I searched in google but all I got was some questions in freebsd-security back from 2001 and an answer saying someone heard about a project like this, but no information at all. Is there any patch like PaX or Openwall available for FreeBSD? I dont want to discuss if its useless or not since there're a lot of techniques to defeat these protections. I'm not interested in patches for gcc or alikes either. Regards, -- Marcello Azambuja
