6 tvtime_selinux - Security Enhanced Linux Policy for the tvtime pro‐
7 cesses
8
10 Security-Enhanced Linux secures the tvtime processes via flexible
11 mandatory access control.
12
13 The tvtime processes execute with the tvtime_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 tvtime_t
20
21
22
24 The tvtime_t SELinux type can be entered via the tvtime_exec_t file
25 type.
26
27 The default entrypoint paths for the tvtime_t domain are the following:
28
29 /usr/bin/tvtime
30
32 SELinux defines process types (domains) for each process running on the
33 system
34
35 You can see the context of a process using the -Z option to ps
36
37 Policy governs the access confined processes have to files. SELinux
38 tvtime policy is very flexible allowing users to setup their tvtime
39 processes in as secure a method as possible.
40
41 The following process types are defined for tvtime:
42
43 tvtime_t
44
45 Note: semanage permissive -a tvtime_t can be used to make the process
46 type tvtime_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
50
52 SELinux policy is customizable based on least access required. tvtime
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run tvtime with the tightest access possible.
55
56
57
58 If you want to allow users to resolve user passwd entries directly from
59 ldap rather then using a sssd server, you must turn on the authlo‐
60 gin_nsswitch_use_ldap boolean. Disabled by default.
61
62 setsebool -P authlogin_nsswitch_use_ldap 1
63
64
65
66 If you want to allow all domains to execute in fips_mode, you must turn
67 on the fips_mode boolean. Enabled by default.
68
69 setsebool -P fips_mode 1
70
71
72
73 If you want to allow confined applications to run with kerberos, you
74 must turn on the kerberos_enabled boolean. Enabled by default.
75
76 setsebool -P kerberos_enabled 1
77
78
79
80 If you want to allow system to run with NIS, you must turn on the
81 nis_enabled boolean. Disabled by default.
82
83 setsebool -P nis_enabled 1
84
85
86
87 If you want to allow confined applications to use nscd shared memory,
88 you must turn on the nscd_use_shm boolean. Disabled by default.
89
90 setsebool -P nscd_use_shm 1
91
92
93
94 If you want to allow regular users direct dri device access, you must
95 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
96
97 setsebool -P selinuxuser_direct_dri_enabled 1
98
99
100
101 If you want to allows clients to write to the X server shared memory
102 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
103 abled by default.
104
105 setsebool -P xserver_clients_write_xshm 1
106
107
108
110 The SELinux process type tvtime_t can manage files labeled with the
111 following file types. The paths listed are the default paths for these
112 file types. Note the processes UID still need to have DAC permissions.
113
114 cifs_t
115
116
117 ecryptfs_t
118
119 /home/[^/]+/.Private(/.*)?
120 /home/[^/]+/.ecryptfs(/.*)?
121
122 fusefs_t
123
124 /var/run/user/[^/]*/gvfs
125
126 nfs_t
127
128
129 tvtime_home_t

155 SELinux requires files to have an extended attribute to define the file
156 type.
157
158 You can see the context of a file using the -Z option to ls
159
160 Policy governs the access confined processes have to these files.
161 SELinux tvtime policy is very flexible allowing users to setup their
162 tvtime processes in as secure a method as possible.
163
164 STANDARD FILE CONTEXT
165
166 SELinux defines the file context types for the tvtime, if you wanted to
167 store files with these types in a diffent paths, you need to execute
168 the semanage command to sepecify alternate labeling and then use
169 restorecon to put the labels on disk.
170
171 semanage fcontext -a -t tvtime_tmpfs_t '/srv/mytvtime_content(/.*)?'
172 restorecon -R -v /srv/mytvtime_content
173
174 Note: SELinux often uses regular expressions to specify labels that
175 match multiple files.
176
177 The following file types are defined for tvtime:
178
179
180
181 tvtime_exec_t
182
183 - Set files with the tvtime_exec_t type, if you want to transition an
184 executable to the tvtime_t domain.
185
186
187
188 tvtime_home_t
189
190 - Set files with the tvtime_home_t type, if you want to store tvtime
191 files in the users home directory.
192
193
194
195 tvtime_tmp_t
196
197 - Set files with the tvtime_tmp_t type, if you want to store tvtime
198 temporary files in the /tmp directories.
199
200
201
202 tvtime_tmpfs_t
203
204 - Set files with the tvtime_tmpfs_t type, if you want to store tvtime
205 files on a tmpfs file system.
206
207
208
209 Note: File context can be temporarily modified with the chcon command.
210 If you want to permanently change the file context you need to use the
211 semanage fcontext command. This will modify the SELinux labeling data‐
212 base. You will need to use restorecon to apply the labels.
213
214
216 semanage fcontext can also be used to manipulate default file context
217 mappings.
218
219 semanage permissive can also be used to manipulate whether or not a
220 process type is permissive.
221
222 semanage module can also be used to enable/disable/install/remove pol‐
223 icy modules.
224
225 semanage boolean can also be used to manipulate the booleans
226
227
228 system-config-selinux is a GUI tool available to customize SELinux pol‐
229 icy settings.
