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.

/usr/lib/udev/ccw_init [1] shipped by s390utils extracts the values of
SUBCHANNELS, NETTYPE and LAYER2 from /etc/sysconfig/network-scripts/ifcfg-*
or /etc/NetworkManager/system-connections/*.nmconnection to activate znet
network device. If the connection profile is copied to initrd,
there is no need to set up the "rd.znet" dracut cmdline parameter.
There are two cases addressed by this commit,
1. znet network interface is a slave of bonding/teaming/vlan/bridging
network. The connection profile has been copied to initrd by
kdump_copy_nmconnection_file and it contains the info needed by
ccw_init.
2. znet network interface is a slave of bonding/teaming/vlan/bridging
network. The corresponding ifcfg-*/*.nmconnection file may not contain
info like SUBCHANNELS [2]. In this case, copy the ifcfg-*/*.nmconnection
file that has this info to the kdump initrd. Also to prevent the copied
connection profile from being chosen by NM, set
connection.autoconnect=false for this connection profile.
With this implementation, there is also no need to check if znet is
used beforehand.
Note
1. ccw_init doesn't care if SUBCHANNELS, NETTYPE and LAYER2 comes from
an active NM profile or not. If an inactive NM profile contains this
info, it needs to be copied to the kdump initrd as well.
2. "rd.znet_ifname=$_netdev:${SUBCHANNELS}" is no longer needed needed
because now there is no renaming of s390x network interfaces when
reusing NetworkManager profiles. rd.znet_ifname was introduced in
commit ce0305d ("Add a new option 'rd.znet_ifname' in order to use it
in udev rules") to address the special case of non-persistent

A NIC may get a different name in the kdump kernel from 1st kernel
in cases like,
- kernel assigned network interface names are not persistent e.g. [1]
- there is an udev rule to rename the NIC in the 1st kernel but the
kdump initrd may not have that rule e.g. [2]
If NM tries to match a NIC with a connection profile based on NIC name
i.e. connection.interface-name, it will fail the above bases. A simple
solution is to ask NM to match a connection profile by MAC address.
Note we don't need to do this for user-created NICs like vlan, bridge and
bond.
An remaining issue is passing the name of a NIC via the kdumpnic dracut
command line parameter which requires passing ifname=<interface>:<MAC> to
have fixed NIC name. But we can simply drop this requirement. kdumpnic
is needed because kdump needs to get the IP by NIC name and use the IP
to created a dumping folder named "{IP}-{DATE}". We can simply pass the
IP to the kdump kernel directly via a new dracut command line parameter
kdumpip instead. In addition to the benefit of simplifying the code,
there are other three benefits brought by this approach,
- make use of whatever network to transfer the vmcore. Because as long
as we have the network to we don't care which NIC is active.
- if obtained IP in the kdump kernel is different from the one in the
1st kernel. "{IP}-{DATE}" would better tell where the dumped vmcore
comes from.
- without passing ifname=<interface>:<MAC> to kdump initrd, the
issue of there are two interfaces with the same MAC address for
Azure Hyper-V NIC SR-IOV [3] is resolved automatically.

Previously kexec-tools will pass "--compress zstd" to dracut. It

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

By comparison, Fedora 35, 36 and 37 Cloud Base Images have multiple
partitions. The root partition which is the last partition has the
following directory,
.
├── home
└── root
├── bin -> usr/bin
├── boot
├── dev
├── etc
├── home
├── root
and the 2nd partition is the boot partition.
This patch address the above changes by mounting {LAST_PARTITION}/root as
to TEMP_ROOT and mount SECOND_PARTITION to TEMP_ROOT/boot. So the test
image can be built successfully.

s390x doesn't use GRUB. To make sure the boot entries are updated, call
zipl after running grubby.

"grubby --zipl" only takes effect when setting default kernel. It's
useless to add "--zipl" when updating kernel command line. Also rename
_update_grub to _update_kernel_cmdline since s390x doesn't use GRUB.

Resolves: bz2104534
When running "kdumpctl reset-crashkernel --kernel=ALL" on s390x,
sed: can't read /etc/default/grub: No such file or directory
sed: can't read /etc/default/grub: No such file or directory
This happens because s390x doesn't use the grub bootloader and
/etc/default/grub doesn't exist.
