NAME

6       postfix_postqueue_selinux  -  Security  Enhanced  Linux  Policy for the
7       postfix_postqueue processes
8

DESCRIPTION

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

ENTRYPOINTS

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

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  post‐
54       fix_postqueue policy is extremely flexible  and  has  several  booleans
55       that  allow you to manipulate the policy and run postfix_postqueue with
56       the tightest access possible.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Enabled by default.
91
92       setsebool -P nscd_use_shm 1

MANAGED FILES

97       The SELinux process type postfix_postqueue_t can manage  files  labeled
98       with  the following file types.  The paths listed are the default paths
99       for these file types.  Note the processes UID still need  to  have  DAC
100       permissions.
101
102       anon_inodefs_t
103
104
105       arpwatch_tmp_t
106
107
108       postfix_var_run_t
109
110            /var/spool/postfix/pid/.*
111
112

FILE CONTEXTS

114       SELinux requires files to have an extended attribute to define the file
115       type.
116
117       You can see the context of a file using the -Z option to ls
118
119       Policy governs the access  confined  processes  have  to  these  files.
120       SELinux  postfix_postqueue  policy  is  very flexible allowing users to
121       setup their postfix_postqueue processes in as secure a method as possi‐
122       ble.
123
124       The following file types are defined for postfix_postqueue:
125
126
127
128       postfix_postqueue_exec_t
129
130       -  Set  files  with  the  postfix_postqueue_exec_t type, if you want to
131       transition an executable to the postfix_postqueue_t domain.
132
133
134
135       Note: File context can be temporarily modified with the chcon  command.
136       If  you want to permanently change the file context you need to use the
137       semanage fcontext command.  This will modify the SELinux labeling data‐
138       base.  You will need to use restorecon to apply the labels.

140

COMMANDS

142       semanage  fcontext  can also be used to manipulate default file context
143       mappings.
144
145       semanage permissive can also be used to manipulate  whether  or  not  a
146       process type is permissive.
147
148       semanage  module can also be used to enable/disable/install/remove pol‐
149       icy modules.
150
151       semanage boolean can also be used to manipulate the booleans
152
153
154       system-config-selinux is a GUI tool available to customize SELinux pol‐
155       icy settings.
