This patch set fixes two bugs and adds rate-limiting for DCCP-Syncs. Patch #1: Uses variables instead of a reference to skb fields; it is needed by patch #2 (no code change here). Patch #2: Fixes the Sync/Reset flood bug discussed earlier on dccp@vger, by adding the special case for sequence-invalid Reset from RFC 4340, 7.5.4. Patch #3: Renames `seq' parameter of dccp_send_sync into `ackno'. Patch #4: Implements rate-limiting for DCCP-Syncs. Patch #5: Adds another exception required by RFC 4340, 7.5.4 - In state REQUEST, receiving a Sync generates a Reset and not a SyncAck. - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
