4db9e59e89 kdumpctl: fix target identification for systems without initrd
We get following error on the systems that have everything built-in and no
initrd is used.

	Kernel dev name of /dev/root is not found.
	Dump target /dev/root is probably not mounted.

It happens because `df $path` gets /dev/root from /proc/self/mountinfo.

Fix this by identifying real target device when `df $path` returns
Filesystem as /dev/root.

8eb199cc91 mkdumprd: Do not add "nfs" dracut module explicitly
Kdump explicitly adds "nfs" dracut module in case of nfs dumping,
actually in case of nfs dump, nfs is a mount target, and will be
added into host_fs_types[], thus dracut will add it automatically,
according to 95nfs/module-setup.sh check().

So, we can safely remove all the add_dracut_module "nfs".

74c6f46429 Support special mount information via "dracut_args"
There are some complaints about nfs kdump that users must mount
nfs beforehand, which may cause some overhead to nfs server.
For example, there're thounsands of diskless clients deployed with
nfs dumping, each time the client is boot up, it will trigger
kdump rebuilding so will mount nfs, thus resulting in thousands
of nfs request concurrently imposed on the same nfs server.

We introduce a new way of specifying mount information via the
already-existent "dracut_args" directive(so avoid adding extra
directives in /etc/kdump.conf), we will skip all the filesystem
mounting and checking stuff for it. So it can be used in the
above-mentioned nfs scenario to avoid severe nfs server overhead.

Specifically, if there is any "--mount" information specified via
"dracut_args" in /etc/kdump.conf, always use it as the final mount
without any validation(mounting or checking like mount options,
fs size, etc), so users are expected to ensure its correctness.

NOTE:
-Only one mount target is allowed using "dracut_args" globally.
-Dracut will create <mountpoint> if it doesn't exist in kdump kernel,
 <mountpoint> must be specified as an absolute path.
-Users should do a test first and ensure it works because kdump does
 not prepare the mount or check all the validity.

3095c3741f mkdumprd: Add dracut watchdog module as default option
If dracut watchdog module is enabled then, it includes kernel watchdog
module of active watchdog device in initramfs.

kdump.conf has an option to modify dracut_args. So, if an user passes "-a
watchdog" in dracut_args then dracut will add kernel watchdog module of
active watchdog device in initramfs.

Since, kexec-tools always requires to add kernel watchdog module of active
watchdog device in initramfs, therefore even when an user does not pass any
watchdog option and there exists at least one active watchdog device then
also kexec-tools adds "-a watchdog" in dracut args.

Therefore, if an user does not want to add kernel watchdog module in
initramfs then the person must pass "-o watchdog" in dracut_args.

510084134f module-setup: Don't handle iBFT in kdump
There are several kinds of iSCSI mode rhel support currently.
 - Pure hardware iSCSI
 - iBFT iSCSI
 - Pure software iSCSI

Except for the 1st one that firmware takes care of everything to
make it behave like a local disk, both iBFT and pure software iSCSI
mode need pass information to kdump kernel for configuring them
correctly.

Currently kdump takes iBFT mode as a software iSCSI and collects
the related information to set up software iSCSI in 2nd kernel,
though dracut can detect and collect information to set up iBFT
iSCSI of 2nd kernel. This brings up 2 problems:

1) Redundent information about the related iSCSI is collected. One
is done by kdump, the other is from dracut.

2) These 2 sessions of 2nd kernel for a certain session of 1st kernel
could contain two "ip=xxx" cmdline option. This will cause cmdline
handling error in dracut.

The 1st one is not critical while the 2nd is. In order to avoid above
2 problems, kdump need detect iBFT mode iSCSI and leave it to dracut.
This is what is done in this patch.

81f2c9ea6f get_persistent_dev(): fix name contention with dracut's similar function
Resolves: BZ1348898

dracut-functions.sh defines a get_persistent_dev(). Earlier, we had another
local get_persistent_dev() in mkdumprd, however that was moved to
kdump-lib.sh, so that it can be reused in kdumpctl.

Since, dracut-module-setup.sh (which is dracut's
99kdumpbase/module-setup.sh) sources kdump-lib.sh. Therefore, once dracut
will execute 99kdumpbase module, it's own get_persistent_dev() function is
overwritten by kdump's version. If any other dracut module calls
get_persistent_dev() thereafter then, kdump's version is executed, which was
not expected.

