Install the driver of physical device for a SR-IOV virtual device
Currently, network dumping failed over a NIC that is a Single Root I/O
Virtualization (SR-IOV) virtual device. Usually the driver of the
virtual device won't specify the dependency on the driver of the
physical device. So to fix this issue, the driver of the physical device
needs to be found and installed as well.

Try to install PHY and MDIO bus drivers explicitly
Resolves: https://issues.redhat.com/browse/RHEL-7028
Currently, nfs dumping fails on some machines that has a dedicated PHY
driver (dealing with the physical layer) or MDIO bus (connecting the MAC
to PHY devices) driver. This is because kexec-tools doesn't install
dedicated PHY or MDIO driver explicitly. Usually a NIC driver shouldn't
specify the dependency on the needed PHY or MDIO driver because it
shouldn't a NIC (medium access control, MAC) driver is for dealing with
the Data link layer and a PHY driver is for physical layer. So as long
as a MAC driver can talk to the PHY layer via APIs, it shouldn't care
which PHY driver or device it's talking to. So when the
dependency on a PHY driver or MDIO driver is not found by dracut's
instmods, the PHY or MDIO driver won't be installed.
This patch passes =drivers/net/phy and =drivers/net/mdio to dracut's
instmods which will only install in-use PHY or MDIO driver(s).
Note ideally we should find out which PHY driver is used by a NIC but
unfortunately currently no universal way can be found
(/sys/class/net/NIC_NAME/phydev/driver/module can be used to find the
name of the PHY driver for some NICs but it doesn't exist for some NICs
like Qualcomm Atheros AR8031). So is it for a MDIO bus driver.
Fortunately currently no huge memory consumption is found for a PHY or
MDIO driver.

dracut-module-setup: Skip initrd-cleanup and initrd-parse-etc in kdump
When using multipath devices as the target for kdump, if user_friendly_name
is also specified, devices default to names like "mpath*", e.g., mpatha.
In dracut, we obtain a persistent device name via get_persistent_dev. However,
dracut currently believes using /dev/mapper/mpath* could cause issues, thus
alternatively names are used, here it's /dev/disk/by-uuid/<FS_UUID>.
During the kdump boot progress, the /dev/disk/by-uuid/<FS_UUID> will exist as
soon as one of the path devices exists, but it won't be usable by systemd,
since multipathd will claim that device as a path device. Then multipathd will
get stopped before it can create the multipath device.
Without user_friendly_name, /dev/mapper/<WWID> is considered a persistent
device name, avoiding the issue.
The exit of multipathd is due to two dependencies in the current dracut module
90multipath/multipathd.service, "Before=initrd-cleanup.service" and
"Conflicts=initrd-cleanup.service".
As per man 5 systemd.unit, if A.service has "Conflicts=B.service", starting
B.service will stop A.service.
This is useful during normal boot. However, we will never switch-root after
capturing vmcore in kdump.
We need to ensure that multipathd is not killed due to such dependency issue.
Without modifying multipathd.service, we add ConditionPathExists=!/proc/vmcore
to skip initrd-cleanup.service in kdump. This approach is beneficial as
it avoid the potential termination of other services that conflict with
initrd-cleanup.service. Also skip initrd-parse-etc.service as it will try to
start initrd-cleanup.service. Both of these services are used for switch root,
so they can be safely skipped in kdump.

Use the same /etc/resolve.conf in kdump initrd if it's managed manually

Previously fix 0177e248 ("Use the same /etc/resolve.conf in kdump initrd

1) it generated .conf file unrecognized by NetowrkManager ;
2) this .conf file was installed to current file system instead of to the kdump initrd;
3) this incorrect .conf file prevented the starting of NetworkManager.

kdumpctl: Only returns immediately after an error occurs in check_*_modified
Currently is_system_modified will return immediately when check_*_modified
return a non-zero value, and the remaining checks will not be executed.
For example, if there is a fs-related error exists, and someone changes the
kdump.conf, check_files_modified will return 1 and is_system_modified will
return 1 immediately. This will cause kdumpctl to skip check_fs/drivers_modified,
kdump.service will rebuild the initrd and start successfully, however, any
errors should prevent kdump.service from starting.
This patch will cause check_*_modifed to continue running until an error occurs
or all execution ends.

