Detailed Description

TLS layer for socket connection.

Member Enumeration Documentation

TlsHSRevert

enum XrdCl::Tls::TlsHSRevert

private

Flags to indicate what is the TLS hand-shake revert state

• None : there is no revert state
• ReadOnWrite : OnRead routines will be called on write event due to TLS handshake
• WriteOnRead : OnWrite routines will be called on read event due to TLS handshake

Enumerator
None
ReadOnWrite
WriteOnRead

Constructor & Destructor Documentation

Tls()

XrdCl::Tls::Tls	(	Socket *	socket,
		AsyncSocketHandler *	socketHandler
	)

Constructor - creates async TLS layer for given socker file descriptor.

~Tls()

XrdCl::Tls::~Tls ( )

inline

Destructor.

Member Function Documentation

ClearErrorQueue()

static void XrdCl::Tls::ClearErrorQueue ( )

static

Clear the error queue for the calling thread.

Connect()

XRootDStatus XrdCl::Tls::Connect	(	const std::string &	thehost,
		XrdNetAddrInfo *	netInfo
	)

Establish a TLS/SSL session and perform host verification.

MapEvent()

uint8_t XrdCl::Tls::MapEvent

(

uint8_t

event

)

Map:

• in case the TLS layer requested reads on writes map ReadyToWrite to ReadyToRead
• in case the TLS layer requested writes on reads map ReadyToRead to ReadyToWrite

Read()

XRootDStatus XrdCl::Tls::Read	(	char *	buffer,
		size_t	size,
		int &	bytesRead
	)

Read through the TLS layer from the socket If necessary, will establish a TLS/SSL session.

Send()

XRootDStatus XrdCl::Tls::Send	(	const char *	buffer,
		size_t	size,
		int &	bytesWritten
	)

Write through the TLS layer to the socket If necessary, will establish a TLS/SSL session.

ToStatus()

XRootDStatus XrdCl::Tls::ToStatus ( XrdTls::RC  rc )

private

Translate OPEN SSL error code into XRootD Status.

Member Data Documentation

pSocketHandler

AsyncSocketHandler* XrdCl::Tls::pSocketHandler

private

Socket handler (for enabling/disabling write notification)

pTls

std::unique_ptr<XrdTlsSocket> XrdCl::Tls::pTls

private

The TSL I/O wrapper over socket.

pTlsHSRevert

TlsHSRevert XrdCl::Tls::pTlsHSRevert
