kdumpctl: Only returns immediately after an error occurs in check_*_modified
Currently is_system_modified will return immediately when check_*_modified
return a non-zero value, and the remaining checks will not be executed.
For example, if there is a fs-related error exists, and someone changes the
kdump.conf, check_files_modified will return 1 and is_system_modified will
return 1 immediately. This will cause kdumpctl to skip check_fs/drivers_modified,
kdump.service will rebuild the initrd and start successfully, however, any
errors should prevent kdump.service from starting.
This patch will cause check_*_modifed to continue running until an error occurs
or all execution ends.

powerpc: update kdumpctl to remove deletion of kernel signing key once loaded
Kernel signing key is deleted once kdump is loaded. This causes confusion in
debugging since key is no longer visible. Unless someone knows how
kdumpctl script works, it is difficult to find out how kdump could be
loaded when there is no key on .ima keyring.
Remove deletion of kernel signing key once loaded. And then to prevent
multiple loading of same key when kdump service is disabled/enabled, update
key description field as well.

Introduce a function to get reserved memory size
The size of the reserved memory in the functions show_reserved_mem,
check_crash_mem_reserved, and do_estimate are fetched from the sysfs
node `/sys/kernel/kexec_crash_size`. However, in the case of fadump,
the reserved area size is instead present in
/sys/kernel/fadump/mem_reserved.
For example:
$ kdumpctl showmem
kdump: Dump mode is fadump
kdump: Reserved 0MB memory for crash kernel
The above command showed 0MB for Reserved memory which is incorrect, the
actual reservation was 2048MB.
To resolve this issue a new helper function is introduced to fetch
reserved memory size based on the dump mode. For "fadump" mode,
it looks in `/sys/kernel/fadump/mem_reserved`, otherwise, it uses
`/sys/kernel/kexec_crash_size`. And all functions that previously
fetching reserved memory directly from `/sys/kernel/kexec_crash_size`
sysfs node are now updated to use this new function to get the reserved
memory size.
With the fix in place, the `kdumpctl showmem` command will now display
correct reserved memory size.
$ kdumpctl showmem
kdump: Dump mode is fadump
kdump: Reserved 2048MB memory for crash kernel

kdumpctl: merge check_current_{kdump,fadump}_status
Both functions are almost identical. The only differences are (1) the
sysfs node the status is read from and (2) the fact the fadump version
doesn't verify if the file it's trying to read actually exists. Thus
merge the two functions and get rid of the check_current_status wrapper.
While at it rename the function to is_kernel_loaded which explains
better what the function does.
Finally, after moving FADUMP_REGISTER_SYS_NODE shellcheck can no longer
access the definition and starts complaining about it not being quoted.
Thus quote all uses of FADUMP_REGISTER_SYS_NODE.

kdump-lib: add support for 64K aarch64
On aarch64, both 4K and 64K kernel can be installed, while they demand
different size reserved memory for kdump kernel.
'get_conf PAGE_SIZE' can not work if installing a 64K kernel when
running a 4K kernel. Hence resorting to the kernel release naming rules.
At present, the 64K kernel has the keyword '64k' in its suffix.
The base line for 64K is decided based on 4K. The diff 100M is picked up
since on a high end machine without smmu enabled, the diff of MemFree is
82M.
As for the smmu case, a huge difference in the memory consumption lies
between 64k and 4k driver. And it should be calculated separatedly.

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.

kdumpctl: lower the log level in reset_crashkernel_for_installed_kernel
Although upgrading the kernel with `rpm -Uvh` is not recommended, the

kernel through it.
```
kdump: kernel 5.14.0-80.el9.x86_64 doesn't exist
kdump: Couldn't find current running kernel
```
Not finding the currently running kernel will only make kdump unable to copy the
grub entry parameters to the newly installed kernel, so lower the log level.

