Yes, right! I'll reorder patches and fix VMCI patch after reply from @Vishnu Thanks, Arseniy > > Thanks, > Stefano > >> >> diff --git a/net/vmw_vsock/af_vsock.c b/net/vmw_vsock/af_vsock.c >> index 5f2dda35c980..413407bb646c 100644 >> --- a/net/vmw_vsock/af_vsock.c >> +++ b/net/vmw_vsock/af_vsock.c >> @@ -2043,7 +2043,7 @@ static int __vsock_stream_recvmsg(struct sock *sk, struct msghdr *msg, >> >> read = transport->stream_dequeue(vsk, msg, len - copied, flags); >> if (read < 0) { >> - err = -ENOMEM; >> + err = read; >> break; >> } >> >> @@ -2094,7 +2094,7 @@ static int __vsock_seqpacket_recvmsg(struct sock *sk, struct msghdr *msg, >> msg_len = transport->seqpacket_dequeue(vsk, msg, flags); >> >> if (msg_len < 0) { >> - err = -ENOMEM; >> + err = msg_len; >> goto out; >> } >> >> -- >> 2.25.1 >> >

This removes behaviour, where error code returned from any transport was always switched to ENOMEM. This works in the same way as: commit c43170b7e157 ("vsock: return errors other than -ENOMEM to socket"), but for receive calls.
