Podsumowanie: SELinux is preventing /usr/lib64/chromium-browser/chrome-sandbox "read" access on /proc. Szczegółowy opis: [chrome-sandbox posiada typ zezwalania (chrome_sandbox_t). Ten dostęp nie został odmówiony.] SELinux denied access requested by chrome-sandbox. It is not expected that this access is required by chrome-sandbox 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. Zezwalanie na dostęp: You can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug report.

Below is a sumary from SELinux preventing chromium web browser from launching. Summary: SELinux is preventing /usr/lib64/chromium-browser/chrome-sandbox "read" access on /proc. Detailed Description: [chrome-sandbox has a permissive type (chrome_sandbox_t). This access was not denied.] SELinux denied access requested by chrome-sandbox. It is not expected that this access is required by chrome-sandbox 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) Please file a bug report.

You can add these rules for now using # grep avc /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Fixed in selinux-policy-3.6.32-48.fc12.noarch

Unfortunately, after updating selinux the problem remains. If you need any more informations let me know what I can do to give you it.
rpm -q selinux-policy-targeted What avc are you still seeing?
$ rpm -q selinux-policy-targeted selinux-policy-targeted-3.6.32-49.fc12.noarch SELinux is preventing /usr/lib64/chromium-browser/chrome-sandbox "read" access on /proc.
selinux-policy-targeted-3.6.32-52.fc12.noarch yum update selinux-policy-targeted --enablerepo=updatest-testing
$ su -c 'yum --enablerepo=updates-testing update selinux-policy-targeted' gave me "no packets to update".
Well it should be there soon.
$ rpm -qe selinux-policy-targeted selinux-policy-targeted-3.6.32-52.fc12.noarch Problem is finally fixed.
