NAME dovecot_deliver_selinux - Security Enhanced Linux Policy for the dove- cot_deliver processes

DESCRIPTION Security-Enhanced Linux secures the dovecot_deliver processes via flex- ible mandatory access control.

The dovecot_deliver processes execute with the dovecot_deliver_t SELinux type. You can check if you have these processes running by exe- cuting the ps command with the -Z qualifier.

For example:

ps -eZ | grep dovecot_deliver_t

ENTRYPOINTS The dovecot_deliver_t SELinux type can be entered via the "dove- cot_deliver_exec_t" file type. The default entrypoint paths for the dovecot_deliver_t domain are the following:"

/usr/libexec/dovecot/deliver, /usr/libexec/dovecot/dovecot-lda

PROCESS TYPES SELinux defines process types (domains) for each process running on the system

You can see the context of a process using the -Z option to ps

Policy governs the access confined processes have to files. SELinux dovecot_deliver policy is very flexible allowing users to setup their dovecot_deliver processes in as secure a method as possible.

The following process types are defined for dovecot_deliver:

dovecot_deliver_t

Note: semanage permissive -a dovecot_deliver_t

can be used to make the process type dovecot_deliver_t permissive. Per- missive process types are not denied access by SELinux. AVC messages will still be generated.

FILE CONTEXTS SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to ls

Policy governs the access confined processes have to these files. SELinux dovecot_deliver policy is very flexible allowing users to setup their dovecot_deliver processes in as secure a method as possible.

The following file types are defined for dovecot_deliver:

dovecot_deliver_exec_t

- Set files with the dovecot_deliver_exec_t type, if you want to tran- sition an executable to the dovecot_deliver_t domain.

dovecot_deliver_tmp_t

- Set files with the dovecot_deliver_tmp_t type, if you want to store dovecot deliver temporary files in the /tmp directories.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.

MANAGED FILES The SELinux process type dovecot_deliver_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

dovecot_deliver_tmp_t

dovecot_spool_t

/var/spool/dovecot(/.*)?

COMMANDS semanage fcontext can also be used to manipulate default file context mappings.

semanage permissive can also be used to manipulate whether or not a process type is permissive.

semanage module can also be used to enable/disable/install/remove pol- icy modules.

system-config-selinux is a GUI tool available to customize SELinux pol- icy settings.
