6 condor_schedd_selinux - Security Enhanced Linux Policy for the con‐
7 dor_schedd processes
8
10 Security-Enhanced Linux secures the condor_schedd processes via flexi‐
11 ble mandatory access control.
12 The condor_schedd processes execute with the condor_schedd_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep condor_schedd_t
20
24 The condor_schedd_t SELinux type can be entered via the file_type, con‐
25 dor_schedd_exec_t, unlabeled_t, proc_type, filesystem_type,
26 mtrr_device_t, sysctl_type file types.
27 The default entrypoint paths for the condor_schedd_t domain are the
29 following:
30 all files on the system, /usr/sbin/condor_schedd, /dev/cpu/mtrr
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 condor_schedd policy is very flexible allowing users to setup their
41 condor_schedd processes in as secure a method as possible.
42 The following process types are defined for condor_schedd:
44 condor_schedd_t
46 Note: semanage permissive -a condor_schedd_t can be used to make the
48 process type condor_schedd_t permissive. SELinux does not deny access
49 to permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required. con‐
55 dor_schedd policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run condor_schedd with the
57 tightest access possible.

223 The SELinux process type condor_schedd_t can manage files labeled with
224 the following file types. The paths listed are the default paths for
225 these file types. Note the processes UID still need to have DAC per‐
226 missions.
227 file_type
229 all files on the system
231
234 SELinux requires files to have an extended attribute to define the file
235 type.
236 You can see the context of a file using the -Z option to ls
238 Policy governs the access confined processes have to these files.
240 SELinux condor_schedd policy is very flexible allowing users to setup
241 their condor_schedd processes in as secure a method as possible.
242 STANDARD FILE CONTEXT
244 SELinux defines the file context types for the condor_schedd, if you
246 wanted to store files with these types in a diffent paths, you need to
247 execute the semanage command to sepecify alternate labeling and then
248 use restorecon to put the labels on disk.
249 semanage fcontext -a -t condor_schedd_tmp_t '/srv/mycondor_schedd_con‐
251 tent(/.*)?'
252 restorecon -R -v /srv/mycondor_schedd_content
253 Note: SELinux often uses regular expressions to specify labels that
255 match multiple files.
256 The following file types are defined for condor_schedd:
258 condor_schedd_exec_t
262 - Set files with the condor_schedd_exec_t type, if you want to transi‐
264 tion an executable to the condor_schedd_t domain.
265 condor_schedd_tmp_t
269 - Set files with the condor_schedd_tmp_t type, if you want to store
271 condor schedd temporary files in the /tmp directories.
272 Note: File context can be temporarily modified with the chcon command.
276 If you want to permanently change the file context you need to use the
277 semanage fcontext command. This will modify the SELinux labeling data‐
278 base. You will need to use restorecon to apply the labels.
279
282 semanage fcontext can also be used to manipulate default file context
283 mappings.
284 semanage permissive can also be used to manipulate whether or not a
286 process type is permissive.
287 semanage module can also be used to enable/disable/install/remove pol‐
289 icy modules.
290 semanage boolean can also be used to manipulate the booleans
292 system-config-selinux is a GUI tool available to customize SELinux pol‐
295 icy settings.
