Security-Enhanced Linux secures the mozilla_plugin processes via flexible mandatory access control.
If you want to allow unconfined users to transition to the Mozilla plugin domain when running xulrunner plugin-container, you must turn on the unconfined_mozilla_plugin_transition boolean.
setsebool -P unconfined_mozilla_plugin_transition 1
If you want to allow mozilla_plugins to create random content in the users home directory, you must turn on the mozilla_plugin_enable_homedirs boolean.
setsebool -P mozilla_plugin_enable_homedirs 1
If you want to allow mozilla plugin domain to connect to the network using TCP, you must turn on the mozilla_plugin_can_network_connect boolean.
setsebool -P mozilla_plugin_can_network_connect 1
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the mozilla_plugin_config_t, mozilla_plugin_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the mozilla_plugin_config_t, mozilla_plugin_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux mozilla_plugin policy is very flexible allowing users to setup their mozilla_plugin processes in as secure a method as possible.
The following file types are defined for mozilla_plugin:
mozilla_plugin_config_exec_t
- Set files with the mozilla_plugin_config_exec_t type, if you want to transition an executable to the mozilla_plugin_config_t domain.
mozilla_plugin_exec_t
- Set files with the mozilla_plugin_exec_t type, if you want to transition an executable to the mozilla_plugin_t domain.
mozilla_plugin_rw_t
- Set files with the mozilla_plugin_rw_t type, if you want to treat the files as mozilla plugin read/write content.
mozilla_plugin_tmp_t
- Set files with the mozilla_plugin_tmp_t type, if you want to store mozilla plugin temporary files in the /tmp directories.
mozilla_plugin_tmpfs_t
- Set files with the mozilla_plugin_tmpfs_t type, if you want to store mozilla plugin files on a tmpfs file system.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux mozilla_plugin policy is very flexible allowing users to setup their mozilla_plugin processes in as secure a method as possible.
The following process types are defined for mozilla_plugin:
mozilla_plugin_config_t, mozilla_plugin_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive proce
