[17.09] bcc tools segfault

[shosti]

(Possibly related to #17683, I don't know enough to know for sure.)

Issue description

BCC tools on my system (17.09 beta) segfault.

Steps to reproduce

1. In /etc/nixos/configuration.nix:

  environment.systemPackages = with pkgs; [
    ...
    linuxPackages.bcc
    ...
  ];

2. sudo biolatency (I also tried biotop, biosnoop, and zfsslower)

Output: https://gist.github.com/4ed1132ca201dcdb47a8ea7074b50265 (similar for all tools).

Technical details

• System: 17.09beta1199.a193400216 (Hummingbird)
• Nix version: nix-env (Nix) 1.11.15
• Nixpkgs version: "17.09beta1199.a193400216"
• Sandboxing enabled: false

Please try to install bcc by adding programs.bcc.enable = true; into your configuration.nix after updating to 44b6a15 .

[orivej]

Otherwise install bcc without updating by adding these changes to your configuration.nix:

    environment.systemPackages = [ config.boot.kernelPackages.bcc ];
    boot.extraModulePackages = [ config.boot.kernelPackages.bcc ];

@globin @Mic92 Maybe sysdig and bcc modules should be included in the 17.09 release?

[Mic92]

No objections from my side. In fact they are more documentation then code.

Thanks for the info! Unfortunately the problem seems to persist. I've been able to reproduce on a VM with a minimal configuration: https://gist.github.com/4f86dfedc913d437b2660e3145e51b62 (my current NixOS version is 17.09beta1314.dc4750b3c3). The problem seems to be the same with the 4.13 kernel and the default 4.9 kernel.

[Mic92]

Right. Looks like we are running into this problem: iovisor/bcc#1221

[Mic92]

If I build the program manually source and run it from the build directory it seems not the trigger the bug.
