copy-paste from ESR thread:
- significant memory usage reduction for dedicated servers (2x-6x times) + reduced CPU usage
- no external dependencies, no SDL (and related regressions)
- native ALSA support for linux
- faster and safer QVM (Quake Virtual Machine) - means higher FPS, less lags
- reworked dedicated console for win32
- server auto-restart for long non-stop game series (no need for restart scripts at all)
- support for cpma/cnq3 color codes (8,9,a-z) in console
- unlagged raw mouse input (win32, enabled automatically for \in_mouse 1)
- \dlmap, \download - fast and easy map downloads from ws.q3df.org (by default)
- \cl_conColor [RRR GGG BBB AAA] - custom console color
- \in_minimize hotkey to fast minimize/restore (windows-only)
- \r_neatsky - nopicmip for skyboxes
- \r_ext_multisample 0|2|4|6|8 - multi-sample anti-aliasing
- \r_bloom
- \r_dlightMode 1|2 - new per-pixel dynamic lights, requires opengl 1.4 (radeon 8500+, FX5200+) - means it will work event on hardware from 2001
- \varfunc - advanced cvar modifier
- many other bugfixes and improvements

BTW, my fix for https://cve.mitre.org/cgi-bin/cvename.c ... -2017-6903 is much more correct than in ioquake3

What kind of traffic they generate: connectionless packets etc.? I need to know what kind of data causing this or at which stage attack is coming. So I will know what part of engine should be patched. For example I can try to backport this: https://github.com/JACoders/OpenJK/pull/832

That might be what was happening.
It was taking huge amounts of bandwidth (all of my ISP's upstream), and affected other servers on the same rack.

This attack was not just LAN based. and seemed to act like a Botnet where innocent users became the attacker.
Using alternative game ports (ie, 30320) would not work,they'd still attack on that.

Then IOQ3 introduced an improved network protocol (in their test builds) but I haven't found if this actually helps deters the attacks. I wouldn't want to put a server box at risk under a false sense or security.

I'm never experienced such problems. However as long as it is engine flaw an you can reproduce attack - it can be fixed.

Are these versions of 1.32e DDoS protected?, has it been tested?.

I want to run a Q3 service but unable to due to the nonstop DDoSing that engine has.
I have asked on IOQ3 forums but have not received any answers, just a link to one person who was using IOQ3 but was still DDoS'ed (UDP packet spoofed).

IOQ3 offers an option to use a different networking protocol (71), not sure if this works though.

This is hack on QVM bytecode level - I'm disabled whole functions in CPMA code so now its something like a bit 'blind'

Re: Quake3 1.32e

Any explanation on - overwhelming CPMA hack? Sounds a bit devious :>

Btw, from a total stranger, nice work on this and thankyou :)
