** Description changed: [Problem] - <1-2 sentence summary of the issue> + When SNMP_Session is used/required after Socket6, warnings are produced. [Impact] - <fill me in with explanation of severity and frequency of bug on users and justification for backporting the fix to the stable release> + Warnings are written to STDERR. Normally wouldn't be critical, except this module is mainly used by recurring programs such as mrtg and cricket. For example, in mrtg's packaged configuration, it is run every 5 minutes from cron, and the warnings will be delivered to root's mail spool, eventually filling the disk. [Development Fix] - <fill me in with an explanation of how the bug has been addressed in the development branch, including the relevant version numbers of packages modified in order to implement the fix. > + A patch has been submitted by Debian upstream, but upstream did not respond, and Debian handling has stalled. See http://bugs.debian.org/628804 . [Stable Fix] - <fill me in by pointing out a minimal patch applicable to the stable version of the package.> + Apply the patch contained in this bug. It is identical to the Debian patch, with the addition of debian/changelog entry. [Text Case] - <fill me in with detailed *instructions* on how to reproduce the bug. This will be used by people later on to verify the updated package fixes the problem.> - 1. - 2. - 3. - Broken Behavior: - Fixed Behavior: + 1. sudo apt-get install libsocket6-perl libsnmp-session-perl + 2. perl -MSocket6 -MSNMP_Session -e "" + Broken Behavior: + $ perl -MSocket6 -MSNMP_Session -e "" + Constant subroutine SNMP_Session::AF_INET6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. + at /usr/share/perl5/SNMP_Session.pm line 149 + Prototype mismatch: sub SNMP_Session::AF_INET6 () vs none at /usr/share/perl/5.14/Exporter.pm line 67. + at /usr/share/perl5/SNMP_Session.pm line 149 + Constant subroutine SNMP_Session::PF_INET6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. + at /usr/share/perl5/SNMP_Session.pm line 149 + Prototype mismatch: sub SNMP_Session::PF_INET6 () vs none at /usr/share/perl/5.14/Exporter.pm line 67. + at /usr/share/perl5/SNMP_Session.pm line 149 + Constant subroutine SNMPv1_Session::AF_INET6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. + at /usr/share/perl5/SNMP_Session.pm line 608 + Prototype mismatch: sub SNMPv1_Session::AF_INET6 () vs none at /usr/share/perl/5.14/Exporter.pm line 67. + at /usr/share/perl5/SNMP_Session.pm line 608 + Constant subroutine SNMPv1_Session::PF_INET6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. + at /usr/share/perl5/SNMP_Session.pm line 608 + Prototype mismatch: sub SNMPv1_Session::PF_INET6 () vs none at /usr/share/perl/5.14/Exporter.pm line 67. + at /usr/share/perl5/SNMP_Session.pm line 608 + $ + + Fixed Behavior: + $ perl -MSocket6 -MSNMP_Session -e "" + $ [Regression Potential] - <fill me in with a discussion of likelihood and potential severity of regressions and how users could get inadvertently affected.> + None known. AIUI, Socket6 is required, which exports {AF,PF}_INET6 among other things, and SNMP_Session would then try to re-import its namespace. Under previous version of Perl, this was silently ignored, but this produces a warning now. An unknown series of events could possibly cause {AF,PF}_INET6 to not be imported in the first place. [Original Report] While mrtg works ok, on every run it produces the following warnings: # env LANG=C /usr/bin/mrtg /etc/mrtg.cfg Subroutine SNMP_Session::pack_sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 149 Subroutine SNMP_Session::unpack_sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 149 Subroutine SNMP_Session::sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 149 Subroutine SNMPv1_Session::pack_sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 608 Subroutine SNMPv1_Session::unpack_sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 608 Subroutine SNMPv1_Session::sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 608 This happens even when "EnableIPv6: no" is present in mrtg.cfg. Because it's run every 5 minutes via cron, it's spamming the the user that ultimately gets root's cron mail.
