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 all domains to use other domains file descriptors,
61       you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63       setsebool -P allow_domain_fd_use 1
64
65
66
67       If  you want to allow sysadm to debug or ptrace all processes, you must
68       turn on the allow_ptrace boolean. Disabled by default.
69
70       setsebool -P allow_ptrace 1
71
72
73
74       If you want to allow all domains to have the kernel load  modules,  you
75       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
76       default.
77
78       setsebool -P domain_kernel_load_modules 1
79
80
81
82       If you want to allow all domains to execute in fips_mode, you must turn
83       on the fips_mode boolean. Enabled by default.
84
85       setsebool -P fips_mode 1
86
87
88
89       If you want to enable reading of urandom for all domains, you must turn
90       on the global_ssp boolean. Disabled by default.
91
92       setsebool -P global_ssp 1

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.

FILE CONTEXTS

145       SELinux requires files to have an extended attribute to define the file
146       type.
147
148       You can see the context of a file using the -Z option to ls
149
150       Policy  governs  the  access  confined  processes  have to these files.
151       SELinux utempter policy is very flexible allowing users to setup  their
152       utempter processes in as secure a method as possible.
153
154       The following file types are defined for utempter:
155
156
157
158       utempter_exec_t
159
160       - Set files with the utempter_exec_t type, if you want to transition an
161       executable to the utempter_t domain.
162
163
164
165       Note: File context can be temporarily modified with the chcon  command.
166       If  you want to permanently change the file context you need to use the
167       semanage fcontext command.  This will modify the SELinux labeling data‐
168       base.  You will need to use restorecon to apply the labels.

170

COMMANDS

172       semanage  fcontext  can also be used to manipulate default file context
173       mappings.
174
175       semanage permissive can also be used to manipulate  whether  or  not  a
176       process type is permissive.
177
178       semanage  module can also be used to enable/disable/install/remove pol‐
179       icy modules.
180
181       semanage boolean can also be used to manipulate the booleans
182
183
184       system-config-selinux is a GUI tool available to customize SELinux pol‐
185       icy settings.
