d73f8fb1d9 wifi: iwlwifi: debug: set CDB indication from CSR
In order to set the CDB indication in the dump meta data, we read it from
a specific prph register.
There is a known issue with that register in Xnj setups - in that case it
will always indicate CDB.
Instead of detecting the jacket case and then hardcode whether the CDB
indication should or shouldn't be set (according the CRF),
we can retrieve the CDB bit from the hw_rf_id (CSR_HW_RF_ID).
There is also no reason to do it conditionally only for ax210 / BnJ.
Cleanup the code a bit.

befaea3040 wifi: iwlwifi: mld: don't check the TPT counters when scanning
If there is an ongoing scan that lasts long, the MPDU counters may not
increase enough due the device being busy with scanning and not
because we are in a low throughput scenario.

In that case we don't want to block EMLSR.
Instead, stop checking the counters from the moment we started
scanning, and when the scan ends - clear the counters and schedule a
check in 5 seconds, as usual.

Note that this is only done for regular scan since MLO scan is too short
to affect the counters, and scheduled scan is mainly used when we are
not connected.

Also note that we only stop checking whether to block EMLSR, and not if to
unblock.

complexity is much lower without that.

For different MACs we maintain the configs in different

worthwhile trade-off for maintenance and simplicity. So
allow different MAC types to have the same config. This
could allow the same config for two MACs in the same MAC
family, but that's not hugely important. Also simplify
the test to not build a config list, there's no good
reason to do that.

8f7561209e wifi: iwlfiwi: mvm: Fix the rate reporting
The rate validation in mac80211 considers a rate to be valid iff both
the rate index and the count are positive. When the rate scaling is
managed in the driver and not enough traffic passed to set the actual
rate, the driver set the rate to be the optimal rate. However, the rate
count is not set and thus the rate is considered not valid. Fix it by
setting the count to 1.

Simplify the logic here by tracking only suspended as a
status bit, and remove CMD_SEND_IN_D3 completely. There
is no value, since the op-mode sets the state and also
sends the commands.

Accidentally spotted while trying to understand what else needs

are adjacent to dev_set_allmulti or dev_disable_lro so it should
be safe to add the lock. Note that new netif_set_promiscuity is
currently unused, the locked paths call __dev_set_promiscuity directly.

35076d2223 erofs: ensure the extra temporary copy is valid for shortened bvecs
When compressed data deduplication is enabled, multiple logical extents
may reference the same compressed physical cluster.

The previous commit 94c43de735 ("erofs: fix wrong primary bvec
selection on deduplicated extents") already avoids using shortened
bvecs.  However, in such cases, the extra temporary buffers also
need to be preserved for later use in z_erofs_fill_other_copies() to
to prevent data corruption.

IOWs, extra temporary buffers have to be retained not only due to
varying start relative offsets (`pageofs_out`, as indicated by
`pcl->multibases`) but also because of shortened bvecs.

android.hardware.graphics.composer@2.1.so : 270696 bytes
   0:        0..  204185 |  204185 :  628019200.. 628084736 |   65536
-> 1:   204185..  225536 |   21351 :  544063488.. 544129024 |   65536
   2:   225536..  270696 |   45160 :          0..         0 |       0

com.android.vndk.v28.apex : 93814897 bytes
...
   364: 53869896..54095257 |  225361 :  543997952.. 544063488 |   65536
-> 365: 54095257..54309344 |  214087 :  544063488.. 544129024 |   65536
   366: 54309344..54514557 |  205213 :  544129024.. 544194560 |   65536
...

Both 204185 and 54095257 have the same start relative offset of 3481,
but the logical page 55 of `android.hardware.graphics.composer@2.1.so`
ranges from 225280 to 229632, forming a shortened bvec [225280, 225536)
that cannot be used for decompressing the range from 54095257 to
54309344 of `com.android.vndk.v28.apex`.

Since `pcl->multibases` is already meaningless, just mark `be->keepxcpy`
on demand for simplicity.

Again, this issue can only lead to data corruption if `-Ededupe` is on.

08e9f2d584 net: Lock netdevices during dev_shutdown
__qdisc_destroy() calls into various qdiscs .destroy() op, which in turn
can call .ndo_setup_tc(), which requires the netdev instance lock.

This commit extends the critical section in
unregister_netdevice_many_notify() to cover dev_shutdown() (and
dev_tcx_uninstall() as a side-effect) and acquires the netdev instance
lock in __dev_change_net_namespace() for the other dev_shutdown() call.

This should now guarantee that for all qdisc ops, the netdev instance
lock is held during .ndo_setup_tc().

0093cb194a ice: use DSN instead of PCI BDF for ice_adapter index
Use Device Serial Number instead of PCI bus/device/function for
the index of struct ice_adapter.

Functions on the same physical device should point to the very same
ice_adapter instance, but with two PFs, when at least one of them is
PCI-e passed-through to a VM, it is no longer the case - PFs will get
seemingly random PCI BDF values, and thus indices, what finally leds to
each of them being on their own instance of ice_adapter. That causes them
to don't attempt any synchronization of the PTP HW clock usage, or any
other future resources.

DSN works nicely in place of the index, as it is "immutable" in terms of
virtualization.
