NAME

6       haproxy_selinux  -  Security Enhanced Linux Policy for the haproxy pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The  haproxy_t  SELinux type can be entered via the haproxy_exec_t file
25       type.
26
27       The default entrypoint paths for the haproxy_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/haproxy, /usr/sbin/haproxy-systemd-wrapper
31

PROCESS TYPES

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

BOOLEANS

53       SELinux policy is customizable based on least access required.  haproxy
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run haproxy with the tightest access possi‐
56       ble.

187       following file types.  The paths listed are the default paths for these
188       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

243       SELinux requires files to have an extended attribute to define the file
244       type.
245
246       You can see the context of a file using the -Z option to ls
247
248       Policy governs the access  confined  processes  have  to  these  files.
249       SELinux  haproxy  policy is very flexible allowing users to setup their
250       haproxy processes in as secure a method as possible.
251
252       STANDARD FILE CONTEXT
253
254       SELinux defines the file context types for the haproxy, if  you  wanted
255       to store files with these types in a diffent paths, you need to execute
256       the semanage command  to  sepecify  alternate  labeling  and  then  use
257       restorecon to put the labels on disk.
258
259       semanage   fcontext   -a   -t   haproxy_var_run_t  '/srv/myhaproxy_con‐
260       tent(/.*)?'
261       restorecon -R -v /srv/myhaproxy_content
262
263       Note: SELinux often uses regular expressions  to  specify  labels  that
264       match multiple files.
265
266       The following file types are defined for haproxy:
267
268
269
270       haproxy_exec_t
271
272       -  Set files with the haproxy_exec_t type, if you want to transition an
273       executable to the haproxy_t domain.
274
275
276       Paths:
277            /usr/sbin/haproxy, /usr/sbin/haproxy-systemd-wrapper
278
279
280       haproxy_tmpfs_t
281
282       - Set files with the haproxy_tmpfs_t type, if you want to store haproxy
283       files on a tmpfs file system.
284
285
286
287       haproxy_unit_file_t
288
289       - Set files with the haproxy_unit_file_t type, if you want to treat the
290       files as haproxy unit content.
291
292
293
294       haproxy_var_lib_t
295
296       - Set files with the haproxy_var_lib_t type, if you want to  store  the
297       haproxy files under the /var/lib directory.
298
299
300
301       haproxy_var_log_t
302
303       -  Set  files with the haproxy_var_log_t type, if you want to treat the
304       data as haproxy var log data, usually stored under the /var/log  direc‐
305       tory.
306
307
308
309       haproxy_var_run_t
310
311       -  Set  files with the haproxy_var_run_t type, if you want to store the
312       haproxy files under the /run or /var/run directory.
313
314
315       Paths:
316            /var/run/haproxy.stat.*,                  /var/run/haproxy.sock.*,
317            /var/run/haproxy.pid
318
319
320       Note:  File context can be temporarily modified with the chcon command.
321       If you want to permanently change the file context you need to use  the
322       semanage fcontext command.  This will modify the SELinux labeling data‐
323       base.  You will need to use restorecon to apply the labels.
324
325

COMMANDS

327       semanage fcontext can also be used to manipulate default  file  context
328       mappings.
329
330       semanage  permissive  can  also  be used to manipulate whether or not a
331       process type is permissive.
332
333       semanage module can also be used to enable/disable/install/remove  pol‐
334       icy modules.
335
336       semanage boolean can also be used to manipulate the booleans
337
338
339       system-config-selinux is a GUI tool available to customize SELinux pol‐
340       icy settings.
