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-updater,
31       /usr/bin/swift-object-expirer,          /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

PROCESS TYPES

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

BOOLEANS

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

MANAGED FILES

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

FILE CONTEXTS

254       SELinux requires files to have an extended attribute to define the file
255       type.
256
257       You can see the context of a file using the -Z option to ls
258
259       Policy governs the access  confined  processes  have  to  these  files.
260       SELinux  swift  policy  is  very flexible allowing users to setup their
261       swift processes in as secure a method as possible.
262
263       STANDARD FILE CONTEXT
264
265       SELinux defines the file context types for the swift, if you wanted  to
266       store  files  with  these types in a diffent paths, you need to execute
267       the semanage command  to  sepecify  alternate  labeling  and  then  use
268       restorecon to put the labels on disk.
269
270       semanage fcontext -a -t swift_var_run_t '/srv/myswift_content(/.*)?'
271       restorecon -R -v /srv/myswift_content
272
273       Note:  SELinux  often  uses  regular expressions to specify labels that
274       match multiple files.
275
276       The following file types are defined for swift:
277
278
279
280       swift_data_t
281
282       - Set files with the swift_data_t type, if you want to treat the  files
283       as swift content.
284
285
286       Paths:
287            /srv/node(/.*)?, /srv/loopback-device(/.*)?
288
289
290       swift_exec_t
291
292       -  Set  files  with the swift_exec_t type, if you want to transition an
293       executable to the swift_t domain.
294
295
296       Paths:
297            /usr/bin/swift-object-info,           /usr/bin/swift-proxy-server,
298            /usr/bin/swift-object-server,       /usr/bin/swift-account-reaper,
299            /usr/bin/swift-account-server,      /usr/bin/swift-container-sync,
300            /usr/bin/swift-object-auditor,      /usr/bin/swift-object-updater,
301            /usr/bin/swift-object-expirer,     /usr/bin/swift-account-auditor,
302            /usr/bin/swift-container-server, /usr/bin/swift-container-auditor,
303            /usr/bin/swift-container-updater,   /usr/bin/swift-object-replica‐
304            tor,  /usr/bin/swift-account-replicator, /usr/bin/swift-container-
305            replicator
306
307
308       swift_initrc_exec_t
309
310       - Set files with the swift_initrc_exec_t type, if you want  to  transi‐
311       tion an executable to the swift_initrc_t domain.
312
313
314       Paths:
315            /etc/rc.d/init.d/openstack-swift-proxy,     /etc/rc.d/init.d/open‐
316            stack-swift-object-expirer
317
318
319       swift_lock_t
320
321       - Set files with the swift_lock_t type, if you want to treat the  files
322       as swift lock data, stored under the /var/lock directory
323
324
325
326       swift_log_t
327
328       - Set files with the swift_log_t type, if you want to treat the data as
329       swift log data, usually stored under the /var/log directory.
330
331
332
333       swift_tmp_t
334
335       - Set files with the swift_tmp_t type, if you want to store swift  tem‐
336       porary files in the /tmp directories.
337
338
339
340       swift_tmpfs_t
341
342       -  Set  files  with  the swift_tmpfs_t type, if you want to store swift
343       files on a tmpfs file system.
344
345
346
347       swift_var_cache_t
348
349       - Set files with the swift_var_cache_t type, if you want to  store  the
350       files under the /var/cache directory.
351
352
353
354       swift_var_run_t
355
356       -  Set  files  with  the swift_var_run_t type, if you want to store the
357       swift files under the /run or /var/run directory.
358
359
360
361       Note: File context can be temporarily modified with the chcon  command.
362       If  you want to permanently change the file context you need to use the
363       semanage fcontext command.  This will modify the SELinux labeling data‐
364       base.  You will need to use restorecon to apply the labels.
365
366

COMMANDS

368       semanage  fcontext  can also be used to manipulate default file context
369       mappings.
370
371       semanage permissive can also be used to manipulate  whether  or  not  a
372       process type is permissive.
373
374       semanage  module can also be used to enable/disable/install/remove pol‐
375       icy modules.
376
377       semanage boolean can also be used to manipulate the booleans
378
379
380       system-config-selinux is a GUI tool available to customize SELinux pol‐
381       icy settings.
