Hi,
http://tools.ietf.org/html/rfc5420#section-14
14. Changes from RFC 4420 to RFC 5420
This document obsoletes RFC 4420 [RFC4420]. The only change is in
Section 3. Section 3 describes the semantic of the Length field of
the Attributes TLV.
Prior to the change, the Length field indicated the length of the
Value field only. After the change, as described in Section 3, the
Length field indicates the length of the whole TLV.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
---
In dissect_rsvp_lsp_attributes() there is a check for invalid Attributes
TLV length that is no more correct in light of changes described in
Section 14 of RFC 5420 (copied above for your convenience).
Please check this in.
Thank you
Ciao
