Rename the subpackage kdump-anaconda-addon to kexec-tools-anaconda-addon
to keep consistency and make fedpkg build happy
Because every time fedpkg builds a new release the package version number
should increase. But kdump-annaconda-addon just keep same version, so let's
rename it to kexec-tools-annaconda-addon here kexec-tools- is a default prefix.
For version let's use default top level version.
At the same time, rename the kdump-anaconda-addon directory name to anaconda-addon
to make it more standard. Using the current data instead of version number as a
surfix of kdump-anaconda-addon tarball just like kexec-tools-po did.

kdump-dep-generator is a systemd generator, used to write out kdump
service dependencies.
Currently it's only useful for ssh dump case. And in ssh dump case, it
writes out a dependency which kdump.service "Wants"
network-online.target:
# ls -l /run/systemd/generator/kdump.service.wants/
[..] network-online.target -> /usr/lib/systemd/system/network-online.target
So that kdump.service will pull in network-online.target and delayed
start until network-online.target is reached.
In the future, we could use generator to write out kdump.service
dynamically and get rid of the static defined kdump.service at all.

[PATCH] memset() in cyclic bitmap initialization introduce segment fault.
We are using memset() to improve performance when creating 1st and 2nd
bitmap. After doing round up the pfn_start and round down pfn_end, it's
possible that pfn_start_roundup is greater than pfn_end_round. A segment
fault could happen in that case because memset is taking roughly the
value of (pfn_end_round << 3 - pfn_start_roundup << 3 ), which is
negative, as its third argument.
So we can skip the memset if start is greater than end. It's safe
because we will set bit for the round up part and also round down part.
Actually this happens on my EFI virtual machine:

[PATCH v5] Support to filter dump for kernels that use CONFIG_SPARSEMEM_VMEMMAP.
Makedumpfile tool fails to filter dump for kernels that are build with
CONFIG_SPARSEMEM_VMEMMAP set, as it fails to do address translations
for vmemmap regions that are mapped out of zone normal. This patch
provides support in makedumpfile to do vmemmap to physical address
translations when they are mapped outside zone normal. Some kernel
symbols are needed in vmcoreinfo for this changes to be effective.
The kernel patch that adds the necessary symbols to vmcoreinfo has
been posted to linuxppc devel mailing list. This patch is influenced
by vmemmap to physical address translation support code in crash tool.
This patch has been tested successfully at all dump filtering levels
on kernels with CONFIG_SPARSEMEM_VMEMMAP set/unset. Also, tested dump
filtering on already filtered vmcores (re-filtering).

Description of Problem:
This is a REGRESSION issue.
At fedora makedumpfile has been updated toward v1.5.4. Unfortunately,
this version fails calculating phys_base on sadump format and then
fails converting vmcore.
x86_64 kernel is relocatable kernel and there can be a gap between
the physical address statically assigned to kernel data and texts
and the address that is really assigned to each object corresponding
to the kernel symbols. The gap is phys_base. makedump calculates the
phys_base in an ad-hoc way that comparing the addresses of some of
occurrences of "Linux kernel" strings in certain range of vmcore.
Resolution:
Fix patch has already been posted in upstream. so just back port.

Description of Problem:
In cyclic mode, makedumpfile recalculates cyclic buffer size as the
largest multiple of the largest block size managed by buddy
allocator, i.e. 4MB, smaller than the cyclic buffer size in order to
enable to process each unit of blocks managed by buddy allocator in
each cycle.
However, makedumpfile does two wrong things in the recalculations:
1) While updating size of cyclic buffer, makedumpfile doesn't update
length of range of cycle in page frame numbers, due to which, if
cyclic buffer size is updated, because cyclic buffer size is always
reduced during udpate, some buffer overrun can happen on the cyclic
buffer. This can cause segmentation violation in the worst case.
2) roundup() is used to calculate bitmap size for maximum block size
managed by buddy allocator, here divideup() is correct, due to
which, although memory filtering is not affected, cyclic buffer size
get too much aligned and less efficient.
Fix patches has already been posted and merged in makedumpfile
development devel branch.

