Created attachment 364448 [details] Fix modprobing ip_vs module Description of problem: Keepalived segfaults when the ip_vs module isn't loaded. Version-Release number of selected component (if applicable): [ruben@lb1 ~]$ rpm -q keepalived keepalived-1.1.17-1.fc11.x86_64 How reproducible: [ruben@lb1 ~]$ sudo service keepalived start Actual results: The following messages fill up my logfile: __ratelimit: 744 callbacks suppressed keepalived[9878]: segfault at 0 ip 000000000040bc05 sp 00007fffb3b0aeb0 error 6 in keepalived[400000+25000] keepalived[9880]: segfault at 0 ip 000000000040bc05 sp 00007fffb3b0aeb0 error 6 in keepalived[400000+25000] keepalived[9882]: segfault at 0 ip 000000000040bc05 sp 00007fffb3b0aeb0 error 6 in keepalived[400000+25000] keepalived[9884]: segfault at 0 ip 000000000040bc05 sp 00007fffb3b0aeb0 error 6 in keepalived[400000+25000] Expected results: A working keepalived. Additional info: keepalived tries to modprobe ip_vs.ko at startup (in ipvswrapper.c) with modprobe -s -k. I guess modprobe dropped the -k option a while ago, so this command fails. I've attached a patch which fixes this.
Hi Matthias, Have you had a chance to look at this ticket? If not, let me know and I'll update keepalived myself (if you don't mind).
ping?
Thanks for the report and the patch! Sorry for taking so long, I've been wanting to perform proper testing for this one, and I've been preparing the update to 1.1.19 too. I really hope to get it over with in the next few days.
I've just rebuilt 1.1.19 for devel, in case you can test and give feedback on it : http://koji.fedoraproject.org/koji/taskinfo?taskID=1828267 I'll be testing it shortly on systems with real (and complex) configurations, after which I'll push the update to other branches if all went well, but your feedback would also be very welcome!
Thanks! I'll give it a shot tomorrow on our ldap cluster, and let you know how it works.
Hey Matthias, Just tested it out (did a rebuild for F-11), failover and everything, and it works fine.
