@globin I think this should be reverted. There is already a way to implement the required task without changing nixpkgs. If we really want this change to be merged, we should apply it to all the kernels in nixpkgs, not only this one.

It looks like this code was designed to use argsOverride to do what you are doing, not args directly.
In this case, your override should look like
pkg.override ({
argsOverride = {
modDirVersion="4.9.60+";
src=pkgs.lib.cleanSource /home/teto/mptcp;
};
})Now, this may not be the most obvious way to do it. However, I would prefer to keep this consistent with the other kernel implementations.

I saw the args.argsOverride afterwards. Any technical reason for args.argsOverride or is it legacy ? seeing that there is no specific documentation for kernels, people are bound to look at the nix code either way or use override out of habit.
Btw I would be interested in your opinon over #31463 :)

Really no idea... You could get more info by blame'ing on original kernels.

well so far it works but I had lots of trouble compiling the kernel for many reasons; i'll try to send some doc for the manual.
I needed to override some parameters because of an error I had:
"Error: modDirVersion specified in the Nix expression is wrong, it should be: 4.9.60+"
but the following override would not be taken into account
pkg.override ({
modDirVersion="4.9.60+";
src=pkgs.lib.cleanSource /home/teto/mptcp;
})
because the override would be overriden by the nixpkgs parameters
because of concatenation order:

argsOverride were introduced in 31fa2cd (NixOS#1654). It seems simpler to just override the default values with the attrs themselves. It also makes it more intuitive to use. (See NixOS#31596).
