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

146 /home/[^/]+/.fonts.cache-.*

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