NAME

6       postgrey_selinux - Security Enhanced Linux Policy for the postgrey pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  postgrey  processes  via  flexible
11       mandatory access control.
12
13       The  postgrey  processes  execute with the postgrey_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
17       For example:
18
19       ps -eZ | grep postgrey_t
20
21
22

ENTRYPOINTS

24       The postgrey_t SELinux type can be entered via the postgrey_exec_t file
25       type.
26
27       The default entrypoint paths for the postgrey_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/postgrey
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       postgrey policy is very flexible allowing users to setup their postgrey
40       processes in as secure a method as possible.
41
42       The following process types are defined for postgrey:
43
44       postgrey_t
45
46       Note: semanage permissive -a postgrey_t can be used to make the process
47       type  postgrey_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.  post‐
54       grey policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run postgrey with the tightest access
56       possible.
57
58
59
60       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
61       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
62       Enabled by default.
63
64       setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to  allow  system  to run with NIS, you must turn on the
76       nis_enabled boolean. Disabled by default.
77
78       setsebool -P nis_enabled 1
79
80
81

PORT TYPES

83       SELinux defines port types to represent TCP and UDP ports.
84
85       You can see the types associated with a port  by  using  the  following
86       command:
87
88       semanage port -l
89
90
91       Policy  governs  the  access  confined  processes  have to these ports.
92       SELinux postgrey policy is very flexible allowing users to setup  their
93       postgrey processes in as secure a method as possible.
94
95       The following port types are defined for postgrey:
96
97
98       postgrey_port_t
99
100
101
102       Default Defined Ports:
103                 tcp 60000
104

MANAGED FILES

106       The  SELinux  process type postgrey_t can manage files labeled with the
107       following file types.  The paths listed are the default paths for these
108       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

178       SELinux requires files to have an extended attribute to define the file
179       type.
180
181       You can see the context of a file using the -Z option to ls
182
183       Policy governs the access  confined  processes  have  to  these  files.
184       SELinux  postgrey policy is very flexible allowing users to setup their
185       postgrey processes in as secure a method as possible.
186
187       EQUIVALENCE DIRECTORIES
188
189
190       postgrey policy stores data with multiple different file context  types
191       under  the /var/run/postgrey directory.  If you would like to store the
192       data in a different directory you can use the semanage command to  cre‐
193       ate an equivalence mapping.  If you wanted to store this data under the
194       /srv directory you would execute the following command:
195
196       semanage fcontext -a -e /var/run/postgrey /srv/postgrey
197       restorecon -R -v /srv/postgrey
198
199       STANDARD FILE CONTEXT
200
201       SELinux defines the file context types for the postgrey, if you  wanted
202       to  store files with these types in a different paths, you need to exe‐
203       cute the semanage command to specify alternate labeling  and  then  use
204       restorecon to put the labels on disk.
205
206       semanage fcontext -a -t postgrey_exec_t '/srv/postgrey/content(/.*)?'
207       restorecon -R -v /srv/mypostgrey_content
208
209       Note:  SELinux  often  uses  regular expressions to specify labels that
210       match multiple files.
211
212       The following file types are defined for postgrey:
213
214
215
216       postgrey_etc_t
217
218       - Set files with the postgrey_etc_t type, if you want to store postgrey
219       files in the /etc directories.
220
221
222
223       postgrey_exec_t
224
225       - Set files with the postgrey_exec_t type, if you want to transition an
226       executable to the postgrey_t domain.
227
228
229
230       postgrey_initrc_exec_t
231
232       - Set files with the postgrey_initrc_exec_t type, if you want to  tran‐
233       sition an executable to the postgrey_initrc_t domain.
234
235
236
237       postgrey_spool_t
238
239       -  Set  files  with the postgrey_spool_t type, if you want to store the
240       postgrey files under the /var/spool directory.
241
242
243
244       postgrey_var_lib_t
245
246       - Set files with the postgrey_var_lib_t type, if you want to store  the
247       postgrey files under the /var/lib directory.
248
249
250
251       postgrey_var_run_t
252
253       -  Set files with the postgrey_var_run_t type, if you want to store the
254       postgrey files under the /run or /var/run directory.
255
256
257       Paths:
258            /var/run/postgrey(/.*)?, /var/run/postgrey.pid
259
260
261       Note: File context can be temporarily modified with the chcon  command.
262       If  you want to permanently change the file context you need to use the
263       semanage fcontext command.  This will modify the SELinux labeling data‐
264       base.  You will need to use restorecon to apply the labels.
265
266

COMMANDS

268       semanage  fcontext  can also be used to manipulate default file context
269       mappings.
270
271       semanage permissive can also be used to manipulate  whether  or  not  a
272       process type is permissive.
273
274       semanage  module can also be used to enable/disable/install/remove pol‐
275       icy modules.
276
277       semanage port can also be used to manipulate the port definitions
278
279       semanage boolean can also be used to manipulate the booleans
280
281
282       system-config-selinux is a GUI tool available to customize SELinux pol‐
283       icy settings.
