Allow IRC control characters to appear even if protocol encoding explicitly disallows them.

◆ PutIRC() [1/2]

void CIRCSock::PutIRC ( const CMessage & Message )

Sends a message to the server.

Parameters

Message The message to be sent.

Note: Only known and compatible messages and tags are sent.

This method can delay the delivery of the message to honor protection from flood.

This method ensures that only tags, that were negotiated with CAP REQ and CAP ACK, are sent. Not all IRC server are capable of handling all messages and tags. Thus, in order to stay compatible with a variety of IRC servers, ZNC has to filter out messages and tags that the server has not explicitly acknowleged.

Additional tags can be added via \l CIRCSock::SetTagSupport().

Warning: Bypassing the filter may cause troubles to some older IRC servers.

It is possible to bypass the filter by converting a message to a string using \l CMessage::ToString(), and passing the resulting raw line to the \l CIRCSock::PutIRCRaw(const CString& sLine):

pServer->PutIRCRaw(Message.ToString());

◆ PutIRC() [2/2]

Parameters

sLine The line to be sent.

The line is first passed unmodified to the CModule::OnSendToIRC() module hook. If no module halts the process, the line is then sent to the server.

Prefer \l PutIRC() instead.

◆ Quit()

virtual bool Csock::SNIConfigureClient ( CS_STRING & sHostname )

virtualinherited

called to configure the SNI client

Parameters

sHostname,the hostname to configure SNI with, you can fill this with GetHostname() if its a valid hostname and not an OP

Returns: returning true causes a call to configure SNI with the hostname returned

◆ SNIConfigureClient() [2/2]

bool CZNCSock::SNIConfigureClient ( CString & sHostname )

overrideinherited

◆ SNIConfigureServer()

virtual bool Csock::SNIConfigureServer	(	const CS_STRING &	sHostname,
		CS_STRING &	sPemFile,
		CS_STRING &	sPemPass
	)

inlinevirtualinherited

gets called when a SNI request is sent, and used to configure a SNI session

Parameters

sHostname	the hostname sent from the client
sPemFile	fill this with the location to the pemfile
sPemPass	fill this with the pemfile password if there is one

Returns: return true to proceed with the SNI server configuration

◆ SockError() [1/2]

virtual void Csock::SockError	(	int	iErrno,
		const CS_STRING &	sDescription
	)

inlinevirtualinherited

A sock error occured event.

◆ SockError() [2/2]

void CIRCSock::SockError	(	int	iErrno,

◆ SSLCertError()

void CIRCSock::SSLCertError ( X509 * pCert )

overridevirtual

Reimplemented from CZNCSock.

◆ SSLClientSetup()

virtual bool Csock::SSLClientSetup ( )

virtualinherited

This sets up the SSL Client, this is used internally.

◆ SSLFinishSetup()

virtual void Csock::SSLFinishSetup ( SSL * pSSL )

inlinevirtualinherited

Gets called immediatly after the m_ssl member is setup and initialized, useful if you need to assign anything to this ssl session via SSL_set_ex_data.

◆ SSLHandShakeFinished()

void CZNCSock::SSLHandShakeFinished ( )

overridevirtualinherited

called once the SSL handshake is complete, this is triggered via SSL_CB_HANDSHAKE_DONE in SSL_set_info_callback()

This is a spot where you can look at the finished peer certifificate ... IE

X509 * pCert = GetX509();
char szName[256];
memset( szName, '\0', 256 );
X509_NAME_get_text_by_NID ( X509_get_subject_name( pCert ), NID_commonName, szName, 255 );
cerr << "Name! " << szName << endl;
X509_free( pCert );

Reimplemented from Csock.

◆ SslIsEstablished()

bool Csock::SslIsEstablished ( ) const

inherited

is SSL_accept finished ? is the ssl properly finished (from write no error)

◆ SSLServerSetup()

virtual bool Csock::SSLServerSetup ( )

virtualinherited

This sets up the SSL Server, this is used internally.

◆ StartTLS()

bool Csock::StartTLS ( )

inherited

start a TLS connection on an existing plain connection

◆ Timeout()

void CIRCSock::Timeout ( )

overridevirtual

Sock Timed out event.

Reimplemented from Csock.

◆ UnPauseRead()

void Csock::UnPauseRead ( )

inherited

◆ VerifyPeerCertificate()

int CZNCSock::VerifyPeerCertificate	(	int	iPreVerify,
		X509_STORE_CTX *	pStoreCTX
	)

overridevirtualinherited

this is hooked in via SSL_set_verify, and be default it just returns 1 meaning success

Parameters

iPreVerify	the pre-verification status as determined by openssl internally
pStoreCTX	the X509_STORE_CTX containing the certificate

Returns: 1 to continue, 0 to abort

This may get called multiple times, for example with a chain certificate which is fairly typical with certificates from godaddy, freessl, etc. Additionally, openssl does not do any host verification, they leave that up to the you. One easy way to deal with this is to wait for SSLHandShakeFinished() and examine the peer certificate

Reimplemented from Csock.

◆ Write() [1/2]

virtual bool Csock::Write	(	const char *	data,
		size_t	len
	)

virtualinherited

Write data to the socket.

If not all of the data is sent, it will be stored on an internal buffer, and tried again with next call to Write if the socket is blocking, it will send everything, its ok to check ernno after this (nothing else is processed)

Parameters

data	the data to send
len	the length of data

◆ Write() [2/2]

virtual bool Csock::Write ( const CS_STRING & sData )

virtualinherited

Write a text string to the socket.

Encoding is used, if set

Parameters

sData the string to send; if encoding is provided, sData should be UTF-8 and will be encoded

See also: Write( const char *, int )
