[Wireshark-dev] How to handle Ethernet frames with FCS, malformed packet in PN dissector
Hi, I'm currently implementing a new pcap link-layer type which contains an Ethernet frame including the FCS (see LINKTYPE_NETANALYZER on http://www.tcpdump.org/linktypes.html). Now I have observed a problem with the PROFINET dissector, I'm not sure how to deal with it, and I'm not sure if even other dissectors are affected. From the pcap file I read: +--+ + Link_layer header+ +--+ + + + Ethernet frame data + + + +- - - - - - - - - - - + + Ethernet FCS + +--+ The WTAP dissector dissects the link-layer header and generates a new tvb subset containing only the Ethernet frame data + FCS (cuts of the link-layer header). This tvb subset is passed to the eth_withfcs dissector. In pcap_read_post_process() I added the new encap type and set the pseudo-headers FCS length to 4: case WTAP_ENCAP_NETANALYZER: pseudo_header-eth.fcs_len = 4; break; Now I open a pcap file containing a PN-PTCP DelayRes frame, which results in a malformed packet expert info exception occurred. Looking at the packet-pn-rt.c source code in dissect_pn_rt() there are some manipulations regarding pinfo-pseudo_header-eth.fcs_len and tbv reported length. If I change my assignment in pcap_read_post_process() to pseudo_header-eth.fcs_len = -1; the frame can be dissected correctly without error. Now my question: I thought I have to set pseudo_header-eth.fcs_len to 4, as the tvb contains the FCS, but this does result in false dissection of packets. Am I wrong and do I have to set pseudo_header-eth.fcs_len to -1? Will this work witch all other dissectors? Or is the behaviour a bug in the PN dissector?

Re: [Wireshark-dev] [HELP]How to dissect a packet withouta protocol? It can only be digged out by i
With this method you have to dissect the whole frame, including the MAC
addresses, ethertyp, vlan tag, etc..
Maybe someone knows another method to keep the original Ethernet header info?

Hi Nan,
you can easily register to a MAC address or any other byte in a frame
by using a heuristic dissector.
Register the dissector:
heur_dissector_add(eth, dissect_foo_heur, proto_foo);
Use this dissector function:
static gboolean dissect_foo_heur(tvbuff_t *tvb, packet_info *pinfo,
proto_tree *tree)
{
/* check if destination MAC equals 01:02:03:04:05:06 */
if ( (tvb_get_guint8(tvb, 0) == 0x01)
(tvb_get_guint8(tvb, 1) == 0x02)
(tvb_get_guint8(tvb, 2) == 0xa3)
(tvb_get_guint8(tvb, 3) == 0x04)
(tvb_get_guint8(tvb, 4) == 0x05)
(tvb_get_guint8(tvb, 5) == 0x06) )
{
/* do dissecting */
)
else
{
/* MAC does not match */
return FALSE;
}
return TRUE:
}
This works perfect for me.

[Wireshark-dev] Including new dissector to wireshark development branch
Hello, I've written a dissector for a special analyzer protocol we have developed here in my company. I'd like to ask if it's possible to include this dissector into the Wireshark development branch. If you're ok with including our dissector, maybe it would be the best if you can create a path /plugins/hilscher (name of our dissector), and I will get SVN access to this path, so we will be able to maintain the dissector by our own and the other developers don't need to worry about our dissector. If you like to see the dissector's source in advance I can send it to the mailing list if you like.

Re: [Wireshark-dev] Register dissector to MAC address

November 2007 23:13 An: Developer support list for Wireshark Betreff: RE: [Wireshark-dev] Register dissector to MAC address At first glance, packet-eth.c seems to have heuristic support, but it doesn't appear to work, at least not how I expected it to. For example, originally for the WOL dissector, I registered as I do for UDP, namely: heur_dissector_add(eth, dissect_wol, proto_wol); But registering it that way didn't work for me, so it's been changed to: dissector_add(ethertype, ETHERTYPE_WOL, wol_handle); I didn't dig too deeply into why it failed since I had a reasonable alternative, but I suppose I should have. It now seems to me to be a bug in packet-eth.c, but I'm not entirely sure, based on the comments in the code. First, compare the way a dissector like packet-udp.c tries the heuristic dissectors, using the next_tvb: next_tvb = tvb_new_subset(tvb, offset, len, reported_len); if (dissector_try_heuristic(heur_subdissector_list, next_tvb, pinfo, tree)) Now look at how packet-eth.c does it: if (dissector_try_heuristic(heur_subdissector_list, tvb, pinfo, parent_tree)) goto end_of_eth; Notice that there's no next_tvb. I assumed that this was intentional when I looked at it before, but now I'm not so sure. A bug? It now sure looks like it to me. I couldn't find any other dissectors that try to heuristically register to eth as I tried above. Perhaps because it doesn't work? If it is a bug, then once that's corrected, then that would be the better way to register both WOL and the original poster's dissector - heuristically. - Chris From: [EMAIL PROTECTED] on behalf of Stephen Fisher Sent: Mon 11/12/2007 12:50 PM To: Developer support list for Wireshark Subject: Re: [Wireshark-dev] Register dissector to MAC address On Mon, Nov 12, 2007 at 12:37:10PM -0500, Maynard, Chris wrote: Can anyone think of a reason NOT to add heuristic dissection support to packet-eth.c?

My first thought is that the original poster's dissector could be a heuristic that checks against the MAC address when deciding whether to acccept the packet or not.
