NAME

6       ricci_modcluster_selinux  -  Security  Enhanced  Linux  Policy  for the
7       ricci_modcluster processes
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  ricci_modcluster  processes  via
11       flexible mandatory access control.
12
13       The  ricci_modcluster  processes  execute  with  the ricci_modcluster_t
14       SELinux type. You can check if you have these processes running by exe‐
15       cuting the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep ricci_modcluster_t
20
21
22

ENTRYPOINTS

24       The  ricci_modcluster_t  SELinux type can be entered via the file_type,
25       unlabeled_t, proc_type,  filesystem_type,  mtrr_device_t,  sysctl_type,
26       ricci_modcluster_exec_t file types.
27
28       The  default entrypoint paths for the ricci_modcluster_t domain are the
29       following:
30
31       all files on the system, /dev/cpu/mtrr, /usr/libexec/modcluster
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       ricci_modcluster policy is very flexible allowing users to setup  their
41       ricci_modcluster processes in as secure a method as possible.
42
43       The following process types are defined for ricci_modcluster:
44
45       ricci_modclusterd_t, ricci_modcluster_t
46
47       Note: semanage permissive -a ricci_modcluster_t can be used to make the
48       process type  ricci_modcluster_t  permissive.  SELinux  does  not  deny
49       access  to permissive process types, but the AVC (SELinux denials) mes‐
50       sages are still generated.
51
52

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       ricci_modcluster  policy is extremely flexible and has several booleans
56       that allow you to manipulate the policy and run  ricci_modcluster  with
57       the tightest 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  disable  transitions to insmod, you must turn on the
142       secure_mode_insmod boolean. Disabled by default.
143
144       setsebool -P secure_mode_insmod 1
145
146
147
148       If you want to boolean to determine whether the system permits  loading
149       policy,  setting enforcing mode, and changing boolean values.  Set this
150       to true and you have to reboot to set it back, you  must  turn  on  the
151       secure_mode_policyload boolean. Disabled by default.
152
153       setsebool -P secure_mode_policyload 1
154
155
156
157       If you want to support X userspace object manager, you must turn on the
158       xserver_object_manager boolean. Disabled by default.
159
160       setsebool -P xserver_object_manager 1
161
162
163

PORT TYPES

165       SELinux defines port types to represent TCP and UDP ports.
166
167       You can see the types associated with a port  by  using  the  following
168       command:
169
170       semanage port -l
171
172
173       Policy  governs  the  access  confined  processes  have to these ports.
174       SELinux ricci_modcluster policy is very flexible allowing users to set‐
175       up their ricci_modcluster processes in as secure a method as possible.
176
177       The following port types are defined for ricci_modcluster:
178
179
180       ricci_modcluster_port_t
181
182
183
184       Default Defined Ports:
185                 tcp 16851
186                 udp 16851
187

MANAGED FILES

189       The  SELinux  process  type ricci_modcluster_t can manage files labeled
190       with the following file types.  The paths listed are the default  paths
191       for  these  file  types.  Note the processes UID still need to have DAC
192       permissions.
193
194       file_type
195
196            all files on the system
197
198

FILE CONTEXTS

200       SELinux requires files to have an extended attribute to define the file
201       type.
202
203       You can see the context of a file using the -Z option to ls
204
205       Policy  governs  the  access  confined  processes  have to these files.
206       SELinux ricci_modcluster policy is very flexible allowing users to set‐
207       up their ricci_modcluster processes in as secure a method as possible.
208
209       STANDARD FILE CONTEXT
210
211       SELinux defines the file context types for the ricci_modcluster, if you
212       wanted to store files with these types in a diffent paths, you need  to
213       execute  the  semanage  command to sepecify alternate labeling and then
214       use restorecon to put the labels on disk.
215
216       semanage fcontext -a  -t  ricci_modclusterd_tmpfs_t  '/srv/myricci_mod‐
217       cluster_content(/.*)?'
218       restorecon -R -v /srv/myricci_modcluster_content
219
220       Note:  SELinux  often  uses  regular expressions to specify labels that
221       match multiple files.
222
223       The following file types are defined for ricci_modcluster:
224
225
226
227       ricci_modcluster_exec_t
228
229       - Set files with the ricci_modcluster_exec_t type, if you want to tran‐
230       sition an executable to the ricci_modcluster_t domain.
231
232
233
234       ricci_modcluster_var_lib_t
235
236       -  Set  files  with the ricci_modcluster_var_lib_t type, if you want to
237       store the ricci modcluster files under the /var/lib directory.
238
239
240
241       ricci_modcluster_var_log_t
242
243       - Set files with the ricci_modcluster_var_log_t type, if  you  want  to
244       treat  the  data as ricci modcluster var log data, usually stored under
245       the /var/log directory.
246
247
248
249       ricci_modcluster_var_run_t
250
251       - Set files with the ricci_modcluster_var_run_t type, if  you  want  to
252       store the ricci modcluster files under the /run or /var/run directory.
253
254
255       Paths:
256            /var/run/clumond.sock, /var/run/modclusterd.pid
257
258
259       ricci_modclusterd_exec_t
260
261       -  Set  files  with  the  ricci_modclusterd_exec_t type, if you want to
262       transition an executable to the ricci_modclusterd_t domain.
263
264
265
266       ricci_modclusterd_tmpfs_t
267
268       - Set files with the ricci_modclusterd_tmpfs_t type,  if  you  want  to
269       store ricci modclusterd files on a tmpfs file system.
270
271
272
273       Note:  File context can be temporarily modified with the chcon command.
274       If you want to permanently change the file context you need to use  the
275       semanage fcontext command.  This will modify the SELinux labeling data‐
276       base.  You will need to use restorecon to apply the labels.
277
278

COMMANDS

280       semanage fcontext can also be used to manipulate default  file  context
281       mappings.
282
283       semanage  permissive  can  also  be used to manipulate whether or not a
284       process type is permissive.
285
286       semanage module can also be used to enable/disable/install/remove  pol‐
287       icy modules.
288
289       semanage port can also be used to manipulate the port definitions
290
291       semanage boolean can also be used to manipulate the booleans
292
293
294       system-config-selinux is a GUI tool available to customize SELinux pol‐
295       icy settings.
