From 819121b9b08a41ccfcde2e18eb782f8f6b2912f1 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 13 Aug 2021 14:18:06 +0100 Subject: linux-user: Zero out target_siginfo_t in force_sig() The target_siginfo_t we populate in force_sig() will eventually get copied onto the target's stack. Zero it out so that any extra padding in the sifields union is consistently zero when the guest sees it.
