Hello, I saw that alert today in my netbook running Fedora 10 i386 all partitions are formatted with ext4 except /boot: PolicyKit-0.9-4.fc10.i386 kernel-2.6.27.12-170.2.5.fc10.i686 selinux-policy-targeted-3.5.13-40.fc10.noarch libselinux-utils-2.0.73-1.fc10.i386 libselinux-python-2.0.73-1.fc10.i386 selinux-policy-3.5.13-40.fc10.noarch maybe is related to bug https://bugzilla.redhat.com/show_bug.cgi?id=478299 but I'm running the kernel fix from that bug report and setroubleshooter is running perfectly I triggered running sudo Summary: SELinux is preventing polkit-read-aut (polkit_auth_t) "getattr" fs_t. Detailed Description: SELinux denied access requested by polkit-read-aut. It is not expected that this access is required by polkit-read-aut 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. Allowing Access: 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.

According to the package changelog, it should be fixed since selinux-policy-3.6.12-75. Here's a Koji build for 3.6.12-78: http://koji.fedoraproject.org/koji/buildinfo?buildID=127255 It's not yet in any updates repository. # rpm -q PolicyKit PolicyKit-0.9-6.fc11.i586 # rpm -qa | grep selinux selinux-policy-3.6.12-78.fc11.noarch libselinux-python-2.0.80-1.fc11.i586 selinux-policy-targeted-3.6.12-78.fc11.noarch libselinux-2.0.80-1.fc11.i586 libselinux-utils-2.0.80-1.fc11.i586 It's OK now. No alerts. Thanks. The alert appeared today on an updated Fedora 10. Perhaps, PolicyKit needs to be updated for Fedora 10 as well ?? If the previous comment is correct, then it's likely to be an issue with PolicyKit rather than other packages. In truth, I do not even know how to reproduce it... This AVC denial is very likely caused by a kernel bug in BSD accounting. Will be fixed in 2.6.32 by: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d8e180dcd5bbbab9cd3ff2e779efcf70692ef541 I'll ask the -stable team to apply it to 2.6.31.y, so F12 can have it fixed this way. This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. 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 '10'. 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 10'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 10 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 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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. |
