6 systemd_coredump_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_coredump processes
8
10 Security-Enhanced Linux secures the systemd_coredump processes via
11 flexible mandatory access control.
12
13 The systemd_coredump processes execute with the systemd_coredump_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep systemd_coredump_t
20
21
22
24 The systemd_coredump_t SELinux type can be entered via the sys‐
25 temd_coredump_exec_t file type.
26
27 The default entrypoint paths for the systemd_coredump_t domain are the
28 following:
29
30 /bin/systemd-coredump, /usr/lib/systemd/systemd-coredump
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 systemd_coredump policy is very flexible allowing users to setup their
40 systemd_coredump processes in as secure a method as possible.
41
42 The following process types are defined for systemd_coredump:
43
44 systemd_coredump_t
45
46 Note: semanage permissive -a systemd_coredump_t can be used to make the
47 process type systemd_coredump_t permissive. SELinux does not deny ac‐
48 cess to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
51
53 SELinux policy is customizable based on least access required. sys‐
54 temd_coredump policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run systemd_coredump with
56 the tightest access possible.
57
58
59
60 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
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type systemd_coredump_t can manage files labeled
76 with the following file types. The paths listed are the default paths
77 for these file types. Note the processes UID still need to have DAC
78 permissions.

132 SELinux requires files to have an extended attribute to define the file
133 type.
134
135 You can see the context of a file using the -Z option to ls
136
137 Policy governs the access confined processes have to these files.
138 SELinux systemd_coredump policy is very flexible allowing users to
139 setup their systemd_coredump processes in as secure a method as possi‐
140 ble.
141
142 STANDARD FILE CONTEXT
143
144 SELinux defines the file context types for the systemd_coredump, if you
145 wanted to store files with these types in a diffent paths, you need to
146 execute the semanage command to specify alternate labeling and then use
147 restorecon to put the labels on disk.
148
149 semanage fcontext -a -t systemd_coredump_var_lib_t '/srv/mysys‐
150 temd_coredump_content(/.*)?'
151 restorecon -R -v /srv/mysystemd_coredump_content
152
153 Note: SELinux often uses regular expressions to specify labels that
154 match multiple files.
155
156 The following file types are defined for systemd_coredump:
157
158
159
160 systemd_coredump_exec_t
161
162 - Set files with the systemd_coredump_exec_t type, if you want to tran‐
163 sition an executable to the systemd_coredump_t domain.
164
165
166 Paths:
167 /bin/systemd-coredump, /usr/lib/systemd/systemd-coredump
168
169
170 systemd_coredump_tmpfs_t
171
172 - Set files with the systemd_coredump_tmpfs_t type, if you want to
173 store systemd coredump files on a tmpfs file system.
174
175
176
177 systemd_coredump_var_lib_t
178
179 - Set files with the systemd_coredump_var_lib_t type, if you want to
180 store the systemd coredump files under the /var/lib directory.
181
182
183
184 Note: File context can be temporarily modified with the chcon command.
185 If you want to permanently change the file context you need to use the
186 semanage fcontext command. This will modify the SELinux labeling data‐
187 base. You will need to use restorecon to apply the labels.
188
189
191 semanage fcontext can also be used to manipulate default file context
192 mappings.
193
194 semanage permissive can also be used to manipulate whether or not a
195 process type is permissive.
196
197 semanage module can also be used to enable/disable/install/remove pol‐
198 icy modules.
199
200 semanage boolean can also be used to manipulate the booleans
201
202
203 system-config-selinux is a GUI tool available to customize SELinux pol‐
204 icy settings.
