NAME

6       ypbind_selinux  -  Security  Enhanced  Linux Policy for the ypbind pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  ypbind  processes  via  flexible
11       mandatory access control.
12
13       The  ypbind  processes  execute with the ypbind_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 ypbind_t
20
21
22

ENTRYPOINTS

24       The  ypbind_t  SELinux  type  can be entered via the ypbind_exec_t file
25       type.
26
27       The default entrypoint paths for the ypbind_t domain are the following:
28
29       /sbin/ypbind, /usr/sbin/ypbind
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       ypbind policy is very flexible allowing users  to  setup  their  ypbind
39       processes in as secure a method as possible.
40
41       The following process types are defined for ypbind:
42
43       ypbind_t
44
45       Note:  semanage  permissive -a ypbind_t can be used to make the process
46       type ypbind_t permissive. SELinux does not deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.

BOOLEANS

52       SELinux policy is customizable based on least access required.   ypbind
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run ypbind with the tightest access possible.

MANAGED FILES

131       The SELinux process type ypbind_t can manage  files  labeled  with  the
132       following file types.  The paths listed are the default paths for these
133       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

205       SELinux requires files to have an extended attribute to define the file
206       type.
207
208       You can see the context of a file using the -Z option to ls
209
210       Policy  governs  the  access  confined  processes  have to these files.
211       SELinux ypbind policy is very flexible allowing users  to  setup  their
212       ypbind processes in as secure a method as possible.
213
214       STANDARD FILE CONTEXT
215
216       SELinux defines the file context types for the ypbind, if you wanted to
217       store files with these types in a diffent paths, you  need  to  execute
218       the  semanage  command  to  sepecify  alternate  labeling  and then use
219       restorecon to put the labels on disk.
220
221       semanage fcontext -a -t ypbind_var_run_t '/srv/myypbind_content(/.*)?'
222       restorecon -R -v /srv/myypbind_content
223
224       Note: SELinux often uses regular expressions  to  specify  labels  that
225       match multiple files.
226
227       The following file types are defined for ypbind:
228
229
230
231       ypbind_exec_t
232
233       -  Set  files with the ypbind_exec_t type, if you want to transition an
234       executable to the ypbind_t domain.
235
236
237       Paths:
238            /sbin/ypbind, /usr/sbin/ypbind
239
240
241       ypbind_initrc_exec_t
242
243       - Set files with the ypbind_initrc_exec_t type, if you want to  transi‐
244       tion an executable to the ypbind_initrc_t domain.
245
246
247
248       ypbind_tmp_t
249
250       -  Set  files  with  the ypbind_tmp_t type, if you want to store ypbind
251       temporary files in the /tmp directories.
252
253
254
255       ypbind_var_run_t
256
257       - Set files with the ypbind_var_run_t type, if you want  to  store  the
258       ypbind files under the /run or /var/run directory.
259
260
261
262       Note:  File context can be temporarily modified with the chcon command.
263       If you want to permanently change the file context you need to use  the
264       semanage fcontext command.  This will modify the SELinux labeling data‐
265       base.  You will need to use restorecon to apply the labels.
266
267

COMMANDS

269       semanage fcontext can also be used to manipulate default  file  context
270       mappings.
271
272       semanage  permissive  can  also  be used to manipulate whether or not a
273       process type is permissive.
274
275       semanage module can also be used to enable/disable/install/remove  pol‐
276       icy modules.
277
278       semanage boolean can also be used to manipulate the booleans
279
280
281       system-config-selinux is a GUI tool available to customize SELinux pol‐
282       icy settings.
