From 3c6abbe85bccd8efb5d9147a022b1d4012cb1809 Mon Sep 17 00:00:00 2001 From: Stefano Garzarella Date: Wed, 14 May 2025 16:19:27 +0200 Subject: [PATCH] vsock/test: check also expected errno on sigpipe test In the sigpipe test, we expect send() to fail, but we do not check if send() fails with the errno we expect (EPIPE). Add this check and repeat the send() in case of EINTR as we do in other tests.
