Description Carlos O'Donell 2023-06-27 20:45:20 UTC
For Fedora 39 we should turn on DT_RELR e.g. -Wl,-z,--pack-relative-relocs when building binaries.

This should also be documented in the top-level buildflags.md.

We already enable DT_RELR in glibc, and kernel support has been present since 2019.

The required binutils support is present since 2.38, and we are shipping 2.40 for Fedora 39.

The benefit here is that we will pack the relative relocs into less space and process them quickly in the dynamic loader.

Reproducible: Always

Comment 2 Fedora Release Engineering 2023-08-16 08:07:53 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.

Comment 3 Aoife Moloney 2024-11-08 10:54:24 UTC
This message is a reminder that Fedora Linux 39 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 39 on 2024-11-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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 EOL if it remains open with a
'version' of '39'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 39 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 Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 4 Aoife Moloney 2024-11-27 21:13:53 UTC
Fedora Linux 39 entered end-of-life (EOL) status on 2024-11-26.

Fedora Linux 39 is no longer maintained, which means that it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 Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

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