From 8efc0ab50edbac5c65191b8a58dfdab3741b7901 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 6 Jan 2006 00:11:44 -0800 Subject: [PATCH] frv: fix signal handling The attached patch makes FRV signal handling work properly: (1) After do_notify_resume() has been called, the work flags must be checked again (there may be another signal to deliver or the process might require rescheduling for instance). (2) After the signal frame is set up on the userspace stack, ptrace() should be given an opportunity to single-step into the signal handler. (3) The error state from setting up a signal frame should be passed back up the call chain. (4) The segfault handler shouldn't be preemptively reset in the arch if we fail to deliver a SEGV signal: force_sig() will take care of that.
