NAME

6       dovecot_selinux  -  Security Enhanced Linux Policy for the dovecot pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

BOOLEANS

53       SELinux policy is customizable based on least access required.  dovecot
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run dovecot with the tightest access possi‐
56       ble.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Disabled by default.
91
92       setsebool -P nscd_use_shm 1
93
94
95

MANAGED FILES

97       The SELinux process type dovecot_t can manage files  labeled  with  the
98       following file types.  The paths listed are the default paths for these
99       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

216       SELinux requires files to have an extended attribute to define the file
217       type.
218
219       You can see the context of a file using the -Z option to ls
220
221       Policy  governs  the  access  confined  processes  have to these files.
222       SELinux dovecot policy is very flexible allowing users to  setup  their
223       dovecot processes in as secure a method as possible.
224
225       EQUIVALENCE DIRECTORIES
226
227
228       dovecot  policy  stores data with multiple different file context types
229       under the /var/log/dovecot directory.  If you would like to  store  the
230       data  in a different directory you can use the semanage command to cre‐
231       ate an equivalence mapping.  If you wanted to store this data under the
232       /srv dirctory you would execute the following command:
233
234       semanage fcontext -a -e /var/log/dovecot /srv/dovecot
235       restorecon -R -v /srv/dovecot
236
237       STANDARD FILE CONTEXT
238
239       SELinux  defines  the file context types for the dovecot, if you wanted
240       to store files with these types in a diffent paths, you need to execute
241       the  semanage  command  to  sepecify  alternate  labeling  and then use
242       restorecon to put the labels on disk.
243
244       semanage  fcontext   -a   -t   dovecot_var_run_t   '/srv/mydovecot_con‐
245       tent(/.*)?'
246       restorecon -R -v /srv/mydovecot_content
247
248       Note:  SELinux  often  uses  regular expressions to specify labels that
249       match multiple files.
250
251       The following file types are defined for dovecot:
252
253
254
255       dovecot_auth_exec_t
256

380       Note:  File context can be temporarily modified with the chcon command.
381       If you want to permanently change the file context you need to use  the
382       semanage fcontext command.  This will modify the SELinux labeling data‐
383       base.  You will need to use restorecon to apply the labels.
384
385

COMMANDS

387       semanage fcontext can also be used to manipulate default  file  context
388       mappings.
389
390       semanage  permissive  can  also  be used to manipulate whether or not a
391       process type is permissive.
392
393       semanage module can also be used to enable/disable/install/remove  pol‐
394       icy modules.
395
396       semanage boolean can also be used to manipulate the booleans
397
398
399       system-config-selinux is a GUI tool available to customize SELinux pol‐
400       icy settings.
