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
20

22

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 allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 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. Enabled by default.
72
73       setsebool -P deny_execmem 1
74
75
76
77       If you want to allow all domains to execute in fips_mode, you must turn
78       on the fips_mode boolean. Enabled by default.
79
80       setsebool -P fips_mode 1
81
82
83
84       If you want to allow confined applications to run  with  kerberos,  you
85       must turn on the kerberos_enabled boolean. Enabled by default.
86
87       setsebool -P kerberos_enabled 1
88
89
90
91       If  you  want  to control the ability to mmap a low area of the address
92       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
93       the mmap_low_allowed boolean. Disabled by default.
94
95       setsebool -P mmap_low_allowed 1
96
97
98
99       If  you  want  to  allow  system  to run with NIS, you must turn on the
100       nis_enabled boolean. Disabled by default.
101
102       setsebool -P nis_enabled 1
103
104
105
106       If you want to allow confined applications to use nscd  shared  memory,
107       you must turn on the nscd_use_shm boolean. Disabled by default.
108
109       setsebool -P nscd_use_shm 1
110
111
112
113       If  you  want  to  disable  kernel module loading, you must turn on the
114       secure_mode_insmod boolean. Enabled by default.
115
116       setsebool -P secure_mode_insmod 1
117
118
119
120       If you want to allow unconfined executables to make their  heap  memory
121       executable.   Doing  this  is  a  really bad idea. Probably indicates a
122       badly coded executable, but could indicate an attack.  This  executable
123       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
124       uxuser_execheap boolean. Disabled by default.
125
126       setsebool -P selinuxuser_execheap 1
127
128
129
130       If you want to allow unconfined executables to make  their  stack  exe‐
131       cutable.   This  should  never, ever be necessary. Probably indicates a
132       badly coded executable, but could indicate an attack.  This  executable
133       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
134       stack boolean. Enabled by default.
135
136       setsebool -P selinuxuser_execstack 1

MANAGED FILES

141       The SELinux process type cinder_backup_t can manage files labeled  with
142       the  following  file types.  The paths listed are the default paths for
143       these file types.  Note the processes UID still need to have  DAC  per‐
144       missions.
145
146       file_type
147
148            all files on the system
149
150

FILE CONTEXTS

152       SELinux requires files to have an extended attribute to define the file
153       type.
154
155       You can see the context of a file using the -Z option to ls
156
157       Policy governs the access  confined  processes  have  to  these  files.
158       SELinux  cinder_backup  policy is very flexible allowing users to setup
159       their cinder_backup processes in as secure a method as possible.
160
161       STANDARD FILE CONTEXT
162
163       SELinux defines the file context types for the  cinder_backup,  if  you
164       wanted  to store files with these types in a diffent paths, you need to
165       execute the semanage command to sepecify alternate  labeling  and  then
166       use restorecon to put the labels on disk.
167
168       semanage  fcontext -a -t cinder_backup_tmp_t '/srv/mycinder_backup_con‐
169       tent(/.*)?'
170       restorecon -R -v /srv/mycinder_backup_content
171
172       Note: SELinux often uses regular expressions  to  specify  labels  that
173       match multiple files.
174
175       The following file types are defined for cinder_backup:
176
177
178
179       cinder_backup_exec_t
180
181       -  Set files with the cinder_backup_exec_t type, if you want to transi‐
182       tion an executable to the cinder_backup_t domain.
183
184
185
186       cinder_backup_tmp_t
187
188       - Set files with the cinder_backup_tmp_t type, if  you  want  to  store
189       cinder backup temporary files in the /tmp directories.
190
191
192
193       cinder_backup_unit_file_t
194
195       -  Set  files  with  the cinder_backup_unit_file_t type, if you want to
196       treat the files as cinder backup unit content.
197
198
199
200       Note: File context can be temporarily modified with the chcon  command.
201       If  you want to permanently change the file context you need to use the
202       semanage fcontext command.  This will modify the SELinux labeling data‐
203       base.  You will need to use restorecon to apply the labels.
204
205

COMMANDS

207       semanage  fcontext  can also be used to manipulate default file context
208       mappings.
209
210       semanage permissive can also be used to manipulate  whether  or  not  a
211       process type is permissive.
212
213       semanage  module can also be used to enable/disable/install/remove pol‐
214       icy modules.
215
216       semanage boolean can also be used to manipulate the booleans
217
218
219       system-config-selinux is a GUI tool available to customize SELinux pol‐
220       icy settings.
