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 all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type timemaster_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

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