NAME

6       fetchmail_selinux  -  Security  Enhanced Linux Policy for the fetchmail
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the fetchmail  processes  via  flexible
11       mandatory access control.
12
13       The  fetchmail processes execute with the fetchmail_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep fetchmail_t
20
21
22

ENTRYPOINTS

24       The  fetchmail_t  SELinux  type can be entered via the fetchmail_exec_t
25       file type.
26
27       The default entrypoint paths for the fetchmail_t domain are the follow‐
28       ing:
29
30       /usr/bin/fetchmail
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       fetchmail  policy is very flexible allowing users to setup their fetch‐
40       mail processes in as secure a method as possible.
41
42       The following process types are defined for fetchmail:
43
44       fetchmail_t
45
46       Note: semanage permissive -a  fetchmail_t  can  be  used  to  make  the
47       process  type  fetchmail_t  permissive. SELinux does not deny access to
48       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.  fetch‐
54       mail policy is extremely flexible and has several booleans  that  allow
55       you to manipulate the policy and run fetchmail with the tightest access
56       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 confined applications to run with kerberos, you
68       must turn on the kerberos_enabled boolean. Disabled by default.
69
70       setsebool -P kerberos_enabled 1
71
72
73
74       If you want to allow confined applications to use nscd  shared  memory,
75       you must turn on the nscd_use_shm boolean. Disabled by default.
76
77       setsebool -P nscd_use_shm 1
78

MANAGED FILES

82       The  SELinux process type fetchmail_t can manage files labeled with the
83       following file types.  The paths listed are the default paths for these
84       file types.  Note the processes UID still need to have DAC permissions.
85
86       cluster_conf_t

FILE CONTEXTS

138       SELinux requires files to have an extended attribute to define the file
139       type.
140
141       You can see the context of a file using the -Z option to ls
142
143       Policy governs the access  confined  processes  have  to  these  files.
144       SELinux fetchmail policy is very flexible allowing users to setup their
145       fetchmail processes in as secure a method as possible.
146
147       STANDARD FILE CONTEXT
148
149       SELinux defines the file context types for the fetchmail, if you wanted
150       to store files with these types in a diffent paths, you need to execute
151       the semanage command  to  sepecify  alternate  labeling  and  then  use
152       restorecon to put the labels on disk.
153
154       semanage  fcontext  -a -t fetchmail_uidl_cache_t '/srv/myfetchmail_con‐
155       tent(/.*)?'
156       restorecon -R -v /srv/myfetchmail_content
157
158       Note: SELinux often uses regular expressions  to  specify  labels  that
159       match multiple files.
160
161       The following file types are defined for fetchmail:
162
163
164
165       fetchmail_etc_t
166
167       -  Set files with the fetchmail_etc_t type, if you want to store fetch‐
168       mail files in the /etc directories.
169
170
171
172       fetchmail_exec_t
173
174       - Set files with the fetchmail_exec_t type, if you want  to  transition
175       an executable to the fetchmail_t domain.
176
177
178
179       fetchmail_home_t
180
181       - Set files with the fetchmail_home_t type, if you want to store fetch‐
182       mail files in the users home directory.
183
184
185       Paths:
186            /root/.fetchmailrc, /home/[^/]+/.fetchmailrc
187
188
189       fetchmail_initrc_exec_t
190
191       - Set files with the fetchmail_initrc_exec_t type, if you want to tran‐
192       sition an executable to the fetchmail_initrc_t domain.
193
194
195
196       fetchmail_log_t
197
198       -  Set  files  with  the fetchmail_log_t type, if you want to treat the
199       data as fetchmail log data, usually stored under  the  /var/log  direc‐
200       tory.
201
202
203
204       fetchmail_uidl_cache_t
205
206       -  Set files with the fetchmail_uidl_cache_t type, if you want to store
207       the files under the /var/cache directory.
208
209
210       Paths:
211            /var/lib/fetchmail(/.*)?,                /var/mail/.fetchmail.pid,
212            /var/mail/.fetchmail-UIDL-cache
213
214
215       fetchmail_var_run_t
216
217       - Set files with the fetchmail_var_run_t type, if you want to store the
218       fetchmail files under the /run or /var/run directory.
219
220
221
222       Note: File context can be temporarily modified with the chcon  command.
223       If  you want to permanently change the file context you need to use the
224       semanage fcontext command.  This will modify the SELinux labeling data‐
225       base.  You will need to use restorecon to apply the labels.
226
227

COMMANDS

229       semanage  fcontext  can also be used to manipulate default file context
230       mappings.
231
232       semanage permissive can also be used to manipulate  whether  or  not  a
233       process type is permissive.
234
235       semanage  module can also be used to enable/disable/install/remove pol‐
236       icy modules.
237
238       semanage boolean can also be used to manipulate the booleans
239
240
241       system-config-selinux is a GUI tool available to customize SELinux pol‐
242       icy settings.
