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. Disabled by
92 default.
93
94 setsebool -P selinuxuser_direct_dri_enabled 1
95
96
97
98 If you want to allow all unconfined executables to use libraries
99 requiring text relocation that are not labeled textrel_shlib_t, you
100 must turn on the selinuxuser_execmod boolean. Disabled by default.
101
102 setsebool -P selinuxuser_execmod 1
103
104
105
106 If you want to support NFS home directories, you must turn on the
107 use_nfs_home_dirs boolean. Enabled by default.
108
109 setsebool -P use_nfs_home_dirs 1
110
111
112
113 If you want to support SAMBA home directories, you must turn on the
114 use_samba_home_dirs boolean. Disabled by default.
115
116 setsebool -P use_samba_home_dirs 1
117
118
119
120 If you want to allows clients to write to the X server shared memory
121 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
122 abled by default.
123
124 setsebool -P xserver_clients_write_xshm 1
125
126
127
129 The SELinux process type mplayer_t can manage files labeled with the
130 following file types. The paths listed are the default paths for these
131 file types. Note the processes UID still need to have DAC permissions.
132
133 cifs_t
134
135
136 nfs_t
137
138
139 pulseaudio_home_t
140
141 /root/.pulse(/.*)?
142 /root/.config/pulse(/.*)?
143 /root/.esd_auth
144 /root/.pulse-cookie
145 /home/[^/]+/.pulse(/.*)?
146 /home/[^/]+/.config/pulse(/.*)?
147 /home/[^/]+/.esd_auth
148 /home/[^/]+/.pulse-cookie
149
150 user_home_t
151
152 /home/[^/]+/.+
153
154
156 SELinux requires files to have an extended attribute to define the file
157 type.
158
159 You can see the context of a file using the -Z option to ls
160
161 Policy governs the access confined processes have to these files.
162 SELinux mplayer policy is very flexible allowing users to setup their
163 mplayer processes in as secure a method as possible.
164
165 STANDARD FILE CONTEXT
166
167 SELinux defines the file context types for the mplayer, if you wanted
168 to store files with these types in a diffent paths, you need to execute
169 the semanage command to sepecify alternate labeling and then use
170 restorecon to put the labels on disk.
171
172 semanage fcontext -a -t mplayer_tmpfs_t '/srv/mymplayer_content(/.*)?'
173 restorecon -R -v /srv/mymplayer_content
174
175 Note: SELinux often uses regular expressions to specify labels that
176 match multiple files.
177
178 The following file types are defined for mplayer:
179
180
181
182 mplayer_etc_t
183
184 - Set files with the mplayer_etc_t type, if you want to store mplayer
185 files in the /etc directories.
186
187
188
189 mplayer_exec_t
190
191 - Set files with the mplayer_exec_t type, if you want to transition an
192 executable to the mplayer_t domain.
193
194
195 Paths:
196 /usr/bin/vlc, /usr/bin/xine, /usr/bin/mplayer
197
198
199 mplayer_home_t
200
201 - Set files with the mplayer_home_t type, if you want to store mplayer
202 files in the users home directory.
203
204
205
206 mplayer_tmpfs_t
207
208 - Set files with the mplayer_tmpfs_t type, if you want to store mplayer
209 files on a tmpfs file system.
210
211
212
213 Note: File context can be temporarily modified with the chcon command.
214 If you want to permanently change the file context you need to use the
215 semanage fcontext command. This will modify the SELinux labeling data‐
216 base. You will need to use restorecon to apply the labels.
217
218
220 semanage fcontext can also be used to manipulate default file context
221 mappings.
222
223 semanage permissive can also be used to manipulate whether or not a
224 process type is permissive.
225
226 semanage module can also be used to enable/disable/install/remove pol‐
227 icy modules.
228
229 semanage boolean can also be used to manipulate the booleans
230
231
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
233 icy settings.
