This patch adds support for TLS SessionTicket extension (RFC 5077) for
the parts used by EAP-FAST (RFC 4851).
This is based on the patch from Alexey Kobozev <akobozev@cisco.com>
(sent to openssl-dev mailing list on Tue, 07 Jun 2005 15:40:58 +0300).
OpenSSL 0.9.8g does not enable TLS extension support by default, so it
will need to be enabled by adding enable-tlsext to config script
command line.

This patch adds support for TLS SessionTicket extension (RFC 5077) for
the parts used by EAP-FAST (RFC 4851).
This is based on the patch from Alexey Kobozev <akobozev@cisco.com>
(sent to openssl-dev mailing list on Tue, 07 Jun 2005 15:40:58 +0300).
OpenSSL 0.9.8x does not enable TLS extension support by default, so it
will need to be enabled by adding enable-tlsext to config script
command line.

This patch adds support for TLS SessionTicket extension (RFC 5077) for
the parts used by EAP-FAST (RFC 4851).
This is based on the patch from Alexey Kobozev <akobozev@cisco.com>
(sent to openssl-dev mailing list on Tue, 07 Jun 2005 15:40:58 +0300).
NOTE: This patch (without SSL_set_hello_extension() wrapper) was
merged into the upstream OpenSSL 0.9.9 tree and as such, an external
patch for EAP-FAST support is not needed anymore.
