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.
50
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
71

73

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       anon_inodefs_t
81
82
83       postfix_var_run_t
84
85            /var/spool/postfix/pid/.*
86
87

FILE CONTEXTS

89       SELinux requires files to have an extended attribute to define the file
90       type.
91
92       You can see the context of a file using the -Z option to ls
93
94       Policy governs the access  confined  processes  have  to  these  files.
95       SELinux  postfix_pickup policy is very flexible allowing users to setup
96       their postfix_pickup processes in as secure a method as possible.
97
98       STANDARD FILE CONTEXT
99
100       SELinux defines the file context types for the postfix_pickup,  if  you
101       wanted  to store files with these types in a diffent paths, you need to
102       execute the semanage command to sepecify alternate  labeling  and  then
103       use restorecon to put the labels on disk.
104
105       semanage    fcontext    -a    -t   postfix_pickup_tmp_t   '/srv/mypost‐
106       fix_pickup_content(/.*)?'
107       restorecon -R -v /srv/mypostfix_pickup_content
108
109       Note: SELinux often uses regular expressions  to  specify  labels  that
110       match multiple files.
111
112       The following file types are defined for postfix_pickup:
113
114
115
116       postfix_pickup_exec_t
117
118       - Set files with the postfix_pickup_exec_t type, if you want to transi‐
119       tion an executable to the postfix_pickup_t domain.
120
121
122
123       postfix_pickup_tmp_t
124
125       - Set files with the postfix_pickup_tmp_t type, if you  want  to  store
126       postfix pickup temporary files in the /tmp directories.
127
128
129
130       Note:  File context can be temporarily modified with the chcon command.
131       If you want to permanently change the file context you need to use  the
132       semanage fcontext command.  This will modify the SELinux labeling data‐
133       base.  You will need to use restorecon to apply the labels.
134
135

COMMANDS

137       semanage fcontext can also be used to manipulate default  file  context
138       mappings.
139
140       semanage  permissive  can  also  be used to manipulate whether or not a
141       process type is permissive.
142
143       semanage module can also be used to enable/disable/install/remove  pol‐
144       icy modules.
145
146       semanage boolean can also be used to manipulate the booleans
147
148
149       system-config-selinux is a GUI tool available to customize SELinux pol‐
150       icy settings.
