NAME

6       sge_shepherd_selinux - Security Enhanced Linux Policy for the sge_shep‐
7       herd processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the sge_shepherd processes via flexible
11       mandatory access control.
12
13       The  sge_shepherd  processes  execute  with  the sge_shepherd_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 sge_shepherd_t
20

22

ENTRYPOINTS

24       The  sge_shepherd_t  SELinux  type  can  be  entered  via the sge_shep‐
25       herd_exec_t file type.
26
27       The default entrypoint paths for the sge_shepherd_t domain are the fol‐
28       lowing:
29
30       /usr/bin/sge_shepherd
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_shepherd  policy  is  very  flexible  allowing users to setup their
40       sge_shepherd processes in as secure a method as possible.
41
42       The following process types are defined for sge_shepherd:
43
44       sge_shepherd_t
45
46       Note: semanage permissive -a sge_shepherd_t can be  used  to  make  the
47       process type sge_shepherd_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_shepherd policy is extremely flexible and has several booleans that
55       allow you to manipulate the policy and run sge_shepherd with the tight‐
56       est access possible.
57
58
59
60       If you want to deny user domains applications to map a memory region as
61       both  executable  and  writable,  this  is dangerous and the executable
62       should be reported in bugzilla, you must turn on the deny_execmem bool‐
63       ean. Enabled by default.
64
65       setsebool -P deny_execmem 1
66
67
68
69       If you want to allow all domains to execute in fips_mode, you must turn
70       on the fips_mode boolean. Enabled by default.
71
72       setsebool -P fips_mode 1
73
74
75
76       If you want to control the ability to mmap a low area  of  the  address
77       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
78       the mmap_low_allowed boolean. Disabled by default.
79
80       setsebool -P mmap_low_allowed 1
81
82
83
84       If you want to allow confined applications to use nscd  shared  memory,
85       you must turn on the nscd_use_shm boolean. Disabled by default.
86
87       setsebool -P nscd_use_shm 1
88
89
90
91       If  you  want  to  disable  kernel module loading, you must turn on the
92       secure_mode_insmod boolean. Enabled by default.
93
94       setsebool -P secure_mode_insmod 1
95
96
97
98       If you want to allow unconfined executables to make their  heap  memory
99       executable.   Doing  this  is  a  really bad idea. Probably indicates a
100       badly coded executable, but could indicate an attack.  This  executable
101       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
102       uxuser_execheap boolean. Disabled by default.
103
104       setsebool -P selinuxuser_execheap 1
105
106
107
108       If you want to allow unconfined executables to make  their  stack  exe‐
109       cutable.   This  should  never, ever be necessary. Probably indicates a
110       badly coded executable, but could indicate an attack.  This  executable
111       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
112       stack boolean. Enabled by default.
113
114       setsebool -P selinuxuser_execstack 1

MANAGED FILES

119       The SELinux process type sge_shepherd_t can manage files  labeled  with
120       the  following  file types.  The paths listed are the default paths for
121       these file types.  Note the processes UID still need to have  DAC  per‐
122       missions.
123
124       file_type
125
126            all files on the system
127
128

FILE CONTEXTS

130       SELinux requires files to have an extended attribute to define the file
131       type.
132
133       You can see the context of a file using the -Z option to ls
134
135       Policy governs the access  confined  processes  have  to  these  files.
136       SELinux  sge_shepherd  policy  is very flexible allowing users to setup
137       their sge_shepherd processes in as secure a method as possible.
138
139       The following file types are defined for sge_shepherd:
140
141
142
143       sge_shepherd_exec_t
144
145       - Set files with the sge_shepherd_exec_t type, if you want  to  transi‐
146       tion an executable to the sge_shepherd_t domain.
147
148
149
150       Note:  File context can be temporarily modified with the chcon command.
151       If you want to permanently change the file context you need to use  the
152       semanage fcontext command.  This will modify the SELinux labeling data‐
153       base.  You will need to use restorecon to apply the labels.
154
155

COMMANDS

157       semanage fcontext can also be used to manipulate default  file  context
158       mappings.
159
160       semanage  permissive  can  also  be used to manipulate whether or not a
161       process type is permissive.
162
163       semanage module can also be used to enable/disable/install/remove  pol‐
164       icy modules.
165
166       semanage boolean can also be used to manipulate the booleans
167
168
169       system-config-selinux is a GUI tool available to customize SELinux pol‐
170       icy settings.
