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
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
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
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
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 users to resolve user passwd entries directly from
75 ldap rather then using a sssd server, you must turn on the authlo‐
76 gin_nsswitch_use_ldap boolean. Disabled by default.
77
78 setsebool -P authlogin_nsswitch_use_ldap 1
79
80
81
82 If you want to allow all domains to execute in fips_mode, you must turn
83 on the fips_mode boolean. Enabled by default.
84
85 setsebool -P fips_mode 1
86
87
88
89 If you want to allow confined applications to run with kerberos, you
90 must turn on the kerberos_enabled boolean. Enabled by default.
91
92 setsebool -P kerberos_enabled 1
93
94
95
96 If you want to allow system to run with NIS, you must turn on the
97 nis_enabled boolean. Disabled by default.
98
99 setsebool -P nis_enabled 1
100
101
102
103 If you want to allow confined applications to use nscd shared memory,
104 you must turn on the nscd_use_shm boolean. Disabled by default.
105
106 setsebool -P nscd_use_shm 1
107
108
109
111 The SELinux process type ksmtuned_t can manage files labeled with the
112 following file types. The paths listed are the default paths for these
113 file types. Note the processes UID still need to have DAC permissions.

160 SELinux requires files to have an extended attribute to define the file
161 type.
162
163 You can see the context of a file using the -Z option to ls
164
165 Policy governs the access confined processes have to these files.
166 SELinux ksmtuned policy is very flexible allowing users to setup their
167 ksmtuned processes in as secure a method as possible.
168
169 STANDARD FILE CONTEXT
170
171 SELinux defines the file context types for the ksmtuned, if you wanted
172 to store files with these types in a diffent paths, you need to execute
173 the semanage command to sepecify alternate labeling and then use
174 restorecon to put the labels on disk.
175
176 semanage fcontext -a -t ksmtuned_var_run_t '/srv/myksmtuned_con‐
177 tent(/.*)?'
178 restorecon -R -v /srv/myksmtuned_content
179
180 Note: SELinux often uses regular expressions to specify labels that
181 match multiple files.
182
183 The following file types are defined for ksmtuned:
184
185
186
187 ksmtuned_exec_t
188
189 - Set files with the ksmtuned_exec_t type, if you want to transition an
190 executable to the ksmtuned_t domain.
191
192
193
194 ksmtuned_initrc_exec_t
195
196 - Set files with the ksmtuned_initrc_exec_t type, if you want to tran‐
197 sition an executable to the ksmtuned_initrc_t domain.
198
199
200
201 ksmtuned_log_t
202
203 - Set files with the ksmtuned_log_t type, if you want to treat the data
204 as ksmtuned log data, usually stored under the /var/log directory.
205
206
207
208 ksmtuned_unit_file_t
209
210 - Set files with the ksmtuned_unit_file_t type, if you want to treat
211 the files as ksmtuned unit content.
212
213
214
215 ksmtuned_var_run_t
216
217 - Set files with the ksmtuned_var_run_t type, if you want to store the
218 ksmtuned files under the /run or /var/run directory.
219
220
221
222 Note: File context can be temporarily modified with the chcon command.
223 If you want to permanently change the file context you need to use the
224 semanage fcontext command. This will modify the SELinux labeling data‐
225 base. You will need to use restorecon to apply the labels.
226
227
229 semanage fcontext can also be used to manipulate default file context
230 mappings.
231
232 semanage permissive can also be used to manipulate whether or not a
233 process type is permissive.
234
235 semanage module can also be used to enable/disable/install/remove pol‐
236 icy modules.
237
238 semanage boolean can also be used to manipulate the booleans
239
240
241 system-config-selinux is a GUI tool available to customize SELinux pol‐
242 icy settings.
