NAME

6       openvpn_unconfined_script_selinux  - Security Enhanced Linux Policy for
7       the openvpn_unconfined_script processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  openvpn_unconfined_script_t  SELinux  type  can be entered via the
25       file_type, shell_exec_t, unlabeled_t, proc_type, filesystem_type, open‐
26       vpn_unconfined_script_exec_t, mtrr_device_t, sysctl_type file types.
27
28       The default entrypoint paths for the openvpn_unconfined_script_t domain
29       are the following:
30
31       all files on the system, /bin/d?ash, /bin/zsh.*, /bin/ksh.*, /bin/sash,
32       /bin/tcsh,  /bin/yash,  /bin/mksh,  /bin/fish,  /bin/bash,  /bin/bash2,
33       /usr/bin/fish,    /sbin/nologin,    /usr/sbin/sesh,    /usr/sbin/smrsh,
34       /usr/bin/scponly,  /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-
35       shell,   /usr/libexec/git-core/git-shell,   /etc/openvpn/scripts(/.*)?,
36       /dev/cpu/mtrr

PROCESS TYPES

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

BOOLEANS

60       SELinux policy is customizable based on least access  required.   open‐
61       vpn_unconfined_script  policy  is  extremely  flexible  and has several
62       booleans that allow you to manipulate the policy and run openvpn_uncon‐
63       fined_script with the tightest access possible.
64
65
66
67       If you want to allow all domains to use other domains file descriptors,
68       you must turn on the allow_domain_fd_use boolean. Enabled by default.
69
70       setsebool -P allow_domain_fd_use 1
71
72
73
74       If you want to allow unconfined executables to make their  heap  memory
75       executable.   Doing  this  is  a  really bad idea. Probably indicates a
76       badly coded executable, but could indicate an attack.  This  executable
77       should  be  reported  in  bugzilla, you must turn on the allow_execheap
78       boolean. Disabled by default.
79
80       setsebool -P allow_execheap 1
81
82
83
84       If you want to allow unconfined executables to map a memory  region  as
85       both  executable  and  writable,  this  is dangerous and the executable
86       should be reported in bugzilla), you must  turn  on  the  allow_execmem
87       boolean. Enabled by default.
88
89       setsebool -P allow_execmem 1
90
91
92
93       If  you  want  to  allow  all  unconfined  executables to use libraries
94       requiring text relocation that are not  labeled  textrel_shlib_t),  you
95       must turn on the allow_execmod boolean. Enabled by default.
96
97       setsebool -P allow_execmod 1
98
99
100
101       If  you  want  to allow unconfined executables to make their stack exe‐
102       cutable.  This should never, ever be necessary.  Probably  indicates  a
103       badly  coded  executable, but could indicate an attack. This executable
104       should be reported in bugzilla), you must turn on  the  allow_execstack
105       boolean. Enabled by default.
106
107       setsebool -P allow_execstack 1
108
109
110
111       If  you want to allow sysadm to debug or ptrace all processes, you must
112       turn on the allow_ptrace boolean. Disabled by default.
113
114       setsebool -P allow_ptrace 1
115
116
117
118       If you want to allow all domains to have the kernel load  modules,  you
119       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
120       default.
121
122       setsebool -P domain_kernel_load_modules 1
123
124
125
126       If you want to allow all domains to execute in fips_mode, you must turn
127       on the fips_mode boolean. Enabled by default.
128
129       setsebool -P fips_mode 1
130
131
132
133       If you want to enable reading of urandom for all domains, you must turn
134       on the global_ssp boolean. Disabled by default.
135
136       setsebool -P global_ssp 1
137
138
139
140       If you want to allow certain domains to map low memory in  the  kernel,
141       you must turn on the mmap_low_allowed boolean. Disabled by default.
142
143       setsebool -P mmap_low_allowed 1
144
145
146
147       If  you  want to allow openvpn to run unconfined scripts, you must turn
148       on the openvpn_run_unconfined boolean. Disabled by default.
149
150       setsebool -P openvpn_run_unconfined 1
151
152
153
154       If you want to boolean to determine whether the system permits  loading
155       policy,  setting enforcing mode, and changing boolean values.  Set this
156       to true and you have to reboot to set it back, you  must  turn  on  the
157       secure_mode_policyload boolean. Disabled by default.
158
159       setsebool -P secure_mode_policyload 1
160
161
162
163       If you want to support X userspace object manager, you must turn on the
164       xserver_object_manager boolean. Disabled by default.
165
166       setsebool -P xserver_object_manager 1
167

MANAGED FILES

171       The SELinux process type openvpn_unconfined_script_t can  manage  files
172       labeled  with  the  following  file  types.   The  paths listed are the
173       default paths for these file types.  Note the processes UID still  need
174       to have DAC permissions.
175
176       file_type
177
178            all files on the system
179
180

FILE CONTEXTS

182       SELinux requires files to have an extended attribute to define the file
183       type.
184
185       You can see the context of a file using the -Z option to ls
186
187       Policy governs the access  confined  processes  have  to  these  files.
188       SELinux  openvpn_unconfined_script  policy  is  very  flexible allowing
189       users to setup their openvpn_unconfined_script processes in as secure a
190       method as possible.
191
192       The following file types are defined for openvpn_unconfined_script:
193
194
195
196       openvpn_unconfined_script_exec_t
197
198       - Set files with the openvpn_unconfined_script_exec_t type, if you want
199       to transition an executable to the openvpn_unconfined_script_t domain.
200
201
202
203       Note: File context can be temporarily modified with the chcon  command.
204       If  you want to permanently change the file context you need to use the
205       semanage fcontext command.  This will modify the SELinux labeling data‐
206       base.  You will need to use restorecon to apply the labels.
207
208

COMMANDS

210       semanage  fcontext  can also be used to manipulate default file context
211       mappings.
212
213       semanage permissive can also be used to manipulate  whether  or  not  a
214       process type is permissive.
215
216       semanage  module can also be used to enable/disable/install/remove pol‐
217       icy modules.
218
219       semanage boolean can also be used to manipulate the booleans
220
221
222       system-config-selinux is a GUI tool available to customize SELinux pol‐
223       icy settings.
