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 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 For example:
18 ps -eZ | grep cinder_api_t
20
24 The cinder_api_t SELinux type can be entered via the cinder_api_exec_t
25 file type.
26 The default entrypoint paths for the cinder_api_t domain are the fol‐
28 lowing:
29 /usr/bin/cinder-api
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for cinder_api:
43 cinder_api_t
45 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
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 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 setsebool -P daemons_dontaudit_scheduling 1
65 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 setsebool -P deny_execmem 1
74 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 setsebool -P mmap_low_allowed 1
82 If you want to disable kernel module loading, you must turn on the se‐
86 cure_mode_insmod boolean. Disabled by default.
87 setsebool -P secure_mode_insmod 1
89 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 setsebool -P selinuxuser_execheap 1
99 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 setsebool -P selinuxuser_execstack 1
109
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 file_type
118 all files on the system
120
123 SELinux requires files to have an extended attribute to define the file
124 type.
125 You can see the context of a file using the -Z option to ls
127 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 STANDARD FILE CONTEXT
133 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 semanage fcontext -a -t cinder_api_exec_t '/srv/cinder_api/con‐
140 tent(/.*)?'
141 restorecon -R -v /srv/mycinder_api_content
142 Note: SELinux often uses regular expressions to specify labels that
144 match multiple files.
145 The following file types are defined for cinder_api:
147 cinder_api_exec_t
151 - Set files with the cinder_api_exec_t type, if you want to transition
153 an executable to the cinder_api_t domain.
154 cinder_api_tmp_t
158 - Set files with the cinder_api_tmp_t type, if you want to store cinder
160 api temporary files in the /tmp directories.
161 cinder_api_unit_file_t
165 - Set files with the cinder_api_unit_file_t type, if you want to treat
167 the files as cinder api unit content.
168 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
178 semanage fcontext can also be used to manipulate default file context
179 mappings.
180 semanage permissive can also be used to manipulate whether or not a
182 process type is permissive.
183 semanage module can also be used to enable/disable/install/remove pol‐
185 icy modules.
186 semanage boolean can also be used to manipulate the booleans
188 system-config-selinux is a GUI tool available to customize SELinux pol‐
191 icy settings.
