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 dontaudit all  daemons  scheduling  requests  (setsched,
61       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
62       Enabled by default.
63
64       setsebool -P daemons_dontaudit_scheduling 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

MANAGED FILES

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

FILE CONTEXTS

211       SELinux requires files to have an extended attribute to define the file
212       type.
213
214       You can see the context of a file using the -Z option to ls
215
216       Policy governs the access  confined  processes  have  to  these  files.
217       SELinux  dovecot  policy is very flexible allowing users to setup their
218       dovecot processes in as secure a method as possible.
219
220       EQUIVALENCE DIRECTORIES
221
222
223       dovecot policy stores data with multiple different file  context  types
224       under  the  /var/log/dovecot directory.  If you would like to store the
225       data in a different directory you can use the semanage command to  cre‐
226       ate an equivalence mapping.  If you wanted to store this data under the
227       /srv directory you would execute the following command:
228
229       semanage fcontext -a -e /var/log/dovecot /srv/dovecot
230       restorecon -R -v /srv/dovecot
231
232       STANDARD FILE CONTEXT
233
234       SELinux defines the file context types for the dovecot, if  you  wanted
235       to  store files with these types in a different paths, you need to exe‐
236       cute the semanage command to specify alternate labeling  and  then  use
237       restorecon to put the labels on disk.
238
239       semanage fcontext -a -t dovecot_exec_t '/srv/dovecot/content(/.*)?'
240       restorecon -R -v /srv/mydovecot_content
241
242       Note:  SELinux  often  uses  regular expressions to specify labels that
243       match multiple files.
244
245       The following file types are defined for dovecot:
246
247
248
249       dovecot_auth_exec_t

372
373
374       Note:  File context can be temporarily modified with the chcon command.
375       If you want to permanently change the file context you need to use  the
376       semanage fcontext command.  This will modify the SELinux labeling data‐
377       base.  You will need to use restorecon to apply the labels.
378
379

COMMANDS

381       semanage fcontext can also be used to manipulate default  file  context
382       mappings.
383
384       semanage  permissive  can  also  be used to manipulate whether or not a
385       process type is permissive.
386
387       semanage module can also be used to enable/disable/install/remove  pol‐
388       icy modules.
389
390       semanage boolean can also be used to manipulate the booleans
391
392
393       system-config-selinux is a GUI tool available to customize SELinux pol‐
394       icy settings.
