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
13 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
17 For example:
18
19 ps -eZ | grep mozilla_plugin_t
20
21
22
24 The mozilla_plugin_t SELinux type can be entered via the mozilla_plug‐
25 in_exec_t file type.
26
27 The default entrypoint paths for the mozilla_plugin_t domain are the
28 following:
29
30 /usr/lib(64)?/xulrunner[^/]*/plugin-container
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 mozilla_plugin policy is very flexible allowing users to setup their
40 mozilla_plugin processes in as secure a method as possible.
41
42 The following process types are defined for mozilla_plugin:
43
44 mozilla_plugin_config_t, mozilla_plugin_t
45
46 Note: semanage permissive -a mozilla_plugin_t can be used to make the
47 process type mozilla_plugin_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 mozilla_plugin policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run mozilla_plugin with the
56 tightest access possible.
57
58
59
60 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63 setsebool -P allow_domain_fd_use 1
64
65
66
67 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69
70 setsebool -P allow_kerberos 1
71
72
73
74 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.

77 setsebool -P allow_ptrace 1
78
79

82 allow_ypbind boolean. Disabled by default.
83
84 setsebool -P allow_ypbind 1
85
86
87
88 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.

93
94
95

100
101
102
103 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105
106 setsebool -P global_ssp 1
107
108
109
110 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.

114
115
116
117 If you want to allow unconfined users to transition to the Mozilla
118 plugin domain when running xulrunner plugin-container, you must turn on
119 the unconfined_mozilla_plugin_transition boolean. Enabled by default.
120

136
137
138
140 The SELinux process type mozilla_plugin_t can manage files labeled with
141 the following file types. The paths listed are the default paths for
142 these file types. Note the processes UID still need to have DAC per‐
143 missions.

229 SELinux requires files to have an extended attribute to define the file
230 type.
231
232 You can see the context of a file using the -Z option to ls
233
234 Policy governs the access confined processes have to these files.
235 SELinux mozilla_plugin policy is very flexible allowing users to setup
236 their mozilla_plugin processes in as secure a method as possible.
237
238 STANDARD FILE CONTEXT
239
240 SELinux defines the file context types for the mozilla_plugin, if you
241 wanted to store files with these types in a diffent paths, you need to
242 execute the semanage command to sepecify alternate labeling and then
243 use restorecon to put the labels on disk.
244
245 semanage fcontext -a -t mozilla_plugin_tmpfs_t '/srv/mymozilla_plug‐
246 in_content(/.*)?'
247 restorecon -R -v /srv/mymozilla_plugin_content
248
249 Note: SELinux often uses regular expressions to specify labels that
250 match multiple files.
251
252 The following file types are defined for mozilla_plugin:
253
254
255
256 mozilla_plugin_config_exec_t
257
258 - Set files with the mozilla_plugin_config_exec_t type, if you want to
259 transition an executable to the mozilla_plugin_config_t domain.
260
261
262
263 mozilla_plugin_exec_t
264
265 - Set files with the mozilla_plugin_exec_t type, if you want to transi‐
266 tion an executable to the mozilla_plugin_t domain.
267
268
269
270 mozilla_plugin_rw_t
271
272 - Set files with the mozilla_plugin_rw_t type, if you want to treat the
273 files as mozilla plugin read/write content.
274
275
276
277 mozilla_plugin_tmp_t
278
279 - Set files with the mozilla_plugin_tmp_t type, if you want to store
280 mozilla plugin temporary files in the /tmp directories.
281
282
283
284 mozilla_plugin_tmpfs_t
285
286 - Set files with the mozilla_plugin_tmpfs_t type, if you want to store
287 mozilla plugin files on a tmpfs file system.
288
289
290
291 Note: File context can be temporarily modified with the chcon command.
292 If you want to permanently change the file context you need to use the
293 semanage fcontext command. This will modify the SELinux labeling data‐
294 base. You will need to use restorecon to apply the labels.
295
296
298 semanage fcontext can also be used to manipulate default file context
299 mappings.
300
301 semanage permissive can also be used to manipulate whether or not a
302 process type is permissive.
303
304 semanage module can also be used to enable/disable/install/remove pol‐
305 icy modules.
306
307 semanage boolean can also be used to manipulate the booleans
308
309
310 system-config-selinux is a GUI tool available to customize SELinux pol‐
311 icy settings.
