6 sulogin_selinux - Security Enhanced Linux Policy for the sulogin pro‐
7 cesses
8
10 Security-Enhanced Linux secures the sulogin processes via flexible
11 mandatory access control.
12
13 The sulogin processes execute with the sulogin_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sulogin_t
20
21
22
24 The sulogin_t SELinux type can be entered via the sulogin_exec_t file
25 type.
26
27 The default entrypoint paths for the sulogin_t domain are the follow‐
28 ing:
29
30 /sbin/sulogin, /sbin/sushell
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 sulogin policy is very flexible allowing users to setup their sulogin
40 processes in as secure a method as possible.
41
42 The following process types are defined for sulogin:
43
44 sulogin_t
45
46 Note: semanage permissive -a sulogin_t can be used to make the process
47 type sulogin_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. sulogin
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run sulogin with the tightest access possi‐
56 ble.

59
60 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
64 setsebool -P allow_daemons_use_tty 1
65
66
67
68 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
71 setsebool -P allow_domain_fd_use 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the allow_kerberos boolean. Enabled by default.
77
78 setsebool -P allow_kerberos 1
79
80
81
82 If you want to allow sysadm to debug or ptrace all processes, you must
83 turn on the allow_ptrace boolean. Disabled by default.
84
85 setsebool -P allow_ptrace 1
86
87
88
89 If you want to allow system to run with NIS, you must turn on the
90 allow_ypbind boolean. Disabled by default.
91
92 setsebool -P allow_ypbind 1
93
94
95
96 If you want to allow all domains to have the kernel load modules, you
97 must turn on the domain_kernel_load_modules boolean. Disabled by
98 default.
99
100 setsebool -P domain_kernel_load_modules 1
101
102
103
104 If you want to allow all domains to execute in fips_mode, you must turn
105 on the fips_mode boolean. Enabled by default.
106
107 setsebool -P fips_mode 1
108
109
110
111 If you want to enable reading of urandom for all domains, you must turn
112 on the global_ssp boolean. Disabled by default.
113
114 setsebool -P global_ssp 1
115
116
117
118 If you want to allow confined applications to use nscd shared memory,
119 you must turn on the nscd_use_shm boolean. Enabled by default.
120
121 setsebool -P nscd_use_shm 1
122
123
124
125 If you want to allow a user to login as an unconfined domain, you must
126 turn on the unconfined_login boolean. Enabled by default.
127
128 setsebool -P unconfined_login 1
129
130
131
133 The SELinux process type sulogin_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

142 /mnt(/[^/]*)

168 SELinux requires files to have an extended attribute to define the file
169 type.
170
171 You can see the context of a file using the -Z option to ls
172
173 Policy governs the access confined processes have to these files.
174 SELinux sulogin policy is very flexible allowing users to setup their
175 sulogin processes in as secure a method as possible.
176
177 The following file types are defined for sulogin:
178
179
180
181 sulogin_exec_t
182
183 - Set files with the sulogin_exec_t type, if you want to transition an
184 executable to the sulogin_t domain.
185
186
187 Paths:
188 /sbin/sulogin, /sbin/sushell
189
190
191 Note: File context can be temporarily modified with the chcon command.
192 If you want to permanently change the file context you need to use the
193 semanage fcontext command. This will modify the SELinux labeling data‐
194 base. You will need to use restorecon to apply the labels.
195
196
198 semanage fcontext can also be used to manipulate default file context
199 mappings.
200
201 semanage permissive can also be used to manipulate whether or not a
202 process type is permissive.
203
204 semanage module can also be used to enable/disable/install/remove pol‐
205 icy modules.
206
207 semanage boolean can also be used to manipulate the booleans
208
209
210 system-config-selinux is a GUI tool available to customize SELinux pol‐
211 icy settings.
