Functions ¶

func Contain ¶ added in v1.4.0

func Contain(keys []netlink.TcU32Key, subKeys []netlink.TcU32Key) bool

func FilterBySrcIP ¶ added in v1.3.0

func FilterBySrcIP(link netlink.Link, parent uint32, ipNet *net.IPNet) (*netlink.U32, error)

FilterBySrcIP found u32 filter by pod ip used for prio only.

Note: match keys are family-specific (IPv4 → 1 key at off=12; IPv6 → 4 keys at off=8/12/16/20), so the key set alone disambiguates address family. We intentionally do not compare u32.Protocol here so this lookup tolerates existing filters created with either ETH_P_IP or ETH_P_IPV6 (older builds always used ETH_P_IP for both families).

func MatchSrc ¶ added in v1.3.0

func MatchSrc(u32 *netlink.U32, ipNet *net.IPNet)

MatchSrc add match for source ip

func SetRule ¶

func SetRule(dev netlink.Link, rule *TrafficShapingRule) error

SetRule set the traffic rule on interface

func U32IPv4Src ¶ added in v1.3.0

func U32IPv4Src(ipNet *net.IPNet) netlink.TcU32Key

func U32IPv6Src ¶ added in v1.3.0

func U32IPv6Src(ipNet *net.IPNet) []netlink.TcU32Key

func U32MatchSrc ¶ added in v1.3.0

func U32MatchSrc(ipNet *net.IPNet) []netlink.TcU32Key

U32MatchSrc return u32 match key by src ip

Types ¶

type TrafficShapingRule ¶ added in v1.1.0

type TrafficShapingRule struct {
	// rate in bytes
	Rate uint64
}

TrafficShapingRule the interface traffic shaping rule
