TLV81 encoding issue. DOCSIS 3.1 SSD #54

Closed jforhan closed 7 years ago

jforhan commented 7 years ago

"docsis_symtable.h" has TLV81 as "encode_nothing". It should be able to encode it just fine as a hex string. TLV82 is set to encode as hex.

M-CVC: config file contains a Manufacturer CVC (TLV 32) Co-CVC: config file contains a Cosigner CVC (TLV 33) M-chain: config file contains a Manufacturer CVC-chain (TLV 81) Co-chain: config file contains a Cosigner CVC-chain (TLV 82)

32/33 are for legacy modems (DOCSIS 1.x,2.0 & 3.0). For DOCSIS 3.1 a chain of certs is required (TLV81/82) rather than just the MfgCVCData.

The firmware I have is not co-signed so I need to be able to encode TLV81.

Confirmed that if I change docsis_symtable.h to "encode_hexstr" for TLV81 and recompile it encodes TLV81 correctly and D3.1 modems upgrade their firmware.

@jforhan, does that commit match the change you made?

jforhan commented 7 years ago

Yes, this is the same as the change I made.
