greylist_selinux(8) greylist SELinux Policy documentation greylist_selinux(8)NAMEgreylist_selinux - Security Enhanced Linux Policy for the greylist pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the greylist processes via flexible
mandatory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the
greylist_milter_t, you must turn on the authlogin_nsswitch_use_ldap
boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
greylist_milter_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the greylist_milter_t,
you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
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 greylist policy is very flexible allowing users to setup their
greylist processes in as secure a method as possible.
The following file types are defined for greylist:
greylist_milter_data_t
- Set files with the greylist_milter_data_t type, if you want to treat
the files as greylist milter content.
Paths:
/var/run/milter-greylist.pid, /var/run/milter-greylist(/.*)?,
/var/lib/milter-greylist(/.*)?
greylist_milter_exec_t
- Set files with the greylist_milter_exec_t type, if you want to tran‐
sition an executable to the greylist_milter_t domain.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
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
greylist policy is very flexible allowing users to setup their greylist
processes in as secure a method as possible.
The following process types are defined for greylist:
greylist_milter_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
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.
