Description Benny Amorsen 2008-07-15 11:44:04 UTC
Description of problem: With previous init scripts (from 1.2) it was possible to easily override the standard up script, which made these things possible: *) Non-/32 netmask *) Multiple IP addresses per ucarp daemon The downside of overriding the standard scripts was that: *) Gratuituous ARP was done to 255.255.255.255 (which was useless) *) ucarp is unaware of the addresses, so it cannot do gratuituous ARP for them. This could be mitigated by doing gratuituous ARP in the script. There is one more problem with both the old and the new scripts. The VHID depends on the name of the configuration file. This is a problem for routers, where it is useful to keep the same VHID on all interfaces (obviously it is not correct to have the same VHID twice on the same interface). Version-Release number of selected component (if applicable): ucarp-1.4-1.fc9.i386 Ah, I just figured out that it is possible to add UPSCRIPT= to the configuration file. It would be nice if that was documented.

Comment 7 Benny Amorsen 2009-04-15 19:28:17 UTC
The UPSCRIPT option is gone, as far as I can tell. You can still use OPTIONS= to specify different files though, but it's not particularly smooth. The default scripts still cannot handle netmasks other than /32.
Comment 8 Gwyn Ciesla 2009-04-15 19:36:51 UTC
Is there a modification to the default scripts that could be made both to allow other netmasks, and not break existing behaviour?
Comment 9 Benny Amorsen 2009-04-16 09:24:33 UTC
Unfortunately staying compatible with existing behaviour probably requires modifications to ucarp. ucarp would need to accept 10.10.10.10/27 as a valid IP address but ignore the /27 except for passing to existing scripts. I have attached a proposed patch. Compile tested only; I have a similar patch in production which adds /32 if no netmask is passed, but that won't be compatible with existing scripts. The attached patch should be compatible with existing scripts, as long as the user does not use the new netmask functionality.
Comment 10 Benny Amorsen 2009-04-16 09:25:44 UTC
Created attachment 339817 [details] Patch to accept IP-addresses with masklen.
Comment 11 Gwyn Ciesla 2009-04-17 13:45:06 UTC
This looks like the sort of thing that might be better done upstream. I'll contact the author and get his $0.02.
Comment 12 Bug Zapper 2009-06-10 02:05:30 UTC
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. 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 '9'. 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 9'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 9 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Comment 13 Bug Zapper 2009-07-14 18:10:23 UTC
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
Comment 14 Robert Scheck 2016-05-02 16:23:25 UTC
Jon, did you ever hear from upstream? The patch is what I would need here...
Comment 15 Gwyn Ciesla 2016-05-03 13:00:11 UTC
I didn't. I would be willing to try this patch out, if it can be extensively tested. I'd be willing to post builds for specified releases architectures.
