Ethereal-dev: [Ethereal-dev] Re: Asn.1 and indefinite length.
Attached is a new version of packet-ber.c
which makes it able to handle indefinite length for
SEQUENCE, SEQUENCE OF and SET OF.
I have tested it with those very fev captures I do have that contains
indefinite length encodings and it seems to work but needs more
testing. In particular it needs testing to verify it hasnt caused any
regressions.
There are other contructions in ASN.1 as well in addition to SEQUENCE,
SEQUENCE OF, SET OF that can use indefinite length but I would need
example captures containing such to test with before i feel
comfortable to add it to packet-ber.c
Sid,
Do you have capture files containing FTAM protocol with or without
indefinite length encodings that I and Anders can test the pending
asn2eth autogenerated dissector with?
best regards
