NAME

6       postfix_postqueue_selinux  -  Security  Enhanced  Linux  Policy for the
7       postfix_postqueue processes
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  postfix_postqueue  processes  via
11       flexible mandatory access control.
12
13       The  postfix_postqueue  processes  execute with the postfix_postqueue_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_postqueue_t
20
21
22

ENTRYPOINTS

24       The  postfix_postqueue_t  SELinux  type  can  be  entered via the post‐
25       fix_postqueue_exec_t file type.
26
27       The default entrypoint paths for the postfix_postqueue_t domain are the
28       following:
29
30       /usr/sbin/postqueue
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_postqueue policy is very flexible allowing users to setup their
40       postfix_postqueue processes in as secure a method as possible.
41
42       The following process types are defined for postfix_postqueue:
43
44       postfix_postqueue_t
45
46       Note: semanage permissive -a postfix_postqueue_t can be  used  to  make
47       the  process type postfix_postqueue_t permissive. SELinux does not deny
48       access to permissive process types, but the AVC (SELinux denials)  mes‐
49       sages are still generated.
50
51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  post‐
54       fix_postqueue policy is extremely flexible  and  has  several  booleans
55       that  allow you to manipulate the policy and run postfix_postqueue with
56       the tightest access possible.
57
58
59
60       If you want to allow all domains to use other domains file descriptors,
61       you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63       setsebool -P allow_domain_fd_use 1
64
65
66
67       If  you  want  to allow confined applications to run with kerberos, you
68       must turn on the allow_kerberos boolean. Enabled by default.
69
70       setsebool -P allow_kerberos 1
71
72
73
74       If you want to allow sysadm to debug or ptrace all processes, you  must
75       turn on the allow_ptrace boolean. Disabled by default.
76
77       setsebool -P allow_ptrace 1
78
79
80
81       If  you  want  to  allow  system  to run with NIS, you must turn on the
82       allow_ypbind boolean. Disabled by default.
83
84       setsebool -P allow_ypbind 1
85
86
87
88       If you want to allow all domains to have the kernel load  modules,  you
89       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
90       default.
91
92       setsebool -P domain_kernel_load_modules 1
93
94
95
96       If you want to allow all domains to execute in fips_mode, you must turn
97       on the fips_mode boolean. Enabled by default.
98
99       setsebool -P fips_mode 1
100
101
102
103       If you want to enable reading of urandom for all domains, you must turn
104       on the global_ssp boolean. Disabled by default.
105
106       setsebool -P global_ssp 1
107
108
109
110       If you want to allow http daemon to send mail, you  must  turn  on  the
111       httpd_can_sendmail boolean. Disabled by default.
112
113       setsebool -P httpd_can_sendmail 1
114
115
116
117       If  you  want to allow confined applications to use nscd shared memory,
118       you must turn on the nscd_use_shm boolean. Enabled by default.
119
120       setsebool -P nscd_use_shm 1
121
122

MANAGED FILES

125       The SELinux process type postfix_postqueue_t can manage  files  labeled
126       with  the following file types.  The paths listed are the default paths
127       for these file types.  Note the processes UID still need  to  have  DAC
128       permissions.
129
130       anon_inodefs_t
131
132
133       arpwatch_tmp_t
134
135
136       initrc_tmp_t
137
138
139       mnt_t
140
141            /mnt(/[^/]*)
142            /mnt(/[^/]*)?
143            /rhev(/[^/]*)?
144            /media(/[^/]*)
145            /media(/[^/]*)?

156
157       tmp_t
158
159            /tmp
160            /usr/tmp
161            /var/tmp
162            /tmp-inst

FILE CONTEXTS

168       SELinux requires files to have an extended attribute to define the file
169       type.
170
171       You can see the context of a file using the -Z option to ls
172
173       Policy governs the access  confined  processes  have  to  these  files.
174       SELinux  postfix_postqueue  policy  is  very flexible allowing users to
175       setup their postfix_postqueue processes in as secure a method as possi‐
176       ble.
177
178       The following file types are defined for postfix_postqueue:
179
180
181
182       postfix_postqueue_exec_t
183
184       -  Set  files  with  the  postfix_postqueue_exec_t type, if you want to
185       transition an executable to the postfix_postqueue_t domain.
186
187
188
189       Note: File context can be temporarily modified with the chcon  command.
190       If  you want to permanently change the file context you need to use the
191       semanage fcontext command.  This will modify the SELinux labeling data‐
192       base.  You will need to use restorecon to apply the labels.
193
194

COMMANDS

196       semanage  fcontext  can also be used to manipulate default file context
197       mappings.
198
199       semanage permissive can also be used to manipulate  whether  or  not  a
200       process type is permissive.
201
202       semanage  module can also be used to enable/disable/install/remove pol‐
203       icy modules.
204
205       semanage boolean can also be used to manipulate the booleans
206
207
208       system-config-selinux is a GUI tool available to customize SELinux pol‐
209       icy settings.
