ipcalc is needed for generating 45route-static.conf. However,
on newer Fedora, e.g. 34, dracut-network drops dependency on
dhcp-client which requires ipcalc. Make kexec-tools explicitly
depends on ipcalc.

[PATCH] make use of 'uts_namespace.name' offset in VMCOREINFO
* Required for kernel 5.11
The offset of the field 'init_uts_ns.name' has changed since
kernel commit 9a56493f6942 ("uts: Use generic ns_common::count").
Make use of the offset 'uts_namespace.name' if available in
VMCOREINFO.

[PATCH 2/2] printk: use committed/finalized state values
* Required for kernel 5.10
The ringbuffer entries use 2 state values (committed and finalized)
rather than a single flag to represent being available for reading.
Copy the definitions and state lookup function directly from the
kernel source and use the new states.

[PATCH 1/2] printk: add support for lockless ringbuffer
* Required for kernel 5.10
Linux 5.10 introduces a new lockless ringbuffer. The new ringbuffer
is structured completely different to the previous iterations.
Add support for retrieving the ringbuffer from debug information
and/or using vmcoreinfo. The new ringbuffer is detected based on
the availability of the "prb" symbol.

The dracut module is opportunistic about using the built-in squashfs
support only when available, but the spec file hard requires it. Demote
it to a weak dep to truly make it optional.
This caters to environments which strive to stay minimal, like FCOS and
RHCOS. See https://github.com/coreos/fedora-coreos-config/pull/708 for
details.
Since the logger was introduced into kdump, let's enable it for kdump
so that we can output kdump messages according the log level and save
these messages for debugging.

Kdump service will create kdump initramfs when needed, but it won't
clean up the kdump initramfs on kernel uninstall. So create a kernel
install hook to do the clean up job.

If the directory /etc/kdump/pre.d is optional, then it is hard
to tell between the following cases:
-1. no directory "/etc/kdump/pre.d"
-2. "rm -rf /etc/kdump/pre.d", which removes all scripts under pre.d
For the second case, kdump.img should be rebuilt.
To bail out from this corner case, always creating pre.d and post.d
during rpm installation.

Switch root is never used for kdump image, and this will be helpful to
reduce the initramfs size.
Also increase dracut dependency version and the function is
dracut_no_switch_root is new introduced.

Backport from the upstream makedumpfile devel branch.
commit 989152e113bfcb4fbfbad6f3aed6f43be4455919

[PATCH] Introduce --check-params option
Currently it's difficult to check whether a makedumpfile command-line
is valid or not without an actual panic. This is inefficient and if
a wrong configuration is not tested, you will miss the vmcore when an
actual panic occurs.
In order for kdump facilities like kexec-tools to be able to check
the specified command-line parameters in advance, introduce the
--check-params option that only checks them and exits immediately.

The dracut initqueue may quit immediately and won't trigger any hook if
there is no "finished" hook still pending (finished hook will be deleted
once it return 0).
This issue start to appear with latest dracut, latest dracut use
network-manager to configure the network,
network-manager module only install "settled" hook, and we didn't
install any other hook. So NFS/SSH dump will fail. iSCSI dump works
because dracut iscsi module will install a "finished" hook to detect if
the iscsi target is up.
So for NFS/SSH we keep initqueue running until the host successfully get
a valid IP address, which means the network is ready.
