Subject: [PATCH 0/4] swapper fixes (Was: kernel panic on kill(0, SIGTERM) with PGID == 0)
Date: Mon, 10 May 2010 21:49:17 +0200 [thread overview]
Message-ID: <20100510194917.GA5249@redhat.com> (raw)
In-Reply-To: <4BE7B3BD.70901@secunet.com>
Hello,
Mathias Krause reports that a buggy (or special) /sbin/init can
crash the kernel if it sends a signal to its pgrp/sid before it
changes its initial (0,0) pids. See the changelog for 1/4.
git-bisect blames "start the global /sbin/init with 0,0 special pids"
commit 430c623121ea88ca80595c99fdc63b7f8a803ae5, but in fact the
problem was caused by another change, see 2/4.
The patches do not depend on each other, 3/4 fixes another problem,
4/4 is purely cosmetic.
Oleg.
