hi, thanks for testing the patch, I will look into the openmp related details in the code and make the next patch fully functional (atleast for generic build for now). Cheers,
Deepika

I trust you about the Test Suite so did not check now. But something seems to be amiss with OMP:
Jumbo-5:
Benchmarking: MSCHAPv2 C/R MD4 DES [mschapv2]... DONE
Many salts: 2330K c/s real, 2330K c/s virtual
Only one salt: 1570K c/s real, 1570K c/s virtual
Benchmarking: MSCHAPv2 C/R MD4 DES [mschapv2]... (2xOMP) DONE
Many salts: 4200K c/s real, 2121K c/s virtual
Only one salt: 2717K c/s real, 1372K c/s virtual
Bitslice:
Benchmarking: MSCHAPv2 C/R MD4 DES [DES_BS_MSCHAPv2]... DONE
Many salts: 4488K c/s real, 4488K c/s virtual
Only one salt: 2280K c/s real, 2280K c/s virtual
Benchmarking: MSCHAPv2 C/R MD4 DES [DES_BS_MSCHAPv2]... (2xOMP) DONE
Many salts: 2946K c/s real, 1480K c/s virtual
Only one salt: 2077K c/s real, 1044K c/s virtual
The very last benchmark of the above indicates a bug: "Virtual" for OMP should ideally be close to the one for non-OMP. And real should ideally approach 2x virtual. In any case it should not be slower than non-OMP.
Also, for your next patch I think it's time you add a copyright notice like explained in http://openwall.info/wiki/john/licensing
