NAME

6       swift_selinux - Security Enhanced Linux Policy for the swift processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The swift_t SELinux type can be entered via the swift_exec_t file type.
24
25       The default entrypoint paths for the swift_t domain are the following:
26
27       /usr/bin/swift-object-info,                /usr/bin/swift-proxy-server,
28       /usr/bin/swift-object-server,            /usr/bin/swift-account-reaper,
29       /usr/bin/swift-account-server,           /usr/bin/swift-container-sync,
30       /usr/bin/swift-object-auditor,           /usr/bin/swift-object-expirer,
31       /usr/bin/swift-object-updater,          /usr/bin/swift-account-auditor,
32       /usr/bin/swift-container-server,      /usr/bin/swift-container-auditor,
33       /usr/bin/swift-container-updater,     /usr/bin/swift-object-replicator,
34       /usr/bin/swift-account-replicator, /usr/bin/swift-container-replicator,
35       /usr/bin/swift-container-reconciler
36

PROCESS TYPES

38       SELinux defines process types (domains) for each process running on the
39       system
40
41       You can see the context of a process using the -Z option to ps
42
43       Policy  governs  the  access confined processes have to files.  SELinux
44       swift policy is very flexible allowing users to setup their swift  pro‐
45       cesses in as secure a method as possible.
46
47       The following process types are defined for swift:
48
49       swift_t
50
51       Note:  semanage  permissive  -a swift_t can be used to make the process
52       type swift_t permissive. SELinux does not  deny  access  to  permissive
53       process  types, but the AVC (SELinux denials) messages are still gener‐
54       ated.
55
56

BOOLEANS

58       SELinux policy is customizable based on least access  required.   swift
59       policy is extremely flexible and has several booleans that allow you to
60       manipulate the policy and run swift with the tightest access possible.
61
62

PORT TYPES

182       SELinux defines port types to represent TCP and UDP ports.
183
184       You  can  see  the  types associated with a port by using the following
185       command:
186
187       semanage port -l
188
189
190       Policy governs the access  confined  processes  have  to  these  ports.
191       SELinux  swift  policy  is  very flexible allowing users to setup their
192       swift processes in as secure a method as possible.
193
194       The following port types are defined for swift:
195
196
197       swift_port_t
198
199
200
201       Default Defined Ports:
202                 tcp 6200-6203
203

MANAGED FILES

205       The SELinux process type swift_t can manage files labeled with the fol‐
206       lowing  file  types.   The paths listed are the default paths for these
207       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

270       SELinux requires files to have an extended attribute to define the file
271       type.
272
273       You can see the context of a file using the -Z option to ls
274
275       Policy  governs  the  access  confined  processes  have to these files.
276       SELinux swift policy is very flexible allowing  users  to  setup  their
277       swift processes in as secure a method as possible.
278
279       STANDARD FILE CONTEXT
280
281       SELinux  defines the file context types for the swift, if you wanted to
282       store files with these types in a diffent paths, you  need  to  execute
283       the  semanage  command  to  sepecify  alternate  labeling  and then use
284       restorecon to put the labels on disk.
285
286       semanage fcontext -a -t swift_var_run_t '/srv/myswift_content(/.*)?'
287       restorecon -R -v /srv/myswift_content
288
289       Note: SELinux often uses regular expressions  to  specify  labels  that
290       match multiple files.
291
292       The following file types are defined for swift:
293
294
295
296       swift_data_t
297
298       -  Set files with the swift_data_t type, if you want to treat the files
299       as swift content.
300
301
302       Paths:
303            /srv/node(/.*)?, /var/lib/swift(/.*)?, /srv/loopback-device(/.*)?
304
305
306       swift_exec_t
307
308       - Set files with the swift_exec_t type, if you want  to  transition  an
309       executable to the swift_t domain.
310
311
312       Paths:
313            /usr/bin/swift-object-info,           /usr/bin/swift-proxy-server,
314            /usr/bin/swift-object-server,       /usr/bin/swift-account-reaper,
315            /usr/bin/swift-account-server,      /usr/bin/swift-container-sync,
316            /usr/bin/swift-object-auditor,      /usr/bin/swift-object-expirer,
317            /usr/bin/swift-object-updater,     /usr/bin/swift-account-auditor,
318            /usr/bin/swift-container-server, /usr/bin/swift-container-auditor,
319            /usr/bin/swift-container-updater,   /usr/bin/swift-object-replica‐
320            tor, /usr/bin/swift-account-replicator,  /usr/bin/swift-container-
321            replicator, /usr/bin/swift-container-reconciler
322
323
324       swift_lock_t
325
326       -  Set files with the swift_lock_t type, if you want to treat the files
327       as swift lock data, stored under the /var/lock directory
328
329
330
331       swift_tmp_t
332
333       - Set files with the swift_tmp_t type, if you want to store swift  tem‐
334       porary files in the /tmp directories.
335
336
337
338       swift_tmpfs_t
339
340       -  Set  files  with  the swift_tmpfs_t type, if you want to store swift
341       files on a tmpfs file system.
342
343
344
345       swift_unit_file_t
346
347       - Set files with the swift_unit_file_t type, if you want to  treat  the
348       files as swift unit content.
349
350
351
352       swift_var_cache_t
353
354       -  Set  files with the swift_var_cache_t type, if you want to store the
355       files under the /var/cache directory.
356
357
358
359       swift_var_run_t
360
361       - Set files with the swift_var_run_t type, if you  want  to  store  the
362       swift files under the /run or /var/run directory.
363
364
365
366       Note:  File context can be temporarily modified with the chcon command.
367       If you want to permanently change the file context you need to use  the
368       semanage fcontext command.  This will modify the SELinux labeling data‐
369       base.  You will need to use restorecon to apply the labels.
370
371

COMMANDS

373       semanage fcontext can also be used to manipulate default  file  context
374       mappings.
375
376       semanage  permissive  can  also  be used to manipulate whether or not a
377       process type is permissive.
378
379       semanage module can also be used to enable/disable/install/remove  pol‐
380       icy modules.
381
382       semanage port can also be used to manipulate the port definitions
383
384       semanage boolean can also be used to manipulate the booleans
385
386
387       system-config-selinux is a GUI tool available to customize SELinux pol‐
388       icy settings.
