Functions ¶
func NewDialContext ¶
func NewDialContext(usage string, allowList, blockList *HostMatchList) func(ctx context.Context, network, addr string) (net.Conn, error)
NewDialContext returns a DialContext for Transport, the DialContext will do allow/block list check
Types ¶
type HostMatchList ¶
type HostMatchList struct {
SettingKeyHint string
SettingValue string
// contains filtered or unexported fields
}
HostMatchList is used to check if a host or IP is in a list.
func ParseHostMatchList ¶
func ParseHostMatchList(settingKeyHint, hostList string) *HostMatchList
ParseHostMatchList parses the host list HostMatchList
func ParseSimpleMatchList ¶
func ParseSimpleMatchList(settingKeyHint, matchList string) *HostMatchList
ParseSimpleMatchList parse a simple matchlist (no built-in networks, no CIDR support, only wildcard pattern match)
func (*HostMatchList) AppendBuiltin ¶
func (hl *HostMatchList) AppendBuiltin(builtin string)
AppendBuiltin appends more builtins to match
func (*HostMatchList) AppendPattern ¶
func (hl *HostMatchList) AppendPattern(pattern string)
AppendPattern appends more pattern to match
func (*HostMatchList) IsEmpty ¶
func (hl *HostMatchList) IsEmpty() bool
IsEmpty checks if the checklist is empty
func (*HostMatchList) MatchHostName ¶
func (hl *HostMatchList) MatchHostName(host string) bool
MatchHostName checks if the host matches an allow/deny(block) list
func (*HostMatchList) MatchHostOrIP ¶
func (hl *HostMatchList) MatchHostOrIP(host string, ip net.IP) bool
MatchHostOrIP checks if the host or IP matches an allow/deny(block) list
func (*HostMatchList) MatchIPAddr ¶
func (hl *HostMatchList) MatchIPAddr(ip net.IP) bool
MatchIPAddr checks if the IP matches an allow/deny(block) list, it's safe to pass `nil` to `ip`
