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 allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1

68 The SELinux process type evtchnd_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

119 SELinux requires files to have an extended attribute to define the file
120 type.
121 You can see the context of a file using the -Z option to ls
123 Policy governs the access confined processes have to these files.
125 SELinux evtchnd policy is very flexible allowing users to setup their
126 evtchnd processes in as secure a method as possible.
127 STANDARD FILE CONTEXT
129 SELinux defines the file context types for the evtchnd, if you wanted
131 to store files with these types in a diffent paths, you need to execute
132 the semanage command to specify alternate labeling and then use re‐
133 storecon to put the labels on disk.
134 semanage fcontext -a -t evtchnd_var_run_t '/srv/myevtchnd_con‐
136 tent(/.*)?'
137 restorecon -R -v /srv/myevtchnd_content
138 Note: SELinux often uses regular expressions to specify labels that
140 match multiple files.
141 The following file types are defined for evtchnd:
143 evtchnd_exec_t
147 - Set files with the evtchnd_exec_t type, if you want to transition an
149 executable to the evtchnd_t domain.
150 evtchnd_var_log_t
154 - Set files with the evtchnd_var_log_t type, if you want to treat the
156 data as evtchnd var log data, usually stored under the /var/log direc‐
157 tory.
158 evtchnd_var_run_t
162 - Set files with the evtchnd_var_run_t type, if you want to store the
164 evtchnd files under the /run or /var/run directory.
165 Paths:
168 /var/run/evtchnd, /var/run/evtchnd.pid
169 Note: File context can be temporarily modified with the chcon command.
172 If you want to permanently change the file context you need to use the
173 semanage fcontext command. This will modify the SELinux labeling data‐
174 base. You will need to use restorecon to apply the labels.
175
178 semanage fcontext can also be used to manipulate default file context
179 mappings.
180 semanage permissive can also be used to manipulate whether or not a
182 process type is permissive.
183 semanage module can also be used to enable/disable/install/remove pol‐
185 icy modules.
186 semanage boolean can also be used to manipulate the booleans
188 system-config-selinux is a GUI tool available to customize SELinux pol‐
191 icy settings.
