NAME

6       cinder_backup_selinux  -  Security  Enhanced  Linux Policy for the cin‐
7       der_backup processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The   cinder_backup_t   SELinux  type  can  be  entered  via  the  cin‐
25       der_backup_exec_t file type.
26
27       The default entrypoint paths for the  cinder_backup_t  domain  are  the
28       following:
29
30       /usr/bin/cinder-backup
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_backup  policy  is  very  flexible allowing users to setup their
40       cinder_backup processes in as secure a method as possible.
41
42       The following process types are defined for cinder_backup:
43
44       cinder_backup_t
45
46       Note: semanage permissive -a cinder_backup_t can be used  to  make  the
47       process  type  cinder_backup_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.

51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  cin‐
54       der_backup policy is extremely flexible and has several  booleans  that
55       allow  you  to  manipulate  the  policy  and run cinder_backup with the
56       tightest 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  allow  system  to run with NIS, you must turn on the
86       nis_enabled boolean. Disabled by default.
87
88       setsebool -P nis_enabled 1
89
90
91
92       If you want to disable kernel module loading, you must turn on the  se‐
93       cure_mode_insmod boolean. Disabled by default.
94
95       setsebool -P secure_mode_insmod 1
96
97
98
99       If  you  want to allow unconfined executables to make their heap memory
100       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
101       badly  coded  executable, but could indicate an attack. This executable
102       should be reported in bugzilla, you must turn  on  the  selinuxuser_ex‐
103       echeap boolean. Disabled by default.
104
105       setsebool -P selinuxuser_execheap 1
106
107
108
109       If  you  want  to allow unconfined executables to make their stack exe‐
110       cutable.  This should never, ever be necessary.  Probably  indicates  a
111       badly  coded  executable, but could indicate an attack. This executable
112       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
113       stack boolean. Enabled by default.
114
115       setsebool -P selinuxuser_execstack 1

MANAGED FILES

120       The  SELinux process type cinder_backup_t can manage files labeled with
121       the following file types.  The paths listed are the default  paths  for
122       these  file  types.  Note the processes UID still need to have DAC per‐
123       missions.
124
125       file_type
126
127            all files on the system
128
129

FILE CONTEXTS

131       SELinux requires files to have an extended attribute to define the file
132       type.
133
134       You can see the context of a file using the -Z option to ls
135
136       Policy  governs  the  access  confined  processes  have to these files.
137       SELinux cinder_backup policy is very flexible allowing users  to  setup
138       their cinder_backup processes in as secure a method as possible.
139
140       STANDARD FILE CONTEXT
141
142       SELinux  defines  the  file context types for the cinder_backup, if you
143       wanted to store files with these types in a different paths,  you  need
144       to  execute the semanage command to specify alternate labeling and then
145       use restorecon to put the labels on disk.
146
147       semanage fcontext -a -t  cinder_backup_exec_t  '/srv/cinder_backup/con‐
148       tent(/.*)?'
149       restorecon -R -v /srv/mycinder_backup_content
150
151       Note:  SELinux  often  uses  regular expressions to specify labels that
152       match multiple files.
153
154       The following file types are defined for cinder_backup:
155
156
157
158       cinder_backup_exec_t
159
160       - Set files with the cinder_backup_exec_t type, if you want to  transi‐
161       tion an executable to the cinder_backup_t domain.
162
163
164
165       cinder_backup_tmp_t
166
167       -  Set  files  with  the cinder_backup_tmp_t type, if you want to store
168       cinder backup temporary files in the /tmp directories.
169
170
171
172       cinder_backup_unit_file_t
173
174       - Set files with the cinder_backup_unit_file_t type,  if  you  want  to
175       treat the files as cinder backup unit content.
176
177
178
179       Note:  File context can be temporarily modified with the chcon command.
180       If you want to permanently change the file context you need to use  the
181       semanage fcontext command.  This will modify the SELinux labeling data‐
182       base.  You will need to use restorecon to apply the labels.
183
184

COMMANDS

186       semanage fcontext can also be used to manipulate default  file  context
187       mappings.
188
189       semanage  permissive  can  also  be used to manipulate whether or not a
190       process type is permissive.
191
192       semanage module can also be used to enable/disable/install/remove  pol‐
193       icy modules.
194
195       semanage boolean can also be used to manipulate the booleans
196
197
198       system-config-selinux is a GUI tool available to customize SELinux pol‐
199       icy settings.
