NAME

6       ksm_selinux - Security Enhanced Linux Policy for the ksm processes
7

DESCRIPTION

9       Security-Enhanced  Linux  secures the ksm processes via flexible manda‐
10       tory access control.
11
12       The ksm processes execute with the ksm_t SELinux type. You can check if
13       you  have  these processes running by executing the ps command with the
14       -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep ksm_t
19

21

ENTRYPOINTS

23       The ksm_t SELinux type can be entered via the ksm_exec_t file type.
24
25       The default entrypoint paths for the ksm_t domain are the following:
26
27       /usr/libexec/ksmctl
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       ksm policy is very flexible allowing users to setup their ksm processes
37       in as secure a method as possible.
38
39       The following process types are defined for ksm:
40
41       ksmtuned_t, ksm_t
42
43       Note: semanage permissive -a ksm_t can be used to make the process type
44       ksm_t permissive. SELinux does not deny access  to  permissive  process
45       types, but the AVC (SELinux denials) messages are still generated.
46
47

BOOLEANS

49       SELinux  policy  is  customizable  based on least access required.  ksm
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run ksm with the tightest access possible.
52
53
54
55       If you want to allow all domains to execute in fips_mode, you must turn
56       on the fips_mode boolean. Enabled by default.
57
58       setsebool -P fips_mode 1

MANAGED FILES

63       The SELinux process type ksm_t can manage files labeled with  the  fol‐
64       lowing  file  types.   The paths listed are the default paths for these
65       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

109       SELinux requires files to have an extended attribute to define the file
110       type.
111
112       You can see the context of a file using the -Z option to ls
113
114       Policy  governs  the  access  confined  processes  have to these files.
115       SELinux ksm policy is very flexible allowing users to setup  their  ksm
116       processes in as secure a method as possible.
117
118       STANDARD FILE CONTEXT
119
120       SELinux  defines  the  file context types for the ksm, if you wanted to
121       store files with these types in a diffent paths, you  need  to  execute
122       the  semanage  command  to  specify alternate labeling and then use re‐
123       storecon to put the labels on disk.
124
125       semanage fcontext -a -t ksmtuned_var_run_t '/srv/myksm_content(/.*)?'
126       restorecon -R -v /srv/myksm_content
127
128       Note: SELinux often uses regular expressions  to  specify  labels  that
129       match multiple files.
130
131       The following file types are defined for ksm:
132
133
134
135       ksm_exec_t
136
137       - Set files with the ksm_exec_t type, if you want to transition an exe‐
138       cutable to the ksm_t domain.
139
140
141
142       ksm_unit_file_t
143
144       - Set files with the ksm_unit_file_t type, if you  want  to  treat  the
145       files as ksm unit content.
146
147
148
149       ksmtuned_exec_t
150
151       - Set files with the ksmtuned_exec_t type, if you want to transition an
152       executable to the ksmtuned_t domain.
153
154
155
156       ksmtuned_initrc_exec_t
157
158       - Set files with the ksmtuned_initrc_exec_t type, if you want to  tran‐
159       sition an executable to the ksmtuned_initrc_t domain.
160
161
162
163       ksmtuned_log_t
164
165       - Set files with the ksmtuned_log_t type, if you want to treat the data
166       as ksmtuned log data, usually stored under the /var/log directory.
167
168
169
170       ksmtuned_unit_file_t
171
172       - Set files with the ksmtuned_unit_file_t type, if you  want  to  treat
173       the files as ksmtuned unit content.
174
175
176
177       ksmtuned_var_run_t
178
179       -  Set files with the ksmtuned_var_run_t type, if you want to store the
180       ksmtuned files under the /run or /var/run directory.
181
182
183
184       Note: File context can be temporarily modified with the chcon  command.
185       If  you want to permanently change the file context you need to use the
186       semanage fcontext command.  This will modify the SELinux labeling data‐
187       base.  You will need to use restorecon to apply the labels.
188
189

COMMANDS

191       semanage  fcontext  can also be used to manipulate default file context
192       mappings.
193
194       semanage permissive can also be used to manipulate  whether  or  not  a
195       process type is permissive.
196
197       semanage  module can also be used to enable/disable/install/remove pol‐
198       icy modules.
199
200       semanage boolean can also be used to manipulate the booleans
201
202
203       system-config-selinux is a GUI tool available to customize SELinux pol‐
204       icy settings.
