We look for the root fs on the device of the booted ESP, and for the
other partitions on the device of the root fs. On EFI systems this
generally boils down to the same, but there are cases where this doesn't
hold, hence document this properly.
Fixes: #31199
To hash long files (like initrd) add the funcion
make_pcrlock_record_from_stream, that will read a long file (or stdin)
to generate the digests of multiple hashes, redading block by block.
Use this new function in verb_lock_raw and verb_lock_kernel_initrd.

This commit adds support for loading, measuring and handling a ".ucode"
UKI section. This section is functionally an initrd, intended for
microcode updates. As such it will always be passed to the kernel first.
Resolve at attach/detach/inspect time, so that the image is pinned and requires
re-attaching on update, given files are extracted from it so just passing
img.v/ to RootImage= is not enough to get a portable image updated
I was bitten several times by testing things only with --root flag, so this
commit prepares the existing test cases to run on / too. This required the test
cases to clean up after themselves, thus I have put each test case in a
separate subshell and used traps to do the cleanups.
I needed to change the hierarchy used by the test extension to /opt, because
unmounting /usr often failed with EBUSY.
CentOS/Fedora use annobin which will complain if FORTIFY_SOURCE=0
is used so we disable those checks to avoid the warnings.
We also make sure that when we query the compilation flags so we can
add more, we set _fortify_level=0 and undefine _lto_flags so that we
don't get those flags in the result.
Preexisting mutable directory is likely set by the admin, so we expect it to be
set up properly instead of changing the mode of the directory behind admin's
back.
The merged overlayfs filesystem mountpoint has a mode of its top layer. We have
been creating all the directories to be used as layers with mode 0700, so the
result was a merged hierarchy with such mode - it rendered the merged hierarchy
to be accesible only by root.
Change the mode of a directory serving as the top layer to match the hierarchy
to avoid such situations.
