Hi Ankitha,
What the value of event_fields ?
Do you have look other dissector use proto_tree_add_bitmask ? (packet-gsm_sim.c or packet-ieee80211.c )

Hi
I am currently working on developing of MIH protocol plugin. I am
using proto_tree_add_bitmask and getting the error in the packets as -
17:55:33 Warn Dissector bug, protocol MIH, in packet 8:
proto.c:7166: failed assertion "len * 8 == hf->display"
What may be the error?
The following is the definition of the datatype where the error occurs-
{
&hf_event_link_detect,
{
"MIH LINK Detected",
"mih.event_list.link_detect",
FT_BOOLEAN,
1,
NULL,
LINK_DETECT_MASK,
NULL, HFILL
}
}
and the call to the function is like this-
evt_list_tree = proto_item_add_subtree(tlv_tree, ett_event_bitmap);
proto_tree_add_bitmask(evt_list_tree, tvb, offset, hf_event_list,
ett_event_bitmap, event_fields, ENC_BIG_ENDIAN);
-->hf_event_list is defined this way-
{
&hf_event_list,
{
"List of Events",
"mih.event_list",
FT_UINT32,
BASE_HEX,
NULL,
0x0,
NULL, HFILL
}
},
Let me know if any extra info is required.
NB:I am sorry for duplicating the mail, but the problem is a little
urgent.
Regards
Ankith
