Re: ROP attack mitigation

Given that essentially no CPUs today support CET and given that CPUs remain deployed for perhaps 10 years, even more considering that CPU performance has plateaued, isn't there a moral imperative to mitigate ROP attacks using approaches other than just CET? The two I mentioned would help in the sho

RFC: Deprecate libstdc++ Policy-Based Data Structures

I'm including gcc@gcc.gnu.org here for visibility, but the discussion really belongs on the libstdc++ list so please limit replies to there. I'd like to discuss deprecating (and eventually removing) the libstdc++-v3/include/ext/pb_ds extensions. For information on them see https://gcc.gnu.org/onl

Hello there , I wanted to thank you for the bounty program you're providing here gcc.gnu.org/bugs/ Not all companies take this so seriously, but I think it's really important that companies are aware of it. I actually found about you thanks to a list of programs online. It's updated quite fre
