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, /usr/libexec/utempter/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 al‐
55       low you to manipulate the policy and run utempter with the tightest ac‐
56       cess possible.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1
64
65
66
67       If  you  want  to  allow  system  to run with NIS, you must turn on the
68       nis_enabled boolean. Disabled by default.
69
70       setsebool -P nis_enabled 1
71
72
73

MANAGED FILES

75       The SELinux process type utempter_t can manage files labeled  with  the
76       following file types.  The paths listed are the default paths for these
77       file types.  Note the processes UID still need to have DAC permissions.
78
79       initrc_var_run_t
80
81            /var/run/utmp
82            /var/run/random-seed
83            /var/run/runlevel.dir
84            /var/run/setmixer_flag
85
86       krb5_host_rcache_t
87
88            /var/tmp/krb5_0.rcache2
89            /var/cache/krb5rcache(/.*)?
90            /var/tmp/nfs_0
91            /var/tmp/DNS_25
92            /var/tmp/host_0
93            /var/tmp/imap_0
94            /var/tmp/HTTP_23
95            /var/tmp/HTTP_48
96            /var/tmp/ldap_55
97            /var/tmp/ldap_487
98            /var/tmp/ldapmap1_0
99
100       wtmp_t
101
102            /var/log/wtmp.*
103
104

FILE CONTEXTS

106       SELinux requires files to have an extended attribute to define the file
107       type.
108
109       You can see the context of a file using the -Z option to ls
110
111       Policy  governs  the  access  confined  processes  have to these files.
112       SELinux utempter policy is very flexible allowing users to setup  their
113       utempter processes in as secure a method as possible.
114
115       STANDARD FILE CONTEXT
116
117       SELinux  defines the file context types for the utempter, if you wanted
118       to store files with these types in a different paths, you need to  exe‐
119       cute  the  semanage  command to specify alternate labeling and then use
120       restorecon to put the labels on disk.
121
122       semanage fcontext -a -t utempter_exec_t '/srv/utempter/content(/.*)?'
123       restorecon -R -v /srv/myutempter_content
124
125       Note: SELinux often uses regular expressions  to  specify  labels  that
126       match multiple files.
127
128       The following file types are defined for utempter:
129
130
131
132       utempter_exec_t
133
134       - Set files with the utempter_exec_t type, if you want to transition an
135       executable to the utempter_t domain.
136
137
138       Paths:
139            /usr/sbin/utempter, /usr/libexec/utempter/utempter
140
141
142       Note: File context can be temporarily modified with the chcon  command.
143       If  you want to permanently change the file context you need to use the
144       semanage fcontext command.  This will modify the SELinux labeling data‐
145       base.  You will need to use restorecon to apply the labels.
146
147

COMMANDS

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