Re: sysctl should disable ECN by default
IP is a very old standard. I don't assume that all
chipsets are bug free, nor do I assume that all IP
implementations are bug free. I'm going to place blame
where it belongs, and be honest about whose bug this is.
This is not a problem with two year old equipment.
It is not the case that all IP routers made before
1999 will discard ECN traffic. Only those that reach
into your TCP header and fuss with the bits will do so.
So I am suggesting that you throw out your two year old
zyxel piece of crap "router" if you have one, or pester
their support people for the software patch, and follow
Jamal's call for volunteers as descibed on linux-kernel at:
As David noted, I'm in favor of turning ECN off-as-default.
My point is still that it should be dirt simple to turn it
on again. If you're going to quote the social contract,
then you should see the logic in respecting the user's
wishes, and not trying to disable what they've knowingly
enabled in the kernel configuration.
