end of the data in the tvbuff should stop when the offset is >= the
total amount of data in the tvbuff, not when it's > the total amount in
the tvbuff following the starting offset.
In "unpack_digits()", return a null string, not a null pointer, if
there's nothing left in the tvbuff starting at the starting offset, so
that the caller doesn't have to check for a null pointer, and return an
ep_alloc()ed buffer, so the caller doesn't have to worry about freeing
the result.
If we see a filler digit, don't advance the offset in the string buffer;
we want to put the terminating '\0' right after the character we just
put into the string.

we use to determine how to interpret the token; don't bother fetching
the OID attached to the frame or conversation, as we're not using it.
Indent code in the .cnf file to match the code generated by asn2eth.
The mechListMIC in a NegTokenInit is sometimes a sequence containing a
string; check the header of the mechListMIC and dissect it as such a
sequence or as a regular item depending on whether it's a sequence or
not.
If we see a supportedMech in a NegTokenTarg, save next_level_value for
that OID with the conversation.
Dissect a responseToken in a NegTokenTarg, and a mechListMIC in a
NegTokenTarg, appropriately.
Get rid of "gssapi_dissector_handle()", and just use
next_level_value->handle - it was never being called if next_level_value
was null.
When we're dissecting a KRB5 blob, just use get_ber_identifier() to get
the header, so we don't report an ASN.1 error if there isn't a BER
identifier there; dissect the identifier and length only if we know we
have them.

and that extract IPv6 addresses into a "struct e_in6_addr", with
tvb_get_ipv4() and tvb_get_ipv6() calls - except for some that we
remove, by using proto_tree_add_item(), rather than replacing.
Have epan/tvbuff.h include epan/ipv6-utils.h, to define "struct
e_in6_addr" (not necessary to declare the tvbuff routines, but including
it there means "struct e_in6_addr" is guaranteed to be defined before
those declarations, so we don't get compiler complaints if we define it
*after* those declarations).

I attach my RTSE dissector (in tar file) which requires the included ROS dissector, as well as a patch to the latest pres.{cnf,asn}. The ROS dissector uses a new field in the SESSION_DATA_STRUCTURE to pass the ROS operation to the sub-dissector, though this is also set by other dissectors (RTSE uses it in X.410 mode).
Note that X.400 P1 in X.410 mode doesn't use ROS, so it is useful not to explicitly include ROS in my X411 dissector. However, the inclusion of a ROS dissector won't effect any dissectors that currently implement their own ROS.
I also include dissectors for:
X.411 (P1) X.400 OSI Message Transfer Service
X.420 (P22) X.400 OSI Information Object
STANAG 4406 (P772) STANAG 4406 Military Message Extensions (to P22)
These rely on the RTSE and ROS dissectors.
Withs some changes to remove various warnings and errors.

Basically the changes are:
a) [pres] make the find_oid_by_[pres_]ctx_id (I changed the name to make it more specific) non-static so it can be called from other dissectors (see acse.cnf changes). I also call it from RTSE and ROS dissectors
b) [acse] remove (#ifdef NOT_NEEDED) the oid lookup table and any reference to acse_handle - as these are no longer needed
c) [acse] register the acse dissector on 2.2.1.0.1

Small patch to ber.c
The tcap dissector has been updated to use this length. I have not tested other asn.1 dissectors to ensure that they correctly use the indefinite encoding flag instead of the length value returning zero.
There may also be some problems when re-assembly is needed, but the ability to deal with indefinite length is much more useful.
For developers the get_ber_length now returns the length of the pdu including the EOC, where you have dissectors that use packet-ber.c the eoc may need to be dealt with separately.
The tcap dissector has had numerous changes to make it less cluttered, and the useful feature of the previous version where a dialogue could be filtered out by selecting either the source or destination transaction ID has been incorporated into this version.

The generated file has a lot of indentation changes due probably to a change in asn2eth.
The underlying reason for which I added this code (dissect_ber_integer() would not add as a "filterable" field if it is larger than 4 bytes, should be handled in dissect_ber_integer() ) remains there.
Should we change dissect_ber_integer() itself to make sure that a 5 byte unsigned integer which fits in 4 bytes gets added to the tree as "filterable"?

Make those routines, and "val_to_str()", return a "const" pointer.
Update dissectors as necessary to squelch compiler warnings produced by
that.
Use "val_to_str()" rather than using "match_strval()" and then, if the
result is null, substituting a specific string. Clean up some other
"match_strval()"/"val_to_str()" usages.
Add a null pointer check in the NDPS dissector's "attribute_value()"
routine, as it's not clear that "global_attribute_name" won't be null at
that point.
Make some global variables in the AFS4INT dissector local.
Make some routines not used outside the module they're in static.
Make some tables "static const".

Register "standard" and "lock_info_col" as obsolete preferences, so
they're silently ignored rather than triggering warnings.
Propagate changes to check for "dissect_ber_octet_string()" supplying a
null tvbuff pointer from the checkins to the generated dissector ("Do
not modify this file" means "Do not modify this file"!) to the tcap.cnf
file, so that they're not lost if the dissector is regenerated. (Don't
propagate the checks for "tvb_new_subset()" returning null - it never
returns null.)
Pass -1 to "tvb_new_subset()" when appropriate.
When looping over packet data, check against the reported length, not
the captured length, so we indicate a short frame if we get stopped by
the snapshot length.
Get rid of unused variables.
