gpg-opencl [SHA1 OpenCL] crashes on newer MESA radeon/ampgpu driver. #2204

Closed clinew closed 8 years ago

clinew commented 8 years ago

First issue that I ran into was the following error:

frostsnow@seneca ~/software/JohnTheRipper/run $ ./john -test --format=gpg-opencl
Will run 8 OpenMP threads
Device 0: AMD HAWAII (DRM 2.45.0 / 4.7.0, LLVM 3.8.1)

Build log: In file included from input.cl:14:
/home/frostsnow/software/JohnTheRipper/run/kernels/opencl_misc.h:128:26: warning: unknown OpenCL extension 'cl_amd_media_ops' - ignoring

Error -11 building kernel $JOHN/kernels/gpg_kernel.cl. DEVICE_INFO=10
OpenCL CL_BUILD_PROGRAM_FAILURE error in common-opencl.c:1053 - clBuildProgram failed.

...which was fixed by going into run/kernels/gpg_kernel.cl and removing the inlineattribute. The same for functions in run/kernels/opencl_sha1_ctx.h.

After that, running ./john -test --format=gpg-opencl passes with:

Will run 8 OpenMP threads

...but then doing an actual run causes the GPU to lockup and crash the driver. I'm not sure where the source of the of the problem is. Any idea where I can start looking to debug?

The command I'm using is: ./john --wordlist=mywordlist --rules=mycustomrules mygpgkey.asc --format=gpg-opencl

Various system information is as follows:

        Kernel driver in use: radeon

Though the README-OPENCL warns against using the "X11 opensource" drivers, I'm not sure how that warning fits into the new amdgpu integration. I also ran piglit to sanity-check OpenCL and it went pretty well with 927 passes, 14 fails, and 12 skipped tests.

Finally, the monstrous kernel crash:

At this point I have no idea if the issue is in the OpenCL code itself, the kernel driver, or LLVM/clang.

magnumripper commented 8 years ago

You could try forcing lower GWS and see if it helps. Run with --verb=5 and see what GWS it ended up with. Then re-run prefixing the whole command line with GWS=<half of that> eg:

GWS=512 ./john --wordlist=mywordlist --rules=mycustomrules mygpgkey.asc --format=gpg-opencl

If it still crashes, halve it again (and so on).

On a side note: Is inline not supported by MESA at all, or did removing it just happen to make the build error go away?

Interesting. I was expecting to see amdgpu (xf86-video-amdgpu) loaded. Have you tried to blacklist radeon or uninstall xf86-video-ati?

clinew commented 8 years ago

@magnumripper: Setting GWS to 131072 seems to have fixed it! (It was coming up with 225280 by default).

Regarding inline, I don't know the root cause, only that removing it seems to have fixed the problem. I'd guess that the symbols are being stripped when the functions are inlined, causing linkage problems down the road.

@claudioandre: As I recall from when I was desperately trying to get the amdgpu driver working after giving up on fglrx so that I could play video games again, I got mixed answers to whether amdgpu or radeon would work with my card. According to the Arch Wiki, it looks like amdgpu only works "experimentally" on this card, so it kind-of-is-kind-of-isn't supported I suppose (https://wiki.archlinux.org/index.php/AMDGPU#Enable_amdgpu_for_Sea_Islands_Cards).

Anyways, I'm glad to have gotten it working. Thank you both for the help!

Fixed in #2211

magnumripper commented 8 years ago

The (benign) warning about cl_amd_media_ops should be gone after 6a63375

magnumripper commented 8 years ago

Not sure what do do with the inline issue. I think you should report it to MESA as a bug. Some OpenCL drivers require either static or inline for non-kernel OpenCL functions while others only support inline or nothing. So to be compatible with all of them we always use inline.

OTOH we could get away with something like

#ifndef MESA
inline
#endif
void S2KItSaltedSHA1Generator(...)

I can't remember if we have something like that available. I'll check it out.

magnumripper commented 8 years ago

Found it, __MESA__ can be used. I committed a workaround in 6c60b8f. @clinew can you build and run without any manual edits after that?

Oh, we didn't get the __MESA__ macro because they now write it as Mesa while we were checking only for MESA... Please try 9f8e940.

clinew commented 8 years ago

I ran 9f8e940 but it didn't build. Using printf showed me that the string being used was in fact Clover, not Mesa, so I made the following change:

clinew commented 8 years ago

Regarding MESA, it looks like someone else has run the "unsupported call" issue before but didn't narrow it down to the inline declaration (see: https://bugs.freedesktop.org/show_bug.cgi?id=87071); I've updated the issue with what's been found and mentioned that a workaround exists.

magnumripper commented 8 years ago

radeon: The kernel rejected CS, see dmesg for more information.

Can you post the corresponding info from dmesg, please?

clinew commented 8 years ago

The dmesg output is the same as what I posed earlier. I could get another copy if you really want.

Also, I was able build 22ad196 without errors.

magnumripper commented 8 years ago

You mean the crash backtraces? The "kernel rejected CS, see dmesg" message had me thinking there was some other info now.

clinew commented 8 years ago

Oh, no there isn't any new info, sorry. The program originally errored with many lines of kernel rejected CS, see dmesg and then the long dmesg backtrace that I originally posted. I didn't post the program outpost at first because the crash brought down the entire X window system, taking the ptty with it.

magnumripper commented 8 years ago

So if you peg GWS low enough it works fine, but not if you let it autotune? What if you manually make this change, does it work better?

That manual change seems to have worked. Presumably this is related to the waning in README-OPENCL about AMD drivers crashing after repeated runs from durations as short as 200ms. The log is as follows:

I'm just not sure we want to lower our default that much though. Ideally the kernel should be re-written and this problem will go away.

Come to think of it, there's an option Global_MaxDuration = 200 in john.conf, commented out by default. I think that will have the same effect without modifying source and recompiling. And even better, it will affect all formats. So you might want to uncomment that one.

NOTE though that I just verified that this functionality still worked, and it had bugged out. Fixed now, (2a71bfb) so you need latest code.

clinew commented 8 years ago

That also worked for me (on 2a71bfb).
