Re: [Xen-devel] livepatch-build-tools: fix section mismatch



HI all

A quick bump on this, and added Andrew to the CC list since he appears to have looked at livepatch 'stuff' recently.

Was this patch of any interest at all? Or just wrong? After reading patch submission guidlines, should I resend this a different way?

Regards, Glenn

I hit an issue generating a livepatch for a recent xsa. I saw the following lines from the create-diff-object.log ...

/livepatch-build-tools/create-diff-object: ERROR: grant_table.o: kpatch_regenerate_special_section: 1162: group size mismatch for section .altinstructions

This looks really similar to the issue reported and fixed in https://github.com/dynup/kpatch/pull/528

The attached patch is based on that report, and resulted in a good livepatch. The alt section size in my case was actually 14.

Regards, Glenn
