Since the script running is a failure condition, we should fail the
build properly, not leaving it up to the missing output to determine
that the build went wrong. This should partly address #38952 — nix
build will print out the build log on non-zero exits.
Also fix numberous bugs, such as:
- Not getting confused on more flags taking file arguments.
- Ensuring children reexport their children, but the original
binary/library doesn't.
- Not spawning children when it turns out we just dynamically link
under the threshold but our total number of inputs exceeeds it.
- Children were always named `libunnamed-*`, when that name was
supposed to be the last resort only.
ld-wrapper's own RPATH check hardcodes `.so`, but darwin uses `.dylib`
*and* (in practice due to lousy build systems) `.so`. We don't care
however because we never inject `--rpath` like that in practice on
Darwin. Hopefully someday we won't on linux either.
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/asgiref/default.nix
pkgs/development/python-modules/daphne/default.nix
pkgs/os-specific/linux/systemd/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.
