From 364700cf8fd54f54ad08313464105a414e3bccb7 Mon Sep 17 00:00:00 2001 From: Guillaume Nault Date: Thu, 6 Apr 2017 18:31:20 +0200 Subject: [PATCH] l2tp: don't mask errors in pppol2tp_setsockopt() pppol2tp_setsockopt() unconditionally overwrites the error value returned by pppol2tp_tunnel_setsockopt() or pppol2tp_session_setsockopt(), thus hiding errors from userspace.
