Any chance you'll submit that to the upstream kernel too? Very cool to see ASLR working in ARM! Any chance you’ll submit that to the upstream kernel too?

That said, I'd like to see the changes in the upstream kernel, since convincing the Ubuntu (or any distro) kernel team to carry PaX would be potentially more difficult. I am aware of the PaX ARM ASLR, which is why I was hoping to see those missing ASLR bits go upstream -- it is technically possible to accomplish, so getting it in is the next step. And on that note, I'd love to see the upstream ASLR improved to have a wider bit range randomized. But that's a whole other story.

We'll be adding more features to ARM regardless of whatever upstream decides to do. -Brad Have you tried PaX’s ASLR support on ARM?
