    s390: add support for --reuse-cmdline

    --reuse-cmdline reads the command line of the currently
    running kernel from /proc/cmdline and uses that for the
    kernel that should be kexec'd.

    add slurp_proc_file()

    slurp_file() cannot be used to read proc files, as they are returning
    a size of zero in stat(). Add a function slurp_proc_file() which is
    similar to slurp_file(), but doesn't require the size of the file to
    be known.

    s390: add variable command line size

    Newer s390 kernels support a command line size longer than 896
    bytes. Such kernels contain a new member in the parameter area,
    which might be utilized by tools like kexec. Older kernels have
    the location initialized to zero, so we check whether there's a
    non-zero number present and use that. If there isn't, we fallback
    to the legacy command line size of 896 bytes.

    util_lib/elf_info: harden parsing of printk buffer

    The old printk mechanism (> v3.5.0 and < v5.10.0) had a fixed size
    buffer (log_buf) that contains all messages. The location for the next
    message is stored in log_next_idx. In case the log_buf runs full
    log_next_idx wraps around and starts overwriting old messages at the
    beginning of the buffer. The wraparound is denoted by a message with
    msg->len == 0.

    Following the behavior described above blindly is dangerous as e.g. a
    memory corruption could overwrite (parts of) the log_buf. If the
    corruption adds a message with msg->len == 0 this leads to an endless
    loop when dumping the dmesg. Fix this by verifying that not wrapped
    around before when it encounters a message with msg->len == 0.

    While at it also verify that the index is within the log_buf and thus
    guard against corruptions with msg->len != 0.

    The same bug has been reported and fixed in makedumpfile [1].

    [PATCH] print error when reading with unsupported compression

    Currently makedumpfile only checks if the required compression algorithm
    was enabled during build when compressing a dump but not when reading
    from one. This can lead to situations where, one version of makedumpfile
    creates the dump using a compression algorithm an other version of
    makedumpfile doesn't support. When the second version now tries to, e.g.
    extract the dmesg from the dump it will fail with an error similar to

      # makedumpfile --dump-dmesg vmcore dmesg.txt
      __vtop4_x86_64: Can't get a valid pgd.
      readmem: Can't convert a virtual address(ffffffff92e18284) to physical address.
      readmem: type_addr: 0, addr:ffffffff92e18284, size:390
      check_release: Can't get the address of system_utsname.

      makedumpfile Failed.

    That's because readpage_kdump_compressed{_parallel} does not return
    with an error if the page it is trying to read is compressed with an
    unsupported compression algorithm. Thus readmem copies random data from
    the (uninitialized) cachebuf to its caller and thus causing the error
    above.

    Fix this by checking if the required compression algorithm is supported
    in readpage_kdump_compressed{_parallel} and print a proper error message
    if it isn't.

    [PATCH v2 1/3] add generic cycle detection

    In order to work makedumpfile needs to interpret data read from the
    dump. This can cause problems as the data from the dump cannot be
    trusted (otherwise the kernel wouldn't have panicked in the first
    place). This also means that every loop which stop condition depend on
    data read from the dump has a chance to loop forever. Thus add a generic
    cycle detection mechanism that allows to detect and handle such
    situations appropriately.

    For cycle detection use Brent's algorithm [1] as it has constant memory
    usage. With this it can also be used in the kdump kernel without the
    danger that it runs oom when iterating large data structures.
    Furthermore it only depends on some pointer arithmetic. Thus the
    performance impact (as long as no cycle was detected) should be
    comparatively small.

    [PATCH] sadump, kaslr: fix failure of calculating kaslr_offset

    On kernels v5.8 or later, makedumpfile fails for memory dumps in the
    sadump-related formats as follows:

        # makedumpfile -f -l -d 31 -x ./vmlinux /dev/sdd4 /root/vmcore-ld31
        __vtop4_x86_64: Can't get a valid pud_pte.
        ...110 lines of the same message...
        __vtop4_x86_64: Can't get a valid pud_pte.
        calc_kaslr_offset: failed to calculate kaslr_offset and phys_base; default to 0
        readmem: type_addr: 1, addr:ffffffff85411858, size:8
        __vtop4_x86_64: Can't get pgd (page_dir:ffffffff85411858).
        readmem: Can't convert a virtual address(ffffffff059be980) to physical address.
        readmem: type_addr: 0, addr:ffffffff059be980, size:1024
        cpu_online_mask_init: Can't read cpu_online_mask memory.

        makedumpfile Failed.

    This is caused by the kernel commit 9d06c4027f21 ("x86/entry: Convert
    Divide Error to IDTENTRY") that renamed divide_error to
    asm_exc_divide_error, breaking logic for calculating kaslr offset.

    Fix this by adding initialization of asm_exc_divide_error.

06b51aac41 update kernel crashkernel in posttrans RPM scriptlet when updating kexec-tools
Resolves: bz2051822

    update kernel crashkernel in posttrans RPM scriptlet when updating kexec-tools

    When doing in-place upgrading using leapp on x86_64, kdumpcl can't
    acquire instance lock when running in %post RPM scriplet on x86_64,
      localhost upgrade[1306]: /bin/kdumpctl: line 49: /var/lock/kdump: No such file or directory
      localhost upgrade[1306]: kdump: Create file lock failed

    and running "touch /var/lock/dkump" also fails with
    "No such file or directory". Thus kdumpctl can't be run in %post
    scriptlet. But kdumpctl can be run in %posttrans RPM scriplet.

