Not only block subsystem, but also misc has device named "loop*", and
the test always said that the following device is newly found:
---
/* test_sd_device_enumerator_filter_subsystem */
New device found: subsystem:misc syspath:/sys/devices/virtual/misc/loop-control
1 new devices are found in re-scan
---
Profiling tools tend to work better when binaries and libraries
are compiled with frame pointers as without them there's no easy
and fast way to get the current stacktrace.
I reordered the component list to match chronological order: we first install
an entry, then boot it, then the checks happen, etc. Before it was
ordered by "importance", but that is harder to follow.
The boot-counting file-renaming entry-sorting part that the boot
loader implements is moved to the main document. The second document
describes a specific implementation that is provided through systemd
units.
The sorting algorithm is extended to say that bad entries should
be sorted later.
I also added a note that bad entries should be available for booting.
For some reason, the second document said that it applies only to EFI systems.
AFAIK there are no implementations for non-EFI, but the specification should
work just fine, if somebody were to implement it. So that part is dropped.
Fixes#23345.
Sadly, bootctl doesn't implement sorting of boot entries with counting :((((
But I'm leaving that for another PR.
Device paths are a packed data structure and the UEFI spec is clear that
members may be misaligned.
In this case all accesses are aligned except for the signature. We can
simply memcpy it instead of making a whole (aligned) copy of the device
path.
This drops the unused xnew0 and xallocate_zero_pool as there is only two
users of it. _cleanup_freepool_ will be phased out once the types in the
declarations are changed/renamed.
A future commit will add support for unicode collation protocol that
allows case folding and comparing strings with locale awareness. But it
only operates on whole strings, so fnmatch cannot use those without a
heavy cost. Instead we just case fold the patterns instead (the IDs we
try to match are already lower case).
https://github.com/systemd/systemd/pull/23192 caused breakage in
Arch Linux's build tooling. Let's give users an opt-out aside from
reverting the patch. It's hardly any maintenance work on our side
and gives users an easy way to revert the locale change if needed.
Of course, by default we still pick C.UTF-8 if the option is not
specified.
