4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Eric Dumazet <edumazet@xxxxxxxxxx> [ 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.
