The intent at the time was that modification and distribution of modified versions were prohibit. The Bacula version clearly has been modified (at least in a minor way, didn't check further). I'm surprised that upstream doesn't see that. The code has since been republished as RFC 6234: <https://tools.ietf.org/html/rfc6234> This time, there is a provision for extract of code parts: This document is subject to BCP 78 and the IETF Trust's Legal Provisions Relating to IETF Documents (http://trustee.ietf.org/license-info) in effect on the date of publication of this document. Please review these documents carefully, as they describe your rights and restrictions with respect to this document. Code Components extracted from this document must include Simplified BSD License text as described in Section 4.e of the Trust Legal Provisions and are provided without warranty as described in the Simplified BSD License. The referenced section reads: License. In addition to the licenses granted under Section 3, unless one of the legends contained in Section 6.c.i or 6.c.ii is included in an IETF Document containing Code Components, such Code Components are also licensed to each person who wishes to receive such a license on the terms of the “Simplified BSD License", as described below. If a licensee elects to apply the BSD License to a Code Component, then the additional licenses and restrictions set forth in Section 3 and elsewhere in these Legal Provisions shall not apply thereto. Note that this license is specifically offered for IETF Documents and may not be available for Alternate Stream documents. See Section 8 for licensing information for the appropriate stream.

The apparent intent, as evidenced by the copyright statement in the source code parts of RFC 6234, is that the code parts are available under that licensing option, even though they are not otherwise marked as code components under the TLP.
