F18 has this access. sesearch -A -s logwatch_t -t configfs_t Found 2 semantic av rules: allow logwatch_t filesystem_type : filesystem getattr ; allow logwatch_t filesystem_type : dir getattr ; Yes, it has been added to F18. no idea, some cron job? Package: (null) OS Release: Fedora release 17 (Beefy Miracle) OK, it seems it had nothing to do with writing to my SD card as I first reported. It happens daily after some cron job (I guess) has run. The denied access time stamp matches the arrival of my Logwatch mail. This keeps randomly appearing and I don't know why. It must have been triggered by a recent package update. Package: (null) OS Release: Fedora release 17 (Beefy Miracle) Backported from F17.

Allow logwatch to getattr on all dirs
It happens randomly but always after new log in. Package: (null) OS Release: Fedora release 17 (Beefy Miracle) Brand new Fedora 17 install Package: (null) OS Release: Fedora release 17 (Beefy Miracle) Nota Bene : !!! the command does the job just RIGHT !!! the issue is about the selinux comming up with a violation/detection warning, ONLY. But since "df" is a base command it should yes be allowed to oper And in the past SElinux was not raising up detection with this command... 1. Opened konsole 2. sudo df -f / or / and 1. opened the konsole 2. su 3. df -f / It happen the same - if konsole is openned for a while - if df receive otther parameters Package: (null) OS Release: Fedora release 17 (Beefy Miracle) *** Bug 890528 has been marked as a duplicate of this bug. *** I have the issue on Fedora 16. Will it be backported to F16 too? Yes. selinux-policy-3.10.0-166.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/FEDORA-2012-20544/selinux-policy-3.10.0-166.fc17 Package selinux-policy-3.10.0-166.fc17: * should fix your issue, * was pushed to the Fedora 17 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing selinux-policy-3.10.0-166.fc17' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2012-20544/selinux-policy-3.10.0-166.fc17 then log in and leave karma (feedback).

Description of problem: I was writing a .img file to an SD card using the Fedora Arm installer. Writing fails and the partitions get corrupted on the SD card, probably not related though.
