Description of problem: after adding an ipv6 ip with "ip addr add" you can not add a route for that ip for 1.69 seconds. Version-Release number of selected component (if applicable): ip utility, iproute2-ss120319 How reproducible: 100% Steps to Reproduce: i wrote a bash script to demo the problem: script will add an ip (2001::5) then attempt to add a route for that ip as fast as possible (with timestamps). CHANGE em1 TO YOUR INTERFACE (two occurrences) ip addr replace 2012::5 dev em1 && while :; do echo "`date +%s-%N` `ip -6 route replace 2012::/64 dev em1 src 2012::5 2>&1`" >> temp; done contents to temp will start with a few hundred (200-400) lines of: Example: 1345085902-895959857 RTNETLINK answers: Invalid argument then change once the route is successfully added Example: 1345085902-895959857 It takes about 1.69 seconds on average before a route can be added which is annoying for scripts. Actual results: delay Expected results: no delay (works for ipv4 just fine) Additional info:
This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '17'. 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 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 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 17'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 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. Thank you for reporting this bug and we are sorry it could not be fixed.
