I also get the following (both of these are on logging in): Summary: SELinux is preventing /usr/bin/file "read" access on /usr/sbin/sendmail.sendmail. Detailed Description: [file has a permissive type (boinc_t). This access was not denied.] SELinux denied access requested by file. It is not expected that this access is required by file 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

Fixed in selinux-policy-3.7.19-13.fc13.noarch selinux-policy-3.7.19-13.fc13 has been submitted as an update for Fedora 13. http://admin.fedoraproject.org/updates/selinux-policy-3.7.19-13.fc13 selinux-policy-3.7.19-13.fc13 has been pushed to the Fedora 13 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update selinux-policy'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/selinux-policy-3.7.19-13.fc13 This still seems to occur with -13. Can you attach your latest avc messages.
sesearch -A -s boinc_t -t sendmail_exec_t
Found 3 semantic av rules:
allow boinc_t file_type : filesystem getattr ;
allow boinc_t mta_exec_type : file { read getattr execute open } ;
allow boinc_t mta_exec_type : lnk_file { read getattr } ;
I am using slightly newer policy
rpm -q selinux-policy
selinux-policy-3.7.19-14.fc13.noarch
Actually, it appears as if setroubleshoot is telling me about AVCs from the 9th of May for some reason. So is it fixed or not? Sorry, I'm making about as much sense as a hamster in a tumble dryer. Yes it is fixed now, sorry for the confusion. selinux-policy-3.7.19-33.fc13 has been submitted as an update for Fedora 13. http://admin.fedoraproject.org/updates/selinux-policy-3.7.19-33.fc13 selinux-policy-3.7.19-33.fc13 has been pushed to the Fedora 13 stable repository. If problems still persist, please make note of it in this bug report. |
