Fail to compile kernel, may need to increase reserved registers for spilling.
#1
Running Hashcat on Ubuntu 16.04, using the nvidia-367 and Intel i95 drivers.  It works fine when cracking MD5.  It works fine when cracking NTLMv2 so long as I'm not using rules.  As soon as I try something like:

Code:
# ./hashcat -m 5600 -a 0 /path/to/responder_hashes.txt ../WordLists/rockyou.txt  -r rules/best64.rule

I get the following:

Code:

I get the same behavior whether the NVidia drivers are enabled or not (using prime-select or directly through nvidia-settings).  It works fine in the other attack modes ... just not the one I need.

I tried both the latest release and version from git.

I have no idea what to try next.  Advice?

Clearly not an hashcat issue, the compiler error make that clear. We should ban beignet support to reduce support overhead. Can you please paste the output of hashcat -I and ideally clinfo?

After doing some more research, as I understand things, the issue is in beignet, which is how (I think) hashcat accesses the Intel chip.  What I couldn't find was a way to tell hashcat to only use the NVidia.  I think, if I could do that, I could work around the immediate issue.  Is that possible?



Interestingly, there is no "-I" option in the binary version of Hashcat for Linux.  Here it is from the version I compiled off of github:

Code:

I've pushed a new version to github which hopefully informs the use user about beignet problematic. Could you please test if the warning message shows up for you? I've also added a new precompiled beta to https://hashcat.net/beta/

In case you want to ignore the beignet device you can either use the -d or the --opencl-platforms option

This is what I get:


Code:
hashcat (v3.10-1617-g72d0b27) starting... * Device #1: Intel beignet driver detected! The beignet driver has been marked as half-baked and likely to fail kernel compilation You can use --force to override this but do not post error reports if you do so Started: Tue Nov 29 09:54:28 2016 Stopped: Tue Nov 29 09:54:28 2016

Also, I had tried the -d option before posting and, so far as I could tell, even when I skipped the Intel card, it still tried to compile against beignet.  However --opencl-platforms=2 did the trick.  CUDA cracking is working for me now.

Thanks for your help.
