This patch introduce a new kdump-capture.service which is used to run
kdump.sh.
kdump-capture.service has OnFailure=emergency.target and
OnFailureIsolate=yes set. When kdump.sh fails, the kdump emergency
service will be triggered and enter the error handling path.
In 2nd kernel, the default target for systemd is initrd.target, so we
put kdump-capture.service in initrd.target.wants/ and by that, system
will start kdump-capture as part of the boot process.
kdump.sh used to run in dracut-pre-pivot hook. Now kdump-capture.service
is placed after dracut-pre-pivot.service and other dependencies are all
copied from dracut-pre-pivot.service. So the start point of
kdump.sh will be almost the same as it used to be.

Now upon failure kdump script might not be called at all and it might
not be able to execute default action. It results in a hang.
Because we disable emergency shell and rely on kdump.sh being invoked
through dracut-pre-pivot hook. But it might happen that we never call
into dracut-pre-pivot hook because certain systemd targets could not
reach due to failure in their dependencies. In those cases error
handling code does not run and system hangs. For example:
sysroot-var-crash.mount --> initrd-root-fs.target --> initrd.target \
--> dracut-pre-pivot.service --> kdump.sh
If /sysroot/var/crash mount fails, initrd-root-fs.target will not be
reached. And then initrd.target will not be reached,
dracut-pre-pivot.service wouldn't run. Finally kdump.sh wouldn't run.
To solve this problem, we need to separate the error handling code from
dracut-pre-pivot hook, and every time when a failure shows up, the
separated code can be called by the emergency service.
By default systemd provides an emergency service which will drop us into
shell every time upon a critical failure. It's very convenient for us to
re-use the framework of systemd emergency, because we don't have to
touch the other parts of systemd. We can use our own script instead of
the default one.
This new scheme will overwrite emergency shell and replace with kdump
error handling code. And this code will do the error handling as needed.
Now, we will not rely on dracut-pre-pivot hook running always. Instead
whenever error happens and it is serious enough that emergency shell
needed to run, now kdump error handler will run.
dracut-emergency is also replaced by kdump error handler and it's
enabled again all the way down. So all the failure (including systemd
and dracut) in 2nd kernel could be captured, and trigger kdump error
handler.
dracut-initqueue is a special case, which calls "systemctl start
emergency" directly, not via "OnFailure=emergency". In case of failure,
emergency is started, but not in a isolation mode, which means
dracut-initqueue is still running. On the other hand, emergency will
call dracut-initqueue again when default action is dump_to_rootfs.
systemd would block on the last dracut-initqueue, waiting for the first
instance to exit, which leaves us hang. It looks like the following:
dracut-initqueue (running)
--> call dracut-emergency:
--> dracut-emergency (running)
--> kdump-error-handler.sh (running)
--> call dracut-initqueue:
--> blocking and waiting for the original instance to exit.
To fix this, I'd like to introduce a wrapper emergency service. This
emegency service will replace both the systemd and dracut emergency. And
this service does nothing but to isolate to real kdump error handler
service:
dracut-initqueue (running)
--> call dracut-emergency:
--> dracut-emergency isolate to kdump-error-handler.service
--> dracut-emergency and dracut-initqueue will both be stopped
and kdump-error-handler.service will run kdump-error-handler.sh.
In a normal failure case, this still works:
foo.service fails
--> trigger emergency.service
--> emergency.service isolates to kdump-error-handler.service
--> kdump-error-handler.service will run kdump-error-handler.sh

