NAME

6       nova_objectstore_selinux  -  Security  Enhanced  Linux  Policy  for the
7       nova_objectstore processes
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  nova_objectstore  processes  via
11       flexible mandatory access control.
12
13       The  nova_objectstore  processes  execute  with  the nova_objectstore_t
14       SELinux type. You can check if you have these processes running by exe‐
15       cuting the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep nova_objectstore_t
20
21
22

ENTRYPOINTS

24       The  nova_objectstore_t  SELinux type can be entered via the file_type,
25       unlabeled_t, proc_type,  filesystem_type,  mtrr_device_t,  sysctl_type,
26       nova_objectstore_exec_t file types.
27
28       The  default entrypoint paths for the nova_objectstore_t domain are the
29       following:
30
31       all files on the system, /dev/cpu/mtrr, /usr/bin/nova-objectstore
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       nova_objectstore policy is very flexible allowing users to setup  their
41       nova_objectstore processes in as secure a method as possible.
42
43       The following process types are defined for nova_objectstore:
44
45       nova_objectstore_t
46
47       Note: semanage permissive -a nova_objectstore_t can be used to make the
48       process type  nova_objectstore_t  permissive.  SELinux  does  not  deny
49       access  to permissive process types, but the AVC (SELinux denials) mes‐
50       sages are still generated.
51
52

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       nova_objectstore  policy is extremely flexible and has several booleans
56       that allow you to manipulate the policy and run  nova_objectstore  with
57       the tightest access possible.

60
61       If you want to allow all daemons to write corefiles to /, you must turn
62       on the allow_daemons_dump_core boolean. Disabled by default.

64       setsebool -P allow_daemons_dump_core 1
65
66
67
68       If you want to allow all daemons to use tcp wrappers, you must turn  on
69       the allow_daemons_use_tcp_wrapper boolean. Disabled by default.

87
88
89
90       If you want to allow unconfined executables to make their  heap  memory
91       executable.   Doing  this  is  a  really bad idea. Probably indicates a
92       badly coded executable, but could indicate an attack.  This  executable
93       should  be  reported  in  bugzilla, you must turn on the allow_execheap
94       boolean. Disabled by default.
95
96       setsebool -P allow_execheap 1
97
98
99
100       If you want to allow unconfined executables to map a memory  region  as
101       both  executable  and  writable,  this  is dangerous and the executable
102       should be reported in bugzilla), you must  turn  on  the  allow_execmem
103       boolean. Enabled by default.

110       requiring text relocation that are not  labeled  textrel_shlib_t),  you
111       must turn on the allow_execmod boolean. Enabled by default.
112
113       setsebool -P allow_execmod 1
114
115
116
117       If  you  want  to allow unconfined executables to make their stack exe‐
118       cutable.  This should never, ever be necessary.  Probably  indicates  a
119       badly  coded  executable, but could indicate an attack. This executable
120       should be reported in bugzilla), you must turn on  the  allow_execstack
121       boolean. Enabled by default.
122
123       setsebool -P allow_execstack 1
124
125

142       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
143       default.
144
145       setsebool -P domain_kernel_load_modules 1
146
147
148
149       If you want to allow all domains to execute in fips_mode, you must turn
150       on the fips_mode boolean. Enabled by default.
151
152       setsebool -P fips_mode 1
153
154

178       policy, setting enforcing mode, and changing boolean values.  Set  this
179       to  true  and  you  have to reboot to set it back, you must turn on the
180       secure_mode_policyload boolean. Disabled by default.
181
182       setsebool -P secure_mode_policyload 1

MANAGED FILES

194       The  SELinux  process  type nova_objectstore_t can manage files labeled
195       with the following file types.  The paths listed are the default  paths
196       for  these  file  types.  Note the processes UID still need to have DAC
197       permissions.
198
199       file_type
200
201            all files on the system
202
203

FILE CONTEXTS

205       SELinux requires files to have an extended attribute to define the file
206       type.
207
208       You can see the context of a file using the -Z option to ls
209
210       Policy  governs  the  access  confined  processes  have to these files.
211       SELinux nova_objectstore policy is very flexible allowing users to set‐
212       up their nova_objectstore processes in as secure a method as possible.
213
214       STANDARD FILE CONTEXT
215
216       SELinux defines the file context types for the nova_objectstore, if you
217       wanted to store files with these types in a diffent paths, you need  to
218       execute  the  semanage  command to sepecify alternate labeling and then
219       use restorecon to put the labels on disk.
220
221       semanage fcontext  -a  -t  nova_objectstore_tmp_t  '/srv/mynova_object‐
222       store_content(/.*)?'
223       restorecon -R -v /srv/mynova_objectstore_content
224
225       Note:  SELinux  often  uses  regular expressions to specify labels that
226       match multiple files.
227
228       The following file types are defined for nova_objectstore:
229
230
231
232       nova_objectstore_exec_t
233
234       - Set files with the nova_objectstore_exec_t type, if you want to tran‐
235       sition an executable to the nova_objectstore_t domain.
236
237
238
239       nova_objectstore_initrc_exec_t
240
241       -  Set  files with the nova_objectstore_initrc_exec_t type, if you want
242       to transition an executable to the nova_objectstore_initrc_t domain.
243
244
245
246       nova_objectstore_tmp_t
247
248       - Set files with the nova_objectstore_tmp_t type, if you want to  store
249       nova objectstore temporary files in the /tmp directories.
250
251
252
253       Note:  File context can be temporarily modified with the chcon command.
254       If you want to permanently change the file context you need to use  the
255       semanage fcontext command.  This will modify the SELinux labeling data‐
256       base.  You will need to use restorecon to apply the labels.
257
258

COMMANDS

260       semanage fcontext can also be used to manipulate default  file  context
261       mappings.
262
263       semanage  permissive  can  also  be used to manipulate whether or not a
264       process type is permissive.
265
266       semanage module can also be used to enable/disable/install/remove  pol‐
267       icy modules.
268
269       semanage boolean can also be used to manipulate the booleans
270
271
272       system-config-selinux is a GUI tool available to customize SELinux pol‐
273       icy settings.
