No, no, no ... please do *not do this.
NetBSD's libssp is a minomer for two things:
- The support for the stack protector: We already have that in lib/libc/secure/.
- Support for FORTIFY_SOURCE: This was almost finished for GSoC 2015 but is now abandoned.
FORTIFY_SOURCE doesn't have anything to do with the stack protector, the NetBSD guys just didn't think of a better place to put it. It does happen that the "strong" stack protector catches most of the issues that FORTIFY_SOURCE was meant to catch.
The NetBSD FORTIFY_SUPPORT stuff is also very outdated and doesn't support clang at all.
Hmm ... we have to investigate exactly what the libssp included in GCC does. It maybe that it is something very basic to support the stack protector, or it something that is not used at all.
