1 Hi.
2
3 First I'd like to thank you all for the great work on making Gentoo Hardened!
4
5 Now to the question. I was wondering if there is a way to protect GOT
6 (besides having ET_DYN) in the way OpenBSD does
7 (http://undeadly.org/cgi?action=article&sid=20030126143902). If not,
8 what would you think on a similar patch for Hardened?
9
10 Also for some reason the ET_DYN on my amd64/hardened does only 40bit
11 (paxtest reports as guessed). Is there something that needs touching
12 in the toolchain to improve it?
13
14 Cheers.
