Functions

func GetIcmpNoMatch

func GetIcmpNoMatch() []string

GetIcmpNoMatch returns a rulespec subsection to indicate that there should be no match

func MakeRuleSpecText

func MakeRuleSpecText(winRuleSpec *WindowsRuleSpec, validate bool) (string, error)

MakeRuleSpecText converts a WindowsRuleSpec back into a string for an iptables rule

func ReduceIcmpProtoString

func ReduceIcmpProtoString(icmpProtoTypeCode string, policyRestrictions []string) ([]string, error)

ReduceIcmpProtoString will look at policyRestrictions and return a rulespec substring for matching. represents the logic: "icmpProtoTypeCode and (policyRestrictions[0] or policyRestrictions[1] or...)" can return empty list if there is a proto match with no restriction. will return error if there is no intersection.

func TransformIcmpProtoString

func TransformIcmpProtoString(icmpProtoTypeCode string) []string

TransformIcmpProtoString parses icmp/type/code string coming from ACL rule and returns a rulespec subsection

func WideCharPointerToString

func WideCharPointerToString(pszWide *uint16) string

WideCharPointerToString converts a pointer to a zero-terminated wide character string to a golang string

Types

type WindowsRuleIcmpMatch

type WindowsRuleIcmpMatch struct {