    Besides, it's better to update crashkernel after the kernel has been
    updated. So let's update kernel crashkernel in the %posttrans
    scriptlet which will be run in the end of a transaction i.e. after
    the kernel has been updated.

    Note for %posttrans scriptlet, "$1 == 1" means both installing a new
    package and upgrading a package.

    s390: handle R_390_PLT32DBL reloc entries in machine_apply_elf_rel()

    Starting with gcc 11.3, the C compiler will generate PLT-relative function
    calls even if they are local and do not require it. Later on during linking,
    the linker will replace all PLT-relative calls to local functions with
    PC-relative ones. Unfortunately, the purgatory code of kexec/kdump is
    not being linked as a regular executable or shared library would have been,
    and therefore, all PLT-relative addresses remain in the generated purgatory
    object code unresolved. This in turn lets kexec-tools fail with
    "Unknown rela relocation: 0x14 0x73c0901c" for such relocation types.

    Furthermore, the clang C compiler has always behaved like described above
    and this commit should fix the purgatory code built with the latter.

    Because the purgatory code is no regular executable or shared library,
    contains only calls to local functions and has no PLT, all R_390_PLT32DBL
    relocation entries can be resolved just like a R_390_PC32DBL one.

    spec: add hostname.rpm into Recommends list

    kexec-tools runs hostname binary in the case of fence_kdump. Since this
    is a trival dependency and should not block the kexec-tools installation
    if non-existent, using weak-dependency to resolve it.

commit 0311f6e25b
Author: Tao Liu <ltao@redhat.com>
Date:   Wed Jan 5 17:42:12 2022 +0800

    Set zstd as the default compression method for kdump initrd

    zstd has better compression ratio and time consumption balance.
    When no customized compression method specified in kdump.conf,
    we will use zstd as the default compression method.

    **The test method:

    I installed kexec-tools with and without the patch, executing the following
    command for 4 times, and calculate the averange time:

    $ rm -f /boot/initramfs-*kdump.img && time kdumpctl rebuild && \

224984355d try to reset kernel crashkernel when kexec-tools updates the default crashkernel value
Resolves: bz1895258
Upstream: Fedora
Conflict: None

commit 0adb0f4a8c
Author: Coiby Xu <coxu@redhat.com>
Date:   Wed Dec 1 15:33:13 2021 +0800

    try to reset kernel crashkernel when kexec-tools updates the default crashkernel value

    kexec-tools could update the default crashkernel value.
    When auto_reset_crashkernel=yes, reset kernel to new crashkernel
    value in the following two cases,
     - crashkernel=auto is found in the kernel cmdline
     - the kernel crashkernel was previously set by kexec-tools i.e.
       the kernel is using old default crashkernel value

    To tell if the user is using a custom value for the kernel crashkernel
    or not, we assume the user would never use the default crashkernel value
    as custom value. When kexec-tools gets updated,
     1. save the default crashkernel value of the older package to
        /tmp/crashkernel (for POWER system, /tmp/crashkernel_fadump is saved
        as well).
     2. If auto_reset_crashkernel=yes, iterate all installed kernels.
        For each kernel, compare its crashkernel value with the old
        default crashkernel and reset it if yes

    The implementation makes use of two RPM scriptlets [2],
     - %pre is run before a package is installed so we can use it to save
       old default crashkernel value
     - %post is run after a package installed so we can use it to try to reset
       kernel crashkernel

    There are several problems when running kdumpctl in the RPM scripts
    for CoreOS/Atomic/Silverblue, for example, the lock can't be acquired by
    kdumpctl, "rpm-ostree kargs" can't be run and etc.. So don't enable this
    feature for CoreOS/Atomic/Silverblue.

    Note latest shellcheck (0.8.0) gives false positives about the
    associative array as of this commit. And Fedora's shellcheck is 0.7.2
    and can't even correctly parse the shell code because of the associative
    array.

    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.)

    kdump/ppc64: suppress the error message "Could not find a registered notification tool" from servicelog_notify

    When kexec-tools is newly installed, kdump migration action hasn't
    registered and the following error could occur,
      INF dnf.rpm: Could not find a registered notification tool with the specified command ('/usr/lib/kdump/kdump-migrate-action.sh').

    "servicelog_notify --list" could list registered notification tools for
    a command but it outputs the above error as well. So simply redirect the
    error to /dev/null when running "servicelog_notify --remove".

    Merge kdump-error-handler.sh into kdump.sh

    kdump-error-handler.sh does nothing except calling three functions,
    it can be easily merged into kdump.sh by using a parameter to run the
    error handling routine.

    kdump-lib-initramfs.sh was created to hold the three shared functions
    and related code, so by merging these two files, kdump-lib-initramfs.sh
    can be simplified by a lot.

    Following up commits will clean up kdump-lib-initramfs.sh.

96a3fc1ac8 fadump: isolate fadump initramfs image within the default one
Resolves: bz1924115
Conflict: None
Upstream: Fedora

commit fa9201b240 (devel)

    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.

93ba58b136 Add a new hook: 92-crashkernel.install
Resolves: bz1974638
Upstream: Fedora
Conflict: Minor conflict in spec file resolved easily

commit 6463641935
Author: Kairui Song <kasong@redhat.com>
Date:   Thu Jun 10 13:06:23 2021 +0800

    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.
