Description of problem: Some plugin is trying to access someone else's home directory. Firefox is running as jweiss, but it's trying to getattr in /home/.ecryptfs. I think it's the google talk plugin doing this, but I'm not sure whose job it is to avoid this kind of access. I could definitely believe this is google's fault, but thought I'd report it here just in case. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Set up your home directory with ecryptfs 2. install google talk plugin 2. Run firefox 3. load http://plus.google.com or gmail.com Actual results: Expected results: Additional info: SELinux is preventing /usr/lib64/xulrunner/plugin-container from getattr access on the file /home/.ecryptfs/jweiss/.Private/ECRYPTFS_FNEK_ENCRYPTED.FWbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPO-5VRk7yZ89QHJRGgeH4GU--/ECRYPTFS_FNEK_ENCRYPTED.FXbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPcu.qfiED.KTJst0Fq02Ep.3Vr7yJ01I5Mdd44yuIlVQ-/ECRYPTFS_FNEK_ENCRYPTED.FXbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPW4-NJDEp13KCjDKdqTfDAe3FoLPJzZhdBl5l4Xp.3MU-. ***** Plugin restorecon (57.3 confidence) suggests ************************* If you want to fix the label. /home/.ecryptfs/jweiss/.Private/ECRYPTFS_FNEK_ENCRYPTED.FWbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPO-5VRk7yZ89QHJRGgeH4GU--/ECRYPTFS_FNEK_ENCRYPTED.FXbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPcu.qfiED.KTJst0Fq02Ep.3Vr7yJ01I5Mdd44yuIlVQ-/ECRYPTFS_FNEK_ENCRYPTED.FXbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPW4-NJDEp13KCjDKdqTfDAe3FoLPJzZhdBl5l4Xp.3MU- default label should be ecryptfs_t.

Then you should report this as a bug. You can generate a local policy module to allow this access.

Yes, the plugin-container (which runs the plugin) only runs the pluig, it's just the proxy between firefox and plugin itself. So please report at google or disable the access.
