           Summary: perl should be a hardened build
           Product: Fedora

perl is often used for long running services (mailgraph, smokeping, postgrey..)
as well as called from webservers with untrusted input

so it should be "Full RELRO" and PIE
http://fedoraproject.org/wiki/Packaging:Guidelines#PIE
______________________________________________________

If your package meets any of the following criteria you MUST enable the PIE
compiler flags:

Your package is long running. This means it's likely to be started and keep
running until the machine is rebooted, not start on demand and quit on idle.

Your package has suid binaries, or binaries with capabilities.

Your package runs as root.

If your package meets the following criteria you should consider enabling the
PIE compiler flags:

Your package accepts/processes untrusted input.

Have you considered the perl is also used for short-time scripts? Are you going
to promote any interpreter (python, tcl, bash, pl, etc.) for hardening?

clearly yes and sooner or later hopefully the whole distribution get hardened
and prelink banned, until then at least "checksec --proc-all" on servers should
not list anything without "Full RELRO" and PIE-code

--- Comment #3 from Marcela Mašláňová  ---
I was speaking to the Security team, because I was interested in their point of
view. The common practice until now was "add the full relro to long time
running apps, especially daemons".

In opinion of Security team, languages don't need full relro if they don't
write into pointers like this example:
http://cs.potsdam.edu/cgi-bin/man/man2html?Glib::Object+3
Glib::Object->new_from_pointer

Therefore Perl is a good candidate for full relro. I would like to see analysis
of slowdown of Perl examples and also all major components before we start
changing partial relro into full relro. I'd rather see same approach for whole
distribution than accidentally changing some apps.

--- Comment #5 from Fedora End Of Life  ---
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '18'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior to Fedora 18's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

security first

"grep" become noticeable slower in F23 as hardened build, in F24 it is stil
hardened but has the same impressive performance than in F22 or older releases,
so something got optimized

Perl 5.26.0 is built as PIE, it's still missing full RELRO. Merging this
request to similar bug #1238804.
