83ef43e522 mkdumprd: return error if no write permission on save path of server for ssh
When ssh dump, if user doesn't have write permission on save path
of server, the crash kernel can be loaded successfully, but finally
kdump will fail because write is not allowed.

Let's check it in the service start phase, if no write permission
print error message and exit.

For differentiation, change the name of old function mkdir_save_path
to mkdir_save_path_fs.

928c5f1294 mkdumprd: remove -M option for dracut
We shouldn't output what dracut module are used when rebuilding kdump
initrd. It's confusing to user.

And since we've introduced dracut_args in kdump.conf, we can safely
remove this mandatory -M and let user add as his/her need.

fe96b47828 add dracut_args option to kdump.conf
mkdumprd call dracut to rebuilding kdump initrd, sometimes passing extra
dracut args is helpful. For example user can enable debug output with
--debug, --printsize to print roughly increased initramfs size by each module,
--omit-drivers to omit kernel modules, etc.

This patch enables dracut_args option for passing extra args to dracut.
Also it modifies add_dracut_arg() to treat a string with-in quote as single
string because for dracut options which has its own args, the args need to be
quoted and space seperated.

If add_dracut_arg() gets an string read from kdump.conf and if that string
contains double quotes, then while converting to positional parameters
those double quotes are not interpreted. Hence if /etc/kdump.conf contains
following.

dracut_args --add-drivers "driver1 driver2"

then add_dracut_args() sees following positional parameters

$1= --add-drivers
$2= "driver1
$3= driver2"

Notice, double quotes have been ignored and parameters have been broken
based on white space.

Modify add_dracut_arg() to look for parameters starting with " and
if one is found, it tries to merge all the next parameters till one
is found with ending double quote. Hence effectively simulating
following behavior.

$1= --add-drivers
$2= "driver1 driver2"

[v1->v2]: address quoted substring in dracut_args, also handle the leading
and ending spaces in substring.
[v2->v3]: fix dracut arguments seperator in kdump.conf.
[v3->v4]: improve changelog, thanks vivek.
[v4->v5]: make the manpage more verbose [vivek].

Tested with below dracut_args test cases:
1. dracut_args --add-drivers "pcspkr virtio_net" --omit-drivers "sdhci-pci hid-logitech-dj e1000"
2. dracut_args --add-drivers "   pcspkr virtio_net   " --omit-drivers "sdhci-pci hid-logitech-dj e1000"

1effb09942 error out if dump target is encrypted
We do not support dump to an encrypted disk now, so adding the functions to
error out if any of the dump target is encrypted.

This patch is based on the check resettable patches from BaoQuan which added
some dracut functions for iterating block devices.

Currently dracut support an encrypted rootfs, but it need interacive entering
passcode. It might be possible to use some keyfile to pass the key checking.
But let's fisrtly check and error out. In the future if there's such
requirement we can look into it that time.

Tested in F18 with encrypted root, encrypted disk other than root and
dump_to_rootfs with encrypted root.

4b850d2f3a Check if block device as dump target is resettable
Some Smart Array (hpsa/cciss) adapters don't support reset, we need
to disable kdump on those devices, like rhel6 did.

In this patch, the dump target  is checked according to below
criteria if it's a block device.
If it's cciss disk but is resettbale, can be used as dump target.
If it's cciss disk but is not resettable, can not be used as dump
target.
If it's cciss disk and not resettable, but user set OVERRIDE_RESETTABLE
to 1 in /etc/sysconfig/kdump, can be taken as dump target. Because
user know the situation and want to have a try.

In this patch, added codes include 4 parts:
1)Add an option "override_resettable <0 | 1>" into kdump.conf, and
add related section into kdump.conf man page. In mkdumprd, will check
whether user has set a value, get that value if yes. By default, the
value is 0.

2)port utility functions from dracut-functions.sh.

3)The check_resettable function checks if dump target is a resettable
block device. This includes the case where default action dump_to_rootfs
is set.

dc8e283ff5 Deprecate blacklist option
Current blacklist option is different from the option in rhel6. In current
implementation blacklist just means omit the driver, but it should really

to user dracut kernel cmdline rd.driver.blacklist instead.

4b9c868b8d use findmnt instead of blkid in mkdumprd
Previously to_dev_name use blkid to get dev name from dump target,
but blkid can not handle UUID/LABEL with quotes so to_dev_name will
silently fail.

Because we enforce dump target being mounted before creating kdump
initrd, so change to use findmnt is fine. findmnt can handle input
params with quotes.

to_dev_name is not necessary anymore, just remove it.
Also there's another user of it is for checking if the dev is root
or not, here change to use findmnt for this as well.

Tested the rootfs dump, UUID with/without quotes dump.

f21cbb5165 handle readonly mounted filesystem
We need fs dump target being mounted firstly before creating mkdumprd
This is because we want to get the mount options from kernel mountinfo
instead of simply mount it without considering mount options.

To avoid the filesystem being used by something other than kdump we
suggest them to mount it as 'ro', mkdumprd will remount it as 'rw' when
necessary and remount it back to 'ro'

In 2nd kernel kdump will still use 'rw' to mount it though.

Tested local read-only mounted fs dump.

[v1->v2]: improve documentation
          add error handling for `mount -o remount,ro`

4d9bb7face get_ssh_size: use -n to redirect stdin from /dev/null
Resolves: bug 868990

ssh will send local stdin input to remote side, this cause trouble
when we call ssh in the loop of parsing kdump.conf.

Ie. if we specify both 'ssh' and 'core_collector' option in kdump.conf,
and put 'core_collector' behind 'ssh', there will be no chance to
handle 'core_collector' because in get_ssh_size() ssh eat all the later
input of the while loop.

Fix this by use /dev/null as stdin in get_ssh_size().

fca70aadfd improve persistent name handling
For devices with filesystem, udev /dev/disk/by-uuid/* links are usually
reliable. But one exception is multipath devices, child and top layer
device may have same uuid.

As dm devices maintain /dev/mapper/* as persistent names, so converting to
/dev/mapper/* firstly then try by-uuid/* and by-id/*

Also because user know better what's the persistent name we just document well
to suggest user use persistent name in kdump.conf. it's suggested to
to use lvm or multipath canonical names or uuid/label.

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

          remove multi target function
[v5->v6]: vivek: only warning for raw dump of non-makedumpfile core_collector
[v6->v7]: kdumpctl should return 0 when there's no raw target

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
