Current stable =hardened-sources-3.8.3 are affected by bug described here: https://bugs.gentoo.org/show_bug.cgi?id=459268#c5 so make some services like vsftpd with ssl support unusable. I've tested 3.8.6 and it's not affected. Thank you.
Blueness (and other hardened kernel devs if there is any hidding) your take ;)
