func IsClosedConnError ¶
func IsClosedConnError(err error) bool
IsClosedConnError returns true if the error is from closing listener, cmux. copied from golang.org/x/net/http2/http2.go
func LimitListener ¶
func LimitListener(l net.Listener, n int) net.Listener
LimitListener returns a Listener that accepts at most n simultaneous connections from the provided Listener.
func NewKeepAliveListener ¶
func NewKeepAliveListener(l net.Listener, scheme string, tlscfg *tls.Config) (net.Listener, error)
NewKeepAliveListener returns a listener that listens on the given address. Be careful when wrap around KeepAliveListener with another Listener if TLSInfo is not nil. Some pkgs (like go/http) might expect Listener to return TLSConn type to start TLS handshake. http://tldp.org/HOWTO/TCP-Keepalive-HOWTO/overview.html
func NewListener ¶
func NewListener(addr, scheme string, tlsinfo *TLSInfo) (l net.Listener, err error)
func NewTimeoutListener ¶
func NewTimeoutListener(addr string, scheme string, tlsinfo *TLSInfo, rdtimeoutd, wtimeoutd time.Duration) (net.Listener, error)
NewTimeoutListener returns a listener that listens on the given address. If read/write on the accepted connection blocks longer than its time limit, it will return timeout error.
func NewTimeoutTransport ¶
func NewTimeoutTransport(info TLSInfo, dialtimeoutd, rdtimeoutd, wtimeoutd time.Duration) (*http.Transport, error)
NewTimeoutTransport returns a transport created using the given TLS info. If read/write on the created connection blocks longer than its time limit, it will return timeout error. If read/write timeout is set, transport will not be able to reuse connection.
func NewTransport ¶
func NewTransport(info TLSInfo, dialtimeoutd time.Duration) (*http.Transport, error)
func NewUnixListener ¶
func NewUnixListener(addr string) (net.Listener, error)
func ValidateSecureEndpoints ¶
func ValidateSecureEndpoints(tlsInfo TLSInfo, eps []string) ([]string, error)
ValidateSecureEndpoints scans the given endpoints against tls info, returning only those endpoints that could be validated as secure.
type TLSInfo ¶
type TLSInfo struct {
CertFile string
KeyFile string
CAFile string
TrustedCAFile string
ClientCertAuth bool
// ServerName ensures the cert matches the given host in case of discovery / virtual hosting
ServerName string
// HandshakeFailure is optionally called when a connection fails to handshake. The
// connection will be closed immediately afterwards.
HandshakeFailure func(*tls.Conn, error)
// contains filtered or unexported fields
}
func SelfCert ¶
func SelfCert(dirpath string, hosts []string) (info TLSInfo, err error)
func (TLSInfo) ClientConfig ¶
func (info TLSInfo) ClientConfig() (*tls.Config, error)
ClientConfig generates a tls.Config object for use by an HTTP client.
func (TLSInfo) Empty ¶
func (info TLSInfo) Empty() bool
func (TLSInfo) ServerConfig ¶
func (info TLSInfo) ServerConfig() (*tls.Config, error)
ServerConfig generates a tls.Config object for use by an HTTP server.
func (TLSInfo) String ¶
func (info TLSInfo) String() string
