6 mozilla_plugin_selinux - Security Enhanced Linux Policy for the
7 mozilla_plugin processes
8
10 Security-Enhanced Linux secures the mozilla_plugin processes via flexi‐
11 ble mandatory access control.
12 The mozilla_plugin processes execute with the mozilla_plugin_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep mozilla_plugin_t
20
24 The mozilla_plugin_t SELinux type can be entered via the mozilla_plug‐
25 in_exec_t file type.
26 The default entrypoint paths for the mozilla_plugin_t domain are the
28 following:
29 /usr/lib/xulrunner[^/]*/plugin-container, /usr/lib/nspluginwrap‐
31 per/npviewer.bin, /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
32 /usr/libexec/WebKitPluginProcess, /usr/lib/firefox/plugin-container
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 mozilla_plugin policy is very flexible allowing users to setup their
42 mozilla_plugin processes in as secure a method as possible.
43 The following process types are defined for mozilla_plugin:
45 mozilla_plugin_t, mozilla_plugin_config_t
47 Note: semanage permissive -a mozilla_plugin_t can be used to make the
49 process type mozilla_plugin_t permissive. SELinux does not deny access
50 to permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
55 SELinux policy is customizable based on least access required.
56 mozilla_plugin policy is extremely flexible and has several booleans
57 that allow you to manipulate the policy and run mozilla_plugin with the
58 tightest access possible.
59 If you want to allow mozilla plugin domain to bind unreserved tcp/udp
63 ports, you must turn on the mozilla_plugin_bind_unreserved_ports bool‐
64 ean. Disabled by default.
65 setsebool -P mozilla_plugin_bind_unreserved_ports 1
67 If you want to allow mozilla plugin domain to connect to the network
71 using TCP, you must turn on the mozilla_plugin_can_network_connect
72 boolean. Enabled by default.
73 setsebool -P mozilla_plugin_can_network_connect 1

94 setsebool -P mozilla_plugin_use_spice 1
96 If you want to allow users to resolve user passwd entries directly from
100 ldap rather then using a sssd server, you must turn on the authlo‐
101 gin_nsswitch_use_ldap boolean. Disabled by default.
102 setsebool -P authlogin_nsswitch_use_ldap 1
104 If you want to allow all domains to execute in fips_mode, you must turn
108 on the fips_mode boolean. Enabled by default.
109 setsebool -P fips_mode 1
111 If you want to allow confined applications to run with kerberos, you
115 must turn on the kerberos_enabled boolean. Enabled by default.
116 setsebool -P kerberos_enabled 1
118 If you want to allow system to run with NIS, you must turn on the
122 nis_enabled boolean. Disabled by default.
123 setsebool -P nis_enabled 1

129 you must turn on the nscd_use_shm boolean. Disabled by default.
130 setsebool -P nscd_use_shm 1

160 setsebool -P use_samba_home_dirs 1

166 The SELinux process type mozilla_plugin_t can manage files labeled with
167 the following file types. The paths listed are the default paths for
168 these file types. Note the processes UID still need to have DAC per‐
169 missions.

283 SELinux requires files to have an extended attribute to define the file
284 type.
285 You can see the context of a file using the -Z option to ls
287 Policy governs the access confined processes have to these files.
289 SELinux mozilla_plugin policy is very flexible allowing users to setup
290 their mozilla_plugin processes in as secure a method as possible.
291 STANDARD FILE CONTEXT
293 SELinux defines the file context types for the mozilla_plugin, if you
295 wanted to store files with these types in a diffent paths, you need to
296 execute the semanage command to sepecify alternate labeling and then
297 use restorecon to put the labels on disk.
298 semanage fcontext -a -t mozilla_plugin_rw_t '/srv/mymozilla_plugin_con‐
300 tent(/.*)?'
301 restorecon -R -v /srv/mymozilla_plugin_content
302 Note: SELinux often uses regular expressions to specify labels that
304 match multiple files.
305 The following file types are defined for mozilla_plugin:
307 mozilla_plugin_config_exec_t
311 - Set files with the mozilla_plugin_config_exec_t type, if you want to
313 transition an executable to the mozilla_plugin_config_t domain.
314 mozilla_plugin_exec_t
318 - Set files with the mozilla_plugin_exec_t type, if you want to transi‐
320 tion an executable to the mozilla_plugin_t domain.
321 Paths:
324 /usr/lib/xulrunner[^/]*/plugin-container, /usr/lib/nspluginwrap‐
325 per/npviewer.bin, /usr/bin/nspluginscan, /usr/bin/nspluginviewer,
326 /usr/libexec/WebKitPluginProcess, /usr/lib/firefox/plugin-con‐
327 tainer
328 mozilla_plugin_rw_t
331 - Set files with the mozilla_plugin_rw_t type, if you want to treat the
333 files as mozilla plugin read/write content.
334 mozilla_plugin_tmp_t
338 - Set files with the mozilla_plugin_tmp_t type, if you want to store
340 mozilla plugin temporary files in the /tmp directories.
341 mozilla_plugin_tmpfs_t
345 - Set files with the mozilla_plugin_tmpfs_t type, if you want to store
347 mozilla plugin files on a tmpfs file system.
348 Note: File context can be temporarily modified with the chcon command.
352 If you want to permanently change the file context you need to use the
353 semanage fcontext command. This will modify the SELinux labeling data‐
354 base. You will need to use restorecon to apply the labels.
355
358 semanage fcontext can also be used to manipulate default file context
359 mappings.
360 semanage permissive can also be used to manipulate whether or not a
362 process type is permissive.
363 semanage module can also be used to enable/disable/install/remove pol‐
365 icy modules.
366 semanage boolean can also be used to manipulate the booleans
368 system-config-selinux is a GUI tool available to customize SELinux pol‐
371 icy settings.