kdump-lib.sh: add extra 64M to default crashkernel if sme/sev is active
It's reported that kdump kernel failed to boot and can't dump vmcore
when crashkernel=192M and SME/SEV is active.
This is because swiotlb will be enabled and reserves 64M memory by
default on system with SME/SEV enabled. Then kdump kernel will be out of
memory after taking 64M away for swiotlb init.
So here add extra 64M memory to default crashkernel value so that kdump
kernel can function well as before. When doing that, search journalctl
for the "Memory Encryption Features active: AMD" to check if SME or SEV
is active. This line of log is printed out in kernel function as below
and the type SME is mutual exclusive with type SEV.
***:
arch/x86/mm/mem_encrypt.c:print_mem_encrypt_feature_info()
Note:
1) The conditional check is relying on journalctl log because I didn't
find available system interface to check if SEV is active. Even
though we can check if SME is active via /proc/cpuinfo. For
consistency, I take the same check for both SME and SEV by searching
journalctl.
2) The conditional check is relying on journalctl log, means it won't
work for crashkernel setting in anoconda because the installation
kernel doesn't have the SME/SEV setting. So customer need manually
run 'kdumpctl reset-crashkernel' to reset crashkernel to add the
extra 64M after OS installation.
3) We need watch the line of log printing in
print_mem_encrypt_feature_info() in kernel just in case people may
change it in the future.

Furthermore require the delta to have a explicit unit, i.e. no longer

Kernel signing key is deleted once kdump is loaded. This causes confusion in

Introduce a function to get reserved memory size
The size of the reserved memory in the functions show_reserved_mem,
check_crash_mem_reserved, and do_estimate are fetched from the sysfs
node `/sys/kernel/kexec_crash_size`. However, in the case of fadump,
the reserved area size is instead present in
/sys/kernel/fadump/mem_reserved.
For example:
$ kdumpctl showmem
kdump: Dump mode is fadump
kdump: Reserved 0MB memory for crash kernel
The above command showed 0MB for Reserved memory which is incorrect, the
actual reservation was 2048MB.
To resolve this issue a new helper function is introduced to fetch
reserved memory size based on the dump mode. For "fadump" mode,
it looks in `/sys/kernel/fadump/mem_reserved`, otherwise, it uses
`/sys/kernel/kexec_crash_size`. And all functions that previously
fetching reserved memory directly from `/sys/kernel/kexec_crash_size`
sysfs node are now updated to use this new function to get the reserved
memory size.
With the fix in place, the `kdumpctl showmem` command will now display
correct reserved memory size.
$ kdumpctl showmem
kdump: Dump mode is fadump
kdump: Reserved 2048MB memory for crash kernel

kdumpctl: merge check_current_{kdump,fadump}_status
Both functions are almost identical. The only differences are (1) the
sysfs node the status is read from and (2) the fact the fadump version
doesn't verify if the file it's trying to read actually exists. Thus
merge the two functions and get rid of the check_current_status wrapper.
While at it rename the function to is_kernel_loaded which explains
better what the function does.
Finally, after moving FADUMP_REGISTER_SYS_NODE shellcheck can no longer
access the definition and starts complaining about it not being quoted.
Thus quote all uses of FADUMP_REGISTER_SYS_NODE.

kdump-lib: add support for 64K aarch64
On aarch64, both 4K and 64K kernel can be installed, while they demand
different size reserved memory for kdump kernel.
'get_conf PAGE_SIZE' can not work if installing a 64K kernel when
running a 4K kernel. Hence resorting to the kernel release naming rules.
At present, the 64K kernel has the keyword '64k' in its suffix.
The base line for 64K is decided based on 4K. The diff 100M is picked up
since on a high end machine without smmu enabled, the diff of MemFree is
82M.
As for the smmu case, a huge difference in the memory consumption lies
between 64k and 4k driver. And it should be calculated separatedly.

