Singing 2.2.0

alexsh1

I have replaced my GW with Sensebender GW 2.2.0 and immediately I can see a number of nodes failed to sign:

Shall I re-do personalisation on the nodes?

@alexsh1 https://forum.mysensors.org/topic/7843/security-migrating-from-library-version-2-1-to-2-2

alexsh1

@anticimex :(( I knew you'd say that - I have about 15 nodes
Anyway, many thanks - I have some work to be done tonight

Anticimex

@alexsh1 either that or hack the library to ignore the checksum

alexsh1

@anticimex Would you please amend the header in your 2.1 to 2.2 migration procedure - I had to clean EEPROM completely. Just running personalisation did not work sadly.

Anticimex

@alexsh1 then that's a different problem. I have verified the migration procedure and it works. Please do read carefully that you need to re do it completely. Just running the vanilla personalizer won't do anything.

alexsh1

@anticimex My bad - you have actually said it at the top "This is because in 2.2, a checksum has been added to the security data in EEPROM to avoid usage of tampered or accidentally wiped data."

:(((

I need to get my reading glasses
Sorry

alexsh1

I still have singing failed for nodes:

@alexsh1 looks like a textbook example where sender and receiver disagree on what hmac key to use.

alexsh1

@anticimex Interesting. I am using the same HMAC key on both Sensebender GW and atmega328p.

No problem if I swap the gateway for Mega.

alexsh1

@anticimex GW has got a lot of these:

!SGN:NCE:GEN

Anticimex

@alexsh1 that indicate nonce generation fails. If you use soft signing it means the backend is not initialized.
If it is not, it is indicating checksum failed. This should be visible in the early init messages.
If you use atsha, it could indicate a dodgy device communication.

alexsh1

@anticimex Sensebender GW has got ATSHA204
A few of my nodes do have ATSHA204 as well
And a few others soft signing

All of them fail after clearing eeprom and new personalisation with the same HMAC

I understand the problem is the Sensebender
Could it be a timing issue on Sensebender GW (SAMD21)?

Anticimex

@alexsh1 if it is, it is new to me. SenseBender gw has been tested with signing. Perhaps @tbowmo might know if something changed in processor frequency on 2.2 that might affect timings in the atsha driver.

@anticimex

I had to comment out this line

#define MY_SIGNING_ATSHA204_PIN   17

For SAMD21 it is connected to 20 (PA11) -> this corresponds to D0 arduino

However, the node still gives me a pain:
