Message-Id: <20171212124432.515271179@linuxfoundation.org> Date: Tue, 12 Dec 2017 13:44:02 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Heiko Carstens <heiko.carstens@...ibm.com>, Martin Schwidefsky <schwidefsky@...ibm.com> Subject: [PATCH 4.9 032/148] s390: fix compat system call table 4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Heiko Carstens <heiko.carstens@...ibm.com> commit e779498df587dd2189b30fe5b9245aefab870eb8 upstream. When wiring up the socket system calls the compat entries were incorrectly set. Not all of them point to the corresponding compat wrapper functions, which clear the upper 33 bits of user space pointers, like it is required.
