"This update for kdump provides several fixes and enhancements :

  - Refresh kdumprd if /etc/hosts or /etc/nsswitch.conf is
    changed. (bsc#943214)

  - Add a separate systemd service to rebuild kdumprd at
    boot. (bsc#943214)

  - Improve network setup in the kdump environment by
    reading configuration from wicked by default (system
    configuration files are used as a fallback).
    (bsc#980328)

  - Use the last mount entry in kdump_get_mountpoints().
    (bsc#951844)

  - Remove 'notsc' from the kdump kernel command line.
    (bsc#973213)

  - Handle dump files with many program headers.
    (bsc#932339, bsc#970708)

  - Fall back to stat() if file type is DT_UNKNOWN.
    (bsc#964206)

  - Remove vm. sysctls from kdump initrd. (bsc#927451,
    bsc#987862)

  - Use the exit code of kexec, not that of 'local'.
    (bsc#984799)

  - Convert sysroot to a bind mount in kdump initrd.
    (bsc#976864)

  - Distinguish between Xenlinux (aka Xenified or SUSE) and
    pvops Xen kernels, as the latter can run on bare metal.
    (bsc#974270)

  - CVE-2016-5759: Use full path to dracut as argument to
    bash. (bsc#989972, bsc#990200)
