NAME

6       zebra_selinux - Security Enhanced Linux Policy for the zebra processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the zebra processes via flexible manda‐
10       tory access control.
11
12       The zebra processes execute with the  zebra_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 zebra_t
19
20
21

ENTRYPOINTS

23       The zebra_t SELinux type can be entered via the zebra_exec_t file type.
24
25       The default entrypoint paths for the zebra_t domain are the following:
26
27       /usr/sbin/rip.*,  /usr/sbin/ospf.*,  /usr/sbin/bgpd,   /usr/sbin/isisd,
28       /usr/sbin/zebra, /usr/sbin/babeld
29

PROCESS TYPES

31       SELinux defines process types (domains) for each process running on the
32       system
33
34       You can see the context of a process using the -Z option to ps
35
36       Policy governs the access confined processes have  to  files.   SELinux
37       zebra  policy is very flexible allowing users to setup their zebra pro‐
38       cesses in as secure a method as possible.
39
40       The following process types are defined for zebra:
41
42       zebra_t
43
44       Note: semanage permissive -a zebra_t can be used to  make  the  process
45       type  zebra_t  permissive.  SELinux  does not deny access to permissive
46       process types, but the AVC (SELinux denials) messages are still  gener‐
47       ated.
48
49

BOOLEANS

51       SELinux  policy  is customizable based on least access required.  zebra
52       policy is extremely flexible and has several booleans that allow you to
53       manipulate the policy and run zebra with the tightest access possible.
54

PORT TYPES

175       SELinux defines port types to represent TCP and UDP ports.
176
177       You can see the types associated with a port  by  using  the  following
178       command:
179
180       semanage port -l
181
182
183       Policy  governs  the  access  confined  processes  have to these ports.
184       SELinux zebra policy is very flexible allowing  users  to  setup  their
185       zebra processes in as secure a method as possible.
186
187       The following port types are defined for zebra:
188
189
190       zebra_port_t
191
192
193
194       Default Defined Ports:
195                 tcp 2606,2608-2609,2600-2604
196                 udp 2606,2608-2609,2600-2604
197

MANAGED FILES

199       The SELinux process type zebra_t can manage files labeled with the fol‐
200       lowing file types.  The paths listed are the default  paths  for  these
201       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

259       SELinux requires files to have an extended attribute to define the file
260       type.
261
262       You can see the context of a file using the -Z option to ls
263
264       Policy governs the access  confined  processes  have  to  these  files.
265       SELinux  zebra  policy  is  very flexible allowing users to setup their
266       zebra processes in as secure a method as possible.
267
268       STANDARD FILE CONTEXT
269
270       SELinux defines the file context types for the zebra, if you wanted  to
271       store  files  with  these types in a diffent paths, you need to execute
272       the semanage command  to  sepecify  alternate  labeling  and  then  use
273       restorecon to put the labels on disk.
274
275       semanage fcontext -a -t zebra_var_run_t '/srv/myzebra_content(/.*)?'
276       restorecon -R -v /srv/myzebra_content
277
278       Note:  SELinux  often  uses  regular expressions to specify labels that
279       match multiple files.
280
281       The following file types are defined for zebra:
282
283
284
285       zebra_conf_t
286
287       - Set files with the zebra_conf_t type, if you want to treat the  files
288       as zebra configuration data, usually stored under the /etc directory.
289
290
291       Paths:
292            /etc/zebra(/.*)?, /etc/quagga(/.*)?
293
294
295       zebra_exec_t
296
297       -  Set  files  with the zebra_exec_t type, if you want to transition an
298       executable to the zebra_t domain.
299
300
301       Paths:
302            /usr/sbin/rip.*,         /usr/sbin/ospf.*,         /usr/sbin/bgpd,
303            /usr/sbin/isisd, /usr/sbin/zebra, /usr/sbin/babeld
304
305
306       zebra_initrc_exec_t
307
308       -  Set  files with the zebra_initrc_exec_t type, if you want to transi‐
309       tion an executable to the zebra_initrc_t domain.
310
311
312       Paths:
313            /etc/rc.d/init.d/bgpd,                      /etc/rc.d/init.d/ripd,
314            /etc/rc.d/init.d/ospfd,                    /etc/rc.d/init.d/zebra,
315            /etc/rc.d/init.d/isisd,                   /etc/rc.d/init.d/ospf6d,
316            /etc/rc.d/init.d/ripngd, /etc/rc.d/init.d/babeld
317
318
319       zebra_log_t
320
321       - Set files with the zebra_log_t type, if you want to treat the data as
322       zebra log data, usually stored under the /var/log directory.
323
324
325       Paths:
326            /var/log/zebra(/.*)?, /var/log/quagga(/.*)?
327
328
329       zebra_tmp_t
330
331       - Set files with the zebra_tmp_t type, if you want to store zebra  tem‐
332       porary files in the /tmp directories.
333
334
335
336       zebra_unit_file_t
337
338       -  Set  files with the zebra_unit_file_t type, if you want to treat the
339       files as zebra unit content.
340
341
342       Paths:
343            /usr/lib/systemd/system/bgpd.*,    /usr/lib/systemd/system/ripd.*,
344            /usr/lib/systemd/system/isisd.*,  /usr/lib/systemd/system/ospfd.*,
345            /usr/lib/systemd/system/zebra.*, /usr/lib/systemd/system/babeld.*,
346            /usr/lib/systemd/system/ospf6d.*, /usr/lib/systemd/system/ripngd.*
347
348
349       zebra_var_run_t
350
351       -  Set  files  with  the zebra_var_run_t type, if you want to store the
352       zebra files under the /run or /var/run directory.
353
354
355       Paths:
356            /var/run/quagga(/.*)?, /var/run/.zebra, /var/run/.zserv
357
358
359       Note: File context can be temporarily modified with the chcon  command.
360       If  you want to permanently change the file context you need to use the
361       semanage fcontext command.  This will modify the SELinux labeling data‐
362       base.  You will need to use restorecon to apply the labels.
363
364

COMMANDS

366       semanage  fcontext  can also be used to manipulate default file context
367       mappings.
368
369       semanage permissive can also be used to manipulate  whether  or  not  a
370       process type is permissive.
371
372       semanage  module can also be used to enable/disable/install/remove pol‐
373       icy modules.
374
375       semanage port can also be used to manipulate the port definitions
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.
