Are you using ext4? Yup, anything wrong about that? [matej@viklef ~]$ mount /dev/mapper/vg00-lvRoot on / type ext4 (rw) /proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/sda1 on /boot type ext3 (rw) /dev/mapper/home on /home type ext3 (rw) tmpfs on /tmp type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) fusectl on /sys/fs/fuse/connections type fusectl (rw) gvfs-fuse-daemon on /home/matej/.gvfs type fuse.gvfs-fuse-daemon \ (rw,nosuid,nodev,user=matej) [matej@viklef ~]$ sudo -i [root@viklef ~]# ausearch -m AVC |grep sys_resource |grep denied |wc -l 1213 [root@viklef ~]# Well no, except this is a know problem with the ext4 and the kernel. It will be fixed in the next kernel update. *** This bug has been marked as a duplicate of bug 467216 *** Sorry, this is wrong de-duplication: a) this is Fedora 10 (originally Rawhide) bug with kernel 2.6.27, where as bug 467216 is RHEL5 with 2.6.18, b) this is still reproduceable with kernel 2.6.27.9-159.fc10.i686 and dnsmasq-2.45-1.fc10.i386 (not sure about Rawhide). Souhrn: SELinux is preventing dnsmasq (dnsmasq_t) "sys_resource" dnsmasq_t. Podrobný popis: SELinux denied access requested by dnsmasq. It is not expected that this access is required by dnsmasq 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.

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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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. |
