NAME

6       updpwd_selinux  -  Security  Enhanced  Linux Policy for the updpwd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  updpwd  processes  via  flexible
11       mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep updpwd_t
20
21
22

ENTRYPOINTS

24       The  updpwd_t  SELinux  type  can be entered via the updpwd_exec_t file
25       type.
26
27       The default entrypoint paths for the updpwd_t domain are the following:
28
29       /sbin/unix_update, /usr/sbin/unix_update, /usr/sbin/pwhistory_helper
30

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       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
41       The following process types are defined for updpwd:
42
43       updpwd_t
44
45       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
50

BOOLEANS

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
56
57
58       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‐

MANAGED FILES

155       The SELinux process type updpwd_t can manage  files  labeled  with  the
156       following file types.  The paths listed are the default paths for these
157       file types.  Note the processes UID still need to have DAC permissions.
158
159       etc_t
160
161            /etc/.*
162            /usr/etc(/.*)?
163            /var/ftp/etc(/.*)?
164            /var/lib/openshift/.limits.d(/.*)?

FILE CONTEXTS

197       SELinux requires files to have an extended attribute to define the file
198       type.
199
200       You can see the context of a file using the -Z option to ls
201
202       Policy  governs  the  access  confined  processes  have to these files.
203       SELinux updpwd policy is very flexible allowing users  to  setup  their
204       updpwd processes in as secure a method as possible.
205
206       The following file types are defined for updpwd:
207
208
209
210       updpwd_exec_t
211
212       -  Set  files with the updpwd_exec_t type, if you want to transition an
213       executable to the updpwd_t domain.
214
215
216       Paths:
217            /sbin/unix_update,     /usr/sbin/unix_update,     /usr/sbin/pwhis‐
218            tory_helper
219
220
221       Note:  File context can be temporarily modified with the chcon command.
222       If you want to permanently change the file context you need to use  the
223       semanage fcontext command.  This will modify the SELinux labeling data‐
224       base.  You will need to use restorecon to apply the labels.
225
226

COMMANDS

228       semanage fcontext can also be used to manipulate default  file  context
229       mappings.
230
231       semanage  permissive  can  also  be used to manipulate whether or not a
232       process type is permissive.
233
234       semanage module can also be used to enable/disable/install/remove  pol‐
235       icy modules.
236
237       semanage boolean can also be used to manipulate the booleans
238
239
240       system-config-selinux is a GUI tool available to customize SELinux pol‐
241       icy settings.
