From 970688e64df97de6756b57063b7167878a25b404 Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Fri, 28 Mar 2025 15:27:18 +0100 Subject: [PATCH] selftests: mptcp: close fd_in before returning in main_loop commit c183165f87a486d5879f782c05a23c179c3794ab upstream. The file descriptor 'fd_in' is opened when cfg_input is configured, but not closed in main_loop(), this patch fixes it.
