Hi Ronnie,
I made small progress in ASN1 compiler too. The patch is attached.
Changes in the asn2eth compiler:
- support for value assignments (INTEGER and OBJECT IDENTIFIER are tested)
There are two new output files:
packet-xxx-val.h - values which are not exported
packet-xxxx-valexp.h - exported values
- new directive INCLUDE in conformation file
- new directive IMPORT_TAG in conformation file
It determines tags for imported type.
- all output files are created only if they are not empty
- fix for BITS STRING support

1, the imported types get class/tag == -1. I have to manually massage
the .c files and replace -1 with the proper tag/class to get it working.
No major problem,
You can use new directive IMPORT_TAG in conformation file now.
(see attached example)
but can/should say dissect_ber_sequence|set|... be
changed so that if BER_FLAGS_NOOWNTAG is set and
if class==tag==-1 then just ignore checking their values? And just pass
them on to the subdissector helper, no questions asked?
Or do you have a better solution planned?
The BER_FLAGS_NOTCHKTAG is implemented to do that but we can discuss it.
2, I think I need support for the type ANY in the compiler. This will
require changes/additions to packet-ber.c as well I think.
It might be easiest to implement it as something that is identical to
dissect_ber_octet_string but that it doesnt check the class/tag at all
and just looks at the len. then it, just as the real octet_string one,
creates a subset tvb and passes it on through teh callback, if specified.
To print the ANY fields, just use a FT_BYTES, BASE_NONE hf field and treat
it as an octet string.
I can implement it into ASN1 compiler. Could you implement is into packet-ber dissector?
I would recommend to implement the function without callback too. (the same as for octet
string)
apart from that, i managed to generate semicomplete CMS,
InformationFramework and X509AF and tied them into the partial pkinit
dissection in packet-kerberos.c and it works semi-well.

Hi Ronnie,
it seems that the mailing list does not work now.
So I send it directly to you so as you can continue with the X509.
Regards,
Tom
