Hello,
The problem seems to be in the per decoder, probably
dissect_per_octet_string
in the case
} else if ((min_len==max_len)&&(min_len<65536)) { /* 16.7 if
length is fixed and less than to 64k*/
...
if (is_per_byte_aligned){
BYTE_ALIGN_OFFSET(offset);
val_start is not updated, and if the offset was not aligned from the
start, val_start points to the previous byte
if (is_per_byte_aligned){
BYTE_ALIGN_OFFSET(offset);
+ val_start = offset>>3;
val_length = min_len;
offset+=min_len*8;
seems to fix it, but it would be better if somewone with deeper knolwdge
about packet-ber takes a look at it
btw it would be nice to replace "per_aligment_type_callback" with
"per_alignment_type_callback" in the sources

Hello,
While trying few captures with the current svn, I noticed that ip
addresses and GUIDs are decoded incorrectly.
example:
we have source signall address element that looks like this:
00 01 02 03 04 05 06
where 0 means ipAddress and the IP should be 1.2.3.4 port 0x0506
but it's decoded instead as 0.1.2.3 port 0x0506
the same thing goes for the CallIdentifier -
00 01 02 .... (17 bytes) is decoded like guid 000102..., and it should
be 010203...
Tested on two different linux systems. Unfortunatrly I'm not too much
into asn1 and don't have idea how to debug this further.
best regards,
Cvetan
