For NDIS miniport drivers
If you receive a packet that is larger than the MTU, discard it. Do not indicate the packet up to NDIS (i.e., do not pass the packet to
NdisMIndicateReceiveNetBufferLists). If possible, increment theifInErrorsstatistical counter.The above rule is not affected by the
NDIS_PACKET_TYPE_PROMISCUOUSflag; do not indicate excessively-large packets even when in promiscuous mode. However, you should indicate excessively-small (aka "runt") packets when in promiscuous mode, if your hardware permits it.If you are asked to transmit a packet that is larger than the MTU, do not attempt to transmit it. Assign
NET_BUFFER_LIST::Status = NDIS_STATUS_INVALID_LENGTHand return the NBL back to NDIS withNdisMSendNetBufferListsComplete. (I wouldn't expect you to ever see such a packet; it would be a bug for NDIS to attempt to send you such a packet.)For NDIS protocol drivers
If you receive a packet that is larger than the MTU, you are free to discard it.
Never attempt to send a packet that is larger than the MTU.
For NDIS filter drivers
If a filter receives a packet that is larger than the MTU (
FilterReceiveNetBufferLists), the filter may immediately discard the packet (NdisFReturnNetBufferListsif the receive indication is not made withNDIS_RECEIVE_FLAGS_RESOURCES, or just returning immediately if the resources flag is set).If a filter is asked to send a packet that is larger than the MTU (
FilterSendNetBufferLists), the filter may assignNET_BUFFER_LIST::Status = NDIS_STATUS_INVALID_LENGTHand return the packet immediately (NdisFSendNetBufferListsComplete).Filters are not obligated to validate the size of every packet that passes through them. However, your filter should validate the size of any packets where a malformed packet would otherwise cause your filter to trigger a buffer overflow. For example, if your filter copies all ARP replies into a pre-allocated buffer, first validate that the ARP reply isn't too large to fit into the buffer. (This is not strictly necessary, since the miniport "shouldn't" give you an excessively-large packet. However, you are on the network datapath, which means you're handling untrusted data being processed by a potentially-buggy miniport. A little extra defense-in-depth is a good idea.)
Filters must not originate packets that are larger than the MTU (on either the send or receive paths).
