NAME

6       mono_selinux - Security Enhanced Linux Policy for the mono processes
7

DESCRIPTION

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

21

ENTRYPOINTS

23       The mono_t SELinux type can be entered via the file_type,  unlabeled_t,
24       proc_type,  filesystem_type,  mono_exec_t,  mtrr_device_t,  sysctl_type
25       file types.
26
27       The default entrypoint paths for the mono_t domain are the following:
28
29       all files on the system, /usr/bin/mono.*, /dev/cpu/mtrr
30

PROCESS TYPES

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

BOOLEANS

52       SELinux policy is customizable based on least  access  required.   mono
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run mono with the tightest access possible.
55
56
57
58       If you want to allow all daemons the ability to  read/write  terminals,
59       you  must  turn  on  the  allow_daemons_use_tty  boolean.  Disabled  by
60       default.
61
62       setsebool -P allow_daemons_use_tty 1
63
64
65
66       If you want to allow all domains to use other domains file descriptors,
67       you must turn on the allow_domain_fd_use boolean. Enabled by default.
68
69       setsebool -P allow_domain_fd_use 1
70
71
72
73       If  you  want to allow unconfined executables to make their heap memory
74       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
75       badly  coded  executable, but could indicate an attack. This executable
76       should be reported in bugzilla, you must  turn  on  the  allow_execheap
77       boolean. Disabled by default.
78
79       setsebool -P allow_execheap 1
80
81
82
83       If  you  want to allow unconfined executables to map a memory region as
84       both executable and writable, this  is  dangerous  and  the  executable
85       should  be  reported  in  bugzilla), you must turn on the allow_execmem
86       boolean. Enabled by default.
87
88       setsebool -P allow_execmem 1
89
90
91
92       If you want to  allow  all  unconfined  executables  to  use  libraries
93       requiring  text  relocation  that are not labeled textrel_shlib_t), you
94       must turn on the allow_execmod boolean. Enabled by default.
95
96       setsebool -P allow_execmod 1
97
98
99
100       If you want to allow unconfined executables to make  their  stack  exe‐
101       cutable.   This  should  never, ever be necessary. Probably indicates a
102       badly coded executable, but could indicate an attack.  This  executable
103       should  be  reported in bugzilla), you must turn on the allow_execstack
104       boolean. Enabled by default.
105
106       setsebool -P allow_execstack 1
107
108
109
110       If you want to allow sysadm to debug or ptrace all processes, you  must
111       turn on the allow_ptrace boolean. Disabled by default.
112
113       setsebool -P allow_ptrace 1
114
115
116
117       If  you  want to allow all domains to have the kernel load modules, you
118       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
119       default.
120
121       setsebool -P domain_kernel_load_modules 1
122
123
124
125       If you want to allow all domains to execute in fips_mode, you must turn
126       on the fips_mode boolean. Enabled by default.
127
128       setsebool -P fips_mode 1
129
130
131
132       If you want to enable reading of urandom for all domains, you must turn
133       on the global_ssp boolean. Disabled by default.
134
135       setsebool -P global_ssp 1
136
137
138
139       If  you  want to allow certain domains to map low memory in the kernel,
140       you must turn on the mmap_low_allowed boolean. Disabled by default.
141
142       setsebool -P mmap_low_allowed 1
143
144
145
146       If you want to boolean to determine whether the system permits  loading
147       policy,  setting enforcing mode, and changing boolean values.  Set this
148       to true and you have to reboot to set it back, you  must  turn  on  the
149       secure_mode_policyload boolean. Disabled by default.
150
151       setsebool -P secure_mode_policyload 1
152
153
154
155       If you want to support X userspace object manager, you must turn on the
156       xserver_object_manager boolean. Disabled by default.
157
158       setsebool -P xserver_object_manager 1

PORT TYPES

163       SELinux defines port types to represent TCP and UDP ports.
164
165       You can see the types associated with a port  by  using  the  following
166       command:
167
168       semanage port -l
169
170
171       Policy  governs  the  access  confined  processes  have to these ports.
172       SELinux mono policy is very flexible allowing users to setup their mono
173       processes in as secure a method as possible.
174
175       The following port types are defined for mono:
176
177
178       monopd_port_t
179
180
181
182       Default Defined Ports:
183                 tcp 1234
184

MANAGED FILES

186       The  SELinux process type mono_t can manage files labeled with the fol‐
187       lowing file types.  The paths listed are the default  paths  for  these
188       file types.  Note the processes UID still need to have DAC permissions.
189
190       file_type
191
192            all files on the system
193
194

FILE CONTEXTS

196       SELinux requires files to have an extended attribute to define the file
197       type.
198
199       You can see the context of a file using the -Z option to ls
200
201       Policy governs the access  confined  processes  have  to  these  files.
202       SELinux mono policy is very flexible allowing users to setup their mono
203       processes in as secure a method as possible.
204
205       The following file types are defined for mono:
206
207
208
209       mono_exec_t
210
211       - Set files with the mono_exec_t type, if you  want  to  transition  an
212       executable to the mono_t domain.
213
214
215
216       Note:  File context can be temporarily modified with the chcon command.
217       If you want to permanently change the file context you need to use  the
218       semanage fcontext command.  This will modify the SELinux labeling data‐
219       base.  You will need to use restorecon to apply the labels.
220
221

COMMANDS

223       semanage fcontext can also be used to manipulate default  file  context
224       mappings.
225
226       semanage  permissive  can  also  be used to manipulate whether or not a
227       process type is permissive.
228
229       semanage module can also be used to enable/disable/install/remove  pol‐
230       icy modules.
231
232       semanage port can also be used to manipulate the port definitions
233
234       semanage boolean can also be used to manipulate the booleans
235
236
237       system-config-selinux is a GUI tool available to customize SELinux pol‐
238       icy settings.
