No functional change, just preparation for later commits.
These can be used in kernel-install later.
Note, unlike the our usual coding style, the arguments for
boot_entry_token_ensure() and parse_boot_entry_token_type() are
referenced, updated, and may freed, hence, always pass initialized
values. That's why they are not named as 'ret_xyz'.
Define $KERNEL_INSTALL_UKI_GENERATOR in case one wants it to be different from $KERNEL_INSTALL_INITRD_GENERATOR. This can be useful if one wants to use mkinitcpio / Dracut to generate the initrd, but without creating the UKI so this can be left for e.g. ukify or something else. Right now these initrd generators will read /etc/kernel/install.conf and generate the UKI
'pos' is incremented after each assignment. If we use the maximum number
of arguments, we end up with pos==9 after all the assignments, and it
points to where the next value would be assigned. This position must remain
NULL.
The assert I "fixed" was intentionally introduced in
26abdc73a2 as a bugfix. So my "fix" repeated
the same error that was fixed back then.
I noticed that our coverage reports miss some files completely - this
happens when the test doesn't touch the code in them at all, so the
generated coverage data (and resulting reports) have no information
about them. Let's fix this by doing an initial zero coverage capture
that contains a zeroed counter for every instrumented line in every
file, so when we later merge it with a capture from the test, it shows up
with a missing coverage instead of not showing at all.
We need to expand the subshell expression during the `bash -c`
invocation, not before, to take the desired effect, as now it expands to:
timeout 30 bash -c 'while [[ 0 -eq 0 ]]; do sleep 1; done'
instead of the expected:
timeout 30 bash -c 'while [[ $(coredumpctl list -q --no-legend 770 | wc -l) -eq 0 ]]; do sleep 1; done'

This is not useful. Those are externally-provided files, and they are likely to
have entries which we know nothing about.
Fixup for d2ebd50d7f
and 6920049fad:
- add a comment that the last arg must be NULL and adjust the assert.
- move initialization around so that fields are declared,
initialized, and consumed in the same order.
- move declaration of pos adjacent do declaration of command_line.
This makes it easy to see that it was not initialized correctly.
- initialize buffers before writing the pointer into the args array.
This makes no difference for the compiler, but it just feels "wrong"
to do it in opposite order.
Because pos was off, we would ignore args after the timeout, and also
overwrite the buffer if enough args were used.
I think this is case shows clearly that declaring all variables at the
top of the function, with some initialized and other not, is very
error-prone. The compiler has no issue with declaring variables whereever,
and we should take advantage of this to make it keep declaration,
initialization, and use close. (Within reason of course.)
This is a little helper I used when preparing the tests for auxv
parsing. Just looking at hexdump output is pretty hard. We could
enhance it to display some specific data types better.
Chasing symlinks is a core function that's used in a lot of places
so it deservers a less verbose names so let's rename it to chase()
and chaseat().
We also slightly change the pattern used for the chaseat() helpers
so we get chase_and_openat() and similar.
It's a sycall group of our own definition, and the output is erroneous
to claim otherwise. Let's hide it.
This adds syscall_set_add() which is nicely symmetric to the existing
syscall_set_remove().
Follow-up for: 6d6a08547c
So far we asked via a comment that @default should stay the first group
and @known the last group in the list. Let's enforce that statically, in
code, too.
Let's group these 4 syscalls, as they offer similar things and I guess
might be used in conjunction quite often, as they offer unprivileged
sandboxing.
