Motivation for this change

usb_modeswitch currently isn't working #60878

This is unfortunately quite an extensive change, mostly redoing the packaging of usb-modeswitch itself. Because of the size of the change, I'd like a review from the nixpkgs packaging experts before attempting to upstream this. I have successfully tested this with an "LG L-02C LTE".

This has the following goals:

  1. Make DESTDIR and PREFIX work as per usual. Currently PREFIX isn't supported due to many hardcoded paths.

  2. Remove hardcoded paths to dependencies and rely on the PATH variable instead.

  3. Allow configuration of which init systems to use, instead of checking the state of the build machine.

Still TODO:

  • Fix kernel module probing

  • New default PREFIX changes the result of make install. Either change the readme, or restore the existing behavior.

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 nix-review --run "nix-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)
  • Assured whether relevant documentation is up to date
  • Fits CONTRIBUTING.md.

Sorry, something went wrong.

What do you mean by "Fix kernel module probing" ?

Answer from Matrix: "there's a section in the dispatcher that checks for potential kernel features by looking at /lib/modules/$(uname -r). this won't work as is, but I don't have a plan for how to fix it yet"

As I'm also suffering from broken usb-modeswitch and I have hardware to test this pull-request, I'm offering this review (per https://nixos.org/nixpkgs/manual/#reviewing-contributions-package-updates and https://nixos.org/nixpkgs/manual/#reviewing-contributions-module-updates). Note that this is a partial review as I can't follow all the changes that the patch file of brings.

Reviewed points (package update)
  • package name fits guidelines (no change)
  • package version fits guidelines (no change)
  • package build on x86_64-linux
  • executables tested on x86_64-linux
  • all depending packages build
Reviewed points (module update)
  • changes are backward compatible
  • removed options are declared with mkRemovedOptionModule (not applicable)
  • changes that are not backward compatible are documented in release notes (not applicable)
  • module tests succeed on ARCHITECTURE
  • options types are appropriate (no change)
  • options description is set (no change)
  • options example is provided (no change)
  • documentation affected by the changes is updated
Comments
  • I tested this module with a Huawei K3765: It works as expected (but didn't before applying this pull request)
    • A few seconds after plugging in the device, the system log told me that the usb modeswitching service is started.
    • Devices /dev/ttyUSB{0,1,2} appeared.
    • I used picocom and some AT-commands to query my provider's balance.
  • Tested after rebasing onto current nixos-unstable channel (bc94dcf).
  • For what it's worth: I expected ModemManager to pick up the device, but ModemManager didn't auto-start -- I had to start it manually with systemctl start ModemManager. This is possibly due to 3f9ac24 .
