VMOD_PROXY(3) VMOD_PROXY(3)

vmod_proxy - Varnish Module to extract TLV attributes from PROXYv2

import proxy [from "path"] ;
STRING alpn()
STRING authority()
BOOL is_ssl()
BOOL client_has_cert_sess()
BOOL client_has_cert_conn()
INT ssl_verify_result()
STRING ssl_version()
STRING client_cert_cn()
STRING ssl_cipher()
STRING cert_sign()
STRING cert_key()


vmod_proxy contains functions to extract proxy-protocol-v2 TLV attributes as described in https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt.

Description
Extract alpn attribute.
Example
set req.http.alpn = proxy.alpn();

Description
Extract authority attribute. This corresponds to sni from a tls connection.
Example
set req.http.authority = proxy.authority();

Description
Report if proxy-protocol-v2 has ssl tlv.
Example
if (proxy.is_ssl()) {

set req.http.ssl-version = proxy.ssl_version();
}

Description
Report if the client provided a certificate at least once over the TLS session this connection belongs to.

Description
Report if the client provided a certificate over the current connection.

Description
Report the SSL_get_verify_result from a TLS session. It only matters if client_has_cert_sess() is true. Per default, value is set to 0 (X509_V_OK).
Example
if (proxy.client_has_cert_sess() && proxy.ssl_verify_result() == 0) {

set req.http.ssl-verify = "ok";
}

Description
Extract ssl version attribute.
Example
set req.http.ssl-version = proxy.ssl_version();

Description
Extract the common name attribute of the client certificate's.
Example
set req.http.cert-cn = proxy.client_cert_cn();

Description
Extract the ssl cipher attribute.
Example
set req.http.ssl-cipher = proxy.ssl_cipher();

Description
Extract the certificate signature algorithm attribute.
Example
set req.http.cert-sign = proxy.cert_sign();

Description
Extract the certificate key algorithm attribute.
Example
set req.http.cert-key = proxy.cert_key();
