From 6826a68d673ed0a5b678453e0677db66c79fce0b Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=A9mie=20Galarneau?= Date: Sat, 14 Sep 2019 16:02:33 -0400 Subject: [PATCH] sessiond: fix: possible unaligned access in packed structure MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit '&rsock->sock.fd' is passed to consumer_send_fds and may result in an unaligned pointer value. Use the ALIGNED_CONST_PTR macro to create an aligned copy of the fd that is being passed.
