Subject Re: [VOTE] Release Apache httpd 2.4.1
Date Wed, 15 Feb 2012 20:18:09 GMT
Ever contacted the owners of a network stack driver, like Microsoft, Intel
and/or Broadcom ?

They should know that they are buggy and not ASF,  special Microsoft should
know that some is buggy for HTTPD (only).

I still think:
Hardly believe that it is a driver problem, I guess more it is an http
design issue, seen it nowhere else for all that years.

I suggest to consult/hire Microsoft (believe is a ASF sponsor), they certify 
the drivers.

To be clear, again... Winsock 2.2 provides several mandatory features
which are integrated into the driver code;

1. recycling sockets (through TransmitFile and DisconnectEx)
2. accelerated kernel-based file transmission (through TransmitFile)
3. async accept-with-data (through AcceptEx)

When any one of these were incorrectly implemented by a network stack
driver, DisableWin32AcceptEx (and now AcceptFilter none) was necessary
to work around the broken driver.  That feature has always been a gross
hack around what should "just work".
