Description
===========
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: usb: schedule rx work after everything is set up
Right now it's possible to hit NULL pointer dereference in
rtw_rx_fill_rx_status on hw object and/or its fields because
initialization routine can start getting USB replies before
rtw_dev is fully setup.
The stack trace looks like this:
rtw_rx_fill_rx_status
rtw8821c_query_rx_desc
rtw_usb_rx_handler
...
queue_work
rtw_usb_read_port_complete
...
usb_submit_urb
rtw_usb_rx_resubmit
rtw_usb_init_rx
rtw_usb_probe
So while we do the async stuff rtw_usb_probe continues and calls
rtw_register_hw, which does all kinds of initialization (e.g.
via ieee80211_register_hw) that rtw_rx_fill_rx_status relies on.
Fix this by moving the first usb_submit_urb after everything
is set up.
For me, this bug manifested as:
[ 8.893177] rtw_8821cu 1-1:1.2: band wrong, packet dropped
[ 8.910904] rtw_8821cu 1-1:1.2: hw->conf.chandef.chan NULL in rtw_rx_fill_rx_status
because I'm using Larry's backport of rtw88 driver with the NULL
checks in rtw_rx_fill_rx_status.
The Linux kernel CVE team has assigned CVE-2024-46760 to this issue.

Mitigation
==========
The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes. Individual
changes are never tested alone, but rather are part of a larger kernel
release. Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all. If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:

Brings lots of driver updates and API changes needed for mt76 updates.
Disable iwlwifi and ath11k on 5.15, since backport is too difficult,
and the only remaining targets won't need those drivers.

of_get_mac_address() was backported in our OpenWrt kernel, remove the
change from backports.

This backports version 5.11.22 and later does not support kernel
versions < 4.4, this allows us to remove some patches too.

The removed patches were integrated upstream.
The brcmf_driver_work workqueue was removed in brcmfmac with kernel
5.10.42, the asynchronous call was covered to a synchronous call. There
is no need to wait any more.
This part was removed manually from this patch:
brcm/860-brcmfmac-register-wiphy-s-during-module_init.patch
