From c54cc234b4732355629baccac945c863c8a8684e Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 25 Apr 2019 22:09:09 +0100 Subject: binfmt_elf: Fix missing SIGKILL for empty PIE Commit ea08dc5191d9 "fs/binfmt_elf.c: fix bug in loading of PIE binaries", which was a backport of commit a87938b2e246 upstream, added a new failure path to load_elf_binary(). Before commit 19d860a140be "handle suicide on late failure exits in execve() in search_binary_handler()", load_elf_binary() wass responsible for sending a fatal signal to the task in case of an error after flushing the old executable. Add that to the new failure path.
