NAME

6       postfix_pickup_selinux  -  Security Enhanced Linux Policy for the post‐
7       fix_pickup processes
8

DESCRIPTION

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

ENTRYPOINTS

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

51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  post‐
54       fix_pickup policy is extremely flexible and has several  booleans  that
55       allow  you  to  manipulate  the  policy and run postfix_pickup with the
56       tightest 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
64
65
66
67       If  you  want  to  allow  system  to run with NIS, you must turn on the
68       nis_enabled boolean. Disabled by default.
69
70       setsebool -P nis_enabled 1

MANAGED FILES

75       The SELinux process type postfix_pickup_t can manage files labeled with
76       the  following  file types.  The paths listed are the default paths for
77       these file types.  Note the processes UID still need to have  DAC  per‐
78       missions.
79
80       krb5_host_rcache_t
81
82            /var/tmp/krb5_0.rcache2
83            /var/cache/krb5rcache(/.*)?
84            /var/tmp/nfs_0
85            /var/tmp/DNS_25
86            /var/tmp/host_0
87            /var/tmp/imap_0
88            /var/tmp/HTTP_23
89            /var/tmp/HTTP_48
90            /var/tmp/ldap_55
91            /var/tmp/ldap_487
92            /var/tmp/ldapmap1_0
93
94       postfix_pickup_tmp_t
95
96
97       postfix_var_run_t
98
99            /var/spool/postfix/pid/.*

FILE CONTEXTS

103       SELinux requires files to have an extended attribute to define the file
104       type.
105
106       You can see the context of a file using the -Z option to ls
107
108       Policy governs the access  confined  processes  have  to  these  files.
109       SELinux  postfix_pickup policy is very flexible allowing users to setup
110       their postfix_pickup processes in as secure a method as possible.
111
112       STANDARD FILE CONTEXT
113
114       SELinux defines the file context types for the postfix_pickup,  if  you
115       wanted  to  store files with these types in a different paths, you need
116       to execute the semanage command to specify alternate labeling and  then
117       use restorecon to put the labels on disk.
118
119       semanage fcontext -a -t postfix_pickup_exec_t '/srv/postfix_pickup/con‐
120       tent(/.*)?'
121       restorecon -R -v /srv/mypostfix_pickup_content
122
123       Note: SELinux often uses regular expressions  to  specify  labels  that
124       match multiple files.
125
126       The following file types are defined for postfix_pickup:
127
128
129
130       postfix_pickup_exec_t
131
132       - Set files with the postfix_pickup_exec_t type, if you want to transi‐
133       tion an executable to the postfix_pickup_t domain.
134
135
136
137       postfix_pickup_tmp_t
138
139       - Set files with the postfix_pickup_tmp_t type, if you  want  to  store
140       postfix pickup temporary files in the /tmp directories.
141
142
143
144       Note:  File context can be temporarily modified with the chcon command.
145       If you want to permanently change the file context you need to use  the
146       semanage fcontext command.  This will modify the SELinux labeling data‐
147       base.  You will need to use restorecon to apply the labels.
148
149

COMMANDS

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