This seems like an oversight.

There are multiple protocols and services that Steam and Source games have available that aren't used directly by Steam or the games but instead exist for third-party consumption. This is comparable to disabling master server queries for all just because Steam has a different server fetching method now, or removing all web apis not used by your own services.

The query protocol, including A2S_RULES, has been available in Valve's games for over ten years and is suddenly gone in CS:GO without warning.

A few things that relied on this:
- game-monitor.com and similar sites, to allow searching for servers based on server settings.
- sourcemod.ne,t to allow plugin developers to see how large their plugin's audiences are.
- match tools, to confirm that a server is running a proper match config/settings before players start playing.

That's just off of the top of my head. I'm sure that there are more.

Do server operators need S2A_RULES response from game servers? Previously S2A_RULES response included names and values of all server convars flagged as “FCVAR_NOTIFY”, but nothing in Steam uses this packet type anymore so I don’t think any services are affected.

 

If you have control of your tool(s)/webpage(s) you can stop requesting rules from the game server(s) (e.g. don’t generate PHP GetRules() request). If you really need something in response we can come up with ideas, or we can just stop spamming the console and still not respond to that packet.

 

The spew comes up because the server can no longer send more than one packet in response to a single packet external request, and if the response is exceeding MTU size the server will not send anything at all instead of sending a partial truncated packet. This is the message that is spewed to server console to inform about response that was not sent out and its estimated bytelength -

[NET] Cannot send connectionless packet to xxx.xxx.xxx.xxx:58353 '0x45' exceeding MTU (2447)

Also replying to a question asked earlier -- threaded socket processing is on by default. Official servers are operated by Valve, unless server operators install special server plug-ins game servers should no longer record or transmit client IP addresses.

 

Hope this helps,

-Vitaliy
