Replace the current _FORTIFY_SOURCE=2 with _FORTIFY_SOURCE=3 to improve mitigation of security issues arising from buffer overflows in packages in Fedora.

Current status

Scope

  • Proposal owners:

Build all packages and report failures.

  • Other developers:

Fix bugs filed for build failures.

Upgrade/compatibility impact
