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. Disabled 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. Disabled by
96 default.
97
98 setsebool -P selinuxuser_direct_dri_enabled 1
99
100
101
102 If you want to allows clients to write to the X server shared memory
103 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
104 abled by default.
105
106 setsebool -P xserver_clients_write_xshm 1
107
108
109
111 The SELinux process type tvtime_t can manage files labeled with the
112 following file types. The paths listed are the default paths for these
113 file types. Note the processes UID still need to have DAC permissions.

118 ecryptfs_t
119
120 /home/[^/]+/.Private(/.*)?

122
123 fusefs_t

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 tvtime policy is very flexible allowing users to setup their
163 tvtime processes in as secure a method as possible.
164
165 STANDARD FILE CONTEXT
166
167 SELinux defines the file context types for the tvtime, if you wanted to
168 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 tvtime_tmpfs_t '/srv/mytvtime_content(/.*)?'
173 restorecon -R -v /srv/mytvtime_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 tvtime:
179
180
181
182 tvtime_exec_t
183
184 - Set files with the tvtime_exec_t type, if you want to transition an
185 executable to the tvtime_t domain.
186
187
188
189 tvtime_home_t
190
191 - Set files with the tvtime_home_t type, if you want to store tvtime
192 files in the users home directory.
193
194
195
196 tvtime_tmp_t
197
198 - Set files with the tvtime_tmp_t type, if you want to store tvtime
199 temporary files in the /tmp directories.
200
201
202
203 tvtime_tmpfs_t
204
205 - Set files with the tvtime_tmpfs_t type, if you want to store tvtime
206 files on a tmpfs file system.
207
208
209
210 Note: File context can be temporarily modified with the chcon command.
211 If you want to permanently change the file context you need to use the
212 semanage fcontext command. This will modify the SELinux labeling data‐
213 base. You will need to use restorecon to apply the labels.
214
215
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219
220 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222
223 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225
226 semanage boolean can also be used to manipulate the booleans
227
228
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
230 icy settings.
