[PATCH 4.4 21/36] vsock: fix timeout in vsock_accept()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Stefano Garzarella <sgarzare@xxxxxxxxxx>

[ Upstream commit 7e0afbdfd13d1e708fe96e31c46c4897101a6a43 ]

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().
