Description Nils Philippsen 2010-08-04 09:00:13 EDT
Description of problem:
The sane-backends package uses non-IPv6-aware functions at some places and should use the more modern, protocol-agnostic pendants instead on Linux. See http://www.akkadia.org/drepper/userapi-ipv6.html for details.

Additional info:
The old code shouldn't be deleted as it must be used on platforms that don't have an IPv6 stack such as OS/2 (according to the changelog).
Comment 1 Fedora End Of Life 2013-04-03 14:52:40 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

More information and reason for this action is here:
Comment 2 Fedora End Of Life 2015-01-09 11:17:39 EST
This message is a notice that Fedora 19 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 19. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.

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.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 19 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 this bug is closed as described in the policy above.

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.
Comment 3 Fedora End Of Life 2015-02-17 08:18:59 EST
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 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no longer maintained, which means that it will not receive any further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

Thank you for reporting this bug and we are sorry it could not be fixed.
Comment 4 Nils Philippsen 2016-06-09 04:39:08 EDT
Reopening as FutureFeature to keep track of this.
Comment 5 Nils Philippsen 2016-10-14 05:33:22 EDT
This is a significant effort, not just coding-wise: sane-backends at least semi-officially supports platforms like OS/2 which don't have some of the IPv6-aware functions, so there would need to be some discussion if to abandon them, or whether to provide fallback code for them.

I don't expect to work on this in the foreseeable future, therefore I'll close the bug.
