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

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 deny user domains applications to map a memory region as
61       both  executable  and  writable,  this  is dangerous and the executable
62       should be reported in bugzilla, you must turn on the deny_execmem bool‐
63       ean. Enabled by default.
64
65       setsebool -P deny_execmem 1
66
67
68
69       If  you  want  to control the ability to mmap a low area of the address
70       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
71       the mmap_low_allowed boolean. Disabled by default.
72
73       setsebool -P mmap_low_allowed 1
74
75
76
77       If  you want to disable kernel module loading, you must turn on the se‐
78       cure_mode_insmod boolean. Enabled by default.
79
80       setsebool -P secure_mode_insmod 1
81
82
83
84       If you want to allow unconfined executables to make their  heap  memory
85       executable.   Doing  this  is  a  really bad idea. Probably indicates a
86       badly coded executable, but could indicate an attack.  This  executable
87       should  be  reported  in bugzilla, you must turn on the selinuxuser_ex‐
88       echeap boolean. Disabled by default.
89
90       setsebool -P selinuxuser_execheap 1
91
92
93
94       If you want to allow unconfined executables to make  their  stack  exe‐
95       cutable.   This  should  never, ever be necessary. Probably indicates a
96       badly coded executable, but could indicate an attack.  This  executable
97       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
98       stack boolean. Enabled by default.
99
100       setsebool -P selinuxuser_execstack 1

MANAGED FILES

105       The SELinux process type cinder_api_t can manage files labeled with the
106       following file types.  The paths listed are the default paths for these
107       file types.  Note the processes UID still need to have DAC permissions.
108
109       file_type
110
111            all files on the system
112
113

FILE CONTEXTS

115       SELinux requires files to have an extended attribute to define the file
116       type.
117
118       You can see the context of a file using the -Z option to ls
119
120       Policy  governs  the  access  confined  processes  have to these files.
121       SELinux cinder_api policy is very  flexible  allowing  users  to  setup
122       their cinder_api processes in as secure a method as possible.
123
124       STANDARD FILE CONTEXT
125
126       SELinux  defines  the  file  context  types  for the cinder_api, if you
127       wanted to store files with these types in a diffent paths, you need  to
128       execute  the  semanage  command to sepecify alternate labeling and then
129       use restorecon to put the labels on disk.
130
131       semanage  fcontext  -a  -t   cinder_api_tmp_t   '/srv/mycinder_api_con‐
132       tent(/.*)?'
133       restorecon -R -v /srv/mycinder_api_content
134
135       Note:  SELinux  often  uses  regular expressions to specify labels that
136       match multiple files.
137
138       The following file types are defined for cinder_api:
139
140
141
142       cinder_api_exec_t
143
144       - Set files with the cinder_api_exec_t type, if you want to  transition
145       an executable to the cinder_api_t domain.
146
147
148
149       cinder_api_tmp_t
150
151       - Set files with the cinder_api_tmp_t type, if you want to store cinder
152       api temporary files in the /tmp directories.
153
154
155
156       cinder_api_unit_file_t
157
158       - Set files with the cinder_api_unit_file_t type, if you want to  treat
159       the files as cinder api unit content.
160
161
162
163       Note:  File context can be temporarily modified with the chcon command.
164       If you want to permanently change the file context you need to use  the
165       semanage fcontext command.  This will modify the SELinux labeling data‐
166       base.  You will need to use restorecon to apply the labels.
167
168

COMMANDS

170       semanage fcontext can also be used to manipulate default  file  context
171       mappings.
172
173       semanage  permissive  can  also  be used to manipulate whether or not a
174       process type is permissive.
175
176       semanage module can also be used to enable/disable/install/remove  pol‐
177       icy modules.
178
179       semanage boolean can also be used to manipulate the booleans
180
181
182       system-config-selinux is a GUI tool available to customize SELinux pol‐
183       icy settings.
