Hi Rick, I have been testing Yu-Cheng's patchsets on AMD hardware and I am working on testing this version now. How are you testing this new series? I can partially test by calling the prctl enable for shadow stack directly from a program, but I'm not sure how useful that's going to be without the glibc support. Do you have a public repo with the necessary glibc changes to enable shadow stack early? Thanks, John
