6 prelude_lml_selinux - Security Enhanced Linux Policy for the pre‐
7 lude_lml processes
8
10 Security-Enhanced Linux secures the prelude_lml processes via flexible
11 mandatory access control.
12 The prelude_lml processes execute with the prelude_lml_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 prelude_lml_t
20
24 The prelude_lml_t SELinux type can be entered via the pre‐
25 lude_lml_exec_t file type.
26 The default entrypoint paths for the prelude_lml_t domain are the fol‐
28 lowing:
29 /usr/bin/prelude-lml
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 prelude_lml policy is very flexible allowing users to setup their pre‐
40 lude_lml processes in as secure a method as possible.
41 The following process types are defined for prelude_lml:
43 prelude_lml_t
45 Note: semanage permissive -a prelude_lml_t can be used to make the
47 process type prelude_lml_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. pre‐
54 lude_lml policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run prelude_lml with the tight‐
56 est 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. Disabled 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. Disabled by default.
91 setsebool -P nscd_use_shm 1

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

158 SELinux requires files to have an extended attribute to define the file
159 type.
160 You can see the context of a file using the -Z option to ls
162 Policy governs the access confined processes have to these files.
164 SELinux prelude_lml policy is very flexible allowing users to setup
165 their prelude_lml processes in as secure a method as possible.
166 STANDARD FILE CONTEXT
168 SELinux defines the file context types for the prelude_lml, if you
170 wanted to store files with these types in a diffent paths, you need to
171 execute the semanage command to sepecify alternate labeling and then
172 use restorecon to put the labels on disk.
173 semanage fcontext -a -t prelude_lml_var_run_t '/srv/myprelude_lml_con‐
175 tent(/.*)?'
176 restorecon -R -v /srv/myprelude_lml_content
177 Note: SELinux often uses regular expressions to specify labels that
179 match multiple files.
180 The following file types are defined for prelude_lml:
182 prelude_lml_exec_t
186 - Set files with the prelude_lml_exec_t type, if you want to transition
188 an executable to the prelude_lml_t domain.
189 prelude_lml_tmp_t
193 - Set files with the prelude_lml_tmp_t type, if you want to store pre‐
195 lude lml temporary files in the /tmp directories.
196 prelude_lml_var_run_t
200 - Set files with the prelude_lml_var_run_t type, if you want to store
202 the prelude lml 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.
