5e769878ad mac80211: CVE-2024-46760: rtw88: schedule rx work after everything is set up
link: https://lore.kernel.org/all/2024091842-CVE-2024-46760-1eb3@gregkh
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.

Affected and fixed versions
===========================

	Fixed in 6.6.51 with commit c83d464b82a8
	Fixed in 6.10.10 with commit 25eaef533bf3
	Fixed in 6.11 with commit adc539784c98

Please see https://www.kernel.org for a full list of currently supported
kernel versions by the kernel community.

Unaffected versions might change over time as fixes are backported to
older supported kernel versions.  The official CVE entry at
	https://cve.org/CVERecord/?id=CVE-2024-46760
will be updated if fixes are backported, please check that for the most
up to date information about this issue.

Affected files
==============

The file(s) affected by this issue are:
	drivers/net/wireless/realtek/rtw88/usb.c

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:
	https://git.kernel.org/stable/c/c83d464b82a8ad62ec9077637f75d73fe955635a

bce7b4f8e5 mac80211: carl9170: re-fix fortified-memset warning
The carl9170_tx_release() function sometimes triggers a fortified-memset
warning in my randconfig builds:

In file included from include/linux/string.h:254,
                 from drivers/net/wireless/ath/carl9170/tx.c:40:

  493 |                         __write_overflow_field(p_size_field, size);

Kees previously tried to avoid this by using memset_after(), but it seems
this does not fully address the problem. I noticed that the memset_after()
here is done on a different part of the union (status) than the original
cast was from (rate_driver_data), which may confuse the compiler.

Unfortunately, the memset_after() trick does not work on driver_rates[]
because that is part of an anonymous struct, and I could not get
struct_group() to do this either. Using two separate memset() calls
on the two members does address the warning though.

512b762ddb mac80211: brcm: disable dump_survey on Raspberry Pi
Enabling this causes slow iwinfo calls on Raspberry Pi and LuCI slows down
when wireless is enabled.

1278d47bea mac80211: avoid crashing on invalid band info
Frequent crashes have been observed on MT7916 based platforms. While the
root of these crashes are currently unknown, they happen when decoding
rate information of connected STAs in AP mode. The rate-information is
associated with a band which is not available on the PHY.

Check for this condition in order to avoid crashing the whole system.
This patch should be removed once the roout cause has been found and
fixed.

438a97fab6 mac80211: fix a race condition related to enabling fast-xmit
fast-xmit must only be enabled after the sta has been uploaded to the driver,
otherwise it could end up passing the not-yet-uploaded sta via drv_tx calls
to the driver, leading to potential crashes because of uninitialized drv_priv
data.
Add a missing sta->uploaded check and re-check fast xmit after inserting a sta.

3e738781a9 mac80211: fix flush during station removal
This fixes WARN_ONs when using AP_VLANs after station removal. The flush
call passed AP_VLAN vif to driver, but because these vifs are virtual and
not registered with drivers, we need to translate to the correct AP vif
first.

6bcd1c2501 mac80211: sync some rt2x00 patches with wireless-next
Some local patches have been sent to upstream and they are slightly
different from the upstream version. So it's better to replace them
to avoid conflicts with the new mac80211 backport driver. The
different parts have been merged into patch 996.

This commit also includes some additional fixes:
* Fix watchdog function.
* Improve MT7620 register initialization.
* Introduce DMA busy watchdog for rt2800.

P.S.
Sometimes rt2800 series chips may fall into a DMA busy state. The
tx queues become very slow and the client cannot connect to the AP.
Usually, We can see a lot of hostapd warnings at this point:
'hostapd: IEEE 802.11: did not acknowledge authentication response'

The DMA busy watchdog can help the driver automatically recover
from this abnormal state. By the way, setting higer 'cell_density'
and disabling 'disassoc_low_ack' can significantly reduce the
probability of the DMA busy.

a5ba28454b mac80211: ath9k-htc: support "chanbw" in debugfs
ath9k-htc USB-based adapters also support 5/10MHz channel bandwidth.
Move the code handling the features in debugfs to common-debug.c,
and create proper registration functions to use in debug.c and
htc_drv_debug.c, leaving only debugfs registration there.

While at that, refresh one patch that would conflict otherwise.

Tested on TP-Link Archer C7v2 (ath79) and TP-Link WN722Nv1 (AR9287)
and WN822Nv2 (AR7010+AR9287).
