该问题是由于 环境上istiod所下发xds配置无法正确解析,导致kmesh解析出来的字段中部分ip段为空,在go控制面
/usr/lib/golang/src/encoding/binary/binary.go:80中进行IP的大小端转换的时候对内存进行检查发现IP为空,导致panic

func (littleEndian) Uint32(b []byte) uint32 {
_ = b[3] // bounds check hint to compiler; see golang.org/issue/14808
return uint32(b[0]) | uint32(b[1])<<8 | uint32(b[2])<<16 | uint32(b[3])<<24
}

可能是kmesh的七层对istio 1.19版本的支持还不够完善,在较低版本(istio<=1.18.3 k8s <=1.20)支持良好,后续会测试并完善更多版本支持

好的,确实是istio版本的问题,我降到1.14.5就可以了。
