SUSE-SU-2016:2553-1

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)
