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.

References: bsc#1108255

Git-commit: f46c26fcf879f368726acf650c43eacde909dc9d
If a crash happens while a balance operation is being performed on a
target btrfs filesystem, then this balance operation is resumed in
the kdump environment, which is not desirable. Skip it by adding a
'skip_balance' mount option to the kdump initrd.

Git-commit: e32374a88bb3b1dc0c5f493d6c1966558d996c4f
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: c4484c33a5b228d4a1ebe7c99f14c3b7f38f34ef
All existing routes are now added through the rd.route= dracut
parameter. However, this includes routes that need not or should not
be added explicitly (e.g. installed automatically by the kernel or
dynamically by a routing daemon).
If possible, use wicked to get configured routes. If not, use the
routing protocol identifier to limit the list.

Subject: [PATCH] kdump: activate udev rules late during boot
The kdump udev rule is very broad in scope and may slow down
booting strongly, especially during the coldplug phase where
"add" events for lots of CPU and memory devices have to be
processed. Therefore, activate this rule (which has the purpose
to support real hotplug rather than coldplug) late in the boot
sequence.

References: bsc#1091186
Upstream: merged
Git-commit: ac14396b33a7d507a65999aa7f70668f9cd15e8e
During boot, custom services like kdump-save.service run in parallel
with other generic initrd services up until initrd.target. However,
a reload from real root may change the dependency graph in a way
that prevents kdump-save.service from finishing. Since kdump needs
only the explicitly listed mount points, boot process may pause
while the dump is being saved. In fact, it is preferable to do so,
lest other processes interfere with kdump itself in the restricted
environment.

Currently, the udev rules written in kdump package only support reloading
kdump on memory/cpu hot add/remove operation. But this is needed as much
for FADump as well. The rules were not updated to support fadump owing to
lack of support in the kernel for re-registering FADump. This support is
now added to kernel with commit 0823c68b054b ("powerpc/fadump: re-register
firmware-assisted dump if already registered"). Update kdump udev rules
to load fadump on memory/cpu DLPAR operations.

Since commit 9a3764178a91 ("Blacklist unneeded multipath devices")
multipath devices that are not needed while capturing dump were
blacklisted. This reduces the memory requirements on kdump kernel.
But when this optimization is added to default initrd by including
dump capturing support for FADump, it is observed to mess with the
initialization of such blacklisted multipath devices while booting
the production kernel. To avoid such issues, use this optimization
only while booting a capture kernel.

Subject: fadump: fix network bring up issue during default boot
References: bsc#1101730
Upstream: merged
Git-commit: 0ad221c8a81ee812b3afec6a9c873bd5bd1c228b
If ssh is used for dump target, kdump module enforces bringing up the
network (rd.neednet=1). If bringing up the network fails, it drops to
emergency shell. This sounds ok for a kdump kernel as it's only job is
to save dump to the specified dump target and reboot. But in case of
FADump, kdump module, which adds dump capturing support in the initrd,
is added to the regular initrd. If network bring up fails, production
kernel also falls to emergency shell while booting. Considering this
requirement has no relevance in booting a production kerne, that could
have been avoided. Fix it here by enforcing rd.neednet=1 only while
booting a capture kernel.

Creation of symbolic link to kdump-save.service will fail if the directory
doesn't exists, and dump will not be captured because kdump-save.service is
never started.
The user will see the rescue mode prompt when the kernel crashed because
systemd will proceed to initrd-switch-root, which will fail (thus triggering
rescue mode) because kdump initrd does not setup /sysroot properly.

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.

References: bsc#1133407, LTC#176111
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.

Subject: Recover from missing CRASHTIME= in VMCOREINFO
References: bsc#1112387
Upstream: merged
Git-commit: 0bc94943a1df4d923aa20b9bd1ff01ed2e49d70c
CRASHTIME= may be missing in Xen Dom0 dumps.
Vmcoreinfo::getLLongValue throws an exception in that case, but then
OSRELEASE will not even be attempted. Consequently, kernel and
system map files are not copied, producing the following message:
INFO: Don't copy the kernel and System.map because of missing crash kernel release.

Subject: Remove noefi and acpi_rsdp for EFI firmware
References: bsc#1123940
Upstream: merged
Git-commit: 3ea13723f93cc22d163f1f1c8e64ccef3fa32471
The noefi and acpi_rsdp can be removed because kernel passes necessary
EFI data for kexec via setup_data since 1fec05336 patch be introduced
in v3.14 kernel. (bsc#1098210)
On the other hand, the MOK (machine owner key) doesn't work with noefi.
It causes that third-party signed kernel modules can not be loaded by
crash kernel. Crash kernel can provide EFI runtime services for loading
MOK after noefi be removed. (bsc#1123940)
The kdump without noefi has been tested on Huawei Kunlun, Intel
minnowboard and KVM-OVMF.

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.

Subject: Turn off NUMA in the kdump kernel
References: bsc#1109784, bsc#1102609
Upstream: merged
Git-commit: 4c0e78b9923f0dbba3ad1bacc2336d91f7b520e5
On NUMA systems, the crashkernel reserved region may get allocated
on a different node than the low region (memory below 4G). With NUMA
optimization turned on, the kernel will prefer node-local pages for
all page allocations, which may unnecessarily deplete the DMA and
DMA32 regions with data that could be allocated from the Normal
zone (which is on a remote node).
It makes little sense to address this corner case in the memory
management system, because nobody would build a machine with almost
all memory on a remote node. So, instead, let's turn off NUMA for
kdump and accept the potential performance hit.
