[Qemu-devel] [PULL 08/11] linux-user: fixed getsockopt() optlen


From: Michael Tokarev
Subject: [Qemu-devel] [PULL 08/11] linux-user: fixed getsockopt() optlen
Date: Thu, 16 Jan 2014 21:35:16 +0400

From: Pavel Zbitskiy <address@hidden>

optlen parameter of getsockopt() of type socklen_t* was read into
variable of type socklen_t, that caused zeroing out of upper 4 bytes
when running s390x on top of x86_64. This patch changes optlen type
to abi_ulong.
