mozilla_plugin_selinux(8)SELinux Policy mozilla_plugimozilla_plugin_selinux(8)NAMEmozilla_plugin_selinux - Security Enhanced Linux Policy for the
mozilla_plugin processes
DESCRIPTION
Security-Enhanced Linux secures the mozilla_plugin processes via flexi‐
ble mandatory access control.
The mozilla_plugin processes execute with the mozilla_plugin_t SELinux
type. You can check if you have these processes running by executing
the ps command with the -Z qualifier.
For example:
ps -eZ | grep mozilla_plugin_t
ENTRYPOINTS
The mozilla_plugin_t SELinux type can be entered via the mozilla_plug‐
in_exec_t file type.
The default entrypoint paths for the mozilla_plugin_t domain are the
following:
/usr/lib/xulrunner[^/]*/plugin-container, /usr/lib/nspluginwrap‐
per/npviewer.bin, /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
/usr/lib/firefox/plugin-container
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
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 mozilla_plugin_t can be used to make the
process type mozilla_plugin_t permissive. SELinux does not deny access
to permissive process types, but the AVC (SELinux denials) messages are
still generated.
BOOLEANS
SELinux policy is customizable based on least access required.
mozilla_plugin policy is extremely flexible and has several booleans
that allow you to manipulate the policy and run mozilla_plugin with the
tightest access possible.

these file types. Note the processes UID still need to have DAC per‐

FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
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.
STANDARD FILE CONTEXT
SELinux defines the file context types for the mozilla_plugin, if you
wanted to store files with these types in a diffent paths, you need to
execute the semanage command to sepecify alternate labeling and then
use restorecon to put the labels on disk.
semanage fcontext -a-t mozilla_plugin_config_exec_t
'/srv/mozilla_plugin/content(/.*)?'
restorecon -R -v /srv/mymozilla_plugin_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
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 transi‐
tion an executable to the mozilla_plugin_t domain.
Paths:
/usr/lib/xulrunner[^/]*/plugin-container, /usr/lib/nspluginwrap‐
per/npviewer.bin, /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
/usr/lib/firefox/plugin-container
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 data‐
base. You will need to use restorecon to apply the labels.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
