Overview

Package iface provides access to network connection operations via file descriptor. The implementation MUST be correct by inspection.

Types

type ConnFile

type ConnFile interface {
	DupFile(tc *net.TCPConn) (*os.File, error)
}

ConnFile provides access to underlying network file.

type NetInfo

type NetInfo interface {
	GetUUID(fp *os.File) (string, error)
	GetBBRInfo(fp *os.File) (inetdiag.BBRInfo, error)
	GetTCPInfo(fp *os.File) (*tcp.LinuxTCPInfo, error)
}

NetInfo provides access to network connection metadata.

type RealConnInfo

type RealConnInfo struct{}

RealConnInfo implements both the ConnFile and NetInfo interfaces.

func (*RealConnInfo) DupFile

func (f *RealConnInfo) DupFile(tc *net.TCPConn) (*os.File, error)

DupFile returns the corresponding *os.File. Note that the returned *os.File is a dup() of the original, hence you now have ownership of two objects that you need to remember to defer Close() of.

func (*RealConnInfo) GetBBRInfo

func (f *RealConnInfo) GetBBRInfo(fp *os.File) (inetdiag.BBRInfo, error)

GetBBRInfo returns BBRInfo for the given file pointer.

func (*RealConnInfo) GetTCPInfo

func (f *RealConnInfo) GetTCPInfo(fp *os.File) (*tcp.LinuxTCPInfo, error)

GetTCPInfo returns TCPInfo for the given file pointer.

func (*RealConnInfo) GetUUID

func (f *RealConnInfo) GetUUID(fp *os.File) (string, error)

GetUUID returns a UUID for the given file pointer.
