Subject: [Qemu-devel] [PATCH] linux-user/syscall.c: Let lv always match val in do_getsockopt()
Date: Thu, 14 Jan 2016 14:24:24 +0800 [thread overview]
Message-ID: <1452752664-11818-1-git-send-email-chengang@emindsoft.com.cn> (raw)
From: Chen Gang <chengang@emindsoft.com.cn>
After host_to_target_sock_type(), the length of val may be changed, so
calculate the related lv, too.