Upstream: RHEL-only
After leapp upgrade from 8.8 to 9.2 on Azure, RHEL9 kernel has
crashkernel=auto. This happens because kexec-tools's posttrans scriptlet
is executed before kernel's posttrans scriptlet (which in turn runs the
kernel-install hooks). One of the kernel-install hook is responsible for
adding a new boot entry for the new kernel. So when kexec-tools's posttrans
scriptlet is running, RHEL9 kernel is yet to have a boot entry so
kexec-tools couldn't set up the crashkernel parameter. Later one
kernel-install hook makes RHEL9 kernel inherit crashkernel=auto.
Fix this issue by letting 92-crashkernel.install reset crashkernel=auto.

Don't try to update crashkernel when bootloader is not installed

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.

fadump: fix default initrd backup and restore logic
In case of fadump, default initrd is rebuilt with dump capturing
capability, as the same initrd is used for booting production kernel
as well as capture kernel.
The original initrd file is backed up with a checksum, to restore
it as the default initrd when fadump is disabled. As the checksum
file is not kernel version specific, switching between different
kernel versions and kdump/fadump dump mode breaks the default initrd
backup/restore logic. Fix this by having a kernel version specific
checksum file.
Also, if backing up initrd fails, retaining the checksum file isn't
useful. Remove it.

Choosing the most memory-consuming key slot when estimating the
memory requirement for LUKS-encrypted target
When there are multiple key slots, "kdumpctl estimate" uses the least
memory-consuming key slot. For example, when there are two memory slots

virtiofs support for kexec-tools
This patch add virtiofs support for kexec-tools by introducing a new option
for /etc/kdump.conf:
virtiofs myfs
Where myfs is a variable tag name specified in qemu cmdline
"-device vhost-user-fs-pci,tag=myfs".
The patch covers the following cases:
1) Dumping VM's vmcore to a virtiofs shared directory;
2) When the VM's rootfs is a virtiofs shared directory and dumping the
VM's vmcore to its subdirectory, such as /var/crash;
3) The combination of case 1 & 2: The VM's rootfs is a virtiofs shared
directory and dumping the VM's vmcore to another virtiofs shared
directory.
Case 2 & 3 need dracut >= 057, otherwise VM cannot boot from virtiofs
shared rootfs. But it is not the issue of kexec-tools.

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

address the case where there are multiple values for the same kernel arg
There is the case where there are multiple entries of the same parameter on
the command line, e.g.
GRUB_CMDLINE_LINUX="crashkernel=110M crashkernel=220M fadump=on crashkernel=330M".
In such an situation _update_kernel_cmdline_in_grub_etc_default only
updates/removes the last entry which is usually not what you want as the
kernel (for crashkernel) takes the last entry it can find.
Thus make sure the case with multiple entries of the same parameter is
handled properly by removing all occurrences of given parameter first.
Note
1. sed command group and conditional control has been used to get rid of
grep.
2. Fully supporting kernel cmdline as documented in
Documentation/admin-guide/kernel-parameters.rst is complex and in
foreseeable future a full implementation is not needed. So simply
document the unsupported cases instead.

Note that,
1. this patch also fixes a issue which is kdumpctl would try to reset
crashkernel even osbuild has provided custom crashkernel value.
2. kernel hook 92-crashkernel.install installed by kexec-tools is
guaranteed to be ran by kernel-install. kexec-tools doesn't recommend
kernel so there is no guarantee kernel is installed after kexec-tools.
But dnf invokes kernel-install in the posttrans scriptlet (of kernel-core)
which is always ran after all packages including kexec-tools and kernel

