d53e0655f1 kdump-lib.sh: reformat with shfmt
upstream: fedora
resolves: bz2003832
conflict:
    Regenerated with shfmt command because of
    too much hunk patches. When comparing with the original
    patch, only patch "kdumpctl: enable secure boot on ppc64le LPARs"
    related hunks are different.

    kdump-lib.sh: fix variable quoting issue

    Fixed quoting issues found by shellcheck, no feature
    change. This should fix many errors when there is space
    in any shell variables.

    And fixed how remove_cmdline_param is being called in prepare_cmdline.
    Kernel parameters can have space like: param="spaces in here". So currently
    remove_cmdline_param is broken since its args always get split by space.
    But prepare_cmdline is expecting remove_cmdline_param to split its args
    by space and passing a list of kernel args separated by space as a whole arg.
    So fix that by using `xargs` to parse and split the args properly, then
    call remove_cmdline_param.

    Following quoting related issues are fixed (check the link
    for example code and what could go wrong):

    Remove trace_buf_size and trace_event from the kernel bootparameters of the kdump kernel

    The kdump kernel uses resources for ftrace because trace_buf_size, which
    specifies the ring buffer size for ftrace, and trace_event, which specifies
    a valid trace event, are not removed, but the kdump kernel does not require
    ftrace.

    trace_buf_size is ignored if the specified size is 0, so specify 1.

c9f583baa4 kdump-lib.sh: rework nmcli related functions
upstream: fedora
resolves: bz2003832
conflict: none

commit 58d3e6db3a
Author: Kairui Song <kasong@redhat.com>
Date:   Wed Sep 8 15:20:42 2021 +0800

    kdump-lib.sh: rework nmcli related functions

    This fixes word splitting issue with nmcli args. Current kexec-tools
    scripts won't call nmcli with correct arguments when there are space in
    network interface name.

    nmcli expects multiple parameters, but get_nmcli_value_by_field only
    accepts two params and depends on shell word splitting to split the
    _nm_show_cmd into multiple params, which is very fragile.
    So switch the param order, simplified this function and now multiple
    params can be used properly.

    And get_nmcli_connection_show_cmd_by_ifname returns multiple
    nmcli params in a single variable, it depend on shell word splitting to
    split the words when calling nmcli. But this is very fragile and break
    easily when there are any special character in the connection path.

    This function is only introduced to get and cache the nmcli command
    which contains the "connection name".

    Actually only cache the "connection path" is enough. Callers should
    just call get_nmcli_connection_apath_by_ifname to cache the path, and
    a new helper get_nmcli_field_by_conpath is introduced here to get value
    from nmcli. This way "connection path" can contain any character.

    Also get rid of another nmcli_cmd usage in
    get_nmcli_connection_apath_by_ifname which stores multiple params in a
    single bash variable separated by space.

35519c3eca kdump-lib-initramfs.sh: prepare to be a POSIX compatible lib

commit a5faa052d4
Author: Kairui Song <kasong@redhat.com>
Date:   Tue Sep 14 03:25:46 2021 +0800

    kdump-lib-initramfs.sh: prepare to be a POSIX compatible lib

    Move all functions needed in the second kernel from kdump-lib.sh
    to kdump-lib-initramfs.sh, and update shebang headers.

    Now, kdump-lib-initramfs.sh is an independent lib script, no longer
    depend on kdump-lib.sh, and kdump-lib.sh is no longer needed for
    the second kernel.

    In later commits, functions in kdump-lib-initramfs.sh will be reworked
    to be POSIX compatible, kdump-lib.sh will contain bash only functions.

    POSIX shell have very limited features, eg. `local` keyword doesn't
    exist in POSIX but we rely on that heavily. So kdump-lib.sh will
    use bash syntax and contain the most complex helper and codes.

    kdump-lib-initramfs.sh will contain the minimum set of helpers,
    and be shared by both the first and second kernel.

14205c1d6f kdump-lib.sh: add a config value retrive helper
upstream: fedora
resolves: bz2003832
conflict: none

commit 09ccf88405
Author: Kairui Song <kasong@redhat.com>
Date:   Mon Aug 16 23:25:14 2021 +0800

    kdump-lib.sh: add a config value retrive helper
    Add a helper kdump_get_conf_val to replace get_option_value.

    It can help cover more corner cases in the code, like when there are
    multiple spaces in config file, config value separated by a tab,
    heading spaces, or trailing comments.

    And this uses "sed group command" and "sed hold buffer", make it much
    faster than previous `grep <config> | tail -1`.

    This helper is supposed to provide a universal way for kexec-tools
    scripts to read in config value. Currently, different scripts are
    reading the config in many different fragile ways.

    For example, following codes are found in kexec-tools script code base:
      1. grep ^force_rebuild $KDUMP_CONFIG_FILE
	 echo $_force_rebuild | cut -d' '  -f2

      2. grep ^kdump_post $KDUMP_CONFIG_FILE | cut -d\  -f2

      3. awk '/^sshkey/ {print $2}' $conf_file

      4. grep ^path $KDUMP_CONFIG_FILE | cut -d' '  -f2-

    1, 2, and 4 will fail if the space is replaced by, e.g. a tab

    1 and 2 might fail if there are multiple spaces between config name
    and config value:
    "kdump_post  /var/crash/scripts/kdump-post.sh"
    A space will be read instead of config value.

    1, 2, 3 will fail if there are space in file path, like:
    "kdump_post /var/crash/scripts dir/kdump-post.sh"

    4 will fail if there are trailing comments:
    "path /var/crash # some comment here"

    And all will fail if there are heading space,
    " path /var/crash"

    And all will most likely cause problems if the config file contains
    the same option more than once.

    And all of them are slower than the new sed call. Old get_option_value
    is also very slow and doesn't handle heading space.

    Although we never claim to support heading space or tailing comments
    before, it's harmless to be more robust on config reading, and many
    conf files in /etc support heading spaces. And have a faster and
    safer config reading helper makes it easier to clean up the code.

67b8dd1cb8 kdump-lib.sh: add a config format and read helper

Author: Kairui Song <kasong@redhat.com>
Date:   Tue Aug 3 19:49:51 2021 +0800

    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.

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.

    kdumpctl: Add kdumpctl estimate

    Add a rough esitimation support, currently, following memory usage are

    - 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

      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

      WARNING: Current crashkernel size is lower than recommanded size 655M.

    The "Recommanded" value is calculated based on memory usages mentioned

Conflict: None

commit 18131894b6
Author: Pingfan Liu <piliu@redhat.com>
