The following errata report has been verified for RFC8163, "Transmission of IPv6 over Master-Slave/Token-Passing (MS/TP) Networks". -------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid5996 -------------------------------------- Status: Verified Type: Technical Reported by: Kerry Lynn <kerlyn@ieee.org> Date Reported: 2020-02-27 Verified by: Erik Kline (IESG) Section: Appendix B. Original Text ------------- /* * Sanity check the encoding to prevent the while() loop below * from overrunning the output buffer. */ if (read_index + code > length) return 0; Corrected Text -------------- /* * Sanity check the encoding to prevent the while() loop below * from overrunning the output buffer. */ if (code == 0 || read_index + code > length) return 0; Notes ----- This was submitted as a change to [BACnet], Annex T, by James Butler. The normative procedure for decoding COBS is correct in [BACnet], 9.10.3.2(a) but this bug appears in the informative example in Annex T. Since the purpose of COBS encoding is to eliminate all zero bytes from the data, the presence of a zero indicates an error. -------------------------------------- RFC8163 (draft-ietf-6lo-6lobac-08) -------------------------------------- Title : Transmission of IPv6 over Master-Slave/Token-Passing (MS/TP) Networks Publication Date : May 2017 Author(s) : K.
