ASO operations are global to whole IPsec as they share one DMA address
for all operations. As such all WQE operations need to be protected with
lock. In this case, it must be spinlock to allow mlx5e_ipsec_aso_query()
operate in atomic context.

aso->use_cache variable introduced in commit 8c582ddfbb47 ("net/mlx5e: Handle
hardware IPsec limits events") was an optimization to skip recurrent calls
to mlx5e_ipsec_aso_query(). Such calls are possible when lifetime event is
generated:
-> mlx5e_ipsec_handle_event()
-> mlx5e_ipsec_aso_query() - first call
-> xfrm_state_check_expire()
-> mlx5e_xfrm_update_curlft()
-> mlx5e_ipsec_aso_query() - second call
However, such optimization not really effective as mlx5e_ipsec_aso_query()
is needed to be called for update ESN anyway, which was missed due to misplaced
use_cache assignment.

Currently decap action is set based on tunnel_id. That means it is
set unconditionally. But for decap, ct and sample actions, decap is
done before ct. No need to decap again in sample.
And the actions are set correctly when parsing. So set decap action
based on attr instead of tunnel_id.

MODIFY_SCHEDULING_ELEMENT
According to HW spec parent_element_id field should be reserved (0x0) when calling
MODIFY_SCHEDULING_ELEMENT command.
This patch remove the wrong initialization of reserved field, parent_element_id, on
mlx5_qos_update_node.

This validation function is relevant only for XSK cases, hence it
assumes to be called only with xsk != NULL.
Thus checking for invalid xsk pointer is redundant and misleads static
code analyzers.
This commit removes redundant xsk pointer check.
This solves the following smatch warning:
drivers/net/ethernet/mellanox/mlx5/core/en/params.c:481
mlx5e_mpwrq_validate_xsk() error: we previously assumed 'xsk' could be
null (see line 478)

The cited commit changed class of tc_ht internal mutex in order to avoid
false lock dependency with fs_core node and flow_table hash table
structures. However, hash table implementation internally also includes a
workqueue task with its own lockdep map which causes similar bogus lockdep
splat[0]. Fix it by also adding dedicated class for hash table workqueue
work structure of tc_ht.

====================
net: mdio: Continue separating C22 and C45
I've picked this older series from Andrew up and rebased it onto
the latest net-next.
This is the third (and hopefully last) patch set in the series which
separates the C22 and C45 MDIO bus transactions at the API level to the
MDIO bus drivers.
The first patch is a newer version of the former "net: dsa: Separate C22
and C45 MDIO bus transaction methods", which only contains the mt7530
changes. Although posted as v1, because this is a new series, there
is a changelog included in the patch comment section.
The last patch is a new one, which isn't from Andrew's tree.

The IPA interrupt can fire when pm_runtime is disabled due to it racing
with the PM suspend/resume code. This causes a splat in the interrupt
handler when it tries to call pm_runtime_get().
Explicitly disable the interrupt in our ->suspend callback, and
re-enable it in ->resume to avoid this. If there is an interrupt pending
it will be handled after resuming. The interrupt is a wake_irq, as a
result even when disabled if it fires it will cause the system to wake
from suspend as well as cancel any suspend transition that may be in
progress. If there is an interrupt pending, the ipa_isr_thread handler
will be called after resuming.

syzbot reports a possible deadlock in rfcomm_sk_state_change [1].
While rfcomm_sock_connect acquires the sk lock and waits for
the rfcomm lock, rfcomm_sock_release could have the rfcomm
lock and hit a deadlock for acquiring the sk lock.
Here's a simplified flow:
rfcomm_sock_connect:
lock_sock(sk)
rfcomm_dlc_open:
rfcomm_lock()
rfcomm_sock_release:
rfcomm_sock_shutdown:
rfcomm_lock()
__rfcomm_dlc_close:
rfcomm_k_state_change:
lock_sock(sk)
This patch drops the sk lock before calling rfcomm_dlc_open to
avoid the possible deadlock and holds sk's reference count to
prevent use-after-free after rfcomm_dlc_open completes.

When a connection is re-used, following can happen:
[ connection starts to close, fin sent in either direction ]
> syn # initator quickly reuses connection
< ack # peer sends a challenge ack
> rst # rst, sequence number == ack_seq of previous challenge ack
> syn # this syn is expected to pass
Problem is that the rst will fail window validation, so it gets
tagged as invalid.
If ruleset drops such packets, we get repeated syn-retransmits until
initator gives up or peer starts responding with syn/ack.
Before the commit indicated in the "Fixes" tag below this used to work:
The challenge-ack made conntrack re-init state based on the challenge
ack itself, so the following rst would pass window validation.
Add challenge-ack support: If we get ack for syn, record the ack_seq,
and then check if the rst sequence number matches the last ack number
seen in reverse direction.

That just rebuilds kvm-stat.c on x86, no change in functionality.

GCC 11.1.0 and 11.2.0 generate a wrong warning when compiling the
kernel e.g. with allmodconfig:
arch/s390/kernel/setup.c: In function ‘setup_lowcore_dat_on’:
./include/linux/fortify-string.h:57:33: error: ‘__builtin_memcpy’ reading 128 bytes from a region of size 0 [-Werror=stringop-overread]
...
arch/s390/kernel/setup.c:526:9: note: in expansion of macro ‘memcpy’
526 | memcpy(abs_lc->cregs_save_area, S390_lowcore.cregs_save_area,
| ^~~~~~
This could be addressed by using absolute_pointer() with the
S390_lowcore macro, but this is not a good idea since this generates
worse code for performance critical paths.
Therefore simply use a for loop to copy the array in question and get
rid of the warning.

In a number of cases the driver assigns a default value of -1 to
priv->plat->phy_addr. This may result in calling mdiobus_get_phy()
with addr parameter being -1. Therefore check for this scenario and
bail out before calling mdiobus_get_phy().

Add a check for empty report_list in bigben_probe().
The missing check causes a type confusion when issuing a list_entry()
on an empty report_list.
The problem is caused by the assumption that the device must
have valid report_list. While this will be true for all normal HID
devices, a suitably malicious device can violate the assumption.

The caller may pass any value as addr, what may result in an out-of-bounds
access to array mdio_map. One existing case is stmmac_init_phy() that
may pass -1 as addr. Therefore validate addr before using it.
