[LUAU] Trying to disable UDP checksum using Debian Testing

[Matthew John Darnell]

Aloha,

I am using Debian testing version and am trying to disable udp checksum.

I have tried

optval=1;
if (setsockopt(sock_info - socket, SOL_SOCKET, SO_NO_CHECK, (void*)optval,
sizeof(optval)) ==-1)
{
 LOG(L_ERR, ERROR: udp_init: no checksum setsockopt: %s\n,
strerror(errno));
}

Even with the code, I continue to get an EAGAIN error when there is a
checksum error.

Can anyone point me in the right direction?

Aloha,
Matt

I guess I am not alone with this issue.  Here is a post describing the exact
problem.

Thinking even more about it, most layer 2 technology is quite reliable and
real udp checksum error rarely happens in most networks. I doubt that it is
going to be a big negative impact on the system. Actually it would speed up
the system a little bit.
