I'm trying to output some bit values in my wireshark dissector decode.
However, I want to be able to filter based on those bit values.
I can't seem to use the LUA bitop library to do it, because lua
complains that the result is not a uservalue.
I've got the following code:
for shred = 1, num_shreds
do
subtree:add("----- NV Storage Shred " ..
shred .. " -----")
subtree:add(fields.shred_id,
buffer(offset, 8))
subtree:add(fields.shred_flags,
buffer(offset+8, 8))
local
flags=tonumber(tostring(buffer(offset+8,8):uint64()))
local
hex=tostring(bit.tohex(bit.band(flags,0x02)))
subtree:add("----- NV Storage hex flags:
" .. hex)
local hexba=ByteArray.new(hex)
-- The following line complains about a nil
uservalue
local rdonly=Tvb.new_real(hexba, "hex")
-- The following line complains about the
value being a number instead of a uservalue
subtree:add(fields.shred_rd,
bit.band(flags, 0x02))
offset=offset+inc
end
Does anyone happen to have any clues as to what I'm doing wrong? Fwiw,
I'm using 1.2.0 (1.3, 1.4, and 1.5 all have video corruption issues, and
1.0 has issues with 64-bit integers).
Thanks.
