Simplify the management of the kernel parameter crashkernel
Currently, kexec-tools only updates the crashkernel to a new default
value only when both two conditions are met,
- auto_reset_crashkernel=yes in kdump.conf
- existing kernels or current running kernel should use the old default
value.
To address seen corner cases, the logic to tell if the second condition
is met becomes quite complex. Instead of making the logic more complex
to support aarch64-64k, this patch drops the second condition to
simplify the management of the crashkernel kernel parameter.
Another change brought by this simplification is kexec-tools will also
set up the kernel crashkernel parameter for a fresh install (previously
it's limited to osbuild).
Note
1. This patch also stop trying to update /etc/default/grub because
a) it only affects the static file /boot/grub2/grub.cfg
b) grubby is recommended to change the kernel command-line parameters
for both Fedora [1] and RHEL9 [2][3]
c) For the cases of aarch64 and POWER, different kernels could have
different default crashkernel value.
2. Starting with Fedora 37, posttrans rpm scriplet distinguish between
package install and upgrade.

kdumpctl: Add basic UKI support
A Unified Kernel Image (UKI) is a single EFI PE executable combining an
EFI stub, a kernel image, an initrd image, and the kernel command line.
They are defined in the Boot Loader Specification [1] as type #2
entries. UKIs have the advantage that all code as well as meta data that
is required to boot the system, not only the kernel image, is combined
in a single PE file and can be signed for EFI SecureBoot. This extends
the coverage of SecureBoot extensively.
For RHEL support for UKI were included into kernel-ark with 16c7e3ee836e
("redhat: Add sub-RPM with a EFI unified kernel image for virtual
machines").
There are two problems with UKIs from the kdump point of view at the
moment. First, they cannot be directly loaded via kexec_file_load and
second, the initrd included isn't suitable for kdump. In order to enable
kdump on systems with UKIs build the kdump initrd as usual and extract
the kernel image before loading the crash kernel.

Don't try to update crashkernel when bootloader is not installed
Currently when using anaconda to install the OS, the following errors
occur,
INF packaging: Configuring (running scriptlet for): kernel-core-5.14.0-70.el9.x86_64 ...
INF dnf.rpm: grep: /boot/grub2/grubenv: No such file or directory

INF dnf.rpm: grep: /boot/grub2/grubenv: No such file or directory
grep: /boot/grub2/grubenv: No such file or directory
grep: /boot/grub2/grubenv: No such file or directory
Or for s390, the following errors occur,
INF packaging: Configuring (running scriptlet for): kernel-core-5.14.0-71.el9.s390x ...
03:37:51,232 INF dnf.rpm: grep: /etc/zipl.conf: No such file or directory

INF packaging: Configuring (running scriptlet for): kexec-tools-2.0.23-9_1.el9_0.s390x ...
INF dnf.rpm: grep: /etc/zipl.conf: No such file or directory
This is because when anaconda installs the packages, bootloader hasn't
been installed and /boot/grub2/grubenv or /etc/zipl.conf doesn't exist.
So don't try to update crashkernel when bootloader isn't ready to avoid
the above errors.
Note this is the second attempt to fix this issue. Previously a file
/tmp/kexec_tools_package_install was created to avoid running the
related code thus to avoid the above errors but unfortunately that
approach has two issues a) somehow osbuild doesn't delete it for RHEL b)
this file could still exist if users manually remove kexec-tools.

Restricting kexec tool to allocate hole for kexec segments below 768MB
may not be relavent now since first memory block size can be 1024MB and
more.
Removing rma_top restriction will give more space to find holes for
kexec segments and existing in-place checks make sure that kexec segment
allocation doesn't cross the first memory block because every kexec segment
has to be within first memory block for kdump kernel to boot properly.

This commit has the same motivation as the commit 677da8a "sysconfig:

At present, only the kdump.conf generated for s390x has a slight
difference from the other arches, where the core_collector asks the
makedumpfile to use "-c" option to compress dump data by each page using
zlib, which is more efficient than lzo on s390x.

Date: Sat Oct 8 12:09:08 2022 +0800
Seperate dracut and dracut-squash compressor for zstd
Previously kexec-tools will pass "--compress zstd" to dracut. It
will make dracut to decide whether: a) call mksquashfs to make a
zstd format squash-root.img, b) call cmd zstd to make a initramfs.
Since dracut(>= 057) has decoupled the compressor for dracut and
dracut-squash, So in this patch, we will pass the compressor seperately.
Note:
The is_squash_available && !dracut_has_option --squash-compressor
&& !is_zsdt_command_available case is left unprocessed on purpose.
Actually, the situation when we want to call zstd compression is:
1) If squash function OK, we want dracut to invoke mksquashfs to make
a zstd format squash-root.img within initramfs.
2) If squash function is not OK, and cmd zstd presents, we want dracut
to invoke cmd zstd to make a zstd format initramfs.
is_zstd_command_available check can handle case 2 completely.
However, for the is_squash_available check, it cannot handle case 1
completely. It only checks if the kernel supports squashfs, it doesn't
check whether the squash module has been added by dracut when making
initramfs. In fact, in kexec-tools we are unable to do the check,
there are multiple ways to forbit dracut to load a module, such as
"dracut -o module" and "omit_dracutmodules in dracut.conf".
When squash dracut module is omitted, is_squash_available check will
still pass, so "--compress zstd" will be appended to dracut cmdline,
and it will call cmd zstd to do the compression. However cmd zstd may
not exist, so it fails.
The previous "--compress zstd" is ambiguous, after the intro of
"--squash-compressor", "--squash-compressor" only effect for
mksquashfs and "--compress" only effect for specific cmd.
So for the is_squash_available && !dracut_has_option
--squash-compressor && !is_zsdt_command_available case, we just leave
it to be handled the default way.

Allow to update kexec-tools using virt-customize for cloud base image
Resolves: bz2089871
Currently, kexec-tools can't be updated using virt-customize because
older version of kdumpctl can't acquire instance lock for the
get-default-crashkernel subcommand. The reason is /var/lock is linked to
/run/lock which however doesn't exist in the case of virt-customize.
This patch fixes this problem by using /tmp/kdump.lock as the lock
file if /run/lock doesn't exist.
Note
1. The lock file is now created in /run/lock instead of /var/run/lock since
Fedora has adopted adopted /run [2] since F15.
2. %pre scriptlet now always return success since package update won't
be blocked
