• Bug#1069301: linux-image-6.1.0-20-amd64: bluetooth causes kernel BUG -

    From Jeremy =?UTF-8?Q?Lain=C3=A9?=@21:1/5 to All on Fri Apr 19 17:40:01 2024
    XPost: linux.debian.kernel

    Package: src:linux
    Version: 6.1.85-1
    Severity: important
    X-Debbugs-Cc: jeremy.laine@m4x.org

    Dear Maintainer,

    After upgrading from linux-image-6.1.0-18-amd64 to
    linux-image-6.1.0-20-amd64, bluetooth no longer works and a kernel BUG is visible in dmesg hinting at a memory safety issue.

    It is not necessary to attempt to connect to any specific bluetooth
    device to trigger the problem, the problem arises as soon as the system
    boots.

    I cannot reproduce the problem when booting back into the previous kernel image.

    Dear Maintainer,

    After upgrading from linux-image-6.1.0-18-amd64 to linux-image-6.1.0-20-amd64, bluetooth no longer works and a kernel BUG is visible in dmesg hinting at a memory safety issue.

    It is not necessary to attempt to connect to any specific bluetooth
    device to trigger the problem, the problem arises as soon as the system boots.

    I cannot reproduce the problem when booting back into the previous kernel image.

    Would it be possible to do some experiments/debugging:

    - Can you reproduce the issue with 6.1.85 upstream itself?

    - If so can you try the current 6.1.87 (as of time of writing), does
    the issue reproduce there?

    - If it's still happening, can you try to bisect the changes between
    6.1.76 and 6.1.85 to identify the culprit?

    Regards,
    Salvatore

    Hi Salvatore,

    It had been a while (like 10+ years) since I built a kernel from source, so this guide was very welcome, and the "make bindeb-pkg" target is great:

    https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s-kernel-org-package

    It looks like the problem is present in the upstream kernel, I have so far reproduced it with:

    - linux 6.1.85
    - linux 6.1.87

    I'll start building previous patch releases until I find one that works,
    but it's slow going!

    Cheers,
    Jeremy

    Hi Salvatore,

    I've finished bisecting and the version that seems to introduce the
    breakage is 6.1.83.

    I tested the following upstream kernels:

    - linux 6.1.80 => OK
    - linux 6.1.82 => OK
    - linux 6.1.83 => BUG
    - linux 6.1.85 => BUG
    - linux 6.1.87 => BUG

    I looks like 6.1.83 introduced quite a few bluetooth changes, so I don't
    know which one caused the breakage:

    https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.83

    What else can I do to assist?

    Cheers,
    Jeremy

    Over the weekend I reported the issue to the linux-bluetooth mailing
    list, which led to bisecting the issue down to a single commit:

    https://lore.kernel.org/linux-bluetooth/CADRbXaDqx6S+7tzdDPPEpRu9eDLrHQkqoWTTGfKJSRxY=hT5MQ@mail.gmail.com/

    Hi,

    Seeing exactly the same bug with an Broadcom Corp. BCM2045B (BDC-2.1)
    bluetooth device, so its not just the Intel AX211.

    Jeremy, thanks for tracking this down!
