From b8ab854b27e9b88d9b85b4c572049b29cb96de43 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marc-Andr=C3=A9=20Lureau?= Date: Fri, 19 Jun 2015 13:00:32 +0200 Subject: [PATCH] ivhsmem: read do not accept more than sizeof(long) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit ivshmem_read() only reads sizeof(long) from the input buffer. Accepting more could lead to fifo8 abort() on 32bit systems if fifo is not empty. A following patch will change the protocol to 64-bit little-endian instead.
