NAME

6       ksmtuned_selinux - Security Enhanced Linux Policy for the ksmtuned pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  ksmtuned  processes  via  flexible
11       mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep ksmtuned_t
20
21
22

ENTRYPOINTS

24       The ksmtuned_t SELinux type can be entered via the ksmtuned_exec_t file
25       type.
26
27       The default entrypoint paths for the ksmtuned_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/ksmtuned
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       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
42       The following process types are defined for ksmtuned:
43
44       ksmtuned_t
45
46       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
51

BOOLEANS

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
58
59
60       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
63       setsebool -P ksmtuned_use_cifs 1
64
65
66
67       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
70       setsebool -P ksmtuned_use_nfs 1
71
72
73
74       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
77       setsebool -P fips_mode 1
78
79
80
81       If  you  want  to  allow  system  to run with NIS, you must turn on the
82       nis_enabled boolean. Disabled by default.
83
84       setsebool -P nis_enabled 1
85
86
87

MANAGED FILES

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.

FILE CONTEXTS

138       SELinux requires files to have an extended attribute to define the file
139       type.
140
141       You can see the context of a file using the -Z option to ls
142
143       Policy  governs  the  access  confined  processes  have to these files.
144       SELinux ksmtuned policy is very flexible allowing users to setup  their
145       ksmtuned processes in as secure a method as possible.
146
147       STANDARD FILE CONTEXT
148
149       SELinux  defines the file context types for the ksmtuned, if you wanted
150       to store files with these types in a diffent paths, you need to execute
151       the  semanage  command  to  sepecify  alternate  labeling  and then use
152       restorecon to put the labels on disk.
153
154       semanage  fcontext  -a  -t   ksmtuned_var_run_t   '/srv/myksmtuned_con‐
155       tent(/.*)?'
156       restorecon -R -v /srv/myksmtuned_content
157
158       Note:  SELinux  often  uses  regular expressions to specify labels that
159       match multiple files.
160
161       The following file types are defined for ksmtuned:
162
163
164
165       ksmtuned_exec_t
166
167       - Set files with the ksmtuned_exec_t type, if you want to transition an
168       executable to the ksmtuned_t domain.
169
170
171
172       ksmtuned_initrc_exec_t
173
174       -  Set files with the ksmtuned_initrc_exec_t type, if you want to tran‐
175       sition an executable to the ksmtuned_initrc_t domain.
176
177
178
179       ksmtuned_log_t
180
181       - Set files with the ksmtuned_log_t type, if you want to treat the data
182       as ksmtuned log data, usually stored under the /var/log directory.
183
184
185
186       ksmtuned_unit_file_t
187
188       -  Set  files  with the ksmtuned_unit_file_t type, if you want to treat
189       the files as ksmtuned unit content.
190
191
192
193       ksmtuned_var_run_t
194
195       - Set files with the ksmtuned_var_run_t type, if you want to store  the
196       ksmtuned files under the /run or /var/run directory.
197
198
199
200       Note:  File context can be temporarily modified with the chcon command.
201       If you want to permanently change the file context you need to use  the
202       semanage fcontext command.  This will modify the SELinux labeling data‐
203       base.  You will need to use restorecon to apply the labels.
204
205

COMMANDS

207       semanage fcontext can also be used to manipulate default  file  context
208       mappings.
209
210       semanage  permissive  can  also  be used to manipulate whether or not a
211       process type is permissive.
212
213       semanage module can also be used to enable/disable/install/remove  pol‐
214       icy modules.
215
216       semanage boolean can also be used to manipulate the booleans
217
218
219       system-config-selinux is a GUI tool available to customize SELinux pol‐
220       icy settings.
