Package: src:linux
Version: 5.15.5-1
Severity: normal
Tags: upstream

After booting the system and inserting the wireless USB dongle, a NULL pointer dereference in the kernel is printed immediately to the TTY (see below). Consequences:

- The wireless interface that I expected is not added (wlan0).
- `systemctl reboot` gets stuck.

The device in question is:

 - 13b1:0039       http://linux-hardware.org/?id=usb:13b1-0039 (on insert)
 - 13b1:0bdc       http://linux-hardware.org/?id=usb:13b1-0bdc (on boot)

(The device is a "morphing device", it has a different ID on boot than it does on insertion. But that's neither here nor there for this specific bug.)

This bug does *not* occur on kernel 5.14.16-1 (with the same packages installed, just selecting the older kernel from the grub menu.

I did the following to narrow down the potential commits that could cause this:

    $ git log --oneline v5.14.16..v5.15.5 drivers/net/wireless/broadcom
    e5be2a62567f b43: fix a lower bounds test

    c2dac3d2d3f1 brcmfmac: firmware: Fix firmware loading
    5ff013914c62 brcmfmac: firmware: Allow per-board firmware binaries

Of those, 5ff013914c62 by Linus Walleij is the first the one that introduces the
brcm_alt_fw_path function. I'm guessing that's the culprit. I don't have a
handy setup to do bisections right now, but I hope that if Linus sees this the
cause might become obvious.

Suggested forward CC's for upstream who were involved in the process of creating/reviewing this code: linus.walleij@linaro.org,kvalo@codeaurora.org,aspriel@gmail.com.

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
