6 cinder_volume_selinux - Security Enhanced Linux Policy for the cin‐
7 der_volume processes
8
10 Security-Enhanced Linux secures the cinder_volume processes via flexi‐
11 ble mandatory access control.
12 The cinder_volume processes execute with the cinder_volume_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep cinder_volume_t
20
24 The cinder_volume_t SELinux type can be entered via the cinder_vol‐
25 ume_exec_t file type.
26 The default entrypoint paths for the cinder_volume_t domain are the
28 following:
29 /usr/bin/cinder-volume
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_volume policy is very flexible allowing users to setup their
40 cinder_volume processes in as secure a method as possible.
41 The following process types are defined for cinder_volume:
43 cinder_volume_t
45 Note: semanage permissive -a cinder_volume_t can be used to make the
47 process type cinder_volume_t permissive. SELinux does not deny access
48 to 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_volume policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run cinder_volume with the
56 tightest 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_volume_t can manage files labeled with
114 the following file types. The paths listed are the default paths for
115 these file types. Note the processes UID still need to have DAC per‐
116 missions.
117 file_type
119 all files on the system
121
124 SELinux requires files to have an extended attribute to define the file
125 type.
126 You can see the context of a file using the -Z option to ls
128 Policy governs the access confined processes have to these files.
130 SELinux cinder_volume policy is very flexible allowing users to setup
131 their cinder_volume processes in as secure a method as possible.
132 STANDARD FILE CONTEXT
134 SELinux defines the file context types for the cinder_volume, if you
136 wanted to store files with these types in a different paths, you need
137 to execute the semanage command to specify alternate labeling and then
138 use restorecon to put the labels on disk.
139 semanage fcontext -a -t cinder_volume_exec_t '/srv/cinder_volume/con‐
141 tent(/.*)?'
142 restorecon -R -v /srv/mycinder_volume_content
143 Note: SELinux often uses regular expressions to specify labels that
145 match multiple files.
146 The following file types are defined for cinder_volume:
148 cinder_volume_exec_t
152 - Set files with the cinder_volume_exec_t type, if you want to transi‐
154 tion an executable to the cinder_volume_t domain.
155 cinder_volume_tmp_t
159 - Set files with the cinder_volume_tmp_t type, if you want to store
161 cinder volume temporary files in the /tmp directories.
162 cinder_volume_unit_file_t
166 - Set files with the cinder_volume_unit_file_t type, if you want to
168 treat the files as cinder volume unit content.
169 Note: File context can be temporarily modified with the chcon command.
173 If you want to permanently change the file context you need to use the
174 semanage fcontext command. This will modify the SELinux labeling data‐
175 base. You will need to use restorecon to apply the labels.
176
179 semanage fcontext can also be used to manipulate default file context
180 mappings.
181 semanage permissive can also be used to manipulate whether or not a
183 process type is permissive.
184 semanage module can also be used to enable/disable/install/remove pol‐
186 icy modules.
187 semanage boolean can also be used to manipulate the booleans
189 system-config-selinux is a GUI tool available to customize SELinux pol‐
192 icy settings.
