NAME

6       postfix_map_selinux  -  Security  Enhanced  Linux  Policy for the post‐
7       fix_map processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the postfix_map processes via  flexible
11       mandatory access control.
12
13       The  postfix_map processes execute with the postfix_map_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 postfix_map_t

ENTRYPOINTS

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

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  post‐
54       fix_map policy is extremely flexible  and  has  several  booleans  that
55       allow  you to manipulate the policy and run postfix_map with the tight‐
56       est 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. Disabled by default.
91
92       setsebool -P nscd_use_shm 1

MANAGED FILES

97       The SELinux process type postfix_map_t can manage  files  labeled  with
98       the  following  file types.  The paths listed are the default paths for
99       these file types.  Note the processes UID still need to have  DAC  per‐
100       missions.
101
102       mailman_data_t
103
104            /etc/mailman.*
105            /var/lib/mailman(/.*)?
106            /var/spool/mailman.*
107
108       postfix_etc_t
109
110            /etc/postfix.*
111
112       postfix_map_tmp_t
113
114
115

FILE CONTEXTS

117       SELinux requires files to have an extended attribute to define the file
118       type.
119
120       You can see the context of a file using the -Z option to ls
121
122       Policy governs the access  confined  processes  have  to  these  files.
123       SELinux  postfix_map  policy  is  very flexible allowing users to setup
124       their postfix_map processes in as secure a method as possible.
125
126       STANDARD FILE CONTEXT
127
128       SELinux defines the file context types  for  the  postfix_map,  if  you
129       wanted  to store files with these types in a diffent paths, you need to
130       execute the semanage command to sepecify alternate  labeling  and  then
131       use restorecon to put the labels on disk.
132
133       semanage  fcontext  -a  -t  postfix_map_tmp_t  '/srv/mypostfix_map_con‐
134       tent(/.*)?'
135       restorecon -R -v /srv/mypostfix_map_content
136
137       Note: SELinux often uses regular expressions  to  specify  labels  that
138       match multiple files.
139
140       The following file types are defined for postfix_map:
141
142
143
144       postfix_map_exec_t
145
146       - Set files with the postfix_map_exec_t type, if you want to transition
147       an executable to the postfix_map_t domain.
148
149
150
151       postfix_map_tmp_t
152
153       - Set files with the postfix_map_tmp_t type, if you want to store post‐
154       fix map temporary files in the /tmp directories.
155
156
157
158       Note:  File context can be temporarily modified with the chcon command.
159       If you want to permanently change the file context you need to use  the
160       semanage fcontext command.  This will modify the SELinux labeling data‐
161       base.  You will need to use restorecon to apply the labels.

163

COMMANDS

165       semanage fcontext can also be used to manipulate default  file  context
166       mappings.
167
168       semanage  permissive  can  also  be used to manipulate whether or not a
169       process type is permissive.
170
171       semanage module can also be used to enable/disable/install/remove  pol‐
172       icy modules.
173
174       semanage boolean can also be used to manipulate the booleans
175
176
177       system-config-selinux is a GUI tool available to customize SELinux pol‐
178       icy settings.
