6 updpwd_selinux - Security Enhanced Linux Policy for the updpwd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the updpwd processes via flexible
11 mandatory access control.
12 The updpwd processes execute with the updpwd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep updpwd_t
20
24 The updpwd_t SELinux type can be entered via the updpwd_exec_t file
25 type.
26 The default entrypoint paths for the updpwd_t domain are the following:
28 /sbin/unix_update, /usr/sbin/unix_update, /usr/sbin/pwhistory_helper
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 Policy governs the access confined processes have to files. SELinux
38 updpwd policy is very flexible allowing users to setup their updpwd
39 processes in as secure a method as possible.
40 The following process types are defined for updpwd:
42 updpwd_t
44 Note: semanage permissive -a updpwd_t can be used to make the process
46 type updpwd_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
52 SELinux policy is customizable based on least access required. updpwd
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run updpwd with the tightest access possible.
55 If you want to allow users to resolve user passwd entries directly from
59 ldap rather then using a sssd server, you must turn on the authlo‐
60 gin_nsswitch_use_ldap boolean. Disabled by default.
61 setsebool -P authlogin_nsswitch_use_ldap 1
63 If you want to allow all domains to execute in fips_mode, you must turn
67 on the fips_mode boolean. Enabled by default.
68 setsebool -P fips_mode 1
70 If you want to allow Apache to use mod_auth_pam, you must turn on the
74 httpd_mod_auth_pam boolean. Disabled by default.
75 setsebool -P httpd_mod_auth_pam 1
77 If you want to allow confined applications to run with kerberos, you
81 must turn on the kerberos_enabled boolean. Enabled by default.
82 setsebool -P kerberos_enabled 1
84 If you want to allow nagios/nrpe to call sudo from NRPE utils scripts,
88 you must turn on the nagios_run_sudo boolean. Disabled by default.
89 setsebool -P nagios_run_sudo 1
91 If you want to allow system to run with NIS, you must turn on the
95 nis_enabled boolean. Disabled by default.
96 setsebool -P nis_enabled 1
98 If you want to allow confined applications to use nscd shared memory,
102 you must turn on the nscd_use_shm boolean. Enabled by default.
103 setsebool -P nscd_use_shm 1
105
109 The SELinux process type updpwd_t can manage files labeled with the
110 following file types. The paths listed are the default paths for these
111 file types. Note the processes UID still need to have DAC permissions.

154 SELinux requires files to have an extended attribute to define the file
155 type.
156 You can see the context of a file using the -Z option to ls
158 Policy governs the access confined processes have to these files.
160 SELinux updpwd policy is very flexible allowing users to setup their
161 updpwd processes in as secure a method as possible.
162 The following file types are defined for updpwd:
164 updpwd_exec_t
168 - Set files with the updpwd_exec_t type, if you want to transition an
170 executable to the updpwd_t domain.
171 Paths:
174 /sbin/unix_update, /usr/sbin/unix_update, /usr/sbin/pwhis‐
175 tory_helper
176 Note: File context can be temporarily modified with the chcon command.
179 If you want to permanently change the file context you need to use the
180 semanage fcontext command. This will modify the SELinux labeling data‐
181 base. You will need to use restorecon to apply the labels.
182
185 semanage fcontext can also be used to manipulate default file context
186 mappings.
187 semanage permissive can also be used to manipulate whether or not a
189 process type is permissive.
190 semanage module can also be used to enable/disable/install/remove pol‐
192 icy modules.
193 semanage boolean can also be used to manipulate the booleans
195 system-config-selinux is a GUI tool available to customize SELinux pol‐
198 icy settings.
