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 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 For example:
18 ps -eZ | grep systemd_coredump_t
20
24 The systemd_coredump_t SELinux type can be entered via the sys‐
25 temd_coredump_exec_t file type.
26 The default entrypoint paths for the systemd_coredump_t domain are the
28 following:
29 /bin/systemd-coredump, /usr/lib/systemd/systemd-coredump
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 systemd_coredump policy is very flexible allowing users to setup their
40 systemd_coredump processes in as secure a method as possible.
41 The following process types are defined for systemd_coredump:
43 systemd_coredump_t
45 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
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 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 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1

83 The SELinux process type systemd_coredump_t can manage files labeled
84 with the following file types. The paths listed are the default paths
85 for these file types. Note the processes UID still need to have DAC
86 permissions.

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