50d77e1989 Use a customized emergency shell
Resolves: bz1901024
Upstream: Fedora
Conflict: None

commit 41980f30d9
Author: Kairui Song <kasong@redhat.com>
Date:   Mon Apr 26 17:09:57 2021 +0800

    Use a customized emergency shell

    Use a modified and minimized version of emergency shell.
    The differences of this kdump shell and dracut emergency shell are:

      - Kdump shell won't generate a rdsosreport automatically
      - Customized prompts
      - Never ask root password
      - Won't tangle with dracut's emergency_action. If emergency_action is
        set, dracut emergency shell will perform dracut's emergency_action
        instead of kdump final_action on exit.
      - If rd.shell=no is set, kdump shell will still work, dracut emergency
        shell won't, even if kdump failure_action is set to shell.

e5ccb87ef6 Don's try to restart dracut-initqueue if it's already there
Resolves: bz1901024
Upstream: Fedora
Conflict: None

commit 108258139a
Author: Kairui Song <kasong@redhat.com>
Date:   Mon Apr 26 17:09:55 2021 +0800

    Don's try to restart dracut-initqueue if it's already there

    kdump's dump_to_rootfs will try to start initqueue unconditionally.
    dump_to_rootfs will run after systemd isolate to emergency
    target, so this is currently accetable.

    But there is a problem when initqueue starts the emergency action
    because of initqueue timeout. dump_to_rootfs will start initqueue and
    lead to timeout again.

    So following patch will remove the previous isolation wrapper, and
    detect the service status here. Previous isolation makes the detection
    impossible. Now this detection will be valid and helpful to prevent
    double timeout or hang.

41f1d5b2e9 fadump: fix dump capture failure to root disk
Resolves: bz1952652
Upstream: fedora
Conflict: none

commit d0e9c51e0d
Author: Hari Bathini <hbathini@linux.ibm.com>
Date:   Thu Apr 22 18:21:59 2021 +0530

    fadump: fix dump capture failure to root disk

    If the dump target is the root disk, kdump scripts add an entry in
    /etc/fstab for root disk with /sysroot as the mount point. The root
    disk, passed through root=<> kernel commandline parameter, is mounted
    at /sysroot in read-only mode before switching from initial ramdisk.
    So, in fadump mode, a remount of /sysroot to read-write mode is needed
    to capture dump successfully, because /sysroot is already mounted as
    read-only based on root=<> boot parameter.

    Commit e8ef4db8ff ("Fix dump_fs mount point detection and fallback
    mount") removed initialization of $_op variable, the variable holding
    the options the dump target was mounted with, leading to the below
    error as remount was skipped:

      kdump[586]: saving to /sysroot/var/crash/127.0.0.1-2021-04-22-07:22:08/
      kdump.sh[587]: mkdir: cannot create directory '/sysroot/var/crash/127.0.0.1-2021-04-22-07:22:08/': Read-only file system
      kdump[589]: saving vmcore failed

    Restore $_op variable initialization in dump_fs() function to fix this.

    Fixes: e8ef4db8ff ("Fix dump_fs mount point detection and fallback mount")

134a7686ed Fix incorrect file permissions of vmcore-dmesg-incomplete.txt
Resolves: bz1955453
Upstream: fedora
Conflict: none

commit ca05b754af
Author: Tao Liu <ltao@redhat.com>
Date:   Mon May 10 22:10:26 2021 +0800

    Fix incorrect file permissions of vmcore-dmesg-incomplete.txt

    vmcore-dmesg-incomplete.txt is generated by shell redirection,
    which taking the default umask value. When dmesg collector exits
    with non-zero, the file will exist and anyone can have access to
    it.

    This patch fixed the issue by chmod the file, making it accessible
    only to its owner.

    Fix incorrect permissions on kdump dmesg file

    Also known as CVE-2021-20269. The kdump dmesg log files(kexec-dmesg.log,
