Revision 8daaf39f7f6ef53a11817f6a11ec104016c3545f authored by Arseniy Krasnov on 14 March 2023, 11:08:20 UTC, committed by David S. Miller on 16 March 2023, 17:28:23 UTC
This returns behaviour of SOCK_STREAM read as before skbuff usage. When
copying to user fails current skbuff won't be dropped, but returned to
sockets's queue. Technically instead of 'skb_dequeue()', 'skb_peek()' is
called and when skbuff becomes empty, it is removed from queue by
'__skb_unlink()'.
Fixes: 71dc9ec9ac7d ("virtio/vsock: replace virtio_vsock_pkt with sk_buff")
