From aad87b88fc2536b1ea023213729aaf4eaabe1894 Mon Sep 17 00:00:00 2001
From: "djm@openbsd.org" <djm@openbsd.org>

Subject: [PATCH] upstream: when receving a file in sink(), be careful to send
at
most a single error response after the file has been opened. Otherwise the
source() and sink() can become desyncronised. Reported by Daniel Goujot,
Georges-Axel Jaloyan, Ryan Lahfa, and David Naccache.
