>From d92b4befe07c6a1e852e4462126a5443342448cd Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu <sukadev@xxxxxxxxxxxxxxxxxx> Date: Tue, 21 Oct 2008 18:00:01 -0700 Subject: [PATCH] kill sig -1 must only apply to callers namespace Currently "kill <sig> -1" kills processes in all namespaces and breaks the isolation of namespaces. Earlier attempt to fix this is discussed at: http://lkml.org/lkml/2008/7/23/148 but nothing seems to have happened since then. This patch uses the simple fix suggested by Oleg Nesterov.
