NAME

6       namespace_init_selinux  - Security Enhanced Linux Policy for the names‐
7       pace_init processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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.

51

BOOLEANS

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. Enabled 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

MANAGED FILES

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

FILE CONTEXTS

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

COMMANDS

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.