The dumpfile header has this field, which was inherited from
the old "diskdump" facility:
struct disk_dump_header {
...
unsigned int max_mapnr; /* = max_mapnr */
...
and which, among other things, is used by the crash utility as a
delimiter to determine whether a physical address read request is
legitimate. And obviously the field cannot handle PFN values greater
than 32-bits.
The makedumpfile source code does have its own max_mapnr representation
in its DumpInfo structure in "makedumpfile.h":
struct DumpInfo {
...
unsigned long long max_mapnr; /* number of page descriptor */
...
But in its "diskdump_mod.h" file, it carries forward the old diskdump
header format, which has the 32-bit field:
struct disk_dump_header {
...
unsigned int max_mapnr; /* = max_mapnr */
...
And here in "makedumpfile.c", the inadvertent truncation occurs
when the PFN is greater than 32-bits:
int
write_kdump_header(void)
{
...
dh->max_mapnr = info->max_mapnr;
...

Currenty the kexec-tools package contains udev rules for kdump
that reload kdump in case of memory or CPU hotplug:
$ cat /etc/udev/rules.d/98-kexec.rules
SUBSYSTESUBSYSTEM=="cpu", ACTION=="online", PROGRAM="/bin/systemctl try-restart kdump.service"
SUBSYSTEM=="cpu", ACTION=="offline", PROGRAM="/bin/systemctl try-restart kdump.service"
SUBSYSTEM=="memory", ACTION=="add", PROGRAM="/bin/systemctl try-restart kdump.service"
SUBSYSTEM=="memory", ACTION=="remove", PROGRAM="/bin/systemctl try-restart kdump.service"
On other architectures the rules are necessary because the memory
and CPU layout stored in the kdump in-memory ELF header at kdump
load time. Therefore the kdump kernel has to be reloaded each
time when the CPU or memory configuration changes.
This has drawbacks:
1. During kdump reload the system can't be dumped.
2. On systems with many hotplug events (e.g. on s390 with cpuplugd)
this creates significant overhead
The reload is not necessary on s390 because there the ELF header is
created in the 2nd (kdump) kernel. Therefore, to improve things,
remove the rules for s390.

Someone need this for kexec to load memdisk which is smaller then 32k.
kexec-tools-2.0.3-Load-bzImages-smaller-than-32-KiB.patch
bz849650, for efi booting system we need this acpi_rsdp kernel argument
after vivek's secure boot work we maybe need drop this one.
kexec-tools-2.0.3-kdump-pass-acpi_rsdp-to-2nd-kernel-for-efi-booting.patch
Add below two commits from upstream:
1.

vmcore-dmesg: Do not write beyond end of buffer
scan_vmcoreinfo() currently assumes that every vmcoreinfo note line ends
with \n and overwrites new line with \0. But last entry in note, CRASHTIME=
does not end with \n and this leads to corrupting memory as we write beyond
end of buffer.
Normally things were fine but when I added some fields to vmcoreinfo, this
bug started showing and vmcore-dmesg started crashing.
I am planning to send a patch to fix this in kernel but it might be good
idea to handle this case in user space too so that vmcore-dmesg works
fine with cores of older kernels.

vmcore-dmesg: vmcore-dmesg: Make it work with new structured logging format
Now kernel has made kernel logging structured and exsisting vmcore-dmesg
does not work with this new format. Hence kernel version 3.5 is broken. In
3.6 now a kernel patch has been put which exports relevant fields. This
patch parses those fields and makes vmcore-dmesg work with new logging
format.
Currently it does not display log levels or dictionary. I personally think
that log levels are not very useful and it also requires additional kernel
patches so that log levels are not bitfields and relevant information is
exported to user space properly.
Concept of dictionary is new and relevant information is exported. One can
possibly enahnce vmcore-dmesg to also print dictionary contents based on
a user command line option.

dash is be default omited in f17, but we use -o in command line so our omit
modules list will overwrite the system configs, so dash will be installed to
initramfs.
Here avoid install dash by adding it to the '-o' list
Also remove dash dependency from rpm spec

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.

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
ChaoWang: add prefix to dracut files
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
