" http://marc.theaimsgroup.com/?l=openbsd-cvs&m=103881967909595&w=2Wow, I had mentioned this previously for GCC 3.2, but this is the base system. Hurray! Check out the link about ProPolice and see how it works, it's some cool stuff!
quote:"Log message: Import propolice (http://www.trl.ibm.com/projects/security/ssp), a stack attack protection scheme, into gcc.
This protection is enabled by default. It can be turned off by using the -fno-stack-protector flag.
Code by Hiroaki Etoh (etoh at jp dot ibm dot com); work on openbsd-specific integration by fgsch@, deraadt@ and myself; tests by fgsch@, naddy@ and myself; beer drinking by myself.
Please note that system upgrades with this new code will require a new libc and ld.so to be build and installed before the propolice-enabled compiler can be installed."
