Expanding the list of "Hardened Packages"

Hi, This proposal was originally at https://fedorahosted.org/fesco/ticket/1104 (mitr asked me to move the discussion to fedora-devel to get more attention and feedback) ... http://fedoraproject.org/wiki/Hardened_Packages page mentions that "FESCo requires some packages to use PIE and relro hardening by default." It would be great if this list could be expanded to include even more packages which are at comparatively more risk of being exploited (locally or remotely). Such packages will typically include various system daemons, network daemons and network enabled applications. Lot of network daemons are already using PIE and RELRO (e.g. httpd, MariaDB). So a natural question is why packages in same "network daemons" class like PostgreSQL, Dovecot and MongoDB aren't being hardened? Some of the ways to implement this proposal are, 1. Hardening flags should be turned on (by default) for all packages which are at comparatively more risk of being exploited or which meet some well-defined criteria (suggestions welcome). "Packaging Guidelines" say that "Other packages may enable the flags at the maintainer's discretion." Thinking from a security perspective, I find "Hardening flags can only be disabled for other packages at the maintainer's discretion provided enough justification is given to FESCo" to be more appropriate. 2. An alternate approach is to come up with an expanded list of packages which should be hardened. Any feedback is welcome! -- Dhiru
