I've rebuilt my mls policy to include gnome, mozilla and some other modules to get the correct labeling on some vital directories like ~/.gconf. However I am concerned about some of the remaining unlabel files and directories and the impact on the users experience. It seems that the main issue is that since in the default targeted policy these files get labeled unconfined_u:object_r:user_home_t:s0 and then when you switch to MLS because the unconfined modules is not included they get relabel to system_u:object_r:unlabeled_t:s15:c0.c1023. Would it be possible/reasonable to only change the undefined portion of the context to something else for example only change unconfined_u to system_u instead of changing and losing the whole context? -rw------- tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .bash_history drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .cache drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .config drwx------ tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .dbus drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 Desktop drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 Documents drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 Download -rw------- tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .esd_auth drwx------ tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .gnome2_private drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 Music drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .nautilus drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 Pictures drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 Public -rw------- tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .pulse-cookie drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 Templates drwxrwxr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .tomboy -rw-rw-r-- tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .tomboy.log drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 Videos drwxr-xr-x tedx tedx system_u:object_r:unlabeled_t:s15:c0.c1023 .wapi Ted -- This message was distributed to subscribers of the selinux mailing list.
