Package: linux-image-6.1.0-10-amd64
Severity: important
Tags: patch

Dear Maintainer,

Current kernel failed to load modules for MASQUERADE nat rules giving the following
in dmesg:

[37404.063872] BPF: [99720] ENUM STROY 
[37404.064350] BPF: size=4 vlen=14
[37404.064699] BPF:  
[37404.065000] BPF: Invalid name
[37404.065287] BPF: 
[37404.065463] failed to validate module [nf_conntrack] BTF: -22
[37404.067137] missing module BTF, cannot register kfuncs

The following upstream patch fixes the issue:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=3de4d22cc9ac7c9f38e10edcf54f9a8891a9c2aa

And it has been included in upstream stable 6.1 kernel releases since 6.1.39:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-6.1.y&ofs=400

Please include in Bookworm as its currently preventing netavark from using iptables
to load the MASQUERADE module and, thus, preventing me from running containers.

Thanks. :)

PS: This, I think, is covered in bug 1003965 but my attempt to email into that bug appears
to have failed. If it ever succeeds apologies for the dupe report. :(
