After a chat with @teburd @edersondisouza @selescop at ZDS24, wishlist in no particular order:

unified architecture relocation
unified linking path
kobject instantiation from the llext
XIP
security signing
versioning / ABI for syscalls
versioning for exported symbols, maybe subsys level?
module information / init / done function
ask for capabilities -> get assigned permissions
limit extension to userspace
filter syscalls
inter-extension symbol linking

Hi @pillo79! We appreciate you submitting your first issue for our open-source project. 🌟

Even though I'm a bot, I can assure you that the whole community is genuinely grateful for your time and effort. 🤖💙

After a discussion at EOSS, XIP could be implemented by providing a function that applies all relocations assuming given target addresses for storing the ELF sections. Not necessarily where those elf sections are in memory at the time of manipulation. I thought this was an incredible idea and I’m hopeful someone will contribute it.
