Dominick, have we ever had a discuss on this issue or am I wrong? I thought we had changed pam_mount to execute /bin/umount rather then /bin/umount.crypt? (In reply to Miroslav Grepl from comment #2) > I thought we had changed pam_mount to execute /bin/umount rather then > /bin/umount.crypt? It seems that this was reverted by upstream when utab support became a requirement to get umount call umount.crypt. What pam_mount.conf.xml do you use? I upgraded to latest selinux-policy-3.12.1-193.fc20 and I do not see any AVC denial. On the other hand, I'm struggling with bug 1086822 even with older selinux-policy and I assume that in my case, the attempt to umount does not even happen. What is your exact configuration that allows you to trigger the issue? I prepared an initial patch for pam_mount to get plain umount work again. I just submitted in upstream for review. pam_mount-2.14-4.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/pam_mount-2.14-4.fc19 pam_mount-2.14-4.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/pam_mount-2.14-4.fc20 pam_mount-2.14-4.fc21 has been submitted as an update for Fedora 21. https://admin.fedoraproject.org/updates/pam_mount-2.14-4.fc21 Package pam_mount-2.14-4.fc21: * should fix your issue, * was pushed to the Fedora 21 testing repository, * should be available at your local mirror within two days.
