6 ipa_helper_selinux - Security Enhanced Linux Policy for the ipa_helper
7 processes
8
10 Security-Enhanced Linux secures the ipa_helper processes via flexible
11 mandatory access control.
12
13 The ipa_helper processes execute with the ipa_helper_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep ipa_helper_t
20
21
22
24 The ipa_helper_t SELinux type can be entered via the ipa_helper_exec_t
25 file type.
26
27 The default entrypoint paths for the ipa_helper_t domain are the fol‐
28 lowing:
29
30 /usr/libexec/ipa/com.redhat.idm.trust-fetch-domains,
31 /usr/libexec/ipa/oddjob/org.freeipa.server.conncheck,
32 /usr/libexec/ipa/oddjob/com.redhat.idm.trust-fetch-domains
33
35 SELinux defines process types (domains) for each process running on the
36 system
37
38 You can see the context of a process using the -Z option to ps
39
40 Policy governs the access confined processes have to files. SELinux
41 ipa_helper policy is very flexible allowing users to setup their
42 ipa_helper processes in as secure a method as possible.
43
44 The following process types are defined for ipa_helper:
45
46 ipa_helper_t
47
48 Note: semanage permissive -a ipa_helper_t can be used to make the
49 process type ipa_helper_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
53
55 SELinux policy is customizable based on least access required.
56 ipa_helper policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run ipa_helper with the tightest
58 access possible.
59
60
61
62 If you want to allow users to resolve user passwd entries directly from
63 ldap rather then using a sssd server, you must turn on the authlo‐
64 gin_nsswitch_use_ldap boolean. Disabled by default.

87 ean. Enabled by default.

94 executed with systemd.log_target=kmsg parameter, you must turn on the
95 domain_can_write_kmsg boolean. Disabled by default.
96
97 setsebool -P domain_can_write_kmsg 1
98
99
100
101 If you want to allow all domains to use other domains file descriptors,
102 you must turn on the domain_fd_use boolean. Enabled by default.
103
104 setsebool -P domain_fd_use 1
105
106
107
108 If you want to allow all domains to have the kernel load modules, you
109 must turn on the domain_kernel_load_modules boolean. Disabled by
110 default.
111
112 setsebool -P domain_kernel_load_modules 1
113
114
115
116 If you want to allow all domains to execute in fips_mode, you must turn
117 on the fips_mode boolean. Enabled by default.
118
119 setsebool -P fips_mode 1
120
121
122
123 If you want to enable reading of urandom for all domains, you must turn
124 on the global_ssp boolean. Disabled by default.
125
126 setsebool -P global_ssp 1
127
128
129
130 If you want to allow httpd processes to run IPA helper, you must turn
131 on the httpd_run_ipa boolean. Disabled by default.
132
133 setsebool -P httpd_run_ipa 1
134
135
136
137 If you want to allow confined applications to run with kerberos, you
138 must turn on the kerberos_enabled boolean. Enabled by default.
139
140 setsebool -P kerberos_enabled 1
141
142
143
144 If you want to allow system to run with NIS, you must turn on the
145 nis_enabled boolean. Disabled by default.

152 you must turn on the nscd_use_shm boolean. Disabled by default.
153
154 setsebool -P nscd_use_shm 1
155
156
157
159 The SELinux process type ipa_helper_t can manage files labeled with the
160 following file types. The paths listed are the default paths for these
161 file types. Note the processes UID still need to have DAC permissions.
162
163 ipa_log_t
164
165 /var/log/ipa(/.*)?
166 /var/log/ipareplica-conncheck.log.*
167
168 ipa_var_run_t
169
170 /var/run/ipa(/.*)?
171
172 sssd_var_lib_t
173
174 /var/lib/sss(/.*)?
175
176
178 SELinux requires files to have an extended attribute to define the file
179 type.
180
181 You can see the context of a file using the -Z option to ls
182
183 Policy governs the access confined processes have to these files.
184 SELinux ipa_helper policy is very flexible allowing users to setup
185 their ipa_helper processes in as secure a method as possible.
186
187 The following file types are defined for ipa_helper:
188
189
190
191 ipa_helper_exec_t
192
193 - Set files with the ipa_helper_exec_t type, if you want to transition
194 an executable to the ipa_helper_t domain.
195
196
197 Paths:
198 /usr/libexec/ipa/com.redhat.idm.trust-fetch-domains,
199 /usr/libexec/ipa/oddjob/org.freeipa.server.conncheck,
200 /usr/libexec/ipa/oddjob/com.redhat.idm.trust-fetch-domains
201
202
203 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
208
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212
213 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215
216 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218
219 semanage boolean can also be used to manipulate the booleans
220
221
222 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
