From 91d44ff860a9e9c0db81a89cbc24fa31fbd8e6d3 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Sun, 18 Aug 2013 13:30:08 +0200 Subject: um: Cleanup SIGTERM handling Richard reported that some UML processes survive if the UML main process receives a SIGTERM. This issue was caused by a wrongly placed signal(SIGTERM, SIG_DFL) in init_new_thread_signals(). It disabled the UML exit handler accidently for some processes. The correct solution is to disable the fatal handler for all UML helper threads/processes. Such that last_ditch_exit() does not get called multiple times and all processes can exit due to SIGTERM.
