6 utempter_selinux - Security Enhanced Linux Policy for the utempter pro‐
7 cesses
8
10 Security-Enhanced Linux secures the utempter processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep utempter_t
20
24 The utempter_t SELinux type can be entered via the utempter_exec_t file
25 type.
26 The default entrypoint paths for the utempter_t domain are the follow‐
28 ing:
29 /usr/sbin/utempter, /usr/libexec/utempter/utempter
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for utempter:
43 utempter_t
45 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
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 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 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
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 initrc_var_run_t
80 /var/run/utmp
82 /var/run/random-seed
83 /var/run/runlevel.dir
84 /var/run/setmixer_flag
85 wtmp_t
87 /var/log/wtmp.*

92 SELinux requires files to have an extended attribute to define the file
93 type.
94 You can see the context of a file using the -Z option to ls
96 Policy governs the access confined processes have to these files.
98 SELinux utempter policy is very flexible allowing users to setup their
99 utempter processes in as secure a method as possible.
100 The following file types are defined for utempter:
102 utempter_exec_t
106 - Set files with the utempter_exec_t type, if you want to transition an
108 executable to the utempter_t domain.
109 Paths:
112 /usr/sbin/utempter, /usr/libexec/utempter/utempter
113 Note: File context can be temporarily modified with the chcon command.
116 If you want to permanently change the file context you need to use the
117 semanage fcontext command. This will modify the SELinux labeling data‐
118 base. You will need to use restorecon to apply the labels.
119
122 semanage fcontext can also be used to manipulate default file context
123 mappings.
124 semanage permissive can also be used to manipulate whether or not a
126 process type is permissive.
127 semanage module can also be used to enable/disable/install/remove pol‐
129 icy modules.
130 semanage boolean can also be used to manipulate the booleans
132 system-config-selinux is a GUI tool available to customize SELinux pol‐
135 icy settings.