Simplify the management of the kernel parameter crashkernel
Currently, kexec-tools only updates the crashkernel to a new default
value only when both two conditions are met,
- auto_reset_crashkernel=yes in kdump.conf
- existing kernels or current running kernel should use the old default
value.
To address seen corner cases, the logic to tell if the second condition
is met becomes quite complex. Instead of making the logic more complex
to support aarch64-64k, this patch drops the second condition to
simplify the management of the crashkernel kernel parameter.
Another change brought by this simplification is kexec-tools will also
set up the kernel crashkernel parameter for a fresh install (previously
it's limited to osbuild).
Note
1. This patch also stop trying to update /etc/default/grub because
a) it only affects the static file /boot/grub2/grub.cfg
b) grubby is recommended to change the kernel command-line parameters
for both Fedora [1] and RHEL9 [2][3]
c) For the cases of aarch64 and POWER, different kernels could have
different default crashkernel value.
2. Starting with Fedora 37, posttrans rpm scriplet distinguish between
package install and upgrade.

kdump-lib: fix the matching pattern for debug-kernel
On aarch64, a 64k kernel's name looks like:
vmlinuz-5.14.0-300.el9.aarch64+64k and the corresponding debug kernel's
name looks like: vmlinuz-5.14.0-300.el9.aarch64+64k-debug, which ends
with the suffix -debug instead of +debug.
Fix the matching pattern by [+|-]debug

kdump-lib: always specify version in is_squash_available
is_squash_available is only used in dracut-module-setup.sh and mkdumprd.
Neither of the two scripts calls prepare_kdump_bootinfo which determines
and sets KDUMP_KERNELVER. Thus KDUMP_KERNELVER is only non-zero if it
explicitly specified by the user in /etc/sysconfig/kdump (and the file
gets sourced, which is not the case for drachu-module-setup.sh).
In theory this can even lead to bugs. For example consider the case when
a debug kernel is running. In that case kdumpctl will try to use the
non-debug version of the kernel while is_squash_available will make its
decision based on the debug version. So in case the debug kernel has
squash available but the non-debug kernel doesn't mkdumprd will try to
add it nevertheless.
Thus factor out the kernel version detection from prepare_kdump_bootinfo
and make use of the new function when checking for the availability of
those kernel modules.

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.

kdumpctl: Add basic UKI support
A Unified Kernel Image (UKI) is a single EFI PE executable combining an
EFI stub, a kernel image, an initrd image, and the kernel command line.
They are defined in the Boot Loader Specification [1] as type #2
entries. UKIs have the advantage that all code as well as meta data that
is required to boot the system, not only the kernel image, is combined
in a single PE file and can be signed for EFI SecureBoot. This extends
the coverage of SecureBoot extensively.
For RHEL support for UKI were included into kernel-ark with 16c7e3ee836e
("redhat: Add sub-RPM with a EFI unified kernel image for virtual
machines").
There are two problems with UKIs from the kdump point of view at the
moment. First, they cannot be directly loaded via kexec_file_load and
second, the initrd included isn't suitable for kdump. In order to enable
kdump on systems with UKIs build the kdump initrd as usual and extract
the kernel image before loading the crash kernel.

kdumpctl: Move temp file in get_kernel_size to global temp dir
Others will need to use a temporary files, too. In order to avoid
potential clashes of multiple trap handlers move the local temp file
into a global temp dir.
While at it make sure that the trap handler returns the correct exit
code.

kdump-lib: fix prepare_cmdline
A recently added unit test found that prepare_cmdline has several
problems. For example an empty remove list will remove all spaces or
when the cmdline contains a parameter with quoted values containing
spaces will only remove the beginning up to the first space. Furthermore
the old design requires lots of subshells and pipes.
This patch rewrites prepare_cmdline in a way that makes the unit test
happy and tries to use as many bash built-ins as possible.
