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 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 For example:
18 ps -eZ | grep mcelog_t
20
24 The mcelog_t SELinux type can be entered via the mcelog_exec_t file
25 type.
26 The default entrypoint paths for the mcelog_t domain are the following:
28 /usr/sbin/mcelog
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 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 The following process types are defined for mcelog:
42 mcelog_t
44 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
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 If you want to determine whether mcelog supports client mode, you must
59 turn on the mcelog_client boolean. Disabled by default.
60 setsebool -P mcelog_client 1
62 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 setsebool -P mcelog_foreground 1
69 If you want to allow all domains to execute in fips_mode, you must turn
73 on the fips_mode boolean. Enabled by default.
74 setsebool -P fips_mode 1
76 If you want to allow system to run with NIS, you must turn on the
80 nis_enabled boolean. Disabled by default.
81 setsebool -P nis_enabled 1
83
87 The SELinux process type mcelog_t can manage files labeled with the
88 following file types. The paths listed are the default paths for these
89 file types. Note the processes UID still need to have DAC permissions.

136 SELinux requires files to have an extended attribute to define the file
137 type.
138 You can see the context of a file using the -Z option to ls
140 Policy governs the access confined processes have to these files.
142 SELinux mcelog policy is very flexible allowing users to setup their
143 mcelog processes in as secure a method as possible.
144 STANDARD FILE CONTEXT
146 SELinux defines the file context types for the mcelog, if you wanted to
148 store files with these types in a diffent paths, you need to execute
149 the semanage command to sepecify alternate labeling and then use
150 restorecon to put the labels on disk.
151 semanage fcontext -a -t mcelog_var_run_t '/srv/mymcelog_content(/.*)?'
153 restorecon -R -v /srv/mymcelog_content
154 Note: SELinux often uses regular expressions to specify labels that
156 match multiple files.
157 The following file types are defined for mcelog:
159 mcelog_etc_t
163 - Set files with the mcelog_etc_t type, if you want to store mcelog
165 files in the /etc directories.
166 mcelog_exec_t
170 - Set files with the mcelog_exec_t type, if you want to transition an
172 executable to the mcelog_t domain.
173 mcelog_initrc_exec_t
177 - Set files with the mcelog_initrc_exec_t type, if you want to transi‐
179 tion an executable to the mcelog_initrc_t domain.
180 mcelog_log_t
184 - Set files with the mcelog_log_t type, if you want to treat the data
186 as mcelog log data, usually stored under the /var/log directory.
187 mcelog_var_run_t
191 - Set files with the mcelog_var_run_t type, if you want to store the
193 mcelog files under the /run or /var/run directory.
194 Note: File context can be temporarily modified with the chcon command.
198 If you want to permanently change the file context you need to use the
199 semanage fcontext command. This will modify the SELinux labeling data‐
200 base. You will need to use restorecon to apply the labels.
201
204 semanage fcontext can also be used to manipulate default file context
205 mappings.
206 semanage permissive can also be used to manipulate whether or not a
208 process type is permissive.
209 semanage module can also be used to enable/disable/install/remove pol‐
211 icy modules.
212 semanage boolean can also be used to manipulate the booleans
214 system-config-selinux is a GUI tool available to customize SELinux pol‐
217 icy settings.
