Module filter

Framework for packet filtering.

Structs

• AddressMatcher
  A matcher for IP addresses.
• FilterApi
  The filtering API.
• Hook
  A particular entry point for packet processing in which filtering routines are installed.
• IpRoutines
  Routines that perform ordinary IP filtering.
• NatRoutines
  Routines that can perform NAT.
• PacketMatcher
  Top-level matcher for IP packets.
• PortMatcher
  A matcher for transport-layer port numbers.
• ProofOfEgressCheck
  A witness type to indicate that the egress filtering hook has been run.
• Routine
  A sequence of Rules.
• Routines
  IP version-specific filtering routine state.
• Rule
  A set of criteria (matchers) and a resultant action to take if a given packet matches.
• TransportProtocolMatcher
  A matcher for transport-layer protocol or port numbers.
• Tuple
  A tuple for a flow in a single direction.
• UninstalledRoutine
  A handle to a Routine that is not installed in a particular hook, and therefore is only run if jumped to from another routine.

Enums

• Action
  The action to take on a packet.
• AddressMatcherType
  A matcher for IP addresses.
• InterfaceMatcher
  A matcher for network interfaces.
• TransparentProxy
  Transparently intercept the packet and deliver it to a local socket without changing the packet header.
• ValidationError
  Provided filtering state was invalid.

Traits

• FilterBindingsContext
  Trait aggregating functionality required from bindings.
• FilterBindingsTypes
  Trait defining required types for filtering provided by bindings.
• InterfaceProperties
  Allows filtering code to match on properties of an interface (ID, name, and device class) without Netstack3 Core (or Bindings, in the case of the device class) having to specifically expose that state.
