NAME

6       cfengine_execd_selinux   -  Security  Enhanced  Linux  Policy  for  the
7       cfengine_execd processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the cfengine_execd processes via flexi‐
11       ble mandatory access control.
12
13       The  cfengine_execd processes execute with the cfengine_execd_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 cfengine_execd_t
20
21
22

ENTRYPOINTS

24       The  cfengine_execd_t  SELinux  type  can be entered via the file_type,
25       unlabeled_t,   proc_type,    filesystem_type,    cfengine_execd_exec_t,
26       mtrr_device_t, sysctl_type file types.
27
28       The  default  entrypoint  paths for the cfengine_execd_t domain are the
29       following:
30
31       all files on the system, /usr/sbin/cf-execd, /dev/cpu/mtrr
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       cfengine_execd policy is very flexible allowing users  to  setup  their
41       cfengine_execd processes in as secure a method as possible.
42
43       The following process types are defined for cfengine_execd:
44
45       cfengine_execd_t
46
47       Note:  semanage  permissive -a cfengine_execd_t can be used to make the
48       process type cfengine_execd_t permissive. SELinux does not deny  access
49       to permissive process types, but the AVC (SELinux denials) messages are
50       still generated.
51
52

BOOLEANS

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

90       If you want to allow unconfined executables to make their  heap  memory
91       executable.   Doing  this  is  a  really bad idea. Probably indicates a
92       badly coded executable, but could indicate an attack.  This  executable
93       should  be  reported  in  bugzilla, you must turn on the allow_execheap
94       boolean. Disabled by default.

98
99
100       If you want to allow unconfined executables to map a memory  region  as
101       both  executable  and  writable,  this  is dangerous and the executable

114
115
116
117       If  you  want  to allow unconfined executables to make their stack exe‐
118       cutable.  This should never, ever be necessary.  Probably  indicates  a
119       badly  coded  executable, but could indicate an attack. This executable
120       should be reported in bugzilla), you must turn on  the  allow_execstack
121       boolean. Enabled by default.

MANAGED FILES

215       The SELinux process type cfengine_execd_t can manage files labeled with
216       the  following  file types.  The paths listed are the default paths for
217       these file types.  Note the processes UID still need to have  DAC  per‐
218       missions.
219
220       file_type
221
222            all files on the system
223
224

FILE CONTEXTS

226       SELinux requires files to have an extended attribute to define the file
227       type.
228
229       You can see the context of a file using the -Z option to ls
230
231       Policy governs the access  confined  processes  have  to  these  files.
232       SELinux  cfengine_execd policy is very flexible allowing users to setup
233       their cfengine_execd processes in as secure a method as possible.
234
235       The following file types are defined for cfengine_execd:
236
237
238
239       cfengine_execd_exec_t
240
241       - Set files with the cfengine_execd_exec_t type, if you want to transi‐
242       tion an executable to the cfengine_execd_t domain.
243
244
245
246       Note:  File context can be temporarily modified with the chcon command.
247       If you want to permanently change the file context you need to use  the
248       semanage fcontext command.  This will modify the SELinux labeling data‐
249       base.  You will need to use restorecon to apply the labels.
250
251

COMMANDS

253       semanage fcontext can also be used to manipulate default  file  context
254       mappings.
255
256       semanage  permissive  can  also  be used to manipulate whether or not a
257       process type is permissive.
258
259       semanage module can also be used to enable/disable/install/remove  pol‐
260       icy modules.
261
262       semanage boolean can also be used to manipulate the booleans
263
264
265       system-config-selinux is a GUI tool available to customize SELinux pol‐
266       icy settings.
