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  al‐
55       low  you to manipulate the policy and run postfix_map with the tightest
56       access possible.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1

MANAGED FILES

68       The  SELinux  process  type postfix_map_t can manage files labeled with
69       the following file types.  The paths listed are the default  paths  for
70       these  file  types.  Note the processes UID still need to have DAC per‐
71       missions.
72
73       krb5_host_rcache_t
74
75            /var/tmp/krb5_0.rcache2
76            /var/cache/krb5rcache(/.*)?
77            /var/tmp/nfs_0
78            /var/tmp/DNS_25
79            /var/tmp/host_0
80            /var/tmp/imap_0
81            /var/tmp/HTTP_23
82            /var/tmp/HTTP_48
83            /var/tmp/ldap_55
84            /var/tmp/ldap_487
85            /var/tmp/ldapmap1_0
86

88
89            /etc/mailman.*
90            /var/lib/mailman(/.*)?
91            /var/spool/mailman.*

93       postfix_etc_t

FILE CONTEXTS

102       SELinux requires files to have an extended attribute to define the file
103       type.
104
105       You can see the context of a file using the -Z option to ls
106
107       Policy  governs  the  access  confined  processes  have to these files.
108       SELinux postfix_map policy is very flexible  allowing  users  to  setup
109       their postfix_map processes in as secure a method as possible.
110
111       STANDARD FILE CONTEXT
112
113       SELinux  defines  the  file  context  types for the postfix_map, if you
114       wanted to store files with these types in a diffent paths, you need  to
115       execute the semanage command to specify alternate labeling and then use
116       restorecon to put the labels on disk.
117
118       semanage  fcontext  -a  -t  postfix_map_tmp_t  '/srv/mypostfix_map_con‐
119       tent(/.*)?'
120       restorecon -R -v /srv/mypostfix_map_content
121
122       Note:  SELinux  often  uses  regular expressions to specify labels that
123       match multiple files.
124
125       The following file types are defined for postfix_map:
126
127
128
129       postfix_map_exec_t
130
131       - Set files with the postfix_map_exec_t type, if you want to transition
132       an executable to the postfix_map_t domain.
133
134
135
136       postfix_map_tmp_t
137
138       - Set files with the postfix_map_tmp_t type, if you want to store post‐
139       fix map temporary files in the /tmp directories.
140
141
142
143       Note: File context can be temporarily modified with the chcon  command.
144       If  you want to permanently change the file context you need to use the
145       semanage fcontext command.  This will modify the SELinux labeling data‐
146       base.  You will need to use restorecon to apply the labels.
147
148

COMMANDS

150       semanage  fcontext  can also be used to manipulate default file context
151       mappings.
152
153       semanage permissive can also be used to manipulate  whether  or  not  a
154       process type is permissive.
155
156       semanage  module can also be used to enable/disable/install/remove pol‐
157       icy modules.
158
159       semanage boolean can also be used to manipulate the booleans
160
161
162       system-config-selinux is a GUI tool available to customize SELinux pol‐
163       icy settings.