3. To be able to do unit tests, the logic of reading environment variable

set up kernel crashkernel for osbuild in kernel hook
osbuild is a tool to build OS images. It uses bwrap to install packages
inside a sandbox/container. Since the kernel package recommends
kexec-tools which in turn recommends grubby, the installation order would
be grubby -> kexec-tools -> kernel. So we can use the kernel hook
92-crashkernel.install provided by kexec-tools to set up kernel
crashkernel for the target OS image. But in osbuild's case, there is no
current running kernel and running `uname -r` in the container/sandbox
actually returns the host kernel release. To set up kernel crashkernel for
the OS image built by osbuild, a different logic is needed.
We will check if kernel hook is running inside the osbuild container
then set up kernel crashkernel only if osbuild hasn't specified a
custome value. osbuild exposes [1] the container=bwrap-osbuild environment
variable. According to [2], the environment variable is not inherited down
the process tree, so we need to check /proc/1/environ to detect this
environment variable to tell if the kernel hook is running inside a
bwrap-osbuild container. After that we need to know if osbuild wants to use
custom crashkernel value. This is done by checking if /etc/kernel/cmdline
has crashkernel set [3]. /etc/kernel/cmdline is written before packages
are installed.

reset kernel crashkernel for the special case where the kernel is updated right after kexec-tools
When kexec-tools updates the default crashkernel value, it will try to
reset the existing installed kernels including the currently running
kernel. So the running kernel could have different kernel cmdline
parameters from /proc/cmdline. When installing a kernel after updating
kexec-tools, /usr/lib/kernel/install.d/20-grub.install would be called
by kernel-install [1] which would use /proc/cmdline to set up new kernel's
cmdline. To address this special case, reset the new kernel's crashkernel
and fadump value to the value that would be used by running kernel after
rebooting by the installation hook. One side effect of this commit is it
would reset the installed kernel's crashkernel even currently running kernel
don't use the default crashkernel value after rebooting. But I think this
side effect is a benefit for the user.
The implementation depends on kernel-install which run the scripts in
/usr/lib/kernel/install.d passing the following arguments,
add KERNEL-VERSION $BOOT/MACHINE-ID/KERNEL-VERSION/ KERNEL-IMAGE [INITRD-FILE ...]
An concrete example is given as follows,
add 5.11.12-300.fc34.x86_64 /boot/e986846f63134c7295458cf36300ba5b/5.11.12-300.fc34.x86_64 /lib/modules/5.11.12-300.fc34.x86_64/vmlinuz
kernel-install could be started by the kernel package's RPM scriplet [2].
As mentioned in previous commit "try to reset kernel crashkernel when
kexec-tools updates the default crashkernel value", kdumpctl has difficulty
running in RPM scriptlet fore CoreOS. But rpm-ostree ignores all kernel hooks,
there is no need to disable the kernel hook for CoreOS/Atomic/Silverblue. But a
collaboration between rpm-ostree and kexec-tools is needed [3] to take care
of this special case.
Note the crashkernel.default support is dropped.

try to reset kernel crashkernel when kexec-tools updates the default crashkernel value
kexec-tools could update the default crashkernel value.
When auto_reset_crashkernel=yes, reset kernel to new crashkernel
value in the following two cases,
- crashkernel=auto is found in the kernel cmdline
- the kernel crashkernel was previously set by kexec-tools i.e.
the kernel is using old default crashkernel value
To tell if the user is using a custom value for the kernel crashkernel
or not, we assume the user would never use the default crashkernel value
as custom value. When kexec-tools gets updated,
1. save the default crashkernel value of the older package to
/tmp/crashkernel (for POWER system, /tmp/crashkernel_fadump is saved
as well).
2. If auto_reset_crashkernel=yes, iterate all installed kernels.
For each kernel, compare its crashkernel value with the old
default crashkernel and reset it if yes
The implementation makes use of two RPM scriptlets [2],
- %pre is run before a package is installed so we can use it to save
old default crashkernel value
- %post is run after a package installed so we can use it to try to reset
kernel crashkernel
There are several problems when running kdumpctl in the RPM scripts
for CoreOS/Atomic/Silverblue, for example, the lock can't be acquired by
kdumpctl, "rpm-ostree kargs" can't be run and etc.. So don't enable this
feature for CoreOS/Atomic/Silverblue.
Note latest shellcheck (0.8.0) gives false positives about the
associative array as of this commit. And Fedora's shellcheck is 0.7.2
and can't even correctly parse the shell code because of the associative
array.

