Description of problem: http://fedoraproject.org/wiki/Packaging:Guidelines#PIE says that "you MUST enable the PIE compiler flags if your package is long running ...". However, currently redis is not being built with PIE flags. This is a clear violation of the packaging guidelines. This issue (in its wider scope) is being discussed at, https://fedorahosted.org/fesco/ticket/1104 https://lists.fedoraproject.org/pipermail/devel/2013-March/180827.html Version-Release number of selected component (if applicable): redis-2.6.7-2.fc19.x86_64.rpm How reproducible: You can use following programs to check if a package is hardened: http://people.redhat.com/sgrubb/files/rpm-chksec OR https://github.com/kholia/checksec Steps to Reproduce: Get scanner.py from https://github.com/kholia/checksec $ ./scanner.py redis-2.6.7-2.fc19.x86_64.rpm redis,redis-2.6.7-2.fc19.x86_64.rpm,/usr/bin/redis-benchmark,NX=Enabled,CANARY=Enabled,RELRO=Partial,PIE=Disabled,RPATH=Disabled,RUNPATH=Disabled,FORTIFY=Enabled,CATEGORY=network-ip redis,redis-2.6.7-2.fc19.x86_64.rpm,/usr/bin/redis-check-aof,NX=Enabled,CANARY=Enabled,RELRO=Partial,PIE=Disabled,RPATH=Disabled,RUNPATH=Disabled,FORTIFY=Enabled,CATEGORY=None redis,redis-2.6.7-2.fc19.x86_64.rpm,/usr/bin/redis-check-dump,NX=Enabled,CANARY=Enabled,RELRO=Partial,PIE=Disabled,RPATH=Disabled,RUNPATH=Disabled,FORTIFY=Enabled,CATEGORY=None redis,redis-2.6.7-2.fc19.x86_64.rpm,/usr/bin/redis-cli,NX=Enabled,CANARY=Enabled,RELRO=Partial,PIE=Disabled,RPATH=Disabled,RUNPATH=Disabled,FORTIFY=Enabled,CATEGORY=network-ip redis,redis-2.6.7-2.fc19.x86_64.rpm,/usr/sbin/redis-server,NX=Enabled,CANARY=Enabled,RELRO=Partial,PIE=Disabled,RPATH=Disabled,RUNPATH=Disabled,FORTIFY=Enabled,CATEGORY=network-ip
Created attachment 747519 [details] this should enable PIE

In my limited testing, I couldn't find any performance difference between the PIE and no-PIE builds. The benchmarking script is at https://github.com/kholia/unSPEC/blob/master/redis/redis_bench.py
