From a9c1741820830ea47d4ebfbc7a87fac902e764bf Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Sun, 4 Dec 2016 18:42:09 +0100 Subject: [PATCH] MINOR: connection: add a .get_alpn() method to xprt_ops This will be used to retrieve the ALPN negociated over SSL (or possibly via the proxy protocol later). It's likely that this information should be stored in the connection itself, but it requires adding an extra pointer and an extra integer. Thus better rely on the transport layer to pass this info for now. --- include/proto/connection.h | 7 +++++++ include/types/connection.h | 1 + 2 files changed, 8 insertions(+) diff --git a/include/proto/connection.h b/include/proto/connection.h index e8674462b..09467ba50 100644 --- a/include/proto/connection.h +++ b/include/proto/connection.h @@ -650,6 +650,13 @@ static inline struct xprt_ops *xprt_get(int id) return registered_xprt[id]; } +static inline int conn_get_alpn(const struct connection *conn, const char **str, int *len) +{ + if (!conn_xprt_ready(conn) || !conn->xprt->get_alpn) + return 0; + return conn->xprt->get_alpn(conn, str, len); +} + #endif /* _PROTO_CONNECTION_H */ /* diff --git a/include/types/connection.h b/include/types/connection.h index 60d977218..1e3fb7389 100644 --- a/include/types/connection.h +++ b/include/types/connection.h @@ -228,6 +228,7 @@ struct xprt_ops { void (*destroy_bind_conf)(struct bind_conf *conf); /* destroy a whole bind_conf */ int (*prepare_srv)(struct server *srv); /* prepare a server context */ void (*destroy_srv)(struct server *srv); /* destroy a server context */ + int (*get_alpn)(const struct connection *conn, const char **str, int *len); /* get application layer name */ char name[8]; /* transport layer name, zero-terminated */ };
