From 7a36967029c0dc062bdc25fc28fb2c1d0bbca179 Mon Sep 17 00:00:00 2001 From: Tiwei Bie Date: Tue, 6 Mar 2018 18:43:25 +0800 Subject: [PATCH] vhost: do not generate signal when sendmsg fails More precisely, do not generate a SIGPIPE signal if the peer has closed the connection. Otherwise, it will terminate the process by default. As a library, we should avoid terminating the application process when error happens and just need to return with an error.
