NAME

6       sulogin_selinux  -  Security Enhanced Linux Policy for the sulogin pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

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       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.

51

BOOLEANS

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.
57
58
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

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

MANAGED FILES

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.
136
137       initrc_tmp_t
138
139
140       mnt_t
141
142            /mnt(/[^/]*)
143            /mnt(/[^/]*)?
144            /rhev(/[^/]*)?
145            /media(/[^/]*)
146            /media(/[^/]*)?
147            /etc/rhgb(/.*)?
148            /media/.hal-.*
149            /net
150            /afs
151            /rhev
152            /misc
153
154       security_t
155
156
157       tmp_t
158
159            /tmp
160            /usr/tmp
161            /var/tmp
162            /tmp-inst
163            /var/tmp-inst
164            /var/tmp/vi.recover

FILE CONTEXTS

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

COMMANDS

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.
