3.2.87-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <eduma...@google.com>
[ Upstream commit e551c32d57c88923f99f8f010e89ca7ed0735e83 ]
At accept() time, it is possible the parent has a non zero
sk_err_soft, leftover from a prior error.
Make sure we do not leave this value in the child, as it
makes future getsockopt(SO_ERROR) calls quite unreliable.
