The openwall LSM patch does not prevent buffer overflows.  That's 
currently impossible to do with the LSM framework.

Also, see the lkml archives for why the openwall non-executable stack
patch will never be accepted into the main kernel tree (hint, it's 
just a work around, and doesn't solve the real problem.)

And there's things like the StackGuard or ProPolice gcc patches that
might be better to point people at.  However, that's not a kernel
patch/feature, so would not fall under the CGL spec :)
