Description

This update for dracut fixes the following issues :

Security issues fixed :

  • CVE-2016-8637: When the early microcode loading was enabled during initrd creation, the initrd would be read-only available for all users, allowing local users to retrieve secrets stored in the initial ramdisk. (bsc#1008340)

Non security issues fixed :

  • Remove zlib module as requirement. (bsc#1020063)

  • Unlimit TaskMax for xfs_repair in emergency shell. (bsc#1019938)

  • Resolve symbolic links for -i and -k parameters. (bsc#902375)

  • Enhance purge-kernels script to handle kgraft patches. (bsc#1017141)

  • Allow booting from degraded MD arrays with systemd. (bsc#1017695)

  • Allow booting on s390x with fips=1 on the kernel command line. (bnc#1021687)

  • Start multipath services before local-fs-pre.target. (bsc#1005410, bsc#1006118, bsc#1007925)

  • Fix /sbin/installkernel to handle kernel packages built with 'make bin-rpmpkg'. (bsc#1008648)
