6 cinder_api_selinux - Security Enhanced Linux Policy for the cinder_api
7 processes
8
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
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
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
53 SELinux policy is customizable based on least access required. cin‐
54 der_api policy is extremely flexible and has several booleans that
55 allow 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
78 secure_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 selin‐
88 uxuser_execheap 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. Disabled by default.
99
100 setsebool -P selinuxuser_execstack 1
101
102
103
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
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
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.
