Souhrn: SELinux is preventing arping (netutils_t) "sys_module" netutils_t. Podrobný popis: SELinux denied access requested by arping. It is not expected that this access is required by arping and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Povolení přístupu: You can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

Probably somehow related to bug 483212 ... and the issue is of course bug 483212 comment 12
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I'm unable to reproduce the bug. I went through the code I didn't found any module handling. The arping.c contains ioctl function call. The same ioctl call contains radvd (bug #495189) where the AVC denial is a result of testing interface if the interface is activated. I suppose it could be similar problem. Jiri
Due to comment #3 changed to selinux-policy
New kernels this is module_request instead of sys_module. In F11 policy you can feel free to dontaudit or to allow. In F12 and later policy we shouldn't be doing either....
Fixed in selinux-policy-3.6.12-90.fc11
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '11'. 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 11'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 11 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
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.
