- Add two new configure flags:
- --enable-gcc-hardening
- This turns on gcc compile time hardening options. It ensures that
- signed ints have defined behavior (-fwrapv), -D_FORTIFY_SOURCE=2 is
- enabled (requiring -O2), stack smashing protection with canaries
- (-fstack-protector-all), ASLR protection if supported by the kernel
- (-fPIE, -pie). Additional security related warnings are enabled.
- Verified as working on Mac OS X and Debian Lenny.
- --enable-linker-hardening
- This turns on ELF specific hardening features (relro, now). This does
- not work with Mac OS X or any other non-ELF binary format.
