6 ricci_modcluster_selinux - Security Enhanced Linux Policy for the
7 ricci_modcluster processes
8
10 Security-Enhanced Linux secures the ricci_modcluster processes via
11 flexible mandatory access control.
12 The ricci_modcluster processes execute with the ricci_modcluster_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 ricci_modcluster_t
20
24 The ricci_modcluster_t SELinux type can be entered via the ricci_mod‐
25 cluster_exec_t file type.
26 The default entrypoint paths for the ricci_modcluster_t domain are the
28 following:
29 /usr/libexec/modcluster
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 ricci_modcluster policy is very flexible allowing users to setup their
40 ricci_modcluster processes in as secure a method as possible.
41 The following process types are defined for ricci_modcluster:
43 ricci_modcluster_t, ricci_modclusterd_t
45 Note: semanage permissive -a ricci_modcluster_t can be used to make the
47 process type ricci_modcluster_t permissive. SELinux does not deny
48 access 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.
54 ricci_modcluster policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run ricci_modcluster with
56 the tightest access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to deny any process from ptracing or debugging any other
69 processes, you must turn on the deny_ptrace boolean. Enabled by
70 default.
71 setsebool -P deny_ptrace 1
73 If you want to allow any process to mmap any file on system with
77 attribute file_type, you must turn on the domain_can_mmap_files bool‐
78 ean. Enabled by default.
79 setsebool -P domain_can_mmap_files 1
81 If you want to allow all domains write to kmsg_device, while kernel is
85 executed with systemd.log_target=kmsg parameter, you must turn on the
86 domain_can_write_kmsg boolean. Disabled by default.
87 setsebool -P domain_can_write_kmsg 1
89 If you want to allow all domains to use other domains file descriptors,
93 you must turn on the domain_fd_use boolean. Enabled by default.
94 setsebool -P domain_fd_use 1
96 If you want to allow all domains to have the kernel load modules, you
100 must turn on the domain_kernel_load_modules boolean. Disabled by
101 default.
102 setsebool -P domain_kernel_load_modules 1
104 If you want to allow all domains to execute in fips_mode, you must turn
108 on the fips_mode boolean. Enabled by default.
109 setsebool -P fips_mode 1
111 If you want to enable reading of urandom for all domains, you must turn
115 on the global_ssp boolean. Disabled by default.
116 setsebool -P global_ssp 1
118 If you want to allow confined applications to run with kerberos, you
122 must turn on the kerberos_enabled boolean. Enabled by default.
123 setsebool -P kerberos_enabled 1
125 If you want to allow system to run with NIS, you must turn on the
129 nis_enabled boolean. Disabled by default.
130 setsebool -P nis_enabled 1
132 If you want to allow confined applications to use nscd shared memory,
136 you must turn on the nscd_use_shm boolean. Disabled by default.
137 setsebool -P nscd_use_shm 1
139
143 SELinux defines port types to represent TCP and UDP ports.
144 You can see the types associated with a port by using the following
146 command:
147 semanage port -l
149 Policy governs the access confined processes have to these ports.
152 SELinux ricci_modcluster policy is very flexible allowing users to set‐
153 up their ricci_modcluster processes in as secure a method as possible.
154 The following port types are defined for ricci_modcluster:
156 ricci_modcluster_port_t
159 Default Defined Ports:
163 tcp 16851
164 udp 16851
165
167 The SELinux process type ricci_modcluster_t can manage files labeled
168 with the following file types. The paths listed are the default paths
169 for these file types. Note the processes UID still need to have DAC
170 permissions.
171 cluster_conf_t
173 /etc/cluster(/.*)?
175 systemd_passwd_var_run_t
177 /var/run/systemd/ask-password(/.*)?
179 /var/run/systemd/ask-password-block(/.*)?
180
183 SELinux requires files to have an extended attribute to define the file
184 type.
185 You can see the context of a file using the -Z option to ls
187 Policy governs the access confined processes have to these files.
189 SELinux ricci_modcluster policy is very flexible allowing users to set‐
190 up their ricci_modcluster processes in as secure a method as possible.
191 STANDARD FILE CONTEXT
193 SELinux defines the file context types for the ricci_modcluster, if you
195 wanted to store files with these types in a diffent paths, you need to
196 execute the semanage command to sepecify alternate labeling and then
197 use restorecon to put the labels on disk.
198 semanage fcontext -a -t ricci_modclusterd_tmpfs_t '/srv/myricci_mod‐
200 cluster_content(/.*)?'
201 restorecon -R -v /srv/myricci_modcluster_content
202 Note: SELinux often uses regular expressions to specify labels that
204 match multiple files.
205 The following file types are defined for ricci_modcluster:
207 ricci_modcluster_exec_t
211 - Set files with the ricci_modcluster_exec_t type, if you want to tran‐
213 sition an executable to the ricci_modcluster_t domain.
214 ricci_modcluster_var_lib_t
218 - Set files with the ricci_modcluster_var_lib_t type, if you want to
220 store the ricci modcluster files under the /var/lib directory.
221 ricci_modcluster_var_log_t
225 - Set files with the ricci_modcluster_var_log_t type, if you want to
227 treat the data as ricci modcluster var log data, usually stored under
228 the /var/log directory.
229 ricci_modcluster_var_run_t
233 - Set files with the ricci_modcluster_var_run_t type, if you want to
235 store the ricci modcluster files under the /run or /var/run directory.
236 Paths:
239 /var/run/clumond.sock, /var/run/modclusterd.pid
240 ricci_modclusterd_exec_t
243 - Set files with the ricci_modclusterd_exec_t type, if you want to
245 transition an executable to the ricci_modclusterd_t domain.
246 ricci_modclusterd_tmpfs_t
250 - Set files with the ricci_modclusterd_tmpfs_t type, if you want to
252 store ricci modclusterd files on a tmpfs file system.
253 Note: File context can be temporarily modified with the chcon command.
257 If you want to permanently change the file context you need to use the
258 semanage fcontext command. This will modify the SELinux labeling data‐
259 base. You will need to use restorecon to apply the labels.
260
263 semanage fcontext can also be used to manipulate default file context
264 mappings.
265 semanage permissive can also be used to manipulate whether or not a
267 process type is permissive.
268 semanage module can also be used to enable/disable/install/remove pol‐
270 icy modules.
271 semanage port can also be used to manipulate the port definitions
273 semanage boolean can also be used to manipulate the booleans
275 system-config-selinux is a GUI tool available to customize SELinux pol‐
278 icy settings.
