Wireshark · Wireshark-users: [Wireshark-users] IPv6 VRRP checksum

[Sada Mita <sada_mita@xxxxxxxxx>]

Hello,

Sorry for the 2nd e-mail, but I'd like to hear your advice.   
I'm running 0.99.4-SVN-19188.(Running 0.99.3, the result is the 
same.)  Is the IPv6 VRRP checksum correctly written in the code?
I still see the checksum incorrect on IPv6 VRRP packet from my DUT.
Could someone check it if the code use the correct checksum.

### Here is the statement from IPv6 VRRP checksum.   
   
  5.3.7 Checksum

   The checksum field is used to detect data corruption in the VRRP
   message.

   The checksum is the 16-bit one's complement of the one's complement
   sum of the entire VRRP message starting with the version field and a
   "pseudo-header" as defined in section 8.1 of RFC2460 [IPv6].  The
   next header field in the "pseudo-header" should be set to 112
   (decimal) for VRRP.  For computing the checksum, the checksum field
   is set to zero.  See RFC1071 for more detail [CKSM].

   
###Here
 is the cut&paste from test2pcap.c
   
  static hdr_ip_t HDR_IP = {0x45, 0, 0, 0x3412, 0, 0, 0xff, 0, 0, 
0x01010101, 0x02020202};
   
  static struct {   /* pseudo header for checksum calculation */
 guint32 src_addr;
 guint32 dest_addr;
 guint8  zero;
 guint8  protocol;
 guint16 length;
} pseudoh;

   
Thanks
Sam
