Package: beignet-opencl-icd
Version: 1.2.1-1+b1
Severity: important
Hello.
Every application that uses OpenCL crashes in this way:
$ clinfo
X server found. dri2 connection failed!
/dev/dri/card0 not authenticated
: CommandLine Error: Option 'enable-value-profiling' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Uninstalling this package fixes every application.
Installing the version in Sid 1.3.0-1 also crashes in the same way.
Running as root it crashes like this (with 1.3.0-1):
# clinfo
X server found. dri2 connection failed!
DRM_IOCTL_I915_GEM_APERTURE failed: Invalid argument
Assuming 131072kB available aperture size.
May lead to reduced performance or incorrect rendering.
get chip id failed: -1 [22]
param: 4, val: 0
: CommandLine Error: Option 'enable-value-profiling' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
I know that under KVM I don't need this package, but I will run this same Linux in different PCs,
some Intel, some AMD, some virtualized.
The expected behaviour is that it would not load and use another ICD instead, without crashing.
Thanks!!!

Control: retitle -1 beignet+mesa-opencl-icd crash if installed together
The lack of hardware isn't the trigger - having beignet-opencl-icd and
mesa-opencl-icd installed at the same time is. (beignet+pocl or
mesa+pocl is OK.)
Looks like some kind of "seeing the other ICD's copy of libllvm instead
of their own" problem (similar to
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=768185 , and possibly
appearing now because beignet just switched to the same LLVM version as
mesa), but I haven't yet had time to confirm this.

This bug goes away on rebuilding beignet with LLVM 3.8 (but that isn't a
good solution as it can trigger #848368, and also disables some of
beignet's functionality).
Debug backtraces show mesa-opencl-icd being loaded first, and the crash
happening when beignet-opencl-icd is loaded, suggesting one is jumping
to the other's LLVM globals (similar to #768185).
However, beignet still has the -Bsymbolic that fixed #768185 on all its
libraries, and while mesa-opencl-icd doesn't, adding it (via the obvious
patch to src/gallium/targets/opencl/Makefile.am) doesn't help.
(The missing parameters/locals in the LLVM parts of the traces are
probably #851371; because of this, I was unable to do the
is-this-the-same-pointer check from #768185)

good solution as it can trigger #848368, and also disables some of
beignet's functionality).
Debug backtraces show mesa-opencl-icd being loaded first, and the crash
happening when beignet-opencl-icd is loaded, suggesting one is jumping
to the other's LLVM globals (similar to #768185).
However, beignet still has the -Bsymbolic that fixed #768185 on all its
libraries, and while mesa-opencl-icd doesn't, adding it (via the obvious
patch to src/gallium/targets/opencl/Makefile.am) doesn't help.
(The missing parameters/locals in the LLVM parts of the traces are
probably #851371; because of this, I was unable to do the
is-this-the-same-pointer check from #768185)

All OpenCL ICDs with shared LLVM are useless if they can't be used
in real programs, so my opinion for whats its worth is that they link
statically with LLVM until the issue is resolved in another way allowing
shared LLVM (probably Stretch+1 material).
Of course this is just my opinion... but, please think about it.
Thanks A LOT!!!

Dear security team,
we plan to switch the OpenCL ICD beignet (and perhaps other ICDs if
neccessary) to link statically instead of dynamically against LLVM, to
work around #852746.
Currently OpenCL applications crash if both mesa-opencl-icd and
beignet-opencl-icd are installed - both link dynamically against LLVM
and are stepping somehow on each others toes. This makes OpenCL ICDs
pretty useless if the idea of having several of them installed does not
work (all available ICDs will be loaded by the application and queried
for available platforms/devices, thereafter the application can decide
which one to use).

The underlying issue is being investigated further, but I do not expect
a solution to be available for stretch.
I hope the security team agrees with this this workaround.
Since you want to keep track of statically linked packages:
For stretch src:beignet will be linked statically against
src:llvm-toolchain-3.9

Control: tags -1 - patch
Control: tags -1 upstream
Control: reassign -1 libllvm3.9
The real bug here is that libllvm is a shared library with global state,
and that loading it twice from the same application (the process of
checking which OpenCL driver works on the available hardware involves
loading all drivers) hence doesn't work.
beignet-opencl-icd is now statically linked against libllvm to work
around this bug, but I don't know whether anything else is affected.

Hi, I am unsure which bug report is correct for this as there is similar one #898033 and #954849 but I could confirm the problem is back since approximately May 2020 up to today:
