Regards, -- Yves-Alexis Okay so whatever you decide w/ security team (retpoline fixes only or full 4.9.77) I can test if it helps.

Anyway if you want someone to test the updates please push the updated packages to stretch-p-u and I'll tell you if it works on my four boxes which are : - An Intel Core i7 4790 w/ NVidia blob 384.111 - An AMD Phenom 9850 w/ NVidia blob 384.111 - An Intel Core i7 4800MQ laptop - An Intel NUC Atom Apollo Lake Rgds, > > Regards, > -- > Yves-Alexis

Hi, work on 4.9.77 is mostly done, so yes I'd like to push it to stretch before next point relase. 4.9.78 is just out but I'm unsure if we want to hold it or not. > > I know this situation is quite exceptionnal, but all the Spectre story is. > I'm not sure backporting only the required changes for retpoline would be > that easy. That beeing said, retpoline support in the kernel is not enough. It also needs gcc fixes, which are not yet available, as far as I can tell. So while we can push an updated kernel to stretch, spectre won't be mitigated. Regards, -- Yves-Alexis signature.asc Description: This is a digitally signed message part
Bug#888263: Spectre : release kernel 4.9.77 to stretch before p-u
Package: linux-image-4.9.0-5-amd64 Version: 4.9.65-3+deb9u2 Severity: serious Tags: security Justification: root security hole Hi, Now that kernel release 4.9.77 has been released and contains the full retpoline fixes, could you please bring it to stretch before the next p-u ? I know this situation is quite exceptionnal, but all the Spectre story is. I'm not sure backporting only the required changes for retpoline would be that easy. Thanks a lot,
