NAME

6       namespace_init_selinux  -  Security Enhanced Linux Policy for the name‐
7       space_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  name‐
25       space_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.  name‐
54       space_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 system to run with  NIS,  you  must  turn  on  the
61       nis_enabled boolean. Disabled by default.
62
63       setsebool -P nis_enabled 1
64
65
66
67       If you want to enable polyinstantiated directory support, you must turn
68       on the polyinstantiation_enabled boolean. Disabled by default.
69
70       setsebool -P polyinstantiation_enabled 1

MANAGED FILES

75       The SELinux process type namespace_init_t can manage files labeled with
76       the  following  file types.  The paths listed are the default paths for
77       these file types.  Note the processes UID still need to have  DAC  per‐
78       missions.
79
80       krb5_host_rcache_t
81
82            /var/tmp/krb5_0.rcache2
83            /var/cache/krb5rcache(/.*)?
84            /var/tmp/nfs_0
85            /var/tmp/DNS_25
86            /var/tmp/host_0
87            /var/tmp/imap_0
88            /var/tmp/HTTP_23
89            /var/tmp/HTTP_48
90            /var/tmp/ldap_55
91            /var/tmp/ldap_487
92            /var/tmp/ldapmap1_0

94       security_t

96            /selinux

99
100            all user home files

FILE CONTEXTS

104       SELinux requires files to have an extended attribute to define the file
105       type.
106
107       You can see the context of a file using the -Z option to ls
108
109       Policy governs the access  confined  processes  have  to  these  files.
110       SELinux  namespace_init policy is very flexible allowing users to setup
111       their namespace_init processes in as secure a method as possible.
112
113       STANDARD FILE CONTEXT
114
115       SELinux defines the file context types for the namespace_init,  if  you
116       wanted  to  store files with these types in a different paths, you need
117       to execute the semanage command to specify alternate labeling and  then
118       use restorecon to put the labels on disk.
119
120       semanage fcontext -a -t namespace_init_exec_t '/srv/namespace_init/con‐
121       tent(/.*)?'
122       restorecon -R -v /srv/mynamespace_init_content
123
124       Note: SELinux often uses regular expressions  to  specify  labels  that
125       match multiple files.
126
127       The following file types are defined for namespace_init:
128
129
130
131       namespace_init_exec_t
132
133       - Set files with the namespace_init_exec_t type, if you want to transi‐
134       tion an executable to the namespace_init_t domain.
135
136
137       Paths:
138            /etc/security/namespace.init, /etc/security/namespace.d(/.*)?
139
140
141       Note: File context can be temporarily modified with the chcon  command.
142       If  you want to permanently change the file context you need to use the
143       semanage fcontext command.  This will modify the SELinux labeling data‐
144       base.  You will need to use restorecon to apply the labels.
145
146

COMMANDS

148       semanage  fcontext  can also be used to manipulate default file context
149       mappings.
150
151       semanage permissive can also be used to manipulate  whether  or  not  a
152       process type is permissive.
153
154       semanage  module can also be used to enable/disable/install/remove pol‐
155       icy modules.
156
157       semanage boolean can also be used to manipulate the booleans
158
159
160       system-config-selinux is a GUI tool available to customize SELinux pol‐
161       icy settings.
