NAME

6       spamc_selinux - Security Enhanced Linux Policy for the spamc processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the spamc processes via flexible manda‐
10       tory access control.
11
12       The spamc processes execute with the  spamc_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 spamc_t
19
20
21

ENTRYPOINTS

23       The spamc_t SELinux type can be entered via the spamc_exec_t file type.
24
25       The default entrypoint paths for the spamc_t domain are the following:
26
27       /usr/bin/razor.*,  /usr/bin/pyzor,  /usr/bin/spamc,  /usr/bin/sa-learn,
28       /usr/bin/spamassassin
29

PROCESS TYPES

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

BOOLEANS

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

MANAGED FILES

101       The SELinux process type spamc_t can manage files labeled with the fol‐
102       lowing  file  types.   The paths listed are the default paths for these
103       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

152       SELinux requires files to have an extended attribute to define the file
153       type.
154
155       You can see the context of a file using the -Z option to ls
156
157       Policy  governs  the  access  confined  processes  have to these files.
158       SELinux spamc policy is very flexible allowing  users  to  setup  their
159       spamc processes in as secure a method as possible.
160
161       STANDARD FILE CONTEXT
162
163       SELinux  defines the file context types for the spamc, if you wanted to
164       store files with these types in a diffent paths, you  need  to  execute
165       the  semanage  command  to  sepecify  alternate  labeling  and then use
166       restorecon to put the labels on disk.
167
168       semanage fcontext -a -t spamc_tmp_t '/srv/myspamc_content(/.*)?'
169       restorecon -R -v /srv/myspamc_content
170
171       Note: SELinux often uses regular expressions  to  specify  labels  that
172       match multiple files.
173
174       The following file types are defined for spamc:
175
176
177
178       spamc_exec_t
179
180       -  Set  files  with the spamc_exec_t type, if you want to transition an
181       executable to the spamc_t domain.
182
183
184       Paths:
185            /usr/bin/razor.*,  /usr/bin/pyzor,  /usr/bin/spamc,   /usr/bin/sa-
186            learn, /usr/bin/spamassassin
187
188
189       spamc_home_t
190
191       -  Set  files  with  the  spamc_home_t type, if you want to store spamc
192       files in the users home directory.
193
194
195       Paths:
196            /root/.pyzor(/.*)?,    /root/.razor(/.*)?,     /root/.spamd(/.*)?,
197            /root/.spamassassin(/.*)?,               /home/[^/]+/.pyzor(/.*)?,
198            /home/[^/]+/.razor(/.*)?,                /home/[^/]+/.spamd(/.*)?,
199            /home/[^/]+/.spamassassin(/.*)?
200
201
202       spamc_tmp_t
203
204       -  Set files with the spamc_tmp_t type, if you want to store spamc tem‐
205       porary files in the /tmp directories.
206
207
208
209       Note: File context can be temporarily modified with the chcon  command.
210       If  you want to permanently change the file context you need to use the
211       semanage fcontext command.  This will modify the SELinux labeling data‐
212       base.  You will need to use restorecon to apply the labels.
213
214

COMMANDS

216       semanage  fcontext  can also be used to manipulate default file context
217       mappings.
218
219       semanage permissive can also be used to manipulate  whether  or  not  a
220       process type is permissive.
221
222       semanage  module can also be used to enable/disable/install/remove pol‐
223       icy modules.
224
225       semanage boolean can also be used to manipulate the booleans
226
227
228       system-config-selinux is a GUI tool available to customize SELinux pol‐
229       icy settings.
