+Subject: [PATCH] Fix redsocks_evbuffer_readline with libevent 2.1
+
+_EVENT_NUMERIC_VERSION was renamed to EVENT__NUMERIC_VERSION in libevent
+2.1. As a result, redsocks_evbuffer_readline would end up using
+evbuffer_readline(buf), which causes client connections to hang
+indefinitely.
+
+Switch the check to using LIBEVENT_VERSION_NUMBER instead.
+LIBEVENT_VERSION_NUMBER has been around since libevent 2.0.3 and
+redsocks is already using it in other parts of the code.
+
+Upstream-Status: Pending
