NAME

6       mailman_cgi_selinux  -  Security  Enhanced  Linux  Policy for the mail‐
7       man_cgi processes
8

DESCRIPTION

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

22

ENTRYPOINTS

24       The   mailman_cgi_t   SELinux   type  can  be  entered  via  the  mail‐
25       man_cgi_exec_t file type.
26
27       The default entrypoint paths for the mailman_cgi_t domain are the  fol‐
28       lowing:
29
30       /usr/lib/mailman.*/cgi-bin/.*, /usr/lib/cgi-bin/mailman.*/.*
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       mailman_cgi policy is very flexible allowing users to setup their mail‐
40       man_cgi processes in as secure a method as possible.
41
42       The following process types are defined for mailman_cgi:
43
44       mailman_cgi_t
45
46       Note: semanage permissive -a mailman_cgi_t can  be  used  to  make  the
47       process  type mailman_cgi_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.  mail‐
54       man_cgi policy is extremely flexible  and  has  several  booleans  that
55       allow  you to manipulate the policy and run mailman_cgi with the tight‐
56       est access possible.
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

68       If you want to deny any process from ptracing or  debugging  any  other
69       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
70       default.
71

MANAGED FILES

150       The  SELinux  process  type mailman_cgi_t can manage files labeled with
151       the following file types.  The paths listed are the default  paths  for
152       these  file  types.  Note the processes UID still need to have DAC per‐
153       missions.
154
155       fusefs_t
156
157            /var/run/user/[^/]*/gvfs
158
159       mailman_archive_t
160
161            /var/lib/mailman.*/archives(/.*)?
162
163       mailman_cgi_tmp_t
164
165
166       mailman_data_t
167
168            /etc/mailman.*
169            /var/lib/mailman(/.*)?
170            /var/spool/mailman.*
171
172       mailman_lock_t
173
174            /var/lock/mailman.*
175            /var/lock/subsys/mailman.*
176
177       mailman_log_t
178
179            /var/log/mailman.*

FILE CONTEXTS

183       SELinux requires files to have an extended attribute to define the file
184       type.
185
186       You can see the context of a file using the -Z option to ls
187
188       Policy  governs  the  access  confined  processes  have to these files.
189       SELinux mailman_cgi policy is very flexible  allowing  users  to  setup
190       their mailman_cgi processes in as secure a method as possible.
191
192       STANDARD FILE CONTEXT
193
194       SELinux  defines  the  file  context  types for the mailman_cgi, if you
195       wanted to store files with these types in a diffent paths, you need  to
196       execute  the  semanage  command to sepecify alternate labeling and then
197       use restorecon to put the labels on disk.
198
199       semanage  fcontext  -a  -t  mailman_cgi_tmp_t  '/srv/mymailman_cgi_con‐
200       tent(/.*)?'
201       restorecon -R -v /srv/mymailman_cgi_content
202
203       Note:  SELinux  often  uses  regular expressions to specify labels that
204       match multiple files.
205
206       The following file types are defined for mailman_cgi:
207
208
209
210       mailman_cgi_exec_t
211
212       - Set files with the mailman_cgi_exec_t type, if you want to transition
213       an executable to the mailman_cgi_t domain.
214
215
216       Paths:
217            /usr/lib/mailman.*/cgi-bin/.*, /usr/lib/cgi-bin/mailman.*/.*
218
219
220       mailman_cgi_tmp_t
221
222       - Set files with the mailman_cgi_tmp_t type, if you want to store mail‐
223       man cgi temporary files in the /tmp directories.
224
225
226
227       Note: File context can be temporarily modified with the chcon  command.
228       If  you want to permanently change the file context you need to use the
229       semanage fcontext command.  This will modify the SELinux labeling data‐
230       base.  You will need to use restorecon to apply the labels.
231
232

COMMANDS

234       semanage  fcontext  can also be used to manipulate default file context
235       mappings.
236
237       semanage permissive can also be used to manipulate  whether  or  not  a
238       process type is permissive.
239
240       semanage  module can also be used to enable/disable/install/remove pol‐
241       icy modules.
242
243       semanage boolean can also be used to manipulate the booleans
244
245
246       system-config-selinux is a GUI tool available to customize SELinux pol‐
247       icy settings.