Therefore rename kdump's get_persistent_dev() as kdump_get_persistent_dev()
to avoid any name contention.

9f8fb447c1 module-setup: Use get_ifcfg_filename() to get the proper ifcfg file
The ifcfg file name of <netif> under "/etc/sysconfig/network-scripts/"
may not be "ifcfg-<netif>". For example, for "enp0s25" we are able to
generate its ifcfg like "/etc/sysconfig/network-scripts/ifcfg-enp0s25test"
via network-manager. If we alway assume "ifcfg-<netif>" is there, we will
got the wrong result in some cases.

The issue can be resolved by using the new get_ifcfg_filename() introduced
by PATCH "kdump-lib: Add get_ifcfg_filename() to get the proper ifcfg file",
so we hereby change all the "ifcfg-<netif>" users to use get_ifcfg_filename().

65b0f80a5c kdump-lib: Add get_ifcfg_filename() to get the proper ifcfg file
Previously, we assumed the ifcfg file of a network "interface" is
"/etc/sysconfig/network-scripts/ifcfg-<interface>", but actually
it is not the case.

For example, for network interface "enp0s25", we are able to
generate like "/etc/sysconfig/network-scripts/ifcfg-enp0s25-test"
for it via network-manager.

The "suffix" in "ifcfg-<suffix>" is actually a "configuration"
name not "interface" name, though normally we use the "interface"
name as its "configuration" name. You can refer to "man ifup"
for some detail.

So, this patch adds some assistant helpers to acquire the right
ifcfg file for an interface. Borrow some logic from script below:
"/etc/sysconfig/network-scripts/network-functions"

7aeeb1d17e kdumpctl: force rebuild in case of file system is modified
kdumpctl passes --device argument if dump target is a raw device. It passes
--mount argument if dump target is either mounted as nfs or as a bulk
device. When dump target device is a root device then it does not pass any
of the above two arguments.

After kdumpctl restart, if there is any change in file system which needs
different dracut arguments, then initramfs must be rebuild.

Modification in filesystem for a raw target does not affect dracut
arguments. So, we do not consider to check any modification if raw target
was specified in kdump.conf.

We might need to change dracut arguments if there is some changes in nfs
and ssh target related files. However, we do not consider them in this
patch.

We mainly consider changes in bulk target specified in kdump.conf. We also
consider changes in bulk and nfs file system, if there was no dump target
specified in kdump.conf but dump path is mounting such file systems.

So the initramfs must be rebuild if, either dump target's persistent path
or it's mount point or its file system type changes. If there is no dump
target specified then, both dump path and root path must mount same device,
otherwise rebuild should be triggered.

Some of the examples when we can need a rebuild:

-- "dump target" is specified as one of ext[234], xfs or btrfs. But after
kdump initramfs building its UUID is changed by reformatting.
-- "dump target" is specified as file system type fs1 (say ext3). But after
kdump initramfs building, user change it to fs2 (say ext4), probably by
a mkfs.ext4 executing on the target device.
-- "dump target" is not specified, but "dump path" mounts a device which
is different than device for root path and either UUID or file system type
is modified after kdump initramfs build.
-- "dump target" is not specified, but "dump path" mounts a nfs device and
nfs host path changes after kdump initramfs build.

Some testing:

Initial conditions:
-- No dump target specified
-- dump path (/var/crash) and root(/) are on same device
-- kdumpctl was already executed once after last modification in
/etc/kdump.conf

    Properly align powerpc64 .toc

    gcc leaves .toc byte aligned, relying on the linker to align the section.

        * kexec/arch/ppc64/kexec-elf-rel-ppc64.c (machine_verify_elf_rel):
        Fudge alignment of .toc section.

    ppc64: purgatory: Handle local symbols in ELF ABIv2

    The PowerPC64 ELF ABIv2 has the concept of global and local symbols
    and information on this is encoded in sym->st_other. When doing a
    R_PPC64_REL24 branch we want to hit the local entry point, so adjust
    it as necessary.

    Pass struct mem_sym into machine_apply_elf_rel()

    On PowerPC64 ABIv2 we need to look at the symbol to determine
    if it has a local entry point. Pass struct mem_sym into
    machine_apply_elf_rel() so we can.
