6 mcelog_selinux - Security Enhanced Linux Policy for the mcelog pro‐
7 cesses
8
10 Security-Enhanced Linux secures the mcelog processes via flexible
11 mandatory access control.
12
13 The mcelog processes execute with the mcelog_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep mcelog_t
20
21
22
24 The mcelog_t SELinux type can be entered via the mcelog_exec_t file
25 type.
26
27 The default entrypoint paths for the mcelog_t domain are the following:
28
29 /usr/sbin/mcelog
30
32 SELinux defines process types (domains) for each process running on the
33 system
34
35 You can see the context of a process using the -Z option to ps
36
37 Policy governs the access confined processes have to files. SELinux
38 mcelog policy is very flexible allowing users to setup their mcelog
39 processes in as secure a method as possible.
40
41 The following process types are defined for mcelog:
42
43 mcelog_t
44
45 Note: semanage permissive -a mcelog_t can be used to make the process
46 type mcelog_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
50
52 SELinux policy is customizable based on least access required. mcelog
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run mcelog with the tightest access possible.
55
56
57
58 If you want to determine whether mcelog supports client mode, you must
59 turn on the mcelog_client boolean. Disabled by default.
60
61 setsebool -P mcelog_client 1
62
63
64
65 If you want to determine whether mcelog can use all the user ttys, you
66 must turn on the mcelog_foreground boolean. Disabled by default.
67
68 setsebool -P mcelog_foreground 1
69
70
71
72 If you want to dontaudit all daemons scheduling requests (setsched,
73 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
74 Enabled by default.
75
76 setsebool -P daemons_dontaudit_scheduling 1
77
78
79
80 If you want to allow all domains to execute in fips_mode, you must turn
81 on the fips_mode boolean. Enabled by default.
82
83 setsebool -P fips_mode 1
84
85
86
87 If you want to allow system to run with NIS, you must turn on the
88 nis_enabled boolean. Disabled by default.
89
90 setsebool -P nis_enabled 1
91
92
93
95 The SELinux process type mcelog_t can manage files labeled with the
96 following file types. The paths listed are the default paths for these
97 file types. Note the processes UID still need to have DAC permissions.

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