dune's Issues
Integrate Nix
I need sudo to build dune. I tried adding sudo to default.nix under buildInputs, but I get an issue with the owner of sudo:
> nix-build default.nix
these derivations will be built:
/nix/store/pvn8p8y8kvvgfhlc4a1q0z75cpwq9dkh-dune-1.0.drv
building path(s) ‘/nix/store/lmv92mliamf24h5yvnynlqn1zw7a7q61-dune-1.0’
sudo: /nix/store/w9rs11zhvn6y4a0cs252qdnvqfr2zmp2-sudo-1.8.19p2/bin/sudo must be owned by uid 0 and have the setuid bit set
builder for ‘/nix/store/pvn8p8y8kvvgfhlc4a1q0z75cpwq9dkh-dune-1.0.drv’ failed with exit code 1
error: build of ‘/nix/store/pvn8p8y8kvvgfhlc4a1q0z75cpwq9dkh-dune-1.0.drv’ failed
Without sudo it fails to find it when calling builder.sh. I'm following this blog for creating my own Nix expressions.
OS breaking bug
Running programs under the sandbox which fork/exec a subprocess, where that child fails with some error seems to leave the process running at 100% CPU. Worst of all, this process becomes unkillabe even with kill -9. Only way to fix is it to restart the system, which may be difficult as the OS tries to wait for the processes to end gracefully before shutting down...
I don't think Dune handles signals properly? Or it's a bug with the kernel module?
Dune Bug when Processes Running Concurrently
Dune does not support running two processes in parallel. Part of the problem seems to be that the memory management is not thread safe, but even putting a big lock around the handler function for EPT violations is not enough.
The problem happens when running two concurrent dune processes, for example on two different terminals. The first process runs all the way, but when exiting, it attempts to destroy all virtual CPUs?
Here is the kernel log showing the problem:

For some reason, once process1 is done, process2 is killed off.
Monotinically Increasing time for CPU Instructions
Several instructions RDTSC, RDTSCP, RDPMC, RDRAND, and RDSEED, are currently trapped by the dune and handled in the hypervisor (dune kernel module code). There is a single kernel module dune process running in the kernel. Therefore, we cannot increment the value we return for this functions.
We need a way to track which process sent the request, then we could have a nice increasing deterministic counter.
The Oreilly Device Driver Book, chapter 2. talks about doing this. So there should be a way to find out which process did it:
The Current Process
Although kernel modules don’t execute sequentially as applications do, most actions
performed by the kernel are done on behalf of a specific process. Kernel code can
refer to the current process by accessing the global item current, defined in <asm/
current.h>, which yields a pointer to struct task_struct, defined by <linux/sched.h>.
The current pointer refers to the process that is currently executing. During the exe-
cution of a system call, such as open or read, the current process is the one that
invoked the call. Kernel code can use process-specific information by using current,
if it needs to do so. An example of this technique is presented in Chapter 6.
MMU Bug
There is something wrong with Dune and it's handling of EPT Violations.
Pbuilder currently fails to run under Dune to do chroot errors. However, for some reason this throws an error from the kernel.
This obviously should not happen. After this, Dune and the duned process are stuck and the computer must be shutdown.
(For some reason, I can't attach the file).
