nopti	<reply> KPTI is a mitigation for the !Meltdown security issue. With some workloads on some processors, KPTI has a significant performance impact. KPTI can be disabled by adding "nopti" to the GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub. This should only be done if absolutely necessary because it will disable protections against Meltdown and thus allow any malicious user process to read memory and probably escalate to root.

spectre	<reply> Spectre is a security issue in almost all modern processors, which was released along with !Meltdown (but is not the same thing). While there are several initiatives underway to mitigate it, there is no "magic bullet" software fix. Ubuntu is monitoring ongoing efforts and will provide security updates as they become available. See !usn for security update notifications.	Added by dax Date: 2018-01-03 22:56:29 Last edited by dax Date: 2018-01-10 01:30:57 Requested 18 times
