54611cd628 Implement IP netmask calculation to replace "ipcalc -m"
Resolves: bz1947347
Upstream: Fedora
Conflict: None

commit 1ca1b71780
Author: Coiby Xu <coxu@redhat.com>

    Implement IP netmask calculation to replace "ipcalc -m"

    Recently, dracut-network drops depedency on dhcp-client which requires
    ipcalc. Thus the dependency chain
    "kexec-tools -> dracut-network -> dhcp-client -> ipcalc"
    is broken. When NIC is configured to a static IP, kexec-tools depended
    on "ipcalc -m" to get netmask. This commit implements the shell
    equivalent of "ipcalc -m".

    The following test code shows cal_netmask_by_prefix is consistent with
    "ipcalc -m",

        #!/bin/bash
        . dracut-module-setup.sh

        for i in {0..128}; do
            mask_expected=$(ipcalc -m fe::/$i| cut -d"=" -f2)
            mask_actual=$(cal_netmask_by_prefix $i "-6")
            if [[ "$mask_expected" != "$mask_actual" ]]; then
                echo "prefix="$i, "expected="$mask_expected, "acutal="$mask_actual
                exit
            fi
        done

        echo "IPv6 tests passed"

        for i in {0..32}; do
            mask_expected=$(ipcalc -m 8.8.8.8/$i| cut -d"=" -f2)
            mask_actual=$(cal_netmask_by_prefix $i "")
            if [[ "$mask_expected" != "$mask_actual" ]]; then
                echo "prefix="$i, "expected="$mask_expected, "acutal="$mask_actual
                exit
            fi
        done

        echo "IPv4 tests passed"

        i=-2
        res=$(cal_netmask_by_prefix "$i" "")
        if [[ $? -ne 1 ]]; then
            echo "cal_netmask_by_prefix should exit when prefix<0"
            exit
        fi

        res=$(cal_netmask_by_prefix "$i" "")
        if [[ $? -ne 1 ]]; then
            echo "cal_netmask_by_prefix should exit when prefix<0"
            exit
        fi

        i=33
        $(cal_netmask_by_prefix $i "")
        if [[ $? -ne 1 ]]; then
            echo "cal_netmask_by_prefix should exit when prefix>32 for IPv4"
            exit
        fi

        i=129
        $(cal_netmask_by_prefix $i "-6")
        if [[ $? -ne 1 ]]; then
            echo "cal_netmask_by_prefix should exit when prefix>128 for IPv4"
            exit
        fi

        echo "Bad prefixes tests passed"

        echo "All tests passed"

540d33a082 kdump-lib.sh: introduce functions to return recommened mem size
Resolves: bz1892558

Conflict: None

    kdump-lib.sh: introduce functions to return recommened mem size

    There is requirement to decide the recommended memory size for the current
    system. And the algorithm is based on /proc/iomem, so it can align with the
    algorithm used by reserve_crashkernel() in kernel.

910c20d3ce Fix incorrect vmcore permissions when dumped through ssh
Related: rhbz#1938165
Upstream: fedora
Conflict: none

commit 00785873ef
Author: Tao Liu <ltao@redhat.com>
Date:   Fri Mar 19 18:07:51 2021 +0800

    Fix incorrect vmcore permissions when dumped through ssh

    Previously when dumping vmcore to a remote machine through ssh,
    the files are created remotely and file permissions are taken
    from the default umask value, which making the files accessible to
    anyone on the remote machine.

    This patch fixed the security issue by setting a customized umask value
    before the file creation on the remote machine.

3371584d02 Fix incorrect permissions on kdump dmesg file
Resolves: rhbz#1938165
Upstream: fedora
Conflict: none

commit 91c802ff52
Author: Tao Liu <ltao@redhat.com>
Date:   Thu Mar 18 16:52:46 2021 +0800

    Fix incorrect permissions on kdump dmesg file

    Also known as CVE-2021-20269. The kdump dmesg log files(kexec-dmesg.log,
    vmcore-dmesg.txt) are generated by shell redirection, which take the
    default umask value, making the files readable for group and others.

    This patch chmod these files, making them only accessible to owner.
