NAME

6       mplayer_selinux  -  Security Enhanced Linux Policy for the mplayer pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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 allow users to resolve user passwd entries directly from
68       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
69       gin_nsswitch_use_ldap boolean. Disabled by default.
70
71       setsebool -P authlogin_nsswitch_use_ldap 1
72
73
74
75       If you want to deny user domains applications to map a memory region as
76       both executable and writable, this  is  dangerous  and  the  executable
77       should be reported in bugzilla, you must turn on the deny_execmem bool‐
78       ean. Enabled by default.
79
80       setsebool -P deny_execmem 1
81
82
83
84       If you want to allow all domains to execute in fips_mode, you must turn
85       on the fips_mode boolean. Enabled by default.
86
87       setsebool -P fips_mode 1
88
89
90
91       If  you  want  to allow confined applications to run with kerberos, you
92       must turn on the kerberos_enabled boolean. Enabled by default.
93
94       setsebool -P kerberos_enabled 1
95
96
97
98       If you want to allow system to run with  NIS,  you  must  turn  on  the
99       nis_enabled boolean. Disabled by default.
100
101       setsebool -P nis_enabled 1
102
103
104
105       If  you  want to allow confined applications to use nscd shared memory,
106       you must turn on the nscd_use_shm boolean. Disabled by default.
107
108       setsebool -P nscd_use_shm 1
109
110
111
112       If you want to allow regular users direct dri device access,  you  must
113       turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
114
115       setsebool -P selinuxuser_direct_dri_enabled 1
116
117
118
119       If  you  want  to  allow  all  unconfined  executables to use libraries
120       requiring text relocation that are  not  labeled  textrel_shlib_t,  you
121       must turn on the selinuxuser_execmod boolean. Enabled by default.
122
123       setsebool -P selinuxuser_execmod 1
124
125
126
127       If  you  want  to  support  NFS  home directories, you must turn on the
128       use_nfs_home_dirs boolean. Disabled by default.
129
130       setsebool -P use_nfs_home_dirs 1
131
132
133
134       If you want to support SAMBA home directories, you  must  turn  on  the
135       use_samba_home_dirs boolean. Disabled by default.
136
137       setsebool -P use_samba_home_dirs 1
138
139
140
141       If  you  want  to allows clients to write to the X server shared memory
142       segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
143       abled by default.
144
145       setsebool -P xserver_clients_write_xshm 1
146
147
148

MANAGED FILES

150       The  SELinux  process  type mplayer_t can manage files labeled with the
151       following file types.  The paths listed are the default paths for these
152       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

212       SELinux requires files to have an extended attribute to define the file
213       type.
214
215       You can see the context of a file using the -Z option to ls
216
217       Policy governs the access  confined  processes  have  to  these  files.
218       SELinux  mplayer  policy is very flexible allowing users to setup their
219       mplayer processes in as secure a method as possible.
220
221       STANDARD FILE CONTEXT
222
223       SELinux defines the file context types for the mplayer, if  you  wanted
224       to store files with these types in a diffent paths, you need to execute
225       the semanage command  to  sepecify  alternate  labeling  and  then  use
226       restorecon to put the labels on disk.
227
228       semanage fcontext -a -t mplayer_tmpfs_t '/srv/mymplayer_content(/.*)?'
229       restorecon -R -v /srv/mymplayer_content
230
231       Note:  SELinux  often  uses  regular expressions to specify labels that
232       match multiple files.
233
234       The following file types are defined for mplayer:
235
236
237
238       mplayer_etc_t
239
240       - Set files with the mplayer_etc_t type, if you want to  store  mplayer
241       files in the /etc directories.
242
243
244
245       mplayer_exec_t
246
247       -  Set files with the mplayer_exec_t type, if you want to transition an
248       executable to the mplayer_t domain.
249
250
251       Paths:
252            /usr/bin/vlc, /usr/bin/xine, /usr/bin/mplayer
253
254
255       mplayer_home_t
256
257       - Set files with the mplayer_home_t type, if you want to store  mplayer
258       files in the users home directory.
259
260
261
262       mplayer_tmpfs_t
263
264       - Set files with the mplayer_tmpfs_t type, if you want to store mplayer
265       files on a tmpfs file system.
266
267
268
269       Note: File context can be temporarily modified with the chcon  command.
270       If  you want to permanently change the file context you need to use the
271       semanage fcontext command.  This will modify the SELinux labeling data‐
272       base.  You will need to use restorecon to apply the labels.
273
274

COMMANDS

276       semanage  fcontext  can also be used to manipulate default file context
277       mappings.
278
279       semanage permissive can also be used to manipulate  whether  or  not  a
280       process type is permissive.
281
282       semanage  module can also be used to enable/disable/install/remove pol‐
283       icy modules.
284
285       semanage boolean can also be used to manipulate the booleans
286
287
288       system-config-selinux is a GUI tool available to customize SELinux pol‐
289       icy settings.
