NAME

6       spamd_selinux - Security Enhanced Linux Policy for the spamd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The spamd_t SELinux type can be entered via the spamd_exec_t file type.
24
25       The default entrypoint paths for the spamd_t domain are the following:
26
27       /usr/bin/spamd,  /usr/bin/pyzord,  /usr/sbin/spamd,   /usr/sbin/spampd,
28       /usr/bin/mimedefang,                   /usr/bin/mimedefang-multiplexor,
29       /usr/libexec/mimedefang-wrapper

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       spamd policy is very flexible allowing users to setup their spamd  pro‐
39       cesses in as secure a method as possible.
40
41       The following process types are defined for spamd:
42
43       spamd_update_t, spamd_t
44
45       Note:  semanage  permissive  -a spamd_t can be used to make the process
46       type spamd_t permissive. SELinux does not  deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.
49
50

BOOLEANS

52       SELinux policy is customizable based on least access  required.   spamd
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run spamd with the tightest access possible.
55
56
57
58       If you want to allow spamd to read/write  user  home  directories,  you
59       must turn on the spamd_enable_home_dirs boolean. Enabled by default.
60
61       setsebool -P spamd_enable_home_dirs 1
62
63
64
65       If you want to allow users to resolve user passwd entries directly from
66       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
67       gin_nsswitch_use_ldap boolean. Disabled by default.
68
69       setsebool -P authlogin_nsswitch_use_ldap 1
70
71
72
73       If you want to allow all domains to execute in fips_mode, you must turn
74       on the fips_mode boolean. Enabled by default.
75
76       setsebool -P fips_mode 1
77
78
79
80       If you want to allow confined applications to run  with  kerberos,  you
81       must turn on the kerberos_enabled boolean. Enabled by default.
82
83       setsebool -P kerberos_enabled 1
84
85
86
87       If  you  want  to  allow  system  to run with NIS, you must turn on the
88       nis_enabled boolean. Disabled by default.
89
90       setsebool -P nis_enabled 1
91
92
93
94       If you want to allow confined applications to use nscd  shared  memory,
95       you must turn on the nscd_use_shm boolean. Disabled by default.
96
97       setsebool -P nscd_use_shm 1
98
99
100

PORT TYPES

102       SELinux defines port types to represent TCP and UDP ports.
103
104       You  can  see  the  types associated with a port by using the following
105       command:
106
107       semanage port -l
108
109
110       Policy governs the access  confined  processes  have  to  these  ports.
111       SELinux  spamd  policy  is  very flexible allowing users to setup their
112       spamd processes in as secure a method as possible.
113
114       The following port types are defined for spamd:
115
116
117       spamd_port_t
118
119
120
121       Default Defined Ports:
122                 tcp 783,10026,10027
123

MANAGED FILES

125       The SELinux process type spamd_t can manage files labeled with the fol‐
126       lowing  file  types.   The paths listed are the default paths for these
127       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

266       SELinux requires files to have an extended attribute to define the file
267       type.
268
269       You can see the context of a file using the -Z option to ls
270
271       Policy  governs  the  access  confined  processes  have to these files.
272       SELinux spamd policy is very flexible allowing  users  to  setup  their
273       spamd processes in as secure a method as possible.
274
275       EQUIVALENCE DIRECTORIES
276
277
278       spamd  policy  stores  data  with multiple different file context types
279       under the /var/lib/spamassassin directory.  If you would like to  store
280       the  data  in a different directory you can use the semanage command to
281       create an equivalence mapping.  If you wanted to store this data  under
282       the /srv dirctory you would execute the following command:
283
284       semanage fcontext -a -e /var/lib/spamassassin /srv/spamassassin
285       restorecon -R -v /srv/spamassassin
286
287       STANDARD FILE CONTEXT
288
289       SELinux  defines the file context types for the spamd, if you wanted to
290       store files with these types in a diffent paths, you  need  to  execute
291       the  semanage  command  to  sepecify  alternate  labeling  and then use
292       restorecon to put the labels on disk.
293
294       semanage fcontext -a -t spamd_etc_t '/srv/myspamd_content(/.*)?'
295       restorecon -R -v /srv/myspamd_content
296
297       Note: SELinux often uses regular expressions  to  specify  labels  that
298       match multiple files.
299
300       The following file types are defined for spamd:
301
302
303
304       spamd_compiled_t
305
306       -  Set  files  with the spamd_compiled_t type, if you want to treat the

310
311       spamd_etc_t
312

348
349
350       Paths:
351            /var/log/spamd.log.*,                       /var/log/mimedefang.*,
352            /var/log/pyzord.log.*, /var/log/razor-agent.log.*
353
354
355       spamd_spool_t
356
357       - Set files with the spamd_spool_t type, if you want to store the spamd
358       files under the /var/spool directory.

369       porary files in the /tmp directories.
370

372
373       spamd_update_exec_t
374

376       tion an executable to the spamd_update_t domain.
377
378
379       Paths:
380            /usr/share/spamassassin/sa-update.cron, /usr/bin/sa-update
381
382
383       spamd_var_lib_t

403
404
405       Note: File context can be temporarily modified with the chcon  command.
406       If  you want to permanently change the file context you need to use the
407       semanage fcontext command.  This will modify the SELinux labeling data‐
408       base.  You will need to use restorecon to apply the labels.
409
410

COMMANDS

412       semanage  fcontext  can also be used to manipulate default file context
413       mappings.
414
415       semanage permissive can also be used to manipulate  whether  or  not  a
416       process type is permissive.
417
418       semanage  module can also be used to enable/disable/install/remove pol‐
419       icy modules.
420
421       semanage port can also be used to manipulate the port definitions
422
423       semanage boolean can also be used to manipulate the booleans
424
425
426       system-config-selinux is a GUI tool available to customize SELinux pol‐
427       icy settings.
