NAME

6       postfix_postdrop_selinux - Security Enhanced Linux Policy for the post‐
7       fix_postdrop processes
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  postfix_postdrop  processes  via
11       flexible mandatory access control.
12
13       The  postfix_postdrop  processes  execute  with  the postfix_postdrop_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_postdrop_t

ENTRYPOINTS

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

51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  post‐
54       fix_postdrop policy is extremely flexible and has several booleans that
55       allow  you  to  manipulate the policy and run postfix_postdrop 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_postdrop_t can  manage  files  labeled
76       with  the following file types.  The paths listed are the default paths
77       for these file types.  Note the processes UID still need  to  have  DAC
78       permissions.
79
80       anon_inodefs_t
81
82
83       postfix_spool_t
84
85            /var/spool/postfix.*
86            /var/spool/postfix/defer(/.*)?
87            /var/spool/postfix/flush(/.*)?
88            /var/spool/postfix/deferred(/.*)?
89            /var/spool/postfix/maildrop(/.*)?
90
91       postfix_var_run_t
92
93            /var/spool/postfix/pid/.*
94
95       uucpd_spool_t
96
97            /var/spool/uucp(/.*)?
98            /var/spool/uucppublic(/.*)?

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_postdrop policy is very flexible allowing users to set‐
109       up their postfix_postdrop processes in as secure a method as possible.
110
111       STANDARD FILE CONTEXT
112
113       SELinux defines the file context types for the postfix_postdrop, if you
114       wanted  to store files with these types in a diffent paths, you need to
115       execute the semanage command to sepecify alternate  labeling  and  then
116       use restorecon to put the labels on disk.
117
118       semanage   fcontext   -a  -t  postfix_postdrop_t  '/srv/mypostfix_post‐
119       drop_content(/.*)?'
120       restorecon -R -v /srv/mypostfix_postdrop_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_postdrop:
126
127
128
129       postfix_postdrop_exec_t
130
131       - Set files with the postfix_postdrop_exec_t type, if you want to tran‐
132       sition an executable to the postfix_postdrop_t domain.
133
134
135
136       postfix_postdrop_t
137
138       - Set files with the postfix_postdrop_t type, if you want to treat  the
139       files as postfix postdrop data.
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.
