Issue #20642 has been reported by vo.x (Vit Ondruch). ---------------------------------------- Bug #20642: YJIT prevents hardening https://bugs.ruby-lang.org/issues/20642 * Author: vo.x (Vit Ondruch) * Status: Open * ruby -v: ruby 3.3.4 (2024-07-09 revision be1089c8ec) [x86_64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- Working on #20621, it can be seen that annocheck reports: ~~~ Hardened: libruby.so.3.4.0: skip: cf-protection test because mixed Rust and C code - control flow protection is needed but not yet supported by Rust ~~~ To me it is unfair that Ruby users should make a choice between YJIT and hardening. I don't think that Ruby is going to give up YJIT, but maybe Ruby community could put some pressure on Rust? https://github.com/rust-lang/rust/issues/93754 -- https://bugs.ruby-lang.org/
