From d5a27006e03174aa518f6c849d377a130a7c705c Mon Sep 17 00:00:00 2001 From: Sergey Kandaurov Date: Tue, 17 Jul 2018 12:53:23 +0300 Subject: SSL: save sessions for upstream peers using a callback function. In TLSv1.3, NewSessionTicket messages arrive after the handshake and can come at any time. Therefore we use a callback to save the session when we know about it. This approach works for < TLSv1.3 as well. The callback function is set once per location on merge phase. Since SSL_get_session() in BoringSSL returns an unresumable session for TLSv1.3, peer save_session() methods have been updated as well to use a session supplied within the callback. To preserve API, the session is cached in c->ssl->session. It is preferably accessed in save_session() methods by ngx_ssl_get_session() and ngx_ssl_get0_session() wrappers. --- src/http/ngx_http_upstream_round_robin.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/http/ngx_http_upstream_round_robin.c') diff --git a/src/http/ngx_http_upstream_round_robin.c b/src/http/ngx_http_upstream_round_robin.c index f6051ae57..f72de3ee6 100644 --- a/src/http/ngx_http_upstream_round_robin.c +++ b/src/http/ngx_http_upstream_round_robin.c @@ -744,7 +744,7 @@ ngx_http_upstream_save_round_robin_peer_session(ngx_peer_connection_t *pc, if (peers->shpool) { - ssl_session = SSL_get0_session(pc->connection->ssl->connection); + ssl_session = ngx_ssl_get0_session(pc->connection); if (ssl_session == NULL) { return; -- cgit
