address and sends the frame, the MLD
address needs to be the address of the interface.
For association, pass the list of BSSes that were selected
for the MLO connection, along with extra per-STA profile
elements, the AP MLD address and the link ID on which the
association request should be sent.
Note that for now we don't have a proper way to pass the link
address(es) and so the driver/mac80211 will select one, but
depending on how that selection works it means that assoc w/o
auth data still being around (mac80211 implementation detail)
the association won't necessarily work - so this will need to
be extended in the future to sort out the link addressing.

Start making some SMPS related code MLD-aware. This isn't
really done yet, but again cuts down our 'deflink' reliance.

Update the code in vht.c and add the link_id parameter where
necessary.

Remove MAX_STA_LINKS and use IEEE80211_MLD_MAX_NUM_LINKS
instead to unify between the station and other data structures.

Make the channel context code MLO aware, along with some
functions that it uses, so that the chan.c file is now
MLD-clean and no longer uses deflink/bss_conf/etc.

Add pointers so we can start using link_id throughout the
code, even if for now only link ID 0 is valid, pointing
to the "built-in" bss_conf, which is used by drivers that
are not aware of MLD.

Split the bss_info_changed method to vif_cfg_changed and
link_info_changed, with the latter getting a link ID.
Also change the 'changed' parameter to u64 already, we
know we need that.
