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.

140 turn on the init_upstart boolean. Enabled by default.
141 setsebool -P init_upstart 1

147 you must turn on the nscd_use_shm boolean. Enabled by default.
148 setsebool -P nscd_use_shm 1

154 The SELinux process type ksmtuned_t can manage files labeled with the
155 following file types. The paths listed are the default paths for these
156 file types. Note the processes UID still need to have DAC permissions.

229 SELinux requires files to have an extended attribute to define the file
230 type.
231 You can see the context of a file using the -Z option to ls
233 Policy governs the access confined processes have to these files.
235 SELinux ksmtuned policy is very flexible allowing users to setup their
236 ksmtuned processes in as secure a method as possible.
237 STANDARD FILE CONTEXT
239 SELinux defines the file context types for the ksmtuned, if you wanted
241 to store files with these types in a diffent paths, you need to execute
242 the semanage command to sepecify alternate labeling and then use
243 restorecon to put the labels on disk.
244 semanage fcontext -a -t ksmtuned_var_run_t '/srv/myksmtuned_con‐
246 tent(/.*)?'
247 restorecon -R -v /srv/myksmtuned_content
248 Note: SELinux often uses regular expressions to specify labels that
250 match multiple files.
251 The following file types are defined for ksmtuned:
253 ksmtuned_exec_t
257 - Set files with the ksmtuned_exec_t type, if you want to transition an
259 executable to the ksmtuned_t domain.
260 ksmtuned_initrc_exec_t
264 - Set files with the ksmtuned_initrc_exec_t type, if you want to tran‐
266 sition an executable to the ksmtuned_initrc_t domain.
267 ksmtuned_log_t
271 - Set files with the ksmtuned_log_t type, if you want to treat the data
273 as ksmtuned log data, usually stored under the /var/log directory.
274 ksmtuned_var_run_t
278 - Set files with the ksmtuned_var_run_t type, if you want to store the
280 ksmtuned files under the /run or /var/run directory.
281 Note: File context can be temporarily modified with the chcon command.
285 If you want to permanently change the file context you need to use the
286 semanage fcontext command. This will modify the SELinux labeling data‐
287 base. You will need to use restorecon to apply the labels.
288
291 semanage fcontext can also be used to manipulate default file context
292 mappings.
293 semanage permissive can also be used to manipulate whether or not a
295 process type is permissive.
296 semanage module can also be used to enable/disable/install/remove pol‐
298 icy modules.
299 semanage boolean can also be used to manipulate the booleans
301 system-config-selinux is a GUI tool available to customize SELinux pol‐
304 icy settings.
