NAME

6       sge_execd_selinux  -  Security  Enhanced Linux Policy for the sge_execd
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the sge_execd  processes  via  flexible
11       mandatory access control.
12
13       The  sge_execd processes execute with the sge_execd_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep sge_execd_t
20
21
22

ENTRYPOINTS

24       The  sge_execd_t  SELinux  type can be entered via the sge_execd_exec_t
25       file type.
26
27       The default entrypoint paths for the sge_execd_t domain are the follow‐
28       ing:
29
30       /usr/bin/sge_execd
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       sge_execd  policy  is  very  flexible  allowing  users  to  setup their
40       sge_execd processes in as secure a method as possible.
41
42       The following process types are defined for sge_execd:
43
44       sge_execd_t
45
46       Note: semanage permissive -a  sge_execd_t  can  be  used  to  make  the
47       process  type  sge_execd_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       sge_execd policy is extremely flexible and has  several  booleans  that
55       allow  you to manipulate the policy and run sge_execd with the tightest
56       access possible.

MANAGED FILES

186       The  SELinux process type sge_execd_t can manage files labeled with the
187       following file types.  The paths listed are the default paths for these
188       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

237       SELinux requires files to have an extended attribute to define the file
238       type.
239
240       You can see the context of a file using the -Z option to ls
241
242       Policy governs the access  confined  processes  have  to  these  files.
243       SELinux sge_execd policy is very flexible allowing users to setup their
244       sge_execd processes in as secure a method as possible.
245
246       The following file types are defined for sge_execd:
247
248
249
250       sge_execd_exec_t
251
252       - Set files with the sge_execd_exec_t type, if you want  to  transition
253       an executable to the sge_execd_t domain.
254
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.
