+# Fix possible hang on closed output.
+#
+# When there is a connectivity problem between the server and the client
+# (network outage, server crash or reboot), the client indefinitely hangs.
+#
+# This patch fixes the issue by checking ssh_packet_write_poll return value
+# in ssh_packet_write_wait and passing it through.
+#
+# The (updated) patch has been accepted upstream and will be part of 7.2
+# https://github.com/openssh/openssh-portable/commit/8408218
