From e921e00d4ba6840063d69cb637331d0dc4905e4b Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 25 Mar 2024 10:41:00 +0000 Subject: [PATCH] tests/unit/socket-helpers: Don't close(-1) In socket_check_afunix_support() we call socket(PF_UNIX, SOCK_STREAM, 0) to see if it works, but we call close() on the result whether it worked or not. Only close the fd if the socket() call succeeded. Spotted by Coverity.
