6 mplayer_selinux - Security Enhanced Linux Policy for the mplayer pro‐
7 cesses
8
10 Security-Enhanced Linux secures the mplayer processes via flexible
11 mandatory access control.
12
13 The mplayer processes execute with the mplayer_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep mplayer_t
20
21
22
24 The mplayer_t SELinux type can be entered via the mplayer_exec_t file
25 type.
26
27 The default entrypoint paths for the mplayer_t domain are the follow‐
28 ing:
29
30 /usr/bin/vlc, /usr/bin/xine, /usr/bin/mplayer
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 mplayer policy is very flexible allowing users to setup their mplayer
40 processes in as secure a method as possible.
41
42 The following process types are defined for mplayer:
43
44 mplayer_t
45
46 Note: semanage permissive -a mplayer_t can be used to make the process
47 type mplayer_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. mplayer
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run mplayer with the tightest access possi‐
56 ble.
57
58
59
60 If you want to determine whether mplayer can make its stack executable,
61 you must turn on the mplayer_execstack boolean. Disabled by default.
62
63 setsebool -P mplayer_execstack 1
64
65
66
67 If you want to deny user domains applications to map a memory region as
68 both executable and writable, this is dangerous and the executable
69 should be reported in bugzilla, you must turn on the deny_execmem bool‐
70 ean. Enabled by default.
71
72 setsebool -P deny_execmem 1
73
74
75
76 If you want to allow all domains to execute in fips_mode, you must turn
77 on the fips_mode boolean. Enabled by default.
78
79 setsebool -P fips_mode 1
80
81
82
83 If you want to allow system to run with NIS, you must turn on the
84 nis_enabled boolean. Disabled by default.
85
86 setsebool -P nis_enabled 1
87
88
89
90 If you want to allow regular users direct dri device access, you must
91 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
92
93 setsebool -P selinuxuser_direct_dri_enabled 1
94
95
96
97 If you want to allow all unconfined executables to use libraries re‐
98 quiring text relocation that are not labeled textrel_shlib_t, you must
99 turn on the selinuxuser_execmod boolean. Enabled by default.
100
101 setsebool -P selinuxuser_execmod 1
102
103
104
105 If you want to support NFS home directories, you must turn on the
106 use_nfs_home_dirs boolean. Disabled by default.
107
108 setsebool -P use_nfs_home_dirs 1
109
110
111
112 If you want to support SAMBA home directories, you must turn on the
113 use_samba_home_dirs boolean. Disabled by default.
114
115 setsebool -P use_samba_home_dirs 1
116
117
118
119 If you want to allows clients to write to the X server shared memory
120 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
121 abled by default.
122
123 setsebool -P xserver_clients_write_xshm 1
124
125
126
128 The SELinux process type mplayer_t can manage files labeled with the
129 following file types. The paths listed are the default paths for these
130 file types. Note the processes UID still need to have DAC permissions.

169 SELinux requires files to have an extended attribute to define the file
170 type.
171
172 You can see the context of a file using the -Z option to ls
173
174 Policy governs the access confined processes have to these files.
175 SELinux mplayer policy is very flexible allowing users to setup their
176 mplayer processes in as secure a method as possible.
177
178 STANDARD FILE CONTEXT
179
180 SELinux defines the file context types for the mplayer, if you wanted
181 to store files with these types in a diffent paths, you need to execute
182 the semanage command to specify alternate labeling and then use re‐
183 storecon to put the labels on disk.
184
185 semanage fcontext -a -t mplayer_tmpfs_t '/srv/mymplayer_content(/.*)?'
186 restorecon -R -v /srv/mymplayer_content
187
188 Note: SELinux often uses regular expressions to specify labels that
189 match multiple files.
190
191 The following file types are defined for mplayer:
192
193
194
195 mplayer_etc_t
196
197 - Set files with the mplayer_etc_t type, if you want to store mplayer
198 files in the /etc directories.
199
200
201
202 mplayer_exec_t
203
204 - Set files with the mplayer_exec_t type, if you want to transition an
205 executable to the mplayer_t domain.
206
207
208 Paths:
209 /usr/bin/vlc, /usr/bin/xine, /usr/bin/mplayer
210
211
212 mplayer_home_t
213
214 - Set files with the mplayer_home_t type, if you want to store mplayer
215 files in the users home directory.
216
217
218
219 mplayer_tmpfs_t
220
221 - Set files with the mplayer_tmpfs_t type, if you want to store mplayer
222 files on a tmpfs file system.
223
224
225
226 Note: File context can be temporarily modified with the chcon command.
227 If you want to permanently change the file context you need to use the
228 semanage fcontext command. This will modify the SELinux labeling data‐
229 base. You will need to use restorecon to apply the labels.
230
231
233 semanage fcontext can also be used to manipulate default file context
234 mappings.
235
236 semanage permissive can also be used to manipulate whether or not a
237 process type is permissive.
238
239 semanage module can also be used to enable/disable/install/remove pol‐
240 icy modules.
241
242 semanage boolean can also be used to manipulate the booleans
243
244
245 system-config-selinux is a GUI tool available to customize SELinux pol‐
246 icy settings.