rewrite reset_crashkernel to support fadump and to used by RPM scriptlet
Rewrite kdumpctl reset-crashkernel KERNEL_PATH as
kdumpctl reset-crashkernel [--fadump=[on|off|nocma]] [--kernel=path_to_kernel] [--reboot]
This interface would reset a specific kernel to the default crashkernel value
given the kernel path. And it also supports grubby's syntax so there are the
following special cases,
- if --kernel not specified,
- use KDUMP_KERNELVER if it's defined in /etc/sysconfig/kdump
- otherwise use current running kernel, i.e. `uname -r`
- if --kernel=DEFAULT, the default boot kernel is chosen
- if --kernel=ALL, all kernels would have its crashkernel reset to the
default value and the /etc/default/grub is updated as well
--fadump=[on|off|nocma] toggles fadump on/off for the kernel provided
in KERNEL_PATH. If --fadump is omitted, the dump mode is determined by
parsing the kernel command line for the kernel(s) to update.
CoreOS/Atomic/Silverblue needs to be treated as a special case because,
- "rpm-ostree kargs" is used to manage kernel command line parameters
so --kernel doesn't make sense and there is no need to find current
running kernel
- "rpm-ostree kargs" itself would prompt the user to reboot the system
after modify the kernel command line parameter
- POWER is not supported so we can assume the dump mode is always kdump
This interface will also be called by kexec-tools RPM scriptlets [1]
to reset crashkernel.
Note the support of crashkenrel.default is dropped.

add helper functions to get kernel path by kernel release and the path of current running kernel
grubby --info=kernel-path or --add-kernel=kernel-path accepts a kernel
path (e.g. /boot/vmlinuz-5.14.14-200.fc34.x86_64) instead of kernel release
(e.g 5.14.14-200.fc34.x86_64). So we need to know the kernel path given
a kernel release. Although for Fedora/RHEL, the kernel path is
"/boot/vmlinuz-<KERNEL_RELEASE>", a path kernel could also be
/boot/<machine-id>/<KERNEL_RELEASE>/vmlinuz. So the most reliable way to
find the kernel path given a kernel release is to use "grubby --info".
For osbuild, a kernel path may not yet exist but it's valid for
"grubby --update-kernel=KERNEL_PATH". For example, "grubby -info" may
output something as follows,
index=0
kernel="/var/cache/osbuild-worker/osbuild-store/tmp/tmp2prywdy5object/tree/boot/vmlinuz-5.15.10-100.fc34.x86_64"
args="ro no_timer_check net.ifnames=0 console=tty1 console=ttyS0,115200n8"
root="UUID=76a22bf4-f153-4541-b6c7-0332c0dfaeac"
initrd="/var/cache/osbuild-worker/osbuild-store/tmp/tmp2prywdy5object/tree/boot/initramfs-5.15.10-100.fc34.x86_64.img"
There is no need to check if path like
/var/cache/osbuild-worker/osbuild-store/tmp/tmp2prywdy5object/tree/boot/vmlinuz-5.15.10-100.fc34.x86_64
physically exists.
Note these helper functions doesn't support CoreOS/Atomic/Silverblue
since grubby isn't used by them.

provide kdumpctl get-default-crashkernel for kdump_anaconda_addon and RPM scriptlet
Provide "kdumpctl get-default-crashkernel" for kdump_anaconda_addon
so crashkernel.default isn't needed.
When fadump is on, kdump_anaconda_addon would need to specify the dump
mode, i.e. "kdumpctl get-default-crashkernel fadump".
This interface would also be used by RPM scriptlet [1] to fetch default
crashkernel value.

Conflict: The upstream commit was submitted before shfmt and .editorconfig.
So there are issues like 4 spaces verse tab indentation, double
brackets verse single bracket and etc.

kdumpctl: enable secure boot on ppc64le LPARs
On ppc64le LPAR, secure-boot is a little different from bare metal,
Where
host secure boot: /ibm,secure-boot/os-secureboot-enforcing DT property exists
while
guest secure boot: /ibm,secure-boot >= 2
Make kexec-tools adapt to LPAR
