6 timemaster_selinux - Security Enhanced Linux Policy for the timemaster
7 processes
8
10 Security-Enhanced Linux secures the timemaster processes via flexible
11 mandatory access control.
12 The timemaster processes execute with the timemaster_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep timemaster_t
20
24 The timemaster_t SELinux type can be entered via the timemaster_exec_t
25 file type.
26 The default entrypoint paths for the timemaster_t domain are the fol‐
28 lowing:
29 /usr/sbin/timemaster
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 timemaster policy is very flexible allowing users to setup their
40 timemaster processes in as secure a method as possible.
41 The following process types are defined for timemaster:
43 timemaster_t
45 Note: semanage permissive -a timemaster_t can be used to make the
47 process type timemaster_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 timemaster policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run timemaster with the tightest
56 access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91 setsebool -P nscd_use_shm 1

97 The SELinux process type timemaster_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

151 SELinux requires files to have an extended attribute to define the file
152 type.
153 You can see the context of a file using the -Z option to ls
155 Policy governs the access confined processes have to these files.
157 SELinux timemaster policy is very flexible allowing users to setup
158 their timemaster processes in as secure a method as possible.
159 STANDARD FILE CONTEXT
161 SELinux defines the file context types for the timemaster, if you
163 wanted to store files with these types in a diffent paths, you need to
164 execute the semanage command to sepecify alternate labeling and then
165 use restorecon to put the labels on disk.
166 semanage fcontext -a -t timemaster_unit_file_t '/srv/mytimemaster_con‐
168 tent(/.*)?'
169 restorecon -R -v /srv/mytimemaster_content
170 Note: SELinux often uses regular expressions to specify labels that
172 match multiple files.
173 The following file types are defined for timemaster:
175 timemaster_exec_t
179 - Set files with the timemaster_exec_t type, if you want to transition
181 an executable to the timemaster_t domain.
182 timemaster_tmpfs_t
186 - Set files with the timemaster_tmpfs_t type, if you want to store
188 timemaster files on a tmpfs file system.
189 timemaster_unit_file_t
193 - Set files with the timemaster_unit_file_t type, if you want to treat
195 the files as timemaster unit content.
196 timemaster_var_run_t
200 - Set files with the timemaster_var_run_t type, if you want to store
202 the timemaster files under the /run or /var/run directory.
203 Note: File context can be temporarily modified with the chcon command.
207 If you want to permanently change the file context you need to use the
208 semanage fcontext command. This will modify the SELinux labeling data‐
209 base. You will need to use restorecon to apply the labels.
210
213 semanage fcontext can also be used to manipulate default file context
214 mappings.
215 semanage permissive can also be used to manipulate whether or not a
217 process type is permissive.
218 semanage module can also be used to enable/disable/install/remove pol‐
220 icy modules.
221 semanage boolean can also be used to manipulate the booleans
223 system-config-selinux is a GUI tool available to customize SELinux pol‐
226 icy settings.
