The first access is currently allowed in F18. #============= staff_gkeyringd_t ============== #!!!! This avc is allowed in the current policy allow staff_gkeyringd_t data_home_t:dir read; The second access is actually a leak, and should not be causing gpg any problems. I will allow it in F19. Miroslav can you back port. Backported.

Description of problem: Deja-dup is a small utility from GNOME, which backs up data. One of the features of Deja-dup is to encrypt data before storing it on remote location. Encryption is done via GPG (GNU Privacy Guard) with user’s private key. SELinux fires two AVCs when encrypting: 1. Preventing ssh-agent to read from .local/share/keystore (gnome-keyring, a place where a passphrase for the private key is stored) 2. Preventing gpg to write to .cache (a cache directory, which Deja-dup chose) It’s much safer to allow Deja-dup to encrypt data before storing it on remote location, you know. Version-Release number of selected component (if applicable): Fedora 17. selinux-policy-3.10.0-166.fc17.noarch selinux-policy-targeted-3.10.0-166.fc17.noarch Expected results: No AVC denials on backing up. Additional info: * Switch to staff_u:staff_r before.
