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 users to resolve user passwd entries directly from
62 ldap rather then using a sssd server, you must turn on the authlo‐
63 gin_nsswitch_use_ldap boolean. Disabled by default.
64 setsebool -P authlogin_nsswitch_use_ldap 1
66 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71 setsebool -P fips_mode 1
73 If you want to allow confined applications to run with kerberos, you
77 must turn on the kerberos_enabled boolean. Enabled by default.
78 setsebool -P kerberos_enabled 1
80 If you want to allow system to run with NIS, you must turn on the
84 nis_enabled boolean. Disabled by default.
85 setsebool -P nis_enabled 1
87 If you want to allow confined applications to use nscd shared memory,
91 you must turn on the nscd_use_shm boolean. Disabled by default.
92 setsebool -P nscd_use_shm 1
94
98 The SELinux process type mailman_queue_t can manage files labeled with
99 the following file types. The paths listed are the default paths for
100 these file types. Note the processes UID still need to have DAC per‐
101 missions.
102 faillog_t
104 /var/log/btmp.*
106 /var/log/faillog.*
107 /var/log/tallylog.*
108 /var/run/faillock(/.*)?
109 fusefs_t
111 /var/run/user/[^/]*/gvfs
113 mailman_archive_t
115 /var/lib/mailman.*/archives(/.*)?
117 mailman_data_t
119 /etc/mailman.*
121 /var/lib/mailman(/.*)?
122 /var/spool/mailman.*
123 mailman_lock_t
125 /var/lock/mailman.*
127 /var/lock/subsys/mailman.*
128 mailman_log_t
130 /var/log/mailman.*
132 mailman_queue_tmp_t
134
138 SELinux requires files to have an extended attribute to define the file
139 type.
140 You can see the context of a file using the -Z option to ls
142 Policy governs the access confined processes have to these files.
144 SELinux mailman_queue policy is very flexible allowing users to setup
145 their mailman_queue processes in as secure a method as possible.
146 STANDARD FILE CONTEXT
148 SELinux defines the file context types for the mailman_queue, if you
150 wanted to store files with these types in a diffent paths, you need to
151 execute the semanage command to sepecify alternate labeling and then
152 use restorecon to put the labels on disk.
153 semanage fcontext -a -t mailman_queue_tmp_t '/srv/mymailman_queue_con‐
155 tent(/.*)?'
156 restorecon -R -v /srv/mymailman_queue_content
157 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160 The following file types are defined for mailman_queue:
162 mailman_queue_exec_t
166 - Set files with the mailman_queue_exec_t type, if you want to transi‐
168 tion an executable to the mailman_queue_t domain.
169 Paths:
172 /etc/cron.(daily|monthly)/mailman, /usr/lib/mailman.*/cron/.*,
173 /usr/lib/mailman.*/bin/qrunner
174 mailman_queue_tmp_t
177 - Set files with the mailman_queue_tmp_t type, if you want to store
179 mailman queue temporary files in the /tmp directories.
180 Note: File context can be temporarily modified with the chcon command.
184 If you want to permanently change the file context you need to use the
185 semanage fcontext command. This will modify the SELinux labeling data‐
186 base. You will need to use restorecon to apply the labels.
187
190 semanage fcontext can also be used to manipulate default file context
191 mappings.
192 semanage permissive can also be used to manipulate whether or not a
194 process type is permissive.
195 semanage module can also be used to enable/disable/install/remove pol‐
197 icy modules.
198 semanage boolean can also be used to manipulate the booleans
200 system-config-selinux is a GUI tool available to customize SELinux pol‐
203 icy settings.
