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.
65
66 setsebool -P authlogin_nsswitch_use_ldap 1
67
68
69
70 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72
73 setsebool -P fips_mode 1
74
75
76
77 If you want to allow httpd processes to run IPA helper, you must turn
78 on the httpd_run_ipa boolean. Disabled by default.
79
80 setsebool -P httpd_run_ipa 1
81
82
83
84 If you want to allow confined applications to run with kerberos, you
85 must turn on the kerberos_enabled boolean. Enabled by default.
86
87 setsebool -P kerberos_enabled 1
88
89
90
91 If you want to allow system to run with NIS, you must turn on the
92 nis_enabled boolean. Disabled by default.
93
94 setsebool -P nis_enabled 1
95
96
97
98 If you want to allow confined applications to use nscd shared memory,
99 you must turn on the nscd_use_shm boolean. Disabled by default.
100
101 setsebool -P nscd_use_shm 1
102
103
104
106 The SELinux process type ipa_helper_t can manage files labeled with the
107 following file types. The paths listed are the default paths for these
108 file types. Note the processes UID still need to have DAC permissions.
109
110 ipa_log_t
111
112 /var/log/ipa(/.*)?
113 /var/log/ipareplica-conncheck.log.*
114
115 ipa_var_run_t
116
117 /var/run/ipa(/.*)?
118
119 sssd_var_lib_t
120
121 /var/lib/sss(/.*)?
122
123
125 SELinux requires files to have an extended attribute to define the file
126 type.
127
128 You can see the context of a file using the -Z option to ls
129
130 Policy governs the access confined processes have to these files.
131 SELinux ipa_helper policy is very flexible allowing users to setup
132 their ipa_helper processes in as secure a method as possible.
133
134 The following file types are defined for ipa_helper:
135
136
137
138 ipa_helper_exec_t
139
140 - Set files with the ipa_helper_exec_t type, if you want to transition
141 an executable to the ipa_helper_t domain.
142
143
144 Paths:
145 /usr/libexec/ipa/com.redhat.idm.trust-fetch-domains,
146 /usr/libexec/ipa/oddjob/org.freeipa.server.conncheck,
147 /usr/libexec/ipa/oddjob/com.redhat.idm.trust-fetch-domains
148
149
150 Note: File context can be temporarily modified with the chcon command.
151 If you want to permanently change the file context you need to use the
152 semanage fcontext command. This will modify the SELinux labeling data‐
153 base. You will need to use restorecon to apply the labels.
154
155
157 semanage fcontext can also be used to manipulate default file context
158 mappings.
159
160 semanage permissive can also be used to manipulate whether or not a
161 process type is permissive.
162
163 semanage module can also be used to enable/disable/install/remove pol‐
164 icy modules.
165
166 semanage boolean can also be used to manipulate the booleans
167
168
169 system-config-selinux is a GUI tool available to customize SELinux pol‐
170 icy settings.
