X-Git-Tag: OpenSSL_1_1_0-pre1~1655
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f2baac27d5f95326fa441e1cb08925b46f88b21c;p=oweals%2Fopenssl.git

Provide the API functions SSL_SESSION_has_ticket and
SSL_SESSION_get_ticket_lifetime_hint. The latter has been reported as
required to fix Qt for OpenSSL 1.1.0. I have also added the former in order
to determine whether a ticket is present or not - otherwise it is difficult
to know whether a zero lifetime hint is because the server set it to 0, or
because there is no ticket.
