6 sge_shepherd_selinux - Security Enhanced Linux Policy for the sge_shep‐
7 herd processes
8
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
21
22
24 The sge_shepherd_t SELinux type can be entered via the file_type,
25 sge_shepherd_exec_t, unlabeled_t, proc_type, filesystem_type,
26 mtrr_device_t, sysctl_type file types.
27
28 The default entrypoint paths for the sge_shepherd_t domain are the fol‐
29 lowing:
30
31 all files on the system, /usr/bin/sge_shepherd, /dev/cpu/mtrr
32
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 sge_shepherd policy is very flexible allowing users to setup their
41 sge_shepherd processes in as secure a method as possible.
42
43 The following process types are defined for sge_shepherd:
44
45 sge_shepherd_t
46
47 Note: semanage permissive -a sge_shepherd_t can be used to make the
48 process type sge_shepherd_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
52
54 SELinux policy is customizable based on least access required.
55 sge_shepherd policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run sge_shepherd with the tight‐
57 est access possible.
58
59
60
61 If you want to allow all domains to use other domains file descriptors,
62 you must turn on the allow_domain_fd_use boolean. Enabled by default.
63
64 setsebool -P allow_domain_fd_use 1
65
66
67
68 If you want to allow unconfined executables to make their heap memory
69 executable. Doing this is a really bad idea. Probably indicates a
70 badly coded executable, but could indicate an attack. This executable
71 should be reported in bugzilla, you must turn on the allow_execheap
72 boolean. Disabled by default.
73
74 setsebool -P allow_execheap 1
75
76
77
78 If you want to allow unconfined executables to map a memory region as
79 both executable and writable, this is dangerous and the executable
80 should be reported in bugzilla), you must turn on the allow_execmem
81 boolean. Enabled by default.
82
83 setsebool -P allow_execmem 1
84
85
86
87 If you want to allow all unconfined executables to use libraries
88 requiring text relocation that are not labeled textrel_shlib_t), you
89 must turn on the allow_execmod boolean. Enabled by default.
90
91 setsebool -P allow_execmod 1
92
93
94
95 If you want to allow unconfined executables to make their stack exe‐
96 cutable. This should never, ever be necessary. Probably indicates a
97 badly coded executable, but could indicate an attack. This executable
98 should be reported in bugzilla), you must turn on the allow_execstack
99 boolean. Enabled by default.
100
101 setsebool -P allow_execstack 1
102
103
104
105 If you want to allow sysadm to debug or ptrace all processes, you must
106 turn on the allow_ptrace boolean. Disabled by default.
107
108 setsebool -P allow_ptrace 1
109
110
111
112 If you want to allow all domains to have the kernel load modules, you
113 must turn on the domain_kernel_load_modules boolean. Disabled by
114 default.
115
116 setsebool -P domain_kernel_load_modules 1
117
118
119
120 If you want to allow all domains to execute in fips_mode, you must turn
121 on the fips_mode boolean. Enabled by default.
122
123 setsebool -P fips_mode 1
124
125
126
127 If you want to enable reading of urandom for all domains, you must turn
128 on the global_ssp boolean. Disabled by default.
129
130 setsebool -P global_ssp 1
131
132
133
134 If you want to allow certain domains to map low memory in the kernel,
135 you must turn on the mmap_low_allowed boolean. Disabled by default.
136
137 setsebool -P mmap_low_allowed 1
138
139
140
141 If you want to boolean to determine whether the system permits loading
142 policy, setting enforcing mode, and changing boolean values. Set this
143 to true and you have to reboot to set it back, you must turn on the
144 secure_mode_policyload boolean. Disabled by default.
145
146 setsebool -P secure_mode_policyload 1
147
148
149
150 If you want to allow sge to connect to the network using any TCP port,
151 you must turn on the sge_domain_can_network_connect boolean. Disabled
152 by default.
153
154 setsebool -P sge_domain_can_network_connect 1
155
156
157
158 If you want to allow sge to access nfs file systems, you must turn on
159 the sge_use_nfs boolean. Disabled by default.
160
161 setsebool -P sge_use_nfs 1
162
163
164
165 If you want to support X userspace object manager, you must turn on the
166 xserver_object_manager boolean. Disabled by default.
167
168 setsebool -P xserver_object_manager 1
169
170
171
173 The SELinux process type sge_shepherd_t can manage files labeled with
174 the following file types. The paths listed are the default paths for
175 these file types. Note the processes UID still need to have DAC per‐
176 missions.
177
178 file_type
179
180 all files on the system
181
182
184 SELinux requires files to have an extended attribute to define the file
185 type.
186
187 You can see the context of a file using the -Z option to ls
188
189 Policy governs the access confined processes have to these files.
190 SELinux sge_shepherd policy is very flexible allowing users to setup
191 their sge_shepherd processes in as secure a method as possible.
192
193 The following file types are defined for sge_shepherd:
194
195
196
197 sge_shepherd_exec_t
198
199 - Set files with the sge_shepherd_exec_t type, if you want to transi‐
200 tion an executable to the sge_shepherd_t domain.
201
202
203
204 Note: File context can be temporarily modified with the chcon command.
205 If you want to permanently change the file context you need to use the
206 semanage fcontext command. This will modify the SELinux labeling data‐
207 base. You will need to use restorecon to apply the labels.
208
209
211 semanage fcontext can also be used to manipulate default file context
212 mappings.
213
214 semanage permissive can also be used to manipulate whether or not a
215 process type is permissive.
216
217 semanage module can also be used to enable/disable/install/remove pol‐
218 icy modules.
219
220 semanage boolean can also be used to manipulate the booleans
221
222
223 system-config-selinux is a GUI tool available to customize SELinux pol‐
224 icy settings.
