Subject: [PATCH 3.15 21/37] coredump: fix the setting of PF_DUMPCORE
Date: Tue, 29 Jul 2014 18:48:57 -0700 [thread overview]
Message-ID: <20140730014828.729148217@linuxfoundation.org> (raw)
In-Reply-To: <20140730014827.565626091@linuxfoundation.org>
3.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Silesh C V <svellattu@mvista.com>
commit aed8adb7688d5744cb484226820163af31d2499a upstream.
Commit 079148b919d0 ("coredump: factor out the setting of PF_DUMPCORE")
cleaned up the setting of PF_DUMPCORE by removing it from all the
linux_binfmt->core_dump() and moving it to zap_threads().But this ended
up clearing all the previously set flags. This causes issues during
core generation when tsk->flags is checked again (eg. for PF_USED_MATH
to dump floating point registers). Fix this.
