Hi,
I'm on Ubuntu 20.04 with kernel version 5.11 and I keep hitting the
"Module has invalid ELF structures" error on a kernel module I'm
building. I know this is related to the "harden ELF info handling"
patch that was introduced. Are there any useful ways to debug this? Is
there anything I should be mindful of when building the kernel module
to avoid this?
Best,
Eliyam

Look for the already merged patch, "module: change to print useful
messages from elf_validity_check()".
$ git describe --contains 7fd982f394c42f25a73fe9dfbf1e6b11fa26b40a
v5.16-rc1~95^2
