e30ad0a4ec kdump: Basic iscsi target dump support (software initiator)
BZ: 822701

This patch implements basic software iscsi dump support. Complex iscsi
setups like ibft etc might not work.

iscsi self configuration logic is currenlty part of kdump module. At some
point of time I would like to see it in dracut iscsi module instead of
kdump module when iscsi and other subsystems become self configuration aware
for general boot.

This patch will require work for complex setups. Some of them are.

- IPV6 support
- IBFT support
- Parsing some more advanced parameters and passing to netroot option.

bf247cb56c kdump: Move network device setup in a separate function
BZ: 822701

This allows to reuse same function from iscsi setup code too. Also makes
code more modular.

[dyoung: add a missed space]

ca94c80a91 add rhcrashkernel-param.sh for anaconda use
Resolves: 707441

Provide a script rhcrashkernel-param.sh to generate cmdline, so anaconda can just
call it, we can easily add more logic into this script later.

Note: Currently for fedora only adding null output for testing purpose.

bbd2e7d30a remove dracut-files.tbz2 [v2]
Resolves: bz816864

currently kexec-tools maintains kdump dracut modules as below dir hierarchy:
 [dave@localhost fedpkg]$ tree kexec-tools/kdump_dracut_modules
 kexec-tools/kdump_dracut_modules
 `-- 99kdumpbase
     |-- kdump.sh
     `-- module-setup.sh

But in kexec-tools.spec, sources line is below:
Source100: dracut-files.tbz2

So we need to manually generate the dracut-files.tbz2, upload it, modify
the sources file which contains the md5sum of these binaies, and then do
the building. The more headache problem is this make local tests of
changes to kdump module hard.

To ease future work, move the files to TOPDIR, cp the sources instead.

Thanks for help from dzickus
[v1->v2]: Also remove dracut-files.tbz2 from sources file

015dd4c67c mkdumprd: Start using --hostonly and --add kdumpbase while calling dracut
BZ: 817044

Harald suggested that we use --add kdumpbase instead of -m kdumpbsae. As
-m means only use modules specified on the command line. I am not sure
that kdump will ever know the list of modules it wants to use. It might
be a good idea to let dracut decide it based on --mount option.

Also start using --hostonly to make sure atleast our default dumping to
root disk always works.

I also noticed that with --add and --hostonly initramfs size came down. So
for the time being just bring down the initramfs size.

But it still looks big and this area will require more experimentation and
bug fixing to make sure we are generatiing optimal size images for kdump
purposes and get rid of bloat. I am just beginning to understand dracut,
so expect more churn in this area down the line from me.

I am posting this patch for the bz opened again F18. As it is reducing
initramfs size significantly, I think it is a good idea to commit it
in F17 branch also.

Following is image size comparision.

Dump to root disk.
------------------
vanilla compressed: 13MB
hostonly compressed: 7.5MB

Dump to nfs
-----------
vanilla compressed: 24MB
hostonly compressed: 13MB

Dump over ssh
-------------
vanilla compressed: 23.5 MB
hostonly compressed: 12 MB

de42bcce80 move kdump script order to the end of pre pivot
Resolves: bz816860

dracut pre-pivot hook splited to two hooks: pre-pivot and pre-pivot-cleanup
all the cleanup related scripts are moved to pre-pivot-cleanup hook

Because we depends on some early scripts like fstab-sys, also we must run before
cleanup stuff like dhclient killing, so just move kdump script to the end of
pre-pivot hook

b71fc17869 remove multi dump [v2]
remove multi dump

Resolves: bz816859

multi dump was not written as a failsafe dump. Also it was not really tested.
It introduced more complexity in the early phase of porting plenty of rhel6
functions, so we'd remove it and concentrate on the base functionalities.

f590d235e0 Handle net option for nfs in kdump.conf correctly
Resolve: bug 807521

The fix is easy.

Command sed should be called with option -n to remain slience when DUMP_TARGET
is a nfs server like 'nfs.server:/mnt/testarea/nfs'.

Then nfs function check_ssh_config will return 1 to not to config nfs like a
ssh dump

ba0aa24316 Add ssh dump support
Add ssh dump support

changes including below items:
1. sshkey option
2. sshkey propagate
3. fix a bug of  _server ip calculation for dump target string
4. change the prefix of kdump hook from 93 to 01 to avoid dhclient and
   other cleanups happening before us
5. enable network with dracut cmdline rd.neednet=1 when there's network
   target config

[v1 - v2]:
Only check_ssh_target when there's ssh dump target in kdump config file

[v2 -> v3]
style fixes: trailing spaces and space before tab indent
remove set -x
simply check_ssh_target
use awk to get sshkey option value
change pivot hook order to 0000
