This is pretty cool stuff, thanks for sharing.
I've been following tedu's blog and one of the interesting topics that came up in OpenBSD was W^X memory, which apparently didn't get along well with JIT compilers, so they devised a new memory protection scheme called now-or-never execution.
Outside of OpenBSD land, do you see either of these two (W^X, nonexec) being used in a future version of Adobe Flash Player? (and/or in Chrome/Firefox?)
- acqq 11y agoAs far as I understand http://www.tedunangst.com/flak/post/now-or-never-exec http://www.tedunangst.com/flak/post/now-or-never-exec is not used even in OpenBSD.
- protomyth 11y agoOpenBSD implements W^X in the kernel on various architectures (AMD64 was discussed here https://news.ycombinator.com/item?id=8884370 https://news.ycombinator.com/item?id=8884370 )
