No major update this week. Ben H. has been busy upstream.
Timeline meltdown and spectre updates for CIP kernel
At this moment the impact of Spectre and Meltdown in modern architectures is incomplete as this table shows.
The initial fixes are stating to land upstream and being backported, as GKH stated in his post.
It is early yet to fully understand the strategy towards fixes backports beyond what upstream is doing. Once the current fixes are settle upstream, a discussion should be opened about what to do with the fixes that has not landed to 4.4, especially those related with ARM.
The original idea is to have a statement about Meltdown/Spectre issue from the CIP kernel maintainer next week.
Given the communication needs, the goal is to have a software statement by the end of the current week. TODO: Agustin
