Types ¶
type Dnstap ¶
type Dnstap struct {
// contains filtered or unexported fields
}
Dnstap middleware for binary DNS logging.
func (*Dnstap) ClientOnly ¶ added in v1.6.4
(*Dnstap).ClientOnly marks dnstap as a client-traffic observer; middleware.Setup excludes it from internal sub-pipelines so dnstap streams reflect real client queries only.
func (*Dnstap) ServeDNS ¶
func (d *Dnstap) ServeDNS(ctx context.Context, ch *middleware.Chain)
(*Dnstap).ServeDNS serveDNS logs DNS messages in dnstap format. Disconnected dnstap is a read-lock check and a wire-born request passes undecoded. A connected tap stays on the byte path too: a dnstap frame carries wire bytes, and a wire-born request already is wire bytes — an owned copy taps it without decoding, so the cache's wire ladder (and the inline fast path behind it) keeps working with the tap on. Only a request that arrived decoded (DoH, internal entries) packs.
type DnstapMessage ¶
type DnstapMessage struct {
Type MessageType
Identity []byte
Version []byte
QueryAddress net.IP
QueryPort uint16
Protocol string
QueryTime time.Time
QueryMessage []byte
ResponseTime time.Time
ResponseMsg []byte
}
DnstapMessage represents a simplified dnstap message.
type MessageType ¶
type MessageType uint32
MessageType represents dnstap message types.
const ( MessageTypeQuery MessageType = 1 MessageTypeResponse MessageType = 2 )
