6 dovecot_deliver_selinux - Security Enhanced Linux Policy for the dove‐
7 cot_deliver processes
8
10 Security-Enhanced Linux secures the dovecot_deliver processes via flex‐
11 ible mandatory access control.
12 The dovecot_deliver processes execute with the dovecot_deliver_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep dovecot_deliver_t
20
24 The dovecot_deliver_t SELinux type can be entered via the dove‐
25 cot_deliver_exec_t file type.
26 The default entrypoint paths for the dovecot_deliver_t domain are the
28 following:
29 /usr/libexec/dovecot/deliver, /usr/libexec/dovecot/dovecot-lda
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 dovecot_deliver policy is very flexible allowing users to setup their
40 dovecot_deliver processes in as secure a method as possible.
41 The following process types are defined for dovecot_deliver:
43 dovecot_deliver_t
45 Note: semanage permissive -a dovecot_deliver_t can be used to make the
47 process type dovecot_deliver_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. dove‐
54 cot_deliver policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run dovecot_deliver with the
56 tightest access possible.
57 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 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91 setsebool -P nscd_use_shm 1
93
97 The SELinux process type dovecot_deliver_t can manage files labeled
98 with the following file types. The paths listed are the default paths
99 for these file types. Note the processes UID still need to have DAC
100 permissions.
101 cifs_t
103 data_home_t
106 /root/.local/share(/.*)?
108 /home/[^/]+/.local/share(/.*)?
109 dovecot_deliver_tmp_t
111 dovecot_spool_t
114 /var/spool/dovecot(/.*)?
116 dovecot_var_log_t
118 /var/log/dovecot(/.*)?
120 /var/log/dovecot.log.*
121 ecryptfs_t
123 /home/[^/]+/.Private(/.*)?
125 /home/[^/]+/.ecryptfs(/.*)?
126 fusefs_t

155 SELinux requires files to have an extended attribute to define the file
156 type.
157 You can see the context of a file using the -Z option to ls
159 Policy governs the access confined processes have to these files.
161 SELinux dovecot_deliver policy is very flexible allowing users to setup
162 their dovecot_deliver processes in as secure a method as possible.
163 STANDARD FILE CONTEXT
165 SELinux defines the file context types for the dovecot_deliver, if you
167 wanted to store files with these types in a diffent paths, you need to
168 execute the semanage command to sepecify alternate labeling and then
169 use restorecon to put the labels on disk.
170 semanage fcontext -a -t dovecot_deliver_tmp_t '/srv/mydove‐
172 cot_deliver_content(/.*)?'
173 restorecon -R -v /srv/mydovecot_deliver_content
174 Note: SELinux often uses regular expressions to specify labels that
176 match multiple files.
177 The following file types are defined for dovecot_deliver:
179 dovecot_deliver_exec_t
183 - Set files with the dovecot_deliver_exec_t type, if you want to tran‐
185 sition an executable to the dovecot_deliver_t domain.
186 Paths:
189 /usr/libexec/dovecot/deliver, /usr/libexec/dovecot/dovecot-lda
190 dovecot_deliver_tmp_t
193 - Set files with the dovecot_deliver_tmp_t type, if you want to store
195 dovecot deliver temporary files in the /tmp directories.
196 Note: File context can be temporarily modified with the chcon command.
200 If you want to permanently change the file context you need to use the
201 semanage fcontext command. This will modify the SELinux labeling data‐
202 base. You will need to use restorecon to apply the labels.
203
206 semanage fcontext can also be used to manipulate default file context
207 mappings.
208 semanage permissive can also be used to manipulate whether or not a
210 process type is permissive.
211 semanage module can also be used to enable/disable/install/remove pol‐
213 icy modules.
214 semanage boolean can also be used to manipulate the booleans
216 system-config-selinux is a GUI tool available to customize SELinux pol‐
219 icy settings.
