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.

138 SELinux requires files to have an extended attribute to define the file
139 type.
140 You can see the context of a file using the -Z option to ls
142 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 STANDARD FILE CONTEXT
148 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 semanage fcontext -a -t ksmtuned_var_run_t '/srv/myksmtuned_con‐
155 tent(/.*)?'
156 restorecon -R -v /srv/myksmtuned_content
157 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160 The following file types are defined for ksmtuned:
162 ksmtuned_exec_t
166 - Set files with the ksmtuned_exec_t type, if you want to transition an
168 executable to the ksmtuned_t domain.
169 ksmtuned_initrc_exec_t
173 - 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 ksmtuned_log_t
180 - 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 ksmtuned_unit_file_t
187 - Set files with the ksmtuned_unit_file_t type, if you want to treat
189 the files as ksmtuned unit content.
190 ksmtuned_var_run_t
194 - 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 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
207 semanage fcontext can also be used to manipulate default file context
208 mappings.
209 semanage permissive can also be used to manipulate whether or not a
211 process type is permissive.
212 semanage module can also be used to enable/disable/install/remove pol‐
214 icy modules.
215 semanage boolean can also be used to manipulate the booleans
217 system-config-selinux is a GUI tool available to customize SELinux pol‐
220 icy settings.
