From aef553fdcabbea8760cd4647ab14859095300023 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 16 May 2014 14:00:03 +0100 Subject: iohandler.c: Properly initialize sigaction struct The code in qemu_init_child_watch() wasn't clearing the 'struct sigaction' before passing it to sigaction(); this meant that we would block a random set of signals while executing the SIGCHLD handler. Initialize properly by using memset() on the struct, as we do in similar cases elsewhere.
