6 glusterd_selinux - Security Enhanced Linux Policy for the glusterd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the glusterd processes via flexible
11 mandatory access control.
12 The glusterd processes execute with the glusterd_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep glusterd_t
20
24 The glusterd_t SELinux type can be entered via the glusterd_exec_t file
25 type.
26 The default entrypoint paths for the glusterd_t domain are the follow‐
28 ing:
29 /opt/glusterfs/[^/]+/sbin/glusterfsd, /usr/libexec/glus‐
31 terfs/peer_eventsapi.py, /usr/libexec/glusterfs/events/glus‐
32 tereventsd.py, /usr/sbin/glusterfsd, /usr/sbin/glustereventsd,
33 /usr/sbin/gluster-eventsapi
34
36 SELinux defines process types (domains) for each process running on the
37 system
38 You can see the context of a process using the -Z option to ps
40 Policy governs the access confined processes have to files. SELinux
42 glusterd policy is very flexible allowing users to setup their glusterd
43 processes in as secure a method as possible.
44 The following process types are defined for glusterd:
46 glusterd_t
48 Note: semanage permissive -a glusterd_t can be used to make the process
50 type glusterd_t permissive. SELinux does not deny access to permissive
51 process types, but the AVC (SELinux denials) messages are still gener‐
52 ated.
53
56 SELinux policy is customizable based on least access required. glus‐
57 terd policy is extremely flexible and has several booleans that allow
58 you to manipulate the policy and run glusterd with the tightest access
59 possible.
60 If you want to allow glusterfsd to share any file/directory read only,
64 you must turn on the gluster_export_all_ro boolean. Disabled by de‐
65 fault.
66 setsebool -P gluster_export_all_ro 1
68 If you want to allow glusterfsd to share any file/directory read/write,
72 you must turn on the gluster_export_all_rw boolean. Enabled by default.
73 setsebool -P gluster_export_all_rw 1
75 If you want to allow glusterd_t domain to use executable memory, you
79 must turn on the gluster_use_execmem boolean. Disabled by default.
80 setsebool -P gluster_use_execmem 1
82 If you want to dontaudit all daemons scheduling requests (setsched,
86 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
87 Enabled by default.
88 setsebool -P daemons_dontaudit_scheduling 1
90 If you want to allow all domains to execute in fips_mode, you must turn
94 on the fips_mode boolean. Enabled by default.
95 setsebool -P fips_mode 1
97 If you want to allow system to run with NIS, you must turn on the
101 nis_enabled boolean. Disabled by default.
102 setsebool -P nis_enabled 1
104
108 SELinux defines port types to represent TCP and UDP ports.
109 You can see the types associated with a port by using the following
111 command:
112 semanage port -l
114 Policy governs the access confined processes have to these ports.
117 SELinux glusterd policy is very flexible allowing users to setup their
118 glusterd processes in as secure a method as possible.
119 The following port types are defined for glusterd:
121 gluster_port_t
124 Default Defined Ports:
128 tcp 38465-38469,24007-24027
129
131 The SELinux process type glusterd_t can manage files labeled with the
132 following file types. The paths listed are the default paths for these
133 file types. Note the processes UID still need to have DAC permissions.

235 SELinux requires files to have an extended attribute to define the file
236 type.
237 You can see the context of a file using the -Z option to ls
239 Policy governs the access confined processes have to these files.
241 SELinux glusterd policy is very flexible allowing users to setup their
242 glusterd processes in as secure a method as possible.
243 EQUIVALENCE DIRECTORIES
245 glusterd policy stores data with multiple different file context types
248 under the /var/run/gluster directory. If you would like to store the
249 data in a different directory you can use the semanage command to cre‐
250 ate an equivalence mapping. If you wanted to store this data under the
251 /srv directory you would execute the following command:
252 semanage fcontext -a -e /var/run/gluster /srv/gluster
254 restorecon -R -v /srv/gluster
255 STANDARD FILE CONTEXT
257 SELinux defines the file context types for the glusterd, if you wanted
259 to store files with these types in a different paths, you need to exe‐
260 cute the semanage command to specify alternate labeling and then use
261 restorecon to put the labels on disk.
262 semanage fcontext -a -t glusterd_exec_t '/srv/glusterd/content(/.*)?'
