Query Regarding Backporting klp-build from Linux 6.19 to 6.12.x

Hi Josh,

I hope you're doing well.

We're currently using Linux kernel versions 6.12.74 and 6.12.90 in our
environment. We have been using kpatch-build for livepatch generation,
but it doesn't work on these kernels because CONFIG_X86_KERNEL_IBT is
enabled.

Since IBT is an important security feature, disabling
CONFIG_X86_KERNEL_IBT is not an option for us.

While looking for alternatives, I came across the new klp-build
infrastructure that was introduced upstream in Linux 6.19. I also
found your patch series:

https://lists.openwall.net/linux-kernel/2025/06/26/1920

From what I understand, this series introduces the new klp-build
workflow along with the required objtool and livepatch infrastructure.

I wanted to ask whether it would be feasible to backport this entire
patch series to Linux 6.12.74/6.12.90.

Specifically:

Would backporting the complete klp-build patch series be sufficient to
make klp-build functional on a 6.12 kernel?
Are there any additional dependencies or upstream changes outside this
patch series that would also need to be backported?
Have you or anyone else attempted such a backport, or would you expect
significant compatibility issues with the 6.12 stable kernel?
In your opinion, is backporting klp-build to 6.12 a practical
approach, or would you recommend another solution?

Any guidance or recommendations would be greatly appreciated.

Thank you for your time and for all the work you've done on the new
livepatch infrastructure.

Best regards,

Ahamed
