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 execute scripts, you must
66 turn on the mcelog_exec_scripts boolean. Enabled by default.
67
68 setsebool -P mcelog_exec_scripts 1
69
70
71
72 If you want to determine whether mcelog can use all the user ttys, you
73 must turn on the mcelog_foreground boolean. Disabled by default.
74
75 setsebool -P mcelog_foreground 1
76
77
78
79 If you want to determine whether mcelog supports server mode, you must
80 turn on the mcelog_server boolean. Disabled by default.
81
82 setsebool -P mcelog_server 1
83
84
85
86 If you want to allow users to resolve user passwd entries directly from
87 ldap rather then using a sssd server, you must turn on the authlo‐
88 gin_nsswitch_use_ldap boolean. Disabled by default.
89
90 setsebool -P authlogin_nsswitch_use_ldap 1
91
92
93
94 If you want to allow all domains to execute in fips_mode, you must turn
95 on the fips_mode boolean. Enabled by default.
96
97 setsebool -P fips_mode 1
98
99
100
101 If you want to allow confined applications to run with kerberos, you
102 must turn on the kerberos_enabled boolean. Disabled by default.
103
104 setsebool -P kerberos_enabled 1
105
106
107
108 If you want to allow system to run with NIS, you must turn on the
109 nis_enabled boolean. Disabled by default.
110
111 setsebool -P nis_enabled 1
112
113
114
115 If you want to allow confined applications to use nscd shared memory,
116 you must turn on the nscd_use_shm boolean. Disabled by default.
117
118 setsebool -P nscd_use_shm 1
119
120
121
123 The SELinux process type mcelog_t can manage files labeled with the
124 following file types. The paths listed are the default paths for these
125 file types. Note the processes UID still need to have DAC permissions.

172 SELinux requires files to have an extended attribute to define the file
173 type.
174
175 You can see the context of a file using the -Z option to ls
176
177 Policy governs the access confined processes have to these files.
178 SELinux mcelog policy is very flexible allowing users to setup their
179 mcelog processes in as secure a method as possible.
180
181 STANDARD FILE CONTEXT
182
183 SELinux defines the file context types for the mcelog, if you wanted to
184 store files with these types in a diffent paths, you need to execute
185 the semanage command to sepecify alternate labeling and then use
186 restorecon to put the labels on disk.
187
188 semanage fcontext -a -t mcelog_var_run_t '/srv/mymcelog_content(/.*)?'
189 restorecon -R -v /srv/mymcelog_content
190
191 Note: SELinux often uses regular expressions to specify labels that
192 match multiple files.
193
194 The following file types are defined for mcelog:
195
196
197
198 mcelog_etc_t
199
200 - Set files with the mcelog_etc_t type, if you want to store mcelog
201 files in the /etc directories.
202
203
204
205 mcelog_exec_t
206
207 - Set files with the mcelog_exec_t type, if you want to transition an
208 executable to the mcelog_t domain.
209
210
211
212 mcelog_initrc_exec_t
213
214 - Set files with the mcelog_initrc_exec_t type, if you want to transi‐
215 tion an executable to the mcelog_initrc_t domain.
216
217
218
219 mcelog_log_t
220
221 - Set files with the mcelog_log_t type, if you want to treat the data
222 as mcelog log data, usually stored under the /var/log directory.
223
224
225
226 mcelog_var_run_t
227
228 - Set files with the mcelog_var_run_t type, if you want to store the
229 mcelog files under the /run or /var/run directory.
230
231
232
233 Note: File context can be temporarily modified with the chcon command.
234 If you want to permanently change the file context you need to use the
235 semanage fcontext command. This will modify the SELinux labeling data‐
236 base. You will need to use restorecon to apply the labels.
237
238
240 semanage fcontext can also be used to manipulate default file context
241 mappings.
242
243 semanage permissive can also be used to manipulate whether or not a
244 process type is permissive.
245
246 semanage module can also be used to enable/disable/install/remove pol‐
247 icy modules.
248
249 semanage boolean can also be used to manipulate the booleans
250
251
252 system-config-selinux is a GUI tool available to customize SELinux pol‐
253 icy settings.
