Patch-mainline: v0.8.17
Git-commit: 51a68c31497d1895602d5c6851e23a9027d9675d
Currently, we are default'ing to "SPILT" as well as multi-threading
when KDUMPTOOL_FLAGS="". Ensure split is enabled only when it is set
explicitly with KDUMPTOOL_FLAGS="SPLIT".

Subject: [PATCH] Don't exit even if initrd is not built
References: bsc#1047781
Patch-mainline: v0.8.17
Git-commit: 086068496508087b68029ae31a93ed5d3e4ac2cb
In case where there is no change in kdump config, new initrd won't be
built. Restarting kdump.service in above case exits as initrd is same
as older. As control doesn't proceed further, it fails to enable dump
configuration.
This patch fixes above mentioned issue by proceeding further and enabling
dump configuration.

Subject: [PATCH] Limit kdump cpus to number provided by config
References: bsc#1036223, bsc#1068234
Patch-mainline: v0.8.17
Git-commit: 4fc281692f5bef9a23c603a37e7a1bc30ee0a855
Current piece of code doesn't verify number of kdump cpus provided in
config with number of online cpus and uses all online cpus as kdump cpus
even if KDUMP_CPUS are provided in the config.
Current code:
If online cpus = 5 and KDUMP_CPUS = 2 , then current piece of code
considers all online cpus as kdump cpus which is 5 but as KDUMP_CPUS
is provided as 2, we should restrict makedumpfile to use KDUMP_CPUS
which is 2 in this case.
In case of kdump, as we use maxcpus=1 and hence online cpus remains 1
but in case of fadump all cpus are online and even after providing
KDUMP_CPUS=1 in config, it consider all online cpus as kdump cpus.
This patch fixes above issue by verifying KDUMP_CPUS with online cpus.
If KDUMP_CPUS > online cpus then only use online cpus as kdump
cpus else use KDUMP_CPUS as dump cpus.

Subject: Handle additional mounts in the kdump dracut module
References: bsc#1089917
Upstream: merged
Git-commit: bd3cc31f3b91e81e6acc00f314142bbda9ace495
This change is needed to fix FADUMP, because in that case the kdump
initrd is also used during normal boot, so it can get overwritten
with an invocation of "mkinitrd".
Currently, dracut does not provide an API to add more mounts from a
module, so part of the logic which sets up host devices and
filesystem mappings must be copied to the kdump module.
The approach is not clean, but probably still better than passing
some variables from mkdumprd to the kdump dracut module through
environment variables, which was done before. Yes, this means that
the ugly export/import functions can be removed and forgotten.

Timezone data is not always copied automatically by dracut. In fact,
the code which does that is SUSE-specific, see bsc#830060, or SUSE
patch 0020-00warpclock-Set-correct-timezone.patch.
Even with the above patch, localtime is not copied on s390(x).

Currently, kexec_load(2) is attempted only if kexec_file_load(2) is
unavailable. However, kexec_file_load(2) may also fail for other
reasons (e.g. missing kernel signature). It makes sense to try the
older syscall in that case.

References: bsc#976864
Upstream: v0.8.17
Git-commit: a532a27d0bb7f69fbf89527fb02e8434fdafa147
In SLES 12 SP2, systemd-fstab-generator no longer ignores non-device
root mounts, so it tries to run an actual mount command for root=kdump.
This fails, of course, because "kdump" is not mountable.
To solve this, pass "rootflags=bind" to the panic kernel, so systemd
can create a (bogus) bind mount and be happy.
See also kdump-root-parameter.patch.

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.

Subject: bootloader: Filter out KDUMPTOOL_FLAGS
References: bsc#1072584
Upstream: merged
Git-commit: df216d1815eae7e8c4b139e0676696de4dc447d2
The bootloader update filters out all parameters starting with
KDUMP_, MAKEDUMPFILE_ or fadump. KDUMPTOOL_FLAGS does not match, so
it is not removed and consequently multiple instances may appear on
the command line.

Freeing fadump memory can take a long time and doing it when we are going to
reboot anyway is pointless.
In bsc#1034169 a kernel oops is triggered by freeing fadump memory killing
save_dump.sh and preventing the reboot requested by the user from happening
entirely.
Avoid the issue and speed up reboot by not freeing fadump memory when reboot is
requested.

