c894022e9b Remove references to systemd-sysv-convert
Packaging guidelines have been amended to not require systemd for scriptlets,
see https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/#_scriptlets.

The comment duplicates what the macro contains.

systemd-sysv-convert binary was removed in 2013, trying to call it is
unlikely to succeed.

chkconfig binary is provided by the chkconfig package, which is not in
Requires. (And makes little sense to call nowadays anyway.)

6463641935 Add a new hook: 92-crashkernel.install
To track and manage kernel's crashkernel usage by kernel version,
each kernel package will include a crashkernel.default containing the
default `crashkernel=` value of that kernel. So we can use a hook to
update the kernel cmdline of new installed kernel accordingly.

Put it after all other grub boot loader setup hooks, so it can simply
call grubby to modify the kernel cmdline.

fa9201b240 fadump: isolate fadump initramfs image within the default one
In case of fadump, the initramfs image has to be built to boot into
the production environment as well as to offload the active crash dump
to the specified dump target (for boot after crash). As the same image
would be used for both boot scenarios, it could not be built optimally
while accommodating both cases.

Use --include to include the initramfs image built for offloading
active crash dump to the specified dump target. Also, introduce a new
out-of-tree dracut module (99zz-fadumpinit) that installs a customized
init program while moving the default /init to /init.dracut. This
customized init program is leveraged to isolate fadump image within
the default initramfs image by kicking off default boot process
(exec /init.dracut) for regular boot scenario and activating fadump
initramfs image, if the system is booting after a crash.

If squash is available, ensure default initramfs image is also built
with squash module to reduce memory consumption in capture kernel.

50bb8b701f check for invalid physical address of /proc/kcore when making ELF dumpfile
Backport from upstream.

commit 9a6f589d99dcef114c89fde992157f5467028c8f

    [PATCH] check for invalid physical address of /proc/kcore when making ELF dumpfile

    Previously when executing makedumpfile with -E option against
    /proc/kcore, makedumpfile will fail:

      # makedumpfile -E -d 31 /proc/kcore kcore.dump
      ...
      write_elf_load_segment: Can't convert physaddr(ffffffffffffffff) to an offset.

      makedumpfile Failed.

    It's because /proc/kcore contains PT_LOAD program headers which have
    physaddr (0xffffffffffffffff).  With -E option, makedumpfile will
    try to convert the physaddr to an offset and fails.

    Skip the PT_LOAD program headers which have such physaddr.

    [PATCH] check for invalid physical address of /proc/kcore when finding max_paddr

    Kernel commit 464920104bf7adac12722035bfefb3d772eb04d8 ("/proc/kcore:
    update physical address for kcore ram and text") sets an invalid paddr

    makedumpfile uses max_paddr to calculate the number of sections for
    sparse memory model thus wrong number is obtained based on max_paddr
    (-1).  This error could lead to the failure of copying /proc/kcore
    for RHEL-8.5 on ppc64le machine [1]:

      $ makedumpfile /proc/kcore vmcore1
      get_mem_section: Could not validate mem_section.
      get_mm_sparsemem: Can't get the address of mem_section.

      makedumpfile Failed.

    Let's check if the phys_start of the segment is a valid physical
    address to fix this problem.

Backport from upstream.

commit 646456862df8926ba10dd7330abf3bf0f887e1b6
Author: Kazuhito Hagio <k-hagio-ab@nec.com>
Date:   Wed May 26 14:31:26 2021 +0900

    [PATCH] Increase SECTION_MAP_LAST_BIT to 5

    * Required for kernel 5.12

    Kernel commit 1f90a3477df3 ("mm: teach pfn_to_online_page() about
    ZONE_DEVICE section collisions") added a section flag
    (SECTION_TAINT_ZONE_DEVICE) and causes makedumpfile an error on
    some machines like this:

      __vtop4_x86_64: Can't get a valid pmd_pte.
      readmem: Can't convert a virtual address(ffffe2bdc2000000) to physical address.
      readmem: type_addr: 0, addr:ffffe2bdc2000000, size:32768
      __exclude_unnecessary_pages: Can't read the buffer of struct page.
      create_2nd_bitmap: Can't exclude unnecessary pages.

    Increase SECTION_MAP_LAST_BIT to 5 to fix this.  The bit had not
    been used until the change, so we can just increase the value.

a2306346bc Remove the kdump error handler isolation wrapper
The wrapper is introduced in commit 002337c, according to the commit
message, the only usage of the wrapper is when dracut-initqueue calls
"systemctl start emergency" directly. In that case, emergency
is started, but not in a isolation mode, which means dracut-initqueue
is still running. On the other hand, emergency will call
"systemctl start dracut-initqueue" again when default action is dump_to_rootfs.

systemd would block on the last dracut-initqueue, waiting for the first
instance to exit, which leaves us hang.

In previous commit we added initqueue status detect in dump_to_rootfs,
so now even without the wrapper, it will not hang.

