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 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 For example:
18 ps -eZ | grep namespace_init_t
20
24 The namespace_init_t SELinux type can be entered via the names‐
25 pace_init_exec_t file type.
26 The default entrypoint paths for the namespace_init_t domain are the
28 following:
29 /etc/security/namespace.init
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for namespace_init:
43 namespace_init_t
45 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
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 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63 setsebool -P allow_daemons_use_tty 1
65 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70 setsebool -P allow_domain_fd_use 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the allow_kerberos boolean. Enabled by default.
77 setsebool -P allow_kerberos 1
79 If you want to enable polyinstantiated directory support, you must turn
83 on the allow_polyinstantiation boolean. Enabled by default.
84 setsebool -P allow_polyinstantiation 1
86 If you want to allow sysadm to debug or ptrace all processes, you must
90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1
93 If you want to allow system to run with NIS, you must turn on the
97 allow_ypbind boolean. Disabled by default.
98 setsebool -P allow_ypbind 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to allow confined applications to use nscd shared memory,
126 you must turn on the nscd_use_shm boolean. Enabled by default.
127 setsebool -P nscd_use_shm 1
129
133 The SELinux process type namespace_init_t can manage files labeled with
134 the following file types. The paths listed are the default paths for
135 these file types. Note the processes UID still need to have DAC per‐
136 missions.
137 initrc_tmp_t
139 mnt_t
142 /mnt(/[^/]*)
144 /mnt(/[^/]*)?
145 /rhev(/[^/]*)?
146 /media(/[^/]*)
147 /media(/[^/]*)?
148 /etc/rhgb(/.*)?
149 /media/.hal-.*
150 /net
151 /afs
152 /rhev
153 /misc
154 security_t
156 tmp_t
159 /tmp
161 /usr/tmp
162 /var/tmp
163 /tmp-inst
164 /var/tmp-inst
165 /var/tmp/vi.recover
166 user_home_t
168 /home/[^/]*/.+
170 /home/staff/.+

174 SELinux requires files to have an extended attribute to define the file
175 type.
176 You can see the context of a file using the -Z option to ls
178 Policy governs the access confined processes have to these files.
180 SELinux namespace_init policy is very flexible allowing users to setup
181 their namespace_init processes in as secure a method as possible.
182 The following file types are defined for namespace_init:
184 namespace_init_exec_t
188 - Set files with the namespace_init_exec_t type, if you want to transi‐
190 tion an executable to the namespace_init_t domain.
191 Note: File context can be temporarily modified with the chcon command.
195 If you want to permanently change the file context you need to use the
196 semanage fcontext command. This will modify the SELinux labeling data‐
197 base. You will need to use restorecon to apply the labels.
198
201 semanage fcontext can also be used to manipulate default file context
202 mappings.
203 semanage permissive can also be used to manipulate whether or not a
205 process type is permissive.
206 semanage module can also be used to enable/disable/install/remove pol‐
208 icy modules.
209 semanage boolean can also be used to manipulate the booleans
211 system-config-selinux is a GUI tool available to customize SELinux pol‐
214 icy settings.
