6 rpcd_selinux - Security Enhanced Linux Policy for the rpcd processes
7
9 Security-Enhanced Linux secures the rpcd processes via flexible manda‐
10 tory access control.
11
12 The rpcd processes execute with the rpcd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep rpcd_t
19
20
21
23 The rpcd_t SELinux type can be entered via the rpcd_exec_t file type.
24
25 The default entrypoint paths for the rpcd_t domain are the following:
26
27 /sbin/rpc..*, /usr/sbin/rpc..*, /sbin/sm-notify, /usr/sbin/nfsdcld,
28 /usr/sbin/sm-notify, /usr/sbin/rpc.idmapd, /usr/sbin/rpc.rquotad
29
31 SELinux defines process types (domains) for each process running on the
32 system
33
34 You can see the context of a process using the -Z option to ps
35
36 Policy governs the access confined processes have to files. SELinux
37 rpcd policy is very flexible allowing users to setup their rpcd pro‐
38 cesses in as secure a method as possible.
39
40 The following process types are defined for rpcd:
41
42 rpcd_t
43
44 Note: semanage permissive -a rpcd_t can be used to make the process
45 type rpcd_t permissive. SELinux does not deny access to permissive
46 process types, but the AVC (SELinux denials) messages are still gener‐
47 ated.
48
49
51 SELinux policy is customizable based on least access required. rpcd
52 policy is extremely flexible and has several booleans that allow you to
53 manipulate the policy and run rpcd with the tightest access possible.
54
55
56
57 If you want to allow rpcd_t to manage fuse files, you must turn on the
58 rpcd_use_fusefs boolean. Disabled by default.
59
60 setsebool -P rpcd_use_fusefs 1
61
62
63
64 If you want to dontaudit all daemons scheduling requests (setsched,
65 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
66 Enabled by default.
67
68 setsebool -P daemons_dontaudit_scheduling 1
69
70
71
72 If you want to allow all domains to execute in fips_mode, you must turn
73 on the fips_mode boolean. Enabled by default.
74
75 setsebool -P fips_mode 1
76
77
78
79 If you want to allow system to run with NIS, you must turn on the
80 nis_enabled boolean. Disabled by default.
81
82 setsebool -P nis_enabled 1
83
84
85
87 The SELinux process type rpcd_t can manage files labeled with the fol‐
88 lowing file types. The paths listed are the default paths for these
89 file types. Note the processes UID still need to have DAC permissions.

182 SELinux requires files to have an extended attribute to define the file
183 type.
184
185 You can see the context of a file using the -Z option to ls
186
187 Policy governs the access confined processes have to these files.
188 SELinux rpcd policy is very flexible allowing users to setup their rpcd
189 processes in as secure a method as possible.
190
191 EQUIVALENCE DIRECTORIES
192
193
194 rpcd policy stores data with multiple different file context types un‐
195 der the /var/run/rpc.statd directory. If you would like to store the
196 data in a different directory you can use the semanage command to cre‐
197 ate an equivalence mapping. If you wanted to store this data under the
198 /srv directory you would execute the following command:
199
200 semanage fcontext -a -e /var/run/rpc.statd /srv/rpc.statd
201 restorecon -R -v /srv/rpc.statd
202
203 STANDARD FILE CONTEXT
204
205 SELinux defines the file context types for the rpcd, if you wanted to
206 store files with these types in a different paths, you need to execute
207 the semanage command to specify alternate labeling and then use re‐
208 storecon to put the labels on disk.
209
210 semanage fcontext -a -t rpcd_var_run_t '/srv/rpcd/content(/.*)?'
211 restorecon -R -v /srv/myrpcd_content
212
213 Note: SELinux often uses regular expressions to specify labels that
214 match multiple files.
215
216 The following file types are defined for rpcd:
217
218
219
220 rpcd_exec_t
221
222 - Set files with the rpcd_exec_t type, if you want to transition an ex‐
223 ecutable to the rpcd_t domain.
224
225
226 Paths:
227 /sbin/rpc..*, /usr/sbin/rpc..*, /sbin/sm-notify, /usr/sbin/nfsd‐
228 cld, /usr/sbin/sm-notify, /usr/sbin/rpc.idmapd,
229 /usr/sbin/rpc.rquotad
230
231
232 rpcd_initrc_exec_t
233
234 - Set files with the rpcd_initrc_exec_t type, if you want to transition
235 an executable to the rpcd_initrc_t domain.
236
237
238 Paths:
239 /etc/rc.d/init.d/nfslock, /etc/rc.d/init.d/rpcidmapd
240
241
242 rpcd_lock_t
243
244 - Set files with the rpcd_lock_t type, if you want to treat the files
245 as rpcd lock data, stored under the /var/lock directory
246
247
248
249 rpcd_unit_file_t
250
251 - Set files with the rpcd_unit_file_t type, if you want to treat the
252 files as rpcd unit content.
253
254
255
256 rpcd_var_run_t
257
258 - Set files with the rpcd_var_run_t type, if you want to store the rpcd
259 files under the /run or /var/run directory.
260
261
262 Paths:
263 /var/run/sm-notify.*, /var/run/rpc.statd(/.*)?,
264 /var/run/rpc.statd.pid
265
266
267 Note: File context can be temporarily modified with the chcon command.
268 If you want to permanently change the file context you need to use the
269 semanage fcontext command. This will modify the SELinux labeling data‐
270 base. You will need to use restorecon to apply the labels.
271
272
274 semanage fcontext can also be used to manipulate default file context
275 mappings.
276
277 semanage permissive can also be used to manipulate whether or not a
278 process type is permissive.
279
280 semanage module can also be used to enable/disable/install/remove pol‐
281 icy modules.
282
283 semanage boolean can also be used to manipulate the booleans
284
285
286 system-config-selinux is a GUI tool available to customize SELinux pol‐
287 icy settings.
