Hello all,

I have updated my gcc 3.4 profile (with SELinux) to gcc 4.3 profile (with a modified profile to support SELinux v2 policy).
After recompiling gcc+glibc, I obtain this :

gcc-config -l

[1] i686-pc-linux-gnu-4.3.4 *
[2] i686-pc-linux-gnu-4.3.4-hardenednopie
[3] i686-pc-linux-gnu-4.3.4-vanilla

[2] does not support support pie and I don't have a -hardened config.
So my question is : "[1] is the gcc hardened profile ?"
(when I test with paxtest, all is randomized)

Yes - actually I think it was the same on the gcc-3.4 profile also - the hardened profile was just the short named option and the other options are the ones which gradually work towards the "vanilla" specs by disabling certain hardening features

Ok I was confused with the howto (http://www.gentoo.org/proj/en/hardened/toolchain-upgrade-guide.xml ) :

Code Listing 2.5: Select hardened gcc

gcc-config -l
gcc-config <new gcc>-hardened
source /etc/profile
-----

Now I try to use the gcc 4.4 version on the git hardened-development and I have 2 questions : - espf is included in this version but not in gcc 4.3 version that are present in the portage tree ?
- espf is like ssp protection ?



Good luck
