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 allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
72 The SELinux process type rpcd_t can manage files labeled with the fol‐
73 lowing file types. The paths listed are the default paths for these
74 file types. Note the processes UID still need to have DAC permissions.

149 SELinux requires files to have an extended attribute to define the file
150 type.
151
152 You can see the context of a file using the -Z option to ls
153
154 Policy governs the access confined processes have to these files.
155 SELinux rpcd policy is very flexible allowing users to setup their rpcd
156 processes in as secure a method as possible.
157
158 EQUIVALENCE DIRECTORIES
159
160
161 rpcd policy stores data with multiple different file context types
162 under the /var/run/rpc.statd directory. If you would like to store the
163 data in a different directory you can use the semanage command to cre‐
164 ate an equivalence mapping. If you wanted to store this data under the
165 /srv directory you would execute the following command:
166
167 semanage fcontext -a -e /var/run/rpc.statd /srv/rpc.statd
168 restorecon -R -v /srv/rpc.statd
169
170 STANDARD FILE CONTEXT
171
172 SELinux defines the file context types for the rpcd, if you wanted to
173 store files with these types in a diffent paths, you need to execute
174 the semanage command to sepecify alternate labeling and then use
175 restorecon to put the labels on disk.
176
177 semanage fcontext -a -t rpcd_unit_file_t '/srv/myrpcd_content(/.*)?'
178 restorecon -R -v /srv/myrpcd_content
179
180 Note: SELinux often uses regular expressions to specify labels that
181 match multiple files.
182
183 The following file types are defined for rpcd:
184
185
186
187 rpcd_exec_t
188
189 - Set files with the rpcd_exec_t type, if you want to transition an
190 executable to the rpcd_t domain.
191
192
193 Paths:
194 /sbin/rpc..*, /usr/sbin/rpc..*, /sbin/sm-notify, /usr/sbin/nfsd‐
195 cld, /usr/sbin/sm-notify, /usr/sbin/rpc.idmapd,
196 /usr/sbin/rpc.rquotad
197
198
199 rpcd_initrc_exec_t
200
201 - Set files with the rpcd_initrc_exec_t type, if you want to transition
202 an executable to the rpcd_initrc_t domain.
203
204
205 Paths:
206 /etc/rc.d/init.d/nfslock, /etc/rc.d/init.d/rpcidmapd
207
208
209 rpcd_lock_t
210
211 - Set files with the rpcd_lock_t type, if you want to treat the files
212 as rpcd lock data, stored under the /var/lock directory
213
214
215
216 rpcd_unit_file_t
217
218 - Set files with the rpcd_unit_file_t type, if you want to treat the
219 files as rpcd unit content.
220
221
222
223 rpcd_var_run_t
224
225 - Set files with the rpcd_var_run_t type, if you want to store the rpcd
226 files under the /run or /var/run directory.
227
228
229 Paths:
230 /var/run/sm-notify.*, /var/run/rpc.statd(/.*)?,
231 /var/run/rpc.statd.pid
232
233
234 Note: File context can be temporarily modified with the chcon command.
235 If you want to permanently change the file context you need to use the
236 semanage fcontext command. This will modify the SELinux labeling data‐
237 base. You will need to use restorecon to apply the labels.
238
239
241 semanage fcontext can also be used to manipulate default file context
242 mappings.
243
244 semanage permissive can also be used to manipulate whether or not a
245 process type is permissive.
246
247 semanage module can also be used to enable/disable/install/remove pol‐
248 icy modules.
249
250 semanage boolean can also be used to manipulate the booleans
251
252
253 system-config-selinux is a GUI tool available to customize SELinux pol‐
254 icy settings.
