6 namespace_init_selinux - Security Enhanced Linux Policy for the names‐
7 pace_init processes
8
10 Security-Enhanced Linux secures the namespace_init processes via flexi‐
11 ble mandatory access control.
12
13 The namespace_init processes execute with the namespace_init_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep namespace_init_t
20
21
22
24 The namespace_init_t SELinux type can be entered via the names‐
25 pace_init_exec_t file type.
26
27 The default entrypoint paths for the namespace_init_t domain are the
28 following:
29
30 /etc/security/namespace.init, /etc/security/namespace.d(/.*)?
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 namespace_init policy is very flexible allowing users to setup their
40 namespace_init processes in as secure a method as possible.
41
42 The following process types are defined for namespace_init:
43
44 namespace_init_t
45
46 Note: semanage permissive -a namespace_init_t can be used to make the
47 process type namespace_init_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. names‐
54 pace_init policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run namespace_init with the
56 tightest access possible.
57
58
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‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 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
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
96 If you want to enable polyinstantiated directory support, you must turn
97 on the polyinstantiation_enabled boolean. Disabled by default.
98
99 setsebool -P polyinstantiation_enabled 1

102
104 The SELinux process type namespace_init_t can manage files labeled with
105 the following file types. The paths listed are the default paths for
106 these file types. Note the processes UID still need to have DAC per‐
107 missions.
108
109 security_t
110
111 /selinux
112
113 user_home_type
114
115 all user home files
116
117
119 SELinux requires files to have an extended attribute to define the file
120 type.
121
122 You can see the context of a file using the -Z option to ls
123
124 Policy governs the access confined processes have to these files.
125 SELinux namespace_init policy is very flexible allowing users to setup
126 their namespace_init processes in as secure a method as possible.
127
128 The following file types are defined for namespace_init:
129
130
131
132 namespace_init_exec_t
133
134 - Set files with the namespace_init_exec_t type, if you want to transi‐
135 tion an executable to the namespace_init_t domain.
136
137
138 Paths:
139 /etc/security/namespace.init, /etc/security/namespace.d(/.*)?
140
141
142 Note: File context can be temporarily modified with the chcon command.
143 If you want to permanently change the file context you need to use the
144 semanage fcontext command. This will modify the SELinux labeling data‐
145 base. You will need to use restorecon to apply the labels.
146
147
149 semanage fcontext can also be used to manipulate default file context
150 mappings.
151
152 semanage permissive can also be used to manipulate whether or not a
153 process type is permissive.
154
155 semanage module can also be used to enable/disable/install/remove pol‐
156 icy modules.
157
158 semanage boolean can also be used to manipulate the booleans
159
160
161 system-config-selinux is a GUI tool available to customize SELinux pol‐
162 icy settings.
