nikstur ab4e90c331 tests: correctly test appending secret to initrd
The way the test was implemented previously did not make it fail if no
secret was appended to the initrd. Now it is implemented similary to the
initrd-secrets test in Nixpkgs and works correctly.

Make File Installation Order Deterministic
2023-02-25 21:25:23 +01:00
Julian Stecklina cbccd64c57 tool: make file installation deterministic
Due to the use of hash maps, the order of file installation was not
deterministic. I've changed the code the use BTreeMaps instead, which
makes this deterministic. While I was here, I tried to simplify the
code a bit.

nikstur 75a19cd818 tool: correctly sort generation links
To correctly overwrite existing initrd with newer secrets (from newer
generations), the links need to be sorted from oldest generation to
newest.

nikstur 362205c2ec tool: check file hashes before copying
To minimize writes to the ESP but still find necessary changes, compare
the hashes of the files on the ESP with the "expected" hashes. Only copy
and overwrite already existing files if the hashes don't match. This
ensures a working-as-expected state on the ESP as opposed to previously
where already existing files were just ignored.

nikstur 3a3ad7c40d tool: write all generation artifacts at once
Previously, generations were installed one after another. Now all
artifacts (kernels, initrd etc.) are first collected and then installed.
This way the writes to the ESP are reduced as duplicate paths are
already removed in the collection phase.

nikstur df6b1b07f7 tool: use random names for secure tempfiles
Using random names for tempfiles makes handling them easier. It reduces
the amount of noise in the code because no custom name needs to be
provided for each tempfile. The names were not really useful in any
case.

It also does not burden the developer with ensuring uniqueness of names.
This is relevant when files for multiple generations need to be stored
in the same directory (e.g. because they need to be accessed after
handling one generation).

Out of an abundance of caution, 32 random alphanumeric characters are
chosen for each filename. The tempfile crate, in comparison, only
chooses 8. 32 characters should be enough to avoid collisions, even
if the PRNG is not of cryptographic quality.

nikstur a8d9ea128d tool: improve sd-boot generation display name
Leverage the bootspec `label` field in its intended way. The VERSION_ID
of the os-release in the stub now only contains the generation number
and the build time. This makes a correct PRETTY_NAME entirely dependent
on correct information in the bootspec `label` field.

nikstur 06f921ead0 tool: read build time from symlink
Read the build time from generation symlinks in /nix/var/nix/profiles
instead of from the underlying derivation. The derivation build time
will always be a UNIX epoch of 0 because of the `nix-build` sandbox,
which is useless for identifying when a generation was created.

Prevent loading of untrusted initrds

Alois Wohlschlager 081714cab9
Pass the built-in cmdline to the kernel
Do not pass our own cmdline on to the kernel. It may have been set by a
malicious boot loader specification entry, and could instruct the
kernel to load an arbitrary unprotected initrd (or perform some other
fun stuff). Instead, always pass the command line built into the UKI,
which is properly authenticated.
