6 mencoder_selinux - Security Enhanced Linux Policy for the mencoder pro‐
7 cesses
8
10 Security-Enhanced Linux secures the mencoder processes via flexible
11 mandatory access control.
12
13 The mencoder processes execute with the mencoder_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep mencoder_t
20
21
22
24 The mencoder_t SELinux type can be entered via the mencoder_exec_t file
25 type.
26
27 The default entrypoint paths for the mencoder_t domain are the follow‐
28 ing:
29
30 /usr/bin/mencoder
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 mencoder policy is very flexible allowing users to setup their mencoder
40 processes in as secure a method as possible.
41
42 The following process types are defined for mencoder:
43
44 mencoder_t
45
46 Note: semanage permissive -a mencoder_t can be used to make the process
47 type mencoder_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. men‐
54 coder policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run mencoder with the tightest access
56 possible.
57
58
59
60 If you want to deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Enabled by default.
64
65 setsebool -P deny_execmem 1
66
67
68
69 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71
72 setsebool -P fips_mode 1
73
74
75
76 If you want to determine whether mplayer can make its stack executable,
77 you must turn on the mplayer_execstack boolean. Disabled by default.
78
79 setsebool -P mplayer_execstack 1
80
81
82
83 If you want to allow all unconfined executables to use libraries
84 requiring text relocation that are not labeled textrel_shlib_t, you
85 must turn on the selinuxuser_execmod boolean. Enabled by default.
86
87 setsebool -P selinuxuser_execmod 1
88
89
90
91 If you want to support NFS home directories, you must turn on the
92 use_nfs_home_dirs boolean. Disabled by default.
93
94 setsebool -P use_nfs_home_dirs 1
95
96
97
98 If you want to support SAMBA home directories, you must turn on the
99 use_samba_home_dirs boolean. Disabled by default.
100
101 setsebool -P use_samba_home_dirs 1
102
103
104
106 The SELinux process type mencoder_t can manage files labeled with the
107 following file types. The paths listed are the default paths for these
108 file types. Note the processes UID still need to have DAC permissions.
109
110 cifs_t
111
112
113 mplayer_home_t
114
115 /home/[^/]+/.mplayer(/.*)?
116
117 nfs_t
118
119
120 user_home_t
121
122 /home/[^/]+/.+
123
124 user_tmp_t
125
126 /dev/shm/mono.*
127 /var/run/user(/.*)?
128 /tmp/.ICE-unix(/.*)?
129 /tmp/.X11-unix(/.*)?
130 /dev/shm/pulse-shm.*
131 /tmp/.X0-lock
132 /tmp/hsperfdata_root
133 /var/tmp/hsperfdata_root
134 /home/[^/]+/tmp
135 /home/[^/]+/.tmp
136 /tmp/gconfd-[^/]+
137
138
140 SELinux requires files to have an extended attribute to define the file
141 type.
142
143 You can see the context of a file using the -Z option to ls
144
145 Policy governs the access confined processes have to these files.
146 SELinux mencoder policy is very flexible allowing users to setup their
147 mencoder processes in as secure a method as possible.
148
149 The following file types are defined for mencoder:
150
151
152
153 mencoder_exec_t
154
155 - Set files with the mencoder_exec_t type, if you want to transition an
156 executable to the mencoder_t domain.
157
158
159
160 Note: File context can be temporarily modified with the chcon command.
161 If you want to permanently change the file context you need to use the
162 semanage fcontext command. This will modify the SELinux labeling data‐
163 base. You will need to use restorecon to apply the labels.
164
165
167 semanage fcontext can also be used to manipulate default file context
168 mappings.
169
170 semanage permissive can also be used to manipulate whether or not a
171 process type is permissive.
172
173 semanage module can also be used to enable/disable/install/remove pol‐
174 icy modules.
175
176 semanage boolean can also be used to manipulate the booleans
177
178
179 system-config-selinux is a GUI tool available to customize SELinux pol‐
180 icy settings.
