6 ypxfr_selinux - Security Enhanced Linux Policy for the ypxfr processes
7
9 Security-Enhanced Linux secures the ypxfr processes via flexible manda‐
10 tory access control.
11
12 The ypxfr processes execute with the ypxfr_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep ypxfr_t
19
20
21
23 The ypxfr_t SELinux type can be entered via the ypxfr_exec_t file type.
24
25 The default entrypoint paths for the ypxfr_t domain are the following:
26
27 /usr/lib/yp/ypxfr, /usr/lib64/yp/ypxfr, /usr/sbin/rpc.ypxfrd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 ypxfr policy is very flexible allowing users to setup their ypxfr pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for ypxfr:
40
41 ypxfr_t
42
43 Note: semanage permissive -a ypxfr_t can be used to make the process
44 type ypxfr_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. ypxfr
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run ypxfr with the tightest access possible.

119
120

122 turn on the init_upstart boolean. Enabled by default.
123
124 setsebool -P init_upstart 1
125
126
127
129 The SELinux process type ypxfr_t can manage files labeled with the fol‐
130 lowing file types. The paths listed are the default paths for these
131 file types. Note the processes UID still need to have DAC permissions.

200 SELinux requires files to have an extended attribute to define the file
201 type.
202
203 You can see the context of a file using the -Z option to ls
204
205 Policy governs the access confined processes have to these files.
206 SELinux ypxfr policy is very flexible allowing users to setup their
207 ypxfr processes in as secure a method as possible.
208
209 STANDARD FILE CONTEXT
210
211 SELinux defines the file context types for the ypxfr, if you wanted to
212 store files with these types in a diffent paths, you need to execute
213 the semanage command to sepecify alternate labeling and then use
214 restorecon to put the labels on disk.
215
216 semanage fcontext -a -t ypxfr_var_run_t '/srv/myypxfr_content(/.*)?'
217 restorecon -R -v /srv/myypxfr_content
218
219 Note: SELinux often uses regular expressions to specify labels that
220 match multiple files.
221
222 The following file types are defined for ypxfr:
223
224
225
226 ypxfr_exec_t
227
228 - Set files with the ypxfr_exec_t type, if you want to transition an
229 executable to the ypxfr_t domain.
230
231
232 Paths:
233 /usr/lib/yp/ypxfr, /usr/lib64/yp/ypxfr, /usr/sbin/rpc.ypxfrd
234
235
236 ypxfr_var_run_t
237
238 - Set files with the ypxfr_var_run_t type, if you want to store the
239 ypxfr files under the /run or /var/run directory.
240
241
242
243 Note: File context can be temporarily modified with the chcon command.
244 If you want to permanently change the file context you need to use the
245 semanage fcontext command. This will modify the SELinux labeling data‐
246 base. You will need to use restorecon to apply the labels.
247
248
250 semanage fcontext can also be used to manipulate default file context
251 mappings.
252
253 semanage permissive can also be used to manipulate whether or not a
254 process type is permissive.
255
256 semanage module can also be used to enable/disable/install/remove pol‐
257 icy modules.
258
259 semanage boolean can also be used to manipulate the booleans
260
261
262 system-config-selinux is a GUI tool available to customize SELinux pol‐
263 icy settings.
