1 | Hi |
2 | |
3 | Some time ago we discussed that we should enable stack smashing |
4 | (-fstack-protector) by default. So we opened a bug to track this [1]. |
5 | The affected Gcc version will be 4.8.2 and newer. Only amd64, x86, mips, ppc, |
6 | ppc64 and arm will be affected by this change. |
7 | |
8 | You can turn off ssp by using the nossp USE flag or by adding |
9 | -fno-stack-protector to the CFLAGS and/or CXXFLAGS. We are using the same |
10 | patch as Debian/Ubuntu but with some Gentoo fixes. |
11 | |
12 | The patch will move the sed for the HARD_CFLAGS, ALLCFLAGS and |
13 | ALLCXXFLAGS from do_gcc_PIE_patches() to make_gcc_hard(). We will |
14 | make_gcc_hard() the default for all Gcc versions 4.8 and newer, and turn |
15 | it on or off with hardened_gcc_works() that will make some sanity checks. |
