67b8dd1cb8 kdump-lib.sh: add a config format and read helper
upstream: fedora
resolves: bz2003832

    kdump-lib.sh: add a config format and read helper

    Add a helper `kdump_read_conf` to replace read_strip_comments.
    `kdump_read_conf` does a few more things:

      - remove trailing spaces.
      - format the content, remove duplicated spaces between name and value.
      - read from KDUMP_CONFIG_FILE (/etc/kdump.conf) directly, avoid pasting
	"/etc/kdump.conf" path everywhere in the code.
      - check if config file exists, just in case.

    Also unify the environmental variable, now KDUMP_CONFIG_FILE stands for
    the default config location.

    This helps avoid some shell pitfalls about spaces when reading config.

    kdump-lib.sh: kdump_get_arch_recommend_size uses crashkernel.default

    The new `crashkernel.default` file in kernel package can be used as the
    ck_cmdline source.

    Also keep the legacy code so old kernel packages will still work.

96a3fc1ac8 fadump: isolate fadump initramfs image within the default one
Resolves: bz1924115
Conflict: None
Upstream: Fedora

commit fa9201b240 (devel)
Author: Hari Bathini <hbathini@linux.ibm.com>
Date:   Wed Jun 23 20:06:48 2021 +0530

    fadump: isolate fadump initramfs image within the default one

    In case of fadump, the initramfs image has to be built to boot into
    the production environment as well as to offload the active crash dump
    to the specified dump target (for boot after crash). As the same image
    would be used for both boot scenarios, it could not be built optimally
    while accommodating both cases.

    Use --include to include the initramfs image built for offloading
    active crash dump to the specified dump target. Also, introduce a new
    out-of-tree dracut module (99zz-fadumpinit) that installs a customized
    init program while moving the default /init to /init.dracut. This
    customized init program is leveraged to isolate fadump image within
    the default initramfs image by kicking off default boot process
    (exec /init.dracut) for regular boot scenario and activating fadump
    initramfs image, if the system is booting after a crash.

    If squash is available, ensure default initramfs image is also built
    with squash module to reduce memory consumption in capture kernel.

    Write to `/var/lib/kdump` if $KDUMP_BOOTDIR not writable

    The `/boot` directory on some operating systems might be read-only.
    If we cannot write to `$KDUMP_BOOTDIR` when generating the kdump
    initrd, attempt to place the generated initrd at `/var/lib/kdump`
    instead.

a9fda5c885 kdumpctl: Add kdumpctl estimate
Resolves: bz1951415
Upstream: fedora
Conflict: none

commit e9e6a2c745
Author: Kairui Song <kasong@redhat.com>
Date:   Thu Apr 22 03:27:10 2021 +0800

    kdumpctl: Add kdumpctl estimate

    Add a rough esitimation support, currently, following memory usage are
    checked by this sub command:

    - System RAM
    - Kdump Initramfs size
    - Kdump Kernel image size
    - Kdump Kernel module size
    - Kdump userspace user and other runtime allocated memory (currently
      simply using a fixed value: 64M)
    - LUKS encryption memory usage

    The output of kdumpctl estimate looks like this:
      # kdumpctl estimate
      Reserved crashkernel:    256M
      Recommanded crashkernel: 160M

      Kernel image size:   47M
      Kernel modules size: 12M
      Initramfs size:      19M
      Runtime reservation: 64M
      Large modules:
          xfs: 1892352
          nouveau: 2318336

    And if the kdump target is encrypted:
      # kdumpctl estimate
      Encrypted kdump target requires extra memory, assuming using the keyslot with minimun memory requirement

      Reserved crashkernel:    256M
      Recommanded crashkernel: 655M

      Kernel image size:   47M
      Kernel modules size: 12M
      Initramfs size:      19M
      Runtime reservation: 64M
      LUKS required size:  512M
      Large modules:
          xfs: 1892352
          nouveau: 2318336
      WARNING: Current crashkernel size is lower than recommanded size 655M.

    The "Recommanded" value is calculated based on memory usages mentioned
    above, and will be adjusted accodingly to be no less than the value provided
    by kdump_get_arch_recommend_size.

    There is requirement to decide the recommended memory size for the current
