Hi all, I am using linuxmodule click-1.7 over linux-2.6.24.7 (but this is also the case with linux-2.6.18.2) If I send packets of 1480 bytes and with the default mtu of 1500, the the buffer size allocated at the receiver is of 1664, (p->buffer_length()= 1664 ) which is fine. However, when I send large packets of more than 1500 bytes, and set the mtu to a value > 1500, the buffer allocated at the reception is always of 256 ((p->buffer_length()= 256)) whatever the packet size is. So, if I want to access to the data stored beyond the 256 bytes in that packet, the data I get is erroneous. So i am wondering if there is a limitation on the maximum buffers size? where this limitation is hard-coded? and why does it change with the mtu?
Thanks for helping Ps: Click scripts are roughly : Sender : RatedSource ->UDPIPEncap -> EtherEncap -> ToDevice(eth0) Receiver: FromDevice(eth0) -> Myelement -> Discard In Myelement, I only get p->buffer_length() and p-> data() and p->end_data() Manel BOURGUIBA PhD Candidate PHARE - LIP6 - UPMC - Sorbonne Universités BC169 - Office 25/26-319 4 place Jussieu 75252 PARIS cedex 05 +33 1 44 27 61 88 _______________________________________________ click mailing list [email protected] https://amsterdam.lcs.mit.edu/mailman/listinfo/click
