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 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. Enabled by default.
105
106       setsebool -P nscd_use_shm 1
107

MANAGED FILES

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.

FILE CONTEXTS

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

COMMANDS

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.
