NAME

6       cinder_api_selinux  - Security Enhanced Linux Policy for the cinder_api
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

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

MANAGED FILES

113       The SELinux process type cinder_api_t can manage files labeled with the
114       following file types.  The paths listed are the default paths for these
115       file types.  Note the processes UID still need to have DAC permissions.
116
117       file_type
118
119            all files on the system
120
121

FILE CONTEXTS

123       SELinux requires files to have an extended attribute to define the file
124       type.
125
126       You can see the context of a file using the -Z option to ls
127
128       Policy  governs  the  access  confined  processes  have to these files.
129       SELinux cinder_api policy is very  flexible  allowing  users  to  setup
130       their cinder_api processes in as secure a method as possible.
131
132       STANDARD FILE CONTEXT
133
134       SELinux  defines  the  file  context  types  for the cinder_api, if you
135       wanted to store files with these types in a different paths,  you  need
136       to  execute the semanage command to specify alternate labeling and then
137       use restorecon to put the labels on disk.
138
139       semanage  fcontext  -a   -t   cinder_api_exec_t   '/srv/cinder_api/con‐
140       tent(/.*)?'
141       restorecon -R -v /srv/mycinder_api_content
142
143       Note:  SELinux  often  uses  regular expressions to specify labels that
144       match multiple files.
145
146       The following file types are defined for cinder_api:
147
148
149
150       cinder_api_exec_t
151
152       - Set files with the cinder_api_exec_t type, if you want to  transition
153       an executable to the cinder_api_t domain.
154
155
156
157       cinder_api_tmp_t
158
159       - Set files with the cinder_api_tmp_t type, if you want to store cinder
160       api temporary files in the /tmp directories.
161
162
163
164       cinder_api_unit_file_t
165
166       - Set files with the cinder_api_unit_file_t type, if you want to  treat
167       the files as cinder api unit content.
168
169
170
171       Note:  File context can be temporarily modified with the chcon command.
172       If you want to permanently change the file context you need to use  the
173       semanage fcontext command.  This will modify the SELinux labeling data‐
174       base.  You will need to use restorecon to apply the labels.
175
176

COMMANDS

178       semanage fcontext can also be used to manipulate default  file  context
179       mappings.
180
181       semanage  permissive  can  also  be used to manipulate whether or not a
182       process type is permissive.
183
184       semanage module can also be used to enable/disable/install/remove  pol‐
185       icy modules.
186
187       semanage boolean can also be used to manipulate the booleans
188
189
190       system-config-selinux is a GUI tool available to customize SELinux pol‐
191       icy settings.
