Types ¶
type Entity ¶
type Entity struct {
sync.Mutex
// IP is the IP address of the connection. If domain is
// set, IP has been resolved by following all CNAMEs.
IP net.IP
// IPScope holds the network scope of the IP.
// For DNS requests, this signifies in which scope the DNS request was resolved.
IPScope netutils.IPScope
// Protocol is the protcol number used by the connection.
Protocol uint8
// Port is the remote port of the connection
Port uint16
// Domain is the target domain of the connection.
Domain string
// ReverseDomain is the domain the IP address points to. This is only
// resolved and populated when needed.
ReverseDomain string
// CNAME is a list of domain names that have been
// resolved for Domain.
CNAME []string
// Country holds the country the IP address (ASN) is
// located in.
Country string
// Coordinates holds the approximate coordinates of the IP address.
Coordinates *geoip.Coordinates
// ASN holds the autonomous system number of the IP.
ASN uint
// ASOrg holds the owner's name of the autonomous system.
ASOrg string
// LocationError holds an error message if fetching the location failed.
LocationError string
// BlockedByLists holds list source IDs that
// are used to block the entity.
BlockedByLists []string
// BlockedEntities holds a list of entities that
// have been blocked. Values can be used as a key
// for the ListOccurences map.
BlockedEntities []string
// ListOccurences is a map that matches an entity (Domain, IPs, ASN, Country, Sub-domain)
// to a list of sources where the entity has been observed in.
ListOccurences map[string][]string
// ListsError holds an error message if fetching the lists failed.
ListsError string
// contains filtered or unexported fields
}
Entity describes a remote endpoint in many different ways. It embeddes a sync.Mutex but none of the endpoints own functions performs locking. The caller MUST ENSURE proper locking and synchronization when accessing any properties of Entity.
func (*Entity) CNAMECheckEnabled ¶
CNAMECheckEnabled returns true if the entities CNAMEs should also be checked.
func (*Entity) EnableCNAMECheck ¶
EnableCNAMECheck enalbes or disables list lookups for entity CNAMEs.
func (*Entity) EnableReverseResolving ¶
func (e *Entity) EnableReverseResolving()
EnableReverseResolving enables reverse resolving the domain from the IP on demand.
func (*Entity) FetchData ¶
FetchData fetches additional information, meant to be called before persisting an entity record.
func (*Entity) GetCountry ¶
GetCountry returns the two letter ISO country code and whether it is set.
func (*Entity) GetCountryInfo ¶
func (e *Entity) GetCountryInfo(ctx context.Context) *geoip.CountryInfo
GetCountryInfo returns the two letter ISO country code and whether it is set.
func (*Entity) GetLocation ¶
GetLocation returns the raw location data and whether it is set.
func (*Entity) Init ¶
Init initializes internal metadata about the entity. If the entity does not describe a destination, you can supply a different destination port for endpoint matching. It returns the entity itself for single line formatting.
func (*Entity) ListBlockReason ¶
func (e *Entity) ListBlockReason() ListBlockReason
ListBlockReason returns the block reason for this entity.
func (*Entity) MatchLists ¶
MatchLists matches the entities lists against a slice of source IDs and updates various entity properties like BlockedByLists, ListOccurences and BlockedEntitites.
func (*Entity) ResetLists ¶
func (e *Entity) ResetLists()
ResetLists resets the current list data and forces all list sources to be re-acquired when calling GetLists().
type ListBlockReason ¶
type ListBlockReason []ListMatch
ListBlockReason is a list of list matches.
func (ListBlockReason) Context ¶
func (br ListBlockReason) Context() interface{}
Context returns br wrapped into a map. It implements the endpoints.Reason interface.
func (ListBlockReason) GetExtraRRs ¶
GetExtraRRs implements the nsutil.RRProvider interface and adds additional TXT records justifying the reason the request was blocked.
func (ListBlockReason) MarshalJSON ¶
func (br ListBlockReason) MarshalJSON() ([]byte, error)
MarshalJSON marshals the list block reason into a map prefixed with filterlists.
func (ListBlockReason) String ¶
func (br ListBlockReason) String() string
