increasing limit of transfered bytes - kernelbug?

Dear all!

I wrote a little script which logs the amount of bytes which were transfered over a ppp-line (ADSL/PPPoE).

The problem: this only works untill you do not transfer more than 2 GB (pppd-limit) or 4 GB (kernel-limit).

Within pppd it seems that there is a problem with the $BYTES_RECVD and $BYTES_SENT variables which can be used in /etc/ppp/ip-up and -down.

PPPD uses "signed int"-counters instead of an "unsigned-int". This is not a great problem, a patch is attached to this email (thanks to Evgeni Gechev).

Unfortunately, this only increases the amount of transfered bytes to 4 GB (kernel-limit).

Is there any chance to increase the kernel-limit in feature kernel-releases?

Bye,
Michael
