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 all domains to execute in fips_mode, you must turn
59 on the fips_mode boolean. Enabled by default.
60
61 setsebool -P fips_mode 1
62
63
64
65 If you want to allow system to run with NIS, you must turn on the
66 nis_enabled boolean. Disabled by default.
67
68 setsebool -P nis_enabled 1
69
70
71
72 If you want to allow regular users direct dri device access, you must
73 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
74
75 setsebool -P selinuxuser_direct_dri_enabled 1
76
77
78
79 If you want to allows clients to write to the X server shared memory
80 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
81 abled by default.
82
83 setsebool -P xserver_clients_write_xshm 1
84
85
86
88 The SELinux process type tvtime_t can manage files labeled with the
89 following file types. The paths listed are the default paths for these
90 file types. Note the processes UID still need to have DAC permissions.

96
97 /home/[^/]+/.Private(/.*)?
98 /home/[^/]+/.ecryptfs(/.*)?

129 SELinux requires files to have an extended attribute to define the file
130 type.
131
132 You can see the context of a file using the -Z option to ls
133
134 Policy governs the access confined processes have to these files.
135 SELinux tvtime policy is very flexible allowing users to setup their
136 tvtime processes in as secure a method as possible.
137
138 STANDARD FILE CONTEXT
139
140 SELinux defines the file context types for the tvtime, if you wanted to
141 store files with these types in a diffent paths, you need to execute
142 the semanage command to specify alternate labeling and then use re‐
143 storecon to put the labels on disk.
144
145 semanage fcontext -a -t tvtime_tmpfs_t '/srv/mytvtime_content(/.*)?'
146 restorecon -R -v /srv/mytvtime_content
147
148 Note: SELinux often uses regular expressions to specify labels that
149 match multiple files.
150
151 The following file types are defined for tvtime:
152
153
154
155 tvtime_exec_t
156
157 - Set files with the tvtime_exec_t type, if you want to transition an
158 executable to the tvtime_t domain.
159
160
161
162 tvtime_home_t
163
164 - Set files with the tvtime_home_t type, if you want to store tvtime
165 files in the users home directory.
166
167
168
169 tvtime_tmp_t
170
171 - Set files with the tvtime_tmp_t type, if you want to store tvtime
172 temporary files in the /tmp directories.
173
174
175
176 tvtime_tmpfs_t
177
178 - Set files with the tvtime_tmpfs_t type, if you want to store tvtime
179 files on a tmpfs file system.
180
181
182
183 Note: File context can be temporarily modified with the chcon command.
184 If you want to permanently change the file context you need to use the
185 semanage fcontext command. This will modify the SELinux labeling data‐
186 base. You will need to use restorecon to apply the labels.
187
188
190 semanage fcontext can also be used to manipulate default file context
191 mappings.
192
193 semanage permissive can also be used to manipulate whether or not a
194 process type is permissive.
195
196 semanage module can also be used to enable/disable/install/remove pol‐
197 icy modules.
198
199 semanage boolean can also be used to manipulate the booleans
200
201
202 system-config-selinux is a GUI tool available to customize SELinux pol‐
203 icy settings.
