Types ¶
type ManagedSet ¶
type ManagedSet struct {
WaitGroup *sync.WaitGroup
Conn *nftables.Conn
Set *Set
// contains filtered or unexported fields
}
Represents a set managed by the manager goroutine
func ManagerInit ¶ added in v0.0.2
func ManagerInit(wg *sync.WaitGroup, c *nftables.Conn, set *Set, f SetUpdateFunc, interval time.Duration, logger logger.Logger) (ManagedSet, error)
Create a set manager
type Set ¶
Set represents an nftables a set on a given table
func New ¶
func New(name string, c *nftables.Conn, table *nftables.Table, keyType nftables.SetDatatype) (Set, error)
Create a new set on a table with a given key type
func (*Set) ClearAndAddElements ¶
Remove all elements from the set and then add a list of elements
type SetData ¶
type SetData struct {
Port int
PortRangeStart int
PortRangeEnd int
Address netip.Addr
AddressRangeStart netip.Addr
AddressRangeEnd netip.Addr
Prefix netip.Prefix
}
SetData is a struct that is used to create elements of a given set based on the key type of the set
func AddressRangeStringToSetData ¶
Convert a string address range to the SetData type
func AddressStringToSetData ¶
Convert a string address to the SetData type
func AddressStringsToSetData ¶
Convert a list of string addresses to the SetData type
func IPNetToSetData ¶
Convert net.IPNet to the SetData type
func IPNetsToSetData ¶
Convert a list of net.IPNet to the SetData type
func IPsToSetData ¶
Convert a list of net.IP to the SetData type
func PortRangeStringToSetData ¶
Convert a string port range to the SetData type
func PortStringToSetData ¶
Convert a string port to the SetData type
func PortStringsToSetData ¶
Convert a list string ports to the SetData type
func PrefixStringToSetData ¶
Convert a string prefix/CIDR to the SetData type
