NAME

6       postfix_cleanup_selinux  - Security Enhanced Linux Policy for the post‐
7       fix_cleanup processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the postfix_cleanup processes via flex‐
11       ible mandatory access control.
12
13       The   postfix_cleanup  processes  execute  with  the  postfix_cleanup_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_cleanup_t
20

22

ENTRYPOINTS

24       The  postfix_cleanup_t  SELinux  type  can  be  entered  via  the post‐
25       fix_cleanup_exec_t file type.
26
27       The default entrypoint paths for the postfix_cleanup_t domain  are  the
28       following:
29
30       /usr/libexec/postfix/cleanup
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_cleanup  policy  is very flexible allowing users to setup their
40       postfix_cleanup processes in as secure a method as possible.
41
42       The following process types are defined for postfix_cleanup:
43
44       postfix_cleanup_t
45
46       Note: semanage permissive -a postfix_cleanup_t can be used to make  the
47       process type postfix_cleanup_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_cleanup policy is extremely flexible and has several booleans  that
55       allow  you  to  manipulate  the policy and run postfix_cleanup with the
56       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 confined applications to use nscd  shared  memory,
111       you must turn on the nscd_use_shm boolean. Enabled by default.
112
113       setsebool -P nscd_use_shm 1
114
115

MANAGED FILES

118       The  SELinux  process  type  postfix_cleanup_t can manage files labeled
119       with the following file types.  The paths listed are the default  paths
120       for  these  file  types.  Note the processes UID still need to have DAC
121       permissions.
122
123       anon_inodefs_t
124
125
126       initrc_tmp_t

FILE CONTEXTS

165       SELinux requires files to have an extended attribute to define the file
166       type.
167
168       You can see the context of a file using the -Z option to ls
169
170       Policy  governs  the  access  confined  processes  have to these files.
171       SELinux postfix_cleanup policy is very flexible allowing users to setup
172       their postfix_cleanup processes in as secure a method as possible.
173
174       STANDARD FILE CONTEXT
175
176       SELinux  defines the file context types for the postfix_cleanup, if you
177       wanted to store files with these types in a diffent paths, you need  to
178       execute  the  semanage  command to sepecify alternate labeling and then
179       use restorecon to put the labels on disk.
180
181       semanage   fcontext   -a   -t    postfix_cleanup_tmp_t    '/srv/mypost‐
182       fix_cleanup_content(/.*)?'
183       restorecon -R -v /srv/mypostfix_cleanup_content
184
185       Note:  SELinux  often  uses  regular expressions to specify labels that
186       match multiple files.
187
188       The following file types are defined for postfix_cleanup:
189
190
191
192       postfix_cleanup_exec_t
193
194       - Set files with the postfix_cleanup_exec_t type, if you want to  tran‐
195       sition an executable to the postfix_cleanup_t domain.
196
197
198
199       postfix_cleanup_tmp_t
200
201       -  Set  files with the postfix_cleanup_tmp_t type, if you want to store
202       postfix cleanup temporary files in the /tmp directories.
203
204
205
206       Note: File context can be temporarily modified with the chcon  command.
207       If  you want to permanently change the file context you need to use the
208       semanage fcontext command.  This will modify the SELinux labeling data‐
209       base.  You will need to use restorecon to apply the labels.
210
211

COMMANDS

213       semanage  fcontext  can also be used to manipulate default file context
214       mappings.
215
216       semanage permissive can also be used to manipulate  whether  or  not  a
217       process type is permissive.
218
219       semanage  module can also be used to enable/disable/install/remove pol‐
220       icy modules.
221
222       semanage boolean can also be used to manipulate the booleans
223
224
225       system-config-selinux is a GUI tool available to customize SELinux pol‐
226       icy settings.
