[...] > this got kinda long, sorry ;) Well, that's a great response! I've tried to summarize your responses and those of others in the thread in the wiki, which gives us the following diff: https://wiki.debian.org/DebianSecurity/SpectreMeltdown?action=diff&rev2=30&rev1=26 You'll also noticed I flipped the "yellow" color back to "green" for Spectre v1. I'm not sure why this was yellow: I chose that color before because I felt this was only partially mitigated, but I feel that we have "as good as we can get" mitigation. >From what I understand, we'd need a full audit of the complete source code of the Debian archive (!) and, once that's done), a full rebuild with retpoline. That is not a realistic expectation and so I simply noted that we do not plan to do a full rebuild at this stage. Hutchings also added per-architecture tables and more details, thanks for that! Hopefully we're a little better in terms of documentation. I'd still like to see a better userland section, but I'm not sure where to start... Thanks for your help!
