6 condor_startd_selinux - Security Enhanced Linux Policy for the con‐
7 dor_startd processes
8
10 Security-Enhanced Linux secures the condor_startd processes via flexi‐
11 ble mandatory access control.
12
13 The condor_startd processes execute with the condor_startd_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep condor_startd_t
20
21
22
24 The condor_startd_t SELinux type can be entered via the con‐
25 dor_startd_exec_t file type.
26
27 The default entrypoint paths for the condor_startd_t domain are the
28 following:
29
30 /usr/sbin/condor_startd, /usr/sbin/condor_starter
31
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 condor_startd policy is very flexible allowing users to setup their
40 condor_startd processes in as secure a method as possible.
41
42 The following process types are defined for condor_startd:
43
44 condor_startd_t, condor_startd_ssh_t
45
46 Note: semanage permissive -a condor_startd_t can be used to make the
47 process type condor_startd_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. con‐
54 dor_startd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run condor_startd with the
56 tightest access possible.

245
247 The SELinux process type condor_startd_t can manage files labeled with
248 the following file types. The paths listed are the default paths for
249 these file types. Note the processes UID still need to have DAC per‐
250 missions.
251
252 file_type
253
254 all files on the system
255
256
258 SELinux requires files to have an extended attribute to define the file
259 type.
260
261 You can see the context of a file using the -Z option to ls
262
263 Policy governs the access confined processes have to these files.
264 SELinux condor_startd policy is very flexible allowing users to setup
265 their condor_startd processes in as secure a method as possible.
266
267 STANDARD FILE CONTEXT
268
269 SELinux defines the file context types for the condor_startd, if you
270 wanted to store files with these types in a diffent paths, you need to
271 execute the semanage command to sepecify alternate labeling and then
272 use restorecon to put the labels on disk.
273
274 semanage fcontext -a -t condor_startd_tmpfs_t '/srv/mycon‐
275 dor_startd_content(/.*)?'
276 restorecon -R -v /srv/mycondor_startd_content
277
278 Note: SELinux often uses regular expressions to specify labels that
279 match multiple files.
280
281 The following file types are defined for condor_startd:
282
283
284
285 condor_startd_exec_t
286
287 - Set files with the condor_startd_exec_t type, if you want to transi‐
288 tion an executable to the condor_startd_t domain.
289
290
291 Paths:
292 /usr/sbin/condor_startd, /usr/sbin/condor_starter
293
294
295 condor_startd_tmp_t
296
297 - Set files with the condor_startd_tmp_t type, if you want to store
298 condor startd temporary files in the /tmp directories.
299
300
301
302 condor_startd_tmpfs_t
303
304 - Set files with the condor_startd_tmpfs_t type, if you want to store
305 condor startd files on a tmpfs file system.
306
307
308
309 Note: File context can be temporarily modified with the chcon command.
310 If you want to permanently change the file context you need to use the
311 semanage fcontext command. This will modify the SELinux labeling data‐
312 base. You will need to use restorecon to apply the labels.
313
314
316 semanage fcontext can also be used to manipulate default file context
317 mappings.
318
319 semanage permissive can also be used to manipulate whether or not a
320 process type is permissive.
321
322 semanage module can also be used to enable/disable/install/remove pol‐
323 icy modules.
324
325 semanage boolean can also be used to manipulate the booleans
326
327
328 system-config-selinux is a GUI tool available to customize SELinux pol‐
329 icy settings.
