Subject: [patch 08/11] - fix signal->live leak in copy_process()
Date: Wed, 9 Nov 2005 10:37:05 -0800 [thread overview]
Message-ID: <20051109183705.GI3670@kroah.com> (raw)
In-Reply-To: <20051109183614.GA3670@kroah.com>
[-- Attachment #1: fix-signal-live-leak-in-copy_process.patch --]
[-- Type: text/plain, Size: 715 bytes --]
From: Oleg Nesterov <oleg@tv-sign.ru>
exit_signal() (called from copy_process's error path) should decrement
->signal->live, otherwise forking process will miss 'group_dead' in
do_exit().
