Subject: Add ":force" option to KDUMP_NETCONFIG
References: bsc#1108919
Upstream: merged
Git-commit 4e112a28055a57dbcdf9a72c4bdcf586296ec81a
Make it possible to force network setup in kdump initrd by adding a
":force" suffix to KDUMP_NETCONFIG. This is needed to configure
fence_kdump.

Strictly differentiate between the interface name as seen during
dracut execution and at boot time (in initrd environment).
Most importantly, it is necessary to store both names for generating
qeth udev rules.

Git-commit 83e48556428339668e6f23e1dccc0196a52d1b68
If the system continues to boot, kdump mount points must be
unmounted before switching to the system root. Otherwise, some
filesystems may remain mounted under the now-unavailable initrd
root, keeping the underlying devices busy during system shutdown.

Subject: Improve the handling of NSS
References: bsc#1021846
Upstream: merged
Git-commit 598d7517ccbbf29dc51e0a9c14146722d2324731
The current code mostly works, but can be improved in two ways:
1. Only the 'hosts' database is really needed in the kdump
environment, and its settings should be copied from the running
system. The openSSH client also needs 'passwd' (and maybe
'group'), but it is not necessary to handle fancy setups (such
as NIS or AD). The client merely requires that UID 0 can be
translated to a user name. The 'file' service is more than
sufficient for that purpose.
2. The NSS configuration file may not contain configuration of all
categories. If configuration for a given category is missing,
glibc will use a default setting, but kdump will not install
the corresponding modules. Fix it by adding the glibc default
to the configuration file explicitly if needed.

Git-commit: d1c4f630f0da0bf43928e3c975f02e832b2df50f
Skipping reload after a CPU goes offline does not have any adverse
impact, as /sys/devices/system/cpu/cpuX nodes are present for all
"possible" CPUs on PPC64.
The udev rule for CPU online operation is still needed. If reload
is skipped and the system crashes on a hot-added CPU, the kdump
kernel fails to get the 'boot_cpuid' after a hot plug and
eventually fails (see early_init_dt_scan_cpus() in
arch/powerpc/kernel/prom.c file).

Subject: Prefer by-path and device-mapper aliases over kernel names
References: bsc#1101149, LTC#168532
Upsream: merged
Git-commit: f153c9ac3f1baf8d1cf66c901b41f7bff19ff528
Mounting by kernel names (e.g. /dev/sda) is generally broken, since
these names are allocated dynamically by the kernel and may change
after a panic kexec. This issue can be usually avoided by using a
more stable tag in /etc/fstab (e.g. UUID=xyz).
However, there are supported ways to mount a filesystem with no
corresponding line in /etc/fstab, and kdump uses /proc/mounts as
fallback. This file shows the block device using the name that was
given as argument to the mount syscall. This name is usually
translated to the kernel name by libblkid(3). As a result, it does
not reflect the original intention, e.g.:
ezekiel:~ # mount UUID=9A4D-9B2B /mnt/data/
ezekiel:~ # grep /mnt/data /proc/mounts
/dev/sda /mnt/data vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 0
ezekiel:~ # grep /mnt/data /proc/self/mountinfo
187 94 8:0 / /mnt/data rw,relatime shared:56 - vfat /dev/sda rw,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro
As the original intention cannot be recovered, it is probably
better to prefer the by-path alias. The semantic of this alias is
closest to the traditional UNIX use of raw block device names: it's
always the drive attached to a known physical connector, regardless
of which medium is inserted.

Subject: Preserve white space when removing kernel command line options
References: bsc#1117652
Upstream: merged
Git-commit: 23d593b54a9c97a204ea7412e53c60d3d3852cab
The function was originally designed to remove unwanted options
from the panic kernel command line. It is now also used to check
whether the current command line contains a fadump option or not,
but the check is broken, because remove_from_commandline() may
change the amount (and type) of white space. For example, it
always adds an extra space if the original string ends with a
space.
Modify the function to copy original separators verbatim, except
that any white space preceding the removed option is removed.

With FADUMP, the same initrd is used for saving a dump and for
normal boot. It is not necessary to mount kdump-related filesystems
on a normal boot, so let's add a systemd condition.
