I have a patchset enabling support for both KCFI and IBT in the kernel, but it uses changes not yet landed in stable rustc, which is why I haven't sent it to the list yet: https://github.com/Rust-for-Linux/linux/pull/1034 We've backported the changes to rustc that need to be present onto the Android copy of the compiler, but it will take 6-12 weeks for them to hit stable rustc, which is what general Linux is using. If the IBT part would be helpful by itself immediately, I can split that out - it's only the KCFI portion that won't currently work.
