6 evtchnd_selinux - Security Enhanced Linux Policy for the evtchnd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the evtchnd processes via flexible
11 mandatory access control.
12 The evtchnd processes execute with the evtchnd_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 evtchnd_t
20
24 The evtchnd_t SELinux type can be entered via the evtchnd_exec_t file
25 type.
26 The default entrypoint paths for the evtchnd_t domain are the follow‐
28 ing:
29 /usr/sbin/evtchnd
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 evtchnd policy is very flexible allowing users to setup their evtchnd
40 processes in as secure a method as possible.
41 The following process types are defined for evtchnd:
43 evtchnd_t
45 Note: semanage permissive -a evtchnd_t can be used to make the process
47 type evtchnd_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. evtchnd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run evtchnd with the tightest access possi‐
56 ble.
57 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72
76 The SELinux process type evtchnd_t can manage files labeled with the
77 following file types. The paths listed are the default paths for these
78 file types. Note the processes UID still need to have DAC permissions.

127 SELinux requires files to have an extended attribute to define the file
128 type.
129 You can see the context of a file using the -Z option to ls
131 Policy governs the access confined processes have to these files.
133 SELinux evtchnd policy is very flexible allowing users to setup their
134 evtchnd processes in as secure a method as possible.
135 STANDARD FILE CONTEXT
137 SELinux defines the file context types for the evtchnd, if you wanted
139 to store files with these types in a different paths, you need to exe‐
140 cute the semanage command to specify alternate labeling and then use
141 restorecon to put the labels on disk.
142 semanage fcontext -a -t evtchnd_exec_t '/srv/evtchnd/content(/.*)?'
144 restorecon -R -v /srv/myevtchnd_content
145 Note: SELinux often uses regular expressions to specify labels that
147 match multiple files.
148 The following file types are defined for evtchnd:
150 evtchnd_exec_t
154 - Set files with the evtchnd_exec_t type, if you want to transition an
156 executable to the evtchnd_t domain.
157 evtchnd_var_log_t
161 - Set files with the evtchnd_var_log_t type, if you want to treat the
163 data as evtchnd var log data, usually stored under the /var/log direc‐
164 tory.
165 evtchnd_var_run_t
169 - Set files with the evtchnd_var_run_t type, if you want to store the
171 evtchnd files under the /run or /var/run directory.
172 Paths:
175 /var/run/evtchnd, /var/run/evtchnd.pid
176 Note: File context can be temporarily modified with the chcon command.
179 If you want to permanently change the file context you need to use the
180 semanage fcontext command. This will modify the SELinux labeling data‐
181 base. You will need to use restorecon to apply the labels.
182
185 semanage fcontext can also be used to manipulate default file context
186 mappings.
187 semanage permissive can also be used to manipulate whether or not a
189 process type is permissive.
190 semanage module can also be used to enable/disable/install/remove pol‐
192 icy modules.
193 semanage boolean can also be used to manipulate the booleans
195 system-config-selinux is a GUI tool available to customize SELinux pol‐
198 icy settings.
