seg fault on missing DeviceProxy_LibUSB.so

Question

seg fault on missing DeviceProxy_LibUSB.so

Building newest github master on your prior BBB image resulted in:

root@arm:/home/debian/USBProxy2/USBProxy-master/src# ./usb-mitm
SIGRTMIN: 34
error opening library
Segmentation fault
root@arm:/home/debian/USBProxy2/USBProxy-master/src#

I tracked this down to a missing .so file and built it manually:

root@arm:/home/debian/USBProxy2/USBProxy-master/src/Plugins/Devices# gcc -c -fPIC DeviceProxy_LibUSB.cpp -I../../include
root@arm:/home/debian/USBProxy2/USBProxy-master/src/Plugins/Devices# gcc DeviceProxy_LibUSB.o -shared -o DeviceProxy_LibUSB.so

Then line 35 in ./lib/PluginManager.cpp from:

    void* DeviceProxyPlugin = dlopen(string("plugins/DeviceProxy_LibUSB.so").c_str(), RTLD_LAZY);

to:

    void* DeviceProxyPlugin = dlopen(string("Plugins/Devices/DeviceProxy_LibUSB.so").c_str(), RTLD_LAZY);

allowed a good start, and was able to proxy my mouse and log some output:

root@arm:/home/debian/USBProxy2/USBProxy-master/src# ./usb-mitm -l

Fixed.

I fixed this when you reported it, but I forgot to close the issue. Thanks for the contribution.

I'm getting the same issue. Above solution does not work for me.

Answer 3 · 2014-08-25T16:20:31.000Z

The way that plugins are stored and loaded has changed since this bug was opened/fixed, so the solution to it probably won't be valid for your issue.

What is stored in /usr/local/lib/USBProxy/? Are there a number of plugin .so files?

Answer 4 · 2014-12-08T20:13:21.000Z

I'm also getting this issue with a brand new clone. If there's anything I can to do help fix it let me know.

Answer 5 · 2014-12-09T05:04:28.000Z

@Iskuri Could you send me the output? This may be a different issue with the same outcome.

Could you try going back to a commit before I started doing silly things with python bindings?

Answer 6 · 2014-12-09T08:06:45.000Z

@dominicgs here is the compiler output and output from when I run the command. I discovered this morning that I was actually compiling on an older version of the code, and when I compiled on the fresh clone I pulled down I didn't get a segfault but I still got the "error opening library /usr/local/lib/USBProxy/DeviceProxy_LibUSB.so" so the issues may be unrelated at this point. Anyway, here's what I got, if it helps.

Answer 7 · 2014-12-10T10:41:55.000Z

Did you run make install after building? Could you run ls /usr/local/lib/USBProxy/ and check which plugins are installed?

The plugin loader expects the plugins to be in a specific place. It's on my todo list to fix this and have them picked up from a location that is either set at compile time or user specified, but my todo list is very long.

I also had this problem once. I think the software should not crash, but display a message
about it and exit anyway.

Maybe I will fix a few of these tiny issue the next days.

In 2015 I have a new project for the same customer for which I used this software before.
I guess there will be more patches from my side later on. At least I will make the Intel
Edison board work as well some point in time.

Kind regards,

Answer 9 · 2014-12-10T10:48:19.000Z

Isn't that what it does? It gives an error message about not finding the .so and then exits cleanly as well as logging the contents of the config object.

Answer 10 · 2014-12-10T10:49:00.000Z

@jaapcrezee I would very much appreciate any patches that you would be willing to provide, especially if they add support for more hardware platforms.

I thought I had at least once seen a segfault there.
Will check it later :)

I had hoped that I had fixed that issue, but if you still see it I would be very happy to try to fix.

Thanks,
Dominic

Answer 13 · 2014-12-10T11:00:16.000Z

Hi Dominic,

I definitely ran make install. Unfortunately, I'm at work right now so can't check that directory but will definitely do it as soon as I get home. If your to-do list keeps growing I'd be really happy to help in any way I can, especially as this project can help me with almost all the projects I'm working on.

Chris.

Answer 15 · 2014-12-10T19:58:22.000Z

As expected, it's not installed. Sorry for asking you to list out the directory, I should have seen from the build output that it wasn't built.

Are you using the OS image from the GitHub releases page? What is the output when you run cmake .. from a clean build directory?

I suspect that it wasn't built because it couldn't find libUSB 1.0 on your system.

Can you also give the output of the usb proxy binary when starting?

And maybe a strace log, maybe also ltrace?

Hi, I didn't realise that there was an image on the releases page. I was using a stock image from the beaglebone black website and using that. Would you like me to download that image and give it a go?

@jaapcrezee I'll provide the strace and ltrace if all else fails, as it seems that it may be unnecessary.

@Iskuri It looks like you don't have libUSB 1.0 installed, most Linux distros still come with older versions. We can't use the standard libUSB because we want some more recent features (this should change very soon).

I would recommend using the image from the release page, it has a kernel patch and some configuration set up to make things a little easier. You will also need to connect to it over ethernet as we have to disable the USB networking when using USBProxy.

That's really weird, because I thought I'd installed it, I gave it a go with the standard one and one compiled from source. I'm flashing the image now and will let you know how it goes in a few minutes.

No problem, glad it's working.

@jaapcrezee I'm going to close this bug now, but you can reopen it any time if you see segfaults again.

Try installing libusb-1.0.0-dev. Worked for me.
