3. Raspberry Gateway 2.1.1 + signing

Raspberry Gateway 2.1.1 + signing

  • t3chie

    The Gateway code on Raspberry seems to work only when signing is not used.
    Is that something known?

    In addition, I had to explicitly name the architecture and comment out one line in core/MySigningAtsha204Soft.cpp to get the debug signing output working:

    #ifdef linux
    #define __FlashStringHelper char
    // #define MY_SERIALDEVICE.print debug
    #endif

    My configure options were:
    ./configure --my-gateway=ethernet
    --soc=BCM2836
    --my-transport=nrf24
    --my-rf24-ce-pin=22
    --my-rf24-cs-pin=24
    --my-rf24-irq-pin=15
    --my-rf24-pa-level=RF24_PA_LOW
    --my-leds-err-pin=12
    --my-leds-rx-pin=16
    --my-leds-tx-pin=18
    --my-signing=software
    --my-signing-request-signatures
    --my-signing-request-gw-signatures-from-all
    --my-rf24-encryption-enabled
    --my-rf24-channel=70
    --my-debug=enable
    --my-signing-debug

    Tested with a Raspberry 1 and 2.

    @t3chie hi, this is not known (at least to me). I don't have a rPi setup so I have not been able to verify. @marceloaqno do you know what the current status is? If I remember correctly, you tested the latest signing improvements package successfully on rPi, right?

    @t3chie btw, the option my-signing-request-gw-signatures-from-all is obsolete. It is the default behavior now. At least if you are on latest development branch.

    @Anticimex I am happy to test whatever you want me to do. I "think" my wiring is correct as it works when signing is not used. I can post debug output from the Gateway for both (signed and unsigned) if that helps.
    Should I give the dev branch a try?

    @t3chie ah you are on master? That's interesting because that should work. Yes, please give the devel branch a try. Could be that full signing support for rPi never made it in the latest release.

    @Anticimex That is different but still not working. The architecture autodetection works. The signing debug does compile, too. But when I am starting up a node the gateway reports:

    The only node on that radio channel is ID 100 and if I disable signing, the same setup is reporting:

    @t3chie looks like the personalization has not finished successfully. How do you store the hmac key to the rPi? If you don't use the personalizer sketch you either need to write the checksum yourself or disable the checksum validation. It could be that the method for personalizing on rPi does not calculate and store a checksum. So either that has to change, or the checksum check should be disabled on rPi/Linux.

    @Anticimex Sorry for that - when I changed Pi's I forgot to personalize the GW. But that didn't made it working:

    @t3chie it still reports !SGN:PER:TAMPERED so my original question(s) are still valid 🙂

    @Anticimex I use:

    ./bin/mysgw --set-soft-hmac-key D94AB9BF54D266CA517C23C870FF7A6...
    ./bin/mysgw --set-soft-serial-key 2200002200...

    How can I calculate the checksum or disable it?

    @t3chie just comment https://github.com/mysensors/MySensors/blob/development/core/MySigningAtsha204Soft.cpp#L127

    I'm pretty sure the problem is that on Linux, a checksum is never calculated, so I will patch the init function of the software signing backend to ignore that calculation on Linux.
    I do also note that you seem to get NACKs. I can already now say that those have to go away for signing to work. See here.

    @Anticimex Have tried to comment out line 127, but as you said no joy. I know that the radio I am using is not the best but I am still not sure if the HW is the culprit here.

    I have put that RF24 module onto a Nano with itead RF Shield and loaded a 2.1.1 Gateway Sketch including signing - that works against the same node I am testing the Pi.
    I am using the interrupt variant of the Pi cabling - could that be the problem?

    @t3chie if you read the troubleshooting guide which I linked to, the topmost and most common issue is radio problems and these are not signing related. They are because you have a flaky radio connection (reasons could be many, and there are a ton of threads on the forum that discuss these). You see these when you enable signing because then full size messages are transmitted and not the relatively small messages you typically transmit.

    @Anticimex Well, I have read all troubleshooting material many times and agree that mostly it is HW. This time however it was stupidity on my side!
    I mixed up signing with encryption on the Pi compile time flags.
    To summarize:
    On 2.1.1, the architecture needs to be set and signing works (have not tested encryption yet).
    On dev, architecture needs to be left alone (not set) and checksum calculation needs to be commented out (line 127 of MySigningAtsha204Soft.cpp).

    @t3chie ah, ok. Yes, those NUS messages indicated that something was really mixed up 🙂
    I will file a pull request to fix the checksum issue. Thanks for reporting!

    @t3chie I think so. There are a few errors in the log though but I am not sure if that is due to other nodes on your network not being configured properly.

    @t3chie it also looks like your gw is not always succeeding in generating nonces.

    @t3chie could you please include the startup messages from the gateway? Looks like it still does not initialize properly. It should not have a problem generating nonces if it thinks personalization is OK.

    @t3chie hm, odd. And you get the validation message twice. I must have messed something up. I'll have a closer look tonight and get back to you. Thanks for helping out!

    @t3chie I believe I found the issue on my pr. Sloppy coding is all I can say... I will notify you once I have resolved it. In the meantime you can delete your copy of my branch (I tend to force push to my pull requests).

    git checkout development
git branch -D fallberg-signing

    @t3chie I've pushed updates now. It should resolve the problems. I accidentally excluded the part where the backends are initialized, and there are safeguards against that so it refused to calculate nonces for signing. You should now get a "SGN:INI:BND OK" after "SGN:PER:OK"

    Hi guys,
    I read this thread because it was the only the search found ("raspberry signing").
    I'm building a gw (the plan is raspberry 3, rf24). Since it's in a populated area, I want signing (my other project is remote, so no real worries there).
    I'm trying to figure out the configuration part for the Raspberry and some of the options:
    -software signing AND rf24 encryption. Two different things, right? I thought I would just use signing if that's adequate.
    -does master branch work or must I use dev? What's the difference in everyday use?
    -I think pin 7 is usefully located (pro mini) and A5 and A6 less convinient, can I use those for the signing?

    Also, is there a guide or a thread for a noob regarding setting this up? If not, should we start a new thread?

    Thanks guys. I like the info here.

    @MasMat hi, well, ./configure --help should give you a list of configuration options.
    To my knowledge signing on rPi uses no pins as it is software based and uses the Linux random number generator. So Arduino specific pins make no sense on a rPi.
    For Arduino configurations and signing and encryption in general, there is a signing thread on this forum and the first post of that thread links to doxygen documentation that describe the exact details for both the official MySensors version and the beta version.
    See https://forum.mysensors.org/topic/1021/security-introducing-signing-support-to-mysensors

    @Anticimex Whew! Not a light read that thread. Esp for someone noobish like me. Also it has a lot to do with ATSHA and I was thinking I'd do just software signing.

    The pin idea was for the config - to be used for other nodes. Not gw.

    The quick questions: do I have to use dev branch?
    This way I'll be able to get going and see what roadblocks I hit.

    @MasMat a generic pin config for the nodes depend on whether you use identical nodes, as the pin assignment is hw specific.

    Regarding signing on rPi, try searching the forum. It has been discussed before, and I don't use rPi myself so I don't remember the exact flags, nor do I remember if the full support for signing on rPi made it into the latest release.
    I know a new release is about to come though.

    Thanks. I'll keep looking then.
    Most likely my nodes will be almost alike, so that's why I'd rather choose a pin that I hardly ever would use (as opposed to default pin 7).
