CVS commit: src/sys/net

Module Name:    src
Committed By:   alnsn
Date:           Wed Aug 15 20:59:51 UTC 2012

Modified Files:
        src/sys/net: bpf.c

Log Message:
Fix two bugs introduced by recent commit.

 - When handling contiguous buffer in _bpf_tap(), pass its real size
   rather than 0 to avoid reading packet data as mbuf struct on
   out-of-bounds loads.
 - Correctly pass pktlen and buflen arguments from bpf_deliver() to
   bpf_filter() to avoid reading mbuf struct as packet data.
   JIT case is still broken.

Also, test pointers againts NULL.
