NAME fetchmail_selinux - Security Enhanced Linux Policy for the fetchmail processes

DESCRIPTION Security-Enhanced Linux secures the fetchmail processes via flexible mandatory access control.

The fetchmail processes execute with the fetchmail_t SELinux type. You can check if you have these processes running by executing the ps com- mand with the -Z qualifier.

For example:

ps -eZ | grep fetchmail_t

ENTRYPOINTS The fetchmail_t SELinux type can be entered via the "fetchmail_exec_t" file type. The default entrypoint paths for the fetchmail_t domain are the following:"

/usr/bin/fetchmail

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 fetchmail policy is very flexible allowing users to setup their fetch- mail processes in as secure a method as possible.

The following process types are defined for fetchmail:

fetchmail_t

Note: semanage permissive -a fetchmail_t

can be used to make the process type fetchmail_t permissive. Permissive 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 fetchmail policy is very flexible allowing users to setup their fetchmail processes in as secure a method as possible.

The following file types are defined for fetchmail:

fetchmail_etc_t

- Set files with the fetchmail_etc_t type, if you want to store fetch- mail files in the /etc directories.

fetchmail_exec_t

- Set files with the fetchmail_exec_t type, if you want to transition an executable to the fetchmail_t domain.

fetchmail_uidl_cache_t

- Set files with the fetchmail_uidl_cache_t type, if you want to store the files under the /var/cache directory.

fetchmail_var_run_t

- Set files with the fetchmail_var_run_t type, if you want to store the fetchmail files under the /run directory.

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 fetchmail_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.

fetchmail_uidl_cache_t

/var/mail/.fetchmail-UIDL-cache

fetchmail_var_run_t

/var/run/fetchmail/.*

initrc_tmp_t

mnt_t

/mnt(/[^/]*) /mnt(/[^/]*)? /rhev(/[^/]*)? /media(/[^/]*) /media(/[^/]*)? /etc/rhgb(/.*)? /media/.hal-.* /net /afs /misc /rhev

root_t

/ /initrd

sendmail_log_t

/var/log/mail(/.*)? /var/log/sendmail.st.*

tmp_t

/tmp /usr/tmp /var/tmp /var/tmp/vi.recover

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.
