Pull request #38470 added support for running/building kernels without
modules. This got merged in 38e04bbf29 but
unfortunately while this works perfectly on kernels without modules it
also makes sure that *every* kernel gets no modules.
So all of our VM tests fail since that merge with something like this:
machine# loading module loop...
machine# modprobe: FATAL: Module loop not found in directory /lib/modules/4.14.33
machine# loading module vfat...
machine# modprobe: FATAL: Module vfat not found in directory /lib/modules/4.14.33
machine# loading module nls_cp437...
machine# modprobe: FATAL: Module nls_cp437 not found in directory /lib/modules/4.14.33
machine# loading module nls_iso8859-1...
machine# modprobe: FATAL: Module nls_iso8859-1 not found in directory /lib/modules/4.14.33
machine# loading module fuse...
machine# modprobe: FATAL: Module fuse not found in directory /lib/modules/4.14.33
machine# loading module dm_mod...
machine# modprobe: FATAL: Module dm_mod not found in directory /lib/modules/4.14.33
I shortly tested this against the "misc" VM test and the test is working
again.
In the long term (and I currently don't have time for this) it would be
better to also have a VM test which tests a kernel without modules.

This is necessary due to a e2fsprogs update
(e6114781b0fad5345a2430fac3587d618273bda2) that causes mke2fs to
enable a feature (metadata_csum) that depends on crc32c.

Setting the hash to null is a convenient way to bypass the hash check
while developing. It looks like the ability to do this was inadvertently
removed while adding vendor directory support.
This still checks that the user is explicitly setting the value but
allows null as a valid option.
This is to go to a reproducible image build.
Note without this options image are identical from the Docker point of
view but generated docker archives could have different hashes.
This is to improve image creation reproducibility. Since the nar
format doesn't support hard link, the tar stream of a layer can be
different if a dependency of a layer has been built locally or if it
has been fetched from a binary cache.
If the dependency has been build locally, it can contain hard links
which are encoded in the tar stream. If the dependency has been
fetched from a binary cache, the tar stream doesn't contain any hard
link. So even if the content is the same, tar streams are different.
Resolved the following conflicts (by carefully applying patches from the both
branches since the fork point):
pkgs/development/libraries/epoxy/default.nix
pkgs/development/libraries/gtk+/3.x.nix

pkgs/development/python-modules/daphne/default.nix

Per @Ericson2314's suggestion [1], make it more clear that the active
hardenings are decided via whitelist; the blacklist is merely for the
debug messages.

Existing "mips64el" should be "mipsel".
This is just the barest minimum so that nixpkgs can recognize them as
systems - although required for building individual derivations onto
MIPS boards, it is not sufficient if you want to actually build nixos on
those targets
Previously, cargoUpdateHook was meaningful as it was used
in
[`cargo-fetch-deps`](19d3cf81d3/pkgs/build-support/rust/fetch-cargo-deps (L71)).
However, this entire file was removed in
5f8cf0048e. As far as I can
tell, nothing in the code is using it, but it is still
being passed around:
https://github.com/NixOS/nixpkgs/search?q=cargoUpdateHook&type=Code&utf8=%E2%9C%93
There are, however, legitimate use cases for it. For example,
in some software, some dependencies are not locked in Cargo.toml
and this causes Cargo to try fetching another version of them.
This doesn't work well with vendoring crates.
This hook allows to inject patching or whatever necessary workarounds
in the crate vendoring process. I suppose that's what it was for
in there in the first place.
This patch restores this hook and makes it usable again.
Before the code would fail silently for zero values and with some output for
empties. We now currently handle both via defaulting value to zero and making
`let` return success error code when there's no syntax error.
A separate function for building Bazel-bazed packages. Internally it splits the
build into two phases, fetching and building.
Users are expected to provide `fetchArgs.sha256` -- checksum of fetched
dependencies. Local dependencies should be removed in `fetchArgs.preInstall`.
Overall `fetchArgs` and `buildArgs` can be used to add specific steps to fetch
and build.
`find -executable` finds everything with the executable bit set,
including directories. Thats not harmful in this scenario as `cp` won't
copy those directories, but it does result in a few warning messages.
I originally wrote this for packaging proprietary games in Vuizvui[1]
but I thought it would be generally useful as we have a fair amount of
proprietary software lurking around in nixpkgs, which are a bit tedious
to maintain, especially when the library dependencies change after an
update.
So this setup hook searches for all ELF executables and libraries in the
resulting output paths after install phase and uses patchelf to set the
RPATH and interpreter according to what dependencies are available
inside the builder.
For example consider something like this:
stdenv.mkDerivation {
...
nativeBuildInputs = [ autoPatchelfHook ];
buildInputs = [ mesa zlib ];
...
}
Whenever for example an executable requires mesa or zlib, the RPATH will
automatically be set to the lib dir of the corresponding dependency.
If the library dependency is required at runtime, an attribute called
runtimeDependencies can be used to list dependencies that are added to
all executables that are discovered unconditionally.
Beside this, it also makes initial packaging of proprietary software
easier, because one no longer has to manually figure out the
dependencies in the first place.
