From fef47e2a2e1e75fe50a10f634a80f16808348cc6 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Mon, 5 May 2014 18:07:12 +0200 Subject: parisc: ratelimit userspace segfault printing Ratelimit printing of userspace segfaults and make it runtime configurable via the /proc/sys/debug/exception-trace variable. This should resolve syslog from growing way too fast and thus prevents possible system service attacks.
