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
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 all domains to use other domains file descriptors,
59 you must turn on the allow_domain_fd_use boolean. Enabled by default.
60 setsebool -P allow_domain_fd_use 1
62 If you want to allow Apache to use mod_auth_pam, you must turn on the
66 allow_httpd_mod_auth_pam boolean. Disabled by default.
67 setsebool -P allow_httpd_mod_auth_pam 1
69 If you want to allow confined applications to run with kerberos, you
73 must turn on the allow_kerberos boolean. Enabled by default.
74 setsebool -P allow_kerberos 1
76 If you want to allow sysadm to debug or ptrace all processes, you must
80 turn on the allow_ptrace boolean. Disabled by default.
81 setsebool -P allow_ptrace 1
83 If you want to allow system to run with NIS, you must turn on the
87 allow_ypbind boolean. Disabled by default.
88 setsebool -P allow_ypbind 1
90 If you want to allow all domains to have the kernel load modules, you
94 must turn on the domain_kernel_load_modules boolean. Disabled by
95 default.
96 setsebool -P domain_kernel_load_modules 1
98 If you want to allow all domains to execute in fips_mode, you must turn
102 on the fips_mode boolean. Enabled by default.
103 setsebool -P fips_mode 1
105 If you want to enable reading of urandom for all domains, you must turn
109 on the global_ssp boolean. Disabled by default.
110 setsebool -P global_ssp 1
112 If you want to allow nagios/nrpe to call sudo from NRPE utils scripts,
116 you must turn on the nagios_run_sudo boolean. Disabled by default.
117 setsebool -P nagios_run_sudo 1
119 If you want to allow confined applications to use nscd shared memory,
123 you must turn on the nscd_use_shm boolean. Enabled by default.
124 setsebool -P nscd_use_shm 1
126
130 The SELinux process type updpwd_t can manage files labeled with the
131 following file types. The paths listed are the default paths for these
132 file types. Note the processes UID still need to have DAC permissions.

190 SELinux requires files to have an extended attribute to define the file
191 type.
192 You can see the context of a file using the -Z option to ls
194 Policy governs the access confined processes have to these files.
196 SELinux updpwd policy is very flexible allowing users to setup their
197 updpwd processes in as secure a method as possible.
198 The following file types are defined for updpwd:
200 updpwd_exec_t
204 - Set files with the updpwd_exec_t type, if you want to transition an
206 executable to the updpwd_t domain.
207 Note: File context can be temporarily modified with the chcon command.
211 If you want to permanently change the file context you need to use the
212 semanage fcontext command. This will modify the SELinux labeling data‐
213 base. You will need to use restorecon to apply the labels.
214
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225 semanage boolean can also be used to manipulate the booleans
227 system-config-selinux is a GUI tool available to customize SELinux pol‐
230 icy settings.
