SMB 1 broken in kernel linux-generic-hwe-22.04 (version 6.2.0-31)

Bug Description

I was running Ubuntu 22.04.3 on kernel version 5.15.0-82-generic, and I installed package linux-generic-hwe-22.04 in order to upgrade to kernel version 6.2.0-31.

That upgrade broke the SMB version 1 protocol. I know that it is an old, deprecated protocol, but I still have to access some legacy systems and devices in a local network.

This breakage has been discussed on the Internet. It is a Linux kernel regression.

This is the commit that fixes it. It is a very small change:

2f6f19c7aaad "cifs: fix regression in very old smb1 mounts"

https://github.com/torvalds/linux/commit/2f6f19c7aaad5005dc75298a413eb0243c5d312d

I am no Linux kernel expert. Could you please backport that fix to the kernel versions that linux-generic-hwe-22.04 installs?

This problem seems fixed now, or at least I am no longer having problems with this Linux Kernel version:

6.2.0-34-generic #34~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Sep 7 13:12:03 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Can somebody else confirm this?

I don't know yet how to check whether that patch mentioned above is included in the latest Ubuntu Kernel version.
