first, it disables the interrupt generation, then it waits for the

handler or tasklet re-enables the interrupt generation. And we fall in a

The easiest way to reproduce this warning is to run scan with dualband
NIC in noisy environments, when the channel 11 runs multiple APs. In my
tests if the APs num >= 12, the warning appears in the first few
seconds of scanning.
In order to fix this, the Rx disable code moved to a higher level and
placed before the channel pointer update. This is also makes the code a
bit more symmetrical, since we disable and enable the Rx in the same
function.
In fact, at the pointer update time new frames should not appear,
because interrupt generation at this point should already be disabled.
The next patch should address this issue.

Commit
c0c09bfdc415 ("rhashtable: avoid unnecessary wakeup for worker

Instead of leaving the current shift in the core rhashtable structure,
it can be cached inside the individual bucket tables.
There, it will only be initialized once during a new table allocation
in the shrink/expansion slow path, and from then onward it stays immutable
for the rest of the bucket table liftime.
That allows shift to be non-atomic. The patch also moves hash_rnd

cls_bpf: do eBPF invocation under non-bh RCU lock variant for maps
Currently, it is possible in cls_bpf to access eBPF maps only under
rcu_read_lock_bh() variants: while on ingress side, that is, handle_ing(),
the classifier would be called from __netif_receive_skb_core() under
rcu_read_lock(); on egress side, however, it's rcu_read_lock_bh() via
__dev_queue_xmit().
This rcu/rcu_bh mix doesn't work together with eBPF maps as they require
soley to be called under rcu_read_lock(). eBPF maps could also be shared
among various other eBPF programs (possibly even with other eBPF program
types, f.e. tracing) and user space processes, so any context is assumed.
Therefore, a possible fix for cls_bpf is to wrap/nest eBPF program

fib_trie: Provide a deterministic order for fib_alias w/ tables merged
This change makes it so that we should always have a deterministic ordering
for the main and local aliases within the merged table when two leaves
overlap.
So for example if we have a leaf with a key of 192.168.254.0. If we
previously added two aliases with a prefix length of 24 from both local and
main the first entry would be first and the second would be second. When I
was coding this I had added a WARN_ON should such a situation occur as I
wasn't sure how likely it would be. However this WARN_ON has been
triggered so this is something that should be addressed.
With this patch the ordering of the aliases is as follows. First they are
sorted on prefix length, then on their table ID, then tos, and finally
priority. This way what we end up doing is essentially interleaving the
two tables on what used to be leaf_info structure boundaries.

ebpf: verifier: check that call reg with ARG_ANYTHING is initialized
I noticed that a helper function with argument type ARG_ANYTHING does

This can worst case lead to unintented stack memory leakage in future
helper functions if they are not carefully designed, or unintended
application behaviour in case the application developer was not careful
enough to match a correct helper function signature in the API.
The underlying issue is that ARG_ANYTHING should actually be split
into two different semantics:
1) ARG_DONTCARE for function arguments that the helper function
does not care about (in other words: the default for unused
function arguments), and
2) ARG_ANYTHING that is an argument actually being used by a
helper function and *guaranteed* to be an initialized register.
The current risk is low: ARG_ANYTHING is only used for the 'flags'
argument (r4) in bpf_map_update_elem() that internally does strict
checking.

of available stations in the driver, so don't warn on it.

iwlwifi: trans: Take ownership on secure machine before FW load
When we load the firmware for the 8000 B step device, it'll
verify its signature. In the current version of the
hardware, there can be a race between the WiFi firmware
being loaded and the Bluetooth firmware being loaded.
Check that WiFi is authenticated, if not, take ownership
on the authentication machine to make sure that the WiFi
firmware will be authenticated.

iwlwifi: mvm: reflect TDLS pm state in mvmvif->pm_enabled
When entering D0i3, the MVM mutex cannot be grabbed. This interferes
with the calculation of the number of connected TDLS stations during
the setup of the power cmd.
The goal is to disable power saving for all vifs while any TDLS station
is connected. For this purpose it is enough to keep the pm_enabled
member of all mvmvifs as false. An update of the power state already
occurs when a TDLS station is added/removed, so the values are correctly
updated.

iwlwifi: pcie: speed up the Tx DMA stop flow
We don't need to acquire MAC access for each access, it
makes much more sense to keep the MAC access. This speeds
up the Tx DMA stop flow significantly.
Moreover, if one channel can't be stopped, stop the others
but don't poll for them to avoid being stuck there for a
long time.
This solves a situation in which we were stuck in that flow
for way too long with a spinlock held which led to a kernel
panic.
