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 all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62 setsebool -P allow_domain_fd_use 1
64 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69 setsebool -P allow_kerberos 1
71 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76 setsebool -P allow_ptrace 1
78 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83 setsebool -P allow_ypbind 1
85 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91 setsebool -P domain_kernel_load_modules 1
93 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98 setsebool -P fips_mode 1
100 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105 setsebool -P global_ssp 1
107 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.
112 setsebool -P nscd_use_shm 1
114 If you want to support NFS home directories, you must turn on the
118 use_nfs_home_dirs boolean. Disabled by default.
119 setsebool -P use_nfs_home_dirs 1
121 If you want to support SAMBA home directories, you must turn on the
125 use_samba_home_dirs boolean. Disabled by default.
126 setsebool -P use_samba_home_dirs 1

132 The SELinux process type dovecot_deliver_t can manage files labeled
133 with the following file types. The paths listed are the default paths
134 for these file types. Note the processes UID still need to have DAC
135 permissions.
136 cifs_t
138 dovecot_deliver_tmp_t
141 dovecot_spool_t
144 /var/spool/dovecot(/.*)?

195 SELinux requires files to have an extended attribute to define the file
196 type.
197 You can see the context of a file using the -Z option to ls
199 Policy governs the access confined processes have to these files.
201 SELinux dovecot_deliver policy is very flexible allowing users to setup
202 their dovecot_deliver processes in as secure a method as possible.
203 STANDARD FILE CONTEXT
205 SELinux defines the file context types for the dovecot_deliver, if you
207 wanted to store files with these types in a diffent paths, you need to
208 execute the semanage command to sepecify alternate labeling and then
209 use restorecon to put the labels on disk.
210 semanage fcontext -a -t dovecot_deliver_tmp_t '/srv/mydove‐
212 cot_deliver_content(/.*)?'
213 restorecon -R -v /srv/mydovecot_deliver_content
214 Note: SELinux often uses regular expressions to specify labels that
216 match multiple files.
217 The following file types are defined for dovecot_deliver:
219 dovecot_deliver_exec_t
223 - Set files with the dovecot_deliver_exec_t type, if you want to tran‐
225 sition an executable to the dovecot_deliver_t domain.
226 Paths:
229 /usr/libexec/dovecot/deliver, /usr/libexec/dovecot/dovecot-lda
230 dovecot_deliver_tmp_t
233 - Set files with the dovecot_deliver_tmp_t type, if you want to store
235 dovecot deliver temporary files in the /tmp directories.
236 Note: File context can be temporarily modified with the chcon command.
240 If you want to permanently change the file context you need to use the
241 semanage fcontext command. This will modify the SELinux labeling data‐
242 base. You will need to use restorecon to apply the labels.
243
246 semanage fcontext can also be used to manipulate default file context
247 mappings.
248 semanage permissive can also be used to manipulate whether or not a
250 process type is permissive.
251 semanage module can also be used to enable/disable/install/remove pol‐
253 icy modules.
254 semanage boolean can also be used to manipulate the booleans
256 system-config-selinux is a GUI tool available to customize SELinux pol‐
259 icy settings.
