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 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 For example:
18 ps -eZ | grep tvtime_t
20
24 The tvtime_t SELinux type can be entered via the tvtime_exec_t file
25 type.
26 The default entrypoint paths for the tvtime_t domain are the following:
28 /usr/bin/tvtime
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 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 The following process types are defined for tvtime:
42 tvtime_t
44 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
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 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 setsebool -P authlogin_nsswitch_use_ldap 1
63 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 setsebool -P fips_mode 1
70 If you want to allow confined applications to run with kerberos, you
74 must turn on the kerberos_enabled boolean. Enabled by default.
75 setsebool -P kerberos_enabled 1
77 If you want to allow system to run with NIS, you must turn on the
81 nis_enabled boolean. Disabled by default.
82 setsebool -P nis_enabled 1
84 If you want to allow confined applications to use nscd shared memory,
88 you must turn on the nscd_use_shm boolean. Enabled by default.
89 setsebool -P nscd_use_shm 1
91 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 setsebool -P selinuxuser_direct_dri_enabled 1
98 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 setsebool -P xserver_clients_write_xshm 1
106
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 cifs_t
115 ecryptfs_t
118 /home/[^/]+/.Private(/.*)?
120 /home/[^/]+/.ecryptfs(/.*)?
121 fusefs_t
123 /var/run/user/[^/]*/gvfs
125 nfs_t
127 tvtime_home_t
130 /home/[^/]+/.tvtime(/.*)?
132 tvtime_tmp_t
134 tvtime_tmpfs_t
137 user_fonts_cache_t
140 /root/.fontconfig(/.*)?
142 /root/.fonts/auto(/.*)?
143 /root/.fonts.cache-.*
144 /home/[^/]+/.fontconfig(/.*)?
145 /home/[^/]+/.fonts/auto(/.*)?
146 /home/[^/]+/.fonts.cache-.*
147 xserver_tmpfs_t

153 SELinux requires files to have an extended attribute to define the file
154 type.
155 You can see the context of a file using the -Z option to ls
157 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 STANDARD FILE CONTEXT
163 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 semanage fcontext -a -t tvtime_tmpfs_t '/srv/mytvtime_content(/.*)?'
170 restorecon -R -v /srv/mytvtime_content
171 Note: SELinux often uses regular expressions to specify labels that
173 match multiple files.
174 The following file types are defined for tvtime:
176 tvtime_exec_t
180 - Set files with the tvtime_exec_t type, if you want to transition an
182 executable to the tvtime_t domain.
183 tvtime_home_t
187 - Set files with the tvtime_home_t type, if you want to store tvtime
189 files in the users home directory.
190 tvtime_tmp_t
194 - Set files with the tvtime_tmp_t type, if you want to store tvtime
196 temporary files in the /tmp directories.
197 tvtime_tmpfs_t
201 - Set files with the tvtime_tmpfs_t type, if you want to store tvtime
203 files on a tmpfs file system.
204 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
214 semanage fcontext can also be used to manipulate default file context
215 mappings.
216 semanage permissive can also be used to manipulate whether or not a
218 process type is permissive.
219 semanage module can also be used to enable/disable/install/remove pol‐
221 icy modules.
222 semanage boolean can also be used to manipulate the booleans
224 system-config-selinux is a GUI tool available to customize SELinux pol‐
227 icy settings.
