ppc64: remove rma_top limit
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.

kdumpctl: Optimize _find_kernel_path_by_release regex string
Currently _find_kernel_path_by_release uses grubby and grep to
find the kernel path, if both the normal kernel and it's debug
varient exist, the grep will give more than one kernel strings.
```
kernel="/boot/vmlinuz-5.14.0-139.kpq0.el9.s390x+debug"
kernel="/boot/vmlinuz-5.14.0-139.kpq0.el9.s390x"
```
This will cause an error when installing debug kernel.
```
The param "/boot/vmlinuz-5.14.0-139.kpq0.el9.s390x+debug
/boot/vmlinuz-5.14.0-139.kpq0.el9.s390x" is incorrect

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.

Simplify setup_znet by copying connection profile to initrd
/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
MAC address by renaming a network interface by SUBCHANNELS.

Wait for the network to be truly ready before dumping vmcore
nm-wait-online-initrd.service installed by dracut's 35-networkmanager
module calls nm-online with "-s" which means it returns immediately when
NetworkManager logs "startup complete". Thus it doesn't truly wait for
network connectivity to be established [1]. Wait for the network to be
truly ready before dumping vmcore. There are two benefits brought by
this approach,
- ssh/nfs dumping won't fail because of that the network is not
ready e.g. [2][3]
- users don't need to use workarounds like rd.net.carrier.timeout to
make sure the network is ready

Address the cases where a NIC has a different name in kdump kernel
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.

Reduce kdump memory consumption by not letting NetworkManager manage unneeded network interfaces
By default, NetworkManger will manage all the network interfaces and
try to set interface IFF_UP to get carrier state. Regardless of whether
the network interface is connected to a cable or not, the NIC driver
will allocate memory resources for e.g. ring buffers when setting IFF_UP.
This could be a waste of memory. For example it's found i40e consumes ~15GB
on a power machine. On this machine, i40e manages four interfaces but only
one interface is valid. This patch use "managed=false" to tell
NetworkManager to not manage network interfaces that are not needed by
kdump by putting 10-kdump-netif_allowlist.conf in the initramfs.

Set up kdump network by directly copying NM connection profile to initrd
This patch setup kdump network by directly copying NM connection profile(s)
for different network setup including bond, bridge, vlan, and team. For
vlan network, rename phydev to parent_netif to improve code readability.
With the new approach, the related code to build up dracut cmdline
parameter such rd.route, ip and etc can be cleaned up. And there is no
need to setup dns when copying .nmconnection directly to initrd
either. Note the bootdev dracut command line parameter is only used by
dracut's 35network-legacy and network-manager doesn't use it, remove
related code as well.
Note
1. kdump_setup_vlan/bond/... are no longer called in subshells in order
to modify global variables like unique_netifs
2. The original kdump_install_net is renamed to better reflect its
current function

profiles if there's a connection dir with rd.neednet. For Fedora/RHEL,
this connection dir is /etc/NetworkManager/system-connections. For the
details, please refer to the NetworkManager commit 79885656d3
("initrd: don't add a connection if there's a connection dir with
rd.neednet") [1]. Before the release of NetworkManager >= 1.35.2, we
need to mask /usr/libexec/nm-initrd-generator.

Determine whether IPv4 or IPv6 is needed
According to `man nm-online`,
"By default, connections have the ipv4.may-fail and
ipv6.may-fail properties set to yes; this means that
NetworkManager waits for one of the two address families to
complete configuration before considering the connection
activated. If you need a specific address family configured
before network-online.target is reached, set the corresponding
may-fail property to no."
If a NIC has an IPv4 or IPv6 address, set the corresponding may-fail
property to no. Otherwise, dumping vmcore over IPv6 could fail because
only IPv4 network is ready or vice versa.
Also disable IPv6 if only IPv4 is used and vice versa.

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.

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.

mkdumprd: Improve error messages on non-existing NFS target directories
When kdump is configured with a NFS location, and the remote directory does
not exist, kdump.service fails with a confusing error message.
kdumpctl[2172]: kdump: Dump path "/tmp/mkdumprd.ftWhOF/target/dumps"
does not exist in dump target "10.111.113.2:/srv/kdump"
We just need to print the remote directory "dumps" in such case, because
"/tmp/mkdumprd.ftWhOF/target" is the local temporary mount point.

fadump: avoid non-debug kernel use for fadump case
Since commit c5bdd2d8f1 ("kdump-lib: use non-debug kernels first"),
non-debug kernel is preferred, over the debug variant, as dump capture
kernel to reduce memory consumption. This works alright for kdump as
the capture kernel is loaded using kexec.
In case of fadump, regular boot loader is used to load the capture
kernel. So, the default kernel needs to be used as capture kernel as
well. But with commit c5bdd2d8f1, initrd of a different kernel is
made dump capture capable, breaking fadump's ability to capture dump
properly. Fix this by sticking with the debug variant in case of
fadump.

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

kdump-lib: use non-debug kernels first
Kdump uses currently running kernel as default, but when currently
running kernel is a debug kernel, it will consume more memory,
which may cause out-of-memory and fail to collect vmcore.
Now we will try to use non-debug kernels first if possible.
Also extract the logic of determine KDUMP_KERNEL from
prepare_kdump_bootinfo into a function. This function will return
KDUMP_KERNEL given a kernel version.