264 restorecon -R -v /srv/myglusterd_content
265 Note: SELinux often uses regular expressions to specify labels that
267 match multiple files.
268 The following file types are defined for glusterd:
270 glusterd_brick_t
274 - Set files with the glusterd_brick_t type, if you want to treat the
276 files as glusterd brick data.
277 glusterd_conf_t
281 - Set files with the glusterd_conf_t type, if you want to treat the
283 files as glusterd configuration data, usually stored under the /etc di‐
284 rectory.
285 Paths:
288 /etc/glusterd(/.*)?, /etc/glusterfs(/.*)?
289 glusterd_exec_t
292 - Set files with the glusterd_exec_t type, if you want to transition an
294 executable to the glusterd_t domain.
295 Paths:
298 /opt/glusterfs/[^/]+/sbin/glusterfsd, /usr/libexec/glus‐
299 terfs/peer_eventsapi.py, /usr/libexec/glusterfs/events/glus‐
300 tereventsd.py, /usr/sbin/glusterfsd, /usr/sbin/glustereventsd,
301 /usr/sbin/gluster-eventsapi
302 glusterd_initrc_exec_t
305 - Set files with the glusterd_initrc_exec_t type, if you want to tran‐
307 sition an executable to the glusterd_initrc_t domain.
308 Paths:
311 /etc/rc.d/init.d/gluster.*, /usr/sbin/glusterd
312 glusterd_log_t
315 - Set files with the glusterd_log_t type, if you want to treat the data
317 as glusterd log data, usually stored under the /var/log directory.
318 glusterd_tmp_t
322 - Set files with the glusterd_tmp_t type, if you want to store glusterd
324 temporary files in the /tmp directories.
325 glusterd_tmpfs_t
329 - Set files with the glusterd_tmpfs_t type, if you want to store glus‐
331 terd files on a tmpfs file system.
332 glusterd_var_lib_t
336 - Set files with the glusterd_var_lib_t type, if you want to store the
338 glusterd files under the /var/lib directory.
339 glusterd_var_run_t
343 - Set files with the glusterd_var_run_t type, if you want to store the
345 glusterd files under the /run or /var/run directory.
346 Paths:
349 /var/run/gluster(/.*)?, /var/run/glusterd.*, /var/run/glusterd.*,
350 /var/run/glusterd(/.*)?
351 Note: File context can be temporarily modified with the chcon command.
354 If you want to permanently change the file context you need to use the
355 semanage fcontext command. This will modify the SELinux labeling data‐
356 base. You will need to use restorecon to apply the labels.
357
360 If you want to share files with multiple domains (Apache, FTP, rsync,
361 Samba), you can set a file context of public_content_t and public_con‐
362 tent_rw_t. These context allow any of the above domains to read the
363 content. If you want a particular domain to write to the public_con‐
364 tent_rw_t domain, you must set the appropriate boolean.
365 Allow glusterd servers to read the /var/glusterd directory by adding
367 the public_content_t file type to the directory and by restoring the
368 file type.
369 semanage fcontext -a -t public_content_t "/var/glusterd(/.*)?"
371 restorecon -F -R -v /var/glusterd
372 Allow glusterd servers to read and write /var/glusterd/incoming by
374 adding the public_content_rw_t type to the directory and by restoring
375 the file type. You also need to turn on the glusterd_anon_write bool‐
376 ean.
377 semanage fcontext -a -t public_content_rw_t "/var/glusterd/incom‐
379 ing(/.*)?"
380 restorecon -F -R -v /var/glusterd/incoming
381 setsebool -P glusterd_anon_write 1
382 If you want to allow glusterfsd to modify public files used for public
385 file transfer services. Files/Directories must be labeled public_con‐
386 tent_rw_t., you must turn on the gluster_anon_write boolean.
387 setsebool -P gluster_anon_write 1
389
392 semanage fcontext can also be used to manipulate default file context
393 mappings.
394 semanage permissive can also be used to manipulate whether or not a
396 process type is permissive.
397 semanage module can also be used to enable/disable/install/remove pol‐
399 icy modules.
400 semanage port can also be used to manipulate the port definitions
402 semanage boolean can also be used to manipulate the booleans
404 system-config-selinux is a GUI tool available to customize SELinux pol‐
407 icy settings.