And actually, previously, with the wrapper, emergency might still hang
for like 30s. When dracut called emergency service because initqueue
timed out, dump_to_rootfs will try start initqueue again and timeout
again. Now with the wrapper removed, we can avoid these two kinds of
hangs, bacause without the isolation we can detect initqueue service
status correctly in such case.

Also remove the invalid header comments in service file, the service
is not part of systemd code. And sync the service spec with dracut.

475e33030b Make dracut-squash required for kexec-tools
This patch reverts commit "Make dracut-squash a weak dep".

Although kexec-tools can work without dracut-squash, it is essential
for kdump to run properly in cases [1][2] where minimal amount of memory
consumption is expected. Thus dracut-squash is needed for it.

    [PATCH] Show write byte size in report messages

    Show write byte size in report messages.  This value can be different
    from the size of the actual file because of some holes on dumpfile
    data structure.

      $ makedumpfile --show-stats -l -d 1 vmcore dump.ld1
      ...
      Total pages     : 0x0000000000080000

      ...
      # ls -l dump.ld1
      -rw------- 1 root root 377691573 Feb  4 16:28 dump.ld1

    Note that this value should not be used with /proc/kcore to determine
    how much disk space is needed for crash dump, because the real memory
    usage when a crash occurs can vary widely.

support only when available, but the spec file hard requires it. Demote
it to a weak dep to truly make it optional.

This caters to environments which strive to stay minimal, like FCOS and
RHCOS. See https://github.com/coreos/fedora-coreos-config/pull/708 for
details.

8bef2d943b kexec-tools.spec: make the existence of pre.d and post.d mandatory
If the directory /etc/kdump/pre.d is optional, then it is hard
to tell between the following cases:
  -1. no directory "/etc/kdump/pre.d"
  -2. "rm -rf /etc/kdump/pre.d", which removes all scripts under pre.d
For the second case, kdump.img should be rebuilt.

To bail out from this corner case, always creating pre.d and post.d
during rpm installation.

476a2b50f6 makedumpfile: Introduce --check-params option
Backport from the upstream makedumpfile devel branch.

commit 989152e113bfcb4fbfbad6f3aed6f43be4455919
Author: Kazuhito Hagio <k-hagio-ab@nec.com>
Date:   Tue Feb 25 16:04:55 2020 -0500

    [PATCH] Introduce --check-params option

    Currently it's difficult to check whether a makedumpfile command-line
    is valid or not without an actual panic.  This is inefficient and if
    a wrong configuration is not tested, you will miss the vmcore when an
    actual panic occurs.

    In order for kdump facilities like kexec-tools to be able to check
    the specified command-line parameters in advance, introduce the
    --check-params option that only checks them and exits immediately.

cee618593c Add a hook to wait for kdump target in initqueue
The dracut initqueue may quit immediately and won't trigger any hook if
there is no "finished" hook still pending (finished hook will be deleted
once it return 0).

This issue start to appear with latest dracut, latest dracut use
network-manager to configure the network,
network-manager module only install "settled" hook, and we didn't
install any other hook. So NFS/SSH dump will fail. iSCSI dump works
because dracut iscsi module will install a "finished" hook to detect if
the iscsi target is up.

So for NFS/SSH we keep initqueue running until the host successfully get
a valid IP address, which means the network is ready.

a0db00d575 makedumpfile: Fix inconsistent return value from find_vmemmap()
Backport from the makedumpfile devel branch in upstream.

commit 8425342a52b23d462f10bceeeb1c8a3a43d56bf0
Author: Kazuhito Hagio <k-hagio@ab.jp.nec.com>
Date:   Fri Sep 6 09:50:34 2019 -0400

    [PATCH] Fix inconsistent return value from find_vmemmap()

    When -e option is given, the find_vmemmap() returns FAILED(1) if
    it failed on x86_64, but on architectures other than that, it is
    stub_false() and returns FALSE(0).

              if (info->flag_excludevm) {
                      if (find_vmemmap() == FAILED) {
                              ERRMSG("Can't find vmemmap pages\n");

      #define find_vmemmap()          stub_false()

    As a result, on the architectures other than x86_64, the -e option
    does some unnecessary processing with no effect, and marks the dump
    DUMP_DH_EXCLUDED_VMEMMAP unexpectedly.

    Also, the functions for the -e option return COMPLETED or FAILED,
    which are for command return value, not for function return value.

    So let's fix the issue by following the common style that returns
    TRUE or FALSE, and avoid confusion.

Backport from the makedumpfile devel branch in upstream.

commit b461971bfac0f193a0c274c3b657d158e07d4995
Author: Kazuhito Hagio <k-hagio@ab.jp.nec.com>
Date:   Thu Aug 29 14:51:56 2019 -0400

    [PATCH] Fix exclusion range in find_vmemmap_pages()

    In the function, since pfn ranges are literally start and end, not start
    and end+1, if the struct page of endpfn is at the last in a vmemmap page,
    the vmemmap page is dropped by the following code, and not excluded.

        npfns_offset = endpfn - vmapp->rep_pfn_start;
        vmemmap_offset = npfns_offset * size_table.page;
        // round down to page boundary
        vmemmap_offset -= (vmemmap_offset % pagesize);

    We can use (endpfn+1) here to fix.

