6 newrole_selinux - Security Enhanced Linux Policy for the newrole pro‐
7 cesses
8
10 Security-Enhanced Linux secures the newrole processes via flexible
11 mandatory access control.
12
13 The newrole processes execute with the newrole_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep newrole_t
20
21
22
24 The newrole_t SELinux type can be entered via the newrole_exec_t file
25 type.
26
27 The default entrypoint paths for the newrole_t domain are the follow‐
28 ing:
29
30 /usr/bin/newrole
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 newrole policy is very flexible allowing users to setup their newrole
40 processes in as secure a method as possible.
41
42 The following process types are defined for newrole:
43
44 newrole_t
45
46 Note: semanage permissive -a newrole_t can be used to make the process
47 type newrole_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. newrole
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run newrole with the tightest access possi‐
56 ble.

59
60 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‐

111
112
113

116
117 setsebool -P global_ssp 1
118
119
120
121 If you want to allow confined applications to run with kerberos, you
122 must turn on the kerberos_enabled boolean. Enabled by default.
123
124 setsebool -P kerberos_enabled 1
125
126
127
128 If you want to allow system to run with NIS, you must turn on the
129 nis_enabled boolean. Disabled by default.
130
131 setsebool -P nis_enabled 1
132
133
134
135 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
138 setsebool -P nscd_use_shm 1
139
140
141
142 If you want to enable polyinstantiated directory support, you must turn
143 on the polyinstantiation_enabled boolean. Disabled by default.
144
145 setsebool -P polyinstantiation_enabled 1
146
147
148
149 If you want to disallow programs, such as newrole, from transitioning
150 to administrative user domains, you must turn on the secure_mode bool‐
151 ean. Enabled by default.
152
153 setsebool -P secure_mode 1
154
155
156
158 The SELinux process type newrole_t can manage files labeled with the
159 following file types. The paths listed are the default paths for these
160 file types. Note the processes UID still need to have DAC permissions.

199 SELinux requires files to have an extended attribute to define the file
200 type.
201
202 You can see the context of a file using the -Z option to ls
203
204 Policy governs the access confined processes have to these files.
205 SELinux newrole policy is very flexible allowing users to setup their
206 newrole processes in as secure a method as possible.
207
208 The following file types are defined for newrole:
209
210
211
212 newrole_exec_t
213
214 - Set files with the newrole_exec_t type, if you want to transition an
215 executable to the newrole_t domain.
216
217
218
219 Note: File context can be temporarily modified with the chcon command.
220 If you want to permanently change the file context you need to use the
221 semanage fcontext command. This will modify the SELinux labeling data‐
222 base. You will need to use restorecon to apply the labels.
223
224
226 semanage fcontext can also be used to manipulate default file context
227 mappings.
228
229 semanage permissive can also be used to manipulate whether or not a
230 process type is permissive.
231
232 semanage module can also be used to enable/disable/install/remove pol‐
233 icy modules.
234
235 semanage boolean can also be used to manipulate the booleans
236
237
238 system-config-selinux is a GUI tool available to customize SELinux pol‐
239 icy settings.
