5b31b099ae 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.

c8643af270 mkdumprd: add --aggressive-strip as default dracut args
The new aggressive strip option was added in dracut 058, which tell
dracut to build the initramfs stripping more sections of the ELF
binaries (basically strip .symtab, .strtab).

These section are only useful for debugging runtime failures, but in
kdump kernel, neccessary tools for debug any runtime failure are
absent, there is no point keeping these sections.

Stripping these section can help save some memory with almost no side
effect. So let enable --aggressive-strip by default.

Comparison of unpacked initramfs before / after enabling aggressive strip:

du -hs image image.aggressive-strip
31M     image
29M     image.aggressive-strip

ea7be0608e 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.

0ff44ca6e8 kdumpctl: fix is_dracut_mod_omitted
The function is pretty broken right now. To start with the -o/--omit
option allows a quoted, space separated list of modules. But using 'set'
breaks quotation and thus only considers the first element in the list.
Furthermore dracut uses getopt internally. This means that it is also
possible to pass the list via --omit=.

Fix the function by making use of getopt for parsing the dracut_args.
While at it also add a test cases to cover the functions.

f4c04c3d63 makedumpfile: Fix wrong exclusion of slab pages on Linux 6.2-rc1
Resolves: bz2155754
Upstream: https://github.com/makedumpfile/makedumpfile
Conflict: None

commit 5f17bdd2128998a3eeeb4521d136a192222fadb6
Author: Kazuhito Hagio <k-hagio-ab@nec.com>
Date:   Wed Dec 21 11:06:39 2022 +0900

    [PATCH] Fix wrong exclusion of slab pages on Linux 6.2-rc1

    * Required for kernel 6.2

    Kernel commit 130d4df57390 ("mm/sl[au]b: rearrange struct slab fields to
    allow larger rcu_head"), which is contained in Linux 6.2-rc1 and later,
    made the offset of slab.slabs equal to page.mapping's one.  As a result,
    "makedumpfile -d 8", which should exclude user data, excludes some slab
    pages wrongly because isAnon() returns true when slab.slabs is an odd
    number.  With such dumpfiles, crash can fail to start session with an
    error like this:

      # crash vmlinux dumpfile
      ...
      crash: page excluded: kernel virtual address: ffff8fa047ac2fe8 type: "xa_node shift"

    Make isAnon() check that the page is not slab to fix this.

5951b5e268 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

    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 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.

787b041aab kdump.conf: use a simple generator script to maintain
This commit has the same motivation as the commit 677da8a "sysconfig:
use a simple generator script to maintain".

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.

fc1c79ffd2 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.

677da8a59b sysconfig: use a simple generator script to maintain
These kdump.sysconfig.* files are almost identical with a bit difference
in several parameters, just use a simple script to generate them upon
packaging. This should make it easier to maintain, updating a comment or
param for a certain arch can be done in one place.

There are only some comment or empty option differences with the generated
version because some arch's sysconfig is not up-to-dated, this actually
fixes the issue, I used the following script to check these differences:

 # for arch in aarch64 i386 ppc64 ppc64le s390x x86_64; do
   ./gen-kdump-sysconfig.sh $arch > kdump.sysconfig.$arch.new
   git checkout HEAD^ kdump.sysconfig.$arch &>/dev/null

da0ca0d205 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

311b5b100b update kernel crashkernel in posttrans RPM scriptlet when updating kexec-tools
When doing in-place upgrading using leapp on x86_64, kdumpcl can't
acquire instance lock when running in %post RPM scriplet on x86_64,
  localhost upgrade[1306]: /bin/kdumpctl: line 49: /var/lock/kdump: No such file or directory
  localhost upgrade[1306]: kdump: Create file lock failed

and running "touch /var/lock/dkump" also fails with
"No such file or directory". Thus kdumpctl can't be run in %post
scriptlet. But kdumpctl can be run in %posttrans RPM scriplet.

Besides, it's better to update crashkernel after the kernel has been
updated. So let's update kernel crashkernel in the %posttrans
scriptlet which will be run in the end of a transaction i.e. after
the kernel has been updated.

Note for %posttrans scriptlet, "$1 == 1" means both installing a new
package and upgrading a package.

ca5a33855f s390: handle R_390_PLT32DBL reloc entries in machine_apply_elf_rel()
Resolves: bz2025860
Upstream: git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git

commit 186e7b0752d8fce1618fa37519671c834c46340e
Author: Alexander Egorenkov <egorenar@linux.ibm.com>
Date:   Wed Dec 15 18:48:53 2021 +0100

    s390: handle R_390_PLT32DBL reloc entries in machine_apply_elf_rel()

    Starting with gcc 11.3, the C compiler will generate PLT-relative function
    calls even if they are local and do not require it. Later on during linking,
    the linker will replace all PLT-relative calls to local functions with
    PC-relative ones. Unfortunately, the purgatory code of kexec/kdump is
    not being linked as a regular executable or shared library would have been,
    and therefore, all PLT-relative addresses remain in the generated purgatory
    object code unresolved. This in turn lets kexec-tools fail with
    "Unknown rela relocation: 0x14 0x73c0901c" for such relocation types.

    Furthermore, the clang C compiler has always behaved like described above
    and this commit should fix the purgatory code built with the latter.

    Because the purgatory code is no regular executable or shared library,
    contains only calls to local functions and has no PLT, all R_390_PLT32DBL
    relocation entries can be resolved just like a R_390_PC32DBL one.

0311f6e25b Set zstd as the default compression method for kdump initrd
zstd has better compression ratio and time consumption balance.
When no customized compression method specified in kdump.conf,
we will use zstd as the default compression method.

**The test method:

I installed kexec-tools with and without the patch, executing the following
command for 4 times, and calculate the averange time:

$ rm -f /boot/initramfs-*kdump.img && time kdumpctl rebuild && \
  ls -ail /boot/initramfs-*kdump.img

**discussion

zstd has a better compression ratio and time consumption balance.

v1 -> v2:
Use kdump_get_conf_val() to get dracut_args values of kdump.conf

v2 -> v3:
Attached testing benchmark

v3 -> v4:
Re-measured and re-attached the testing benchmark of x86_64 and ppc64le.
Changed regex '.*[[:space:]]' to '(^|[[:space:]])'

v4 -> v5:
Attacked lzo/xz/lz4 testing benchmark.

v5 -> v6:
Add zstd as required in kexec-tools.spec

Hello Coiby, you may use "RELEASE=34 make test-run", for
CONFIG_RD_ZSTD is enabled since fc-cloud-34

0adb0f4a8c 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.

f0892eeceb kdump/ppc64: suppress the error message "Could not find a registered notification tool" from servicelog_notify
When kexec-tools is newly installed, kdump migration action hasn't
registered and the following error could occur,
  INF dnf.rpm: Could not find a registered notification tool with the specified command ('/usr/lib/kdump/kdump-migrate-action.sh').

"servicelog_notify --list" could list registered notification tools for
a command but it outputs the above error as well. So simply redirect the
error to /dev/null when running "servicelog_notify --remove".
