6 ksmtuned_selinux - Security Enhanced Linux Policy for the ksmtuned pro‐
7 cesses
8
10 Security-Enhanced Linux secures the ksmtuned processes via flexible
11 mandatory access control.
12 The ksmtuned processes execute with the ksmtuned_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep ksmtuned_t
20
24 The ksmtuned_t SELinux type can be entered via the ksmtuned_exec_t file
25 type.
26 The default entrypoint paths for the ksmtuned_t domain are the follow‐
28 ing:
29 /usr/sbin/ksmtuned
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 ksmtuned policy is very flexible allowing users to setup their ksmtuned
40 processes in as secure a method as possible.
41 The following process types are defined for ksmtuned:
43 ksmtuned_t
45 Note: semanage permissive -a ksmtuned_t can be used to make the process
47 type ksmtuned_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. ksm‐
54 tuned policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run ksmtuned with the tightest access
56 possible.
57 If you want to allow ksmtuned to use cifs/Samba file systems, you must
61 turn on the ksmtuned_use_cifs boolean. Disabled by default.
62 setsebool -P ksmtuned_use_cifs 1
64 If you want to allow ksmtuned to use nfs file systems, you must turn on
68 the ksmtuned_use_nfs boolean. Disabled by default.
69 setsebool -P ksmtuned_use_nfs 1
71 If you want to allow all domains to execute in fips_mode, you must turn
75 on the fips_mode boolean. Enabled by default.
76 setsebool -P fips_mode 1
78 If you want to allow system to run with NIS, you must turn on the
82 nis_enabled boolean. Disabled by default.
83 setsebool -P nis_enabled 1
85
89 The SELinux process type ksmtuned_t can manage files labeled with the
90 following file types. The paths listed are the default paths for these
91 file types. Note the processes UID still need to have DAC permissions.

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 ksmtuned policy is very flexible allowing users to setup their
160 ksmtuned processes in as secure a method as possible.
161 STANDARD FILE CONTEXT
163 SELinux defines the file context types for the ksmtuned, if you wanted
165 to store files with these types in a diffent paths, you need to execute
166 the semanage command to specify alternate labeling and then use re‐
167 storecon to put the labels on disk.
168 semanage fcontext -a -t ksmtuned_var_run_t '/srv/myksmtuned_con‐
170 tent(/.*)?'
171 restorecon -R -v /srv/myksmtuned_content
172 Note: SELinux often uses regular expressions to specify labels that
174 match multiple files.
175 The following file types are defined for ksmtuned:
177 ksmtuned_exec_t
181 - Set files with the ksmtuned_exec_t type, if you want to transition an
183 executable to the ksmtuned_t domain.
184 ksmtuned_initrc_exec_t
188 - Set files with the ksmtuned_initrc_exec_t type, if you want to tran‐
190 sition an executable to the ksmtuned_initrc_t domain.
191 ksmtuned_log_t
195 - Set files with the ksmtuned_log_t type, if you want to treat the data
197 as ksmtuned log data, usually stored under the /var/log directory.
198 ksmtuned_unit_file_t
202 - Set files with the ksmtuned_unit_file_t type, if you want to treat
204 the files as ksmtuned unit content.
205 ksmtuned_var_run_t
209 - Set files with the ksmtuned_var_run_t type, if you want to store the
211 ksmtuned files under the /run or /var/run directory.
212 Note: File context can be temporarily modified with the chcon command.
216 If you want to permanently change the file context you need to use the
217 semanage fcontext command. This will modify the SELinux labeling data‐
218 base. You will need to use restorecon to apply the labels.
219
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
