NAME

6       varnishlog_selinux  - Security Enhanced Linux Policy for the varnishlog
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  varnishlog_t SELinux type can be entered via the varnishlog_exec_t
25       file type.
26
27       The default entrypoint paths for the varnishlog_t domain are  the  fol‐
28       lowing:
29
30       /usr/bin/varnishlog, /usr/bin/varnisncsa
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       varnishlog  policy  is very flexible allowing users to setup their var‐
40       nishlog processes in as secure a method as possible.
41
42       The following process types are defined for varnishlog:
43
44       varnishlog_t
45
46       Note: semanage permissive -a varnishlog_t  can  be  used  to  make  the
47       process  type  varnishlog_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  var‐
54       nishlog policy is extremely flexible  and  has  several  booleans  that
55       allow you to manipulate the policy and run varnishlog with the tightest
56       access possible.
57
58
59
60       If you want to allow all daemons to write corefiles to /, you must turn
61       on the daemons_dump_core boolean. Disabled by default.

71
72
73
74       If you want to allow all daemons to use tcp wrappers, you must turn  on

78
79
80
81       If  you  want to allow all daemons the ability to read/write terminals,

85
86
87
88       If you want to deny any process from ptracing or  debugging  any  other
89       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
90       default.
91
92       setsebool -P deny_ptrace 1
93
94
95
96       If you want to allow any process  to  mmap  any  file  on  system  with
97       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
98       ean. Enabled by default.

101
102
103
104       If you want to allow all domains write to kmsg_device, while kernel  is
105       executed  with  systemd.log_target=kmsg parameter, you must turn on the
106       domain_can_write_kmsg boolean. Disabled by default.

118
119       If  you  want to allow all domains to have the kernel load modules, you
120       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
121       default.
122
123       setsebool -P domain_kernel_load_modules 1

MANAGED FILES

142       The SELinux process type varnishlog_t can manage files labeled with the
143       following file types.  The paths listed are the default paths for these
144       file types.  Note the processes UID still need to have DAC permissions.
145
146       cluster_conf_t
147
148            /etc/cluster(/.*)?

FILE CONTEXTS

188       SELinux requires files to have an extended attribute to define the file
189       type.
190
191       You can see the context of a file using the -Z option to ls
192
193       Policy governs the access  confined  processes  have  to  these  files.
194       SELinux  varnishlog  policy  is  very  flexible allowing users to setup
195       their varnishlog processes in as secure a method as possible.
196
197       STANDARD FILE CONTEXT
198
199       SELinux defines the file context  types  for  the  varnishlog,  if  you
200       wanted  to store files with these types in a diffent paths, you need to
201       execute the semanage command to sepecify alternate  labeling  and  then
202       use restorecon to put the labels on disk.
203
204       semanage  fcontext  -a  -t varnishlog_var_run_t '/srv/myvarnishlog_con‐
205       tent(/.*)?'
206       restorecon -R -v /srv/myvarnishlog_content
207
208       Note: SELinux often uses regular expressions  to  specify  labels  that
209       match multiple files.
210
211       The following file types are defined for varnishlog:
212
213
214
215       varnishlog_exec_t
216
217       -  Set files with the varnishlog_exec_t type, if you want to transition
218       an executable to the varnishlog_t domain.
219
220
221       Paths:
222            /usr/bin/varnishlog, /usr/bin/varnisncsa
223
224
225       varnishlog_initrc_exec_t
226
227       - Set files with the varnishlog_initrc_exec_t  type,  if  you  want  to
228       transition an executable to the varnishlog_initrc_t domain.
229
230
231       Paths:
232            /etc/rc.d/init.d/varnishlog, /etc/rc.d/init.d/varnishncsa
233
234
235       varnishlog_log_t
236
237       -  Set  files  with the varnishlog_log_t type, if you want to treat the
238       data as varnishlog log data, usually stored under the  /var/log  direc‐
239       tory.
240
241
242
243       varnishlog_var_run_t
244
245       -  Set  files  with the varnishlog_var_run_t type, if you want to store
246       the varnishlog files under the /run or /var/run directory.
247
248
249       Paths:
250            /var/run/varnishlog.pid, /var/run/varnishncsa.pid
251
252
253       Note: File context can be temporarily modified with the chcon  command.
254       If  you want to permanently change the file context you need to use the
255       semanage fcontext command.  This will modify the SELinux labeling data‐
256       base.  You will need to use restorecon to apply the labels.
257
258

COMMANDS

260       semanage  fcontext  can also be used to manipulate default file context
261       mappings.
262
263       semanage permissive can also be used to manipulate  whether  or  not  a
264       process type is permissive.
265
266       semanage  module can also be used to enable/disable/install/remove pol‐
267       icy modules.
268
269       semanage boolean can also be used to manipulate the booleans
270
271
272       system-config-selinux is a GUI tool available to customize SELinux pol‐
273       icy settings.
