Description Steve Grubb 2011-07-21 14:47:05 UTC

Description of problem:
The shadow-utils program contains setuid programs. We would like them to be built with PIE and FULL RELRO support if possible. Partial RELRO is OK if all attempts at making it FULL RELRO run into problems.

Additional info:
PIE flags mean -fPIE -DPIE passed to gcc on compile
FULL RELRO requires these passed at link:
-Wl,-z,relro -Wl,-z,bind_now
