mkdumprd: Use the correct syntax to redirect the stderr to null
A space was added by mistake and unfortunately fips-mode-setup refuses
an extra parameter,
# fips-mode-setup --is-enabled 2 > /dev/null
# echo $?
2
# fips-mode-setup --is-enabled 2
Check, enable, or disable the system FIPS mode.
usage: /usr/bin/fips-mode-setup --enable|--disable [--no-bootcfg]
usage: /usr/bin/fips-mode-setup --check
usage: /usr/bin/fips-mode-setup --is-enabled
So in this case mkdumprd can never detect if FIPS is enabled. Fix this
mistake.

mkdumprd: call dracut with --add-device to install the drivers needed by /boot partition automatically for FIPS
Currently, kdump doesn't work on many FIPS-enabled systems including
Azure, ESXI, Hyper, POWER and etc. When FIPS is enabled, it needs to
access /boot//.vmlinuz-xxx.hmac to verify the integrity of the kernel.
However, on those systems, /boot fails to be mounted due to a lack of
fs and block device drivers and the system just halted after failing to
verify the integrity of the kernel. For example, on Hyper-V, sd_mod, sg,
scsi_transport_fc, hv_storvsc and hv_vmbus need to be installed in order
for /boot to be mounted.
mkdumprd calls dracut with the --no-hostonly-default-device. Following
the documentation (man dracut),
--no-hostonly-default-device
Do not generate implicit host devices like root, swap, fstab, etc.
Use "--mount" or "--add-device" to explicitly add devices as needed
this patch uses "--add-device" to explicitly add the device of /boot.
Note there is already an attempt to fix it in dracut's 01fips module
i.e. via the commit 83651776 ("fips: ensure fs module for /boot is
installed"). Unfortunately it only installs the file system driver e.g.
xfs.

Install nfsv4-related drivers when users specify nfs dumping via dracut_args
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2140721
Currently, if users specify dumping to nfsv4 target via
dracut_args --mount "<NFS-server-ip>:/var/crash /mnt nfs defaults"
it fails with the following errors,
[ 5.159760] mount[446]: mount.nfs: Protocol not supported
[ 5.164502] systemd[1]: mnt.mount: Mount process exited, code=exited, status=32/n/a
[ 5.167616] systemd[1]: mnt.mount: Failed with result 'exit-code'.
[FAILED] Failed to mount /mnt.
This is because nfsv4-releted drivers are not installed to kdump initrd.
mkdumprd calls dracut with "--hostonly-mode strict". If nfsv4-related
drivers aren't loaded before calling dracut, they won't be installed.
When users specify nfs dumping via dracut_args, kexec-tools won't mount
the nfs fs beforehand hence nfsv4-related drivers won't be installed.
Note dracut only installs the nfs driver i.e. nfsv3 driver for "--mount
... nfs". So also install nfsv4-related drivers when users specify nfs
dumping via dracut_args. Since nfs_layout_nfsv41_files depends on nfsv4,
the nfsv4 driver will be installed automatically.
As for the reason why we support nfs dumping via dracut_args instead of
asking user to use the nfs directive, please refer to commit 74c6f464
("Support special mount information via 'dracut_args'").

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.

Date: Sat Oct 8 12:09:08 2022 +0800
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.

bash scripts: 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, eg. dump target's name/path/id.
False positives are marked with "# shellcheck disable=SCXXXX", for
example, args are expected to split so it should not be quoted.
And replaced some `cut -d ' ' -fX` with `awk '{print $X}'` since cut
is fragile, and doesn't work well with any quoted strings that have
redundant space.
Following quoting related issues are fixed (check the link
for example code and what could go wrong):

bash scripts: replace '[ ]' with '[[ ]]' for bash scripts
kdumpctl, mkdumprd, *-module-setup.sh only target bash, since they
only run in first kernel and depend on dracut, and dracut depends

This is a batch update done with following command:
`sed -i -e 's/\(\s\)\[\s\([^]]*\)\s\]/\1\[\[\ \2 \]\]/g' kdumpctl, mkdumprd, *-module-setup.sh`

See https://tldp.org/LDP/abs/html/testconstructs.html for more details

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.

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.