Author: Kazuhito Hagio <k-hagio@ab.jp.nec.com>
Date:   Thu Aug 29 12:26:34 2019 -0400

    [PATCH] x86_64: Fix incorrect exclusion by -e option with KASLR

    The -e option uses info->vmemmap_start for creating a table to determine
    the positions of page structures that should be excluded, but it is a
    hardcoded value even with KASLR-enabled vmcore.  As a result, the option
    excludes incorrect pages from it.

    To fix this, get the vmemmap start address from info->mem_map_data.

    kernel commit 326e1b8f83a4 ("mm/sparsemem: introduce a SECTION_IS_EARLY
    flag") added the flag to mem_section->section_mem_map value, and it caused
    makedumpfile an error like the following:

      __exclude_unnecessary_pages: Can't read the buffer of struct page.
      create_2nd_bitmap: Can't exclude unnecessary pages.

    To fix this, SECTION_MAP_LAST_BIT needs to be updated. The bit has not
    been used until the addition, so we can just increase the value.

    So get NUMBER(sme_mask) from vmcoreinfo, which stores the value of
    the C-bit position, and drop it to obtain the true physical address.

3001788f4c Add aarch64 specific kdump.sysconfig and use 'nr_cpus' instead of 'maxcpus'
'maxcpus' setting normally don't work on several kdump enabled systems
due to a known udev issue.

Currently the fedora kdump configuration is set as the following on the
aarch64 systems:

 # cat /etc/sysconfig/kdump
<..snip..>
  # This variable lets us append arguments to the current kdump
  # commandline after processed by KDUMP_COMMANDLINE_REMOVE
  # KDUMP_COMMANDLINE_APPEND="irqpoll maxcpus=1 reset_devices"
<..snip..>

Since the 'maxcpus' setting doesn't limit the number of SMP CPUs,
so the kdump kernel still boots with all CPUs available on the system.
For e.g on the qualcomm amberwing its 46 CPUs:

  # lscpu
Architecture:        aarch64
Byte Order:          Little Endian
CPU(s):              46
On-line CPU(s) list: 0-45
Thread(s) per core:  1
Core(s) per socket:  46
Socket(s):           1
NUMA node(s):        1
Vendor ID:           Qualcomm
Model:               1
Model name:          Falkor
Stepping:            0x0
CPU max MHz:         2600.0000
CPU min MHz:         600.0000
BogoMIPS:            40.00
L1d cache:           32K
L1i cache:           64K
L2 cache:            512K
L3 cache:            58880K
NUMA node0 CPU(s):   0-45
Flags:               fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid asimdrdm

This causes the memory consumption in the kdump kernel to swell up and
we can end up having OOM issues in the kdump kernel boot.

Whereas if we use 'nr_cpus=1' in the bootargs, the number of SMP CPUs in
the kdump kernel get limited to 1.

The 'swiotlb=noforce' setting in bootargs provide us extra guarding, to
ensure the crash kernel size requirements do not swell on systems
which support swiotlb.

With the above settings, crashkernel boots properly (without OOM) on all

a585f981bd kexec.rules: create dedicated udev rules for ppc64
On powerpc, after hot add cpu and trigger crash on the hot-added cpu, the
kdump kernel hangs after "I'm in purgatory".

The current udev rules expects the dtb to be rebuit on cpu add/remove event.
But since powerpc does not follow the standard cpu hot add framework, it
only ejects online/offline event to user space when cpu is hot
added/removed, instead of add/remove event.  Pingfan tried fixing that but
it didn't please the maintainer as it breaks some old userspace tools.

Due to the failure of dtb's rebuilding, KDump kernel fails to get the
'boot_cpuid' and eventually fails to boot [see early_init_dt_scan_cpus() in
arch/powerpc/kernel/prom.c file] if system crashes on hot-added CPU.

Work around it by changing udev rules on powerpc to onlne/offline.

As for offline message, it is even useless on powerpc, and can be dropped.
See the explain: On powerpc, /sys/devices/system/cpu/cpuX nodes are present
for all "possible", irrespective of whether a CPU is hot-added/removed.
crash_notes are already built for all /sys/devices/system/cpu/cpuX nodes and
these nodes are present for all "possible" CPUs
(online/offline/could-be-hot-removed/could-be-hot-added)

2fc7312546 Enable building with hardening flags
Backport the patches required to make the hardening build flags work with
kexec-tools and makedumpfile, and enabld hardening flags in spec file.
This will make the pacakge pass all warnings for kexec and makedumpfile
reported by annocheck.

Didn't find any issue with basic tests with kexec and makedumpfile.
