6 mailman_queue_selinux - Security Enhanced Linux Policy for the mail‐
7 man_queue processes
8
10 Security-Enhanced Linux secures the mailman_queue processes via flexi‐
11 ble mandatory access control.
12 The mailman_queue processes execute with the mailman_queue_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep mailman_queue_t
20
24 The mailman_queue_t SELinux type can be entered via the mail‐
25 man_queue_exec_t file type.
26 The default entrypoint paths for the mailman_queue_t domain are the
28 following:
29 /etc/cron.(daily|monthly)/mailman, /usr/lib/mailman.*/cron/.*,
31 /usr/lib/mailman.*/bin/qrunner
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 mailman_queue policy is very flexible allowing users to setup their
41 mailman_queue processes in as secure a method as possible.
42 The following process types are defined for mailman_queue:
44 mailman_queue_t
46 Note: semanage permissive -a mailman_queue_t can be used to make the
48 process type mailman_queue_t permissive. SELinux does not deny access
49 to permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required. mail‐
55 man_queue policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run mailman_queue with the
57 tightest access possible.
58 If you want to allow all domains to execute in fips_mode, you must turn
62 on the fips_mode boolean. Enabled by default.
63 setsebool -P fips_mode 1
65 If you want to allow system to run with NIS, you must turn on the
69 nis_enabled boolean. Disabled by default.
70 setsebool -P nis_enabled 1
72
76 The SELinux process type mailman_queue_t can manage files labeled with
77 the following file types. The paths listed are the default paths for
78 these file types. Note the processes UID still need to have DAC per‐
79 missions.

82 /var/log/btmp.*
84 /var/log/faillog.*
85 /var/log/tallylog.*

130 SELinux requires files to have an extended attribute to define the file
131 type.
132 You can see the context of a file using the -Z option to ls
134 Policy governs the access confined processes have to these files.
136 SELinux mailman_queue policy is very flexible allowing users to setup
137 their mailman_queue processes in as secure a method as possible.
138 STANDARD FILE CONTEXT
140 SELinux defines the file context types for the mailman_queue, if you
142 wanted to store files with these types in a different paths, you need
143 to execute the semanage command to specify alternate labeling and then
144 use restorecon to put the labels on disk.
145 semanage fcontext -a -t mailman_queue_exec_t '/srv/mailman_queue/con‐
147 tent(/.*)?'
148 restorecon -R -v /srv/mymailman_queue_content
149 Note: SELinux often uses regular expressions to specify labels that
151 match multiple files.
152 The following file types are defined for mailman_queue:
154 mailman_queue_exec_t
158 - Set files with the mailman_queue_exec_t type, if you want to transi‐
160 tion an executable to the mailman_queue_t domain.
161 Paths:
164 /etc/cron.(daily|monthly)/mailman, /usr/lib/mailman.*/cron/.*,
165 /usr/lib/mailman.*/bin/qrunner
166 mailman_queue_tmp_t
169 - Set files with the mailman_queue_tmp_t type, if you want to store
171 mailman queue temporary files in the /tmp directories.
172 Note: File context can be temporarily modified with the chcon command.
176 If you want to permanently change the file context you need to use the
177 semanage fcontext command. This will modify the SELinux labeling data‐
178 base. You will need to use restorecon to apply the labels.
179
182 semanage fcontext can also be used to manipulate default file context
183 mappings.
184 semanage permissive can also be used to manipulate whether or not a
186 process type is permissive.
187 semanage module can also be used to enable/disable/install/remove pol‐
189 icy modules.
190 semanage boolean can also be used to manipulate the booleans
192 system-config-selinux is a GUI tool available to customize SELinux pol‐
195 icy settings.
