NAME

6       dcerpcd_selinux  -  Security Enhanced Linux Policy for the dcerpcd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  dcerpcd  processes  via  flexible
11       mandatory access control.
12
13       The  dcerpcd processes execute with the dcerpcd_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 dcerpcd_t
20
21
22

ENTRYPOINTS

24       The  dcerpcd_t  SELinux type can be entered via the dcerpcd_exec_t file
25       type.
26
27       The default entrypoint paths for the dcerpcd_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/dcerpcd, /opt/likewise/sbin/dcerpcd
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       dcerpcd  policy  is very flexible allowing users to setup their dcerpcd
40       processes in as secure a method as possible.
41
42       The following process types are defined for dcerpcd:
43
44       dcerpcd_t
45
46       Note: semanage permissive -a dcerpcd_t can be used to make the  process
47       type  dcerpcd_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux policy is customizable based on least access required.  dcerpcd
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run dcerpcd with the tightest access possi‐
56       ble.
57
58
59
60       If you want to allow all daemons to write corefiles to /, you must turn
61       on the daemons_dump_core boolean. Disabled by default.

85
86
87
88       If you want to deny any process from ptracing or  debugging  any  other
89       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
90       default.
91
92       setsebool -P deny_ptrace 1
93
94
95
96       If you want to allow any process  to  mmap  any  file  on  system  with

120       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
121       default.
122
123       setsebool -P domain_kernel_load_modules 1

MANAGED FILES

142       The  SELinux  process  type dcerpcd_t can manage files labeled with the
143       following file types.  The paths listed are the default paths for these
144       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

191       SELinux requires files to have an extended attribute to define the file
192       type.
193
194       You can see the context of a file using the -Z option to ls
195
196       Policy governs the access  confined  processes  have  to  these  files.
197       SELinux  dcerpcd  policy is very flexible allowing users to setup their
198       dcerpcd processes in as secure a method as possible.
199
200       STANDARD FILE CONTEXT
201
202       SELinux defines the file context types for the dcerpcd, if  you  wanted
203       to store files with these types in a diffent paths, you need to execute
204       the semanage command  to  sepecify  alternate  labeling  and  then  use
205       restorecon to put the labels on disk.
206
207       semanage   fcontext  -a  -t  dcerpcd_var_socket_t  '/srv/mydcerpcd_con‐
208       tent(/.*)?'
209       restorecon -R -v /srv/mydcerpcd_content
210
211       Note: SELinux often uses regular expressions  to  specify  labels  that
212       match multiple files.
213
214       The following file types are defined for dcerpcd:
215
216
217
218       dcerpcd_exec_t
219
220       -  Set files with the dcerpcd_exec_t type, if you want to transition an
221       executable to the dcerpcd_t domain.
222
223
224       Paths:
225            /usr/sbin/dcerpcd, /opt/likewise/sbin/dcerpcd
226
227
228       dcerpcd_var_lib_t
229
230       - Set files with the dcerpcd_var_lib_t type, if you want to  store  the
231       dcerpcd files under the /var/lib directory.
232
233
234       Paths:
235            /var/lib/likewise/run/rpcdep.dat,               /var/lib/likewise-
236            open/run/rpcdep.dat
237
238
239       dcerpcd_var_run_t
240
241       - Set files with the dcerpcd_var_run_t type, if you want to  store  the
242       dcerpcd files under the /run or /var/run directory.
243
244
245
246       dcerpcd_var_socket_t
247
248       -  Set  files  with the dcerpcd_var_socket_t type, if you want to treat
249       the files as dcerpcd var socket data.
250
251
252       Paths:
253            /var/lib/likewise/rpc/epmapper,  /var/lib/likewise-open/rpc/epmap‐
254            per
255
256
257       Note:  File context can be temporarily modified with the chcon command.
258       If you want to permanently change the file context you need to use  the
259       semanage fcontext command.  This will modify the SELinux labeling data‐
260       base.  You will need to use restorecon to apply the labels.
261
262

COMMANDS

264       semanage fcontext can also be used to manipulate default  file  context
265       mappings.
266
267       semanage  permissive  can  also  be used to manipulate whether or not a
268       process type is permissive.
269
270       semanage module can also be used to enable/disable/install/remove  pol‐
271       icy modules.
272
273       semanage boolean can also be used to manipulate the booleans
274
275
276       system-config-selinux is a GUI tool available to customize SELinux pol‐
277       icy settings.
