NAME

6       utempter_selinux - Security Enhanced Linux Policy for the utempter pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  utempter  processes  via  flexible
11       mandatory access control.
12
13       The  utempter  processes  execute with the utempter_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep utempter_t
20
21
22

ENTRYPOINTS

24       The utempter_t SELinux type can be entered via the utempter_exec_t file
25       type.
26
27       The default entrypoint paths for the utempter_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/utempter
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       utempter policy is very flexible allowing users to setup their utempter
40       processes in as secure a method as possible.
41
42       The following process types are defined for utempter:
43
44       utempter_t
45
46       Note: semanage permissive -a utempter_t can be used to make the process
47       type  utempter_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

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       utempter policy is extremely flexible and  has  several  booleans  that
55       allow  you  to manipulate the policy and run utempter with the tightest
56       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

MANAGED FILES

97       The SELinux process type utempter_t can manage files labeled  with  the
98       following file types.  The paths listed are the default paths for these
99       file types.  Note the processes UID still need to have DAC permissions.
100
101       initrc_var_run_t
102
103            /var/run/utmp
104            /var/run/random-seed
105            /var/run/runlevel.dir
106            /var/run/setmixer_flag
107
108       user_tmp_t
109
110            /dev/shm/mono.*
111            /var/run/user(/.*)?
112            /tmp/.ICE-unix(/.*)?
113            /tmp/.X11-unix(/.*)?
114            /dev/shm/pulse-shm.*
115            /tmp/.X0-lock
116            /tmp/hsperfdata_root
117            /var/tmp/hsperfdata_root
118            /home/[^/]+/tmp
119            /home/[^/]+/.tmp
120            /tmp/gconfd-[^/]+
121
122       wtmp_t
123
124            /var/log/wtmp.*
125
126

FILE CONTEXTS

128       SELinux requires files to have an extended attribute to define the file
129       type.
130
131       You can see the context of a file using the -Z option to ls
132
133       Policy  governs  the  access  confined  processes  have to these files.
134       SELinux utempter policy is very flexible allowing users to setup  their
135       utempter processes in as secure a method as possible.
136
137       The following file types are defined for utempter:
138
139
140
141       utempter_exec_t
142
143       - Set files with the utempter_exec_t type, if you want to transition an
144       executable to the utempter_t domain.
145
146
147
148       Note: File context can be temporarily modified with the chcon  command.
149       If  you want to permanently change the file context you need to use the
150       semanage fcontext command.  This will modify the SELinux labeling data‐
151       base.  You will need to use restorecon to apply the labels.
152
153

COMMANDS

155       semanage  fcontext  can also be used to manipulate default file context
156       mappings.
157
158       semanage permissive can also be used to manipulate  whether  or  not  a
159       process type is permissive.
160
161       semanage  module can also be used to enable/disable/install/remove pol‐
162       icy modules.
163
164       semanage boolean can also be used to manipulate the booleans
165
166
167       system-config-selinux is a GUI tool available to customize SELinux pol‐
168       icy settings.