When using NPIV with LUN autoscan, dracut does not save the port and
LUN information. However, LUN autoscan is always disabled in kdump
environment, so the LUNs will never appear.
To fix this case, the full information must be saved explicitly in a
kdump initrd.

Git-commit: 11d36a645ab99c9805f9fa3ca9eabce3aa2a9418
For NFS, the parent directory of the target must be mounted, because
the target directory itself does not exist yet.
For this to work, split the target path to directory (i.e. parent
directory) and basename. Then construct a unique mount point from the
host name and the parent directory, and finally append the base name
again to form a subdirectory in the target (to be created by the file
transfer method).

Subject: Fix kdump-related services
References: bsc#1021484
Upstreams: v0.8.17
Git-commit: 168b7bfeb992594df08c7e4020ac34f1d9a825bb
kdump.service should be the "big switch" to turn kdump on and off. We
can achieve this by adding an Also= directive.
kdump-early.service is merely a way to load a kdump kernel a early
during the boot process if and only if the kdumprd already exists (e.g.
from a previous boot). There may be some use cases for enabling only
the early service without kdump.service.
OTOH, it is not an error if the initrd is not found during the early
stages. This is indicated by exit code 6 (originally conforming to LSB
"program not configured" exit code).

The "--num-threads" and "--split" makedumpfile options are mutually
exclusive. Before multithreading was implemented, "--split" was the
only way to use any additional CPUs. It makes more sense to use
multithreading by default.
To use "--split", the SPLIT flag can be specified.

Upstream: merged
Git-commit: 0724bcc8220bf2bd4a3598185dcd5ec7e9e5fe47
The kASLR algorithm may decide to place the kernel into low memory,
which does not leave enough space for SWIOTLB, and dumping fails
later on. Since the kdump environment does not run any exploitable
services, kASLR can be safely disabled.
Note that kexec already avoids the low memory reservation when
finding a suitable location for the kernel, initrd and other data.

Subject: IPv6 setup: pass address prefix in separate dracut arg
References: bsc#1062026
Upstream: merged
Git-commit: c6fb83e6ebc310c615c145962f71b3f6f4819e88
Dracut distinguishes IPv6 addresses by bracket enclosing [1] so pass an
IPv6 address as such. The address prefix is passed separately through
netmask dracut argument (that is a slight misnomer as dracut just
propagates that value to iproute2 tools [2] which interpret it as
decimal number of prefix bits).

Subject: Pre-generate kdump mount units
References: bsc#942895
Upstream: v0.8.17
Git-commit: a7e47cdf9cb7db385bc30fce59abce1dc2b5cc11
SUSE version of dracut intentionally modifies the initrd to run
systemd-fstab-generator only after the root filesystem is mounted.
This breaks kdump-save.service, because mount units for /kdump/*
do not yet exist when kdump needs them.
Solve this by pre-generating the required mount units in the primary
system, so kdump no longer depends on running the fstab generator in
initrd context.
Note that I had to write a temporary /etc/fstab, because dracut
creates this file only after all modules have been processed.

When kdump is saved to / (ie /var is not separate filesystem) /kdump/mnt0 is
bind mount of readonly /sysroot. Due to mount bug "mount /kdump/mnt0 -o
remount,rw" does nothing.
Remount the device by hand with "mount none /kdump/mnt0 -o remount,rw" which
avoids the bug.

It would be nicer to strip the brackets in URLParser and work with a
plain IPv6 as hostname. However, since we pass that value to callees
that expect bracketed form (e.g. NFS mount) we invert the convention and
keep the bracketed version and use bare IPv6 to feed getaddrinfo only.

Use the same approach as with IPv6, i.e. configure it only when any
IPv4 addresses are present.

Subject: Try both kexec_load(2) and kexec_file_load(2)
References: bsc#951144
Upstream: merged
Git-commit: ab9c22489ef7627e3f0ad67f46ea19e8d401d044
The logic in load.sh will use kexec_load first. If kexec_load fails
or is blocked by kernel, then it will try kexec_load_file on
x86_64.

Subject: Use bus id to identify qeth devices
References: bsc#1085617
Upstream: merged
Git-commit: 5c608e4d8adf57e66ce85ec62bf59887e6b860e7
QETH devices may not have a stable MAC address, so dracut's ifname=
parameter is not useful. The device's bus ID is stable, but there
is (currently) no support in dracut, so a custom udev rule must be
generated instead.
