[PATCH net] vsock: fix timeout in vsock_accept()

From: Stefano Garzarella
Date: Wed May 27 2020 - 03:57:08 EST


The accept(2) is an "input" socket interface, so we should use
SO_RCVTIMEO instead of SO_SNDTIMEO to set the timeout.

So this patch replace sock_sndtimeo() with sock_rcvtimeo() to
use the right timeout in the vsock_accept().

Fixes: d021c344051a ("VSOCK: Introduce VM Sockets")