Now when mount in /etc/fstab fails, systemd would not consider it as
critical and it would continue to boot. In fact, emergency service is
triggered, but not in a isolation mode, and it results in the emergency
service getting shutdown at some point later of the boot process. We
need isolation otherwise we won't see any emergency service.
That is because in kdump initramfs, mount units specified in /etc/fstab
are required by "local-fs.target". When any of these mounts fails,
local-fs.target fails.
For kdump initramfs, we need to isolate to emergency service on any of
the mount failure, that said, every service should be stopped and onlu
emergency service would run. But local-fs.target won't trigger that on
its failure. That means in case of mount failure, local-fs.target also
enters failure state, but all the service will continue without any
interruption.
After digging looking into source code of systemd-fstab-generator. I
find "x-initrd.mount" using in initramfs mount, will make the mount
units required by "initrd-root-fs.target" rather than it's used to be
"local-fs.target".
"initrd-root-fs.target" is suitable to us because if it fails, it will
isolate to emergency service. That means in case of any mount failure,
the emergeny service will start and everything else will stop. We want
this effect because we need to take kdump fail-safe action when there's
a mount failure.
From systemd unit point of view, "initrd-root-fs.target" has
OnFailureIsolate=yes, but "local-fs.target" doesn't. From
systemd.unit(5):
OnFailureIsolate=
Takes a boolean argument. If true, the unit listed in OnFailure=
will be enqueued in isolation mode, i.e. all units that are not its
dependency will be stopped. If this is set, only a single unit may
be listed in OnFailure=. Defaults to false.
NOTE: Harald who contributed "x-initrd.mount" in systemd, confirmed that
this feature will stay.

This patch does the following change in 2nd kernel:
- dump target is mounted under /sysroot
With this change, we don't need to track what we've mounted in 2nd
kernel. We can just umount recursively every mount in /sysroot by
command:
umount -R /sysroot
It's very convenient to do so, because it's hard to track what we've
mounted when we're in error handling path (later patches). So mount
everything under /sysroot is reasonable and practical for us.

The script dracut-kdump.sh is responsible for capturing vmcore during
second kernel boot. Currently this script gets installed into kdump
initrd as part of kdumpbase dracut module.
With fadump support, 'dracut-kdump.sh' script also gets installed into
default initrd to capture vmcore generated by firmware assisted dump.
Thus in fadump case, the same initrd is going to be used for normal
boot as well as boot after system crash. Hence a check is required to
see if it is a normal boot or boot after crash.
A new node "ibm,kernel-dump" is added, to the device tree, by firmware
to notify kernel if it is booting after crash. The below patch adds a
check for this node before executing steps to capture vmcore. This
check will help bypassing the vmcore capture steps during normal boot
process.

The current kdump infrastructure builds a separate initrd which then
gets loaded into memory by kexec-tools for use by kdump kernel. But
firmware assisted dump (FADUMP) does not use kexec-based approach.
After crash, firmware reboots the partition and loads grub loader
like the normal booting process does. Hence in the FADUMP approach,
the second kernel (after crash) will always use the default initrd
(OS built). So, to support FADUMP, change is required, as in to add
dump capturing steps, in this initrd.
The current kdumpctl script implementation already has the code to
build initrd using mkdumprd. This patch uses the new '--rebuild'
option introduced, in dracut, to incrementally build the initramfs
image. Before rebuilding, we may need to probe the initrd image for
fadump support, to avoid rebuilding the initrd image multiple times
unnecessarily. This can be done using "lsinitrd" tool with the newly
proposed '--mod' option & inspecting the presence of "kdumpbase" in
the list of modules of default initrd image. We rebuild the image if
only "kdumpbase" module is missing in the initrd image. Also, before
rebuilding, a backup of default initrd image is taken.
Kexec-tools package in rhel7 is now enhanced to insert a out-of-tree
kdump module for dracut, which is responsible for adding vmcore
capture steps into initrd, if dracut is invoked with "IN_KDUMP"
environment variable set to 1. mkdumprd script exports "IN_KDUMP=1"
environment variable before invoking dracut to build kdump initrd.
This patch relies on this current mechanism of kdump init script.

We met a problem that eth0 ends up being eth1 and eth1 being eth0
between 1st and 2nd kernel. Because we pass ifname=eth0:$mac to force
it's named eth0 and since "eth0"is already taken by the other NIC, udev
fails to bring up the NIC we want, thus kdump fails.
kernel assigned network interface names are not persistent. So if first
kernel is using kernel assigned interface names, then force it to use
"kdump-" prefixed names in second kernel.
For ethX, we put a prefix "kdump-" before it, so in 2nd kernel, ethX
will name to "kdump-ethX". So that we can avoid the naming conflict.

freed by free_bitmap2_buffer_cyclic(). At the same time, remove
thoes frees that free partial_bitmap1 or partial_bitmap2 at the end
of main() because partial_bitmap1 and partial_bitmap2 has been freed
after dump file has been written out, so there is no need to free it
