This introduces a dependency on xxHash. Unfortunately, hashcat's
build system wants to rebuild xxHash from the source code located
in <hashcat source root>/deps/git/xxHash, a Git submodule whose
contents are not included in the source tarball we currently
download.

This could be fixed by either using a recursive git clone instead
a tarball download, or patching the build files to use an existing
installation of xxHash (i.e. the one already provided by Nix). I
believe the latter is preferable since it avoids the situation in
which the xxHash version used by hashcat is different to the xxHash
version used by all other Nix packages.

Fortunately, this situation has been greatly improved since
release 5.0.0; the next release of hashcat should drop usage of
git submodules and provide better support for using existing
installations of dependencies.

Motivation for this change
Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
    • Increase by 607 kB
  • Fits CONTRIBUTING.md.

No attempt on x86_64-darwin (full log)

The following builds were skipped because they don't evaluate on x86_64-darwin: hashcat

Partial log (click to expand)


a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowUnsupportedSystem = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowUnsupportedSystem = true; }
to ~/.config/nixpkgs/config.nix.
